feat(release): generate conventional-commit release notes (epic 005 T013/T014) - #55
Merged
Conversation
…013/T014) Test-first (Constitution I): fixture test written and confirmed red before release-notes.sh existed, green after. Groups commit subjects by feat/fix/docs/chore prefix into markdown sections, with a fallback bucket for anything else, and a full-history fallback for the first release (no previous tag). No bash arrays -- macOS's default /usr/bin/env bash resolves to 3.2, which raises "unbound variable" on empty-array expansion under set -u; buckets are plain temp files instead. Self-review (pr-review-toolkit:code-reviewer) caught two real issues, both fixed: Conventional Commits' `!` breaking-change marker (feat!:, fix(scope)!:) was falling into the fallback bucket instead of grouping with its type; and the first-release fallback path had no `--` separator, so a tag name colliding with a working-tree path would make git treat the argument as ambiguous and fail.

Reviewer's GuideAdds a fixture-based test harness and a new release-notes generator script that derives a commit range from tags, groups conventional commits into markdown sections, and handles first-release and breaking-change edge cases, while updating the CI release-versioning spec tasks to reflect completion of T013/T014.

Re-trigger cubic
coderabbitai: validate current_tag against the same strict SemVer regex validate-release-tag.sh (T005) already enforces in the real pipeline -- this script is also runnable standalone, so don't trust an un-validated tag to reach git log unchecked. Also add a check_not_contains assertion that breaking-change commits don't also land in the fallback bucket. cubic-dev-ai: bucket writes used echo, which interprets backslash escapes under xpg_echo -- switched to printf throughout. The "message present" test assertions used substring matching, which can't detect a failed prefix-strip (the original subject's tail is a substring of the unstripped line too) -- converted to exact full-bullet-line matching across the whole file, not just the two cases originally flagged, for consistency. Declined: wiring the fixture suite into make test/ci.yml (pre-existing gap shared by T005/T006/T011's suites too, not specific to this task); extracting the case prefix patterns into a shared regex matcher (stylistic, current patterns already precisely verified correct); explicit exit-status handling around previous-release-tag.sh's call (already correctly handled by set -e, verified empirically).

Declining: this is already handled correctly by
Declining: stylistic, and the current case patterns were already precisely verified correct during self-review (near-misses like "feature:", "refactor:", "featuring stuff" are all correctly rejected). Rewriting to a regex-based matcher risks introducing a new correctness bug for a maintainability gain that's marginal at this scale (4 known types). |
