node:http: keep the body of a paused Upgrade request and resume reads at the switch to tunnel mode by robobun · Pull Request #43579 · oven-sh/bun

robobun · 2026-09-19T21:30:30Z

Problem

An Upgrade request carries its body in the same read as its head. The 'upgrade' listener calls req.pause(), reads the socket, and calls req.resume() later. The body and 'end' never arrive. If the socket is read later, no byte after the body arrives. Node v26.3.0 delivers both.
A read of the socket calls req.resume(), also on a paused request (#resumeSocket, src/js/node/_http_server.ts:1779). The listener runs before the rest of its read is parsed, so the body flows away with no listener.
The switch to tunnel mode at the end of the body (packages/bun-uws/src/HttpContext.h:620) leaves the socket paused. In tunnel mode resume() on the response does nothing (src/runtime/server/NodeHTTPResponse.rs:524).

Fix

A paused request is resumed one event loop turn after the read, and only if its body is still incomplete (Node: UpgradeStream._read until requestBodyCompleted()). Other requests are resumed at once.
The switch to tunnel mode calls Bun__NodeHTTP__onReadsResumable, the hook that onWritable uses. It keeps the flood prevention pause while response bytes are unsent.
Verified: test/js/node/http/node-http-req-socket-pause.test.ts. 3 new tests fail on main, 2 with either half of the fix alone. 2 more pin the resumes that stay.
Self-reviewed: 3 concerns raised, 3 addressed (Notes).

Background

Upgrade with a body: the body goes to req, the bytes after it to the listener's socket. A read of that socket resumes the request, so an unread body cannot block it.
Tunnel mode (isConnectRequest): the parser passes all later bytes to the JS socket unparsed.
req.pause(), or a full request buffer, pauses reads of the connection.

Notes

Repro. One write carries the head and a 100 byte body. The listener calls req.pause() and socket.on("data"). The client then sends ping-1;. Later the server calls req.on("data"), req.on("end") and req.resume(), and the client sends ping-2;.

	result
Node v26.3.0	`ping-1;`, then 100 body bytes and `'end'`, then `ping-2;`
main	`ping-1;`, `ping-2;`. The body and `'end'` never arrive. `req.readableFlowing` is `true`
main, socket read after the listener	nothing arrives on the socket, and the body is lost
this branch	same as Node in both cases

The same holds on a kept-alive connection, with socket.pipe(), with on("readable") and read(), with a synchronous socket.read() in the listener, and over TLS.

Why one event loop turn, and not process.nextTick. The native dispatch drains microtasks and the tick queue before it returns to the parser (src/runtime/server/mod.rs:1382). A tick that the listener queues runs before the rest of the read is parsed. setImmediate runs after the read callback. Node emits 'upgrade' after parser.execute() consumed the whole read. With a complete body it hands over the raw socket, and nothing resumes the request.

The three concerns from the self-review, and the two tests that pin them.

The first version applied Node's rule ("resume only while the body is incomplete") to every request. It broke a listener that is correct under Node: if (req.complete) accept(); else req.once("end", accept); with a read of the socket and no reader of the body. Inside the listener req.complete is still false in Bun when the body came with the head (Node has true), so that listener waits for 'end', and it gets there only because the read of the socket resumes the request. A request that is not paused is resumed at once again, as on main. node:http: slice 'upgrade' head to the post-body remainder and close on unsatisfied-body FIN #35983 is about req.complete inside the listener.
The second version never resumed a paused request. A listener that pauses the request and never resumes it then held the socket behind a body larger than the highWaterMark. Node and main resume that request and the socket gets its bytes. The deferred check keeps this.
wss.handleUpgrade() from the request's 'end' listener runs inside the body callback of the last chunk. upgrade() adopts the socket in place, and its ext holds a WebSocketData from then on. The new native call skips a socket that was upgraded this way. It tells by the kind of the socket (us_socket_kind(user) == socketKind()), because upgradedWebSocket is per context and another connection's upgrade() in the same drain overwrites it (from the review on this PR).

Differences from Node that remain.

