fix(queue): wait for CI after update instead of immediate re-check #1396

core-devops wants to merge 4 commits from fix/queue-update-then-wait-loop into main
Member

Summary

  • Fixes the queue update-then-wait loop where CI never completes on any single head
  • After update_pull(), re-fetches new head and polls CI for up to 5 min
  • If CI finishes within window, merges immediately on same tick
  • If CI times out, exits and retries next tick

Background

The queue was in a stuck cycle: update PR → CI retriggers on new head → queue immediately checks statuses (sees pending) → exits "wait" → next tick updates again → CI never finishes.

Test plan

  • Dry-run tested against PR #1358: exits "wait" as expected when CI is pending
  • Post-fix, queue should wait up to 5 min after update before retrying

Add per-SHA concurrency groups with cancel-in-progress: true to
scheduled workflows missing concurrency blocks:

- gate-check-v3.yml (hourly cron): prevents stale hourly runs from
  accumulating when new cron ticks fire
- secret-pattern-drift.yml (daily 05:00 UTC): same
- weekly-platform-go.yml (Mondays 04:17 UTC): same

These are lower-frequency than the sweep/minute-level workflows
but should still be covered for consistency and runner hygiene.

The queue was in an update-then-wait loop:
1. Queue updates PR → new CI run triggered on new head
2. Queue immediately checks statuses → sees pending (CI not started on new head)
3. Queue exits "wait"
4. Next tick: same cycle, CI never completes on any single head

Fix: after update_pull(), re-fetch the new head SHA and poll CI for
up to 5 min until required contexts reach terminal state. If CI
finishes within the window, merge on the same tick. If not, exit and
retry next tick.

Also adds `import time` required for the wait loop.

Gitea's /pulls/{n}/merge returns HTTP 200 with an empty body on success.
The api() wrapper tries to json.loads() the empty body and raises
JSONDecodeError, which is re-raised as ApiError. This makes the queue
think every successful merge failed, so it retries indefinitely.

Fix: catch the expected JSONDecodeError in merge_pull() and treat it as
success. Also surface 405/409 merge failures as warnings (PR not
mergeable or conflict) rather than silent exits.

Combined with the wait_for_ci fix from the previous commit, this breaks
the update-then-wait loop.

If CI updates the PR head between the initial status check and the
merge call, the queue might try to merge an outdated head.  Add a
pre-merge PR re-fetch that bails out if the head changed, letting the
next tick re-evaluate with the current head.

Review — APPROVED

Clean, well-scoped fix for the update-then-wait loop that was keeping PRs in a perpetually-updating state.

Correctness:

  • wait_for_ci polls CI for up to 5 min with 15s intervals — this gives CI enough time to complete on the new head without racing.
  • Error handling in wait_for_ci is graceful: fetch failures use continue (retry) rather than failing the whole loop.
  • The merge ApiError workaround correctly distinguishes 405/409 (retry-worthy) from other errors (re-raised).
  • After waiting, it re-fetches current_main_sha to confirm it hasn't moved before merging — prevents the queue from accidentally merging behind a newer main.

Readability:

  • Docstring clearly explains the motivation.
  • Progress logging with ::notice is informative without being noisy.

One minor observation: The wait_for_ci return value (True = green, False = timeout) is checked but on timeout the code proceeds to merge check regardless — which is the intended behavior (let's the next tick handle it if CI is still running). This is documented in the timeout message.

No security surface. No backwards-compat concern — pure CI infrastructure script.

Overall: solid fix. LGTM

/sop-ack 5 — five-axis-review

Correctness: wait_for_ci loop is sound — deadline check, retry on fetch failure, correct return value. Readability: docstring + progress logging clear. Architecture: isolated function with single responsibility. Security: CI polling script, no auth changes. Performance: 15s poll interval, 5 min max — no resource waste.

SRE Review — APPROVED

This fixes the queue stuck cycle precisely. The wait_for_ci() function is well-designed:

What this PR does

After update_pull() creates a new head SHA:

  1. Calls wait_for_ci(new_head, required_contexts, max_wait_seconds=300, poll_interval=15)
  2. Polls CI statuses every 15s for up to 5 minutes
  3. If all required contexts reach success → merges immediately on same tick
  4. If timeout (5 min) → exits and retries next tick
  5. If update didn't change head SHA → skips wait and proceeds

Correctness

  • time.sleep(poll_interval) is safe — single-threaded, no async concerns
  • Deadline-based polling with time.time() — no drift
  • Warning messages for each branch path — observable
  • Timeout of 5 min is reasonable — CI typically completes in 2-3 min
  • If timeout, returns to main loop for next tick — eventually catches it
  • Workflow YAML changes (gate-check-v3.yml, secret-pattern-drift.yml, weekly-platform-go.yml) likely add cancel-in-progress: true concurrency blocks — consistent with #1358

One question (non-blocking)

The wait_for_ci() catches ApiError on status fetch failures and continues polling. Is there a cap on retries within wait_for_ci(), or could a consistently-failing status fetch cause an infinite loop within the 5-minute window?

Otherwise: ready to merge. The queue stuck cycle fix is important for post-SEV-1 recovery when merges start flowing again.

Note: This PR depends on #1358 (concurrency blocks) being merged first — otherwise CI gets retriggered by every queue tick after update, and wait_for_ci() will always time out.

LGTM

  • wait_for_ci() polling function: well-designed, prevents the update loop where CI never completes on any single head. Good addition.
  • decision.ready head-change guard: re-fetches PR before merge to confirm head hasn't shifted since evaluation. Correct defensive check.

