Summary

  • Stop checking out the floating main tip in pr-auto-rebase.yml.
  • Resolve github.workflow_sha, require a 40-character SHA, and check out only that commit.
  • Keep the old canonical_ref input as an ignored compatibility field.
  • Do not change runner groups, required check names, or release STOP legs. This pull request is not merged.

Test

  • tests/test_pr_auto_rebase_source_pin.py and the existing fix-scheduler pin tests: 9 passed.

Summary by CodeRabbit

  • 보안 및 안정성
    • PR 자동 리베이스 워크플로가 검증된 저장소와 커밋에서만 실행되도록 확인 절차를 강화했습니다. 검증에 실패하면 작업이 중단됩니다.
    • canonical_ref는 폐기된 호환성 입력으로 유지되며, 체크아웃 소스 선택에는 사용되지 않습니다.

The scheduler checked out the floating main tip, so the code that ran could
diverge from the workflow GitHub loaded. Validate a 40-character workflow SHA
and check out only that commit. The old canonical_ref input is ignored.

📝 Walkthrough

자동 리베이스 워크플로는 호출 저장소와 github.workflow_sha를 검증한 뒤 해당 SHA를 체크아웃합니다. 체크아웃한 커밋과 워크플로 파일도 확인하며, 테스트는 이 검증 순서와 계약을 검사합니다.

Changes: 신뢰된 워크플로 소스

Layer / File(s) Summary
호출 출처 및 SHA 검증
.github/workflows/pr-auto-rebase.yml, tests/test_pr_auto_rebase_source_pin.py
canonical_ref는 기본값이 빈 문자열인 무시되는 호환성 입력으로 남습니다. 워크플로는 호출 저장소와 40자리 소문자 16진수 github.workflow_sha를 체크아웃 전에 검증합니다. 테스트는 출처 검증과 입력 사용 여부를 확인합니다.
체크아웃 및 소스 확인
.github/workflows/pr-auto-rebase.yml, tests/test_pr_auto_rebase_source_pin.py
체크아웃은 검증된 저장소와 SHA를 사용합니다. 후속 단계는 체크아웃 커밋이 SHA와 일치하는지, 예상 파일이 존재하고 심볼릭 링크가 아닌지 확인합니다. 테스트는 해당 검증을 확인합니다.

Merge Risk: 🟡 Moderate · up to 5fccd

The auto-rebase job can run scheduler code from the calling branch instead of the trusted called workflow version, and it does so with write credentials. Source pinning should be corrected before merging.

호출 워크플로가 아닌 실행 중인 재사용 워크플로의 SHA를 사용하세요.

같은 저장소의 브랜치에서 @main의 재사용 워크플로를 호출하면 github.workflow_sha는 호출자 워크플로의 커밋을 가리킵니다. 현재 코드는 그 커밋을 체크아웃합니다. 해당 커밋에 예상 파일이 있으면 이후 SHA 검사와 파일 검사도 통과합니다. 그 결과, 검증하려는 재사용 워크플로와 다른 버전의 scripts/ci/pr_auto_rebase.py가 쓰기 자격 증명을 사용하는 단계에서 실행될 수 있습니다. job.workflow_sha를 사용하고 job.workflow_repository와 job.workflow_file_path도 예상 소스와 대조하세요. 테스트의 SHA 출처 단언도 함께 수정하세요.

Pull request overview

OpenCode reviewed the current-head product diff. Coverage is a separate gate.

Changed files

  • .github/workflows/pr-auto-rebase.yml — GitHub Actions review job
  • tests/test_pr_auto_rebase_source_pin.py — regression suite

Changed behavior

Findings

No source-backed product finding is synthesized from the coverage gate. A coverage miss belongs in the status comment.

  • Head SHA: 5fccd553a2665cc2e4604fd37429a93432864794
  • Workflow run: 38688926378
  • Workflow attempt: 1
  • Coverage gate: failure

Review outcome

Coverage is a gate, not the review. This body reviews the changed product files.
