[WRONG BRANCH] fix(release): parse changelog commits with NUL-delimited git log to prevent delimiter injection - #299
Conversation
|
✅ Deterministic PR hygiene checks passed. |
📝 WalkthroughWalkthroughThe release changelog builder now uses NUL-delimited Git records. The parser validates complete SHA, subject, and body groups, trims values, and preserves control bytes. Tests cover trailing separators and malformed records. ChangesRelease changelog parsing
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ⚪ Minimal · up to The changelog parser now uses NUL-delimited records and fails closed on malformed fields; focused tests and typechecking pass. The remaining integration-test gap is bounded and non-blocking, so no actionable merge-blocking risk remains. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Add a producer/parser integration test.
tests/build-release-changelog.test.ts only passes synthetic strings to parseGitLog. Add a temporary Git-repository test that runs the command at scripts/build-release-changelog.ts:467-475, passes its output to parseGitLog, and asserts two records, six NUL-delimited fields, and preservation of \x1f and \x1e.

Superseded by the dev-targeted upstream PR lidge-jun/opencodex#1847, which carries the same core fix plus terminal-NUL enforcement, exact SHA-1/SHA-256 validation, and producer-level integration coverage. Closing this wrong-branch draft to avoid duplicate review. |

Motivation
git logoutput using non-NUL control bytes (\x1f/\x1e) that can legally appear in commit subjects/bodies, allowing a crafted commit to be misparsed and evade coverage checks.Description