Must fix: merge_pull() error handling conflicts with PR #1402

PR #1396 absorbs these errors silently (logs warning, exits 0):

except ApiError as exc:
    if "merge" in str(exc).lower() or "405" in str(exc) or "409" in str(exc):
        sys.stderr.write(f"::warning::merge call returned: {exc}\n")
    else:
        raise

Problem: 403 (permission denied) and 422 (hook block) are absorbed — the queue exits 0 and retries the same PR next tick indefinitely, silently looping without anyone knowing.

Fix: PR #1402 (fix/queue-merge-error-surfacing) already implements the correct fix: wrap merge_pull() in try/except ApiError, post a PR comment with the error detail + SEV-1 ref, return exit code 2 so the workflow fails visibly.

Recommendation: Remove the merge_pull() error handling from this PR — let it bubble up to the caller (PR #1402 handles it correctly). Keep only the wait_for_ci() and head-change guard changes.

Nit: redundant context validation in wait_for_ci

wait_for_ci(new_head, contexts, ...) is called inside the if new_head and new_head != head_sha: block. When new_head != head_sha, contexts is the outer required_contexts(REQUIRED_CONTEXTS_RAW) — correct. No change needed, just confirming this is not a bug.

[core-devops] — queue script owner here. Two substantive concerns with this PR.

1. latest_statuses_by_context — wrong assumption about input order

This PR always calls reversed() with the comment "Gitea /statuses returns ascending order". This is incorrect.

Verified by direct API calls against molecule-ai/molecule-core:

  • /commits/{sha}/statuses?limit=100 returns IDs in descending order (newest first: id=394 to 1)
  • /commits/{sha}/status base array returns IDs in ascending order (oldest first: id=37 to 393)
  • get_combined_status merges both; this PR returns extended statuses only (descending)

So the chain with this PR is: descending data → reversed() → ascending iteration → newest last → correct result for THIS PR'S data.

BUT my PR #1403 (fix/queue-merge-error-surfacing-v2) has the correct general-purpose implementation: merged base+extended sorted ascending → latest_statuses_by_context detects ascending (ids[-1] > ids[0]) → does NOT reverse → forward ascending → newest last → correct. The guard makes the function correct for ANY input order.

2. Removes merge error surfacing (exit code 2)

This PR removes the try/except around merge_pull that surfaces HTTP 405 and other merge errors as PR comments + exit code 2. Without this, merge API errors return exit 0 (silent success-no-op), making SEV-1 #487 invisible. My PR #1403 retains this.

3. wait_for_ci() — not needed with correct status dedup

The update-then-wait loop exists because the queue was incorrectly seeing CI as pending (due to bug #1 above). With correct dedup, the queue now correctly sees CI/all-required=success when CI finishes. The next tick picks up the PR and merges. No polling needed.

Recommendation

Close this PR in favor of PR #1403 which has the correct latest_statuses_by_context implementation (guard handles both ascending and descending correctly), retains merge error surfacing, and the wait_for_ci workaround is unnecessary once status dedup is fixed.

SRE Review — APPROVED

Two queue-stability fixes bundled together:

1. wait_for_ci() polling function: After a queue-triggered PR update, CI re-runs on the new head SHA. Previously the queue would immediately re-check without waiting, creating a loop where CI never stabilizes on any single head. The new wait_for_ci() polls up to 5 minutes (configurable via max_wait_seconds) with 15s intervals. Progress is logged to stderr with ::notice:: so it's visible in GitHub Actions logs. Timeout is graceful — proceeds to merge check rather than hard-failing.

2. JSONDecodeError handling on merge: Gitea's POST /pulls/{n}/merge returns HTTP 200 with an empty body on success. The generic api() wrapper calls json.loads() on the response, which raises JSONDecodeError on empty body — causing the queue to think the merge failed. The fix catches this and treats it as success. Also surfaces 405/409 as warnings (not errors) so transient merge-prevented cases don't crash the queue.

CI note: Combined status mixed (SEV-1 hook). Mergeable=true. Approve pending hook resolution.

Review: LGTM

wait_for_ci() is clean: 5-min polling, 15s interval, logs progress, handles fetch errors gracefully, returns False on timeout so caller can retry next tick. The merge_pull() JSONDecodeError workaround is correct — Gitea returns HTTP 200 with empty body on success, and api() raises ApiError on the decode failure.

Queue ordering note: PR #1403 (fix/queue-merge-error-surfacing-v2) is also in the merge queue and modifies the same gitea-merge-queue.py section. Both PRs touch merge_pull() and latest_statuses_by_context. If #1403 merges before #1396, no conflict. If #1396 merges first and #1403 is rebased, also fine. But if they land in reverse order without rebase, there may be merge conflicts. Recommend core-devops check the interaction.

core-devops review

LGTM on the overall design — the wait_for_ci() polling is the right fix for the update-then-wait loop. Code is clean, well-commented.

One issue: merge error handling conflict with PR #1417

This PR's merge_pull() catches HTTP 405 and logs a warning, then returns normally (no error raised). process_once() continues and returns 0. On the next tick, the queue picks the same PR again → infinite retry loop on HTTP 405.

PR #1417 (fix(queue): skip PRs with HTTP 403/404/405 merge errors instead of looping) adds MergePermissionError and modifies process_once() to catch it, post a comment on the PR, and return 0 (so next tick tries the next queued PR instead of the same one).

Dependency concern: If this PR merges before #1417, the infinite 405-retry loop returns. If #1417 merges first, this PR's merge_pull() 405 handling is redundant (overridden by MergePermissionError catching in process_once()).

Recommendation: Sequence: merge #1417 first (adds MergePermissionError + process_once handling), then merge this PR (which adds wait_for_ci() + JSONDecodeError fix + if not dry_run guard). Alternatively, land both simultaneously.

The wait_for_ci() and dry_run guard are correct and should land — just needs the MergePermissionError handling from #1417 alongside it.
