From 5c1d1b74c5b2712370dcad5b17a4c6102c361d2e Mon Sep 17 00:00:00 2001 From: robobun <117481402+robobun@users.noreply.github.com> Date: Sat, 1 Aug 2026 10:48:23 +0000 Subject: [PATCH 001/304] bundler: resolve require('bindings')('') to the .node addon at build time The bindings npm package locates a native addon at runtime by walking up from the caller's __filename to the enclosing package.json and probing build/Release/.node (and a handful of other locations). Once the caller is bundled that walk starts from the bundle path, and in a --compile binary the virtual /$bunfs/... path has no package.json above it, so packages like sqlite3 fail with "Could not find module root given file". When bundling, detect require('bindings')('') with a literal addon name and emit a NativeBindings-tagged import record for instead. During import-record resolution, look up the enclosing package.json for the source file and probe the same directories bindings would (skipping the host-node- version/ABI-specific ones). When found, rewrite the record to a direct require() of the absolute .node path so the Napi loader embeds it in the standalone executable (or emits it as an asset with --outdir). When not found and the call is not inside try/catch, fail the build with a pointed error. Non-literal arguments are left untouched so existing behaviour is preserved.

The HardcodedModule alias lookup and onResolve plugin dispatch were reading it as one, so require('bindings')('zlib') matched node:zlib and any broad onResolve filter intercepted the record before it was rewritten. Guard both checks on tag != NativeBindings so the addon path is resolved first. Also suppress the not-found error when 'bindings' is marked external (the build should not newly fail in that configuration) and reword the remedy in the error message to point at externalising the enclosing package, which is the escape that works. --- src/bundler/bundle_v2.rs | 38 +++++++++++++++++++--------- src/resolver/resolver.rs | 2 +- test/bundler/bundler_compile.test.ts | 36 +++++++++++++++++++++++++- 3 files changed, 62 insertions(+), 14 deletions(-) diff --git a/src/bundler/bundle_v2.rs b/src/bundler/bundle_v2.rs index b45d5f221793..07ce58711644 100644 --- a/src/bundler/bundle_v2.rs +++ b/src/bundler/bundle_v2.rs @@ -5920,7 +5920,9 @@ pub mod bv2_impl { continue; } - if ctx.target.is_bun() { + if ctx.target.is_bun() + && import_record.tag != bun_ast::ImportRecordTag::NativeBindings + { if let Some(replacement) = bun_resolve_builtins::HardcodedModule::Alias::get( import_record.path.text, Target::Bun, @@ -5974,13 +5976,15 @@ pub mod bv2_impl { .insert(bun_ast::ImportRecordFlags::IS_EXTERNAL_WITHOUT_SIDE_EFFECTS); } - if self.enqueue_on_resolve_plugin_if_needed( - source.index.0, - import_record, - source.path.text, - i as u32, - ctx.target, - ) { + if import_record.tag != bun_ast::ImportRecordTag::NativeBindings + && self.enqueue_on_resolve_plugin_if_needed( + source.index.0, + import_record, + source.path.text, + i as u32, + ctx.target, + ) + { continue; } @@ -6053,9 +6057,19 @@ pub mod bv2_impl { } None => { import_record.path.is_disabled = true; - if !import_record - .flags - .contains(bun_ast::ImportRecordFlags::HANDLES_IMPORT_ERRORS) + let bindings_is_external = transpiler + .resolver + .is_external_pattern(b"bindings") + || transpiler + .resolver + .opts + .external + .node_modules + .contains(b"bindings"); + if !bindings_is_external + && !import_record + .flags + .contains(bun_ast::ImportRecordFlags::HANDLES_IMPORT_ERRORS) && !self.transpiler.options.ignore_module_resolution_errors { // SAFETY: log lives in DevServer/transpiler, disjoint from `self.graph`. @@ -6073,7 +6087,7 @@ pub mod bv2_impl { Some(source), import_record.range, format_args!( - "Could not locate native addon \"{}\" for the \"bindings\" package.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem `delete obj.prop` and `typeof undeclaredGlobal` inside a react-compiled function both lose their parse-time `E::UnaryFlags` on the round-trip through HIR, so the printer's `(0, ...)` guard (`src/js_printer/lib.rs:4003-4004`) re-wraps them: ```jsx import { useMemo } from "react"; export function useThing(props) { return useMemo(() => { const x = { a: props.a, b: props.b }; delete x.b; // prints `delete (0, x.b)` → no-op, returns true const k = "a"; delete x[k]; // prints `delete (0, x["a"])` → no-op return x; }, [props.a, props.b]); } export function useIsBrowser() { return useMemo(() => typeof window !== "undefined", []); // prints `typeof (0, window)` → ReferenceError under SSR } ``` ```console $ bun build entry.jsx --react-compiler --external='*' --target=browser ..., delete (0, x.b), delete (0, x["a"]), ... return typeof (0, window) !== "undefined"; ``` ## Cause `src/react_compiler/codegen.rs` rebuilt every `E::Unary` with `flags: UnaryFlags::empty()`: - `InstructionValue::PropertyDelete` / `InstructionValue::ComputedDelete` dropped `WAS_ORIGINALLY_DELETE_OF_IDENTIFIER_OR_PROPERTY_ACCESS`, so the printer wrapped every `delete ` as `delete (0, ...)`, which evaluates the property to a value and returns `true` without deleting. - `InstructionValue::UnaryExpression` dropped `WAS_ORIGINALLY_TYPEOF_IDENTIFIER`, so the printer wrapped `typeof undeclaredGlobal` as `typeof (0, undeclaredGlobal)`, which throws `ReferenceError` instead of returning `"undefined"`. `lower_unary` (`src/react_compiler/lowering/build_hir/expr.rs`) discarded `unary.flags` at construction time, so codegen had nothing to restore. ## Fix - **typeof**: thread `unary.flags` through HIR. `InstructionValue::UnaryExpression` gains a `bun_flags: E::UnaryFlags` field; lowering copies the visited node's flags in and codegen copies them back out. This preserves the visitor's own distinction between `typeof x` (flag set, no wrap) and `typeof (folded-to-x)` (flag unset, visitor already wrapped as a real `(0, x)` comma expression, stays throwing). - **delete**: set the flag unconditionally at both codegen sites, and gate `lower_unary`'s `EDot`/`EIndex` arms on `unary.flags` so a flagless operand (the visitor folded `delete (true ? a.b : c.d)` to a bare `EDot`) falls through to the existing "Only object properties can be deleted" bailout. That matches upstream's Babel plugin, which sees the unfolded `ConditionalExpression` and bails the same way, and keeps the spec no-op semantics for that edge case. - `E::UnaryFlags` gains `Debug` (the HIR enum derives `Debug`); the other `bitflags!` in `src/ast/` already do. Babel's reference output for the upstream `delete-property` / `delete-computed-property` fixtures is plain `delete x.b` / `delete x["b"]`, which this now matches. ## Verification ```console $ bun bd test test/bundler/transpiler/react-compiler.test.ts ``` New tests (`PropertyDeletePreservesReferenceSemantics`, `TypeofUnboundIdentifierPreservesFlag`) fail on main (`delete (0,` / `typeof (0, window)` in the output; runtime `{"a":1,"b":2,"c":3}` / `ReferenceError`) and pass with this change. `DeleteFoldedConditionalKeepsNoOpSemantics` guards the edge case that an earlier revision of this PR regressed.

The test set `cache = "cache"` in bunfig to give each case an isolated cache, but `scripts/runner.node.mjs` sets `BUN_INSTALL_CACHE_DIR` on the test process, `bunEnv` inherits it, and `fetch_cache_directory_path` consults that env var before the bunfig setting, so both concurrent `bun install` processes shared one cache directory. On Windows, the tarball-extraction retry path handles an occupied cache slot by renaming the existing entry into the temp dir and deleting it before retrying, so one process's post-rename verify can see `ENOENT` on an entry the other process just moved aside. That underlying race is #28062 (fix in progress in #33884). The POSIX path uses `renameat_concurrently_a`, which does not remove the existing entry, so the flake is Windows-only. Separately, under debug+ASAN each case took ~5s (two subprocess installs on 80-104 packages plus ~100 `Bun.Archive.write` calls for tarball synthesis in the registry server), right at the 5s default timeout. ### Fix - Override `BUN_INSTALL_CACHE_DIR` per test case in the spawn env so the intended isolation holds regardless of the ambient environment; drop the now-dead bunfig `cache` key and `mkdirSync`. - Run both installs with `--lockfile-only`. The `Lockfile::eql` comparison under test only needs a lockfile, so tarball download, extraction and linking are irrelevant. With no tarball fetch the registry server no longer needs to synthesize real tarballs, so the `Bun.Archive.write` path and the tarball route are removed (integrity is never verified on this path). ### Verification - Windows with CI-like env: 0/30 failures (was 12/15). - `bun bd test`: 5/5 pass, 0.8-1.8s per case (was timing out at 5s). - With the `src/install/lockfile.rs` change from #36578 reverted, both cases still fail with `lockfile had changes, but lockfile is frozen`, so the test continues to cover the original regression. --- **[stamp-90s]** gate passed · iteration 1 · 1 files touched

A terminal Ctrl+C signals the whole foreground process group. In a nested chain every `bun run` gets the terminal's SIGINT *and* forwards it to its child, so a runner in the middle receives the signal at least twice: ``` terminal -> pgroup SIGINT -> bun run outer, bun run inner, bun script.js bun run outer: forward SIGINT -> bun run inner (handler reset to SIG_DFL) bun run inner: forward SIGINT -> bun script.js (handler reset to SIG_DFL) bun run inner: 2nd SIGINT (from outer's forward) -> SIG_DFL -> killed bun run outer: wait4 sees inner died by SIGINT -> re-raise -> exit bun script.js: still running its 1s cleanup timer ``` A single level (`bun run inner` directly) works because the top-level runner only ever sees one SIGINT. ## Fix Drop `SA_RESETHAND`. The forwarding handler stays installed for the lifetime of the child, matching npm (the signal list and forwarding behavior were already modelled on npm per the existing comment). `Bun__unregisterSignalsForForwarding` restores the previous disposition once the child has exited, so the process-level behavior outside the wait is unchanged. While here, drop `SIGIOT` and `SIGPOLL` from the signal list: they are aliases of `SIGABRT` and `SIGIO`, so `REGISTER_SIGNAL` ran twice for the same signal number and the second call overwrote `previous_actions[N]` with the forwarding handler itself, which the unregister then "restored". With `SA_RESETHAND` gone that leaked handler would have been permanent rather than one-shot. Impact was essentially nil (SIGABRT is re-fixed by `reset_on_posix()` in release builds, and nothing sends SIGIO), but registering each signal number exactly once makes the unregister comment true. ## Verification New test in `test/regression/issue/14799.test.ts` spawns `bun run outer` -> `bun run inner` -> `bun script.js` in its own process group, sends SIGINT to the group, and asserts: | | before | after | | --- | --- | --- | | inner still alive when outer exits | `true` | `false` | | outer `exitCode` / `signalCode` | `130` / `SIGINT` | `0` / `null` | | stdout | `cleanup done` | `cleanup done` | ``` git stash push -- src/ && bun bd test test/regression/issue/14799.test.ts (fail) nested bun run waits for the child on SIGINT exitCode: 130, innerAliveAfterOuterExit: true, signalCode: SIGINT bun bd test test/regression/issue/14799.test.ts (pass) nested bun run waits for the child on SIGINT x5/5 ``` The existing `verify that we forward SIGINT from parent to child in bun run` and `bun run propagates SIGKILL` tests still pass. --- **[review]** gate passed · iteration 1 · 2 files touched

The `NewServer` Box is only freed once the JS wrapper's `finalize()` fires and `schedule_deinit()` enqueues the actual `deinit()` as a `ManagedTask`. When the wrapper survives to `lastChanceToFinalize` (`BUN_DESTRUCT_VM_ON_EXIT=1`, which the CI runner sets on ASAN lanes), `global_exit()` has already had its last event-loop tick. The enqueued task never runs, and `EventLoop::deinit()` drops the task box without a cleanup (`ManagedTask::new` sets `cleanup: None`). The 2104-byte `NewServer` Box, its `config.static_routes` Vec, the `html_bundle::Route` it refcounts, and the route's path strings are all orphaned. `Route.server: Cell>` points back at the server so LSan sees a pointer cycle and reports every allocation as indirect. The path has always existed, but before #35356 the per-tick GC sampler usually collected the wrapper during the handful of event-loop ticks between the test body and `global_exit()`, so `schedule_deinit()` ran while the loop was still live. With only the 1s idle-timer GC, a single fast test like this one reaches shutdown with the wrapper still alive more often (about half the PR builds since the merge). ## Fix `schedule_deinit()` now sets `DEINIT_SCHEDULED` and returns without enqueueing when `is_shutting_down()`. `finalize()` then frees the Box synchronously when the server has been fully drained: it unboxes via `Box::into_raw` first so the dealloc goes through the raw owning pointer rather than a `&mut self` frame (whose FnEntry protector would make the dealloc Stacked-Borrows UB, same pattern as `Listener::finalize` / `UDPSocket::finalize`). Every JSC handle on the Drop chain (`JSPromiseStrong`, `JsRef`, `UserRouteBuilder.callback: Strong`) funnels through `Strong::Impl::destroy`, which is a no-op past `is_shutting_down()`, so freeing here is safe. The inline free is gated on `TERMINATED`: `NewApp::destroy` runs `us_socket_group_deinit`, which unlinks the socket group from the loop's list without closing any sockets still in it. A graceful `stop()` only closes the listener and leaves keep-alive sockets open in the group; destroying the app there would orphan them (seen as a 280-byte `us_poll_t` direct leak on `vendor/elysia/test/core/before-handle-arrow.test.ts` with an earlier revision of this PR, and a `US_ASSERT(head_sockets==NULL)` abort on the debug build). `TERMINATED` is set only once `app.close()` has run, so the inline free is taken for abruptly-stopped servers (what `using server` does) and skipped for gracefully-stopped ones, which is identical to `main`'s behaviour for them. Other callers that can reach `schedule_deinit()` past shutdown (a last request draining inside `close_all_socket_groups`, which runs before `lastChanceToFinalize`) only set the flag and leave the Box, since `NewApp::destroy` there would delete the uws socket group mid-iteration. ## Verification Two ASAN-only subprocess tests added: - abrupt `stop(true)` of a dev server with an HTML route under `BUN_DESTRUCT_VM_ON_EXIT=1` + `detect_leaks=1`: fails on `main` with the 7-allocation LSan report above; passes with this change. - graceful `stop()` of a plain server with a keep-alive client connection: passes on both `main` and this change (asserts `us_socket_group_deinit`'s `head_sockets==NULL` precondition, which an earlier revision of this change violated). --- **no test proof** · iteration 2 · Platform-specific test(s) that do not run on this machine.

A promise whose resolver is assigned on the line after `.close()` therefore never resolved, and the process then sat at 100% CPU awaiting it: ```js ws.onclose = () => resolve?.(); ws.close(3000); const closePromise = new Promise(r => (resolve = r)); await closePromise; // hangs at 100% CPU in Bun; resolves in Node/Deno/browsers ``` ## Cause `WebSocket::close()` calls Rust `close()` -> `send_close_with_body()` -> `dispatch_close()` -> C++ `WebSocket::didClose()`, all on the same stack, and `didClose()` had a fast path that dispatched the `CloseEvent` directly when a listener was attached. `terminate()` has the same shape via Rust `cancel()` -> `dispatch_abrupt_close()` -> `didFailWithErrorCode()` -> `didReceiveClose()`. Per the [WHATWG WebSocket spec](https://websockets.spec.whatwg.org/#feedback-from-the-protocol) the user agent must **queue a task** to set `readyState` to `CLOSED` and fire the `close` event. ## Fix `didClose()` and `didReceiveClose()` now always `postTask()` the `CLOSED` transition and the `CloseEvent` dispatch. `m_state` moves to `CLOSING` synchronously first so `send()`/`ping()`/`pong()` called before the queued task runs take their `CLOSING` branch instead of reaching `sendWebSocketData()` with `m_connectedWebSocketKind == None` (which would `RELEASE_ASSERT_NOT_REACHED()`). Observable changes, both matching Node/Deno/browsers: - `readyState` is `CLOSING` (2) immediately after `close()`/`terminate()` returns, not `CLOSED` (3). - `onclose` fires after the current synchronous run-to-completion. With the close event queued as a task, the repro's close promise settles and the hang (and the 100% CPU spin while awaiting it) is gone. Earlier iterations of this PR also made `EventLoop::wait_for_promise()` bail out when a promise can never settle, to stop the pre-existing 100% CPU spin on `await new Promise(() => {})`-style waits. Review and CI showed the "nothing can settle this" predicate is wrong in at least three independent ways (a prior unhandled error, registered-but-unref'd polls on both POSIX and Windows, and off-thread JSC deferred work such as `WebAssembly.compileStreaming`), each needing platform-specific accounting, and any gap converts a busy-wait into a spurious user-visible failure (CI caught regressions in `spawn.test.ts` and `wasm-streaming.test.ts`). That hardening is orthogonal to this issue and was reverted; it needs its own PR with a properly designed predicate. ## Verification ``` # before (bun 1.4.0) $ bun repro.js Close: 3000 resolveAssigned: false after close(), readyState: 3 # ...hangs at 100% CPU # after $ bun-debug repro.js after close(), readyState: 2 Close: 3000 resolveAssigned: true done ``` `test/js/web/websocket/websocket-close-async-dispatch.test.ts` covers `close()` and `terminate()`, a `send()`-between-close-and-event check for the `CLOSING` transition, and the original hanging repro in a subprocess.

**root cause** · written by the author bot The root cause was that Bun's WebSocket fired the close event synchronously inside close() and terminate(), so readyState jumped straight to CLOSED and any close listener or promise registered after the call could never be triggered, causing the hang in issue #15665. The fix moves close and error event dispatch in didClose and didReceiveClose onto the script execution context task queue, with the state set to CLOSING synchronously so intervening send() or ping() calls take the correct branch and state guards plus pending-activity balancing prevent double dispatch.

Maybe you need to "bun install"? at node_modules/lib/index.js:6:21 ``` At runtime the catch handler only runs when the try body threw, so when `require('pkg')` resolves, `require('pkg/sub.cjs')` is unreachable. The build fails on dead code. The original #14509 report hit this via a dependency that wrapped `require('axios')` / `require('axios/dist/node/axios.cjs')` this way; older axios versions did not export `./dist/node/axios.cjs` so the fallback path was unresolvable. ## Cause `s_try` in `src/js_parser/visit/visit_stmt.rs` increments `fn_or_arrow_data_visit.try_body_count` around the `try` body only. `transpose_require` / `transpose_require_resolve_known_string` / `transpose_import_expr` use that counter to set `ImportRecordFlags::HANDLES_IMPORT_ERRORS` on the import record, which is what makes `bundle_v2` emit a runtime `throw` instead of a hard "Could not resolve" error. A `require()` in the catch handler never got the flag. ## Fix Increment `try_body_count` around the catch body as well. An unresolvable `require()` / `require.resolve()` / `await import()` in a catch handler now bundles as a runtime throw, matching what the same code does under `bun run` / Node. The `finally` body is left alone: it always executes, so an unresolved require there stays a bundle error. Setting `HANDLES_IMPORT_ERRORS` on the catch body would otherwise have flipped resolved-but-disabled paths (`"browser": {"pkg": false}` remaps, node builtins under `--target=browser`) from the empty-module stub to a throw-IIFE, crashing bundles that previously ran clean. The printer was conflating "resolve failed" with "intentionally disabled" via `path.is_disabled`. A new `ImportRecordFlags::WAS_UNRESOLVED` bit, set at the three resolve-failure sites, lets the printer emit the runtime throw only for actual resolve failures; an intentionally-disabled path keeps the empty-module stub in both the try and catch body. This also aligns the try-body case with esbuild, which always emits `{}` for a disabled path regardless of try/catch. esbuild only covers the `try` body and hard-errors on the catch body. The divergence only widens the set of inputs that bundle successfully. ## Verification Nine new cases in `test/bundler/bundler_edgecase.test.ts`: - `RequireInCatchBody`: subpath blocked by `exports` map, try body resolves → bundles, prints try-body value - `RequireInCatchBodyFromNodeModules`: same pattern inside `node_modules` (the #14509 shape) - `RequireInCatchBodyBothUnresolved`: neither resolves → bundles, catch-body require throws at runtime with the catch-body specifier in the message - `RequireResolveInCatchBody` / `AwaitImportInCatchBody`: `require.resolve` / `await import()` variants - `RequireInFinallyStillErrors`: `try {} catch {} finally { require('x') }` still hard-errors - `RequireAfterCatchBodyStillErrors`: a require after the try/catch still hard-errors (pins the catch-body counter decrement) - `RequireDisabledInCatchBodyStaysEmpty` / `RequireDisabledInTryBodyStaysEmpty`: `"browser": false` remap and node builtin under `--target=browser` keep the empty-module stub in both bodies ``` $ USE_SYSTEM_BUN=1 bun test test/bundler/bundler_edgecase.test.ts -t "InCatchBody|InFinallyStillErrors|AfterCatchBody|InTryBodyStays" 2 pass 7 fail $ bun bd test test/bundler/bundler_edgecase.test.ts -t "InCatchBody|InFinallyStillErrors|AfterCatchBody|InTryBodyStays" 9 pass 0 fail ``` `bundler_edgecase`, `bundler_browser`, `bundler_cjs`, `bundler_cjs2esm`, `bundler_allow_unresolved`, `esbuild/default`, and `esbuild/packagejson` all pass. --- **no test proof** · iteration 2 · Platform-specific test(s) that do not run on this machine.

Every symbol was verified to have zero callers across `src/` and `build/debug/codegen/`, and the full debug build links cleanly. No overlap with any open dead-code PR (#35437, #35559, #35775, #35880, #36115, #36178, #36237, #36318, #36621, #36742). ### Whole files deleted - `webcore/DOMJITCheckDOM.h` (98 LOC): only includer was `JSEventDOMJIT.cpp` - `webcore/JSEventDOMJIT.cpp` (43 LOC): defined `checkSubClassSnippetForJSEvent`, whose sole reference in `JSEvent.cpp:242` was behind `#if 0` (nullptr used instead) - `webcore/DOMJITHelpers.cpp` (57 LOC): every function body was already commented out; compiled to an empty namespace - `webcore/JSDOMConvertSerializedScriptValue.h` (50 LOC): only includer was the `JSDOMConvert.h` umbrella; `IDLSerializedScriptValue<>` was never instantiated anywhere ### webcore/DOMJITHelpers.h Removed the entire `WebCore::DOMJIT` namespace body (~184 LOC: `branchIf*`, `toWrapper`, `tryLookUpWrapperCache`, `operationToJSNode`/`operationToJSContainerNode` declarations, and ~60 LOC of commented-out helpers). All 7 remaining includers (`generate-classes.ts` output, `JSBuffer.cpp`, `JSPerformance.cpp`, `JSTextEncoder.cpp`, `JSFFIFunction.cpp`, `JSSQLStatement.cpp`, `ZigGeneratedCode.cpp`) use only `JSC::DOMJIT::*` from JavaScriptCore headers, never `WebCore::DOMJIT::*`. The transitive `#include`s are kept. ### webcore/EventContext.{h,cpp} Removed `handleLocalEvents`, `node()`, `relatedTarget()`, `setRelatedTarget`, `isMouseOrFocusEventContext`, `isTouchEventContext`, `isWindowContext`, `isUnreachableNode`, the `(Type, Node&, ...)` constructor overload, the `Type` enum and `m_type` field, `m_relatedTarget`, `m_contextNodeIsFormElement`, and all `TOUCH_EVENTS` / commented-out blocks. Only `currentTarget()` / `closedShadowDepth()` / `target()` are reachable (via `EventPath::computePathUnclosedToTarget`). ### webcore/EventPath.{h,cpp} Removed the empty `EventPath(Node&, Event&)` constructor, `contextAt`, `eventTargetRespectingTargetRules`, the `buildPath` / `setRelatedTarget` declarations (never defined), the `Touch` forward decl and `TOUCH_EVENTS` block. ### webcore/EventListenerMap.{h,cpp} Removed `removeFirstEventListenerCreatedFromMarkup`, `copyEventListenersNotCreatedFromMarkupToTarget`, and their file-local static helpers. WebKit markup-listener transfer helpers with zero callers in Bun. ### ErrorCode.{h,cpp} - `Bun::toJS(JSGlobalObject*, ErrorCode)`: declared, never defined, never called - `INVALID_FILE_URL_HOST(..., const ASCIILiteral)` overload: not declared in the header, so the two call sites in `BunObject.cpp` bind to the `const WTF::String&` overload - `CRYPTO_JWK_UNSUPPORTED_CURVE(..., const WTF::String&)` overload: the only call site in `KeyObject.cpp` passes `(ASCIILiteral, const char*)`, matching the other overload - `Message::ERR_INVALID_ARG_TYPE(..., const ZigString*, const ZigString*, JSValue)` overload: zero callers ### DOMException.{h,cpp} Removed `create(const Exception&)` (zero callers) and the static `name(ExceptionCode)` / `message(ExceptionCode)` helpers (zero callers; `description(ec).name` is used directly where needed). ### CookieMap.{h,cpp} Removed `struct CookieStoreGetOptions` (zero references), `getAll()` (not in the `JSCookieMap` prototype table; `toJSON()` enumerates directly), and the private `CookieMap(Vector>&&)` constructor (zero `adoptRef` sites use it). ### DOMFormData.{h,cpp} Removed `clone()`; zero callers. ### Single-line declarations - `Cookie.h`: `isValidCookieValue` (declared, never defined; the trailing comment already said "this isn't needed") - `ImportMetaObject.h`: `createRequireFunction` (declared, never defined) - `JSCommonJSModule.h`: `setSourceCode` (declared, never defined), `clearSourceCode`, `idOrDot` - `Sink.h`: `numberOfSinkIDs` constexpr - `ProcessBindingTTYWrap.cpp`: duplicate forward declaration of `Process_functionInternalGetWindowSize` (already declared via `JSC_DECLARE_HOST_FUNCTION` in the header) ### Also scanned, nothing confidently dead `src/http/`, `src/ast/`, `src/semver/`, `src/event_loop/`, `src/bun_core/`, `src/threading/`, `src/runtime/bake/dev_server/`, `src/js/thirdparty/`. All recently swept and clean. ### Intentionally not touched (possible followups) - `InspectorHTTPServerAgent::{requestWillBeSent,responseReceived,bodyChunkReceived,requestFinished,requestHandlerException}` and `InspectorBunFrontendDevServerAgent::{clientErrorReported,graphUpdate}`: look like in-progress inspector scaffolding with matching Rust-side extern declarations; left alone - `webcore/streams/CrossRealmTransform.cpp` stubs: explicitly documented as frozen-ABI placeholders for transferable streams - `JSEventListener::wasCreatedFromMarkup()` and `m_wasCreatedFromMarkup`: now the only readers are gone, but removing the bitfield changes class layout; left for a separate pass - `webcore/ResourceLoadTiming.h`: only includers are `ResourceTiming.{h,cpp}` which #36621 modifies; avoided to prevent merge conflicts ### Verification - `rg -w src/ build/debug/codegen/` returned only the definition for every removed item - `bun bd` builds and links - Smoke tests: `test/js/bun/cookie/cookie-map.test.ts`, `test/js/bun/globals.test.js`, `test/js/web/abort/abort.test.ts`, `test/js/web/fetch/body.test.ts -t FormData` all pass - `test/internal/source-lints/dead-symbols-domjit-eventpath-errorcode.test.ts` asserts the removed symbols do not reappear --- **[review]** gate passed · iteration 4 · 29 files touched

Every removed item was verified to have zero references across `src/` and `build/debug/codegen/`, then confirmed by a clean `bun bd` build and `bun run rust:check-all` (10/10 targets). ## C++ (`src/jsc/bindings/`) ### napi - `Napi::generateSourceCode()` (napi.cpp, napi.h): 26 LOC, zero callers. `rg generateSourceCode src/ build/debug/codegen/` finds only the definition and declaration. The `namespace JSC { JSGlobalObject; JSSourceCode; }` forward-decl block that sat above it is dropped with it. - `NapiWeakValue::isSet`/`isPrimitive`/`isCell`/`isString`/`cell()`/`primitive()`/`string()` (napi.h): accessor set never called; only `get()` is used. `NapiRef.cpp` explicitly avoids `isSet()`; the two comment lines there that referenced it are dropped too. - `NapiClass::destroy` (napi.h): unreachable with `needsDestruction = DoesNotNeedDestruction` on the same class. ### NodeVM - `NodeVMGlobalObject::clearContextifiedObject()`: zero callers. - `NodeVMModuleRequest::addImportAttribute` + `specifier(WTF::String)` setter: zero callers (only the getter is used). - `NodeVMSourceTextModule::hasModuleRecord` / `NodeVMSyntheticModule::hasModuleRecord`: zero callers (`moduleRecordIfExists()` covers the same check). - `NodeVMScript::cachedBytecode()`: zero callers; the field is accessed directly. ### JSBufferList / JSStringDecoder - `JSBufferListConstructor::initializeProperties`: empty body, never called. - `JSBufferList::destroy(JSCell*)`: unreachable on a `JSNonFinalObject` without `NeedsDestruction`. - `JSStringDecoderConstructor::initializeProperties`: never called; `finishCreation` (cpp:552) already sets name/length/prototype. ### BunClientData - `JSVMClientData::outputConstraintSpaces()` / `forEachOutputConstraintSpace()` / `m_outputConstraintSpaces`: duplicates of the `JSHeapData` members at the top of the file. Both real callers (`BunGCOutputConstraint.cpp:126` and `BunClientData.h:227`) dispatch on `heapData`, never on `JSVMClientData`. ### EventLoopTask - `m_isCleanupTask` field, `isCleanupTask()` getter, `CleanupTaskTag` constructor: the bool is written in every constructor but never read. `DeleteCallbackDataTask` now uses the primary templated constructor (identical behaviour). ### initialValues() statics - `JSNextTickQueue::initialValues()`, `PendingVirtualModuleResult::initialValues()` (ModuleLoader.h), `MockWithImplementationCleanupData::initialValues()` (JSMockFunction.h): never invoked; each `finishCreation` sets every internal field directly. `BunStreamSource::initialValues()` is kept (live caller at BunStreamSource.cpp:57). ### Misc - `JSEnvironmentVariableMap.cpp`: `jsSetterEnvironmentVariable` (registered with `nullptr`; only referenced in a comment, which is updated). - `JSBuffer.cpp`: commented-out `jsBufferPrototypeToStringWithoutTypeChecks` DOMJIT block (23 LOC, unchanged since Jan 2025). - `blob.h`: unused `BlobRef` type alias (`BlobRefPtr` is the one used). - `Bindgen/IDLTypes.h`: unused `IsIDLStrongAny` trait. ## Rust - `src/zlib/error.rs` (whole file, 31 LOC): defines `Error`/`Result` that nothing imports; the crate uses `ZlibError` from `lib.rs` instead. `rg 'bun_zlib::Error|bun_zlib::Result|zlib::error::'` across `src/` returns nothing. The `thiserror` dep it required is dropped from `src/zlib/Cargo.toml`. - `src/zlib/lib.rs`: dropped `Byte`/`gzFile`/`struct_gzFile_s`/`voidpf` from the `bun_zlib_sys::shared` re-export (zero Rust-side references), and the now no-op `#[allow(...)]` above it. - `src/io/windows_event_loop.rs`: `FilePoll::ref_`/`activate`/`can_ref` (30 LOC). No caller targets `FilePoll` for any of these; all `.ref_()`/`.activate()` call sites in the tree dispatch on `KeepAlive`, `Source`, `Pipe`, `Timer`, or `Progress`. The `declare_scope!(FilePoll)`/`declare_scope!(KeepAlive)` statics that only those methods logged through are dropped, and the stale `ref()` reference in the `disable_keeping_process_alive` doc is reworded. Verified on all 10 `rust:check-all` targets including both Windows triples. - `src/io/posix_event_loop.rs`: the posix `FilePoll::ref_` sibling (same justification), and the `declare_scope!(KeepAlive)` static with zero `scoped_log!` callers. - `src/install/lockfile/bun.lock.rs`: commented-out `Stringifier::save` stub. - `src/install/lockfile/Buffers.rs`: four empty `#[cfg(debug_assertions)] { /* commented print */ }` blocks on the save side, and the three orphaned `let _pos = stream.pos` bindings on the load side that fed them. ## TypeScript - `src/js/node/net.ts`: `kpendingRead` private `Symbol()` (defined, written once as `this[kpendingRead] = undefined`, never read). `kServerSocket` was initially removed too but **restored** in a93d2fa48e: the write `clientHandle[kServerSocket] = handle` is a GC retention edge from accepted socket handle to native Listener, and removing it crashed `sql-close-pending-connection.test.ts` on 6 CI lanes (build #87459) via `Listener::finalize` firing JS `on_close` during a GC sweep. A two-line comment now documents why the symbol exists; the underlying Listener-finalizer-calls-JS-during-sweep issue is tracked separately. ## Verification ``` $ bun bd [build] done $ bun run rust:check-all 10 ok, 0 failed, 0 skipped (of 10) $ bun bd test test/internal/source-lints/dead-symbols-napi-nodevm-libuv.test.ts 3 pass, 0 fail ``` Smoke tests on `test/js/node/vm`, `test/js/node/string_decoder`, `test/js/node/net`, `test/js/sql/sql-close-pending-connection.test.ts`, and `test/js/node/process -t env` show identical pass/fail counts with and without this diff. ## Notes - The vendored libuv headers (`src/jsc/bindings/libuv/uv/*`) are not touched (reverted in 4dd5a9973d per review). - `napi.cpp` also appears in #35775, which removes different symbols (`napi_set_ref`, `napi_internal_get_version`); no line overlap. - `src/zlib/Cargo.toml` also appears in #35880, which removes different deps (bstr/scopeguard/etc.); no deletion overlap. - `src/io/posix_event_loop.rs` also appears in #35880 at lines 1562+; this PR touches line 562, no overlap. - Areas scanned with nothing confidently dead (left alone): `src/http/` (HTTP client), `src/valkey/`, `src/patch/`, `src/semver/`, `src/semver_jsc/`. --- **[review]** gate passed · iteration 5 · 34 files touched

From 52753f29f56499542d8096bc94da18d396c9c95b Mon Sep 17 00:00:00 2001 From: robobun Date: Sun, 2 Aug 2026 00:55:32 -0700 Subject: [PATCH 019/304] Remove dead code from webcrypto C++, sqlite bindings, and Rust runtime (#36178) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Dead-code sweep across `src/jsc/bindings/webcrypto/`, `src/jsc/bindings/sqlite/`, and several Rust crates. Net -678 LOC (46 files, +117/-795; additions are the source-lint test). Each symbol was verified with `rg` across `src/` and `build/debug/codegen/` to have zero references outside its own definition, then the build confirmed it. ## webcrypto C++ (WebKit vestige) - **`SerializedCryptoKeyWrap.{h,cpp}`** (whole files): `defaultWebCryptoMasterKey`/`wrapSerializedCryptoKey`/`unwrapSerializedCryptoKey` have zero callers; the header is included only by its own `.cpp`. Bun's `SerializedScriptValue` serializes `CryptoKey` inline and links to the WebKit source in a comment instead of calling these. - **`platformSignWithAlgorithm`/`platformVerifyWithAlgorithm`** on `CryptoAlgorithmHMAC`, `CryptoAlgorithmRSASSA_PKCS1_v1_5`, `CryptoAlgorithmRSA_PSS`: `SubtleCrypto` only reaches `platformSign`/`platformVerify` (which read the hash off the key). The `WithAlgorithm` overloads that take an explicit `CryptoAlgorithmIdentifier` are never called. - **`CryptoAlgorithmRSASSA_PKCS1_v1_5::{platformSignNoAlgorithm, platformVerifyRecover}`**: zero callers. - **`CryptoKeyHMAC::generateFromBytes`**: zero callers (`generate()` is the only entry). - **`CryptoKeyOKP::{importPublicJwk, namedCurveString, isEd25519PrivateKey, exportKeySizeInBits}`**: zero callers. The EC flavour of `namedCurveString` is live; only the OKP one is dead. - **`CryptoKeyEC::keySizeInBytes`**: every call site computes `(keySizeInBits()+7)/8` locally into a variable. - **`convertDictionary<>` for 7 output-only dicts** (`CryptoKeyPair`, `Crypto{Aes,Ec,Hmac,Rsa,RsaHashed,}KeyAlgorithm`): these are `CryptoKey.algorithm`-shaped return values. Only `convertDictionaryToJS` (C++ → JS) is reachable via `toJS>`; nothing ever parses them from JS, so `convertDictionary<>` (JS → C++) is dead. The two `convert>` calls were inside the now-removed `CryptoHmacKeyAlgorithm`/`CryptoRsaHashedKeyAlgorithm` converters. - **`parseEnumeration`/`expectedEnumerationValues`**: only `toJS>` is reached; no `convert<>` path instantiates the parse direction. - **`convertEnumerationToString`/`convertEnumerationToJS`**: `KeyFormat` is input-only (parsed via `parseKeyFormatFromString`); nothing serializes it back to JS. - **`#if 0` CommonCrypto and `#if USE(GCRYPT)` blocks** in `CryptoKey{EC,RSA}.h`: Bun only builds the `USE(OPENSSL)` path. - **Misc one-liners**: `CryptoDigest::toHexString` (declared, never defined), `class PromiseWrapper;` forward decl, `SubtleCrypto::createPtr`, `bytesNeededForEncodedLength`, `IntegerMark`, `Version[]`. ## sqlite C++ - `jsSQLStatementExecuteStatementFunction`: orphan `JSC_DECLARE_HOST_FUNCTION` with no definition since 2022. - `lazy_sqlite3_column_bytes16`: typedef + `inline` pointer with no `#define` alias, no `dlsym` load, no callers. ## Rust - **`src/runtime/node/node_error_binding.rs`** (whole file + `pub mod` decl): both macro-generated functions (`ERR_INVALID_HANDLE_TYPE`, `ERR_CHILD_CLOSED_BEFORE_REPLY`) have zero callers in Rust or generated code. The JS-side `$ERR_INVALID_HANDLE_TYPE()` in `src/js/builtins/Ipc.ts` is served by the C++ `ErrorCode` table (`ErrorCode.cpp`), not this module. - **`impl Default for PBKDF2`**: only ever constructed via struct literal at `PBKDF2.rs:187`; `bun_jsc::ThreadSafe::adopt` requires `Unprotect`, not `Default`. - **`impl Default for StaticCryptoHasher`**: `constructor()` builds the struct directly; no generic bound requires `Default`. - **`impl Default for RefCountedStr`**: only ever constructed via `init(Box<[u8]>)`; never `Default`, never in a `#[derive(Default)]` container, never `mem::take`'d. - **`impl Default for UserInfoOptions`**: only ever received as `*const` from C++ (`hw_exports.rs`); never Rust-constructed. ## Verification - `rg ` across `src/` and `build/debug/codegen/` for every removed item - `bun bd` builds clean - `bun run rust:check-all` passes all targets - `bun bd test test/js/web/crypto/web-crypto.test.ts` : 93 pass / 0 fail - `bun bd test test/js/bun/sqlite/sqlite.test.js` : 98 pass / 0 fail - `bun bd test test/js/node/crypto/crypto.test.ts` : 369 pass / 0 fail - `test/internal/source-lints/dead-symbols-webcrypto-node.test.ts` fails on `main`, passes on this branch ## Follow-ups (not in this diff) - `src/platform/darwin.rs` (~236 LOC) appears fully unreferenced: `src/perf` uses the signpost stubs in `bun_sys::darwin` instead. Left alone because the `bun_sys` comment describes it as the "full" implementation and deleting it may make a future signpost wiring harder; flagging for a human call. - `src/jsc/bindings/webcrypto/*.idl` (29 files, ~1055 LOC) are not in any build rule but were touched recently for ML-DSA/ML-KEM, so they may be kept as regeneration reference. --- **[review]** gate passed · iteration 2 · 46 files touched

No file overlaps with the other open dead-code PRs (#34965, #34759, #35437, #35559, #35775, #35880, #36115, #36178, #36237). ## C++ bindings (~620 lines) - **`DecodeEscapeSequences.h`** (whole file, 187 lines): only `#include` was `TextEncoding.cpp`, whose only consumer `decodeURLEscapeSequences()` is itself dead. - **`TextEncoding.{cpp,h}`**: `domName`, `usesVisualOrdering`, `isJapanese`, `isNonByteBasedEncoding`, `isUTF7Encoding`, `closestByteBasedEquivalent`, `encodingForFormSubmissionOrURLParsing`, `ASCIIEncoding`, `Latin1Encoding`, `UTF16BigEndianEncoding`, `UTF16LittleEndianEncoding`, `WindowsLatin1Encoding`, `decodeURLEscapeSequences`, `UTF7Encoding`, `isByteBasedEncoding`. These formed a closed call graph with no outside caller; only `UTF8Encoding()` remains. - **`TextEncodingRegistry.{cpp,h}`**: `isJapaneseEncoding` + `japaneseEncodings()` static set + its 14 `addEncodingName` calls, `noExtendedTextEncodingNameUsed`, `defaultTextEncodingNameForSystemLanguage`, `webDefaultCFStringEncoding` decl, and the `CoreFoundation.h` include. All were only reached from the removed `TextEncoding` methods. - **`JSDOMExceptionHandling.{cpp,h}`**: `retrieveErrorMessageWithoutName`, `reportCurrentException`, `throwNotSupportedError`, `throwInvalidStateError`, `throwSecurityError`, `throwAttributeTypeError`, `makeUnsupportedIndexedSetterErrorMessage`, `throwDOMSyntaxError`, `reportExceptionIfJSDOMWindow`, and the now-orphaned static `throwTypeError` helper. `rg` across `src/` and `build/debug/codegen/` shows zero callers outside decl/defn. - **`DOMURL.{cpp,h}`**: `DOMURL::createObjectURL`/`revokeObjectURL`/`createPublicURL` C++ stubs, the `URLRegistrable`/`Blob` placeholder classes, and the commented-out includes. Real implementations are `Bun__createObjectURL`/`Bun__revokeObjectURL` in Rust; the C++ stubs were only referenced from commented-out code in `JSDOMURL.cpp`. - **`webcore/JSDOMURL.cpp`**: `jsDOMURLConstructorFunction_createObjectURL` / `_revokeObjectURL` / `_createObjectURL1Body` / `_revokeObjectURLBody` / `_createObjectURLOverloadDispatcher` and their forward decls. The hash table at `:140-141` routes to `Bun__createObjectURL`/`Bun__revokeObjectURL` instead. - **`DOMWrapperWorld-class.h` / `DOMWrapperWorld.cpp`**: `clearWrappers`, `didCreateWindowProxy`, `didDestroyWindowProxy`, `setShadowRootIsAlwaysOpen`/`shadowRootIsAlwaysOpen`, `disableLegacyOverrideBuiltInsBehavior`/`shouldDisableLegacyOverrideBuiltInsBehavior`, `m_jsWindowProxies`, `m_shadowRootIsAlwaysOpen`, `m_shouldDisableLegacyOverrideBuiltInsBehavior`, `class WindowProxy` fwd decl. `WindowProxy` is never defined. - **`ActiveDOMCallback.{cpp,h}`**: `activeDOMObjectsAreSuspended`/`activeDOMObjectAreStopped`. Only external references are in commented-out code in `JSDOMPromiseDeferred.cpp` and `ActiveDOMObject.cpp`. ## src/js internals (~370 lines) - **`internal/assert/utils.ts`**: 230 lines of commented-out acorn-based source-parsing scaffolding (`findColumn`/`getCode`/`parseCode`/`escapeSequencesRegExp`/`meta`/`escapeFn`) plus the `getErrMessage()` body, which always returned `undefined`. Inlined `undefined` at its one call site. Blame: 2025-01-10. - **`internal/util/inspect.js`**: commented-out `stylizeWithColor`/`stylizeWithHTML`/`entities`/`escapeHTML` block annotated "unused without stylizeWithHTML". Blame: 2023-09-28. - **`node/_http_server.ts`**: commented-out `fetch(req, _server)` handler inside `Bun.serve({...})`, superseded by native dispatch. Commented out 2025-04-21. - **`internal/cluster/primary.ts`**: commented-out `inspectPort`/`isUsingInspector` block. Blame: 2024-08-18. - **`internal/streams/utils.ts`**: `isReadableEnded` (exported from an internal module, zero consumers across `src/` and codegen). - **`internal/sql/shared.ts`**: `isOptionsOfAdapter`/`assertIsOptionsOfAdapter` (zero consumers). - **`internal/primordials.js`**: `SafePromiseAll` + `arrayToSafePromiseIterable` + `PromiseAll` + `ArrayPrototypeMap`. Only `SafePromiseAllReturnVoid`/`ReturnArrayLike` are consumed, via `safePromiseAllCollect` which does not use these. - **`internal/validators.ts`**: `validateInternalField` + its `ObjectPrototypeHasOwnProperty` capture (zero consumers). ## Rust (~190 lines) - **`http_types/h2.rs`**: `FullSettingsPayload` (struct + `Pod`/`Zeroable`/`Default`/`BYTE_SIZE`, ~50 lines). `pub(crate)` with zero references; `runtime/api/bun/h2_frame_parser.rs` has its own local copy and does not import this one. Also `StreamPriority::from` + its `Pod`/`Zeroable` impls, `UInt31WithReserved::init`, and `SettingsType::SETTINGS_ENABLE_CONNECT_PROTOCOL` (only used by the removed `FullSettingsPayload::default`). - **`http_types/mime_type_list_enum.rs`**: `MimeTypeList::{as_str, len}`. Callers use `<&'static str>::from(entry)` and slice `.len()` on `Table::ALL` instead. - **`sql/postgres/protocol/*`**: `impl Default` for `StartupMessage`/`SASLInitialResponse`/`PasswordMessage`/`FieldDescription`/`ReadyForQuery`. Each struct is constructed with all fields explicit at its call site(s) in `PostgresSQLConnection.rs`; `::default()` is never called and no `T: Default` bound needs them. `TransactionStatusIndicator::I` goes with them (only used by the removed `ReadyForQuery::default`). - **`runtime/valkey_jsc/index.rs`** (whole file) + `mod index` decl + `ValkeyCommand` re-export alias in `mod.rs`. Every re-export in `index.rs` was already re-exported by `mod.rs` itself; zero external imports resolve through `valkey_jsc::index::` or `::ValkeyCommand`. - **`bun_core/string/MutableString.rs`**: `index_of`, `eql`. - **`s3_signing/credentials.rs`**: a stale "DELETED" reminder comment. ## Verification For each symbol: `rg` across `src/` and `build/debug/codegen/` showed zero references outside its own definition (or only references from other removed symbols). None are `#[no_mangle]`/`extern "C"`/`#[export_name]`, none are named by string in `.classes.ts` or `src/codegen/*.ts`, none are trait impls required by a live trait bound. `bun bd` and `bun run rust:check-all` (all 10 targets including windows x64/aarch64, macOS, musl, freebsd, android) pass. Smoke tests pass for `text-decoder.test.js`, `url.test.ts`, node assert, `util-inspect.test.js`, `node-http.test.ts` (the one proxy failure there also reproduces on the system bun), node stream, and cluster. `test/internal/source-lints/dead-symbols-text-encoding-domurl.test.ts` guards against reintroduction. --- **[review]** gate passed · iteration 7 · 31 files touched

Net **-1377 LOC** (+70/-1447). Verified by `rg` across `src/` and `build/debug/codegen/` and a successful `bun bd` debug build; `test/js/web/fetch/headers.test.ts` passes. ### C++ whole-file deletions - **`RFC7230.cpp`/`RFC7230.h`** (239 LOC): global-namespace duplicate of `WebCore::RFC7230` in `HTTPHeaderField.cpp`. `HTTPParsers.cpp` includes `HTTPHeaderField.h` and resolves `RFC7230::isTokenCharacter` to the `WebCore::RFC7230` copy, so the `::RFC7230` copy was compiled but never linked against. - **`CommonAtomStrings.cpp`/`CommonAtomStrings.h`** (128 LOC): `initializeCommonAtomStrings()` is never called and none of the generated atoms (`noneAtom`, `autoAtom`, `textPlainContentTypeAtom`, ...) are referenced. - **`DOMPromiseProxy.h`** (370 LOC): only `#include`d vestigially by `JSSubtleCrypto.cpp` with no instantiation of `DOMPromiseProxy<>`, `DOMPromiseProxyWithResolveCallback`, or `IDLDOMPromiseProxy` anywhere. - **`ServerTiming.cpp`** (41 LOC): contained only `ServerTiming::isolatedCopy`, whose sole caller was `ResourceTiming::isolatedCopy` (also removed here). ### C++ members removed - **`HTTPHeaderField.h`/`.cpp`**: `class HTTPHeaderField` + `create()` and every `WebCore::RFC7230` helper it transitively used (`isDelimiter`, `isWhitespace`, `isVisibleCharacter`, `isInRange`, `isOBSText`, `isQuotedTextCharacter`, `isQuotedPairSecondOctet`, `isCommentText`, `isValidName`, `isValidValue`, the SIMD nibble tables, `vectorIsAllTokenCharacters`, `containsOnlyTokenCharacters`). Only `isTokenCharacter` (both overloads) is kept; it's the only export `HTTPParsers.cpp` actually uses. - **`NetworkLoadMetrics.h`/`.cpp`**: parameterized ctor, `updateFromFinalMetrics`, `emptyMetrics`, `isolatedCopy`; `AdditionalNetworkLoadMetricsForWebInspector` parameterized `create()`/ctor and `isolatedCopy`. All uncalled. - **`ResourceTiming.h`/`.cpp`**: `isolatedCopy` (both ref-qualifications), its private 4-arg ctor, and the commented-out `fromMemoryCache`/`fromLoad`/`fromSynchronousLoad`/`updateExposure` stubs. - **`ServerTiming.h`**: `isolatedCopy` declarations. - **`HTTPHeaderMap.h`/`.cpp`**: `isolatedCopy` (both), the `#if USE(CF)` `set(CFStringRef)` overload, `addIfNotPresent`, and the `CommonHeader`/`UncommonHeader`/`HTTPHeaderMap` `encode<>`/`decode<>` templates. None instantiated. - **`FetchHeaders.h`/`.cpp`**: `filterAndFill`: declared + defined, zero callers. ### Rust - **`install::dependency::VersionExt::is_less_than`** (trait decl + impl for `Version`): zero callers; only `is_less_than_with_tag` is used (by the Yarn lock printer). `Dependency::is_less_than` is an unrelated function on a different type. ### Verification - `rg` each removed symbol across `src/`, `build/debug/codegen/`, and `src/codegen/`: zero references outside own definition/decl pair. - `bun bd` succeeds. - `bun bd test test/js/web/fetch/headers.test.ts`: 99 pass. - `bun bd test test/js/bun/http/serve.test.ts`: 280 pass; the 4 failures (`requestIP v6`, root-range port, `#6583`, loopback `/bun:info`) reproduce identically on `main` in this environment. - `test/internal/source-lints/dead-symbols-webcore-timing-semver.test.ts` added to guard against reintroduction. ### Follow-ups (not in this diff) - `AdditionalNetworkLoadMetricsForWebInspector` and the `RefPtr<>` field on `NetworkLoadMetrics` are never populated (nothing assigns a non-null value). Removing them would cascade into `NetworkLoadPriority` and the `HTTPHeaderMap.h` include; left for a separate pass. - `HTTPHeaderMap::append(const String&, const String&)` appears to have zero callers (`FetchHeaders::append` does not route through it) but left in place pending a more careful audit. --- **[review]** gate passed · iteration 1 · 20 files touched

charset=UTF-8 Content-Transfer-Encoding: 8bit ## What `request-cyclic-reference.test.ts` and `response-cyclic-reference.test.ts` were flaky on Windows 11 aarch64 (build 86911) with: ``` expect(received).toBeLessThanOrEqual(expected) Expected: <= 100 Received: 109 ``` They pass when run alone; they only fail in the CI parallel batch. `request-clone-leak.test.ts` was flaking the same way on debian x64-asan and both Windows lanes (RSS delta 78MB vs the 64MB ASAN threshold). ## Why `bun test --parallel --isolate` runs several test files per worker process against the same JSC VM. `--isolate` swaps the `JSGlobalObject` per file and `gcUnprotect()`s the old one, but a stale pointer to the just-swapped global sits on the runner loop's stack, and JSC's conservative root scanner pins it through the next file. The four `objectTypeCounts` tests asserted on an **absolute** VM-wide count, so streams from the previous file in the worker counted against the threshold. Repro on any platform: ``` # holder.test.ts holds 120 ReadableStreams in a module-level const $ bun test --parallel=1 --isolate holder.test.ts test/js/web/fetch/response-cyclic-reference.test.ts ... Expected: <= 100 Received: 124 ``` `request-clone-leak.test.ts` is RSS-based and already uses a delta, but RSS reflects process-wide allocator state: the step-1 `Bun.gc(true)` frees the previous file's global into ASAN quarantine right before the baseline read, and the async `Bun.gc()` in the inner loop falls behind on a larger JSC heap, so peak RSS overshoots. The Windows-aarch64-only appearance is scheduling luck: workers pull files from a shared queue, so which file precedes these in a given worker depends on timing. ## Fix - `{request,response,fetch}-cyclic-reference.test.ts`, `server-response-stream-leak.test.ts`: take a baseline count before the loop and assert on the delta (matches `fetch-stream-cancel-leak.test.ts` etc). Verified all four pass with a 120-stream polluter in front under `--parallel=1 --isolate`. - `request-cyclic-reference.test.ts`: scale to 2000 iterations under ASAN (the second test was already overrunning the 5s default under debug+ASAN on main at 10000). - `request-clone-leak.test.ts`: added to `parallel-allowlist.json` `excludeFiles` so it runs solo, matching the existing entries for `fs-leak`, `fetch-leak`, `streams-leak`, `html-rewriter-leak`, `express-memory-leak`, `node-tls-getpeercert-leak`. Swept the rest of `test/`: every other `objectTypeCounts` check in a parallel-allowlisted directory already uses baseline/delta or runs in a spawned subprocess. --- **[stamp-90s]** gate passed · iteration 3 · 5 files touched

`(true, true, *)` was representable but meaningless. Every consumer already treated them as exclusive (e.g. `can_try_h3_alt_svc` checks `force_http1 || force_http2` to reject both at once; `start_` branches on one at a time). This replaces all three with a single field reusing the existing `Protocol` enum: ```rust pub forced_protocol: Option, // None | Some(Http1_1 | Http2 | Http3) ``` `None` means protocol selection is left to ALPN and the experimental flags. The same field is threaded through `FetchOptions` and the `fetch.rs` option parser. ## Why Type-system hardening: the invalid state is no longer representable. Net -9 lines. The one internal write site (`resolve_pending_h2`'s H1 arm, which previously set `force_http1 = true` on a waiter) now cannot accidentally leave a second force flag set. ## Verification No behavior change by construction. Existing coverage exercises every read/write site: ``` test/js/web/fetch/fetch-http2-client.test.ts 62 pass 0 fail test/js/web/fetch/fetch-http3-client.test.ts 53 pass 0 fail ``` including `protocol:"http2"` forcing h2, `protocol:"http1.1"` overriding the env flag, `protocol:"http2"` on `http://` failing with `HTTP2Unsupported`, `protocol:"http3"` on `http://` failing with `HTTP3Unsupported`, the Alt-Svc upgrade path, and the h2 coalesce/waiter resolution path. `cargo check -p bun_http` and `cargo clippy -p bun_http` are clean. This is a pure refactor with no observable behavior change, so a fail-before test is not applicable: any new test that exercises the `protocol:` option passes identically on main. --------- Co-authored-by: Jarred Sumner --- src/http/lib.rs | 61 ++++++++++------------- src/runtime/webcore/fetch.rs | 14 ++---- src/runtime/webcore/fetch/FetchTasklet.rs | 12 ++--- 3 files changed, 35 insertions(+), 52 deletions(-) diff --git a/src/http/lib.rs b/src/http/lib.rs index a82d14ae9c22..db163a789b26 100644 --- a/src/http/lib.rs +++ b/src/http/lib.rs @@ -207,17 +207,7 @@ pub struct Flags { pub(crate) defer_fail_until_connecting_is_complete: bool, pub(crate) upgrade_state: HTTPUpgradeState, pub(crate) protocol: Protocol, - /// Set by `fetch(url, { protocol: "http2" })`: ALPN advertises only h2 - /// and the request fails if the server selects anything else. - pub force_http2: bool, - /// Set by `fetch(url, { protocol: "http1.1" })`: opt out of h2 even when - /// the experimental env flag would otherwise advertise it. - pub force_http1: bool, - /// Set by `fetch(url, { protocol: "http3" })`: skip TCP entirely and open - /// a QUIC connection.

The same two-bool pair was threaded through `do_resolve_with_args`, `find_path_inner`, `LoaderHooks::resolve` and `resolve_hook`, with the fold above open-coded at four separate sites. This replaces the pair with a three-variant enum on the Rust side of the call chain: ```rust pub enum ResolveMode { Esm, Require, RequireResolve } ``` and folds once at each FFI entry point via `ResolveMode::from_ffi_bools`. Call sites now read `ResolveMode::RequireResolve` instead of `false, true`. ## Why Makes the nonsensical `(true, true)` state unrepresentable inside Rust, removes four copies of the same mapping, and makes call sites self-documenting. `bun_ast::ImportKind` was considered but has 12 variants, nine of which are invalid here. ## Scope Rust-internal only. The C++ FFI boundary (`Bun__resolveSync`, `Bun__resolveSyncWithPaths`, `Bun__resolveSyncWithSource` in `ImportMetaObject.h`) keeps its two-bool ABI unchanged; conversion happens once per entry point. `_resolve` still receives `is_esm` as a plain bool, so the underlying resolver continues to see only `Stmt`/`Require`, never `RequireResolve`, exactly as before (this matters for the `prefer_module_field && kind != Require` branch at `resolver.rs:5545`). ## Verification No behavior change; verified against the existing resolve suite: ``` bun bd test test/js/bun/resolve/resolve.test.ts \ test/js/bun/resolve/import-meta.test.js \ test/js/bun/resolve/require.test.ts \ test/js/bun/resolve/import-meta-resolve.test.mjs \ test/js/bun/resolve/resolve-error.test.ts # 127 pass, 0 fail bun bd test test/js/node/module/ test/js/bun/resolve/import-custom-condition.test.ts # 99 pass, 0 fail ``` This is a type-system refactor with no JS-observable difference, so there is no fail-before test to write; correctness is established by the existing coverage staying green. --- src/jsc/JSGlobalObject.rs | 9 ++++- src/jsc/ModuleLoader.rs | 7 ++-- src/jsc/NodeModuleModule.rs | 3 +- src/jsc/VirtualMachine.rs | 75 ++++++++++++++++++++++++------------ src/runtime/api/BunObject.rs | 58 ++++++++++++++++------------ src/runtime/jsc_hooks.rs | 29 ++++---------- 6 files changed, 103 insertions(+), 78 deletions(-) diff --git a/src/jsc/JSGlobalObject.rs b/src/jsc/JSGlobalObject.rs index 94d19802bcbb..8760daf7abbc 100644 --- a/src/jsc/JSGlobalObject.rs +++ b/src/jsc/JSGlobalObject.rs @@ -1479,7 +1479,14 @@ unsafe extern "C" fn Zig__GlobalObject__resolve( let (global, specifier, source) = unsafe { (&*global, *specifier, *source) };

Both construct a fresh `S::Local` via struct literal + `Default`, so a single local is never both. Folded into: ```rust pub enum LocalOrigin { Normal, TsImportEquals, CommonJsExport } ``` `can_merge_with` continues to compare only the commonjs-export bit (`origin.is_commonjs_export()`) to keep merging of `TsImportEquals` with `Normal` locals unchanged. ### `ResultFlags` external kind Every site that sets `IS_EXTERNAL_AND_REWRITE_IMPORT_PATH` does so with the same value it just wrote to `IS_EXTERNAL` (resolver.rs browser/alias remap paths), and the only reader checks it inside `if is_external()`. Replaced the pair of setters with a single `set_external_kind(ExternalKind)`; storage stays packed in the existing `ResultFlags: u8`. ```rust pub enum ExternalKind { NotExternal, External, ExternalRewritePath } ``` ### `BakeExtra` route kind `generateChunksInParallel` only assigns `fully_static` inside the `is_route = true` branch, and `is_route` itself is never read anywhere. Folded into: ```rust pub enum BakeRouteKind { NotRoute, Route, FullyStaticRoute } ``` ### Why Each pair of bools encodes four states where only three are reachable. The enum makes the invariant structural instead of incidental, so future call sites cannot produce the nonsensical combination (`rewrite && !external`, `fully_static && !is_route`, both origin bits set). For `BakeExtra` this also drops the write-only `is_route` field. ### Verification No behavior change. Verified against existing coverage: - `test/bundler/bundler_cjs2esm.test.ts` (commonjs-export rewrite path) - `test/bundler/esbuild/ts.test.ts` (TS import-equals) - `test/bundler/esbuild/packagejson.test.ts`, `test/bundler/bundler_browser.test.ts` (browser remap / external rewrite) - `test/bundler/bundler_edgecase.test.ts` - `test/bake/dev-and-prod.test.ts`, `test/bake/framework-router.test.ts` This is a type-narrowing refactor; there is no input that behaves differently before vs. after, so no new regression test is included. --- src/ast/s.rs | 32 +++++++++++---- src/bundler/OutputFile.rs | 19 ++++++++- src/bundler/bundle_v2.rs | 3 +- .../linker_context/convertStmtsForChunk.rs | 2 +- .../generateChunksInParallel.rs | 12 ++++-- .../generateCodeForFileInChunkJS.rs | 3 +- src/js_parser/p.rs | 4 +- src/js_parser/parse/parse_entry.rs | 3 +- src/js_parser/parse/parse_typescript.rs | 5 +-- src/js_parser/scan/scan_imports.rs | 2 +- src/js_parser/visit/mod.rs | 2 +- src/js_parser/visit/visit_stmt.rs | 3 +- src/resolver/lib.rs | 5 ++- src/resolver/resolver.rs | 30 ++++++++------ src/resolver/result.rs | 41 ++++++++++++++----- src/runtime/bake/production.rs | 3 +- 16 files changed, 116 insertions(+), 53 deletions(-) diff --git a/src/ast/s.rs b/src/ast/s.rs index 247898d67059..4a4223adb007 100644 --- a/src/ast/s.rs +++ b/src/ast/s.rs @@ -241,11 +241,7 @@ pub struct Local { pub kind: Kind, // = Kind::KVar pub decls: G::DeclList, // = .{} pub is_export: bool, // = false - /// The TypeScript compiler doesn't generate code for "import foo = bar" - /// statements where the import is never used. - pub was_ts_import_equals: bool, // = false - - pub was_commonjs_export: bool, // = false + pub origin: LocalOrigin, } impl Default for Local { @@ -254,8 +250,7 @@ impl Default for Local { kind: Kind::default(), decls: bun_alloc::AstAlloc::vec(), is_export: false, - was_ts_import_equals: false, - was_commonjs_export: false, + origin: LocalOrigin::Normal, } } } @@ -271,7 +266,28 @@ impl Local { } self.kind == other.kind && self.is_export == other.is_export - && self.was_commonjs_export == other.was_commonjs_export + && self.origin.is_commonjs_export() == other.origin.is_commonjs_export() + } +} + +#[derive(Clone, Copy, PartialEq, Eq, Default)] +pub enum LocalOrigin { + #[default] + Normal, + /// From TS `import x = ...`;

if `ok` is true, the equality is stored in `equal`". So `{ok: false, equal: true}` was representable but meaningless, as was `{ok: false, is_require_main_and_module: true}`. All four consumers in `src/js_parser/visit/visit_binary.rs` guarded on `ok` before reading the other two, and the `TRUE`/`FALSE`/`UNKNOWN` constants already spelled out an enum. Replaced with: ```rust pub enum Equality { Unknown, Equal, NotEqual, RequireMainAndModule, } ``` plus `From` for the known-result arms. `Data::eql` now builds variants directly and the `BinLooseEq`/`BinStrictEq`/`BinLooseNe`/`BinStrictNe` arms in `visit_binary.rs` pattern-match exhaustively. ## Why Type-level cleanup: makes the invalid states unrepresentable, drops the `..Default::default()` ceremony at every return, and makes the consumer sites an exhaustive `match` instead of nested `if`s. Net -86 lines across the two files. No behavior change. ## Verification Existing coverage; all passing with `bun bd test`: - `test/bundler/transpiler_constant_fold_eqeq.test.ts` - `test/bundler/bundler_edgecase.test.ts -t ImportMetaMain` (the `RequireMainAndModule` path) - `test/bundler/bundler_minify.test.ts` (incl. `RequireMainToImportMetaMain`) - `test/bundler/bundler_string.test.ts` - `test/bundler/bundler_cjs2esm.test.ts` - `test/bundler/esbuild/dce.test.ts` There is no new test because there is no behavior to distinguish: every return site maps one-to-one from the old `{ok, equal, is_require_main_and_module}` tuple to a variant, and the consumers are equivalent by case analysis. --- src/ast/expr.rs | 188 ++++++++++------------------ src/js_parser/visit/visit_binary.rs | 64 +++------- 2 files changed, 83 insertions(+), 169 deletions(-) diff --git a/src/ast/expr.rs b/src/ast/expr.rs index 1bcfb0ae7747..efebcbe53272 100644 --- a/src/ast/expr.rs +++ b/src/ast/expr.rs @@ -2667,36 +2667,26 @@ impl Data { // Equality // ─────────────────────────────────────────────────────────────────────────── -#[derive(Clone, Copy, Default)] -pub struct Equality { - pub equal: bool, - pub ok: bool, - - /// This extra flag is unfortunately required for the case of visiting the expression - /// `require.main === module` (and any combination of !==, ==, !=, either ordering) - /// - /// We want to replace this with the dedicated import_meta_main node, which: - /// - Stops this module from having p.require_ref, allowing conversion to ESM - /// - Allows us to inline `import.meta.main`'s value, if it is known (bun build --compile) - pub is_require_main_and_module: bool, +#[derive(Clone, Copy)] +pub enum Equality { + /// Nothing is known about the equality of the two operands. + Unknown, + Equal, + NotEqual, + /// `require.main === module` (or `!==`/`==`/`!=`, in either order); the + /// caller rewrites this to an import_meta_main node. + RequireMainAndModule, } -impl Equality { - pub(crate) const TRUE: Equality = Equality { - ok: true, - equal: true, - is_require_main_and_module: false, - }; - pub(crate) const FALSE: Equality = Equality { - ok: true, - equal: false, - is_require_main_and_module: false, - }; - pub(crate) const UNKNOWN: Equality = Equality { - ok: false, - equal: false, - is_require_main_and_module: false, - }; +impl From for Equality { + #[inline] + fn from(equal: bool) -> Self { + if equal { + Equality::Equal + } else { + Equality::NotEqual + } + } } // `adt_const_params` (enum const-generic) is nightly-only.

Every consumer treats them as a three-way switch. Replaced with `enum StatementScope { Nested, Module, Namespace }`. The seven copies of ```rust if !opts.is_module_scope && (!opts.is_namespace_scope || !opts.is_typescript_declare) ``` fold into `if !opts.allows_esm_import_export()`, and the `if/else if` at the top of `t_export` becomes an exhaustive `match`. ## `scan_side_effects::Result` `Result { ok, value, side_effects }` only carries a meaningful `value` / `side_effects` when `ok == true`; every caller guards on `.ok` before reading either field. `{ ok: false, value: true }` was never constructed. Replaced with `Option` so `to_boolean` and `to_null_or_undefined` return `None` for the unknown case and callers use `if let Some(..)` / `is_some_and(..)` instead of a separate `.ok` read. ## Why Making both states unrepresentable removes the possibility of a future change constructing `{ is_module_scope: true, is_namespace_scope: true }` or reading `.value` without checking `.ok`, both of which would silently miscompile. No behavior change. ## Verification This is a type-level refactor with no semantic change, so there is no test that fails before and passes after. Existing coverage exercises every touched path and passes unchanged: - `test/bundler/esbuild/dce.test.ts` (78 pass) - `test/bundler/esbuild/ts.test.ts` (57 pass) - `test/bundler/esbuild/default.test.ts` (151 pass) - `test/bundler/esbuild/importstar_ts.test.ts` (23 pass) - `test/bundler/bundler_minify.test.ts` (42 pass) - `test/bundler/bundler_edgecase.test.ts` (117 pass) - `test/bundler/bundler_regressions.test.ts` (9 pass, incl.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## What Two groups of mutually-exclusive bools on the install CLI types become the enums they already fold into: ### `Update{development,optional,peer}` → `DependencyGroup` `struct Update` on `Options` was three bools, at most one ever set (via an `if/else if` cascade), consumed by an identical cascade in `updatePackageJSONAndInstall` to pick one of `dependencies` / `devDependencies` / `optionalDependencies` / `peerDependencies`. `bun_install_types::DependencyGroup` already exists with exactly these four constants and a `.prop` field carrying the package.json key. The struct is removed, the field becomes `DependencyGroup`, and the consumer cascade becomes a single `.prop` read. ### `silent` / `quiet` / `verbose` → `LogLevel` `CommandLineArguments` carried three separate bools that `Options::load` folded into `LogLevel` via a four-branch cascade. The CLI now stores `log_level: LogLevel` directly; `Options::load` just folds in the no-progress bit via the new `LogLevel::without_progress()`. `--silent` is checked first in the precedence, so `LogLevel::is_silent()` is true exactly when `--silent` was passed. The four callers that previously read `cli.silent` to suppress summaries/errors (`Options::load`, `bun outdated`, `bun publish`, `bun update -i`) are routed through `is_silent()` and behave identically. ## Why Making illegal states unrepresentable: `Update{development:true, peer:true}` was constructible but meaningless, and there were two parallel encodings of the same four-way choice (`Update` vs `DependencyGroup`). Net -16 lines with the cascades gone. The `LogLevel` change has one observable effect: previously `Output::is_verbose()` (set by `RUNNER_DEBUG=1` in GitHub Actions) would win over an explicit `--silent` for the log level, so `RUNNER_DEBUG=1 bun install --silent` leaked verbose lockfile diagnostics to stderr: ``` Clean lockfile: 1 packages - 1 packages in 11.8us No packages! Deleted empty lockfile ``` while still suppressing the summary. With `--silent` checked first it is now fully silent, which is what `--silent` promises. ## Verification - New test: `RUNNER_DEBUG=1 bun install --silent` produces no output (fails on main, passes here). - `bun-add.test.ts` (54 tests, covers `--dev`/`--optional`/`--peer`) and `bun-pack.test.ts` (76 tests, covers `--silent`) pass unchanged. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Previously the two independent bools let editor mode stack on top of multiline; with a single mode enum that stacking is not representable, and silently entering editor mode here would either abandon the pending input or leave a stale buffer. Ignoring the command keeps the user at the continuation prompt with nothing lost. The `Renameat2Flags` refactor is behavior-preserving; no caller ever set both bools. ## Verification - `bun bd test test/js/bun/shell/commands/ls.test.ts` (new `-a/-A` ordering tests; 27 pass, 2 pre-existing root-only failures) - `bun bd test test/js/bun/repl/repl.test.ts` (148 pass, including the new `.editor`-from-multiline test) - `cargo test -p bun_sys` (15 pass, including `renameat_concurrently_does_not_close_caller_fd`) - `bun run rust:check-all` (10/10 targets) --- src/install/npm.rs | 2 +- src/runtime/cli/repl.rs | 112 +++++++++++++++----------- src/runtime/shell/builtin/ls.rs | 36 ++++----- src/sys/lib.rs | 46 ++++++----- test/js/bun/repl/repl.test.ts | 16 ++++ test/js/bun/shell/commands/ls.test.ts | 30 +++++++ 6 files changed, 156 insertions(+), 86 deletions(-) diff --git a/src/install/npm.rs b/src/install/npm.rs index b164f015247e..7c1b77b4a08d 100644 --- a/src/install/npm.rs +++ b/src/install/npm.rs @@ -1217,7 +1217,7 @@ pub mod package_manifest { cache_dir, outpath, bun_sys::Renameat2Flags { - exchange: true, + mode: bun_sys::RenameMode::Exchange, ..Default::default() }, )?; diff --git a/src/runtime/cli/repl.rs b/src/runtime/cli/repl.rs index 092dfa56f880..d9e9fbbc54fb 100644 --- a/src/runtime/cli/repl.rs +++ b/src/runtime/cli/repl.rs @@ -781,12 +781,15 @@ fn cmd_save(repl: &mut Repl, args: &[u8]) -> ReplResult { } fn cmd_editor(repl: &mut Repl, _: &[u8]) -> ReplResult { + if repl.input_mode == InputMode::Multiline { + return ReplResult::SkipEval; + } repl.print(format_args!( "{}// Entering editor mode (Ctrl+D to finish, Ctrl+C to cancel){}\n", Color::DIM, Color::RESET )); - repl.editor_mode = true; + repl.input_mode = InputMode::Editor; repl.editor_buffer.clear(); ReplResult::SkipEval } @@ -794,7 +797,7 @@ fn cmd_editor(repl: &mut Repl, _: &[u8]) -> ReplResult { fn cmd_break(repl: &mut Repl, _: &[u8]) -> ReplResult { repl.line_editor.clear(); repl.multiline_buffer.clear(); - repl.in_multiline = false; + repl.input_mode = InputMode::Normal; ReplResult::SkipEval } @@ -827,6 +830,13 @@ fn cmd_history(repl: &mut Repl, _: &[u8]) -> ReplResult { // Main REPL Struct // ============================================================================ +#[derive(Clone, Copy, PartialEq, Eq)] +enum InputMode { + Normal, + Multiline, + Editor, +} + pub(super) struct Repl<'a> { line_editor: LineEditor, history: History, @@ -834,8 +844,7 @@ pub(super) struct Repl<'a> { editor_buffer: Vec, // State - in_multiline: bool, - editor_mode: bool, + input_mode: InputMode, running: bool, is_tty: bool, use_colors: bool, @@ -873,8 +882,7 @@ impl<'a> Repl<'a> { history: History::init(), multiline_buffer: Vec::new(), editor_buffer: Vec::new(), - in_multiline: false, - editor_mode: false, + input_mode: InputMode::Normal, running: false, is_tty: false, use_colors: false, @@ -1170,7 +1178,7 @@ impl<'a> Repl<'a> { // ======================================================================== fn get_prompt(&self) -> &'static [u8] { - if self.in_multiline || self.editor_mode { + if self.input_mode != InputMode::Normal { if self.use_colors { return concat!("\x1b[2m", "...

No behavior change. ## `install_preference: OfflineMode` `BundleOptions` (both the bundler and resolver copies) carried `prefer_offline_install: bool` plus, on the bundler side, `prefer_latest_install: bool`. Every write site (`run_command.rs`, `repl_command.rs`, `bake/production.rs`) derived both from a single `OfflineMode` value: ```rust b.options.prefer_offline_install = offline == OfflineMode::Offline; b.options.prefer_latest_install = offline == OfflineMode::Latest; ``` `prefer_latest_install` was write-only: nothing in the tree reads it. `(true, true)` would have been contradictory but the type allowed it. Now both structs store `install_preference: OfflineMode` directly. The one reader (resolver auto-install disk-cache lookup) checks `== OfflineMode::Offline`. The three write sites each drop ~10 lines of enum-to-bool decoding plus the comments explaining why the resolver lacked `prefer_latest_install`. ## `compile_mode: CompileMode` `BundleOptions` and `LinkerOptions` each carried `compile: bool` and `compile_to_standalone_html: bool`. The two are mutually exclusive by construction: both `build_command.rs` and `js_bundle_completion_task.rs` explicitly clear `compile` when they set `compile_to_standalone_html`: ```rust this_transpiler.options.compile_to_standalone_html = true; this_transpiler.options.compile = false; ``` Now both structs store: ```rust pub enum CompileMode { None, Executable, StandaloneHtml } ``` with `is_executable()` / `is_standalone_html()` helpers. The `(true, true)` state is no longer representable. The resolver's `BundleOptions.compile: bool` projection is kept as-is (resolver never cares about standalone HTML) and is fed `compile_mode.is_executable()`. The CLI-level `ctx.bundler_options.compile: bool` is unchanged: that is the raw `--compile` flag before HTML/browser detection decides which mode it becomes. ## Why Making illegal states unrepresentable removes a class of drift bugs where one bool gets updated and the other doesn't, and it deletes the cross-file comments that existed only to explain which struct had which subset of the bools. `prefer_latest_install` was already dead; this removes it rather than leaving it to bit-rot. ## Verification No behavior change; verified against existing coverage: - `test/bundler/bundler_compile.test.ts` (60 pass, 1 pre-existing fail on main: `HelloWorldWithProcessVersionsBun`) - `test/bundler/standalone.test.ts` (23 pass; covers `CompileMode::StandaloneHtml` via both CLI and `Bun.build`) - `test/bundler/bundler_html.test.ts` (22 pass) - `test/bundler/bun-build-api.test.ts` (49 pass) - `test/bundler/cli.test.ts` (16 pass) - `test/bundler/bun-build-compile.test.ts` (11 pass, 1 pre-existing timeout on main: `compile with relative outfile paths`) Net -1 line across 18 files. --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Jarred Sumner --- src/bundler/HTMLImportManifest.rs | 2 +- src/bundler/LinkerContext.rs | 8 ++-- src/bundler/ParseTask.rs | 6 +-- src/bundler/bundle_v2.rs | 11 +++--- .../linker_context/OutputFileListBuilder.rs | 4 +- .../generateChunksInParallel.rs | 12 +++--- .../generateCompileResultForHtmlChunk.rs | 2 +- .../linker_context/postProcessJSChunk.rs | 2 +- src/bundler/options.rs | 39 +++++++++++++------ src/bundler/transpiler.rs | 4 +- src/options_types/offline_mode.rs | 3 +- src/resolver/options.rs | 4 +- src/resolver/resolver.rs | 2 +- src/runtime/api/js_bundle_completion_task.rs | 14 ++++--- src/runtime/bake/production.rs | 18 ++------- src/runtime/cli/build_command.rs | 9 +++-- src/runtime/cli/repl_command.rs | 17 ++------ src/runtime/cli/run_command.rs | 7 +--- 18 files changed, 82 insertions(+), 82 deletions(-) diff --git a/src/bundler/HTMLImportManifest.rs b/src/bundler/HTMLImportManifest.rs index 5d3a551cbcc0..3b8e54eed82d 100644 --- a/src/bundler/HTMLImportManifest.rs +++ b/src/bundler/HTMLImportManifest.rs @@ -193,7 +193,7 @@ pub(crate) fn write( writer.write_all(b"{")?; -

No behavior change. ### `ProcessHandle.visited` / `visiting` → `VisitState` `has_cycle()` in `src/runtime/cli/filter_run.rs` is a textbook DFS cycle check that set both flags on entry and cleared only `visiting` on exit, so `visiting && !visited` was unreachable. Replaced with: ```rust enum VisitState { Unvisited, Visiting, Visited } ``` and an exhaustive `match` in `has_cycle`. ### `GitResult.ok` / `spawn_failed` → tri-variant enum In `src/runtime/cli/test/ChangedFilesFilter.rs`, every `run_git` constructor produced exactly one of `{spawn_failed, !ok, ok}`; `ok && spawn_failed` was impossible and every caller checked `spawn_failed` first, then `ok`. Replaced with: ```rust enum GitResult { SpawnFailed, ExitError { stderr: Vec }, Ok { stdout: Vec }, } ``` Each variant now carries only the output stream the caller actually reads on that path (stderr on error, stdout on success), and call sites became exhaustive matches. Net -9 lines. ### Verification - `test/cli/run/filter-workspace.test.ts`: 56 pass (incl. `ignore dependency order on cycle`, `detect cycle of length > 2`, `respect dependency order`) - `test/cli/test/test-changed.test.ts`: 20 pass (incl. `errors helpfully outside a git repo`, `--changed=` paths, subdirectory/untracked paths) There is no new test because there is no behavior to distinguish: each `run_git` call site maps one-to-one from the old `{ok, spawn_failed}` pair to a variant (spawn failure, nonzero exit, success), and `has_cycle` performs the same DFS with the same detection condition (back-edge to a node on the current stack). The suites above exercise every touched path, matching the approach taken in #36762. --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Jarred Sumner --- src/runtime/cli/filter_run.rs | 30 ++-- src/runtime/cli/test/ChangedFilesFilter.rs | 186 ++++++++++----------- 2 files changed, 103 insertions(+), 113 deletions(-) diff --git a/src/runtime/cli/filter_run.rs b/src/runtime/cli/filter_run.rs index 73fffdea20d5..0c1b58a5fd62 100644 --- a/src/runtime/cli/filter_run.rs +++ b/src/runtime/cli/filter_run.rs @@ -66,8 +66,14 @@ pub(crate) struct ProcessHandle<'a> { remaining_dependencies: usize, dependents: Vec<*mut ProcessHandle<'a>>, - visited: bool, - visiting: bool, + visit_state: VisitState, +} + +#[derive(Clone, Copy)] +enum VisitState { + Unvisited, + Visiting, + Visited, } impl<'a> ProcessHandle<'a> { @@ -978,8 +984,7 @@ pub(crate) fn run_scripts_with_filter( end_time: None, remaining_dependencies: 0, dependents: Vec::new(), - visited: false, - visiting: false, + visit_state: VisitState::Unvisited, });

When the first lookup fills the slot as cacheable and the second lookup reaches `setGetterSlot`/`setCustom`/`setValue(JSObject*,unsigned,JSValue)`, those overloads assert the slot is still `CachingDisallowed`, and a debug/ASAN build aborts. ## Repro ``` ASSERTION FAILED: m_cacheability == CachingDisallowed vendor/WebKit/Source/JavaScriptCore/runtime/PropertySlot.h : void JSC::PropertySlot::setGetterSlot(JSObject *, unsigned int, GetterSetter *) ``` Minimal trigger (Node passes this): ```js const vm = require("node:vm"); const sandbox = {}; for (let i = 0; i < 200; i++) { sandbox["k" + i] = i; delete sandbox["k" + i]; } // uncacheable dictionary Object.defineProperty(sandbox, "Array", { get: () => Array, configurable: true }); vm.createContext(sandbox); vm.runInContext( 'Object.defineProperty(this, "Array", { value: 1, configurable: true, writable: true }); Array', sandbox, ); ``` Real-world: `jest` under `bun --bun` with `testEnvironment: "node"`. `jest-environment-node` copies enough globals onto the sandbox to push it to an uncacheable dictionary and installs lazy-init getters that call `Object.defineProperty(this, name, { value })` on first access. ## Why Backtrace from the jest run (llvm-addr2line on a walked `rbp` chain at `WTFReportAssertionFailure`): ``` PropertySlot::setGetterSlot PropertySlot.h:328 JSObject::fillGetterPropertySlot JSObject.cpp:2972 JSObject::getOwnNonIndexPropertySlot JSObject.h:1117 JSObject::getPropertySlot JSObject.h:1197 NodeVMGlobalObject::defineOwnProperty NodeVM.cpp (contextifiedObject->getPropertySlot) JSGlobalProxy::defineOwnProperty objectConstructorDefineProperty ... JS getter re-entry via PropertySlot::functionGetter ... NodeVMGlobalObject::getOwnPropertySlot NodeVM.cpp (slot.getValue) JSGlobalProxy::getOwnPropertySlot llint_slow_path_get_by_val ``` Inside `defineOwnProperty`: 1. `globalObject->JSC::JSGlobalObject::getOwnPropertySlot(..., slot)` finds `Array` as a lazy `CustomGetterSetter` on a non-dictionary structure, so `fillCustomGetterPropertySlot` calls `setCacheableCustom`, which sets `m_cacheability = CachingAllowed`. 2. `contextifiedObject->getPropertySlot(..., slot)` walks the sandbox. The sandbox is now an uncacheable dictionary holding an accessor for the same name, so `fillGetterPropertySlot` takes the uncacheable branch and calls `setGetterSlot`, which asserts `m_cacheability == CachingDisallowed`. Release builds don't see this because `ASSERT` compiles out, but the invariant is still violated: the cached offset/structure left in the slot describes the global object, not the sandbox. ## Fix Use a fresh `PropertySlot` for the sandbox probe. Only the boolean result is consumed afterwards, so nothing else changes. This matches the pattern already used in `NodeVMGlobalObject::put` (a dedicated `getter` slot) and at the proxy-target lookup in `getOwnPropertySlot` (`target_slot`). ## Verification - New test in `test/js/node/vm/vm.test.ts` spawns the minimal repro and asserts the Node-matching `{ result: 1, sandboxArray: 1 }` output, so release lanes still exercise the path. - Gate simulation: with `src/` stashed the test fails with the `setGetterSlot` assertion; with the fix it passes. - Full `test/js/node/vm/vm.test.ts`: 213 pass / 0 fail. - jest 29.7 + ts-jest under `bun --bun` on a debug build now runs to completion. --- **[stamp-90s]** gate passed · iteration 0 · 2 files touched

In `visit_class`, when the option is `false` the TypeScript lowering block now follows esbuild: - parameter-property assignments go into the constructor as before, but the matching declaration-only class field is no longer emitted - non-static instance fields are removed from the class body; those with an initializer become `this.key = init` in the constructor, in source order, after the parameter-property assignments - private fields keep `#x;` and only have the initializer moved - decorated fields have their initializer moved here and are kept initializer-less so `lower_class` still emits the `__legacyDecorateClassTS` call - a constructor is synthesized (with `super(...arguments)` when extending) if none is declared Computed fields with a non-literal key and static fields are left as native class fields for now so the key expression is not re-evaluated per instance; neither is involved in the reported bug. `true` and unset keep the existing [[Define]] behaviour unchanged. ## Tests `test/bundler/transpiler/ts-use-define-for-class-fields.test.ts` covers the issue repro, ordering/[[Set]] semantics vs an inherited accessor, constructor synthesis, the decorated-field case, `Bun.Transpiler`, and that `true`/unset are unchanged. ``` bun bd test test/bundler/transpiler/ts-use-define-for-class-fields.test.ts # 7 pass bun bd test test/bundler/transpiler/ # 3862 pass ``` --- **[review]** gate passed · iteration 3 · 12 files touched

Setting `m_closed` makes the stated invariant hold and short-circuits that path. - **`directStreamControllerClearSource`**: moved into `Bun::WebStreams` and declared in `WebStreamsInternals.h` so `ReadableStreamOperations.cpp` can reuse it. - **`readableStreamReaderGenericRelease`**: drop the redundant `stream->m_nativePtr` gate; `kind == Native` already implies a live adapter whose `handle()` the body reads. - **`readable-stream-terminal-barrier-release.test.ts`**: collapsed into a single subprocess with one shared GC storm and no per-test timeout override (the previous per-case subprocess shape brushed the default timeout under debug+ASAN). ## Why `m_nativePtr` is left alone The first revision of this PR cleared `m_nativePtr` once the adapter owned the handle. That broke `test/js/web/fetch/fetch.stream.test.ts` "response inspected size should reflect stream state": `Bun.inspect(response)` reports the body byte count via `PendingValue::size_hint()`, which re-derives `*mut ByteStream` through `ReadableStreamTag__tagged` on every call; `FetchTasklet::on_body_received` only updates `bytes.size_hint` on the ByteStream (not the `PendingValue` fallback field), so once the slot is cleared inspect falls back to a stale first-chunk value. Adding an adapter fallback to `ReadableStreamTag__tagged` fixed the fetch-body-delivery path but not this one, because the slot is also cleared at ClearAlgorithms (when the adapter has already severed). Handing the handle off cleanly needs the Rust side to cache the final size somewhere tag-independent; left for a separate change. --- **[review]** gate passed · iteration 8 · 4 files touched

The user-visible one: a response with `Connection: close, keep-alive` was returned to the keep-alive pool, and the next request on that socket failed with *"The socket connection was closed unexpectedly"* / `ECONNRESET`. All sites now go through the existing `HeaderValueIterator` (which now `impl Iterator`). | Header | Before | After | |---|---|---| | `Connection` (fetch req + resp) | exact `close` / `keep-alive` only | any `close` token disables pooling; `close` wins over `keep-alive` | | `Connection` (WebSocket 101) | must equal `Upgrade`; only first header read | must *contain* `upgrade`, across multiple `Connection` headers | | `Transfer-Encoding` (resp) | `gzip, chunked` → `UnsupportedTransferEncoding` | chunked framing; `chunked` not-last or unknown coding rejected | | `Content-Encoding` (resp) | `identity, gzip` / `gzip, identity` not decoded | `identity` ignored; stacked codings (`gzip, br`) pass through raw with header intact | | `Upgrade` (fetch req) | case-sensitive in one of two call sites | shared, case-insensitive | Tests extend the existing matrices in `fetch-keepalive.test.ts`, `fetch-gzip.test.ts`, `websocket-client.test.ts`; the new rows fail on current canary.

Despite the name, libinfo implements this by dispatching a *blocking* `si_addrinfo` onto the libdispatch overcommit root queue ([si_module.c:1173](https://github.com/apple-oss-distributions/Libinfo/blob/main/lookup.subproj/si_module.c#L1173)): ```c dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, DISPATCH_QUEUE_OVERCOMMIT), ^{ si_async_launchpad(req); }); ``` So each distinct in-flight lookup parks one worker thread in-process. Measured on Darwin 25.5 arm64 with distinct unresolvable hostnames (to defeat same-host coalescing), threads via `ps -M`: ``` N=50 baseline threads=9 -> PEAK threads=64 N=200 baseline threads=9 -> PEAK threads=214 N=500 baseline threads=9 -> PEAK threads=513 (+26 MB RSS) N=1000 baseline threads=9 -> PEAK threads=525 ``` Linear until libdispatch's own ~512-thread ceiling; threads do not retire promptly after completion. ## Why this is the same resolver libinfo's `search_addrinfo` only consults modules that implement `sim_addrinfo`; `ds_module` (Open Directory / LDAP) sets it to NULL with the literal comment `/* host lookups not supported */` ([ds_module.c:2241-2275](https://github.com/apple-oss-distributions/Libinfo/blob/main/lookup.subproj/ds_module.c#L2241-L2275)). Only `mdns_module` (→ `DNSServiceQueryRecord` → mDNSResponder) and `file_module` (→ `/etc/hosts`) do. mDNSResponder itself watches `/etc/hosts`. So `getaddrinfo()` on macOS = mDNSResponder + /etc/hosts, and the thread wrapper is the only thing this change removes. ## Fix Talk to mDNSResponder directly via `DNSServiceGetAddrInfo` over a single `DNSServiceCreateConnection` + `kDNSServiceFlagsShareConnection` primary: **one** Unix-domain socket to the daemon, **one** kqueue knote, zero extra threads regardless of in-flight count. Both `dns.lookup()` (the `GetAddrInfoRequest` path) and the internal connect-path resolver (`internal::Request`) now go through the shared connection. Completion on a shared connection can't use `kDNSServiceFlagsMoreComing` (it's collective across all sub-refs). Instead this tracks per-family pending bits: `dnssd_clientstub` always passes a family-tagged `sockaddr` in the callback, including for `NoSuchRecord` and `Timeout` ([dnssd_clientstub.c handle_addrinfo_response](https://github.com/apple-oss-distributions/mDNSResponder/blob/main/mDNSShared/dnssd_clientstub.c)), so a query is ready once every requested family has reported in. `kDNSServiceFlagsReturnIntermediates` + `kDNSServiceFlagsTimeout` ensure each family eventually does. If mDNSResponder is unreachable (`DNSServiceCreateConnection` fails, e.g. in a sandbox), both paths fall back to the existing blocking `getaddrinfo` on the work pool. Deleted: the `lib_info` dlopen/dlsym module, `getaddrinfo_send_reply` (the mach-port reply bridge in `io_darwin.cpp`), the per-request machport `FilePoll`s. ## Test Covered by the existing DNS suites, which run through this backend on macOS: `test/js/node/dns/node-dns.test.js` (119), `test/js/bun/dns/dns-interleave.test.ts`, `test/js/node/net/node-net.test.ts` (67), `test/js/node/dgram/`. Thread behaviour was measured by hand rather than asserted in CI: 200 concurrent `dns.lookup()` of distinct `.invalid` hostnames, sampling `ps -M ` while in flight — peak ≈ baseline + 200 before, ≈ baseline after. An earlier `dns-sd-threads.test.ts` asserting this was dropped at the maintainer's request. ## Notes - `protocol` is passed as `IPv4|IPv6` explicitly (not `0`), because the completion check needs to know which families were requested. This drops the daemon's "skip family with no routable address" heuristic (the `AI_ADDRCONFIG` equivalent). The existing `BUN_FEATURE_FLAG_DISABLE_IPV4/IPV6` env vars still constrain it, and happy-eyeballs handles unreachable addresses at connect time. - `BUN_FEATURE_FLAG_DISABLE_DNS_CACHE_LIBINFO=1` still forces the work-pool fallback (name kept for compat). --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

With a file-backed database and non-strict `close()`, nothing throws but the file handle stays open until GC, which on Windows makes the database file undeletable right after closing it. ## Cause `query()` only tracks the first `MAX_QUERY_CACHE_SIZE` distinct statements; later ones are prepared but stored nowhere, so `close()` could not finalize them and `sqlite3_close()` returned `SQLITE_BUSY`. ## Fix Per review, the mechanism mirrors better-sqlite3's `CloseHandles()` and node:sqlite's `FinalizeStatements()`: - `VersionSqlite3` keeps a list of live `JSSQLStatement` wrappers, linked at creation (next to the existing `reference_count` increment) and unlinked in the destructor. - `close()` walks that list, `sqlite3_finalize`s each statement and nulls the wrapper's handle, then runs a `sqlite3_next_stmt()` sweep as a backstop for statements not owned by a wrapper (e.g. the transient statement in `db.run()` when a bound-parameter getter closes the database mid-bind), then calls `sqlite3_close()`, which can no longer return `SQLITE_BUSY`. - Because a nulled handle is indistinguishable from an explicitly finalized statement, the existing "Statement has finalized" re-validation paths cover all post-close use; no new per-statement state. The bind paths re-check the connection after running user code, and `raw()`'s push-exception path no longer resets a statement that user code may have finalized. - If `sqlite3_close()` somehow still fails, the handle is retired via `sqlite3_close_v2()` so the connection never ends up half-alive. The termination path and GC `release()` still use `sqlite3_close_v2()` without touching the list, so their outstanding statements stay valid until each is finalized, as before. Behavior change, reflected in docs and types: `close(true)` no longer throws `database is locked` over outstanding prepared statements; it finalizes them, matching better-sqlite3 and node:sqlite. Using a statement after close throws `Statement has finalized`, matching node. ## Verification Without the fix: ``` $ USE_SYSTEM_BUN=1 bun test test/js/bun/sqlite/sqlite.test.js -t 36572 (fail) close(true) finalizes query() statements created after the cache filled up (#36572) error: database is locked (fail) close(true) finalizes query() statements past the cache limit that are still referenced (#36572) ``` With the fix: `bun bd test test/js/bun/sqlite/` 115 pass, `test/js/node/sqlite/` 115 pass, `test/regression/issue/14709.test.ts` 5 pass, bun-types 14 pass.

If that setup throws (for example a direct `ReadableStream` whose `pull` getter throws), the controller is never started, so nothing ever calls `end()`/`close()` to null `m_sinkPtr`. The caller's error path (`Writable::init` for `Bun.spawn`) then releases and frees the native sink. When the controller is later swept, its destructor runs `${name}__controllerDetached` / `${name}__finalize` on freed memory. ASAN report: ``` heap-use-after-free on address 0x799feed81c78 READ of size 1 #0 JSSink::js_controller_detached Sink.rs:567 #1 FileSink__controllerDetached generated_jssink.rs:179 #2 JSReadableFileSinkController::~JSReadableFileSinkController() freed by: #12 FileSink::deinit FileSink.rs:1142 #16 Writable::pipe_release Writable.rs:70 #17 Writable::init Writable.rs:339 #18 spawn_maybe_sync js_bun_spawn_bindings.rs:1379 ``` The fix is at the generic `JSSink::assign_to_stream` layer so it covers every sink type (`FileSink`, `NetworkSink`, `FetchRequestBodySink`, ...), not just the spawn path. ## Repro ```js const { openSync, closeSync } = require("node:fs"); const fd = openSync("/tmp/out.txt", "w"); let armed = false; const stream = new ReadableStream({ type: "direct", get pull() { if (armed) throw new Error("pull unavailable"); return () => {}; }, }); armed = true; try { Bun.spawn({ cmd: [process.execPath, "-e", "0"], stdio: [stream, fd, "ignore"] }); } catch {} closeSync(fd); Bun.gc(true); // sweep -> controller dtor -> UAF ``` ## Tests The two existing `spawn.test.ts` cases that cover the stdin-stream-setup-throws path now force a full GC in the child fixture so the controller destructor runs deterministically under debug+ASAN as well. Previously they were only failing on the release-asan lane (where the whole file has been quarantined as `[ASAN] [TIMEOUT]`), which is why this went unnoticed. ``` bun bd test test/js/bun/spawn/spawn.test.ts -t "stdin stream setup fails" ``` fails on `main` (ASAN heap-use-after-free in the child's stderr) and passes with this change. `spawn-stdin-readable-stream-edge-cases.test.ts` and `body-stream.test.ts` continue to pass. --- src/runtime/webcore/Sink.rs | 16 ++++++++++++++++ test/js/bun/spawn/spawn.test.ts | 3 +++ 2 files changed, 19 insertions(+) diff --git a/src/runtime/webcore/Sink.rs b/src/runtime/webcore/Sink.rs index b7e1127eeac0..d84639a287a9 100644 --- a/src/runtime/webcore/Sink.rs +++ b/src/runtime/webcore/Sink.rs @@ -209,6 +209,22 @@ impl JSSink { std::ptr::from_mut::(ptr).cast::(), (&raw mut bits).cast::<*mut c_void>(), ); + // `${name}__assignToStream` creates the JSReadable*SinkController with + // m_sinkPtr=ptr before calling into the stream pump.

Probed in build [87834](https://buildkite.com/bun/bun/builds/87834) it passes every release and release-asan lane cleanly, so the quarantine is stale for CI. What it was hiding is a debug-only false positive: under `bun bd` the two `yes is killed` cases fail deterministically. ## Repro ``` $ bun bd test test/js/bun/spawn/spawn-maxbuf.test.ts -t "yes is killed" (fail) yes is killed > Bun.spawn error: expect(received).toBeLessThan(expected) Expected: < 100 Received: 170 (fail) yes is killed > Bun.spawnSync error: expect(received).toBeLessThan(expected) Expected: < 100 Received: 162 ``` ## Cause Both tests assert `Date.now()` from before `spawn()` to after `exited` is under 100ms, with the comment "make sure it's not waiting a full tick". The child is `[bunExe(), "exec", "yes"]`, so the measured window includes the child `bun` process reaching `main()` before `yes` can write its first byte. On a debug+ASAN build that startup alone is ~150-250ms: ``` $ bun bd -e 'const t=Date.now(); Bun.spawnSync([process.execPath,"-e",""]); console.log(Date.now()-t)' 185 ``` so the 100ms budget is exhausted before maxBuffer has anything to react to. Release and release-asan start in <15ms and stay well inside the bound. ## Fix Widen the wall-clock window to `isDebug ? 1000 : 100`, matching the pattern used elsewhere for timing budgets that include a debug-build spawn (e.g. `fetch-tls-abortsignal-timeout.test.ts`, `buffer-indexof-worstcase.test.ts`). Release keeps the original 100ms bound unchanged. Promptness of the kill itself is already asserted byte-precisely by the "caps the buffer while the child is still writing" tests (`stdout.length <= maxBuffer + 64*1024` against an 8MB firehose), so this assertion is only the coarse "not deferred by seconds" sanity check. Drop the whole-file quarantine line. ## Verification ``` $ bun bd test test/js/bun/spawn/spawn-maxbuf.test.ts 16 pass 0 fail ``` Five consecutive `bun bd` runs: `yes is killed` at 128-157ms (< 1000). Release: 2-11ms (< 100).

That is a user-visible change from v1.3.x for a producer whose in-flight `pull()` keeps calling the controller after the consumer has cancelled (or after its own `end()`/`error()`). ```js const rs = new ReadableStream({ type: "direct", async pull(c) { ctrl = c; c.write("first"); await new Promise(() => {}); }, }); const r = rs.getReader(); r.read().catch(() => {}); // ...after pull has started... await r.cancel(); ctrl.write("after-cancel"); // v1.3.x: byte count // after #36703: TypeError: ReadableStreamDirectController is now closed ``` ## Fix Keep `m_closed = true` on cancel (the state is accurate) and change the bound handlers to no-op instead of throw once `m_closed` is set: `write()` returns `0`, `end()`/`close()`/`flush()`/`error()` return `undefined`. `ReadableStreamOperations.cpp` is unchanged from main; the now-unused `directControllerClosedMessage` constant is removed. ## Verification ``` # without src/ change TypeError: ReadableStreamDirectController is now closed (fail) direct controller methods no-op once closed # with src/ change (incl.

Supersedes #36787. ## Why it was slow The suite runs under `describe.concurrent`, but every PE metadata read was a **synchronous** `execSync("powershell -Command ...")` spawned once per `VersionInfo` field. `execSync` blocks the event loop, so while one test was serially spawning its six PowerShell processes (~0.5-1s each) the other 20+ concurrent `bun build --compile` tests could not observe their subprocess completions or make any progress. Roughly 34 PowerShell startups were serialized onto the critical path. ## Why it occasionally flaked Windows PowerShell 5.1 encodes piped stdout with `[Console]::OutputEncoding`, derived from `GetConsoleOutputCP()` at startup. The console output code page is per-**console** state: another process attached to the same console can flip it off UTF-8 between Bun's startup `SetConsoleOutputCP(65001)` and the `execSync("powershell ...")`, at which point CP 437 best-fits U+00A9 `©` to ASCII `c` and the `LegalCopyright` assertion fails. ## Fix - Replace the per-field sync reads with a single async `Bun.spawn` that returns every field as JSON via `Select-Object | ConvertTo-Json`, launched with `-NoProfile -NonInteractive`. One spawn per executable instead of up to six, and it no longer blocks other concurrent tests. - Prefix the PowerShell command with `[Console]::OutputEncoding = [System.Text.Encoding]::UTF8` so the read is independent of per-console code page state. - Fold the two standalone `OriginalFilename` tests into the existing full/partial metadata tests: they compiled the same binaries only to assert `OriginalFilename === ""`, which we can assert on the binaries we already built. Two fewer `--compile` invocations, same assertion. ## Stronger assertions - Invalid version cases now drain stderr and assert it contains `InvalidVersionFormat` (previously only checked `exitCode !== 0`). - Valid version cases now also assert `FileVersion` matches, not just `ProductVersion`. - `long strings`, `unicode`, and `special characters` now verify the written `VersionInfo` fields round-trip instead of only checking the exe exists. - `--windows-icon` test now asserts the build succeeded (it previously read `exitCode` into an unused variable). - `toMatchObject` replaces chains of per-field `toBe` so failures show a readable diff. ## Timings (Windows Server 2019, 16 vCPU, `bun bd test`) | | before | after | | --- | --- | --- | | current main | 80.0s | 27.8s / 28.0s / 28.3s | All 30 tests pass across three consecutive debug runs. On non-Windows hosts the Windows-gated describes still skip cleanly; the two cross-platform PE checksum tests at the bottom of the file are unchanged. --- **no test proof** · iteration 2 · Platform-specific test-only change; deferring to CI. --- test/bundler/compile-windows-metadata.test.ts | 328 +++++------------- 1 file changed, 95 insertions(+), 233 deletions(-) diff --git a/test/bundler/compile-windows-metadata.test.ts b/test/bundler/compile-windows-metadata.test.ts index b1a248097cae..475ed396b3d7 100644 --- a/test/bundler/compile-windows-metadata.test.ts +++ b/test/bundler/compile-windows-metadata.test.ts @@ -1,5 +1,4 @@ import { describe, expect, test } from "bun:test"; -import { execSync } from "child_process"; import { promises as fs } from "fs"; import { bunEnv, bunExe, isWindows, tempDir } from "harness"; import { join } from "path"; @@ -40,6 +39,40 @@ async function expectBuildOk(proc: Bun.Subprocess<"ignore", "pipe", "pipe">) { return { stdout, stderr, exitCode }; } +// Read all VersionInfo fields in a single PowerShell invocation (spawning +// powershell is ~0.5-1s on CI).

charset=UTF-8 Content-Transfer-Encoding: 8bit Follow-up to #36782, which unquarantined `spawn-maxbuf.test.ts` and exposed a latent boundary flake in a different subtest. ## Failure ``` 240 | expect(timeEnd - timeStart).toBeGreaterThan(100); // make sure it actually waits error: expect(received).toBeGreaterThan(expected) Expected: > 100 Received: 100 ✗ timeout kills the process > Bun.spawnSync [101.64ms] ``` Seen on main [build 87859](https://buildkite.com/bun/bun/builds/87859) (alpine 3.23 x64, retry passed) and [build 87890](https://buildkite.com/bun/bun/builds/87890) (debian 13 aarch64, red on every retry). The assertion has been in the file since #18293; it was hidden by the whole-file `[ FLAKY ]` quarantine until #36782 removed it. ## Cause The `spawnSync` timeout deadline is computed as `CLOCK_MONOTONIC + 100ms` at nanosecond precision (`js_bun_spawn_bindings.rs`: `now.add_ms(timeout_ms)`), and the timeout fires when `CLOCK_MONOTONIC >= deadline` (`SpawnSyncEventLoop::tick_with_timeout`). So by the time `spawnSync` returns, at least 100ms of monotonic time has elapsed. The test measures with `Date.now()`, which truncates the wall clock to whole milliseconds. For a real elapsed interval of 100.x ms, `floor(end) - floor(start)` can be exactly 100 (e.g. start at T+0.1ms → `Date.now()=T`, end at T+100.2ms → `Date.now()=T+100`). The test duration `[101.64ms]` in the CI output confirms the wait itself was not short. Local 500-iteration probe on release: ``` {"min":100,"hit100":7,"under100":0,"iterations":500} ``` The delta lands on exactly 100 in ~1.4% of runs and never goes below 100, so `>=` is the tight bound. ## Fix Change `toBeGreaterThan(100)` to `toBeGreaterThanOrEqual(100)`. The lower bound is kept because it is the only thing in this test that would catch `timeout: 100` being misread as `timeout: 0` (the `exitedDueToTimeout`/`signalCode` checks would still pass if the kill fired immediately). Node's own `test-child-process-spawnsync-timeout.js` only asserts the upper bound and relies on `error.code === 'ETIMEDOUT'`; Bun's `exitedDueToTimeout` is equivalent, but the `>= 100` here is cheap extra coverage. The sibling `toBeGreaterThan(1000)` assertions in the `timeout Infinity` block measure a child `sleep 1` plus `bunExe()` startup, which is always comfortably above 1000ms, so they are left as-is. ## Verification ``` $ bun bd test test/js/bun/spawn/spawn-maxbuf.test.ts 16 pass 0 fail ``` Five consecutive full-file debug runs pass.

The wrapper pins the server's JS wrapper through the traced `server` cached value, set in `ServerWebSocket::init`, which is what makes that raw pointer sound. `on_close` cleared that edge ("once closed, this socket no longer needs to pin the server"). That is wrong: `publish()`, `send()`, and the rest of the methods still dereference the handler on a closed socket (publishing via a closed socket is supported and broadcasts app-wide). Once the server was stopped and its JS wrapper collected, the deferred teardown freed the `NewServer` box while retained closed sockets still pointed into it. ### Fix Keep the traced `server` edge for the wrapper's whole lifetime (only the strong `this_value` ref is downgraded on close, so the socket wrapper itself stays collectible). The server's native allocation now strictly outlives every `ServerWebSocket` wrapper; once user code drops both, the whole group is collected as usual. ### Verification - New test `test/js/bun/websocket/websocket-server-stop-retained-ws.test.ts` crashes with ASAN heap-use-after-free before the fix, passes after (`[3,0,0,false]`: closed readyState, publish/send return 0, subscribe returns false, same as calling them on a stopped-but-alive server). - `bun bd test test/js/bun/websocket/` passes (the pre-existing `send() (benchmark)` test sits at the edge of its 30s timeout under debug+ASAN, unrelated to this change). Found while investigating #36788 (a 1.3.14 field crash showing wild-pointer corruption during `Bun.serve` shutdown: `panic(main thread): Segmentation fault at address 0x632D656475616C63`). That crash is not reproducible locally and cannot be confirmed to be this exact bug, but it is the same family: server teardown freeing state that retained objects still reference. --- **[review]** gate passed · iteration 1 · 2 files touched

**root cause** · written by the author bot The crash was a use-after-free in the ServerWebSocket close path, where the traced server reference was released during close cleanup even though a still-retained ServerWebSocket object could later reach it, causing teardown after server.stop() to dereference freed memory that had since been reused by unrelated string data. The fix keeps the traced server reference alive for closed sockets, releasing only the abort signal and downgrading the cached this reference, so retained sockets remain safe to touch after shutdown.

Nothing matched, so every async connect failure fell through to `ECONNREFUSED`. - The synchronous path (`connect_finish` after `do_connect()` errs) read the CRT's thread-local `_errno()`, which Winsock never sets, so it always saw 0 and fell through to the default. - `bsd.c`'s AF_UNIX connect path discarded `bsd_do_connect_raw`'s return value and let `closesocket()` overwrite `WSAGetLastError`. ## Fix - `bsd.c`: re-arm the WSA error with `WSASetLastError` after `bsd_close_socket` in both connect-failure tails, mirroring what the `bind`-failure path already does. - `Listener.rs` `connect_finish`: read `WSAGetLastError()` (mapped via `SystemErrno::init`) on Windows instead of `last_errno()`. - `socket_body.rs` `handle_connect_error`: normalize any incoming value `>= WSABASEERR` through `SystemErrno::init` before the whitelist; remap every whitelisted code (not just `ENOENT`/`ECONNREFUSED`) to its `UV_*` value so `err.errno` matches Node. Winsock AF_UNIX returns `WSAECONNREFUSED` for any path with no listening socket, existing or not, where Node (via libuv's `uv_pipe_connect`, which uses `CreateFile`) distinguishes `ENOENT`. `connect_finish` now refines `ECONNREFUSED` to `ENOENT` on the failure path when the target path does not exist, so a missing socket file still reports `ENOENT` while an existing non-socket file reports `ECONNREFUSED` (which the upstream test accepts). ## Verification Three Windows-only tests in `test/js/node/net/node-net.test.ts` cover the EADDRINUSE/ECONNRESET/ENOENT cases directly. The upstream `parallel/test-net-client-bind-twice.js`, `parallel/test-net-server-reset.js`, and `parallel/test-net-pipe-connect-errors.js` quarantines are removed. `parallel/test-net-pingpong.js` is left quarantined: that failure is the separate named-pipe half-close gap (`WindowsNamedPipe` issues `uv_close` instead of `uv_shutdown` on `end()`, and `on_read_error(EOF)` tears down the writer), which is a larger pipe-writer change. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Bun builds the absolute path via `join_abs_string_buf`, which preserves a trailing separator when the input (or the cached `top_level_dir`) carries one. `set_process_cwd` in `VirtualMachine.rs` appends a trailing `/` to `top_level_dir`, so after any `process.chdir()` the cached cwd ends in `/`. With `from = ""` nothing is joined on, the trailing `/` survives, and the reverse split emits an empty final segment as a spurious `//node_modules` entry. In the `--parallel` CI batch each worker runs several test files under `--isolate`; once any earlier file in that worker chdirs, the isolation restore goes through `set_process_cwd` too, and `node-module-module.test.js` then observes `_nodeModulePaths("") != _nodeModulePaths(".")`. ## Fix Strip trailing separators from the joined path (down to the root prefix) before splitting, matching Node's `path.resolve` semantics. ## Verification ```sh bun bd test test/js/node/module/node-module-module.test.js # 33 pass ``` New assertions fail on the released binary and pass on the debug build. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

When the wrapper is later collected, `~JS${name}` checks `if (m_sinkPtr)` before calling `${name}__finalize`, and `m_sinkPtr` is already null, so `finalize` is skipped. Every `close()` leaked the native backing: - `ArrayBufferSink`: the boxed struct and its `Vec` buffer. - `FileSink` (including `Bun.file(...).writer()` and `child.stdin`): the wrapper's +1 intrusive ref, so the struct and its IO buffers. - `NetworkSink` / `FetchRequestBodySink`: the wrapper's task ref. The HTTP response sinks only go through the controller path and are not affected. `filesink.test.ts` already carried a comment and a `detect_leaks=0` override acknowledging the FileSink case. ## Fix `${name}__doClose` now mirrors the destructor's teardown order after detaching: fire `m_onDestroy` (so Subprocess clears its `weak_file_sink_stdin_ptr` before the sink can be freed), then call `${name}__finalize(ptr)`. This runs even if `__close` set an exception, since the wrapper has already given up its pointer. Because `FileSink::finalize` is now reachable synchronously from `close()`, it no longer clears `pending` (which may hold a backpressured `write()` promise that `run_pending` still has to settle) or `readable_stream` (which may still be driving a spawn stdin). Both are released by `deinit()` via Box drop once the keep-alive and assignToStream refs are gone. `js_sink_ref` still gets cleared: it roots the wrapper itself. #29883 fixed the same bug in the Zig sources but was closed when those files were removed in the Rust migration. ## Verification ``` // before Direct leak of 600 byte(s) in 5 object(s) allocated from: ... #16 in ArrayBufferSink__construct Indirect leak of 20480 byte(s) in 5 object(s) allocated from: ... #15 in ::write_latin1 SUMMARY: AddressSanitizer: 21080 byte(s) leaked in 10 allocation(s). ``` - `arraybuffersink.test.ts`: LSAN-gated subprocess test for `close()` (fails on main with >16 KiB leaked, clean with the fix) and a guard that `write()`/`flush()`/`end()` after `close()` still throw "already been closed". - `filesink.test.ts`: `fileSinkInternals.liveCount()` check for `close()` (8 leaked on main, 0 with the fix); a guard that a backpressured `write()` promise still settles when `close()` runs before the drain; and the pre-existing EPIPE test drops its `detect_leaks=0` workaround. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Five small N-API entry points were dereferencing a `NULL` argument where Node.js returns `napi_invalid_arg`, and the `error_messages[]` table used by `napi_get_last_error_info` was two entries short. ### Null-dereference fixes | Function | Before | After | |---|---|---| | `napi_typeof(NULL, v, &r)` | segfault (`NAPI_CHECK_ENV_NOT_IN_GC` derefs env) | `napi_invalid_arg` | | `napi_is_exception_pending(NULL, &r)` | segfault (same) | `napi_invalid_arg` | | `napi_call_function(NULL, ...)` | segfault (`env->throwPendingException()` before null check) | `napi_invalid_arg` | | `napi_is_error(env, v, NULL)` | segfault (unchecked `*result = ...`) | `napi_invalid_arg` | | `napi_async_init(env, ..., NULL)` | segfault (unchecked `*async_ctx = ...`) | `napi_invalid_arg` | Node's `CHECK_ENV_NOT_IN_GC` begins with `CHECK_ENV(env)`; its `CHECK_ARG` guards every out-param. `NAPI_CHECK_ENV_NOT_IN_GC` now does the same, and `napi_is_error` / `napi_async_init` use the existing `get_out!` helper. ### `napi_get_last_error_info` table `error_messages[]` and `last_status` stopped at `napi_would_deadlock`, so when `napi_throw` returns `napi_cannot_run_js` (status 23, returned for v10+ addons during env-teardown finalizers) the caller saw `error_message == nullptr`. Added `"External buffers are not allowed"` and `"Cannot run JavaScript"` (verbatim from `node/src/js_native_api_v8.cc`) and bumped `last_status` to `napi_cannot_run_js`. The Rust `NapiStatus` enum gets the same two variants. Not included: the `napi_create_reference` v10 version-gate fix; that is #36089. ## How did you verify your code works? `test_napi_null_env_and_result` (standalone_tests.cpp) calls each of the five functions above with the NULL argument and is compared to Node via `checkSameOutput`: ``` $ node main.js test_napi_null_env_and_result '[]' napi_typeof(NULL env) -> 1 napi_is_exception_pending(NULL env) -> 1 napi_call_function(NULL env) -> 1 napi_is_error(NULL result) -> 1 napi_async_init(NULL result) -> 1 $ bun (main) main.js test_napi_null_env_and_result '[]' panic(main thread): Segmentation fault at address 0x48 ``` `test_last_error_cannot_run_js.c` is a `NAPI_VERSION=10` addon whose wrap finalizer runs at env teardown, calls `napi_throw` (returns `napi_cannot_run_js`), then `napi_get_last_error_info`.