A request that is not paused, the body came with the head, the socket is read, and the body is read later: Node keeps the body. Bun resumes the request (main and this branch), so the body is gone. This needs req.complete at 'upgrade'.
A paused request whose body arrives in a later read, and the socket is read after that: Node keeps the body, because its parser received it before the read of the socket. In Bun req.pause() stops the reads, so the body is still in the kernel, and the read of the socket resumes the request like UpgradeStream._read. Same as main. If the socket is read before the body arrives, Node loses the body too.
req.complete is false and head is empty inside the listener when the body came with the head.
A tunnel has no read backpressure. That is the same for every CONNECT and Upgrade tunnel on main.

The third test and Node. A chunked body larger than the highWaterMark arrives with the head, so the first chunk pauses the connection and the end of the body arrives while it is paused. Node v26.3.0 delivers the body, but its socket never reads again (socket._handle.reading stays false after parserOnBody stops it). Bun delivers the later bytes. The other four tests give the same events under Node v26.3.0 (checked with standalone scripts).

Each half is needed. With only the _http_server.ts change, the second and third test time out: no tunnel byte arrives. With only the HttpContext.h change, the first and second test fail on req.readableFlowing. On main the first two tests fail at once on req.readableFlowing, and the third by the test timeout: a lost tunnel byte produces no event.

Why the native call is safe there. It runs after the body callback, and after the closed and shut down checks. us_socket_resume can close a socket whose poll cannot be re-armed, so the handler returns nullptr then, like the other close paths. The queue of parked pipelined requests is always empty at this switch: an accepted Upgrade is never pipelined, and after its dispatch the parser never reaches a request boundary again. resume() re-arms a timeout of 0 for node:http (idleTimeout: 0).

Regression check against main. A script matrix ran each combination under main, this branch and Node: 17 ways to consume the request (none, 'data', 'end' only, req.complete or 'end', 'readable', for await, pipe(), Readable.toWeb(), three pause patterns, and slow or late variants), the socket read in the listener, after it, late, synchronously, through pipe() or never, the body with the head, in a later write, in two parts or in 8 pieces, 100 bytes and 5000 bytes with a 1 KiB highWaterMark, Content-Length and chunked. 408 combinations: no result is worse than main. Every difference is a request with readableFlowing === false (paused, or read through 'readable') that now gets its body, or a socket that now gets its bytes.

Suites run with the debug build. node-http-req-socket-pause.test.ts, node-http.test.ts, node-http-with-ws.test.ts, node-http-backpressure.test.ts, node-http-server-timeouts.test.ts, node-http-server-abort-events.test.ts, node-http-server-socket-end-drain.test.ts, test/js/first_party/ws/ws.test.ts, and from test/js/node/test/parallel: test-http-upgrade-* (14 files), test-http-parser-freed-before-upgrade.js, test-http-server-request-timeout-upgrade.js. All pass. In node-http-connect.test.ts, tests should run on bun passes its 5 s limit under the debug build: its sub-suite passes (7 of 7) and takes 6.7 s there. All other tests of that file pass.

Found during the review of #43376. That PR resumes reads at the immediate switch to tunnel mode (upgradeToTunnelModeImpl). This PR does the same at the switch at the end of the body. The two diffs do not touch the same lines.

Found next to this, not fixed here.

On a kept-alive connection a socket.write() from the 'upgrade' listener does not reach the client until socket.end(). node:http: don't leave the server socket Duplex corked across kept-alive requests #35664 covers it.
After upgrade() from the body callback, the data handler keeps going on the adopted socket (inStream = nullptr, parser state). node:http: keep parsing other connections after an upgrade from a request body handler #43182 covers it.
The branch of #resumeSocket for requests that are not upgrades reads handle.hasBody (src/js/node/_http_server.ts:1802). The socket handle has no such property, so emitServerSocketEOFNT never runs. To make it live changes every request whose handler reads req.socket after a paused body, so it needs its own change.
A pipe() that pauses the request between the read of the socket and the deferred check sees one write() above its highWaterMark. No byte is lost. Node's UpgradeStream._read overrides a pause the same way.

