fix(release): parse changelog commits with NUL delimiters - #1847
Conversation
📝 WalkthroughWalkthroughThe release changelog parser now consumes NUL-delimited Git records, validates complete commit fields, and trims commit bodies. The Git command uses matching separators. Tests cover malformed records, embedded control bytes, and actual ChangesRelease changelog parsing
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The parser can still accept malformed Git output, allowing invalid or truncated commit records to enter generated release notes or cause release generation to fail. Merge should wait until strict SHA validation and terminal-NUL validation are added. Possibly related PRs

In `@scripts/build-release-changelog.ts`:
- Around line 443-448: Strengthen SHA validation in the release commit parsing
flow around the malformed-record check before the commits.push call: reject
whitespace and require sha to be exactly 40 hexadecimal characters, or 64 if
SHA-256 support is already intended, without trimming it before validation;
preserve trimmed storage only after validation succeeds. Add a regression case
in the existing build-release-changelog tests covering an invalid SHA.
- Around line 434-435: Update the raw-field parsing near releaseCommits to
reject nonempty output when the original string lacks a terminal NUL, before
accepting the three-field grouping; preserve acceptance of empty output and
properly NUL-terminated records. Add a regression test in the existing
build-release-changelog test cases covering a complete three-field record
without the final NUL.

Summary
git log -z --format=%H%x00%s%x00%BproducerGit commit subjects and bodies may contain the former
0x1fand0x1edelimiters. A landed contributor commit could therefore create synthetic fields or records, make a real change look like release metadata, omit it from generated notes, or fail release generation. NUL cannot occur in Git commit payloads, so the new framing restores an unambiguous, fail-closed producer/parser contract.The impact is release-note integrity and release availability. This does not create package-code execution, credential exposure, or a change to published package contents.
No user-facing configuration or runtime behavior changes, so documentation is not required.