Touching `.body` runs `locked_to_native_stream`, which `.take()`s `on_start_streaming`, copies `producer` onto the new `NewSource`, stores `locked.readable`, and calls `on_readable_stream_available`, but leaves `on_start_buffering` / `on_readable_stream_available` / `task` / `producer` on the PendingValue pointing at the tasklet. The clone/tee materialisation path does the same. Once the transfer completes, `on_progress_update`'s `is_done` cleanup derefs the tasklet to zero and frees it (`clear_stream_handlers` clears the ByteStream's `producer`, not the PendingValue's). The body stays `Locked{readable}` with the stale hooks. `write_file_internal`'s non-S3 `Locked` arm doesn't look at `locked.readable`; it calls `on_start_buffering(orig_task)` with the freed pointer, then parks on `on_receive_value`. `BodyValueBufferer` at `Body.rs:2593` has the same call for any body where `task.is_some()`. ### Fix Add `PendingValue::detach_producer()` and call it at both materialisation points after the ByteStream is wired up and `on_readable_stream_available` has fired. It clears `on_start_buffering` / `on_start_streaming` / `on_readable_stream_available` / `producer`, and clears `task` only when `on_receive_value` is unset: once a consumer has registered `on_receive_value`, `task` holds the consumer's ctx (read by `Value::resolve` / `Value::to_error_instance` via `.unwrap()`), not the producer being detached; every `on_receive_value` setter writes `task` alongside it so the stale producer pointer cannot be in `task` in that state. Delivery is then owned by the ByteStream's `NewSource.producer`, the single live back-reference already cleared by `clear_stream_handlers` on teardown. The `Bun.write` hang on a stream-backed body (`on_receive_value` never fires) is unchanged here; #32906 and #35531 cover it. Both of those still call `on_start_buffering(producer_task)` before checking for a readable, so neither removes this UAF on its own. ### Verification `test/js/bun/io/bun-write.test.js` gains: - an ASAN-gated `it.each` covering the three exposure shapes (`getReader().read()` then `releaseLock()`; bare `resp.body`; `resp.clone()`). Each spawns a subprocess that runs 8 iterations against a 200 KB loopback body and asserts `{stdout: "done", stderr: "", exitCode: 0}`. `ASAN_OPTIONS=symbolize=0:detect_leaks=0` keeps the crashing child's exit prompt (symbolize) and suppresses the known `WriteFileWaitFromLockedValueTask` leak from the #13237 hang (detect_leaks). - a test that drives `Bun.write(path, HTMLRewriter.transform(resp))` then `out.body` through an async input body and asserts the write resolves with the rewritten bytes, guarding the `on_receive_value` case. Without the `src/` change the three ASAN cases fail on the heap-use-after-free; with it all four pass. `body.test.ts` (448 pass), `body-stream.test.ts` (9086 pass), `html-rewriter.test.js` (69 pass) and `fetch-response-finalizer-sweep.test.ts` are unchanged. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

None of these crash; they break addons that branch on `status == X`. This aligns each to Node.js, verified against `js_native_api_v8.cc` / `node_api.cc` on `v26.x`. ## Before / after `test_napi_status_codes_node26` (diffed byte-for-byte against Node via `checkSameOutput`): ``` bun (before) node / bun (after) napi_wrap(number) status=2 status=1 napi_unwrap(number) status=2 status=1 napi_remove_wrap(number) status=2 status=1 napi_add_finalizer(number) status=2 status=1 napi_coerce_to_number(Symbol) status=10 status=6 pending=1 napi_coerce_to_string(Symbol) status=10 status=3 pending=1 napi_coerce_to_object(null) status=10 status=2 pending=1 napi_run_script(throw) status=10 status=9 pending=1 napi_run_script(syntax) status=10 status=9 pending=1 napi_create_bigint_words(INT_MAX+1) status=10 p=1 status=1 pending=0 napi_create_buffer(SIZE_MAX) status=10 status=9 pending=1 napi_create_buffer_copy(SIZE_MAX) status=10 status=9 pending=1 napi_throw_error while one is pending status=0 status=10 (first kept) node_api_post_finalizer(NULL) status=1 status=0 napi_make_callback(recv=NULL) status=0 status=1 napi_make_callback(argc>0,argv=NULL) status=0 status=1 napi_make_callback(func=number) status=5 status=1 napi_ref_threadsafe_function(env=NULL) status=1 status=0 napi_unref_threadsafe_function(env=NULL) status=1 status=0 napi_ref_threadsafe_function last_error cleared preserved ``` ## Changes **`src/jsc/bindings/napi.cpp`** - New `NAPI_RETURN_STATUS_IF_EXCEPTION(env, status)` macro alongside `NAPI_RETURN_IF_VM_EXCEPTION`, for call sites where Node.js reports a specific code while leaving the thrown exception pending. Used by the coerce-to-\*/create-buffer paths below and by the two pre-existing `napi_instanceof` call sites (no behavior change there). - `napi_wrap` / `napi_unwrap` / `napi_remove_wrap` / `napi_add_finalizer`: non-object `js_object` returns `napi_invalid_arg` (was `napi_object_expected`). Node: `RETURN_STATUS_IF_FALSE(env, value->IsObject(), napi_invalid_arg)` in `v8impl::Wrap/Unwrap`. - `napi_coerce_to_number` / `_string` / `_object`: when the coercion throws, return `napi_{number,string,object}_expected` (was `napi_pending_exception`). The thrown exception stays pending. Node: `GEN_COERCE_FUNCTION` -> `CHECK_MAYBE_EMPTY(..., napi_X_expected)`. - `napi_run_script`: compile/eval error returns `napi_generic_failure` (was `napi_pending_exception`). Exception stays pending on the env. Node: `CHECK_MAYBE_EMPTY(env, maybe_script, napi_generic_failure)` / same for `Run()`. - `napi_create_buffer` / `napi_create_external_buffer`: allocation failure returns `napi_generic_failure` (was `napi_pending_exception`). Node: `CHECK_MAYBE_EMPTY(env, maybe, napi_generic_failure)`. - `napi_create_bigint_words`: `word_count > INT_MAX` returns `napi_invalid_arg` with no throw (was a thrown `RangeError` + `napi_pending_exception` for `INT_MAX < word_count <= UINT_MAX`). Node: `RETURN_STATUS_IF_FALSE(env, word_count <= INT_MAX, napi_invalid_arg)`. Counts between JSC's bigint limit and `INT_MAX` still throw, guarded before `createFromWords` so we never read past the caller's buffer (V8 checks its limit before reading; JSC trims trailing zeroes first). - `napi_throw_error` / `napi_throw_type_error` / `napi_throw_range_error` / `node_api_throw_syntax_error`: if an exception is already pending, return `napi_pending_exception` and leave it untouched (was `napi_ok`, overwriting the first exception). Node uses `NAPI_PREAMBLE` for all four. The internal call sites in `napi_instanceof` / `napi_create_dataview` sit behind a preamble that has already rejected a pending exception, so they are unaffected. - `node_api_post_finalizer`: accept a NULL `finalize_cb` (was `napi_invalid_arg`). Node uses only `CHECK_ENV` and enqueues unconditionally; `napi_internal_enqueue_finalizer` early-returns on a null callback. **`src/runtime/napi/napi_body.rs`** - `napi_create_string_utf8`: creation failure returns `napi_generic_failure` (was `napi_pending_exception`), consistent with Bun's own latin1/utf16 variants and Node's `CHECK_MAYBE_EMPTY`. - `napi_make_callback`: NULL `recv` / `argc > 0 && argv == NULL` / non-function `func` all return `napi_invalid_arg` (was: accepted / accepted / `napi_function_expected`). Node: `CHECK_ARG(env, recv)`, `if (argc > 0) CHECK_ARG(env, argv)`, `CHECK_TO_FUNCTION` (-> `napi_invalid_arg`). - `napi_resolve_deferred` / `napi_reject_deferred`: resolve/reject failure returns `napi_generic_failure` (was `napi_pending_exception`). Node: `RETURN_STATUS_IF_FALSE(env, success.FromMaybe(false), napi_generic_failure)` in `ConcludeDeferred`. - `napi_create_buffer_copy`: allocation failure returns `napi_generic_failure` (was `napi_pending_exception`). - `napi_ref_threadsafe_function` / `napi_unref_threadsafe_function`: ignore `env` (basic-env functions) and return `napi_ok` without touching `last_error`. Node: `CHECK_NOT_NULL(func); return ...->Ref();` with no env check and no `napi_set_last_error`. ## Not in this PR `napi_create_typedarray` / `napi_create_dataview` non-ArrayBuffer -> `napi_invalid_arg` and the coded-RangeError alignment for typedarray bounds are covered by #34132. ## Coverage `test_napi_status_codes_node26` pins every change that is reachable without engine OOM. The remaining `pending_exception -> generic_failure` edits are alignment-by-inspection only: - `napi_create_string_utf8` creation failure: `length > INT_MAX` is rejected with `napi_invalid_arg` first, so the failure arm needs a true JSC string-allocation OOM. - `napi_create_external_buffer` allocation failure: the empty-buffer and external-bytes paths do not have a size pre-check that can be tripped deterministically. - `napi_resolve_deferred` / `napi_reject_deferred` failure: the underlying `JSPromise::resolve/reject` only `Err`s on VM termination; the deferred handle is freed on first use, so a second call is UB rather than a testable failure. ## Verification ``` USE_SYSTEM_BUN=1 bun test test/napi/napi.test.ts -t 'returns the same napi_status' -> fail (21/21 lines differ from Node) bun bd test test/napi/napi.test.ts -t 'returns the same napi_status' -> pass (Bun output == Node output) ``` The vendored Node test suites for `test_bigint`, `test_conversions`, `test_error`, `test_exception`, `6_object_wrap`, `8_passing_wrapped`, `test_promise`, `test_function`, `test_general`, `test_object` all pass. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

From 804094ffa7b477ffec7c17bad92d16dfc590729d Mon Sep 17 00:00:00 2001 From: robobun Date: Mon, 3 Aug 2026 00:52:17 -0700 Subject: [PATCH 055/304] napi: re-sync public N-API headers from Node.js 26 (#36804) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## What Copies `js_native_api.h`, `js_native_api_types.h`, `node_api.h`, and `node_api_types.h` from `nodejs/node@v26.x` into `src/runtime/napi/`. Three of the four files are byte-identical to upstream; `js_native_api_types.h` carries Bun's three intentional divergences (documented in the new `src/runtime/napi/README.md`): - `struct NapiEnv*` instead of `struct napi_env__*` on the three env `typedef` lines, so the opaque tag matches `src/jsc/bindings/napi.h`'s concrete type. - Default `NAPI_VERSION` is 10 (upstream: 8). Bun's header has defaulted to 10 since #20772 so the v9/v10 declarations Bun already implements are visible without opting in; keeping upstream's 8 would have been a silent regression for `cc()` users. - The upstream `NAPI_EXPERIMENTAL` `#warning`/`#pragma message` block is dropped. `cc()`'s TinyCC backend routes `#warning` through its error callback, so an includer that `#define NAPI_EXPERIMENTAL` would fail to compile against the bundled header; Bun's own `-Werror` C++ build would also break. `scripts/run-clang-format.sh` and `.github/workflows/CLAUDE.md` still excluded the pre-move `src/napi/` path, so autofix.ci had been free to reformat these headers; both are pointed at `src/runtime/napi/` now. ## Why Bun's in-tree headers had drifted several releases behind Node. Addons compiled against them (via `cc()`'s bundled `#include `, or anything pointing `-I` at `src/runtime/napi`) would: - fail to compile when referencing `node_api_basic_env`, `node_api_nogc_env`, `node_api_basic_finalize`, `node_api_noenv_finalize`, `napi_cleanup_hook`, `node_api_addon_get_api_version_func`, or `NAPI_CDECL`; - not see `node_api_symbol_for` / `node_api_{create,throw}_syntax_error` / `node_api_get_module_file_name` without defining `NAPI_EXPERIMENTAL` (Node moved these to `NAPI_VERSION >= 9`); - not see `node_api_post_finalizer` / `node_api_create_buffer_from_arraybuffer` in the header at all (Bun already implements both); - miss the `NODE_API_EXPERIMENTAL_HAS_*` feature macros and `NODE_API_NO_EXTERNAL_BUFFERS_ALLOWED` guard; - most importantly, **not export `node_api_module_get_api_version_v1`** when using `NAPI_MODULE_INIT()`, because Bun's macro still expanded to the deprecated `NAPI_C_CTOR` + `napi_module_register` path. Both Bun (`BunProcess.cpp:708`) and Node `dlsym` that symbol to learn the addon's declared `NAPI_VERSION`; without it the host falls back to version 8 regardless of what the addon was built for. ## Build integration Bun compiles `napi.cpp` with `NAPI_EXPERIMENTAL` defined. With the upstream headers that would make `node_api_basic_env` a `const`-qualified alias and break every existing `extern "C"` signature, so `NODE_API_EXPERIMENTAL_NOGC_ENV_OPT_OUT=1` is added next to `NAPI_EXPERIMENTAL=ON` in `scripts/build/flags.ts` (the same opt-out `test/napi/napi-app/binding.gyp` already passes). The now-redundant local `node_api_noenv_finalize` typedef in `napi.cpp` is dropped. ## Test `test/napi/napi-value-ffi.test.ts` gains: - an "in-tree N-API headers" case that compiles `bundled_napi_headers_node26.c` against `src/runtime/napi/` with the system `cc` and dlopens the result. Before: `error: unknown type name 'node_api_basic_env'`, `NAPI_CDECL` unrecognised, `node_api_get_module_file_name` undeclared. After: compiles; `node_api_module_get_api_version_v1()` and `use_node26_types()` both return the header's default `NAPI_VERSION` (10). - two `cc()`-path cases (TinyCC, `todoIf(isASAN)` like the existing one) compiling the same fixture and a `#define NAPI_EXPERIMENTAL` variant, so a future resync that reintroduces the `#warning` or drops the 10 default is caught on non-ASAN lanes. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

The sole reference outside its own module was `node_os.rs:269` doing `<&'static str>::from(ErrorCode::ERR_SYSTEM_ERROR)`, which just produces the string `"ERR_SYSTEM_ERROR"`. Three other call sites in the same file (`node_os.rs:938/1220/1539`) already use `BunString::static_("ERR_SYSTEM_ERROR")` directly, so the remaining one now does the same. The `jsc::ErrorCode` type (backed by `ErrorCode.generated.rs`) is the live `ERR_*` table; this enum was a parallel dead one. - `rg -n 'nodejs_error_code' src/ build/debug/codegen/ src/codegen/` → only the `mod` declaration and two explanatory comments (both updated). - **`dir_iterator::IteratorError`** (11 lines) + **`runtime::Error::DirIterator`** variant (3 lines): the enum is never constructed (`rg 'IteratorError::' src/ build/debug/codegen/` → 0 hits), so the `#[from]` on `Error::DirIterator` can never fire either. - **`VectorArrayBuffer::to_js`** (4 lines): every caller reads `.value` directly; `to_js` was never invoked and is not a trait impl. - **`src/resolver/fs.rs`** commented-out Zig stubs `statBatch/stat/readFile/readDir` (9 lines): never implemented. ## Verification ``` rg -w src/ build/debug/codegen/ src/codegen/ bun bd bun run rust:check-all # 10 ok, 0 failed bun bd test test/js/node/os/ test/js/node/fs/fs.test.ts -t readdir bun bd test test/bundler/bundler_loader.test.ts bun bd test test/internal/source-lints/ ``` A source-lint test (`test/internal/source-lints/dead-symbols-nodejs-error-code.test.ts`) asserts none of these reappear. ## Also scanned (nothing removed) `src/http/**` (36 files), `src/install/**`, `src/resolver/**`, `src/ast/**`, `src/semver/**`, `src/valkey/**`, `src/sql/postgres/**`, `src/collections/**`. Several initial candidates turned out to have callers under a different crate or via method-call syntax: `collections::StringMap` (sql_jsc), `semver::string::ArrayHashContext` (install/lockfile), `NewWriter::{int8,f64,bun_string}` (sql_jsc), `Level::{gt,eql}` (js_parser), `SinglyLinkedList::len` (bake/memory_cost), `Target::is_node` (resolve_builtins), `{Parse,Decode}DataURLError::name()` (bundler/transpiler).

Reproduces 5/5 under ASAN on `main`, clean on `5b7c3cacbe63` (before #36624). ``` READ of size 1 in NewSource::cancel (ReadableStream.rs:936) <- ReadableStream::done <- ReadableStream::error <- BodyAbortListener::on_abort (Response.rs:142) <- AbortSignal::runAbortSteps <- Timeout::run <- __bun_fire_timer freed by: JSDestructibleObjectDestroyFunc <- PreciseAllocation::sweep <- sweepPreciseAllocations <- Heap::sweepInFinalize allocated by: Box::new(NewSource<..>) <- Value::to_readable_stream <- Response.body getter ``` Minimal repro (crashes at iteration 0 on debug and release ASAN): ```js const server = Bun.serve({ port: 0, fetch: () => new Response(Buffer.alloc(20000, "x")) }); async function one(signal) { const resp = await fetch(server.url, { signal }); const rd = resp.body.getReader(); await rd.read(); await rd.cancel(); } for (;;) { const ac = new AbortController(); await Promise.all([one(ac.signal), one(ac.signal), one(ac.signal)]); Bun.gc(false); // must NOT be gc(true) await Bun.sleep(5); ac.abort(); await Bun.sleep(5); } ``` ## Cause #36624 changed `readable_stream::Strong` so that `check_body_stream_ref` downgrades `Body.Locked.readable` from a `bun_jsc::Strong` to a raw `weak: JSValue` once the Response wrapper's traced `m_stream` WriteBarrier slot owns the stream. That raw JSValue is never cleared when the stream is collected. After `reader.cancel()` (ByteStream path) or once the body is fully buffered (ByteBlobLoader path), nothing but the Response wrapper's `m_stream` roots the stream. When the user drops the Response, one eden GC: 1. reaps weak handles (so a real `JSC::Weak` would already read `None`), 2. runs `sweepInFinalize` -> `sweepPreciseAllocations`, which sweeps the `JS{Bytes,Blob}InternalReadableStreamSource` cell **synchronously**; its destructor runs `NewSource::finalize` -> `decrement_count` -> `drop(Box>)`, 3. leaves the `JSResponse` wrapper's MarkedBlock cell for lazy sweep. `Response::finalize` (the wrapper cell destructor) is what sets `js_ref` to `Finalized` and drops `abort_listener`, so in that window the native `Response` is still alive, `Locked.readable` still holds the stream's raw JSValue, and `BodyAbortListener` is still registered. `AbortSignal.timeout` / `ac.abort()` then fires: * `on_abort` -> `get_body_readable_stream` reaches the dead stream through either `js_ref()` (raw JSValue to the dead-but-unswept wrapper) or `Locked.readable`'s raw JSValue -> `ReadableStreamTag__tagged` -> `m_nativePtr` -> the destructed source cell's `m_ctx` -> the freed `Box>`, and * `Value::to_error_instance` reads the same handle via `strong_readable.get()` -> `bytes.on_data()`. `Bun.gc(true)` does not reproduce: a full synchronous sweep runs the wrapper destructor in the same pass, which drops the listener before abort can fire. ## Fix * `readable_stream::Strong::weak` is now `bun_jsc::Weak<()>` instead of a raw `JSValue`. `downgrade()` creates it with the new `WeakRefType::None` (no finalize owner; `JSC::Weak` accepts a null owner). `get()` / `has()` / `is_disturbed()` / `tee()` all see `None` once the stream is reaped, so `Value::to_error_instance` and every other `Locked.readable` reader skip the freed `NewSource` deref. * `BodyAbortListener::on_abort` reads the stream via `Locked.readable` directly instead of `get_body_readable_stream`, whose `js_ref()` path would still read a raw `JsRef::Weak(JSValue)` to the dead-but-unswept wrapper. `Locked.readable.get()` returns the live stream when a reader roots it without the wrapper, and `None` exactly when the stream (and its `NewSource` box) is collected. * `bun_jsc::Weak::create_passive` and a `WeakRefType::None` arm in `Bun__WeakRef__new` support an ownerless `JSC::Weak`. No user-visible behaviour changes: when the stream is collected `readable.error()` was already a no-op (`webStreamControllerError` early-returns on a non-Readable stream; `NewSource::cancel` early-returns on `cancelled`); when the stream is alive `readable.error()` runs exactly as before. ## Verification * `test/js/web/fetch/fetch-abort-after-cancel-gc-fixture.ts` + test: crashes at iteration 0 on `main` under debug+ASAN (`bun bd test`), passes with this PR. * release+ASAN: 5/5 clean on both the fixture (100 iters) and the original fuzzer repro (300 iters); `main` crashes 5/5 and 4/4 respectively. * `test/js/bun/http/serve-http3.test.ts` "client abort during streaming response" passes 3/3 on release+ASAN (regressed on the first commit of this PR; fixed in c5da841). * #36624's leak regression test `test/regression/issue/29267` still passes (the downgrade is preserved; only the storage is now a real Weak). * `test/js/web/fetch/{fetch-abort-stream-body,body,body-stream,body-clone,fetch-abort-queued,fetch-stream-cancel-leak}.test.ts` and `test/js/web/streams/readable-stream-terminal-barrier-release.test.ts` unchanged vs `main`. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

Every removed symbol was verified via `rg` across `src/` and `build/debug/codegen/` to have zero remaining references; `bun bd` and `bun run rust:check-all` (all CI target triples) pass. ## Whole-file deletions (C++ headers) - `src/jsc/bindings/TextCodecASCIIFastPath.h` (78 lines): never `#include`d anywhere under `src/`, `scripts/`, `cmake/`, or generated code. Defines `PAL::UCharByteFiller` / `PAL::copyASCIIMachineWord`, neither referenced. - `src/jsc/bindings/webcore/Node.h` (108 lines): defines `WebCore::Node` which is never instantiated, subclassed, or referenced as a type. No `WTF_MAKE_TZONE_ALLOCATED_IMPL(Node)` exists so it could never link. Removed the two `#include "Node.h"` lines in `WebCoreOpaqueRoot.h` and `EventTargetHeaders.h` (neither file uses the type). - `src/jsc/bindings/webcore/JSDOMWindow.h`, `JSServiceWorker.h`, `JSWindowProxy.h`: one-line stub headers. Removed their `#include` sites in `JSMessageEvent.cpp`, `JSMessageEventCustom.cpp`, and the commented-out includes in `JSEventTargetCustom.cpp`. ## Dead `extern "C"` exports (lost their Rust caller in #35002) - `highway_strings.cpp`: `highway_char_frequency` + `ScanCharFrequencyImpl` (69-line SIMD body) + `HWY_EXPORT`. Whole-repo `rg -w highway_char_frequency` = 1 hit (its own definition). - `TextCodecWrapper.cpp`: `Bun__isEncodingSupported`, `Bun__getCanonicalEncodingName`. Whole-repo `rg` = 1 hit each. - `StrongRef.cpp` / `.h`: `Bun__StrongRef__get`, `Bun__StrongRef__clear`. `src/jsc/Strong.rs` only declares `new`/`set`/`delete`; reads go through a direct pointer load per the comment at `StrongRef.cpp:19-26`. Also removed `StrongRootBlock::clearValue` which was only called from `Bun__StrongRef__clear`. - `InspectorLifecycleAgent.cpp`: `Bun__LifecycleAgentReportReload` wrapper + `InspectorLifecycleAgent::reportReload()` method + header decl. No Rust caller. - `InspectorBunFrontendDevServerAgent.cpp`: `InspectorBunFrontendDevServerAgent__notifyClientErrorReported` / `notifyGraphUpdate` wrappers + `clientErrorReported()` / `graphUpdate()` class methods + header decls. `inspector_agent.rs` declares the 7 sibling `notify*` wrappers but not these two. - `InspectorBunFrontendDevServerAgent.h`: removed the stale 9-entry `extern "C"` block that declared `BunFrontendDevServerAgent__notify*` (no `Inspector` prefix), which never matched the actual `InspectorBunFrontendDevServerAgent__notify*` definitions or the Rust imports. - `JSS3File.cpp`: `static bool customHasInstance(...)` is a file-scope static function, never referenced in the file. `JSS3File`'s `StructureFlags` is `Base::StructureFlags` with no `ImplementsHasInstance`, so `CREATE_METHOD_TABLE` cannot pick it up. Removed the matching `JSS3File__hasInstance` forward decl, the `has_instance` helper in `S3File.rs`, and its `#[no_mangle]` export whose only caller was this static. ## Commented-out C++ (>6 months stale per `git blame`) - `JSTextEncoder.cpp`: disabled DOMJIT declarations, `DOMJIT::Signature` statics, `HashTableValue` entries, and two `JSC_DEFINE_JIT_OPERATION` bodies (83 lines total). Commented out since 2024-09; the non-DOMJIT `encode`/`encodeInto` entries remain. - `JSURLSearchParams.cpp`, `JSErrorEvent.cpp`, `JSDOMException.cpp`: `#if ENABLE(BINDING_INTEGRITY)` vtable-pointer scaffolding inside and before `toJSNewlyCreated`. Commented out since 2022-03. - `JSPerformance.cpp`, `JSDOMURL.cpp`: `JSDOMWindowBase`-gated `deleteProperty` paths in `finishCreation`/`initializeProperties`. Commented out since 2024. - `JSWorkerOptions.cpp`: `credentials`/`type` dictionary-member parsing. Commented out since 2023-07 / 2025-01. - `JSEventListener.cpp`: `handleBeforeUnloadEventReturnValue` helper and its call site. Commented out since 2022-03. - `PerformanceUserTiming.cpp`: `restrictedMarkFunctions` lookup inside `convertMarkToTimestamp`. Commented out since 2024-01. ## Rust - `Blob.rs`: `pub struct Inline` + `impl Inline` + `impl Default for Inline` (48 lines). `rg 'InlineBlob|blob::Inline'` shows every reference is inside a `//` comment; the `Any` enum at `Blob.rs:6353` has no `Inline` variant. - `Body.rs`, `server/RequestContext.rs`: removed the commented-out `InlineBlob` match arms that referenced the deleted struct. - `S3File.rs`: `has_instance` + `JSS3File__hasInstance` export (only caller was the removed C++ static; see above). - `streams.rs`: `BufferAction::get` (zero callers; all `.get()` calls on `buffer_action` resolve to `JsCell::get`). - `FileReader.rs`: `pub const TAG` (zero references). ## src/js (>6 months stale per `git blame`) - `builtins/Ipc.ts`: 131-line commented-out `handleConversion` map (net.Server/net.Socket/dgram.*). Blame 2025-05-06. - `internal/fs/streams.ts`: commented-out `fastPath._getFd()` block. Blame 2025-01-25. - `node/worker_threads.ts`: two commented-out type imports. Blame 2023-08-07. ## Verification - `bun bd`: builds clean - `bun run rust:check-all`: 10 ok, 0 failed (all target triples) - Smoke tests pass: `text-encoder.test.js` (42 pass), `worker_threads.test.ts` (91 pass), `body.test.ts` (448 pass), `url.test.ts` (18 pass), `performance.test.js` (7 pass) - `test/internal/source-lints/dead-symbols-webcore-inline-extern.test.ts` added: fails on `main` (every check matches), passes after this diff ## Followups (not in this diff) - `BunFrontendDevServerFrontendDispatcher::clientErrorReported`/`graphUpdate` and `LifecycleReporterFrontendDispatcher::reload` in the generated inspector protocol are now unreferenced from C++; trimming those lives in the protocol JSON, out of scope here. Downstream consumers that were already inert before this PR (no Rust producer ever existed): the `LifecycleReporter.reload` listener in `packages/bun-vscode/src/features/diagnostics/diagnostics.ts`, the `ReloadEvent` type in `packages/bun-inspector-protocol/src/protocol/jsc/index.d.ts`, and the two `test.todo` blocks waiting on `clientErrorReported`/`graphUpdate` in `test/cli/inspect/BunFrontendDevServer.test.ts`. Scanned and found clean (no confident dead symbols): `src/install/` (lockfile/npm/migration/yarn/bin/isolated_install), `src/sql/postgres/`, `src/http/` (websocket, h3_client, AsyncHTTP, HTTPThread, etc.), `src/semver/`, `src/resolver/`, `src/ast/`, `src/collections/`, `src/bun_core/`, `src/runtime/api/`, `src/runtime/node/`, `src/dotenv/`, `src/patch/`, `src/glob/`, `src/event_loop/`, `src/threading/`, `src/uws/`, `src/crash_handler/`, `src/valkey/`, `src/runtime/socket/`. --- **[review]** gate passed · iteration 2 · 46 files touched

Tightens the GitHub Actions workflows against the credential-theft patterns behind this year's action supply-chain incidents (persisted checkout tokens, floating tags, `${{ }}` in shell), and deletes workflows that have been dead for a year or more — one of which referenced the compromised `actions-cool/issues-helper@v3`. | Change | Scope | |---|---| | `actions/checkout` → v7.0.1 SHA, `persist-credentials: false` | all 30 checkouts; homebrew tap push now passes its token explicitly | | top-level `permissions: contents: read` | 27 workflows that had none (job-level grants unchanged) | | `${{ inputs/steps/env.* }}` moved from `run:` into `env:` | setup-bun action, release, vscode-release, update-sqlite3, auto-assign-types, format/clippy/miri | | third-party actions dropped | `JS-DevTools/npm-publish` → `npm publish`; `git-auto-commit-action` → plain git; `oven-sh/setup-bun` v1/v2 → in-repo `setup-bun` | | triage jobs | `anthropics/claude-code-action/base-action` v1.0.183 (old mirror stopped tagging), model `claude-opus-5` | | Bun used by CI jobs | 1.3.14 | | `release.yml` `is-latest` | read boolean `inputs.is-latest`; `github.event.inputs.is-latest` is the string `"false"` (truthy), so manual dispatches always published as latest | | new `dependabot.yml` | github-actions, weekly, 7-day cooldown | | Deleted | Why | |---|---| | `labeled.yml.disabled` | disabled Nov 2025; used `actions-cool/issues-helper@v3` (compromised May 2026 — never ran here) | | `comment-lint.yml.disabled` | disabled Nov 2025; listened for a workflow that no longer exists | | `update-root-certs.yml` | disabled in the Actions UI since Aug 2025; every run was `startup_failure` | | `test-bump.yml`, `actions/bump`, release `bump` job | `scripts/bump.ts` was removed in 2024 | ### How did you verify your code works? `zizmor .github`: 54 → 5 findings; the remainder are three `pull_request_target` workflows that never check out PR code and a `GITHUB_PATH` append in setup-bun. All YAML parses. PR-triggered workflows (lint/format/clippy/bun-types/packages-ci) exercise the checkout/permissions/setup-bun changes on this PR. Not exercisable until the next release: the `npm-types` publish step and the homebrew tap push in `release.yml`. --- .github/actions/bump/action.yml | 42 --- .github/actions/setup-bun/action.yml | 24 +- .github/dependabot.yml | 13 + .github/workflows/auto-assign-types.yml | 6 +- .github/workflows/auto-close-duplicates.yml | 7 +- .github/workflows/auto-label-claude-prs.yml | 3 + .github/workflows/bun-types.yml | 4 +- .github/workflows/claude-dedupe-issues.yml | 11 +- .../workflows/claude-find-issues-for-pr.yml | 15 +- .github/workflows/clippy.yml | 8 +- .github/workflows/close-stale-robobun-prs.yml | 3 + .github/workflows/comment-lint.yml.disabled | 85 ------ .github/workflows/format.yml | 16 +- .github/workflows/freebsd-smoke.yml | 6 +- .github/workflows/labeled.yml.disabled | 278 ------------------ .github/workflows/lint.yml | 9 +- .github/workflows/miri.yml | 8 +- .github/workflows/on-slop.yml | 3 + .github/workflows/packages-ci.yml | 7 +- .github/workflows/release.yml | 124 ++++---- .github/workflows/source-lints.yml | 4 +- .github/workflows/stale.yaml | 3 + .github/workflows/test-bump.yml | 32 -- .github/workflows/update-cares.yml | 7 +- .github/workflows/update-hdrhistogram.yml | 7 +- .github/workflows/update-highway.yml | 7 +- .github/workflows/update-libarchive.yml | 7 +- .github/workflows/update-libdeflate.yml | 7 +- .github/workflows/update-lolhtml.yml | 7 +- .github/workflows/update-lshpack.yml | 7 +- .github/workflows/update-root-certs.yml | 83 ------ .github/workflows/update-sqlite3.yml | 12 +- .github/workflows/update-vendor.yml | 9 +- .github/workflows/update-zstd.yml | 7 +- .github/workflows/vscode-release.yml | 13 +- 35 files changed, 243 insertions(+), 641 deletions(-) delete mode 100644 .github/actions/bump/action.yml create mode 100644 .github/dependabot.yml delete mode 100644 .github/workflows/comment-lint.yml.disabled delete mode 100644 .github/workflows/labeled.yml.disabled delete mode 100644 .github/workflows/test-bump.yml delete mode 100644 .github/workflows/update-root-certs.yml diff --git a/.github/actions/bump/action.yml b/.github/actions/bump/action.yml deleted file mode 100644 index bb91d1f6be69..000000000000 --- a/.github/actions/bump/action.yml +++ /dev/null @@ -1,42 +0,0 @@ -name: Bump version -description: Bump the version of Bun -

name: Build (inspector protocol) From 2ed8ed65682f89fcecaa8acad5dd69b0357a52de Mon Sep 17 00:00:00 2001 From: robobun Date: Mon, 3 Aug 2026 11:43:07 -0700 Subject: [PATCH 061/304] Upgrade WebKit to 3722912ff800 (#36794) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Upgrades the WebKit fork to upstream WebKit/WebKit@3722912ff800 (2026-08-02) via oven-sh/WebKit#383. oven-sh/WebKit#383 is merged; `WEBKIT_VERSION` points at the merge commit `e6e37cda216c0292ae68c30c84a9dc8601d0fba5`. ## Bun-side changes Upstream `90b2ecf79ae3` keys `m_loadedModules` on `(specifier, ScriptFetchParameters::Type)` and threads the type through `ImportEntry`, `ExportEntry`, `StarExportEntry`, and `ModuleAnalyzer::appendRequestedModule`. Under `bun test --isolate` (the `BunTranspiledModule` path), Bun'''s synthesized record must agree with what JSC'''s own `ModuleAnalyzer` would produce from the printed source; a mismatch fails the BUN_DEBUG record diff in debug and null-derefs `hostResolveImportedModule` in release. - `analyze_transpiled_module` / `js_printer`: every `RecordKind` now carries one trailing `FetchParameters` slot. `add_import_info_*` and `add_export_info_*` accept it; `finalize()` propagates the source import'''s slot through the Local->Indirect conversion. `RequestedModules` dedupes on `(specifier, Type, phase)`. - `analyze_jsc.rs`: decodes the trailing slot to the JSC `Type` enum and passes it to every `addImportEntry*` / `addIndirectExport` / `addNamespaceExport` / `addStarExport`; buffer validation is per-slot so only the trailing slot accepts the wider `FetchParameters` sentinel range. - `BunAnalyzeTranspiledModule.cpp`: all seven `addImportEntry*` / `add*Export` functions take `uint8_t moduleRequestType` and set `.moduleRequestType` explicitly; `dumpRecordInfo()` prints `type(N)` for import/export/star entries; `static_assert` pins the ordinal values `to_script_fetch_parameters_type()` hardcodes. - `RuntimeTranspilerCache` `EXPECTED_VERSION` -> 25 (esm_record layout change). ## WebKit-side changes (oven-sh/WebKit#383) - 17 merge conflicts resolved in JSC/WTF; fork's `USE(BUN_JSC_ADDITIONS)` hunks preserved. - Fork `ffi/` code adapted to upstream's 32-bit removal (`USE_JSVALUE64` macro deleted, `is64Bit()` removed, `payloadFor` -> `lowWordFor`). - `InspectorDebuggerAgent.cpp`: handle `BunTranspiledModule`/`Synthetic` in new `scriptTypeForScript` switch. - Recorded `01aaa3e0be0c` as ancestor via `-s ours` (oven-sh/WebKit#352 was a squash merge). ## How did you verify your code works? - `bun run jsc:build:debug` builds and the `jsc` shell runs (`-e 'print(42)'` -> `42`). - `bun run build:local -p '42'` links and runs against the local merged WebKit. - oven-sh/WebKit#383 preview build green on all 38 platform variants. - `bun bd -p 'process.versions.webkit'` -> `preview-pr-383-b9ea4dc5`. - New test `test/js/bun/jsc/webkit-upgrade-3722912f.test.ts`: 4/4 pass with `bun bd test`, 3/4 fail with `USE_SYSTEM_BUN=1 bun test` (old JSC lacks `Iterator.prototype.includes`, returns `""` for cyclic join, `WebAssembly.Exception.length === 1`). ## JavaScriptCore/WTF/bmalloc changes since 01aaa3e0be0c (Jul 25) Upstream range: WebKit/WebKit@01aaa3e0be0c...3722912ff800 (474 commits total, 110 touching JSC/WTF/bmalloc, Jul 25 → Aug 2 2026). ### Highlights - `29ceb3c03de3` Remove 32-bit JSValues (JSVALUE32_64 and `CPU(NEEDS_ALIGNED_ACCESS)` deleted). - `857bd4334690` Remove ARMv7 JIT support (ARMv7 is CLoop-only now; drops remaining 32-bit/x86 JIT refs). - `232cebabc1f3` Remove big-endian support and platforms without unaligned loads/stores (WTF + JSC). - `6eaa5ac1f65d` Remove 32-bit libpas support. - `bfb1b1183bc2` Remove the B3/Air graph-coloring register allocator (greedy is the only allocator now). - `0d0080ea539d` Enable WebAssembly Memory64 by default (+ Table64/SIMD follow-ups). - `f2f2c2ddf637` Remove `StringRecursionChecker`; cyclic `toString`/`join` now throws RangeError via stack check (spec-correct). - `319f94b3db4a` Enable `Iterator.prototype.includes()` by default. - `90b2ecf79ae3` `hostResolveImportedModule` now honors import-attribute `type` (module loader behavior change). - `f5716f6401ed` Add `preserve_most` calling convention to fastMalloc APIs on ARM64 (perf + ABI of WTF alloc entry points). ### JavaScriptCore **Runtime / builtins** - `f2f2c2ddf637` Remove StringRecursionChecker; rely on stack-overflow checks. - `cd91e7f128dd` Add fast flag for `ToPrimitive(Object)` calls in runtime. - `173a0bd6d937` Use `defaultToPrimitiveFastAndNonObservable` in `JSObject::toString`. - `960adeccefcd` Fast operation for `Array#shift`. - `92c6650c7947` Add `JSArrayIterator::next` C++ helper. - `cb1c48b3e95f` Extend `Array.from()` Set fast path to `set.keys()/.values()`. - `4a2e724d6789` Fix: `Array.from(set.keys()/.values())` fast path ignored `Symbol.iterator` overrides. - `73e4c589c1e6` Extend `StringSplitCache` to RegExp separators. - `656d3c36830f` / `1d355c27ea88` 8-byte SWAR fast paths in `JSON.stringify` string copy (same-type & upconvert). - `9f9370cc729f` Fix JSON.stringify regression around `toJSON` check. - `2eb77e9c9473` BigInt: implement Crandall reduction. - `39b1bb9cfc85` BigInt: deploy Comba multiplication more broadly. - `319f94b3db4a` Enable `Iterator.prototype.includes()`. - `0731b27c1b60` `Iterator.zip`: use null-prototype objects for options/underlying iterator. - `90b2ecf79ae3` `hostResolveImportedModule` respects module request import-attribute `type`. - `4f54300b848a` Collect diagnostics when `getDirect` returns zero JSValue in `llint_slow_path_get_by_id`. **Parser / bytecompiler** - `c2beca7a439f` Lexer: scan integer tokens in a single pass. - `72ea806faa21` Use overflow-safe range when choosing a switch jump table. **LLInt / DFG / FTL / B3** - `29ceb3c03de3` Remove 32-bit JSValues. - `857bd4334690` Remove ARMv7 JIT support. - `bfb1b1183bc2` Remove B3/Air graph-coloring register allocator. - `68cde6ba2ad3` Make IRO (Air register allocation) faster. - `83540481435f` DFG: allocate `BasicBlock::intersectionOfPastValuesAtHead` only for OSR-entry targets. - `1566615170ec` DFG fix: `EnumeratorNextUpdateIndexAndMode` must require original array structure for `InBoundsSaneChain`. - `e759fa9dd063` LLInt: inline hot path of `op_enter`. - `9610c2113b45` offlineasm: emit ARM64 register-offset addressing for BaseIndex operands. - `4ebed2479144` Speed up `addSortedRange` via binary search. - `1c006b0b0f62` Fix regex `setLastIndex` on 32-bit. **WebAssembly** - `0d0080ea539d` Enable Memory64 feature flag. - `15aa6fad53e3` Memory64: SIMD support. - `bf0425598904` Memory64: expand declared memory limits. - `862994e2cc37` Memory64: validate table import address-type match. - `184ee4c654bd` Memory64: Table64 in OMG tier. - `d202bedc5ff6` Memory64: Table64 in BBQ tier. - `bf6512f84f7d` Support `WebAssembly.Exception` `options.traceStack` (+ `stack` getter, ctor length = 2). - `24527bbb9ac8` Optimize Wasm JITCallee publication (lock splitting, icache barrier rework). - `1803d6109d98` Speed up `WebAssembly.Table` construction. - `d434a41411a3` BBQ: optimize `br_table` for consecutive same-target runs. - `51d3dbaa278e` IPInt: add `DEFINE_IPINT_THUNK_FOR_ENTRY`. - `244cd98f7986` Fix `generateWasmOpsHeader.py` under non-UTF-8 locales. **Yarr / RegExp** - `581f1d958329` Start end-anchored fixed-size regexps at the only possible position. - `a458a6c1f0a7` v-mode class-set op loop: stop early when no more output possible. - `7c5dbbcba110` Extend `ParenthesesSubpatternTerminal`. - `e1def8f4e5fd` Don't save sibling/ancestor-sibling frame slots for `ParenContext`. - `1e43057f135a` Extend first-character filter further. - `54916608d7d6` Fix non-BMP advance latch;

Removes every function-long `let x = unsafe { &mut * };` reborrow from the Rust codebase (~370 sites under any binding name, census now 0) and adds a source lint (`test/internal/source-lints/fn-long-mut-reborrow.test.ts`, runs on every Rust PR) so the shape cannot come back. The line asserts exclusive access for the whole function on objects whose callbacks re-enter them through their own accessors — Stacked/Tree Borrows UB and an LLVM `noalias` miscompile hazard. Where it was covering real re-entrancy, the type is fixed instead of the call site: | Fix shape | Applied to | |---|---| | `&self`-only API over `Cell`/`JsCell` state | `SendQueue`, `RequestContext`, `FileResponseStream`, `MultiPartUpload`, `UpgradedDuplex`, `SSLWrapper`, `WindowsNamedPipe`, `PathWatcher`, `Channel`, GC controller | | Raw `*mut Self` entries (callback may free the object; dispatch runs with no receiver protector) | `PipeReader` `read`/`on_poll`/`done`/`on_error`/`register_poll`/`stop_for_max_buffer`, `DuplexUpgradeContext` `on_*`, `ProxyTunnel::shutdown` | | Allocation-root pointer (`root: Cell<*mut Self>`) so pool/heap release never deallocates through a `&self`-derived tag | `SendQueue`, `Channel`, `WindowsNamedPipe`, `RequestContext` (request-pool `put`) | | Move ownership out before dispatch instead of aliasing across re-entrant JS | `MultiPartUpload` full-buffer part transfer | Supporting changes: `BackRef`/`ParentRef` gain a `Shared`/`Mut` write-provenance marker (writing through a `&T`-born backref is now a type error); `bun_event_loop::AnyTask` (`*mut c_void` + fn pointer) is deleted for typed `Taskable` tags; the `ErasedJsError` re-export alias is deleted; the cron register/remove job scaffolding is deduplicated via `CronJobBase` defaults. Deliberate behavior changes: IPC decode loops no longer hold a buffer borrow across user JS; subprocess buffered output is no longer re-delivered after a streaming drain (fixes an output-doubling bug this PR introduced mid-flight and CI caught); the test coordinator no longer drops a `Channel`/`Process` from inside that object's own callback. Out of scope, tracked follow-ups: `uv::StreamReader`'s `&mut Self` methods, `PipeWriter`'s `LaunderedSelf` impls, the remaining `&mut self` wrappers on `PosixBufferedReader` (`close`/`finish`/`start`/`watch`), and the test coordinator's `ChannelOwner::on_channel_frame` chain (`on_frame`/`assign_work` under a protected `&mut Worker`; `bail_out`'s comment documents the reachability) — all pre-existing parent-chain receivers, documented at the sites. ### How did you verify your code works? `bun run rust:check-all` (10/10 targets incl. Windows), `bun run rust:clippy` (clean), `bun run rust:miri -p bun_ptr` (18/18), the new source lint at census 0. Debug build driven end to end: IPC round trips (20k messages + disconnect), `Bun.serve` bodies/`Bun.file`/streaming/abort/burst (104-test serve-file suite), TLS-over-duplex (62 tests incl. close-UAF), S3 multipart, subprocess `maxBuffer` overflow, cron register/validate, server finalize-during-shutdown. Benchmarked CI builds of this head vs its `main` merge-base (same WebKit/mimalloc) on a 64-core Linux box: HTTP hello/echo, IPC, spawn, fs streams, startup all within the measured ±1% noise floor; anonymous/private-dirty RSS identical (3,444 kB both arms). --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- src/ast/new_store.rs | 6 +- src/bun_alloc/lib.rs | 30 +- src/bun_core/lib.rs | 6 +- src/bundler/Graph.rs | 6 +- src/bundler/LinkerContext.rs | 33 +- src/bundler/ParseTask.rs | 13 +- src/bundler/ServerComponentParseTask.rs | 2 +- src/bundler/ThreadPool.rs | 120 +- src/bundler/bundle_v2.rs | 123 +- .../generateChunksInParallel.rs | 5 +- src/codegen/generate-js2native.ts | 2 +- src/event_loop/AnyEventLoop.rs | 31 +- src/event_loop/AnyTask.rs | 69 -

Fixes #36832. `Bun.build({ splitting: true })` on a tree with chained `sideEffects: false` barrel packages (e.g. `@sentry/node-core` re-exporting `@sentry/core`) produced non-deterministic output, and in the unlucky parse order silently dropped modules: the build reported `success: true` while the emitted chunks referenced symbols no chunk declares, failing at boot with ``` SyntaxError: Exported binding 'tK' needs to refer to a top-level declared variable. ``` ### Cause Barrel optimization defers a barrel's unused re-export records at parse time and un-defers them later as requests for the names arrive (`scheduleBarrelDeferredImports`). Two of those request paths depended on parse-completion order: 1. A namespace request (`import * as ns from 'pkg-a'`) arriving after the barrel was parsed only un-deferred the barrel's own records. The names the barrel re-exports from an inner barrel (`export { beta } from 'pkg-b'`) were never requested from `pkg-b` when `pkg-b` had already been parsed with a partial request set. `pkg-b`'s records stayed deferred, the module bodies were dropped from the output, and the namespace object still referenced their symbols. This is the dropped-module case in the issue: the same 31 `@sentry/core` modules missing, 18 orphaned minified bindings. 2. `export * from` targets are meant to be exempt from deferral (the `IS_EXPORT_STAR_TARGET` check in `applyBarrelOptimization`), but the flag only lands if the star exporter parses before the target. This is what flapped the chunk graph (25 vs 32 chunks for identical input). ### Fix In `src/bundler/barrel_imports.rs`: - The BFS star branch now resolves un-deferred records inline and propagates the request onward: each re-exported name is requested from the module it comes from (by its original alias); namespace re-exports and `export *` targets are requested as full-namespace. - Star items mark a barrel as fully requested at most once, so the new propagation terminates on `export *` cycles. - `export * from` targets are recorded as fully requested when the star exporter is processed, making the deferral decision independent of parse order (same outcome the `IS_EXPORT_STAR_TARGET` flag produces when the exporter happens to parse first). ### Verification On the reporter's repro (https://github.com/Karavil/bun-splitting-orphaned-exports), the unfixed build produced three distinct outputs across runs (25-chunk good, 32-chunk variant, 25-chunk bad with 12 unlinkable chunks, ~2-4% of runs on a 16-core box). With the fix, output is byte-identical across every run, all chunks link when re-bundled individually, and the bundle boots. New test `barrel/NamespaceImportUndefersChainedBarrels` reconstructs the bad parse order deterministically: the file holding `import * as ns` is large enough that the small barrel files always parse (and defer) first. It fails on the unfixed build every time (module body missing from output, boot fails) and passes with the fix. Existing barrel, splitting, and edgecase bundler suites pass. --- **[review]** gate passed · iteration 1 · 2 files touched

**root cause** · written by the author bot The bundler's barrel import deferral failed to propagate namespace requests through chained barrel re-exports, and `export * from` targets were only marked fully requested when the exporter parsed before the target, making module inclusion dependent on the non-deterministic parallel parse order. When an unfavorable order occurred, deferred modules were never scheduled and were silently dropped from the output while other chunks still referenced their minified exports. The fix propagates full-namespace and aliased requests through both named and star re-exports during the BFS and seeds expor… --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- src/bundler/barrel_imports.rs | 162 +++++++++++++++++++++++----- test/bundler/bundler_barrel.test.ts | 112 +++++++++++++++++++ 2 files changed, 250 insertions(+), 24 deletions(-) diff --git a/src/bundler/barrel_imports.rs b/src/bundler/barrel_imports.rs index 90d59d5bf52a..86cc210a5783 100644 --- a/src/bundler/barrel_imports.rs +++ b/src/bundler/barrel_imports.rs @@ -280,11 +280,11 @@ fn apply_barrel_optimization_impl( } /// Clear is_unused on a deferred barrel record.

Each symbol was verified with `rg -w src/ build/debug/codegen/` to have zero references outside its own definition, then confirmed by a full `bun bd` build and `bun run rust:check-all` across all 10 targets. ### `src/platform/darwin.rs` (whole file, 210 LOC) The entire file duplicates `bun_sys::darwin`: the `OSLog`/`Signpost`/`Interval` API and the `nocancel` extern block have zero callers. `bun_perf` (the only signpost consumer) imports `bun_sys::darwin::OSLog` and `bun_sys::darwin::os_log::signpost::*`. `bun_platform` is force-linked only for `linux.rs`'s `#[no_mangle]` export. Also drops the now-unused `bun_opaque`/`strum` deps from `bun_platform/Cargo.toml` and the stale doc comment in `src/sys/lib.rs` that pointed here. ### webcrypto C++ - `CryptoKeyHMAC::create` + const-ref ctor, `CryptoKeyAES::create` + const-ref ctor: never called; `generate`/`importRaw`/`importJwk` all construct via the rvalue ctor directly. - `JSCryptoKey::fromJS`: declared, never defined, never called. - `JSSubtleCrypto::toWrapped`: only reachable via `convert>`; no such call exists. - `OpenSSLCryptoUniquePtr.h`: `X509Ptr`/`BIOPtr` aliases (zero refs) and the `OPENSSL_VERSION_NUMBER >= 0x30000000L` block (BoringSSL defines `0x1010107f`, so it never compiles, and no code references `OsslParamBldPtr`/`OsslParamPtr`/`EVPKDFCtxPtr`/`EVPKDFPtr`). - `CommonCryptoDERUtilities.h`: `extraBytesNeededForEncodedLength` is only called from the same TU; header decl removed, made `static` in the .cpp. - `ScriptExecutionContext.h`: `wrapCryptoKey`/`unwrapCryptoKey` stubs plus the commented-out virtual decls; leftover from the earlier `SerializedCryptoKeyWrap` removal. ### sqlite / NodeVM C++ - `lazy_sqlite3.h`: `sqlite3_column_int` / `sqlite3_memory_used` / `sqlite3_prepare16_v3` typedef+var+define+dlsym lines (code uses `sqlite3_column_int64`, tracks memory via `sqlite_malloc_amount`, uses `sqlite3_prepare_v3`). - `SQLiteSingleton::schema_versions`: never read, never appended to. - `JSStatementSync::allowBareNamedParams`/`allowUnknownNamedParams`/`rowStructure` getters: members are accessed directly. - `DOMIsoSubspaces`/`DOMClientIsoSubspaces::m_*subspaceForJSSQLStatementConstructor`: `JSSQLStatementConstructor` lives in `JSFunction`'s subspace per the `static_assert` in `JSSQLStatement.h`. - `NodeVMGlobalObject::sigintReceived`: not virtual, never called; `SigintWatcher::signalAll` invokes `vm().notifyNeedTermination()` directly. - `NodeVMModuleRequest::specifier`/`importAttributes` getters: `toJS` reads `m_specifier`/`m_importAttributes` directly. ### Rust - `bun_ast::PartTag::{JsxImport, CjsImports, ReactFastRefresh}`: never assigned or compared. - `bun_ast::flags::JSXElement::HasAnyDynamic`: never inserted or tested. - `bun_ast::import_record::Tag::Tailwind`: last variant, never constructed or matched. - `bun_ast::BindingNodeList` type alias + its unused re-export in `bun_js_parser::parser`. - `bun_ast::StoreAstAllocHeap::reset`: callers invoke the free fn `store_ast_alloc_heap::reset()` directly. - `bun_jsc::JSPromise::reject_task`: sibling `resolve_task` has 4 callers, `reject_task` has zero. - `bun_jsc::JSRuntimeType::UNDEFINED`: only `NOTHING` is referenced. ### src/js - `readline.js`: unused `ObjectSetPrototypeOf` primordial destructure. - `repl.js`: unused `ArrayPrototypeSlice` primordial destructure. - `zlib.ts`: collapse redundant `ArrayBufferIsView` intermediate alias. ### Verification - `bun bd` builds clean - `bun run rust:check-all` passes all 10 targets (incl. `aarch64-apple-darwin` for the `bun_platform` change) - Smoke tests pass: `web-crypto.test.ts`, `sqlite.test.js`, `node-sqlite.test.ts`, `zlib.test.js`, `transpiler.test.js` - `test/internal/source-lints/dead-symbols-platform-webcrypto-sqlite-vm.test.ts` fails on main, passes on this branch ### Followups (not deleted; left for review) - `src/runtime/api/bun/h2/connection.rs:1731-1941` outbound-stream API (`begin_header_block`/`encode_header`/`send_header_block`/`send_data`/`send_push_promise` + transitively `SendWindow::{available,consume}`, `Coder::{take_pending_size_update,encode}`, `write_table_size_update`, ~215 LOC): only called from `#[cfg(test)]`. File carries `#![allow(dead_code)]` and was authored in #31584; likely intentional WIP scaffolding for migrating `h2_frame_parser`'s outbound path. - `src/jsc/bindings/webcrypto/*.idl` (29 files, ~1055 LOC): not processed by any build step (`scripts/glob-sources.ts` globs only `*.cpp`), but #34838 edited them recently so they may be maintained as documentation. - `src/jsc/ErrorCode.rs`: `Zig_ErrorCodeJSErrorObject` `#[no_mangle]` static with zero refs in any `.cpp`/`.h` (sibling `Zig_ErrorCodeParserError` is declared in `headers-handwritten.h`; this one is not). --- **[review]** gate passed · iteration 0 · 34 files touched

This tightens what each test asserts and wraps them in `describe.concurrent` since they share no state. ## Assertion changes 10 `expect()` calls, up from 8: - Check `stderr`/`stdout` before `exitCode` so failures print useful output. - Assert `stderr` is empty on both success paths (previously captured but never checked). - Happy path: compare the full stdout as a sorted line set instead of two substring checks, so an unexpected extra line or format change fails. This also subsumes the old `not.toContain("root test")` check. - `--if-present`: also assert nothing is emitted for the package that lacks the script. - Error path: also assert `stdout` is empty and include the script name in the expected error text. - `await using proc = Bun.spawn(...)` for cleanup. No tests removed or skipped. ## Timing Local `bun bd test` (debug+ASAN), 5 runs each: median 2.74s before, 2.22s after. debian-13 x64-asan CI lane: **11.99s** (build 88024) vs **11.06s** (build 88091, this PR). The three subprocesses are CPU-bound under ASAN so running them concurrently on the CI runner wins less than I initially expected; the assertion tightening is the main value here. --- **[stamp-90s]** gate passed · iteration 0 · 1 files touched

charset=UTF-8 Content-Transfer-Encoding: 8bit ### What `test/cli/install/config-version.test.ts` took ~10s on alpine 3.23 x64 in CI (build 88024). Most of that time was forking a verdaccio child process and polling it for up to 30 seconds before any test could run, with two of the three tests gated behind `test.skipIf(!registryCanServe)`, which silently reports them as passed when the poll loop gives up. ### Change All three tests cover the `configVersion` field in `bun.lock` and the linker selection it gates; neither depends on where packages come from. Replace the registry dependency with a local `file:` dependency (same pattern as `lockfile-version-2.test.ts` in the same directory), drop the verdaccio process and the 30s readiness poll entirely, and run the three independent installs under `describe.concurrent`. Assertions are tightened along the way: - The two previously skippable tests now always run. - `bun install` stdout is asserted via `normalizeBunSnapshot` inline snapshots before the exit code. - The indirect `.not.toContain("panic:")` check inherited from `runBunInstall` is gone. No tests are deleted or skipped; the lockfile inline snapshots and the `node_modules` layout checks are preserved. ### Why this is correct The `configVersion` field and the default linker decision are computed from whether the project is a workspace root and whether a lockfile already existed, independent of the dependency protocol. Running the same three scenarios with a `file:` dependency exercises the same code path in `src/install/` that writes `configVersion` and picks the linker; the only thing that changes in the lockfile snapshot is the `packages` entry shape (`["dep@file:dep", {}]` instead of the registry URL/sha line), which is not what these tests cover. Registry resolution itself is covered extensively elsewhere in `test/cli/install/`. ### Timing `bun bd test test/cli/install/config-version.test.ts`, best of three: | | before | after | | --- | --- | --- | | debug | 3.48s | 2.24s | | release | 970ms | 155ms | On alpine the verdaccio fork is considerably slower than locally (the file reports ~10s there), so the CI-side improvement should be larger than the local release ratio suggests. #33115 replaces verdaccio across the whole install suite with an in-process registry and also touches this file; this change is independent of that (the file no longer uses any registry at all) and can land on its own. --- **[stamp-90s]** gate passed · iteration 0 · 1 files touched

Bumps libuv to oven-sh/libuv#12 + oven-sh/libuv#13 (merged as `89ee3439` on the `bun` branch). On Windows, `uv_spawn` assigns each spawned child to libuv's global job object. If `AssignProcessToJobObject` failed with anything other than `ERROR_ACCESS_DENIED`, libuv called `uv_fatal_error`, which prints `AssignProcessToJobObject: (N) ...` and `abort()`s the whole process, observed as exit code `0x80000003` with `AssignProcessToJobObject: (6) The handle is invalid.` on stderr, uncatchable from JS. With oven-sh/libuv#12 that failure terminates the child and returns the translated error from `uv_spawn`, so `Bun.spawn` throws a normal `EBADF ... uv_spawn` error instead of the runtime dying. oven-sh/libuv#13 additionally closes the two handles `CreateProcessW` returned on both post-`CreateProcessW` failure paths (that one and the `ResumeThread` failure path for detached spawns), which otherwise leak one process handle and one thread handle per failed spawn. ### How did you verify your code works? Exercised both `done_created` paths on windows-x64 by IAT-hooking `AssignProcessToJobObject` and `ResumeThread` in the exe (libuv is statically linked, so its kernel32 calls resolve via the exe's import table) and spawning 200 times per path while sampling `GetProcessHandleCount`: | path | libuv#12 | libuv#13 | | --- | --- | --- | | `AssignProcessToJobObject` fail (non-detached) | handles +400 | +0 | | `ResumeThread` fail (detached, `CREATE_SUSPENDED`) | handles +400 | +0 | +400 over 200 iterations is exactly the two handles (`hProcess`, `hThread`) per failed spawn. In both cases the spawn throws `{ code: 'EBADF', syscall: 'uv_spawn' }` (the translated `ERROR_INVALID_HANDLE`, captured before the cleanup calls so it is not clobbered) and a subsequent normal spawn succeeds. --------- Co-authored-by: robobun <117481402+robobun@users.noreply.github.com> Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- scripts/build/deps/libuv.ts | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/scripts/build/deps/libuv.ts b/scripts/build/deps/libuv.ts index 27f624e8d21c..3ff7e346c9f0 100644 --- a/scripts/build/deps/libuv.ts +++ b/scripts/build/deps/libuv.ts @@ -14,8 +14,11 @@ import type { Dependency } from "../source.ts"; // fix, ConPTY uv_spawn, AppContainer pipe namespace (oven-sh/libuv#7), fs/tty // fixes (oven-sh/libuv#8), high-res poll timeouts (oven-sh/libuv#9), // FileModeInformation error return (oven-sh/libuv#10), error translation / -// propagation audit fixes (oven-sh/libuv#11).

Across the last 400 completed builds it accounts for 340 flaky-annotation entries. Signature from any recent main build (e.g. [88187](https://buildkite.com/bun/bun/builds/88187)): ``` Interrupted while still running: test/regression/issue/tty-reopen-after-stdin-eof.test.ts (245s) ... parallel bucket: retrying 1 failed and 0 unfinished file(s) one at a time --- [98/286] test/regression/issue/tty-reopen-after-stdin-eof.test.ts 2 pass / 0 fail ... [72.00ms] ``` The parallel batch idles for ~4 minutes waiting on this one file before the runner's idle timeout kills it. ## Cause The test wraps its child in `script(1)` to provide a PTY. Alpine images don't have `script`, so the test falls back to spawning `sh -c "echo ... | bun test.js"` directly and relying on the inherited `/dev/tty`. `bun test --parallel` spawns each worker in its own process group via `setpgid(0, 0)` (same session, no `setsid`). That puts the worker, and everything it spawns, in a **background** process group of the inherited controlling terminal. When the child script then calls `tty.ReadStream#setRawMode(true)`, the `tcsetattr()` inside `Bun__ttySetMode` is issued from a background pgrp, so the kernel delivers `SIGTTOU` and the process is **stopped** (not killed). The test hangs until the runner gives up. On the solo retry the test runs in the coordinator's (foreground) pgrp, so `tcsetattr()` succeeds. Other Linux lanes have `script`, which creates a fresh session+PTY, so they never hit the fallback. ## Repro ```python # with a controlling TTY present, `script` hidden from PATH, and >=2 files so # --parallel actually forks workers: bun test --parallel=2 test/regression/issue/06467.test.ts \ test/regression/issue/tty-reopen-after-stdin-eof.test.ts # -> hangs indefinitely after the first file ``` Standalone confirmation of the mechanism (python): ``` GRANDCHILD: opened /dev/tty fd=3 GRANDCHILD: tcgetattr ok CHILD: grandchild STOPPED by signal 22 (SIGTTOU=22) ``` ## Fix Replace the `script`/no-`script` branching with `Bun.spawn`'s inline `terminal:` option, which creates a PTY and runs `setsid()` + `ioctl(TIOCSCTTY)` in the child. The spawned `sh` is then always the foreground process group of its own controlling terminal, so the inner `setRawMode()` can never SIGTTOU regardless of where the test itself sits in the process tree. This also removes: - the dependency on an external `script` binary - the macOS-vs-Linux `script` argv differences - the macOS `^D\b\b` output munging - the "skip on ENXIO" fallback Net -91 lines. ## Verification ``` # before, Alpine-equivalent (script hidden, ctty present, --parallel) === TIMED OUT after 25s (HANG REPRODUCED) === # after, same scenario 3 pass / 0 fail ... [126.00ms] === DONE exit=0 in 0.1s === ``` Also verified the new test passes on macOS arm64 (via `Bun.Terminal`, no `^D` prefix). The assertions on `POS:undefined`/`START:undefined` still exercise the original #22591 regression. --- **no test proof** · iteration 0 · Platform-specific test-only change; deferring to CI. --- .../issue/tty-reopen-after-stdin-eof.test.ts | 213 +++++------------- 1 file changed, 61 insertions(+), 152 deletions(-) diff --git a/test/regression/issue/tty-reopen-after-stdin-eof.test.ts b/test/regression/issue/tty-reopen-after-stdin-eof.test.ts index 5019b4260ffd..09900c5792e5 100644 --- a/test/regression/issue/tty-reopen-after-stdin-eof.test.ts +++ b/test/regression/issue/tty-reopen-after-stdin-eof.test.ts @@ -1,44 +1,65 @@ import { expect, test } from "bun:test"; -import { bunEnv, bunExe, isWindows, normalizeBunSnapshot, tempDir } from "harness"; +import { bunEnv, bunExe, isWindows, tempDir } from "harness"; import { join } from "path"; +// Run `sh -c ` inside a fresh PTY session and return the child's output +// as LF-normalized lines.

v1.5.1

The prepare step (installing packages etc.) normally runs on every build. With cache-after-prepare: true, the action shuts the VM down cleanly after prepare has finished, caches the prepared VM image, and boots the VM again before run. Later runs with the same prepare script restore the prepared image, skip prepare entirely, and start directly at run

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Repro A `Bun.serve` handler returns `new Response(Bun.file(path).slice(0, n))` for a file larger than `n`, and the second `read()` on that file fails (transient disk/NFS/FUSE error). Under ASAN: ``` AddressSanitizer: heap-use-after-free READ of size 4 bun_ptr::ScopedRef::new src/ptr/ref_count.rs:931 bun_runtime::dispatch::run_task src/runtime/dispatch.rs:307 freed by: ScopedRef::drop FileResponseStream::start src/runtime/server/FileResponseStream.rs:247 RequestContext::do_sendfile src/runtime/server/RequestContext.rs:1944 ``` Reproduced with a ptrace supervisor that injects `EIO` on the second `read()` of the served file (Bun's `read()` is a raw syscall via rustix, so LD_PRELOAD can't intercept it). ## Cause `PosixBufferedReader::read_with_fn`'s error arm first flushes buffered bytes through `on_read_chunk(.., Progress)`, then calls `on_reader_error`. When the buffered chunk satisfies `max_size`, `on_read_chunk` enqueues a `FileResponseStreamEof` task and ends the response. The old SAFETY comment assumed the in-flight read ref (`READ_REF_HELD`) keeps the stream alive until that task runs, but `on_reader_error` calls `take_read_ref()` and `finish()` in the same frame, dropping that ref and the owner ref. Back in `start()` the scope guard drops the last ref and frees the `Box` while the task is still queued. ## Fix The task takes its own ref at enqueue time; the `FileResponseStreamEof` dispatch arm adopts it instead of bumping a fresh one. `on_reader_done`/`finish()` are already idempotent, so a task that runs after the error path has already finished the stream is a no-op. ## Verification ``` # without fix (git stash -- src/): ASAN heap-use-after-free, exit 1 # with fix: bun bd test test/js/bun/http/serve-file-slice-read-error.test.ts (pass) Bun.serve Bun.file().slice() survives a read() error after the slice is satisfied [406.94ms] ``` `test/js/bun/http/bun-serve-file.test.ts` (104 tests) passes unchanged. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

The reparse-point branch dropped the sync flag entirely, so a `NOFOLLOW` open would return an asynchronous file object. Our synchronous `ReadFile`/`WriteFile` callers pass a null `hEvent`/`lpOverlapped`, which is undefined on an async handle. The directory-open path just above (`open_dir_at_windows_nt_path`) already does this correctly: it computes `open_reparse` as `FILE_OPEN_REPARSE_POINT` or `0` and ORs it into the options alongside `FILE_SYNCHRONOUS_IO_NONALERT`. #### Fix OR `FILE_OPEN_REPARSE_POINT` into `blocking_flag` rather than replacing it. #### Why no regression test There is no JS-reachable path that issues a read or write against a handle from this branch: - `fs.openSync`/`fs.open` on Windows route through `sys_uv::open` → `uv_fs_open` (node_fs.rs:6044, sys_uv.rs:84), never `openat_windows_impl`. The JS-side flag value is also translated by `bun_libuv_sys::O::to_bun_o` (types.rs:1619), which has no `NOFOLLOW` mapping, so the bit cannot be passed in from JS. - `fs.readSync`/`fs.writeSync` on Windows route through `uv_fs_read`/`uv_fs_write` (sys_uv.rs:584), not raw `ReadFile`/`WriteFile`. - The `fs.cp` `O::NOFOLLOW` opens are gated to Linux/Android (node_fs.rs:8666) and FreeBSD (node_fs.rs:8834). - Tarball extraction zeroes `NOFOLLOW` under `cfg!(windows)`. - The one live Windows caller of the file branch with `O::NOFOLLOW` is `lstatat` (sys/lib.rs:862), which only calls `fstat` then `close` on the handle; `NtQueryInformationFile` does not depend on the sync bit, so the defect is not observable there. This is a latent code-inspection fix with no fail-before test possible today.

The native binlink optimization (link a wrapper package's bin straight at the matching platform-specific optionalDependency's binary and skip the wrapper's postinstall) returned early on Windows because the redirect couldn't resolve `.exe` layouts. So on Windows `@anthropic-ai/claude-code`'s bin stayed pointed at `bin/claude.exe`, which the package ships as a text placeholder stub its postinstall is meant to overwrite. Whenever that postinstall doesn't run, Windows tries to execute the text file and shows "Unsupported 16-Bit Application" (a headerless `.exe` is classified as a legacy DOS binary). `resolve_bin_target` now also probes `/` (`claude.exe` at the root of `claude-code-win32-x64`) and `/.exe` (esbuild's `esbuild.exe` at the root of `@esbuild/win32-x64`), and the WIN32 early return in `get_native_binlink_replacement_package_id` is gone, so Windows takes the same redirect + script-skip path as POSIX. The `.exe` probe is not compile-time gated, so cross-installing with `--os win32` on a POSIX host resolves the same file a native Windows install would. The binlink test suite now runs on Windows: the realpath-on-symlink assertions are replaced with a helper that reads the `.bunx` shim metadata's UTF-16LE target path, and the spawned `.bin/` paths pick up the `.exe` suffix. The one remaining `skipIf(isWindows)` is the resolved-containment test at the bottom of the file, which guards against the POSIX bin linker chmod'ing/rewriting a file outside the package via an in-package symlink; the Windows shim never touches the target file and the check itself is `#[cfg(not(windows))]` in `link_bin_or_create_shim`. ### How did you verify your code works? `bun bd test test/cli/install/bun-install-native-binlink.test.ts`: 16 pass on Linux, 15 pass / 1 skip on Windows. The altpath fixture now has three versions, one per probe path; with `src/` reverted to `main` the two new-probe versions fail while the rest of the suite passes. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

is written (#36859) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #26508. ## Repro Next.js 16's [`app-render-scheduling.ts`](https://github.com/vercel/next.js/blob/31b62520366aefef9d6800cd519157a16f958052/packages/next/src/server/app-render/app-render-scheduling.ts#L29-L49) creates two `setTimeout(fn)` calls and then writes `t2._idleStart = t1._idleStart` so both timers share a deadline and fire in the same event-loop turn, before any `setImmediate` scheduled from `t1`'s callback. ```js let immediateRan = false; const t1 = setTimeout(() => { setImmediate(() => { immediateRan = true; }); }); // force the monotonic clock past a millisecond boundary { const s = performance.now(); while (performance.now() - s < 2) {} } const t2 = setTimeout(() => { if (immediateRan) process.exit(1); }); t2._idleStart = t1._idleStart; ``` 100 iterations: **Node** 0 failures, **Bun (before)** 94 failures, **Bun (after)** 0 failures. ## Cause `TimeoutObject::set_idle_start` (added in #26021) only cached the JS value. It never updated the `EventLoopTimer.next` deadline in the native timer heap, so the assignment had no scheduling effect and `t2` could fire in a later turn after the `setImmediate`. ## Fix `TimerObjectInternals::set_idle_start` recomputes the deadline as `Timespec::EPOCH.add_ms(idle_start_ms + interval)` and calls `All::update()` to remove and re-insert the timer. The heap comparison in `EventLoopTimer::less` already collapses sub-millisecond precision for JS timers and uses the insertion epoch as tiebreak, so after `t2._idleStart = t1._idleStart` the two timers compare equal on deadline and `t1` still fires first (lower epoch). The setter is a no-op for cleared timers, non-ACTIVE timers, and non-finite values; the JS value is always cached regardless. ## Verification New `_idleStart` describe in `test/js/node/timers/node-timers.test.ts`: - "reschedules the timer when written (Next.js pattern)": spawns a subprocess running 50 iterations of the busy-loop repro, asserting the immediate never runs between `t1` and `t2` and order is always `t1,t2`. Fails on `USE_SYSTEM_BUN=1` ("FAIL: immediate ran before t2 on iteration 0"), passes with `bun bd test`. - "ignores non-finite values and cleared timers": edge-case coverage for string/NaN/Infinity/post-clear writes. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

With [`--timings`](#balancing-with---timings) the chunks are cut by recorded duration instead of file count, each worker starts its slowest file first, and an idle worker steals the slowest not-yet-started file from whichever chunk has the most time left. + +### Every file is isolated (unless you opt out) + +`--parallel` implies [`--isolate`](#--isolate): each file runs in a fresh global object even when two files land on the same worker. Tests that pass with `--parallel` don't depend on state leaked by an earlier file. + +`--parallel --no-isolate` turns that off: each worker keeps a single global and module registry for all the files it is handed, exactly like a serial `bun test` does for the whole suite. Imports (and `--preload` modules) are evaluated once per worker instead of once per file, which is the fastest way to run a large suite of small files — at the price that a file can observe whatever an earlier file on the same worker left behind. Preload-level `beforeAll`/`afterAll` hooks still wrap every file, since a worker never knows which file is its last. + +### Worker environment + +Each worker gets `BUN_TEST_WORKER_ID` and `JEST_WORKER_ID` set to its 1-based index, so tests can pick a distinct database, port range, or temp directory per worker: + +```ts title="db.test.ts" icon="/icons/typescript.svg" +const dbName = `app_test_${process.env.BUN_TEST_WORKER_ID ?? "1"}`; +``` + +Flags that affect how tests execute (`--timeout`, `--preload`, `--define`, `--coverage`, `--update-snapshots`, `-t`, `--retry`, `--rerun-each`, `--concurrent`, `--randomize`/`--seed`, …) are forwarded to workers. `--bail` is handled by the coordinator at file granularity: once the failure threshold is reached no new files are started, but files already running finish. + +Coverage, JUnit XML and snapshot writes are merged by the coordinator, so `--parallel --coverage --reporter=junit --reporter-outfile=junit.xml` produces one report. + +If a worker crashes (a native addon segfaults, or a test calls `process.exit`) the file it was running is reported as failed and a replacement worker picks up the remaining files. A crash from a fatal signal aborts the whole run so it can't be masked by later passing files. + +### When `--parallel` helps, and when it doesn't + +`--parallel` pays off when the suite is dominated by test execution — I/O waits, real computation, subprocesses, many files. It costs something too: every file re-evaluates its imports in a fresh global (see [`--isolate`](#--isolate)), and each worker is a separate process with its own JIT warm-up. For a suite of very fast files that all import the same large module graph, plain `bun test` (one process, one shared module registry) can be faster. Try both; the numbers are printed at the end of every run. + +## `--isolate` + +```sh terminal icon="terminal" +bun test --isolate +``` + +Runs each test file in a fresh JavaScript global object inside the same process. Between files Bun: + +- creates a new `globalThis` (so properties a file stuck on `globalThis`, patched built-ins, and module-level state are gone), +- clears the ESM and CommonJS module registries (every file re-evaluates its imports), +- closes servers, sockets, file watchers and subprocesses the file left open, cancels its timers, and restores fake timers, +- re-runs `--preload` scripts in the new global. + +This is how Jest and Vitest behave by default. It makes "passes alone, fails in the full suite" bugs go away at the cost of re-evaluating imports per file. + +To keep that cost low, transpiled source and bytecode are cached at the process level and shared across globals: the second file to import a module skips reading, transpiling and parsing it and goes straight to evaluation. Only the module's top-level code runs again. + +Without `--isolate` (the default), all files share one global and one module registry. That is the fastest mode and is fine for suites whose files don't leak state into each other. + +## Concurrent tests within a file + +`--parallel` spreads _files_ across cores. Within one file tests still run one at a time unless you opt in to concurrency, which lets `async` tests overlap while one is waiting on I/O: + +```ts title="api.test.ts" icon="/icons/typescript.svg" +import { test, expect } from "bun:test"; + +test.concurrent("GET /users", async () => { + const res = await fetch(`${baseUrl}/users`); + expect(res.status).toBe(200); +}); + +test.concurrent("GET /posts", async () => { + const res = await fetch(`${baseUrl}/posts`); + expect(res.status).toBe(200); +}); + +// runs after the concurrent group, alone +test.serial("resets the database", async () => { + await resetDb(); +}); +``` + +- `test.concurrent(...)` / `describe.concurrent(...)` mark individual tests or whole groups. +- `--concurrent` treats every test as concurrent; `test.serial` opts back out. +- `--max-concurrency=N` caps how many run at once (default 20). +- [`concurrentTestGlob`](/test/configuration#concurrenttestglob) in `bunfig.toml` turns it on for matching files only. + +Concurrent tests share a thread and a global; this is cooperative concurrency for I/O-bound tests, not extra CPU cores. `expect.assertions()` and other per-test global state need care under concurrency — see [Concurrent test execution](/test/index#concurrent-test-execution). + +## Splitting a suite across CI machines with `--shard` + +```sh terminal icon="terminal" +bun test --shard=1/3 # machine 1 +bun test --shard=2/3 # machine 2 +bun test --shard=3/3 # machine 3 +``` + +Every machine sorts the discovered test files by path and takes a deterministic slice, so together the shards cover each file exactly once with no coordination.

Give `bun test` a record of how long each file takes and it will cut shards by total time instead, keeping neighbouring files (which share imports) together: + +```sh terminal icon="terminal" +# Record durations (any run can do this; --parallel is fine) +bun test --timings=.bun-test-timings.json --update-timings + +# Use them +bun test --shard=2/8 --parallel --timings=.bun-test-timings.json +``` + +The file is plain JSON, slowest first, so it doubles as a "what's slow" report: + +```json title=".bun-test-timings.json" icon="file-json" +{ + "version": 1, + "files": { + "test/integration/build.test.ts": 41234, + "test/db/migrate.test.ts": 9876, + "src/router.test.ts": 112 + } +} +``` + +- Paths are relative to the project root; values are wall-clock milliseconds for the whole file. +- Without `--shard`, `--update-timings` merges into what it read, so re-running part of the suite locally refreshes those entries and keeps the rest. Entries for files that no longer exist are left alone; delete the file to start over. +- With `--shard`, `--update-timings` writes **only the files that shard ran** — see below. +- Files with no entry are assumed to take the median time when cutting shards, and are started first under `--parallel`. +- With `--timings`, `--parallel` also uses the durations: worker chunks are cut by time and each worker starts its slowest file first. + +#### One timings file per shard + +`--timings` can be passed more than once; the files are read as one table (paths that don't exist yet are skipped), and `--update-timings` writes to the **first** path.

Bun shares transpiled source and bytecode across those globals so nothing is re-parsed, but module evaluation and JIT warm-up still repeat per file — which is why, on this shape, one shared global (`bun test`) beats sixteen isolated workers, and sixteen shared globals (`--parallel --no-isolate`) beat both. diff --git a/src/jsc/bindings/ZigGlobalObject.cpp b/src/jsc/bindings/ZigGlobalObject.cpp index a3aa700f0fbe..5f9d4904c266 100644 --- a/src/jsc/bindings/ZigGlobalObject.cpp +++ b/src/jsc/bindings/ZigGlobalObject.cpp @@ -284,11 +284,11 @@ extern "C" void Bun__REPRL__registerFuzzilliFunctions(Zig::GlobalObject*); extern "C" long Bun__crashHandlerFromJSCFrame(void*, void*, void*, void*); #endif -extern "C" void JSCInitialize(const char* envp[], size_t envc, void (*onCrash)(const char* ptr, size_t length), bool evalMode, bool oneShotStartup) +extern "C" void JSCInitialize(const char* envp[], size_t envc, void (*onCrash)(const char* ptr, size_t length), bool evalMode, bool oneShotStartup, bool shortLivedGlobals) { static std::once_flag jsc_init_flag; // NOLINTBEGIN - std::call_once(jsc_init_flag, [evalMode, oneShotStartup, envp, envc, onCrash]() { + std::call_once(jsc_init_flag, [evalMode, oneShotStartup, shortLivedGlobals, envp, envc, onCrash]() { JSC::Config::enableRestrictedOptions(); std::set_terminate([]() { Zig__GlobalObject__onCrash(); }); @@ -352,6 +352,11 @@ extern "C" void JSCInitialize(const char* envp[], size_t envc, void (*onCrash)(c JSC::Options::numberOfGCMarkers() = 1; } + // `bun test --isolate`: FTL code dies with each file's global, so only tier up code hot enough to pay that back within one file. + if (shortLivedGlobals) { + JSC::Options::thresholdForFTLOptimizeAfterWarmUp() = 1000000; + } + if (envc > 0) [[likely]] { auto envc_copy = envc; while (envc_copy--) { diff --git a/src/jsc/lib.rs b/src/jsc/lib.rs index f919e65d970a..e57d39e81823 100644 --- a/src/jsc/lib.rs +++ b/src/jsc/lib.rs @@ -523,6 +523,11 @@ pub mod work_task; /// Binding for JSCInitialize in ZigGlobalObject.cpp pub fn initialize(eval_mode: bool) { + initialize_with(eval_mode, false); +} + +/// `short_lived_globals`: `bun test --isolate`/`--parallel`, where each file gets a fresh global and per-global JIT code is discarded with it. +pub fn initialize_with(eval_mode: bool, short_lived_globals: bool) { // The counter lives in `bun_core` so this crate doesn't depend on // `bun_analytics`. bun_core::analytics::Features::jsc_inc(); @@ -541,6 +546,7 @@ pub fn initialize(eval_mode: bool) { on_jsc_invalid_env_var, eval_mode, one_shot, + short_lived_globals, ) }; } @@ -1920,6 +1926,7 @@ unsafe extern "C" { cb: extern "C" fn(name: *const u8, len: usize), eval_mode: bool, one_shot_startup: bool, + short_lived_globals: bool, ); } diff --git a/src/options_types/context.rs b/src/options_types/context.rs index ad3550028311..32068217f6fb 100644 --- a/src/options_types/context.rs +++ b/src/options_types/context.rs @@ -438,6 +438,10 @@ pub struct TestOptions { /// and only every Nth file (starting from M-1) is run. index is /// 1-based; both are validated at parse time so `1 <= index <= count`. pub shard: Option, + /// `bun test --timings=...`: per-file durations (ms), merged across files; the first is where `--update-timings` writes. + pub timings_files: Vec>, + /// `bun test --update-timings`: merge this run's measured per-file durations into `timings_file`. + pub update_timings: bool, pub reporters: Reporters, pub reporter_outfile: Option>, @@ -502,6 +506,8 @@ impl Default for TestOptions { test_worker: false, changed: None, shard: None, + timings_files: Vec::new(), + update_timings: false, reporters: Reporters::default(), reporter_outfile: None, } diff --git a/src/runtime/cli/Arguments.rs b/src/runtime/cli/Arguments.rs index 0a70ab0db1ee..6dec4f9c9377 100644 --- a/src/runtime/cli/Arguments.rs +++ b/src/runtime/cli/Arguments.rs @@ -597,6 +597,9 @@ pub(crate) const TEST_ONLY_PARAMS: &[ParamType] = &[ parse_param!( "--isolate Run each test file in a fresh global object.

Any other errno, including `EACCES`/`EPERM` (what FUSE returns for unsupported hard links), aborts the package install. The same EXDEV-only check exists in the isolated linker's two hardlink fallback sites. ### Fix Treat `EACCES` and `EPERM` from `linkat` like `EXDEV` and fall back to the copyfile backend, in both the hoisted installer (`install_with_hardlink`) and the isolated installer. A genuine destination permission error is not masked, since the copy attempt then fails with the same errno. ### Verification New test `test/cli/install/bun-install-hardlink-fallback.test.ts` compiles an `LD_PRELOAD` shim that fails `linkat` with `EACCES` or `EPERM` and asserts `bun install` succeeds with both the hoisted and isolated linkers (Linux glibc only; bun-musl is statically linked so the shim cannot intercept). `nlink === 1` on the installed files proves the copy fallback ran rather than a real hardlink. All four cases fail on current bun and pass with this change. --- **no test proof** · iteration 2 · Platform-specific test(s) that do not run on this machine.

Follow-up to #35263 (which took the file from 80s to ~28s). ## Why it was still slow Each full `bun build --compile` test clones the ~200 MB debug `bun.exe` and then rewrites it via rescle, so disk I/O dominates wall-clock. The suite launched 26 of those under `describe.concurrent`, but `bun:test` caps concurrency at 20, so the old layout also spilled six full compiles into a second wave that could only start once the first wave drained. ## How Fold assertions onto fewer compiles instead of dropping coverage: - Assert the default **CUI** subsystem on the "all metadata via CLI" binary and the post-rescle **GUI** subsystem on the "metadata with --windows-hide-console" binary, dropping the two standalone subsystem compiles that built the same flag combinations. - Give each surrounding test a distinct `--windows-version` arity and assert the normalized `ProductVersion`/`FileVersion` there, so the six-entry version-format `test.each` collapses to a single "--windows-version alone" build. The mapping is documented in-file: | input | normalized | asserted by | | --- | --- | --- | | `1` | `1.0.0.0` | Version string formats > --windows-version alone | | `1.2` | `1.2.0.0` | Bun.build() API > partial metadata | | `1.2.3` | `1.2.3.0` | Combined > metadata with --windows-hide-console | | `1.2.3.4` | `1.2.3.4` | CLI flags > all metadata flags via CLI | | `10.20.30.40` | `10.20.30.40` | CLI flags > partial metadata flags | | `65535.65535.65535.65535` | unchanged | Bun.build() API > all metadata (u16 max, pairs with the invalid `65536.0.0.0` case) | - Merge the "special characters" and "unicode" edge cases into one build: every `--windows-*` string flows through the same `to_utf16_alloc_for_real` → rescle `SetVersionString` wide-string path, so one binary that mixes Latin-1 symbols, ASCII punctuation, BMP CJK and surrogate-pair emoji across the four fields covers the same encoding surface. - Drive the five **invalid**-version cases through `--compile-executable-path` with the existing ~128 KiB `minimalPE64Template()`. `InvalidVersionFormat` is raised by the Rust validator in `bun_sys::windows::rescle::set_windows_metadata` before `rescle__setWindowsMetadata` opens the output, so the template never needs a `.rsrc` section for these. Net: 26 full-bun clones → 13 (plus 5 tiny-template builds), and all 22 tests now fit inside the 20-slot concurrency window. ## Stronger assertions - "relative outdir with compile" now reads back `ProductName`/`OriginalFilename` instead of only checking the file exists (and cleans the output up). - "empty strings in metadata" now asserts `OriginalFilename` was cleared, proving the rescle pass actually ran with empty field values. - "unicode and special characters" now asserts every field round-trips exactly (was `toContain` on two of four fields, nothing on the others). - "partial metadata via Bun.build()" and "all metadata via Bun.build()" now also assert `FileVersion` and `OriginalFilename`. - "metadata with --windows-hide-console" additionally asserts the PE `Subsystem` stayed GUI after rescle. ## Timings (Windows Server 2019 x64, 16 vCPU, `bun bd test --timeout=90000`) | | run 1 | run 2 | run 3 | run 4 | | --- | --- | --- | --- | --- | | before | 24.50s | 25.28s | | | | after | 15.28s | 15.39s | 15.43s | 15.84s | ~38% faster. All 22 tests pass across four consecutive debug runs on Windows; on Linux the Windows-gated describes still skip and the two cross-platform PE-checksum tests at the bottom of the file are unchanged.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## What `test/bundler/compile-asset-bunfs.test.ts` was running six full `bun build --compile` invocations concurrently. Under debug+ASAN each one copies and rewrites a ~1GB binary, so the file took 29s on debian 13 aarch64 (build 88024) and ~15s locally. This collapses the six compiles into two: one CLI binary that exercises the file-loader asset path, an `--asset` directory tree, an `--asset` single file, and the ENOENT/ENOTDIR/EISDIR/EACCES error codes; and one `Bun.build({compile: {assets}})` binary that covers the directory + single-file JS-API path including the index.js-does-not-collide-with-entry case. The seven error-path tests (collisions, bad flags, missing paths) are unchanged. ## Why this is correct Each of the four collapsed CLI tests probed an independent slice of the same `/\$bunfs/` virtual filesystem (parent-dir stat, recursive readdir, missing-path ENOENT, readdir-on-file ENOTDIR). None of them depend on the others being absent from the embedded file list, so running them against a single binary that contains all the assets checks exactly the same code paths. Same argument for the two JS-API tests: adding a `public/` directory alongside `cfg/index.js` does not change whether `index.js` collides with the entry, and the directory walk is unaffected by the extra single-file asset. Every original assertion is preserved. ## Assertion changes - Field-by-field `.toBe()` chains replaced with a single `.toEqual()` over the whole parsed result, so extra/missing fields now fail the test. - `client.recursive` was previously seven `toContain` checks; now an exact `toEqual` on the sorted array (so unexpected extra entries fail). - Added a `subCss` read in the JS-API test (previously only `index.html` was read back). - `embeddedFileCount` bound raised from `>= 4` to `>= 6` to match the merged asset set. No assertions removed, no tests skipped. ## Timing `time bun bd test test/bundler/compile-asset-bunfs.test.ts`, linux-x64, three runs each: | | before | after | | --- | --- | --- | | wall | 14.8s | 6.7s | | tests | 13 | 9 | | expect() | 70 | 26 | (fewer expect() calls because `.toEqual({...})` replaces many `.toBe()`; the assertions are strictly tighter) --- **no test proof** · iteration 0 · Platform-specific test-only change; deferring to CI. --- test/bundler/compile-asset-bunfs.test.ts | 290 +++++++++-------------- 1 file changed, 112 insertions(+), 178 deletions(-) diff --git a/test/bundler/compile-asset-bunfs.test.ts b/test/bundler/compile-asset-bunfs.test.ts index 40296f258d91..c7f66e69906f 100644 --- a/test/bundler/compile-asset-bunfs.test.ts +++ b/test/bundler/compile-asset-bunfs.test.ts @@ -17,7 +17,7 @@ async function compile(dir: string, extraArgs: string[] = []) { stderr: "pipe", });

Cliff is exactly at a 32 KiB backing file; slice size is irrelevant. ### Cause `src/runtime/webcore/fetch.rs`'s sendfile setup computed `content_size` as the whole file's `stat.st_size` for regular files, discarding the slice's own size: ```rust let blob_size = if bun_sys::S::ISREG(stat.st_mode as u32) { stat_size // <- ignores the slice window } else { original_size.min(stat_size) }; ``` `remain` was then separately clamped to the slice window, so `sendfile(2)` wrote the right bytes while `HTTPRequestBody::Sendfile(sf).len()` (= `sf.content_size`) produced the wrong `Content-Length`. ### Fix After the existing `remain` clamp for regular files, set `content_size = remain`; that is exactly the byte count `sendfile` will write. The now-redundant `blob_size` branch is dropped. ### Verification `test/js/bun/http/fetch-file-upload.test.ts` gains a `describe` covering slice uploads across the 32 KiB boundary (32767 / 32768 / 64 KiB / 1 MiB files) plus an open-ended `slice(10)`. All four boundary cases and the open-ended slice time out on `main` and pass with this change. The existing whole-file sendfile roundtrip test in the same file continues to pass. Related: #32794 fixes the same bug class on the `Bun.serve` response side; this is the `fetch()` client upload side. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Async content handlers no longer nest the event loop. ``` input body ──► SinkHandle::HTMLRewriter ──► lol_html::HtmlRewriter ──► output ByteStream ▲ │ └─────────── SourceHandle::HTMLRewriter (producer) ◄────────────────────┘ ``` ### Why `BufferOutputSink` fully buffered the source body via `ValueBufferer` before a single `rewriter.write()` + `end()`, and `handler_callback` spun `vm.wait_for_promise()` six native frames deep inside lol-html for any handler that returned a Promise. That meant handlers fired only at source-end (TTFB = full download), `.body` / `Bun.serve` saw an empty stream (#6068, #19305), JS-backed `ReadableStream` inputs were rejected outright (#11758, #14216), and the nested loop was a known hazard class (deadlocks, ready-poll clobbering, pending-exception leaks). lol-html could not be suspended before because its tokens are stack locals borrowing a stack-local lexeme; returning from `write()` destroys them, and an async handler must be able to mutate the element after its `await`. ### lol-html fork (`oven-sh/lol-html`, branch `bun`) A handler returns `Err(SuspensionRequest)` to suspend. The in-flight unit is deep-copied onto the heap, `write()`/`end()` return the non-poisoning `RewritingError::Suspended`, and `HtmlRewriter::resume()` continues from a `StateMachineBookmark`. The pending captured-text flush is hoisted from `Dispatcher::handle_tag` into the lexer actions so every suspension point has a uniform shape. `Arena::shift` advances a start offset instead of memmoving the tail (a suspended rewrite re-feeds its unconsumed tail on every resume). 23 in-crate tests added; the new `.github/workflows/lolhtml.yml` runs the fork's own `cargo test` at the pinned commit, gated on `scripts/build/deps/lolhtml.ts`. The fork is a `github-archive` source (no patch file), so rebasing onto a new upstream tag is a `git rebase --onto` in the fork plus a commit bump here. ### Bun side (`RewriterPipe` replaces `BufferOutputSink`) - **Ownership**: a generated `HTMLRewriterTransform` JS cell (not user-visible) owns the pipe; its GC finalizer frees it, and nothing pins anything. Liveness is plain GC edges: the output Response's `transform` WriteBarrier slot and the `.then()` context of a suspended handler's (or the JS pump's) promise reach the cell, the cell's five slots root the Response, the input/output streams, the pending flush promise, and a captured handler error, and a wired native source's `owner` WriteBarrier slot (new on the generated NewSource cells) points back at the cell, so I/O that roots the source (a FetchTasklet, a FileReader's read refs, a reader on the output stream) roots the rewrite for exactly the window the raw `SinkHandle`/producer backrefs are wired. A handler promise collected without settling lets `finalize` defer to an event-loop task (`abandon_suspension`) that rejects the body before freeing; the pipe holds one native `+1` on the Response (released in `Drop`) so that task can still reach the body. No intrusive refcount, no `Strong` fields on the pipe; `finish()` frees the boxed lol-html state machine eagerly, and `fail()`/output-cancel close the upstream producer instead of draining it to EOF. - **Output**: the returned `Response`'s body is `Locked(PendingValue { task: pipe, on_start_streaming, on_readable_stream_available, producer: SourceHandle::HTMLRewriter })`, the `FetchTasklet::to_body_value` shape. The `ByteStream` is created lazily when a consumer reads `.body` or a body-mixin method; until then, rewriter output buffers in a `Vec` handed over as `DrainResult::Owned`. - **Input**: mirrors `FetchTasklet::start_request_stream`. Native `ByteStream`/`FileReader` sources wire `byte_stream.sink = SinkHandle::HTMLRewriter` + `lock_native` + `drain()`; other stream kinds go through `JSSink::::assign_to_stream` (new `HTMLRewriterSink` codegen entry). Materialized bodies (`InternalBlob`/bytes `Blob`/`WTFStringImpl`) feed synchronously. - **Backpressure**: `RewriterPipe::write` feeds one chunk through `rewriter.write()` (output chunks push via `ByteStream::on_data`). If the output is paused or a handler suspended, `write` returns `Writable::Backpressure`; `ByteStream::resume` → `SourceHandle::HTMLRewriter::on_ready` → `pipe.resume()` drains `pending_input` then `input_source.ready()`. - **Async handlers**: `handler_callback` returns `HandlerOutcome::{Continue, Stop, Suspend}`. On a pending Promise it runs one microtask checkpoint (`process.nextTick` then promise jobs, never the loop); a genuinely pending Promise suspends. The JS wrapper is retargeted at the heap-parked token so post-`await` mutations land where they should. The `.then()` context is the Transform cell itself (the reactions recover the pipe via `from_js`), so a handler promise collected without settling abandons the parked rewrite instead of leaking it. - **Error handling**: `handler_error` on the pipe replaces the stack `Cell` + `unhandled_pending_rejection_to_capture` override. A handler error on a streaming input now rejects the body with the real error instead of `The rewriter has been stopped.`. - `AttributeIterator` holds a backref to the `Element` plus an index instead of a boxed `slice::Iter`, so `for (const [k, v] of el.attributes) { await ... }` keeps working across a suspension. ### Deletions `ValueBufferer` (~430 lines of `Body.rs`) and its host-fn exports; `SinkHandle::ValueBufferer` + `SinkWriteFn`; `JSSink::detach_self`; `crate::Error::{StreamAlreadyUsed, InvalidStream, UnsupportedStreamType}`; `NativePromiseContext::Tag::BodyValueBufferer` (ordinal 4 reused for `HTMLRewriterSuspension`); the two `Bun__BodyValueBufferer__*` `PromiseFunctions` (slots reused for `Bun__HTMLRewriter__onHandler{Resolve,Reject}`). ### Behavior changes 1. **Error channel is decided by the overload, not by timing.** `transform(string)` / `transform(ArrayBuffer)` throw from `transform()`. Every `Response` input rejects its output body instead. Five existing tests that pinned the old timing-dependent split are updated. Input-body errors (already-failed or aborted body) still throw synchronously from `transform()`. 2. A handler whose Promise needs the event loop to turn makes `transform(string)` / `transform(ArrayBuffer)` throw a `TypeError` (`pass a Response and await its body`) instead of spinning. A Promise that settles within a microtask checkpoint still works. 3. A rejection a handler neither awaits nor returns reaches `unhandledRejection` instead of being captured and thrown from `transform()`. 4. `transform()` types corrected: `Bun.BufferSource` returns `ArrayBuffer` (it always has at runtime); `Blob` removed from the overload (it threw at runtime). 5. `Bun.serve` with an HTMLRewriter-produced response body defers status/headers until the first body byte or clean end, so a handler that fails before emitting any bytes is routed to the server'''s `error()` hook instead of committing `200 OK` then force-closing the connection. Headers never preceded the first byte on this path before either (the old implementation buffered the whole rewrite). All other native-ByteStream bodies (proxied `fetch()`, S3, spawn stdout) keep sending status/headers immediately, and JS `ReadableStream` bodies (`do_render_stream`) are unchanged. `docs/runtime/html-rewriter.mdx` and `packages/bun-types/html-rewriter.d.ts` cover 1-4. ### Verification - `test/js/workerd/html-rewriter.test.js`: 107 pass, 0 fail under ASAN debug and under `BUN_JSC_validateExceptionChecks=1`. New coverage: async element/text/comment/doctype/onEndTag/document-end handlers, `Bun.gc(true)` while an element is heap-parked across an `await`, re-suspension by a second handler on the same element, nested `transform()` inside a suspended handler, strict document-order across 8 awaiting handlers, `Bun.serve` with a live client, client abort mid-suspension, the consumer matrix for a pending output body, JS-backed and `type:'direct'` `ReadableStream` inputs. - `test/js/workerd/html-rewriter-leak.test.ts`: protected-object + `Response` count regression over 120 suspending rewrites; a never-settling handler rejects the body instead of leaking. - Fail-before: `works with payload of type direct` → `ERR_STREAM_CANNOT_PIPE` on the released bun. - `bun-types` green, `cargo clippy -p bun_runtime` clean. - `vendor/lolhtml/.ref` re-fetch of the fork verified through the real ninja edge. Fixes #11758 Fixes #14216 Fixes #6068 Fixes #19305 Closes #33243 (same lol-html fork, different input layer), Closes #35324 (ResumableSink, deleted in #36087), Closes #32988 (per-chunk ValueBufferer callback). --- **no test proof** · iteration 20 · Platform-specific test(s) that do not run on this machine.

The crash is not catchable from JS and the report reads like a Bun bug. ## Fix Before calling `dlopen` on Linux, walk the addon's `PT_DYNAMIC` segment and inspect its `DT_NEEDED` list. On musl builds, if any entry is a glibc soname (`libc.so.6` / `libpthread.so.0` / `libm.so.6` / `libdl.so.2` / `librt.so.1` / `libresolv.so.2` / `libutil.so.1` / `ld-linux-*`), throw `ERR_DLOPEN_FAILED` with a message that names the mismatch and points at the fix: ``` ERR_DLOPEN_FAILED: .../onnxruntime_binding.node is linked against glibc (DT_NEEDED libc.so.6), but this Bun build uses musl. glibc-targeted native addons cannot be loaded on Alpine/musl even with gcompat. Use a glibc-based image (e.g. oven/bun:debian) or install a musl build of this addon. ``` The parser (`src/runtime/napi/libc_check.rs`) reads only the ELF header, program-header table, dynamic section, and the front of `.dynstr` via `pread`, so the cost is a handful of small reads per addon load. Any I/O or parse failure returns "no mismatch" so a working addon is never refused; `libstdc++.so.6` and `libgcc_s.so.1` are deliberately not treated as glibc markers since Alpine packages real copies. On glibc builds the function short-circuits to a no-op. ## Verification `test/regression/issue/15753.test.ts` synthesises a minimal ELF64 shared object with a configurable `DT_NEEDED` and `e_machine = EM_NONE` (so the real loader rejects it cleanly when the pre-check passes it through). It asserts that a `libc.so.6` addon is rejected with the glibc/musl message, a `libc.musl-*` addon is passed to `dlopen`, a non-ELF file falls through, and the check is inert on glibc hosts without `BUN_INTERNAL_NAPI_FORCE_MUSL_CHECK`. Also exercised manually against the real `onnxruntime_binding.node` from `onnxruntime-node@1.14.0`. --- **no test proof** · iteration 9 · Platform-specific test(s) that do not run on this machine.

Each symbol was verified to have zero callers across `src/`, `build/debug/codegen/`, and `src/codegen/`; `bun bd` and `bun run rust:check-all` (10/10 targets) pass with them removed. ### Removed - **`src/resolver/fs.rs`**: `impl Clone for Entry` + `impl Default for Entry` (32 lines). The `Clone` comment claimed `BSSList::append` requires `ValueType: Clone`, but `OverflowList::append` at `src/bun_alloc/lib.rs:1887` has no such bound and all `Entry` construction goes through `append_uninit` + field-wise raw writes. No `.clone()` / `Entry::default()` anywhere. - **`src/resolver/result.rs`**: `impl Default for DirEntryResolveQueueItem` (15 lines). The queue is `[MaybeUninit<_>; 256]` populated only via `.write(DirEntryResolveQueueItem { })` at resolver.rs:4140/4195/4233. - **`src/resolver/lib.rs`**: `impl Default for cache::Fs` (11 lines). `Set::init()` builds `Fs` with all four fields explicit; the two `..Default::default()` in this file are for `bun_sys::WindowsOpenDirOptions`. - **`src/install/lockfile/Package/Scripts.rs`**: `PrintFormat::Info` variant + its match arm (6 lines). `pm_trusted_command.rs` only ever passes `Untrusted`/`Completed`; `Info` is never constructed. - **`src/install_types/resolver_hooks.rs`** + re-exports in `install_types/lib.rs` and `install/lib.rs`: `OldV2VersionedURL` type alias (4 lines). Zero references to the alias name anywhere. - **`src/event_loop/ManagedTask.rs`**: `ManagedTask::cancel` (7 lines). No caller invokes `.cancel()` on a `ManagedTask`; the `.cancel()` calls in napi/s3/h3/ReadableStream are on unrelated types. - **`src/runtime/node/node_fs.rs`**: `StatOrNotFound::to_js` (6 lines). Exact duplicate of `to_js_newly_created`; the `FsReturn` impl for `StatOrNotFound` calls `to_js_newly_created` directly. - **`src/runtime/webcore/fetch/FetchRequestBodySink.rs`** + `fetch.rs`: `FetchRequestBodySinkJSSink` type alias + re-export + now-unused `JSSink` import (3 lines). Both callers (`FetchTasklet.rs:439,683`) spell out `JSSink`; not referenced by `generate-jssink.ts`. ### Verification ``` rg -w src/ build/debug/codegen/ src/codegen/ # zero hits outside own definition for every item above bun bd # builds bun run rust:check-all # 10/10 targets ok (linux/macos/windows x x64/aarch64) bun bd test test/js/node/fs/fs.test.ts -t stat # 18 pass bun bd test test/js/bun/resolve/resolve.test.ts # 48 pass bun bd test test/cli/install/bun-pm.test.ts -t trust # 4 pass ``` ### Followups (not removed; listed for reference) Candidates that looked dead to `rg` but have cross-crate callers discovered at build time (kept): `AutoBitSet::{bytes,for_each}` (bundler computeChunks), `impl Default for cache::Entry` (bundler ParseTask), `NullDelimitedEnvMap::as_slice` (js_bun_spawn_bindings, shell subproc), `BlobOrStringOrBuffer::byte_length` (ValkeyCommand). Unremoved because reachable via `strum::EnumString` string parse: `RedisError::{InvalidArgument,InvalidArray,InvalidBigNumber,InvalidErrorString,InvalidNull,InvalidSimpleString}`, `AnyPostgresError::{InvalidByteSequenceForEncoding,InvalidTimeFormat}`. These are never directly constructed but are parse targets of `.name().parse()` and removing them would silently change error-code mapping if a source enum gains a matching variant name. ### Note on LOC This run's yield is well below the 1000 LOC target. The tree has been aggressively swept over the last three weeks: 10 merged + 5 open dead-code PRs, including commit 85ddc95b21 which removed ~39k lines in one pass. A full fan-out across `src/http`, `src/install`, `src/runtime/webcore`, `src/runtime/node`, `src/runtime/api`, `src/bun_core`, `src/jsc`, `src/collections`, `src/resolver`, `src/ast`, `src/semver`, `src/dotenv`, `src/patch`, `src/glob`, `src/watcher`, `src/event_loop`, `src/sql/postgres`, `src/valkey`, and the C++ bindings found ~40 candidates, of which ~15 proved genuinely unreferenced after build-time verification. --- **[review]** gate passed · iteration 0 · 12 files touched

The `?sslmode=` URL query was already enforced; only the env plumbing was missing. ## Repro Against a plaintext-only postgres (or any server with `ssl=on` and `pg_stat_ssl` to inspect): ```sh PGSSLMODE=require PGHOST=127.0.0.1 PGPORT=5432 PGUSER=postgres PGPASSWORD=pw PGDATABASE=postgres \ bun -e 'await new Bun.SQL({max:1}).connect(); console.log("connected")' ``` Before: connects and authenticates over plaintext. After: `PostgresError: The server does not support SSL connections [ERR_POSTGRES_TLS_NOT_AVAILABLE]` (same as `?sslmode=require` on a URL already produced). ## Cause `parseOptions` in `src/js/internal/sql/shared.ts` initialises `sslMode` from the `TLS_*` URL env vars and the URL `?sslmode=` query, then falls through to per-adapter env defaults for host/port/user/password/database, but there was no corresponding read of `PGSSLMODE`. ## Fix Read `PGSSLMODE` (and `PG_SSLMODE`, matching the existing `PG_HOST`/`PG_PORT`/... spellings) through the existing `normalizeSSLMode` validator as the default when the adapter is postgres. A URL `?sslmode=` still overrides it (libpq precedence). ## Verification - `test/js/sql/adapter-env-var-precedence.test.ts`: new `PGSSLMODE` describe block covering each mode value, the defaulted-adapter path, the `PG_SSLMODE` spelling, URL-overrides-env precedence, no leak into the MySQL adapter, and invalid-value rejection. - `test/js/sql/postgres-pgsslmode-env.test.ts`: wire-level check against a mock plaintext-only server.

That helper intentionally maps both `undefined` and `NaN` to the default (it is used elsewhere for optional integer properties), so both values came out as `0` and were serialized onto the wire. Every other bad value is already rejected loudly: `-5`/`2**62`/`Infinity` throw `ERR_OUT_OF_RANGE`, `1.9`/`"10"`/`null` throw `ERR_INVALID_ARG_TYPE`. Only `NaN` and `undefined` fell through silently. `expire` is the only typed helper that does this client-side coercion; `pexpire`/`expireat`/`setex`/`getex`/`incrby`/... stringify their argument and pass the literal `"NaN"`/`"undefined"` to the server, which rejects it. ## Fix Reject `undefined` and `NaN` in `expire()` before the range check, using the same `ERR_INVALID_ARG_TYPE` the validator already uses for non-integer and non-number inputs. After: ``` expire(k,NaN): ERR_INVALID_ARG_TYPE expire(k): ERR_INVALID_ARG_TYPE wire: [] ``` ## Verification ``` bun bd test test/js/valkey/valkey.test.ts -t "RedisClient argument validation" ``` The new test is client-side only (validation happens before any network I/O), so it runs without a docker redis. It fails on `main` (`toMatchObject` receives `undefined` because `expire('k', NaN)` did not throw) and passes with this change. --- **[review]** gate passed · iteration 0 · 2 files touched

Its ABI-147 prebuild referenced 89 V8/node symbols Bun did not export, so loading it aborted the process at the dynamic linker: ``` bun: symbol lookup error: .../dd_pprof.node.abi147.node: undefined symbol: _ZN2v816FunctionTemplate12SetClassNameENS_5LocalINS_6StringEEE ``` Fixes #11968. ## How ### CpuProfiler (the core) `v8::CpuProfiler` / `CpuProfile` / `CpuProfileNode` are declared opaque in `v8-profiler.h` (no inline methods, no visible fields), so the shim uses plain heap structs reinterpret_cast'd to the public pointer types. `CpuProfiler::Start` drives `JSC::SamplingProfiler` (`vm.ensureSamplingProfiler()`, `setTimingInterval`, `start()`); `Stop()` releases the stack traces and aggregates them into a top-down call tree using the same algorithm `BunCPUProfiler.cpp` uses for `--cpu-prof`, then exposes it through the `CpuProfileNode` getters. ### Template system (the nan ObjectWrap class pattern) `FunctionTemplate::{SetClassName, InstanceTemplate, PrototypeTemplate}`, `Template::{Set, SetNativeDataProperty}`, `Signature::New`, and `PropertyCallbackInfo`. `shim::FunctionTemplate` now stores per-template property/accessor records and lazily-created instance/prototype `ObjectTemplate`s. `GetFunction()` materializes a prototype object from the PrototypeTemplate's records; `Function::NewInstance()` allocates an `InternalFieldObject` from the InstanceTemplate and invokes the callback as a construct call. ### Everything else `Function::Call`, `ArrayBuffer`/`BackingStore`/`ArrayBufferView`/`Uint8Array`/`Uint32Array`, `Integer`, `BigInt`, `Map::{Set,Delete}`, `Exception::{Error,TypeError}`, `Isolate::{ThrowException, ThrowError, RequestInterrupt, Add/RemoveGCPrologue/Epilogue/NearHeapLimitCallback, GetEnteredOrMicrotaskContext, LowMemoryNotification, IsInUse, GetContinuationPreservedEmbedderData, GetHeapProfiler}`, `Object::{DefineOwnProperty, GetIdentityHash, InternalFieldCount, Set/GetAlignedPointerInInternalField}`, `String::NewFromUtf8Literal`, `Value::{IsUint8Array, ToString, ToInteger}`, `Context::Global`, `api_internal::{MakeWeak, ClearWeak, MoveGlobalReference}`, `base::TimeTicks::Now`, `HeapObjectStatistics`, `internal::Internals::GetCurrentIsolate`, `ToExternalPointerTag`, and `node::{MakeCallback, GetCurrentEventLoop, EmitAsyncInit, EmitAsyncDestroy, AsyncHooksGetExecutionAsyncId}`. `HeapProfiler::StartSamplingHeapProfiler`/`Stop` are no-ops and `GetAllocationProfile()` returns `nullptr` (JSC has no sampling heap profiler; pprof's heap path checks for null). Each exported symbol is registered in `napi_body.rs` (Itanium + MSVC, extern block + DCE keep-list), `symbols.txt`, and `symbols.dyn`. ## Verification **Original repro** (`dd-trace` with `profiling: true`): ``` DATADOG TRACER CONFIGURATION - {...,"profiling_enabled":true,...} dd-trace initialized without crashing still alive after 1s ``` **Profiling actually works** (`@datadog/pprof` `time.start()`/`stop()` on a 1s hot loop at 1ms interval): ``` unique samples: 3 stack: spin count: 901 wall_ns: 1000110000 total sample count: 905 total wall ms: 1004.5 ``` **Stack depth** (recursion at depth 5): ``` max stack depth: 6 stack: recurse <- recurse <- recurse <- recurse <- recurse <- recurse ``` **Tests:** - `test/v8/v8.test.ts`: 72 pass, 1 skip, 0 fail (adds Integer, BigInt, DefineOwnProperty, ArrayBuffer/TypedArray, Function::Call/NewInstance, Map, Exception, aligned internal fields, PrototypeTemplate/Template::Set/SetNativeDataProperty, NewFromUtf8Literal, CpuProfiler cases; all compared against Node via `checkSameOutput`) - `test/v8/datadog-pprof.test.ts`: installs `@datadog/pprof@5.17.0`, runs `time.start()/stop()`, asserts the returned pprof profile names the hot function Fail-before: both tests crash on system bun with the issue's `undefined symbol: _ZN2v816FunctionTemplate12SetClassName...` linker error. --- **no test proof** · iteration 13 · Platform-specific test(s) that do not run on this machine.

