From afaf0a1e54f63840009abb8b8460d755459b578f Mon Sep 17 00:00:00 2001 From: core-devops Date: Mon, 11 May 2026 15:15:58 -0700 Subject: [PATCH] feat(ci): status-reaper compensates Gitea hardcoded-(push)-suffix on schedule-triggered operational workflow failures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause (verified via runs 14525 + 14526): Gitea 1.22.6 emits commit-status context as / (push) for ANY workflow run on the default-branch HEAD, REGARDLESS of the trigger event. Schedule- and workflow_dispatch-triggered runs therefore paint main red via a fake-push status. No upstream fix in 1.23-1.26.1 (sibling a6f20db1 research; internal#80 RFC). Design — Option B (b2 cron-based compensating-status POST): workflow_run is NOT supported on Gitea 1.22.6 (verified via modules/actions/workflows.go enumeration); cron is the only event-shaped option that fires reliably. Every 5min, .gitea/workflows/status-reaper.yml runs a stdlib + PyYAML scanner that: 1. Walks .gitea/workflows/*.yml. Resolves each workflow_id from top-level 'name:' (else filename stem). Fails LOUD on name-collision OR '/' in name (would break ' / ' context parsing downstream). Classifies each by 'push:' trigger presence (str / list / dict on: shapes all handled). 2. Reads main HEAD's combined commit status. 3. For each failure-state context ending ' (push)': - parses ' / (push)'; - skips if workflow not in scan map (conservative); - preserves if workflow has push: trigger (real defect); - else POSTs state=success with the same context to /repos/{o}/{r}/statuses/{sha}, with a description that documents the workaround. Safety: - Only failure-state contexts whose suffix is ' (push)' are compensated. Branch_protections required checks on main (Secret scan, sop-tier-check) have ' (pull_request)' suffix — UNREACHABLE from this code path. Verified 2026-05-11 + test test_reap_required_check_pull_request_suffix_never_touched. - publish-workspace-server-image has a real push: trigger → PRESERVED. mc#576's docker-socket failure stays visible as intended. Explicit test fixture. - api() raises ApiError on non-2xx + JSON-decode failure per feedback_api_helper_must_raise_not_return_dict. Pre-fix 'soft-fail' would silently paint main green via omission. Persona: claude-status-reaper (Gitea uid 94, write:repository) — provisioned 2026-05-11 21:39Z by sub-agent aefaac1b. Token under secrets.STATUS_REAPER_TOKEN (no other write surface touched). Acceptance (post-merge verify, Step-5): Trigger one class-O workflow via workflow_dispatch (e.g. sweep-cf-tunnels). Observe reaper compensate the resulting (push)-suffix failure on the next 5-min tick. Real push-triggered failures (publish-workspace-server-image) MUST still red main. Removal path: Drop this workflow + script + tests when Gitea is upgraded to >= 1.24 with a fix for the hardcoded-suffix bug, OR when an upstream patch lands (internal#80 RFC). Tracked in post-merge audit issue.
