The bug

GitHub reports a job killed by timeout-minutes as cancelled, the same conclusion a run gets when a newer one takes its concurrency group. The publish job excluded cancellations wholesale, which is right for a supersede and silent for a timeout.

Seen tonight on run 32070723229: the suite hit its cap, published nothing, and left Tests Verified at pending. The pull request read as "suite still running" indefinitely, with no failure anywhere to say otherwise. That is the one direction this file is careful never to fail in.

The fix

The two cases are told apart by who owns the pending status. The gate writes it with the run's own URL at the start, so a superseding run has already replaced it by the time the older run reaches publish.

  • URL is not ours: superseded, exit without writing, which preserves the existing guarantee that a stale run never buries a newer one's result.
  • URL is still ours after a cancellation: nothing came to replace us, so it was the timeout or a person, and the status goes red with "did not finish, timed out or was stopped".

No extra API surface: it reads the status the gate already publishes.

Also, the cap comes down to 20 minutes

Measured rather than guessed. The last eight passing runs took 11 or 12 minutes each:

32075172879  success  11min
32073315715  success  11min
32069417278  success  12min
32068344347  success  11min
32068269528  success  11min
32066934692  success  11min

20 leaves about seventy percent of headroom over the worst of them. At 25, the two stuck runs tonight burned most of an hour of runner time before anyone looked.

Worth recording why the per-step timeouts do not solve this on their own: they sum to over an hour, because each has to allow for its own worst case, so the job cap is always what a genuinely stuck run hits first. That is acceptable now that hitting it reports something.

Summary by CodeRabbit

  • Bug Fixes
    • Improved integration test workflow handling for timeouts, cancellations, and superseded runs.
    • Prevented outdated or superseded runs from publishing incorrect status updates.
    • Added clearer success, cancellation, timeout, and failure reporting for automated test runs.
    • Reduced the maximum integration test duration to provide faster feedback when suites take too long.

GitHub reports a job killed by timeout-minutes as `cancelled`, the same
conclusion a run gets when a newer one takes its concurrency group. The publish
job excluded cancellations wholesale, on the reasoning that a superseded run
must not overwrite the newer one's status. Correct for that case, and silent for
the other: run 32070723229 hit its timeout, published nothing, and left `Tests
Verified` pending. The pull request read as "suite still running" with no
failure anywhere to say otherwise.

The two are now told apart by who owns the pending status. The gate writes it
with the run's own URL when the run starts, so a superseding run has already
replaced it by the time the older one reaches publish. A URL that is not ours
means superseded, and the job exits without writing. A URL that is still ours
after a cancellation means nothing came to replace us, so it was a timeout or
someone stopping it by hand, and either way the honest answer is failure.

The job cap comes down from 25 minutes to 20 while here. Eight consecutive
passing runs took 11 or 12 minutes, so 20 is ample, and 25 meant most of an hour
of runner time across the two stuck runs seen tonight. The per-step timeouts are
not the binding limit and cannot be: they sum to over an hour, since each has to
allow for its own worst case.

📝 Walkthrough

Walkthrough

The workflow reduces the integration suite timeout to 20 minutes. The publish job handles cancellations, verifies status ownership, skips superseded runs, and publishes distinct status results.

Changes

Integration status control

Layer / File(s) Summary
Integration suite timeout
.github/workflows/integration-tests.yml
The integration suite job timeout changes from 25 to 20 minutes.
Cancellation-aware status publication
.github/workflows/integration-tests.yml
The publish job runs for cancelled suites, checks the current status owner, skips superseded runs, and publishes separate success, failure, and cancellation results using environment variables.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 2eeba

A cancelled run can still overwrite a newer run's required test status if both updates interleave, leaving pull requests showing an obsolete result or incorrect verification state. The PR should not merge until this race is fixed or explicitly accepted by the owner.

Comment thread .github/workflows/integration-tests.yml
The ownership read and the status write are two requests, so a newer run can
claim the status in between. Left open on purpose and now said so in the file:
POST /statuses has no conditional write to close it with, and every way of
losing the race ends in a red status that blocks a merge, which the newer run
corrects when it publishes its own result.