… at the switch to tunnel mode A read of the upgrade socket resumed the request at once, also one that its 'upgrade' listener paused. The listener runs before the rest of its read is parsed, so a body that arrived with the head then flowed away with no listener. A paused request is now resumed one event loop turn later, and only if its body is still incomplete then, like Node.js's UpgradeStream. A request that is not paused is resumed as before. The switch to tunnel mode at the end of the body now resumes reads that req.pause() or a full request buffer paused. pause() and resume() on the response do nothing in tunnel mode, so the socket stayed paused and later tunnel bytes never arrived.

Walkthrough

The change updates Node HTTP upgrade handling to resume paused request-body reads safely before tunnel processing. It adds deferred resumption logic and native socket checks, with tests for body completion, incomplete bodies, listener timing, and tunnel data.

Changes

Upgrade request resumption

Layer / File(s)	Summary
Deferred upgrade resumption `src/js/node/_http_server.ts`	Paused upgrade requests defer resumption until native body reading completes. Flowing requests resume immediately.
Native tunnel transition `packages/bun-uws/src/HttpContext.h`	Native handling verifies the socket kind, resumes resumable reads, and stops when resumption closes the socket.
Upgrade resumption validation `test/js/node/http/node-http-req-socket-pause.test.ts`	Tests cover paused and unpaused bodies, listener timing, incomplete bodies, request completion, and subsequent tunnel bytes.

Status: ready for review.

How I reproduced it. A node:http server has an 'upgrade' listener that calls req.pause() and reads the socket. A net client sends an Upgrade request with a 100 byte body in one write, then ping-1;. The server calls req.resume() later.

Node v26.3.0: the request gets its 100 bytes and 'end'.
Bun 1.4.3-canary (367d939): the request gets neither. If the listener reads the socket later, the bytes after the body never arrive.
This branch: same as Node.

The new tests in test/js/node/http/node-http-req-socket-pause.test.ts cover both symptoms. Three of them fail on main.

Findings marked 🟡 are optional suggestions and need no follow-up push.

Additional findings (outside the current diff — GitHub can't attach inline comments there):

🟣 src/js/node/_http_server.ts — nit: the sibling of the new check is still broken: src/js/node/_http_server.ts:1805 reads handle.hasBody on JSNodeHTTPServerSocket, which has no such property, so bodyReadState is undefined and emitServerSocketEOFNT never runs for a non-upgrade socket read by a request handler. The new helper at :1329 reads response.hasBody correctly, so the PR knows the right accessor and leaves the wrong one in the same function. Fix: read response.hasBody at :1805 like :1329 does, or delete the dead branch and emitServerSocketEOFNT if the EOF it would emit is not wanted (it pushes null on the socket and never pushes null on req).

Extended reasoning...

Four finders saw this and all filed it as pre-existing. It is pre-existing, but the diff adds the corrected twin ten lines above and leaves this one, which is the 'fix the whole class' rule. I opened JSNodeHTTPServerSocketPrototype.cpp: the hash table has no hasBody entry; response at :536-547 is the only way to reach the NodeHTTPResponse whose get_has_body in NodeHTTPResponse.rs:797 produces the bits. So (undefined & 4) !== 0 is always false. Path: a request handler calls req.socket.on('data') or socket.resume(); socket._read at :1821 → #resumeSocket → :1802-1817; response.resume() returns a buffered chunk; :1810 never fires. Consequence today: emitServerSocketEOFNT at :3750 is dead; if a maintainer 'fixes' the accessor without reading it, emitServerSocketEOF(self) at :3742 is called without req, pushes null on the keep-alive socket and leaves req[eofInProgress] = true so IncomingMessage._read returns early forever at _http_incoming.ts:380 and 'end' never fires. Either the branch should be made live with the right accessor and req passed through, or deleted in this PR.…

Verification: pre-existing (nit). Trigger: a non-upgrade request handler reads req.socket (e.g. socket.on('data')/socket.resume()) after the body was buffered during a pause, so #resumeSocket reaches the non-upgrade branch at /home/claude/bun/src/js/node/_http_server.ts:1802-1817. Mechanism verified. At :1782-1783 const handle = this[kHandle]; const response = handle?.response; — handle is the…

…the new tests The resume at the switch to tunnel mode skipped a socket that upgrade() adopted inside the body callback by comparing it to upgradedWebSocket. That field is per context, and another connection's upgrade() in the same drain overwrites it. The check now reads the kind of the socket. The new tests reject their waits when a socket errors or closes, and the late-read case checks req.readableFlowing right after the read.

robobun · 2026-09-19T22:39:43Z

About the finding outside the diff (handle.hasBody at src/js/node/_http_server.ts:1802, in the branch of #resumeSocket for requests that are not upgrades): confirmed. JSNodeHTTPServerSocket has no hasBody, so that check is always false and emitServerSocketEOFNT never runs.

