ci: fetch full history before classifying PR changes - #145
Conversation
📝 WalkthroughWalkthroughThe benchmark workflow now fetches complete pull request history before calculating changed files. Tests verify the full-history checkout and the ordering of the diff command before classification. ChangesBenchmark history checkout
Priority: ⬇️ Low Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🔵 Low · up to This change enables long-lived pull requests to classify changed files using complete history. The workflow currently has the intended order, but the contract test could allow a future reordering that breaks classification; tighten the ordering assertion before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert the command order, not only command presence.
selection contains the complete changes job. The independent regular expressions still pass if fetch-depth: 0 moves after git diff or after scripts/classify-ci-changes.mjs. Match the ordered sequence so the test enforces checkout before commit validation, diff, and classification.
Proposed fix
- assert.match(selection, /fetch-depth:\s*0/)
- assert.match(selection, /git diff --no-renames --name-only -z/)

+ selection,

Fixes the change selector for long-lived pull requests.\n\nThe selector previously checked out only two commits, then required the pull request event's base SHA. When that base is older than the merge ref's current parents, the SHA is missing and classification fails before tests run. PR #54 reproduced this with a base seven commits behind current main.\n\nThe selector now fetches complete history, matching the static job. A workflow contract test locks that checkout depth.\n\n## Verification\n\n- Reproduced the missing-base failure from PR #54 run 34410960489.\n- The exact PR #54 diff classifies as static=docs, compare=false, stress=false when both commits are available.\n- CI workflow contract tests pass, 17 tests.\n- Workflow and test formatting pass.\n- Git diff checks pass.\n\nNo changeset is needed because this only changes repository CI tooling.