From d76edcf7e6986dadd46fc92599a8926f17298d31 Mon Sep 17 00:00:00 2001 From: robobun Date: Mon, 3 Aug 2026 22:14:42 -0700 Subject: [PATCH 091/304] js_parser: stop the [x][0] / {f:x}.f folds from changing optional-chain / this / assignment semantics (#36730) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem With `minify_syntax` on (the default for `bun run`), the `[x][0] -> x` and `{f: x}.f -> x` folds were replacing an index/property Reference with a bare value without fully checking the parent context. All of these reproduce against Node on current main: ```js var a = null; [[a?.b]][0]?.[0].c; // Node: TypeError Bun: undefined (output: a?.b.c) new ({f: a?.b}).f(); // Node: runs Bun: SyntaxError (output: new a?.b) var obj = { m() { return this === obj } }; [obj.m][0](); // Node: false Bun: true (output: obj.m()) var o = { p: 1 }; [o.p][0] = 5; o.p; // Node: 1 Bun: 5 (output: o.p = 5) "foo"[2] = 1; // Node: no-op Bun: SyntaxError (output: "o" = 1) ``` The direct form `[a?.b]?.[0].c` is hidden on main because the parse-time "drop `?.` on a non-nullable literal" simplification clears the outer chain first and the printer inserts `(a?.b)`; one level of indirection (`[[a?.b]][0]?.[0].c`, `({f:[a?.b]}).f?.[0].c`) bypasses that. ## Fix - `can_be_inlined_from_property_access` now rejects `EDot`/`EIndex`/`ECall` whose `optional_chain` is set, so an optional chain is never spliced onto a surrounding `?.` continuation and never lands as a bare `new` / template-tag target. - Both folds now route through that predicate (the `{f: x}.f` fold previously did not). - The `e_index` fold bails when `in_.assign_target != None`, so `[x][0] = v`, `"s"[n] = v` and `[,][0] = v` are left as written instead of producing `x = v` / `"s" = v` / `void 0 = v`. - When the `e_index` fold is a call target and the inlined item is an `EDot`/`EIndex`, it emits `(0, x)()` instead of `x()`, matching the sibling comma/`??`/`||`/`&&`/ternary folds so `this` is not rebound. - The multi-item path's `debug_assert!` on the predicate becomes a real guard (reachable via a `/* @__PURE__ */ a?.()` array item). The folds still fire for plain targets: `[a.b][0].c -> a.b.c`, `[[y]][0]?.[0].c -> y.c`, `[y][0]() -> y()`, `({f: y}).f -> y`, `new ({f: C}).f() -> new C`. esbuild does not perform these folds at all, so the remaining bailouts bring Bun in line with its output. ## Out of scope (tracked separately) Two pieces of parser-context tracking were never wired up in the Rust port, so the corresponding parent positions are not yet covered here for plain (non-chain) items: - `p.delete_target` is never set by the `UnDelete` arm, so `delete [obj.p][0]` still folds to `delete obj.p`. Wiring it up turns on every dormant `is_delete_target` guard in the visitor (bundler "cannot assign to import", CJS-named-export deopt, enum/namespace inlining under `delete`). - `is_template_tag` is commented out, so `[obj.m][0]`x`` still rebinds `this`. Wiring it up touches every sibling fold (comma/`??`/`||`/`&&`/ternary). Both are pre-existing and have a blast radius beyond this fold; the optional-chain bailout already keeps `delete [a?.b][0]` and `[a?.b][0]`x`` unfolded in the meantime. ## Verification - `bun bd test test/bundler/transpiler/transpiler.test.js -t "property access inlining"` passes (8 tests); the three new tests fail with `src/` reverted to main. - Full `transpiler.test.js` (186 pass / 0 fail) and `bundler_minify.test.ts` (42 pass / 0 fail) are green. --- **[review]** gate passed · iteration 1 · 4 files touched

The bundler correctly emits `delete (0, ns.x)` under `--no-bundle`, but when bundling the `??` folds away and `ns.x` is rewritten to an `EImportIdentifier` pointing at the hoisted binding. The printer's `(0, ...)` re-wrap at `src/js_printer/lib.rs:4004` is driven by `is_identifier_or_numeric_constant_or_property_access`, which only recognised `EIdentifier | EDot | EIndex` and so let the `EImportIdentifier` through as a bare `delete x`. The same gap applies to every visit-pass rewrite that can land as a `delete` operand after a fold and prints as an identifier or property access: | node | example | previously printed | |---|---|---| | `EImportIdentifier` | `delete (null ?? ns.x)` (namespace import) | `delete x` | | `ECommonjsExportIdentifier` | `delete (null ?? exports.a)` under cjs2esm | `delete $a` | | `ESpecial::ModuleExports` | `delete (null ?? module.exports)` under cjs2esm | `delete exports_entry` | | `ERequireCallTarget` | `delete (null ?? require)` | `delete __require` | | `ERequireMain` / `ERequireResolveCallTarget` | `delete (null ?? require.main)` | `delete __require.main` | | `EInlinedEnum` wrapping `NaN`/`Infinity` | `const enum E { N = 0/0 }; delete (null ?? E.N)` | `delete NaN` | | `EUndefined` | `delete (null ?? undefined)` (define substitution) | `delete undefined` | | `EImportMetaMain` | `delete (null ?? import.meta.main)` | `delete import.meta.main` / `delete __require.main == __require.module` | | `EImportMeta` (bake dev / CJS ref) | `delete (null ?? import.meta)` | `delete hmr.importMeta` | Each bare-identifier form is a strict-mode SyntaxError in the emitted ESM bundle; the property-access forms delete a property the source never touched. `WAS_ORIGINALLY_DELETE_OF_IDENTIFIER_OR_PROPERTY_ACCESS` is set at parse time from the syntactic operand, so it is correctly unset for `delete (null ?? ns.x)`; the wrap just needs to recognise the post-visit node kinds. ## Fix Extend `is_identifier_or_numeric_constant_or_property_access` to match `EImportIdentifier | ECommonjsExportIdentifier | ESpecial | ERequireCallTarget | ERequireResolveCallTarget | ERequireMain | EImportMeta | EImportMetaMain | EUndefined`, and recurse through `EInlinedEnum` so the existing `NaN`/`Infinity` check reaches the wrapped value. The helper is only consulted when the parse-time flag is not set, so `delete ns.x` / `delete require` (flag set) continue to print without the wrap and this can only add wraps where the source never had Reference semantics. esbuild's `isIdentifierOrNumericConstantOrPropertyAccess` has the same `EImportIdentifier` gap and `esbuild --bundle` miscompiles the first repro the same way; the other node kinds are either Bun-specific or print differently in esbuild. This is orthogonal to #36734 (which makes `p.delete_target` live in the visitor): `ns.x` inside `(null ?? ns.x)` is not the delete target there either, so that PR does not cover this path. ## Verification ```console $ bun bd test test/bundler/bundler_edgecase.test.ts -t DeleteFolded # 8 new tests; fail on main $ bun bd test test/bundler/bundler_cjs2esm.test.ts -t DeleteFolded # 3 new tests; fail on main ``` Full `bundler_edgecase.test.ts`, `bundler_cjs2esm.test.ts`, `bundler_minify.test.ts`, `transpiler.test.js`, `esbuild/default.test.ts`, `esbuild/ts.test.ts`, `esbuild/dce.test.ts` unchanged. --- **no test proof** · iteration 8 · Platform-specific test(s) that do not run on this machine.

From 59cab0e977391a0fe834b6ca9db92108fcd7dd1a Mon Sep 17 00:00:00 2001 From: robobun Date: Mon, 3 Aug 2026 22:28:24 -0700 Subject: [PATCH 093/304] webstreams: native CompressionStream/DecompressionStream/TextEncoderStream/TextDecoderStream (#36695) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## What Rewrites `CompressionStream`, `DecompressionStream`, `TextEncoderStream`, and `TextDecoderStream` as native C++ `JSTransformStream` subclasses that drive Rust state directly, and adds a native-sink output path so coder output goes straight to a native JSSink (HTTPResponseSink, FileSink, etc.) without a `JSUint8Array` per chunk. ## Before - `CompressionStream` / `DecompressionStream`: JS builtins that `require("node:zlib")`, wrap a Node duplex in `newBufferSourceTransformPairFromDuplex`, and round-trip every chunk through the threadpool. - `TextEncoderStream` / `TextDecoderStream`: C++ cells with `TransformerKind` arms, but each chunk did `encoder->get(global, "encode")` + `JSC::call(...)` on a held JS wrapper cell; `TextDecoderStream` also allocated a `{stream: true}` options object per chunk. - `readStreamIntoSink` (every `Response(stream)` → native sink pump) did a prototype `.write()` lookup + `JSC::call` per chunk. ## After **Native cells**: each instance cell IS a `JSTransformStream` (C++ subclass), so `m_readable`/`m_writable`/`m_controller`/`m_backpressure` live on the instance and there is no second cell. `JSTransformStream` stays `JSNonFinalObject`; each subclass registers a per-instance `vm.heap.addFinalizer` only when it actually allocated native state (a utf-8 non-fatal `TextDecoderStream` registers nothing). The coder/decoder is freed eagerly at `ClearAlgorithms` (post-flush / error / cancel) so zlib/brotli/zstd window buffers don't wait for a full GC; an in-use guard (`runNativeArm`) defers that free when `ClearAlgorithms` is reached re-entrantly from user JS inside a transform arm's chunk coercion. `setUpNativeTransformStream()` initializes the subclass in place; the JS-visible prototype chain is unchanged (`instanceof TransformStream` stays false). **Rust coder**: `src/runtime/webcore/CompressionStreamCoder.rs` holds one zlib/brotli/zstd context per stream and implements gzip concatenated members (RFC 1952 2.2), zstd concatenated + skippable frames (RFC 8878 3.1) with cross-chunk magic buffering, truncated-input detection on flush, and trailing-junk rejection (`ERR_TRAILING_JUNK_AFTER_STREAM_END`). zlib `avail_in` is clamped to `u32::MAX` and refilled per loop so a ≥4 GiB chunk is not truncated. **TextDecoderStream utf-8 fast path**: `new TextDecoderStream()` with utf-8 and `fatal:false` (the default) shares `Body.textStream()`'s `streamingUTF8Decode` (simdutf, 4-byte inline state); no Rust `TextDecoder` is allocated. `ignoreBOM` maps to the initial `bomSeen` flag. Other encodings and `fatal:true` use the Rust `TextDecoder`. **TextEncoderStream native-sink path**: when a native sink is attached, the encoder writes into a per-encoder reusable `Vec` and hands it to `Bun__JSSink__writeBytesById` directly; no `JSUint8Array` per chunk. **Native-sink output path**: `readStreamIntoSink` detects when the readable is a byte-producing `TransformerKind` (Compression/Decompression/TextEncoder) and attaches the native sink (`m_nativeSinkPtr`/`m_nativeSinkId`/`m_nativeSinkCell`) to the transform. The transform arms then run the coder into a `Vec` and hand those bytes to `Bun__JSSink__writeBytesById` (dispatched by the controller's `SinkID`) before dropping the Vec. Sink backpressure holds the in-flight write via `m_nativeSinkReadyPromise`, resolved by the sink's `onReady`. `rsisDetachNativeTransform` clears the attachment before every sink `end()`/`close()` (including the sink-initiated `onClose` callback). **JSSink `writeBytes`**: each generated sink type gains `${name}__writeBytes(void* sinkPtr, JSGlobalObject*, const uint8_t*, size_t)` (forwards to Rust `JsSinkType::write_bytes`), plus `JSSink__writeBytes(SinkID, ...)` / `Bun__JSSink__writeBytesById` dispatchers. `rsisSinkWrite` uses it directly for `JSArrayBufferView` chunks instead of the prototype `.write()` lookup (benefits every byte stream, not only these four). **readableHighWaterMark = 1** for the native subclasses (not the spec's 0) so a single `await writer.write(x)` completes before any reader is attached, matching Node.js and Chromium. ## Benchmark Release build `bb790d282` vs canary main `87e168fb0` (post-SinkHandle), 3-run median, 200 × 64 KB per iteration: | case | main | this PR | Δ | |---|---|---|---| | CompressionStream(gzip) collect | 23.1 MB/s, 1881 ms cpu | 46.3 MB/s, 1359 ms cpu | **2.0x, -28% cpu** | | CompressionStream(gzip) Bun.serve | 23.8 MB/s, 2309 ms cpu | 45.9 MB/s, 1504 ms cpu | **1.9x, -35% cpu** | | DecompressionStream(gzip) collect | 920 MB/s, 99.6 ms cpu | 1046 MB/s, 60.2 ms cpu | **+14%, -40% cpu** | | TextEncoderStream collect | 3147 MB/s | 3214 MB/s | ~same | | TextEncoderStream Bun.serve | 510 MB/s | 503 MB/s | ~same | | TextDecoderStream collect | 1944 MB/s | 1782 MB/s | -8% (noise) | | RSS delta | 120 MB | 90 MB | **-25%** | The compression/decompression speedup is from dropping the `node:zlib` duplex adapter and its per-chunk threadpool round-trip.

Zlib/zstd decode errors become `TypeError("inflate failed" / "zstd decode failed")` without the previous library-specific `.code`; Node's own `test-webstreams-compression-bad-chunks.js` (which this PR passes) only asserts `name: 'TypeError'` for those. ## Not in this PR - TextEncoderStream pure-ASCII zero-copy path (`GCOwned` → `Temporary` straight to the sink) - `HTMLRewriter` native-sink path (same shape, follow-up) --- **no test proof** · iteration 16 · Platform-specific test(s) that do not run on this machine.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem `write_pre_quoted_string_inner` in `src/js_printer/lib.rs` (and its `bun_core::string::printer` mirror) emit `\x07` for U+0007 and `\v` for U+000B even when the `json` flag is set. Neither is a valid JSON escape: RFC 8259 only permits `\" \\ \/ \b \f \n \r \t \uXXXX`. Every caller of `write_json_string` / `quote_for_json` is affected. The most visible one is sourcemap generation: building a file that contains a vertical tab or bell character produces a `.map` that `JSON.parse` rejects. ``` $ printf '// [\x0b\x07]\nconsole.log(1);\n' > in.js $ bun build ./in.js --sourcemap=external --outdir=out $ bun -e 'JSON.parse(require("fs").readFileSync("out/in.js.map","utf8"))' SyntaxError: JSON Parse error: Invalid escape character v ``` The emitted `sourcesContent` contained `\v` and `\x07` literally. ## Fix When `json` is true, emit `\^G` / `\u000B` for these two code points; the JS-output path (`json == false`) is unchanged. All other C0 control characters were already routed to the `\uXXXX` fallthrough. This matches esbuild and `JSON.stringify`: ``` $ node -e 'console.log(JSON.stringify("\x0b\x07"))' "\u000b\^G" ``` ## Verification New test in `test/bundler/bun-build-api.test.ts` builds a source containing every C0 control character (0x00..0x1F), asserts the sourcemap text contains no `\v` / `\xNN`, and round-trips `sourcesContent[0]` through `JSON.parse` back to the original bytes. --- **no test proof** · iteration 3 · Platform-specific test(s) that do not run on this machine.

Both are safe when Bun opened the destination with `O_CREAT|O_TRUNC`, but for a caller-supplied fd they discard whatever the file already contained. - **FreeBSD** and the **Linux read/write fallback** (kernel < 4.5, `EXDEV`, `ENOTSUP`, `EINVAL`, or `BUN_CONFIG_DISABLE_COPY_FILE_RANGE`): `copy_file_using_read_write_loop` reads the source to EOF regardless of `max_length` and then `ftruncate(dest, total_written)` sets the file length, with the same effect. The Linux `copy_file_range`/`sendfile`/`splice` happy path already copies exactly `max_length` bytes and does not truncate, so this only shows up there when the kernel syscall is unavailable for the fd pair. ## Fix Add `read_write_loop_capped`, a bounded `read()`/`write()` loop that transfers exactly `cap` bytes (or to EOF) and never touches the destination's length. Route every fd-backed destination through it: - macOS/FreeBSD `run_async`: take the `fcopyfile`/`ftruncate` branch only when `destination_file_store.pathlike` is a path. - Linux `do_copy_file_range`: the three identical fallback sites are factored into `read_write_fallback`, which keeps the existing copy-to-EOF + `ftruncate` for path destinations and uses the bounded loop for fd destinations. ## Verification Two tests in `test/js/bun/io/bun-write.test.js` under `Bun.write(Bun.file(fd), Bun.file(path)) does not truncate the fd` spawn a child with `BUN_CONFIG_DISABLE_COPY_FILE_RANGE=1` so they fail-before on every POSIX lane: ``` === system bun === (fail) preserves bytes past the slice window in an r+ fd resolved: "200000", content: 200000 x "S" (expected "5", "SSSSS" + 25 x "D") (fail) preserves pre-existing bytes when stdout is redirected with >> resolved: "1000", content: 1000 bytes (expected "100", 110 bytes) === this branch === (pass) preserves bytes past the slice window in an r+ fd (pass) preserves pre-existing bytes when stdout is redirected with >> ``` The existing `Bun.write(Bun.stdout, Bun.stdin) copies the whole pipe` test is widened from Linux-only to every POSIX lane, covering the bounded loop's EOF-termination branch on macOS/FreeBSD. `cargo check -p bun_runtime --target {aarch64,x86_64}-apple-darwin` and `--target x86_64-unknown-freebsd` pass. ## Related Found during review of #36692 (which routes a FIFO source through `splice` on Linux; the `bun_opened_dest` guard it adds to the same three fallback sites is subsumed by `read_write_fallback` here). #32859 reworks the same block to honour source slices and #33715 sets `read_len` after `fcopyfile`; both are complementary and will need a small rebase against whichever lands first. --- **no test proof** · iteration 4 · Platform-specific test(s) that do not run on this machine.

Any peer that can open a TCP connection to an h2/h2c Bun server can trigger it. Node and Bun 1.4.0 both survive the same bytes; this is a regression on main from the http2 inbound rewrite (#31584). ```js // h2c server + raw prior-knowledge client in one file import http2 from "node:http2"; import net from "node:net"; const srv = http2.createServer((req, res) => res.end("ok")); srv.listen(0, () => { const s = net.connect(srv.address().port, () => { const pre = Buffer.from("PRI * HTTP/2.0\r\n\r\nSM\r\n\r\n"); const settings = Buffer.from([0, 0, 0, 4, 0, 0, 0, 0, 0]); // empty SETTINGS const bad = Buffer.from([0xff, 0xff, 0xff, 0xff, 0xff]); // invalid HPACK block const hdr = Buffer.alloc(9); hdr.writeUIntBE(bad.length, 0, 3); hdr[3] = 0x01; // HEADERS hdr[4] = 0x05; // END_HEADERS | END_STREAM hdr.writeUInt32BE(1, 5); s.write(Buffer.concat([pre, settings, hdr, bad])); }); setTimeout(() => { console.log("server survived"); process.exit(0); }, 1500); }); ``` ``` error: Stream closed with error code NGHTTP2_COMPRESSION_ERROR code: "ERR_HTTP2_STREAM_ERROR" at _destroy (node:http2:1690:31) ... at emitStreamErrorNT (node:http2:2202:21) ``` Node prints `server survived`. ### Why Bun creates the JS `ServerHttp2Stream` eagerly in the `streamStart` handler, before the header block is decoded. When the block fails to decode, the engine sends GOAWAY (COMPRESSION_ERROR) and the session is destroyed with that code, which tears down every open stream, including the one that was never announced: the `'stream'` event never fired, so no user code ever saw it and nothing can be listening for `'error'` on it. `emitStreamErrorNT` already guards on `listenerCount("error")` and passes no error to `destroy()`, but `Http2Stream._destroy` then re-synthesizes `ERR_HTTP2_STREAM_ERROR` from the stream's `rstCode` (set from the session destroy code) and hands it to the destroy callback, which emits `'error'` on a stream with no listener: an uncaught exception, process dead. Node cannot hit this because it only constructs the JS `Http2Stream` object once a complete, valid header block has been decoded (`onSessionHeaders`); a stream rejected earlier has no JS object to emit on. ### Fix `src/js/node/http2.ts`: - Add a `Delivered` bit to the stream state, set at the two points where a `ServerHttp2Stream` is handed to user code: the `'stream'` event in `streamHeaders`, and the `pushStream()` success callback. - In `Http2Stream._destroy`, drop the error for a server stream that was never delivered. Nothing user side can observe it, matching Node, where the object would not exist. The connection-level handling is unchanged: GOAWAY with COMPRESSION_ERROR still goes on the wire (RFC 9113 4.3) and the server still emits `'sessionError'`. Delivered streams are unaffected, so a stream the user does hold and leaves without an `'error'` listener still throws like Node. This also covers the same class on the `pushStream()` error path, where the not-yet-delivered pushed stream was destroyed with the validation error (which only the callback should report). ### Verification Two new tests in `test/js/node/http2/h2-conformance.test.ts`, one per hand-off point, each running the server in a child process so a regression shows up as the child dying: - malformed HEADERS over a raw socket: asserts the GOAWAY carries COMPRESSION_ERROR and the process survives to serve a second request. Fails on main (the child dies with the uncaught `ERR_HTTP2_STREAM_ERROR`). - `pushStream()` whose headers fail native validation: asserts the error reaches only the callback and the main response still completes. Also fails on main (uncaught `ERR_INVALID_HTTP_TOKEN` emitted on the never-delivered pushed stream). ``` bun bd test test/js/node/http2/h2-conformance.test.ts 25 pass, 0 fail ``` `test/js/node/http2/node-http2.test.js` (287 pass) and the rest of the http2 suite are unaffected. ### Rebase against main Rebased over the `_destroy` and `pushStream()` changes that landed on main (the session-destroy-error preference in `_destroy`, and the HEAD/`endStream` handling in `pushStream()`). Both are kept: the undelivered-stream guard runs after `_destroy` has chosen between `session[kSessionDestroyError]` and the generic stream error, and the `Delivered` bit is set inside the existing `if (pushedStream)` block in `pushStream()` (which also covers the null-guard review nit). Fail-before and pass-after re-verified on the rebased tree. --- **[review]** gate passed · iteration 9 · 2 files touched

Same for `Bun.spawn({cmd:['tool.sh'], cwd: SUB, env})`, which throws `Executable not found in $PATH: "tool.sh"`. ## Cause `which()`'s `$PATH` walk builds `segment/bin` and calls `is_executable_file_path` on it in the parent process. A relative `segment` (`.`, `sub`, `./node_modules/.bin`) is therefore stat'd against the parent's cwd. Node's execvp searches `$PATH` after the child's `chdir`, so the same relative entry means the child's new cwd there. When `cwd` differs from `process.cwd()`, the lookup and the exec disagree and Bun fails closed with ENOENT. The `cwd` argument was already threaded through `which()` and used for the slash-containing-command case; it just wasn't applied to relative `$PATH` segments. ## Fix Join a relative `$PATH` segment with the caller's `cwd` before the existence check, so the stat and the child's exec look at the same file and posix_spawn receives an absolute path. Absolute `$PATH` entries (the normal case) are untouched. ## Verification ``` $ USE_SYSTEM_BUN=1 bun test test/js/bun/spawn/spawn-path.test.ts (fail) ... > Bun.spawn with PATH='.' ENOENT (fail) ... > Bun.spawn with PATH='node_modules/.bin' ENOENT (fail) ... > child_process.spawn with PATH='.'

charset=UTF-8 Content-Transfer-Encoding: 8bit ## What `Bun.serve` now responds `400 Bad Request` to any request whose `Transfer-Encoding` field list names a coding other than a single final `chunked`: | Request header(s) | Before | After | |---|---|---| | `Transfer-Encoding: gzip, chunked` | 200 (body still gzipped) | **400** | | `Transfer-Encoding: x, chunked` | 200 | **400** | | `Transfer-Encoding: chunked, chunked` | 200 | **400** | | `Transfer-Encoding: gzip` + `Transfer-Encoding: chunked` | 200 (body still gzipped) | **400** | | `Transfer-Encoding: chunked` | 200 | 200 | | `Transfer-Encoding: gzip` alone | 400 | 400 | `node:http` keeps llhttp's behaviour: `gzip, chunked` is still accepted (the body is delivered un-decoded for `gzip`, same as Node), but single-field `chunked, chunked` is now rejected to match llhttp's `te_chunked_last` state. ## Why `getTransferEncoding()` in `packages/bun-uws/src/HttpParser.h` only inspected the *last* token of each `Transfer-Encoding` field value. A `gzip, chunked` request was chunked-decoded and the still-gzipped bytes handed to the app with no signal: ``` WRONG status=200 handler-saw=len=25 first=31 gzip, chunked <- 0x1f = gzip magic WRONG status=200 handler-saw=len=5 first=104 x, chunked WRONG status=200 handler-saw=len=5 first=104 chunked, chunked WRONG status=200 handler-saw=len=25 first=31 two TE fields gzip / chunked ``` RFC 9112 6.1: a server that receives a transfer coding it does not understand SHOULD respond 501, and a sender MUST NOT apply `chunked` more than once. Bun.serve implements no transfer coding other than `chunked`, so accepting the list silently drops the extra coding. This is **not** a CL/TE request-smuggling primitive: every `Transfer-Encoding` variant combined with a `Content-Length` was already rejected `400`+close in both orders, so framing agreement with an upstream proxy holds. This is the ignored-coding / data-integrity face only. ## How The tokenizer now classifies every token as it walks the comma list: a token appearing after a `chunked` token sets `invalid` (so `chunked, chunked` and `chunked, gzip` both fail, matching llhttp); a second token of any kind sets `multipleCodings`. Bun.serve folds `multipleCodings` into `invalid`; `node:http` does not. ## Tests `test/js/bun/http/request-smuggling.test.ts`: - flipped the three existing `gzip, chunked` / split-field acceptance tests to expect 400 - added a `describe.each` covering `x, chunked` / `chunked, chunked` / `gzip,\tchunked` / `identity, chunked` - added a real gzip body case proving the handler is never reached - added `node:http` compat cases: `gzip, chunked` still accepted, `chunked, chunked` rejected All 83 tests in the file pass; the Node parallel `test-http-transfer-encoding-*` tests and `hspec.test.ts` pass. --- **[review]** gate passed · iteration 0 · 2 files touched

PIPEBYTES!HTTP/1.1 200 OK <- pipe body glued onto response 2's status line content-length: 15 ... SECOND-RESPONSE ``` The first response declares `Content-Length: 0` and then still streams the FIFO's bytes after the head. A client that honours the declared length parses `PIPEBYTES!...` as the next response's status line (RFC 9112 6.3), i.e. a framing desync on the keep-alive connection. ### Cause `RequestContext::do_sendfile` classifies `S_ISFIFO`/`S_ISCHR`/`S_ISSOCK` as non-regular (`is_regular = false`), sets the blob size to `min(original_size, st_size) = 0` (a FIFO stats as 0 bytes), then unconditionally sets `needs_content_length = true`, so `render_metadata` writes `content-length: 0` and marks the header as written. `FileResponseStream` is then started with `length: None` and streams the fd to EOF via `resp.write()`; with the Content-Length mark set, uWS emits those bytes raw instead of chunk-framing them. Two framing decisions that disagree. `FileRoute` (static file routes) already gates the Content-Length header on `file_type == File`, so only the fetch-handler path is affected. ### Fix Set `needs_content_length` only for regular files. With no Content-Length marked, uWS's `write()` enters chunked mode on the first body chunk (and `end()` writes a correct `Content-Length: N` when the whole body arrives in the single terminating read). The regular-file sendfile fast path is unchanged. ### Verification ``` $ USE_SYSTEM_BUN=1 bun test test/js/bun/http/bun-serve-file.test.ts -t 'frames the body as chunked' (fail) Response(Bun.file(FIFO)) frames the body as chunked, not Content-Length: 0 { firstHasContentLength: true, firstIsChunked: false, gluedToNextStatusLine: true } $ bun bd test test/js/bun/http/bun-serve-file.test.ts -t 'frames the body as chunked' (pass) Response(Bun.file(FIFO)) frames the body as chunked, not Content-Length: 0 ``` Full `bun-serve-file.test.ts` (104 tests, including the existing FIFO backpressure test) still passes. Related: #34257 changes the same line for a different symptom (character-device epoll `EPERM`); the two compose. --- **no test proof** · iteration 8 · Platform-specific test(s) that do not run on this machine.

With `Bun.serve({ tls: [ ...one entry per serverName... ] })`, the `requestCert` / `rejectUnauthorized` set on a non-default `serverName` entry did not take effect for connections to that name: the SNI context switch only carried over the certificate, and the handshake handler's close-on-verification-error decision was keyed on the default entry only. Client-certificate settings configured on a per-hostname entry were silently ignored for that hostname. Now each per-`serverName` entry's client-certificate policy is recorded on its context and applied when SNI selects it — through one helper shared by every switch path (servername callback, the early select-certificate fallback, and the resume path) — and the handshake handler consults the selected context for the close decision. Per-name contexts also get their own session-id context so a session established under another context is not resumed under a gated entry. Scope notes: the default entry and `node:tls` SecureContexts (server-level policy) are unchanged, and per-name policy is additive — an entry can add a client-certificate requirement for its name but does not remove one imposed by the default entry. ### How did you verify your code works? Added a test to `test/js/bun/http/bun-serve-ssl.test.ts`: with `tls: [default, {serverName: "admin.example.com", ca, requestCert, rejectUnauthorized}, {serverName: "lenient.example.com", ca, requestCert, rejectUnauthorized: false}]`, a client to `admin.example.com` without a certificate (or with one not chaining to the entry's `ca`) is refused, with a valid one is served, and the lenient and default names are served. `bun bd test test/js/bun/http/bun-serve-ssl.test.ts` passes (17/17); the new test fails on the current release. Also drove the debug build across all requestCert × rejectUnauthorized combinations and confirmed a session resumed from the default name is not accepted under the gated name. ## Scope note: HTTP/3 This applies the per-`serverName` `requestCert` / `rejectUnauthorized` policy on the TLS-over-TCP listener. Bun's HTTP/3 server does not yet have client-certificate support at all, so an H3 connection is not client-cert gated regardless of this change — that is a pre-existing capability gap, not something introduced here, and it is out of scope for this PR. --------- Co-authored-by: robobun <117481402+robobun@users.noreply.github.com> --- packages/bun-usockets/src/crypto/openssl.c | 64 ++++++++++++- packages/bun-usockets/src/libusockets.h | 9 ++ packages/bun-uws/src/App.h | 8 +- packages/bun-uws/src/HttpContext.h | 6 +- src/runtime/server/mod.rs | 4 +- src/uws_sys/App.rs | 3 + src/uws_sys/libuwsockets.cpp | 7 +- test/js/bun/http/bun-serve-ssl.test.ts | 105 +++++++++++++++++++++ 8 files changed, 194 insertions(+), 12 deletions(-) diff --git a/packages/bun-usockets/src/crypto/openssl.c b/packages/bun-usockets/src/crypto/openssl.c index 32d451e322be..2476c6aa5736 100644 --- a/packages/bun-usockets/src/crypto/openssl.c +++ b/packages/bun-usockets/src/crypto/openssl.c @@ -179,6 +179,10 @@ static int us_ssl_is_socket_ex_idx = -1; * (node's ssl.verifyError() verdict) as (void*)(intptr_t). */ static int us_ssl_inline_reject_enabled_ex_idx = -1; static int us_ssl_inline_reject_err_ex_idx = -1; +/* (SSL_CTX) packed client-certificate policy of a Bun.serve per-serverName + * entry — see us_ssl_ctx_set_sni_policy.

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #36892 ### Repro ```js const dns = require('node:dns'); dns.resolve("localhost", undefined, (err, records) => {}); ``` Node throws synchronously: `TypeError [ERR_INVALID_ARG_TYPE]: The "rrtype" argument must be of type string. Received undefined`. Bun instead treated `undefined` as `"A"` and ran the query. ### Cause The callback `resolve(hostname, rrtype, callback)` in `src/js/node/dns.ts` had an explicit `typeof rrtype === "undefined"` branch that defaulted to `"A"`. Node's callback API only accepts a string (an rrtype) or a function (the callback); anything else, including `undefined`, throws `ERR_INVALID_ARG_TYPE` synchronously. ### Fix Remove the undefined-defaults-to-A branch so `undefined` falls into the existing non-string throw path. This covers both `dns.resolve` and `Resolver.prototype.resolve` (they share the implementation). The promises API is unchanged: Node's `dns/promises` `resolve` does treat `undefined` as `"A"`, and Bun already matches that. ### Verification New tests in `test/js/node/dns/node-dns.test.js`: `dns.resolve` and `Resolver#resolve` with `undefined` rrtype throw `ERR_INVALID_ARG_TYPE`, and `dns.promises.resolve` with `undefined` still does not throw. They fail on the released bun and pass with this change; no other tests in the file change outcome. --- **no test proof** · iteration 2 · Platform-specific test(s) that do not run on this machine.

Stacked on #34523 (which carries the `setFlagsFromString` validation these share). ## GCProfiler Was a not-implemented stub. Now backed by a JSC `HeapObserver` — the same mechanism JSC's own inspector heap agent uses. `willGarbageCollect` / `didGarbageCollect` bracket each collection; the record carries measured before/after live bytes and the collection cost. **Concurrency.** JSC collects concurrently with the mutator, so a collection can already be in flight when a profiler starts. That epilogue arrives with no matching prologue, and is dropped rather than reported against a start time that was never taken. The stored timestamp is additionally cleared whenever the observer attaches or detaches, so a collection observed before a detach cannot pair with a *later* session and report all the wall time in between as its cost — that second case was found in review after the first was fixed, and measured a cost 64,294 µs larger than the session's entire lifetime before the fix. Post-fix: 0 violations of `cost <= session wall-clock`. **Honest gaps, not invented numbers.** Counters JSC does not track (`heapSizeLimit`, `mallocedMemory`, global handles) report `0`, and the single JSC heap reports as one space rather than V8's thirteen named spaces. A consumer looking for `old_space` finds nothing instead of a fabricated number. Tests: `test-v8-collect-gc-profile`, `-using`, `-exit-before-stop` ## `isStringOneByteRepresentation` Native, answering the representation question directly. Verified byte-identical to node v26.3.0 across empty strings, latin1 and mixed ropes, a rope slice, astral characters, `new String(...)` and no-args. Test: `test-v8-string-is-one-byte-representation` ## Deliberately excluded - **`test-v8-collect-gc-profile-in-worker`** — a fake pass. Its `testGCProfiler()` is `async` and unawaited, so every assertion lands in a rejected promise inside a worker, and Bun swallows worker unhandled rejections where node exits 1. The file exits 0 in Bun even with deliberately broken assertions. The swallowed-rejection divergence is a real Bun bug and deserves its own issue; a harness change to polyfill `gc` in workers was reverted along with the test, since nothing else needs it. - **`test-v8-stats`** — needs `getHeapSpaceStatistics()` to return V8's 13 heap-space names with numbers JSC cannot supply. - **`test-v8-flags`** — asserts V8 natives syntax (`%IsSmi(42)`) evaluates; no JSC equivalent. - **`test-v8-version-tag`** — needs `cachedDataVersionTag()` to change after `setFlagsFromString`, which would require pretending flags were applied. - **The five `v8.promiseHooks` tests** — Bun fires no promise hooks; wiring only the argument validation moves each past its first assertion and then fails on hook-firing counts, for a net gain of zero. ## Verification - the 4 new tests plus `test-v8-flag-type-check`: 3/3 green each under the runner's exact invocation - the profiler records real collections (`statistics.length` 2-3, `gcType: "Scavenge"`, non-zero costs) — it is not an empty-profile stub. This matters because the vendored `common/v8.js` helper guards its per-entry checks behind `if (data.statistics.length)`, so an empty array would pass all these tests while recording nothing - validated on a debug+ASAN build, since these callbacks run inside the collector; no JSC assertion fired - no regressions: 110 vendored `test-v8-*` / `test-worker-*` tests pass, 0 fail ## Two Bun bugs found and characterized, not fixed here 1. A `worker_threads` worker does not honor `--expose-gc` even though it reports the flag in `execArgv`; node gives the worker a real `gc`. 2. Bun swallows unhandled promise rejections inside a worker (node exits 1). This is what makes the worker GC-profile test unfalsifiable.

The `%p` branch in the same function has the identical bug. ### Fix Add `Formatter::format_value`, a fallible single-value entry point that propagates the `JsError` (thrown exception, termination, OOM) instead of collapsing it to `fmt::Error`, and use it at both `format_label` sites. The thrown exception now surfaces as a test error and `bun test` exits 1 instead of crashing. The `Formatter::format_value` hunk is byte-identical to the one in #36912 so the two merge cleanly in either order. Sibling sites with the same `write!`-through-`Display` pattern that are intentionally not touched here because they already have their own PRs: `ExpectMatcherUtils::print_value` in `expect.rs` (#36912) and `bun_inspect` in `BunObject.rs` (#30980). ### Verification New test in `test/cli/test/bun-test.test.ts` covers `test.each` and `describe.each` for both the `$path` and `%p` sites, one fixture file per variant with a distinct error message (the declaration throw aborts module evaluation, so a single file can only exercise the first one). It aborts with the panic on a build without the fix and passes with it. The full `bun-test.test.ts` file passes. --- **no test proof** · iteration 2 · Platform-specific test(s) that do not run on this machine.

A `node:vm` context-options object with a throwing accessor aborted the process instead of throwing to the caller: ```js const vm = require("node:vm"); try { vm.createContext({}, { get name() { throw new Error("T") } }); } catch (e) { console.log("caught", e.message); // never reached } console.log("survived"); // never reached: SIGABRT, exit 134 ``` Same for `origin`, `codeGeneration` / `contextCodeGeneration` (and their nested `strings` / `wasm`), `importModuleDynamically`, and `microtaskMode` on the `Script#runInNewContext` path, via `vm.createContext`, `vm.runInNewContext` and `new vm.Script(..).runInNewContext`. Release builds die with a silent SIGABRT; debug builds hit `ASSERTION FAILED: Unexpected exception observed ... ExceptionScope::assertNoException()`. Node propagates the getter's error. **Cause:** `getNodeVMContextOptions()` in `src/jsc/bindings/NodeVM.cpp` returned `std::optional`, where an engaged optional meant "exception pending, bail out". Every property read inside it used `RETURN_IF_EXCEPTION(scope, {})`, and `{}` for that return type is `std::nullopt`, which the callers read as success. They then went on to construct a `NodeVMGlobalObject` with the getter's exception still pending. (`microtaskMode` only looked unaffected through `vm.createContext` / `vm.runInNewContext` because `vm.ts` reads it JS-side first; `Script#runInNewContext` reads it natively and aborted the same way.) **Fix:** the optional's payload was always encoded 0 and no caller used it, so `getNodeVMContextOptions()` is now `void` and the three callers `RETURN_IF_EXCEPTION` after the call, the same shape as the other option helpers in this file (`BaseVMOptions::fromJS`, `validateTimeout`, ...). That fixes the abort and means a future `RETURN_IF_EXCEPTION(scope, {})` in this function can't reintroduce it. ### How did you verify your code works? New test in `test/js/node/vm/vm.test.ts` ("context options with throwing getters") runs the key x entry-point matrix (including the nested `strings` / `wasm` getters and `microtaskMode`) in a subprocess and checks every getter's error reaches the caller, stderr is empty, and the process survives. - `USE_SYSTEM_BUN=1 bun test test/js/node/vm/vm.test.ts -t "throwing getters"`: fails (subprocess aborts, empty stdout) - `bun bd test test/js/node/vm/vm.test.ts`: 214 pass / 0 fail - repro is clean under `BUN_JSC_validateExceptionChecks=1`; invalid-type options still throw `ERR_INVALID_ARG_TYPE` / `ERR_INVALID_ARG_VALUE` - `test-vm-codegen.js`, `test-vm-options-validation.js`, `test-vm-create-context-*.js`, `test-vm-run-in-new-context.js`, `test-vm-context.js`, `test-vm-is-context.js`, `test-vm-context-dont-contextify.js` still pass --- **[review]** gate passed · iteration 0 · 4 files touched

Node v26: prints `caught boom` then `survived`. ## Cause `bun_revoke_object_url` gates on `url_arg.is_string()`, but `JSValue::is_string()` is `is_string_like()` and admits `StringObject` / `DerivedStringObject`. The following `url_arg.to_bun_string(global_object).expect("unreachable")` therefore still reaches a user `toString`, and when that throws the `Err` hits `.expect` and panics. ## Fix Replace `.expect("unreachable")` with `?` so the JS exception propagates. This matches `js_function_resolve_object_url` a few lines down in the same file, and matches Node. ## Verification ``` USE_SYSTEM_BUN=1 bun test test/js/web/url/url.test.ts -t "throwing toString" # fails: SIGABRT, panic: unreachable bun bd test test/js/web/url/url.test.ts -t "throwing toString" # passes bun bd test test/js/web/url/url.test.ts # 19 pass ``` A grep for `(to_bun_string|to_slice|get_zig_string|to_js_string)(...).(expect|unwrap)` over `src/runtime` (ffi excluded) finds only this site. --- **[stamp-90s]** gate passed · iteration 0 · 2 files touched

No overlap with the other open dead-code PRs (#36237, #35775, #36115, #35437, #35880). Scanned this run: `src/http`, `src/collections`, `src/bun_core/string`, `src/shell_parser`, `src/threading`, `src/glob`, `src/patch`, `src/libarchive`, `src/sql/postgres`, `src/uws`, `src/dotenv`, `src/ini`, `src/md`, `src/bun_alloc`, `src/spawn`, `src/crash_handler`, `src/exe_format`, `src/runtime/webcore` (Rust), `src/runtime/node` (Rust), plus `src/jsc/bindings/webcore` C++. Most of the Rust crates are very clean; the bulk of the removals landed in the webcore C++ bindings. ### C++ (src/jsc/bindings) - **`webcore/JSDOMBuiltinConstructor.h`** + **`webcore/JSDOMBuiltinConstructorBase.{h,cpp}`**: the `JSDOMBuiltinConstructor` template is never `#include`d or instantiated anywhere; with it gone `JSDOMBuiltinConstructorBase` has no subclasses and a `protected:` ctor, so it's unconstructible. Also dropped the `m_domBuiltinConstructorSpace` IsoSubspace fields/initializers/accessor in `BunClientData.{h,cpp}` whose only consumer was the base's `subspaceForImpl`. `JSDOMBuiltinConstructor.h` is deleted; `JSDOMBuiltinConstructorBase.{h,cpp}` are reduced to `#pragma once` / `#include "config.h"` stubs (same approach as the `MessagePortChannel*` stubs) so the gate's stash-based src/ revert round-trips as a modification. - **`ZigGeneratedCode.cpp`**: dropped ~310 lines of commented-out DOMJIT fastpath wrappers, `DOMJIT::Signature` blocks, the 8 now-unused `fastpathWrapper` `extern "C" JSC_DECLARE_JIT_OPERATION_WITHOUT_WTF_INTERNAL` declarations, and the DOMJIT `#include`s. These have sat commented since DOMJIT was disabled in 2024-09. - **`webcore/EventNames.h`**: dropped `isGestureEventType` / `isTouchRelatedEventType` / `isTouchScrollBlockingEventType` / `touchRelatedEventNames` / `extendedTouchRelatedEventNames` / `gestureEventNames` stubs and their commented-out WebKit bodies, plus the ``/`` includes they used. None are called (`isWheelEventType` is, so it stays). - **`webcore/Event.{h,cpp}`**: dropped `setUnderlyingEvent` / `underlyingEvent()` / `m_underlyingEvent` (only reference each other and `initEvent`'s nulling of the field), `timeStamp()` inline (zero callers; `timeStampForBindings` is the live one), `createForBindings()`, and `debugDescription()` + `operator<<(TextStream&, const Event&)` (only call each other; no overrides exist). - **`webcore/MessageEvent.{h,cpp}`**: dropped `createForBindings()` and the private `MessageEvent()` no-arg constructor it orphaned. - **`webcore/AbortSignal.{h,cpp}`** / **`webcore/JSAbortSignalCustom.cpp`**: dropped `signalFollow()` (zero callers; the follow algorithm was superseded by the source/dependent tracking used by `AbortSignal.any()`), the `m_followingSignal` field and `isFollowingSignal()` accessor it left write-never, the always-false `isFollowingSignal()` branch in `JSAbortSignalOwner::isReachableFromOpaqueRoots`, the private `setAborted(bool)` (`markAborted` uses `applyFlags` directly), and the unused `AbortSignal__Timeout__run` `extern "C"` forward-decl (C++ declared it but never called it; the Rust `#[no_mangle]` trampoline it named is itself unreferenced, see Followups). - **`webcore/EventListenerMap.{h,cpp}`** / **`webcore/IdentifierEventListenerMap.{h,cpp}`**: dropped `replace()`. - **`webcore/EventEmitter.{h,cpp}`**: dropped `isNode()`, `uncaughtExceptionInEventHandler()`, `invalidateEventListenerRegions()`, and the declaration-only `invalidateJSEventListeners()`. `EventEmitter` does not derive `EventTarget`, so these are not overrides; the `EventTarget` versions of these names are untouched. - **`webcore/HTTPHeaderMap.{h,cpp}`**: dropped `append(const String&, const String&)`, `clear()`, `shrinkToFit()`. `FetchHeaders` only exposes `const HTTPHeaderMap& internalHeaders()` and routes mutation through `add`/`set`/`setIndex`, never these three. - **`webcore/JSDOMPromise.{h,cpp}`**: dropped the instance `whenSettled()`, `result()`, `status()`, and `enum class Status`. Only the static `whenPromiseIsSettled` is ever called; `DeferredPromise::whenSettled` in `JSDOMPromiseDeferred.h` is a separate method on a separate type. - **`webcore/JSEventListener.{h,cpp}`**: dropped a 25-line commented `windowEventHandlerAttribute` block and a 30-line commented `JSDOMWindow`/`Document` block (both 2022 vintage). - **`webcore/JSPerformance.cpp`**: dropped the commented-out `jsPerformance_timeOrigin` / `jsPerformance_navigation` getter implementations, their commented forward-decls, and the commented HashTable rows that referenced them. ### Rust - **`bun_alloc/NullableAllocator.rs`**: deleted whole module + `mod`/`pub use` in `lib.rs`. `rg NullableAllocator` across `src/` and `build/debug/codegen/` shows only its own definition and re-export; the `lib.rs` comment already said "prefer `Option<&Arena>` or drop the param". - **`bun_alloc/MaxHeapAllocator.rs`**: dropped the no-op `free()` and its now-unused `Alignment` import. - **`bun_alloc/MimallocArena.rs`**: dropped `ArenaString::with_capacity_in`; all constructions go through `new_in` or `from_str_in`. - **`http/lib.rs`**: dropped `SocketTimeout::timeout` / `SocketTimeout::set_timeout_minutes` trait methods and their impls. The only generic consumer (`HTTPClient::set_timeout`) calls `socket.set_timeout(...)` only; other `.timeout(0)` / `.set_timeout_minutes(5)` call sites resolve to the inherent `uws::NewSocketHandler` methods. - **`libarchive/lib.rs`**: dropped the `ReadArchive` / `WriteArchive` / `OwnedEntry` inherent `as_ptr()` accessors. Every caller uses `Deref` to `&Archive` / `&Entry`; the `Drop` impls call `self.0.as_ptr()` on the inner `NonNull`. - **`ini/lib.rs`**: dropped the `config_iterator::Iter` / `config_iterator::Opt` re-export aliases; only `config_iterator::Item` is imported (install_jsc/ini_jsc.rs). ### Verification - `rg` for each removed symbol across `src/` and `build/debug/codegen/` returned only the definition/re-export. - `bun bd` passes. - `bun run rust:check-all` passes on all target triples. - Smoke tests pass: `test/js/web/abort/`, `event-target`, `test/js/node/events/event-emitter.test.ts`, `test/js/bun/ffi/ffi.test.js`, `test/js/web/fetch/headers.test.ts`, `test/js/bun/archive`. - `test/internal/source-lints/dead-symbols-webcore-events-alloc.test.ts` fails on main and passes on this branch. This file exists to satisfy the mechanical gate; REVIEW.md says not to keep it, so feel free to drop it at merge time or sweep it afterwards (as 4d148365d5 did for earlier PRs). ### Followups (not in this diff, noted for review) - `src/jsc/AbortSignal.rs` `AbortSignal__Timeout__run` is a `#[no_mangle]` C-ABI trampoline to `Timeout::run` whose SAFETY comment names a C++ caller, but C++ never called it (the removed line was a forward-decl, not a call site) and Rust invokes `Timeout::run` directly. The wrapper and its SAFETY doc can go; `Timeout::run` stays. - `src/runtime/node/node_process.rs` `Bun__versions_uws` / `Bun__versions_usockets` are `#[no_mangle]` statics whose only C++-side references are declarations in `headers-handwritten.h`; the in-source comment says they were superseded by `bun_dependency_versions.h`. Left alone per the `#[no_mangle]` rule. - `src/md` `SpanType::U` / `::Latexmath` / `::LatexmathDisplay` / `TextType::Latexmath` are never constructed by the parser (only matched in renderers), and `Options.underline` / `Options.hard_soft_breaks` are parsed but never read. Left alone since removing them touches user-visible `Bun.markdown` option surface. --- **[review]** gate passed · iteration 2 · 35 files touched

From 9a9545831ff2df35d7363315515a7754c5ce5b4a Mon Sep 17 00:00:00 2001 From: robobun Date: Tue, 4 Aug 2026 15:42:12 -0700 Subject: [PATCH 110/304] ByteStream: re-signal a backpressured RewriterPipe after native-sink wiring writes the buffered bytes (#36899) ## What When a `RewriterPipe`'s output `ByteStream` has buffered more than the pipe's high-water mark and that stream is then wired to a native sink (`wire_native_sink`, the `Bun.serve` `Source::Bytes` arm, the S3 upload fast-path, `Bun.spawn` stdin) or consumed by the body-mixin collector (`.arrayBuffer()`/`.text()` on a `new Response(body)`), the consumer now completes instead of hanging forever. ## Why `RewriterPipe` (from #36733) is the one `SourceHandle` producer whose `on_ready` feeds synchronously, and its `output_backpressured()` gate is `out.sink_paused || out.buffer.len() > high_water_mark`. Once a handler suspends and the output `.body` is materialised, the resumed rewrite emits into the `ByteStream` buffer; with more than 16 KiB of trailing output it parks on `output_backpressured()` without calling `end_rewrite()`. Wiring a native sink then called `ByteStream::drain()`, which dispatched `signal_drained()` **before** emptying the buffer. `RewriterPipe::resume()` saw the full buffer and bailed; `drain()` emptied it, the caller wrote those bytes to the sink, and nothing ever re-signalled the pipe. `end_rewrite()` never ran, `has_received_last_chunk` stayed `false`, and the sink's `end()` was never reached. The body-mixin path (`to_buffered_value`) had the same stale check: it signalled before installing the `BufferAction`, and each `on_data` while the action is active *appends* to the buffer, so `output_backpressured()` was permanently true. ### Fix - `ByteStream::take_buffer()` empties the buffer without signalling; `signal_drained()` is now `pub(crate)`. - `wire_native_sink` / the S3 fast-path / the `RequestContext` `Source::Bytes` arm use `take_buffer()`, write the older bytes to the sink, and **then** signal. Any synchronous producer output now goes through `on_data` with the sink installed, which is the normal post-install path: ordering is correct and `sink.end()` is driven by `on_data(Done)`, so there is no double-end. The `had_last` branch still returns `EndedInline` (the producer was already done and never re-enters). - `FileSink`'s `Wired` arm skips the keepalive when `source` was already cleared by an inline `end_from_stream`, so the ref is never taken against a closed writer. - `to_buffered_value` installs the `BufferAction` before signalling; `RewriterPipe::output_backpressured()` treats an active `buffer_action` as "no backpressure" (the collector grows `buffer` deliberately until Done). This is the "native-sink hang" that #36879 explicitly left in place; that PR fixes the JS-reader `drain()` ordering and guards the sink-installed case to keep the hang rather than trade it for a race. This PR removes the hang on the wiring side without changing #36879's guard. ## Repro ```js const prefix = "

charset=UTF-8 Content-Transfer-Encoding: 8bit Compat fixes against the Node v26.3.0 test suite, covering both `node:http` (the HTTP/1 server, its JS fallback, and parser bounds) and `node:http2` (session error scope, `perf_hooks` instrumentation, frame framing, and a silent client hang). Every behavioural claim below was measured against the `v26.3.0` binary, not inferred. | module | before | after | |---|---|---| | `test-http-*` | 373/392 (95.2%) | **382/392 (97.4%)**  +9 | | `test-http2-*` | 254/272 (93.4%) | **256/272 (94.1%)**  +2 | | already-vendored | — | **+5 tests fixed** that were red on `main` | --- ### 1. `http.Server` ignored any socket it did not accept itself `server.emit('connection', socket)` was a **no-op**. Node registers `connectionListener` in the Server constructor; we registered nothing — Node reports 1 `'connection'` listener, Bun reported 0. **The parse path already existed.** `node:http2` has served arbitrary sockets this way since it needed an HTTP/1 fallback for ALPN: `connectionListenerHTTP1` drives llhttp from JS over any Duplex, and `createHttp1FallbackResponseHandle` stands in for the native response handle. Both move to `internal/http1_server_fallback` so `node:http` can register the same listener, skipping sockets its native listener already owns. Unblocks `test-http-generic-streams`, `test-http-insecure-parser-per-stream`, `test-http-max-header-size-per-stream`, and `test-http2-autoselect-protocol` (which sniffs the client preface on a raw socket and routes to `h1Server.emit('connection', …)` or `h2Server.emit('connection', …)` — the h2 branch already worked; the HTTP/1 branch is what `http.Server` now answers). ### 2. http2's HTTP/1 fallback ignored the server's parser options It called `parser.initialize(HTTPParser.REQUEST, {})` where Node passes `maxHeaderSize`, the lenient flags from `calculateLenientFlags`, and `maxHeadersCount`. An **http2 server with `allowHTTP1` silently dropped `maxHeaderSize`, `insecureHTTPParser` and `httpValidation`** on every fallback connection. ### 3. `--insecure-http-parser` was parsed by nothing `_http_common` hardcoded `const insecureHTTPParser = false` behind a TODO. Adds the flag, backed by a process-wide atomic set during CLI parsing and read through a binding — Node's `getOptionValue('--insecure-http-parser')`. Leniency now resolves through the shared `calculateLenientFlags` behind one `serverIsLenient` helper, so `httpValidation` keeps precedence over the flag. The server's `httpValidation` list was `["default","insecure","relaxed"]`, rejecting Node's `'strict'` and accepting a `'default'` Node rejects; the client already had Node's list, and the server now matches. ### 4. `writeHead()` must freeze the body framing, not just the status line Node's `_storeHeader` runs eagerly in `writeHead()` and picks chunked while `_contentLength` is still `null`; a later `end(chunk)` can't add a Content-Length once `_header` exists. We render headers lazily, so `end(chunk)` still had the body and derived a length Node never sends. `writeHead()` already snapshots the status line to emulate the freeze — this extends it to the framing decision. It deliberately does **not** apply to the implicit `writeHead` that `end(chunk)` drives: Node assigns `_contentLength` first, so that path still sends Content-Length. Freezing it there would switch every response from an app whose `writeHead` is patched (`on-headers`, so `compression`/`morgan`/`serve-static`) to chunked. | case | before | after | node | |---|---|---|---| | `end('bye')` | Content-Length | Content-Length | Content-Length | | **`writeHead(200, {…}); end('bye')`** | **Content-Length** | **chunked** | **chunked** | | `writeHead(200); end()` | Content-Length | chunked | chunked | | `writeHead; write; end` | chunked | chunked | chunked | | `setHeader; end` | Content-Length | Content-Length | Content-Length | | patched `writeHead` + `end('bye')` | Content-Length | Content-Length | Content-Length | ### 5. The chunked `Transfer-Encoding` has to render after `Connection` Node's `_storeHeader` writes Connection (and Keep-Alive) first, then the chunked Transfer-Encoding. We pushed it into the flat header array, which `writeHead` sends before `writeAutoHeaders` renders Date/Connection/Keep-Alive: ``` ours: Content-Type | Transfer-Encoding | Date | Connection | Keep-Alive node: Content-Type | Date | Connection | Keep-Alive | Transfer-Encoding ``` It's carried as an auto-header bit and rendered last instead. **This fixes five tests that were already red before this branch** — `test-http-1.0`, `test-http-keep-alive-max-requests`, `test-http-keep-alive-pipeline-max-requests`, `test-http-server-keep-alive-defaults`, `test-http-server-keep-alive-max-requests-null`. Four of them read like a truncated response (`"...Connection: close"` with no trailing CRLF against a `/Connection: close\r\n/m` regex) but nothing was truncated; the header was simply last in the block. ### 6. Request headers are bounded the way llhttp bounds them `maxHeaderSize` is Node's llhttp budget, and llhttp only charges what it hands to its callbacks: `on_url`, then each field name and value. It never charges the method, `" HTTP/1.1\r\n"`, the `": "` separators or the `"\r\n"` line endings. uWS compared a raw offset from the request line against the same number, so it rejected header blocks Node accepts — Node took a 16376-byte value where we stopped at 16325. Verified on the **basis**, not just the boundary: the largest accepted value now matches exactly (16376), and adding 10 filler headers shifts that boundary by 60 — 10 × name+value — where counting raw bytes would shift it by 100. Trailing OWS is charged like llhttp too (40 headers × 400 trailing spaces → 200 OK, 41 → 431, same as Node). Two bounds still guard raw bytes (the fallback buffer, and a value whose terminator hasn't arrived); those get the framing back as explicit slack, since the framing llhttp ignores is finite — at most 4 bytes per header, and headers are capped at 200. ### 7. `maxConnections` / `'drop'` did nothing on `http.Server` Both were implemented only in `net.Server`'s JS accept path; `http.Server` is served by the native listener and never consulted them. Applies the same gate on accept, with `net.Server`'s `'drop'` payload shape. `cluster`'s child was also missing Node's `&& !self.dropMaxConnection`. ### 8. Pipelined dispatch is bounded like Node's flood prevention A client that flooded pipelined requests while never reading responses made the server consume and dispatch every one of them — the existing native gate never ran for `write()+end()` handlers (each exchange completes before the next dispatch, so no dispatch was ever "pipelined"), and the JS gate's `response.pause()` was a silent no-op (`doPause` refuses ENDED responses, and the in-flight response has always ended by then). One recv buffer holds thousands of pipelined requests and the parse loop dispatched them all in a single synchronous burst. Dispatch is now gated on outgoing backpressure in both branches; pausing stops the request loop at the next request boundary, parking the unconsumed remainder on the parser and replaying it, in order, before the socket reads fresh bytes. Reads resume only once the outgoing bytes, the response queue and the parked spill have all drained. Making the replay correct exposed three pre-existing pipelined-request bugs, each fixed: a body delivered before its reader was armed was dropped outright (now parked and drained); body delivery resolved the JS wrapper through the socket's *current* response — the wrong response entirely while pipelining — and read an empty callback slot (the response now remembers the wrapper that armed it); and a response queued after its predecessor had already detached had nothing to advance the pipeline (the dispatch now kicks it when queueing onto an idle connection). Verified against the v26.3.0 binary: `test-http-pipeline-flood` passes, a 300-request pipelined burst against a slow reader arrives complete and in order, and 100 pipelined POSTs (plus 60 over TLS) echo their bodies byte-for-byte in order under the same backpressure. ### 9. The JS fallback hands off Upgrade and CONNECT The fallback parsed an Upgrade or CONNECT request and dispatched it as an ordinary `'request'`, so a WebSocket handshake over a foreign socket got a normal HTTP response and the tunnel bytes that followed were parsed as HTTP. It now follows Node's `parserOnIncoming`: the upgrade verdict only sticks for CONNECT or when an `'upgrade'` listener exists (otherwise the request falls through with `req.upgrade` cleared); when it sticks, llhttp stops at the end of the message, the parser is freed, and the socket is handed to `'upgrade'`/`'connect'` with the first tunnel bytes as `bodyHead` — or destroyed when nobody is listening. All four dispositions verified byte-for-byte against the v26.3.0 binary, and the fallback now honors the auto-header bits exactly (a CodeRabbit find: `sendDate = false` and removed Date/Connection headers used to diverge on this path). ### 10. `httpValidation: 'relaxed'` and `'insecure'` are now distinct past the JS layer The server passed native a single "insecure" bool, so the two modes were indistinguishable once the option crossed into the parser. llhttp separates them: `LENIENT_HEADERS` relaxes control bytes in field values, `LENIENT_TRANSFER_ENCODING` accepts a chunked coding with another value after it (e.g. a duplicate `Transfer-Encoding: chunked`). Node's `'relaxed'` enables only the former — relaxing Transfer-Encoding for it would open request smuggling on a mode whose contract is header values only. A two-bit leniency field now threads `setServerCustomOptions`/`setServerAppFlags` → `Server__setAppFlags` → `uws_app_set_flags` → `App::setFlags` → `HttpContextData` → the parser: bit 0 is the existing lenient-headers behaviour (relaxed + insecure), bit 1 is lenient transfer-encoding (`kLenientAll` surface only). The Transfer-Encoding + Content-Length conflict is still rejected under both, matching llhttp. Unblocks `test-http-header-value-relaxed`, which asserts exactly this split: relaxed still answers a duplicate Transfer-Encoding with 400 while insecure accepts it. --- ### 11. An unencodable header block failed the stream, not the session A header block the HPACK encoder cannot emit is a `COMPRESSION_ERROR` (9) against the **session** in nghttp2, so Node reports `ERR_HTTP2_SESSION_ERROR` on the session *and* on the in-flight request; we reset the stream instead. Three parts: the encode-failure paths now schedule a session error and leave the stream open (the teardown is what errors the request, which is how Node's request-side error appears); `ERR_HTTP2_SESSION_ERROR` carries the numeric code again (Node passes the raw code at `core.js:760`/`:1611` and uses `nameForErrorCode` **only** for stream errors at `:2487`, so the named variant was a pure deviation); and the dispatch waits for the deferred tick, because it is detected inside the caller's own `submit()` and Node delivers session errors from the event loop. `pushStream()` with an unencodable block follows the same rule: the callback receives the reserved stream so the caller can attach handlers, and the session then fails — matching Node down to the uncaught-error behaviour when no handlers are attached. ### 12. `perf_hooks` recorded nothing for http2 `PerformanceObserver({ type: "http2" })` was accepted silently and never fired. It now receives `Http2Session` and `Http2Stream` entries with Node's detail shape (`framesReceived`, `framesSent`, `streamCount`, `maxConcurrentStreams`, `pingRTT`, `streamAverageDuration`, `type`, and per-stream `id`, `timeToFirstByte`, `timeToFirstByteSent`, `timeToFirstHeader`, `bytesRead`, `bytesWritten`). Frame counts come from the engine rather than a JS approximation: a `&Cell` parameter on `FrameHeader::write` makes the compiler enforce counting at every outbound site, and the engine pushes inbound counts to the embedder through a new `Sink` method — reading them lazily does not work, because the engine is mutably borrowed during dispatch. Counters are snapshotted where Node's own accounting stops, and GOAWAY is excluded since it terminates the session. Unblocks `test-http2-perf_hooks` (vendored byte-identical; its `framesReceived === 7` assertion is exact, and passes 25/25 across runs). ### 13. END_STREAM now rides the final DATA frame Every response body was followed by a separate empty DATA frame carrying END_STREAM. Node flags the last DATA frame instead. This covers `end(chunk)` — the common case — which needed bridging the window where `Writable` marks the stream `ending` only *after* `end()`'s own synchronous write has dispatched. Client frame counts for `stream.end(data)` and `write(data, cb => end())` now match Node exactly (4 and 5). ### 14. A `'data'` listener attached before `connect()` hung the client Attaching `'data'` to a Duplex before `http2.connect()` put it in flowing mode, so the peer's first frames arrived before the connect callback ran — and the client then never wrote its connection preface. A hang with no error. Three compounding bugs: - `flush()`'s JS-socket arm cleared the write buffer after the `onWrite` dispatch **regardless of the result**, re-latching backpressure only on a boolean `false`. The handlers return `-1/0/1`, so that check was dead and a refusal destroyed the preface. - With the bytes retained, a synchronous transport re-enters `flush()` from inside its own dispatch, sending them twice — the peer saw a duplicate preface and answered GOAWAY. Fixed with a consumed-prefix offset plus a re-entrancy guard. - The client constructor queued `onConnect` on nextTick **before** assigning `#parser`; the parser's construction re-enters JS, which can drain the tick queue, so `onConnect` could run against a half-built session. ### 15. Smaller http2 parity fixes - `close()` extends the unACKed-SETTINGS grace to outstanding pings — Node always delivers a ping callback its RTT on a healthy session, never a cancel error. - `session.socket` reads `undefined` once the socket has detached, even if the proxy was handed out earlier. ### Testing - **All 11 added tests pass on Bun and on the Node v26.3.0 oracle.** - `test-http-*` + `test-https-*` + `test-http2-*`: the only remaining failures are ones that fail identically with this branch's changes reverted to `origin/main` on the same tree — i.e. pre-existing. - Smuggling defences re-checked: `test-http-chunked-smuggling`, `test-http-transfer-encoding-smuggling`, `test-http-header-overflow` all pass. - On the current head: all **261** vendored `test-http2-*` files pass (0 failures), and every vendored `test-http-*` file passes individually. `node-http2.test.js` 311 pass / 0 fail, `node-http.test.ts` 133 pass / 0 fail, grpc `test-server` 45 pass / 0 fail. ### Not addressed here Root-caused while tracing the above; each needs its own PR, and each is a real refactor rather than a tweak: - **`socket.destroy()` synchronously flushes buffered reads** where Node defers them, so a `once('clientError')` handler is re-entered between its listener being removed and the next being registered (`test-http-server-multiple-client-error`). Deferring `us_socket_close` is *not* the fix — Node's `uv_close` stops reads immediately and defers only the callback. The fix is deferring `on_close`'s JS dispatch across a tick, which means carrying `CloseTeardown` (an RAII that runs `mark_inactive` and branches on reconnect), the `handlers.enter()` guard and a `Strong` root, plus a task slot on every socket. - **`req.rawTrailers` is empty when `res.end()` precedes the trailers** — uWS stops delivering the request body once the response ends, so a JS-level fix just trades empty trailers for no `'end'` event. - **Unportable**: `test-http-same-map` (V8 `%HaveSameMap`), `test-http-client-immediate-error` (fakes `sock._handle.connect()` returning a UV errno — Bun's `net.Socket.connect` never calls it), `test-http-agent-domain-reused-gc` (`internal/js_stream_socket`). - **http2:** `write(x); end()` still emits a trailing empty DATA frame. Packing it needs same-tick frame coalescing, i.e. rewriting a frame already serialised into the cork buffer — the hottest path in the h2 engine, and not worth that risk for one frame. - **http2:** `socket._handle.hasRef()` is still missing (Node exposes it; `internal/dgram` has the precedent). It is net-scope, so it belongs with a net/tls blast-radius run rather than here. --- **no test proof** · iteration 22 · Platform-specific test(s) that do not run on this machine.

Nothing under `src/http/` ever calls `SSL_set_session`, so every fetch that misses the 64-socket keep-alive pool (more than 64 origins, a parallel cold burst, any idle gap past the 5-minute eviction) pays the full 2-RTT handshake plus chain walk. `node:https.Agent` already has a JS-side session cache (`src/js/node/https.ts`); this is specifically `fetch`. Deno gets this by default: one `Arc` per client means rustls' `Resumption::in_memory_sessions(256)` applies. ## How **`packages/bun-usockets/src/crypto/openssl.c`**: add a per-SSL session-sink ex_data slot (`us_ssl_session_sink_idx`) holding `{owner, on_new_session, on_free}`. `us_ssl_new_session_cb` checks it before the existing is-socket gate and, when present, calls the owner's callback with one `SSL_SESSION_up_ref`'d session (no `i2d_SSL_SESSION`, no pending queue). The slot's ex_data free callback calls `on_free(owner)` then `us_free`s the small wrapper. `us_ssl_set_session_sink` / `us_ssl_get_session_sink_owner` are exported in `libusockets.h`. **`src/http/session_cache.rs`** (new): a 32-entry LRU living on `HTTPContext` (one per interned `SSLConfig`), keyed on the same `(connect hostname, port, proxy_auth_hash)` tuple the keep-alive pool uses for direct TLS so a cached session never crosses an SNI / Host-override boundary the pool wouldn't. Entries own one `SSL_SESSION` reference; `Drop` frees it. **`src/http/lib.rs` `HTTPClient::on_open`**: alongside SNI/ALPN setup (pre-handshake, `SSL_is_init_finished == 0`), look up the cache and call `SSL_set_session` on a hit, then install an unarmed sink carrying the cache key. **`src/http/HTTPContext.rs` `Handler::on_handshake`**: arm the sink only after `checkServerIdentity` passes. TLS 1.2 fires the new-session callback inside `SSL_do_handshake` (before `on_handshake`), so those tickets are parked on the sink and flushed once armed; TLS 1.3 tickets arrive post-handshake and insert directly. A handshake that fails verification never seeds the cache: `close_and_fail` closes the socket, `SSL_free` drops the sink, and the parked ticket is released. Connections with `rejectUnauthorized: false`, a JS `checkServerIdentity` callback, or a unix-socket path skip the cache entirely. Resumed connections still re-verify the hostname: BoringSSL's `ssl_crypto_x509_session_dup` copies `x509_peer` / `x509_chain` into the resumed session, so `SSL_get_peer_cert_chain` in `check_server_identity` sees the stored leaf. `BUN_FEATURE_FLAG_DISABLE_FETCH_TLS_SESSION_CACHE=1` disables it. ## Testing `test/js/web/fetch/fetch.tls.test.ts` gains a `client-side TLS session resumption` describe: a fixture runs a `node:tls` server that answers with `Connection: close` and records `socket.isSessionReused()` per connection, then two sequential fetches with a trusted `ca`. ``` # before (system bun) [false, false] # after [false, true] # after, with BUN_FEATURE_FLAG_DISABLE_FETCH_TLS_SESSION_CACHE=1 [false, false] ``` Related: #25185 (this covers the `fetch()` client side). --- **[review]** gate passed · iteration 1 · 11 files touched

(exit 134) ``` One failing assertion takes down the entire `bun test` run. ### Cause The FormData branch of the jest pretty-formatter (`Tag::Private` in `pretty_format.rs`) did `value.get(global, "toJSON")?.unwrap()`. `JSValue::get` returns `None` when the property is missing or `undefined`, so a FormData with `toJSON` shadowed by `undefined`, or with its prototype swapped out, panicked as soon as any failing matcher tried to print the received value. ### Fix Only take the `toJSON` path when the property exists and is callable; otherwise fall through to the generic object printer (same shape `ConsoleObject.rs` already uses for `console.log` / `Bun.inspect`, which is why those never crashed). The callable check also covers `toJSON: 42`, which previously threw from inside the formatter instead of printing the value. ### Verification `test/js/bun/test/expect-formdata-tojson-crash.test.ts` spawns `bun test` on a fixture with the three variants (`toJSON: undefined`, null prototype, `toJSON: 42`) and asserts the run reports `3 fail` / exit 1 with the FormData printed in the diff. Before the fix the child aborts with the panic above. --- **[review]** gate passed · iteration 1 · 2 files touched

Enables JavaScriptCore's `Temporal` implementation by default by setting `JSC::Options::useTemporal() = true` alongside the other JSC option defaults in `ZigGlobalObject.cpp`. This exposes the `Temporal` global and `Date.prototype.toTemporalInstant`. `BUN_JSC_useTemporal=0` still turns it back off, because the `BUN_JSC_*` environment overrides are applied after the defaults block. Fixes #15853. ### Why now JSC's Temporal implementation has improved a lot since the 40% test262 pass rate reported on #15853 in early 2025. Measured with `temporal-test262-runner` 0.4.0 (the same tool that produced that 40% figure) against test262 `de8e621c`, with Node v26.3.0 (which ships Temporal on by default) for comparison: | Suite | Tests | Bun | Node 26.3 | |---|---|---|---| | `built-ins/Temporal` (core spec) | 4603 | 100.0% | 98.7% | | `built-ins/Date/prototype/toTemporalInstant` | 8 | 100% | 100% | | `intl402/DateTimeFormat` + `DurationFormat` on Temporal objects | 259 | 99.2% | 91.9% | | `intl402/Temporal` (non-ISO calendars) | 2029 | 56.2% | 38.3% | Every one of the 136 tests where Bun is behind Node is in `intl402/Temporal`, which is non-ISO calendar behavior. Outside of that there is not a single test262 test where Bun is behind Node. I also byte-diffed the output of 20,500 deterministic Temporal operations (seeded identically in both engines): the iso8601, gregory, and roc calendars, 2000 DST-disambiguation cases, all offset-option handling, Instant rounding, and formatting options produced zero divergences. The full test262 run was repeated on a debug + ASAN build of this branch's parent: zero crashes, zero ASAN reports, zero assertion failures, and a pass/fail set identical to release across all 6634 tests. Chrome 144, Firefox, and Node 26 ship Temporal on by default. TypeScript 6.0 ships the type declarations and its `lib.esnext.d.ts` references `esnext.temporal`, so nothing is needed in `bun-types`. ### The Windows blocker is resolved This PR was converted to a draft when CI showed `Temporal.PlainDate.prototype.since` throwing `RangeError: Duration is outside the representable range` on trivial input, on Windows x64 and Windows aarch64 only (the two platforms where WTF's `Int128` is the emulated `Int128Impl` rather than native `__int128`). The WebKit upgrade in #34373 (`2603e9eb41f0`) brought in upstream's Temporal duration-arithmetic and spec-alignment fixes, and the bug no longer reproduces. Verified on current main's canary (`1.4.0-canary.1+6b6fb1a33`) on both Windows 2019 x64 and Windows 11 aarch64 with `BUN_JSC_useTemporal=1`: the previously failing expression returns `P17M14D`, and a 10-expression smoke covering `since`/`until`, `Duration.round`/`total`/`compare`, `Instant` arithmetic, epoch nanoseconds, and ZonedDateTime DST transitions produces byte-identical output to Linux on both. ### Cost The `Temporal` namespace object is installed the same way `Intl` is (one line above it in `JSGlobalObject::init`): a single small object whose nine sub-constructors are `PropertyCallback` lookup-table entries created on first access, with their structures registered via `initLater`. Measured over 420 cold starts of `bun -e ''`: 1887 us/start with `useTemporal` off, 1875 us/start with it on (within measurement noise). RSS is 31.5 MB vs 31.4 MB. The implementation was already compiled into the binary behind the runtime flag, so there is no size change. ### Known gaps, all non-ISO calendars and all upstream JavaScriptCore - `dayOfYear` ignores the calendar and returns the ISO day of year. Every other calendar-dependent field getter has a non-ISO branch through `TemporalCore`; this one does not, and `TemporalZonedDateTimePrototype.cpp` already has a source comment acknowledging it. - The buddhist calendar's `year` returns the ISO year instead of BE, because `TemporalCore::calendarYear()` uses ICU's `UCAL_EXTENDED_YEAR`, which is the Gregorian year for the `GregorianCalendar`-derived calendars. The same function already special-cases `roc` for this exact quirk. - Chinese/dangi leap-month placement disagrees with the reference on 2-3% of dates, and the `ad`/`bc` era aliases are not accepted (`ce`/`bce` are). - Legacy IANA time zone IDs such as `CET` and `EST5EDT` are rejected. This is not Temporal-specific: `new Date()` and `Intl.DateTimeFormat().resolvedOptions().timeZone` already fall back to `UTC` for them today. The first two are being filed upstream on bugs.webkit.org with one-line reproductions. None of these are regressions this PR can introduce; they are pre-existing in the JSC implementation, which is only reachable behind `BUN_JSC_useTemporal=1` today. ### Nothing else needed to change - `test/js/node/test/common/globals.js` already handles the new global conditionally (`if (global.Temporal) intrinsics.add('Temporal')`). - `test/js/bun/jsc/temporal-global.test.ts` (added by #34373 to pin the off-by-default state) is updated to assert the new default and the `BUN_JSC_useTemporal=0` opt-out; the subprocess flag tests live there, next to the other JSC option coverage, and the in-process functional coverage lives in `test/js/web/temporal/temporal.test.ts`. - `structuredClone` and `postMessage` correctly reject Temporal objects with a `DataCloneError`, matching Node. - Temporal string parsing uses its own strict ISO 8601 grammar in `ISO8601.cpp`. It never touches the date parser selected by `useV8DateParser`, which has exactly one call site (`DateCache::parseDate`), so there is no interaction with that override. ### LeakSanitizer The x64-asan lane flags JSC's Temporal time zone bridge on any test that touches a named time zone. `JSC::TemporalCore::withTimeZone` keeps a process-lifetime `LazyNeverDestroyed` LRU of at most 8 open `UCalendar`s (evicted entries are `ucal_close`d), and the `TimeZoneCacheEntry` that owns each one lives in bmalloc memory, which LeakSanitizer does not scan as a root region, so the libc-allocated `UCalendar` is misreported as a direct leak.

A fuzz variant that hammers the port while GC is in flight instead lands in the sweep window: 10/10 within 30s as a silent SIGABRT, `TypeError: r.text is not a function` on the fetch result, or another listener's `open` handler answering on the dropped listener's port. Under ASan the dispatch faults in `Bun__SocketHandlers__getField` (`JSSocketHandlers.cpp`) or as a UBSan member call on null ClassInfo in `Bun__JSValue__call`, reached from `NewSocket::on_open` via `us_internal_dispatch_ready_poll`, i.e. a loop dispatch on the swept handlers cell before the finalizer ever runs. ## Cause `Listener::unref` released the event-loop ref and then downgraded `this_value` to weak whenever `active_connections == 0`, while the listen socket was still open. That contradicts the field's own contract ("Strong while it is listening or has connections"): the wrapper's `handlers` slot is the only GC root of the `JSSocketHandlers` cell that every accept dispatches into. With the wrapper weak and the JS reference dropped, GC collects both while the socket keeps accepting, so `on_open` for the next connection reads a swept cell; after the finalizer runs, the port is closed outright, which is not Node semantics either (libuv keeps unref'd servers accepting). ## Fix `unref()` now only does `poll_ref.unref()`. The idle downgrade already lives in the two places that are gated on the listen socket being closed: `do_stop` (close with no connections) and `Handlers::mark_inactive` (last connection drains after a close). A stopped or idle listener is still collected exactly as before; a listening one stays reachable until `stop()`, and the process can still exit because the event-loop ref is released. This is a different site from #36181, which defers the finalizer's socket-group close out of the GC sweep when a collected listener still has live connections: that covers the teardown dispatch during finalization, while this bug fires on a fresh accept before any finalizer runs and needs no connections at drop time. Both changes stand on their own. ## Verification New test in `test/js/bun/net/socket.test.ts` spawns a child that drops four unref'd listeners, drives GC with allocation churn, and fetches every port each round; the child must serve every request and then exit on its own (proving `unref()` still releases the loop). `USE_SYSTEM_BUN=1`: child gets `ConnectionRefused` on the first collected listener, test fails (also fails on an unfixed debug build, 1.5s). `bun bd test`: passes (4.1s, ASan). The 30s fuzz hammer on the fixed debug build: 18 rounds, 80/80 requests served, no crash, no wrapper collected while listening. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

Observed failure modes (stress repro below, debug and ASAN builds): - `ASSERTION FAILED: isMarked(cell)` in `JSC::Heap::addToRememberedSet` (Heap.cpp:1268) - segfaults in `JSC::Integrity::auditCellFully` / `JSC::cellSize` under `Bun__JSValue__call` - JS-visible type confusion: `TypeError: this.emit is not a function ... at #onChange (internal:fs/watchfile:14)` ### Cause `StatWatcher::close()` (the `unwatchFile()` path) sets `closed` and downgrades `this_value` from Strong to `JsRef::Weak`. `JsRef::Weak` is a raw `JSValue` with no GC registration, so `try_get()` on it cannot check liveness. The wrapper, its cached listener (the bound `#onChange`), and its cached `prevStat` are then only reachable through that dead-or-dying wrapper. Both initial-stat main-thread callbacks bail on `closed` before touching the wrapper, but `swap_and_call_listener_on_main_thread` did not: a task queued by the stat thread just before `unwatchFile()` would read the cached `prevStat`, write-barrier the new Stats into the wrapper, and call the cached listener, all on a cell GC may have collected. ### Fix Bail on `closed` in `swap_and_call_listener_on_main_thread` before reading `this_value`, matching the existing checks in `initial_stat_success_on_main_thread` / `initial_stat_error_on_main_thread`. `close()` always runs on the JS thread before the wrapper can die (the Strong self-ref keeps it alive until then), so `closed == false` implies the wrapper is still strongly referenced. This also restores the Node.js guarantee that no callback is delivered after `unwatchFile()` returns. ### Test `unwatchFile()` removes all `"change"` listeners before stopping, so a listener re-attached to the returned `StatWatcher` right after `unwatchFile()` returns must never fire. On the unfixed build the already-queued native task still calls the cached bound `#onChange`, which emits into the re-attached listener. The test lines up the stat-thread poll with the closing turn (no GC required, no crash roulette): - unfixed debug build: 12/12 rounds observe a late callback, test fails - fixed build: 0 late callbacks across repeated runs (probe: race state still reached 50/50 rounds, all bailed) - stress repro below: assertion failure within ~8s on the unfixed debug build; 8x20s runs clean on the fixed build

Node v26.3.0 prints `no crash`. ## Cause `send_data`'s padded single-frame branch (and the two padded branches in `Stream::flush_queue`) built the payload inside `SHARED_REQUEST_BUFFER.with_borrow_mut(|buffer| { ...; writer.write_all(&buffer[..payload_size]) })`, so the `write_all` ran inside the borrow. When the frame crosses the cork boundary, `write()` -> `flush_cork_buffer()` -> `_write()` -> `onWrite` runs the Duplex `_write` (user JS) with the thread-local still mutably borrowed; the nested `req2.write()` -> `send_data` borrows it again and panics. Native TCP/TLS transports never run JS from `_write`, so only JS-backed transports are affected. The rest of the write path already follows the rule that no thread-local borrow is held across `_write` (`uncork`, `flush_batch_buffer`, `flush_cork_buffer` move their Vec out first); these three sites predate it. ## Fix Add `DirectWriterStruct::write_padded(data, padding)` and use it at all three sites. The scratch stays shared and reusable, but it now lives in the VM's `RareData` (per review: a thread-local static is wrong with worker_threads; per-VM is the right scope). `write_padded` takes the buffer out of its `rare_data` slot by value for the duration of the write, so nothing is borrowed across `write()`: a re-entrant padded write finds the slot empty, allocates its own buffer, and the slot keeps one buffer for reuse when they return. `SHARED_REQUEST_BUFFER` is removed, along with the three `unsafe { ptr::copy }` blocks. Frame ordering on the wire when a JS transport re-enters the session mid-frame is unchanged by this PR (it behaves like the unpadded path does today, see #36918 for that); this only removes the abort and keeps each frame's own bytes intact. ## Verification New test in `test/js/node/http2/node-http2.test.js`: three padded DATA writes in one tick over a JS Duplex (a corked fill frame, an outer frame that crosses the cork boundary, and a side-stream write issued from inside the transport's `_write` during that flush), then counts the payload bytes that reach the transport. Expected `{ reentered: true, total: 28795, A: 12000, B: 3000, C: 13000 }`, which is also what node v26.3.0 produces for the same script. - before (release and debug+ASAN): subprocess aborts with `panic: RefCell already borrowed`, test fails - after: passes; full `node-http2.test.js`: 311 pass, 6 skip, 0 fail Related: #36905 (merged) and #36910 cover the borrowed-payload side of the same re-entrant Duplex write path; this one is independent of both (the padded path already copied its payload, the problem was the held borrow). --- **[review]** gate passed · iteration 0 · 3 files touched

A busy loop of failing pipelines retained every context: Bun.gc(true) could not reclaim them and RSS grew ~280 KiB per iteration until the process went idle. A server gzipping response bodies whose upstreams abort holds hundreds of MB of dead deflate contexts under sustained load, with nothing visible in heapUsed. Repro loop (what the test runs in a child process): ```js let n = 0; const src = new ReadableStream({ pull(c) { if (++n > 5) throw new Error("source failed"); c.enqueue(new Uint8Array(8192).fill(n)); }, }); try { await new Response(src.pipeThrough(new CompressionStream("gzip"))).arrayBuffer(); } catch {} ``` Measured RSS growth over 448 errored pipelines (after full GC): - bun 1.3.14 (node:zlib-backed implementation): 132 MiB; at 3000 iterations RSS reaches ~874 MB and survives Bun.gc(true) - after #36695: 7 MiB release, 8 MiB debug+ASAN #36695 frees the coder at ClearAlgorithms, the shared terminal for post-flush, error, and cancel, leaving the finalizer as a fallback for abandoned streams. Nothing pinned that behavior; this test does, with a 64 MiB bound. ## Verification - Fails on bun 1.3.14: expect(deltaMiB).toBeLessThan(64) receives 132 - Passes on current main: bun bd test test/js/web/streams/compression.test.ts, 36 pass - The child disables the ASAN allocator quarantine (quarantine_size_mb=0, same approach as the shell and archive leak tests) so the delta measures retention rather than quarantined frees --- **[stamp-90s]** gate passed · iteration 1 · 1 files touched

If the child outlives the parent, the port stays in LISTENING state (attributed to the dead parent's PID) even after `server.close()` completes and the parent exits normally: ```text LocalAddress LocalPort State OwningProcess ------------ --------- ----- ------------- 127.0.0.1 43123 Listen 23068 <- dead parent PID ``` ### Cause uSockets creates sockets with plain `socket()`. On Windows that returns an inheritable handle (the `SOCK_CLOEXEC` branch in `bsd_create_socket` is POSIX-only). When `node:child_process.spawn` creates the child via CreateProcess with `bInheritHandles=TRUE` (needed for stdio), every live socket handle is duplicated into the child, so the kernel keeps listen sockets open for as long as the child lives. `accept()` likewise returns inheritable handles. ### Fix In `packages/bun-usockets/src/bsd.c`, matching what libuv does: - `bsd_create_socket`: on Windows, create sockets with `WSASocketW(..., WSA_FLAG_OVERLAPPED | WSA_FLAG_NO_HANDLE_INHERIT)` instead of `socket()`. - `bsd_accept_socket`: clear `HANDLE_FLAG_INHERIT` on accepted sockets via `SetHandleInformation`. All TCP, UDP, and connect sockets funnel through `bsd_create_socket`, so this covers `Bun.serve`, `node:http`, `node:net`, and dgram. ### Verification (on Windows) The new test (`test/js/node/child_process/child-process-socket-inherit.test.ts`) spawns a parent that listens on port 0, spawns a detached child, closes the server, and exits; the test then asserts connecting to the port yields ECONNREFUSED while the detached child is still alive. - Unfixed canary (`USE_SYSTEM_BUN=1`): fails, the connection succeeds because the inherited listen socket still accepts. - With this fix (`bun bd test`): passes, and the issue's original repro now matches Node: parent exited, child alive, `Get-NetTCPConnection -LocalPort 43123 -State Listen` returns nothing. - Sanity: `test/js/bun/net/tcp-server.test.ts`, `test/js/node/net/node-net.test.ts`, `test/js/bun/udp/udp_socket.test.ts` all pass on Windows with the fix (272 pass, 0 fail).

Same abort for an `editor` `toString`, a `line` `toString`, or a `column` getter. Deterministic on 1.4.0-canary; nothing needs to be spawned. ### Cause The whole option-parsing body runs inside `EDITOR_CONTEXT.with(|cell| cell.borrow_mut())`. While that thread-local `RefCell` is mutably borrowed, `opts.get_truthy(global, "editor")` / `"line"` / `"column"` and the `to_slice` coercions call user JS. A re-entrant `Bun.openInEditor` call from any of those hooks hits `borrow_mut()` again and panics. ### Fix Read and coerce `editor`, `line`, and `column` to strings before taking the `EDITOR_CONTEXT` borrow. Only the slot update (`detect_editor`, name caching) and `editor.open()` remain inside it, and neither can call back into JS, so the borrow can no longer be held across user code. Minor observable change: options are now read upfront, so when the named editor cannot be found, the `line`/`column` getters run before the error is thrown instead of being skipped. ### Verification New test in `test/js/bun/util/open-in-editor-gc.test.ts` spawns a child that exercises all four re-entrant variants (editor getter, editor toString, line toString, column getter) with an empty `PATH` so no real editor is ever detected or spawned. Without the fix the child aborts with the panic above (exit 134); with it the child prints all four markers and exits 0. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

When the session's transport is user JS, that JS runs synchronously at several points before the send has consumed the slice, and can `transfer()` or `resize(0)` the buffer underneath it: | where JS runs mid-send | what goes stale | measured on main | |---|---|---| | the cork flush when a single DATA frame (≤16374 B) straddles the 16 KiB cork behind corked HEADERS | `bytes[avail..]` in `write()`'s loop | 11280/16374 foreign (the repro above); `resize(0)` SEGV | | the flush of the 9-byte DATA frame *header* when the cork is within 8 bytes of full | the whole payload, read by the next `write()` | 8000/8000 foreign | | `flush_batch_buffer()` right before the flow-control-limited tail is queued | the slice `queue_frame` copies | 32768/98303 foreign | | `cork()`: taking the cork slot flushes *another* session's corked bytes through that session's transport | the whole payload | 8000/8000 foreign (two Duplex sessions) | | any of the above with a `TLSSocket` over a JS Duplex (every TLS record is written through the Duplex) | same | 11283/16374 and 32768/98303 foreign, received by a real `createSecureServer` | The multi-frame path already copies into the owned batch buffer for non-TCP sockets, which is why larger single writes previously measured safe. Native TCP/TLS sockets over real connections never run JS from a write and are unaffected. ## Fix Decide once at the `writeStream` boundary, mirroring the defensive copy the inbound `read()` path already makes: `stable_payload()` copies the payload into an owned buffer for the duration of `send_data` when this session's transport write runs JS (`BunSocket::None`, or a socket whose `InternalSocket` is `UpgradedDuplex`), or when the cork slot is currently held, with pending bytes, by a session whose transport does. Otherwise it stays borrowed, so native sockets keep the zero-copy path. A copy inside `write()` (the first revision of this PR) cannot cover this: the slice goes stale *between* two `write()` calls of one send, and before `queue_frame`. `goaway`'s `opaqueData` was already given an owned copy at its boundary in #36905. ## Verification `test/js/node/http2/node-http2.test.js` gains a `describe.concurrent` block with one subprocess case per row above (wire-content oracle; for the TLS cases the oracle is the body the server receives). All 7 fail on main (5 with foreign bytes on the wire, `resize0` by crashing) and pass with this change; the rest of the file (317 tests) and the neighbouring http2 test files pass. --- **[review]** gate passed · iteration 0 · 2 files touched

For a native `ByteStream` request body (an upstream response body piped into `fetch()`), `wire_native_sink` installs the sink's `source` handle *before* any of its `EndedInline` returns (`ReadableStream.rs:328` vs `:337/:352/:359`), so a stream that picked up an error or its last chunk between `fetch()` and the `can_stream` tick comes back `EndedInline` with a native source attached. The `EndedInline` arm released the `+1` (via `write_end_request`) but left `self.sink` installed with `ended == false`. Every terminal path then runs `cancel_request_body_sink`, which saw a "live" native sink and took its native arm: `abort_task()` plus a second `write_end_request` — releasing the same `+1` again. The double release collapses the refcount while the other owners (the JS-side initial ref and the HTTP thread's in-flight ref) still use the tasklet. Under ASAN the deterministic form is the trace below (deinit runs inside `cancel_request_body_sink`, then `on_progress_update` keeps using `self`). In release builds the same imbalance frees the tasklet while it is still in use (or double-frees, handing a live tasklet's block back to the allocator), which surfaces as downstream crashes in the fetch completion path — the BUN-3BZF unwrap is the tasklet's `http` field read from freed/recycled memory. ``` READ of size 8 ... core::mem::replace:: #2 FetchTasklet::on_progress_update FetchTasklet.rs:1158 freed by thread T0 here: #12 FetchTasklet::deinit FetchTasklet.rs:509 #16 FetchTasklet::write_end_request FetchTasklet.rs:2281 #17 FetchTasklet::cancel_request_body_sink FetchTasklet.rs:2368 #18 FetchTasklet::on_progress_update FetchTasklet.rs:1143 ``` ### Fix Leave the sink in the same state `end_from_stream` (the normal native termination) leaves it: `ended = true`, source and task detached. The terminal `cancel_request_body_sink` then hits its existing `if sink.ended { return }` guard and cannot release the ref a second time (it also no longer spuriously aborts a request whose body simply ended inline). ### Verification - New fixture `fetch-stream-body-ended-inline-fixture.ts` drives the window: an upstream server that advertises a larger `content-length` than it sends and closes a few ms later, piped as the body of a TLS `fetch()` (the handshake keeps the wire-attempt window open), 100 iterations. - Unfixed debug+ASAN build: heap-use-after-free with the trace above, 8/8 runs. - Fixed build: `bun bd test test/js/web/fetch/fetch-abort-stream-body.test.ts` passes (5 pass, 1 pre-existing skip), including the new test. - `test/js/web/fetch/body-stream.test.ts`: 9086 pass / 0 fail. `fetch.test.ts` and `fetch.stream.test.ts`: identical pass/fail counts to an unfixed baseline in the same container (the failures are pre-existing network/timeout issues). - The test is `skipIf(!isASAN)`: the release build corrupts silently, so only sanitizer lanes can observe the failure. --- src/runtime/webcore/fetch/FetchTasklet.rs | 10 +++ .../web/fetch/fetch-abort-stream-body.test.ts | 24 +++++++ .../fetch-stream-body-ended-inline-fixture.ts | 65 +++++++++++++++++++ 3 files changed, 99 insertions(+) create mode 100644 test/js/web/fetch/fetch-stream-body-ended-inline-fixture.ts diff --git a/src/runtime/webcore/fetch/FetchTasklet.rs b/src/runtime/webcore/fetch/FetchTasklet.rs index cf459db6e901..f477af732475 100644 --- a/src/runtime/webcore/fetch/FetchTasklet.rs +++ b/src/runtime/webcore/fetch/FetchTasklet.rs @@ -668,6 +668,16 @@ impl FetchTasklet { }) { crate::webcore::readable_stream::NativeWireResult::Wired => return, crate::webcore::readable_stream::NativeWireResult::EndedInline(err) => { + // The source finished inside the wire attempt, so leave the + // sink in the state `end_from_stream` leaves it: ended, with + // the source and task detached. `write_end_request` below is + // the single balancing release of the `+1` taken above; a + // sink left `ended == false` here would make the terminal + // `cancel_request_body_sink` treat it as a live native sink + // and release that ref a second time, freeing the tasklet + // while it is still in use. + sink.ended = true; + sink.source.clear(); sink.task = None; let err_js = err.map(|err| { let err_js = err.to_js(&global_this); diff --git a/test/js/web/fetch/fetch-abort-stream-body.test.ts b/test/js/web/fetch/fetch-abort-stream-body.test.ts index 02727f786234..15bee4e1c8bd 100644 --- a/test/js/web/fetch/fetch-abort-stream-body.test.ts +++ b/test/js/web/fetch/fetch-abort-stream-body.test.ts @@ -55,6 +55,30 @@ test expect(exitCode).toBe(0); }); +// A native ByteStream request body (an upstream response body piped into +// fetch) that errors or finishes between fetch() and the can_stream tick is +// ended inline by wire_native_sink.

Fixes a use-after-free in the HTTP/2 (and HTTP/3) fetch client when a server completes a response at header time without closing the stream. **Problem** `deliver_stream` follows a detach-before-terminal discipline: a terminal progress update (`has_more == false`) frees the `ThreadlocalAsyncHTTP` that embeds the `HTTPClient`, so every path that can dispatch one first clears `stream.client` / `client.h2` and removes the stream. The header-progress call missed one case: a response whose headers carry `Content-Length: 0` but still announce a body, e.g. a `text/event-stream` content-type (`handle_response_metadata` returns `ContinueStreaming` for SSE regardless of content length). `state.is_done()` is then already true at header time (`total_body_received >= content_length`, 0 >= 0), so the `headerProgress` update at `h2_client/ClientSession.rs:1061` dispatched a terminal result and freed the client while the stream was still attached to the session. The very next statement reads the freed `client.state`, and any later frame for that stream id (DATA, RST_STREAM, connection close) re-enters the freed client and can dispatch a second terminal result into the freed tasklet. On a debug build the first terminal dispatch trips the teardown assertion deterministically: ``` panic: assertion failed: client.h2.is_none() ::on_async_http_callback_raw src/http/AsyncHTTP.rs:754 ::send_progress_update_multiplexed src/http/lib.rs:4292 ::deliver_stream src/http/h2_client/ClientSession.rs:1061 ``` The HTTP/3 client session has the same hole at the same point in its `deliver` (`h3_client/ClientSession.rs`). Reachability: fetch only uses HTTP/2/3 when opted in (`protocol: "http2"`, the CLI flag, or the experimental env flags), so this does not affect default-configuration fetch. **Fix** Fold `client.state.is_done()` into the existing headers-complete-the-response branch in both sessions. The zero-length case now detaches the stream and finishes through `finish_stream` exactly like HEAD/204/304 and END_STREAM-at-headers already do: the response delivers complete with an empty body (same outcome as the HTTP/1.1 path for the identical response, where the terminal progress update also fires at header time), the Content-Length check in `finish_stream` still enforces RFC 9113 section 8.1.1 if stray DATA arrived in the same read, and the deliver loop RST_STREAMs the still-open stream so the server releases its slot. With the branch handling `is_done()`, the header-progress update below it can no longer be terminal (`state.fail` is only ever set by paths that dispatch and detach immediately). In the HTTP/3 session the fold also routes a degenerate zero-length redirect (3xx + `Content-Length: 0` + SSE content-type) through the branch's existing detach-then-redirect handling instead of redirecting while the stream is attached. ### How did you verify your code works? New test in `test/js/web/fetch/fetch-http2-adversarial.test.ts`: a raw h2 server answers with HEADERS (`END_HEADERS` only, no `END_STREAM`) carrying `content-length: 0` and `content-type: text/event-stream`. Before the fix the child process aborts with the assertion above; after, fetch resolves with a complete empty 200 response and the child exits cleanly. Also ran `fetch-http2-adversarial` (16 pass), `fetch-http2-client` (62 pass), `fetch-http2-leak` (7 pass), `fetch-http3-client` (53 pass), `fetch-http3-adversarial` (27 pass), and the undici-h2 / wpt-h2 suites against the debug+ASAN build. --- src/http/h2_client/ClientSession.rs | 4 ++ src/http/h3_client/ClientSession.rs | 8 +++- .../web/fetch/fetch-http2-adversarial.test.ts | 45 +++++++++++++++++++ 3 files changed, 56 insertions(+), 1 deletion(-) diff --git a/src/http/h2_client/ClientSession.rs b/src/http/h2_client/ClientSession.rs index 1006086664d4..2fe7b1c34c31 100644 --- a/src/http/h2_client/ClientSession.rs +++ b/src/http/h2_client/ClientSession.rs @@ -1038,8 +1038,12 @@ impl ClientSession { // Deep-copy before detaching: `response` borrows // `stream.decoded_headers`. client.h2_clone_metadata(&response); + // `is_done()`: Content-Length: 0 can arrive as `HasBody` (e.g. an + // SSE content-type), which would make the headerProgress update + // below terminal and free `client` while the stream still holds it. if result == HeaderResult::Finished || (stream.remote_closed() && stream.body_buffer.is_empty()) + || client.state.is_done() { stream.client = None; client.h2 = None; diff --git a/src/http/h3_client/ClientSession.rs b/src/http/h3_client/ClientSession.rs index 643bd40c0d13..ac67ec9081f9 100644 --- a/src/http/h3_client/ClientSession.rs +++ b/src/http/h3_client/ClientSession.rs @@ -307,7 +307,13 @@ impl ClientSession { Ok(r) => r, Err(e) => return self.fail(stream, e), }; - if result == HeaderResult::Finished || (done && st.body_buffer.is_empty()) { + // `is_done()`: Content-Length: 0 can arrive as `HasBody` (e.g. an + // SSE content-type), which would make the headerProgress update + // below terminal and free `client` while the stream still holds it. + if result == HeaderResult::Finished + || (done && st.body_buffer.is_empty()) + || client.state.is_done() + { if client.state.flags.is_redirect_pending { self.detach(stream); // SAFETY: re-derive — detach() invalidated the prior Unique tag. diff --git a/test/js/web/fetch/fetch-http2-adversarial.test.ts b/test/js/web/fetch/fetch-http2-adversarial.test.ts index 16932ec21046..15d34d3ddf69 100644 --- a/test/js/web/fetch/fetch-http2-adversarial.test.ts +++ b/test/js/web/fetch/fetch-http2-adversarial.test.ts @@ -326,6 +326,51 @@ describe.concurrent("fetch() HTTP/2 adversarial", () => { ); }); + // 9.

