Problem

Review on the five sibling PRs (getstream-go#164 and friends) found three defects in the hardening that merged here first, in #288.

  1. The guarded lookups read a failed call as "nothing to release". In steady state nums holds exactly one number, the pending release. One 502 on it warns, continues, and the loop ends empty, so the step reports no pending release, release-pr opens a second Release PR on top of the untagged one, and nothing is ever tagged. Aborting was wrong; answering "nothing pending" when the answer is unknown is worse.
  2. release-pr gated fail-open. !cancelled() && ... pending != 'true' runs the job when detect fails before writing its output, because an empty string is not 'true'. That produces the same duplicate Release PR.
  3. The per-PR jq lost its merged_at check. merge_commit_sha is populated on closed-unmerged PRs too, with GitHub's speculative test-merge commit. Verified live: getstream-go#156 is closed, not merged, still carries autorelease: pending, and its merge_commit_sha is not on main and never will be.

Solution

  • A lookup_failed flag. If either call fails and no candidate was found, the step reports pending=true and stands down rather than releasing on a guess.
  • release-pr gates on needs.detect.outputs.pending == 'false', which is fail-closed for failed, skipped and cancelled alike. The duplicated event and ref guard goes with it.
  • merged_at != null is back in the per-PR filter, as defence in depth behind the listing filter.
  • A stuck release is announced once per sha on its own Release PR, since an annotation and a step summary are both only visible to someone who already opened the run. detect takes pull-requests: write for that.

The step is again identical to the other five.

How to verify

Stubbing gh, the five paths through the branch:

scenario pending ready
nothing pending false false
pending at this commit true true
pending at another sha true false
listing call fails true false
candidate call fails true false

The last two are the fix: unknown stands down instead of releasing.

Summary by CodeRabbit

  • Bug Fixes
    • Release processing now runs only when pending-release status is confirmed.
    • Unavailable or failed status checks no longer trigger release processing.
    • Release candidates are limited to merged pull requests targeting the appropriate branch.
    • Stuck releases now receive a single, non-duplicated comment on the related pull request.

Carries the review outcome from the five sibling PRs back to py, which merged first. The guarded lookups read a failed call as nothing to release, release-pr gated fail-open on !cancelled(), and the per-PR jq had lost its merged_at check, which matters because closed-unmerged PRs keep a speculative merge_commit_sha.

📝 Walkthrough

Walkthrough

The release workflow now treats failed release lookups as unknown, accepts only merged release candidates, gates processing on confirmed state, and deduplicates comments for stuck releases.

Changes

Release detection reliability

Layer / File(s) Summary
Candidate discovery and permissions
.github/workflows/release.yml
The detect job can write pull-request comments. Listing failures set lookup_failed and produce an unknown result.
Release candidate validation and gating
.github/workflows/release.yml
Candidate pull requests must be merged before their merge commits are accepted. Failed lookups block a confirmed no-pending result. release-pr runs only when pending equals false.
Deduplicated stuck-release comments
.github/workflows/release.yml
The workflow checks for an existing marker before posting a stuck-release comment to the specified repository. Comment failures produce a warning.

Release creation can proceed when pending-release status is unknown, risking duplicate Release PRs. Comment retries can also create duplicate stuck-release notices. Resolve these paths before merging.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not treat a comment-list failure as an empty comment list.

If gh api .../comments fails, || echo "" makes seen empty. The marker check then posts a new comment. A rerun can create duplicate stuck-release comments for the same SHA.

Handle the API failure separately. Emit a warning and skip the comment when the existing-comment lookup fails.

Proposed fix
-            seen="$(gh api "repos/${GITHUB_REPOSITORY}/issues/${num}/comments" --paginate --jq '.[].body' || echo "")"
-            if ! printf '%s' "$seen" | grep -qF "$marker"; then
+            if ! seen="$(gh api "repos/${GITHUB_REPOSITORY}/issues/${num}/comments" --paginate --jq '.[].body')"; then
+              echo "::warning::Could not list comments on #${num}."
+            elif ! printf '%s' "$seen" | grep -qF "$marker"; then

detect never checks the repository out, so gh pr comment had no git remote to infer the base repo from and would have failed behind its own || guard. Matches the fix already on the five sibling branches.

🟠 Major · Block release creation after any candidate lookup failure. · release.yml:117-122

.github/workflows/release.yml:117-122
🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Block release creation after any candidate lookup failure.

The loop continues after a failed candidate lookup. If a later candidate returns a SHA equal to HEAD_SHA, the current condition skips the lookup_failed branch, leaves pending=false, sets ready=true, and allows release creation despite incomplete detection.

Check lookup_failed before accepting any candidate SHA.

Proposed fix
-          if [ -z "$sha" ] && [ "$lookup_failed" = true ]; then
+          if [ "$lookup_failed" = true ]; then
