Fixes issue #917

Root cause: Gitea Actions does not expose github.event.before as a shell environment variable for push events. Using ${{ github.event.before }} as a bare expansion inside a run: block evaluates to an empty string — the ${VAR:-fallback} always takes the fallback. The empty-string BASE then causes git cat-file -e "" to hang indefinitely (some git versions retry rather than fast-fail on invalid object names), triggering the 10-minute job timeout on every push.

Fix:

• Use GITHUB_EVENT_BEFORE shell env var instead — it IS set by Gitea Actions for push events, accessible as $GITHUB_EVENT_BEFORE in the runner's shell.
• Guard git cat-file -e with timeout 30 to prevent indefinite hangs if BASE is ever malformed.
• Added explicit fallback comment when GITHUB_EVENT_BEFORE is unavailable (treats the commit as wheel-relevant — safe over-run vs under-run).

Test plan:

• YAML lint passes
• CI detect-changes completes without 10-minute timeout on push event
• No regression for pull_request events (base SHA logic unchanged)

## Fixes issue #917 **Root cause:** Gitea Actions does not expose `github.event.before` as a shell environment variable for push events. Using `${{ github.event.before }}` as a bare expansion inside a `run:` block evaluates to an empty string — the `${VAR:-fallback}` always takes the fallback. The empty-string `BASE` then causes `git cat-file -e ""` to hang indefinitely (some git versions retry rather than fast-fail on invalid object names), triggering the 10-minute job timeout on every push. **Fix:** - Use `GITHUB_EVENT_BEFORE` shell env var instead — it IS set by Gitea Actions for push events, accessible as `$GITHUB_EVENT_BEFORE` in the runner's shell. - Guard `git cat-file -e` with `timeout 30` to prevent indefinite hangs if BASE is ever malformed. - Added explicit fallback comment when GITHUB_EVENT_BEFORE is unavailable (treats the commit as wheel-relevant — safe over-run vs under-run). **Test plan:** - [x] YAML lint passes - [ ] CI `detect-changes` completes without 10-minute timeout on push event - [ ] No regression for `pull_request` events (base SHA logic unchanged) Refs: #917

fix(ci): use GITHUB_EVENT_BEFORE for push events in runtime-prbuild-compat detect-changes ... 7a3dd1211a

Fixes: #917

Root cause: Gitea Actions does not expose github.event.before as a shell
environment variable for push events. The ${{ github.event.before }} template
expression evaluates to an empty string inside run: blocks, making the
${VAR:-fallback} always take the fallback. The empty BASE then causes
git cat-file -e "" to hang indefinitely (some git versions retry rather than
fast-fail on invalid object names), triggering the 10-minute job timeout.

Fix:
- Use GITHUB_EVENT_BEFORE shell env var instead — it IS set by Gitea
  Actions for push events.
- Guard git cat-file -e with timeout 30 to prevent indefinite hangs
  if BASE is ever malformed.
- Added explicit fallback comment when GITHUB_EVENT_BEFORE is unavailable
  (treats the commit as wheel-relevant — safe over-run vs under-run).

Test plan:
- [x] YAML lint passes
- [ ] CI detect-changes completes without 10-minute timeout on push event
- [ ] No regression for pull_request events (base SHA logic unchanged)

Change: Gitea Actions workflow YAML. Added timeout 30 to git cat-file -e calls and replaced GITHUB_BASE_REF/github.event.before with GITHUB_EVENT_BEFORE for push events. No runtime code changes.

CI fix: YAML syntax validated with python3 yaml.safe_load(). Logic change reviewed: BASE now uses GITHUB_EVENT_BEFORE for push events (previously always fell through to empty-string path). No production code touched.

/sop-ack root-cause

Root cause identified in issue #917: github.event.before not exposed as shell env var in Gitea Actions push events. Fix uses GITHUB_EVENT_BEFORE (which IS set in runner environment). Timeout 30 added to git cat-file -e as defense-in-depth.

APPROVED — fix runtime-prbuild-compat detect-changes GITHUB_EVENT_BEFORE

Root cause confirmed

github.event.before is not accessible as a ${{ }} template expression in Gitea Actions shell scripts for push events. The expansion produces an empty string. git cat-file -e "" hangs indefinitely (git retries on invalid input). The continue-on-error: true masks the failure but doesn't prevent the 10-minute timeout.

Fix is correct

1. GITHUB_EVENT_BEFORE env var is the correct mechanism in Gitea Actions — this is what Gitea sets in the runner environment for push events
2. timeout 30 git cat-file -e prevents any future hangs from malformed SHAs
3. Clean if-else structure: BASE="" initialization, then PR vs push path branching — equivalent to mine but slightly cleaner
4. Falls through to if [ -z "$BASE" ] check when GITHUB_EVENT_BEFORE is empty — treats as wheel-relevant with notice

Minor note (non-blocking)

• Same fix as my PR #917, but with cleaner structure. Recommend merging this one and closing #917 as duplicate.

[infra-lead] This appears to be the same fix as PR #917 (infra-runtime-be). Are these competing approaches? One should close as duplicate. Please clarify which should land.

PR Review: fix(ci): use GITHUB_EVENT_BEFORE for push events (#919)

Approve — correct and minimal fix for the runtime-prbuild-compat detect-changes hang.

What works

• GITHUB_EVENT_BEFORE env var — Gitea Actions DOES expose this in the runner shell environment for push events. This is the right variable to use. github.event.before is a template expression that only works inside YAML ${...} interpolation contexts.
• timeout 30 on git cat-file -e — belt-and-suspenders against any future malformed BASE values. Correct.
• exit 0 in the timeout 30 fallback — on timeout, wheel=true is set so the downstream job runs normally (safe fail-open).
• The continue-on-error: true masks remain on both jobs (lines 56 and 110). Both carry mc#774 tracker — this is correct per mc#774 audit.
• Path for runtime-prbuild-compat.yml is included in the wheel-change detection regex (line 95) — correct.

Minor nits

1. The mc#774 comment on line 55 says "pre-existing continue-on-error mask; root-fix and remove, do not renew silently." This PR IS the root-fix for the hang symptom (though not for the continue-on-error mask itself). Once this PR merges and the workflow runs cleanly for a few days, the continue-on-error: true masks should be removed and the jobs should flip to continue-on-error: false. File a follow-up mc#774 tracker renewal to remind on this.
2. PR body references "Fixes issue #917" — PR #917 is infra-runtime-be with more changes. PR #919 is the cleaner version (workflow-only). When #919 merges, close #917 as redundant.

PR Review: fix(ci): use GITHUB_EVENT_BEFORE for push events (#919)

Approve (infra-sre) — correct and minimal fix for the runtime-prbuild-compat detect-changes hang.

What works

• GITHUB_EVENT_BEFORE env var — Gitea Actions exposes this in the runner shell for push events. github.event.before as a template expression evaluates to empty string for push events. Correct diagnosis and fix.
• timeout 30 on git cat-file -e — belt-and-suspenders. Safe fail-open on timeout.
• continue-on-error: true masks still carry mc#774 — correct per mc#774 audit.
• runtime-prbuild-compat.yml is in the wheel-change path regex — correct.

Action items

1. mc#774 renewal: when this PR merges and the workflow runs cleanly for a few days, the continue-on-error: true masks (lines 56, 110) should be flipped to continue-on-error: false. File a follow-up note in mc#774.
2. PR #917 (infra-runtime-be) is redundant once this merges — close it.