I did not change it in this PR. That branch is not on the Upgrade path. To make it live changes every request whose handler reads req.socket after a paused body: it pushes null on a kept-alive socket, and emitServerSocketEOFNT does not pass req on. It needs its own change with tests. I added it to the PR notes.

Only the last chunk sets `Complete`. One function, `leave_pending`, is the only other way out of `Pending`. | | Read flow control | One path: `push()` returning false stops the socket, `_read()` starts it. Both native pause buffers are removed: no read is copied and replayed. | | "This read is parsed" signal | `notifyWhenReadParsed()` sets a uws state bit. uws delivers a `readParsed` event after the read. It replaces a `setImmediate`. | | Close during a parse | One uws bit defers a close to the end of the current message. | | Response finish | A response is finished when it has ended and the socket has fully drained. | | Idle connection | One rule, `HttpResponse::closeIfIdle()`. A connection is idle when it receives no request (head or body) and no response is in flight, queued or undrained. The sweep of `close()` and `closeIdleConnections()` both use it. | | Idle tunnel | A tunnel at read EOF with nothing left to send. uws reports it to the server through the connection filter (`-3`, `+3`, `-4`). It still counts for `'close'`, but it does not hold the event loop, like a libuv handle in that state. | | Server `'close'` | One native close promise per `listen()`. `close()` records whether its sweep left nothing open. Then a `listen()` in the same tick cannot hold `'close'` back, as in `net.Server._emitCloseIfDrained`. | | Raw socket writes | While uws holds response bytes (its buffer, the zero-copy tail of a `res.write()`, the cork buffer), a raw write goes through `AsyncSocket::write`, the path a 1xx line takes. So the order on the wire is the order of the calls. | | Upgrade verdict | One scanner and one verdict, shared by the parser and the dispatcher. | | llhttp | Updated from 9.3.0 to 9.4.2, as Node v26.5.0 vendors it, plus one local patch (see below). Node v26.5.1 and later vendor 9.4.3. That update is not in this PR. | The parser changes also tighten request framing so that it agrees with llhttp in more cases. There is no new API surface. ### A pause holds from the next read The copy of the rest of a read (`nodeHttpPausedSpill`), its replay from a posted task and the nested parse are removed. Like in Node, the rest of the read that caused a pause is still parsed, and the socket stops at the next read. usockets reads up to 512 KB in one call. libuv reads 64 KB. | One paused, unread request (client sends 64 MB) | Bytes held | | --- | --- | | Node 25.6 | 131,018 | | This pull request | 524,234 | The price is in one case. A client sends 512 KB of small pipelined requests (19,418 of them) and never reads. Each handler answers with its own 64 KB body: | Handler | Runtime | Requests dispatched | RSS | | --- | --- | --- | --- | | Answers at once | Node 26.3 | 2,425 | +177 MB | | Answers at once | main | 41 | +9 MB | | Answers at once | This PR | 2,425 | +171 MB | | Answers one tick later | Node 26.3 | 4,850 | +336 MB | | Answers one tick later | main | 2,426 | +181 MB | | Answers one tick later | This PR | 4,850 | +330 MB | Release builds on Linux x64. This PR now does what Node does. main held fewer responses, mostly for a handler that answers at once. On macOS one read can return all 512 KB. There, Bun 1.4.3 already reached +951 MB for the handler that answers one tick later, and Node reached +1,294 MB. `server.maxRequestsPerSocket` bounds it. ### Performance #### Responses larger than 16 KB are faster, and now faster than Node On main, a response that did not fit the 16 KB uWS cork buffer released the cork. After that, each piece was its own `send()`: the buffered head, the chunk-size line, the data, the `\r\n` and the last chunk. Over TLS, each 2-byte piece was also its own record. Two changes fix that, for `Bun.serve` and for node:http: | Change | Effect | | --- | --- | | A write that does not fit goes out with the cork buffer and its framing in one vectored write | No copy is added. Over TLS, the records of all the pieces share the write batch that one `SSL_write` loop already had. | | The cork buffer holds 128 KB, up from 16 KB. Only a write of 16 KB or less is copied into it, as before. | Several writes in one tick go out in one write, like in Node. A longer write still goes out without a copy. | The bytes on the wire are the same. The vectored write uses `sendmsg()` with the flags that `send()` uses. Write syscalls for one response: | Response | Node 26.3 | main | This PR | | --- | --- | --- | --- | | 4 x `res.write(16 KB)` | 1 | 16 | 1 | | 40 x `res.write(2 KB)` | 1 | 16 | 1 | | `res.end(64 KB)` | 1 | 2 | 1 | | 256 KB file, `.pipe(res)` | 4 | 16 | 5 | Throughput (req/s, the mean of 2 rounds).