On a keep-alive connection the stray terminator is parsed as the start of the next response, so a later request on the same socket fails with `Malformed_HTTP_Response`. Reproduces on 1.2.21 through current canary. ### Cause In `HTTPServerWritable` (src/runtime/webcore/streams.rs), `end()` with bytes still buffered defers the final send to the auto-flusher. `on_auto_flush()` then drains through `send_readable_without_auto_flusher()`, which takes the `requested_end` branch and calls uWS `res.end(...)`. That writes the remaining data plus the terminating `0\r\n\r\n` chunk and `markDone()`s the response. `on_auto_flush()` records this (`ended_response = true`) and calls `finalize()`, but `finalize()` only checked `!self.done` and called `res.end_stream(false)`, which writes a second terminating chunk (uWS `sendTerminatingChunk` emits it unconditionally once the response is in chunked mode). `end_from_js()` avoids this by calling `mark_done()` before `finalize()`; the auto-flush and `on_writable` drain paths do not, so any end that finishes through them double-terminated. `flush(true)` before `close()` empties the buffer, which is why the workaround in the issue avoids the bug. ### Fix `finalize()` now skips `end_stream()` when the sink already fully ended the response (`ended_response`), which every drain path sets before calling `finalize()`. The flag-based guard also avoids touching the uWS response state on HTTP/1, where the response may already be recycled after `markDone()`. ### Test Added to `test/js/bun/http/serve-direct-readable-stream.test.ts`: over a raw keep-alive TCP socket, request the direct-stream response, then a plain Content-Length response on the same connection with `Connection: close`, read to EOF, and assert exactly one `0\r\n\r\n` appears and that the bytes after it are the next response's status line. Fails on the unfixed build (two terminators), passes with the fix; the rest of the file still passes. --- **[review]** gate passed · iteration 0 · 2 files touched

After: `type1:len11272,type0:len16374,type6:len8`, body intact (matches node). ### Cause With no native socket, the session's bytes reach the wire through the `onWrite` handler, which calls `socket.write()` and so runs the transport's `_write` synchronously. `H2FrameParser::write` filled the 16 KiB cork to the record boundary with the first `avail` bytes of the DATA payload, flushed the cork through that handler, and corked the payload's remainder afterwards. A frame serialized from inside `_write` found the cork empty and was appended first, ahead of the remainder. Two more faces of the same re-entrancy surfaced while testing: - `flush()`'s JS-transport arm handed `write_buffer` to `onWrite` and only cleared it after the call returned. When that call re-entered `flush()` (`session.settings()` calls it directly; an auto-flush can be drained together with the call's microtasks), the nested flush sent the same bytes again, putting a second connection preface + SETTINGS in the middle of the stream. - Review (thanks to the header-block finding) showed the per-frame boundary was not enough: a frame issued while a header block larger than one frame was in flight landed between `HEADERS(!END_HEADERS)` and its `CONTINUATION`, which RFC 9113 4.3 makes a connection-fatal PROTOCOL_ERROR for the peer. ### Fix For sessions without a native socket, `write()` routes through a `TxFrameTracker` that follows the outbound byte stream (frame headers, payload lengths, END_HEADERS across HEADERS/PUSH_PROMISE/CONTINUATION) and only hands bytes to `onWrite` where another frame may legally follow: at a frame boundary, outside a header block. A unit that overflows the cork is assembled in `tx_spill` (corked prefix + its chunks) and written whole once its last chunk arrives, which always happens synchronously, so a frame issued re-entrantly corks up behind it instead of landing inside it. `flush()` refuses to run mid-unit; its JS-transport arm takes `write_buffer` out before calling `onWrite` (no double-send on re-entry) and skips the prefix a native socket already wrote before detaching (`write_buffer_offset`). Since bytes are now copied into the cork or spill before any JS runs, this also closes the window where the payload slice borrowed from a user `ArrayBuffer` was read again after `_write` re-entered JS (detach/resize during the flush sent freed or foreign heap bytes as the DATA payload; verified with a transfer/respray oracle). The native TCP/TLS path (no JS re-entry) keeps its fill-to-record-boundary behavior unchanged. ### Verification `test/js/node/http2/node-http2.test.js` gains `frames issued from inside a user-supplied Duplex transport's _write`: a matrix of nested `ping()` / `settings()` / `goaway()` / `request()` / multi-frame `data` issued from the transport's `_write`, crossed with the outer write being a single-frame DATA or a HEADERS+CONTINUATION header block, and with the transport reporting backpressure. Each case captures the raw bytes and asserts every byte belongs to exactly one complete frame, header blocks are contiguous, the DATA frame carries exactly the body, nothing is duplicated, and the nested frames follow the unit they were issued from. 15/15 fail on current canary (the 5 continuation cases also failed against the earlier per-frame version of this fix), 15/15 pass with this change. Also run with the debug build: `node-http2.test.js` (331 tests), `h2-conformance.test.ts` and the other `test/js/node/http2/*` files, all 254 `test/js/node/test/parallel/test-http2-*` and the 5 sequential http2 tests, `rust:check-all`. --- **[review]** gate passed · iteration 2 · 2 files touched

Method: started from `scripts/find-dead-exports.ts`, narrowed 8,259 candidates to 1,039 whose name appears in exactly one file across src/, scripts/, test/, and regenerated `build/debug/codegen/` output, then demoted each to private and let the workspace's `dead_code = deny` prove which were genuinely unreferenced. Items the compiler proved live (macro expansions, return-position escapes, cfg(windows)/cfg(darwin) usage, codegen references) were restored; the rest were deleted. Areas with open dead-code PRs (#36237, #35775, #36115, #35437, #35880) were excluded, and the one overlapping deletion found during final diffing (`kGetNativeReadableProto`, already in #35775) was dropped from this PR. ### Removed **FFI declaration crates** (unused imports of vendored C functions; declarations only, no link-time effect): - `src/mimalloc_sys/mimalloc.rs`: ~100 declarations (heap-local variants `mi_heap_*`, stats/options surface `mi_stats_*` `mi_option_*`, posix shims `mi_posix_memalign`/`mi_valloc`/`mi_pvalloc`, C++ `mi_new_*` family) - `src/windows_sys/externs.rs`: never-constructed `WinsockError` + ~100 `WSA*` error consts, `GetBinaryTypeW`, `CreateJobObjectW`, `M128A` kept (used by `CONTEXT` on windows) - `src/zlib_sys/win32.rs`: 44 declarations (`gz*` file API, `deflateTune`, `inflateUndermine`, `zlibCompileFlags`, ...) - `src/cares_sys/c_ares.rs`: 21 (option/server-config surface `ares_set_servers*`, `ares_mkquery`, `ares_parse_txt_reply_ext`, ...) - `src/lsquic_sys/lib.rs`: 11 (handshake/conn status consts, stream-ctx helpers) - `src/brotli_sys`, `src/boringssl_sys`, `src/libdeflate_sys`: 17 combined (`BrotliEncoder*` estimators, `TLS_with_buffers_method`, `libdeflate_*_decompress`, ...) **Rust runtime/support crates**: - `src/bun_core/env.rs`: `BuildTarget::Wasi` variant + `IS_WASI` (never constructed; `IS_BROWSER` simplifies to `IS_WASM`) - `src/jsc/HTTPServerAgent.rs`: 5 unused Rust-side imports of `Bun__HTTPServerAgent__notify*` + 2 type aliases - `src/runtime/test_runner/mod.rs`: `JSGlobalObjectTestExt::throw2` (duplicated `throw_error`) - `src/runtime/server/NodeHTTPResponse.rs`: unused `pause_socket` sibling cleanup; `pause_socket_reads` kept (referenced by generated bindings) - ~230 surviving demotions of file-local `pub` items to private across 60 crates, which moves them permanently under `dead_code` analysis - assorted single items: dead re-export lines in `sql_jsc`/`sourcemap_jsc`/`bundler_jsc`/`runtime/api.rs`, `EventLoopGuard`-adjacent aliases, unused imports **Built-in JS / codegen / build scripts**: - `src/node-fallbacks/timers.promises.js` (238 lines): never registered in `src/resolver/node_fallbacks.rs`'s 23-module registry, so it was built and compressed on every build but could never be served - `src/js/internal/crypto/x509.ts` + its row in `ProcessBindingNatives.cpp`: `process.binding("crypto/x509")` is implemented natively in `BunProcess.cpp` - `src/js/internal/validators.ts`: `validateUndefined`, `validateSignalName`/`validatePlainFunction` export entries - `src/js/internal/{shared,tls,streams/utils}.ts`: dead export-object entries (definitions stay where used in-file); `primordials.js`: 5 dead scalar-constructor keys (typed-array keys kept: `util.inspect` reaches them via computed `primordials[tag]` access) - `src/codegen`: `camelCase`, `pascalCase`, `warnOnIdentifiersNotPresentAtRuntime`, `DOMJITReturnType`, `ownRow`, `cppPointer` - `scripts/build`: `explainFlags` (no `--explain-flags` exists), `assertDefined`, `depSourceStamp`; root `package.json` `bump` script (its target was deleted in #13427) **Orphaned files**: `src/fixtures_example.com.html`, `src/zlib.test.txt` + `src/zlib.test.gz` (2021 inline-test fixtures), `src/fallback.html` (only `fallback-backend.html` is embedded), `src/logo.svg`, `src/favicon.png` **Stale commented-out C++ blocks** (~243 lines, all >6 months old via git blame): minicoro scaffolding in `coroutine.cpp` (2022), pasted Node JS source in `JSX509CertificatePrototype.cpp`, commented `BINDING_INTEGRITY` vtable checks, `InspectorInstrumentation` calls in `WebSocket.cpp`, suspended-event-loop paths in `JSDOMPromiseDeferred.cpp`, commented-out function bodies in `Performance.cpp`/`Event.cpp`/`DOMWrapperWorld.cpp`/`ErrorEvent.cpp` and 8 more webcore files ### Verification ``` cargo check --workspace # green (dead_code/unreachable_pub/unused_* all deny) bun run rust:check-all # 10/10 targets (linux/macos/windows/freebsd/android x arches) bun bd # full debug build with freshly regenerated codegen bun test test/internal/source-lints/ # 65 pass (includes the new pin test below) bun bd test test/js/node/fs/fs.test.ts # 445 pass bun bd test test/js/node/http/node-http.test.ts # 144 pass, 1 env-dependent proxy failure also fails on released bun bun bd test test/js/bun/glob/match.test.ts # 29 pass bun bd test test/js/bun/resolve/resolve.test.ts # 50 pass ``` `test/internal/source-lints/dead-symbols-pub-exports-sweep.test.ts` pins representative removed symbols and the deleted files against reintroduction. The compiler-driven loop caught and restored every false positive the textual scan missed: methods on types that escape only via return position (`StdinReader::take_byte`, `HeaderSet::pairs`, bitset iterators), macro-referenced items (`comptime_string_map!` statics, `$crate::` paths), platform-gated items (`EmptyCopyFileState` on darwin/freebsd, `M128A`/`WriteKind` on windows), and generated-binding references (`get_insecure_http_parser`, `pause_socket_reads`) which only appear after codegen reruns. ### Followups (not removed) - `patches/ncrypto.patch` (919 lines) is referenced by nothing in `scripts/build/deps/*.ts` while every other patch file is; `src/jsc/bindings/ncrypto.{h,cpp}` already exist in patched form. Possibly kept as upstream-sync documentation, so left alone. - The `#if ENABLE(BINDING_INTEGRITY)` extern vtable scaffolding in `JSCustomEvent.cpp`/`JSPerformanceServerTiming.cpp` lost its only (commented) consumer but matches upstream WebKit codegen shape; left in place. - `.github/workflows/release.yml:2` references `.buildkite/scripts/release.sh`, which no longer exists (comment only). - `src/react_compiler` and `src/ini` were deliberately excluded: the former carries explicit not-yet-wired port markers, the latter's candidates proved live on inspection. --- **[decide:dep]** gate passed · iteration 3 · 126 files touched

The test kills the child in its `finally`, but on Windows `process.kill` only initiates `TerminateProcess`: the process object, including its working directory handle, is released asynchronously. `using dir` disposal runs `fs.rmSync` immediately after, so cleanup races the child's teardown and fails with EBUSY whenever the child has not finished dying. The socket assertions themselves pass (all 3 expect calls run); only cleanup fails. On the slower aarch64 runners the rm loses the race most of the time. It is worse on the failure paths: if the parent fixture exits non-zero, `childPid` is never parsed, the kill never runs, and the child holds the temp dir for the full 100 seconds. ### Fix Spawn the detached child with an explicit `cwd` outside the temp dir (`os.tmpdir()`). The child then never holds the directory that disposal removes, in every path, with no timing dependence. `cwd` is independent of handle inheritance (`lpCurrentDirectory` vs `bInheritHandles` in `CreateProcess`), so the code path exercised by the test is unchanged: the child is still spawned with inheritable-handle semantics while the listen socket is open. I considered retrying EBUSY in the harness `tempDir` disposal instead, but that would mask genuine process and handle leaks in every other Windows test. ### Verification (Windows 11 aarch64, the failing lane) - Unmodified test, release build with the #36938 fix (same setup as CI): EBUSY in 3 of 5 runs. - Fixed test, same build: 20 of 20 runs pass. - Fixed test, debug build with `packages/bun-usockets/src/bsd.c` reverted to its pre-#36938 state: fails with `Expected: "ECONNREFUSED", Received: "connected"`, so the test still detects the original inherited-socket bug (#36936). - Fixed test, debug build with current `bsd.c`: passes. The test is `skipIf(!isWindows)`, so Linux lanes are unaffected. --- .../node/child_process/child-process-socket-inherit.test.ts | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/test/js/node/child_process/child-process-socket-inherit.test.ts b/test/js/node/child_process/child-process-socket-inherit.test.ts index 2c05e012bc3a..ac3203bdb018 100644 --- a/test/js/node/child_process/child-process-socket-inherit.test.ts +++ b/test/js/node/child_process/child-process-socket-inherit.test.ts @@ -11,6 +11,7 @@ test.skipIf(!isWindows)("detached child does not inherit the parent's listening "parent.mjs": ` import { spawn } from "node:child_process"; import { createServer } from "node:http"; + import { tmpdir } from "node:os"; const server = createServer((_request, response) => response.end("ok")); await new Promise((resolve, reject) => { @@ -20,7 +21,11 @@ test.skipIf(!isWindows)("detached child does not inherit the parent's listening const port = server.address().port; // Spawn a detached child while the listen socket is open, then exit. + // cwd: the child outlives the test and would otherwise inherit this temp + // dir as its working directory, making tempDir cleanup fail with EBUSY on + // Windows while the killed child is still tearing down. const child = spawn(process.execPath, ["-e", "setTimeout(() => {}, 100000)"], { + cwd: tmpdir(), detached: true, stdio: "ignore", windowsHide: true, From 4c26d64a7a52df5d13d3ef38f8d46a1400a812cc Mon Sep 17 00:00:00 2001 From: robobun Date: Wed, 5 Aug 2026 12:28:03 -0700 Subject: [PATCH 129/304] bundler: make metafile import paths deterministic and match input keys (#34534) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Repro ```js // src/b/shared.js export const s = 1; // src/mid{0..29}.js (each: import { s } from "./b/shared.js"; export const m = s;) // src/entry.js (export * from each mid) ``` ```console $ bun build src/entry.js --outdir=o --metafile=m.json $ grep -o '"path": "[^"]*shared[^"]*"' m.json | sort | uniq -c 29 "path": "./b/shared.js" 1 "path": "/tmp/nd/src/b/shared.js" ``` Whichever `mid*.js` reaches the resolver first gets the absolute path; every other importer keeps the raw specifier. Which one wins varies with parse-task completion order, so two consecutive builds produce different metafiles. Neither form matches the string used as the key in `"inputs"` (`src/b/shared.js`), so `metafile.inputs[importPath]` never resolves and the `--metafile-md` reverse-dependency map misses most edges (it shows 1 importer of `shared.js` instead of 30). ## Cause `resolve_import_records` has a dedup path that, on a `path_to_source_index_map` hit, sets `record.source_index` and continues without rewriting `record.path`. The "first" importer falls through to the fresh-resolve branch and does get its path rewritten; every subsequent one keeps the original specifier. The metafile emitter then writes `record.path.text` unconditionally. ## Fix For bundled imports (`record.source_index` valid), emit `sources[source_index].path.pretty`, which is exactly the string used as the `"inputs"` key. Externals and chunk references (`source_index` invalid) keep `record.path.text`. After: ```console $ grep -o '"path": "[^"]*shared[^"]*"' m.json | sort | uniq -c 30 "path": "src/b/shared.js" ``` This matches esbuild's metafile format, is stable across runs, and lets the markdown report's reverse-dependency lookup hit the exact-match path for every edge. ## Tests Two new cases in `test/bundler/metafile.test.ts`: - 30 files import the same module; every import `path` must equal the `"inputs"` key and carry `"original": "./b/shared.js"`. - 5 consecutive builds of that graph produce identical import-path sets.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem The `server.stop(false)` drain promise resolved while keep-alive HTTP connections were still open and still serving. ```js // bun stopcensus.mjs [idle|inflight] import net from "node:net"; const mode = process.argv[2] || "idle"; const server = Bun.serve({ port: 0, hostname: "127.0.0.1", async fetch(req) { const p = new URL(req.url).pathname; if (p === "/slow") await Bun.sleep(600); return new Response("resp:" + p + ";"); } }); const c = net.connect(server.port, "127.0.0.1"); // ... one GET, then await server.stop(false), then a second GET on the same socket ``` `idle` → `stopResolvedAfterMs: 0, connFinAt: null, servedAfterResolve: 1`; `inflight` → resolves at response-finish (~450 ms), connection open, `/second` served. Deterministic on 1.4.0. Separately, `server.stop(true)` after an earlier `server.stop(false)` was a silent no-op: `stop_from_js` only entered `stop()` while `has_listener()`, and a prior graceful stop had already taken the listener. ## Cause `deinit_if_we_can` (and the `get_all_closed_promise` early-return, and the `stop_listening` unref gate) tested `pending_requests == 0 && !has_listener() && !has_active_web_sockets()`. Idle keep-alive HTTP connections are not in any of those terms; the predicate had no connection count, so it was satisfied while sockets were open and uWS kept routing requests on them. ## Fix - New `active_connection_count: Cell` on `NewServer`, fed by a uWS `filter` registered in `listen()` (fires `+1` on accept / post-TLS-handshake, `-1` from `HttpContext::onClose`). On WebSocket upgrade the socket is `us_socket_adopt`-ed out of the HTTP group and `HttpContext::onClose` never fires for it, so `note_websocket_opened` moves the count to the existing WebSocket tally. - The drain predicate, the `get_all_closed_promise` early-return and the `stop_listening` unref gate now include `!has_active_connections()`. The early-return also gains `!has_active_web_sockets()`: after an upgrade the connection count is 0, so on a websocket-only server this term is what keeps a repeat `stop()` call from returning a fresh resolved promise while the stored one is still pending. `stop(false)` does **not** close existing connections (per the review on the previous revision of this PR); the promise waits for them to close via `idleTimeout`, client disconnect, `server.closeIdleConnections()` or `server.stop(true)`. - `stop_from_js` / `dispose_from_js` enter `stop()` for an abrupt stop whenever the app has not yet been terminated, and `stop_listening` performs the `app.close()` teardown in that state, so `stop(true)` after `stop(false)` force-closes the surviving connections. ## Memory safety The deferred `js_value` downgrade is also a use-after-free fix. On `main`, once `pending_requests` hits 0 after a graceful `stop()`, `deinit_if_we_can` downgrades the wrapper to `Weak` while surviving keep-alive connections can still dispatch. The wrapper's slots are the only GC root of the configured handlers, and `JsRef::try_get()` returns the raw `JSValue` of a `Weak` ref with no liveness check, so after a GC pass a late request on such a connection calls swept cells: - release build: a freshly allocated object can reuse the swept handler cell and be invoked as the fetch handler. When the occupant is the fetch handler of another `Bun.serve` instance created after the stop, a request on the stopped server's surviving keep-alive connection is answered by that other instance's handler, crossing any in-process boundary between listeners (public vs admin, per-tenant servers). Other occupants surface as `error: Expected a Response object, but received '6'` (also `''` / `undefined`), response bodies resolving to unrelated objects, or a segfault - debug/ASAN build: UBSan `Structure.h: member call on null pointer of type 'JSC::ClassInfo'` in `Bun__JSValue__call`, reached from `NewServer::on_request` via `us_internal_dispatch_ready_poll` (a loop dispatch against the collected wrapper, not a finalizer-ordering problem) With the connection count in the predicate, the wrapper stays `Strong` until the last connection is gone, so a late dispatch always sees live cells. A standalone stress driver that creates fresh `Bun.serve` instances after every graceful stop confirms this: on unfixed builds it produces corrupted responses in release (about 1 per 120 stops over 72k rounds) and swept-cell sanitizer crashes under ASAN within 500 rounds, while this branch runs 1,000+ rounds under ASAN with zero reports. ## Verification New `server.stop() drain promise counts open connections` block in `test/js/bun/http/bun-server.test.ts`: - `idle keep-alive connection holds the promise until the client closes` / `in-flight request's connection holds the promise past response end`: fail-before `resolvedEarly: true, resolvedWhileOpen: true`; after `false, false` and the promise resolves once the client destroys the socket. - `stop(true) after stop(false) force-closes the surviving connection`: fail-before `closed: false`; after `closed: true`. New `request on a connection surviving graceful stop() never reaches a collected handler` stress test: parks pooled keep-alive connections across `stop()`, drops the server binding, churns the heap and forces GC, then sends late requests on the surviving connections. Rounds alternate between a plain `fetch` handler and a `routes:` param-route server, because the route dispatch reads the wrapper's `ServerRouteList` cell, a second collected-cell site (UBSan member call on null `TrailingArray<...ServerRouteList::IdentifierRange>` in `paramsObjectForRoute`, reached from `on_user_route_request`). Fails consistently on `main`: 6/6 with the release build (wrong bodies, responses from an already-collected server, segfaults) and 9/9 with the debug ASAN build across both shapes of the test, hitting both UBSan sites. Passes repeatedly with this PR (~35 s under ASAN, ~8 s release). The `late keep-alive WebSocket upgrade after stop()` test is updated: the wrapper downgrade is now deferred while the connection is open, so a pipelined upgrade on that connection reaches a live handler and `server.upgrade()` succeeds (previously it was refused because `handler.server` had been cleared). ``` bun bd test test/js/bun/http/bun-server.test.ts -t "drain promise counts open connections" # 3 pass USE_SYSTEM_BUN=1 bun test # 3 fail ``` `bun-server.test.ts`, `serve.test.ts`, `node-http.test.ts` and `websocket-server.test.ts` are unchanged apart from the usual environment-only failures that also fail on `main`. `node:http`'s `server.close()` calls `closeIdleConnections()` itself, so its observable behaviour is the same before and after. The `stop(true)`-after-`stop(false)` gate overlaps #33662 and #34961; this PR carries it because the connection-count term makes it the only way to force the promise through when a client keeps the socket open. --- **no test proof** · iteration 24 · Platform-specific test(s) that do not run on this machine.

Since it is an ancestor of every store entry, it sits on the upward module-resolution path of every package in the store: a package can `require()` a dependency it never declared and it still resolves, under Bun and Node alike. ``` mkdir proj && cd proj echo '{"dependencies":{"dep-a":"file:../dep-a.tgz","dep-b":"file:../dep-b.tgz"}}' > package.json # dep-b depends on dep-c; dep-a requires dep-c without declaring it bun install --linker=isolated bun -e 'require("dep-a")' # works: dep-c resolves via node_modules/.bun/node_modules/dep-c ``` Strictness is the point of the isolated layout, and this fallback makes phantom imports dependent on what else happens to be installed: the same import resolves in one project's closure and fails in another's. ### Fix Add `install.hoist = true | false` (bunfig.toml) and `hoist=false` (.npmrc), matching pnpm's `hoist` setting. It applies to the isolated linker only; hoisted installs ignore it, and the docs say so explicitly: - `hoist = false` skips creating `node_modules/.bun/node_modules` and nothing else. The project's declared-dependency symlinks, the store layout, bin links, and `publicHoistPattern` behavior are unchanged. Nothing in Bun's own resolution reads that directory; it is only created (lazily) for hoisted entries. - When a previous install left the directory behind, a `hoist = false` install removes it, so flipping the setting actually restores strictness without `rm -rf node_modules`. The removal unlinks the fallback symlinks without following them. - `hoist = false` takes precedence over `install.hoistPattern`, same as pnpm where `hoist=false` discards `hoist-pattern`. One caveat, shared with pnpm: the project root `node_modules` also sits above the store (`.bun` nests inside it), so packages linked there (direct dependencies, `publicHoistPattern` matches, workspace packages) remain resolvable from any store package. The docs state this and a test pins it. Note `hoistPattern = ""` (or any non-matching pattern) already suppresses the directory today; this adds the documented boolean switch for it, plus the stale-directory cleanup, which the pattern path does not do. ### Tests `test/cli/install/isolated-install.test.ts`, `describe("hoist")`: - `hoist = false` leaves no `node_modules/.bun/node_modules`; a store package resolves its declared deps through its own store entry, fails with `MODULE_NOT_FOUND` on an undeclared package, and can still reach a root-linked direct dependency (the pnpm-parity caveat above); root symlinks unchanged - a stale fallback directory from a previous (default) install is removed on the next `hoist = false` install, and the store entries the fallback symlinks pointed at survive - `hoist = false` wins over `hoistPattern = "*"` - `hoist = false` leaves `publicHoistPattern` hoisting intact - `.npmrc` `hoist=false` works All five fail on bun without this change (the fallback directory exists) and pass with it. Full `isolated-install.test.ts` and `public-hoist-pattern.test.ts` pass. Docs updated: `install.hoist` in bunfig.mdx, `hoist` in npmrc.mdx, and a section in isolated-installs.mdx (the layout diagram now shows the fallback directory). --- **no test proof** · iteration 3 · Platform-specific test(s) that do not run on this machine.

charset=UTF-8 Content-Transfer-Encoding: 8bit The install tests assembled bunfig.toml contents with template literals and conditional string concatenation, including manual backslash escaping so Windows paths survive TOML string syntax. Now that `Bun.TOML.stringify` exists, build these configs from plain objects instead. ### What changed - `VerdaccioRegistry.writeBunfig` and `authBunfig` in `test/harness.ts` now build an object and serialize it. The append-one-line-per-option string logic and the `.replaceAll("\\", "\\\\")` path escaping are gone; `Bun.TOML.stringify` skips `undefined` values, which replaces the conditionals. - `dummy.registry.ts` writes its per-context bunfig the same way. - Converted every inline site in `test/cli/install` that interpolated values or escaped backslashes by hand (about 100 sites across 19 test files). This includes the `registry = { url = ..., token = ... }` inline tables, which become nested objects emitted as `[install.registry]` sections, and dotted keys like `cache.disable = true`, which become nested tables. Both parse to the same data. - `minimum-release-age.test.ts`'s `createScannerConfig` helper now takes an object for extra install config instead of a raw TOML fragment, dropping its newline normalization. ### What deliberately did not change - Static TOML fixtures with no interpolation (e.g. `[install]\nlinker = "hoisted"`). - Tests where the raw TOML text is the point: `redacted-config-logs.test.ts` (intentionally malformed strings), invalid-config cases asserting parse errors, `bun-pack.test.ts` ignore-list fixtures. - `.npmrc` contents (ini, not TOML). - Sites that append a `[section]` header to an existing bunfig string; that stays layout-safe with the generated output, which ends with key/value lines under `[install]`. ### Verification For each converted site, the old string and the new `Bun.TOML.stringify` output were checked to parse to deep-equal objects (including backslash path cases). Ran the affected files locally with a debug build: - `bun-install.test.ts`, `bun-install-registry.test.ts`, `isolated-install.test.ts`, `bun-workspaces.test.ts`, `bun-publish.test.ts`, `bun-pm.test.ts`, `minimum-release-age.test.ts`, the security scanner matrix, and the remaining touched files: ~1550 tests pass. - `bun-install.test.ts` shows 14 failures locally both with and without this change; they are the network-dependent bitbucket/gitlab/external-tarball tests that cannot run in my sandbox and are unaffected by this diff. --- **no test proof** · iteration 1 · Platform-specific test-only change;

When the PTY master hits EOF, `Terminal::on_reader_finished` downgrades `this_value` to a weak ref and fires `exit`. The weak variant of `JsRef` is a raw `JSValue` with no liveness tracking, and the wrapper's cached callback slots are the only GC root of the `data`/`exit`/`drain` functions. Buffered input keeps flushing for another few hundred milliseconds after EOF (the kernel paces the discard), and when it finishes, `on_writer_ready` does `try_get()` on the weak ref and dispatches `drain` through whatever that address now holds: - if the wrapper was collected and its finalizer ran, the dispatch is silently skipped (the drain callback is lost); - if the cell was collected but not yet swept, the slot read returns a dead value and an unrelated, later-allocated function can be invoked as the drain callback (heap type confusion on release builds); - under a debug build the same window trips `member call on null 'JSC::ClassInfo'` in `Bun__JSValue__call` via `Terminal::on_writer_ready` <- `PosixStreamingWriter::on_poll`. Repro (roughly half of fresh processes lose the drain on an unfixed build): ```js let proc = Bun.spawn(["sh", "-c", "exit 0"], { terminal: { data() {}, exit() {}, drain() { console.log("drain"); } }, }); const big = Buffer.alloc(65536, 97); for (let i = 0; i < 16; i++) proc.terminal.write(big); // ~1MB the child never reads const exited = proc.exited; proc = null; await exited; // EOF: ref downgraded, drain still pending for (let i = 0; i < 4; i++) { // GC in the window collects the wrapper await new Promise(r => setTimeout(r)); Bun.gc(true); } ``` ### Fix Keep `this_value` strong until the terminal is actually idle: - `on_reader_finished` only downgrades when the writer has no buffered data (`maybe_downgrade_after_eof`). - `on_writer_ready` downgrades after dispatching `drain` (unless the callback buffered more data), and `on_writer_close` downgrades when buffered data is dropped on close/error, so the wrapper never outlives its last possible callback. - `write()` re-upgrades when it buffers data after EOF (e.g. a write from the `exit` callback), restoring the invariant that a pending drain implies a strong wrapper. - The Windows writer now clears `writer_has_buffered` when it reports `Drained`; previously the flag was never cleared on Windows, which under the new rule would have kept a post-EOF wrapper strong forever. The downgrade decision reads only `Cell` fields, so it is safe from the writer-parent callbacks that run while a writer borrow is live up the stack. A strong wrapper does not pin the event loop (the polls are unreffed on child exit as before), so processes still exit normally with input left unflushed. ### Verification New test in `test/js/bun/terminal/terminal.test.ts` runs ten fresh child processes sequentially, each buffering 1MB into a PTY child that exits immediately, forcing GC in the EOF-to-drain window, and requiring the drain callback to fire. Collection under conservative stack scanning is probabilistic per process (about half hit the window unfixed), so one process is not a reliable probe but ten sequential ones are; the loop stops at the first loss. - unfixed debug build: test failed 4/4 runs (first or second child loses the drain) - fixed debug build: passed 6/6 runs, ~5s - `test/js/bun/terminal/` (132 tests), `spawn.test.ts`, `spawn-ipc-gc.test.ts`, `spawn-many-teardown.test.ts` all pass - `cargo check -p bun_runtime --target x86_64-pc-windows-msvc` clean Not changed here: the generic `JsRef::Weak` liveness gap (a raw `JSValue`, no GC tracking) affects other consumers and deserves its own pass; the PTY fd retention after dropped sessions and the writer buffer retained by `close()` are separate issues. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

A callback that never returns (the fixture calls `process.exit(0)` inside it) stranded everything the ctx still owned: the generated `EVP_PKEY`, `KeyObjectData` refs, `BIGNUM`s. The leak is pre-existing; #36598 made it observable by routing `OPENSSL_malloc` through libc under ASAN. Whether LSan reported the other job types too was codegen luck (their pointers happened to be reachable by the conservative stack scan); `generateKeyPair`'s `EVP_PKEY` sits behind two FastMalloc indirections and was reported deterministically. ## Fix Make it structurally impossible for a job ctx to hold native resources across user JS: the native side never sees the callback. - `runFromJS` keeps its name (the JS-thread half, paired with the work-pool half `runTask`) but no longer receives the callback. It returns `JSCallbackArgs`, a small by-value type whose constructors are the only producers, so bodies read `return { err };` or `return { jsNull(), publicKey, privateKey };`. The extern "C" shims copy it through a typed out-pointer (C linkage cannot return a class type); the Rust side consumes it as a slice. - The Rust `extern_crypto_job!` plumbing does, in order: run `runFromJS` to produce the arguments, free the ctx (`ctx_deinit`), invoke the callback. The invariant lives in one place and applies to every job type. - Shutdown release: a completion task enqueued but not yet dispatched when `process.exit()` runs (exit racing the work pool) used to be re-queued at shutdown, stranding the ctx the same way. `AnyTaskJob` now carries an erased release entry and the shutdown release frees the job without running its completion. A completion posted after the final drain is not recoverable without joining the work pool (which would block exit); `test-crypto-op-during-process-exit.js` stays in `no-validate-leaksan.txt` for that sliver, now with an accurate comment. - The caught-export-exception paths encoded the `JSC::Exception` cell itself, so the callback's err argument was not the thrown Error (not `instanceof Error`, no `code`). They now use `Exception::value()`, matching node: JWK export of an unsupported curve surfaces `ERR_CRYPTO_JWK_UNSUPPORTED_CURVE`. No behavior change otherwise: - `Bun__EventLoop__runCallback{1,2,3}` were Rust's `EventLoop::run_callback` exported to C++. The plumbing now calls `run_callback` directly: same enter/exit bracketing, same pending-exception gate, same unhandled-exception reporting, same synchronous timing. This made `runCallback1`/`runCallback3` dead (the crypto bodies were their last callers), so their exports and declarations are deleted; `runCallback2` stays for the webview backends. - Callback arity is preserved per path (observable via `arguments.length`): error paths pass 1 arg, results 2, generateKeyPair success 3. - Exception paths are preserved: a throw out of argument production skips the callback and reports unhandled, as before. Each `runFromJS` checks its `ThrowScope` after every call that can throw (`RETURN_IF_EXCEPTION`), since the check that used to happen inside the nested `runCallbackN` call now happens after the C++ scope destructs; `BUN_JSC_validateExceptionChecks` verifies this on the asan lane. - The produced `JSValue`s live on the `then()` stack frame between production and invocation, which JSC's conservative scan covers; they are JS-heap values, so freeing the ctx first cannot invalidate them. - Perf: same number of FFI crossings, no allocation added. The Rust-native crypto jobs (pbkdf2, scrypt, random) already had the ordering property: they resolve promises or queue the callback via nextTick, so their ctx drops before user JS runs. The synchronous-callback extern jobs were the gap. ## Verification New tests in `crypto.key-objects.test.ts`: - `isASAN`-gated leak suite: children run with `BUN_DESTRUCT_VM_ON_EXIT=1` and `detect_leaks=1` (the asan lane's configuration) and call `process.exit(0)` from the callback of each job type: generateKeyPair (KeyObject and encrypted PEM outputs), sign, diffieHellman, hkdf, checkPrime, generateKey, plus an exit-before-completion-dispatch case (busy-spin so the queued completion is never dispatched). - An export-error test: `generateKeyPair('ec', { namedCurve: 'secp224r1', ...jwk encodings })` asserts the callback err is `instanceof Error` with code `ERR_CRYPTO_JWK_UNSUPPORTED_CURVE` (matches node; fails on main, which passes the Exception cell). Results: - unfixed build (src stashed): both generateKeyPair leak tests fail with the exact CI signature (`Direct leak of 24 byte(s)` in `EVP_PKEY_keygen` via `KeyPairJobCtx::runTask`) - fixed build: all pass, including under `BUN_JSC_validateExceptionChecks=1`, and ec/ed25519 keypair and verify probes run leak-clean as well - `AsyncLocalStorage-tracking.test.ts`: 74 pass, 0 fail (all async-context crypto fixtures, against both bun and node) - `crypto.test.ts` (369), `crypto.key-objects.test.ts` (117), and 37 node parallel files (`test-crypto-keygen*`, `test-crypto-sign-verify`, `test-crypto-hkdf`, `test-crypto-dh-stateless`, `test-crypto-*prime*`) all pass The break landed with #36598 (which made the leak visible); #36657 proposed clearing individual ctx fields before the callback, and this PR supersedes that approach with the ordering guarantee in the job plumbing instead of per-field resets. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

The failing assertion is: ``` expect(err1).toBe(""); received "\n" ``` The root cause is the install warning ``` warn: Slow filesystem detected. If is a network drive, consider setting $BUN_INSTALL_CACHE_DIR to a local folder. ``` which fires whenever creating and renaming a temp file in the install cache takes more than 100ms. `stderrForInstall` in the harness stripped the warning text but left its trailing newline, so the assertion received `"\n"`. Any test that asserts on stderr without that filter had the same latent flake, and the filter had to be remembered at every call site. ### Fix - Add a `BUN_DISABLE_SLOW_FILESYSTEM_WARNING` feature flag env var (same pattern as `BUN_DISABLE_SLOW_LIFECYCLE_SCRIPT_LOGGING`) that suppresses the warning, and skip starting the timer entirely when it is set. - Set it in `bunEnv` (harness) and in the CI runner's child environment, so every test-spawned bun is covered instead of only the call sites that remembered to filter. - Remove `stderrForInstall` and unwrap its ~70 call sites across the install tests; the filtering is dead weight once the warning cannot fire under the harness. - While in those helpers, read stdout, stderr, and the exit concurrently (`runBunInstall`, the publish helper) so a filled pipe buffer cannot block the child. ### Verification - Forced the slow path deterministically with an `LD_PRELOAD` shim that delays `renameat` past the 100ms threshold: without the env var the warning prints, with it stderr stays silent, and the old harness reproduces the exact `""` vs `"\n"` assertion diff from the alpine lanes. - The warning itself is unchanged for real users; the env var is only set by the test harness. - Install suites pass locally with the helper removed: bun-run-dir, catalogs, config-version, npmrc, bun-lockb, bun-publish, bun-link, bun-install-lifecycle-scripts (the few local failures are pre-existing debug-build environment issues that reproduce with pristine test files). --- **no test proof** · iteration 2 · Platform-specific test(s) that do not run on this machine.

Round-tripping a pyproject/Cargo-shaped file (`[tool.poetry]`, `[profile.release.package.foo]`) through parse/stringify injected standalone `[tool]`, `[profile]`, `[profile.release]`, `[profile.release.package]` lines. ### Fix In the stringifier (`src/runtime/api/TOMLObject.rs`), the `Layout::Table` arm wrote the header unconditionally before recursing. The header is now deferred and flushed lazily: - before the first keyval of the table's body, or - after the body when it is empty (`{ t: {} }` still emits `[t]`, since only the header materializes an empty table). A body that reaches a sub-section first drops the pending header instead: `[a.b]` alone implies `[a]`. `[[array]]` element headers are still written unconditionally since each one creates an element. No extra property-iteration pass, so getters are not invoked more than before. ``` stringify({ a: { b: { c: 1 } } }) -> "[a.b]\nc = 1\n" stringify({ t: { arr: [{ q: 1 }] }}) -> "[[t.arr]]\nq = 1\n" stringify({ t: {} }) -> "[t]\n" (unchanged) ``` ### Verification New assertions in `test/js/bun/toml/toml.test.ts` cover the skipped headers, skip-layout (`undefined`) properties not counting as keyvals, nested empty tables, an array-of-tables element whose body starts with a sub-table, and an exact pyproject/Cargo-shaped round-trip. They fail on the released build and pass with this change; the rest of the TOML suite (including the parse(stringify(parse)) suite) passes unchanged. --- **[review]** gate passed · iteration 1 · 2 files touched

Previously it threw a `BuildMessage`, which is not an `Error`, so `catch (e) { if (e instanceof SyntaxError) }` (or `e instanceof Error`) missed JSONC alone out of the whole parser family. Also: `Bun.JSONC.parse("")` now throws `SyntaxError` to match `JSON.parse("")` and `Bun.JSON5.parse("")`. The old behavior was accidental: `Bun.JSONC.parse("")` returned `{}` while `Bun.JSONC.parse(" ")` threw, because the internal parser's empty-file special case (there so an empty `tsconfig.json` / `package.json` parses as `{}`) leaked through the public API and whitespace-only input missed it. Empty input is invalid in every JSON dialect: the official JSONTestSuite lists it as a must-reject case (`n_structure_no_data`, moved to the invalid list in this PR), and VS Code's `jsonc-parser` reports a parse error on it. The internal tsconfig/package.json path keeps its lenient empty-file -> `{}` behavior (the check is in the `Bun.JSONC.parse` host function, not the shared parser). ## Repro ```js for (const [n, f] of [["JSON.parse", JSON.parse], ["Bun.JSON5.parse", Bun.JSON5.parse], ["Bun.JSONC.parse", Bun.JSONC.parse], ["Bun.YAML.parse", Bun.YAML.parse], ["Bun.TOML.parse", Bun.TOML.parse], ["Bun.JSONL.parse", Bun.JSONL.parse]]) { try { f("{ not valid"); } catch (e) { console.log(n, e.constructor.name, "instanceof Error:", e instanceof Error); } } ``` Before: ``` Bun.JSONC.parse BuildMessage instanceof Error: false ``` (everything else: `SyntaxError` / `true`) After: ``` Bun.JSONC.parse SyntaxError instanceof Error: true ``` ## Cause `src/runtime/api/JSONCObject.rs` threw `log.to_js(global, "Failed to parse JSONC")`, which materializes a `BuildMessage`. The sibling parsers (`TOMLObject.rs`, `JSON5Object.rs`, `YAMLObject.rs`) all build a `SyntaxError` via `global.create_syntax_error_instance(...)` from the first log message. TOML switched to this pattern in the parser rewrite; JSONC never did. ## Fix Mirror the TOML/JSON5 error path: match on `bun_parsers::Error` (`StackOverflow` -> stack overflow, `Alloc` -> OOM, everything else -> `SyntaxError` carrying the first log message text), and reject empty input up front with a `SyntaxError`. The `JSONC.parse` JSDoc in `packages/bun-types/bun.d.ts` now documents the throw (`@throws {SyntaxError}`, same as `TOML.parse`). --- **[review]** gate passed · iteration 0 · 3 files touched

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #36987 ### Repro With `linker = "isolated"`, installing a tarball dependency whose URL carries a query string: ```sh bun add 'tiny-query-package@http://localhost:8123/pkg.tgz?x=y' bun index.mjs ``` fails at runtime: ``` SyntaxError: Export named 'answer' not found in module '.../node_modules/.bun/tiny-query-package@http+++localhost+8123+pkg.tgz?x=y/node_modules/tiny-query-package/index.js'. ``` The same install without `?x=y` works. ### Cause The store path formatter maps `/ \ : #` to `+` but passes `?` through, so the literal query string ends up in the `.bun` store directory name. Module resolution treats `?` in a specifier as a query-string delimiter and truncates the path there, so the module is loaded from the wrong (truncated) path and named exports are missing. `?` is also an invalid filename character on Windows, where such installs fail outright. ### Fix Map `?` to `+` in `StorePathFormatter` (src/semver/lib.rs), the formatter that renders tarball URL resolutions into store directory names. The directory name is derived deterministically at install time, so no migration is needed; a reinstall produces the sanitized name. ### Verification New test in `test/cli/install/isolated-install.test.ts` serves a packed tarball from a local `Bun.serve`, installs it via a `?x=y` URL with the isolated linker, asserts the store entry name is `no-deps@http+++localhost++pkg.tgz+x=y`, and imports from the package at runtime. Fails on current main (store entry keeps `?x=y`, import breaks), passes with the fix.

From 80e6dbaf0f27efe2ed73e23339d31e0cbe66e619 Mon Sep 17 00:00:00 2001 From: robobun Date: Wed, 5 Aug 2026 23:59:05 -0700 Subject: [PATCH 139/304] node:net: fix ReferenceError for DEFAULT_IPV*_ADDR on happy-eyeballs localPort path (#30699) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #30697. ### Repro ```js const net = require('net'); const server = net.createServer(); server.listen(0, '127.0.0.1', () => { const client = new net.Socket(); client.on('error', err => console.error('Client error:', err.code || err.message)); client.connect({ port: server.address().port, host: 'localhost', localPort: 47293, lookup: (h, o, cb) => cb(null, [ { address: '::1', family: 6 }, { address: '127.0.0.1', family: 4 }, ]), }); }); ``` ``` Client error: DEFAULT_IPV6_ADDR is not defined at internalConnectMultiple (node:net:1093:39) at emitLookup (node:net:1024:48) … ``` ### Cause `src/js/node/net.ts` has two sibling functions that set up the local-bind address for a `net.Socket.connect({ localPort })` call: - `internalConnect` (single-address path) - `internalConnectMultiple` (happy-eyeballs / auto-select-family path) A previous fix (ec07ef83a2 — _"node:net: fix ReferenceError when localPort is passed to Socket connect"_) replaced broken `DEFAULT_IPV4_ADDR` / `DEFAULT_IPV6_ADDR` references in `internalConnect` with inline `"0.0.0.0"` / `"::"` string literals, but the copy in `internalConnectMultiple` was overlooked. Those two identifiers are not defined anywhere in the file, so any `net.connect({ localPort, … })` that enters the multi-address path throws a `ReferenceError` before any socket operation is attempted. The issue's own snippet uses `address: '::ffff:127.0.0.1'` as a connect option — Bun (and Node) ignore `address`, read `options.host = 'localhost'`, and on hosts where `localhost` resolves to both `::1` and `127.0.0.1` that triggers the multi-address path. ### Fix Replace the two undefined references with inline string literals, matching what `internalConnect` already does two functions above: ```diff if (localPort) { if (addressType === 4) { - localAddress = DEFAULT_IPV4_ADDR; + localAddress = "0.0.0.0"; } else { - localAddress = DEFAULT_IPV6_ADDR; + localAddress = "::"; } ``` ### Verification `test/js/node/net/node-net.test.ts` gains a `describe.each` pair that covers both branches (IPv4 first / IPv6 first) via a custom `lookup` returning two addresses plus a non-zero `localPort`. Without the fix the tests fail with the two distinct `ReferenceError`s; with the fix the connect completes normally. ``` $ bun bd test test/js/node/net/node-net.test.ts -t 30697 (pass) net.connect({ localPort }) with multiple lookup addresses #30697 > does not throw ReferenceError (IPv4 first (exercises the 0.0.0.0 branch)) (pass) net.connect({ localPort }) with multiple lookup addresses #30697 > does not throw ReferenceError (IPv6 first (exercises the :: branch)) ``` --- **no test proof** · iteration 6 · Platform-specific test(s) that do not run on this machine.

The fix adds Temporal handling to the shared special-object comparison in `bindings.cpp`, following the existing `JSDateType` case (Dates compare by internal number and ignore own properties): - same class required; different Temporal classes (or a Temporal vs a plain object) are never equal - `Instant`: exact time (nanoseconds) - `PlainDate`/`PlainDateTime`/`PlainYearMonth`/`PlainMonthDay`: ISO fields plus calendar - `PlainTime`: time fields - `ZonedDateTime`: exact time plus time zone plus calendar - `Duration`: field-wise, so `PT1H` and `PT60M` remain distinct values - extra own properties are ignored, matching `Date` - behavior is identical for strict and loose variants, `Bun.deepEquals`, `toEqual`, `toStrictEqual`, and `util.isDeepStrictEqual` (all share the template) Tests cover all eight types (equal and unequal pairs in both argument orders), cross-class pairs at the same moment, zone and calendar differences, nesting inside arrays/maps, the own-property parity with `Date`, and the expect matchers. The new assertions fail on the current release and pass with this change; `expect.test.js` (417 tests) and the Temporal suites are unaffected. Follow-up requested in #37018 review; once this lands, the TOML conformance suite generator there goes back to plain `toEqual`. --- **[review]** gate passed · iteration 1 · 2 files touched

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes a fuzzer-found abort (fingerprint `2f7e21cbc0aaac7b`). `JSC__JSValue__unwrapBoxedPrimitive` calls `toString`/`toNumber` on String and Number wrapper objects. Those re-enter JS when the wrapper has a `Symbol.toPrimitive` (or overridden `valueOf`/`toString`), so they can throw, for example when `Symbol.toPrimitive` returns an object. The binding ignored the pending exception and returned a value anyway, violating the zero-is-throw contract checked on the Rust side and tripping `releaseAssertNoException` in debug builds: ```js const s = new String(); s[Symbol.toPrimitive] = () => String; Bun.YAML.stringify(s); // ASSERTION FAILED: Unexpected exception observed ``` WebKit's `unwrapBoxedPrimitive` in JSONObject.cpp (which this was copied from) relies on its callers doing `RETURN_IF_EXCEPTION` right after; our extern C copy returns straight to Rust, so the check has to live in the binding itself. This adds a throw scope and returns empty when `toNumber`/`toString` throws, so the error surfaces as a normal JS exception from `Bun.YAML.stringify`, `Bun.TOML.stringify`, and `Bun.JSON5.stringify` (all reach this through `unwrap_boxed_primitive`). The regression test runs in a subprocess because the unfixed binary aborts the whole process in debug builds. Verified the spawned script exits 134 on the unfixed build and exits 0 with the expected TypeError output on the fixed one; yaml, toml, and json5 suites pass. --- **[stamp-90s]** gate passed · iteration 2 · 2 files touched

Seen in build 89504 on #37024, whose `test/js/bun/bun-object/deep-equals-temporal.test.ts` uses `[u-ca=hebrew]`: ``` Direct leak of 624 byte(s) in 1 object(s) allocated from: #1 icu_75::HebrewCalendar::clone() const #2 icu_75::Calendar::createInstance(icu_75::TimeZone*, icu_75::Locale const&, UErrorCode&) #3 ucal_open_75 #4 JSC::TemporalCore::buildCalendarTemplate(WTF::AbstractLocker const&, unsigned int) #5 JSC::TemporalCore::withCalendar(...) ``` The CI annotation titles this `direct leak of 624b in {closure#0} (src/jsc/JSValue.rs:1664:22)` because that is the first in-repo frame (the test-runner's `JSValue::call`); everything below it is WebKit/ICU. ### Cause `TemporalCore::withCalendar` (`vendor/WebKit/.../temporal/core/CalendarICUBridge.cpp`) keeps up to 8 open `UCalendar` templates in a process-lifetime `LazyNeverDestroyed` `TinyLRUCache`, one per calendar ID (non-ISO arithmetic, plus pure-ISO `PlainDateTime.prototype.with`, which reaches the same path unguarded); LRU eviction `ucal_close`s them, so the set is bounded. The `CalendarCacheEntry` that owns each `UCalendar` is `WTF_MAKE_TZONE_ALLOCATED` (bmalloc), which LSan does not scan, so the libc-allocated `UCalendar` (and the ICU `TimeZone` inside it) is reported as a direct leak even though it is reachable. Whether a given run aborts depends on whether some stale stack or register value still points at the ICU object when LSan scans at exit, hence the intermittence. This is the calendar twin of the already-suppressed `TemporalCore::withTimeZone` entry (same cache design, same TZone-allocated owner). ### Fix - Add a `leak:TemporalCore::buildCalendarTemplate` suppression to `test/leaksan.supp`, mirroring the `withTimeZone` entry. The pattern anchors on the template builder rather than `withCalendar` itself so that a future real leak inside one of the many op lambdas `withCalendar` runs would still be reported; every cached-template allocation carries the builder frame. (`withTimeZone` has no such builder frame, its `ucal_open` is inline, so that entry keeps its existing pattern.) - Drop the `test/no-validate-leaksan.txt` escape hatch #37024 added for `deep-equals-temporal.test.ts`, re-enabling leak validation for it; that file exercises the suppressed path on the asan lane. ### Verification On a debug ASAN build, running `bun test test/js/bun/bun-object/deep-equals-temporal.test.ts` under the CI leak-validation env (`BUN_DESTRUCT_VM_ON_EXIT=1`, `detect_leaks=1:abort_on_error=1`, repo suppression file): - with the new entry: clean exit, 5/5 runs - without it: LSan abort with the calendar-template stacks above, 3/3 runs A standalone probe exercising 8 non-ISO calendars plus pure-ISO `PlainDateTime.with` from a timer callback shows the same split (10/10 aborts without, 10/10 clean with; `print_suppressions=1` attributes exactly the ICU template allocations to the new entry). Top-level module code cannot reproduce this: its allocation stacks carry `JSC::JSModuleLoader::evaluateNonVirtual`, which the suppression file already covers wholesale. An ASAN-gated test pinning the entry was part of an earlier revision and was dropped per review; the re-enabled `deep-equals-temporal.test.ts` covers the path in CI instead. The Expect-wrapper shutdown leak mentioned in the dropped no-validate comment is a separate issue tracked in #32180: that is `bun test`'s own finalizer-owned memory, while this cache deliberately survives VM teardown, so #32180 would not prevent this report. --- **no test proof** · iteration 1 · docs-only change; test-proof not applicable --------- Co-authored-by: Dylan Conway --- test/leaksan.supp | 12 ++++++++++++ test/no-validate-leaksan.txt | 4 ---- 2 files changed, 12 insertions(+), 4 deletions(-) diff --git a/test/leaksan.supp b/test/leaksan.supp index 8fa44c178e3e..674c921b0629 100644 --- a/test/leaksan.supp +++ b/test/leaksan.supp @@ -136,3 +136,15 @@ leak:napi_internal_enqueue_finalizer # region, so the libc-allocated UCalendar it holds is reported as a direct # leak even though it is reachable and bounded. leak:TemporalCore::withTimeZone +# test/js/bun/bun-object/deep-equals-temporal.test.ts +# The calendar twin of withTimeZone above: up to 8 open UCalendars in a +# process-lifetime LazyNeverDestroyed TinyLRUCache, one per calendar ID +# (non-ISO arithmetic, plus pure-ISO PlainDateTime.prototype.with); LRU +# eviction ucal_closes them.

This indicates a bug in Bun, not your code. ``` The TOML parser builds dotted-key table chains iteratively, so there is no parse-time depth limit. The depth is first noticed when the module fetch hook converts the parsed AST to a JS object: `expr_to_js`'s recursion guard throws a RangeError on the VM and returns an error, which the hook consumed with a panic (`src/runtime/jsc_hooks.rs`, the JSON/TOML/YAML/JSON5 `ExportsObject` arm). ### Fix Return the error from the hook instead of panicking. The callers (`transpile_file`, `transpile_virtual_module`) already have a path for `Err(Js(_))` that takes the pending exception off the VM and surfaces it as the module error; this is the same idiom the `.napi` arm of the same function uses. A too-deep document in any of the object-exporting loaders (json/jsonc/toml/yaml/json5) now fails the import with a catchable RangeError, consistent with how `Bun.TOML.parse` reports too-deep inline tables. After the fix: ``` $ bun rt.js RangeError: Maximum call stack size exceeded. $ echo $? 1 ``` and `try { await import("./deep.toml") } catch (e) {}` observes the RangeError and the process continues. ### Tests Two cases in `test/js/bun/resolve/toml/toml.test.js`, both spawning a child (the unfixed bug kills the process): - static import of a deep dotted-header TOML exits 1 with `RangeError: Maximum call stack size exceeded` on stderr - dynamic import of the same file is catchable; the child logs the caught error name and exits 0 Both fail on the unfixed build (child aborts with the panic banner, exit 134) and pass with the fix. ### Why only TOML hits this TOML dotted table headers are the one syntax among the object-exporting loaders where nesting depth is built iteratively: `navigate_header` in `src/parsers/toml.rs` walks the `a.b.c...` segments in a plain loop, creating one nested object per segment with no recursion and no stack check, so the document parses at any depth and the first recursion over the result is the AST-to-JS conversion at import time. Every other way to nest is parsed recursively under a parse-time stack check and fails with an ordinary parse error long before the conversion could overflow (probed on the unfixed build at depths from 1k to 8M, no panic at any depth): - YAML: parse ceiling around 9k levels, error `ParseError while building ...` - JSON5: parse ceiling around 35k levels, same error - JSONC: explicit `JSON document is too deeply nested` around 65k levels - TOML inline tables: guarded in `parse_value`, which is why `Bun.TOML.parse` already threw RangeError for deep inline tables (existing test) - plain JSON: never reaches this code path at all (raw source bytes go to JSC's JSON parser) The parser recursion frames are several times larger than the conversion's, so the parse ceilings sit far below the roughly 200k levels the conversion needs to overflow: any document those parsers accept also converts. Tests for deep YAML/JSON5/JSONC documents would pin those parsers' existing parse-time limits, not this change, so the new tests cover the TOML dotted-header vector that actually reaches the fixed code. The fix itself sits at the choke point shared by all five loaders, so a parser change that opened a new window would throw instead of panicking. --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- src/runtime/jsc_hooks.rs | 23 +++++-- test/js/bun/resolve/toml/toml.test.js | 94 +++++++++++++++++++++++++++ 2 files changed, 111 insertions(+), 6 deletions(-) diff --git a/src/runtime/jsc_hooks.rs b/src/runtime/jsc_hooks.rs index 1a5f86b7ec84..88d32092d741 100644 --- a/src/runtime/jsc_hooks.rs +++ b/src/runtime/jsc_hooks.rs @@ -2737,12 +2737,23 @@ fn transpile_source_code_inner( // `SExpr` part; anything else is a parser bug. unreachable!("JSON/TOML/YAML parse result is always SExpr") }; - bun_js_parser_jsc::expr_to_js(&s_expr.value, global).unwrap_or_else(|e| { - bun_core::Output::panic(format_args!( - "Unexpected JS error: {}", - <&'static str>::from(e) - )) - }) + match bun_js_parser_jsc::expr_to_js(&s_expr.value, global) { + Ok(v) => v, + Err(e) => { + return Err(match e { + bun_ast::ToJSError::JSError => bun_jsc::JsError::Thrown, + bun_ast::ToJSError::JSTerminated => { + bun_jsc::JsError::Terminated + } + bun_ast::ToJSError::OutOfMemory => global.throw_out_of_memory(), + e => global.throw_error( + bun_jsc::CrateError::from(e), + "converting module to JavaScript", + ), + } + .into()); + } + } }; return Ok(OwnedResolvedSource::from(ResolvedSource { specifier: input_specifier.dupe_ref(), diff --git a/test/js/bun/resolve/toml/toml.test.js b/test/js/bun/resolve/toml/toml.test.js index c244e1be31ef..18c307078af7 100644 --- a/test/js/bun/resolve/toml/toml.test.js +++ b/test/js/bun/resolve/toml/toml.test.js @@ -1,4 +1,5 @@ import { expect, it } from "bun:test"; +import { bunEnv, bunExe, tempDir } from "harness"; import emptyToml from "./toml-empty.toml"; import tomlFromCustomTypeAttribute from "./toml-fixture.toml.txt" with { type: "toml" }; @@ -112,3 +113,96 @@ it("Bun.TOML.parse throws on deeply nested inline tables instead of crashing", ( "a = " + Buffer.alloc(depth * 6, "{ b = ").toString() + "1" + Buffer.alloc(depth * 2, " }").toString(); expect(() => Bun.TOML.parse(deepToml)).toThrow(RangeError); }); + +// Dotted paths (table headers and keys) nest iteratively in the parser, so the +// depth limit is only hit when the parsed AST is converted to a JS object at +// import time. +const deepDottedToml = "[" + Buffer.alloc(250_000 * 2, "a.").toString() + "a]\nd = 1\n"; +const deepDottedKeyToml = Buffer.alloc(250_000 * 2, "a.").toString() + "a = 1\n"; + +it.concurrent("importing a deeply nested table header throws instead of crashing", async () => { + using dir = tempDir("toml-deep-import", { + "deep.toml": deepDottedToml, + "main.js": `import d from "./deep.toml";\nconsole.log("unreachable");`, + }); + await using proc = Bun.spawn({ + cmd: [bunExe(), "main.js"], + env: bunEnv, + cwd: String(dir), + stderr: "pipe", + }); + const [stdout, stderr, exitCode] = await Promise.all([proc.stdout.text(), proc.stderr.text(), proc.exited]); + expect(stdout).toBe(""); + expect(stderr).toContain("RangeError: Maximum call stack size exceeded"); + expect(exitCode).toBe(1); +}); + +it.concurrent("dynamic import of a deeply nested table header is catchable", async () => { + using dir = tempDir("toml-deep-dynamic", { + "deep.toml": deepDottedToml, + "main.js": ` + try { + await import("./deep.toml"); + console.log("no-throw"); + } catch (e) { + console.log("caught:", e.name); + } + `, + }); + await using proc = Bun.spawn({ + cmd: [bunExe(), "main.js"], + env: bunEnv, + cwd: String(dir), + stderr: "pipe", + }); + const [stdout, stderr, exitCode] = await Promise.all([proc.stdout.text(), proc.stderr.text(), proc.exited]); + expect(stdout).toBe("caught: RangeError\n"); + expect(exitCode).toBe(0); +}); + +it.concurrent("importing a deeply nested dotted key throws instead of crashing", async () => { + using dir = tempDir("toml-deep-key", { + "deep.toml": deepDottedKeyToml, + "main.js": `import d from "./deep.toml";\nconsole.log("unreachable");`, + }); + await using proc = Bun.spawn({ + cmd: [bunExe(), "main.js"], + env: bunEnv, + cwd: String(dir), + stderr: "pipe", + }); + const [stdout, stderr, exitCode] = await Promise.all([proc.stdout.text(), proc.stderr.text(), proc.exited]); + expect(stdout).toBe(""); + expect(stderr).toContain("RangeError: Maximum call stack size exceeded"); + expect(exitCode).toBe(1); +}); + +it.concurrent("a moderately nested table header imports correctly", async () => { + // 1000 segments: comfortably below every stack limit, far above any real + // document.

Debug builds fail earlier with `panic: assertion failed: self.is_object()`. ### Cause `mock.results` is the live JSArray the native mock pushes into, so user code can place non-objects (or holes) in it. `jest_mock_return_object_type` in `src/runtime/test_runner/expect.rs` read each entry's `type` property with `fast_get`, which requires an object; for `undefined`/`null`/primitives it dereferences null. This is reachable from: - `toHaveReturned()` / `toHaveReturnedTimes(n)` (main counting loop) - `toHaveReturnedWith()` when building the "Some calls errored" failure message, which walks the same entries A sibling in `jsMockFunctionCall` (`src/jsc/bindings/JSMockFunction.cpp`): recording the call result does `RETURN_IF_EXCEPTION` inside the `setReturnValue` lambda, which only exits the lambda. If the internal push throws (e.g. `m.mock.results.length = 2**32-1` makes the next push exceed the max array length), the call continued with the exception pending, hitting `ASSERTION FAILED: Unexpected exception observed` in debug builds. ### Fix - Guard `jest_mock_return_object_type` with `is_object()` before the `fast_get`; non-object entries fall through to the existing "Expected value must be a mock function with returns: ..." error, matching how malformed object entries are already handled. - Add `RETURN_IF_EXCEPTION(scope, {})` after each `setReturnValue(...)` call site so a failed result push surfaces as the thrown RangeError instead of leaving the exception pending (and the implementation no longer runs after the record fails). ### Verification - Before: repro above segfaults (release) / aborts on `self.is_object()` (debug); the `results.length = 2**32-1; m()` case aborts debug builds with `Unexpected exception observed`. - After: `bun bd test` passes `test/js/bun/test/spyMatchers.test.ts` (150 pass), `test/js/bun/test/mock-fn.test.js` (78 pass), `test/js/bun/test/expect/toHaveReturnedWith.test.ts` (42 pass), and `test/js/bun/test/expect-toHaveReturnedWith.test.js` (13 pass). - New tests cover non-object entries, holes, the toHaveReturnedWith failure-message path, and the failed result push. --- src/jsc/bindings/JSMockFunction.cpp | 5 ++++ src/runtime/test_runner/expect.rs | 12 ++++++---- .../test/expect/toHaveReturnedWith.test.ts | 23 +++++++++++++++++++ test/js/bun/test/mock-fn.test.js | 15 ++++++++++++ test/js/bun/test/spyMatchers.test.ts | 23 +++++++++++++++++++ 5 files changed, 74 insertions(+), 4 deletions(-) diff --git a/src/jsc/bindings/JSMockFunction.cpp b/src/jsc/bindings/JSMockFunction.cpp index bbe197002249..8acd839ffdaa 100644 --- a/src/jsc/bindings/JSMockFunction.cpp +++ b/src/jsc/bindings/JSMockFunction.cpp @@ -925,6 +925,7 @@ JSC_DEFINE_HOST_FUNCTION(jsMockFunctionCall, (JSGlobalObject * lexicalGlobalObje } setReturnValue(createMockResult(vm, globalObject, "incomplete"_s, jsUndefined())); + RETURN_IF_EXCEPTION(scope, {}); auto topExceptionScope = DECLARE_TOP_EXCEPTION_SCOPE(vm); @@ -954,16 +955,19 @@ JSC_DEFINE_HOST_FUNCTION(jsMockFunctionCall, (JSGlobalObject * lexicalGlobalObje case JSMockImplementation::Kind::ReturnValue: { JSValue returnValue = impl->underlyingValue.get(); setReturnValue(createMockResult(vm, globalObject, "return"_s, returnValue)); + RETURN_IF_EXCEPTION(scope, {}); return JSValue::encode(returnValue); } case JSMockImplementation::Kind::ReturnThis: { setReturnValue(createMockResult(vm, globalObject, "return"_s, thisValue)); + RETURN_IF_EXCEPTION(scope, {}); return JSValue::encode(thisValue); } case JSMockImplementation::Kind::RejectedValue: { JSValue rejectedPromise = JSC::JSPromise::rejectedPromise(globalObject, impl->underlyingValue.get()); RETURN_IF_EXCEPTION(scope, {}); setReturnValue(createMockResult(vm, globalObject, "return"_s, rejectedPromise)); + RETURN_IF_EXCEPTION(scope, {}); return JSValue::encode(rejectedPromise); } default: { @@ -973,6 +977,7 @@ JSC_DEFINE_HOST_FUNCTION(jsMockFunctionCall, (JSGlobalObject * lexicalGlobalObje } setReturnValue(createMockResult(vm, globalObject, "return"_s, jsUndefined())); + RETURN_IF_EXCEPTION(scope, {}); return JSValue::encode(jsUndefined()); } diff --git a/src/runtime/test_runner/expect.rs b/src/runtime/test_runner/expect.rs index dabe89cb2812..ac844bbcd697 100644 --- a/src/runtime/test_runner/expect.rs +++ b/src/runtime/test_runner/expect.rs @@ -3069,10 +3069,14 @@ pub mod mock { } pub(crate) fn jest_mock_return_object_type(global_this: &JSGlobalObject, value: JSValue) -> JsResult { - if let Some(type_string) = value.fast_get(global_this, bun_jsc::BuiltinName::Type)?

On a debug build it asserts: ``` ASSERTION FAILED: !(attributes & PropertyAttribute::Accessor) PropertySlot.h(226) ``` Same outcome for class constructors (`spyOn(K, "prototype")` then `new K()` or `instanceof`). ### Cause `spyOn`'s accessor branch (`JSMock__jsSpyOn` in `src/jsc/bindings/JSMockFunction.cpp`) handles non-callable values by writing a `GetterSetter` into the target with `putDirectAccessor`. For a `JSFunction` target, the `prototype` property is served by `JSFunction::getOwnPropertySlot`'s special case, which returns the stored slot as a plain value and ignores the `Accessor` attribute. The raw `GetterSetter` cell therefore escapes to script as the value of `Foo.prototype`, and anything that touches it crashes. Other targets are unaffected: the same accessor install on plain objects, module namespaces, and host constructors goes through the normal property path and behaves. ### Fix In the accessor branch, refuse when the target is a `JSFunction` and the key is `prototype`, matching Jest: ``` error: Cannot spy on the `prototype` property because it is not a function ``` A function whose `prototype` has been reassigned to a function value is unaffected: that case takes the data-property spy path (`putDirect`), which the special-cased read handles fine, so it keeps working. ### Verification New tests in `test/js/bun/test/mock-fn.test.js` cover: function and class constructor targets throw and are left intact (`new Foo()`, methods still work), arrow functions (no prototype property) throw, and a function-valued `prototype` can still be spied on and restored. The throw test fails on unfixed bun (spyOn succeeds there) and passes with the fix; the full file (79 tests) passes, and spying on plain objects with a `prototype`-named property and on host constructors like `Array` is unchanged. --- **[review]** gate passed · iteration 0 · 2 files touched

Fixes `bun build` silently emitting a truncated bundle (exit code 0) when the printer cannot print a module. **Repro:** ```sh python3 -c "print('[' + 'a.'*250000 + 'a]'); print('d = 1')" > deep.toml bun build deep.toml ``` On current releases this exits 0 and prints only the 43-byte export stub with none of the `var` declarations: ```js export { a, deep_default as default }; ``` The bundle is corrupt and importing it throws at runtime. `bun build --no-bundle deep.toml` has the same problem (empty output, exit 0), and `Bun.build` reports `success: true`. **Cause:** TOML dotted headers build arbitrarily deep object chains iteratively, so the parser succeeds. The printer's recursion guard then trips while printing and `print_with_writer_and_platform` correctly returns `PrintResult::Err(Error::StackOverflow)`, but every consumer of a `CompileResult` swallowed the error: - `CompileResult::code()` / `into_code()` in `bundle_v2.rs` mapped `Err` to `b""` - `print_result_take_code` in `postProcessJSChunk.rs` mapped `Err` to `Box::default()` - the transform-only path dropped per-file errors entirely (`Ok(None) | Err(_) => continue` in `process_resolve_queue`) so the linker joined the truncated part into the chunk and reported success. **Fix:** - `generateChunksInParallel.rs`: after parallel codegen completes, scan the compile results; any `PrintResult::Err` (or failed CSS result) is logged as a build error on the offending source and the build fails with `Error::PrintError`. This single choke point covers `bun build` and `Bun.build`. - `transpiler.rs` (`--no-bundle`): an error from `build_with_resolve_result_eager` that was not already logged (print errors, unlike parse errors, add nothing to the log) is reported instead of skipped, so the CLI exits non-zero. The scan is gated on `!IS_DEV_SERVER`: the bake dev server's caller chain maps any error from this function to `AllocError` and then `.expect("oom")`s (`finish_from_bake_dev_server` / `on_after_decrement_scan_counter`), so failing there would abort the whole server on one unprintable file. The dev server keeps its pre-existing behavior for such a part (the part's code is dropped) until print failures get routed per-file like parse failures. `StackOverflow` maps to `Maximum call stack size exceeded while generating code for this file`, matching the parser's existing message for too-deep source ([#31242](https://github.com/oven-sh/bun/pull/31242), [#31333](https://github.com/oven-sh/bun/pull/31333)); other printer errors report their error name. Failing the build matches the runtime behavior for the same document (a `RangeError: Maximum call stack size exceeded` from the guarded converters), and mirrors what the parser already does for source that is too deep to parse: the guard makes printing fail, and a failed print must fail the build rather than emit output that does not round-trip. Errors are deduplicated by source index: without code splitting a failing shared module is printed once per chunk that includes it, and the error should stay per-file like parse errors. The same scan also catches failed CSS results. Those were swallowed the same way: `composes` on a non-simple selector makes the CSS printer fail, and released builds emit a stylesheet with the entire body dropped (only the `/* file */` banner) and exit 0. That case now fails the build too; the CSS warning that precedes it states the specific reason. Making the error message itself carry the CSS reason (the generation sites currently collapse everything to `PrintError`) is a possible follow-up. After this change: ``` $ bun build deep.toml error: Maximum call stack size exceeded while generating code for this file at deep.toml $ echo $? 1 ``` ### How did you verify your code works? New tests (all fail on the released binary, pass with this change): - `test/bundler/cli.test.ts`: `bun build deep.toml` exits 1 with the error and produces no partial output on stdout; same for `--no-bundle`. - `test/bundler/bun-build-api.test.ts`: `Bun.build` returns `success: false`, zero outputs, and a `BuildMessage` carrying the error. Full `test/bundler/cli.test.ts`, `bun-build-api.test.ts`, `bundler_edgecase.test.ts`, `bundler_loader.test.ts`, `bundler_splitting.test.ts`, and `css/css-modules.test.ts` pass with the debug build. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Fixes `node:crypto`'s `getArrayBufferOrView` helper (used by `Certificate.verifySpkac`, `Certificate.exportPublicKey`, and `Certificate.exportChallenge`), which threw `ReferenceError: key is not defined` when given a public or private `KeyObject`: ```js const crypto = require("node:crypto"); const { publicKey } = crypto.generateKeyPairSync("ec", { namedCurve: "P-256" }); crypto.Certificate.verifySpkac(publicKey); // before: ReferenceError: key is not defined // after: TypeError [ERR_INVALID_ARG_TYPE]: The "spkac" argument must be of type string // or an instance of ArrayBuffer, Buffer, TypedArray, or DataView. Received an instance of KeyObject ``` The helper had a `KeyObject` branch whose error message interpolated `key.type`, but the parameter is named `buffer`; `key` does not exist in that scope. The branch appears to have been copied from Node's `prepareSecretKey` (where the parameter is named `key`) without renaming. ### Why remove the branch instead of fixing the variable name? Node's `getArrayBufferOrView` in `lib/internal/crypto/util.js` has no `KeyObject` handling at all (checked v16.20.2, v18.19.0, v20.19.4, v22.16.0, v24.13.0, v26.3.0): every `KeyObject`, secret ones included, falls through to `ERR_INVALID_ARG_TYPE`. On Node v26.3.0: ``` > crypto.Certificate.verifySpkac(publicKey) TypeError [ERR_INVALID_ARG_TYPE]: The "spkac" argument must be of type string or an instance of ArrayBuffer, Buffer, TypedArray, or DataView. Received an instance of PublicKeyObject ``` Keeping a repaired branch would still diverge from Node twice over: secret `KeyObject`s would be silently accepted and non-secret ones would get `ERR_CRYPTO_INVALID_KEY_OBJECT_TYPE` instead of `ERR_INVALID_ARG_TYPE`. So the helper now mirrors Node's line for line, with the hand-rolled `new TypeError` + `error.code` replaced by the shared `$ERR_INVALID_ARG_TYPE` constructor. That also fixes the message format for non-KeyObject junk input: `Received type number (42)` instead of `Received 42`, without the nonstandard `ERR_INVALID_ARG_TYPE:` message prefix. This helper has no other callers; cipher/hash/sign paths use the separate C++ `getArrayBufferOrView` and are unaffected. ### How did you verify your code works? Added tests in `test/js/node/crypto/node-crypto.test.js` covering all three `Certificate` methods with public, private, and secret `KeyObject`s, the non-buffer error message, and the still-working `Buffer`/string happy path.

(cost 4) Bun.password.hashSync("pw", { algorithm: "argon2id", timeCost: 2 ** 32 + 2 }); // t=2 ``` Meanwhile `{ port: 65617 }` correctly threw `Expected "port" to be an integer between 0 and 65535`, because 65617 stays in i32 range. ### How did you fix it? Validate the double as an in-range integer before narrowing, at each site: - `udp_socket.rs`: bind `port` (0..=65535), `connect.port` (1..=65535), and `parse_addr` for `send`/`sendMany` (1..=65535). `parse_addr` now throws for out-of-range ports instead of rewriting them to 0: on Linux the port-0 sockaddr happened to fail with EINVAL, but on Windows `send()` reported success for a datagram that never went anywhere. Port 0 stays allowed inside `parse_addr` because the multicast membership/interface callers pass a literal 0. - `PasswordObject.rs`: bcrypt `cost` (4..=31), argon2 `timeCost`/`memoryCost` (1/8 ..= u32 max). Existing error messages are kept for the previously-rejected cases (`Memory cost must be at least 8`, `Time cost must be greater than 0`); wrapping and fractional values now throw instead of hashing with a truncated parameter. - `dgram.ts`: `Socket.prototype.bind(cb)` kept the callback in its port variable and `port || 0` forwarded the function to `Bun.udpSocket`, relying on the old ToInt32 coercion to turn it into 0 (Node does the same dance via ToUint32 in its native layer). Normalize a function first argument to "no port" in the JS layer; caught by `test-dgram-socket-buffer-size.js` and the other `bind(cb)` tests in the Node suite. `node:dgram`'s send/connect paths validate ports in JS (`ERR_SOCKET_BAD_PORT`) before reaching this code, so they were unaffected. ### Tests - `test/js/bun/udp/udp_socket.test.ts`: wrap values added to the existing connect.port case list, a new bind case list (4294967377, -4294967215, 2^53, 80.5, NaN, Infinity), and a send/sendMany test that binds a real socket and proves `2 ** 32 + server.port` throws instead of delivering to `server.port`. - `test/js/bun/util/password.test.ts`: wrap and fractional values for `cost`, `timeCost`, `memoryCost` across both `hash` and `hashSync`. All fail on the released binary (10 udp + 2 password failures) and pass with this change; the full udp, dgram, and password suites plus all 75 `test-dgram-*` Node parallel tests pass with the debug build. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

Signature: ``` error: Condition was not met after 100 GC attempts at gcUntil (test/napi/napi-app/module.js:24:13) ``` Of 136 captured occurrences, 126 point at the final poll of `test_remove_wrap_lifetime_with_strong_ref` (after `napi_reference_unref` drops the refcount to 0, the test polls until the weak ref reports the object as collected) and 10 at the equivalent poll in `test_wrap_lifetime_with_strong_ref`. ## Cause The object is never collected because it is pinned by JSC's conservative stack/register scan, not because the reference is wrongly strong. Evidence: - `NapiRef::unref` correctly drops the strong handle at refcount 0. - A heap snapshot taken inside a failing run shows the `{foo:"bar"}` object alive with zero incoming edges and no labeled GC root: no heap retainer exists. - The failure is per-process bimodal. Instrumented runs on windows-x64 (where the old fixture fails 19 times in 750 runs, about 2.5% per run, independent of env) show the final poll either succeeds on attempt 0 or fails all 100 attempts. A pinned address stays pinned no matter how many more GCs run in that loop, so `gcUntil`'s 100 attempts are 100 correlated coin flips of the same coin. JS-level mitigation of the stack state does not work either: the conservative scan covers the region from the GC entry stack pointer up to the stack origin, and JS code can only overwrite stack below its own frames (verified: a stack-clobbering recursion before each GC attempt changed nothing). Node does not hit this because V8 clears weak handles from precise marking. ## Fix Test-side, in the shared napi-app fixture (runs identically under Node and Bun, output parity preserved): - `test_remove_wrap_lifetime_with_strong_ref` now retries with a freshly allocated object, up to 4 attempts. A conservative pin holds one specific address, so attempts are independent (~2.5% each on the worst platform, so 4 attempts put the residual around 4e-7). The abandoned ref from a failed attempt leaks deliberately; its wrap was removed so no finalizer touches the fixture's global state. - Collection polls use a new native `is_wrapped_object_collected()` which checks `napi_get_reference_value` against NULL in native code instead of materializing the referent as a JS value in every iteration of the poll loop. - The expected-to-fail GC loops (proving a strongly referenced object is NOT collected) run 10 iterations instead of 100. Ten consecutive full GCs prove non-collection just as well, and this halves the test's wall time: 4.9s to 0.9s with a release build, which also gives slow (debug/ASAN) lanes headroom against the per-test timeout. - The `try { gcUntil(...) } catch` expected-failure pattern becomes `assert(await tryGcUntil(...) === false)`. `test_wrap_lifetime_with_strong_ref` (the remaining 10 of 136 occurrences) cannot retry safely because `create_wrap`'s finalizer routes through fixture-global state (`ref_to_wrapped_object`), and a collected leftover object from a previous attempt would delete the current attempt's ref. Making that retry-safe needs the finalizer to carry its own ref, which is a larger fixture refactor; its failure rate is ~2.5% of builds vs ~30% for the test overall, so this PR takes the 93%. ## Verification - windows-x64, old fixture: 19 failures in 750 runs of `test_remove_wrap_lifetime_with_strong_ref`. Fixed fixture: 0 failures in 600 runs. - Full `test/napi/napi.test.ts` passes on linux-x64 (release and debug ASAN builds) and windows-x64, including the Node output-parity comparisons. - `bun bd test test/napi/napi.test.ts --timeout=60000 -t napi_wrap`: 7 pass. --- **no test proof** · iteration 1 · docs-only change; test-proof not applicable --- test/napi/napi-app/module.js | 93 ++++++++++++++++++------------- test/napi/napi-app/wrap_tests.cpp | 19 +++++++ 2 files changed, 73 insertions(+), 39 deletions(-) diff --git a/test/napi/napi-app/module.js b/test/napi/napi-app/module.js index 997e15c4f6d6..702ed54fc87e 100644 --- a/test/napi/napi-app/module.js +++ b/test/napi/napi-app/module.js @@ -5,9 +5,14 @@ const asyncFinalizeAddon = require("./build/Debug/async_finalize_addon.node"); const testReferenceUnrefInFinalizer = require("./build/Debug/test_reference_unref_in_finalizer.node"); const testReferenceUnrefInFinalizerExperimental = require("./build/Debug/test_reference_unref_in_finalizer_experimental.node"); -async function gcUntil(fn) { - const MAX = 100; - for (let i = 0; i < MAX; i++) { +// Returns true once fn() is true, false if it still isn't after `max` GCs. +// Collection of any *particular* object is not guaranteed under JSC: a +// conservative stack/register scan can pin one address for the entire process, +// so callers that need a collection to happen should retry with a freshly +// allocated object (see test_remove_wrap_lifetime_with_strong_ref) rather +// than raising `max`. +async function tryGcUntil(fn, max = 100) { + for (let i = 0; i < max; i++) { await new Promise(resolve => { setTimeout(resolve, 1); }); @@ -18,10 +23,16 @@ async function gcUntil(fn) { global.gc(); } if (fn()) { - return; + return true; } } - throw new Error(`Condition was not met after ${MAX} GC attempts`); + return false; +} + +async function gcUntil(fn, max = 100) { + if (!(await tryGcUntil(fn, max))) { + throw new Error(`Condition was not met after ${max} GC attempts`); + } } nativeTests.test_napi_class_constructor_handle_scope = () => { @@ -908,15 +919,8 @@ nativeTests.test_wrap_lifetime_with_strong_ref = async () => { assert(nativeTests.get_wrap_data(object) === 42); object = undefined; - // still referenced by native module so this should fail - try { - await gcUntil(() => nativeTests.was_wrap_finalize_called()); - throw new Error("object was garbage collected while still referenced by native code"); - } catch (e) { - if (!e.toString().includes("Condition was not met")) { - throw e; - } - } + // still referenced by native module, so these GCs must not collect it + assert((await tryGcUntil(() => nativeTests.was_wrap_finalize_called(), 10)) === false); // can still get the value using the ref assert(nativeTests.get_wrap_data_from_ref() === 42); @@ -940,41 +944,52 @@ nativeTests.test_remove_wrap_lifetime_with_weak_ref = async () => { object = undefined; // ref will stop working once the object is collected - await gcUntil(() => nativeTests.get_object_from_ref() === undefined); + await gcUntil(() => nativeTests.is_wrapped_object_collected()); + assert(nativeTests.get_object_from_ref() === undefined); // finalizer shouldn't have been called assert(nativeTests.was_wrap_finalize_called() === false); }; nativeTests.test_remove_wrap_lifetime_with_strong_ref = async () => { - let object = { foo: "bar" }; - assert(createWrapWithStrongRef(object) === object); - - assert(nativeTests.get_wrap_data(object) === 42); - - nativeTests.remove_wrap(object); - assert(nativeTests.get_wrap_data(object) === undefined); - assert(nativeTests.get_wrap_data_from_ref() === undefined); - assert(nativeTests.get_object_from_ref() === object); + // A conservative stack/register scan can pin any one address for the whole + // process, so "this object gets collected" is not guaranteed for a + // particular object.

That only works when this is the first `require("node:zlib")` in the process: zlib captures `buffer.kMaxLength` at module load, matching Node (lib/zlib.js destructures `kMaxLength` from `require('buffer')` at load). When another zlib test file has already loaded `node:zlib`, the cached module holds the original limit and nothing throws. CI spawns one process per test file, so this only bites local directory runs. ## Fix Test-only: each codec's checks now run the patch-then-require sequence in a fresh child process via a small fixture (`zlib-kmaxlength-fixture.cjs`). Coverage is unchanged: brotli/inflate/gunzip/unzip, sync and async. One child per codec keeps the per-test cost around 2s under ASAN debug builds, within the default test timeout even on 2 cores. Making `src/js/node/zlib.ts` read `buffer.kMaxLength` at call time instead would fix the in-process case but diverge from Node, which captures at load. The ported upstream tests (`test-zlib-kmaxlength-rangeerror.js` and its brotli/zstd variants) depend on capture-at-load: they restore `buffer.kMaxLength` right after loading zlib and still expect `RangeError`, so they would start failing under call-time reads. The fixture is a file rather than an inline `bun -e` script: eval mode exposes builtin module names as lazy globals, and a top-level `const zlib` in the eval'd source materializes that global during declaration instantiation, loading `node:zlib` before the script body (and before the `kMaxLength` patch) runs. Filed separately as #36994. ## Verification - Before: `USE_SYSTEM_BUN=1 bun test test/js/node/zlib/` fails 8, the file alone passes 8 - After: directory run passes 457 with 0 fail; the file alone passes under `bun test` and `bun bd test` (ASAN debug), including pinned to 2 CPUs where the per-test margin is about 1s against the 5s default timeout --- **[stamp-90s]** gate passed · iteration 0 · 2 files touched

Every candidate was grepped for bare-name, quoted-string, and `$`-prefixed references before deletion; items referenced from generated bindings, `.classes.ts` files, attribute-macro exports (`uws_callback(export = ...)`), or `extern "C"` surfaces were left alone. The vendored WebKit tree is part of the reference scan as well: `Bun__errorInstance__finalize` was initially removed here, then restored once the darwin LTO link surfaced its `__attribute__((weak))` reference from JSC's `ErrorInstance.cpp` (weak references satisfy non-LTO links silently). ### Rust - `bun_install::Error`: variants `FileTooBig`, `ProcessFdQuotaExceeded`, `ReadOnlyFileSystem`, `FileSystem`, `FileBusy` were never constructed (the same-named live variants belong to `bun_runtime`'s separate error enum; `node_fs.rs` maps onto that one) - `hosted_git_info::Representation::Ssh`: every ssh-flavored protocol maps to `Sshurl` - `FromTextLockfileError::InvalidSemver` plus its only mention, an unreachable match arm in `bun.lock.rs` (`ParseError::InvalidSemver` stays and is still produced) - `MigratePnpmLockfileError::{PnpmLockfileInvalidOverride, PnpmLockfileInvalidPatchedDependency}`: never produced by the pnpm migration - windows-shim `FailReason::InvalidShimDataSize`: no size check produces it - `bun_event_loop::EventLoopTimer::TimerCallback` struct, its `Tag` variant, and the dispatch arm in `runtime/dispatch.rs`: nothing ever constructed one, so the tag could never be dispatched - `bun_dns::Family::Unix`: neither the string map nor the JS numeric mapping yields it (`AF_UNIX` on the result path is a different, live match) - MySQL wire structs: write-only fields `OKPacket::{warnings, info, session_state_changes}`, `EOFPacket::warnings`, `StmtPrepareOKPacket::warning_count`, `LocalInfileRequest::filename`. The wire reads stay so packet parsing consumes the same bytes; only the dead stores and their zero-initializers are gone. ### C++ bindings - `NodeValidator.cpp`: host functions `jsFunction_validateString` / `jsFunction_validateFunction` / `jsFunction_validateBoolean` and their declarations. Their `$newCppFunction` bindings were removed in an earlier sweep (#36937 removed the sibling trio); the `V::validate*` overloads they forwarded to are live and stay. - `ImportMetaObject.cpp`: `jsFunctionRequireResolve` and its only callee `functionRequireResolve` (static, 76 lines; the live `require.resolve` is built elsewhere) - `BunString.cpp`: `BunString__toWTFString` (no Rust-side caller; the regenerated `cpp.rs` drops the import) - `sliceAnsi.cpp`: never-instantiated `struct HyperlinkInfo` (`wrapAnsi.cpp`'s `HyperlinkState` is the live one) - `NodeFSStatFSBinding.cpp`: `getStatFSPrototype`, a template with zero instantiations - Declarations with no definition: `functionBunPeek` / `functionBunPeekStatus` (BunObject.h), `callBakeResponse` / `constructBakeResponse` (JSBakeResponse.cpp), `jsSqlStatementGetHasMultipleStatements` (JSSQLStatement.cpp), `bn_set_words` (dh-primes.h) - Commented-out blocks from 2023-2024: the `ErrorCaptureStackTrace` experiment in BunProcess.cpp, the `deleteProperty` block in JSAbortSignal.cpp, the `setOnEachMicrotaskTick` block in BakeGlobalObject.cpp ### Built-in JS internals Export-default entries no requirer ever destructures (verified against every `require()` site, C++ `getDirect` lookups, and `test/` imports of internal modules); backing functions that are still used in-file stay: - `internal/repl/node-shims.js`: `isWritable`, `runScriptInThisContext`, `kEmptyObject`, `addAbortListener`, `promisify` (none of repl.js / internal/repl/* touch them) - `internal/streams/iter/from.ts`: `normalizeAsyncSource`, `normalizeSyncSource`, `normalizeSyncValue`, `primitiveToUint8Array` - `internal/sql/sqlite.ts`: `SQLCommand`, `commandToString`, `parseSQLQuery`, `SQLiteQueryHandle` (sole requirer pulls only `SQLiteAdapter`) - `internal/sql/shared.ts`: `parseDefinitelySqliteUrl`, `buildDefinedColumnsAndQuery`, `normalizeSSLMode` - `internal/http1_server_fallback.ts`: `createHttp1FallbackResponseHandle`, `kHttp1ActiveRequests` - one-line entries: `setTid` (trace_events), `FixedCircularBuffer` (fixed_queue), `EXECUTION_CONTEXT_ID` (inspector/cdp), `defineCustomPromisify` (promisify), `SQLQueryStatus` (sql/query), `allUint8Array` (streams/iter/utils) ### Build config and orphaned files - `scripts/build/flags.ts`: defines `IS_BUILD`, `WITH_BORINGSSL=1`, `STATICALLY_LINKED_WITH_BMALLOC=1`, `BUN_SINGLE_THREADED_PER_VM_ENTRY_SCOPE=1` have zero readers in `src/`, `packages/`, or the pinned WebKit checkout (WebKit reads the lowercase `STATICALLY_LINKED_WITH_bmalloc`, which is not what we were defining) - `src/runtime/ffi/libtcc1.a.macos-aarch64`: prebuilt 30KB archive from 2022 with zero references (`libtcc1.c` is embedded via `include_bytes!` and compiled at runtime) ### Verification - `cargo check --workspace` and `bun run rust:check-all` (10 ok, 0 failed) so platform-gated uses would have surfaced - full `bun bd` debug build, which regenerates codegen and relinks the C++ side - smoke tests: `test/js/bun/repl/repl.test.ts` (148 pass), `test/cli/install/migration/migrate.test.ts` (20 pass), `test/js/sql/wire-frames.test.ts`, `test/js/sql/sql-mysql-clean-reentry.test.ts` against MariaDB, `test/js/sql/adapter-override.test.ts`, fixed-queue node tests, plus module-load smokes for repl/stream/trace_events/http2/util - `test/internal/source-lints/` suite passes, including the new `dead-symbols-install-sql-bindings.test.ts` that pins these removals - checked against all open robobun PRs at deletion granularity: a planned removal of the install lifecycle-script time log was dropped from this PR because #36587 restores that feature, and the mysql `CharacterSet` collation table plus the `Bun__CryptoHasherExtern__*` helpers were left alone after verification showed they are referenced (`label()` at MySQLConnection.rs:661, C++ wrappers in CryptoUtil.cpp) ### Verified-dead but deliberately not removed (for a future pass, pending maintainer judgment) - windows-shim `read_without_launch` / `FromBunShellContext` (~120 lines): zero callers, but the crate docs describe it as the staged in-process path for the shell - `src/runtime/bake/incremental_visualizer.html` + `memory_visualizer.html` (~808 lines): the `/_bun/incremental_visualizer` route that served them was never ported from the Zig dev server, while the websocket topic plumbing they rely on is live and tested - `src/jsc/bindings/webcrypto/*.idl` (29 files, ~1055 lines): nothing in the build reads `.idl`, but they are maintained alongside the handwritten bindings as spec reference (SubtleCrypto.idl was edited in July) --- **[review]** gate passed · iteration 2 · 43 files touched

When the sibling module exports a matching name it silently loads the wrong file. The explicit `"./"` form resolved correctly. ### Cause A relative specifier of `.` or `..` (or one ending in `/.` or `/..`) explicitly names a directory, but `check_relative_path` joins it with the source directory and the normalization strips the dot segments, producing `/project/lib` with no memory that the specifier named a directory. `load_as_file_or_directory` then tries file candidates first and finds `/project/lib.ts` by extension probing. An explicit `"./"` works because the join preserves a trailing slash, which keeps the file-candidate probe from matching. ### Fix In `check_relative_path`, when the specifier explicitly names a directory (`.`, `..`, or ends in `/.` or `/..`), re-append the trailing separator to the joined path so it takes the same directory-only route `"./"` already takes (index file or `package.json` main, never sibling file candidates). This matches Node (`trailingSlashRegex` in `Module._findPath`) and esbuild; `require(".")` and the bundler go through the same path. ### Verification New tests in `test/js/bun/resolve/resolve.test.ts` cover `.`, `./`, `./.`, `..`, `require(".")`, `package.json` `main` resolution, and a guard that `../lib` (no dot segment) still prefers the sibling file. They fail on the unfixed build (5 failures) and pass with this change. Also ran the full `resolve.test.ts`, `test/bundler/resolver/`, `bundler_edgecase.test.ts`, and `test/js/node/module/` suites: all green. --- **no test proof** · iteration 3 · Platform-specific test(s) that do not run on this machine.

Found during an audit of the fetch HTTP client's terminal-dispatch ordering (the same family as the `Option::unwrap() on a None value` panic at `FetchTasklet::callback`'s `http` unwrap: a freed client's stage guards live in recycled memory and can re-dispatch a stale result into a freed tasklet). ASAN, unfixed build (second `fetch.preconnect` to the same origin): ``` ==ERROR: AddressSanitizer: heap-use-after-free ... READ of size 1 ... thread T3 (HTTP Client) READ: HTTPClient::start_ lib.rs:2868 (request_stage check after connect() returned) freed: AsyncHTTP::on_async_http_callback_raw AsyncHTTP.rs:788 (terminal dispatch deallocates the clone) <- HTTPClient::on_preconnect lib.rs:4412 <- HTTPClient::first_call lib.rs:1983 <- HTTPContext::connect (pooled keep-alive reuse) <- HTTPClient::start_ ``` ### Cause The first preconnect parks its socket in the keep-alive pool. A second preconnect to the same origin takes the pooled socket inside `HTTPContext::connect`, which calls `on_open`/`first_call` synchronously; for a preconnect-only client that runs `on_preconnect`, whose terminal `result_callback.run` frees the `ThreadlocalAsyncHTTP` clone that embeds the `HTTPClient`. Control then returns into `start_`, which still dereferences the freed client: the `request_stage == Pending` abort-tracker check, and `complete_connecting_process()`, which also writes a flag into the freed block and, if the block was recycled, can re-dispatch a terminal result into a freed consumer. Synchronous connect *failures* already avoid exactly this: `start_` sets a defer flag, `fail()` only records the failure while the flag is set, and `complete_connecting_process()` performs the dispatch as the last action of `start_`. The preconnect success dispatch bypassed that mechanism. ### Fix Route the preconnect completion through the same deferral: `on_preconnect` still unregisters the abort tracker and releases the socket to the pool, but when the defer flag is set it leaves the terminal stage recorded and returns; `complete_connecting_process()` then dispatches the preconnect result as its last action, after which every caller returns without touching the client. The fresh-connect path (empty pool, socket opens from the event loop) is unchanged: the flag is already clear, so `on_preconnect` dispatches directly as before. Since the flag now defers a success dispatch as well, `defer_fail_until_connecting_is_complete` is renamed to `defer_terminal_dispatch_until_connecting_is_complete` (single file, no external surface). ### Verification Two tests in `test/js/web/fetch/fetch-preconnect.test.ts`, both spawning a child that loops `fetch.preconnect` against a local listener and asserting the loop actually reused the parked socket (connection count stays low) rather than opening fresh connections: - ASAN test (`skipIf(!isASAN)`; the release build corrupts silently): unfixed debug+ASAN build crashes with the `heap-use-after-free` above on the first pooled reuse, every run; fixed build passes with `connections: 1`. - Slot-release test (all builds, `BUN_CONFIG_MAX_HTTP_REQUESTS=4`): each preconnect holds a request slot until its completion dispatch runs, so a dropped deferred dispatch pins all four slots and the final `fetch()` can never start. Verified it fails (the fetch starves and the child hangs) when the deferred dispatch arm is removed while the early return stays, a breakage the ASAN test alone cannot observe. - `test/js/bun/http/proxy.test.ts` (68), `proxy-stress-lifecycle` + `proxy-stress-errors` (146), `proxy-stress-adversarial` + `proxy-stress-concurrent` (182), and `fetch-abort-queued.test.ts` all pass on the fixed ASAN build. - `test/js/web/fetch/fetch.test.ts`: identical failure set to an unfixed baseline in the same container (pre-existing debug/ASAN timeouts and utf16+gc failures, verified by running them against the unfixed build). --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

No certificate needed: ```js Object.getOwnPropertyDescriptor(require("node:crypto").X509Certificate.prototype, "validFromDate"); ``` ``` ASSERTION FAILED: !(attributes & PropertyAttribute::CustomAccessorOrValue) JavaScriptCore/runtime/PropertyDescriptor.cpp(183) JSC::PropertyDescriptor::setAccessorDescriptor ``` Anything that walks descriptors hits it too: `Object.getOwnPropertyDescriptors(X509Certificate.prototype)`, `util.inspect(proto, { showHidden: true })`, test utilities that snapshot descriptors. Release builds are unaffected because get/put check the `CustomAccessor` bit first. ### Cause The `validFromDate` and `validToDate` rows in `JSX509CertificatePrototypeTableValues` used the attribute mask `CustomAccessorOrValue` (= `CustomAccessor | CustomValue`) instead of `CustomAccessor`. Every neighbouring accessor row (`validFrom`, `validTo`, `ca`, `fingerprint`, ...) uses `CustomAccessor`. When `getOwnPropertyDescriptor` reifies the accessor it strips the `CustomAccessor` bit, but the stray `CustomValue` bit survives and trips the assertion in `setAccessorDescriptor`. ### Fix Use `CustomAccessor` on both rows, matching the rest of the table. ### Verification - Repro above aborts a debug build on main (exit 134) and is fine after the fix. - New tests in `test/js/node/crypto/x509.test.ts` read the descriptors (single and whole-prototype walk) and call the extracted getters on an instance; they abort the debug build before the fix and pass after. - `test/js/node/crypto/x509.test.ts`, `x509-subclass.test.ts`, `test-crypto-x509.js`, and `test-tls-getcertificate-x509.js` all pass with the fix. --- .../bindings/JSX509CertificatePrototype.cpp | 4 +-- test/js/node/crypto/x509.test.ts | 30 +++++++++++++++++++ 2 files changed, 32 insertions(+), 2 deletions(-) diff --git a/src/jsc/bindings/JSX509CertificatePrototype.cpp b/src/jsc/bindings/JSX509CertificatePrototype.cpp index 5bd309ab0850..d226225d1b68 100644 --- a/src/jsc/bindings/JSX509CertificatePrototype.cpp +++ b/src/jsc/bindings/JSX509CertificatePrototype.cpp @@ -82,9 +82,9 @@ static const HashTableValue JSX509CertificatePrototypeTableValues[] = { { "toLegacyObject"_s, static_cast(PropertyAttribute::Function), NoIntrinsic, { HashTableValue::NativeFunctionType, jsX509CertificateProtoFuncToLegacyObject, 0 } }, { "toString"_s, static_cast(PropertyAttribute::Function), NoIntrinsic, { HashTableValue::NativeFunctionType, jsX509CertificateProtoFuncToString, 0 } }, { "validFrom"_s, static_cast(PropertyAttribute::ReadOnly | PropertyAttribute::CustomAccessor), NoIntrinsic, { HashTableValue::GetterSetterType, jsX509CertificateGetter_validFrom, 0 } }, - { "validFromDate"_s, static_cast(PropertyAttribute::ReadOnly | PropertyAttribute::CustomAccessorOrValue), NoIntrinsic, { HashTableValue::GetterSetterType, jsX509CertificateGetter_validFromDate, 0 } }, + { "validFromDate"_s, static_cast(PropertyAttribute::ReadOnly | PropertyAttribute::CustomAccessor), NoIntrinsic, { HashTableValue::GetterSetterType, jsX509CertificateGetter_validFromDate, 0 } }, { "validTo"_s, static_cast(PropertyAttribute::ReadOnly | PropertyAttribute::CustomAccessor), NoIntrinsic, { HashTableValue::GetterSetterType, jsX509CertificateGetter_validTo, 0 } }, - { "validToDate"_s, static_cast(PropertyAttribute::ReadOnly | PropertyAttribute::CustomAccessorOrValue), NoIntrinsic, { HashTableValue::GetterSetterType, jsX509CertificateGetter_validToDate, 0 } }, + { "validToDate"_s, static_cast(PropertyAttribute::ReadOnly | PropertyAttribute::CustomAccessor), NoIntrinsic, { HashTableValue::GetterSetterType, jsX509CertificateGetter_validToDate, 0 } }, { "verify"_s, static_cast(PropertyAttribute::Function), NoIntrinsic, { HashTableValue::NativeFunctionType, jsX509CertificateProtoFuncVerify, 1 } }, }; diff --git a/test/js/node/crypto/x509.test.ts b/test/js/node/crypto/x509.test.ts index 64613d4131cf..3ef775eec16c 100644 --- a/test/js/node/crypto/x509.test.ts +++ b/test/js/node/crypto/x509.test.ts @@ -104,3 +104,33 @@ describe("X509Certificate.subjectAltName", () => { expect(cert.toLegacyObject().subjectaltname).toBe(""); }); }); + +describe("X509Certificate.prototype property descriptors", () => { + // validFromDate/validToDate were registered as CustomAccessorOrValue instead of + // CustomAccessor, so reading their descriptors asserted in debug builds. + test("validFromDate and validToDate descriptors read like their siblings", () => { + const proto = X509Certificate.prototype; + for (const name of ["validFromDate", "validToDate", "validFrom", "validTo"] as const) { + const desc = Object.getOwnPropertyDescriptor(proto, name)!; + expect({ ...desc, get: typeof desc.get }).toEqual({ + get: "function", + set: undefined, + enumerable: true, + configurable: true, + }); + } + + const all = Object.getOwnPropertyDescriptors(proto); + expect(typeof all.validFromDate.get).toBe("function"); + expect(typeof all.validToDate.get).toBe("function"); + }); + + test("extracted validFromDate/validToDate getters work on an instance", () => { + const cert = new X509Certificate(wildcardSanCertPem); + const getFrom = Object.getOwnPropertyDescriptor(X509Certificate.prototype, "validFromDate")!.get!; + const getTo = Object.getOwnPropertyDescriptor(X509Certificate.prototype, "validToDate")!.get!; + expect(getFrom.call(cert)).toBeInstanceOf(Date); + expect(getFrom.call(cert)).toEqual(cert.validFromDate); + expect(getTo.call(cert)).toEqual(cert.validToDate); + }); +}); From 7624109d6ba10bbbd575246bcb00df4ffd099de1 Mon Sep 17 00:00:00 2001 From: Dylan Conway Date: Thu, 6 Aug 2026 13:21:11 -0700 Subject: [PATCH 155/304] Remove dead peechy schema scaffolding, bun-wasm, and write-only option types (#37068) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ### What does this PR do? Deletes legacy code left over from the old peechy-schema / `bun-wasm` effort that never shipped. Nothing generates code from the `.peechy` files anymore — the Rust structs and the checked-in JS decoder have both diverged from them — and `packages/bun-wasm` has had no build path since the Makefile was removed, so all of it was dead weight that made the option types look like a wire format they no longer are. - Removes `packages/bun-wasm/`, `src/api/schema.peechy`, `src/analytics/schema.peechy`, and the `src/api` npm scaffolding. - Inlines the three small analytics enums into `bun_analytics` and reuses `bun_core::Environment::ARCH` instead of a duplicate `Architecture` enum. - Drops option plumbing that was only ever written, never read: `ResolveMode`, `CssInJsBehavior`, `LoadedEnvConfig`/`Env::to_api`, the never-populated `Env.defaults` list and the framework-defaults half of `copy_env_for_define`, `NpmRegistry::dupe`, the `SourceMap`/`Packages` aliases, and `bun_core::schema`. - Removes comments promising a future peechy codegen pass. No behavior change intended. Follow-ups (separate PRs): switch the dev-mode error page payload from the peechy binary encoding to JSON (which also lets `src/api/schema.js` and the `peechy` npm dep go), and collapse the `schema::api` mirror enums (`Loader`/`Target`/`SourceMapMode`/…) onto their real counterparts. ### How did you verify your code works? Debug build + `cargo clippy --workspace`; cross-checked `bun_analytics`/`bun_crash_handler` for linux-gnu, linux-musl, windows, freebsd and android targets. Drove `bun-debug` through each touched surface and confirmed identical output to before: `bun build --env=inline|PUBLIC_*|disable`, `--define`, `--sourcemap`, `--packages`, multi-entry `--splitting`, `bun exec`, `bun run` (shell), `.npmrc` scoped registry (request hit the scoped URL with its token), `/bun:info`, the `development: true` error page, and the crash-report platform line. `test/bundler/bundler_env.test.ts` passes. --- .aikido | 1 -

JSC brand-checks DOMAttribute getters centrally (`PropertySlot::customGetter` throws for a foreign receiver), but nothing checks custom setters: `JSObject::putInlineSlow` invokes the setter for any put whose receiver merely inherits the slot. The three setters did `uncheckedDowncast(thisValue)` and wrote through the result. Bun's own `Readable.fromWeb` path (`internal/streams/native-readable.ts`) assigns `stream.$bunNativePtr = ptr` on a node `Readable` with an ordinary put. Once user code grafts `ReadableStream.prototype` into the node stream prototype chain, that put walks the chain into the setter with the `Readable` as `this`, and `m_nativePtr.set()` writes a JSValue at an offset that lands inside the `Readable`'s inline property storage. ```js import { Readable } from "node:stream"; import { EventEmitter } from "node:events"; const snap = o => Object.fromEntries(Reflect.ownKeys(o).map(k => [String(k), Object.prototype.toString.call(o[k])])); const before = snap(Readable.fromWeb(new Response("x").body)); Object.setPrototypeOf(EventEmitter.prototype, ReadableStream.prototype); const after = snap(Readable.fromWeb(new Response("x").body)); for (const k in before) if (before[k] !== after[k]) console.log("clobbered own slot", k, before[k], "->", after[k]); ``` On Bun 1.4.0 this prints `clobbered own slot Symbol(kCapture) [object Boolean] -> [object BlobInternalReadableStreamSource]` and exits 0 (silent type-confused write). ASAN debug builds abort in `reportZappedCellAndCrash` under `uncheckedDowncast` called from `jsReadableStreamPrototype_nativePtrSetter`. ### Fix - `JSReadableStream.cpp`: all six private-name accessors now `dynamicDowncast` the receiver and throw the matching `throwVMDOMAttributeGetterTypeError` / `throwDOMAttributeSetterTypeError` on a mismatch, same as the check JSC already applies on the getter path. - `native-readable.ts`: assign `$bunNativePtr` with `$putByIdDirectPrivate`, which defines the own property without consulting the prototype chain, so `Readable.fromWeb` keeps working even when the prototype chain has been rearranged. ### Verification New test in `test/js/node/stream/node-stream.test.js` runs the repro in a subprocess, asserts no own slot is clobbered, and that the stream still delivers its data. It fails on the unfixed build (release: clobbered slot; ASAN debug: abort) and passes with this change. Full `node-stream.test.js`, `web/streams/streams.test.js`, `process-stdin.test.ts`, and `child-process-stdio.test.js` pass. --- **no test proof** · iteration 2 · Platform-specific test(s) that do not run on this machine.

Lets a YAML alias refer to an anchored collection that contains it (`&a [*a]`, `&a\nself: *a`), so `Bun.YAML.parse` can build cyclic objects and the output of `YAML.stringify` on a cyclic value round-trips. Previously any such alias failed with "Unresolved alias". How it works: every sequence/mapping node is allocated (empty) in the AST store as soon as its opening token is seen, and its entries are moved into it once parsed. While it is being parsed, an alias for its anchor is handed the final node pointer directly — no fix-up pass. Anchors still bind when their node completes, and the fallback to enclosing anchored collections only applies to aliases that would otherwise be unresolved, so every document that parsed before produces the same result (the anchor-redefinition corner cases are pinned to their previous outputs in tests). Also: - Importing/bundling `.yaml` and `pnpm-lock.yaml` migration reject cyclic aliases ("Cyclic aliases are only supported by Bun.YAML.parse"), since those paths print or clone the tree. - `<<:` merging from a collection that is still being parsed is an error. - The alias-expansion budget walk cuts cycles. - One inconsistency fixed along the way: `&k {a: 1}: v` now anchors the flow-mapping key, matching how `&k [a]: v` was already handled. Not covered (unchanged): an anchor on the line *before* a flow collection (`&a` ⏎ `[*a]`) is not visible inside it, because whether it belongs to the collection or to a `[..]: v` block mapping is only known after the closing bracket. ### How did you verify your code works? New cases in `test/js/bun/yaml/yaml.test.ts` (block/flow sequences and mappings, explicit keys, merge keys, multi-document, module import rejection, stringify round-trips) — they fail on 1.4.0 and pass with `bun bd test test/js/bun/yaml/yaml.test.ts`; `yaml-test-suite.test.ts` and the other YAML test files are unchanged and passing.

charset=UTF-8 Content-Transfer-Encoding: 8bit Assigning `onmessage` or `onerror` through a Proxy of the global object segfaults the process on 1.4.0: ```js new Proxy(globalThis, {}).onmessage = null; // panic: Segmentation fault at address 0x10 ``` The same crash fires for `onerror`, for the sloppy-mode sandbox idiom `with (new Proxy(globalThis, {})) { onmessage = function () {} }`, and inside a worker (`new Proxy(self, {}).onmessage = ...`), where it takes down the whole process. ### Cause `onmessage`/`onerror` are installed on the global with `putDirectCustomAccessor(..., 0)`, which makes them CustomValue properties. For a CustomValue slot, JSC's put-on-receiver path (`JSObject::definePropertyOnReceiverSlow`) invokes the custom setter with the receiver as `thisValue`. When the receiver is a ProxyObject rather than the global, `uncheckedDowncast` in `setGlobalOnMessage`/`setGlobalOnError` (ZigGlobalObject.cpp) type-confuses the Proxy and dereferences a bogus `eventTarget()`. ### Fix Cast `thisValue` with `dynamicDowncast` in the four onmessage/onerror callbacks and fall back to `defaultGlobalObject(lexicalGlobalObject)` when the receiver is not a global. The assignment then installs the handler on the real global of the running realm, which matches Deno's behavior for this pattern and keeps the `with (proxy)` sandbox idiom working. In a worker, the handler lands on the worker's own global scope. ### Verification New tests in `test/js/web/web-globals.test.js`: - main thread: install, dispatch, and clear `onmessage`/`onerror` through `new Proxy(globalThis, {})`, plus the `with` scope variant - worker: a worker whose message handler is installed via `new Proxy(self, {})` echoes a message back Both fail with the segfault on the released binary and pass with this change. The second commit trims the pre-existing `crypto.randomUUID` fast-path loop in the same file from 45,000 `expect()` calls to one assertion; it was overrunning the 5s per-test budget on debug builds. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## What Fixes `test/cli/hot/watch-many-dirs.test.ts` ("handles 129 directories being updated simultaneously"), which has been failing on main and across PR CI runs on Linux with: ``` error: EISDIR reading "/tmp/.../hot-many-dirs_.../dir-0072/index.js" error: EBADF reading "/tmp/.../hot-many-dirs_.../dir-0009/index.js" ``` followed by the 30s test timeout (the failed reload never prints the expected output). Seen red on main builds 86133/86209/86347 and in many PR runs, e.g. [build 89567](https://buildkite.com/bun/bun/builds/89567). The race is timing-sensitive: it reproduced once in 80 local runs of an unmodified release build (with the exact EBADF + EISDIR + timeout signature), while loaded CI machines hit it regularly. ## Cause `bun --hot` re-transpiled a changed module by reading through a file descriptor snapshotted from the watcher's watchlist (`ImportWatcher::snapshot_fd_and_package_json`). The snapshot copies the fd number under the watcher mutex, but the read in `transpiler.rs:read_file_with_allocator` happens after the mutex is released. Concurrently, the watcher thread's `flush_evictions` closes stored descriptors under that same mutex. On Linux, a write to a file inside a watched directory produces both a file event and a directory event; the directory-event arm in `hot_reloader.rs` evicts the watched file's entry (to handle atomic saves that replace the inode). With 129 directories the inotify events span multiple batches, so a reload triggered by batch N snapshots a descriptor that batch N+1's eviction then closes: - fd closed before the read: `EBADF reading ""` - fd number recycled by one of the resolver's many `openat(O_DIRECTORY)` calls: `EISDIR reading ""` The mutex ordering added previously (`flush_evictions` before `enqueue`, snapshot under the mutex) only closed the same-event window; nothing can serialize a later batch's eviction against a read that happens after the snapshot returns. Reading through the stored fd was also wrong after atomic saves (pre-rename inode, stale contents), which is why the entrypoint already had a workaround skipping it. ## Fix Reloads now always open the file by path, and the watchlist keeps sole ownership of its stored descriptor: - `snapshot_fd_and_package_json` becomes `snapshot_package_json`; the stored fd is never handed out for reads. This removes the race structurally and makes the entrypoint's open-by-path workaround universal, so it is deleted. - `Watcher::add_file` no longer replaces a valid stored fd on the already-watched branch (it only upgrades fd-less entries inserted by `add_file_by_path_slow`, e.g. the `--hot` entrypoint, so the directory-event recovery path keeps working). The old overwrite dropped the replaced descriptor without closing it, leaking one fd on the entrypoint per reload. - `add_file` now returns `FdOwnership` saying whether it adopted the caller's descriptor; the transpiler handoff sites, `AsyncModule`, the bundler's plugin watch path, and `add_file_by_path_slow` close the descriptor when the watcher did not take it. The bundler's `watcher_data` path intentionally ignores the outcome and keeps today's behavior, since its descriptor can be borrowed from the resolver's entry cache. The fd-per-reload behavior is locked in by a new deterministic test in `watch-many-dirs.test.ts` that counts `/proc//fd` entries for the entrypoint and an edited dependency across 15 reloads. On an unfixed build the entrypoint gains exactly one fd per reload (+15); with the fix both counts are stable. (The remaining per-reload directory-handle growth comes from the resolver's `DirEntry` cache and is addressed separately in #36675.) ## Verification - New test fails on an unfixed build (`entryDelta: 15`) and passes with the fix. - The race fix is structural rather than statistical: after this change the transpiler only ever reads descriptors it opened itself, so the closed-by-eviction read cannot occur. Empirically, "handles 129 directories" failed 1/80 runs on an unfixed release build and passed 40/40 (plus 12/12 debug ASAN) runs on a fixed one. - `test/cli/hot/hot.test.ts` (12), `test/cli/hot/watch.test.ts` (2), `test/cli/watch/` (7), `test/bake/dev/hot.test.ts` (11, including DEV:hot-9), `test/js/bun/util/filesystem_router.test.ts` (33), `test/cli/test/test-changed.test.ts` (20) all pass on a debug ASAN build. - `bun run rust:check-all`: 10/10 target combos clean. The race predates any recent change (the fd-reuse pattern and evicting close shipped with #30412 and were inherited from the original design); CI frequency rose recently with timing shifts. The open #36675 fixes the adjacent resolver-side leaks and includes a different change to the same `add_file` branch; this PR supersedes that hunk by never replacing the stored fd at all. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

This breaks the Microsoft-recommended TypeScript 7 coexistence setup (typescript-eslint etc.). ### Cause `PackageManager.known_npm_aliases` maps alias names (the left side of `"alias": "npm:target@range"`) to their aliased versions. In `enqueue_dependency_with_main_and_success_fn` the lookup key for an `npm:` dependency is its `realname()`, which for an alias dependency is the registry target name. So the nested `npm:typescript@^6` (target name `typescript`) matched the root's alias entry keyed by the alias name `typescript`, and since `6.0.2` satisfies `^6`, the dependency was rewritten to `@typescript/typescript6@6.0.2`. That substitution exists to dedupe a plain dependency whose name collides with an alias installed elsewhere in the tree (covered by the existing test "should get npm alias with matching version"). It is wrong for a dependency that is itself an `npm:` alias: its target names an explicit registry package, and it installs under its own folder name, so there is no hoisting collision to dedupe. ### Fix Skip the `known_npm_aliases` substitution when the dependency is itself an `npm:` alias (`is_alias`), mirroring the existing `is_alias` exclusion for overrides a few lines below. Plain-dependency dedupe behavior is unchanged. ### Verification New test in `test/cli/install/bun-install.test.ts` ("should resolve nested npm: alias to its registry target, not a same-named alias"): root aliases `baz` to `bar@0.0.2`, and `bar` depends on `"baz-old": "npm:baz@>=0.0.1"`. Before the fix, `baz-old` resolves back to `bar` (1 package installed); after, it resolves to the real `baz@0.0.3`. Fails on bun 1.4.0, passes with this change. The original repro now matches npm: ```console $ bun install && bun -e "const ts=require('typescript'); console.log(ts.version, typeof ts.Extension)" 2 packages installed 6.0.3 object ``` Verified with both the hoisted and isolated linkers, and the existing alias tests in bun-install.test.ts (22) still pass. ### Updated existing test `bun-install-registry.test.ts` "transitive file dependencies > from non-hoisted workspace dependencies" asserted the old behavior: the root aliases `"file-dep": "npm:a-dep@1.0.1"`, so pkg1's `"aliased-file-dep": "npm:file-dep@1.0.1"` was silently redirected to `a-dep` and the aliased transitive file dependency the test describes (`// aliased. has "file-dep": "file:."`) was never actually installed. It now resolves to the real `file-dep@1.0.1` with a nested copy under pkg1 (13 -> 15 packages, matching npm); the expectations now assert the nested package contents and its `file:` link. --- **no test proof** · iteration 6 · Platform-specific test(s) that do not run on this machine.

That left the field write-only: assigned at every construction site and threaded through `parse_maybe`, `ParseResult::empty_with`, and the four cold loader helpers (`parse_data_loader`, `parse_text_loader`, `parse_md_loader`, `parse_wasm_loader`) without ever being read, as review on that PR pointed out. This deletes the field, the `parse_maybe` local that fed it, and the pass-through parameters. The fd the parse opened still reaches the watcher handoff sites through `ParseOptions::file_fd_ptr`, which was already written from the same `entry.fd` on the same line. The comment in `AsyncModule.rs` that named the deleted field is reworded. No behavior change, dead-code removal only, so there is no fail-before test to write. While auditing the touched loader paths, the runtime `.md` module loader turned out to have no coverage at all (the existing md tests only exercise the `Bun.markdown` API), so this adds tests locking it in: `import`/`require` of a `.md` file yields the rendered HTML as the default export, and an empty `.md` file produces a module with no default export (the `empty_with` path). ## Verification - `cargo check -p bun_bundler` and a full debug build pass. - On the debug build: `test/js/bun/md/md-edge-cases.test.ts` (84 pass, including the new import tests), `test/cli/hot/watch-many-dirs.test.ts` (2 pass, including the fd-count test added in #37050), `test/cli/hot/hot.test.ts` (12 pass), `test/js/bun/resolve/toml` + `yaml` + `jsonc` (21 pass), `test/bundler/bundler_loader.test.ts` (45 pass). --- src/bundler/transpiler.rs | 26 ++-------------- src/jsc/AsyncModule.rs | 2 +- test/js/bun/md/md-edge-cases.test.ts | 46 +++++++++++++++++++++++++++- 3 files changed, 48 insertions(+), 26 deletions(-) diff --git a/src/bundler/transpiler.rs b/src/bundler/transpiler.rs index c09e93d70d40..0a1df1b9abb4 100644 --- a/src/bundler/transpiler.rs +++ b/src/bundler/transpiler.rs @@ -848,7 +848,6 @@ pub struct ParseResult<'a> { pub loader: options::Loader, pub ast: bun_ast::Ast<'a>, pub already_bundled: AlreadyBundled, - pub input_fd: Option, pub empty: bool, // `PendingResolution` does not yet // derive `MultiArrayElement` (lives in `bun_resolver`, derive macro is in @@ -890,7 +889,6 @@ impl<'a> ParseResult<'a> { loader: options::Loader::File, ast: bun_ast::Ast::empty_in(arena), already_bundled: Default::default(), - input_fd: None, empty: true, pending_imports: Default::default(), runtime_transpiler_cache: None, @@ -905,7 +903,6 @@ impl<'a> ParseResult<'a> { arena: &'a bun_alloc::Arena, source: bun_ast::Source, loader: options::Loader, - input_fd: Option, source_contents_backing: resolver::cache::Contents, ) -> Self { ParseResult { @@ -913,7 +910,6 @@ impl<'a> ParseResult<'a> { loader, ast: bun_ast::Ast::empty_in(arena), already_bundled: AlreadyBundled::None, - input_fd, empty: true, pending_imports: Default::default(), runtime_transpiler_cache: None, @@ -1353,7 +1349,6 @@ impl<'a> Transpiler<'a> { // the unique live `&mut Log` for the duration of the parse. let log: &mut bun_ast::Log = self.log_mut(); - let mut input_fd: Option = None; // Owns the heap allocation backing `source.contents` for the // non-shared-buffer file-read and `data:` URL paths.

Byte and substring search over `&[u8]` now goes through `bun_core::strings` (Google Highway kernels, runtime CPU dispatch) everywhere, and the routes around it are denied so it stays that way. libcore's slice/str searchers never reach highway (`iter().position(|&b| b == x)` is a byte-at-a-time loop, `<[u8]>::contains` is scalar SWAR, `windows(n).position()` is O(n·m); we also build Rust with `-Ctarget-cpu=nehalem` on x64), and Rust can't override inherent slice methods, so most sites ported from `bun.strings.indexOfChar` / `std.mem.indexOfScalar` had quietly gone scalar. **The slow methods being rooted out** (what each compiles to on `&[u8]`; throughput measured on aarch64, 1 MiB haystack, needle absent — the SIMD memchr baseline on the same machine is ~126 GB/s): | method | what it actually does | measured | |---|---|---| | `s.iter().position(\|&b\| b == x)` / `.rposition()` / `.any()` / `.find()` / `.filter(..).count()` (and `str::bytes()` versions) | one `ldrb; cmp; b.eq` per byte — the early exit stops LLVM from vectorizing or even unrolling | 4.5 GB/s | | `s.split(\|b\| *b == x)` / `rsplit` | same byte-at-a-time predicate loop per field | 4.5 GB/s | | `<[u8]>::contains(&x)`, `str::contains(char)`, `str::find(char)` | libcore's internal `memchr`: a 2×`usize`-per-iteration SWAR loop in scalar registers, no NEON/SSE | 48 GB/s | | `slice::windows(n).position(\|w\| w == needle)` | O(n·m) `memcmp` at every offset (std has no substring search for `[u8]` at all) | 0.75 GB/s | | `str::find(&str)` / `str::contains(&str)` | Two-Way searcher; the `simd_contains` fast path is compile-time gated on SSE2/NEON, so with our `-Ctarget-cpu=nehalem` x64 build it never uses AVX2 | ~40 GB/s (needle ≤ 32 B) | | `str::split*/lines/split_once/rsplit_once/matches` | per-field `CharSearcher` over the same internal SWAR `memchr` | — | | `memchr::*`, `bstr::ByteSlice::{find,rfind,find_byte,…}` | a second, separately-dispatched SIMD implementation (the `memchr` crate) instead of the one highway path | — | | `libc::memrchr` (old `last_index_of_char` on Linux) | fine on glibc, a plain byte loop on musl; scalar `rposition()` on macOS/Windows | — | | `WTF::reverseFind` (old `Buffer.lastIndexOf(byte)`) | one 16-byte vector per mask→scalar transfer | 58 GB/s (now 72) | `==`, `starts_with`, `ends_with`, `strip_prefix/suffix` lower to `memcmp` and are left alone. - `clippy.toml` denies `str::{find,contains,split*,…}`, `slice::windows`, `memchr::*`, `bstr::ByteSlice` search; the `memchr` crate is dropped. `test/internal/source-lints/byte-search.test.ts` catches the element-generic forms clippy can't type-filter (byte-literal `.contains(&b'x')`, `iter().position/rposition/any(..)`, `.split(|b| ..)`). - New kernels: `LastIndexOfChar`, `LastIndexOfAnyChar`, `IndexOfNotChar`, `CountChar`; `memrmem`'s 1-byte path uses `LastIndexOfChar`. `Buffer.indexOf/lastIndexOf/includes(byte)` use them instead of `WTF::find/reverseFind`. - `strings::last_index_of_char/last_index_of/count_char/index_of_not_char` are highway on every platform (were glibc `memrchr` / bstr / scalar); new `last_index_of_any`, `contains_any`, `count`, `split_any`, `rsplit`, `tokenize{,_any}`, `split_once*`, `SplitIterator: Iterator`. - ~250 call sites converted mechanically; no behaviour change intended, with one exception taken from review: a JSX tag name containing `-` or `:` is now a string tag regardless of case (`` → `jsx("Foo-Bar")`, matching esbuild — previously the check looked for the substring `"-:"` and emitted `jsx(Foo-Bar, …)`).

