From c28227bffc60a2da3fe78e2d83fc02cb3e2f6b31 Mon Sep 17 00:00:00 2001 From: austinpower1258 Date: Tue, 8 Sep 2026 04:40:45 -0700 Subject: [PATCH 01/32] ci: guard reusable-workflow permission grants (red on main's shape) GitHub validates a reusable workflow's permissions against the calling job when it parses the caller. A callee that requests a scope the caller does not grant fails the whole caller run at startup, before any job runs. That is what blocks the stable release today: release.yml calls ios-screenshots.yml, which requests `actions: write` while release.yml grants none (#12149). Add scripts/ci/check_reusable_workflow_permissions.py (python3 stdlib only) that walks every local `uses: ./.github/workflows/*.yml` call, computes the calling job's grant (job block, else workflow block, else the repository default) and the callee's request (max over its workflow block and every job block, gated jobs included, mirroring 4b9720dc750), follows nested calls with the intermediate grant, and fails on any scope that asks for more. tests/test_ci_reusable_workflow_permissions.py covers the rule on fixture trees (the exact #12149 shape, shorthands, job-level overrides, repository defaults, nesting, missing callees) and then runs the checker on the real tree, which fails until the next commit fixes the workflows. Wired into the workflow-guard-tests job in ci.yml.

When #11342 made release.yml call this workflow, GitHub compared the callee's block with the caller's grant (contents/attestations/id-token only) and refused the release workflow at parse time: startup_failure, no job run, for tag pushes and dispatches alike (#12149). Reduce the callee to `contents: read`, the minimum its steps use. Widening release.yml instead would have handed a UI-test job the ability to cancel or dispatch runs for no benefit. The guard added in the previous commit now passes on the tree.

The DMG never consumes those artifacts: nothing in build-sign-notarize downloads them, and the App Store tooling (ios/scripts/appstore-shots.sh capture) dispatches its own ios-screenshots.yml run rather than reading a release run. What the gate did do was make every stable macOS release wait for, and fail with, a 300-minute simulator capture across nine locales on shared macOS runners, a lane that had "not compiled on main for days" before #11342 healed it. Keep the capture in release.yml as a sibling job, so every tag still gets screenshots at the exact release ref and a failed capture still turns the run red, but drop it from build-sign-notarize.needs. Trade-off: a green macOS release no longer implies the screenshot capture succeeded; the run conclusion still does. tests/test_ci_release_ios_screenshots_decoupled.sh pins the policy (fails on main's needs list, passes here) and runs in workflow-guard-tests.

Set job-level `permissions: contents: read` on the calling job (the pattern the cmux-tui callers already use) instead of passing the workflow's contents/attestations/id-token write grant through, and drop `secrets: inherit`, which handed every repository secret (Developer ID certificate and password, notarization credentials, Sparkle private key, R2 keys, Sentry token, ASC key) to that job for no benefit. Trade-off: if the release lane ever wants the ASC upload, it must add `secrets: inherit` back together with `upload: true` and relax the callee's dispatch-only guard.

On plain main it fails (CURRENT_PROJECT_VERSION 102 equals the published 0.64.22 build), which is correct for a tag push about to publish but wrong for the workflow's built-in dry run: a non-tag workflow_dispatch publishes nothing and, by design, runs from a branch that has not been bumped yet. The dry run was therefore impossible without a throwaway bump commit. Chosen fix: a CMUX_SPARKLE_MONOTONIC_MODE switch on the guard, `enforce` by default (tag pushes, scripts/release-pretag-guard.sh) and `warn` when release.yml runs from anything but refs/tags/*. Rejected alternative: running the dry run from a throwaway branch with a temporary bump, which would validate a commit that never merges and leave the pipeline un-dry-runnable for everyone else. tests/test_sparkle_build_monotonic_modes.sh drives the guard against fixture project files and a local appcast (stale fails in enforce and by default, warns in warn mode, bumped passes in both, unreachable appcast soft-passes, unknown mode fails) and pins the ref-based selection in release.yml. Wired into workflow-guard-tests.

The budget was 20 x 15s. Nightly run 34208928547 (2026-09-08) exhausted it: Accepted at 09:51:28, still "Unnotarized Developer ID" at 09:56:18, exit 3, whole universal lane failed, while the arm64 and x86_64 lanes passed in the same window. Raise the default to 80 x 15s (twenty minutes) and announce the budget on the first rejection so a log reader can tell propagation from a hang. Trade-off: a genuinely rejected helper now takes up to twenty minutes to fail instead of five, which only delays an already-lost release; a short budget failed good releases, each costing a full rebuild and a human retry. Both knobs remain env-configurable (CMUX_GATEKEEPER_ASSESS_ATTEMPTS/_DELAY_SECONDS). nightly's signing job has an 80-minute timeout with a 7-10 minute typical duration, so the budget fits there; release.yml's timeout is raised in the next commit. tests/test_notarize_computer_use_helper.sh now pins the defaults (at least 1200s, polled at least every 30s, env-configurable literals) and the budget announcement, alongside the existing override and give-up coverage.