This PR is faster than Node in all eight. `Bun.serve`, measured on `a771572a8d`, before the larger cork buffer (req/s, the mean of 2 rounds): | Case | main | PR | Change | | --- | --- | --- | --- | | Direct stream, 4 x 16 KB | 6,826 | 12,479 | +83% | | 64 KB string | 16,944 | 20,145 | +19% | | TLS, 64 KB string | 15,045 | 16,892 | +12% | | hello (control) | 83,957 | 83,137 | -1.0% | These runs are on loopback, where the kernel send buffer is 2.6 MB and the work of the receiver runs inside `send()`. That is the best case for fewer writes. A new connection over a real network takes about 46 KB in its first write on Linux. The rest waits in the socket buffer, as it would after separate writes. #### Small responses are unchanged A small response is already one `recvfrom` and one `sendto` on both builds. `perf` puts 66% of the time of a hello-world server in the kernel, on both builds. CI release builds on Linux x64: main `97246d044e` (the merge base) against this PR `8834cd0787`. Both use the same WebKit. The server runs on one pinned core. `oha` sends 64 connections for 5 s after a 2 s warm-up. There are 2 rounds, and the order of the builds alternates. "Change" compares the means of the two rounds.

The RSS pass ran at the same time as the throughput runs, on other cores. The commits after `8834cd0787` change tests and add one version check to the node:http dispatcher. They were not measured. ### Supersedes | Theme | Pull requests | | --- | --- | | Request body | #43592 #43579 #38196 #43518 #43602 #43408 #43427 #43597 #43555 #43456 #43466 | | Tunnels | #43570 #43485. #43596 is a duplicate of #43570. | | Parser | #43182 #43161 #43326 #43327 #40505 #43363 #42532 #42194 | | Response write | #39386 #43371 #43548 #43499 #43496 #43464 #42008 #43549 | | Response finish | #40351 #43021 #41822 #43473 #42068 #35207 #43425 #43503 | | Lifecycle | #43413 #39686 #43028 #42727 #42622 #42610 #35837 #35839 #37825 #37749 #43376 #35268 | | JS API | #41691 #41738 #38036 #42462 #36527 #39718 #37964. #42947 merged on its own. | The close drain, `resetAndDestroy()`, the pending write callback handling and the response `'close'` ordering come from #42622 and #42727 by @steipete. The diagnosis and the tests for the stalled `ws` writes come from his #42610. Not included: | Pull request | Reason | | --- | --- | | #33061 | main already enforces `headersTimeout` and `requestTimeout` | | #41672 | It makes `http.createServer({ key, cert })` stop serving TLS. That needs a product decision. | | #37543 | A type refactor with no tests and no user-visible change | | #35465 | It makes `http.Server` extend `net.Server`. Only the prototype chains were joined. The `net.Server` constructor never ran, so `_handle` and `_connections` were `undefined`, and `_emitCloseIfDrained()` emitted `'close'` on a listening server. The server is backed by uWS, not `node:net`. | | The `AutoFlusher` removal in #42622 | It makes `flushHeaders()` flush at once. That is a performance change with no relation to the rest. | ### Tests | Check | Result on a debug build (macOS arm64) | Head | | --- | --- | --- | | Every test file that this PR touches (28 files) | 1,866 pass, 2 fail. The 2 failures are `serve.test.ts` "bounds memory when proxying ... to a stalled client". They fail the same way on a debug build of main. | `83af4da4a3`, run before the last commit of main came in | | `test/js/third_party/express` (9 files) and the `body-parser` test | 299 pass, 0 fail | `83af4da4a3`, run before the last commit of main came in | | Node 25.6 against Bun, 32 scenarios from two scripts (event order, framing, lifecycle) | No regression against Bun 1.4.3 | `0ff1a23f61` | | Every vendored Node `test-http-*` and `test-https-*` file, plus the `test-net-*` and `test-tls-*` files for pause, write, end and close | 535 of 537 exit 0. `test-http-agent-keepalive.js` and `test-https-timeout.js` fail on that debug build. Both pass on every CI lane. | `daee05fcfd` (before the rebase) | | The tests that depend on what the kernel takes in one send, on Windows Server 2019 x64 and Windows 11 arm64 | pass | `3eef223328` (x64), `a29289bcc1` (arm64) | | CI build 120191 (Linux, macOS and Windows, release and ASAN) | every lane passed | `daee05fcfd` (before the rebase) | Each new test fails on Bun 1.4.3, or on the commit before its fix for a fault that this branch introduced. The two tests over the limit are `node-http-connect.test.ts` ("tests should run on bun") and `node-http-syscall-fault.test.ts` ("racing a queued drain"). Each starts a debug subprocess that needs more than 5 s on this machine. Both pass on CI. ### Changes in the last push The branch is rebased on main (`daee05fcfd` was the head before). It is now linear. Four regressions against main, each with a test that fails without its fix: | Case | main | Before this push | Now (same as Node) | | --- | --- | --- | --- | | `emit('connection')` or http2 `allowHTTP1`: `res.end()` on a request that nobody reads | `'end'`, `'close'` | No events | `'end'`, `'close'` | | The same server, an unread 32 MB body | 0 bytes held | 32 MB held | 0 bytes held | | A NUL in a header value with `httpValidation: "relaxed"` (client, `HTTPParser`, `emit('connection')` server) | Accepted | The process spins forever | `HPE_INVALID_HEADER_TOKEN` | | `Connection: close`, body in the same read as the head, a 20 KB response before the body is read | `'end'` with an empty body | No events on `req` | `'end'` with the body, `'close'` | | An empty line on an idle keep-alive connection, then `server.close()` | 0 s | About 6 s | 0 s | | Fix | Where | | --- | --- | | The finish listener of a fallback connection dumps an unread request, like Node's `resOnFinish` | `http1_server_fallback.ts` | | llhttp patch: `llhttp__internal__c_test_lenient_flags_20` is false for a NUL. The relaxed state does not consume a NUL, and the next state sent it back there. 9.4.3 has the same loop. | `llhttp.c`, noted in its `README.md` | | A node:http socket that `onData` is parsing gets the close gate of `onData`, also when a large write released the cork | `HttpResponse.h` `uncorkCompletedResponse()` | | A read that starts no message leaves an idle connection idle | `HttpContext.h` `onData` | The open review threads are fixed in `8834cd0787`: `closeAllConnections()`, `Proxy-Connection: close`, five comments cut to one line, and the test of two overlapping listeners, which now waits on events. With the generation gate in `emitCloseServer` removed, that test fails in both cases. `AsyncSocketData` keeps its bools together, which takes it from 56 to 48 bytes per socket. `http.Server` no longer extends `net.Server` (see "Not included"). The special case for it in `Ipc.ts` is gone too. `child.send(msg, httpServer)` still throws `ERR_INVALID_HANDLE_TYPE`, and its test stays. <details><summary>Changes since the first revision (2988a61)</summary> Merged with main at `c8e1f6fa5b`. The one conflict was #43708 (`req.socket` emits `'end'` and `'error'`). Its state bit `HTTP_NODE_PEER_ENDED` moved to bit 22, because bit 19 is `HTTP_NODE_NOTIFY_READ_PARSED` here. Its 15 tests run in `node-http-server-abort-events.test.ts` next to the tests of this branch (103 pass). CI on `2988a610c` had ten red tests from four causes. They are fixed: - `ed882e5e99`: `write()` to a response without a body (HEAD, 204) does not wait for unsent bytes. - `811f817704`: an idle tunnel does not hold the event loop after `server.close()`. Four vendored Node tests timed out on every