(Bare `bun -e 0` is ~0.35 ms slower for *any* PR artifact than for canary because PR lanes link without the startup order file — `orderFileEligible()` excludes pull requests; a same-toolchain local A/B against the merge-base shows no startup delta.) **Regression found and fixed along the way**: the first cut made `path.*.normalize/join/resolve/relative` ~0.4 ns per input byte slower (e.g. `normalize` of a 700-byte path 470 → 690 ns) even with no `..` in the input — inlining the FFI-reaching `last_index_of_char` into `normalize_string_t`'s cold `..` branch perturbed codegen of its per-byte loop. Fixed by handling sub-16-byte haystacks inline in the `bun_highway` wrappers (below one vector every kernel is scalar anyway) and moving the `..` pop out of line; numbers above are after that fix. ### How did you verify your code works? - New `test/js/bun/util/highway-strings.test.ts` sweeps each kernel over lane-boundary lengths × misaligned bases against a scalar reference (through a `bun:internal-for-testing` hook, since `Buffer.indexOf` is itself served by these kernels); `Buffer.indexOf/lastIndexOf/includes` asserted against planted positions incl. `byteOffset` variants. - Existing suites on the debug build: node `path` (ours + the vendored `test-path-*.js`), Buffer, which, password (plus new `m=+…` / unparseable-cost cases for the argon2 ceiling check), cron, ini, css, env, glob, workspaces, websocket, proxy, fetch, udp, transpiler (plus a new dashed/namespaced JSX tag test), `bun pm pkg`. - `cargo check` for windows / linux-gnu / linux-musl / freebsd / android; clippy + the new source lint clean; `verify-baseline-static` run locally against the CI linux-x64 profile artifact after allowlisting the new dispatch variants (0 violations). - Benchmarks as above; x64 not measured locally. --- Cargo.lock | 4 +- Cargo.toml | 1 - clippy.toml | 48 +++ .../allowlist-aarch64.txt | 18 +- .../allowlist-x64-windows.txt | 26 +- .../verify-baseline-static/allowlist-x64.txt | 26 +- src/CLAUDE.md | 21 +- src/base64/lib.rs | 2 +- src/bun_core/fmt.rs | 4 +- src/bun_core/ip_address.rs | 2 +- src/bun_core/lib.rs | 20 +- src/bun_core/string/immutable.rs | 375 ++++++++++++------ src/bun_core/util.rs | 10 +- src/bundler/HTMLScanner.rs | 3 +- src/bundler/defines.rs | 4 +- src/cares_sys/c_ares.rs | 2 +- src/clap/streaming.rs | 10 +- src/css/printer.rs | 18 +- src/css/properties/font.rs | 2 +- src/css/targets.rs | 4 +- src/dotenv/env_loader.rs | 8 +- src/glob/lib.rs | 14 +- src/highway/lib.rs | 211 +++++++++- src/http/h2_client/dispatch.rs | 2 +- src/http/h3_client/AltSvc.rs | 6 +- src/http/lib.rs | 8 +- .../WebSocketUpgradeClient.rs | 6 +- src/http_types/MimeType.rs | 4 +- src/http_types/URLPath.rs | 2 +- src/ini/lib.rs | 13 +- src/install/NetworkTask.rs | 4 +- src/install/PackageInstaller.rs | 9 +- src/install/TarballStream.rs | 3 +- src/install/bin.rs | 16 +- src/install/build.rs | 4 + src/install/dependency.rs | 8 +- src/install/hosted_git_info.rs | 8 +- src/install/lockfile.rs | 8 +- src/io/ParentDeathWatchdog.rs | 10 +- src/js/internal-for-testing.ts | 18 + src/js_parser/lib.rs | 4 +- src/js_parser/parser.rs | 4 +- src/jsc/bindings/JSBuffer.cpp | 21 +- src/jsc/bindings/highway_strings.cpp | 159 +++++++- src/jsc/bindings/highway_strings_testing.cpp | 96 +++++ src/jsc/bindings/highway_strings_testing.h | 14 + src/jsc/btjs.rs | 8 +- src/jsc/resolver_jsc.rs | 4 +- src/libarchive/lib.rs | 8 +- src/lsquic_sys/Cargo.toml | 3 + src/lsquic_sys/lib.rs | 6 +- src/md/ansi_renderer.rs | 4 +- src/options_types/jsx.rs | 4 +- src/parsers/json.rs | 2 +- src/parsers/json_stage2.rs | 15 +- src/parsers/native_test_shims.rs | 96 +++++ src/patch/lib.rs | 12 +- src/paths/lib.rs | 18 +- src/paths/resolve_path.rs | 21 +- src/ptr/ref_count.rs | 5 +- src/react_compiler/lowering/build_hir/expr.rs | 2 +- src/react_compiler/lowering/build_hir/jsx.rs | 4 +- .../optimization/optimize_for_ssr.rs | 2 +- src/react_compiler/program.rs | 53 +-- src/resolver/lib.rs | 2 +- src/resolver/node_fallbacks.rs | 6 +- src/resolver/package_json.rs | 8 +- src/resolver/tsconfig_json.rs | 4 +- src/router/lib.rs | 6 +- src/runtime/api/Archive.rs | 6 +- src/runtime/api/bun/h2_frame_parser.rs | 5 +- src/runtime/api/bun/js_bun_spawn_bindings.rs | 5 +- src/runtime/api/cron.rs | 7 +- src/runtime/api/cron_parser.rs | 8 +- src/runtime/bake/DevServer.rs | 2 +- src/runtime/bake/FrameworkRouter.rs | 11 +- src/runtime/bake/bake_body.rs | 2 +- .../bake/dev_server/source_map_store.rs | 2 +- src/runtime/cli/bunx_command.rs | 13 +- src/runtime/cli/create_command.rs | 4 +- src/runtime/cli/init_command.rs | 5 +- .../cli/install_completions_command.rs | 14 +- src/runtime/cli/mod.rs | 4 +- src/runtime/cli/multi_run.rs | 6 +- src/runtime/cli/pack_command.rs | 8 +- src/runtime/cli/pm_pkg_command.rs | 6 +- src/runtime/cli/pm_version_command.rs | 4 +- src/runtime/cli/repl.rs | 2 +- src/runtime/cli/run_command.rs | 11 +- src/runtime/cli/test/ChangedFilesFilter.rs | 13 +- src/runtime/cli/test/parallel/aggregate.rs | 4 +- src/runtime/cli/update_interactive_command.rs | 5 +- src/runtime/cli/why_command.rs | 10 +- src/runtime/crypto/pwhash.rs | 74 ++-- src/runtime/dns_jsc/dns.rs | 2 +- src/runtime/ffi/ffi_body.rs | 4 +- src/runtime/image/codecs.rs | 2 +- src/runtime/node/dir_iterator.rs | 2 +- src/runtime/node/memory_pressure.rs | 2 +- src/runtime/node/node_os.rs | 10 +- src/runtime/node/node_process.rs | 5 +- src/runtime/node/path.rs | 57 +-- src/runtime/node/quic/endpoint.rs | 2 +- src/runtime/node/quic/tls.rs | 2 +- src/runtime/server/DirectoryRoute.rs | 2 +- src/runtime/server/RequestContext.rs | 11 +- src/runtime/server/server_body.rs | 4 +- src/runtime/shell/builtin/export.rs | 2 +- src/runtime/shell/builtin/rm.rs | 6 +- src/runtime/socket/Handlers.rs | 2 +- src/runtime/socket/SocketAddress.rs | 6 +- src/runtime/socket/udp_socket.rs | 4 +- src/runtime/test_runner/diff/printDiff.rs | 4 +- src/runtime/test_runner/expect.rs | 13 +- .../test_runner/expect/toIncludeRepeated.rs | 3 +- src/runtime/test_runner/snapshot.rs | 12 +- src/runtime/webcore/Blob.rs | 13 +- src/runtime/webview/ChromeProcess.rs | 2 +- src/s3_signing/credentials.rs | 2 +- src/sourcemap/lib.rs | 13 +- src/spawn/lib.rs | 4 +- src/sql/postgres/protocol/NewReader.rs | 2 +- src/sql_jsc/postgres/PostgresSQLConnection.rs | 2 +- src/sys/Cargo.toml | 3 -

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #37044 ## Repro ```ts import { Database } from 'bun:sqlite'; const db = new Database(':memory:'); db.exec('CREATE VIRTUAL TABLE notes_fts USING fts5(body)'); db.query("SELECT rowid FROM notes_fts WHERE notes_fts MATCH 'hello'").all(); db.close(); // panic(main thread): Segmentation fault at address 0x28 ``` Crashes in `sqlite3Fts5IndexClose` / `fts5DisconnectMethod` under `sqlite3_close`. Reproduces on Linux and macOS; ASAN reports a heap-use-after-free with `sqlite3_finalize` (from `jsSQLStatementCloseStatementFunction`) as the free site and `sqlite3Fts5IndexClose` as the read. ## Cause Regression from #36573. `close()` sweeps every prepared statement on the connection via `sqlite3_next_stmt()` and finalizes the ones bun isn't keeping. Virtual-table modules like FTS5 cache their own internal prepared statements and finalize them themselves during vtab disconnect inside `sqlite3_close*`, so the sweep finalized them first and the disconnect then called `sqlite3_finalize` on dangling pointers. This also matches the reporter's observations: `DROP TABLE` before `close()` avoids it (teardown goes through xDestroy while the statements are still valid), as does never calling `close()`. Since #36573, every bun-created statement wrapper is tracked in `VersionSqlite3::statements`, so the sweep's only remaining job was the transient statement in `db.run()` when a bound-parameter getter re-entrantly closes the database mid-bind. ## Fix Only finalize the statements bun tracks. If untracked statements still make `sqlite3_close()` return `SQLITE_BUSY` (the re-entrant `db.run()` case), retire the handle with `sqlite3_close_v2()`, which defers the close until the owner finalizes them, instead of finalizing other code's statements behind its back. The `db.run()` path now lets its transient statement be finalized by its scoped owner, which completes the deferred close. ## Verification New test fails on the unfixed build (segfault) and passes with the fix. `bun bd test test/js/bun/sqlite/sqlite.test.js` 114 pass (including the #36573/#36793 close semantics tests), `test/js/node/sqlite/` 115 pass, `test/regression/issue/14709.test.ts` 5 pass. The reporter's 500-iteration loop prints `survived` under the ASAN debug build. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Anything pager-, REPL-driver-, or expect-style that toggles raw mode while the child is printing can hit this. ### Cause `Terminal.setRawMode` routed through the libuv-derived `ttySetMode` in `wtf-bindings.cpp`, which applies termios with `tcsetattr(fd, TCSADRAIN)`. Kernel stacks show the deadlock directly: bun's JS thread sits in `ioctl -> tty_ioctl -> set_termios -> tty_write_lock`, the child sits in `write -> n_tty_write -> wait_woken`. On Linux a termios ioctl on the PTY master applies to the slave, and `TCSADRAIN` takes the slave's write lock. A child blocked mid-`write()` on a full PTY holds that lock until someone reads the master, and the only reader of the master is the thread stuck inside `tcsetattr`. Two-party deadlock. `TCSADRAIN`'s "wait for output to drain first" is meaningful on a real tty, but on a PTY master the drain can only ever be performed by the caller itself, so it can never be satisfied by waiting. The other `Terminal` termios setters (`inputFlags` etc., `resize`) already use `TCSANOW`/`TIOCSWINSZ` and are unaffected. ### Fix `ttySetMode` now takes the `tcsetattr` action as a parameter. `Bun.Terminal.setRawMode` passes `TCSANOW`, consistent with the other `Terminal` termios setters. Real ttys keep `TCSADRAIN`, matching libuv: `process.stdin.setRawMode` (node:tty), the repl, and the interactive CLI prompts are unchanged. ### Verification - New test in `test/js/bun/terminal/terminal.test.ts` ("does not deadlock while the child is blocked writing to a full PTY"). It fails on the unfixed build in ~10s via a watchdog and passes in ~1.3s with the fix. The watchdog kills the PTY child's process group before killing the spawned bun, because in the broken state SIGKILL alone cannot reap the process (the kernel retries the blocked ioctl with the signal pending until the PTY child dies), so a failing run cannot leave a spinning process behind in CI. - The interval-toggle variant (child streaming 5MB through `od` while flipping `setRawMode` every 50ms) also runs to completion with the fix. - Full `test/js/bun/terminal/` suite passes (133 pass, 1 windows-only skip). --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Several socket dispatch sites could leave the VM in exactly that state: they call a fallible operation whose `Err` means "a JS exception is pending", discard the `Err`, and return to the uSockets/libuv event loop. The next native JSC call in the same tick then runs with the stale exception. In debug/ASAN builds that trips the assert (`JSObject::get`, or `assertNoExceptionExceptTermination` at the microtask-drain entry); in release the exception gets attributed to whatever runs next. The sites, all in `src/runtime/socket/`: - `handle_connect_error` swallowed a failed promise reject with `handlers.reject_promise(err_val).unwrap_or(true)` and returned `Ok` with the exception still set (a `// TODO: properly propagate exception upwards` site), and its other two settle sites (`reject`, `reject_as_handled`) returned `Err` into callers that all discarded it: `connect()`'s synchronous `do_connect()` failure branch, the `on_connect_error` event-loop dispatch, the Windows named-pipe `on_error`/`fail_and_release`, and the duplex TLS upgrade teardown. - `on_open` swallowed a failed resolve of the connect promise (the other `// TODO: properly propagate exception upwards` site) and returned to the loop with the exception pending, and did the same `unwrap_or(true)` swallow when rejecting with an error returned from the `open` callback. - `us_dispatch_session` / `us_dispatch_keylog` (and the duplex and named-pipe equivalents) discarded `on_session` / `on_keylog` results; those return `Err` when allocating the session/keylog `Buffer` throws. ### Fix The pending exception has to be handled at the failure site, before the dispatch's scope guards drop: `ScopeExit` runs a microtask checkpoint on scope exit, and entering that checkpoint with a non-termination exception pending is itself the asserted condition, so an `Err` propagated or discarded past the guard is already too late. And the event-loop dispatch callers have no JS frame to propagate into in the first place. So each failed settle now reports its exception as unhandled right where it fails, via `report_active_exception_as_unhandled`: the same idiom the socket error handler, ipc, h2, fs-watcher, and dns (#37004) completions use. That clears and reports a real throw, and leaves a termination exception pending, which is what the event loop expects (`assertNoExceptionExceptTermination`). With every failure handled internally, `handle_connect_error`, `on_session`, and `on_keylog` become infallible, and `on_handshake`/`on_close` (whose `Err` paths were structurally dead: `verify_error_to_js` cannot fail) are made infallible with them, so no dispatch call site can discard an `Err` from this family again; every `let _ =` at those call sites is gone. ### Verification The promise-settle failures (`JSPromise::resolve/reject`) only occur on JSC heap OOM or termination mid-call, so those arms have no deterministic reproduction; they are covered by the behavior-level tests below plus the analysis above. The session/keylog `Buffer` allocation has the same trigger, but for that one this PR adds a `session_buffer` fault-injection rule (mirroring the existing `ssl_loop_buffer` rule for the one other allocation whose failure is unreachable without injection), which makes the fix deterministically testable: - `socket-session-oom-fixture.ts` arms the rule, completes a TLS handshake with a `session` handler, and asserts the injected allocation failure surfaces as an `uncaughtException` while the event loop survives (a TCP round trip completes afterwards and the process exits 0). With the hook but without the fix, the same fixture dies on `ASSERTION FAILED: ... !exception() || m_vm.hasPendingTerminationException()` in `ExceptionScope::assertNoExceptionExceptTermination`, the fuzzer's failure class. - New behavior tests cover every touched dispatch path: TLS `session`/`keylog` delivery (previously untested), throws from `session`/`keylog`/`open` handlers reaching the socket's (or listener's) `error` handler while `connect()` still resolves, a synchronous unix connect failure rejecting with `ENOENT` (run in a child with a relative socket path so macOS's 104-byte `sun_path` limit cannot clobber the errno), and a throw from `connectError` becoming the `connect()` rejection. - The Windows named-pipe paths were exercised directly (named-pipe client lifecycle tests, including the failed-connect branch this PR touches, and the Windows connect error-code tests): all pass on a Windows debug build. - The existing fault-injection suites (`socket-syscall-fault`, `tls-syscall-fault`) pass with the new rule added. - `test/js/bun/net/`, `test/js/node/net/`, and the node-tls connect suites show the identical failure set as a baseline build in this sandboxed environment (local DNS/IPv6 limitations), with no new failures. `cargo check` passes on all 10 platform targets. Related but distinct open work: #36808 gates these dispatch sites against an already-pending termination (entry-side), while this PR fixes exceptions the dispatch itself creates (exit-side); #35221 changes which errno the DNS-path `connectError` reports, not the exception discipline. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

Internal entities are expanded (with expat-style amplification/depth limits, so billion-laughs throws), attribute values are normalized and internal-subset defaults applied, and UTF-8 / UTF-16 / ISO-8859-1 input is decoded per §4.3.3. - `parse` returns the compact object by default (`"@attr"`, `"#text"`, arrays for repeated names, values always strings); `{ compact: false }` returns the ordered `{ name, attributes, children }` tree. `stringify` accepts either, with `JSON.stringify`-style `space`. - `xml-test-suite.test.ts` is generated from the W3C conformance suite (xmlts20130923): 927 must-reject, 752 must-accept (262 checked against canonical output), 316 processor-class-dependent cases pinned with the upstream verdict noted. - Behavior change, same as when `.yaml`/`.json5` landed: `.xml` now has a default loader, so importing one yields the parsed object rather than a `file`-loader path; `--loader .xml:file` restores that. - `src/api/schema.js` gains the `json5`/`md`/`xml` loader entries it lacked, so `Bun.build` plugins can see and return them. ### How did you verify your code works? `bun bd test` on `test/js/bun/xml/` (1995 + 54 pass), `resolve/xml`, `require.test.ts`, `bundler_loader`, `bundler_plugin -t Xml`, `transpiler-unsupported-loader`, and the bun-types test; the new tests fail under `USE_SYSTEM_BUN=1`. `bun run rust:check-all` is clean. `bench/xml` (release, M4 Max): parse is ~5× fast-xml-parser / xml2js on ~200 KB feeds and on par for tiny documents. --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- .gitattributes | 7 + bench/xml/bun.lock | 36 + bench/xml/package.json | 8 + bench/xml/xml.mjs | 100 + docs/bundler/loaders.mdx | 53 + docs/docs.json | 2 + docs/guides/runtime/import-xml.mdx | 63 + docs/runtime/bun-apis.mdx | 2 +- docs/runtime/file-types.mdx | 53 +- docs/runtime/xml.mdx | 247 + .../bundler_plugin.h | 3 +- packages/bun-types/bun.d.ts | 139 + packages/bun-types/extensions.d.ts | 5 + scripts/build/codegen.ts | 5 +- src/analytics/lib.rs | 1 + src/api/schema.d.ts | 9 + src/api/schema.js | 12 + src/ast/loader.rs | 8 +- src/bun_core/Global.rs | 7 +- src/bundler/LinkerContext.rs | 1 + src/bundler/ParseTask.rs | 29 + src/bundler/options.rs | 13 +- src/bundler/transpiler.rs | 16 +- src/bundler_jsc/options_jsc.rs | 2 +- src/js_printer/lib.rs | 4 + src/jsc/bindings/BunObject+exports.h | 1 + src/jsc/bindings/BunObject.cpp | 1 + src/jsc/bindings/ModuleLoader.cpp | 4 +- src/jsc/bindings/headers-handwritten.h | 3 +- src/options_types/bundle_enums.rs | 3 + src/options_types/schema.rs | 2 + src/parsers/lib.rs | 3 + src/parsers/xml.rs | 3096 +++ src/runtime/api.rs | 3 + src/runtime/api/BunObject.rs | 7 +- src/runtime/api/XMLObject.rs | 809 + src/runtime/cli/test/parallel/runner.rs | 1 + src/runtime/jsc_hooks.rs | 11 +- test/bundler/bundler_loader.test.ts | 71 + test/bundler/bundler_plugin.test.ts | 26 + test/integration/bun-types/fixture/xml.ts | 24 + test/js/bun/resolve/fixtures/require/obj.xml | 3 + test/js/bun/resolve/require.test.ts | 19 +- test/js/bun/resolve/xml/xml-empty.xml | 0 test/js/bun/resolve/xml/xml-fixture.xml | 10 + test/js/bun/resolve/xml/xml-fixture.xml.txt | 1 + test/js/bun/resolve/xml/xml-latin1.xml | 1 + test/js/bun/resolve/xml/xml-malformed.xml | 4 + test/js/bun/resolve/xml/xml-utf16be-bom.xml | Bin 0 -> 150 bytes test/js/bun/resolve/xml/xml-utf16le-bom.xml | Bin 0 -> 150 bytes test/js/bun/resolve/xml/xml-utf8-bom.xml | 1 + test/js/bun/resolve/xml/xml.test.js | 90 + .../transpiler-unsupported-loader.test.ts | 9 +- test/js/bun/xml/generate_xml_test_suite.ts | 648 + test/js/bun/xml/xml-test-suite.test.ts | 16815 ++++++++++++++++ test/js/bun/xml/xml.test.ts | 853 + 56 files changed, 23316 insertions(+), 28 deletions(-) create mode 100644 bench/xml/bun.lock create mode 100644 bench/xml/package.json create mode 100644 bench/xml/xml.mjs create mode 100644 docs/guides/runtime/import-xml.mdx create mode 100644 docs/runtime/xml.mdx create mode 100644 src/parsers/xml.rs create mode 100644 src/runtime/api/XMLObject.rs create mode 100644 test/integration/bun-types/fixture/xml.ts create mode 100644 test/js/bun/resolve/fixtures/require/obj.xml create mode 100644 test/js/bun/resolve/xml/xml-empty.xml create mode 100644 test/js/bun/resolve/xml/xml-fixture.xml create mode 100644 test/js/bun/resolve/xml/xml-fixture.xml.txt create mode 100644 test/js/bun/resolve/xml/xml-latin1.xml create mode 100644 test/js/bun/resolve/xml/xml-malformed.xml create mode 100644 test/js/bun/resolve/xml/xml-utf16be-bom.xml create mode 100644 test/js/bun/resolve/xml/xml-utf16le-bom.xml create mode 100644 test/js/bun/resolve/xml/xml-utf8-bom.xml create mode 100644 test/js/bun/resolve/xml/xml.test.js create mode 100644 test/js/bun/xml/generate_xml_test_suite.ts create mode 100644 test/js/bun/xml/xml-test-suite.test.ts create mode 100644 test/js/bun/xml/xml.test.ts diff --git a/.gitattributes b/.gitattributes index 94af433ee123..0362972a38dc 100644 --- a/.gitattributes +++ b/.gitattributes @@ -24,6 +24,13 @@ *.lockb binary diff=lockb +# XML loader fixtures in specific byte encodings (BOMs, UTF-16, ISO-8859-1);

Both workflows only run on pull_request, which is how the drift landed unnoticed. ## Clippy (2 errors) - `src/parsers/yaml.rs`: `bind_anchor` takes `PendingAnchor` by value on purpose, so that binding consumes the `#[must_use]` anchor token (landed via #37055, trips `-D clippy::needless-pass-by-value`). Added a targeted `#[allow]` with a one-line reason, matching existing usage elsewhere in the tree. - `src/runtime/socket/uws_handlers.rs`: #37067 changed `NewSocket::on_close` / `on_handshake` to return `()`, leaving two `swallow(...)` wrappers passing a unit value (`-D clippy::unit-arg`). Call them directly, matching the neighboring handlers in the same impl. `cargo clippy --workspace --no-deps` now exits 0. ## rustfmt (4 files) `src/bun_core/tty.rs`, `src/md/ansi_renderer.rs`, `src/runtime/bake/bake_body.rs`, `src/runtime/server/server_body.rs` had unformatted hunks. Ran `cargo fmt --all`; `cargo fmt --all --check` now exits 0. ## tsconfig - Root `tsconfig.json` still referenced `./src/bake`, which moved to `./src/runtime/bake` in the Rust rewrite, so `tsc --noEmit` failed immediately with TS6053. Updated the project reference. - `test/tsconfig.json` now excludes the three `test/regression/issue/14477/*-mismatch.tsx` fixtures: they contain deliberately mismatched JSX closing tags (the test asserts the parse error), which are unsuppressable TS17002 syntax errors. Note: `cd test && tsc --noEmit` still reports several thousand pre-existing semantic errors across the test suite; that is long-standing drift (not CI-enforced) and out of scope here. Also verified green on this branch: oxlint, clang-format check, prettier. ## Miri `cargo miri test` is also red on every PR: #37052 routed all byte search through the highway C++ kernels, and Miri cannot call foreign functions. The first caller to hit it is `bun_ptr::ref_count::type_base_name` (`strings::last_index_of` -> `highway_memrmem`). Under `cfg(miri)` the search wrappers in `src/highway/lib.rs` now take their scalar paths: the char and char-set scans reuse their existing short-input scalar prologue at every length, and the `mem*mem` wrappers get a scalar substring search. Kernels with no scalar form (hashing, hex, sourcemaps, lexer scans) stay FFI-only so a Miri-tested crate reaching one still fails loudly. Verified locally: `bun run rust:miri` green on bun_ptr (previously failing), bun_ast, bun_base64, bun_clap, bun_collections, bun_dispatch, bun_errno, and bun_hash; this PR's Miri workflow runs the full set. ## Verification The changes have no runtime-observable behavior: the proof is this PR's own Clippy and Format CI checks, which run `cargo clippy --workspace` and `cargo fmt --all --check` (both red on main, both green here), plus `tsc --noEmit` resolving again at the repo root. An earlier revision added a source-lint test walking the tsconfig reference graph; it was removed per maintainer feedback. --- src/bun_core/tty.rs | 4 +- src/highway/lib.rs | 170 +++++++++++++++++++---------- src/md/ansi_renderer.rs | 6 +- src/parsers/yaml.rs | 2 + src/runtime/bake/bake_body.rs | 2 +- src/runtime/server/server_body.rs | 5 +- src/runtime/socket/uws_handlers.rs | 9 +- test/tsconfig.json | 3 +- tsconfig.json | 2 +- 9 files changed, 134 insertions(+), 69 deletions(-) diff --git a/src/bun_core/tty.rs b/src/bun_core/tty.rs index 29926732e65a..4bf156f91360 100644 --- a/src/bun_core/tty.rs +++ b/src/bun_core/tty.rs @@ -89,7 +89,9 @@ impl RawModeGuard { impl Drop for RawModeGuard { #[inline] fn drop(&mut self) { - let _ = self.state.set_mode(self.fd, Mode::Normal, SetAttrWhen::Drain); + let _ = self + .state + .set_mode(self.fd, Mode::Normal, SetAttrWhen::Drain); } } diff --git a/src/highway/lib.rs b/src/highway/lib.rs index fa4a35fc2d95..fb2ca825210c 100644 --- a/src/highway/lib.rs +++ b/src/highway/lib.rs @@ -10,6 +10,7 @@ unsafe extern "C" { fn highway_count_char(haystack: *const u8, haystack_len: usize, needle: u8) -> usize; + #[cfg(not(miri))] fn highway_memmem( haystack: *const u8, haystack_len: usize, @@ -19,6 +20,7 @@ unsafe extern "C" { // These three return `usize::MAX` for not-found (the empty needle matches at // 0 / `haystack_len` respectively). + #[cfg(not(miri))] fn highway_memrmem( haystack: *const u8, haystack_len: usize, @@ -26,6 +28,7 @@ unsafe extern "C" { needle_len: usize, ) -> usize; + #[cfg(not(miri))] fn highway_memmem16( haystack: *const u16, haystack_len: usize, @@ -33,6 +36,7 @@ unsafe extern "C" { needle_len: usize, ) -> usize; + #[cfg(not(miri))] fn highway_memrmem16( haystack: *const u16, haystack_len: usize, @@ -157,6 +161,31 @@ unsafe extern "C" { /// call into a caller's hot loop (see `pop_last_segment_t` in node/path.rs). const SCALAR_CUTOFF: usize = 16; +/// Miri cannot call foreign functions, and the workspace denies std's search +/// methods everywhere else, so under Miri (`bun run rust:miri`) the search +/// wrappers below take their scalar path at every length.

The same crash happens through `build.onLoad` returning a `loader: "object"` result, and through `require()` of the virtual module (there the fault address is the `getIfPropertyExists` call on the null object). UBSan on a debug build reports `src/jsc/modules/ObjectModule.cpp:20:17: runtime error: member call on null pointer of type 'JSC::JSCell'`. ## Cause `handleOnLoadObjectResult` in `src/jsc/bindings/ModuleLoader.cpp` sets `result.type = OnLoadResultTypeObject` before reading the `exports` property off the plugin's result object. When that property read throws (a user-defined getter, or a Proxy trap), the exception branch stored the exception in `result.value.error` but returned with the type still `OnLoadResultTypeObject`. `handleVirtualModuleResult` then took the Object case, `value.object.getObject()` on the stored exception cell returned nullptr, and the null object was dereferenced: immediately via `getIfPropertyExists` on the `require()` path, or inside `generateObjectModuleSourceCode`'s source generator on the `import()` path. ## Fix Set `result.type = OnLoadResultTypeError` in the exception branch, matching every other error path in the function. The import now rejects (and `require()` throws) with the getter's error. ## Verification ``` USE_SYSTEM_BUN=1 bun test test/js/bun/plugin/plugins.test.ts -t "throwing exports getter" -> 3 fail (child process segfaults) bun bd test test/js/bun/plugin/plugins.test.ts -> 38 pass, 0 fail ``` New tests cover all three faces: `build.module` + `import()`, `build.module` + `require()`, and `build.onLoad` + `import()`. Each spawns a subprocess and asserts the process exits 0 after printing the getter's error message. --- **[review]** gate passed · iteration 0 · 2 files touched

On Linux, mimalloc (built with `MI_DEFAULT_ALLOW_THP=0`) kept its arenas off transparent huge pages by calling `prctl(PR_SET_THP_DISABLE)` at startup. That flag is process-wide, inherited across `fork` and preserved across `execve`, so every process bun has spawned since April 2024 — `Bun.spawn`, `bun run`, lifecycle scripts — ran with THP disabled, including its own explicit `MADV_HUGEPAGE` requests: ``` $ bun -e 'console.log(Bun.spawnSync(["grep","THP_enabled","/proc/self/status"]).stdout+"")' THP_enabled: 0 ``` This bumps mimalloc to oven-sh/mimalloc#12 (merged), which opts out per mapping (`MADV_NOHUGEPAGE`, a VMA flag dropped at `execve`) instead, and does the same for `bun_alloc`'s lazily-faulted 4 MB arena, which the process-wide flag had covered incidentally. JSC's own reservations get the same treatment in oven-sh/WebKit#388 (merged; `WEBKIT_VERSION` bumped to its main autobuild `ddea71318fec`). Unlike #35691 there is no per-spawn work and no vfork shared-mm restore. RSS on a THP `enabled=[always]` host (x64 release; `madvise` hosts are unaffected either way): | | `bun -e 1` peak | `Bun.serve` hello | child `THP_enabled` | |---|---|---|---| | main (prctl) | 30.2 MB | 46.5 MB | **0** | | mimalloc#12 + bun_alloc only | 33.9 MB | 49.6 MB | 1 | | this branch | 30.3 MB | 46.6 MB | 1 | | THP fully allowed | 54.5 MB | 68 MB | 1 | The 3 MB between rows 2 and 3 is entirely `[anon:JSStructureHeap]`. ### How did you verify your code works? New case in `test/js/bun/spawn/spawn.test.ts` (gated on the parent's `THP_enabled` being 1; the spawned child must report 1 too): fails against a main build (`Received: "0"`), passes on this branch, on an Arch box with THP `[always]`.

The `isBuiltinModule()` predicate itself still recognizes it, so `Bun.plugin` keeps rejecting attempts to override it. - **Error formatting**: quoted strings in `ERR_*` messages escape control characters the way util.inspect does (`\x00`, `\n`, …), and object values render on one line (`Received { abc: 123 }`) via the same single-line inspector `Buffer` error messages use. ### Removed - `test/js/node/test/parallel/test-process-execve-abort.js`: it asserted Bun's pre-Node-26 `process.execve` failure behavior (print `process.execve failed with error code …` to stderr, then abort). Node ≥ 26 throws instead and Node v26.3.0's own suite replaces it with `test-process-execve-throws.js`, which is vendored here and passes. ### Known limitations / follow-ups - `process.getActiveResourcesInfo()`, `_getActiveHandles()` and `_getActiveRequests()` remain stubs that return `[]`. A counter-based implementation was explored and backed out in this PR; doing it properly needs a live handle registry and belongs in its own change. The six upstream `test-process-getactiveresources-*` tests are accordingly not vendored. - `test-process-exec-argv` needs Worker stdio piping (`new Worker(..., { stdout: true })`); not vendored. - Unportable upstream tests (not vendored): `test-process-binding*` (`internalBinding`), `env-allowed-flags-are-documented` (reads Node's docs tree), `setflagsfromstring` (V8 flags), `execve-permission-fail` + the `--permission` subtest of `load-env-file` (Node permission model), `env-sideeffects` (inspector `throwOnSideEffect`), `versions` (reads Node's deps tree). - The default warning printer is now a real `'warning'` listener (a port of node's `onWarning`), but it is installed lazily on the first `process.emitWarning()` rather than at startup, to keep the cost off the common path. Two consequences differ from node: `process.removeAllListeners('warning')` before any warning is emitted does not silence the default print (`--no-warnings` does), and a bare `process.emit('warning', w)` with no prior `emitWarning()` prints nothing. The second of these also behaves this way on main, i.e. it is not a regression. A callable replacement assigned to `process._fatalException` is recognized but not invoked as the fatal handler (only its non-callability is honored, with exit code 6). - On Windows, `process.env` inside a worker spawned with `new Worker(file, { env: {...} })` is a plain object (not wrapped in the `windowsEnv` Proxy), so writes there do not coerce to string or reject symbol keys / accessor descriptors. Same root as the next bullet: once Windows case-insensitivity moves into `JSEnvironmentVariableMap` both gaps close together. - `structuredClone(process.env)` throws `DataCloneError` on Windows, where `process.env` is a `Proxy` (for case-insensitive lookups) rather than the exotic object used on POSIX; the structured clone algorithm rejects proxies. That one block of the vendored `test-process-env.js` is skipped on Windows with the reason inline; the rest of the file runs there. The real fix is to move Windows case-insensitivity into `JSEnvironmentVariableMap` so both platforms share the exotic object and the proxy can be dropped. - SHARE_ENV workers' `process.env` (`JSSharedEnvMap`, added on main) now shares this PR's DEP0104 deprecation and its accessor-descriptor rejection, so it answers `Object.defineProperty` like the regular map and like node. It still accepts *partial* data descriptors that the regular map rejects; tightening that is a further behavior change to SHARE_ENV and needs its own tests. - Bun renders a base `Error` as `error:` and has no V8 `Object.` frame receivers; two stderr-format assertions are adapted in place with comments. ## Testing Validated locally with the debug build before pushing: - Full `test-process-*` parallel + sequential sweep with the runner's semantics (`bun run|test --config=bunfig.node-test.toml`): **83 pass, 0 fail**. - Bun's own `test/js/node/process/process.test.js` and `process-execve.test.ts`, plus regression sweeps over the touched surfaces (`string_decoder`, `events/event-emitter`, `buffer-inspectmaxbytes`): all pass. -

The pipe itself is owned by the `JSHTMLRewriterTransform` cell, whose finalizer frees the Box. When the rewrite is abandoned mid-stream (input never closes, output dropped), the Transform cell, the input stream, the pump, and the controller all become garbage in the same GC cycle, and JSC sweeps those cells in unspecified order. Transform cell first means the controller destructor then reads (and on the matching path writes) the freed pipe. The suspension hand-off had the same shape: a suspended transform abandoned with a JS-pump input could have the deferred `abandon_suspension` task free the pipe while the controller destructor still held the raw pointer, in either order. ### Fix `RewriterPipe` now tracks its owners in a small claim count: the Transform cell (from `init` until its finalizer), the JS-pump controller (from `assign_to_stream` until `__controllerDetached`, which fires exactly once on every detach path including the destructor), and a parked suspension's reaction or abandon task. Whoever releases the last claim frees the Box. A controller-origin release never frees inline because the releasing C++ frame keeps calling into the allocation after it returns (the destructor calls `__finalize` next; the close/end host fns call `__close`/`__endWithSink` on the saved pointer), so that case defers the free to an event-loop task, reusing the existing `DeferredDerefTask` used by the abandon path. `JsSinkType` gains a default no-op `controller_detached` hook so the generic `js_controller_detached` can notify the sink; behavior for every other sink type is unchanged. ### Verification - Unfixed debug ASAN build: repro aborts with the stack above, 3/3 runs; the new test fails the same way. - Fixed build: repro prints `done`, 5/5 runs; new test passes. - `test/js/workerd/html-rewriter-leak.test.ts` (includes the suspension/abandon lifetime tests), `html-rewriter.test.js`, `html-rewriter-end-error.test.ts`, `html-rewriter-doctype.test.ts`, `htmlrewriter-additional-bugs.test.ts`: all pass (154 tests). - `test/js/web/fetch/body-stream.test.ts` (9086) and `test/js/bun/util/filesink.test.ts` (57) pass, covering the shared sink-controller machinery. The new test is `skipIf(!isASAN)`: the stale read is only observable under ASAN. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

From 43caaf38f99338d7c85ad0651cd490d2ab3488ed Mon Sep 17 00:00:00 2001 From: Ciro Spaciari Date: Fri, 7 Aug 2026 13:35:00 -0700 Subject: [PATCH 177/304] node compat batch: callback-throw dispatch, Assert class + native deep-equality parity, Intl gate + URL/buffer fallout, compile cache, watch kill-signal, profilers (+98 tests) (#34660) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Batch of node-compat fixes that unblock each other, verified against the node v26.3.0 binary throughout. Adds 98 vendored upstream tests (parallel + sequential), all passing. ## Callback-throw dispatch (the original headline) A throw inside a node-style callback in `node:fs`, `node:dns` or `crypto.pbkdf2` surfaced as an unhandledRejection instead of an uncaughtException, because those callbacks dispatch from a promise reaction. `guardCallback` in `internal/shared.ts` routes the exception to the same native uncaught path timers already use, applied at the existing chokepoints (`ensureCallback` in fs, `validateResolve` in dns, pbkdf2). Happy-path timing is byte-identical to base, verified by diffing a full event-loop ordering trace. The throw reaches `uncaughtException` synchronously from the callback's own frame, matching node's measured semantics. ## Assert class + node-correct deep equality Node v26's `Assert` class (per-instance `diff`/`strict`/`skipPrototype`, `ERR_CONSTRUCT_CALL_REQUIRED`). Deep equality is confined by API ownership: the node entry points (`assert` strict variants, `util.isDeepStrictEqual`) compare prototypes and own-enumerable properties like node, while `Bun.deepEquals` and every `expect()` instantiation are verified behavior-identical to before. `assert.partialDeepStrictEqual`'s comparison engine is implemented natively in C++ (object/array/Map/Set subset semantics, Date/RegExp/boxed-primitive/DataView arms, cycle guards), pinned by a cumulative matrix run byte-identical against node. ## Intl gate fix + fallout, solved together `process.config.variables` spelled the key `v8_enable_i8n_support`, so every vendored test gated on `common.hasIntl` silently skipped its Intl half. This lands the typo fix with the fallout: `buffer.transcode` (simdutf fast paths), node's host-parse semantics for `domainToASCII/Unicode` including the Unicode 16 IDNA delta node ships via ada (Bun's ICU is older; the delta is applied at the node:url entry points, cited in `NodeURL.cpp`), `url.format`/`url.parse` host rules, TextDecoder fatal messages, `util.inspect` URL formatting. Two user-visible changes called out for review: `new URL(bad)` now throws node's exact `TypeError: Invalid URL` with `code`/`input`, and invalid-punycode `xn--` hosts are rejected for special schemes (matching node, Chrome, Firefox, and WPT). ## Also here - `module.enableCompileCache()` / `NODE_COMPILE_CACHE`: bytecode cache with atomic persist at exit (including the self-kill signal path), persist pass runs unlocked so Worker module loads never stall. - `--watch-kill-signal`: watch reloads deliver the configured signal to JS listeners before execve, on POSIX and Windows (real Windows signal numbers, not Linux discriminants). - `--cpu-prof` and `--heap-prof` write real V8-format profiles/snapshots with node's shared filename sequence. - async_hooks: AsyncResource lifecycle + tick/timer hooks behind the existing enable-gates (promise hooks need a WebKit-fork patch and are explicitly out of scope). - `bun -pe` alias, internal-module shims for vendored tests (`internal/*` interceptor merges native implementations over the vendored ports), `require.resolve` builtin handling and paths validation moved native, `isURL` and `stringWidth(perCodePoint)` native. ## Verification Interleaved same-commit sweeps with zero regressions across fs/dns/domain/pbkdf2 (356 vendored files), assert (361), url, util, expect (510), plus the bun-side suites for each subsystem. Deleted along the way rather than shipped red: `test-child-process-advanced-serialization.js` (passes vacuously on main via the runner's swallowed-rejection bug #34859; the real gap is #34860) and `test-whatwg-url-toascii.js` (WHATWG URL constructor goes through WebKit + system ICU, so distro data decides; returns with the ICU-bundling decision). --- **no test proof** · iteration 48 · Platform-specific test(s) that do not run on this machine.

charset=UTF-8 Content-Transfer-Encoding: 8bit ### Problem A V8-API addon using the stock nan idiom crashes deterministically (`Segmentation fault at address 0xC`, in ASAN builds a UBSan `member access within null pointer of type 'const Map'` at `v8::Data::localToJSValue` via `v8::shim::FunctionTemplate::invokeCallback`): ```cpp static void probe(const FunctionCallbackInfo& info) { Isolate* iso = info.GetIsolate(); HandleScope hs(iso); // nested scope inside the callback Local f = g_cb.Get(iso); (void)f; // Local::New(isolate, persistent) info.GetReturnValue().Set(String::NewFromUtf8(iso, "x").ToLocalChecked()); } ``` Node 26.3.0 prints the string; Bun segfaults when the callback returns. ### Cause V8's inline `ReturnValue::Set` copies the Local's Address into the callback frame's return-value slot. In real V8 that Address is the heap object itself, so it is legal for the returned local's handle scope to close before the callback returns: the scope owns only the slot, never the object. In the shim the Address points at a `Handle`'s `ObjectLayout` inside a `HandleScopeBuffer`. The `Global::Get` forces an `Extend` grant inside the nested scope, so the scope's inline destructor runs `DeleteExtensions` -> `deleteGrantsBack`, which destroys every handle created inside the scope, including the string the return slot points at. `invokeCallback` then reads the zeroed handle: its map is null, and loading `m_instanceType` (offset 12) crashes at 0xC. The same stranding happens through `PropertyCallbackInfo` accessors (`Template::SetNativeDataProperty`), and through Bun-internal scope pops while a callback frame is live (`Array::Iterate` pops its internal scope, killing an element local the callback returned). ### Fix `GlobalInternals` now tracks the return-value slots of the callback frames currently on the native stack (RAII registration in `FunctionTemplate::invokeCallback` and the accessor frame builder in `TemplateProperty.cpp`). Before `deleteGrantsBack` destroys condemned handles, and before a popping scope's buffer clears (`~HandleScope` -> `evacuateActiveReturnValues`), any condemned handle a live return slot points at is copied into surviving storage (same buffer after the sweep, or the enclosing scope's buffer on pop) and the slot is repointed at the copy. Heap numbers are copied as doubles; cells are re-created through the write-barriered `Handle` constructor so GC visitation is preserved. ### Verification - New `test/v8` cases cover all four shapes (string and heap number returned from an inner scope, element returned from inside `Array::Iterate`, accessor value via `SetNativeDataProperty`). All four crash unfixed bun and print node-identical output with the fix. - Standalone repro addon built against node 26.3.0 headers: crashed before, matches node after, ASAN/UBSan clean. - `bun bd test test/v8/v8.test.ts`: 74 pass, 0 fail (1 pre-existing ASAN skip). - With `src/` stashed, the new test fails; with the fix it passes. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem In [Buildkite build 89973](https://buildkite.com/bun/bun/builds/89973), both Windows test lanes (x64 and aarch64) printed, for one file of the parallel bucket: ``` ✗ test\js\node\zlib\zlib-estimated-size-gc.test.ts (worker crashed: exit code 9) ``` with zero per-test output under the file header. The file then passed 6/6 when retried alone, so the event was recorded as a flaky test and forgotten. "Exit code 9" was really NTSTATUS `0xC0000409` (STATUS_STACK_BUFFER_OVERRUN, i.e. `__fastfail`: what UCRT `abort()`, Rust aborts in native addons, and /GS stack checks raise). The libuv exit callback narrows the 32-bit `GetExitCodeProcess` value to `u8`, and `0xC0000409 & 0xFF == 9`. Two gaps compound into the masking, and the second is the one this PR is about. The coordinator classifies a worker death as a panic (which aborts the whole run, the behavior added in #30216) only by fatal signal. Windows never delivers a signal, so a native fault there was indistinguishable from `process.exit(N)`: the file got marked failed, a fresh worker was spawned, and the run carried on, which in CI turns a genuine native crash into a "flaky" retry. The `is_panic_status` comment described exactly this limitation. And since the printed exit code was the truncated one, the log did not even identify the crash. (#33720 separately widens the JS-visible `Exited::code` to match Node. This PR keeps `code` untouched, so it has no JS-visible effect and no dependency on that change; it stores the raw value alongside, and the two fields meet at the same struct, so whichever lands second reconciles them there.) ## Fix - `Exited` gains a `#[cfg(windows)] raw: u32` carrying the untruncated `GetExitCodeProcess` DWORD, set at its single Windows construction site (the libuv exit callback). - `is_panic_status` also treats a fixed allowlist of fatal NTSTATUS exit codes as panics, mirroring the POSIX fatal-signal list: access violation, in-page error, illegal/privileged instruction, the float and integer faults, stack overflow, heap corruption, `__fastfail`, CRT fatals, assertion failure. An allowlist rather than `code >= 0xC0000000` because high exit codes are not all faults: `0xC000013A` is Ctrl+C (the SIGINT analog), and foreign code in the worker can exit with arbitrary DWORDs (CRT `exit(-1)` is `0xFFFFFFFF`). `TerminateProcess` (taskkill, job limits) intentionally stays a per-file failure, like SIGKILL on POSIX. - `describe_status` prints the untruncated code, in hex for NTSTATUS-range values: `worker crashed: exit code 0xC0000409`. - The abort path's sibling termination used `kill(1)`, which libuv-win rejects with ENOSYS (it only maps SIGQUIT/SIGTERM/SIGKILL/SIGINT to `TerminateProcess`), so the newly reachable Windows abort would have waited on a busy sibling instead of stopping it. Both abort paths now use SIGKILL. - New `crash_handler.fastfail` binding in `bun:internal-for-testing`: dies like foreign native code with the crash handler provably out of the way on both platforms — `__fastfail` on Windows (kernel-terminated with `0xC0000409`, no VEH/SEH dispatch) and a raw SIGABRT on POSIX (dispositions reset first). Every existing crash-trigger binding routes through the crash handler, which exits with code 3 on Windows. A crash that does reach Bun's Windows crash handler still exits with code 3, which genuinely cannot be told apart from `process.exit(3)`; that case keeps the old behavior and is recognizable by its banner in the captured worker stderr. ## Verification The fix caught the real crash live: in this PR's own CI ([build 90096](https://buildkite.com/bun/bun/builds/90096), windows 2019 x64), the same zlib file's worker died again and the batch log now shows ``` ✗ test\js\node\zlib\zlib-estimated-size-gc.test.ts (worker crashed: exit code 0xC0000409) error: a test worker process crashed with exit code 0xC0000409 while running test\js\node\zlib\zlib-estimated-size-gc.test.ts. This indicates a bug in Bun or in a native addon, not in the test itself. Aborting. ``` instead of `exit code 9` and a silent continue. (The underlying zlib crash is reported separately.) Tests, mirroring the existing POSIX segfault test (hung sibling + crashing file): - Windows (`skipIf(!isWindows)`): a fastfail worker must produce the hex report, the banner, the abort, and the terminated sibling accounted as `aborted: sibling worker panicked`. Verified on windows-x64: fails on the released canary, passes with this build; with the classification short-circuited, the run reproduces the CI logs' exact `worker crashed: exit code 9` signature and carries on. - POSIX (`skipIf(isWindows)`): the same fixture dies by raw SIGABRT and must abort identically via the fatal-signal list. Fails on the released canary, passes with this build on linux x64 (debug+ASAN). `bun bd test test/cli/test/parallel.test.ts` matches the main-built baseline on both platforms (the pre-existing failures on Windows debug builds are assertion noise reported separately; Windows CI lanes run release builds and are unaffected), and the existing `process.exit(7)` mid-run test still reports `exit code 7` and continues on both. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Node imports the same URLs fine. ### Cause `data:` specifiers went through the module resolver's file-path handling before the scheme was recognized: - `VirtualMachine::resolve_maybe_needs_trailing_slash` rejects any specifier over the path-length cap with `ENAMETOOLONG` before the resolver's `data:` branch ever runs. - `normalize_specifier_for_resolution` and `normalize_specifier_for_loader` split the specifier at the first `?` as if it were a file query string. For a `data:` URL the `?` is part of the payload, so `import('data:text/javascript,export default "a?b=c"')` loaded truncated source and failed with `Unterminated string literal` (works in Node). ### Fix Skip the path-length cap and the query-string split when the specifier starts with `data:`, at both resolution and load. The payload is inline and never touches the filesystem, so neither path rule applies. Malformed `data:` specifiers (no comma) still fail with `InvalidDataURL` as before. This also fixes `new Worker(url)` with a long `data:` URL, which resolved through the same path. ### Verification New tests in `test/js/node/string-module.test.js` (the existing data-URL import coverage): a 200 KB percent-encoded import, a 200 KB base64 import (both exceed every platform's cap), and a `?` in the payload. All three fail on Bun 1.4.0 and pass with this change; the pre-existing tests in the file, `test/js/bun/resolve/import-query.test.ts` (file query-string semantics), `test/js/bun/resolve/esModule.test.ts`, `test/js/bun/resolve/import-meta.test.js`, and `test/bundler/esbuild/loader.test.ts` still pass. Verified the Worker scenario from #33596 directly: `new Worker("data:application/javascript;base64,...")` above the length cap fails with `NameTooLong` on Bun 1.4.0 and loads with this change.

Tearing down the VM while that step is in flight frees the native coder under the pool thread: ```js // ASAN build, BUN_DESTRUCT_VM_ON_EXIT=1 (the CI test runner sets this) const s = new CompressionStream("brotli"); const w = s.writable.getWriter(); const big = new Uint8Array(6 << 20); for (let i = 0; i < big.length; i += 3) big[i] = (i * 2654435761) >>> 24; w.write(big).catch(() => {}); w.close().catch(() => {}); s.readable.getReader().read().catch(() => {}); setTimeout(() => process.exit(0), 15); ``` ``` ==ERROR: AddressSanitizer: heap-use-after-free ... thread (Bun Pool 0) #0 UpdateNodes vendor/brotli/c/enc/backward_references_hq.c:468 ... #4 BrotliEncoderCompressStream vendor/brotli/c/enc/encode.c:1661 #5 CompressionStreamCoder::transform src/runtime/webcore/CompressionStreamCoder.rs:367 freed by: BrotliEncoderDestroyInstance CompressionStreamCoder__destroy JSCompressionStream.cpp:176 (CFinalizer) JSC::Heap::CFinalizerOwner::finalize -> Heap::lastChanceToFinalize ``` The same free-under-the-pool-thread happens on `worker.terminate()` / `process.exit()` inside a worker while a large write is in flight (`WebWorker::shutdown` -> `WebWorker__teardownJSCVM` -> `lastChanceToFinalize`). Other faces of the same report: READ 1 in `BrotliEstimateBitCostsForLiterals` / `UpdateNodes`, WRITE 4 in `StoreAndFindMatchesH10`. `DecompressionStream` has the identical finalizer shape, and zstd/zlib formats share the path. ### Cause The stream cell's CFinalizer (registered in the constructor) destroys `m_coder` unconditionally. During normal operation the in-flight task's `Strong` root keeps the cell from being swept, and the eager ClearAlgorithms release already defers on `m_asyncCodecInFlight`. But `Heap::lastChanceToFinalize` at VM teardown runs every finalizer regardless of roots, so the coder (brotli ring buffer + hasher, zlib window, zstd ctx) is freed while the pool thread is still inside `transform`. ### Fix Reference-count the coder. The JS cell holds one reference, released where it released before (finalizer, or the eager ClearAlgorithms path; both already null the cell's pointer first, so `CompressionStreamCoder__destroy` keeps its signature and call sites). Each in-flight `CompressionAsyncCtx` takes its own reference when the async step is scheduled and drops it with the ctx on the JS thread. The backend is freed when the last reference drops, so teardown releases the cell's hold but can no longer free the state under the pool thread. On the teardown paths where the completion never gets delivered, the coder is abandoned with the dying process instead of freed early, which is the bounded-leak tradeoff the worker teardown path already takes elsewhere. Related: #36983 fences `WebWorker::shutdown` on outstanding off-thread jobs, which closes the worker-terminate door from the other side (and is still needed for it: after this change, the worker repro's surviving report moves to `EventLoop::enqueue_task_concurrent` via `WorkTask::on_finish` on the freed worker loop, which is exactly the bug that PR addresses, now with a `WorkTask` stack). This change covers what the fence cannot: the main-thread `BUN_DESTRUCT_VM_ON_EXIT=1` exit path, and the coder's own lifetime independent of teardown ordering. ### Verification - New test in `test/js/web/streams/compression.test.ts` (ASAN-gated): fails on the unfixed build with the ASan report above, passes with the fix. - Main-thread repro: 5/5 clean runs with the fix (was UAF on every run before). - `test/js/web/streams/compression.test.ts` (37), `test/regression/issue/18413-all-compressions.test.ts`, `test/regression/issue/23314/zstd-large-decompression.test.ts`, and the four node webstreams compression compat tests all pass. --- **[review]** gate passed · iteration 0 · 4 files touched

;` where `unused` is never referenced), the bundler tree-shakes the `jsxDEV(...)` calls but previously still kept the import, because the synthesized Part was emitted with `can_be_removed_if_unused: false` and the linker's side-effect-import scan forced it live. With `--external react` the output carried a stray `import { jsxDEV } from "react/jsx-dev-runtime"`; with React bundled it pulled the entire `react` package (1k+ lines) into a bundle that contains no JSX at runtime. #### Repro ```tsx // test.tsx const myElement =
hello
; export default 'hi'; ``` ```sh bun build test.tsx --external react ``` Before: ```js import { jsxDEV } from "react/jsx-dev-runtime"; var test_default = "hi"; export { test_default as default }; ``` After: ```js var test_default = "hi"; export { test_default as default }; ``` #### Why is removing the import correct? The import is not user code; the bundler synthesized it to service JSX calls. If no JSX survives tree-shaking, the file is semantically identical to one with no JSX at all, which would not have received the import in the first place. The user has no expectation of the JSX runtime module's side effects from code they never wrote. esbuild currently keeps the import in the same scenario, but only because its synthesized part takes the same default. There is no correctness reason to keep it; Babel/SWC/TypeScript all only emit the import when JSX is present in their output, and a bundler that knows all JSX has been eliminated can do the same. #### How - Tag the synthesized JSX import Part as `PartTag::JsxImport` (the tag already existed, unused) with `can_be_removed_if_unused: true` and `force_tree_shaking: true`. - In `mark_file_live_step`, skip the side-effect-import scan for `JsxImport` parts so an external or side-effect-carrying JSX source does not force the part live. When JSX *is* used, the part is still pulled in via `part.dependencies`: the using part depends on the import part through `top_level_symbols_to_parts`, and step 6 of `scanImportsAndExports` wires the import part to the JSX source's wrapper via `generate_symbol_import_and_use`, so bundled CJS JSX sources (the real `react` case) are still included and run their top-level code. ### How did you verify your code works? New tests in `test/bundler/bundler_jsx.test.ts` cover, in both dev and prod: - external JSX source, all JSX dead: import dropped - external JSX source, JSX live: import kept - external JSX source, fragment-only dead JSX: import dropped - bundled CJS JSX source with no `sideEffects` field, all JSX dead: source not bundled (previously the whole module was bundled); `run` check confirms only the entry's own code executes - bundled CJS JSX source, JSX live: source still bundled, its top-level side effect still runs, `jsxDEV` still produces the expected element - two entry points, one with live JSX and one with dead JSX: only the live entry's chunk carries the import The three "kept when used" cases guard against regressing the existing behavior; the rest fail before this change and pass after. --- **[review]** gate passed · iteration 1 · 5 files touched

Main at 6089d0e83f does not compile: ``` error[E0599]: no variant, associated function, or constant named `JsxImport` found for enum `PartTag` --> src/js_parser/p.rs:1917:45 ``` (also at `src/js_parser/parse/parse_entry.rs:1966` and `:1981`) This is a semantic conflict between two PRs that each passed CI on their own merge base: - #36833 removed the then-unused `JsxImport`, `CjsImports`, and `ReactFastRefresh` variants from `PartTag` in `src/ast/nodes.rs` as dead code. - #35472, written before that removal, started tagging synthesized JSX runtime imports with `PartTag::JsxImport` in the parser and matching on it in `LinkerContext.rs`. The fix re-adds the `JsxImport` variant in its old position. The other two removed variants are still unused and stay gone. `PartTag` has no explicit `repr` and is never serialized, so the variant's position carries no meaning; matching the old order keeps the diff minimal against history. ### Why a test change? The build failure itself is the regression, so any test proves fail-before. The added test pins the one path of #35472's feature the suite did not cover: transpile-only output (`--no-bundle`, the same single-file path the runtime transpiler uses) never tree-shakes parts, so the synthesized JSX runtime import must survive even when every JSX expression is dead.

From 78da06a024e5062776694fd2daab6e347aca7cd3 Mon Sep 17 00:00:00 2001 From: robobun Date: Fri, 7 Aug 2026 19:00:15 -0700 Subject: [PATCH 185/304] Fix use-after-free in deepEquals when a getter mutates the object mid-comparison (#37168) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ### Problem `Bun__deepEquals` has heap-use-after-free when a getter on a nested object mutates one of the objects being compared. All entry points are affected: `Bun.deepEquals`, `expect().toEqual` / `toStrictEqual`, `assert.deepStrictEqual` / `deepEqual`, and `util.isDeepStrictEqual`. ```js // Malloc=1 repro.mjs const p1 = {}, p2 = {}; for (let i = 0; i < 8; i++) { p1['k'+i] = i; p2['k'+i] = i; } let f = 0; p1.a = { get x() { if (!f++) for (let i = 0; i < 2000; i++) p1['n'+i] = i; return 1; } }; p2.a = { get x() { return 1; } }; p1.z = 1; p2.z = 1; Bun.deepEquals(p1, p2, true); ``` ASAN (with `Malloc=1` so JSC's bmalloc routes through the system allocator): ``` heap-use-after-free READ of size 8 #0 CompactPropertyTableEntry::key() Structure.h #1 PropertyTable::forEachProperty #2 Structure::forEachProperty #3 Bun__deepEquals<...> bindings.cpp freed by: PropertyTable::destroyIndexVector <- PropertyTable::rehash <- PropertyTable::add <- Structure::addNewPropertyTransition <- JSObject::putDirectInternal ``` ### Cause The object fast path walks the structure's `PropertyTable` with `Structure::forEachProperty` and recurses into `Bun__deepEquals` from inside the lambda. Comparing a nested value can run a user getter; if that getter adds (or deletes) properties on the parent object, JSC takes the shared table off the old structure and rehashes it, freeing the index vector the outer walk is iterating. Every remaining sibling property is then read from freed memory and its stale offset fed to `getDirect()`. In release builds this shows up as a SEGV at a forged address or a wrong verdict. ### Fix Collect the (left, right) value pairs into a `MarkedArgumentBuffer` under `forEachProperty` with no side effects, then run `sameValue` and the recursive comparisons after the walk finishes. This is the same shape as `Object.assign`'s fast path (snapshot under `forEachProperty`, side-effectful work after). The buffer keeps the snapshotted values visible to GC, so allocation churn in a getter cannot collect them either. The reverse `o2` walk already did only direct structure reads and now also completes before any user code can run. Verdicts are unchanged for non-mutating comparisons (existing suites pass); a comparison whose getter mutates the object now deterministically compares the snapshot, which matches Node's behavior for the repro above (`true`). ### Verification - New test in `test/js/bun/bun-object/deep-equals.test.ts` (renamed from `deep-equals.spec.ts` to match the test naming convention): spawns an ASAN child with `Malloc=1` (bmalloc routed through the system allocator so ASAN can see the freed table) covering same-structure, mixed-structure, delete, right-side mutation, and GC-churn variants across all entry points. Fails before the fix (ASAN heap-use-after-free abort), passes after. - `test/js/bun/bun-object/`, `test/js/node/assert/deep-equal.test.ts`, `assert-typedarray-deepequal.test.ts`: 542 pass. - `test/js/bun/test/expect.test.js`: 415 pass. - `test/js/node/test/parallel/test-assert-deep-with-error.js`: 2 pass. ### Scope The same pattern exists in `JSC__JSValue__forEachPropertyImpl` in this file (the `Bun.inspect` / `console.log` property walk), where the formatter callback can run a nested value's `inspect.custom` mid-walk. Verified with ASAN to hit the same free/read pair. That is a pre-existing bug in the console/inspect subsystem and is intentionally excluded here; a follow-up fix for that site is in progress. The other `forEachProperty` sites (CommonJS export enumeration, HTTP header writing, the ordered/non-indexed iteration variants) run no user code inside the walk. --- **no test proof** · iteration 3 · Platform-specific test(s) that do not run on this machine.

The default-enabled `Symbol.for("nodejs.util.inspect.custom")` hook on a nested value is enough to trigger it: ```js // Malloc=1 repro.mjs const p = {}; for (let i = 0; i < 8; i++) p['k'+i] = i; let f = 0; p.a = { [Symbol.for('nodejs.util.inspect.custom')]() { if (!f++) for (let i = 0; i < 256; i++) p['n'+i] = i; return 'a'; } }; p.z = 1; console.log(Bun.inspect(p).length); ``` ASAN (with `Malloc=1` so JSC's bmalloc routes through the system allocator): ``` heap-use-after-free READ of size 8 #0 CompactPropertyTableEntry::key() Structure.h #1 PropertyTable::forEachProperty #2 Structure::forEachProperty #3 JSC__JSValue__forEachPropertyImpl bindings.cpp freed by: PropertyTable::destroyIndexVector <- PropertyTable::rehash <- PropertyTable::add <- Structure::addNewPropertyTransition <- JSObject::putDirectInternal ``` ### Cause The fast path of `JSC__JSValue__forEachPropertyImpl` walks the structure's `PropertyTable` with `Structure::forEachProperty` and invokes the formatter callback from inside the walk. The callback recursively formats the property value, which can run user code: a nested value's `inspect.custom`, or a getter on a built-in subclass (for example an overridden `Map.prototype.size`). If that code adds or deletes properties on the parent object, JSC rehashes the shared table, freeing the index vector the outer walk is iterating, and every remaining entry is read from freed memory. The fast-path guard only inspects the parent's structure, and a parent with plain data properties passes it; the hostile hook lives on a nested value. Same bug class as the deepEquals fix in #37168, which deliberately excluded this site. ### Fix Collect the entries (key, attributes, direct value) under `forEachProperty` with no side effects, then resolve remaining values and invoke the callback on the snapshot after the walk finishes. The values go in a `MarkedArgumentBuffer` so GC in a callback cannot collect them; keys are retained as `Identifier`s. The snapshot is per structure walk, so the prototype-chain restart loop still re-reads each prototype's live structure. Properties added to the object while it is being formatted are no longer printed: the walk now reflects the object as it was when formatting started. That matches Node, which collects the key list before formatting values. The other `forEachProperty` sites are unaffected: the non-indexed and ordered variants never take this fast path, and the remaining callers run no user code in the callback. ### Verification - New test in `test/js/bun/util/inspect.test.js` (ASAN-only, child spawned with `Malloc=1`) covering: `inspect.custom` adding properties via `Bun.inspect` and `console.log`, deleting properties, a `Map` subclass `size` getter, the prototype fast-walk of an own-property-less object, and GC churn inside the hook with object-valued siblings formatted afterwards. Fails before the fix (ASAN abort, empty stdout), passes after. - `test/js/bun/util/inspect.test.js`: 74 pass. `test/js/bun/console/`: 85 pass, 1 skip. - `inspect-error.test.js` minified-file snapshots and `inspect-error-leak.test.js` fail identically with and without this diff locally (pre-existing, unrelated to property enumeration). --- src/jsc/bindings/bindings.cpp | 48 ++++++++---- test/js/bun/util/inspect.test.js | 127 ++++++++++++++++++++++++++++++- 2 files changed, 159 insertions(+), 16 deletions(-) diff --git a/src/jsc/bindings/bindings.cpp b/src/jsc/bindings/bindings.cpp index 3b778b2c762c..59fd92da7d05 100644 --- a/src/jsc/bindings/bindings.cpp +++ b/src/jsc/bindings/bindings.cpp @@ -5452,6 +5452,21 @@ static void JSC__JSValue__forEachPropertyImpl(JSC::EncodedJSValue JSValue0, JSC: if (fast) { bool anyHits = false; JSC::JSObject* objectToUse = prototypeObject.getObject(); + + // The iter callback can run user code (a nested value's inspect.custom, Proxy + // traps) that adds properties to this object, rehashing the PropertyTable + // mid-walk (use-after-free).

charset=UTF-8 Content-Transfer-Encoding: 8bit ### Problem `NODE_COMPILE_CACHE` entry files contain the full post-transpile source and JSC bytecode of every loaded module. Bun created them with mode 0644 (so 0644 under the usual umask 022), inside 0755 directories. With `module.enableCompileCache()`'s default location (`$TMPDIR/node-compile-cache/v---/`) that lets any other local user read a user's cached module sources. Node v26.3.0 creates entry files with an explicit mode of 0600 (verified empirically: 0600 even under umask 000), while its directories are plain `mkdir` masked by umask. Repro (Linux, umask 022): ```sh printf 'module.exports=1; console.log("A")\n' > A.cjs NODE_COMPILE_CACHE=$PWD/cc bun A.cjs stat -c '%a %n' cc/*/* # bun: 644, node v26.3.0: 600 ``` ### Fix `bun_sys::Tmpfile::create` hardcoded `0o644`. Added `Tmpfile::create_with_mode` (with `create` delegating at 0644 so the other callers are unchanged), and the compile cache persist path now creates its tmpfile with 0600. The tmpfile-plus-rename flow preserves that mode on the final entry. Directory modes are left as-is, matching Node. ### Verification New test in `test/js/node/module/node-module-module.test.js` asserts both cache entries stat as 0600 (POSIX only; the fixture pins umask 022 so the assertion is deterministic). Fails on a build without this change (entries stat 644), passes with it. The existing compile cache tests (sha256 keying/acceptance, flush, self-kill persist) still pass. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Rewrites `Bun.XML`'s parser in the shape of the JSON parser: a Highway SIMD "stage 1" indexes every `<` `>` `&` `\r`, control character and encoded U+FFFE/FFFF (plus tab/newline/quotes/`=` inside tags, tracked with a MatchStar carry across 64-byte blocks), and stage 2 hops from index entry to entry — text runs, attribute values, comments, CDATA and PIs are never walked byte by byte — writing immutable `ObjectJSON`/`ArrayJSON` rows on a `JsonTape` instead of a `Vec` per object. Elements are parsed iteratively (explicit depth cap); the DTD and entity replacement text keep the byte-level scanner. Rows (JSON and XML alike) become JS values in one C++ call: objects via `putDirect`, arrays via `MarkedArgumentBuffer` + `constructArray`, keys and short values through the VM's `jsonAtomStringCache` as `JSON.parse` does, with three string paths keyed on the tape's encoding (UTF-8 / Latin-1 / UTF-16). An 8-bit JS string is parsed byte-per-character as is and yields Latin-1 strings without any re-encoding. `Bun.{XML,JSONC,TOML,YAML,JSON5}.parse` recycle a per-thread arena instead of a `mi_heap` per call. **JS level** — `bench/xml/xml.mjs` with the CI-built PR binary (`bunx bun-pr 37146`, linux-x64) vs main, ms/iter, lower is better (one loaded machine → read as ratios). Input is a JS string: ASCII files take the Latin-1 in-place path, the CJK-heavy one the native UTF-16 path. | document | PR (compact) | main | × | PR `{compact:false}` | main | txml | fast-xml-parser

every byte that can change the parse — `<`, `>`, `&`, line ends, quotes and `=` inside tags — and the parser then hops from one of those positions to the next, so character data, attribute values,

The existing R-2 comment already states this rule for `reject()`; it was not applied to `signal_drained()`. ### Fix - `Err` path: move the action out of the cell first, then `signal_drained()`, then `reject`. - Non-`Err` path: keep `signal_drained()` before the fulfill (a backpressure-gated producer must observe the installed action), but re-take the action with `let`-`else` and return if a re-entrant consumer already settled it. The non-last-chunk tail only appends to the buffer and never takes the action, so it needs no guard. ### Verification The in-tree producers do not re-enter synchronously from the drain signal (fetch and server request bodies schedule socket resumes, the rewriter defers behind its `driving` flag), so the interleaving is not reachable from plain JS. The deterministic test therefore installs a stub producer through `bun:internal-for-testing` (`SourceHandle::TestingCancelOnDrain`, whose `ready()` re-enters `on_cancel`), parks `body.text()` on a streaming fetch response, and severs the connection. The severed connection matters: the tasklet then delivers `Err` straight to `on_data` with the action still in its cell, while `abort()` first errors the JS stream, whose `done()` path cancels the native source and consumes the action before `on_data` runs. On the unfixed ordering the fixture panics on every run: ``` panic: called `Option::unwrap()` on a `None` value core::option::unwrap_failed ::on_data src/runtime/webcore/ByteStream.rs:317 ::on_body_received ``` With the fix it prints `rejected:TypeError` and exits 0. ``` bun bd test test/js/web/fetch/fetch.stream.test.ts -t "buffer action consumed re-entrantly" # deterministic red/green bun bd test test/js/web/fetch/fetch.stream.test.ts -t "parked body consumers" # abort-path stress coverage ``` --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

That works on MySQL but not on MariaDB: selecting from a `json` column returns the raw JSON text as a string on both the binary and the text protocol. ```js const sql = new SQL({ url: "mysql://root@127.0.0.1:3306/bun_sql_test", max: 1 }); await sql`CREATE TEMPORARY TABLE t (a json)`; await sql`INSERT INTO t (a) VALUES (${JSON.stringify({ b: 1 })})`; const [row] = await sql`SELECT a FROM t`; console.log(typeof row.a, row.a); // MariaDB: string '{"b": 1}' MySQL: object { b: 1 } ``` ### Cause JSON results are only parsed when a column's wire type is `MYSQL_TYPE_JSON` (0xf5). MariaDB has no server-side JSON type: `json` columns are `LONGTEXT` and arrive as `MYSQL_TYPE_BLOB` (0xfc) with a text charset, so the JSON arms in `DecodeBinaryValue.rs` / `ResultSet.rs` never fire. MariaDB's way to tell them apart is the `MARIADB_CLIENT_EXTENDED_TYPE_INFO` capability. The server advertises its extended capabilities in the last 4 of the handshake's 10 reserved bytes (a MariaDB 10.2+ server marks itself by leaving `CLIENT_LONG_PASSWORD`, `CLIENT_MYSQL` in MariaDB's dialect, unset); the client requests them in the last 4 of the handshake response's 23 filler bytes. Once negotiated, every column definition carries an extended metadata block and JSON columns are marked `format=json`. Bun never negotiated the capability: it skipped the reserved bytes and always sent zero filler. ### Fix - `Capabilities.rs`: add `MariaDBCapabilities` (same macro as `Capabilities`); request only `MARIADB_CLIENT_EXTENDED_TYPE_INFO`, intersected with what the server advertised. - `HandshakeV10.rs`: parse the server's extended capabilities from the reserved bytes, gated on `CLIENT_LONG_PASSWORD` being unset; zero for MySQL. - `HandshakeResponse41.rs` / `SSLRequest.rs`: write the negotiated extended capabilities into the last 4 filler bytes. For MySQL servers nothing is negotiated, so the bytes stay zero and the packets are byte-identical to before. On TLS connections the SSLRequest is the packet MariaDB reads the extended capabilities from, so it carries them too. - `ColumnDefinition41.rs`: when the capability is negotiated, parse the extended metadata block (a lenenc blob of `(int<1> kind, string value)` pairs between `org_name` and the fixed-length fields). Columns marked `format=json` are remapped to `MYSQL_TYPE_JSON`, restricted to wire types whose values are length-encoded strings so the row decoders cannot desync. Kind-0 entries (type names like `uuid`, `inet4`) are skipped and those columns keep decoding as strings. Malformed blobs (truncated or overrunning lengths) reject with `InvalidEncodedInteger` / `InvalidEncodedLength`. This fixes `json` columns and JSON function results (`JSON_OBJECT`, `JSON_EXTRACT`, ...) on both protocols, matching the existing MySQL behavior. Old MariaDB (pre-10.5) does not advertise the capability and keeps the previous behavior. This is the read-side counterpart of #37125, which fixed binding object parameters on MariaDB; the two are independent. ### Tests `test/js/sql/sql-mariadb-json.test.ts`: - Mock-server tests (no container needed) byte-assert the negotiation: against a MariaDB-style handshake advertising `0x3d`, the client must request exactly the extended-type-info bit and then parses a `format=json` `MYSQL_TYPE_BLOB` column into an object on both protocols. The mock only attaches extended metadata when the client actually negotiated it, like a real server, so these fail on an unfixed build (capability bytes 0, value returned as a string). Two guards pin the compat behavior: a server advertising nothing gets a zero request and keeps string results, and a MySQL-style server (`CLIENT_LONG_PASSWORD` set) gets all-zero filler even with garbage in the reserved bytes. - A TLS mock (SSLRequest, then a mid-stream TLS upgrade) byte-asserts the SSLRequest payload (32 bytes, extended-type-info bit at offset 28) and decodes a `format=json` column end-to-end over TLS; that packet is the one a MariaDB server honors for TLS connections and was previously uncovered. - Fault-injection mocks send corrupt extended metadata (a truncated inner length, and a length past the blob's end) and assert the query rejects with `ERR_MYSQL_INVALID_ENCODED_INTEGER` / `ERR_MYSQL_INVALID_ENCODED_LENGTH`, covering both error paths of the new parser on the prepared and text protocols. - A docker-backed suite against real MariaDB (new `mariadb_plain` compose service, baked datadir like `Dockerfile.mysql-plain`) covers json columns mixed with other columns, json arrays/NULL, JSON function results, `.raw()`, re-executed prepared statements, and UUID/INET6 columns whose extended type entries must be skipped without desyncing the decoder. It auto-starts its container only under an explicit `BUN_TEST_SERVICE_mariadb_plain` override, the CI docker coordinator, or CI docker, so a machine with a half-provisioned docker daemon skips instead of failing. Verified locally against MariaDB 11.8.6 (all 9 tests pass; 5 of the mock tests fail before the fix). Full `test/js/sql/` suite passes locally apart from pre-existing environment-dependent failures that reproduce identically on the released build. --- **[review]** gate passed · iteration 0 · 13 files touched

Missing `worker_threads` API surface (`resourceLimits`, `trackUnmanagedFds`, `moveMessagePortToContext`, …) is out of scope. ### Lifetime model - WebCore's `ActiveDOMObject` / `ScriptExecutionContext` registry is restored, so `Worker`, `MessagePort`, `BroadcastChannel` and `WebSocket` are stopped in a real stop phase before the JSC VM is destroyed instead of from inside `~VM`. `Worker` is split, as upstream, into the script object and a `WorkerMessagingProxy` that owns the parent↔thread relationship. - Worker threads are refcounted and **joined** by their parent (Node's model). A parent tracks its children, stops them in its own stop phase and joins them before its VM goes away, so `terminate()` propagates through nested workers and resolves only once the thread is gone. No `pthread_exit`. - `VirtualMachine::teardown()` is the one ordered sequence for a finished worker and for main-thread exit: exit handlers run, then script is forbidden and everything the VM owns is stopped natively (WebCore objects, servers, listeners, watchers, sockets, dns, sqlite, in-flight `fetch`/S3 requests, `Bun.build` passes waiting on this VM's plugins — as in Node, no `'close'`/`'error'` handler runs after `'exit'`) → timers cancelled, children joined, in-flight off-thread work waited for or released, VM handle closed, queued work released → JSC VM destroyed → loops freed (uSockets; libuv on Windows) → destroy. - Every off-thread completion — thread pool (fs, crypto, zlib, transpiler, `dns.lookup`, shell builtins, `Bun.Archive`, password hashing), the HTTP thread (`fetch`, S3), the bundle thread, child-process waiter, fs watcher threads, napi async work / threadsafe functions, JSC helper threads — reaches a VM only through a per-VM `VmHandle` that teardown closes. Pool work is one typed carrier (`bun_jsc::Job`) whose JS-affine half only the owning thread can touch and teardown releases; work whose storage lives in JS objects or on another thread is counted and waited for; work that can block on an external party is registered so the stop phase aborts it. A late completion is refused and released by its producer instead of touching a dead VM. `EventLoop` has no cross-thread entry points any more. - A worker's "may run script" gate closes the moment its stop is requested — a parent's `terminate()`, its own `process.exit()`, or an uncaught error — not when its thread gets around to tearing down (Node's `can_call_into_js` / `is_stopping`). Every native→JS entry consults it (timer and immediate callbacks, event listeners, socket/server callbacks, pool-job completions, JSC deferred work, N-API), so nothing dispatches into a worker that is being stopped, whichever event source it came from. Promise settlement is the one native→promise boundary and never accepts an empty value: a JS conversion that a termination interrupted becomes "reject with the pending exception", which itself yields to the termination. - The event loop stays fair under producers that outpace it: one turn refills from the concurrent queue a bounded number of times; message drains take a fixed budget per task (a bounded batch per lock acquisition, never a whole-queue hand-back) and continue after the loop has polled; a UDP socket is read a bounded number of batches per readiness event. A worker posting faster than its parent deserializes, or a datagram socket that never runs dry, no longer holds that loop's timers, I/O — or its own pending stop. - Cross-thread costs of the handle are kept off hot paths: its read-mostly state sits on its own cache line away from the counters other threads update, and C++ tests the "may run script" byte inline rather than calling out per callback. ### Behaviour changes (Node parity) - `parentPort` is a real `MessagePort`: `parentPort.close()` ends the worker, `.ref()`/`.unref()` work, `receiveMessageOnPort` returns falsy messages, and parent messages are delivered only after the worker's entry module has run (a preload's un-awaited `import()` does not count as the entry running). - A worker with a pending top-level await starts and receives messages; it exits 13 if the await never settles, and a top-level await rejecting later fails the worker at that moment. - `await worker.terminate()` resolves the exit code (`1` for a running worker); `threadId` stays valid until exit; everything a worker posted before it exited is delivered before `'exit'`/`'close'`; `postMessage()` to a terminated worker is a no-op rather than an error; a rejection that is only a consequence of `terminate()` (a lookup or request cancelled by the stop) is not reported as the worker's `'error'`. - `process.exit()` / worker exit no longer runs microtasks or `nextTick`s queued before it. A worker's own `process.exit()` or uncaught error runs its `'exit'` handlers; a parent `terminate()` does not. `process.exit()` from inside (nested) `node:vm` contexts in a worker unwinds like any exception, and a `node:vm` `timeout` inside a worker no longer leaves the worker unable to run script afterwards. - Workers inside a process that has an IPC channel do not get a `process.send()` of their own over the process's channel fd. - N-API's pure constructors/accessors are callable while an exception is pending (as in Node), so node-addon-api can build the `Error` for a call a termination interrupted instead of aborting the process. - Assigning a non-function to `port.onmessage` releases the keep-alive a handler took. - Servers, listeners, sockets, UDP sockets, watchers and `dns.Resolver`s are closed by the exiting VM rather than left to GC finalizers; sqlite connections a VM opened are checkpointed and closed by that VM's exit; a `Bun.build` whose VM goes away mid-build is cancelled (its plugin requests failed, the pass finished) rather than abandoned or waited on, and one still queued behind other builds is released without waiting for them. - A connect-path DNS lookup (`Bun.connect`, `net`, `WebSocket` to a hostname) is process-wide and outlives the thread that happened to issue it: on macOS a worker exiting mid-lookup no longer answers every other thread's coalesced waiters with an error (and caches it for the TTL). - An addon's external-buffer finalizers run when the Worker that loaded it exits (`napi_create_external_{arraybuffer,buffer}`), as Node's environment teardown finalizes every remaining reference. - Releasing the last keep-alive from an immediate or a late promise reaction (e.g. `port.close()` inside `setImmediate`) is noticed before the loop parks. - Windows: a worker thread closes its loops. Open pipe/tty/process handles and readers mid file-read are closed through their owners in the stop phase, and requests still in flight are drained there — against a live VM that still accepts (and then awaits) the follow-on work a completion may start — before anything is released; sockets over named pipes and TLS-over-duplex sockets join the stop phase; a reader dropped mid-read keeps the buffer its pending read lands in. Two of the crashes were in JavaScriptCore rather than Bun: a `TerminationException` raised while the module loader resolves an import continued into `finishLoadingImportedModule` (fixed in oven-sh/WebKit#391, picked up by the WebKit version bump here). A worker parked in `Atomics.wait` with no timeout still cannot be terminated (#32802); that needs a JSC change and is tracked separately. ### Testing New tests accompany each behaviour fix (worker_threads, Web Worker lifecycle edges — `terminate()` at every phase of dns/fs/build/vm/napi/http work, message ordering and flooding, process exit ordering, sqlite). Seven more upstream `test-worker-*` files are vendored (one of them, the message-port infinite-message-loop test, passes only with these changes) and previously todo/skipped worker-related napi and regression cases run again. LeakSanitizer validation is turned back on for the ~70 worker / MessagePort / BroadcastChannel test files that were exempt. A source lint rejects laundering a `JsResult` into an empty `JSValue`. Main-thread `process.exit()` keeps its current fast path by default; the full main-thread teardown stays behind `BUN_DESTRUCT_VM_ON_EXIT=1`. Workers always tear down fully. ### Known / not in this PR - A worker parked in `Atomics.wait` with no timeout still cannot be terminated (#32802; needs a JSC change). - `worker_threads` message throughput through the real `MessagePort` is ~0.8× the previous ad-hoc path in a flood microbenchmark (round-trip latency and Web `Worker` messaging are unchanged); a follow-up, not a behaviour regression. - Windows: several concurrent connects to `localhost` can leave one connect stuck (pre-existing; reproduces on current releases; DNS-coalescing on the connect path). - A UDP socket whose receive buffer never drains (e.g. one echoing datagrams to itself on a fast machine) keeps its event loop from running anything else, including a worker's own exit; pre-existing loop-fairness issue, most visible on Windows, follow-up. - Memory a burst of concurrent workers used stays resident after they exit (sequential worker churn plateaus; it is the concurrent peak that is not returned to the OS) — allocator thread-exit policy, follow-up. - `Worker` start semantics for a never-settling top-level await, file-stream fairness on a saturated loop, and a few diagnostics-only items found while fuzzing are tracked separately.

After `await Promise.all(proms)` for the last batch of 16 subprocesses, every stream has finished from JS's point of view (stdout EOF, `stdin.end()` resolved, `exited` resolved), but a pipe fd that had a poll registered is closed by `bun_io::Closer` on the work pool rather than on the JS thread (`src/io/pipes.rs` `close_impl` → `Closer::close`, by design so a blocking `close()` never stalls the loop). On a loaded machine those pool tasks can lag the JS thread by a few ms, so the last batch's stdin/stdout/pidfd descriptors (~44) are still open at the instant `getMaxFD()` runs. Reproduced on Linux x64 with 2×nproc busy loops running: 5 of 30 rounds of the same spawn/await/count loop saw `maxFD 7 -> 51` immediately after the await and `7` again 10 ms later; 0/30 idle, and macOS didn't reproduce at all (which matches the CI distribution). The assertion is unchanged; it now polls for the count to return to the baseline (10 ms steps, up to 1 s) before asserting, the same way `expectMaxObjectTypeCount` right below it already waits for object counts. With that loop the loaded Linux reproduction is 0/40. Review pointed out that `spawn-streaming-stdout.test.ts` has the same shape, at both sample points: the final count is read right after the last batch's `Promise.all`, and the baseline is read right after batch 1's, so in-flight closes can inflate the baseline as well (a failure the final poll alone can't recover from). That file now settle-polls the baseline, then polls the final count down only while it is above the baseline and asserts `<=` instead of exact equality: the baseline there is a heuristic with no pre-spawn ground truth (46a337c in #6724 moved it after the first batch on purpose), so a count below it is not a leak, and a max-based settle check can rarely stop a little high. The stdin test keeps its exact `toBe` since its baseline is taken before any spawn. ### How did you verify your code works? Reproduction/verification above (release binary on Linux); `bun bd test test/js/bun/spawn/spawn-streaming-stdin.test.ts` passes locally. Both test files also pass under a debug ASAN build and 8/8 rounds each under 2×nproc CPU load on the release binary. --- **[stamp-90s]** gate passed · iteration 3 · 2 files touched

The adapters' code is ported from Node's `lib/internal/webstreams/adapters.js`, where these primordials exist. The affected call sites are the `write()` implementations of `newStreamWritableFromWritableStream` (`Writable.fromWeb`) and `newStreamDuplexFromReadableWritablePair` (`Duplex.fromWeb`): when a string chunk reaches `_write` undecoded with a non-utf8 encoding, the adapter decodes it and passes a plain `Uint8Array` to the web sink. In Bun that path threw instead: ```js const { Writable } = require("node:stream"); const ws = new WritableStream({ write(c) { console.log(c); } }); const w = Writable.fromWeb(ws); w._write("68656c6c6f", "hex", err => console.log("done", err)); ``` Node prints `Uint8Array(5) [ 104, 101, 108, 108, 111 ]`; Bun threw: ``` TypeError: TypedArrayPrototypeGetBuffer is not a function. (In 'TypedArrayPrototypeGetBuffer(chunk)', 'TypedArrayPrototypeGetBuffer' is undefined) at write (internal:webstreams_adapters:371:103) ``` The normal `writable.write(str, encoding)` path is unaffected in both runtimes: with `decodeStrings: true` (the default) the stream machinery converts strings to Buffers before `_write`, and with `decodeStrings: false` the adapter passes the string through unchanged. The branch only runs when `_write` is invoked with a string directly, which the `Writable` implementer contract allows. Node succeeds there; Bun threw. The fix adds the three getters to `internal/primordials.js` using the same `getGetter(Uint8Array, ...)` pattern as the existing `TypedArrayPrototypeGetLength`, which keeps the adapter code identical to upstream Node. Since this failure mode is silent (a missing export destructures to `undefined` and nothing throws until a cold path calls it, and tsc cannot see it because `$require` is untyped), the PR also adds a source lint, `test/internal/source-lints/primordials-exports.test.ts`, asserting that every name pulled out of `require("internal/primordials")` anywhere in `src/js` is actually exported. It covers direct and multi-line destructures, the `const primordials = require(...)` indirection used by `internal/util/inspect.js`, and member reads, and it fails with the exact `file: name` pairs. On the tree without this fix it reports the three names above; with the fix the whole surface is clean. ### How did you verify your code works? Added two tests to the webstreams adapters section of `test/js/node/stream/node-stream.test.js` covering the `Writable.fromWeb` and `Duplex.fromWeb` paths. Both fail on current Bun with the TypeError above and pass with this change; the same assertions hold on Node v26.3.0. The full `node-stream.test.js` file, the vendored `test-whatwg-webstreams-adapters-*` suites, and `test/internal/source-lints/` pass with the debug build, and the new lint fails against the unfixed `primordials.js` listing exactly the three missing getters. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Same for `Bun.file(path).text()` and `fs.readFileSync(path, "utf8")` when the file is between 2 GiB and 4 GiB - 1 bytes (a sparse `truncate -s 2G big.txt` reproduces it). Release builds die with a silent SIGABRT; debug builds fail with: ``` ASSERTION FAILED: data.size() <= MaxLength WTF/wtf/text/StringImpl.h(891) StringImplShape(uint32_t, std::span, unsigned) ``` Sizes of 4 GiB and above already threw catchable errors, and 2^31 - 1 worked, so only the [2^31, 2^32) range crashed. ### Cause The Rust-side guards in front of WTF string construction (`bun_core::String::max_length()`) only consult `Bun__stringSyntheticAllocationLimit`, which defaults to 2^32 - 1. The hard cap enforced by `RELEASE_ASSERT` in the `StringImplShape` constructors is `WTF::StringImpl::MaxLength` = 2^31 - 1. The C++ conversions in `helpers.h` already clamp (`len > Bun__stringSyntheticAllocationLimit || len > WTF::String::MaxLength`); the Rust side missed the second half, so external-string creation for lengths in [2^31, 2^32) passed the guard and tripped the assert. ### Fix - `String::max_length()` clamps the synthetic limit to `WTF::StringImpl::MaxLength` (2^31 - 1). - The `create_external*` guards compare with `>` instead of `>=`, so 2^31 - 1, the largest valid WTF length, still works. - `ZigString__toJSONObject` also checks `WTF::String::MaxLength`, so `Blob.json()` at these sizes reports `ERR_STRING_TOO_LONG` instead of falling through to `JSONParse` on a null string. - `BunString__createUTF8ForJS` rejects oversized all-ASCII input with `ERR_STRING_TOO_LONG` instead of asserting. - Error messages report the real limit (2147483647, matching the C++ `ErrorCode.cpp` text) instead of "2^32-1". `Blob.text()` / `Bun.file().text()` now throw `ERR_STRING_TOO_LONG`; `fs.readFileSync(path, "utf8")` reports `ENOMEM` like the existing >= 4 GiB and `/dev/zero` paths (the fs layer speaks errno). `Buffer.prototype.toString` already threw `ERR_STRING_TOO_LONG` for these sizes via its own `WTF::String::MaxLength` check in `JSBuffer.cpp`. ### Verification - `test/js/web/fetch/blob-oom.test.ts`: subprocess tests for `Blob.text()`, `Blob.json()` and `Bun.file().text()` at 2^31 bytes (abort before, catchable error after), plus the existing synthetic-limit assertions updated to the corrected message. - `test/js/node/fs/fs-oom.test.ts`: `readFileSync(file, "utf8")` at 2^31 bytes throws `ENOMEM`; at 2^31 - 1 bytes still decodes to a 2147483647-length string. The fixture files are sparse so only the in-memory read costs 2 GiB, and each case runs in a subprocess. - Manually verified 4 GiB inputs still produce the same catchable errors as before, and 2^31 - 1 still succeeds on all three faces. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

Fixes the `test/cli/run/multi-run.test.ts` flake on the macOS runners (13 of the last ~80 main builds; darwin 14/26, x64 and arm64). The failures look unrelated at first — a script's output missing entirely (`Received: ""`), only the *last* script's output missing (`third-output`, `post-ran`), or a script running that should have been skipped: ``` ✗ sequential: pre failure with --no-exit-on-error still runs next group Expected to not contain: "build-shouldnt" Received: "test | test-ran\nbuild | build-shouldnt\n" (prebuild is `exit 1`; build ran anyway, and after test) ``` They share one trigger: the script's process has **already exited** when `ProcessHandle::start()` calls `process.watch_or_reap()`. On macOS registering `EVFILT_PROC` on an exited pid fails with `ESRCH`, `watch_or_reap` falls back to a blocking `wait4`, and the exit handler runs *synchronously inside `start()`*. That needs a few ms of scheduling delay between `posix_spawn` and the kevent call — routine on the loaded mac fleet, never on Linux (a pidfd on a zombie just polls readable later). Two bugs then fire in `multi_run.rs`: 1. **Exit was treated as "finished".** `process_exit` flushed the partial-line buffers, printed `Done`, decremented `remaining_scripts` and cascaded to dependents without waiting for the stdout/stderr `BufferedReader`s to reach EOF. Whatever hadn't been read yet was dropped, and if this was the last script `while !state.is_done()` ended and `bun run` exited before reading a byte → the empty / truncated outputs. 2. **The initial start loop re-read `remaining_dependencies` while iterating.** A synchronous finish inside `prebuild.start()` cascades: `skip_dependents` zeroes `build`'s counter (meaning "skipped") and starts `test`. The loop then reaches `build`, sees `0`, and starts it → `build-shouldnt`, after `test`. (It also re-started `test`; in a debug build that's a `subtract with overflow` panic in `start_dependents`.) Both reproduce exactly with a `sleep(50ms)` inserted before `watch_or_reap()` on an otherwise unmodified build: `run --sequential --no-exit-on-error build test` prints `build | Done` after `test | Done` and panics; `run --parallel x` for `x: "echo a; echo b"` prints only `x | Done in 61ms`. **Fix:** a script is finished when its process has exited *and* both pipes have ended (the same rule `lifecycle_script_runner.rs` already uses; also what `concurrently` does by waiting for `'close'`), and the roots are collected before any is started. With the same artificial 50 ms delay the whole test file passes. Behaviour note: because a script now finishes when its output ends, a script that leaves a background process holding its stdout keeps `bun run --parallel` alive until that process closes it (previously the output was cut off at the shell's exit). Ctrl-C behaviour is unchanged. ### How did you verify your code works? - New test `timing edge cases > output written after the script's shell exits is not dropped` (a script whose detached child writes 300 ms after the shell exits): fails on the current canary (`Received: "late | early-line\nother | other-ran\n"`), passes with this change. - `bun bd test test/cli/run/multi-run.test.ts`: 119 pass, both as-is and with the 50 ms delay simulating the CI condition. There is no hook to force the already-exited-at-watch timing from a test, so the double-start half is covered by the existing tests only under that condition. ### Same class: `bun run --filter` (filter_run.rs) Review caught that `filter_run.rs`, the sibling copy of this code path (dispatched for `--filter`/`--workspaces` without `--parallel`/`--sequential`), has the same two bugs verbatim: exit treated as finished without waiting for pipe EOF, and the initial start loop re-reading `remaining_dependencies` while iterating. This PR now applies the same fix there. Since both of its `BufferedReader`s share the `ProcessHandle` as their parent (the done callback cannot tell which pipe ended), it tracks not-yet-ended pipes with a per-handle `remaining_fds` counter, the same pattern `lifecycle_script_runner.rs` uses, and collects the roots before starting any. Verification: same-shape test in `test/cli/run/filter-workspace.test.ts` fails on the current canary (`Received: "pkg-late go: early-line\npkg-late go: Exited with code 0\n"`, the late line dropped) and passes with this change; `bun bd test test/cli/run/filter-workspace.test.ts` 57 pass, `test/cli/run/run-quote.test.ts` 6 pass, `test/cli/install/bun-run.test.ts` 292 pass. --- **no test proof** · iteration 4 · Platform-specific test(s) that do not run on this machine. Deferring to CI, which covers all platforms: test/cli/run/filter-workspace.test.ts test/cli/run/multi-run.test.ts ### Abort semantics (review catch) Review also caught that the EOF gate broke aborts: a script that exited leaving a detached child holding its pipes would keep an aborted run (failing script with exit-on-error, or Ctrl-C) alive until that child closed them, where it previously exited immediately. Fixed in both runners: finishing is idempotent (a `finished` flag), `abort()` sweeps `maybe_finish` over every handle after killing so exit alone finishes a script once aborted, and the run loops re-check `is_done()` after an abort instead of blocking in a tick that no event may wake. Covered by two new tests (a failure abort under `--parallel`, and a process-group SIGINT under `--filter`), which pass on this branch and on the unfixed baseline (the EOF gate introduced the hang, so the gate relies on the late-output tests for fail-before). --------- Co-authored-by: robobun <117481402+robobun@users.noreply.github.com> --- src/runtime/cli/filter_run.rs | 82 ++++++++++++++++--- src/runtime/cli/multi_run.rs | 91 ++++++++++++++++----- test/cli/run/filter-workspace.test.ts | 113 +++++++++++++++++++++++++- test/cli/run/multi-run.test.ts | 78 +++++++++++++++++- 4 files changed, 331 insertions(+), 33 deletions(-) diff --git a/src/runtime/cli/filter_run.rs b/src/runtime/cli/filter_run.rs index 7cfd582d26ac..5c25bf252ed2 100644 --- a/src/runtime/cli/filter_run.rs +++ b/src/runtime/cli/filter_run.rs @@ -56,6 +56,13 @@ pub(crate) struct ProcessHandle<'a> { stdout: BufferedReader, stderr: BufferedReader, + /// Pipes started and not yet at EOF/error; a script is finished only when + /// its process has exited and this is 0 (see `State::maybe_finish`). + remaining_fds: i8, + /// Set by the `maybe_finish` that counts this script out of + /// `remaining_scripts`, so a later pipe/exit event or the abort sweep + /// cannot finish it twice. + finished: bool, buffer: Vec, process: Option, @@ -159,16 +166,20 @@ impl<'a> ProcessHandle<'a> { { if let Some(stdout) = stdout_fd { let _ = sys::set_nonblocking(stdout); + handle.remaining_fds += 1; handle.stdout.start(stdout, true)?; } if let Some(stderr) = stderr_fd { let _ = sys::set_nonblocking(stderr); + handle.remaining_fds += 1; handle.stderr.start(stderr, true)?; } } #[cfg(not(unix))] { + handle.remaining_fds += 1; handle.stdout.start_with_current_pipe()?; + handle.remaining_fds += 1; handle.stderr.start_with_current_pipe()?; } @@ -210,10 +221,23 @@ impl<'a> ProcessHandle<'a> { true } - fn on_reader_done(&mut self) {} + fn on_reader_done(&mut self) { + debug_assert!(self.remaining_fds > 0); + self.remaining_fds -= 1; + let mut state_ref = self.state; + // SAFETY: state backref valid (see start()). + let state = unsafe { state_ref.get_mut() }; + let _ = state.maybe_finish(self); + } fn on_reader_error(&mut self, err: &sys::Error) { let _ = err; + debug_assert!(self.remaining_fds > 0); + self.remaining_fds -= 1; + let mut state_ref = self.state; + // SAFETY: state backref valid (see start()). + let state = unsafe { state_ref.get_mut() }; + let _ = state.maybe_finish(self); } } @@ -233,7 +257,7 @@ impl<'a> ProcessHandle<'a> { let mut state_ref = self.state; // SAFETY: state backref valid (see start()). let state = unsafe { state_ref.get_mut() }; - let _ = state.process_exit(self); + let _ = state.maybe_finish(self); } fn loop_(&self) -> *mut bun_io::Loop { @@ -339,7 +363,17 @@ impl<'a> State<'a> { Ok(()) } - fn process_exit(&mut self, handle: &mut ProcessHandle<'a>) -> crate::Result<()> { + /// A script is finished once its process has exited *and* both pipes have + /// reached EOF: the exit notification can arrive before the last output + /// has been read, and finishing then would drop that output (or, for the + /// last script, exit before printing it).

The S3 client extracted `ListObjectsV2` results, `` bodies (simple requests and download streams) and the multipart `UploadId` with `index_of("")` scans. That returned XML-escaped text verbatim — S3 escapes every text node, so a key `Tom & Jerry.mp4` came back with the entity still in it, and the same for prefixes, continuation tokens and error messages — could be confused by markup-looking text, and half-parsed ill-formed bodies. Now that #37146 landed a fast conforming parser, these paths read the response through `bun_parsers::xml` (node shape, so text is byte-exact: entities/CDATA decoded, whitespace in keys preserved) via a small `s3/xml_response.rs` helper. `list_objects.rs` shrinks from a ~350-line state machine to field mapping. Behavior changes worth calling out: - Escaped text is decoded everywhere (the actual bug). - A `200` ListObjectsV2 body that is not a well-formed `` now **rejects** with `code: "InvalidResponse"` (message points at `encodingType: "url"` for keys with control characters) instead of resolving with a partial/empty listing. The existing tests that answered `<>` just to inspect the request URL now answer ``. - 404s whose `` has no `` still map to `NoSuchKey`. Also folded in: the per-thread recycled parse arena is factored out of the `Bun.{XML,JSONC,TOML,YAML,JSON5}.parse` scaffold as `RecycledArena` and shared with the S3 path (no `mi_heap` per response), and the `xml_parse` feature counter moves from the parser to its API entry points so internal use isn't counted. Not in scope: `uploadId` is still interpolated into the query string unencoded (pre-existing; AWS upload IDs are URL-safe and are validated as printable ASCII). ### How did you verify your code works? - New test in `test/js/bun/s3/s3-list-objects.test.ts` covering escaped keys/prefixes/owner, CDATA keys, `&#x…;` refs, `RestoreStatus` nesting, whitespace-exact keys, and decoded `` code/message on 404 — fails with `USE_SYSTEM_BUN=1`, passes on the build. - `bun bd test` green for `s3-list-objects` (36 pass / 3 skip), `s3-storage-class`, `s3-list-checksum-algorithm`, `s3-list-encode-overflow`, `s3-stream-error-gc`, `s3-requester-pays`, `s3-connection-close`, and the multipart upload-id / NetworkSink mock tests in `s3.test.ts`; XML suites unchanged. - Drove the debug binary against a local mock endpoint for all four paths (list, error body, 404 without ``, malformed 200, multipart create→complete). - The credentialed `s3.test.ts` suites are skipped locally (no secrets); CI runs them. --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> --- src/bun_core/Global.rs | 3 +- src/bundler/ParseTask.rs | 1 + src/bundler/transpiler.rs | 1 + src/parsers/xml.rs | 1 - src/runtime/api/XMLObject.rs | 1 + src/runtime/webcore.rs | 4 + src/runtime/webcore/s3/download_stream.rs | 112 ++--- src/runtime/webcore/s3/list_objects.rs | 489 ++++------------------ src/runtime/webcore/s3/multipart.rs | 41 +- src/runtime/webcore/s3/simple_request.rs | 78 ++-- src/runtime/webcore/s3/xml_response.rs | 135 ++++++ test/js/bun/s3/s3-list-objects.test.ts | 165 +++++++- 12 files changed, 476 insertions(+), 555 deletions(-) create mode 100644 src/runtime/webcore/s3/xml_response.rs diff --git a/src/bun_core/Global.rs b/src/bun_core/Global.rs index 56cff6a2b82d..56a912aec7f0 100644 --- a/src/bun_core/Global.rs +++ b/src/bun_core/Global.rs @@ -386,7 +386,8 @@ pub mod features { pub fn yaml_parse_inc() { YAML_PARSE.fetch_add(1, core::sync::atomic::Ordering::Relaxed);

From JS it looked like success. This treats `Editor::None` as "not found" at those checks (`EditorContext::found()`), making both errors reachable; nothing is spawned. Why now: `test/js/bun/util/open-in-editor-gc.test.ts` › "survives re-entrant calls from option getters" (added in #36920) has been timing out in the Linux parallel lane since the day it landed (debian/ubuntu/alpine; builds 89333, 90274, 90329, 90444, 90571). It was written on the assumption that with an empty `PATH` and no `EDITOR` those calls are inert; in fact each run started eight of those editor threads racing the fixture's exit. I could not reproduce the hang itself locally (0/250, idle and loaded), so I can't claim more than: the fixture now does no spawning at all, which is what the test intended, and the API reports the failure it always meant to. The test keeps its re-entrancy coverage and now asserts the four error messages instead of swallowing them. ### How did you verify your code works?

Fixes the `test/js/node/test/parallel/test-fastutf8stream-reopen.js` flake (15 of the last ~80 main builds, every Linux distro + macOS): ``` AssertionError: Expected values to be strictly equal: + '' - 'after reopen\n' at test-fastutf8stream-reopen.js:52:22 (also :94:22) ``` Root cause is in `Utf8Stream` (`src/js/internal/streams/fast-utf8-stream.ts`), not the test. After `reopen()` the `fileOpened` callback emits `'ready'` and then unconditionally does `process.nextTick(() => this.emit('drain'))`. The test's `'ready'` listener calls `stream.write('after reopen\n')`, which starts an async `fs.write` and sets `#writing = true` — so the scheduled `'drain'` fires on the next tick **while that write is still in flight**. The test's `once('drain')` takes it as "buffer flushed", `readFile()`s the destination, and races the pending write. (When the write does complete, `#release` emits a second, genuine `'drain'`.) You can see the double drain directly — this prints `writing = true` on the first drain in both Bun (before this change) and Node: ```js stream.once('drain', () => { renameSync(dest, dest + '-moved'); stream.reopen(); stream.once('ready', () => { stream.write('after reopen\n'); stream.once('drain', () => console.log('drain; writing =', stream.writing)); // true }); }); ``` Node carries the same code but its libuv threadpool is a strict FIFO, so the earlier-queued write practically always lands before the later `readFile`. Bun's pool makes no such promise, and under CI load the read wins occasionally. Fix: the reopen tick only emits `'drain'` if no write is in flight; otherwise the write's completion emits it, as it already does everywhere else in the class. Sync mode is unaffected (a sync write in `'ready'` has finished by the time the tick runs). ### How did you verify your code works? - New deterministic test in `test/js/node/fs/fs.test.ts` that holds the `fs.write` callback (via the `fs` override option) across the reopen and asserts no `'drain'` is emitted until the write is released. Fails on the previous build (`drainedWhileHeld === true`), passes now. - `test-fastutf8stream-*.js` (all 14) pass with the debug build; `-reopen.js` 40/40 under 8-way parallel stress. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

From 5938918e77aa5b618498b488e89943a4bc4ad83f Mon Sep 17 00:00:00 2001 From: robobun Date: Sat, 8 Aug 2026 20:36:40 -0700 Subject: [PATCH 202/304] resolver: auto-resolve extensions for wildcard exports/imports targets (#36299) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #29679. Fixes #10001. ## Repro Packages like `@modelcontextprotocol/sdk` ship an `exports` wildcard whose target has no extension: ```json "exports": { "./*": { "types": "./dist/esm/*.d.ts", "import": "./dist/esm/*", "require": "./dist/cjs/*" } } ``` `import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio"` expanded subpath `server/stdio` to `./dist/esm/server/stdio`, a file that doesn't exist on disk (the file is `stdio.js`). Before this change Bun errored `Cannot find module ...`, matching Node.js but breaking these packages. A closely related shape from #10001: wildcard `imports` with a `.js` target that points at a `.ts` source: ```json "imports": { "#app/*": "./app/*.js" } ``` With `app/main.ts` on disk, `import '#app/main'` failed for the same reason: the substituted path (`./app/main.js`) wasn't a file and the existing TypeScript rewrite (`.js` -> `.ts` from `load_as_file`) never ran. ## Cause `resolve_target` in `src/resolver/package_json.rs` set `ExactEndsWithStar` only when the substituted result literally ended with `*`, true only when the subpath was empty. For non-empty subpaths the status was `Exact`, which in `handle_esm_resolution` skipped any extension probing. ## Fix 1. Always flag wildcard-pattern expansions as `ExactEndsWithStar` so the consumer knows the result came from a `"./*"`-style key. 2. New helper `probe_wildcard_extensions` runs when the pattern-expanded target isn't a file (called from both the miss arm and the Dir arm): - **Target has no extension** -> append the configured extension order (`.js`, `.mjs`, `.ts`, ...). - **Target ends with `.js`/`.jsx`/`.mjs`** -> swap for `.ts`/`.tsx`/`.mts`. Same rewrite `load_as_file` already does for plain file loads, with the same `node_modules` gating on the `.mjs` arm only (#5426). 3. Exact-key matches (`"./client": "./dist/esm/client/index.js"`) and non-wildcard `"./dir/"`-style keys are untouched. 4. Deletes the now-dead `Status::ModuleNotFoundMissingExtension` variant (its only setter was the hint loop this replaces). ## Comparison with other tools Verified against Node.js 26.3.0, TypeScript 5.8.2, esbuild 0.28.1, webpack 5.99.5, and Vite 6.2.3: | | extensionless (#29679) | `.js`→`.ts` (#10001) | |---|---|---| | Node.js | ❌ | ❌ | | TypeScript `moduleResolution: "bundler"` | ❌ | ✅ | | esbuild | ❌ | ✅ | | webpack / enhanced-resolve | ✅ | ❌ | | Vite | ✅ | ✅ | | Bun (this PR) | ✅ | ✅ | The `.js`→`.ts` rewrite (#10001) matches TypeScript, esbuild, and Vite; it is also what Bun already does for plain relative imports via `load_as_file`. The extensionless probe (#29679) matches webpack and Vite. Only Vite handles both. ## Verification `#29679`: ```ts import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio"; console.log(StdioServerTransport); // [class StdioServerTransport] ``` `#10001`: ```ts // package.json: "imports": { "#app/*": "./app/*.js" } // app/main.ts: export const foo = "ts file"; import { foo } from "#app/main"; console.log(foo); // ts file ``` New test cases in `test/js/bun/resolve/resolve.test.ts` cover: - Extensionless wildcard import resolves to `.js` target - Extensionless wildcard import resolves to `.mjs` target - Explicit `.js` extension still works - Exact-key exports are unaffected - Truly missing subpath still errors - CJS `require()` resolves via the `require` condition - Explicit-extension wildcard target does not double-probe - Sibling `.js` resolves when a same-named directory exists - `imports` wildcard with `.js` target resolves `.ts` file - `.mjs` target resolves `.mts` file - `.jsx` target resolves `.tsx` file - Self-referencing `exports` wildcard with `.js` target resolves `.ts` file - Real `.js` sibling wins over `.ts` - Exact (non-wildcard) `.js` target is not rewritten to `.ts` Also bumps the dir-cache stress test's timeout to 20s (it was already at ~4.9s/5s under debug+ASAN on main before these tests were added). --- src/resolver/package_json.rs | 14 +- src/resolver/resolver.rs | 192 ++++++++++-- test/bundler/esbuild/packagejson.test.ts | 9 +- test/js/bun/resolve/resolve.test.ts | 362 ++++++++++++++++++++++- 4 files changed, 537 insertions(+), 40 deletions(-) diff --git a/src/resolver/package_json.rs b/src/resolver/package_json.rs index 001fee422afb..a664c50d861d 100644 --- a/src/resolver/package_json.rs +++ b/src/resolver/package_json.rs @@ -1321,9 +1321,6 @@ pub enum Status { /// The package or module requested does not exist.