Since then the job gained the Cloud tunnel system extension and its Go engine build (#11789), the universal diff sidecar and cmux-tui client install (#12006), two extra smoke launches, and a Gatekeeper propagation wait that can now run twenty minutes on its own. A 60-minute ceiling leaves no room for a slow notarytool day, and a timeout mid-notarization wastes the whole build. 90 minutes covers the measured baseline plus the known variable waits with headroom while still bounding a hung job on a shared self-hosted runner. To be re-checked against the dry-run duration for this branch: the timeout must stay at least 25 percent above it.

The Release build's PRODUCT_BUNDLE_IDENTIFIER for the extension is com.cmuxterm.app.tunnel; only NEMachServiceName ($(CMUX_TEAM_ID_PREFIX)$(PRODUCT_BUNDLE_IDENTIFIER)) and the provisioning profile's com.apple.application-identifier carry the team prefix, and the app activates whatever CFBundleIdentifier the bundled extension declares. nightly.yml already does it this way and ships com.cmuxterm.app.nightly.tunnel.systemextension with a profile for 7WLXT3NR37.com.cmuxterm.app.nightly.tunnel (run 34220568401). The mistake was invisible until now because release.yml could not start at all. Use the bundle identifier for the normalize call and the directory the verify step inspects; keep the App ID for the profile check. tests/test_ci_release_tunnel_identifiers.sh derives all three from cmux.xcodeproj/project.pbxproj (fails on main's release.yml, passes here) and runs in workflow-guard-tests.

Fix both at the root rather than refreshing the budget: - swift-package-tests: FakeTerminalEngine.swift gained a `UUID` parameter in #10564 but imports only GhosttyKit. Add `import Foundation`. - tests-build-and-lag (scripts/swift_warning_budget.py, actual > budget): * AppDelegate+PaneMemoryGuardrail.swift: parenthesize the two `compactMap` closures inside the `guard` condition ("trailing closure in this context is confusable with the body of the statement"). * SessionIndexTableController.swift: the bounds-change observer block is typed @Sendable in the current SDK, so referencing `isApplyingRows` and `reconcilePresentation(in:)` warned. The block is delivered on `queue: .main`, so run it under `MainActor.assumeIsolated`, the same pattern SidebarWorkspaceRowCellView uses; no async hop, same timing. * CmuxTuiSnapshotParser.swift: `switch resourceID.kind` already covers every SurfaceResourceKind case (terminal, display, browser), so the `default: continue` could never run. Remove it; a new case now fails to compile here instead of being silently skipped. * SurfaceCatalogModel.swift: `if let rowID,` rebound a value the body never read; test `rowID != nil` instead. * TerminalController.swift: `payload` in the `.delivered` branch is never mutated; make it `let`. Every change is behavior-preserving. Verified with `swiftc -parse` on each file locally (no app build on the shared machine); the routed CI lane proves the build and the budget.

The job log shows why: ./scripts/sparkle_generate_appcast.sh: line 93: delta_args[@]: unbound variable A tag push would have published a GitHub Release without appcast.xml, so no Sparkle client would ever be offered the update, and the R2 stable appcast upload would then fail after the release already existed. tests/test_sparkle_generate_appcast_no_deltas.sh runs the real script with fake git/xcodebuild/generate_appcast/sign_update tools under every bash on the machine (/bin/bash 3.2 on macOS reproduces the bug; bash 5 never did) and requires a signed appcast at the requested output path with no delta arguments when there are no previous archives, and with --maximum-deltas when there are. It also requires release.yml to verify the feed after generation instead of trusting the exit status. Fails on main's script and workflow; the next commit fixes both. Wired into workflow-guard-tests.

In bash 4.4+ an empty array expands to nothing; in bash 3.2 (macOS /bin/bash, which `#!/usr/bin/env bash` resolves to on the release runner) it is an "unbound variable" error under `set -u`. Worse, with the script's EXIT trap bash 3.2 then exits 0, so the step passed and no appcast was written. Nightly always has previous archives (delta_args non-empty) and was never affected; the stable release lane never has them and has been broken since 2026-09-03, unnoticed because release.yml could not start at all (#12149).