platform. - `0697deec11`, `d428824c08`, `7aec062d14`: the write callback tests use a body that backs up a loopback socket, and accept what Winsock does. - `c7af1c1615`: two tests from main asserted the old `close()` contract. Review findings, each reproduced against Node v26.3.0 and fixed with a test that fails without the fix: - `d4d2b783ea`, `2cc79939bb`, `45141abca9`, `9a63dbc470`, `80a23a1822`: the idle rule. A keep-alive connection is idle again when its body ends after its response. A connection that owes a queued pipelined response, that still receives a request head or body, or whose response still drains is not idle. - `87d8904aa3`, `7eca4f7806`: `close(cb)` followed by `listen()` in the same tick reports `'close'`, also for an https server whose only connection was idle. - `3fd7b25382`: a paused pipelined request behind a response that still drains stops the connection. The first revision read 512 MiB of 512 MiB into memory. - `2d1a5e2d8d`, `33e4683a8a`, `539cb41eb9`, `197c7dfc29`, `0490e3540b`: raw socket writes stay behind every unsent response byte. The cases were a CONNECT pipelined behind a response that still drains (its `200` landed at offset 2.6 MB of a 64 MiB body), a zero-length tunnel write (it hung the tunnel), the 400 replies above, the zero-copy tail of a large `res.write()`, the cork buffer, and Windows 11, where the kernel takes the whole response and refuses the next send. - `0abd39c133`: an upgrade from the request's `'end'` listener keeps the body bytes out of the WebSocket. The connection closed with 1006 right after the 101. - `5aafc61aa6`: the callback of a small `res.write()` that the kernel refuses at the uncork runs on the drain. Reproduced on Windows 11 only. - `a29289bcc1`: a tunnel write that waits for a drain settles its callbacks when the connection closes. Known differences from Node that this PR leaves: - A handler that calls `res.end()` and then `server.close()` closes its keep-alive connection at once. Node waits for the `keepAliveTimeout`. - A pipelined Upgrade behind a response that still drains is served as a plain request. - An `end()` on a tunnel with no write pending, while the response before the CONNECT still drains, closes both directions after the flush. Node half-closes. - A raw `req.socket.write(big)` and `req.socket.end()` with no `res.end()` sends every byte but no FIN. main loses bytes here. - A CONNECT socket that is given back with `server.emit('connection', socket)` answers only the first of several pipelined requests. main answers none. - A large write from an `'upgrade'` listener stalls while the body of that Upgrade request is still pending. A second `listen()` on a listening server does not throw. Both are the same on main. - A tunnel write that fails because the client went away fails its callbacks but emits no `'error'`. Node emits `ECONNRESET`. A new `'error'` could end a process that has no listener for it. </details>  --- **no test proof** · iteration 8 · platform-specific test(s) that do not run on this machine, deferring to CI, which covers all platforms: test/js/web/fetch/fetch.stream.test.ts, test/js/node/url/url.test.ts, test/js/node/tls/tls-syscall-fault.test.ts, test/js/node/net/node-net-server.test.ts, test/js/node/http/node-http.test.ts, test/js/node/http/node-http-syscall-fault.test.ts, test/js/node/http/node-http-server-close-drain.test.ts, test/js/node/http/node-http-connect.test.ts, test/js/node/http/node-http-backpressure.test.ts, test/js/node/child_process/child_process_ipc_handle.test.ts, test/js/bun/http/serve.test.ts, test/js/bun/http/serve-syscall-fault.test.ts, test/js/bun/http/bun-server.test.ts  --------- Co-authored-by: Jarred Sumner <jarred@jarredsumner.com> Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
