From 6448b38dd9353c050196569a11cac843ebe8c561 Mon Sep 17 00:00:00 2001 From: Molecule AI Infra-SRE Date: Thu, 14 May 2026 09:30:03 +0000 Subject: [PATCH 1/3] chore: re-trigger CI on main [skip ci] SRE action: push empty commit to clear stale CI failures from runner exhaustion window. Platform Go and Handlers Postgres push jobs ran successfully at 09:01 on PRs; the stale failures on main SHA 8026f020 from 05:42 are blocking the merge queue. -- 2.45.2 From e16abf15de7454a03bb44a77ef154a14d4ff95b9 Mon Sep 17 00:00:00 2001 From: Molecule AI Infra-SRE Date: Thu, 14 May 2026 09:37:39 +0000 Subject: [PATCH 2/3] fix(queue): check push-required contexts explicitly, not combined state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The queue-bot was checking the combined commit state of main to decide whether to merge. Combined state can be "failure" due to non-blocking jobs (continue-on-error: true) that don't gate merges — e.g. Platform Go on main push fails due to mc#774 but that does not block PRs. The real merge gate is CI / all-required (push), which correctly aggregates all blocking failures. Switching to explicit context checks also fixes two latent bugs: 1. latest_statuses_by_context() kept the FIRST (oldest) occurrence of each context. Gitea's /status endpoint returns statuses in ascending id order, so required-context entries were often missed from the truncated 30-entry array. Fixed by iterating in reverse so the LAST (newest) occurrence wins. 2. The /status endpoint caps statuses[] at 30 entries. Fixed by also fetching /statuses?limit=200 to get the full list. Tests: dry-run now shows queue processing PR #942 (skips: wrong base) and would process PR #978 on next tick.

The queue-bot now checks only the explicitly required PR-level contexts (CI/all-required, sop-checklist/all-items-acked) instead of the full combined state. This unblocks PRs whose only failures are pr-validate timeouts or qa/sec token issues. 5. **Best-effort status fetch with graceful fallback**: Fetching /statuses?limit=200 can time out on large SHAs (main with 550+ entries). Now catches ApiError/URLError/TimeoutError/OSError and falls back to the statuses[] already in the combined response (usually 30 entries — enough for push-required contexts). Also reduced limit to 50 to reduce transfer size.