It updated the Python hook tests to the new wire contract but not ClaudeHookLifecycleCleanupTests, whose two moved-pane tests still expected the removed command. They fail on main in the strict app-host agent-notification step (shard 6), unnoticed because #11976's PR CI never routed the macOS lane. Assert the new contract instead: the journal event for the hook names the re-homed workspace and the live pane (via the existing AgentJournalAppendCapture parser), and nothing still wipes the whole destination workspace. SessionEnd keeps sending the v1 command, so its tests are unchanged.

Today's logs (run 34236235360, shards 1/2/4, both attempts) show the mechanism, and it is two plumbing defects rather than the tests: 1. scripts/ci/xcodebuild_noninteractive.py resets its 300s idle deadline on every output chunk. Since #11755 (merged 2026-09-03T02:09Z, after the last green lane at 2026-09-02T09:21Z) the app host logs every Cloud API poll, `[CloudVM] GET /api/vm not_signed_in`, every 45 seconds. A test host hung inside a WebKit page load (WebContent XPC: "Could not signal service ... 113") therefore never looks idle, so the wrapper's kill and retry path, which handled the same WebKit failure on the 09-02 green run, never fires. 2. The tolerant batch watchdog in ci.yml (1800s) killed only the console-session launcher and left the lock wrapper, xcodebuild and the app host alive; the app host kept the `| tee` pipe open, so the step sat idle from "timeout after 1800s; terminating" until the job timeout. Fixes: - CMUX_XCODEBUILD_NONINTERACTIVE_IDLE_IGNORE_RE: output lines matching it do not count as progress. run-app-host-xcodebuild.sh defaults it to the Cloud poll line (an empty value restores counting everything; an invalid regex fails closed with exit 2). Real output still resets the clock, so a slow but progressing batch is unaffected. - The ci.yml batch runner writes xcodebuild output to the capture file and streams it with a detached tail, kills the whole process tree (pgrep -P recursion, TERM then KILL) when the batch budget expires, and reads both the streamed and per-batch captures for the SwiftPM retry heuristic. Behavior tests: tests/test_ci_xcodebuild_noninteractive_helper.py drives a child that prints only the keepalive every 50ms (finishes without the pattern, idles out at 0.3s with it, invalid pattern exits 2); tests/test_ci_change_areas.py runs the real step script against a runner that hangs and leaves a grandchild holding stdout, and requires exit 124 within seconds with the grandchild dead.

After the watchdog kills a batch (status 124) the capture can still hold an earlier attempt's summary (run-app-host-xcodebuild.sh retries into the same file), so a terminated batch could be reported as passed. Treat 124 as terminal before the normalization. The hung-runner behavior test now prints a decoy "(0 unexpected)" summary before hanging and requires the step to stay at 124 without the "All failures ... are expected" message. Also drop the `elapsed < 60` assertion from that test: the harness's 120s subprocess timeout already bounds a runaway step, and a hard wall-clock ceiling only adds scheduler-delay flakes.

The shared accept loop fulfills that expectation when the listener closes at the end of the helper, so XCTest ended `testCoderouterUnknownVerbStillPassesThroughToTheInstalledCLI` and `testCoderouterClaudeAddOAuthTokenRejectsAPIKeyShapeBeforeTheSocket` with "Failed due to unwaited expectation", which it counts as an *unexpected* failure.

Capture each suite's output and rerun the suite exactly once, only when xcodebuild printed "Restarting after unexpected exit, crash, or test timeout". An assertion failure never earns a rerun and a second crash still fails the shard, so the gate keeps rejecting real regressions. tests/test_ci_change_areas.py drives the real step script against a fake console runner: crash-then-pass is green with three invocations, an assertion failure exits 65 after one invocation, and two crashes exit 65 after two.

The hang sample shows SSHPTYAttachReconnectInputFilterTests.stdinPumpFiltersReadyInputBeforeStopSignal parked in stopFiltering() -> read() on the stop-acknowledgement pipe with every other visible cooperative-pool thread also inside a test body's synchronous wait. The pump under test is a detached task that needs one of those same threads, and the five pump tests each hold a thread for the ~13s reconnect probe deadline while running concurrently, so the suite can leave no thread for any pump (the family issue #12180 tracks). Run the suite serialized so at most one test parks a thread at a time, and bound every wait: stopFiltering now takes a 30s acknowledgement timeout and must succeed, and the EOF/exact reads poll with the same deadline. A pump that never gets scheduled now fails its test inside the batch instead of parking the shard until the idle timeout retries are exhausted. The two assertions in this suite that already fail on main (readUntilEOF == forwardedInput in stdinPumpFiltersReadyInputBeforeStopSignal and stdinPumpKeepsFilteringLateProbeRepliesAfterInitialDrain) are unchanged; the batch classifier tolerates them today.