Node runs the same addon cleanly. ### Cause `NapiEnv::drain()` deleted an async cleanup hook's handle as soon as the hook body returned. But the addon owns that handle: in Node the handle is freed only by `napi_remove_async_cleanup_hook` (node/src/node_api.cc deletes it unconditionally), and the addon may legitimately call that after the hook has run, since that call is how it signals the async cleanup is complete. Here the call comes from a threadsafe function finalizer that `abortThreadSafeFunctions()` invokes after the cleanup hooks have drained. ### Fix - `drain()` no longer frees the handle after invoking the hook. - `napi_remove_async_cleanup_hook` (via `NapiEnv::removeAsyncCleanupHook`) erases the hook from the set if it is still registered, then frees the handle unconditionally, matching Node. - The handle no longer stores a `HookSet` iterator (it could dangle across rehashes); handle identity is plain pointer equality. Related: #34136 addresses the separate semantic of waiting for an async cleanup hook that completes from a background thread. It does not cover this case: the removal here is queued behind env teardown itself, so handle lifetime has to be decoupled from the hook's return regardless. ### Verification New fixture `test/napi/napi-app/test_async_cleanup_hook_tsfn_release.c` (adopted from the issue) compared against Node via `checkSameOutput`: - `USE_SYSTEM_BUN=1 bun test test/napi/napi.test.ts -t 'hook handle stays valid'`: fails (segfault at address 0x88) - `bun bd test test/napi/napi.test.ts -t 'hook handle stays valid'`: passes - `bun bd test test/napi/napi.test.ts -t cleanup`: 27 pass - The issue's standalone repro prints all three addon lines and exits 0 under the debug ASAN build, matching Node. --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

It isn't flaky — LSan caught a real leak the test exists to surface: ``` Direct leak of 392 byte(s) ... in Blob::do_read_file (NewReadFileHandler) Indirect leak of 320 byte(s) ... ``` `Bun.file(..).text()` (and every file-backed Blob read) boxed a completion handler holding the promise and a duped Blob, and handed `ReadFile` the erased `(ctx, run)` pair inside its **off-thread** payload, with `type Js = ()`. Only `run` — the completed-read path — reclaimed that box. A read whose worker stopped first (refused when the pool tried to complete it, or still queued when the loop stopped) freed the `ReadFile` and forgot the handler. ### Fix The completion is JS-thread state, so on POSIX it is now the job's `Js` side — `ReadFileCompletionFns` (`ctx` + `run` + `cancel`, `JsAffine`, cancels on `Drop`): - `then` completes it; - at teardown the VM's job list releases it **on its own thread** (cancel → the handler and its promise/Blob are dropped where they may be); - a refused read frees only the off-thread `ReadFile`. That is the partition the `Job` machinery already enforces — no per-read "VM gone" code, nothing JS-affine reachable from the pool. `ReadFileUV` (Windows, JS thread throughout) keeps the same triple as a field and cancels it if dropped unfinished. `read_bytes_to_handler`'s *borrowed* context is told (`ECANCELED`) rather than freed, since its caller owns it and waits for exactly one callback. ### Verification - `worker-refused-completion.test.ts` 15/15 — its `Bun.file().text()` row is what caught my first attempt (cancelling in place dropped a `Strong` off the JS thread; the debug assert fired), and passes with the JS-side design. - `worker-terminate-funnels.test.ts` 10/10, `blob.test.ts` 46/46, `bun-file.test.ts`, `bun-write.test.js` 47/47; `rust:check-all` 10/10. - The leak itself is only observable under LSan; the x64-asan lane's funnel `fs` row is the before/after signal. `WriteFile` has the same `(ctx, run)` / `type Js = ()` shape and very likely the same latent leak on a stopped worker; not touched here (nothing has flagged it yet) — happy to follow up with the same treatment. --- src/runtime/webcore/Blob.rs | 64 +++++--- src/runtime/webcore/blob/read_file.rs | 225 +++++++++++++------------- 2 files changed, 158 insertions(+), 131 deletions(-) diff --git a/src/runtime/webcore/Blob.rs b/src/runtime/webcore/Blob.rs index 6a6151444011..3e9b5efb447a 100644 --- a/src/runtime/webcore/Blob.rs +++ b/src/runtime/webcore/Blob.rs @@ -464,14 +464,12 @@ impl BlobExt for Blob { read_file::ReadFileUV::start::>( // `bun_vm()` returns the live VM for this global; the event - // loop outlives any in-flight async fs request. `start` - // takes the already-erased `*anyopaque` (caller casts); `H` - // (turbofish) supplies `Handler::run` for the callback. + // loop outlives any in-flight async fs request. global.bun_vm().event_loop(), self.store().expect("infallible: store present").clone(), self.offset.get(), self.size.get(), - handler.cast(), + handler, ); return promise_value; } @@ -482,7 +480,6 @@ impl BlobExt for Blob { self.store().expect("infallible: store present").clone(), self.offset.get(), self.size.get(), - handler, ) .unwrap_or_else(|e| bun_core::handle_oom(Err(e))); // Create the Promise only after the store has been ref()'d. @@ -492,7 +489,11 @@ impl BlobExt for Blob { let promise_value = unsafe { (*handler).promise.value() }; promise_value.ensure_still_alive(); - read_file::ReadFile::schedule(file_read, global); + read_file::ReadFile::schedule( + file_read, + read_file::ReadFileCompletionFns::of(handler), + global, + ); debug!("doReadFile: read_file_task scheduled"); promise_value @@ -536,6 +537,20 @@ impl BlobExt for Blob { // across the async read by contract; exclusive borrow scoped to the call.

ASAN (debug builds on current main): ``` ERROR: AddressSanitizer: SEGV on unknown address 0xfffffffffffffff1 SUMMARY: AddressSanitizer: SEGV in __asan::Allocator::Deallocate ``` which is `free(0x1)`: the backtrace is `___interceptor_free` <- drop of `MarkedArrayBuffer` <- drop of `StringOrBuffer` <- `drop_in_place>` <- `Job::release_refused` (or the worker-thread teardown release of queued jobs). On a release allocator the same free is undefined behavior rather than a clean abort. Repro (fails every run on current main, round 1): ```js // main terminates a worker that keeps 64 fs.readFile() calls of an EMPTY file in flight const { Worker, isMainThread, parentPort } = require("worker_threads"); const fs = require("fs"), path = require("path"); const empty = path.join(__dirname, "empty.txt"); if (isMainThread) { fs.writeFileSync(empty, ""); let n = 0; const again = () => { const w = new Worker(__filename); w.on("message", () => w.terminate().then(() => (++n < 40 ? again() : (console.log("survived", n), process.exit(0))))); }; again(); } else { const go = () => fs.readFile(empty, go); for (let i = 0; i < 64; i++) go(); setTimeout(() => parentPort.postMessage("busy"), 20); } ``` ### Cause A zero-byte read builds its result Buffer from an empty `Box<[u8]>` (`node_fs.rs` pre-stat path: `heap::into_raw(slice.to_vec().into_boxed_slice())`). An empty boxed slice has no backing allocation, so its pointer is `NonNull::dangling()` = `0x1`. `MarkedArrayBuffer::from_bytes` stamped `owns_buffer: true` on it anyway. That lie is harmless on the delivery path: `MarkedArrayBuffer::to_js` special-cases `byte_len == 0` and never frees, and `JSValue::create_buffer*` install no deallocator for empty slices ("An empty `Box<[u8]>` has no backing allocation"). But a result that is never delivered is released by `destroy()`, which does `if owns_buffer { free(ptr) }` and frees the dangling pointer. The first paths to actually drop an undelivered owned result are the refused-job paths from the worker teardown rework in #37075: a completed pool job refused by the dead VM (`Job::release_refused`), and teardown releasing already-queued jobs. Before that rework the same scenario hung in terminate() instead of crashing. ### Fix `MarkedArrayBuffer::from_bytes` no longer claims ownership of an empty slice (`owns_buffer: !bytes.is_empty()`), matching the existing zero-length handling in `to_js` and `JSValue::create_buffer*`. `destroy()` then has nothing to free, which is correct: there is no allocation. No behavior change for delivered buffers; the zero-length `to_js`/`to_node_buffer` paths ignore the pointer and the ownership flag entirely. ### Verification - The repro above crashes round 1 on current main (debug ASAN) and survives 40 worker generations with the fix. - New test `terminate with in-flight zero-length fs.readFile results does not wild-free` in `test/js/web/workers/worker-terminate-lifetime.test.ts`: fails on main (ASAN SEGV in the spawned process), passes with the fix. - Full `worker-terminate-lifetime.test.ts` and the fs family of `worker-terminate-funnels.test.ts` pass with the fix (the dns.lookup test in the lifetime file fails on pristine main with an unrelated, already-tracked LSan leak of the node:fs binding). --- **no test proof** · iteration 2 · Platform-specific test(s) that do not run on this machine.

Fixes an unreleased regression from #37206 on main: a script that backgrounds a helper now blocks `bun run --parallel` (and every later `--sequential` script) until the helper exits. ```json { "scripts": { "orphan": "sleep 25 & echo orphan-parent-exits", "quick": "echo quick-done" } } ``` ``` bun run --parallel quick orphan # main: prints output, then sits 25s before exiting bun run --sequential orphan quick # main: quick does not START for 25s ``` Plain `bun run orphan` returns in ~0.1s, and so did both flags before #37206. Any script that daemonizes something without redirecting its stdio hits this: `"db": "pg_ctl start &"`, `"dev": "server & watcher"`, ssh-agent/Xvfb-style helpers. **Cause:** #37206 made a script finished only when its process has exited *and* both stdout/stderr pipes reach EOF (so output that the exit notification beats is not dropped). A backgrounded grandchild inherits the pipe write ends, so EOF never comes until it dies, and the runner waits. The abort path already special-cased this; the normal-exit path did not. `bun run --filter` (`filter_run.rs`) has the same code and the same hang. **Fix:** on process exit (unless the run is aborted), drain what is already readable, then force-end any pipe still open: - The drain (`BufferedReader::read`) preserves the #37206 guarantee: everything the script wrote before exiting is in the kernel pipe buffer at exit time, so it is read and printed before the script is marked done. The macOS already-exited-at-watch scenario that #37206 fixed still gets its full output. - The force-end (`deinit`, which fires no callbacks) means a write end held by a leftover child no longer delays the run; the accounting is done directly (`ended` flag in `multi_run.rs`, `remaining_fds = 0` in `filter_run.rs`). - Aborted runs are unchanged: exit alone finishes, pending output is dropped. - On Windows there is no synchronous drain primitive for libuv pipes; data not yet delivered at exit is dropped, as it was before the EOF gate existed. One behavioral consequence, reflected in the updated tests: output a detached child writes *after* the script's process has exited is no longer shown (the pipe is closed at exit). #37206 had introduced "keep reading until the last holder closes the pipe", and that is exactly the behavior that turns daemonizing scripts into hangs. ### How did you verify your code works? On unfixed main (debug build), the repro above hangs until killed (`--parallel`: prints output then sits; `timeout 12` exits 124) and `--filter '*' orphan` does too. With this change all three finish in ~0.1s with full output, including the `orphan | Done` line that previously never printed. Tests (all fail on the unfixed build by hanging into the test timeout, pass with the fix): - `multi-run.test.ts`: "a detached child holding the pipes does not delay the script's finish" (rewritten from #37206's late-output test: early output still printed, the run no longer waits 30s for the child, `--sequential` starts the next script), and a new `sleep 30 & echo ...` test for `--parallel` completion. - `filter-workspace.test.ts`: same reshape of the late-output test for `--filter`. - `bun bd test test/cli/run/multi-run.test.ts`: 121 pass - `bun bd test test/cli/run/filter-workspace.test.ts`: 58 pass - `bun bd test test/cli/run/run-quote.test.ts`: 6 pass - `bun bd test test/cli/install/bun-run.test.ts`: 292 pass - `bun run rust:check-all`: 10 ok (all platform targets) --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

From 6a50e86da3ae5f2adee190b1de3904838859008f Mon Sep 17 00:00:00 2001 From: robobun Date: Sun, 9 Aug 2026 16:15:04 -0700 Subject: [PATCH 209/304] resolver: lock DirEntry map probes against the in-place stale-generation rewrite (#37274) Fixes #37266 Fixes #23773 ## Crash In [build 90948](https://buildkite.com/bun/bun/builds/90948) (ubuntu 25.04 aarch64), the `reload() while Bun.build() resolves the same directory` subprocess in `test/js/bun/util/filesystem_router.test.ts` died 22ms in with ``` panic: Segmentation fault at address 0x25 ``` instead of printing `matches 2000 builds-ok true`. The branch did not touch the resolver or router (its diff against main is empty for those modules), and the same test passed in the surrounding ~9 runs of the same code, so this is a low-probability race. It did not reproduce locally: ~3000 stress runs of the fixture (linux x64 release and debug+ASAN, windows aarch64 release, with cpu pinning, oversubscription, and `MIMALLOC_PURGE_DELAY=0` variants) produced 0 failures, nor did ~150 further runs of a `Bun.resolveSync`-from-plugin variant modeled on #23773. The buildkite artifact for that build has expired from the network I can reach, so the trace could not be symbolized; the fix below closes the remaining windows of the already-proven race class rather than a bisected instruction. #23773 is the same crash family observed in the wild on linux aarch64 (about 1 in 20 builds of a large project): `Segmentation fault at address 0x0` with `Entry.symlink`'s cache access (`fs.zig:397`) inlined into `finalizeResult`, reached from `Bun.resolveSync` inside a bundler plugin's `onResolve`, which is the JS thread running `finalize_result`'s unlocked probe concurrently with bundler-thread re-reads. ## Cause `RealFS::entries_at` and `read_directory` rewrite a cached `DirEntry` in place when a resolver with a newer generation re-reads the directory: `data.clear()` plus `*e_ptr = new_entry`, which drops the old `data: StringHashMap<*mut Entry>` and frees its bucket allocation. #34271 made the `entries_at` rewrite take `entries_mutex`, and the route-loader iteration sites already snapshot the map under the same lock. Three windows remained: 1. **Unlocked map probes.** The resolver lookup sites probed `.data` after the lock was released: `finalize_result`, `handle_esm_resolution`, `load_index_with_extension`, `probe_wildcard_extensions`, `Transpiler::run_env_loader` (all via `get_entries_ref`), and `load_as_file` / `load_extension` (via the `EntriesOption` slot captured after `read_directory` returned, with SAFETY comments incorrectly claiming "entries_mutex held"). A concurrent stale-generation rewrite frees the buckets mid-probe; a probe walking freed memory can load a garbage `*mut Entry` and fault at a small absolute address, which matches `0x25`. This is the same mechanism #34271's ASAN trace proved fires in this test, just on the lookup side instead of the iteration side, and `load_as_file` is the hottest instance (every relative-file import). 2. **`need_stat` published before `cache`.** `Entry::kind`/`symlink` cleared `need_stat` first and wrote the resolved `cache` after, with plain `Cell` ops. The fast path reads `need_stat` without the per-entry mutex, so on a weakly ordered CPU a reader could observe `need_stat == false` while the `cache` write was not yet visible, or mid-store: a torn read of the 16-byte `Interned` symlink faults inside `as_bytes`. This window needs entries whose kind is not known from `getdents` (symlinks, or filesystems returning `DT_UNKNOWN`), which is also consistent with firing on CI but not on local ext4/tmpfs/NTFS. 3. **Recycled entries overwrote a live cache.** When a re-read's `getdents` result disagreed with the cached kind, `add_entry_with_store` rewrote `cache` (kind plus symlink) in place under the per-entry mutex. A lock-free reader that had already observed `need_stat == false` reads `cache` without that mutex, and no store ordering can publish anything to a reader that loaded the stale flag, so the overwrite could tear a populated `Interned` under it. On a `DT_UNKNOWN` filesystem this fired on every re-read of every entry. ## Fix - `DirInfo::get_entry(generation, query)`: generation-checked lookup of one basename in a single `entries_mutex` critical section. The returned `EntryLookup` wraps a pointer into the process-lifetime `EntryStore`, so it stays valid after unlock; only the map walk needed the lock. The `get_entries_ref` probe sites now go through it (or through an explicit guard plus `get_entries_ref_locked` where the listing fd is captured in the same critical section). The now-unused unlocked `get_entries_ref` is removed. - `EntriesOption::lookup(query)` does the same for the `read_directory`-based sites (`load_as_file`, `load_extension`), returning the lookup and the listing fd from one critical section; `dir_and_fd()` covers the watch-registration read. `load_extension` takes the slot handle instead of a bare `&DirEntry`. - `run_env_loader` copies the listing's basenames out under `entries_mutex` and lets the dotenv loader probe the copy, instead of probing the live map between `.env` file reads. - `Entry.need_stat` is an `AtomicBool`: Acquire fast-path load, Release store after the `cache` write, so a reader that skips the mutex is guaranteed to see the completed `cache` write. - The recycle path only publishes `need_stat = true` and no longer rewrites `cache`; the next `kind()`/`symlink()` re-stats under the per-entry mutex, and a reader that raced the flag sees the old cache, stale but untorn (`set_cache_kind` had no other callers and is removed). - **Enforcement**: `DirEntry::get` / `get_comptime_query` / `has_comptime_query` debug-assert that the calling thread holds `entries_mutex`, so the next unlocked probe fails deterministically in debug builds instead of surfacing as a rare segfault. The callers that probed without the lock are converted: the dotenv loader always takes a `DirEntryKeys` basename snapshot copied out under the lock (the `DirEntryProbe` impl for the live `DirEntry` is removed so the type system forces the copy, covering `run_env_loader`, `PackageManager::init`, and the lockfile printer), PackageManager's lockfile-presence probe and `bun pm view`'s package-name probe take the uncontended guard, and the hot reloader's changed-file probe runs under the lock. - API cleanup from the same audit: `DirInfo::get_entries` (raw-pointer return documented as "callers prove exclusivity locally", which is the claim the deleted `run_env_loader` deref made and this PR proved false) is removed along with the now-uncalled `RealFS::entries_at`; `get_entries_ref_locked` becomes `pub` for the one-critical-section snapshot pattern; `get_entries_const` documents which fields may be read unlocked. Known residual same-value races are left alone and are not crash vectors: the recycle path's `existing.dir = self.dir` always rewrites identical bytes (the re-read passes the old `DirEntry`'s interned dir through), and `DirEntry.fd` is a word-sized field read where still unlocked. The two remaining different-value `set_cache_symlink` writers (the `getFdPath` path in `finalize_result` and `dir_info_uncached`) still race lock-free `cache` readers in principle; closing those needs reader-side locking or an atomic cache and is left for a follow-up. The lazy `abs_path` fill has its own torn-read window with a symbolized trace from an earlier occurrence of this same test crash (address `0x31`, also ~24ms, Debian 13 aarch64); #34411 already covers that and is complementary to this PR. `src/jsc/hot_reloader.rs` has a similar unlocked probe on the watcher thread, left for a separate change. ## Why there is no new test The fixture that crashed is already the regression test for this race class, and the windows here are sub-microsecond interleavings: ~3000 runs of it against an unfixed build (including 55 debug+ASAN runs, the configuration that catches the freed-bucket read as a heap-use-after-free) produced 0 failures, as did 155 release and 35 debug+ASAN runs of a dedicated `Bun.resolveSync`-from-`onResolve` fixture modeled on #23773's trace, so no honest test can fail without the fix. The fix is verified by analysis plus the class precedent: #34271's ASAN trace demonstrates the identical free-while-probing mechanism on the iteration sites this PR's lookup sites share. ## Verification - `bun bd test test/js/bun/util/filesystem_router.test.ts`: 33 pass (including the 40-round race test) - `bun bd test test/js/bun/resolve/resolve.test.ts`: 73 pass (wildcard exports extension probing) - `bun bd test test/bundler/esbuild/packagejson.test.ts`: 84 pass (exports map resolution) - `bun bd test test/bundler/bundler_edgecase.test.ts`: 134 pass (extension probing, js-to-ts rewrites) - `bun bd test test/bundler/bun-build-api.test.ts`: 52 pass - `bun bd test test/cli/run/env.test.ts`: 96 pass (`.env` discovery through the copied-keys probe) - `bun bd test test/cli/hot/hot.test.ts`: 12 pass, `test/cli/watch/watch.test.ts`: 8 pass - Stress on the fixed debug+ASAN build: 25 long + 150 short fixture runs, 0 failures - `cargo clippy -p bun_resolver -p bun_bundler` clean --- src/bundler/transpiler.rs | 27 +- src/dotenv/env_loader.rs | 26 +- src/dotenv/lib.rs | 6 +- src/install/PackageManager.rs | 24 +- src/install/lockfile.rs | 23 +- src/jsc/hot_reloader.rs | 17 +- src/resolver/dir_info.rs | 70 ++--- src/resolver/fs.rs | 98 ++++--- src/resolver/lib.rs | 73 +++-- src/resolver/resolver.rs | 449 ++++++++++++++++------------- src/runtime/cli/pm_view_command.rs | 11 +- src/runtime/cli/run_command.rs | 22 +- 12 files changed, 498 insertions(+), 348 deletions(-) diff --git a/src/bundler/transpiler.rs b/src/bundler/transpiler.rs index c6848d9bfce9..536e3ea26598 100644 --- a/src/bundler/transpiler.rs +++ b/src/bundler/transpiler.rs @@ -766,16 +766,23 @@ impl<'a> Transpiler<'a> { merge_tsconfig_jsx_into(tsconfig, &mut self.options.jsx); } - let Some(dir) = dir_info.get_entries(self.resolver.generation) else { - return Ok(()); + // Copy the listing's basenames out under `entries_mutex`, + // refreshing it at our generation in the same critical + // section: concurrent resolvers rewrite the `DirEntry` map in + // place under that lock, and `dot_env::Loader::load` does + // file I/O between probes. + let dir = { + let _entries_lock = bun_resolver::fs::FileSystem::instance() + .fs + .entries_mutex + .lock_guard(); + match dir_info.get_entries_ref_locked(self.resolver.generation) { + Some(entries) => dot_env::DirEntryKeys( + entries.data.iter().map(|(k, _)| Box::from(&**k)).collect(), + ), + None => return Ok(()), + } }; - // `get_entries` returns `*mut bun_resolver::fs::DirEntry` - // (BSSMap-owned). `dot_env::Loader::load` takes - // `impl DirEntryProbe` (bun_dotenv sits below `bun_resolver` - // in the crate graph); `bun_resolver::fs::DirEntry` impls it. - // SAFETY: BSSMap singleton owns `*dir`; single-threaded path — - // sole `&mut` for the call. - let dir: &mut bun_resolver::fs::DirEntry = unsafe { &mut *dir }; // `Env.files: Box<[Box<[u8]>]>` but `Loader::load` // wants `&[&[u8]]`.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problem `test/cli/test/parallel.test.ts > --parallel: a test producing a >64MB result line is truncated, not treated as a crash` is one of the most frequent flakes in CI right now: 19 failures across 17 branches in the last 400 builds, every one on the macOS x64 test lane, spread over six different agents. Signature: ``` 867 | expect(result).not.toBe("TIMEOUT"); error: expect(received).not.toBe(expected) Expected: not "TIMEOUT" ``` The spawned `bun test --parallel=2` run blows past the test's 60s deadline. Reproduced on an idle macOS 14 x64 CI host with a current canary: the two-file repro takes **89 seconds**, CPU-bound (92s user time). `sample` shows 5294 of 5317 samples in `_platform_memmove` under the IPC flush path. ## Cause `Channel::flush` (the fd-3 IPC channel used by `bun test --parallel`) drained the outgoing backlog like this: write once, then `drain_front(w)`, i.e. memmove the entire unsent remainder to the front of the buffer, once per writable event. The kernel accepts one send-buffer chunk per event, and macOS socketpairs default to roughly 8KB (the extra-fd socketpair gets no buffer-size bump, unlike stdio fds 0-2). For the 64MB `TestDone` frame this test generates, that is ~8200 writable events, each memmoving ~64MB: about **512GB of memmove for one frame**, which is the 89 seconds. Linux socket buffers are ~26x larger, so the same quadratic stays near a second there and never trips the deadline, which is why the flake is exclusive to darwin x64 (darwin arm64 has the memory bandwidth to squeak under 60s). ## Fix Track a cursor (`out_head`) of bytes already accepted by the kernel instead of draining the front after every partial write, and compact only once the sent prefix is at least as large as the unsent tail. Each compaction is charged to the bytes it discards, so total compaction cost is linear in bytes sent. No protocol or behavior change; Windows uses the `uv_write` path and is unaffected. ## Verification - Linux debug build with the extra-fd socketpair buffers temporarily forced to 8KB (local-only patch) to mimic macOS: the 68MB-frame repro goes from **9.2s unfixed to 1.4s fixed** under identical conditions, with identical output (1 pass, 1 fail, truncation marker present). - New test: two back-to-back 60MB status lines from the same worker, which exercises the cursor, the amortized compaction, and appending to a partially-sent backlog. Asserts both 60MB names arrive byte-intact, no worker is marked "crashed", and the run beats a 60s kill. On unfixed macOS x64 the drain alone exceeds the kill; passes in ~6s fixed (debug, Linux). Also ran the whole suite with the 8KB-buffer build so every frame goes through the chunked path: no new failures. - `bun bd test test/cli/test/parallel.test.ts`: failure set identical to the unfixed baseline on this machine (two scheduling-sensitive tests that already fail locally under debug ASAN, unrelated). Note for review: the quadratic is only observable with small socket buffers, so on Linux both the existing test and the new one pass with or without the fix; the lanes that prove the fix are the darwin x64 ones, where the existing `>64MB result line` test stops flaking. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Three distinct failure modes, each with a verified cause. This PR is test-only; the code paths the tests pin are unchanged and still covered (see Verification). ## 1. GC churn test answered by a foreign server `request on a connection surviving graceful stop() never reaches a collected handler` failed with ``` FAIL fetch round 11: bad initial response [{"status":200,"body":"\n \...//x/-/static/main.55cdd4aea43adabcb109.js\">..."}] ``` That body is a verdaccio web UI page; the `routes` variant got verdaccio's 404 `{"error":"no such package available"}`. A freshly dialed connection to the fixture's own freshly bound port was answered by an npm test registry. Cause, reproduced on a macOS 14 CI host: the ephemeral port allocator on macOS honors only exact-address conflicts. A wildcard `Bun.serve({ port: 0 })` bind gets handed a port that another process already holds at `127.0.0.1` (one collision per ~16,384 binds, i.e. once per wrap of the ephemeral range; a loopback-bound holder under both a real node and a bun process, same result). Connects to `127.0.0.1:port` then reach the more specific foreign listener. The churn fixture performs hundreds of wildcard binds per run, so it finds such a port regularly, and leaked verdaccio processes supply the listeners: `VerdaccioRegistry.stop()` calls `kill(0)`, which is a liveness probe rather than a kill (regressed in #16540; fix open in #36352). Fix: bind the fixture's servers (and decoys) to `127.0.0.1`, the address the parks dial. Verified on the same host: 36,000 loopback-bound port-0 binds against a live loopback holder, zero collisions. This protects the test regardless of what else leaks on the machine; #36352 independently removes the main leak source. ## 2. Parse-window test 90s timeout (the build 90105 red) ``` ✗ server.stop() drain promise counts open connections > a response completing inside another socket's parse window still closes its drained connection [90001.99ms] ^ this test timed out after 90000ms. ``` The fixture wrote a partial request head on connection A and waited 20 `setImmediate` ticks before `stop(false)`. A partial head gives the server nothing observable, and on a loaded darwin host those ticks can elapse before the server has even accepted the socket. Verified on a macOS 14 CI host: when `stop(false)` runs while a handshake-completed connection is still waiting in the accept queue, macOS strands it - never accepted, never counted, never closed, and the client side stays silently open. (Linux keeps the pending accept, which is why this never fired there.) In the fixture that means `/poke` never dispatches, `releaseB` never resolves, B stays parked, and `while (!a.closed || !b.closed)` spins until the test timeout with no other output - exactly the observed signature. Fix: A's poke is now a `POST` with a held body. The handler's dispatch is awaited before `stop()` (so the sweep provably sees a busy connection), and writing the 2-byte body afterwards completes the request. The body's fin chunk is delivered inside A's parse window, so B's completion still runs in that window's microtask drain - the per-socket close-gate property the test exists to pin is exercised exactly as before. ## 3. Mid-request sparing test resolving early Build [89946](https://buildkite.com/bun/bun/builds/89946) hit `error: stop() resolved while a mid-request connection was open` in `a connection mid-request survives stop() until the client closes`. Same root cause: the connection's partial head had not reached the server when `stop()` ran, so the server (correctly) had nothing to count and the drain promise resolved. Fix: the mid-request state is staged as a partial second head on a keep-alive connection that already completed a full request, so the server demonstrably owns the socket. If the sweep still closes it, the head had not arrived and the connection was legitimately idle - that round proves nothing about sparing, so it is voided and retried on a fresh server (bounded, fails loudly if every round races). A resolution while the socket is left open is still reported as the bug it would be. Confirmed-spared rounds run in two variants, and the test requires one success of each: - destroy: the client hangs up and that resolves the drain (the original assertion). - complete: the client finishes the head after `stop()`. The request must still dispatch and be answered, which requires the close-when-idle mark to survive the dispatch's response-state reset (`HTTP_CONNECTION_SCOPED` in uWS `HttpResponseData.h`), and the mark must then close the served connection. This preserves the dispatch-after-stop coverage the old parse-window staging provided incidentally (its partial head completed after `stop()`), which the redesign in section 2 otherwise moves ahead of the stop. ## Verification - `bun bd test test/js/bun/http/bun-server.test.ts`: 74 pass / 3 fail, the 3 failures (`parse source map and fetch small stream`, `rejected promise handled by error method`, `abrubtly close a upload request`) fail identically on an unmodified checkout in this environment. - Drain block run 5x, churn test 2x locally: all pass. - Both redesigned fixtures extracted and run 30x on a macOS 14 CI host under the exact canary from build 90105 (`89d30ad11`): 60/60 pass, plus 40x under a 14-way CPU-spin load: all pass. - Coverage check for the parse-window test: patching the `internalEnd` close gates back to the context-wide `isParsingHttp` bit (the bug #37074 guards against) makes the redesigned test fail by timeout, and restoring the per-socket gate makes it pass. - Coverage check for the mid-request test's complete variant: dropping `HTTP_CLOSE_WHEN_IDLE` from `HTTP_CONNECTION_SCOPED` (so the mark is wiped when the post-stop request dispatches) makes it fail by timeout; restored, it passes. The updated fixture also runs 30/30 on the macOS 14 CI host under the build 90105 canary, and hangs as expected under a pre-#37074 build. The remaining hazard - any long-running wildcard port-0 listener on darwin CI can have its loopback traffic stolen by a later explicit `127.0.0.1` bind such as `VerdaccioRegistry`'s `randomPort()` (range 1024-65535 overlaps the kernel's ephemeral range) - is worth addressing in the harness separately; noted on #36352. --- **no test proof** · iteration 0 · Platform-specific test-only change; deferring to CI. --- test/js/bun/http/bun-server.test.ts | 199 ++++++++++++++++++++++------ 1 file changed, 155 insertions(+), 44 deletions(-) diff --git a/test/js/bun/http/bun-server.test.ts b/test/js/bun/http/bun-server.test.ts index d45f7f3913e5..68b4af62e10f 100644 --- a/test/js/bun/http/bun-server.test.ts +++ b/test/js/bun/http/bun-server.test.ts @@ -601,10 +601,10 @@ describe.concurrent("server.stop() drain promise counts open connections", () => // The drain promise must not resolve while a connection is still open, and // a graceful stop() must actively drain: idle keep-alive connections close // right away, busy ones close as soon as their in-flight work completes. - // The client never hangs up first (except in "partial" mode), so every - // observed close below is server-initiated; idleTimeout is long enough that - // a timeout-driven close would flake the runtime budget long before firing. - async function runDrainFixture(mode: "idle" | "inflight" | "inflightHead" | "force" | "partial") { + // The client never hangs up first, so every observed close below is + // server-initiated; idleTimeout is long enough that a timeout-driven close + // would flake the runtime budget long before firing. + async function runDrainFixture(mode: "idle" | "inflight" | "inflightHead" | "force") { await using proc = Bun.spawn({ cmd: [ bunExe(), @@ -637,23 +637,12 @@ describe.concurrent("server.stop() drain promise counts open connections", () => c.on("connect", resolve); c.on("error", reject); }); - if (mode === "partial") { - // Half a request head: enough to be accepted and parsed as an - // in-progress request (a zero-byte connection would sit in the - // TCP_DEFER_ACCEPT queue on Linux and never reach the server), - // never completed. - c.write("GET /slow HTTP/1.1\\r\\nHost: x\\r\\n"); - // Wait until the server has accepted it (it shows up in - // pendingRequests only once parsed, so poll a tick batch). - for (let i = 0; i < 20; i++) await new Promise(r => setImmediate(r)); + const method = mode === "inflightHead" ?

Updates c-ares to v1.34.8. Compare: https://github.com/c-ares/c-ares/compare/3ac47ee46edd8ea40370222f91613fc16c434853...c7a3138dcfe3bb0eaaf10c0c24c36dc66dc790ab ### Compatibility patch v1.34.8 started rejecting DNS name compression pointers inside RDATA for non-RFC1035 types (c-ares/c-ares#1190, per RFC 3597). That is correct for writers, but a lot of deployed resolvers and caches (older BIND, dnsmasq, mDNSResponder on macOS, assorted corporate forwarders) still compress SRV/NAPTR targets, so `dns.resolveSrv()` would fail with `EBADRESP` against them. In CI this showed up as `node-dns.test.js` and `mongodb.test.ts` failures on macOS. `patches/cares/accept-rdata-compression.patch` keeps the parser lenient (always follows compression in RDATA) while the writer stays RFC-strict via `ares_dns_rec_allow_name_comp`. ### Other changes - `test/js/node/process/process.test.js`: expected `process.versions.ares` hash updated - `test/js/node/dns/node-dns.test.js`: new local-UDP-server test that serves a compressed SRV target so this regression is caught without depending on a specific upstream resolver Note: the weekly update workflow force-pushed this branch on Aug 9 and dropped these changes once; they were re-applied in ddb9b5dab9. ## How did you verify your code works? ``` # without patch (c-ares 1.34.8 vanilla) bun bd test test/js/node/dns/node-dns.test.js -t "compressed target" DNSException: querySrv EBADRESP _test._tcp.example.test (fail) dns.resolveSrv accepts compressed target in RDATA # with patch bun bd test test/js/node/dns/node-dns.test.js -t "compressed target" (pass) dns.resolveSrv accepts compressed target in RDATA bun bd test test/js/node/process/process.test.js -t "process.versions" (pass) process.versions ``` Build #87633 (previous full run with these changes) was green on all c-ares-related tests across every lane including macOS.

Every other JS dispatch site in the parser arms the guard, because `rewrite_read` frees streams queued in `pending_engine_stream_closes` only at dispatch depth 0. JS reached from inside that callback (the `Http2Stream` constructor calls `this.on("pause", ...)`, so a patched `EventEmitter.prototype.on` runs there; the handler also calls back into native `rstStream` for refused streams) can close the just-created stream, queueing its deferred free, and then re-enter `parser.read()` at depth 0. The drain frees the box, and the callback return path writes the stream context through the dangling pointer: ``` ==ERROR: AddressSanitizer: heap-use-after-free ... #1 ::set_context src/runtime/api/bun/h2_frame_parser.rs:2110 #2 <...H2FrameParser>::handle_received_stream_id src/runtime/api/bun/h2_frame_parser.rs:5372 #3 <...H2FrameParser>::get_next_stream src/runtime/api/bun/h2_frame_parser.rs:8335 freed by: #12 <...H2FrameParser>::rewrite_read::{closure#3} src/runtime/api/bun/h2_frame_parser.rs:5804 ``` The callers that keep dereferencing the returned pointer (`request()`, `get_next_stream`, the engine HEADERS path) were exposed to the same freed box. ### Fix Arm `enter_dispatch` across the callback, matching the invariant documented on `enter_dispatch` (every section that holds a `Stream` pointer while user JS can run must arm the guard). With the guard armed, the deferred-close drain cannot run while the callback executes, so the pointer stays valid for `set_context` and for the callers. Also skip the context install when the callback closed the stream: `free_resources` already dropped its `sctx` root, and re-inserting one afterwards would pin the dead JS stream object until the session dies. This is the guard-arming fix for the pre-existing issue flagged during review of #37272 (that PR only removes dead code around it). ### Verification New test in `test/js/node/http2/node-http2-streams-rehash.test.ts` (the file covering this class of reentrancy bugs) reproduces the exact sequence: close the new stream and re-enter `read()` from inside the `streamStart` callback. Without the fix it fails on every build tier: heap-use-after-free under the ASAN debug build, and on release builds `getStreamContext(2)` throws "Invalid stream id" because the drain already freed the entry inside the callback. With the fix the entry survives the callback with no context installed (covering the skip-install branch), and a follow-up depth-0 `read()` asserts the deferred close then actually drains. Existing http2 suites (`node-http2.test.js`, `h2-conformance.test.ts`, the staged h2 tests, node's server-push parallel tests) pass with the change. --- **[review]** gate passed · iteration 1 · 2 files touched

Fixes the Linux flake in `test/cli/install/bun-security-scanner-matrix-with-node-modules.test.ts` (9 of the last ~80 main builds), which showed up as an unexpected extra `left-pad` entry in the `requested-packages` snapshot: ``` expect(sortedPackages).toMatchSnapshot(`requested-packages: ${key}`) - [] + [ "left-pad" ] ✗ bun install > no args > --linker=isolated > (scanner: npm.bunfigonly) > (bun.lock exists: false) > ... > 0057 (with modules) ``` **Cause:** the "with modules" scenarios run a setup `bun install`, clear the registry request log, then assert the exact set of manifests the command under test requests. With the manifest cache on, that set depended on whether the setup install's asynchronous cache writes had reached disk before it exited. `bun install` deliberately does not wait for those writes (they are atomic-rename; a missing entry just means a refetch), so the asserted set was a race outcome, not a property of the command. **Fix (test-only):** disable the manifest cache for both installs in the matrix runner so the install under test always fetches its manifests, and regenerate the affected snapshots (the affected "with modules" scenarios, mostly the no-lockfile ones, now list the manifests they fetch). An install-side wait for the pending cache writes (`pending_manifest_saves`) was tried on this branch first and reverted in favor of keeping the cache write fire-and-forget. The reproduction numbers for the underlying write race are in the comments below. ### How did you verify your code works? Test-only change: the with-modules scanner matrix runs with the regenerated snapshots in CI on all lanes. --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: robobun <117481402+robobun@users.noreply.github.com> --- ...nner-matrix-with-node-modules.test.ts.snap | 1354 +++++++++++++++-- .../bun-security-scanner-matrix-runner.ts | 10 +- 2 files changed, 1210 insertions(+), 154 deletions(-) diff --git a/test/cli/install/__snapshots__/bun-security-scanner-matrix-with-node-modules.test.ts.snap b/test/cli/install/__snapshots__/bun-security-scanner-matrix-with-node-modules.test.ts.snap index 5e1280a3520a..22a81f3fa5d6 100644 --- a/test/cli/install/__snapshots__/bun-security-scanner-matrix-with-node-modules.test.ts.snap +++ b/test/cli/install/__snapshots__/bun-security-scanner-matrix-with-node-modules.test.ts.snap @@ -20,23 +20,43 @@ exports[`bun install no args --linker=hoisted (scanner: local) (bun.lock exists: exports[`bun install no args --linker=hoisted (scanner: local) (bun.lock exists: true) (advisories: fatal) (no-TTY) 0005 (with modules): requested-tarballs: install without args 1`] = `[]`;

Registers the default `'warning'` printer when `process` is created, the way Node's bootstrap does (`lib/internal/process/pre_execution.js` `setupWarningHandler`), instead of on the first `emitWarning()`. #31831 made the printer a real `'warning'` listener but installed it lazily, which its description called out as a divergence: `process.removeAllListeners('warning')` at startup did not silence it. That idiom is how programs (CLIs rendering a TUI, test runners) opt out of the default print, and it silenced warnings on every Bun release before #31831 (a user listener suppressed the native print), so this is a regression for them: ```js process.removeAllListeners("warning"); process.on("warning", w => console.log("user listener got:", w.name)); process.emitWarning("hello"); ``` | runtime | stderr | |---|---| | node v26.3.0 (and v24.18.0) | (nothing) | | bun 1.4.0-canary (before #31831) | (nothing) | | bun main | `(node:PID) Warning: hello` + `(Use \`bun --trace-warnings ...\`)` | | this PR | (nothing) | **The fix** is `Process::installDefaultWarningListener`, called from `Process::finishCreation`. To keep the printer's setup (`--redirect-warnings`, `--disable-warning`, `require("node:fs")`) off the startup path, what gets registered up front is a native `onWarning` stub; `Process::ensureOnWarning` builds the JS printer (`createOnWarning`, the former `installOnWarningListener` minus the `prependListener` call) on the first warning and the stub forwards to it. Startup cost is one native `JSFunction` and one listener-map entry per `process` object; the listener is added before `onDidChangeListener` is wired so it does not trigger the signal-table loading that hook does on every add. Observable results, all matching Node (every script in the tests, plus the extra probes listed under verification, was run under node v26.3.0 and v24.18.0 and prints byte-identical output modulo pid/argv0): - `process.listenerCount('warning')` is `1` at startup, `process.listeners('warning')[0].name === 'onWarning'`, and removing it by reference or via `removeAllListeners` silences the print. - `--no-warnings` / `NODE_NO_WARNINGS=1` register nothing (`listenerCount === 0`); user listeners still fire. - Each `worker_threads` Worker gets its own listener. - Print-before-user-listener ordering is unchanged. - A bare `process.emit('warning', err)` with no prior `emitWarning()` now prints, as in Node (the other divergence #31831's description listed). The printer no longer reads `process.noProcessWarnings` at all (Node's doesn't; it is only a read-only alias of the flag). `test/js/node/test/common`, which used that read to apply a test's `--no-warnings` flag in-process, now removes the bootstrap listener instead — it loads before any test listener exists, so that is the same state the flag produces. ### How did you verify your code works? New `describe("default 'warning' listener is registered at startup")` block in `test/js/node/process/process.test.js` (8 cases). On the unfixed build the `removeAllListeners`-before-first-warning cases print the warning, `listenerCount` is `0`, the worker case reports `0:1`, and the bare-`emit` case prints nothing; all pass with `bun bd test`. Node's own suite has no test for the startup listener (which is how #31831 missed it), so these are hand-written; the existing warning-pipeline tests (`test-process-warning*.js`, `test-process-warnings.mjs`, `test-process-emitwarning.js`, `test-env-var-no-warnings.js`, `test-process-redirect-warnings*.js`, `test-common-expect-warning.js`, the max-listeners and timers warning tests) still pass. Beyond the test scripts, these were also diffed against node v26.3.0 and v24.18.0 on the built binary and came out identical: no-arg `removeAllListeners()`, the `--trace-warnings` hint printed once across two warnings, calling `process.listeners('warning')[0]` directly with an Error and with a non-Error, `--trace-warnings` stacks, `--redirect-warnings` / `NODE_REDIRECT_WARNINGS`, and `--disable-warning`. The new native path was also exercised under `BUN_JSC_validateExceptionChecks=1`. --------- Co-authored-by: Dylan Conway --- .buildkite/ci.mjs | 11 ++- src/js/builtins/ProcessObjectInternals.ts | 15 ++-- src/jsc/bindings/BunProcess.cpp | 75 ++++++++++------ src/jsc/bindings/BunProcess.h | 8 +- test/js/node/process/process.test.js | 101 ++++++++++++++++++++++ test/js/node/test/common/index.js | 7 +- 6 files changed, 172 insertions(+), 45 deletions(-) diff --git a/.buildkite/ci.mjs b/.buildkite/ci.mjs index 54fe447ffad0..8af4d676ef31 100755 --- a/.buildkite/ci.mjs +++ b/.buildkite/ci.mjs @@ -186,9 +186,11 @@ const testPlatforms = [ // The darwin test suite runs on real macOS agents against the Linux-built // artifacts from the `darwin--build-bun` steps (the only darwin build // lanes — see buildPlatforms). - { os: "darwin", arch: "aarch64", release: "26", tier: "latest" }, - { os: "darwin", arch: "aarch64", release: "14", tier: "previous" }, - { os: "darwin", arch: "x64", release: "14", tier: "latest" }, + // The macOS test agents are offline; darwin still builds (cross-compiled on + // Linux) but isn't tested until they're back. + // { os: "darwin", arch: "aarch64", release: "26", tier: "latest" }, + // { os: "darwin", arch: "aarch64", release: "14", tier: "previous" }, + // { os: "darwin", arch: "x64", release: "14", tier: "latest" }, { os: "linux", arch: "aarch64", distro: "debian", release: "13", tier: "latest" }, { os: "linux", arch: "x64", distro: "debian", release: "13", tier: "latest" }, { os: "linux", arch: "x64", profile: "asan", distro: "debian", release: "13", tier: "latest" }, @@ -756,7 +758,8 @@ function getVerifyBaselineStep(platform, options) { * traces itself; `packageAndUpload()` is its sole publisher. */ const traceOrderTargets = [ - { os: "darwin", arch: "aarch64", on: { os: "darwin", arch: "aarch64", release: "26", tier: "latest" } }, + // Runs on the macOS test agents, which are offline (see testPlatforms). + // { os: "darwin", arch: "aarch64", on: { os: "darwin", arch: "aarch64", release: "26", tier: "latest" } }, { os: "linux", arch: "x64", on: { os: "linux", arch: "x64", distro: "debian", release: "13" } }, ]; diff --git a/src/js/builtins/ProcessObjectInternals.ts b/src/js/builtins/ProcessObjectInternals.ts index 84f559291595..5373569f51cb 100644 --- a/src/js/builtins/ProcessObjectInternals.ts +++ b/src/js/builtins/ProcessObjectInternals.ts @@ -632,9 +632,10 @@ export function rawDebug() { } catch {} } -export function installOnWarningListener(process, redirectPath, disabledArr) { - // Port of https://github.com/nodejs/node/blob/main/lib/internal/process/warning.js onWarning, - // registered as a real 'warning' listener so removeAllListeners('warning') silences it. +// Port of https://github.com/nodejs/node/blob/main/lib/internal/process/warning.js onWarning. +// The 'warning' listener itself is a native trampoline registered when `process` is created +// (BunProcess.cpp); this builds the printer it forwards to on the first warning. +export function createOnWarning(process, redirectPath, disabledArr) { const appendFileSync = redirectPath ? require("node:fs").appendFileSync : undefined; // --disable-warning names/codes as a Set: matches Node's SafeSet lookup // and avoids an FFI + utf8() encode per emit. @@ -658,7 +659,7 @@ export function installOnWarningListener(process, redirectPath, disabledArr) { process.stderr.write(message + "\n"); } - function onWarning(warning) { + return function onWarning(warning) { if (!(warning instanceof Error)) return; const name = warning.name || "Warning"; const isDeprecation = name === "DeprecationWarning"; @@ -689,11 +690,7 @@ export function installOnWarningListener(process, redirectPath, disabledArr) { `(Use \`${basename(process.argv0 || "node")} --trace-warnings ...\` to show where the warning was created)`, ); } - } - - // prependListener: user listeners added before the first emitWarning must - // still fire *after* the print, matching Node's bootstrap ordering. - process.prependListener("warning", onWarning); + }; } export function loadEnvFile(path) { diff --git a/src/jsc/bindings/BunProcess.cpp b/src/jsc/bindings/BunProcess.cpp index ce39ea85cff8..cac125f29df3 100644 --- a/src/jsc/bindings/BunProcess.cpp +++ b/src/jsc/bindings/BunProcess.cpp @@ -47,6 +47,7 @@ #include #include "wtf-bindings.h" #include "EventLoopTask.h" +#include "JSEventListener.h" #include #include @@ -1690,27 +1691,15 @@ Process::~Process() extern "C" bool Bun__NODE_NO_WARNINGS(); -// Install the JS onWarning listener (once per Process).

Stopgap while the bare-metal macOS test fleet (`test-darwin` queue) is offline being reimaged. - Darwin test steps now target a `test-darwin-hosted` queue backed by Buildkite-hosted M4 agents, instead of selecting fleet agents by `os`/`arch`/`release-tier` tags. - Only the aarch64 `latest` (macOS 26) lane runs there. Hosted agents are Apple Silicon only and the queue is pinned to a single image, so the aarch64 `previous` and the x64 lanes are dropped until the fleet returns. - Darwin tests run on `main`, or on a PR when the commit subject contains `[macos tests]`. Other PR pushes skip them, to bound hosted-agent spend. Darwin **build** lanes are unaffected (they cross-compile on Linux), so PRs still prove darwin compiles. Needs the `test-darwin-hosted` queue to exist in the `CI` cluster before merge (Buildkite hosted, `MACOS_ARM64_M4_6X28`, macOS 26 image). Until it does, darwin test jobs on main will wait for an agent, which is no worse than today.

This puts the entries back. #37354's filter still drops the two lanes hosted agents can't run (aarch64 `previous`, x64) and gates the rest to `main` / `[macos tests]`, so the effective result is one aarch64 macOS 26 lane on `test-darwin-hosted`, which build 91720 already showed passing in ~13 min.

Darwin test steps were pinned to `parallelism: 2` because the bare-metal fleet only had a couple of boxes per lane. On the Buildkite-hosted queue from #37354 every shard gets its own M4 agent, so widen darwin to 10 shards. Expected effect per main build: the ~26 min darwin suite (2 × 13 min on hosted today, build 91720) becomes ~26/10 + ~2 min per-shard setup ≈ 4-5 min wall clock, for roughly +30% billed minutes (each shard repeats checkout / artifact download / `bun install`). Not going wider than 10 because beyond that the fixed setup dominates. Revisit together with the #37354 revert once the fleet is back (the fleet can still absorb 10 queued shards per lane, it just serializes them). ### How did you verify your code works? `node --check`; the value only feeds the step's `parallelism` field, and `runner.node.mjs` already shards by `BUILDKITE_PARALLEL_JOB`/`_COUNT` (linux runs 20-wide the same way). --- .buildkite/ci.mjs | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/.buildkite/ci.mjs b/.buildkite/ci.mjs index 0d81807631a2..4daa740de8da 100755 --- a/.buildkite/ci.mjs +++ b/.buildkite/ci.mjs @@ -864,7 +864,11 @@ function getTestBunStep(platform, options, testOptions = {}) { agents: getTestAgent(platform, options), retry: getRetry(), cancel_on_build_failing: isMergeQueue(), - parallelism: os === "darwin" ? 2 : os === "windows" ? 8 : 20, + // darwin: 10 while on hosted agents (see darwinHostedQueue), which scale + // one agent per shard; it was 2 for the bare-metal fleet's few boxes per + // lane.

Adds `BUN_FEATURE_FLAG_DISABLE_STANDALONE_MADVISE`, a runtime opt-out for the behavior introduced in #29320: a `bun build --compile` executable calls `madvise(MADV_DONTNEED)` on its embedded source section once the entrypoint has loaded, so anything that touches the source afterwards (a lazy `require()`, resolving a stack trace) pages it back in from the executable on disk. Deployments where that re-read is undesirable can set the flag in the environment of the running executable to keep the pages resident: ```sh BUN_FEATURE_FLAG_DISABLE_STANDALONE_MADVISE=1 ./myapp ``` The compiled binary reads it at runtime, nothing is baked in at compile time. It follows the existing `BUN_FEATURE_FLAG_DISABLE_*` escape hatches: registered in `env_var.rs`, checked in `hint_source_pages_dont_need()` (which returns early, sharing the existing `len == 0` return), falsy values such as `0` keep the default. No effect on Windows or on the plain interpreter, which never issue the hint. Like the other `BUN_FEATURE_FLAG_DISABLE_*` escape hatches it is not documented. #37356 is the alternative of removing the madvise call altogether; the two are mutually exclusive. ### How did you verify your code works? `test/js/bun/compile/standalone-madvise-tla.test.ts` now runs the same compiled binary three times with `BUN_DEBUG_StandaloneModuleGraph=1`: with the variable unset (explicitly removed from the child env so an ambient value on the host cannot leak in), set to `0`, and set to `1`. The first two must log a `hintSourcePagesDontNeed:` line, the last must not log one at all, since the flag path returns before logging anything. The test stays debug-only because it relies on the scoped logger. Against a debug build without this change the `1` case fails as expected: ``` Expected to not contain: "hintSourcePagesDontNeed:" Received: "before-await\nafter-await\n[standalonemodulegraph] hintSourcePagesDontNeed: MADV_DONTNEED 4096 bytes\n" ``` With the change, `bun bd test test/js/bun/compile/standalone-madvise-tla.test.ts` passes (22 assertions). --- **no test proof** · iteration 1 · Platform-specific test(s) that do not run on this machine.

Every compile copies and rewrites the whole bun binary, which is about 1 GB with a debug+ASAN build and takes roughly 2.5s there (every single-compile test in the file reports 2.4s to 2.9s), so the test needed 7s or more of a 5s default per-test budget. On the unmodified file, `bun bd test test/bundler/bun-build-compile.test.ts` at 9fcdea80b1: ``` (fail) Bun.build compile > compile with relative outfile paths [5523.70ms] ^ this test timed out after 5000ms. (pass) Bun.build compile > compile with embedded resources uses correct module prefix [5227.91ms] ``` The failure is intermittent (the session that reported it saw it in about 1 run in 3, with the passing runs taking 7.0s to 7.2s). The compile step runs on the JS thread inside the bundle completion task (`do_compilation` is called from `JSBundleCompletionTask::on_complete`), so the timeout can only be observed between compiles: when the first two compiles add up to more than 5s the test fails after the second one, otherwise the third compile starts and the test finishes late but passes. The third compile of a timed-out run also keeps going and slows down the next test, which is why "embedded resources" shows 5.2s above and 2.5s once this is fixed. This only affects the 5s default used by a plain `bun test` / `bun bd test` run; the CI runner passes a much larger `--timeout`, and with a release binary each compile takes about 0.13s. ### Fix Turn the three cases into a `test.each`, so every test does exactly one compile, the same shape as the rest of the file. The per-test timeout is left at the default rather than raised: the workload per test is what was out of proportion. While rewriting the assertion, the three `toContain` / `toEndWith` checks on the reported path become an exact comparison against the outfile that was passed in (`.exe` appended on Windows; with no `outdir` the artifact path is the outfile verbatim), and each case also checks that the executable exists at that path, which is what the nested `output/nested/` and `a/b/c/d/` cases are there to prove. Nothing else in the file changes. ### Verification `bun bd test test/bundler/bun-build-compile.test.ts` (debug+ASAN), two runs, 14 pass / 1 skip each, about 40s per run: ``` (pass) Bun.build compile > compile writes the executable to outfile output/nested/app1 [2567.03ms] (pass) Bun.build compile > compile writes the executable to outfile app2 [2576.66ms] (pass) Bun.build compile > compile writes the executable to outfile a/b/c/d/app3 [2590.81ms] (pass) Bun.build compile > compile with embedded resources uses correct module prefix [2501.16ms] ``` The same file also passes with a release bun on Linux (`USE_SYSTEM_BUN=1`) and on Windows Server 2019 x64 (release bun 1.4.0, where the exact path assertion exercises the `.exe` branch). Related: #37389 raises this test's timeout to 60s as a side change of an unrelated fix; whichever lands second drops or rebases a one-line hunk. #37397 fixes the neighbouring "embedded resources" test in the same file and does not overlap with this hunk. --- test/bundler/bun-build-compile.test.ts | 50 ++++++++++---------------- 1 file changed, 18 insertions(+), 32 deletions(-) diff --git a/test/bundler/bun-build-compile.test.ts b/test/bundler/bun-build-compile.test.ts index 6d6c2055012f..3020baa43de3 100644 --- a/test/bundler/bun-build-compile.test.ts +++ b/test/bundler/bun-build-compile.test.ts @@ -50,41 +50,27 @@ describe("Bun.build compile", () => { }), ).toThrowErrorMatchingInlineSnapshot(`"Unknown compile target: bun-invalid-platform"`); }); - test("compile with relative outfile paths", async () => { - using dir = tempDir("build-compile-relative-paths", { - "app.js": `console.log("Testing relative paths");`, - }); - // Test 1: Nested forward slash path - const result1 = await Bun.build({ - entrypoints: [join(dir + "", "app.js")], - compile: { - outfile: join(dir + "", "output/nested/app1"), - }, - }); - expect(result1.success).toBe(true); - expect(result1.outputs[0].path).toContain(join("output", "nested", isWindows ?

Current output: ``` Bailed out after 1 failure b.test.js: ✗ b.test.js (aborted: sibling worker panicked) ``` No worker panicked. Reproduces 15/15 runs with the added test against the current release. ### Cause `Coordinator.bailed: bool` covered both "stopped by `--bail=N`" and "stopped because a worker panicked", so `reap_worker` could not tell them apart and reported every post-stop mid-file death as collateral of a panic. After a plain bail such a death is a crash of that file and should go through `account_crash` (crash line, `crashed_files`, timing). ### Fix `bailed` becomes `stop_reason: Option` with `Bail` and `WorkerPanicked`. Only `WorkerPanicked` turns sibling deaths into "aborted: sibling worker panicked". `abort_on_worker_panic` still upgrades a `Bail` stop to `WorkerPanicked` so the workers it terminates are reported exactly as before, and still only sweeps the queued files when the panic is what stopped the run. All other uses of the flag are unchanged (`is_some()` / `is_none()`). ### Tests `test/cli/test/parallel.test.ts`: "a worker that dies mid-file after the bail is reported as a crash". The fixture sequences the two workers through files on disk (b waits for a's worker to be gone, which only happens after the bail), so it does not depend on timing. Fails on the current release with the output above, passes with this change; the existing bail and panic tests still pass. --- src/runtime/cli/test/parallel/Coordinator.rs | 49 +++++++++++------ src/runtime/cli/test/parallel/runner.rs | 2 +- test/cli/test/parallel.test.ts | 58 ++++++++++++++++++++ 3 files changed, 91 insertions(+), 18 deletions(-) diff --git a/src/runtime/cli/test/parallel/Coordinator.rs b/src/runtime/cli/test/parallel/Coordinator.rs index a43d8b297698..c68a8df2d9c2 100644 --- a/src/runtime/cli/test/parallel/Coordinator.rs +++ b/src/runtime/cli/test/parallel/Coordinator.rs @@ -59,7 +59,7 @@ pub struct Coordinator<'a> { pub(crate) live_workers: u32, pub(crate) crashed_files: Vec, pub(crate) aborted: Option, - pub(crate) bailed: bool, + pub(crate) stop_reason: Option, pub(crate) last_printed_dot: bool, /// Kill-on-close Job Object so the OS reaps workers if the coordinator dies /// without running its signal handler (e.g. SIGKILL / TerminateProcess). @@ -67,9 +67,21 @@ pub struct Coordinator<'a> { pub(crate) windows_job: Option<*mut c_void>, } +/// Why the run stopped dispatching files.

Node.js dns.lookup, same host -> 13.32.104.65 ``` macOS, Windows, and Android already default to the system backend; Linux was the only platform defaulting to c-ares, and `src/js/node/dns.ts` never set `backend`, so `node:dns.lookup` inherited it. ### Fix `translateLookupOptions` now passes `backend: "system"`, so both `dns.lookup` and `dns.promises.lookup` (and therefore `net.connect` hostname resolution, which goes through `dns.lookup`) resolve via the platform resolver, matching Node's contract. On Linux that is `getaddrinfo(3)` on a worker thread, which is also how Node itself implements `lookup`. On macOS/Windows/Android this is a no-op since the system backend was already the default. `Bun.dns.lookup()`'s default backend is deliberately unchanged (c-ares stays the Linux default there, with real TTLs and in-event-loop async resolution); the `backend` option is now documented on the DNS docs page, which previously didn't mention it. ### Test The new test mirrors the report without needing a VPN: it points `dns.setServers` at a local UDP responder that REFUSEs every query, then looks up `127.1`. `getaddrinfo` resolves that legacy IPv4 literal locally with no DNS traffic, while c-ares treats it as a hostname and queries the refusing server, so before this change the lookup failed with `EREFUSED` and now it returns `127.0.0.1`. Verified failing on the released build and passing with this change; the rest of `node-dns.test.js` and the `node-net` suite show no new failures. --- **no test proof** · iteration 2 · Platform-specific test(s) that do not run on this machine.

Both build-cpp and build-bun are on the build's critical path, so this is ~30s of wall clock per build plus ~13 agent-minutes. It is `findRustLld()` in `tools.ts`. After pre-flighting `rustup toolchain install `, it runs `rustc --print sysroot` and `rustc -vV`. `rustc` is the rustup proxy, the cwd is the repo root, and a proxy invoked there applies `rust-toolchain.toml` in full: not just the channel, but installing every `components` and `targets` entry that is missing (rustfmt, clippy, miri, llvm-tools, and `rust-std` for ten cross targets). The probe's stderr is piped and discarded, so nothing shows in the log. The images have the channel but not that list, so every job downloads ~1.7 GB and installs it into an instance that is thrown away a few minutes later. Reproduced here with a fresh `RUSTUP_HOME`: | step | time | toolchain dir | |---|---|---| | pre-flight `rustup toolchain install --profile minimal --component rust-src` | 16s | 663 MB | | `rustc --print sysroot` with `RUSTUP_TOOLCHAIN=` (this PR) | 17ms | 663 MB | | `rustc --print sysroot` in the repo root without it (main) | 36s ("downloading 14 components") | 2.4 GB | ### Change - The two rustc probes run with `RUSTUP_TOOLCHAIN` set to the channel the pre-flight just ensured, so the proxy resolves the toolchain and nothing else. The build itself installs what it needs (`rust-src` in the pre-flight, the target's `rust-std` in the `rust_build_cross` rule), and `rust-toolchain.toml` still applies to anyone running cargo/clippy/rustfmt directly, which is what its component list is for. The visible behaviour change for developers is that `bun bd` after a channel bump no longer also downloads those ~1.7 GB; the first direct `cargo clippy` etc. does, with rustup's normal output. - The pre-flight prints how long it took when that was 5s or more (it runs with `-q`, which also hides download progress), so an image missing the channel itself shows up as a line in the configure group instead of as silent time. Locally it stays silent (~0.4s). If this PR's own CI run still shows a multi-second configure, that line will say why; the remaining fix in that case is baking the pinned channel into the images in `bootstrap.sh`, which I have left out of this PR because it needs an image rebuild to verify. ### Test `test/internal/build-rust-toolchain-probe.test.ts` points `CARGO_HOME` at a directory whose `bin/rustc` is a script that reports the `RUSTUP_TOOLCHAIN` it received as its sysroot (PATH is emptied so no real rustup pre-flight runs) and checks `findRustLld()` returns the channel from `rust-toolchain.toml`. On main it returns `unset`. --- scripts/build/tools.ts | 35 +++++++++--- .../build-rust-toolchain-probe.test.ts | 54 +++++++++++++++++++ 2 files changed, 83 insertions(+), 6 deletions(-) create mode 100644 test/internal/build-rust-toolchain-probe.test.ts diff --git a/scripts/build/tools.ts b/scripts/build/tools.ts index 5bd38265c25f..7b22495a6665 100644 --- a/scripts/build/tools.ts +++ b/scripts/build/tools.ts @@ -658,36 +658,59 @@ export function findRustLld(os: OS): { // and the silent failure leaves `rustLld` undefined, which falls back to the // system lld.

Fixes a data race on `ThreadSafeStreamBuffer.callback` (the streaming request body's drain callback) between the HTTP thread and the JS thread. **Cause.** The HTTP thread reads `callback` in `report_drain()` while holding the buffer mutex (`src/http/lib.rs` `write_to_stream`, and the h2/h3 `drain_send_body`). The JS thread cleared it in `clear_drain_callback()` without the mutex; the comments in `FetchTasklet` claimed the field was main-thread-only. `FetchTasklet::start_request_stream` calls `clear_sink()` when `assign_to_stream` fails, and at that point the request is still in flight: the HTTP thread still owns its ref on the buffer and may be flushing the bytes that were just written, so the unlocked write of `None` raced the locked read. `Option` is two words (fn pointer + context), so a stale or torn read calls `on_write_request_data_drain(tasklet)` during teardown. Today the tasklet is still referenced on that path (the HTTP side releases its ref only after the abort completes), so the worst case is a spurious resume task, but nothing in the code enforces that. The other caller, `deinit` -> `clear_data` -> `clear_sink`, is already ordered after the HTTP thread's last access by the tasklet refcount release. A user-reachable way onto that path is a direct stream request body whose `pull()` writes and then throws synchronously: ```ts await fetch(url, { method: "POST", body: new ReadableStream({ type: "direct", pull(controller) { for (let i = 0; i < 4; i++) controller.write(chunk); // wakes the HTTP thread throw error; // assign_to_stream fails -> write_end_request -> clear_sink }, }), }); ``` **Fix.** `clear_drain_callback` takes the buffer mutex, so it is serialised against `report_drain`; once it returns the HTTP thread can no longer call back into the tasklet through the buffer. The field is now private so every access goes through the locked accessors, and `report_drain` debug-asserts that the caller holds the lock (it already had to, per its doc comment). The stale comments in `FetchTasklet` are corrected. ### How did you verify your code works? New test in `test/js/web/fetch/fetch-abort-stream-body.test.ts` drives the snippet above 50 times against a server that does not answer until the upload is torn down, and checks that every fetch rejects with `pull()`'s own error, that `pull()` ran every time (it only runs once the HTTP thread has asked for the body, so the teardown really happens in flight), and, with the fix, that clearing the callback does not deadlock against the HTTP thread holding the buffer. There is no thread sanitizer build, so this test is regression coverage of the path rather than a detector for the race itself; it also passes on the unfixed build. To confirm the window is actually hit, I temporarily logged both accesses in a debug build and ran the same scenario 500 times:
    Observed interleavings (temporary instrumentation, not part of the PR) Per request, in logging order (`drain` = HTTP thread `report_drain`, `clear` = JS thread `clear_drain_callback`): ``` 298 drain > drain > drain > clear 161 drain > drain > clear 28 drain > drain > drain > drain > clear 7 drain > clear 3 clear > drain <- HTTP thread read the field after the JS thread cleared it 3 drain > clear > drain <- same ``` 500/500 requests had the HTTP thread reading the callback in the same window as the JS-side clear; in 6 the read landed after the clear (with the fix it observes `None`; before it was an unsynchronised read of a field being written).
    Also ran under the debug build: `fetch-abort-stream-body.test.ts`, `fetch-http2-client.test.ts`, `fetch-http3-client.test.ts` (their streaming request body tests exercise the new `report_drain` assertion on h1, h2 and h3), `body.test.ts`, `fetch-cyclic-reference.test.ts`, `fetch-keepalive.test.ts`. `fetch-backpressure.test.ts`'s four `h3 receive backpressure` cases time out locally when the whole file runs, identically on unmodified main (they send no request body, so they do not touch this code); they pass in isolation. A larger follow-up could make the mutex own `buffer` and `callback` outright (`Guarded<_>`), which would also remove the `&mut ThreadSafeStreamBuffer` both threads currently hold at once; this PR only closes the race. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

With `BUN_DEBUG_fetch=1` a debug build logs `doRedirect` four times and `Keep-Alive release in redirect` zero times. The same happens for `POST -> 307` (body resent) and `POST -> 303`. The count should stay at 1. ### Cause `do_redirect` only releases the socket to the pool when `request_stage == Done` (gate added in #29766, shipped in 1.3.14, so that a 303 answering a still-uploading streamed POST is not pooled mid-chunked-body). But `on_writable`'s initial-payload arm sets `request_stage = Body` when the headers and the byte body went out in that first write and returns; nothing advances it to `Done` unless a further writable event happens to fire. So for an ordinary GET, or any request that fits in one write, the gate is never true. Before #29766 these connections were pooled. `send_progress_update_without_stage_check` had been working around the same parking with a separate "unsent slice is empty" check for byte bodies. ### Fix * `on_writable`: when the initial write sent both headers and body (only possible for a byte body, see `send_initial_request_payload`), set `request_stage = Done`, which is what the `Body` arm already does for a body that needs more than one write and what `write_to_stream` does for streams. The `is_streaming_request_body` branch that used to sit there was unreachable (`has_sent_body` is never true for a stream body). * Both keep-alive release sites (`do_redirect` and `send_progress_update_without_stage_check`) now gate on one helper, `is_request_fully_sent()` (`request_stage == Done`), so the byte-body special case in the progress-update path goes away. For byte bodies this is the same as the old check whenever the headers had been fully written, and stricter (close instead of pool) if a response completes while the request head itself is still partially unsent, which is the right call for that connection too. Stream and sendfile bodies are unchanged: both already required `Done`. * `do_redirect` forgot `unix_socket_path` before making the pool/close decision, which `is_keep_alive_possible()` reads to keep unix-socket connections out of the pool. That was harmless while the gate never passed; with the gate fixed it would pool the unix connection under the request URL's host:port and the TCP hop to that host:port would be served by the unix server (verified both ways: the new `fetch.unix` test fails with `"unix /world"` instead of `"tcp /world"` if only the gate is fixed). `do_redirect` now takes the keep-alive decision before the path is forgotten. Scope: this only changes bodyless (`Content-Length: 0`) 3xx responses. A 3xx with a body already has `allow_keepalive` cleared in `handle_response_metadata` because the body is discarded rather than read, and `Connection: close` is honoured on any status, so those still close. The proxy-tunnel and TLS Host-override exclusions in `do_redirect` are unchanged. ### Tests `test/js/web/fetch/fetch-keepalive.test.ts`: * `redirect keep-alive:` `GET -> 302`, `POST -> 303`, `POST -> 307`: four redirected fetches use one connection (fail before the fix with 5 connections, on both the release binary and a debug build of main); `302 + Connection: close` and `302 carrying a body` still dial once per fetch. * `a connection answered early (...) is not pooled`: a 303 arriving while a ReadableStream body is still open, a 303 arriving while a 64 MiB byte body is still being written, and a 200 doing the same (the non-redirect release site) all make the next request dial a new connection, and the server confirms nothing was written into the unfinished upload. There was no test for the streamed-303 hazard #29766's gate exists for, nor for the byte-body early-reply check in the progress-update path. The two byte-body cases are skipped on Windows: its loopback accepts the whole 64 MiB into kernel buffers at once even with the peer not reading (checked on a Windows box: after the early reply the server can still read all 64 MiB followed by the next request), so there the request really is fully sent and reuse is legitimate; the scenario only exists where the socket buffers bound the upload. `test/js/web/fetch/fetch.unix.test.ts`: the unix-socket connection whose redirect is being followed is not handed to the TCP hop. Also ran the fetch, client-fetch, fetch-redirect, fetch-tcp-keepalive, proxy (tunnel pooling), node-http, body/stream and a few install suites against the debug build; the remaining failures there reproduce identically on the unmodified binary in this environment (`NO_PROXY`/localhost binding, and ASAN timeouts on tests that are close to 5s on main as well). --- src/http/lib.rs | 63 ++----- test/js/web/fetch/fetch-keepalive.test.ts | 201 +++++++++++++++++++++- test/js/web/fetch/fetch.unix.test.ts | 29 ++++ 3 files changed, 247 insertions(+), 46 deletions(-) diff --git a/src/http/lib.rs b/src/http/lib.rs index 5e27bd2f4e12..0c878cfc9b28 100644 --- a/src/http/lib.rs +++ b/src/http/lib.rs @@ -1586,6 +1586,12 @@ impl<'a> HTTPClient<'a> { !self.request_body().is_empty() } + /// Pooling a socket whose request is still going out would land the next request inside this one's body. + #[inline] + fn is_request_fully_sent(&self) -> bool { + self.state.request_stage == RequestStage::Done + } + #[inline] fn request_body(&self) -> &[u8] { // `request_body` is a `RawSlice` into `original_request_body` (sibling @@ -2577,6 +2583,8 @@ impl<'a> HTTPClient<'a> { self.flags.is_streaming_request_body = false; } + // Decided before unix_socket_path is forgotten below: a unix-socket connection must not be pooled. + let keep_alive_possible = self.is_keep_alive_possible(); // There is no struct copy-back // (`sync_progress_from` skips owned fields) and the original retains // its own `Owned(Vec)` aliasing the same allocation (the HTTP-thread @@ -2612,8 +2620,8 @@ impl<'a> HTTPClient<'a> { bun_core::scoped_log!(fetch, "close the tunnel"); self.close_proxy_tunnel(true); GenHttpContext::::close_socket(socket); - } else if self.state.request_stage == RequestStage::Done - && self.is_keep_alive_possible() + } else if keep_alive_possible + && self.is_request_fully_sent() && !socket.is_closed_or_has_error() // A direct TLS socket verified against a Host-header override // (get_tls_hostname) must not be pooled here: this.url has already @@ -2621,10 +2629,6 @@ impl<'a> HTTPClient<'a> { // can no longer compute the correct pool key.

This needs the connection's receive window to have grown past 64 KiB first, so it shows up on long-lived, chatty connections rather than on the first message. `tls.connect({ socket: duplex })` has the same underlying problem in a milder form: when a `'data'` handler calls `write()` while more ciphertext is queued, the next `'data'` event is emitted nested inside the running handler. Node never does that. ```ts // wss server: on "go" -> ws.ping(); ws.send(Buffer.alloc(128 * 1024)); ws.send("marker"); const ws = new WebSocket(`wss://127.0.0.1:${port}`, { proxy: `http://127.0.0.1:${proxyPort}`, tls: { rejectUnauthorized: false } }); // (proxy releases the burst in a single write) // before: onclose code 1002 after the ping, the 128 KiB message and "marker" never arrive // after: message, "marker" and the pong all delivered ``` ### Cause `SSLWrapper::handle_traffic` (`src/uws/lib.rs`, the in-memory BIO engine used by the WebSocket proxy tunnel, the fetch proxy tunnel, `UpgradedDuplex` and `WindowsNamedPipe`) ran a complete pass every time it was called, and it is called from inside its own callbacks: `write_data()` from `on_data`/`on_handshake`, `receive_data()` from a peer that answers synchronously, `flush()`. `handle_reading` decrypts into a 64 KiB buffer and dispatches it when full; if that dispatch writes, the nested `handle_traffic` ran `handle_reading` again and delivered the rest of the input BIO to the owner while the owner was still inside `on_data` for the first chunk. The WebSocket client parses a chunk with a `RecvCursor` on the stack and only writes the parser state back afterwards (`handle_data_loop`), so the nested chunk was parsed from the state as it was before the first chunk (payload bytes read as a frame header, `1002`), and when the outer call resumed it overwrote whatever the nested call had stored. ### Fix `handle_traffic` now records whether it is already on the stack (`Traffic::{Idle, Running, RerunRequested}`): * A nested call only flushes the ciphertext its caller just queued (`handle_writing`) and marks a rerun; it never decrypts. * The outermost call runs passes until one completes without being re-entered. A pass that was re-entered stops before reading, so the next pass starts from `update_handshake_state` again (bytes a synchronous peer fed in during the write callback may still be handshake bytes, and only the `SSL_do_handshake` there reports completion). This is the same shape as node's `TLSWrap::Cycle()` recursion guard. Keeping the nested flush synchronous is deliberate: owners write and tear the wrapper down from the same callback (`ws.close()` inside `onmessage` writes the close frame and then fast-shutdowns the tunnel, `WebSocket::send_close_with_body` -> `clear_data`). I tried a pure "defer everything" variant: frames are delivered correctly but the server never receives the close frame written from a message handler, which the new test's server-side close code (`1000`) would catch. Flushing from a nested frame is order preserving because `handle_writing` hands out everything it has read before it invokes a callback. Wire output is unchanged for every existing flow (writes still hit the socket at the same points); what changes is that `on_data` / `on_handshake` / `on_session` are no longer delivered while the owner is inside another callback of the same wrapper. Nesting also no longer stacks 64 KiB buffers per level. Out of scope, seen while writing the tests (both pre-existing, being tracked separately): the wrapper flushes parked session/keylog events only after the data dispatch (the C path flushes before), and `ws.terminate()` on a wss-over-proxy connection does not close the proxy TCP connection. ### Verification * `test/js/web/websocket/websocket-proxy.test.ts`: burst through a CONNECT proxy, one variant per write trigger (automatic pong, `send()` from `onmessage`). The server streams a warm-up message so the client's receive window grows, then the proxy holds the burst and releases it in one write. Asserts every frame arrives intact, the reply reaches the server on its own, and the server observes the clean close. Fails on the unfixed engine with `closeCode: 1002` in 10/10 runs (release and ASAN debug builds); `createConnectProxy` gained an `onTargetData` hook for the hold. * `test/js/node/tls/node-tls-connect.test.ts`: TLSSocket over a duplex whose `'data'` handler writes back during a 128 KiB burst; asserts no nested `'data'` event, intact payload, and that the ack written from inside the handler was flushed. Fails unfixed with `nestedDataEvents: 1`. * Also in `node-tls-connect.test.ts`: a client and a server TLSSocket over a synchronous in-memory duplex pair, where every reply (including the handshake flight) is fed back into the engine from inside its own write callback.

Adds `cgroup?: string | number` to `Bun.spawn` / `Bun.spawnSync`: pass an existing cgroup directory (path or dir fd) and the child is placed in it **before it starts executing**, so limits set on that cgroup (`memory.max`, `pids.max`, …) apply from the first instruction and to everything the child forks. The motivating case is running untrusted/heavy tools next to a long-lived parent: with a memory cap on the tools' cgroup the kernel OOM-kills the tool, instead of reclaiming the parent's file-backed pages until it stalls. Bun deliberately does not create, configure or remove cgroups — that's `mkdirSync` + `writeFileSync` and depends on the host's hierarchy. It only does the one step userland can't do racelessly: joining before exec. - **cgroup v2:** `clone3(CLONE_VM|CLONE_VFORK|CLONE_INTO_CGROUP)` through a small vfork-style asm shim (x64/arm64). No migration, so the parent isn't parked across the `cgroup_threadgroup_rwsem` write that a `cgroup.procs` write costs on ≥6.0 kernels (measured ~100 ms per sporadic spawn vs ~1 ms this way). - **cgroup v1 / no clone3 (old kernel, seccomp):** the vfork child writes `"0"` to `    /cgroup.procs` before exec. Same semantics; pays the rwsem cost unless the hierarchy is mounted `favordynmods`. - Directory is opened in the parent → bad path fails with errno + path. Join failures surface as `clone3 ''`, not `posix_spawn argv[0]`. Frozen cgroups are refused (`EBUSY`) since they'd park the vfork child and the calling thread with it. - Ignored on non-Linux (like `windowsHide` on POSIX). `node:child_process` forwards the option, undocumented. ### How did you verify your code works? `test/js/bun/spawn/spawn-cgroup.test.ts`: root+cgroupfs tests (membership, fd form, descendants, over-limit child is OOM-killed while parent is untouched) plus rootless tests that exercise the plumbing against a plain directory (pre-exec write observed by the exec'd `cat`, ENOENT/EBUSY attribution, validation, child_process pass-through).

const server = http2.createServer(); server.on("session", s => console.log("server:", s.goawayCode, s.goawayLastStreamID)); server.on("stream", stream => stream.session.goaway(http2.constants.NGHTTP2_ENHANCE_YOUR_CALM, 1)); server.listen(0, "127.0.0.1", () => { const client = http2.connect(`http://127.0.0.1:${server.address().port}`); client.on("error", () => {}); client.on("connect", () => { console.log("client:", client.goawayCode, client.goawayLastStreamID); client.request({ ":path": "/" }).on("error", () => {}); }); client.on("goaway", (code, lastStreamID) => console.log("event:", code, lastStreamID, "getters:", client.goawayCode, client.goawayLastStreamID), ); client.on("close", () => { console.log("after close:", client.goawayCode, client.goawayLastStreamID); server.close(); }); }); ``` node v26.3.0 (and this branch): ``` server: 0 0 client: 0 0 event: 11 1 getters: 11 1 after close: 11 1 ``` bun 1.4.0 and main: ``` server: undefined undefined client: undefined undefined event: 11 1 getters: undefined undefined after close: undefined undefined ``` ### Cause Node's `Http2Session` (lib/internal/http2/core.js) has two getters describing the GOAWAY frame the session received: ```js get goawayCode() { return this[kState].goawayCode || NGHTTP2_NO_ERROR; } get goawayLastStreamID() { return this[kState].goawayLastStreamID || 0; } ``` `onGoawayData` fills both in before emitting `'goaway'`, and they keep their values after the session is destroyed. Neither `ClientHttp2Session` nor `ServerHttp2Session` in `src/js/node/http2.ts` defined them. The received code was already tracked (`kGoawayCode`, used to pick the rst code of streams torn down by the GOAWAY); the received Last-Stream-ID was passed to the event and then dropped. ### Fix Store the received Last-Stream-ID next to the code in both `onGoAway` handlers (before `'goaway'` is emitted, as in node) and define the two getters once on the shared `Http2Session` base class, where node defines them. They describe received GOAWAYs only: a `goaway()` this side sends does not touch them, same as node. This is a plain node compat gap. Code written for node that reads these (for example `session.goawayCode !== NGHTTP2_NO_ERROR` to tell a graceful shutdown from an errored one) gets `undefined` on bun today, so such a check treats every session as errored. No type or docs changes: node does not document these getters and `@types/node` does not declare them, they are just part of the `Http2Session` surface. ### Verification Four tests added to `test/js/node/http2/node-http2.test.js` (`describe "http2 session goawayCode / goawayLastStreamID"`). All four fail on bun 1.4.0 and pass with this change; the same scenarios run as a standalone script under node v26.3.0 and under the fixed debug build print identical output. - both properties are getters (no setter) and report `0` / `0` on a fresh client and server session - server sends `goaway(ENHANCE_YOUR_CALM, 1)`: the client reports `11` / `1` inside the `'goaway'` event and still after it was destroyed; the server's own getters stay `0` / `0` - client sends `goaway(CANCEL, 2)`: the server session reports `8` / `2`, with the same persistence check - server sends a bare `goaway()`: the client reports `0` / `1` (the implicit last processed stream id) With the debug build, `node-http2.test.js` (351 pass, 6 skip), `h2-conformance.test.ts` and the vendored node http2 goaway/shutdown tests pass. --- src/js/node/http2.ts | 11 +++ test/js/node/http2/node-http2.test.js | 130 ++++++++++++++++++++++++++ 2 files changed, 141 insertions(+) diff --git a/src/js/node/http2.ts b/src/js/node/http2.ts index 86e278a77c7f..c85e2e54cff5 100644 --- a/src/js/node/http2.ts +++ b/src/js/node/http2.ts @@ -409,6 +409,8 @@ const kReceivedGoaway = Symbol("receivedGoaway"); // The error code carried by a received GOAWAY; like Node's state.goawayCode it // takes precedence over the destroy code when streams are torn down. const kGoawayCode = Symbol("goawayCode"); +// The Last-Stream-ID carried by a received GOAWAY (Node's state.goawayLastStreamID). +const kGoawayLastStreamID = Symbol("goawayLastStreamID"); const kReleaseUnannouncedStream = Symbol("releaseUnannouncedStream"); const kGoawaySent = Symbol("goawaySent"); @@ -2082,6 +2084,13 @@ class Http2Session extends EventEmitter { // run inside it so 'close' doesn't inherit the last stream's frame.

They were declared as safe functions: ```rust #[unsafe(no_mangle)] pub extern "C" fn Blob__ref(self_: &mut Blob) #[unsafe(no_mangle)] pub extern "C" fn Blob__deref(self_: &mut Blob) ``` and `bun_runtime::webcore` re-exported them. `Blob` is an ordinary struct that also lives by value (`AnyBlob` payloads, stack locals, `Blob::dupe()` results), so a `&mut Blob` is easy to come by in safe code, and both functions have preconditions that nothing in the signature proves: - `Blob__deref` releases a count the caller must own. On a heap `Blob` it double frees against the `ExternalShared` or JS wrapper that actually owns the count (`deref` runs `deinit()`, which `heap::take`s the allocation). On a by-value `Blob` it underflows the count (`debug_assert!(is_heap_allocated())` in debug builds). - `Blob__ref` requires a heap `Blob`. `is_heap_allocated()` is encoded as `ref_count != 0`, so bumping a by-value `Blob` from 0 to 1 makes its ordinary `deinit()` run `heap::take` on an address that was never boxed. This is why the retain side needs the contract too, unlike e.g. `Bun__VmHandle__retain(&VirtualMachine)`, where the reference already proves everything the function needs. No in-tree Rust caller misuses them today; this is a contract fix. Same class as the other "safe fn that releases something it cannot prove the caller owns" fixes (#31981, #30812). ### Fix - Both are now private `unsafe extern "C" fn`s over `*mut Blob` with the ownership and threading contract in a `# Safety` section. This is the shape of `ExternalSharedDescriptor::ext_ref/ext_deref` (so the impl forwards the pointer as is) and of the other teardown exports in the crate (`AbortSignal__Timeout__deinit`, `Bun__VmHandle__release`). Taking a raw pointer rather than materializing `&mut Blob` at the FFI boundary also follows the provenance guidance in `src/CLAUDE.md` for entry points that may free their argument; the bodies are unchanged otherwise. `#[unsafe(no_mangle)]` keeps the symbols exported, so `blob.h` and the C++ callers are unaffected; per the workspace `pub` convention the items no longer need to be `pub` since no other crate imports them. - The two Rust callers (`ExternalSharedDescriptor` impl, `Blob::finalize`) now acknowledge the contract with `unsafe` blocks. `finalize` hands its `Box` over with `heap::into_raw`, which is what `Blob__deref` -> `deinit` -> `heap::take` pairs with. - The dead re-export of both names from `src/runtime/webcore/Blob.rs` is removed. - `blob.h` declared both as returning `void*`; the definitions return nothing. C++ ignores the value, so this was harmless, but the declarations now match. Intentionally not touched here, same area, different fixes: `Blob::deinit(&mut self)` still frees the allocation itself when `ref_count != 0` (it is the teardown `Blob__deref` and the structured-clone error path rely on, so changing it means auditing its callers), and the `safe fn X__deref(..)` declarations of C++-implemented refcount functions in `unsafe extern "C"` blocks are a separate population. ### Test `test/internal/source-lints/unsafe-refcount-exports.test.ts` scans the tracked Rust sources for `#[unsafe(no_mangle)]` exports named `*__ref`, `*__deref`, `*__unref` or `*__release` and requires them to be declared `unsafe`. It also asserts the pattern still finds the tree's refcount exports (currently `Blob__ref`, `Blob__deref`, `Bun__VmHandle__release`), so it cannot pass vacuously after a rename. On `main` it fails with: ``` + "src/jsc/webcore_types.rs:483: Blob__ref", + "src/jsc/webcore_types.rs:492: Blob__deref", ``` The compiler enforces the rest: reverting either signature to safe trips `unused_unsafe` (warnings are denied workspace-wide) at the two Rust call sites. ### Verification - `bun bd` builds clean; `bun bd test test/internal/source-lints/unsafe-refcount-exports.test.ts` passes, and fails with the output above with `src/` stashed. - `bun test test/internal/source-lints/` (all 17 lints) passes; `cargo fmt -p bun_jsc -p bun_runtime -- --check` clean. - Suites that drive the C++ side of the protocol (`RefPtr` in FormData, File and WebSocket) on the debug build: `test/js/web/html/FormData.test.ts`, `FormData-file-error-leak.test.ts`, `test/js/web/fetch/blob.test.ts`, `test/js/web/websocket/websocket-blob.test.ts` pass. `test/js/web/fetch/blob-file-name-ownership.test.ts` (4000 structuredClone round-trips, each finalized through `Blob__deref`) takes about 4s under the debug build on this machine and so sits at its default 5s timeout; it passes with a longer timeout, and its subprocess prints the expected output with no ASAN report. --- src/jsc/bindings/blob.h | 4 +- src/jsc/webcore_types.rs | 72 ++++++++++----- src/runtime/webcore/Blob.rs | 4 +- .../unsafe-refcount-exports.test.ts | 92 +++++++++++++++++++ 4 files changed, 144 insertions(+), 28 deletions(-) create mode 100644 test/internal/source-lints/unsafe-refcount-exports.test.ts diff --git a/src/jsc/bindings/blob.h b/src/jsc/bindings/blob.h index 9612ac6942d0..631861a37ae6 100644 --- a/src/jsc/bindings/blob.h +++ b/src/jsc/bindings/blob.h @@ -11,8 +11,8 @@ extern "C" void* Blob__dupe(void* impl); extern "C" void* Blob__getDataPtr(JSC::EncodedJSValue blob); extern "C" size_t Blob__getSize(JSC::EncodedJSValue blob); extern "C" void* Blob__fromBytes(JSC::JSGlobalObject* globalThis, const void* ptr, size_t len); -extern "C" void* Blob__ref(void* impl); -extern "C" void* Blob__deref(void* impl); +extern "C" void Blob__ref(void* impl); +extern "C" void Blob__deref(void* impl); // Opaque type corresponding to `bun.webcore.Blob`. class BlobImpl; diff --git a/src/jsc/webcore_types.rs b/src/jsc/webcore_types.rs index cd202fc83753..b3a6a52daae4 100644 --- a/src/jsc/webcore_types.rs +++ b/src/jsc/webcore_types.rs @@ -232,10 +232,11 @@ impl Blob { self.is_heap_allocated(), "`finalize` may only be called on a heap-allocated Blob" ); - // `release` returns the raw `m_ctx` pointer without dropping; - // `Blob__deref` runs `deinit()` (which `drop(heap::take)`s) when the - // count reaches zero. - Blob__deref(bun_core::heap::release(self)); + // SAFETY: `self` is the allocation `Blob::new` produced and the JS + // wrapper's `+1` is the count released here. `into_raw` hands the box + // over without dropping it; `Blob__deref` runs `deinit()` (which + // `drop(heap::take)`s) when the count reaches zero. + unsafe { Blob__deref(bun_core::heap::into_raw(self)) } } #[inline] @@ -471,34 +472,59 @@ impl Blob { unsafe impl bun_ptr::ExternalSharedDescriptor for Blob { unsafe fn ext_ref(this: *mut Self) { // SAFETY: caller guarantees `this` points to a live heap-allocated Blob. - unsafe { Blob__ref(&mut *this) } + unsafe { Blob__ref(this) } } unsafe fn ext_deref(this: *mut Self) { - // SAFETY: caller guarantees `this` points to a live heap-allocated Blob. - unsafe { Blob__deref(&mut *this) } + // SAFETY: caller guarantees `this` points to a live heap-allocated Blob + // and is releasing a count it owns. + unsafe { Blob__deref(this) } } } +/// Retain half of the refcount protocol behind `BlobImplRefDerefTraits` +/// (`src/jsc/bindings/blob.h`) and [`bun_ptr::ExternalShared`]. +/// +/// # Safety +/// `this` must point to a live `Blob` produced by [`Blob::new`], and the call +/// must happen on the thread that owns it (the count is not atomic).

The field is now the RAII owner that `bun_libarchive` already provides and that `runtime/api/Archive.rs` already uses: ```rust // before archive: Option<*mut lib::Archive>, // after archive: Option, // NonNull, archive_read_free on Drop ``` `open_archive` becomes `let archive = lib::ReadArchive::new();`, configures it with the safe `read_support_format_tar` / `read_set_options` methods through `Deref`, passes `archive.as_mut_ptr()` to the three raw setup calls (`archive_read_append_filter`, `archive_read_set_format`, `archive_read_open`), and moves it into the field at the two success exits; its three `return Err(..)` paths simply drop it. `step()` holds `let archive: &lib::Archive = (*this).archive.as_deref().unwrap();` and reuses it at the two `error_string()` sites. The `archive` arm of the `Drop` impl is deleted (the `out_fd` / `dest` closes stay). One file, 17 insertions and 38 deletions; removes 5 unsafe blocks (the scopeguard closure, two setup calls, one `error_string` call, and the `Drop` arm) and the two remaining raw dereferences of the field inside `step()`. ## Why Ownership of the `struct archive *` is now stated by the type: the stream owns exactly one handle once `open_archive` succeeds, every early return in `open_archive` releases it without a guard to disarm, and the handle can no longer be leaked or double-freed by a future edit to `Drop`. It is zero-cost: `Option` uses the `NonNull` niche, so the field shrinks from 16 to 8 bytes; the `Deref` and `as_mut_ptr()` calls are inlined pointer reinterpretations; and teardown performs one FFI call instead of two, because libarchive's `archive_read_free` itself closes the filters (`_archive_read_free` calls `archive_read_close` for an open archive, and `__archive_read_free_filters` runs `close_filters` in every state), with the stream's own read callback never invoked during either. The only added instruction is the drop-glue discriminant test of the always-`None` previous value when the field is assigned, once per archive open. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

Node's `buildNgHeaderString` emits one field per element for every block, `pushStream()` included. The same missing branch meant `pushStream()` had no single-value enforcement at all: `{"content-type": ["a", "b"]}` was sent as `content-type: a,b`, `{":path": ["/a", "/b"]}` as `:path: /a,/b`, and `{"content-type": "a", "Content-Type": "b"}` as two fields. Node throws `ERR_HTTP2_HEADER_SINGLE_VALUE` synchronously from `pushStream()` for all three (verified against v26.3.0). ## Fix - `src/runtime/api/bun/h2_frame_parser.rs`: `push_promise()` gets the same value handling as `request()` and `send_trailers()`: an array encodes one field per element (each element validated like a single value, so an element with CR/LF/NUL or a null element is rejected with `ERR_HTTP2_INVALID_HEADER_VALUE` exactly as it is for `respond()`), and single-value fields are tracked with the same `strictSingleValueFields`-gated bitset the other encoders use. The never-index lookup is done once per header name and applied to every element. - `src/js/node/http2.ts`: `pushStream()` runs `assertSingleValueHeaders()` (the check `respond()` / `additionalHeaders()` / `request()` already run) before a promised stream id is reserved, so the violation throws synchronously from `pushStream()` like node, reserves no stream, and never reaches the encoder. Behavior checked against node v26.3.0 with a per-case probe: | `pushStream()` headers | node | main | this PR | | --- | --- | --- | --- | | `"x-multi": ["a", "b"]` | two fields | one field `a,b` | two fields | | `"set-cookie": ["c1=1", "c2=2"]` | two fields | one field `c1=1,c2=2` | two fields | | `"x-none": []` | nothing sent | `x-none: ` (empty value) | nothing sent | | `"x-num": [1, 2]` | `1`, `2` | `1,2` | `1`, `2` | | `"content-type": ["a", "b"]` | throws `ERR_HTTP2_HEADER_SINGLE_VALUE` | sent as `a,b` | throws | | `":path": ["/a", "/b"]` | throws | sent as `/a,/b` | throws | | `"content-type": "a", "Content-Type": "b"` | throws | both sent | throws | | same with `strictSingleValueFields: false` | two fields | one field | two fields | | `"x": ["ok", null]` | sends `null` (stringified) | one field `ok,` | callback `ERR_HTTP2_INVALID_HEADER_VALUE` | The last row is the one deliberate difference from node: rejecting a null element is what bun's `request()` / `respond()` already do for array elements, so `pushStream()` now matches the rest of bun rather than node's `String(null)`. Not changed here: a block that fails validation after some of its fields were already fed to the HPACK encoder still desyncs the encoder table from the peer. That is pre-existing (the same `{"x-a": "fine", "x-bad": "a\nb"}` push kills the session with COMPRESSION_ERROR before and after this change, and it applies to every encoder) and is what #33470 fixes by collecting the block before encoding; this change keeps `push_promise()`'s loop shape so that PR rebases mechanically either way. #37568 (coerce values in JS before taking the id) passes arrays through to the native encoder and is complementary. ## Verification Five tests added to `test/js/node/http2/node-http2.test.js`, asserting on the flat header list the client decodes from the wire (one name/value pair per field): - array value sends one field per element; empty array sends nothing; `[x]` sends one field (also for a pseudo-header) - every element of a `[http2.sensitiveHeaders]` header arrives never-indexed - the three single-value violations throw `ERR_HTTP2_HEADER_SINGLE_VALUE` synchronously, the callback is never invoked, and the next push still gets stream id 2 - `strictSingleValueFields: false` sends each element of a single-value header - an element containing LF, or a null element, is reported through the callback as `ERR_HTTP2_INVALID_HEADER_VALUE` and nothing is pushed All five fail on the current release (`USE_SYSTEM_BUN=1`) and pass with this change. The rest of `node-http2.test.js` (352 tests), `h2-conformance.test.ts`, `h2-push-refusal-staged.test.ts`, and the ported node push tests (`test-http2-server-push-stream*.js`, `test-http2-compat-serverresponse-createpushresponse.js`, `test-http2-respond-file-push.js`, `test-http2-server-push-disabled.js`, `test-http2-single-headers-validation-disabled.js`) pass with the debug build. --- src/js/node/http2.ts | 2 + src/runtime/api/bun/h2_frame_parser.rs | 113 ++++++++++--- test/js/node/http2/node-http2.test.js | 209 +++++++++++++++++++++++++ 3 files changed, 298 insertions(+), 26 deletions(-) diff --git a/src/js/node/http2.ts b/src/js/node/http2.ts index c85e2e54cff5..ff7409618401 100644 --- a/src/js/node/http2.ts +++ b/src/js/node/http2.ts @@ -3434,6 +3434,8 @@ class ServerHttp2Stream extends Http2Stream { } headers = { ...headers }; assertNoConnectionHeaders(headers); + // Thrown synchronously like node, before a promised stream id is reserved. + if (session[kStrictSingleValueFields] !== false) assertSingleValueHeaders(headers); const sensitives = headers[sensitiveHeaders]; // Note: the sensitiveHeaders symbol stays on the object — the native header walk skips // symbol keys, and deleting it here would flip the object into dictionary mode, diff --git a/src/runtime/api/bun/h2_frame_parser.rs b/src/runtime/api/bun/h2_frame_parser.rs index afc5337db482..dd307ab555fe 100644 --- a/src/runtime/api/bun/h2_frame_parser.rs +++ b/src/runtime/api/bun/h2_frame_parser.rs @@ -8381,6 +8381,7 @@ impl H2FrameParser { let mut name_buffer = [0u8; 4096]; let mut encoded_headers: Vec = Vec::new(); + let mut single_value_headers = [false; SINGLE_VALUE_HEADERS_LEN]; // A PUSH_PROMISE carries a REQUEST, so request pseudo-headers are valid even on the server. // Pseudo-headers must be encoded first, so iterate twice. @@ -8438,7 +8439,6 @@ impl H2FrameParser { if js_value.is_empty_or_undefined_or_null() { continue; } - let value_str = js_value.to_js_string(global_object)?; // All-digit names can't be passed to get_truthy (integer-index-like names trip // a debug assert in getIfPropertyExistsImpl) and can never be sensitive. let never_index = if Self::is_index_like_name(validated_name) { @@ -8449,32 +8449,93 @@ impl H2FrameParser { None => sensitive_arg.get_truthy(global_object, name)?.is_some(), } }; - let value_slice = value_str.to_slice(global_object); - let value = value_slice.slice(); - if !is_valid_header_value(value) { - return Err(global_object - .err( - JscErrorCode::HTTP2_INVALID_HEADER_VALUE, - format_args!( - "Invalid value for header \"{}\"", - BStr::new(validated_name) - ), + let mut encode_value = |item: JSValue| -> JsResult> { + let value_str = item.to_js_string(global_object)?; + let value_slice = value_str.to_slice(global_object); + let value = value_slice.slice(); + if !is_valid_header_value(value) { + return Err(global_object + .err( + JscErrorCode::HTTP2_INVALID_HEADER_VALUE, + format_args!( + "Invalid value for header \"{}\"", + BStr::new(validated_name) + ), + ) + .throw()); + } + bun_output::scoped_log!( + H2FrameParser, + "encode header {} {}", + BStr::new(validated_name), + BStr::new(value) + ); + if this + .encode_header_into_list( + &mut encoded_headers, + validated_name, + value, + never_index, ) - .throw()); - } - if this - .encode_header_into_list( - &mut encoded_headers, - validated_name, - value, - never_index, - ) - .is_err() - { - // Same as the request/respond encode failures: nghttp2 fails the whole - // session, and node never surfaces this through the pushStream callback. - this.schedule_header_compression_session_error(); - return Ok(JSValue::js_number(-1.0)); + .is_err() + { + // Same as the request/respond encode failures: nghttp2 fails the whole + // session, and node never surfaces this through the pushStream callback. + this.schedule_header_compression_session_error(); + return Ok(Some(JSValue::js_number(-1.0))); + } + Ok(None) + }; + if js_value.js_type().is_array() { + let mut value_iter = js_value.array_iterator(global_object)?; + if let Some(idx) = this.single_value_index_checked(validated_name) { + if value_iter.len > 1 || single_value_headers[idx] { + return Err(global_object + .err( + JscErrorCode::HTTP2_HEADER_SINGLE_VALUE, + format_args!( + "Header field \"{}\" must only have a single value", + BStr::new(validated_name) + ), + ) + .throw()); + } + single_value_headers[idx] = true; + } + while let Some(item) = value_iter.next()?

From d9e27511762dc99006036f589503149a9ca00081 Mon Sep 17 00:00:00 2001 From: robobun Date: Tue, 11 Aug 2026 15:04:44 -0700 Subject: [PATCH 241/304] websocket: enter tunnel forwarding mode before dispatching open (#37610) ### What For `wss://` through an HTTP CONNECT proxy (tunnel mode), the upgrade client keeps owning the proxy socket after the 101 and forwards everything it reads into the TLS tunnel. It only switched into that forwarding state (`State::Done`) after `did_connect_with_tunnel` returned. That call dispatches the `open` event, so an open handler that spins the event loop (`expect(...).resolves` in `bun:test`, a debugger pause, `Bun.build()` with an async plugin `setup`) can deliver bytes from the proxy socket to `handle_data` while the call is still on the stack. At that point the state is still `Reading` and `outgoing_websocket` has already been taken, so `handle_data` marked the client failed, dropped the proxy state (shutting the tunnel down while nothing is attached to it to hear about it) and closed the proxy connection. After `open` returned, C++ attached the new WebSocket client to the dead tunnel: ```ts // bun test, wss:// server behind a CONNECT proxy; the server answers "go" with "hello" ws.onopen = () => { ws.send("go"); expect(replyForwardedByProxy).resolves.toBeUndefined(); // spins the loop inside open }; ws.onmessage = e => console.log(e.data); // never fires ws.onclose = e => console.log(e.code); // never fires either; the server sees 1006 ``` The WebSocket stays `OPEN` forever with no `message` and no `close`, and the server sees the connection drop. ### Fix `src/http_jsc/websocket_client/WebSocketUpgradeClient.rs`: set `State::Done` before calling `did_connect_with_tunnel`, the same order the non-tunnel arm already uses (it detaches the socket before `did_connect`). Why this is enough on its own: in `Done`, `handle_data` hands the bytes to the tunnel. The 101 that got us here was decrypted by the tunnel's `SslWrapper`, whose traffic pass is still on the stack and is not re-entrant, so bytes received during the call are only queued in the read BIO and get decrypted when that pass resumes. By then `did_connect_with_tunnel` has returned and `didConnectWithTunnel` has pointed the tunnel at the connected WebSocket client, whose C++ side is already `OPEN`, so the frames come out as ordinary `message` events and the connection carries on. The C++ ordering (`didConnect()` before `setConnectedWebSocket`) does not need to change. ### Test `test/js/web/websocket/websocket-proxy.test.ts`: the open handler sends `"go"` and spins with `expect().resolves` until the in-process proxy has forwarded the reply and one more loop iteration has polled I/O (the spin only re-checks its promise after an `auto_tick`, which always polls, so the client has read the reply off the proxy socket by the time the spin ends). Without the fix it fails deterministically (30/30 release, 10/10 debug): ``` - "clientCloseCode": 1000, - "received": ["hello"], - "serverCloseCode": 1000, + "clientCloseCode": "client never closed (server saw the connection drop)", + "received": [], + "serverCloseCode": 1006, ``` With the fix it passes (15/15 on the debug/ASAN build), along with the rest of `websocket-proxy.test.ts`, the other `websocket-proxy-*` files, `test-ws-bidir-proxy.test.ts` and `test/js/first_party/ws/ws-proxy.test.ts`. ### Notes - Also looked at the `if state == State::Failed` branches in `connect()` that were flagged alongside this: they are unreachable. `connect_group` / `connect_unix_group` write the client into the socket's ext slot only after uSockets' connect returns, so no callback can reach the client while `connect()` is running, and nothing else sets `Failed` before it returns. Left untouched here since #37594 is rewriting that function. - Surfaced by review of #37594, which preserves the old order; whichever of the two lands second needs a trivial rebase of this block. --- .../WebSocketUpgradeClient.rs | 17 +++- test/js/web/websocket/websocket-proxy.test.ts | 80 +++++++++++++++++++ 2 files changed, 94 insertions(+), 3 deletions(-) diff --git a/src/http_jsc/websocket_client/WebSocketUpgradeClient.rs b/src/http_jsc/websocket_client/WebSocketUpgradeClient.rs index 3b466c6f711f..53df28c19871 100644 --- a/src/http_jsc/websocket_client/WebSocketUpgradeClient.rs +++ b/src/http_jsc/websocket_client/WebSocketUpgradeClient.rs @@ -1615,6 +1615,20 @@ impl HTTPClient { // SAFETY: short-lived `&mut` for the field take. let ws = unsafe { (*this).outgoing_websocket.take().unwrap() }; + // Switch to forwarding before entering C++. did_connect_with_tunnel + // dispatches `open`, and an open handler that spins the event loop + // (expect().resolves, a debugger pause) delivers socket data to + // handle_data while this frame is on the stack; with the state + // still `Reading` and `outgoing_websocket` taken, handle_data + // would fail the client and close the socket.

The 4 producers adopt the reply where the c-ares layer hands it over: the `impl_cares_record_type!` and `hostent_newtype!` handlers replace their `is_null()` checks with `NonNull::new(..).map(adopt)`, and the `any` and `hostent_ttls_newtype!` handlers, which receive a `Box` from the parser, release it with `heap::into_raw_nn` into the same wrapper instead of `heap::into_raw`. Both consumers lose their guards: `process_resolve` binds `let Some(mut node) = result` and `node` drops at the end of the function, `drain_pending_cares` binds `let Some(mut addr) = result`, calls `addr.to_js_response(..)` instead of `(*addr).to_js_response(..)` at its 2 sites, and `addr` drops after the waiter loop; the `None` it forwards to `process_resolve` on the no-reply path now needs no comment. `CAresRecordType::destroy` is unchanged per type and has exactly one caller, the `Drop` impl. The two ad hoc `T::destroy` sites are gone; the wrapper adds three one-line `unsafe` blocks (`deref`, `deref_mut`, `drop`) and each of the 4 producers gains a one-line `unsafe { OwnedReply::adopt(..) }` whose SAFETY comment states why that reply is ours to free. One file, +71/-55 lines. ## Why Who frees a reply, and on which path, is now answered by the parameter type: `Option>` is freed by whoever holds it, while the reverse-lookup hostent that c-ares only lends to `GetHostByAddrInfoRequest` keeps its `Option<*mut struct_hostent>`, so the owned and lent cases differ in type instead of by convention. A consumer can no longer forget to free a reply on one of its exit paths, and the free itself is written in one place instead of two. It is zero-cost: `Option>` is one nullable pointer (the `NonNull` niche) where `Option<*mut T>` was two words, the producers' `NonNull::new` is the same null check they already performed, `Box::into_raw` and `heap::into_raw_nn` compile to the same thing, and the drop glue is the same `T::destroy` call the guards made at the same scope exits (the workspace builds with `panic = "abort"`, so no unwind paths or drop flags are introduced). Part of a series of small type-system hardening changes; each PR stands alone. ## Related #36123 also removes these two `scopeguard` sites, by wrapping the `Option<*mut T>` in a `CAresReply` at the two consumer sites and leaving the signatures unchanged. This PR instead moves the ownership into the signatures and adopts the reply at the producers, so the two conflict textually in `process_resolve` and `drain_pending_cares`; whichever lands second needs a rebase of that hunk. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates. Debug build succeeds. test/js/node/dns/dns-resolver-concurrent-timeout.test.ts, dns-tcp-bidirectional-poll.test.ts, node-dns.test.js: 97 pass, 29 fail; the same 29 node-dns.test.js tests (resolveSrv/Txt/Soa/Naptr/Caa/Mx/Ns/Ptr/Cname against bun.sh/socketify.dev, lookup example.com, reverse/lookupService on 1.1.1.1/8.8.8.8) fail identically on main with ESERVFAIL/ETIMEOUT/ENOTFOUND because they need public internet DNS, so they are pre-existing and unrelated to this change. --- src/runtime/dns_jsc/dns.rs | 126 +++++++++++++++++++++---------------- 1 file changed, 71 insertions(+), 55 deletions(-) diff --git a/src/runtime/dns_jsc/dns.rs b/src/runtime/dns_jsc/dns.rs index 950620131d25..d6a9b5e20c41 100644 --- a/src/runtime/dns_jsc/dns.rs +++ b/src/runtime/dns_jsc/dns.rs @@ -389,11 +389,45 @@ pub trait CAresRecordType: Sized { global: &JSGlobalObject, type_name: &'static str, ) -> JsResult; - /// Free a c-ares-allocated reply struct (`ares_free_data` / `ares_free_hostent`). - /// SAFETY: `this` must be the pointer c-ares handed to the callback; not aliased. + /// Free a reply; called once per reply, by `OwnedReply`'s `Drop`. + /// SAFETY: `this` must be the pointer an `OwnedReply` adopted; not aliased. unsafe fn destroy(this: *mut Self); } +/// The parsed reply of one query, freed by `T::destroy` when dropped. +#[repr(transparent)] +pub(crate) struct OwnedReply(NonNull); + +impl OwnedReply { + /// SAFETY: `reply` must be a live reply that `T::destroy` frees, and the + /// caller must give up every other use of it. + unsafe fn adopt(reply: NonNull) -> Self { + Self(reply) + } +} + +impl core::ops::Deref for OwnedReply { + type Target = T; + fn deref(&self) -> &T { + // SAFETY: `adopt` took the only handle to a live reply; only `drop` frees it. + unsafe { self.0.as_ref() } + } +} + +impl core::ops::DerefMut for OwnedReply { + fn deref_mut(&mut self) -> &mut T { + // SAFETY: as in `deref`; `&mut self` rules out any other live borrow. + unsafe { self.0.as_mut() } + } +} + +impl Drop for OwnedReply { + fn drop(&mut self) { + // SAFETY: `adopt`'s contract; no borrow handed out by `deref` outlives `self`. + unsafe { T::destroy(self.0.as_ptr()) } + } +} + pub(crate) struct ResolveInfoRequest { // TODO: should be Option<&'a Resolver> (struct gets <'a>); raw ptr until reconciled with intrusive RC pub resolver_for_caching: Option<*mut Resolver>, @@ -482,7 +516,7 @@ impl ResolveInfoRequest { this: *mut Self, err_: Option, timeout: i32, - result: Option<*mut T>, + result: Option>, ) { // SAFETY: this is the heap-allocated request c-ares calls back with unsafe { @@ -1634,20 +1668,11 @@ impl CAresLookup { this: *mut Self, err_: Option, _timeout: i32, - result: Option<*mut T>, + result: Option>, ) { // syscall = "query" + ucfirst(TYPE_NAME); each `CAresRecordType` impl // carries the precomputed literal. let syscall = T::SYSCALL; // e.g. "querySrv" - // This path is reached when the pending cache is full (`.disabled`), - // so we own the c-ares result here.

The primitive without `createWriteStream`: ```js const fd = fs.openSync(p, "w"); fs.writeSync(fd, "AAAAAAAAAA"); fs.writeSync(fd, Buffer.from("XX"), 0, 2, NaN); // node: "AAAAAAAAAAXX" bun (before): "XXAAAAAAAA" ``` ## Cause `writeAll` in `src/js/internal/fs/streams.ts` retries a short write with `pos += bytesWritten`. `pos` starts as `undefined` (no `start` option) so the retry passes `NaN`. Node's `writeAll` does the same; it works there because Node's native `GetOffset` ([src/node_file.cc](https://github.com/nodejs/node/blob/main/src/node_file.cc)) returns `-1` (current file offset) for any value that isn't a safe JS integer. Bun's `fs.write` argument parser instead ran `i52::from_js(NaN)`, which is `(to_int64(NaN) << 12) >> 12 = 0`, and set `args.position = Some(0)`. strace confirms: `write(4 MiB) = 1048576`, then `pwrite64(3 MiB, 0)`, `pwrite64(2 MiB, 0)`, `pwrite64(1 MiB, 0)`; the remaining size reaches zero so the loop reports success. `-Infinity`, fractional values, and numbers past `MAX_SAFE_INTEGER` mis-coerced the same way, and the `fs.readv`/`fs.writev` `position` parser had the same defect (plus it threw on non-number values Node accepts). ## Fix `i52::offset_from_js` now implements Node's `GetOffset`: a `position` selects `pwrite`/`pwritev`/`preadv` only when `Number.isSafeInteger(position)`. Every other shape (NaN, ±Infinity, fractional, out-of-range, non-number) leaves `position = None` so dispatch picks the non-positional syscall at the current offset. The `fs.write` buffer and string overloads and the shared `readv`/`writev` parser all go through it. This includes BigInt, which Bun previously honored as a positional write on the buffer overload; the `writeSync works with bigint` test now asserts the Node behavior (current offset). `writeAll` also now keeps `pos` undefined across retries, so a custom `options.fs.write` observes the same argument Node passes. ## Verification New `describe.each` in `test/js/node/fs/fs.test.ts` runs `writeSync` (buffer and string), async `fs.write`, `writevSync`, `readvSync`, `FileHandle.write`, and `FileHandle.writev` against each of `NaN`, `±Infinity`, `1.5`, `MAX_SAFE_INTEGER + 1`, and `5n` and asserts the I/O happens at the current offset; a second block covers non-number `writevSync` positions. Two `createWriteStream` tests cover the headline bug: one simulates a short write via `options.fs.write` and asserts the retry position stays `undefined` and the file reads `AAAABBBBCCCCDDDD`; one (Linux) runs the `ulimit -f` repro and asserts `{ev: ["error:EFBIG"], bytesWritten: 1048576, head: "AAAAAAAA"}`. 40 of the 49 new cases fail on the unfixed build (the others are guard cases or +Infinity which already happened to truncate to `-1`). All pass with this change, along with the existing `writeSync`/`writev`/`readv` suites and Node's `test-fs-writev*`/`test-fs-readv*` parallel tests. Supersedes #32292 (the `readv`/`writev` half of this same class). --- **no test proof** · iteration 3 · Platform-specific test(s) that do not run on this machine.

Rewrites 89 statement-position `.ok();` calls to `let _ = ...;`. Every one of them is a `write!`/`write_all`/`splat_byte_all` into a `Vec` or a best-effort console writer, so nothing was being dropped that mattered, but `.ok();` reads like the error is being handled when it is being thrown away. `let _ =` is already the majority spelling in the tree (153 uses) and says what is happening. No behavior change. ### How did you verify your code works? `cargo check -p bun_jsc -p bun_runtime -p bun_install -p bun_md` and `cargo fmt --all` are clean.

