Summary

Found while diagnosing why PR #550's e2e gate checks stayed BLOCKED for hours despite the real gate job succeeding: an invalidate-e2e-gates API placeholder (in_progress, unlock-time) was left permanently unresolved because nothing triggers cleanup unless a new push happens. complete-stale-e2e-gates (osac-test-infra #542, already merged) fixed the general case by running follow-up cleanup jobs right after each native gate job — but nothing handles the case where a PR closes (merged or not) while work is still in flight or an orphan is still sitting in_progress. That's a separate gap from #542, not a duplicate of it.

This adds a pull_request_target: closed handler that:

  • Cancels every in-flight full-install run for the PR, via a new CANCEL_ALL mode on cancel-stale-e2e-runs.sh (the existing script explicitly skips the current head SHA by design, since it's built for the synchronize/obsolete-SHA path — this reuses it rather than duplicating it)
  • Dismisses any remaining in_progress e2e-*-gate orphan checks, reusing complete-stale-e2e-gates's existing after-native-success: false path as-is — no changes needed in osac-test-infra, that mode already does exactly this unconditionally

Test plan

  • YAML validated, actionlint clean
  • bash -n on the modified script
  • Verified the new CANCEL_ALL jq filter locally against mock run data: false mode still only matches obsolete SHAs (unchanged behavior), true mode matches all SHAs
  • End-to-end: close/merge a PR with e2e still in flight and confirm the runs get cancelled and no orphan checks remain

Summary

  • CI: Added closed pull request cleanup for main.
  • CI: Added a live-state guard before cleanup.
  • CI: Added CANCEL_ALL mode to cancel matching full-install E2E runs for the exact pull request.
  • CI: Dismisses remaining in_progress E2E gate checks.
  • Security: Uses base-repository execution and scoped write permissions.
  • Validation: Added YAML, shell syntax, and jq-filter validation. End-to-end testing remains pending.
  • API, controllers, database, authentication, deployment, and documentation: No changes.

Backward compatibility

No application or public API behavior changes. The change affects CI cleanup only. A reopened pull request is protected from delayed cleanup runs.

Risk classification

risk:ship — The change is limited to CI automation. It uses exact pull request matching, checks the current pull request state, and uses scoped permissions. It does not affect production runtime behavior, data, authentication, or public APIs.

The change is close to risk:show because it changes visible CI behavior. It does not qualify because the impact is limited to pull request cleanup.

Walkthrough

The PR adds CANCEL_ALL support to the E2E cancellation script and gates closed pull request cleanup on the live pull request state.

Changes

Closed PR E2E cleanup

Layer / File(s) Summary
PR-scoped all-run cancellation
.github/scripts/cancel-stale-e2e-runs.sh
CANCEL_ALL requires PR_NUMBER and selects matching full-install E2E runs by head SHA and pull request number. The script updates cancellation logs and the final count message.
Live pull request state guard
.github/workflows/e2e-cancel-on-pr-close.yml
A guard job reads the live pull request state. E2E run cancellation and orphaned gate dismissal run only when the pull request remains closed.

Two of three findings verified as real and fixed, one skipped:

Line 82 (cancel-stale-e2e-runs.sh) — valid, fixed. CANCEL_ALL drops the "differs from HEAD_SHA" scoping, leaving repo+branch as the only match criteria for which runs to cancel. Not sufficient on its own if a branch name is ever reused across PRs (delete-and-recreate, or a stale run surviving a prior close/reopen cycle). Now also requires an exact match against PR_NUMBER in each run's pull_requests list when CANCEL_ALL is set. Tested locally against mock run data: a same-branch run belonging to a different PR number is now correctly excluded, and the non-CANCEL_ALL path (used by the existing synchronize handler) is unaffected.

Line 34 (e2e-cancel-on-pr-close.yml) — valid, fixed. Added a guard job (pull-requests: read) that re-checks live PR state before either cleanup job runs, covering the case where a queued/delayed pull_request_target run fires after the PR was reopened. Both cancel-in-flight-runs and dismiss-orphan-gates now needs: guard and only run when it confirms the PR is still closed.

Line 42 (pin to commit SHA) — skipped. Checked the rest of the repo first: e2e-cancel-stale-runs-on-push.yml and all three e2e-*-full-install.yml files already reference this exact same complete-stale-e2e-gates@main action, unpinned, and those are already merged. This is an established convention here, not something this PR introduced — pinning only this new caller would just be inconsistent with the other four without a broader team decision to pin all of them.

Pushed as 4d860a7. YAML/actionlint/bash -n all clean, jq filter changes verified against mock data before pushing.

Closed PRs can be reopened at any time if they are still relevant.

Nothing previously stopped e2e work once a PR was no longer around to
need it. cancel-stale-e2e-runs.sh only cancels runs on obsolete SHAs
(by design, for the synchronize path) and explicitly skips the current
head SHA, so a merged/closed PR's in-flight full-install runs kept
running to completion for no reason, and any in_progress invalidate-
e2e-gates placeholder checks on that SHA were left permanently
unresolved -- nothing left to trigger the existing after-native-success
cleanup path once the PR is gone.

Adds a new pull_request_target: closed handler that:
- Cancels every in-flight full-install run for the PR (new CANCEL_ALL
  mode on cancel-stale-e2e-runs.sh, including the current head SHA --
  there's no newer push to defer to once the PR is closed)
- Dismisses any remaining in_progress e2e-*-gate orphan checks via the
  existing complete-stale-e2e-gates composite action's
  after-native-success: false path, reused as-is from osac-test-infra

No changes needed in osac-test-infra: the composite action already
supports exactly this unconditional-dismiss mode.
Two of three findings verified as real, one skipped with reason:

- cancel-stale-e2e-runs.sh: CANCEL_ALL dropped the "differs from
  HEAD_SHA" scoping, leaving repo+branch as the only match criteria --
  not enough if a branch name is ever reused across PRs (delete and
  recreate, or a stale run from a prior close/reopen). Now also
  requires an exact PR_NUMBER match against each run's pull_requests
  list when CANCEL_ALL is set; verified locally against mock run data
  that this correctly excludes a same-branch run belonging to a
  different PR number, and leaves the non-CANCEL_ALL path unaffected.

- e2e-cancel-on-pr-close.yml: added a guard job (pull-requests: read)
  that re-checks live PR state before either cleanup job runs, in case
  a queued/delayed pull_request_target run fires after the PR was
  reopened. Both existing jobs now depend on it.

- Skipped: pinning complete-stale-e2e-gates@main to a commit SHA. Four
  other already-merged files in this repo
  (e2e-cancel-stale-runs-on-push.yml and all three
  e2e-*-full-install.yml) reference this exact same action unpinned at
  @main -- this is an established repo-wide convention, not something
  this PR introduced. Pinning only this new caller would be
  inconsistent without a broader decision to pin all of them.