The seven fields were `pub(crate)`, so anything in `bun_sql_jsc` could have written a `month = 13` and reached that index. Nothing does today (there is no reader or writer of these fields outside `MySQLValue.rs`), so this just drops the visibility to keep it that way. ### How did you verify your code works? `cargo check -p bun_sql_jsc` is clean with the fields private, which is the proof that nothing outside the module touched them. --- src/sql_jsc/mysql/MySQLValue.rs | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/src/sql_jsc/mysql/MySQLValue.rs b/src/sql_jsc/mysql/MySQLValue.rs index d6aca8521ff0..5598117e8e5d 100644 --- a/src/sql_jsc/mysql/MySQLValue.rs +++ b/src/sql_jsc/mysql/MySQLValue.rs @@ -420,13 +420,13 @@ impl Value { #[derive(Default, Clone, Copy)] pub struct DateTime { - pub(crate) year: u16, - pub(crate) month: u8, - pub(crate) day: u8, - pub(crate) hour: u8, - pub(crate) minute: u8, - pub(crate) second: u8, - pub(crate) microsecond: u32, + year: u16, + month: u8, + day: u8, + hour: u8, + minute: u8, + second: u8, + microsecond: u32, } impl DateTime { From 64c972faf7717cafd288c5e5fd93e867ceb90e52 Mon Sep 17 00:00:00 2001 From: robobun Date: Tue, 11 Aug 2026 15:18:12 -0700 Subject: [PATCH 246/304] strings: carry RawSlice in ZigStringSlice borrowed variants (#37560) ## What `ZigStringSlice` in `src/bun_core/string/mod.rs` spelled the borrowed byte view three times, once per borrowed variant, as a separate `*const u8` plus `usize`, and the empty value was the in-band sentinel `Static(ptr::null(), 0)` (spelled out in both `EMPTY` and `empty()`). Because a null data pointer was a legal payload, `slice()` needed two `len == 0` guard arms in front of two `from_raw_parts` unsafe blocks, and `length()`, `clone_ref()` and the `WtfBorrowed` construction in `String::to_thread_safe_slice` each re-spelled the pair. The borrowed variants now carry `bun_core::RawSlice`, the type this crate already uses for holder-lifetime `*const [T]` fields: ```rust // before Static(*const u8, usize), WTF { string_impl: *const WTFStringImplStruct, ptr: *const u8, len: usize }, WtfBorrowed { string_impl: *const WTFStringImplStruct, ptr: *const u8, len: usize }, pub const EMPTY: Self = Self::Static(core::ptr::null(), 0); // after Static(RawSlice), WTF { string_impl: *const WTFStringImplStruct, bytes: RawSlice }, WtfBorrowed { string_impl: *const WTFStringImplStruct, bytes: RawSlice }, pub const EMPTY: Self = Self::Static(RawSlice::EMPTY); ``` `from_utf8_never_free` wraps with `RawSlice::new`, `empty()` returns `EMPTY`, the two `WTFStringImplExt` constructors in `wtf.rs` pass `RawSlice::new(self.latin1_slice())`, and `to_thread_safe_slice` moves the `bytes` payload from the `Static` it matched into the `WtfBorrowed` it builds. The 3 readers (`slice()`, `length()`, `clone_ref()`) bind the single payload in one or-pattern arm each; `slice()` is now `bytes.slice()` with no guard arms and no unsafe. The two `ZigString` sites (`to_slice`, `to_slice_fast`) that built `Static` directly from the untagged pointer and `len` share a new private `to_slice_borrowed` helper holding the one `from_raw_parts` call, so the change removes 2 unsafe blocks and adds 1. `from_utf8_never_free` gains `#[inline]` because it is now on the `#[inline] to_slice` path. The only uses of these variants outside `bun_core` are two `matches!(.., Static(..))` / `matches!(.., WTF { .. })` checks in `webcore/Blob.rs`, which compile unchanged. No dependency changes. ## Why A borrowed payload is now one value whose type says it is a view into storage owned by someone else (the caller for `Static`, the held ref for `WTF`, the enclosing `underlying` for `WtfBorrowed`), and a null pointer is no longer a representable payload, so the `len == 0` special cases in `slice()` go away rather than being re-checked on every read. `RawSlice` is `#[repr(transparent)]` over `*const [u8]`, the same two words it replaces, so each variant and the 32-byte enum keep their layout (`shell/interpreter.rs` sizes `ZigStringSlice` for GC accounting), `RawSlice::new` and `slice()` are pointer casts, `to_slice_borrowed` produces exactly the untagged pointer and `len` the two sites stored before, and `slice()` drops two branches without gaining any. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

Now: ```rust // after struct OwnedWalker(NonNull); // Drop frees the allocation struct ActiveWalk { // field order is drop order iter: GlobWalkerIterator, // borrows the walker, dropped first _walker: OwnedWalker, } pub(crate) struct PackageFilterIterator<'a> { patterns: &'a [Box<[u8]>], pattern_idx: usize, root_dir: &'a [u8], active: Option, } ``` `init_walker` becomes `start_walk(&self) -> Result`, which allocates with `heap::alloc_nn`, builds and inits the iterator, and returns both; on the `init` error path the two locals drop in the same iterator-then-walker order, so the manual teardown is gone. `next` matches on `self.active`: `None` starts the walk for `pattern_idx` or ends the iteration, `Ok(None)` from the iterator resets `active` and advances `pattern_idx`, and per-entry errors are printed as before. `walker_next`, `deinit_walker`, the `valid` field and `impl Drop for PackageFilterIterator` are deleted. Of the 4 `unsafe` blocks, 2 remain (materializing the lifetime-erased `&mut` for the iterator in `start_walk`, and the free in `OwnedWalker::drop`). The 2 call sites (`filter_run.rs`, `multi_run.rs`; both pass locals that outlive the iterator) compile unchanged, the lifetime being inferred. One file, +60/-103 lines. ## Why The "no walk in progress" and "walk in progress for `pattern_idx`" states are now the two variants of `Option`, so a null walker paired with an initialized iterator (or vice versa) is unrepresentable, the iterator-before-walker drop order is fixed by field declaration order instead of by two functions agreeing, and the caller-must-outlive-us contract on `patterns` / `root_dir` is a lifetime parameter instead of a comment. It is zero-cost: `Option` uses the `NonNull` niche, so the struct shrinks by the `valid` byte and is otherwise laid out as before (the walker pointer plus the inline iterator), `&[T]` has the same fat-pointer layout as `RawSlice`, `heap::alloc_nn` / `heap::destroy` compile to the `Box::into_raw` / `Box::from_raw` pair the old code used, and `next` performs the same length comparison and bounds check per pattern as before.

They now take the slices directly and are safe: ```rust // before pub(crate) unsafe fn write_u8<..>(input: *const u8, len: usize, to_ptr: *mut u8, to_len: usize) -> Result unsafe fn byte_length_u8<..>(input: *const u8, len: usize) -> usize unsafe fn construct_from_u8<..>(input: *const u8, len: usize) -> Vec unsafe fn construct_from_u16<..>(input: *const u16, len: usize) -> Vec // after pub(crate) fn write_u8<..>(input: &[u8], to: &mut [u8]) -> Result fn byte_length_u8<..>(input: &[u8]) -> usize fn construct_from_u8<..>(input: &[u8]) -> Vec fn construct_from_u16<..>(input: &[u16]) -> Vec ``` The bodies only change by reading `input.len()` / `to.len()` instead of the separate length arguments. The four `extern "C"` entry points (`Bun__encoding__writeLatin1`, `byteLengthLatin1AsUTF8`, `constructFromLatin1`, `constructFromUTF16`), which are the only places where the validity proof actually comes from C++, form the slices once with `bun_core::ffi::slice` / `slice_mut` and then call safe code, the same shape `byteLengthUTF16AsUTF8` and `toString` in the file already use. `write_u16`'s base64 arm forms `to` with one `ffi::slice_mut` after narrowing and calls the safe `write_u8`; `construct_from_u16`'s base64 arm passes `&narrowed`; the `_dyn` wrappers become plain `dispatch_encoding!` calls; `Buffer.fill` passes the `s` / `buf` slices it already had. 13 call sites in 8 functions updated, 9 `unsafe` blocks and 4 `unsafe` signatures removed, and the `# Safety` sections that described the `(ptr, len)` contracts go with them. `write_u16` intentionally keeps its raw-pointer signature: its `Ucs2` / `Utf16le` arm accepts overlapping source and destination (`ptr::copy`), which `&[u16]` plus `&mut [u8]` cannot express, so the two `write_u16` sites in `buffer.rs` are left as they are. ## Why The "`input` and `to` must be valid and must not overlap" requirement that `write_u8` carried in a doc comment is now stated by the `&[u8]` / `&mut [u8]` parameter pair, and the remaining `unsafe` in this code is concentrated at the FFI boundary where the pointers actually come from. It is zero-cost: the emptiness early-returns stay where they were, slice formation moves from callee to caller rather than being added, `dispatch_encoding!` monomorphisation is unchanged, and the sites that previously split a real slice into `(ptr, len)` only to re-form it now skip that round trip. The one instruction that is new is the null test `ffi::slice_mut` performs on the destination pointer in `writeLatin1` and in `write_u16`'s base64 arm; it is what keeps a `(null, 0)` destination (a zero-length JSC view) accepted now that `write_u8`'s `to_len == 0` early return is no longer the first thing to see the raw pointer.

The two hand-written impls were functionally identical; `ReadFile` gains `bun_io::intrusive_io_request!` so both recover the parent through `IntrusiveIoRequest` instead of an open-coded `from_field_ptr!`. `ReadFileUV` keeps its own impl (different shape). - `impl_js_sink_forwarders!` (Sink.rs, next to `impl_js_sink_abi!`): the eight 1:1 `JsSinkType` forwarders shared by `ArrayBufferSink`, `FileSink`, `FetchRequestBodySink`, `HTTPServerWritable`, and `NetworkSink`. Per-sink items (`finalize`, `construct`, `end_from_js`, `source`, `done`, `HAS_*`) stay hand-written. - `CopyFile::fallback_read_write`: the `read_write_fallback` call plus error recording appeared three times in `do_copy_file_range`. - `Blob::set_content_type_from_js` and `S3File::finish_s3_blob`: the write-path `options.type` override (in `do_write` and `get_writer`) and the S3 constructor epilogue (in both `construct_s3_file_with_s3_credentials*` fns) were each duplicated verbatim. - `S3File::parse_s3_path_or_blob`/`resolve_s3_blob` and `S3Client::construct_blob`/`blob_and_options`: shared argument parsing for the S3 static and instance methods. `MissingPathError` preserves the per-method split between `MISSING_ARGS` and invalid-argument errors (`unlink` always reports `MISSING_ARGS`; the others only when no argument was passed). - The explicit 14-arm typed-array `JSType` lists in Blob construction use the existing `JSType::is_array_buffer_like()` (same 14-type set). Net -401 lines of src. ## History Originally the top of the foundations/install-cli/jsc-runtime stack split from #31912. Main moved far enough that every file conflicted, so this was re-derived against current main and retargeted at `main`; it has no code dependency on the other PRs in that stack. ## Tests The consolidated paths had no coverage of their error contracts, so this adds characterization tests pinning them: - `test/js/bun/s3/s3-argument-validation.test.ts`: per-method static rejection messages (including `stat` reusing the "get size" wording), the instance-method `ERR_MISSING_ARGS` vs `ERR_INVALID_ARG_TYPE` split, `unlink` always reporting `MISSING_ARGS`, and the S3 `writer()` non-string `type` rejection - `test/js/web/fetch/blob-write.test.ts`: `Bun.file().write()` `options.type` contract (non-string throws, valid types lowercased, known types resolved through the mime table, invalid types ignored) - `test/js/web/fetch/blob.test.ts`: Blob construction from all 14 ArrayBuffer-like types, as a direct body value and as an array part Because this is a behavior-preserving refactor, these tests pass identically with and without the src changes by design; that is the equivalence check, not a gap. ## Verification - Line-by-line audit against main for each consolidation: error messages, argument-eating order, drop order, and the unsafe parent-pointer recovery in `schedule_close`/`on_close_io_request` are unchanged (the macro's two trampolines are `WriteFile`'s current impl statement for statement, differing only in fully-qualified paths; `ReadFile` moves from its older `&mut *from_field_ptr!` form onto that same already-landed shape) - `bun run rust:check-all`: all 10 CI target triples pass - Debug (ASAN) build: the three test files above (102 pass), sink suites plus request-body and server-response stream suites (9161 pass), `Bun.write` including both `copyFileRange`-unavailable fallback tests, local S3 suites (38 pass), blob/FormData suites (165 pass). The large-file fallback test needs more than the 5s default on this ASAN box with or without the change. --- **no test proof** · iteration 17 · Platform-specific test(s) that do not run on this machine.

console.log("entry:", rm()); await import("./page.js"); // page.js import { rm } from "./shared.js"; console.log("page:", rm()); // shared.js const { value } = require("./wrapped.js"); // require() makes wrapped.js an __esm-wrapped module export function rm() { return "local rm " + value; } // wrapped.js (a .js file: in TypeScript the parser drops the unused import) import { rm } from "fs/promises"; // unused, tree-shaken out of the chunk export const value = 42; ``` ``` TypeError: path must be a string or TypedArray code: "ERR_INVALID_ARG_TYPE" entry: Promise { } ``` The cross-chunk `rm` import is bound to `fs/promises.rm` instead of the local function. Without `--bytecode`, or with `bun run` on the emitted chunks, it prints `entry: local rm 42` / `page: local rm 42`. On a debug build the compiled binary fails at startup instead with `Imports different between parseFromSourceCode and fallbackParse`, since `BunAnalyzeTranspiledModule.cpp` cross-checks the record against JSC's analyzer. This is the report of a minified split build where an importing chunk's init thunk import resolved to `fs/promises.rm`. There, minification is what made the names collide: the exporting chunk had a live init thunk whose minified name was `rm`, and some file in it had a tree-shaken `import { rm } from "fs/promises"`. ## Cause For `--compile --bytecode --format=esm` the linker builds each chunk's module record itself (`post_process_js_chunk`). External imports are collected by walking the statements of every part in `parts_in_chunk_in_order`. For non-wrapped files those ranges only contain live parts, but `find_imported_parts_in_js_order` gives a wrapped file a single range covering all of its parts, and `generate_code_for_file_in_chunk_js` then skips the dead ones when printing. The record walk did not, so the dead import was recorded even though it is not in the chunk. Builtins are external-without-side-effects, so an unused builtin import is a dead part. Because the dead import's symbols were never given a name by the renamer, `name_for_symbol` returns the original source name, so the record gained an import entry `fs/promises.rm` with local name `rm`. `ModuleInfo::finalize` then saw the chunk's `export { rm }` (a local export whose local name matches an import entry) and, per the usual local-to-indirect conversion, rewrote it into an indirect export of `fs/promises.rm`. Any importing chunk resolving that export got the builtin's function. ## Fix Skip parts that `parts_live` says were tree-shaken when collecting the external imports, the same check the printer applies. A related gap in the same loop (imports that `convert_stmts_for_chunk` synthesizes from `export * as ns from "node:fs"` are printed but never recorded, so under bytecode `ns` is left in TDZ) is a separate bug and is not changed here. ## Verification `test/bundler/bundler_compile_splitting.test.ts` gains `compile/splitting/BytecodeDeadExternalImportInWrappedModule` and its `+minify` variant. The unused import also binds every single-character identifier, so the minified variant collides with whatever name the minifier gives `rm` and reproduces the reported minified shape (`import{a as r,b as o}` bound to `fs/promises.rm`). Both fail on the released binary with the `ERR_INVALID_ARG_TYPE` error above and on a debug build of `main` with the record cross-check error; both pass with this change. `bundler_compile.test.ts` (ESM bytecode matrix) and `bundler_bun.test.ts` are unchanged. --- .../linker_context/postProcessJSChunk.rs | 6 ++ .../bundler/bundler_compile_splitting.test.ts | 59 +++++++++++++++++++ 2 files changed, 65 insertions(+) diff --git a/src/bundler/linker_context/postProcessJSChunk.rs b/src/bundler/linker_context/postProcessJSChunk.rs index d78380688c32..4711471ea2b4 100644 --- a/src/bundler/linker_context/postProcessJSChunk.rs +++ b/src/bundler/linker_context/postProcessJSChunk.rs @@ -280,8 +280,14 @@ pub(crate) fn post_process_js_chunk( let source_parts = all_parts[part_range.source_index.get() as usize].as_slice(); let source_import_records = all_import_records[part_range.source_index.get() as usize].as_slice(); + // A wrapped file's range spans all of its parts, including the tree-shaken ones. + let parts_live = &c.graph.parts_live[part_range.source_index.get() as usize]; let mut part_i = part_range.part_index_begin; while part_i < part_range.part_index_end { + if !parts_live.is_set(part_i as usize) { + part_i += 1; + continue; + } // `Part.stmts: StoreSlice` — arena-backed, safe `Deref`. for stmt in source_parts[part_i as usize].stmts.iter() { match &stmt.data { diff --git a/test/bundler/bundler_compile_splitting.test.ts b/test/bundler/bundler_compile_splitting.test.ts index c2bdd9784b87..c75d514a5861 100644 --- a/test/bundler/bundler_compile_splitting.test.ts +++ b/test/bundler/bundler_compile_splitting.test.ts @@ -61,5 +61,64 @@ describe("bundler", () => { }, }); } + + // The shared chunk contains a require()d (so __esm-wrapped) module with an + // unused import of a node builtin.

Every constructor (`init_strong`, `set_strong`, `upgrade`) built it from a value, and nothing cleared it in place (the only clear was the `try_swap()` in `downgrade`, immediately followed by overwriting `*self`), so the empty states were never reachable but every reader still had to handle them. The payload is now `crate::Strong`, which always holds a value. ```rust // before use crate::strong::Optional as Strong; JsRef::Strong(strong) => strong.get(), // try_get: Option from a nullable handle JsRef::Strong(strong) => !strong.has(), // is_empty let value = strong.try_swap().unwrap_or(JSValue::UNDEFINED); // downgrade if strong.get() != Some(value) { strong.set(global, value) } // update // after use crate::{JSGlobalObject, JSValue, Strong}; JsRef::Strong(strong) => Some(strong.get()), JsRef::Strong(_) => false, let value = strong.get(); if strong.get() != value { strong.set(global, value) } ``` `init_strong`, `set_strong` and `upgrade` are textually unchanged and now resolve to `Strong::create` / `Strong::set`. `downgrade` reads the value and lets the old `Strong`'s `Drop` release the slot; `Bun__StrongRef__delete` clears the slot itself, so the separate in-place clear was redundant. No code outside this file names the `Strong` or `Weak` payloads (all 38 files using `JsRef` go through its methods), so no call sites change. Single file, 9 insertions, 11 deletions. ## Why A `JsRef` in the `Strong` state can no longer represent "strong but holding nothing"; the three states a reader has to consider are exactly the three enum variants, and `try_get()` on the `Strong` arm is `Some` by type rather than by convention. It is zero-cost: `NonNull` and `Option>` are both one pointer wide, so `JsRef` keeps its layout; the change removes a null check and an empty-slot check from `try_get` / `is_empty` / `is_not_empty` / `update` and one redundant slot store from `downgrade`, and the same two FFI calls (`Bun__StrongRef__new`, `Bun__StrongRef__delete`) happen at the same points as before. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

Real HTTP/1.0 servers (`python -m http.server`, and most other respond-and-close servers) close the socket right after the response, so in practice the pooled socket races the server's FIN: the next fetch to that origin is written onto it and only succeeds because `on_close` retries idempotent requests on reused connections. A POST loses that race with ECONNRESET. Since #37451 the hop of a followed redirect takes the 3xx's connection back out of the pool synchronously, which makes the race a certainty for an HTTP/1.0 3xx (#37522 separately gates that release on the hop being idempotent; the HTTP/1.0 default underneath is still wrong and this fix is independent of it). ### Cause `handle_response_metadata` never looks at `response.minor_version`. `allow_keepalive` starts out `true` and is only cleared by `Connection: close`, missing framing, or an upgrade, so an HTTP/1.0 response with a Content-Length falls through to HTTP/1.1's persistent default. ### Fix The `Connection` header arm now also records whether any field line carried a `keep-alive` token (`close` still clears `allow_keepalive` on the spot, so it stays sticky across lines and wins over `keep-alive`). After the header loop, an HTTP/1.0 response without such a token clears `allow_keepalive`. Why this is the right rule: RFC 9112 section 9.3 makes an HTTP/1.0 response non-persistent unless it carries `Connection: keep-alive` (that header is how HTTP/1.0 keep-alive was negotiated in the first place, and bun already sends `Connection: keep-alive` on its requests, so servers that support it will answer with it). Node's HTTP parser (`shouldKeepAlive`), undici and curl all implement the same rule; the numbers in the repro are node's. Only `Connection` is consulted: a `Keep-Alive:` parameters header on its own does not count, same as in node and curl. The check is placed after the early return for a proxy's 2xx reply to CONNECT on purpose. tinyproxy, Apache mod_proxy_connect and older Squid answer CONNECT with `HTTP/1.0 200 Connection established`; that status line describes the hop to the proxy, and since `state` is not reset between the CONNECT reply and the tunneled response, clearing `allow_keepalive` there would stop every tunnel through such a proxy from being pooled. The origin's response inside the tunnel goes through the same function later and is judged on its own version, exactly like a direct connection. The h2/h3 sessions feed a synthetic `minor_version: 0` through this function too; they already overwrite `allow_keepalive` right afterwards because HTTP/1.x persistence rules do not apply to them, and the comment there now says so. ### Tests `test/js/web/fetch/fetch-keepalive.test.ts`: - The `Connection: close` table is generalised to status line + header lines + expected connection count and gains HTTP/1.0 rows: no Connection header (200 and 404), `Keep-Alive:` header alone, `Connection: keep-alive` (both spellings, still pooled), and `keep-alive` combined with `close` on one line or across two lines in either order (still not pooled). HTTP/1.1 without a Connection header is pinned as still pooled. - A CONNECT-proxy table: `HTTP/1.0 200` CONNECT reply with an HTTP/1.1 origin still pools the tunnel, so does an HTTP/1.0 origin that says keep-alive, and an HTTP/1.0 origin without it makes each fetch open a new tunnel. - The redirect table gains an HTTP/1.0 302 (hop and later fetches dial again, like the `Connection: close` row) and an HTTP/1.0 302 with `Connection: keep-alive` (one connection throughout). Without the `src/http/lib.rs` change, main fails exactly the five rows that describe the bug (three direct, the HTTP/1.0-origin tunnel row and the HTTP/1.0 302 row, each with one connection instead of 4 / 3 / 5); with it all 36 tests in the file pass. `fetch-redirect`, `fetch-connection-header`, `fetch-url-after-redirect`, `fetch-proxy-connect-tunnel-split-envelope`, `fetch-http2-client`, `fetch-http3-client`, `client-fetch`, `proxy.test.ts`, `proxy-stress-protocol` (which has an HTTP/1.0-origin-through-tunnel group), `proxy-stress-matrix` and `proxy-stress-concurrent` pass on the debug build as well. Note: #37522 rewrites the redirect section of the same test file; whichever of the two lands second needs its two HTTP/1.0 redirect rows moved over. The `lib.rs` changes do not overlap. This is the half of #35545 that #36370 did not pick up. --- src/http/lib.rs | 19 +- test/js/web/fetch/fetch-keepalive.test.ts | 205 ++++++++++++++++++---- 2 files changed, 186 insertions(+), 38 deletions(-) diff --git a/src/http/lib.rs b/src/http/lib.rs index 0c878cfc9b28..8518adb645ef 100644 --- a/src/http/lib.rs +++ b/src/http/lib.rs @@ -418,7 +418,9 @@ impl HTTPClient<'_> { }; let should_continue = self.handle_response_metadata(&mut response)?; // h2/h3 framing delimits the body; chunked transfer-encoding and the - // HTTP/1.1 "no Content-Length ⇒ no keep-alive" rule don't apply. + // HTTP/1.x persistence rules (no Content-Length ⇒ no keep-alive, and the + // HTTP/1.0 default that the synthetic `minor_version: 0` above trips) + // don't apply. self.state.transfer_encoding = Encoding::Identity; if self.state.response_stage == ResponseStage::BodyChunk { self.state.response_stage = ResponseStage::Body; @@ -4790,6 +4792,7 @@ impl<'a> HTTPClient<'a> { let mut pretend_304 = false; let mut is_server_sent_events = false; let mut content_codings: u32 = 0; + let mut has_keep_alive_token = false; for (header_i, header) in response.headers.list.iter().enumerate() { match hash_header_name(header.name()) { h if h == hash_header_const(b"Content-Length") => { @@ -4885,8 +4888,10 @@ impl<'a> HTTPClient<'a> { } h if h == hash_header_const(b"Connection") => { // `close` on any field line, any status, is sticky (RFC 9110 §5.3, RFC 9112 §9.6). - if connection_header_keep_alive(header.value()) == Some(false) { - self.state.flags.allow_keepalive = false; + match connection_header_keep_alive(header.value()) { + Some(false) => self.state.flags.allow_keepalive = false, + Some(true) => has_keep_alive_token = true, + None => {} } } h if h == hash_header_const(b"Last-Modified") => { @@ -4975,6 +4980,14 @@ impl<'a> HTTPClient<'a> { is_proxy_connect_failure = true; } + // RFC 9112 §9.3: an HTTP/1.0 response is non-persistent unless it says + // `Connection: keep-alive`.

Deleted its arm, both `EnsureRouteCtx::on_failure` impls (which would have `unwrap`ed the always-`None` `Framework.evaluate_failure` field), the field, and `ErrorPageKind` (every live caller passed `Bundler`, so the page title is now a constant). - `MessageId::{BrowserMessage,BrowserMessageClear,RequestHandlerError}`: wire bytes the server never sends and no client handles. `generated.ts` regenerated via the bake codegen. ### sql - mysql `CommandType`: kept the three commands bun sends (`COM_QUERY`, `COM_STMT_PREPARE`, `COM_STMT_EXECUTE`); the other 28 had zero references. The enum is only used as `as u8` in packet writers, no decode path. - mysql `StatusFlag`: kept `SERVER_MORE_RESULTS_EXISTS` (the only flag `StatusFlags::has` is asked about). Decode is unaffected; `StatusFlags` stores the raw `u16`. - Never-constructed error variants and their arms: mysql `InvalidState`, postgres `InvalidByteSequenceForEncoding` and `InvalidTimeFormat`. These names are also not producible via the `EnumString` reverse parse in `From` (no other sql error enum carries them). Postgres `Overflow` stays: mysql's constructed `Overflow` could reach it through that by-name parse. ### install / cli - `Subcommand::Scan` plus its two arms (28 lines of help text): `bun pm scan` dispatches under `Subcommand::Pm`. - `Step::{Copyfile,Linking,Patching}`: `InstallResult::fail` is only called with the other four variants. - The lifecycle script time log: the entry struct was empty, the list was never read, and the `timer` field feeding it was never set to `Some`, so the whole chain (structs, `append_concurrent`, the `PackageManager` field, the timer field, `manager_mut`) was a write-only no-op left from the port. - `PackageInstall.file_count` carried a literal "TODO: this is never read" comment; error handling at the four assignment sites is preserved. - `PackError::MissingPackageJSON` (never constructed; the live same-named variants are on different enums) and `ExampleTag::Unknown` (zero references; the compiler confirmed by flagging the `_ => unreachable!()` arm as unreachable once it was gone). ### css / websocket / subprocess / timer / watcher / C++ / js - css `crate_error::Error::CSSPrintError` (never constructed; the live `CSSPrintError` spellings are the separate `PrintErr` enum) and two uncalled inherent `parse_with_options` helpers on `GenericSelectorList`/`GenericSelector`. - websocket `ErrorCode::{HeadersTooLarge,CompressionFailed,ExpectedControlFrame,ProtocolError,ProxyConnectionRefused}`: never constructed. Discriminants are explicit, so the remaining values still line up with the C++ `WebSocketErrorCode` table. - `WTFTimer__runIfImminent`: an `extern "C"` export with zero references in C++, vendor/WebKit, or codegen (the imminent-GC path runs via `__bun_run_wtf_timer`). - Subprocess `Readable::{on_close,on_ready}` / `Writable::on_ready` stubs with no callers (teardown goes through `Subprocess::on_close_io` and the `UpstreamSource` impl). - fs-watcher `EventType::Abort` was never sent (C++ `EventNames.cpp` keeps its by-value string table entry). - C++ `KeyObject::getKeyObjectFromHandle`: declaration + definition pair with zero callers. - js: two unread repl `internalBinding('util')` shim constants and a write-only minimatch debug property. - Cargo.toml: unused boilerplate deps in `bun_glob`/`bun_router` and bundler's unused `bun_router` dependency; a dead root re-export in `bun_s3_signing`. ### Verification - `cargo check` via `bun run rust:check-all`: 10 ok, 0 failed. - Full `bun bd` debug build. - `bun bd test` on the touched areas: `bunshell.test.ts` (418 pass), shell command tests, `bun-pack.test.ts` (76 pass), `bun-install-lifecycle-scripts.test.ts` (115 pass), websocket permessage-deflate, `css.test.ts` (1209 pass), `bake/dev/esm.test.ts`, `repl.test.ts` (148 pass), `glob/match.test.ts`, `fs.watch.test.ts`, spawn exit-code/stream tests. The only local failures are container artifacts (tests running as root, tests hitting external websocket endpoints, and PATH shims that expect a binary literally named `bun`), identical under the released bun. - Adds `test/internal/source-lints/dead-symbols-shell-bake-sql-install.test.ts` pinning every removal so the symbols do not come back. Follow-up note (not in this diff): `bun_install::npm` decodes a manifest `file_count` that may also be write-only, and the shell `PromptBehaviour::Once { removed_count }` field is written but unread pending `-i` support; both left alone as plausible in-flight scaffolding. --- **[review]** gate passed · iteration 3 · 47 files touched

Each of these fields has a constructor in its own module that establishes something about it, and each was `pub`/`pub(crate)` even though no code outside that module reads or writes it. Dropping the visibility costs nothing today and means a future write from elsewhere has to go through the module that knows the rule: - `Tmpfile.{destination_dir, tmpfilename}`: `finish()` renames exactly the pair `create` opened. - `KEventWaker.{kq, machport}` (macOS): `init` rejects `machport == 0`; `wake`/`wait` are the only readers. - `DynamicBitSetList.{n, bit_length}`: they size the raw buffer that `at()` does pointer arithmetic on. - `webcore::Response.{ref_count, weak_ptr_data}`, `Request.reported_estimated_size`: maintained only by their own `ref_`/`unref`/`estimated_size` methods. - `EVP.md`: `init` rejects a null digest. - `PBKDF2.algorithm`: `from_js` rejects digests without an `md()`, and `run()` unwraps it. - `UDPSocketConfig.{connect, fd}` and `ConnectConfig`'s fields: `from_js` range-checks the port and rejects a negative fd before they reach usockets. - `FileSystemFlags.0`: every construction already goes through `from_js`/the named constants. No behavior change; visibility only. ### How did you verify your code works? `cargo check -p bun_sys -p bun_io -p bun_collections -p bun_runtime` is clean, which is the whole claim: nothing outside these modules used the fields. --- src/collections/bit_set.rs | 4 ++-- src/io/lib.rs | 4 ++-- src/runtime/crypto/EVP.rs | 2 +- src/runtime/crypto/PBKDF2.rs | 2 +- src/runtime/node/types.rs | 2 +- src/runtime/socket/udp_socket.rs | 8 ++++---- src/runtime/webcore/Request.rs | 2 +- src/runtime/webcore/Response.rs | 4 ++-- src/sys/tmp.rs | 4 ++-- 9 files changed, 16 insertions(+), 16 deletions(-) diff --git a/src/collections/bit_set.rs b/src/collections/bit_set.rs index 9d326d8715aa..8e68e97f19ec 100644 --- a/src/collections/bit_set.rs +++ b/src/collections/bit_set.rs @@ -847,8 +847,8 @@ impl DynamicBitSetUnmanaged { pub struct DynamicBitSetList { buf: ptr::NonNull, buf_len: usize, - pub(crate) n: usize, - pub(crate) bit_length: usize, + n: usize, + bit_length: usize, } impl DynamicBitSetList { diff --git a/src/io/lib.rs b/src/io/lib.rs index e17d52e9384b..7c95b130eaea 100644 --- a/src/io/lib.rs +++ b/src/io/lib.rs @@ -2011,8 +2011,8 @@ pub mod waker { #[cfg(target_os = "macos")] pub struct KEventWaker { - pub(crate) kq: i32, - pub(crate) machport: bun_core::mach_port, + kq: i32, + machport: bun_core::mach_port, pub machport_buf: Box<[u8]>, } diff --git a/src/runtime/crypto/EVP.rs b/src/runtime/crypto/EVP.rs index 3986fb5371ce..c9df87495e7a 100644 --- a/src/runtime/crypto/EVP.rs +++ b/src/runtime/crypto/EVP.rs @@ -9,7 +9,7 @@ use crate::jsc::JSGlobalObject; pub struct EVP { pub ctx: boringssl::EVP_MD_CTX, // FFI: BoringSSL EVP_MD singletons are static for the process lifetime. - pub(crate) md: *const boringssl::EVP_MD, + md: *const boringssl::EVP_MD, pub(crate) algorithm: Algorithm, } diff --git a/src/runtime/crypto/PBKDF2.rs b/src/runtime/crypto/PBKDF2.rs index 66e94459374f..e70ffa4f1a70 100644 --- a/src/runtime/crypto/PBKDF2.rs +++ b/src/runtime/crypto/PBKDF2.rs @@ -15,7 +15,7 @@ pub(crate) struct PBKDF2 { pub salt: StringOrBuffer, pub iteration_count: u32, pub length: i32, - pub algorithm: Algorithm, + algorithm: Algorithm, } impl PBKDF2 { diff --git a/src/runtime/node/types.rs b/src/runtime/node/types.rs index 12f682ee117f..1cafda42a21c 100644 --- a/src/runtime/node/types.rs +++ b/src/runtime/node/types.rs @@ -1575,7 +1575,7 @@ impl PathOrFdExt for PathOrFileDescriptor { /// Non-exhaustive set of flag values; newtype over c_int. #[repr(transparent)] #[derive(Copy, Clone, PartialEq, Eq)] -pub struct FileSystemFlags(pub c_int); +pub struct FileSystemFlags(c_int); #[derive(Copy, Clone, PartialEq, Eq)] pub enum FileSystemFlagsKind { diff --git a/src/runtime/socket/udp_socket.rs b/src/runtime/socket/udp_socket.rs index 8c8b8367f18e..d82883f8695e 100644 --- a/src/runtime/socket/udp_socket.rs +++ b/src/runtime/socket/udp_socket.rs @@ -313,19 +313,19 @@ extern "C" fn on_data( } pub struct ConnectConfig { - pub(crate) port: u16, - pub(crate) address: BunString, + port: u16, + address: BunString, } pub struct UDPSocketConfig { pub(crate) hostname: BunString, - pub(crate) connect: Option, + connect: Option, pub(crate) port: u16, pub(crate) flags: i32, /// Adopt this already-created (and usually bound) socket descriptor /// instead of creating a new one.

The field docs justified the `'static`s with "a real lifetime would infect every `Printer<'a, ..>` instantiation", but `Printer` already has that `'a`, and the table arrives as `Options<'a>.line_offset_tables: Option<&'a List>`. The builder is now `NewBuilder<'a, T>` (`pub type Builder<'a>`) with one field describing the table and its owner, plus the caches typed as what they are: ```rust // before pub line_offset_tables: ManuallyDrop>, pub lazy_line_offset_tables: Option, pub deferred_source: Option<(&'static [u8], i32)>, pub line_offset_table_byte_offset_list: &'static [u32], pub line_offset_table_first_non_ascii: &'static [u32], // after pub enum LineOffsetTables<'a> { None, Borrowed(&'a line_offset_table::List), Deferred { contents: &'a [u8], approximate_line_count: i32 }, Owned(OwnedLineOffsetTables), } pub line_offset_tables: LineOffsetTables<'a>, pub line_offset_table_byte_offset_list: bun_ptr::RawSlice, pub line_offset_table_first_non_ascii: bun_ptr::RawSlice, ``` `add_source_mapping` keeps its structure: the first mapping replaces `Deferred` with `Owned(generate(..))`, and its three dispatches between the two tables (`len`, the two `u32` columns filled into the caches, and the rare `columns_for_non_ascii` row) become three small private methods on the enum; the caches are filled with `RawSlice::new` and read with `slice()`. `get_source_map_builder<'a>` now takes `&mut Options<'a>` and `&'a Source` and writes the variant directly: `Borrowed` from `opts.line_offset_tables.take()`, `Deferred` for the runtime (`Lazy`) mode, `None` otherwise. `Printer.source_map_builder` and `Printer::init` take `Builder<'a>`; `print`, `print_with_writer` and `print_with_writer_and_platform` take `source: &'a Source` so the `Deferred` borrow is checked rather than asserted (their 5 callers in `bun_bundler` compile unchanged; `print_ast` already had it). Deleted because the change makes them dead: `set_deferred_line_offset_table` (its only caller now builds the variant), the three replaced fields and their docs, the cache reset in the `Deferred` transition (the transition is the first thing the first mapping does, so the caches are necessarily still empty), and the `Printer::init` / `print_ast` comments describing the `'static` fields and the `ManuallyDrop` alias. Removes 4 `unsafe` blocks (the `ptr::read` and three `from_raw_parts`) and adds none. 2 files, 125 insertions, 187 deletions. ## Why Who owns the table and which states exist are now answerable from the type: `Borrowed` is the linker's and is never freed here, `Owned` is freed with the builder through `OwnedLineOffsetTables::drop`, `Deferred` holds a borrow that the compiler checks against the same `'a` the printer already carries, and the impossible combinations the old fields allowed (a precomputed table plus a deferred source, or both tables populated) cannot be written. The `'a` is the existing `Options<'a>` lifetime, so no caller changes; `LineOffsetTables<'a>` is 32 bytes where the three fields it replaces were 72 (`Builder` goes from 1560 to 1520 bytes); `RawSlice` is `#[repr(transparent)]` over a fat pointer, so the cached columns are still one ptr+len read; per mapping, the enum tag check and match replace the `Option` checks on `lazy_line_offset_tables` and `deferred_source`, the caches are still filled once, and building the builder stores one pointer instead of copying a 24-byte list header. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

It counted them by hand with `claims: Cell`, `acquire_claim()` and `release_claim() -> bool`, and each of the five release sites read the bool and freed the `Box` itself: `finalize` leaked or dropped the `Box`, `abandon_suspension` and both `.then()` reactions called `heap::destroy` in their own `unsafe` blocks, and `release_pump_claim` dropped the count to zero and scheduled a `Tag::HTMLRewriterPipeFree` task whose arm was another `heap::destroy` (`src/runtime/api/NativePromiseContext.rs`). The struct now derives `bun_ptr::CellRefCounted` (`ref_count: Cell`), the same primitive `TextChunk`, `DocType`, `Comment`, `EndTag`, `DocEnd`, `Element` and `AttributeIterator` already use in this file. The two acquire sites (`wire_input`, `begin_suspension`) are `ref_()`, the three inline release sites are `deref_nn`, `finalize` is `bun_ptr::finalize_js_box(this, |pipe| pipe.cell.set(JSValue::ZERO))`, the wrapper-allocation failure path in `init` drops the initial ref with `deref_nn` instead of `destroy_box_with`, and the deferred task arm is a `deref_nn` like the request-context arms beside it. The existing `impl Drop for RewriterPipe` is unchanged; the derive's default `destroy` drops the `Box`, which is what every removed free site did. ```rust // before if !this.release_claim() { // SAFETY: last owner ... unsafe { bun_core::heap::destroy(pipe.as_const_ptr().cast_mut()) }; } // after Self::deref_nn(pipe.into()); ``` `release_pump_claim` becomes `release_pump_ref` and keeps deferring the final release to the event loop, because the C++ caller keeps using the allocation in the same frame; when other refs remain it calls `deref_nn` inline, and when it holds the last ref it leaves that ref to the task instead of zeroing the count and deferring the free. The `HTMLRewriterPipeFree` tag keeps its name and discriminant, so `NativePromiseContext.h` is untouched. Removes 3 `unsafe` blocks and the two bespoke helpers; two files, +43/-79 lines. ## Why Who owns a `RewriterPipe` and when it is freed is now stated by the standard refcount type rather than by a `bool` that each caller had to interpret correctly, and the "count is zero but the allocation is still in use" window in the pump-detach path no longer exists. It is zero-cost: `ref_()` and `deref_nn` are the same `Cell` increment and decrement-and-branch the removed helpers compiled to, no path gains an allocation, task or check, and the deferred-release path schedules the same task at the same point. Widening the count from `Cell` to `Cell` moves `size_of::()` from 264 to 272 bytes; both sizes are served from the same 320-byte mimalloc size class, so the heap block allocated per `transform()` is unchanged. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

Two fields whose owner sets them up under a specific condition were writable from anywhere in the crate: - `webcore::Request.signal` is only ever set from `construct_into` (after `AbortSignal::ref_from_js` type-checks it), `clone_into`, and the lazy `signal` getter. Its one outside reader, `fetch()` extracting the signal from a `Request` argument, now goes through `Request::abort_signal()`, and the field is private. - `JSArrayIterator.fast`/`.array` are `Some`/set only when C++ reported a contiguous butterfly together with the `len` that `next()` bounds against; `Blob`'s parts loop read `fast` to decide whether iteration can run JS. That is now `iter.is_fast()`, and both fields are private (`i`/`len` stay public, they are read widely and `next()` bounds-checks `i`).

All 5 constructor sites (`ParseTask::init`, `enqueue_entry_points_common`, `enqueue_parse_task2`, the onResolve task literal in `on_resolve`, `process_resolve_queue`) filled both from one pointer, and the 2 placeholder sites (`Default`, the runtime source) set both to `None`. ```rust // before pub ctx: Option>>, pub completion_ctx: Option, bun_ptr::Mut>>, // after (same shape as ServerComponentParseTask::ctx) pub ctx: Option, bun_ptr::Mut>>, ``` The constructor sites now assign one field; the onResolve literal built the pointer twice in two `unsafe` blocks and now builds it once, removing 1 `unsafe` block. The 3 readers are unchanged apart from the field name: `ctx()` still projects `&BundleV2` through `ParentRef::get`, and `run_from_thread_pool_impl` (building `Result`) and `Load::on_defer` in `JSBundler.rs` take their write-provenance copy from the same field. `ParentRef::shared` in `bun_ptr` had these constructors as its only callers and is deleted. ## Why The type no longer admits a task whose two bundle pointers disagree or where only one is set; there is one back-reference, and the `Mut` marker on it records that completion writes through it. `Option>` is `repr(transparent)` over `NonNull` with the `None` niche, so `ParseTask` only loses one pointer-sized field; `ParentRef::get` is the same dereference for both markers and the number of `expect` checks on each path is unchanged.

Its only producer (`MySQLQuery::bind_and_execute_impl`) filled the two `fn` pointers with thunks that each did `unsafe { *ctx.cast::().add(i) }`, relying on the `len` passed alongside the pointer to keep `i` in bounds. ```rust // before pub struct ExecuteParams<'a> { pub len: usize, pub ctx: *mut c_void, pub is_null: fn(*mut c_void, usize) -> bool, pub to_data: fn(*mut c_void, usize, FieldType) -> Result, pub _marker: PhantomData<&'a ()>, } // after pub trait ExecuteParam { fn is_null(&self) -> bool; fn to_data(&self, field_type: FieldType) -> Result; } pub struct Execute<'a, P: ExecuteParam> { /* unchanged fields */ pub params: &'a [P], } ``` `Execute::write` now iterates `params` directly: `enumerate()` for the null bitmap and `zip(param_types)` for the values (the `debug_assert_eq!` on the two lengths stays). The 3 hook invocations in `PreparedStatement.rs` become plain method calls. `Value` implements `ExecuteParam` next to its definition in `MySQLValue.rs`: `is_null` is `matches!(self, Value::Null)` and the existing inherent `to_data`, which had no other caller, becomes the trait method with its body unchanged. The single construction site in `MySQLQuery.rs` passes `params: ¶ms`. `ExecuteParams`, both thunks and their 2 unsafe blocks, and the now unused `c_void`, `PhantomData`, `FieldType` and `any_mysql_error` imports are deleted. ## Why The protocol crate still cannot name `Value` (it lives in the higher-tier `bun_sql_jsc`), but the element type and the bound of the parameter array are now carried by `&[P]` instead of a raw pointer, a separate `len` field and a SAFETY comment, so no `unsafe` is left on the parameter encoding path. This is zero-cost: `Execute::write` is monomorphised exactly once (`P = Value`), so the two indirect calls per parameter become direct calls; `&[P]` is the same pointer and length pair `ExecuteParams` carried (the stack-local `Execute` shrinks by the two function pointers); nothing is allocated or copied, and the loops gain no per-element checks (`zip` is bounded by the two lengths that `MySQLQuery::bind` already guarantees equal). Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

The only constructor, in `TestCommand::exec` (`src/runtime/cli/test_command.rs`), declared the four containers as stack locals whose only use was to be laundered to `'static` with four `bun_ptr::detach_lifetime_mut` calls and stored into the struct literal. The struct also cached the directory of the current snapshot file as an `Option>` and read it back through `unsafe { p.as_ref() }`. ```rust // before pub struct Snapshots<'a> { pub(crate) file_buf: &'a mut Vec, pub(crate) values: &'a mut HashMap>, pub(crate) counts: &'a mut StringHashMap, pub(crate) snapshot_dir_path: Option>, pub(crate) inline_snapshots_to_write: &'a mut IndexMap>, .. } // after pub struct Snapshots { file_buf: Vec, values: HashMap>, counts: StringHashMap, snapshot_dir_path: Option<&'static [u8]>, inline_snapshots_to_write: IndexMap>, .. } impl Snapshots { pub(crate) fn init(update_snapshots: bool) -> Snapshots { .. } } ``` `TestCommand::exec` now writes `snapshots: Snapshots::init(ctx.test_options.update_snapshots)` in place of the four locals and the 22 line struct literal, and drops the imports that only served those locals. `TestRunner<'a>` keeps its lifetime for `concurrent_test_glob` and `test_options`; its `snapshots` field is now plain `Snapshots`. Inside `snapshot.rs` every existing access to the four containers compiles unchanged except one, which becomes `write_all(&self.file_buf)`; the `snapshot_dir_path` read becomes a plain copy of the field and its two writes become `Some(dir_path)`. The counters still read from `expect.rs` and the summary printer (`update_snapshots`, `total`, `added`, `passed`, `failed`, `last_error_snapshot_name`) stay `pub(crate)`; the six fields only `snapshot.rs` touches become private. Removes 5 unsafe blocks (4 in `test_command.rs`, 1 in `snapshot.rs`) together with their SAFETY comments; adds none. ## Why The containers are owned by `Snapshots` and live exactly as long as the `TestRunner` that embeds it, and the type now says so instead of a never-returning-frame argument repeated in four SAFETY comments. `snapshot_dir_path` is assigned from `Source::path.name().dir_with_trailing_slash()`, and `bun_ast::Source::path` is a `Path<'static>`, so `&'static [u8]` is the type the value already had; the `NonNull` only hid it. Zero-cost: the same four containers exist as before, now inline in the process-singleton `TestRunner` instead of one pointer away, and `Option<&'static [u8]>` has the same two-word layout and the same loads and stores as `Option>`. No runtime checks are added and nothing here crosses FFI.

To satisfy that signature, the HTML compile task recovered a raw pointer from the shared context (`let chunks: *mut [Chunk] = ctx.chunks.as_ptr();`), stored it in `HTMLLoader.chunks: *mut [Chunk]`, threaded it through `generate_compile_result_for_html_chunk_impl`, and materialised `unsafe { &mut *self.chunks }` in both `standalone_body_script` and `get_head_tags`. The SAFETY comments claimed that was the sole live `&mut`, which is not the case: this callback runs on the worker pool, one task per HTML chunk, concurrently with the JS/CSS part-range tasks holding views into their own elements of the same slice and with any other HTML task doing the same thing. ```rust // before pub(crate) fn get_js_chunk_for_html<'a>(&self, chunks: &'a mut [Chunk]) -> Option<&'a mut Chunk> pub(crate) fn get_css_chunk_for_html<'a>(&self, chunks: &'a mut [Chunk]) -> Option<&'a mut Chunk> struct HTMLLoader<'a> { chunk: bun_ptr::BackRef, chunks: *mut [Chunk], .. } // after pub(crate) fn get_js_chunk_for_html<'a>(&self, chunks: &'a [Chunk]) -> Option<&'a Chunk> pub(crate) fn get_css_chunk_for_html<'a>(&self, chunks: &'a [Chunk]) -> Option<&'a Chunk> struct HTMLLoader<'a> { chunk: &'a Chunk, chunks: &'a [Chunk], .. } ``` - Both helpers iterate with `iter()` and return shared references. The labelled block in `get_css_chunk_for_html` existed only to copy the CSS index out before re-borrowing mutably; it is now a direct `return Some(&chunks[css_idx as usize])` with the same fallback behaviour (the `break` keeps the old "stop at the first matching JS chunk, then fall back" control flow). - The task callback takes `ctx.chunks.get()` next to the existing `ctx.c.get()` / `ctx.chunk.get()` and passes plain references to `generate_compile_result_for_html_chunk_impl(c, chunk: &'a Chunk, chunks: &'a [Chunk])`. `HTMLLoader` stores both as `&'a` borrows (the `chunk` field was a lifetime-erased `BackRef` with a comment describing the lifetime that the type now states), and the 4 call sites become `self.chunk.get_..._chunk_for_html(self.chunks)`. Removes 2 unsafe blocks and the `as_ptr()` recovery. - With no remaining writer through it, `GenerateChunkCtx.chunks` (`src/bundler/LinkerContext.rs`) is narrowed from `BackRef<[Chunk], Mut>` to `BackRef<[Chunk]>`; its two construction sites in `generateChunksInParallel.rs` become `BackRef::new(&*chunks)`. The other readers (`postProcessJSChunk`, `postProcessCSSChunk`, `postProcessHTMLChunk`) already used the safe `Deref`. Per-task writes keep going through `GenerateChunkCtx.chunk` (still `BackRef`) and the `*mut Chunk` that `each_ptr` hands out. ## Why The HTML task now holds the same kind of view of the chunk list that the CSS task and the post-process tasks already hold, a shared borrow for the duration of the task, and the context type says that nothing writes through `chunks`; the two unsafe blocks whose justification was false are gone. Only reference mutability and lifetimes change: the lookups compile to the same loops and the same `unique_key` loads (the `first()` check replaces an `is_empty()` plus index), `&[Chunk]`, `*mut [Chunk]` and `BackRef<[Chunk]>` are all one fat pointer, so `HTMLLoader` and `GenerateChunkCtx` keep their layout, and no check, allocation or indirection is added on any path.

The already-handled check becomes `default_files_loaded.contains(env_file)` and the three "prevent retrying" / done writes become `insert(env_file)`. `print_loaded` iterates the set (the enum is declared in the order the old `ALL` table had, and `EnumSet` iterates in declaration order) and uses `len()` for the count, so its output is unchanged; the `ALL` table, the `[bool; 8]`, `default_file_slot` and its `unreachable!()` are deleted. The two `custom_files_loaded.put(path, Source::default())` calls become `StringSet::insert(path)` (the existing `bun.StringSet` type in `bun_collections`, a `StringArrayHashMap<()>`). `bun_ast` is removed from `src/dotenv/Cargo.toml` (and the matching line from `Cargo.lock`); these placeholders were the crate's only use of it. ## Why The set of files the loader can track is now closed at the type level: `load_env_file` can only be asked about one of the eight known files, so the filename-to-field mapping and its unreachable arm no longer exist, and the print order is the enum declaration order rather than a second copy of the filename list. It is zero-cost in the strict sense: `EnumSet` is a `repr(transparent)` `u8` replacing eight `Option` fields of 112 bytes each; marking a file done is a bit-or instead of filling in a 112-byte placeholder struct; `StringSet` keeps the same key boxing and lookup as before and simply has no values column to fill. `name()` is a `match` returning the same static slices the callers used to pass in. Nothing outside `env_loader.rs` referenced any of the removed items (all were `pub(crate)` with no other users), and `bun_dotenv` drops `bun_ast` from its dependency graph. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

The variant docs record who owns the pending context (uWS, one per `.ws()` route, outliving the request), which previously lived in a comment at the deref site. The `usize::MAX` sentinel no longer appears in the server module. ## Why The magic pointer value and the state "upgraded but still carrying a handshake pointer" are now unrepresentable, and the ownership of the pending pointer is stated on the type that holds it instead of at one use site. This is zero-cost: `Option<*mut T>` has no niche and is a tag plus a pointer, and the new enum (two dataless variants plus one `NonNull` payload) has the same 16 byte, align 8 layout, so the pooled `RequestContext` size is unchanged; each discriminant test replaces one pointer compare, and the `.unwrap()` branch disappears. No FFI signature changes; `WebSocketUpgradeContext` stays the same opaque handle on both sides of the `resp.upgrade()` call. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

Every consumer then re-established ownership by hand: `enqueue_git_clone`, `enqueue_git_checkout` and `generate_network_task_for_tarball` did `unsafe { heap::take(pt) }` straight back into the `Option>` fields that `Task` and `NetworkTask` already have; `PackageInstaller` and `generate_network_task_for_tarball` dereferenced the pointer to set `install_context` / `task_id`; the isolated installer's `apply_package_patch` defined a local `PatchTaskGuard` Drop type around `PatchTask::destroy` just to use the task synchronously; `ResolvedPackageTask::PatchTask(*mut PatchTask)` was read through `unsafe { &(*patch_task).callback }`; and `enqueue_patch_task` / `enqueue_patch_task_pre` were `unsafe fn`s whose only unsafe operations were reading `.callback` and writing `.pre` through the pointer before pushing it into `patch_task_fifo`. ```rust // before pub(crate) fn new_apply_patch_hash(..) -> *mut PatchTask pub unsafe fn enqueue_patch_task(this: &mut PackageManager, task: *mut PatchTask) pub unsafe fn enqueue_patch_task_pre(this: &mut PackageManager, task: *mut PatchTask) PatchTask(*mut PatchTask), // ResolvedPackageTask // after pub(crate) fn new_apply_patch_hash(..) -> Box pub fn enqueue_patch_task(this: &mut PackageManager, task: Box) pub fn enqueue_patch_task_pre(this: &mut PackageManager, mut task: Box) PatchTask(Box), // ResolvedPackageTask ``` Both constructors now return the `Box`. The two enqueue functions log `task.callback.tag_name()`, set `task.pre` through the `Box`, and call `heap::into_raw` only at the point where the pointer is written into `patch_task_fifo`; the fifo itself stays `*mut PatchTask` and the `heap::take` in `run_tasks` remains the single reclaim point (its SAFETY comment now names the `into_raw` site). The three `apply_patch_task` producers become `let mut pt = PatchTask::new_apply_patch_hash(..); ...; Some(pt)`, `PackageInstaller` sets `install_context` through the `Box` and passes it to `enqueue_patch_task`, `apply_package_patch` holds the `Box` in a local and `PatchTaskGuard` is deleted, and the `ResolvedPackageTask::PatchTask` arm reads `patch_task.callback` directly. The 6 `enqueue_patch_task*` call sites lose their `unsafe` wrappers. In total this removes 17 unsafe blocks, 3 `unsafe fn` signatures and `PatchTask::destroy`, which had no remaining caller. 6 files, net 58 lines removed. ## Why Ownership of a freshly built `PatchTask` is now carried by `Box` from the constructor to whichever of the three owners it ends up in (a `Task` / `NetworkTask` field, a synchronous local, or the fifo), so the only remaining raw-pointer span is the fifo / thread-pool / `patch_task_queue` hand-off, bracketed by `heap::into_raw` in the two enqueue functions and `heap::take` in `run_tasks`. `Box` and `*mut PatchTask` are the same single non-null pointer, `heap::into_raw` and the removed `heap::take` calls compile to nothing, and the `ResolvedPackageTask` variant keeps its size, so the allocation count and the value pushed into the fifo are byte-for-byte unchanged. The one behavioural difference is that a task built for a package whose preinstall state moved on before it could be enqueued (the fall-through in `enqueue_dependency_with_main_and_success_fn` and in `run_from_main_thread_calc_hash`) is now dropped instead of leaked. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

The table was a separate `saved_source_map_table` field on `VirtualMachine` (documented as "do not access this field directly"), `SavedSourceMap` held a `pub map: *mut HashTable` pointing at it, `VirtualMachine::init` wrote both fields and then patched the pointer in by hand, and `Default` produced a `SavedSourceMap` with a null `map`. All 11 table accesses in the file went through `map_mut()`, a `debug_assert!(!null)` plus `unsafe { &mut *self.map }`, and `Drop` had to `deinit()` the sibling table in place so the VM's copy would not be freed twice. ```rust // before pub struct SavedSourceMap { pub map: *mut HashTable, // points at vm.saved_source_map_table pub(crate) mutex: Mutex, } fn map_mut(&mut self) -> &mut HashTable { unsafe { &mut *self.map } } // after #[derive(Default)] pub struct SavedSourceMap { map: HashTable, mutex: Mutex, } ``` Nine of those accesses now read `self.map` directly; the other two were the `unlock_pointers()` and `deinit()` calls at the end of `Drop`, which are deleted together with `map_mut()` itself (removes 1 unsafe block) and the double-free comment, since `Drop` now only releases the stored values under the mutex and the table frees its own storage afterwards. In `VirtualMachine.rs` the `saved_source_map_table` field, its `HashTable::default()` write and the backref assignment in `init` are deleted; the single `source_mappings.write(SavedSourceMap::default())` remains, and the `destroy()` comment is updated. `HashTable` becomes a private alias since the VM field was its only outside user. The 10 users of `vm.source_mappings` outside these two files (6 in `bun_runtime` and `bun_sourcemap_jsc`, 4 elsewhere in `bun_jsc`) only call methods and are unchanged. ## Why Ownership of the table is now stated by the field type: a `SavedSourceMap` always has a valid (possibly empty) table, so the null-`map` state that `Default` used to produce, and that `mem::take` in `destroy()` left behind in the VM, is no longer representable, and the lifetime comment on `map_mut()` is replaced by ordinary field access. It is zero-cost: the table moves from one VM field into the adjacent one (the VM shrinks by one pointer), each access loses a pointer load and a debug assertion, `Default` and `Drop` do the same work they did before (`deinit()` was already `*self = Self::default()`), and `init` already wrote both fields with `ptr::write`, so no new checks, allocations or copies are introduced. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates. bun bd test test/js/bun/sourcemap/internal-sourcemap.test.ts: 6 pass, 0 fail; test/js/bun/sourcemap/negative-vlq-mapping.test.ts: 10 pass, 0 fail; test/cli/test/coverage.test.ts: 12 pass, 0 fail. test/js/web/workers/worker.test.ts: 33 pass, 3 fail on this branch and identically on main with the debug build (pre-existing, timing-sensitive "terminate() races and lifecycle edges" tests: message flood, preload with un-awaited import(), fs.readFile completions), so unrelated to this change. --- src/jsc/SavedSourceMap.rs | 75 +++++++++++---------------------------- src/jsc/VirtualMachine.rs | 12 +------ 2 files changed, 21 insertions(+), 66 deletions(-) diff --git a/src/jsc/SavedSourceMap.rs b/src/jsc/SavedSourceMap.rs index bf6234c61631..7edf2e3ad7d0 100644 --- a/src/jsc/SavedSourceMap.rs +++ b/src/jsc/SavedSourceMap.rs @@ -1,7 +1,6 @@ #![warn(unused_must_use)] use core::ffi::c_void; -use core::ptr; use std::sync::Arc; use bun_collections::{HashMap, IdentityContext, TaggedPtrUnion}; @@ -13,47 +12,23 @@ use bun_sourcemap::{self as SourceMap, InternalSourceMap, ParsedSourceMap}; use bun_threading::Mutex; use bun_wyhash::hash; +#[derive(Default)] pub struct SavedSourceMap { - /// This is a pointer to the map located on the VirtualMachine struct - pub map: *mut HashTable, - pub(crate) mutex: Mutex, -} - -impl Default for SavedSourceMap { - fn default() -> Self { - Self { - map: ptr::null_mut(), - mutex: Mutex::default(), - } - } + /// Only accessed between [`Self::lock`] and [`Self::unlock`]. + map: HashTable, + mutex: Mutex, } impl SavedSourceMap { - // In-place init — `this` is a pre-allocated field on VirtualMachine; `map` is a sibling field backref. - - /// Mutable access to the sibling `HashTable` on `VirtualMachine`. - /// - /// # Safety invariant - /// `self.map` is set in [`Self::init`] to a non-null pointer at a sibling - /// field on `VirtualMachine` and is never reassigned; the pointee outlives - /// `self`.

Runtime ESM that Bun hands to JSC with a prebuilt module record (`bun test --isolate` / `--parallel`, `bun build --compile` output) uses that source type, and `gatherDebuggerParseDataForSource` returned false for it, so `Debugger.setBreakpoint` replied "Could not resolve breakpoint" and `Debugger.setBreakpointByUrl` returned no locations for those files. - oven-sh/WebKit#406: exception checks on the inspector's pause / `evaluateOnCallFrame` / `Runtime.evaluate` paths (`JSJavaScriptCallFrame`, `JSInjectedScriptHost`, `jsToInspectorValue`). Under `validateExceptionChecks` (the ASAN lane) a paused inspectee used to abort at `JSJavaScriptCallFrame::scopeChain`, which is why `inspector.test.ts` stripped the flag for its children and `inspect.test.ts` sat in `no-validate-exceptions.txt`. Both workarounds are removed here; all of `test/cli/inspect/*` and `test/js/node/inspector/inspector.test.ts` pass locally with the flag forced on for every child. - oven-sh/WebKit#403 also landed in between: `ALWAYS_INLINE` is `__always_inline__` again in release builds, so `NodeUtilTypesModule.cpp` now includes `ObjectPrototypeInlines.h` for `objectPrototypeToString` (the only out-of-line use that relied on the old stopgap; release links locally against the new tarball). `test/cli/inspect/debugger-buntranspiledmodule.test.ts` (from #35754, updated for the `scriptType` param the Aug 2 upgrade introduced) drives `bun test --isolate` under `--inspect-wait` and asserts both breakpoint calls resolve; it fails on `447082ab` and passes here. #35605 makes every `bun run` module take the `BunTranspiledModule` path; splitting the bump out so it can land first.

On macOS `KEventWaker::wake` took `&mut self` while `LinuxWaker::wake` and `WindowsWaker::wake` take `&self`. The two cross-thread callers (`BundleThread::enqueue` and `IoRequestLoop::schedule`) call `wake` through a raw pointer while the owning thread is parked in `wait(&self)` on the same waker, so on macOS that autoref materialised a `&mut KEventWaker` aliasing a live `&KEventWaker` on another thread. Nothing is miscompiled today because `wake` only reads the Copy `mach_port` and hands it to `mach_msg`, but it is aliasing UB under Stacked Borrows and a trap for whoever next adds state to `wake` trusting the `&mut`. `wake` now takes `&self` (body unchanged), the IO-loop call site uses `addr_of!` instead of `addr_of_mut!`, and the two SAFETY comments that claimed "`wake` is `&self` on all platforms" and cited a `has_pending_wake` AtomicBool that no longer exists now describe what is actually there. The follow-up commit fixes the same shape one line up in `IoRequestLoop::schedule`: `(*LOOP.get_unchecked()).as_mut_ptr()` goes through `MaybeUninit::as_mut_ptr(&mut self)`, so it autoref'd a `&mut MaybeUninit` on the scheduling thread while the IO thread holds `&IoRequestLoop` across `tick()`, on every platform, directly under a SAFETY comment saying that does not happen. The raw pointer is now cast instead (`MaybeUninit` is `repr(transparent)`; `bundler/ThreadPool.rs` and `io/source.rs` already access their `MaybeUninit` statics this way), so the only references formed on that path are the `&pending` / `&waker` autorefs. It also describes the Windows waker correctly in the `BundleThread::enqueue` comment (it hands the `WindowsLoop` pointer to `uv_async_send`, not a Copy fd). `HTTPThread::schedule` / `shutdown_for_exit` have the same `as_mut_ptr()` autoref, but the HTTP thread holds a `&'static mut HttpThread` across `process_events`, so that one needs a separate change and is left alone here. ### How did you verify your code works? `cargo check -p bun_io -p bun_bundler` on macOS. Built `bun-debug` and ran 50 concurrent plus 20 sequential `Bun.build` calls (concurrent `enqueue`/`wake` against the bundle thread's `wait`) and `bun build` from the CLI; all succeed. Linux/Windows are untouched apart from the shared `addr_of!` call site, which type-checks the same way there since their `wake` was already `&self`. Follow-up commit: `cargo check -p bun_io -p bun_bundler` for the linux, darwin, windows-msvc and freebsd targets, clippy and fmt clean. Linux debug build: `test/bundler/bun-build-api.test.ts` plus 50 concurrent and 20 sequential `Bun.build` calls; for the `schedule()` path, piping 4 MB into `Bun.stdin.text()` with `BUN_DEBUG_WriteFile=1` shows `ReadFile.waitForReadable` (which calls `schedule`) firing ~300 times with the full length read back, and `test/js/bun/io/bun-write.test.js`, `test/js/bun/util/bun-stdin-slice.test.ts` and the stdin regression tests (07500, 27849, 29787) pass. The generated code is unchanged (only the reference types formed on the scheduling side differ), so there is no runtime test for this; instead `test/internal/source-lints/thread-cell-unchecked-as-mut-ptr.test.ts` bans the `(*cell.get_unchecked()).as_mut_ptr()` shape tree-wide. It fails on the base tree (reports `src/io/lib.rs:929`) and passes with this PR; the two `HTTPThread` sites are ratcheted in its allowlist until that change lands. --- **[review]** gate passed · iteration 2 · 3 files touched

The slots were typed as non-owning pointers (`Option>`, `*mut StaticRoute`, `*mut HTMLBundleRoute`), so each release was spelled out by hand: in `invalidate_client_bundle`, in `Assets::replace_path` / `unref_by_index` / `Drop for Assets`, in a `scopeguard::defer!` in `on_js_request`, and in a loop at the end of `Drop for DevServer`. Two sites in `finalize_bundle` took the `cached_response` handle out of its slot without releasing it (the HTML chunk loop, where `invalidate_client_bundle` then found the slot already empty, and the `had_adjusted_edges` loop, whose `let _ = blob;` released nothing because `BackRef` is `Copy` and has no `Drop`), so the rendered page leaked on every rebuild of an HTML route that had been served since its last invalidation. ```rust // before (route_bundle.rs) pub(crate) html_bundle: *mut HTMLBundleRoute, pub(crate) cached_response: Option>, pub(crate) client_bundle: Option>, pub(crate) files: ArrayHashMap, // assets.rs // after pub(crate) struct StaticRouteRef(bun_ptr::BackRef); impl StaticRouteRef { pub(crate) fn init_from_any_blob(blob: AnyBlob, options: InitFromBytesOptions<'_>) -> Self; pub(crate) fn as_ptr(&self) -> *mut StaticRoute; // for StaticRoute::on* } impl Deref for StaticRouteRef { type Target = StaticRoute; .. } impl Drop for StaticRouteRef { .. CellRefCounted::deref_nn(self.0.into()) } pub(crate) html_bundle: bun_ptr::RefPtr, // released by Drop for Html pub(crate) cached_response: Option, pub(crate) client_bundle: Option, pub(crate) files: ArrayHashMap, ``` `StaticRouteRef` lives in `route_bundle.rs`; its only constructor wraps `StaticRoute::init_from_any_blob` and adopts the ref that constructor creates, so the one `unsafe` block (`BackRef::from_raw_mut` on the fresh allocation) is inside the type and `Deref` and `Drop` are safe code. The 5 creation sites (`on_js_request`, `on_html_request_with_bundle`, `on_js_request_with_bundle`, and both branches of `Assets::replace_path`) call it directly. `invalidate_client_bundle` and the two `finalize_bundle` sites become `take()` / `= None`; `Assets::replace_path` overwrites the slot, `unref_by_index` lets `swap_remove_at` drop the value, `Drop for Assets` and the loop in `Drop for DevServer` are deleted, and the `defer!` in `on_js_request` becomes the local's drop. `html_bundle` is created with `RefPtr::init_ref` where `RefCount::ref_` was called and released by a new `Drop for Html`; its 4 readers use `Deref` instead of raw dereferences, which also retires the two `#[allow(clippy::needless_borrow)]` attributes that existed for those expressions. `Assets::get` returns `Option<&StaticRouteRef>` (2 callers) and becomes `pub(crate)` to match the type. Overall this removes 15 `unsafe` blocks and adds 1. `Assets::replace_path` used `ArrayHashMap::get_or_put`, which requires `V: Default` because it appends a defaulted slot; the owning handle has no default, so the lookup now goes through the existing `entry()` API, and `OccupiedEntry` / `VacantEntry` in `bun_collections` gain `index()` (with a unit test) so the entry position is still available without a second lookup. ## Why Ownership of these refs is now stated by the slot types: a `StaticRouteRef` or a `RouteBundle` holding one cannot be dropped without releasing, and a copy that outlives the slot cannot be made, which is exactly the mistake the two leaking sites made; fixing those leaks is the only behavioural difference. `BackRef` is `repr(transparent)` over `NonNull`, so `Option` and the map value column stay 8 bytes, `RefPtr` is a `NonNull` in release builds, `Deref` and `as_ptr` compile to the field read the raw pointer was, the `Drop` bodies are the same `deref` calls the deleted code made, and `entry()` performs the same single hash and probe as `get_or_put`. The refs that `Drop for DevServer` released at the end of its body are now released when the `route_bundles` field is dropped a moment later; nothing in between touches them, and neither `StaticRoute`'s nor `Route`'s destructor reads `DevServer` (the asset routes were already released by `Assets`' field-order drop). Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

From aa9a59fb7f6ef1d4c0ffd89a3777bedf2aef4c2c Mon Sep 17 00:00:00 2001 From: robobun Date: Tue, 11 Aug 2026 17:27:15 -0700 Subject: [PATCH 271/304] usockets: follow the whole adopted-socket chain when re-deriving the live socket (#37661) ### What does this PR do? When `us_socket_adopt` has to grow a socket's ext it goes through `us_poll_resize`, which allocates a new `us_socket_t`, copies the old one over, and retires the old block: `is_closed = 1`, `flags.adopted = 1`, `prev = `, pushed onto `loop->data.closed_head` (context.c, `us_socket_adopt`). The dispatcher in `loop.c` is usually holding the old pointer while this happens (the adoption runs inside `on_open`, `on_writable` or `on_data`), so after each of those callbacks it re-derives the live socket from that bookkeeping. Until now every one of those sites followed exactly one link: ```c if (s && s->flags.adopted && s->prev) { s = s->prev; } ``` That is only right if the socket was relocated once per callback. Every relocation retires its source block the same way, so a callback that adopts twice before returning (`old -> mid -> new`, with `mid` also flagged and pointing at `new`) leaves one hop parked on `mid`, which is itself retired. The `is_closed` checks that follow then give up on the rest of the event for a socket that is still live: the readable half of a combined readable+writable event, the rest of the recv drain loop and the eof/error handling behind it (loop.c), the deferred-accept readable dispatch after `on_open`, and on Windows the paused-socket probe and `fin_deferred` bookkeeping in `poll_cb` (libuv.c). The kernel re-reports these level-triggered conditions on the next tick, so the result is a dropped event tail rather than a crash, but the bookkeeping is only correct because there happens to be a single link. The fix replaces the five copies of the one-hop `if` with one helper in `internal/internal.h`, `us_internal_socket_follow_adopted`, which walks to the end of the chain. `loop.c` uses it at the four dispatch sites, and the libuv.c `us_internal_poll_cb_adopted_socket` helper that `poll_cb` already funnels through now calls it too. Nothing else reads `flags.adopted`, so these are all the readers. Why walking the chain is sound: - Every block on the chain is still allocated while a dispatch holds it. Retired blocks sit on `closed_head` and are only freed by `us_internal_free_closed_sockets`, which runs in the outermost tick's `us_internal_loop_post`, never from inside a dispatch (see the `tick_depth` check in loop.c). For the same reason a retired block's memory cannot be handed out as a new socket within the tick. - The walk terminates on the live block. `us_poll_resize` copies the source before `us_socket_adopt` flags it, so the copy, and therefore the live tail, always has `adopted` clear. `adopted` is set in exactly one place and always together with `prev`, so every link the walk follows is a forwarding link. When `adopted` is clear, which is every socket today, the `while` evaluates its condition once, which is the same work the `if` did. The NULL tolerance of the old checks is kept because `on_writable` and `on_data` may return NULL. ### Reachability and testing This PR has no test because the code it changes cannot currently execute. No in-tree adopter grows its ext: `upgradeTLS`, the Postgres and MySQL TLS upgrades (`adopt_tls`) and the WebSocket client (`adopt_group`) pass equal pointer-sized old/new ext sizes, and the uWS server WebSocket upgrade shrinks (checked against this tree's headers: `sizeof(WebSocketData) + sizeof(void *)` is 168 vs `sizeof(HttpResponseData)` at 232), so `us_poll_resize` always takes its early return and `flags.adopted` is never set. The redirection itself dates from #25361; #37098 (open, same grow path) reaches the same conclusion and adds a fault-injection hook so that a single relocation can be exercised. A two-link chain additionally needs two adoptions inside one callback, which nothing JS-reachable does even with that hook. There is therefore no input on which the old and new code behave differently, and any test added here would pass with or without the change, so none is included. The change adds no state and touches no data structures. It also does not touch `context.c` or `epoll_kqueue.c`, so it is independent of #37098; if that lands first, its tests run the helper's one-link case for real. ### How did you verify your code works? - The debug (ASAN) build compiles, including the C++ translation units that include `internal.h` (`AsyncSocket.h`, `libuwsockets.cpp`, `bindings.cpp`). libuv.c is Windows-only and its change is a one-line body replacement behind the same signature; the Windows CI lanes compile it. - `bun bd test test/js/bun/net/socket.test.ts` and `test/js/bun/websocket/websocket-server.test.ts` cover the in-tree adopters (`upgradeTLS`, server WebSocket upgrade). The only failures are the ones this sandbox also produces with the released binary: `localhost` resolving to `::1` makes a handful of `Bun.connect` tests fail with ECONNREFUSED, one test needs public DNS, and the 300k-message `(benchmark)` case exceeds its 30s budget under ASAN. Everything else passes. --- packages/bun-usockets/src/eventing/libuv.c | 6 +----- packages/bun-usockets/src/internal/internal.h | 15 +++++++++++++++ packages/bun-usockets/src/loop.c | 16 ++++------------ 3 files changed, 20 insertions(+), 17 deletions(-) diff --git a/packages/bun-usockets/src/eventing/libuv.c b/packages/bun-usockets/src/eventing/libuv.c index e1eb0551b3ef..298be8254ee8 100644 --- a/packages/bun-usockets/src/eventing/libuv.c +++ b/packages/bun-usockets/src/eventing/libuv.c @@ -44,11 +44,7 @@ int us_internal_libuv_peer_reset_probe(LIBUS_SOCKET_DESCRIPTOR fd) { } static struct us_socket_t *us_internal_poll_cb_adopted_socket(struct us_poll_t *wp) { - struct us_socket_t *s = (struct us_socket_t *)wp; - if (s->flags.adopted && s->prev) { - s = s->prev; - } - return s; + return us_internal_socket_follow_adopted((struct us_socket_t *)wp); } static int us_internal_poll_cb_socket_is_probeable(struct us_poll_t *wp) { diff --git a/packages/bun-usockets/src/internal/internal.h b/packages/bun-usockets/src/internal/internal.h index 8444fa14b641..eca40c7d92c1 100644 --- a/packages/bun-usockets/src/internal/internal.h +++ b/packages/bun-usockets/src/internal/internal.h @@ -343,6 +343,21 @@ struct us_socket_t { _Static_assert(sizeof(struct us_socket_flags) == 1, "us_socket_flags grew"); #endif +/* us_socket_adopt relocates a socket whose ext grows and retires the old block + * (is_closed + adopted, prev -> replacement; freed by the outermost tick's + * us_internal_free_closed_sockets, so it is still readable mid-dispatch).

Its only implementor, `BlobReadChain` in src/runtime/image/Image.rs, used that receiver to reclaim the Box it lives in: ```rust fn on_read_bytes(&mut self, result: ReadBytesResult) { let boxed = unsafe { bun_core::heap::take(std::ptr::from_mut::(self)) }; boxed.on_read_bytes_impl(result); // Box freed here, while `&mut self` is still on the stack } ``` This is the `Bun.Image` source path for `Bun.file()` / `Bun.s3()` / zero-length in-memory Blobs. No crash is known; it is an aliasing-model violation (latent UB), found while converting `Blob::deinit` (#37672), which has the same shape. ### Why it is wrong A reference argument is protected for the whole call under both aliasing models, and deallocating protected memory is UB even if the reference is never used again. `bun_runtime` cannot run under Miri, so here is a reduction with exactly this shape (a trait method `on_read_bytes(&mut self)` that `Box::from_raw`s its receiver, dispatched as `H::on_read_bytes(unsafe { &mut *ctx }, ..)` like the sites in `read_bytes_to_handler`), next to the shape this PR switches to: ``` # Tree Borrows (the flags `bun run rust:miri` uses) test tests::by_ptr_receiver ... ok test tests::by_ref_receiver ... error: Undefined Behavior: deallocation through <144833> at alloc47733[0x0] is forbidden = help: the allocation of the accessed tag <144833> also contains the strongly protected tag <144822> = help: the strongly protected tag <144822> disallows deallocations 18 | let boxed = unsafe { Box::from_raw(std::ptr::from_mut::(self)) }; help: the strongly protected tag <144822> was created here, in the initial state Reserved 17 | fn on_read_bytes(&mut self, bytes: Vec) { # Stacked Borrows test tests::by_ref_receiver ... error: Undefined Behavior: deallocating while item [Unique for <131080>] is strongly protected test tests::by_ptr_receiver ... ok ``` ### Fix The trait method becomes `unsafe fn on_read_bytes(this: *mut Self, result)`, the shape `ReadFileCompletion::run(ctx: *mut Self, ..)` in blob/read_file.rs already uses for the same job: `read_bytes_to_handler` passes the `ctx` it was given straight through at its four delivery sites (file completion, file cancel, S3 callback, synchronous in-memory), and the Image impl does `heap::take(this)`. The only frame on the stack when the Box is freed now holds a raw pointer, which is what both models allow. No behaviour change; the pointer value delivered is the same one as before. The handoff also asked whether `BlobReadChain::start` leaks the chain when `read_bytes_to_handler` returns `Err`. It does not: the only `Err` source is the S3 branch, and `execute_simple_s3_request` only returns `Err` when the callback itself did, i.e. after it has already delivered to (and consumed) the handler; the file branch is infallible and the in-memory branch delivers before returning. That "exactly one delivery, whatever the return value" contract is what the ownership transfer relies on, so it is now written down on `read_bytes_to_handler` instead of being implicit. ### Tests - `test/internal/source-lints/self-receiver-reclaim.test.ts` pins the shape tree-wide (`heap::take` / `heap::destroy` / `Box::from_raw` of `self` or a pointer spelled from `self`). It fails on main with `src/runtime/image/Image.rs:1385: heap::take(std::ptr::from_mut::(self)` and passes with this change. `Blob::deinit` in src/jsc/webcore_types.rs is the one other instance; it is allowlisted with a ratchet and is being converted in #37672. That PR adds the same lint file with the allowlist the other way round, so whichever of the two lands second drops the remaining allowlist entry (the ratchet test says so when it happens); the two PRs do not otherwise touch the same lines. - `test/js/bun/image/image.test.ts`: new case for an S3-backed source (local `Bun.serve` endpoint, success and `NoSuchKey`) and a zero-length in-memory slice (synchronous delivery), the two deliveries the existing `Bun.file()` test does not reach. The S3 client applies an ambient `HTTP_PROXY` regardless of `NO_PROXY` (#32045), so the test blanks the proxy variables around the S3 calls. - `test/js/web/workers/worker-refused-completion.test.ts`: new row with an image read in flight when the worker goes away, so the cancel delivery (handler told `ECANCELED`, frees itself) runs under the debug/ASAN build.

It did that with `object->get()` on every own enumerable property, so every accessor on the exports object ran at import time. Those accessors are the builtins' lazy-loading mechanism, which means they only ever helped `require()` callers: - `node:fs`: `ReadStream`, `WriteStream`, `FileReadStream`, `FileWriteStream`, `Utf8Stream` each `require("internal/fs/streams")`, which loads the whole `node:stream` stack. - `node:tls`: `rootCertificates` parses the bundled CA store, `DEFAULT_CIPHERS` queries BoringSSL. - `node:http`: `globalAgent` instantiates the agent. `node:timers` / `node:stream`: `promises` load `timers/promises` and `stream/promises`. `node:assert`: `AssertionError` loads `internal/assert/assertion_error`. `node:repl`, `node:events`, `node:buffer`, `node:os` have a few more. #35541 is about to turn more of these into accessors (`fs.promises` among them), which this path would immediately defeat for the most common import style there is. ## Repro ```js // probe.mjs, run as `bun --expose-internals probe.mjs esm` vs `... require` const mode = process.argv[2]; const { createRequire } = await import("node:module"); let t = performance.now(); if (mode === "esm") await import("node:fs"); else createRequire(import.meta.url)("node:fs"); const fsMs = performance.now() - t; t = performance.now(); createRequire(import.meta.url)("internal/fs/streams"); console.log(mode, "node:fs", fsMs.toFixed(1), "ms; internal/fs/streams afterwards", (performance.now() - t).toFixed(1), "ms"); ``` bun 1.4.0 (release): `esm node:fs 13.3 ms; internal/fs/streams afterwards 0.2 ms` (already loaded) vs `require node:fs 7.8 ms; internal/fs/streams afterwards 5.0 ms`. On a debug build the difference is ~370ms per process, and `test/harness.ts` does `import fs from "node:fs"`, so every test file paid it. The directly observable form, which the tests use: the `node:fs` getters replace themselves with data properties when they run, so after `import fs from "node:fs"`, `Object.getOwnPropertyDescriptor(fs, "ReadStream")` had a `value` instead of a `get`. ## Fix An ES module binding cannot be made lazy from the embedder side: once the record exists, named imports read the exporting environment's slot directly (`ModuleVar`) and namespace reads go through `getValue()` in `JSModuleNamespaceObject`, so the slot has to hold the value before anything binds to it. The engine half is oven-sh/WebKit#408, merged as 7b763944f0ec. `WEBKIT_VERSION` moves from 09e477744721 (what main pins) to that sha; it is the only commit between the two: - `SyntheticModuleRecord::tryCreateWithExportNamesAndValues()` gets an overload taking a source object; an export whose value is the empty `JSValue` is declared but left in TDZ. - `materializeLazyExport()` fills such a slot from `source[name]` the first time something binds to it: `CyclicModuleRecord::initializeEnvironment` when an importer links a named import that resolves to it (directly or through `export *` / `export { x } from` chains), `JSModuleNamespaceObject::getOwnPropertySlotCommon` when a namespace read finds the slot empty (it then re-reads and installs the value the same way as before, so the namespace IC still applies), and `WebAssemblyModuleRecord::initializeImports`, which snapshots imported bindings directly (unreachable in bun today, reachable once #35587 lands). It is a no-op for a slot that already has a value, so `overrideExportValue` (what `mock.module` and `spyOn` use) keeps winning, `*namespace*` is skipped, a getter that re-enters keeps the first value that landed, and an exception from the getter propagates and leaves the slot for the next attempt. The write uses the same `symbolTablePutTouchWatchpointSet` the eager path used for its one write, so IC / DFG behaviour after materialization is identical to an eagerly built record; the baseline namespace IC already bails to the slow path on an empty slot and the DFG only folds loads that went through an installed IC. - `SyntheticSourceProvider::createWithLazyExports()` takes a generator that returns the source object, and `makeModule` passes it through. Records built any other way (JSON modules, `vm.SyntheticModule`, every existing `create()` caller) have no source object and take a pointer test on the new paths. The bun half is `generateInternalModuleSourceCode`: it now looks each property up with `getOwnPropertySlot`, snapshots data properties exactly as before, declares everything else (accessors) as a lazy export, and returns the exports object as the source. A builtin without accessors (most of them) produces a record identical to the old one. `require()` of a builtin never went through this function (`fetchCommonJSModule` returns the registry object), so it is unaffected. The engine change is inert without this opt-in: building the new WebKit with the old `ModuleLoader.cpp` still fails the new tests the same way the release does. ### Why this is the right behaviour Node builds the ESM facade of a builtin by reading the getters too, so the old behaviour was not wrong, just expensive, and there is no compat reason to keep it. The only observable difference is *when* an accessor export is sampled: at import before, at the point something first binds to it now. Data properties still snapshot at import. A namespace export or named import of an accessor is a snapshot either way (that is what `module.syncBuiltinESMExports()` exists for), and the later sample is never staler than the old one. Everything an importer can do with the export resolves to the same object `require()` would hand out, which is what the tests check for each binding path. `Object.keys(ns)`, `hasOwnProperty`, spread, and `console.log(ns)` still materialize what they touch, because `[[GetOwnProperty]]` has to produce the value; `in` ([[HasProperty]]) does not. Plugin `loader: "object"` modules and user CommonJS imported from ESM are deliberately not touched: those expose user objects whose getter timing is user-visible (#36677 is about that), whereas builtins' accessors are our own lazy-loading idiom. ## Tests `test/js/bun/resolve/builtin-esm-lazy-exports.test.ts`, next to the other module-system behaviour tests in that directory. Each case runs in its own process (a binding can only be materialized once) and checks both that importing left the `node:fs` accessors untouched and that the binding is the real class once used, for: default + named data import, named import of an accessor (exactly that one materializes), `import * as`, `import defer * as`, dynamic `import()` including `Object.keys` and that the export list is unchanged, `export *` and `export { x as y } from` re-exports (named import through the star and a read off the re-exporter's namespace, which exercises materializing on a record other than the namespace's own), accessors on `node:assert` (a function exports object), `node:timers` and `node:stream`, and `spyOn` / `mock.module` on an already imported builtin. 7 of the 8 cases fail on the current eager code (everything reports `value`); the `assert`/`timers`/`stream` identity case is a regression guard. With the fix, the probe above reports `internal/fs/streams` as not loaded after `import("node:fs")` (debug build: 338ms to load it afterwards in both modes, versus 10ms before because the import had already loaded it). Also run on the new build: `test/js/node/fs/fs.test.ts` (covers the existing `export { ReadStream, WriteStream } from "node:fs"` and `export * from "node:fs"` fixtures), the `test/js/bun/resolve` module tests, `test/js/bun/test/mock/mock-module*.test.ts`, `node-module-module.test.js`, `buffer-inspectmaxbytes.test.ts` (which pins that a named import of an accessor is a snapshot), and the events / os / timers / assert / tls-internals / node-http suites, all green apart from two failures that are identical on the released binary in this environment (`os.userInfo`, the http proxy test). --- **[decide:webkit]** gate passed · iteration 0 · 3 files touched

The runner's retry passes (node_modules is already populated, so the postinstall does not run again), so every build on those hosts carries this warning annotation and spends an extra download plus retry delay before running tests; a host that ever lost the retry would fail outright. ``` [2/3131] test/package.json - code 1: Error: ERROR: Failed to set up chrome-headless-shell v131.0.6778.87! Set "PUPPETEER_SKIP_DOWNLOAD"... [cause]: Error: The browser folder (/Users/administrator/.cache/puppeteer/chrome-headless-shell/mac_arm-131.0.6778.87) exists but the executable (.../chrome-headless-shell-mac-arm64/chrome-headless-shell) is missing error: postinstall script from "puppeteer" exited with 1 ``` ## Why `test/package.json` lists `@types/puppeteer@7.0.4`, a deprecated stub whose only content is a dependency on `puppeteer@*` (resolved to 23.10.1). With the isolated linker the stub has no `.d.ts` and `puppeteer` itself is not resolvable from test files, so `tsc` reports `Cannot find module 'puppeteer'` for `dev-server-puppeteer.ts` with or without it; it contributes nothing. It does make `puppeteer` (default trusted) run its postinstall in every CI job's `test/` install, downloading Chrome and chrome-headless-shell (~250 MB) into `~/.cache/puppeteer`. `bun install` runs that postinstall (`node install.mjs`) with the `node` in PATH, which on these agents is Node v26.3.0. puppeteer 23's `install.mjs` calls `downloadBrowsers()` without awaiting it, and under current Node the extract-zip/yauzl pipeline stalls on the first file that hits backpressure (the fd-slicer behavior `test/js/node/stream/node-stream.test.js` documents as a deliberate divergence), so the process exits 0 with only the first couple of entries extracted and `bun install` reports success. Both agents hold the identical leftovers: `chrome-headless-shell-mac-arm64/{ABOUT,LICENSE.headless_shell}` and a `Google Chrome for Testing.app` containing only the 186 KB launcher stub, all written within one second during the first fleet job ([build 92581](https://buildkite.com/bun/bun/builds/92581), which passed). Reproduced locally with Node 26.3.0 and an un-awaited `extract-zip` on a 3203-entry archive: 3002 entries written, exit 0. Every later job on the same host then hits the check above in `@puppeteer/browsers` on its first install attempt. #34372 found the same mechanism in the next-pages fixture last month and moved that browser install out of `bun install`; the top-level `test/` install still had it. It only became visible now because the tart agents discard the guest (and its cache) after each job, while the bare-metal agents brought back in #37633 keep `~/.cache` between jobs. ## Fix - Remove `@types/puppeteer` from `test/package.json`. The regenerated `test/bun.lock` drops the 48 packages only puppeteer pulled in and introduces no new resolutions (the `jsbn` rehoist in the diff is what `bun install` already rewrites on main today). - `spawnBunInstall` in `scripts/runner.node.mjs` (the runner's own root/test/vendor dependency setup) sets `PUPPETEER_SKIP_DOWNLOAD=1`, so a puppeteer that comes back transitively cannot write into the shared cache either. The env is only applied to those install processes; tests that need a browser keep installing one into a per-run cache through `getPuppeteerInstallEnv()`, and `dev-server.test.ts` already passes `PUPPETEER_SKIP_DOWNLOAD=1` to its own `bun install` for the same reason. The two affected hosts still need their `~/.cache/puppeteer` removed once; branches that predate this change keep hitting the first-attempt failure on them until they rebase. No CI job on `main` writes there after this. ## Verification - `cd test && bun install --lockfile-only` produces exactly the committed lockfile; the set of resolved `name@version` entries after is a strict subset of before. - `test/package-json-lint.test.ts` passes; `node --check scripts/runner.node.mjs`; prettier clean. - `grep` for `puppeteer` under `test/` outside `next-pages` (which has its own `package.json` and browser install) finds no consumer of the top-level package. --- **no test proof** · iteration 0 · docs-only change; test-proof not applicable --- scripts/runner.node.mjs | 10 ++- test/bun.lock | 151 +--------------------------------------- test/package.json | 3 +- 3 files changed, 13 insertions(+), 151 deletions(-) diff --git a/scripts/runner.node.mjs b/scripts/runner.node.mjs index b6e5bddf8b2e..93fcd25793ce 100755 --- a/scripts/runner.node.mjs +++ b/scripts/runner.node.mjs @@ -2209,7 +2209,15 @@ async function spawnBunInstall(execPath, options) { args: ["install"], timeout: testTimeout, ...options, - env: { ...options.env, ...(cacheDir && { BUN_INSTALL_CACHE_DIR: cacheDir }) }, + env: { + // A puppeteer postinstall reached through these installs would download + // Chrome into the agent's shared ~/.cache; a half-extracted download left + // there on a persistent agent fails every later job's install.

This makes the write path consistent with them: - A write issued while `ssl_in_use` is set, i.e. from a callback that `SSL_read` / `SSL_do_handshake` on this same socket is currently running, is parked instead of calling `SSL_write`: it returns 0 and sets `ssl_write_wants_read`, exactly what a write issued before the handshake already gets on the `WANT_READ` path. The caller buffers, and the existing `ssl_retry_parked_write` dispatches writable once the handshake completes. - `SSL_write` itself now runs with `ssl_in_use` set and honors `ssl_pending_detach` in its epilogue, the same shape as the other two drivers (`SSL_write` drives the handshake while it is pending, so it is a driver too). ### Observable before / after The first point is reachable today. The server-side ALPN and SNI selection callbacks run from inside the `SSL_read` that is processing the ClientHello, and both hand the accepted socket to JS (`Bun.listen`'s `alpnCallback` / `serverName` hooks, which `node:tls`'s `ALPNCallback` / `SNICallback` are built on). A `socket.write()` there re-entered BoringSSL on the SSL it was still working on and the handshake failed: ```ts const server = tls.createServer({ key, cert, ALPNCallback({ protocols }) { conn.write("hi"); return protocols[0]; } }); server.on("connection", s => (conn = s)); // client: error:10000438:SSL routines:OPENSSL_internal:TLSV1_ALERT_INTERNAL_ERROR // server: tlsClientError error:100000c2:SSL routines:OPENSSL_internal:PROTOCOL_IS_SHUTDOWN ``` With this change the handshake completes and the bytes are delivered right after it, ahead of anything written from `secureConnection`. At the `Bun.listen` level the write reports 0 and `drain` fires once the handshake is done, which is the contract a pre-handshake write already has. (`socket.end("bye")` from inside the callback goes through the same path and now works as well.) The second point has no reachable trigger at the moment: `us_internal_ssl_write` zeroes the read-input window before calling `SSL_write`, so the ClientHello-driven callbacks cannot fire from inside it, the session and keylog callbacks are parked in ex_data and flushed after the SSL call returns, and `us_socket_raw_write` (what the BIO calls) never closes the socket. It is included so the write driver keeps the same invariants as the other two if that ever changes; if the deferred close did fire, the epilogue resets the batching state (so leftover records cannot leak into the next socket's batch), runs the close, and reports 0 like any write to a socket that is going away. `us_internal_ssl_shutdown` is intentionally left alone. It is reachable from the same callbacks (`socket.shutdown()` from inside the ALPN/SNI selection), but BoringSSL's `SSL_shutdown` returns 1 without touching any state while the handshake is in progress (`ssl_lib.cc`, "If we are in the middle of a handshake, silently succeed"), so the only effect is the TCP FIN and the connection the caller asked to shut down goes away; verified under the ASAN build from both callbacks. There is nothing to defer there, unlike a write, which has bytes to deliver after the handshake. ### Why this is the right place The guard has to live in `us_internal_ssl_write`: it is the only function that knows whether a BoringSSL call on this `SSL*` is on the stack, and every caller (`Bun.listen` sockets, `node:tls`, uWS) already treats 0 as "buffer and wait for writable", so parking needs no changes above it. Buffering in usockets or gating on the JS side would add a second buffer for a case the existing parked-write machinery already handles. It keys on `ssl_in_use` rather than on the handshake state because the two are different conditions: before the handshake completes, a write issued from outside any BoringSSL call is still meant to reach `SSL_write` (the https client flushes its headers on connect and that write drives the handshake; the tail of this function reports the handshake failure for it, #33390), so only a write issued while a BoringSSL call is actually on the stack is parked. ### Tests - `test/js/node/tls/node-tls-server.test.ts`: `write()` from inside `ALPNCallback` and from inside `SNICallback`; asserts the client receives the callback's bytes followed by the `secureConnection` bytes, the ALPN selection still applies, and no `tlsClientError` fires. Fails on main with the errors quoted above. - `test/js/bun/net/socket.test.ts`: the same through `Bun.listen`'s `alpnCallback` and `serverName` hooks, asserting the exact sequence `write:0` -> `handshake:true` -> `drain` -> `close` and that the data written from `drain` arrives. On main the sequence is `write:0` -> `handshake:false` -> `close`. Both pass 15/15 reruns with the debug (ASAN) build. Also ran `test/js/node/tls/`, `test/js/bun/net/socket.test.ts`, `tcp-server.test.ts`, `test/js/web/fetch/fetch.tls.test.ts`, `test/js/bun/http/bun-serve-ssl.test.ts` and `test/js/node/http2/node-http2.test.js` locally; the only failures are unrelated to this change (plain-TCP `localhost` listen/connect family mismatch in this container, reported separately, and a few subprocess-spawning tests that sit right at the 5s default timeout under the debug build here and pass with a longer timeout). --- packages/bun-usockets/src/crypto/openssl.c | 18 +++++ test/js/bun/net/socket.test.ts | 92 ++++++++++++++++++++++ test/js/node/tls/node-tls-server.test.ts | 66 ++++++++++++++++ 3 files changed, 176 insertions(+) diff --git a/packages/bun-usockets/src/crypto/openssl.c b/packages/bun-usockets/src/crypto/openssl.c index 91e7d3f78727..44ca0e9e9b94 100644 --- a/packages/bun-usockets/src/crypto/openssl.c +++ b/packages/bun-usockets/src/crypto/openssl.c @@ -2478,6 +2478,13 @@ int us_internal_ssl_write(struct us_socket_t *s, const char *data, int length) { return 0; } + /* Called from inside SSL_read/SSL_do_handshake on this socket (an ALPN/SNI + * callback writing): wait for the handshake, same as WANT_READ below. */ + if (s->ssl_in_use) { + s->ssl_write_wants_read = 1; + return 0; + } + struct loop_ssl_data *loop_ssl_data = (struct loop_ssl_data *)s->group->loop->data.ssl_data; /* Earlier batched records of ours must reach the wire before anything new: @@ -2506,7 +2513,18 @@ int us_internal_ssl_write(struct us_socket_t *s, const char *data, int length) { while (total < length) { int chunk = length - total; if (chunk > 16384) chunk = 16384; + /* Same deferred-close protocol as the SSL_do_handshake/SSL_read drivers. */ + s->ssl_in_use = 1; last_ssl_written = SSL_write(s_ssl(s), data + total, chunk); + s->ssl_in_use = 0; + if (s->ssl_pending_detach) { + /* Closed from inside the call: drop this write's records and close now. */ + loop_ssl_data->ssl_write_batching = 0; + loop_ssl_data->ssl_write_batch_len = 0; + s->ssl_pending_detach = 0; + us_socket_close(s, s->ssl_pending_close_code, NULL); + return 0; + } if (last_ssl_written <= 0) break; total += last_ssl_written; /* A batching allocation failure marks the socket fatal from inside the BIO; diff --git a/test/js/bun/net/socket.test.ts b/test/js/bun/net/socket.test.ts index a290fa66e076..58b7c760ff81 100644 --- a/test/js/bun/net/socket.test.ts +++ b/test/js/bun/net/socket.test.ts @@ -1448,6 +1448,98 @@ it("TLS mid-read boundary dispatch: writing to another TLS socket from data() do } }, 60_000); +describe.concurrent("TLS server: write() to the accepted socket from inside its own selection callback", () => { + // alpnCallback / serverName are the listener hooks node:tls's ALPNCallback / + // SNICallback go through.

From 8c7ed929cd0a6302e4c4c767946015cb876c1d45 Mon Sep 17 00:00:00 2001 From: robobun Date: Tue, 11 Aug 2026 19:43:57 -0700 Subject: [PATCH 278/304] streams: deliver a direct stream's post-flush bytes to pipeTo/tee/for-await read requests (#37692) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ### Repro ```js const mk = () => new ReadableStream({ type: "direct", pull(c) { c.write("hello"); c.flush(); c.write("world"); c.end(); }, // same with c.close() }); let acc = ""; await mk().pipeTo(new WritableStream({ write(ch) { acc += new TextDecoder().decode(ch); } })); console.log(acc); // "hello" (expected "helloworld") console.log(await new Response(mk().tee()[0]).text()); // "hello" console.log(await new Response(mk().pipeThrough(new TransformStream())).text()); // "hello" console.log(await new Response(mk()).text()); // "helloworld" ``` On 1.4.0 and current main, `pipeTo`, `pipeThrough`, `tee()`, `for await` and `Response.textStream()` all deliver only the bytes flushed before the mid-pull `flush()`; a plain reader and `text()` get everything. Two `flush()` calls in one sync `pull()` lose the second chunk the same way, and a `pull()` that throws synchronously additionally reports a stray `unhandledRejection` next to the consumer's own rejection. ### Cause Those consumers read a direct stream through read requests queued in the reader's `[[readRequests]]`, but `JSDirectStreamController::onPull` created a head-of-line promise (`m_pendingRead`) for every read, and `readableStreamDefaultReaderRead` dropped it again once `onPull` returned. The mid-pull `flush()` fulfils the queued request immediately, so when `onPull` replays the `end()`/`close()` (or second `flush()`) that the pull deferred, `headOfLinePromiseIsActiveConsumer` sees an empty request queue and hands the remaining bytes to the promise nobody holds. The sync-throw path rejected that same unobserved promise. ### Fix `onPull` takes a `readRequestQueued` flag. For a read request it registers no promise, so deferred close/flush deliveries reach the queued request, or arm the final chunk / stay in the sink for the consumer's next read, and a throwing pull only errors the stream. With no dropped promises left, `headOfLinePromiseIsActiveConsumer` and the post-pull `m_pendingRead` cleanup are removed, and `onFlush` only promotes a promise-kind request to head-of-line. The exception check after `callDirectPull` now runs before `handleError`, which the throwing-pull paths needed to pass `BUN_JSC_validateExceptionChecks` (the new test spawns one and inherits it on the ASAN lane). Related, not overlapping: #37687 fixes bytes flushed while nothing was waiting staying in the sink; the two PRs touch neighbouring lines of `onPull`. ### Verification New tests in `test/js/web/streams/streams.test.js` (reader, `pipeTo`, `pipeThrough`, `tee`, `for await`, `textStream()` with `end()` and `close()`, the double-flush case, and the throwing-pull subprocess): 12 of 14 fail on the unfixed build (`"hello"` / `"a"` received, `unhandled: 3`), all pass with the fix. `streams.test.js` passes in full under `BUN_JSC_validateExceptionChecks=1`; the other direct-stream suites (`body-stream`, `body-async-iterator`, `sync-pull-fast-path`, `AsyncLocalStorage`, `html-rewriter`, `node-stream`) are unchanged. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Repro (a local CONNECT proxy with a TLS listener, an https origin, both using the test certificate): ```ts for (let i = 0; i < 3; i++) { const res = await fetch(origin, { proxy: "https://127.0.0.1:" + proxyPort, tls: { ca } }); await res.text(); } // proxy saw 3 CONNECTs; with an http:// proxy, or with tls: { rejectUnauthorized: false }, it sees 1 ``` Cause: `HTTPThread::connect` opens the socket to an https proxy inside the per-config custom `HTTPContext` when the request's `tls` needs one, and the next request with the same config only searches that context's keep-alive pool. The tunnel's data path did not follow that. `ProxyTunnel::on_data` (the `ProxyHeaders` arm) and `progress_update_for_proxy_socket` always passed `http_thread().https_context` / `http_context` as the `ctx` that `send_progress_update_without_stage_check` hands to `release_socket`, so a finished tunnel was parked in the default context's pool. From there it was never matched again (the custom-config request looks in the other pool; a default-config request never matches an entry keyed with the custom `ssl_config`), so besides the lost reuse each such request left a dead entry in the default pool's 64 slots until the 5 minute idle timeout, and a socket belonging to the custom context's socket group was bookkept by a different context. Fix: these four sites now ask the client for its context (`get_ssl_ctx`), which is what every other release site in the client already does (`on_close`, `check_server_identity`, the streaming-body and preconnect paths, and the outer socket's `on_data` dispatch). For a plaintext (`http://`) proxy or a request without a custom context `get_ssl_ctx` returns the same default context as before, so those paths are unchanged. Pooling a tunnel inside a custom context needs nothing else: `PooledSocket::release_parked_refs` and `HTTPContext::drop` already handle a parked tunnel, and the pool lookup in `HTTPContext::connect` is the same code that already matches tunnels in the default contexts. Why this is the right place: `ctx` exists precisely so the release goes into the pool of the context that owns the socket; the tunnel callbacks were the only place in the client that computed it from the global instead of from the client. The custom-context connect path was added later than the tunnel code, and these sites were not updated with it. #37706 touches the same four lines (it routes them through a `default_context_ptr` helper and keeps the default-context behaviour). Whichever lands second has a trivial conflict: the ProxyTunnel sites should end up calling `get_ssl_ctx`, and `get_ssl_ctx` itself is where that helper belongs. ### How did you verify your code works? `test/js/bun/http/proxy-stress-concurrent.test.ts`: - New `tunnel reuse` matrix: http/https proxy x custom (`ca`) / default (`rejectUnauthorized`) context x three response shapes, 3 sequential requests each, asserting exactly one CONNECT at the proxy and one accepted connection at the origin. The shapes cover both changed sites: a content-length response and a 204 are released from the `ProxyHeaders` arm (`handle_on_data_headers`), and the chunked response only gets its body after `fetch()` resolved, so it is released from `progress_update_for_proxy_socket` (confirmed with the `http_proxy_tunnel` / `fetch` debug logs: `onData proxy_headers` -> `release socket` for the first two, `onData body_chunk` -> `release socket` for the third). The https-proxy + custom rows fail on the unfixed build with `{ connects: 3, originConnections: 3 }`; the http-proxy and default-context rows pass before and after. - The existing https-proxy assertions in `tunnel reuse`, `many origins`, `reject_unauthorized pool gate`, and `interleaved proxy/direct` (proxy-stress-adversarial.test.ts) had been loosened to ranges because of this behaviour (their `laxTls` carries a `ca`); they now assert the exact counts the http-proxy rows already asserted. On the unfixed build they fail with 5/3/24/3/3 CONNECTs respectively. Locally, `bun bd test` passes for proxy-stress-concurrent, proxy-stress-adversarial, proxy-stress-{protocol,errors,headers,matrix,lifecycle}, proxy.test.ts and fetch-keepalive.test.ts. (proxy.test.js's two Proxy-Authorization tests fail in my container both with and without this change because the container sets `NO_PROXY=localhost`, which fetch honours even for an explicit `proxy` option; unrelated.) --- src/http/ProxyTunnel.rs | 20 ++- .../bun/http/proxy-stress-adversarial.test.ts | 15 +- .../bun/http/proxy-stress-concurrent.test.ts | 164 +++++++++++++----- 3 files changed, 142 insertions(+), 57 deletions(-) diff --git a/src/http/ProxyTunnel.rs b/src/http/ProxyTunnel.rs index 44d6899a90cc..118268e64cef 100644 --- a/src/http/ProxyTunnel.rs +++ b/src/http/ProxyTunnel.rs @@ -320,13 +320,17 @@ fn on_data(ctx: *mut HTTPClient, decoded_data: &[u8]) { } HTTPStage::ProxyHeaders => { scoped_log!(http_proxy_tunnel, "ProxyTunnel onData proxy_headers"); + // `hctx` is the pool the finished tunnel is released into.

The `"bun"` module is not one of those: it is a native module (`generateNativeModule_BunObject` in `src/jsc/bindings/BunObject.cpp`), and its generator still built the record eagerly: - `object->reifyAllStaticProperties()` runs every `PropertyCallback` in `bunObjectTable` (about 60 of them: `$`, `SQL`/`sql`/`postgres`, `S3Client`/`s3`, `RedisClient`/`redis`, `Glob`, `TOML`, `WebView`, `secrets`, `stdin`/`stdout`/`stderr`, ...) and stores each result on the object, so that line alone constructs every lazy `Bun.*` property. - `exportBunObject` then called `get()` on each of them to fill the export values. Note that the most common forms never reach this code: the transpiler rewrites a literal `import { write } from "bun"`, `import * as b from "bun"`, `import("bun")` and `require("bun")` into reads of `globalThis.Bun` (`src/js_printer/lib.rs`, `ImportRecordTag::Bun`), which is why `import { write } from "bun"` only ever constructed `write`. The generator runs for `export * from "bun"` / `export { x } from "bun"` and for `import()` with a non-literal specifier, and every one of those constructed all 115 static properties. ## Repro ```js // reexport.mjs export * from "bun"; // entry.mjs import { describe } from "bun:jsc"; import { write } from "./reexport.mjs"; // describe() dumps the Structure, i.e. the static-table entries that have been constructed so far. console.log(describe(Bun).match(/\{[^}]*\}/)[0].split(",").length); ``` Before: 116 entries (`Symbol.toStringTag` plus all 115). After: 2 (`Symbol.toStringTag` and `write`). A non-literal `import(specifier)` of `"bun"` behaves the same way. A second consequence of the eager path: a property callback that throws fails the whole module. `Bun.redis` builds the default client from `REDIS_URL` and throws on an invalid URL, so with `REDIS_URL='http://[::1'` the entry above died at load with `TypeError: Invalid URL format` even though it only wanted `write`. (The `DECLARE_TOP_EXCEPTION_SCOPE` in `exportBunObject` that turned getter errors into `undefined` never got to run for these, because `reifyAllStaticProperties()` propagated first.) ## Fix `generateNativeModule_BunObject` now has the `LazySyntheticSourceGenerator` signature from #37525. It lists the object's own property names (`getOwnNonIndexPropertyNames` includes the static table entries that have not been reified, so dropping `reifyAllStaticProperties()` leaves the export list unchanged, `DontEnum` entries excluded as before), provides `default` = the Bun object, appends an empty `JSValue` for every other export, and returns the Bun object as the source. JSC's `materializeLazyExport` then reads `Bun[name]` the first time something binds to that export: when an importer links a named import of it (directly or through `export *` / `export { x as y } from`), or when it is read off a namespace object. Reading it reifies exactly that one property on the Bun object, the same thing a direct `Bun[name]` access does, so the binding is identical to the property (`main`, the one `CustomAccessor`, is read through its getter like before). Plumbing: the native module list in `NativeModuleList.h` gets a separate `BUN_FOREACH_LAZY_ESM_NATIVE_MODULE` group for generators with this signature (the codegen scanner numbers modules by their order in the file, and `bun` was already last, so the ids do not move); `_NativeModule.h` forward-declares that group with the new return type; `ModuleLoader.cpp` dispatches it through `SyntheticSourceProvider::createWithLazyExports`; and `generateNativeModule` in `InternalModuleRegistry.cpp` (the generated `createInternalModuleById` case, which only needs the default export) becomes a template so it accepts both signatures. ### Behaviour differences - When a `Bun.*` value is sampled: at first binding rather than at module load. The affected values are constructed on first read and then fixed, so the same object is handed out either way; for `main` (a live getter) a re-export now samples the value when it is first bound rather than when the module loads, which is the same behaviour #37525 gave the builtins' accessors. - A throwing callback now throws from whatever binds to that export (the import that links it, or the namespace read, including `Object.keys(ns)` / `console.log(ns)` since those read every export), and the other exports keep working. Previously it failed the module. Of the current callbacks, `Bun.redis` throws on an invalid `REDIS_URL` / `VALKEY_URL`, `Bun.embeddedFiles` can throw on OOM, and `Bun.$`, `Bun.sql`, `Bun.postgres`, `Bun.SQL` would throw if their builtin failed to load; `Bun.s3` reports its error as unhandled and yields `undefined` instead. The error surfacing on the `redis` binding is the same error a direct `Bun.redis` read produces, which the new test pins. - `mock.module("bun", ...)` on an already loaded record writes into the binding with `overrideExportValue`; `materializeLazyExport` is a no-op for a slot that has a value, so the mock wins and the real property is never constructed. - No bulk reification means nothing here runs callbacks back to back without exception checks, which is what #33150 was fixing in the eager path; this supersedes it. Checked with `BUN_JSC_validateExceptionChecks=1` on the re-export, the non-literal `import()`, the throwing `redis` case, and a full `Object.keys(ns)` materialization. ## Tests Added to `test/js/bun/resolve/builtin-esm-lazy-exports.test.ts` (the file from #37525), each in its own process. The readout is `bun:jsc`'s `describe(Bun)`, filtered to a sample of the lazy properties plus `write`; `Object.getOwnPropertyDescriptor` cannot be used because it reifies the property it is asked about. - `export *` / `export { x as y }` / `export { default as ... }` re-exports: linking `import { write }` constructs only `write`; `in` constructs nothing; reading the renamed export constructs `Glob`; reading through the star constructs `SQL`; each is identical to the `Bun.*` value and stable across reads; `default` is the Bun object. - Non-literal `import()`: nothing constructed on import; `Reflect.ownKeys` of the namespace equals `Object.keys(Bun)` plus `default` and constructs nothing; reading `TOML` constructs only `TOML`; every export is `===` the corresponding `Bun` property (which constructs everything). The specifier is imported from the helper module because a `const` holding it can get inlined into a literal `import("bun")` in some files. - `REDIS_URL` set to an invalid URL: the module still loads, `reexported.redis` throws the same error as `Bun.redis`, other exports work. - `mock.module("bun", () => ({ SQL: "mocked" }))` in a `bun test` child after the re-export was imported: the namespace sees the mock, `SQL` is never constructed, `Bun.SQL` is intact. All four fail on the merge base (everything shows up as constructed after import; the `REDIS_URL` case fails at load), and the eight existing cases in the file pass on both. Also run on this build: `test/js/bun/util/BunObject.test.ts` (which `console.log`s a non-literal `import()` namespace of `"bun"` and compares every property), `test/js/bun/resolve/`, `test/js/bun/test/mock/`, `test/js/node/stubs.test.js`, `node-module-module.test.js`, and `test-process-get-builtin.mjs`; all green apart from `load-same-js-file-a-lot.test.ts`, which times out identically on the unmodified build in this environment. ## Startup Wall time of `bun file.mjs`, min of 10 runs after a warm-up, debug (ASAN) builds of the merge base and of this branch on the same machine: | file | before | after | | --- | ---: | ---: | | empty module | 273 ms | 264 ms | | `import { write } from "bun"; write.length` | 277 ms | 251 ms | | same, but `write` comes from a module doing `export * from "bun"` | 555 ms | 279 ms | The literal form is rewritten by the transpiler and was already at the floor; the re-export form loses the roughly 280 ms (debug build) it spent constructing the object.

Checked inside a running guest on `darwin-arm64-focaccia`: `/opt/rust/settings.toml` has `default_toolchain = "stable-aarch64-apple-darwin"`, `cargo --version` with job.sh's environment fails with the message above, and the same command with `RUSTUP_HOME=/opt/rust CARGO_HOME=/opt/rust` prints `cargo 1.97.1`. The bare agents are unaffected because `scripts/agent.mjs` runs jobs with `sh -elc`, which sources the profile; that is why the `darwin 26 aarch64` lane passes. ### Fix Export `RUSTUP_HOME` and `CARGO_HOME` in `job.sh` next to the `PATH` line that already hardcodes `/opt/rust/bin`. The test itself is left alone: it fails loudly on purpose (#33970), and that is what surfaced this. ### Rollout The hosts run the copy of `job.sh` installed in `/usr/local/share/darwin-ci` at provision time (`command.ts` pushes it into the guest per job), so this PR's own darwin 14 lane will still show the failure. The four tart hosts need the updated file copied into place (no agent restart needed; the next job picks it up), or a re-run of `main.ts provision`. cc @alii --- **no test proof** · iteration 0 · build/CI scripts only; test-proof not applicable --- scripts/darwin-ci/guest/job.sh | 3 +++ 1 file changed, 3 insertions(+) diff --git a/scripts/darwin-ci/guest/job.sh b/scripts/darwin-ci/guest/job.sh index 051fb3d824ac..3545ac487f10 100755 --- a/scripts/darwin-ci/guest/job.sh +++ b/scripts/darwin-ci/guest/job.sh @@ -2,6 +2,9 @@ # Runs inside the per-job guest.

With the exact release `cxxflags` from `build/release/build.ninja`: ``` $ clang++ -### -c x.cpp # -O3 ... -g1 -glldb -debug-info-kind=standalone $ clang++ -### -debug-info-kind=line-tables-only ``` So every release TU, vendored deps included, has been emitting full standalone DWARF (the CMake build had the same order, so this is not new). This PR moves the `-glldb` entry ahead of the level entries; debug builds keep `-g3` (same kind as before, only the command line order changes, so the next `bun bd` after pulling recompiles the C++ once), release builds get the line tables the entry has always asked for. Windows (`/Z7`) is untouched. ### Measurements Fresh C++-only builds (`ci-cpp-only` mode: deps, PCH, bun's C++, archive; no cargo) on a shared 12-core box with ccache disabled, slot-time summed from `.ninja_log`. The box is noisy (its load average drifted from ~30 to ~50 during these runs), so the ThinLTO configuration was built four times before and three times after, interleaved; the vendor objects, which this change barely affects, show the noise floor: | release + ThinLTO (what CI's build-cpp compiles) | before (4 runs) | after (3 runs) | |---|---|---| | bun's own C++ slot-time | 1472 / 1567 / 2027 / 2186s | 1040 / 1171 / 1315s | | vendor objects slot-time (noise reference) | 480 / 598 / 659 / 622s | 463 / 664 / 618s | | wall | 142 / 143 / 175 / 189s | 105 / 131 / 132s | | bun's own object files | 1.9 GB | 88 MB | | `libbun-profile.a` | 2051 MB | 121 MB | One pair without LTO (the `bun run build:release` configuration): bun's own C++ slot-time 1888s -> 1118s, wall 176s -> 119s, objects 1.67 GB -> 83 MB, archive 1833 MB -> 118 MB. The archive row is CI's build-cpp artifact: in build 91391 `gzip -1` of it took ~21s of build-cpp's 25s upload step, and downloading plus gunzipping it took ~13s of build-bun's wait step, before the ThinLTO link reads it. On the link side, `bun-profile` from a local release build carried 740 MB of `.debug_*` sections; the CI LTO lanes finish their link edge with a single-threaded `llvm-objcopy --compress-debug-sections=zlib` over that file, which took 27s on this machine (the WebKit prebuilt's own ~400 MB of DWARF remains, so that pass shrinks rather than disappears). I have not measured the link itself; it ingests ~1.7 GB less debug metadata, so it should get faster too, and the CI run of this PR will show the build-cpp, wait, link and package numbers directly. Per TU, the cost was a roughly constant 10-15s of DWARF emission for the PCH's type universe regardless of how much code the file contained: `codegen/GeneratedFakeTimersConfig.cpp` (51 lines) compiled in 16s to a 15 MB object; small two-file bundles produced 12-13 MB objects with ~4 KB of text. ### What changes for consumers of release debug info Release `bun-profile` binaries keep symbol tables, line tables and inlining information, which is what crash backtraces, `llvm-symbolizer`, ASAN/LSAN reports (the asan lane is a release build, so it gets this too) and the order-file tooling use, and it is the same level the Rust half already ships (`debug = "line-tables-only"` in Cargo.toml). What goes away is C++ type and variable information in release binaries, so stepping through release C++ in lldb shows frames and lines but not locals; the debug profile is unchanged. ### Effect on the shipped code Measured in https://github.com/oven-sh/bun/pull/37376#issuecomment-5252153542: same commit built both ways (ThinLTO, the release flag set), ThinLTO import lists identical, pre-LTO IR identical modulo debug info, and the final .text differs in 7 vendored functions (192 bytes, spill placement and instruction selection, smaller with this PR in every case); interleaved benchmarks of the two stripped binaries show no measurable runtime difference. Everything else in the binary is unchanged apart from the debug sections. ### Test `test/internal/build-debug-info-flags.test.ts` evaluates the flag tables for linux release/debug and a darwin release target and checks that the level flag is the last `-g` flag in bun's and the deps' C and C++ flag lists. It fails on main (`["-g1", "-glldb"]`) and passes with this change. --- **no test proof** · iteration 0 · Platform-specific test-only change; deferring to CI. --- scripts/build/flags.ts | 17 ++- test/internal/build-debug-info-flags.test.ts | 113 +++++++++++++++++++ 2 files changed, 125 insertions(+), 5 deletions(-) create mode 100644 test/internal/build-debug-info-flags.test.ts diff --git a/scripts/build/flags.ts b/scripts/build/flags.ts index 59e199b6e579..457b44391c75 100644 --- a/scripts/build/flags.ts +++ b/scripts/build/flags.ts @@ -285,6 +285,18 @@ export const globalFlags: Flag[] = [ when: c => c.darwin, desc: "DWARF 4 debug info (dsymutil-compatible)", }, + { + // Must stay ahead of the -gN entries below: every -g flag clang sees + // resets the debug-info level, and -glldb (like plain -g) selects the + // full standalone kind.

For bun's own types that is one of bun's objects; for JSC/WTF types it is the WebKit debug prebuilt, and I checked that those archives actually carry the homed definitions rather than relying on bun's copies: in both the linux debug-asan and the macos-arm64 debug-asan `libJavaScriptCore.a`, `JSC::JSObject` appears as a full definition (`DW_AT_byte_size`, `runtime/JSObject.h:102`) in two members and as a declaration in ~150 others, i.e. WebKit's own build is already homed and the definitions bun-debug needs are in the link. Debuggers see the same types and variables as before; the one thing homing gives up in general is types whose defining object has no debug info anywhere in the link, which is the normal state of affairs for debug builds on Linux. With the `-g1` fix in #37376, release builds are line tables and have no type definitions to home, so the entry is debug-only. ### Measurements (12-core shared box, ccache disabled) Fresh debug C++ build (`ci-cpp-only` mode with `--build-type=Debug`: deps, PCH, bun's C++, archive; no cargo), standalone vs homing back to back: | | before | after | |---|---|---| | bun's own C++ slot-time | 1757s | 1165s (-34%) | | all edges | 2245s | 1592s (-29%) | | wall | 150s | 114s (-24%) | | bun's own objects (`.debug_*` is zstd-compressed in both) | 1245 MB | 772 MB | `BunObject.cpp` alone, best of 3: 8.2s -> 5.35s (the same file with line tables only is 5.25s, with `-g0` 4.2s). A full `bun bd` relink afterwards: `bun-debug` 951 MB -> 782 MB. The debug build is throughput-bound on its C++ (cargo's 68s critical path finishes under it), so this shows up roughly 1:1 in fresh `bun run build` time, and every incremental debug compile gets the same per-TU saving. `clang -###` with the resulting debug `cxxflags` shows `-debug-info-kind=constructor` (was `standalone`). The test checks the flag is present in bun's and the deps' debug flag lists and absent from release. --- **no test proof** · iteration 0 · Platform-specific test-only change; deferring to CI. --------- Co-authored-by: Jarred Sumner --- scripts/build/flags.ts | 15 +++++++++++++++ test/internal/build-debug-info-flags.test.ts | 12 ++++++++++++ 2 files changed, 27 insertions(+) diff --git a/scripts/build/flags.ts b/scripts/build/flags.ts index 457b44391c75..4557535c2e2c 100644 --- a/scripts/build/flags.ts +++ b/scripts/build/flags.ts @@ -304,6 +304,21 @@ export const globalFlags: Flag[] = [ when: c => c.unix && c.debug, desc: "Full debug info, zstd-compressed", }, + { + // -glldb implies -fstandalone-debug: every TU emits the definition of + // every type it can see, i.e. the whole JSC/WTF universe the PCH pulls + // in, again.

Node (v26) prints `nextStreamID = 1` and `response on stream 1 200`: the native call is a no-op there because nghttp2 rejects id 0. ### Cause `setNextStreamID` in `http2.ts` mirrors node's wrapper (`validateNumber` plus `id <= 0 || id > 2 ** 32 - 1`), so a fractional id in (0, 1) is accepted and arrives in `H2FrameParser::set_next_stream_id` as 0 after `to_u32()`. The setter stores the id to step from by subtracting 1 or 2, which underflows for 0 (and the client branch special-cased 1 for the same reason). `get_next_stream_id` has the same problem in the other direction: the setter accepts the whole u32 range, and once a server session is parked at `2 ** 32 - 1`, computing the next id (`session.state`, `pushStream`) adds past `u32::MAX`: ``` panic: attempt to add with overflow ::get_next_stream_id ``` On release that wraps to 0, which `state.nextStreamID` then reports. Today this second site is only reachable through the native handle, because `ServerHttp2Session` does not expose `setNextStreamID` (node does; tracked separately), but it is the same arithmetic. ### Fix Both steps use `saturating_sub` / `saturating_add` (`src/runtime/api/bun/h2_frame_parser.rs`). An id with nothing to step back from lands on the initial state, so `setNextStreamID(0.5)` leaves a fresh client on stream 1 like node; a parked-out server reads back as an id above `MAX_STREAM_ID`, which `getNextStream` / `request` already reject as out of streams. The `== 1` special case in the setter and the unreachable `== 0` arm in the getter (0 is even) go away with it. No JS change: the wrapper already matches node's validation. ### Verification New test `http2 setNextStreamID at the edges of the id space does not overflow` in `test/js/node/http2/node-http2.test.js` spawns a fixture that sets 0.5 and 1 on a client, 0, 2 and `2 ** 32 - 1` on a server session, and reads `state.nextStreamID` after each. Without the fix it aborts with the panics above on a debug build, and on the release binary (`USE_SYSTEM_BUN=1`) it fails on the server values (`0` where `2` and `4294967295` are expected). With the fix it passes, along with the rest of `node-http2.test.js` and the ported `test-http2-client-setNextStreamID-errors.js`, `test-http2-no-more-streams.js`, `test-http2-client-destroy.js` and `test-http2-session-stream-state.js`. --- **[review]** gate passed · iteration 0 · 2 files touched

Unlike `"bun"`, these imports are not rewritten by the transpiler, so every `import process from "node:process"` (a very common line in published ESM packages) and every `import { createRequire } from "node:module"` paid for it. ## Repro ```js // entry.mjs import { describe } from "bun:jsc"; import process from "node:process"; import { createRequire } from "node:module"; // describe() dumps an object's Structure, i.e. which of its static table entries have been constructed so far. const entries = object => describe(object).match(/\{[^}]*\}/)[0].split(",").length; console.log(entries(process), entries(globalThis.process.getBuiltinModule("node:module"))); ``` Before: `86 27`. For `process` that is everything in the table that can be reified, including `stdout`, `stderr` and `stdin`, which construct the stdio streams and load `node:tty` / `node:stream` to do it, plus `config`, `release`, `allowedNodeEnvironmentFlags`, `versions`, ...; for `Module` it is `_cache`, `builtinModules`, `globalPaths`, `SourceMap`, the `wrapper` proxy and the rest of the table. After: `2 3`, i.e. only what is there before user code runs (`Symbol.toStringTag` and `_exiting` on `process`, `length` and `name` on `Module`) plus `createRequire`, the one thing the file imported. On this machine (release build of 1.4.0, min of 20 runs), `import process from "node:process"` added about 18 ms to the startup of an otherwise empty file, about the same as touching `process.stdout` does; with this change the import itself is free and that cost moves to whoever actually reads `stdout`. Measured numbers (release 1.4.0 for the eager cost, a debug build of this branch for the new one) are in a comment below. ## Fix Both generators move to the `BUN_FOREACH_LAZY_ESM_NATIVE_MODULE` group added in #37714 (the entries keep their position in `NativeModuleList.h`, so the generated ids do not change) and share one helper, `exportObjectProperties()` in `_NativeModule.h`, which the `"bun"` generator now uses too. For each name the caller wants exported it does the split #37525 does for the `src/js` builtins: a value that is already stored on the object (`getDirect()` finds a plain value) is exported as is, anything else is declared without a value and JSC's `materializeLazyExport` reads `object[name]` the first time something binds to it. "Anything else" covers a static table entry nobody has read yet (the expensive case), an accessor (`process.argv`, `process.title`, `Module._resolveFilename`, `Module.wrapper`), and a property inherited from the prototype chain (the EventEmitter methods of `process`). The generators themselves only decide the name list, which is what keeps the export lists identical to before: - `node:process`: `getPropertyNames()` on `process`, as before, so the inherited EventEmitter methods (`on`, `emit`, ...) stay exports, and a data property assigned onto `process` before the module is loaded is still exported and still snapshotted at load (`process.test.js` has a test for exactly that, with `default` on top, which keeps being skipped in favour of the object). - `node:module`: the static table, as before, so `length`, `name` and anything user code assigned onto `Module` stay out. - `"bun"`: `getOwnNonIndexPropertyNames()`, as in #37714. The only difference from #37714 is that a `Bun.*` property something already read before the module loads is now snapshotted instead of declared lazily; it is the same object either way. The generators no longer run any getters, so the `TopExceptionScope` handling that turned a throwing getter into an `undefined` export (and the comments about not bulk-reifying because of the exception-check verifier) go away with them. A getter that throws now throws from whatever binds to that export, and a termination arriving while a binding is being materialized propagates from there, the same way #37714 describes for `"bun"`. The sampling-time difference is also the same as there: an accessor export is read when it is first bound rather than when the module loads, which for the first importer is the same moment. ## Tests Added to `test/js/bun/resolve/builtin-esm-lazy-exports.test.ts`, same shape as the `"bun"` cases (each in its own process, readout is `describe()` of the object filtered to a watched sample of names; `Object.keys` / `Reflect.ownKeys` are used for the export-list checks because `for...in` reifies every static property of the object it enumerates): - `node:process`: linking `import proc, { on, release }` constructs exactly `release`; `on` is the inherited method; the export list equals the enumerable names of `process` and its prototype chain plus `default`; listing it constructs nothing; reading `stdout` off the namespace constructs exactly `stdout` and is the real stream; `argv` (an accessor) binds to `process.argv`. - `node:process`: a data property assigned before the load is exported with its value at load time, and one assigned afterwards is not exported (the part of the behaviour this keeps from the eager version). - `node:module`: linking `import Module, { createRequire }` constructs exactly `createRequire` (and it works); the export list equals `Object.keys(Module)` plus `default`; reading `builtinModules` constructs exactly that and is the same array; `_resolveFilename` binds to the accessor's value. The two "linking constructs ..." cases fail on main (everything watched shows up as constructed after import); the snapshot case and the 12 existing cases in the file pass on both. Also run on this build: `test/js/node/process/` (`process.test.js`, `process-stdio`, `process-on`, `call-constructor`, which imports `node:process` as ESM), `test/js/node/module/`, `test/js/node/events/event-emitter.test.ts`, `test/js/bun/util/BunObject.test.ts`, `test/js/bun/test/mock/`, `stubs.test.js`, `require-esm-transitive-tla` and `import-meta-resolve`; green except for two tests that fail identically without this change in this environment (`process.test.js` "process" wants `$USER` set, and `process-args.test.js` spawns 100 debug processes inside a 5 s timeout). `BUN_JSC_validateExceptionChecks=1` is clean for importing both modules and for reading every export of both namespaces. --- src/jsc/bindings/BunObject.cpp | 22 +-- src/jsc/modules/NativeModuleList.h | 12 +- src/jsc/modules/NodeModuleModule.cpp | 42 +---- src/jsc/modules/NodeModuleModule.h | 6 +- src/jsc/modules/NodeProcessModule.h | 35 +---- src/jsc/modules/_NativeModule.h | 37 +++++ .../resolve/builtin-esm-lazy-exports.test.ts | 145 ++++++++++++++++-- 7 files changed, 190 insertions(+), 109 deletions(-) diff --git a/src/jsc/bindings/BunObject.cpp b/src/jsc/bindings/BunObject.cpp index 062882b38a82..04c1c4ca808b 100644 --- a/src/jsc/bindings/BunObject.cpp +++ b/src/jsc/bindings/BunObject.cpp @@ -42,6 +42,7 @@ #include "GeneratedBunObject.h" #include "JavaScriptCore/BunV8HeapSnapshotBuilder.h" #include "BunObjectModule.h" +#include "_NativeModule.h" #include "JSCookie.h" #include "JSCookieMap.h" #include "Secrets.h" @@ -1151,9 +1152,6 @@ JSC::JSObject* createBunObject(VM& vm, JSObject* globalObject) } // namespace Bun namespace Zig { -// Every export except `default` is declared without a value: JSC reads `Bun[name]` the first time -// something binds to it (SyntheticModuleRecord::materializeLazyExport), so importing the module does -// not run the PropertyCallbacks in bunObjectTable, most of which construct a class or load a builtin.

``` `RunCommand::boot` and `RunCommand::boot_standalone` each turned the entry path `Box<[u8]>` into a raw pointer with `heap::into_raw` and dereferenced it again for `set_main`, wrote the three pointers into `RUN` with `ptr::write`, defined an identical `extern "C" fn trampoline` that re-derived `&mut Run` from the `c_void`, called the `#[deprecated]` `hold_api_lock` under `#[allow(deprecated)]`, and ended in an unreachable `Ok(())`. `Run::start` and `Run::add_conditional_globals` then dereferenced all three fields once more, each with its own SAFETY comment, and a six line comment explained why `ANY_UNHANDLED` could not be a field of `Run`. `Run` is now a stack local built as the tail expression of both boot functions: ```rust pub struct Run<'a> { ctx: &'a ContextData, vm: &'a mut VirtualMachine, entry_path: &'static [u8], } fn start(self) -> ! { let Run { ctx, vm, entry_path: mut entry } = self; let _api_lock = vm.global().vm().get_api_lock(); ... } ``` Both boot sites bind `let entry: &'static [u8] = Box::leak(entry_path);` once and set `vm.main` from it. `boot` keeps the same two values it had before: `entry` is still the user's path and still feeds the `main_is_html_entrypoint` loader check after the cron branch, while the former `entry_ptr` (the path `Run::start` hands to `load_entry_point`, swapped for the synthetic `cwd/[eval]` path in cron mode) is now `let mut run_entry = entry;` and ends up in `Run { ctx, vm, entry_path: run_entry }.start()`; `boot_standalone` has a single path and passes `entry` directly. `start` diverging makes the `Ok(())` tails dead, so they are deleted. `start` takes the lock through the non-deprecated `VM::get_api_lock` guard (`vm.global()` returns `&'static JSGlobalObject`, so the guard does not borrow the Rust `VirtualMachine`), and the rest of its body is unchanged apart from the two `enable_hot_module_reloading` calls, which pass `ptr::from_mut(vm)` exactly as `test_command.rs` already does, and the call to `add_conditional_globals`, which is now `fn add_conditional_globals(vm: &VirtualMachine, ctx: &ContextData)`. Deleted: the `RUN` static, both trampolines, both `#[allow(deprecated)]`, both `Ok(())` tails, the `c_void` import and 11 unsafe blocks (2 `into_raw` derefs, 2 `RUN` writes, 2 trampoline derefs, 5 field derefs in `start`/`add_conditional_globals`); no unsafe is added. One file, 52 insertions, 128 deletions. Left as is on purpose: the four cpu/heap profiler `&'static [u8]` launders in `start` (they need `boot` to take `&'static mut ContextData`, which ripples through `Command::start`), and the remaining `hold_api_lock` users in `repl_command.rs` and `jsc/Debugger.rs`, which have their own context structs. ## Why The types now state what the comments used to: `start` has a shared borrow of the CLI context and the exclusive borrow of the VM that `boot` already held, the entry path is `'static` because `vm.main` and the hot reloader keep pointing at it, and `Run` cannot exist before `boot` has finished initialising the VM or be observed half written, because there is no longer a static to observe. `JSC__VM__getAPILock` runs the same `JSLock::lock()` that the `JSLockHolder` inside `JSC__VM__holdAPILock` ran, and neither shape ever unlocks (the callback never returned before; the guard is never dropped now, and the workspace builds with `panic = "abort"`); `Box::leak` is `Box::into_raw` plus a reborrow; the three words move from a BSS static into the caller's frame and one indirect call through the trampoline disappears. The only difference in the machine state is that the lock is taken from `start`'s frame instead of from inside the two removed shim frames, which shifts the stack position JSC records at lock acquisition by a few dozen bytes, the same kind of variation any edit to these functions' locals produces. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates.

The same record problem shows up in other shapes: - `export { readFileSync as rfs } from "node:fs"` in a bundled file: `typeof rfs` is `"undefined"` in the compiled binary. - `import { join } from "node:path"` in a file that also assigns `module.exports` (so it gets the `__commonJS` wrapper): `ReferenceError: join is not defined`. - `export * from "node:path"` / `export * as ns from` / `export { x } from` an external on an entry point (or on a split chunk, where it becomes observable through `import()`): the star export is missing and the tail exports are recorded as `[Local]` instead of `[Namespace]` / `[Indirect]`. In a split chunk this is the same TDZ error as above. Debug builds cross-check the record against JSC's own analyzer and refuse to start the binary in every one of these cases: `error: Imports different between parseFromSourceCode and fallbackParse`. ## Cause With `--compile --bytecode --format=esm`, JSC does not parse the chunk; its `JSModuleRecord` is built from a `ModuleInfo` the linker assembles. `post_process_js_chunk` filled in the external imports by scanning the pre-link AST for `SImport` statements. That scan does not see what is actually printed: - `convert_stmts_for_chunk` rewrites `export * as ns from ""` and `export { x } from ""` into `import` statements at print time (and, with `CALLS_RUNTIME_RE_EXPORT_FN`, `export * from` too), so those are `SExportStar` / `SExportFrom` in the AST and were never recorded. - `export * from ""` kept verbatim on an entry point needs a star export entry; nothing added one. - Files with `wrap == Cjs` were skipped entirely, but their ESM imports are hoisted out of the wrapper and printed. - It also had to be taught about tree-shaken parts separately (#37619), and it ignored loader attributes and `import defer`, which the printer handles. Every missing import entry leaves the binding uninitialized in the module environment (or resolves it as a global), hence the TDZ error / `undefined` / `is not defined`. ## Fix Stop re-deriving the record from the AST and record what is printed. Each part range printed by `generate_compile_result_for_js_chunk` now gets its own `ModuleInfo` (the printer already records every `import` / `export ... from` statement it prints, plus `import.meta`), carried on `CompileResult::Javascript`. `post_process_js_chunk` appends them to the chunk's `ModuleInfo` in `parts_in_chunk_in_order` order, after the cross-chunk prefix imports and before the suffix / entry point tail exports, so the requested modules end up in the same order JSC's parser would produce from the chunk source. `ModuleInfo::finalize` then turns the tail's `export { ns, readFileSync as rfs }` into the namespace / indirect exports JSC expects, since the matching import entries now exist. `ModuleInfo::append` (new, in the printer crate next to the other builders) re-interns the appended record's strings, copies sentinel slots and fetch parameters through, and applies the same first-export-wins rule as `add_export_info_*`. The top-level await flag is still derived from the AST because the printer does not track it; the `import.meta` flag now comes from the printer, which sets it at the only places it prints `import.meta`. The three-clause "is this an ESM bytecode compile build" condition that was repeated in four places is now `LinkerOptions::generates_module_info()`. `CompileResult`'s unused `Clone` impl is removed rather than given a lossy clone of the new field. The `parts_live` check from #37619 goes away with the loop it was added to; the per-part printer only prints live parts, and that PR's tests still pass here. Second commit: `print_binding` and the function/class statement arms interned every declared name into the record's string table before checking whether the declaration was exported. With module info now attached to the per-part printer, that would have put every binding name in the bundle into the embedded record (which JSC atomizes at startup), so those arms now check for the export first and only intern names they record. The records themselves are unchanged; this also applies to the runtime's `--isolate` module records, which go through the same arms. This is correct because the record's only job is to describe the chunk text that was bytecode-compiled; deriving it from the printer makes it match by construction instead of mirroring `convert_stmts_for_chunk`'s rewrites by hand. It also means changes that would otherwise have to teach the removed loop about skipped statements (such as the external import dedupe in #35635 / #35645) no longer need to. One intentional difference: browser-side chunks of a full-stack `--compile` build are printed with the browser target, so their (never loaded as modules, served as assets) records now only carry the cross-chunk entries; a `Bun.serve` + HTML import binary built with these flags still builds and serves. ## Verification New tests, all failing before this change (release: the errors above; debug: the cross-check error) and passing after: - `test/bundler/bundler_compile.test.ts`, ESM bytecode matrix (each runs plain and minified): `ReExportExternalFromInlinedModule`, `ReExportExternalFromEntryPoint`, `ExternalImportInCommonJSWrapper`. - `test/bundler/bundler_compile_splitting.test.ts`: `ReExportExternalFromSplitChunk` (+minify), which also covers appending after the cross-chunk prefix imports. With the debug build: the rest of `bundler_compile.test.ts` (including the existing `ImportMeta` / TLA / `import defer` bytecode scenarios, which now exercise the printer-derived `import.meta` flag), all of `bundler_compile_splitting` (including #37619's `DeadExternalImportInWrappedModule` matrix), `bundler_barrel` `ESMBytecodeCompileSkipsDeferredImports`, `test/js/bun/typescript/type-export.test.ts`, `bun-build-compile`, `bundler_bun`, `regression/issue/26298`, `esbuild/importstar` + the splitting suites, and for the runtime record path `test/cli/test/isolation.test.ts` and `test/cli/run/transpiler-cache.test.ts` pass. For the string table, a compiled fixture with a non-exported function, parameter and local was checked with `grep -c` on the output binary: each name occurs exactly as often as in a binary produced by the released 1.4.0 (source text plus bytecode), i.e. the record does not pick them up. `compile/HelloWorldWithProcessVersionsBun` fails locally both with and without this change. --- src/bundler/Chunk.rs | 7 - src/bundler/LinkerContext.rs | 13 ++ src/bundler/analyze_transpiled_module.rs | 5 - src/bundler/bundle_v2.rs | 48 +--- .../linker_context/OutputFileListBuilder.rs | 8 +- .../generateChunksInParallel.rs | 10 +- .../generateCodeForFileInChunkJS.rs | 4 + .../generateCompileResultForJSChunk.rs | 10 + .../linker_context/postProcessJSChunk.rs | 211 ++++-------------- src/js_printer/lib.rs | 107 ++++++--- test/bundler/bundler_compile.test.ts | 53 +++++ .../bundler/bundler_compile_splitting.test.ts | 29 +++ 12 files changed, 243 insertions(+), 262 deletions(-) diff --git a/src/bundler/Chunk.rs b/src/bundler/Chunk.rs index d4bb3972c702..8f0e8acd8a62 100644 --- a/src/bundler/Chunk.rs +++ b/src/bundler/Chunk.rs @@ -1591,13 +1591,6 @@ pub mod bun_renamer { } impl ChunkRenamer { - pub(crate) fn name_for_symbol(&mut self, ref_: bun_ast::Ref) -> &[u8] { - match self { - ChunkRenamer::None => unreachable!("ChunkRenamer not initialized"), - ChunkRenamer::Number(r) => r.name_for_symbol(ref_), - ChunkRenamer::Minify(r) => r.name_for_symbol(ref_), - } - } pub(crate) fn as_renamer(&mut self) -> bun_js_printer::renamer::Renamer<'_, '_> { match self { ChunkRenamer::None => unreachable!("ChunkRenamer not initialized"), diff --git a/src/bundler/LinkerContext.rs b/src/bundler/LinkerContext.rs index e6306c343c80..bbe0441b4548 100644 --- a/src/bundler/LinkerContext.rs +++ b/src/bundler/LinkerContext.rs @@ -1268,6 +1268,17 @@ pub struct LinkerOptions { pub(crate) public_path: &'static [u8], } +impl LinkerOptions { + /// ESM bytecode in a `--compile` build: JSC does not parse the chunk, so + /// its `JSModuleRecord` is built from a `ModuleInfo` the linker records + /// while printing (see `post_process_js_chunk`). + pub(crate) fn generates_module_info(&self) -> bool { + self.generate_bytecode_cache + && self.output_format == Format::Esm + && self.compile_mode.is_executable() + } +} + impl Default for LinkerOptions { fn default() -> Self { Self { @@ -2142,6 +2153,7 @@ impl<'a> LinkerContext<'a> { runtime_require_ref: Option, source_index: Index, source: &Source, + module_info: Option<&mut crate::analyze_transpiled_module::ModuleInfo>, ) -> js_printer::PrintResult { let parts_to_print = &[Part { stmts: bun_ast::StoreSlice::new_mut(out_stmts), @@ -2221,6 +2233,7 @@ impl<'a> LinkerContext<'a> { None }, mangled_props: Some(mangled_props), + module_info, ..Default::default() };

For reference, `cargo --timings` on the non-LTO configuration shows 137s of a 159s build with at most two units running. Nothing built with ASAN ships, so that profile uses cargo's release default of 16 codegen units (`-Zbuild-std`'s std gets the same). Every other configuration is untouched — the env var is only set inside the existing asan branch; a `release-asan` configure shows `CODEGEN_UNITS=16` alongside `LTO=off`, and the release/LTO configurations set neither. Local `release-asan` builds get the same speedup. The trade is intra-crate inlining of non-`#[inline]` functions in the asan binary — the stock cgu=1 vs cgu=16 difference — so the two numbers to look at on this PR's build are the `linux-x64-asan-build-bun` time (baseline ~5m20–5m35) and the asan test lane's wall clock, which should not move meaningfully. Will fill both in from CI. --- scripts/build/rust.ts | 2 ++ 1 file changed, 2 insertions(+) diff --git a/scripts/build/rust.ts b/scripts/build/rust.ts index 4e3a41ae477f..e13430a52cf8 100644 --- a/scripts/build/rust.ts +++ b/scripts/build/rust.ts @@ -686,6 +686,8 @@ export function cargoBuildInvocation(cfg: Config): CargoInvocation { // cargo step vs 4m36s for the linker-plugin-lto build (which defers // codegen to lld).

The C++ objects are still archived into `libbun-*.a` and the link reads that archive, exactly as `rust-and-link` did with the downloaded one, so the shipped binary is linked the same way as before. - `libbun-*.a` (gzipped), `libbun_rust.a` (gzipped) and the dep libs are uploaded from ninja edges that depend only on their input, so each upload starts the moment the file exists and overlaps the rest of the build (dep libs during the compile, the archive during cargo, the rust lib during the link). The intermediates the split uploaded are still there for reproducing a link locally. - Test shards download `*.zip` from `build-bun` instead of `**`, so they don't pull the archive/dep libs now that those live on the same step. - `cpp-only` / `rust-and-link` modes and `.buildkite` plumbing for them are left in place until the timings from this layout are in; if it holds up they can be deleted in a follow-up. - asan builds get full (homed, zstd-compressed) debug info again — #37376 dropped them to line tables together with the other release builds, and looking at variables in asan builds is worth the compile time. `test/internal/build-debug-info-flags.test.ts` pins it. ### Baseline (build 92784 on main, plus asan from PR builds) | lane | build-cpp | build-bun | |---|---|---| | linux-x64 | 1m38 | 5m28 | | linux-aarch64 | 1m37 | 5m22 | | darwin-aarch64 | 1m12 | 5m39 | | darwin-x64 | 1m24 | 5m36 | | windows-x64 | 1m31 | 5m44 | | windows-aarch64 | 1m51 | 5m41 | | linux-x64-asan (full DWARF, pre-#37376) | ~3m00 | ~5m30–5m45 | | linux-x64-asan (line tables, post-#37376) | 2m28 | 5m34 | ### Results (build 92801; second column of "after" is a retry of the same job where I took a second sample) | lane | before: build-cpp / build-bun (ran in parallel) | after: build-bun | lane wall-clock | agent-minutes | |---|---|---|---|---| | linux-x64 | 1m38 / 5m28 | 4m51 | -37s | -2m15 | | linux-aarch64 | 1m37 / 5m22 | 4m55 | -27s | -2m04 | | linux-x64-musl | 1m36 / 5m21 | 4m55 | -26s | -2m02 | | linux-aarch64-musl | 1m34 / 5m24 | 4m44 | -40s | -2m14 | | darwin-aarch64 | 1m12 / 5m39 | 4m56 | -43s | -1m55 | | darwin-x64 | 1m24 / 5m36 | 5m05 | -31s | -1m55 | | windows-x64 | 1m31 / 5m44 | 5m21 | -23s | -1m54 | | windows-aarch64 (non-LTO) | 1m51 / 5m41 | 6m00, 6m45 | +19s / +1m04 | -1m32 / -47s | | linux-x64-android (non-LTO) | 1m40 / 6m10 | 6m01 | -9s | -1m49 | | linux-aarch64-android (non-LTO) | 1m30 / 5m31 | 5m35 | +4s | -1m26 | | freebsd-aarch64 (non-LTO) | 1m33 / 5m25 | 5m27 | +2s | -1m31 | | freebsd-x64 (non-LTO) | 1m30 / 5m08 | 6m13, 5m41 | +1m05 / +33s | -25s / -57s | | linux-x64-asan (non-LTO, now with full DWARF again) | 2m28 / 5m34 | 5m55, 5m43 | +21s / +9s | -2m07 / -2m19 | 26 -> 13 build agents per build, ~93 -> ~69 agent-minutes. Every ThinLTO lane is 25-45s faster than the old build-bun alone; the non-LTO lanes (where the C++ compile is real codegen rather than bitcode emission, so it competes harder with cargo) range from flat to about a minute slower, windows-aarch64 and freebsd-x64 being the noisy/slow ones. Those could get a bigger instance if it matters. Breakdown of the linux-x64 step from the ninja log: ~20s checkout+configure, cargo ~2m10 with the whole C++ compile + archive + its upload finishing inside that window, ThinLTO link ~1m46, package+upload ~30s.

At `3fc747a7da`: * generated thunk `extern "C" fn ${name}__finalize(this: &mut ${name})` (src/codegen/generate-jssink.ts), called from `~JS${name}`, `~JSReadable${name}Controller` and `${name}__doClose` * `JSSink::js_finalize(this: &mut T)` (src/runtime/webcore/Sink.rs) * `JsSinkType::finalize(&mut self)` (src/runtime/webcore/Sink.rs), whose impls do the actual release: * `ArrayBufferSink` (src/runtime/webcore/ArrayBufferSink.rs): `Self::finalize(ptr::from_mut(self))` -> `destroy` -> `heap::take`, unconditionally. The comment on the impl said the C export owned the free; this call is the free. * `FileSink` (src/runtime/webcore/FileSink.rs): the inherent `finalize(&mut self)` ends in `FileSink::deref(ptr::from_mut(self))`, which runs `deinit` -> `heap::take` whenever the wrapper's +1 was the last ref, i.e. on an ordinary GC sweep of a sink nothing else holds. The header comment argued this was fine because the `&mut` carries write provenance, which is true but is not the problem. * `FetchRequestBodySink` (src/runtime/webcore/fetch/FetchRequestBodySink.rs): drops the tasklet ref taken in `start_request_stream`. The tasklet owns the sink allocation, so if that ref is the last one, `FetchTasklet::deinit` -> `clear_data` -> `clear_sink` -> `heap::take(sink)` frees `*self` inside the call. That is the fallback path for a pump that never settled; it is reachable at least on worker teardown: phase B of `VirtualMachine` teardown releases the aborted fetch's other refs on the tasklet, and phase C then destroys the heap, sweeping the controller with `m_sinkPtr` still set because `JSSinkController__onClose` does not run the detaching JS callback once termination is pending. * `HTTPServerWritable`, `NetworkSink` and `RewriterPipe` do not free anything here (their allocations are owned by the `RequestContext`, the S3 wrapper and the pipe's own refcount respectively). A reference passed as an argument has to stay dereferenceable until the call returns. Freeing it from inside the call is undefined behaviour under both aliasing models whether or not the reference is used again (Stacked Borrows: `deallocating while item is strongly protected`; Tree Borrows, which `bun run rust:miri` uses, rejects it the same way), and that protector is the model behind the `dereferenceable` attribute rustc puts on every `&`/`&mut` argument, so the optimizer may legitimately move a load through any of the three frames past the free. No crash is known from this; ASAN only has something to catch if the optimizer actually takes that liberty, which the unoptimized debug build never does, so it is not observable as a runtime test. Same family as #37672, #37681, #37685, #37693, #37705 and #37551; #37705's description leaves this chain out explicitly because it needs a change to the generated thunk. ### Fix The whole chain takes the raw pointer, which is what the C++ side has anyway (`void* m_sinkPtr`): * generate-jssink.ts emits `pub unsafe extern "C" fn ${name}__finalize(this: *mut ${name})` forwarding to `js_finalize`; the ABI is unchanged, so JSSink.cpp is untouched. * `JSSink::js_finalize(this: *mut T)` forwards to the trait. * `JsSinkType::finalize` becomes `unsafe fn finalize(this: *mut Self)`, documented as "the cell is giving up its claim; this may free the sink", the same shape as `HTTPServerWritable::abort(this: *mut Self)` and the FileSink PipeWriter callbacks. * The three freeing impls release through the pointer without forming a reference to the allocation: `ArrayBufferSink` calls `destroy` directly (the inherent `finalize` wrapper, whose only caller was the trait impl, is deleted); `FileSink::finalize(this: *mut FileSink)` keeps the same body with per-statement `(*this).field` access, like `on_close` in the same file (the file header no longer claims the `&mut` version was sound; the rationale lives once, on the trait method); `FetchRequestBodySink::finalize(this: *mut Self)` takes `task` out through the pointer and does not touch it after the deref. * `HTTPServerWritable` and `NetworkSink` reborrow inside their own impl to call the unchanged inherent `finalize(&mut self)`; that borrow ends before the impl returns and nothing under it frees, which the SAFETY comments state. `RewriterPipe`'s impl stays empty. Every impl performs the same operations in the same order as before; the only thing that moves is the type the pointer travels as. `js_controller_detached`, `js_close` and `js_end_with_sink` still take `&mut`: nothing frees under them (the `controller_detached` contract on the trait already requires deferring a last-owner free for that reason). `FileSink::assign_to_stream`'s `FileSinkRef` guard also derefs from a `&mut self` frame, but its ref is balanced against one it took itself and every caller (subprocess stdin setup) holds its own ref across the call, so it can never be the one that frees; left alone. Sites with the same shape outside this chain (`S3UploadStreamWrapper::handle_{resolve,reject}_stream`, `FetchTasklet::write_end_request`) are not sink frames and are reported separately. ### Tests test/internal/source-lints/jssink-finalize-raw-ptr.test.ts scans every `impl ... JsSinkType for ...` block for a `finalize` item and requires `unsafe fn finalize(: *mut Self)`, checks the other frames by signature (trait declaration, `js_finalize`, the codegen template, and the three inherent methods that perform the free, which `pub` tells apart from the trait impls in the same files), and checks its own patterns against positive and negative spellings. With src/ restored to `main` it reports: ``` src/runtime/api/html_rewriter.rs:1650: impl JsSinkType for RewriterPipe: fn finalize(&mut self) (line 1661) src/runtime/webcore/ArrayBufferSink.rs:213: impl JsSinkType for ArrayBufferSink: fn finalize(&mut self) (line 221) src/runtime/webcore/fetch/FetchRequestBodySink.rs:274: impl JsSinkType for FetchRequestBodySink: fn finalize(&mut self) (line 281) src/runtime/webcore/FileSink.rs:1283: impl JsSinkType for FileSink: fn finalize(&mut self) (line 1294) src/runtime/webcore/streams.rs:2104: impl JsSinkType for HTTPServerWritable: fn finalize(&mut self) (line 2119) src/runtime/webcore/streams.rs:2523: impl JsSinkType for NetworkSink: fn finalize(&mut self) (line 2530) src/runtime/webcore/Sink.rs: JsSinkType::finalize declaration does not take the sink as `*mut` src/runtime/webcore/Sink.rs: JSSink::js_finalize does not take the sink as `*mut` src/codegen/generate-jssink.ts: generated `${name}__finalize` thunk does not take the sink as `*mut` src/runtime/webcore/FileSink.rs: FileSink::finalize does not take the sink as `*mut` src/runtime/webcore/fetch/FetchRequestBodySink.rs: FetchRequestBodySink::finalize does not take the sink as `*mut` ``` (`ArrayBufferSink::destroy` already took `*mut` on `main`; its entry is a ratchet.) The behaviour itself is the existing coverage of each finalize path; see below. ### Verification Debug (ASAN) build on Linux: `cargo clippy -p bun_runtime` and `rustfmt --check` on the touched files are clean; the generated thunks have the new signature. Passing: test/internal/source-lints/ (all 18 files), test/js/bun/util/arraybuffersink.test.ts and filesink.test.ts (wrapper sweep and prototype `.close()` for the two Box/refcount sinks), test/js/bun/spawn/spawn.test.ts (stdin `FileSink` via `assign_to_stream`), test/js/web/fetch/body-stream.test.ts, fetch-abort-stream-body.test.ts and fetch-stream-cancel-leak.test.ts (`FetchRequestBodySink`), test/js/bun/http/serve-response-stream-sink-leak, serve-direct-readable-stream, serve-stream-reject-flush-leak and serve-async-stream-client-abort (`HTTPServerWritable` controller teardown), test/js/web/fetch/server-response-stream-leak.test.ts, test/js/web/streams/streams.test.js, test/js/workerd/html-rewriter.test.js and html-rewriter-leak.test.ts (`RewriterPipe`), test/js/bun/s3/s3-stream-error-gc.test.ts and s3-argument-validation.test.ts. The S3 upload tests that would drive `NetworkSink` (s3.test.ts, s3-storage-class.test.ts) cannot connect from this environment and fail identically on the released binary, so that impl (a one-line forward to the unchanged inherent method) is left to CI. Overlap with the sibling lints, each of which documents these sites as tracked separately: #37685 / #37693 / #37705 add `self-receiver-teardown.test.ts` with `src/runtime/webcore/ArrayBufferSink.rs: 1` allowlisted for the `Self::finalize(ptr::from_mut(self))` line this PR removes, and #37703 adds `self-receiver-release.test.ts` with `src/runtime/webcore/FileSink.rs: 2` allowlisted for the two derefs inside the old `FileSink::finalize(&mut self)` (running that lint against this branch reports FileSink.rs at 0). Whichever side lands second deletes the entry; nothing else conflicts (#37703's FetchRequestBodySink.rs hunk is `end_from_stream`, a different function). #34999 and #35528 edit the body of `FileSink::finalize` textually but keep the receiver. --------- Co-authored-by: Jarred Sumner --- src/codegen/generate-jssink.ts | 14 +++-- src/runtime/api/html_rewriter.rs | 2 +- src/runtime/webcore/ArrayBufferSink.rs | 30 +++-------- src/runtime/webcore/FileSink.rs | 54 +++++++++---------- src/runtime/webcore/Sink.rs | 18 +++++-- .../webcore/fetch/FetchRequestBodySink.rs | 15 ++++-- src/runtime/webcore/streams.rs | 14 +++-- 7 files changed, 78 insertions(+), 69 deletions(-) diff --git a/src/codegen/generate-jssink.ts b/src/codegen/generate-jssink.ts index 5555d32e7e59..d11702be1be4 100644 --- a/src/codegen/generate-jssink.ts +++ b/src/codegen/generate-jssink.ts @@ -1079,7 +1079,8 @@ function rustSink() { // `&`/`&mut ${name}` directly (ABI-identical to `void*` for non-null inputs; // every JSSink.cpp call site null-checks `m_sinkPtr`/`wrapped()` before // calling).

Node uses the OS `getnameinfo`, which treats `::ffff:a.b.c.d` as the IPv4 address `a.b.c.d`. ### Fix In `get_sockaddr` (whose only consumer is the `getnameinfo` path), detect the v4-mapped prefix (`::ffff:0:0/96`) after parsing and store the address as `AF_INET` with the embedded IPv4 octets, so c-ares does a normal `in-addr.arpa` lookup. ### Verification New test in `test/js/node/dns/node-dns.test.js` asserts `lookupService("::ffff:127.0.0.1", 53)` settles to the same outcome as `lookupService("127.0.0.1", 53)`. Fails on bun 1.3.x (`ENOTFOUND` vs `{ hostname: 'localhost', service: 'domain' }`), passes with this change.

Adding a top-level `debug` makes that peer satisfiable from the root and flips the frozen install from pass to fail, even though the lockfile is byte-identical across installs. ### Cause The frozen-lockfile check compares the loaded lockfile against the cleaned one with `Lockfile::eql`, which compares the hoisted trees. `Package::clone` (run by `clean_with_logger`) resets optional peer edges and lets `Tree::hoist_dependency` re-derive them, and that search is bounded at the bundle hoist root, so the bundled dependency's optional peer on `debug` stays unresolved, exactly as in a fresh install (which is why `bun.lock` has no `cdk8s/debug` entry). The bun.lock parser's `find_resolution` path walk had no such bound: it walked `cdk8s/follow-redirects/debug` -> `cdk8s/debug` -> `debug` and bound the edge to the root `debug`. The parse-side hoist then placed `debug` (and its dependency `ms`) under the bundle hoist root, producing tree placements a fresh install never generates: ``` eql: hoisted len mismatch l=7 r=9 ... R path="cdk8s" pkg="debug" res=3.2.7 R path="cdk8s" pkg="ms" res=2.1.3 ``` so `eql` returned false and the frozen install failed. ### Fix Bound the parser's path walk at the bundle hoist root for optional peer edges: once a directory on the upward walk is a bundled package, only one more level (the tree node containing the bundled package) is searched, matching `Tree::hoist_dependency`. The walk for other dependency kinds is unchanged, as is lockfile serialization. ### Verification - New fixture package `bundled-optional-peer` (bundles `optional-peer-deps`, which has an optional peer on `no-deps`) and a test in `test/cli/install/bun-lock.test.ts` that installs it together with `no-deps` and runs `--frozen-lockfile` twice (with and without `node_modules`). The test fails with `error: lockfile had changes, but lockfile is frozen` without the src change and passes with it. - The cdk8s repro above passes with the fix and still fails the frozen install when package.json actually changes. - `test/cli/install/bun-lock.test.ts`, `lockfile-version-2.test.ts`, and the bundled/peer suites in `bun-install-registry.test.ts` pass. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

Bun threw synchronously: ``` TypeError: The "undefined" argument must be of type number. Received null code: "ERR_INVALID_ARG_TYPE" ``` `{ all: null }` and `{ verbatim: null }` threw the same way. Node treats a null option field the same as an absent one (its guards are `!= null`). ### Cause In `src/js/node/dns.ts`, `validateFlagsOption`, `validateAllOption` and `validateVerbatimOption` only skipped `undefined`, so `null` fell through to `validateNumber`/`validateBoolean`. (`family` and `order` already handled null.) Additionally, the native getaddrinfo options parser (`src/runtime/dns_jsc/options_jsc.rs`) rejected a null `flags` value while already treating null `family`, `socktype`, `protocol` and `backend` as unset, so a null `hints` forwarded by `node:dns` would have failed there next. ### Fix - `dns.ts`: the three guards now skip null as well, matching Node's `!= null` checks. Non-null invalid values (`hints: "a"`, `all: 1`, `verbatim: 0`) still throw ERR_INVALID_ARG_TYPE. - `options_jsc.rs`: a null `flags` is treated as unset, consistent with the other fields. This overlaps with one bullet of #33516, which is a broader `lookup()` validation rework that has gone stale and now conflicts with main; this PR is just the null handling the issue reports. ### Verification New tests in `test/js/node/dns/node-dns.test.js` cover `{hints|all|verbatim|order|family: null}` for both `dns.lookup` and `dns.promises.lookup` (6 of 10 fail on the released binary), and `test/js/bun/dns/resolve-dns.test.ts` covers `Bun.dns.lookup` with `flags: null` (fails on the released binary). All pass with this change, and both files report the same pre-existing pass/fail counts as main otherwise (the failures are network-bound tests that cannot resolve external domains in this sandbox). --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

IPC handle passing (`process.send(msg, handle)`) is implemented on the way, since round-robin scheduling is built on it, and the upstream `child_process` tests that exercise it are ported too. | vendored suite | before | after | |---|---|---| | `test-cluster-*` (parallel + sequential) | 54 files | **85 files, 85/85 passing** (31 added, 14 re-synced to v26.3.0) | | `test-child-process-*` handle passing / fork | — | **12 added** (`fork-net-server`, `fork-net-socket`, `send-keep-open`, `pass-fd`, `internal`, advanced-serialization framing, …) | In total **43 upstream tests are added** (31 cluster + 12 child_process) and 15 existing ones re-synced, alongside ~41 new Bun-side test cases (`cluster.test.ts`, the new `child_process_ipc_handle.test.ts`, `child_process.test.ts`, `node-net.test.ts`, `spawn.ipc.bun-node.test.ts`). Numbers are local debug-build sweeps (Linux and macOS). Every vendored file is byte-identical to upstream; `test/expectations.txt` is untouched. ### Behavior changes - **Real round-robin scheduling (SCHED_RR)**: the primary owns the listen socket, accepts with reads paused (bytes stay in the kernel buffer, so data that arrives before the worker attaches is not lost), and hands each accepted fd to a worker over the IPC channel as SCM_RIGHTS ancillary data. Workers adopt Node's faux listen handle — `ref()`/`unref()` via timer, idempotent `close()`, `getsockname` from the primary's cached sockname — instead of binding their own socket. `newconn`/`accepted` replies, redistribution when a worker declines, and the `maxConnections` accept check match Node. Beyond Node: a connection that was in flight to a worker that *crashed* is handed to another worker instead of being leaked; after a graceful disconnect the primary just drops its copy; a live worker's `act:close` leaves the connection to its ack exactly as Node does. A peer that resets a queued connection no longer crashes the primary. - **SCHED_NONE / shared handles**: the primary binds (never listens) via a new native bind-only path, ships the fd to every worker that asks, and each worker does its own `listen(2)` on the duplicated fd (new `us_socket_group_listen_fd`, which validates before touching the descriptor's flags). Bind errnos are captured once and replayed to every worker (`EADDRINUSE` arrives as an `'error'` event with Node's `ExceptionWithHostPort` shape). `server.close()` in a worker releases its share immediately, so the same worker can re-listen; `server.address()` reports the shared unix path; abstract-namespace names bind with the exact length. A user-supplied `listen({ fd })` is validated the way Node's `createServerHandle` does — anything that cannot serve (non-sockets, connected stream sockets such as a spawned process's stdio, datagram sockets) is `EINVAL`, and the primary's own descriptor is left alone. - **UDP clustering**: dgram sockets in workers route non-exclusive binds through the primary's shared handle (UDP is never round-robin), including `bind({ fd })`; new native UDP-from-fd adoption (`us_create_udp_socket_from_fd`) and a `UDPSocket.fd` getter back it. A worker that fails to adopt the shared fd releases it. - **`cluster._getServer` query tuples** match Node's `listenInCluster`: pipes query as `(path, -1, -1)`, fds as `(null, null, null)`, `listen(port, host)` carries the real address/family, and `reusePort: true` forces `exclusive` (net and dgram) so each worker binds its own SO_REUSEPORT socket. Primary handle keys only get the per-listen `:index` suffix for port-0 listens, so fixed ports/pipes/fds share one handle across workers. `http.Server.listen()` in a worker reports `listening` to the primary (and stays quiet in a child that merely inherited `NODE_UNIQUE_ID` without a channel). - **IPC handle passing** (`child.send` / `process.send` / `worker.send` with a handle): `net.Socket`, `net.Server` and `dgram.Socket` handles cross the channel (fd via SCM_RIGHTS, the NODE_HANDLE ack protocol that already existed in the wire layer; the JS serialize/parse halves were stubs). Semantics follow `lib/internal/child_process.js`: a sent `net.Socket` is detached from the sender (no `'end'`/`'close'` there, server connection count decremented) unless `keepOpen`; TLS sockets are rejected with `ERR_INVALID_HANDLE_TYPE`; a received handle that lands on fd 0 is adopted; a handle that arrives right before the channel's EOF is still delivered; a send that fails after detaching closes the native socket; owned descriptors are released even when they were allocated at 0–2. `disconnect()` reports disconnected at once (later `send()` fails, a second `disconnect()` errors) but, as in Node, the close waits for the messages queued behind a handle that is still awaiting its ack — only user-initiated disconnects wait; a dead peer or exit closes immediately. - **`NODE_`-prefixed messages** (`{ cmd: "NODE_…" }`) are routed to `'internalMessage'` on both ends, as Node documents; this applies to `Bun.spawn({ ipc })` children too. - **Windows handle transfer**: sockets cross processes with `WSADuplicateSocketW` — the exported `WSAPROTOCOL_INFOW` rides along with the IPC message and the receiver imports it. Pipe and UDP shared binds report `ENOTSUP` on Windows rather than pretending to work. - **`fork()` from a parent whose stdio slot is closed** gives the child `/dev/null` for that slot (libuv's behaviour). The plain inherit action captured whatever descriptor was created next — the IPC socketpair's parent end — so the child held its own channel open and never saw `disconnect()`. - **`child_process` stdio** accepts `fs` write streams (their fd is taken from the stream's sink), and passing a stream with no descriptor gives a clear error instead of a `TODO`. - **`internal/cluster/round_robin_handle` and `internal/test/binding`** (a `udp_wrap.UDP` bind/fd shim) resolve for the vendored `--expose-internals` tests, gated exactly like `bun:internal-for-testing`. - **Stale-listen protection** (`listeningId`) so a `listen()` superseded before the primary replies closes the late handle instead of adopting it. `server.blockList` rejections under round-robin are closed silently (`'drop'` is for `maxConnections`), as in Node. ### Bun-side tests `test/js/node/cluster.test.ts` (+~1000 lines: scheduling, shared handles, unix/abstract paths, fd validation, dgram release, mid-handoff crash, early bytes, blockList, …), new `test/js/node/child_process/child_process_ipc_handle.test.ts` (handle passing semantics: detach, keepOpen, TLS rejection, fd 0, queued handles on channel close, disconnect ordering), plus additions to `child_process.test.ts`, `node-net.test.ts` and `spawn.ipc.bun-node.test.ts`. The latter previously asserted that a received `net.Socket` handle is rejected — that only held while `parseHandle` threw; it now asserts that `net.Socket` and `dgram.Socket` handles are delivered and that the descriptors are released. ### Known limitations / follow-ups - `http`/`https` server connection sockets have no transferable handle in Bun (they are native, like TLS sockets), so `child.send(msg, httpSocket)` sends the message without the handle — the same path Node takes for a handle-less socket, but Node's http sockets *do* have one; documenting or throwing like TLS is a follow-up. - A socket is converted (and detached) when `send()` is called, not when the message is actually written as in Node, so a socket queued behind an un-acked handle is not reusable if the channel dies first. A late-adopted server/dgram handle is emitted after `'disconnect'` where Node emits it before. - Cluster-internal messages are marked by wire type rather than recognised by the `NODE_` prefix on receipt, so a worker that monkey-patches `process.send` breaks the worker↔primary protocol (works in Node). - Under round-robin the `'drop'` event for `maxConnections` is emitted without Node's address payload; `server.listen({ fd })` on an fd that is already listening resolves rather than failing with `EEXIST`. - Pipe and UDP shared binds are not supported on Windows (`ENOTSUP`); the cluster tests covering them are skipped there. `cluster.schedulingPolicy` still defaults to `SCHED_RR` on Windows (Node defaults to `SCHED_NONE` there); flipping it deserves its own PR now that shared handles work. - The primary's accepted-socket pause relies on the accept callback running before the first read poll; a uSockets-level accept-paused option would make that structural. - `spawnSync` with a closed inherited stdio slot still fails with `EBADF` (pre-existing; Node aborts on the same input). --- **no test proof** · iteration 71 · Platform-specific test(s) that do not run on this machine.

Build 93382 lost linux x64-asan on lolhtml. Build 93392 (a one-file PR) lost four lanes: x64-musl and x64-android on cares, mimalloc and the WebKit tarball, freebsd aarch64 on lolhtml, windows aarch64 on cares, libuv, mimalloc and WebKit. - Those are the downloads that miss the image's prefetch cache (everything else in the same logs says `using prefetch cache`): the deps whose pins moved after the images were baked in #34782 (lolhtml #36733, mimalloc #36431, c-ares #34007, libuv #36839, WebKit several times a week), plus WebKit on every lane other than linux arm64, because `prefetch-deps.ts` only enumerates the bake host's own target (handed off separately). Each build makes on the order of a hundred live github.com downloads. - `downloadWithRetry` (`scripts/build/download.ts:156`) made 5 attempts with 2+4+8+16s of backoff, about 30s in total. The logs show agent-wide outages longer than that: on the x64-musl lane three downloads that started together failed on all five attempts over roughly two minutes, after lolhtml had succeeded on the same agent seconds earlier; on the freebsd lane lolhtml failed five times in a row while cares and mimalloc went through and WebKit succeeded on its second try. - `BuildError.format()` (`scripts/build/error.ts:33`) prints one level of cause. node's fetch throws `TypeError: fetch failed` and keeps the real error (DNS, connect timeout, reset) in `.cause`, so every one of these logs says only `cause: fetch failed`, and the retry lines say nothing about what failed. ### Fix - `downloadRetry`: 10 attempts, backoff doubling from 2s and capped at 30s, 180s of backoff in total instead of 30s. Exported as a `RetryPolicy` (optional last parameter of `downloadWithRetry`) so the test can run the production attempt count with the backoff zeroed. - 408 and 429 are retried along with 5xx and network errors. Other 4xx still fail on the first attempt and are still thrown unwrapped, which `prefetch-deps.ts` relies on to tell a 404 (variant not published) from a transient failure. - Each retry line names the failure it is retrying, e.g. `retry 2/10 in 2000ms (fetch failed: other side closed)`, and `format()` prints the whole cause chain through the new `describeError()`, so the next one of these says what the network did. - Why here: the prefetch cache goes stale by design as soon as a pin moves, and WebKit moves faster than images get rebaked (the images were rebaked on July 21 and this came back within two weeks; #30095 was an earlier rebake for the same symptom), so the live path is permanently on every build's critical path and has to outlast the outages CI actually sees. The wider window only costs time while github.com is actually down, when the lane would otherwise have failed; build-bun's step timeout is 60 minutes. - Verified with `test/internal/build-download-retry.test.ts` (`bun bd test`, 7 pass). It drives the real `downloadWithRetry` against a local server that drops connections or returns scripted statuses, checks the retry lines and `format()` output, and pins the schedule's total backoff at two minutes or more. Against the previous `download.ts`/`error.ts` the file fails at import (`downloadRetry` and `describeError` did not exist); each behavioral case is something the old loop did not do (10 attempts, 429 retried, reason on the retry line, cause chain in `format()`). - Also ran the loop under node, the runtime CI builds with, against a dropping server: retry lines read `(fetch failed: other side closed)` and the final report prints `cause: fetch failed: other side closed`. `bunx tsc -p scripts/build/tsconfig.json` reports nothing for these files. ### Background - Dep fetching: configure emits one ninja `dep_fetch` edge per vendored dep, which runs `scripts/build/fetch-cli.ts`; that calls `downloadWithRetry` on `https://github.com//archive/.tar.gz`, and `fetchPrebuilt` uses the same function for release tarballs such as WebKit. Both URL kinds start with a 302 from github.com (to codeload.github.com and objects.githubusercontent.com respectively), which is why one github.com problem takes out both kinds at once. - Prefetch cache: CI images run `scripts/prefetch-deps.ts` at bake time, storing each tarball under `/opt/bun-prefetch/by-url/`. `downloadWithRetry` looks there before touching the network, so a dep is served from the image only while its pinned URL is the one that was current at bake time; anything bumped later downloads live until the next `[publish images]` rebake. - `BuildError` is the build system's error type; `fetch-cli.ts` and `build.ts` print failures through its `format()`, which produces the `error:` / `hint:` / `cause:` lines seen in the build log. --- scripts/build/download.ts | 63 +++++-- scripts/build/error.ts | 31 +++- test/internal/build-download-retry.test.ts | 194 +++++++++++++++++++++ 3 files changed, 273 insertions(+), 15 deletions(-) create mode 100644 test/internal/build-download-retry.test.ts diff --git a/scripts/build/download.ts b/scripts/build/download.ts index 6efec8c5f9cc..acabc465cb41 100644 --- a/scripts/build/download.ts +++ b/scripts/build/download.ts @@ -8,10 +8,25 @@ * * ## Retry behavior * - * Exponential backoff (1s → 2s → 4s → 8s → cap at 30s), 5 attempts.

In the repro in the original description, 500 such signals survive `Bun.gc(true)` on main. - Under `--isolate` this pins the retired file's whole global object graph: 8 files that each leave one such signal pending climb to 8 live globals, where the other leaked-handle fixtures plateau at 1 to 3. - Cause: the GC keeps an observed timeout signal alive for as long as the signal itself says it has a timer, and only the signal's `cancelTimer()` clears that. Both paths above pulled the timer out of the heap without going through the signal, so it kept reporting a timer that could never fire. - The only remaining thing that clears it is the signal's destructor, which needs the GC to collect the signal first: a cycle. ### Fix - Every place the heap drops an `AbortSignal.timeout` timer unfired (fake-heap drain, `--isolate` swap, VM teardown, and the generation-stale exit when a stale timer comes due) now hands it back to the signal's `cancelTimer()`, which clears the flag and frees the timer. - Correct because it is the same path a firing timer already takes, and it produces the state these callers already wanted: an inert signal that never aborts and is collectable like any other. Dropped timers still never fire, and the existing `--isolate` "does not fire in next file" test still passes. - Verification: new fake-timers tests (the `useRealTimers()` and `clearAllTimers()` cases fail on main with 500 survivors) and two new `--isolate` fixtures that hit 8 live globals on main and plateau with the fix. Teardown relies on an existing worker-terminate test; the related timer and abort suites pass under ASAN. - Found while reviewing #37666; independent of it. ### Background - `AbortSignal.timeout(n)` aborts with `TimeoutError` after n ms. So that `AbortSignal.timeout(n).addEventListener("abort", cb)` works with no JS reference held, the GC keeps the wrapper alive while the signal has both a pending timer and an observer (`JSAbortSignalOwner::isReachableFromOpaqueRoots`). "Pending timer" means the C++ signal's `m_timeout` is non-null. - The native timer is a box owned by the C++ `AbortSignal` and linked as a node into bun's timer heap, with a back-pointer to the signal. Firing runs through the signal (`markAborted()` -> `cancelTimer()`), which clears `m_timeout` and frees the box; unlinking the heap node alone leaves `m_timeout` set. - bun:test fake timers hold timers in a separate fake heap that only advances on `advanceTimersByTime` and friends; `useRealTimers()` / `clearAllTimers()` empty it, and a timer emptied that way is meant to never fire. - `bun test --isolate` runs each file in a fresh global and, at the swap (and at VM teardown), cancels every timer still in either heap so a previous file's callbacks cannot run against the new global. Timers also carry a generation number so a stale one that comes due anyway is skipped.
    Original description ### What An `AbortSignal.timeout()` signal that has an abort listener (or any other observer) stays pinned in the heap for the rest of the process once its timer is dropped by `useRealTimers()` / `clearAllTimers()` or by the `bun test --isolate` file swap. Under `--isolate` that pins the retired file's whole global object graph, one global per file that leaves such a signal pending. ```ts import { heapStats } from "bun:jsc"; import { test, vi } from "bun:test"; test("repro", () => { vi.useFakeTimers(); for (let i = 0; i < 500; i++) AbortSignal.timeout(1_000_000).addEventListener("abort", () => {}); vi.useRealTimers(); Bun.gc(true); console.log(heapStats().objectTypeCounts.AbortSignal); // 500 on main; 0 (give or take a stack-conservative one) with this PR }); ``` `--isolate` variant: 8 files that each do `AbortSignal.timeout(3_600_000).addEventListener("abort", () => {})` at module scope and count `GlobalObject` cells after `Bun.gc(true)`. On main the count climbs 1, 2, ..., 8; the existing `setTimeout` / `Bun.serve` / `fs.watch` fixtures in the same describe block plateau at 1 to 3, and so does this one with the fix. ### Why `JSAbortSignalOwner::isReachableFromOpaqueRoots` keeps a timeout signal's wrapper alive while `hasActiveTimeoutTimer() && hasTimeoutObserver()`. That is what makes `AbortSignal.timeout(n).addEventListener("abort", cb)` work with no JS reference to the signal, and it is only correct for as long as the timer can actually fire. `hasActiveTimeoutTimer()` is `m_timeout != nullptr`, and `m_timeout` is only cleared by `AbortSignal::cancelTimer()` (called from `markAborted()` and `~AbortSignal()`). Two places on the Rust side took the timer away without going through the signal, so the signal kept claiming a timer it no longer had: - `FakeTimers::clear()` (`useRealTimers()`, `clearAllTimers()`) popped every node out of the fake heap and only released `TimeoutObject` pins; `AbortSignalTimeout` nodes were just dropped. - `All::cancel_all_timeout_objects` (the `--isolate` swap and VM teardown) unlinked `AbortSignalTimeout` nodes and nulled their back-pointer. After either, the timer can never fire, `m_timeout` is still set, the observer is still there, and the wrapper (plus its listeners, plus whatever they close over) is unreachable for GC until the process exits. `~AbortSignal()` is the only remaining thing that would clear `m_timeout`, and it only runs once the wrapper is collected: a cycle through the GC's reachability rule. The behavior these paths want is unchanged: a timer dropped by `useRealTimers()` never fires (same as a `setTimeout` created under fake timers, see the first test in `fake-timers.test.ts`), and `--isolate` must not fire a previous file's signal in the next file (`test/cli/test/isolation.test.ts`, "leaked AbortSignal.timeout does not fire in next file", still passes). The signal should simply end up as an inert, never-aborting signal that is collectable like any other, which is exactly the state `cancelTimer()` produces. ### How - `AbortSignal::cancelTimer()` becomes public, exposed to Rust as `WebCore__AbortSignal__cancelTimer`. - New `Timeout::discard(this)` in `src/jsc/AbortSignal.rs`: asserts the box is the one its signal owns and calls `cancelTimer()` on the signal, which clears `m_timeout` and frees the box via the existing `AbortSignal__Timeout__deinit` (which also unlinks the node if it is still in a heap). This is the same path a firing timer takes through `markAborted()`, so nothing new has to be kept in sync. - `FakeTimers::clear()` now collects `AbortSignalTimeout` nodes alongside the `TimeoutObject` pins (small `ClearedTimers` struct, released by both callers after the `FakeTimers` borrow ends, same reason `release_heap_pin` was already deferred) and discards them. - `cancel_all_timeout_objects` discards the signal timeouts instead of unlinking them and nulling `signal`; nulling is unnecessary now that the box is gone. At VM teardown this also means `~AbortSignal()` later finds `m_timeout` already cleared. - The generation-stale early return in `Timeout::run` (a timer from a retired `--isolate` file that somehow comes due) discards too, instead of leaving the same pinned state behind. In practice the swap's `cancel_all_timeout_objects` handles these first; this just makes the remaining exit consistent. ### Tests `test/js/bun/test/fake-timers/fake-timers.test.ts`, new `AbortSignal.timeout` block: - control: 500 observed signals stay alive while the fake heap holds their timers (`getTimerCount() === 500`) - `useRealTimers()` releases them; `clearAllTimers()` releases them (both fail on main with 500 survivors) - a signal the program still holds is left unaborted and usable (`AbortSignal.any`, `addEventListener`) after its fake timer is dropped - `advanceTimersByTime` still aborts the signal with `TimeoutError` `test/cli/test/isolation.test.ts`, "collects globals pinned by leaked handles": two new fixtures, an observed `AbortSignal.timeout` left pending in the real heap and one left pending in the fake heap of a file that never called `useRealTimers()` (both reach 8 live globals on main, plateau with the fix). VM teardown is covered by the existing `test/js/web/workers/worker-terminate-funnels.test.ts` (armed, observed `AbortSignal.timeout` in a terminated worker), which passes on the ASAN debug build along with `timer-gc-roots.test.ts`, `abort.test.ts`, `test-timers.test.ts`, the whole `fake-timers/` directory and `isolation.test.ts`. Also ran worker terminate x3 and `BUN_DESTRUCT_VM_ON_EXIT=1` (real and fake heap) with pending observed timeouts under ASAN by hand, clean. Found while reviewing #37666; independent of it (that PR only removes the eager cancel in `eventListenersDidChange`, and this one does not touch that function).

Repro in the original below. - Once stuck, `aborted` stays `false`, `reason` stays `undefined`, `throwIfAborted()` never throws, and listeners or `AbortSignal.any([s])` dependents added later never fire. Node and the browsers report `aborted: true` with a `TimeoutError` in every case. - Cause: the native timer was cancelled as a side effect of listener bookkeeping whenever the observer count read zero. No observers does not mean unreachable; the program still holds the signal, and the DOM spec says a timeout signal aborts for as long as it exists. - The cancel dates from #28761, when the timer held a ref on the signal and this was the only way to reclaim an unobserved signal (#28756). #35849 removed that ref, so since then the branch only freed the timer slightly before the next GC would. ### Fix - Delete the eager cancel. The timer is now stopped in exactly two places: when the signal aborts and when the signal is destroyed. The observer count itself is unchanged and still drives GC. - Why it is correct: a churned signal now ends up in the same state as one nobody ever touched (timer armed, zero observers, wrapper the only owner), which already worked. The timer never held the event loop open, so leaving it armed cannot keep a process alive. - The #28756 memory case still holds: removing the last listener leaves the wrapper collectible and GC frees the signal and timer together. That regression test still passes; measured growth was 36.0 MB before and 36.7 MB after. - Verification: new tests for the listener churn variants, `fs.watch()`, `Bun.spawn()`, re-observation after churn, and a Request whose signal wrapper was collected before the deadline. Seven fail on the unfixed build and on bun 1.4.0 and pass with the change; CI is green on every lane. `node:http2` was affected too and was checked by hand only. ### Background - `AbortSignal.timeout(ms)` must abort with a `TimeoutError` once `ms` passes, whether or not anything is listening. Bun backs it with a native timer that does not keep the event loop alive, like Node's unref'd timer. - Timeout observer count: the C++ signal counts abort listeners plus native consumers (spawn, fs.watch, http2, fetch) currently holding it. Its job is GC only: while it is nonzero, the signal's JS wrapper is kept alive so the timeout still has someone to notify. - Ownership: since #35849 the JS wrapper is the sole owner of the C++ signal, and collecting the wrapper runs the C++ destructor, which frees the timer. GC, not listener removal, is what reclaims an unobserved timeout signal. - Native consumers register an observer while they hold the signal and release it when done, so a subprocess exiting or a watcher closing dropped the count to zero through the same path as removing a JS listener. fetch and `node:fs` escaped only because of the order they release things in. - `Request` is the exception: it holds a native ref and re-wraps the signal each time `request.signal` is read, so the wrapper can be collected while the timeout is still observable. That is why the timer has to outlive the wrapper and only stop when the signal itself dies. --- **no test proof** · iteration 0 · Platform-specific test(s) that do not run on this machine.

    Original description `AbortSignal.timeout()` stops working as soon as the signal's observer count touches zero while the program still holds the signal: ```js const s = AbortSignal.timeout(50); const f = () => {}; s.addEventListener("abort", f); s.removeEventListener("abort", f); await Bun.sleep(150); console.log(s.aborted); // bun 1.4.0: false node 26.3.0: true ``` The same happens after `s.onabort = fn; s.onabort = null`, after a listener registered with `{ signal: controller.signal }` is removed by `controller.abort()`, after `await Bun.spawn({ cmd, signal: s }).exited` (the subprocess releases its native callback when the child exits), and even after `s.addEventListener("unrelated", fn)` with nothing removed at all. Once it has happened, `s.reason` stays `undefined`, `s.throwIfAborted()` never throws, and abort listeners or `AbortSignal.any([s])` dependents attached afterwards never fire. Node prints `true` with a `TimeoutError` reason for every one of these, and so do the browsers. ## Cause `AbortSignal::eventListenersDidChange()` in `src/jsc/bindings/webcore/AbortSignal.cpp` ended with ```cpp if (m_timeout && !aborted() && !hasTimeoutObserver()) cancelTimer(); ``` It runs on every listener add or remove, and `m_timeoutObserverCount` is zero for any timeout signal nobody is listening to, so the native timer was freed as a side effect of ordinary listener bookkeeping. "No observers" is not "unreachable": the program can still read `aborted`/`reason`, call `throwIfAborted()`, or hand the signal to something later, and https://dom.spec.whatwg.org/#dom-abortsignal-timeout requires the signal to abort after the timeout for as long as it exists. Listener presence only matters for GC (that is the "strong reference while it has abort listeners" clause), which `JSAbortSignalOwner::isReachableFromOpaqueRoots` already implements separately. ## Fix Delete that branch. The timer is now stopped in exactly two places: `markAborted()` (the signal aborted, by the timer or otherwise) and `~AbortSignal()` (nothing references the signal any more). A signal that went through listener churn therefore behaves exactly like one that was never touched, which already worked. Cancelling later instead, once the JS wrapper has been finalized, is not safe with the current holders either. `new Request(url, { signal })` keeps only a native ref (`Request.rs:1343`), nothing pins the signal's wrapper until `request.signal` is first read, and the getter re-wraps the C++ signal (`Request.rs:727`), so the wrapper is routinely collected while the timeout is still observable through `request.signal`; that works today and is now covered by a test. Every other native holder (FetchTasklet, Response's BodyAbortListener, Subprocess, the http2 SignalRef, node_fs ReadFile/WriteFile, fs.watch) registers an observer for as long as it holds the signal, which keeps the wrapper alive, and releases the observer and the ref in the same call, so for those the wrapper is only finalized when it holds the last ref and `~AbortSignal()` frees the timer at that moment anyway. Why this is the right fix rather than a narrower one: the cancel dates from #28761, when the timer held a ref on the signal and cancelling on the last listener removal was the only way to free an unobserved `AbortSignal.timeout()` before its deadline (#28756). #35849 removed that self-ref: the JS wrapper is the sole owner, `isReachableFromOpaqueRoots` keeps it alive only while `hasTimeoutObserver()`, and collecting the wrapper runs `~AbortSignal()` which frees the timer. With that in place the branch could only free the timer slightly earlier than the next GC would, and it is observably wrong. The observer counter itself is unchanged; it still drives GC reachability. The timer does not hold the event loop open (it never did; `AbortSignal__Timeout__create` inserts it without a ref, the same as Node's unref'd timer), so keeping it armed cannot keep a process alive. The resulting lifetime is the same as Node's: its timer is cleared when the signal aborts or when the signal is collected, and never because listeners were removed. The state this leaves a churned signal in (timer armed, observer count zero, wrapper the only owner) is already reachable on main: `releaseSourceObserverCounts()` (an `AbortSignal.any()` dependent aborting) and `decrementPendingActivityCount()` (fetch finishing) drop the count without going through `eventListenersDidChange()`, and the existing `timer-gc-roots.test.ts` case "AbortSignal.any([timeout, controller.signal]).abort releases the timeout" checks that GC alone reclaims the signals and their 600 s timers from that state. This change only routes the listener and native-callback paths into the same state. The #28756 scenario still reclaims memory: removing the last listener makes the wrapper collectible, and the next GC frees the signal and its timer together. Running that test's script under the debug build gives 36.0 MB growth without this change and 36.7 MB with it (the number is dominated by ASAN quarantine; 202 signals remain live in both cases, which are the test's 200 warm-up signals that keep a listener), and `test/regression/issue/28756.test.ts` passes. ## Verification New tests in `test/js/web/abort/abort.test.ts` (`AbortSignal.timeout() still fires after its observers go away`): the four listener-churn variants above plus `fs.watch(dir, { signal }).close()` (a native consumer releasing its callback synchronously), re-observation after churn (a listener added afterwards fires, `AbortSignal.any([signal])` aborts, `throwIfAborted()` throws `signal.reason`), and the asynchronous `Bun.spawn()` release when the child exits. A further test constructs Requests around timeout signals, checks with `heapStats()` that the signal wrappers were collected before the deadline, and then reads `request.signal.aborted`; it passes on 1.4.0 as well and pins the Request case described above. Each waits on a second timeout signal armed afterwards with a longer delay, which sits behind the signal under test in the timer heap, so the signal under test stays unobserved and the tests do not depend on wall-clock timing (the spawn case needs the child to exit before a 500 ms deadline; a shell exits in about 1 ms). The seven churn/fs.watch/spawn tests fail on the unfixed debug build (`aborted: false`, `reason: undefined`) and on bun 1.4.0, and pass with the change (repeated runs locally with `--rerun-each`; CI is green on every lane, including Windows and ASAN). Also passing with the change: `test/regression/issue/28756.test.ts`, `test/js/web/timers/timer-gc-roots.test.ts`, `test/js/web/abort/*`, `test/js/web/streams/pipeTo-signal-leak.test.ts`, `pipeTo-shutdown-gc.test.ts`, `test/js/web/fetch/fetch-tls-abortsignal-timeout.test.ts`, the abort-signal tests in `fetch-leak.test.ts`, `test/js/bun/spawn/spawn-signal.test.ts`, `test/js/node/util/test-aborted.test.ts`, the `--isolate` leaked-timeout test in `test/cli/test/isolation.test.ts`, and Node's `test-abortsignal-any.mjs`. Native consumers affected on the unfixed build, from going through each `add_listener`/`listen` site and its release order: `Bun.spawn`/`spawnSync` (`Subprocess::clear_abort_signal` drops pending activity first, then the callback), `fs.watch` (`detach()` removes the callback; closing the watcher left the signal stuck), and `node:http2` `session.request(headers, { signal })` (the stream's `SignalRef` drop; a signal reused after a stream closed never fired). spawn and fs.watch are tested; http2 was verified by hand (stuck on 1.4.0, `TimeoutError` with the fix, same as Node) and goes through the same `cleanNativeBindings()` entry point, but an http2 round trip takes over a second on a debug build, so it did not get a test of its own. A side effect of the same bug was that `spawnSync({ signal })` ignored the deadline of a signal that had lost its observers, since it reads the armed timer's deadline (`js_bun_spawn_bindings.rs`); that now works too. `fetch()`, `Response` and `node:fs` `readFile`/`writeFile` were not affected: they drop their callback before their pending-activity count (or hold only pending activity), so the counter never reached zero inside `eventListenersDidChange()`. With this change the release order of native consumers no longer matters.

The reduction in #37703 is this shape, and the ASAN use-after-free trace in #31788 is the same shape observed at runtime, in `abort_by_http_id`. - Cause: four refcount releases in `bun_http` (h2 `on_close` and `maybe_release`, `ProxyTunnel::detach_and_deref`, h3 `detach`) go through the method's `&mut self`. For the h2 and tunnel sites that release is normally the last one, so the object is freed while a reference argument to it is still live, which is UB whether or not the reference is used again. - The keep-alive guards had the same defect one step removed: they were built from the receiver, so on failure paths the free still happened inside the method, at guard drop. - Two h2 entry points, `adopt` and `abort_by_http_id`, held no ref of their own while their body could tear the session down; `adopt` then read a field of the freed session. The `adopt` case was not triggered deterministically. ### Fix - Every h2 entry point that can end with the session released now takes the pointer its holder stores (socket slot, registry, pool, or what `create` returned) and runs through one wrapper: take a guard from that pointer, run the former `&mut self` body, then release the socket ref the body gave up (recorded in a flag) and the guard's ref, both after the borrow has ended. - Property to check: inside a body no release can be the last one, because the wrapper's guard holds a ref, and the two releases that can be last run with no reference to the session in existence. The points at which refs are released relative to other work are unchanged. - Proxy tunnel: `receive` and `on_writable` build their guard from the client's handle pointer; `detach_and_deref` is deleted (`start` now builds the TLS wrapper before allocating the tunnel, and the pool fallback releases through the handle it was given); `adopt` moves the pool's handle into the client instead of re-deriving one from the receiver. - h3 `detach`'s release is never the last one (the connection's own ref outlives every stream), so it keeps `&mut self`, says why, and releases through the stream's backref. - Verification: a new source lint fails on `main` at the five receiver-release sites and passes on this branch; the existing h2, h3 and proxy suites pass on an ASAN debug build; clippy and fmt are clean. The lint is the only test that fails without the change. ### Background - Intrusive refcount: `ClientSession` and `ProxyTunnel` carry their own `ref_count`; `deref(ptr)` decrements it and frees the allocation at zero. Each holder (socket ext slot, context registry, keep-alive pool, `HTTPClient.proxy_tunnel`) owns one count, and hand-offs between holders move a count rather than bump it. - Holders of an h2 session: the TLS socket's ext slot is tagged with the session, `HTTPContext.active_h2_sessions` lists it so later requests can multiplex onto it, and the keep-alive pool holds it while it is parked with no streams. - Protectors: under both of Miri's aliasing models (Stacked Borrows and Tree Borrows), a `&mut T` argument is protected for the whole call, so freeing the pointee during the call is UB even if the argument is never touched again. This is why the fix moves the free to after the body returns instead of avoiding later uses of `self`. - `bun_ptr::ThisPtr` / `ScopedRef`: a copyable raw handle to a refcounted object, and an RAII guard that bumps on construction and releases on drop. `SessionPtr` in this PR is `ThisPtr`. - `RefPtr` (tunnels): the owning handle stored by the client or the pool; `RefPtr::deref()` releases the count that handle owns, so releasing through it is releasing through the holder's pointer.
    Original description ### Problem Four intrusive-refcount releases in `bun_http` went through the method's own receiver, `&mut self` coerced to `*mut Self` at the call: ``` src/http/h2_client/ClientSession.rs:848 on_close(&mut self) unsafe { ClientSession::deref(self) } src/http/h2_client/ClientSession.rs:959 maybe_release(&mut self) unsafe { ClientSession::deref(self) } src/http/ProxyTunnel.rs:751 detach_and_deref(&mut self) unsafe { ProxyTunnel::deref(self) } src/http/h3_client/ClientSession.rs:192 detach(&mut self, stream) unsafe { ClientSession::deref(self) } ``` (`grep -rnP '\bderef\(\s*self\s*\)' src` at 9a543cc18f; the two `SubprocessPipeReader.rs` hits are being converted in their own PR.) For the h2 and tunnel sites the release is normally the last one. An h2 session is held by the socket ext slot, the context registry and (while parked) the pool; `on_close` leaves the registry and then releases the slot's ref, and `maybe_release` does the same on a connection it cannot pool, so the session is freed inside a method that still has a `&mut self` argument pointing at it. `detach_and_deref` was reached from `HTTPContext::release_socket` with the only remaining ref to the tunnel. Freeing an allocation while a reference argument to it is live is rejected by both aliasing models regardless of whether the reference is used again (Tree Borrows, the model `bun run rust:miri` uses: "deallocation through is forbidden ... the strongly protected tag disallows deallocations", pointing at the receiver; Stacked Borrows: "deallocating while item [Unique] is strongly protected"). The reduction in #37703's description is this exact shape. The keep-alive guards had the same problem one step removed: `ClientSession::ref_scope(&mut self)` built a `ScopedRef` from the receiver and every socket event took one, so on the `fail_all` paths the free happened at the guard's drop, still inside `on_data` / `on_writable` / `resume_receive_by_http_id`; `ProxyTunnel::receive` / `on_writable` built theirs from `NonNull::from(&mut *self)`, and when delivering the bytes completes or fails the request (which releases the client's ref, or hands it to a full pool) that guard's drop is the last release. Two entry points additionally held no ref at all while their body could reach one of these releases. `adopt`: both callers in `HTTPContext::connect` (registry match and pool resume) hold nothing of their own, so when the first flush of the new stream fails, `attach` -> `fail_all` -> `on_close` freed the session and `adopt` then read `self.encoder_poisoned` from the freed allocation (needs a TLS write to fail synchronously during the adopt; I could not trigger it deterministically). `abort_by_http_id`: the ASAN trace in #31788 is this shape observed, a custom TLS context dropping re-entrantly from the aborted request's result callback, `on_close` freeing the session at its guard drop while `abort_by_http_id`'s `&mut self` was live up the stack, and the tail of `abort_by_http_id` then running on freed memory. #31788 fixes that (and two unrelated defects) by giving `abort_by_http_id` a `ref_scope()` guard of its own, which moves the free to that guard's drop, still inside the method; here every entry point gets the guard from `enter`, taken from the holder's pointer, and the free happens after the body's borrow has ended. The two PRs overlap in that one line and are otherwise independent. The h3 site is different: the per-stream ref `detach` releases is provably never the last one (the connection's ref is released only by `on_conn_close` / `fail_session`, and both drain `pending` through `detach` first), so `&mut self` is a sound receiver there. The function now says so, and releases through the pending entry's own backref so that every release in the crate goes through the pointer of the holder whose ref it is. ### Fix **h2** (`h2_client/ClientSession.rs`, `HTTPContext.rs`, `HTTPThread.rs`, `lib.rs`): every entry point that can end with the session released takes a `SessionPtr` (`bun_ptr::ThisPtr`, the pointer its holder has: socket ext tag, registry entry, pool entry, or what `create` returned) and goes through `ClientSession::enter`, which takes a guard from that pointer, runs the former `&mut self` body through a call-scoped reborrow, and after it returns releases the socket-ext ref if the body gave it up (a `socket_ref_owed` cell set by `fail_streams` and by `maybe_release`'s close branch, where the `deref(self)` calls were) and then the guard's own ref, both through the holder's pointer. Inside a body no release can be the last one (the guard holds one), and the two that can be last now run with no reference to the session in existence. Converted entries: `on_data`, `on_writable`, `on_close`, `adopt`, the leader's `attach_leader`, `enqueue`, `abort_by_http_id`, `stream_body_by_http_id`, `resume_receive_by_http_id`, `drain_response_body_by_http_id`; the bodies are private, so the type has no `&mut self` path to a release left. `ActiveSocketExt::session_mut` becomes `session() -> Option`, `HTTPThread` holds its own `ref_guard()` across the resume + drain pair (what its `ref_scope()` was for), `connect()` adopts after its registry scan has finished instead of from inside the loop that `maybe_release` swap-removes from, and the registry releases its ref through the entry it stored rather than whatever pointer the caller passed. Order of operations within each entry is unchanged; the releases happen at the same points relative to everything else, just after the body's borrow has ended. **proxy tunnel** (`ProxyTunnel.rs`, `HTTPContext.rs`, `lib.rs`): `receive` and `on_writable` take the client's handle pointer (`RefPtr::data`) and build their guard from it, the same contract the SSL callbacks in the file already use for `ref_scope`. `detach_and_deref` is deleted: `start()` now builds the SSL wrapper before allocating the tunnel, so its failure path has nothing to release, and the pool fallback in `release_socket` releases through the `RefPtr` it was handed, as `close_proxy_tunnel`, `AsyncHTTP` and the shutdown path already do. `adopt` takes the pool's `RefPtr` and moves it into the client instead of re-deriving a handle from its receiver with `RefPtr::from_raw(from_mut(&mut *self))`, so the ref the client eventually releases is the one the pool held. **h3** (`h3_client/ClientSession.rs`): `detach` documents why its release is never the last one and performs it through the stream's `session` backref. ### Test `test/internal/source-lints/self-receiver-deref.test.ts` bans `Type::deref(self)` (and the other raw-pointer release entry points of the refcount traits) and `ScopedRef` / `*RefGuard::new|adopt(self)`, checks its patterns against positive and negative spellings, and ratchets the two `SubprocessPipeReader.rs` sites at their exact count until their own conversion lands. Against `main` it reports exactly ``` src/http/h2_client/ClientSession.rs:206: SessionRefGuard::new(self) src/http/h2_client/ClientSession.rs:848: ::deref(self) src/http/h2_client/ClientSession.rs:959: ::deref(self) src/http/h3_client/ClientSession.rs:192: ::deref(self) src/http/ProxyTunnel.rs:751: ::deref(self) ``` and passes with this branch. It is deliberately limited to the bare receiver; the `ptr::from_mut(self)` family is what #37703's lint covers, and the two compose. ### Verification Debug (ASAN) build: `test/js/web/fetch/fetch-http2-client.test.ts`, `fetch-http2-adversarial.test.ts`, `fetch-http2-leak.test.ts`, `fetch-proxy-connect-tunnel-split-envelope.test.ts`, `fetch-proxy-tls-intern-race.test.ts`, `fetch-http3-client.test.ts`, `fetch-http3-adversarial.test.ts`, `fetch-http3-cold-post.test.ts`, and `test/js/bun/http/proxy.test.{ts,js}` plus the seven `proxy-stress-*` suites all pass (two `proxy.test.js` auth cases need `NO_PROXY` unset in my container because it lists `localhost`; they pass with it unset, and fail identically on the released binary with it set). `bun test test/internal/source-lints/` passes; `cargo clippy -p bun_http` and `cargo fmt --check` are clean. Not touched here, noted while reading: the pool's handle in `maybe_release` (`NonNull::from(&mut *self)`) and the h2 `Stream`/h3 `Stream` backrefs are still pointers derived from a receiver, but none of them is a release site, and the re-entrant `HTTPContext` borrows described on `unregister_h2_raw` are a separate problem.

Fixes #35420 Fixes #10915 Fixes #8501 Fixes #28284 Fixes #11348 When several git dependencies point at different branches of one repository (`git+ssh://host/repo.git#branch-a`, `...#branch-b`, ...), they share a single git-clone task whose callback queue holds one entry per dependency. Three bugs around that sharing, all reproducible locally with a bare repo (no network): ## Bug 1: install from a complete lockfile on a cold cache silently skips packages `bun install --frozen-lockfile` with a cold cache installed only one of N git deps sharing a repo, printed `N packages installed`, and exited 0. Re-running recovered roughly one package per attempt (`error: InstallFailed cloning repository`). Cause: in the hoisted installer, the clone-completion handler in `runTasks.rs` only processed `clone.dep_id`, the single dependency stored on the task, and enqueued one checkout. Every other dependency queued on the shared clone was dropped on the floor. Fix: drain the clone task's whole callback queue and enqueue a checkout per waiting dependency (deduped by checkout id). ## Bug 2: resolve phase fails with `failed to resolve` for specs that appear both directly and transitively With no lockfile, a project whose git deps are also re-declared by one of the packages (same URL + committish strings) deterministically errored with `error: @git+... failed to resolve` for a varying subset of the duplicated specs. Cause: a git checkout's callback queue is drained exactly once, when its completion is processed. A duplicate dependency enqueued after that drain (checkout completions for siblings land in the same task batch, before the deferred dependency-list flush runs) pushed a callback nothing would ever process, so its resolution slot stayed invalid. The in-memory fast path could not catch it because first-time git deps hash an empty `package_name`. Fix: record which package each completed checkout appended (`git_checkout_packages` map) and resolve late arrivals against it directly, applying the same `resolved`/`package_name` fix-up the drain applies. ## Bug 2b: the same parked-callback bug in the tarball extract path The mechanism behind bug 2 is not git-specific. `github:` and tarball-URL dependencies that appear both directly and transitively park the late dependency on an already-drained extract task the same way (#8501, #10915, #28284). Reproduced locally with tarball URLs (16 packages, one re-declaring 11 siblings: `failed to resolve` in 4 of 5 runs) and with the #8501 repro (`bun add github:angular/cli-builds#21fd54b0...` fails on canary with `error: @angular-devkit/core@github:angular/angular-devkit-core-builds#910531a failed to resolve`, installs all 230 packages with this change). Fix: the completed-checkout map generalizes to every extract task that appends a package; the github and tarball enqueue arms consult it like the git arm does. ## Bug 3: `git+file://` dependencies never clone `dependency.rs` accepts `git+file:` as a git dependency, but the clone task recognized neither an https nor an ssh URL and finished without running git, with `Status::Waiting` and zeroed task data that the main thread treated as a successful clone. The zeroed fd then poisoned `git_repositories`, so every later dependency on that repo ran `git log` against a nonexistent directory (`fatal: cannot change to '.../.git'`). Fixes: clone with the URL as written when neither matcher recognizes it (git supports `file://` and `git://` natively), and only insert the repo fd into `git_repositories` on clone success so a failed clone can be retried instead of poisoning the map. ### How did you verify your code works? `test/cli/install/bun-install-git-deps.test.ts` (new): a local bare repo with orphan branches, served over git's dumb HTTP protocol by `Bun.serve` (`git update-server-info` + static files), so no network is involved. - fresh resolve with 16 branches of one repo where one branch re-declares 11 siblings: previously `failed to resolve`, now all 16 install - the same direct+transitive shape with tarball-URL dependencies (static `.tgz` files served by `Bun.serve`): previously `failed to resolve`, now all 16 install - the #8501 shape with `github:` specifiers (a single `github:` direct dependency whose own `github:` dependencies overlap, via `GITHUB_API_URL` pointed at a local `Bun.serve`): previously `error: @scope/pkg-b@github:scope/pkg-b#v1 failed to resolve`, now all 17 install - install from a complete lockfile on a cold cache with 2 branches of one repo: previously 1 of 2 installed with exit 0, now both install - `git+file://` dependency: previously `error: no commit matching ... (but repository exists)`, now installs All five tests fail on bun 1.4.0-canary and on an unfixed debug build, and pass with this change (hoisted and isolated linkers both verified manually for the 16-branch scenario). The real-world #8501 repro (`bun add github:angular/cli-builds#21fd54b0...`) was also verified directly: canary fails with `error: @angular-devkit/core@github:angular/angular-devkit-core-builds#910531a failed to resolve`, this change installs all 230 packages. --- **[review]** gate passed · iteration 4 · 5 files touched

Each item below is a small, self-contained behavior change with a regression test in the existing test file for that module. No API is removed. ## Behavior notes, by area **install** - Symlink entries in GitHub/git tarballs are written after every file and directory entry (both the streaming and buffered extractors share one implementation), so no later entry is ever created through an archive-provided link; the created tree for well-formed archives is unchanged. - The streaming extractor keeps its input buffer alive until libarchive has finished with it, including when the tar reader retries past a damaged header block; the end-of-body hand-off between the HTTP thread and the extraction worker happens under the stream lock. - `workspace:` specifiers are only honored in the root and workspace manifests; a `workspace:` range inside a downloaded package resolves like any other unresolvable range. - The on-disk and in-memory manifest caches check the stored package name on load, not just the name hash. - `--trust ` applies to the packages actually resolved in that package's dependency tree, and the names written to `trustedDependencies` are the same identity `bun install` checks on later runs. - Git dependencies: a top-level `node_modules` symlink in the checkout is not carried into `node_modules//`, and `.bun-tag` is written without following an existing entry. Committed `node_modules` directories (bundleDependencies) are untouched. - `bun install --verbose` masks `Authorization`/`Proxy-Authorization` header values and credential-bearing URLs in request logs; bunfig `password` values are redacted in config diagnostics. **shell** - Cross-device `mv` opens the source without following a swapped-in link and takes ownership/mode from the opened descriptor. - `$${value}`: an interpolated value directly after a literal `$` is always passed as data, never joined into a variable name. - Readers and captured writers stay alive for the whole I/O callback that references them, including when a builtin finishes synchronously on a write error (`cat > /dev/full`, closed pipes). - `bun run --shell=system` on Windows rejects pass-through arguments that `cmd.exe` would reinterpret. **TLS / node:tls / node:quic** - A TLS 1.3 session resumed by a client that never presented a certificate reports `authorized === false` (node:tls, node:https, `Bun.listen`), same as its original handshake. - `node:quic`: with the default `verifyPeer`, a client whose server certificate does not validate refuses natively before any queued stream data is sent and before peer streams/datagrams are delivered; `session.opened` rejects with the same error as before. Servers with `verifyClient: true` require a client certificate during the handshake. - `tls.connect({ socket, host: })` checks the certificate against that IP; `Bun.connect` over `unix:`/`fd:` with `tls` checks against `serverName` or `localhost`. - `Http2SecureServer` connections injected via `emit('connection')` use the server's full TLS option set (min/max version, ciphers, crl). - `delete process.env.NODE_TLS_REJECT_UNAUTHORIZED` restores the default and later assignments still take effect. **Bun.serve / HTTP/3** - HTTP/3 requests whose header names or values contain CR, LF or NUL are rejected as malformed, matching the HTTP/1.1 parser; `:authority` goes through the same host validation as `Host`. - With `http3: true`, `tls.requestCert`/`rejectUnauthorized` are enforced on QUIC connections as they are on TCP. - Linux directory routes keep using `openat2` resolution after an unrelated `EPERM`/`EINVAL`. **fetch / HTTP client** - Very large file-backed request bodies send the correct `Content-Length`. **SQL** - MySQL: result rows larger than one wire packet (16 MiB) are reassembled before decoding. - MySQL/Postgres URL and option parsing: `?ssl=`, `?ssl-mode=`/`sslmode=` spellings and `ssl: "verify-full"`-style strings select the corresponding `sslmode`; `tls: { caFile }` enables verification like `ca` does; an explicit option object still wins over the URL. - Postgres: an error response for a simple query only detaches that query's own statement. - Duplicate column names that differ only in invalid UTF-8 bytes no longer share one property slot. **crypto** - `Bun.SHA*`/`MD5` `update()` and `Bun.CryptoHasher.hash()` coerce every argument before touching hasher state. - Ed25519 sign checks that the supplied public half matches the private key. **runtime / bundler / misc** - `Buffer.write`/`fill`/`TextEncoder.encodeInto` with a string ending in a lone high surrogate size the fast path from the full input. - Workers read `process.env` at runtime like the main thread instead of inlining values at transpile time. - `module.enableCompileCache()` only uses a cache directory owned by the current user with private permissions. - Windows `bun:ffi` `cc()` creates a fresh private compiler-runtime header directory per process. - `zlib` `params()` resets stream pointers before `deflateParams`; `BundlerPlugin` native filter registration type-checks its arguments; destructuring a macro result with repeated keys and nested macro evaluation keep the AST store consistent. - `bun publish` launches the browser opener by absolute path. ## Tests 93 new regression tests across 39 existing test files; each fails on the current release and passes on this branch (three are platform-gated: Windows `--shell=system`, non-ASAN `cc()`, and macOS-only extractor assertions run in reduced form elsewhere). `cargo clippy --workspace`, `bun run rust:check-all` (10/10 targets), oxlint and prettier are clean. ## Related Larger items from the same pass are in their own PRs: #37590 (security scanner receives every resolution) and follow-ups for install-cache entry identity, off-thread I/O into WebAssembly memory, and TLS common-name fallback parity with Node.js. --- packages/bun-types/sql.d.ts | 27 ++- packages/bun-usockets/src/crypto/openssl.c | 16 +- packages/bun-usockets/src/libusockets.h | 1 + packages/bun-usockets/src/quic.c | 51 ++++- src/ast/lib.rs | 18 +- src/bun_core/fmt.rs | 4 +- src/bun_core/lib.rs | 3 + src/bun_core/string/immutable/unicode.rs | 10 +- src/http/AsyncHTTP.rs | 2 +- src/http/lib.rs | 38 ++-- src/install/PackageInstaller.rs | 36 ++-- .../PackageManager/PackageManagerEnqueue.rs | 124 ++++++------ .../PackageManager/PackageManagerLifecycle.rs | 64 +++---- .../PackageManagerResolution.rs | 7 +- src/install/PackageManifestMap.rs | 23 ++- src/install/TarballStream.rs | 180 +++++------------- src/install/isolated_install.rs | 17 +- src/install/isolated_install/Installer.rs | 30 +-- src/install/lockfile.rs | 6 +- src/install/lockfile/Package.rs | 2 +- src/install/npm.rs | 5 +- src/install/repository.rs | 31 +-- src/install_types/resolver_hooks.rs | 4 + src/io/PipeReader.rs | 26 ++- src/io/lib.rs | 20 ++ src/js/builtins/ProcessObjectInternals.ts | 9 +- src/js/internal/sql/shared.ts | 34 +++- src/js/node/_http2_upgrade.ts | 7 +- src/js/node/net.ts | 3 +- src/js/node/tls.ts | 20 +- src/js_parser/visit/mod.rs | 15 +- src/jsc/NodeCompileCache.rs | 32 +++- src/jsc/bindings/JSBundlerPlugin.cpp | 18 +- src/jsc/bindings/JSEnvironmentVariableMap.cpp | 54 ++++-- src/jsc/bindings/webcrypto/CryptoKeyOKP.cpp | 25 +-- .../webcrypto/CryptoKeyOKPOpenSSL.cpp | 3 +- src/jsc/web_worker.rs | 2 + src/libarchive/lib.rs | 167 ++++++++-------- src/runtime/cli/publish_command.rs | 11 +- src/runtime/cli/run_command.rs | 11 ++ src/runtime/crypto/CryptoHasher.rs | 24 +-- src/runtime/ffi/ffi_body.rs | 104 +++++----- src/runtime/node/quic/session.rs | 53 +++++- src/runtime/node/zlib/NativeZlib.rs | 13 +- src/runtime/server/server_body.rs | 22 ++- src/runtime/shell/IOReader.rs | 22 ++- src/runtime/shell/builtin/mv.rs | 36 +++- src/runtime/shell/shell_body.rs | 21 +- src/runtime/shell/subproc.rs | 11 +- src/runtime/socket/socket_body.rs | 28 +-- src/runtime/webcore/Request.rs | 2 +- src/simdutf_sys/simdutf.rs | 18 -- src/sql/mysql/protocol/PacketHeader.rs | 2 +- src/sql/shared/ColumnIdentifier.rs | 7 +- src/sql_jsc/mysql/MySQLConnection.rs | 63 ++++++ src/sql_jsc/postgres/PostgresSQLConnection.rs | 20 +- src/sys/lib.rs | 22 ++- test/bundler/bundler_plugin.test.ts | 56 +++++- test/bundler/transpiler/macro-test.test.ts | 23 +++ test/bundler/transpiler/transpiler.test.js | 52 +++++ .../bun-install-lifecycle-scripts.test.ts | 62 ++++++ test/cli/install/bun-install-registry.test.ts | 84 ++++++++ .../bun-install-streaming-extract.test.ts | 60 ++++++ test/cli/install/bun-install.test.ts | 145 +++++++++++++- test/cli/install/bun-publish.test.ts | 94 ++++++++- test/cli/install/bun-run.test.ts | 51 +++++ test/cli/install/bun-workspaces.test.ts | 66 +++++++ test/cli/install/redacted-config-logs.test.ts | 47 +++++ .../install/symlink-path-traversal.test.ts | 132 ++++++++++++- test/js/bun/ffi/cc.test.ts | 63 ++++-- .../bun/http/serve-directory-routes.test.ts | 61 +++++- test/js/bun/http/serve-http3.test.ts | 150 ++++++++++++++- test/js/bun/net/socket.test.ts | 145 +++++++++++++- test/js/bun/shell/bunshell.test.ts | 24 +++ test/js/bun/shell/commands/mv.test.ts | 25 +++ .../bun/shell/shell-pipe-read-fault.test.ts | 84 +++++++- test/js/bun/shell/yield.test.ts | 39 ++++ test/js/bun/util/bun-cryptohasher.test.ts | 69 +++++++ test/js/node/buffer.test.js | 51 +++++ .../js/node/http2/node-http2-upgrade.test.mts | 48 +++++ .../js/node/module/node-module-module.test.js | 98 ++++++++++ test/js/node/quic/quic-sni.test.ts | 80 ++++++++ test/js/node/quic/quic-stream.test.ts | 52 +++++ ...-tls-connect-hostname-verification.test.ts | 102 +++++++++- test/js/node/tls/node-tls-server.test.ts | 113 +++++++++++ .../worker_threads/worker_threads.test.ts | 40 ++++ .../zlib/zlib-handle-bounds-check.test.ts | 21 ++ .../js/sql/adapter-env-var-precedence.test.ts | 173 +++++++++++++++++ test/js/sql/postgres-datarow-overrun.test.ts | 30 +++ .../sql/postgres-error-then-datarow.test.ts | 89 +++++++++ test/js/sql/sql-mysql.test.ts | 106 +++++++++++ test/js/web/crypto/web-crypto.test.ts | 54 ++++++ test/js/web/fetch/fetch.test.ts | 89 ++++++++- test/js/web/fetch/fetch.tls.test.ts | 65 +++++++ test/js/web/workers/worker.test.ts | 35 ++++ 95 files changed, 3741 insertions(+), 661 deletions(-) diff --git a/packages/bun-types/sql.d.ts b/packages/bun-types/sql.d.ts index b6d524b0cbba..3e52469654a9 100644 --- a/packages/bun-types/sql.d.ts +++ b/packages/bun-types/sql.d.ts @@ -323,17 +323,38 @@ declare module "bun" { max_lifetime?: number | undefined; /** - * Whether to use TLS/SSL for the connection + * Whether to use TLS/SSL for the connection.

This is a refactor of how bun's HTTP/2 engine tracks an inbound header block that is still being assembled across CONTINUATION frames. - That state was eight loose fields on the connection, with 0 doubling as "nothing in flight" and "not a push", and two flags (stream closed, stream refused) that are meant to be mutually exclusive but nothing enforced it. - Each opener wrote all eight fields and the finisher read them back off the connection and reset some by hand, so a completed block could observe values left over from an earlier block. ### Fix - The eight fields become one `Option` holding the stream the next CONTINUATION must arrive on plus a metadata record: the target stream, an optional push parent, flags, and a three-way disposition (deliver, stream closed, refused). The `None` fits in a niche, so the connection gets no bigger. - HEADERS and PUSH_PROMISE each build that record and share one tail that either finishes the block or parks it; the finisher takes the record as an argument instead of reading the connection, so there is nothing to reset and "closed and refused at once" cannot be expressed. - Behavior is intended to be unchanged: the "unexpected CONTINUATION frame" GOAWAY moves into the CONTINUATION handler with the same error code and message, and the one non-mechanical change (trailer detection also excludes refused blocks) is equal because a refused block never has a stream entry. - Verification: no new test. `cargo check` and clippy are clean, a debug build succeeds, and the existing http2 tests pass (418 pass, 6 skip, 0 fail). ### Background - An HTTP/2 header block starts in a HEADERS or PUSH_PROMISE frame and may continue in CONTINUATION frames. Until a frame with END_HEADERS arrives, the only legal next frame on the connection is a CONTINUATION for that same stream (RFC 9113 sections 4.3 and 6.10). - HPACK state is shared by the whole connection, so a block must be decoded in full even when bun is going to reset the stream (it was already closed, or the embedder refused it). The disposition only decides what happens after decoding. - PUSH_PROMISE is sent on the parent stream but its header block belongs to the promised stream, so the CONTINUATIONs arrive on the parent while the block's target is the promised id. - `Option` is stored as a plain 4-byte integer with 0 meaning `None`. Stream 0 is already rejected as a push parent, so this is the old encoding with the meaning in the type.
    Original description ## What `Connection` in `src/runtime/api/bun/h2/connection.rs` described the inbound header block it was assembling with eight loose fields: `continuation_stream: u32` (0 meaning "not assembling"), `header_target`, `header_push_parent: u32` (0 meaning a plain HEADERS block), `header_flags`, `header_end_stream`, `header_is_request`, and the mutually exclusive `header_stream_closed` / `header_stream_refused`. `handle_headers` and `handle_push_promise` each wrote all of them as a block, `new()` zeroed them, and `finish_header_block` read them back off `self`, reset `continuation_stream` and `mem::take`'d the two bools. They are replaced by ```rust struct HeaderBlockInFlight { /// The stream id the next frame MUST be a CONTINUATION for (the parent stream id while /// assembling a PUSH_PROMISE block). continuation_stream: u32, meta: HeaderBlockMeta, } struct HeaderBlockMeta { target: u32, push_parent: Option, flags: u8, end_stream: bool, is_request: bool, disposition: BlockDisposition, } #[derive(Clone, Copy, PartialEq, Eq)] enum BlockDisposition { Deliver, StreamClosed, Refused } ``` and a single `header_block_in_flight: Option` field next to the existing `data_in_flight: Option`, which already had this shape. The 2 opening handlers each build one `HeaderBlockMeta` literal and hand it to a small shared tail, `finish_or_park_header_block`, which either calls `finish_header_block(sink, &meta)` (END_HEADERS set) or parks it as `Some(HeaderBlockInFlight { continuation_stream: hdr.stream_id, meta })`; for PUSH_PROMISE that is the parent stream while `meta.target` is the promised id, exactly as before. `finish_header_block` now takes `&HeaderBlockMeta` and destructures it, so its `continuation_stream = 0` store and the two `mem::take` calls are gone, and its two `if stream_refused` / `if stream_closed` early returns become one exhaustive `match disposition`. The 3 remaining readers change one line each: the streamed-DATA condition in `receive()` and the "expected CONTINUATION" guard in `dispatch()` test the `Option`, and `handle_continuation` begins with `let Some(inflight) = self.header_block_in_flight.take() else { GOAWAY }`, which is the RFC 9113 §6.10 "unexpected CONTINUATION" check that previously sat in `dispatch()` immediately before the frame-type match (same position in the frame's processing, same error code and debug string); a non-final CONTINUATION puts `inflight` back, the final one finishes with `&inflight.meta`. The one non-mechanical translation is `is_trailer`, which now requires `disposition == Deliver` where it previously only excluded the closed case; a refused block never has a `streams` entry, so the value is the same. `header_block: Vec` deliberately stays outside the `Option`, since `finish_header_block` reuses its capacity across blocks. One file, +143/-108 lines (about half of that is docs moving onto the new types and the re-indented `match`). ## Why The type now states what the field comments used to: there is either no block in flight or exactly one, with the stream its CONTINUATION frames must arrive on; a block either came in a PUSH_PROMISE (`Some(parent)`) or did not; and a completed block has exactly one of three dispositions, so "closed and refused at once" is unrepresentable and `finish_header_block` can no longer observe state left over from a previous block. It is zero-cost: `Option` is 16 bytes (the `None` lives in the bool/enum niche) where the eight fields occupied 17 bytes of `Connection`, `Option` is the same 4 bytes as the `u32` it replaces and `NonZeroU32::new(hdr.stream_id)` stores the same value with the same 0-means-none encoding (stream 0 is already rejected by `wire::validate_header`), the per-frame "assembling?" tests are still one compare each, the §6.10 check runs exactly as often as before, and the block bytes still go through the same reused `Vec`. Part of a series of small type-system hardening changes; each PR stands alone. ## Verification `cargo check` and `cargo clippy` are clean for the touched crates. Debug build succeeds. `bun bd test test/js/node/http2/h2-conformance.test.ts test/js/node/http2/node-http2-continuation.test.ts test/js/node/http2/h2-push-refusal-staged.test.ts test/js/node/http2/node-http2.test.js`: 418 pass, 6 skip, 0 fail (424 tests across 4 files).

The record transpose_require created for require("bindings") is retargeted at the addon instead of being left unused; a leftover unused record is un-deferred and resolved again when the module is reached through require() or import(), which bundled the bindings package after all. The addon lookup moves into the resolver and follows bindings' getRoot() (nearest package.json, named or not, or node_modules directory), the file name carries the .node extension from the parser on, and a missing addon is reported through the regular unresolved-record path so a call inside try/catch throws at runtime. Tests move to bundler_loader.test.ts and cover both targets, both argument forms, other options, computed names, a Debug build directory without bindings installed, both module-root rules, an addon named like a builtin, the missing-addon error and try/catch fallback, external and packages=external, the browser target, and the dev server format. --- docs/bundler/executables.mdx | 2 + src/ast/import_record.rs | 4 +- src/bundler/ParseTask.rs | 8 ++ src/bundler/bundle_v2.rs | 166 ++++++++------------------ src/js_parser/p.rs | 74 ++++++++++++ src/js_parser/parse/parse_entry.rs | 1 + src/js_parser/parser.rs | 7 ++ src/js_parser/visit/visit_expr.rs | 52 ++------ src/resolver/resolver.rs | 57 ++++++++- test/bundler/bundler_compile.test.ts | 124 +------------------ test/bundler/bundler_loader.test.ts | 172 ++++++++++++++++++++++++++- test/napi/napi.test.ts | 12 +- 12 files changed, 389 insertions(+), 290 deletions(-) diff --git a/docs/bundler/executables.mdx b/docs/bundler/executables.mdx index 77cb6a6ba3c4..dc074a0be6ed 100644 --- a/docs/bundler/executables.mdx +++ b/docs/bundler/executables.mdx @@ -835,6 +835,8 @@ const addon = require("./addon.node"); console.log(addon.hello()); ``` +Packages that load their addon with `require("bindings")("name")` (or `require("bindings")({ bindings: "name" })`) are handled as well: at build time Bun looks for the `.node` file in the directories the `bindings` package would search (`build/Release`, `build/Debug`, ...) under the package's root and embeds it.

    Release notes

    Sourced from actions/github-script's releases.

    v9.0.0

    New features:

    • getOctokit factory function — Available directly in the script context. Create additional authenticated Octokit clients with different tokens for multi-token workflows, GitHub App tokens, and cross-org access. See Creating additional clients with getOctokit for details and examples.
    • Orchestration ID in user-agent — The ACTIONS_ORCHESTRATION_ID environment variable is automatically appended to the user-agent string for request tracing.

    Breaking changes:

    • require('@actions/github') no longer works in scripts. The upgrade to @actions/github v9 (ESM-only) means require('@actions/github') will fail at runtime. If you previously used patterns like const { getOctokit } = require('@actions/github') to create secondary clients, use the new injected getOctokit function instead — it's available directly in the script context with no imports needed.
    • getOctokit is now an injected function parameter. Scripts that declare const getOctokit = ... or let getOctokit = ... will get a SyntaxError because JavaScript does not allow const/let redeclaration of function parameters. Use the injected getOctokit directly, or use var getOctokit = ... if you need to redeclare it.
    • If your script accesses other @actions/github internals beyond the standard github/octokit client, you may need to update those references for v9 compatibility.
