Summary

The managed post-merge hook ran bun run postmerge on every contributor machine after every merge — executing whatever the just-pulled commits put in package.json. There is no way to keep the feature without keeping that auto-executed-code path, so the hook is removed outright.

  • package.json drops the postmerge script; scripts/post-merge.sh and scripts/build-gui-if-changed.ts are deleted.
  • setup-hooks.ts no longer installs hooks. It now also retires an already-installed post-merge shim by exact content match (same mechanism as the retired pre-push shim), so existing contributors lose the vector on their next setup run.
  • CONTRIBUTING.md, the eight localized docs-site contributing pages, and structure/ops/docs-and-release.md describe the retirement and point at bun run build:gui for a manual dashboard rebuild after gui/ changes.

Verification

  • bun test tests/ci-workflows/setup-hooks.test.ts — 9 pass / 1 skip (platform), covering shim retirement under LF and CRLF, custom-hook preservation, configured hooksPath, and linked worktrees.
  • bun run typecheck — clean.

Checklist

  • Base is dev
  • Tests updated for the new behavior
  • Docs updated (8 locales)

Summary by CodeRabbit

  • Documentation

    • Updated contributor guides to explain that hook setup removes unchanged managed pre-push and post-merge hooks while preserving custom hooks.
    • Guides clarify that validation can be run manually and that changes to the GUI may require an explicit rebuild after merging.
  • Behavior Changes

    • Hook setup no longer installs or runs the managed post-merge hook. Validation no longer runs automatically on every push.

📝 Walkthrough

Walkthrough

The repository removes automatic GUI rebuilding after merges and retires the managed post-merge hook. Hook setup removes matching legacy hooks and preserves custom hooks. Tests and contributor documentation reflect the updated behavior.

Changes

Post-merge hook retirement

Layer / File(s) Summary
Remove post-merge automation and retire legacy hooks
package.json, scripts/build-gui-if-changed.ts, scripts/post-merge.sh, scripts/setup-hooks.ts
The postmerge command, GUI change-detection script, and post-merge shim are removed. Hook setup retires matching managed pre-push and post-merge hooks, preserves custom hooks, and reports retirement errors.
Test hook retirement
tests/ci-workflows/setup-hooks.test.ts
Tests cover fresh setup, legacy shim removal with LF and CRLF endings, custom-hook preservation, retirement after a pre-push processing error, configured hook directories, and linked worktrees.
Update hook setup guidance
CONTRIBUTING.md, docs-site/src/content/docs/*/contributing.md, structure/ops/docs-and-release.md
Contributor guidance describes retiring both matching managed hooks. It directs contributors to run bun run build:gui after merges that change gui/ sources.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to d091c

The hook retirement works for the original shim, but the contributor guidance and failure reporting still need correction, and the new test may fail in privileged Linux environments. Resolve these issues before merging.

리뷰 · 우선순위 58 / 80

이 풀리퀘스트는 바탕이 dev예요. 머지가 끝난 뒤 자동으로 돌아가던 post-merge 훅을 빼요.

그 훅은 bun run postmerge를 실행했어요. postmerge는 package.json에 적힌 스크립트예요. 방금 받은 커밋이 그 스크립트를 바꾸면, 기여자 컴퓨터가 그 코드를 바로 실행해요. 대시보드를 다시 짓는 일과 이 자동 실행을 같이 둘 수 없어서, 훅을 설치하는 코드를 통째로 뺐어요.

같이 빠지는 것은 scripts/post-merge.sh, scripts/build-gui-if-changed.ts, 그리고 package.json의 postmerge 스크립트예요.

bun run setup:hooks는 이제 훅을 깔지 않아요. 이미 깔린 옛 pre-push와 post-merge는 줄바꿈을 맞춘 뒤 내용이 저장본과 같을 때만 지워요. 사람이 고쳐 둔 훅은 그대로 둬요. post-merge 해시는 지금 dev의 scripts/post-merge.sh와 같은 값이에요.

화면을 다시 만들 때는 bun run build:gui를 직접 실행하라고 적어 두었어요. types.ts와 config.ts는 이 글이 건드리지 않아요.

라인 - scripts/setup-hooks.ts 48–62행 — 옛 훅은 bun run setup:hooks를 다시 실행한 컴퓨터에서만 지워져요. 그대로 두면 훅은 계속 bun run postmerge를 불러요. 지금은 그 스크립트가 package.json에 없어서 실행이 실패하고, 훅은 그 실패를 무시해요. 나중에 같은 이름 스크립트가 다시 들어오면, 셋업을 안 돌린 컴퓨터는 머지할 때마다 그 스크립트를 실행해요.

라인 - tests/ci-workflows/setup-hooks.test.ts 140–166행 — core.hooksPath 검사와 워크트리 검사는 post-merge 파일을 만들어 두지 않은 채 없다고만 확인해요. 기본 훅 폴더에서 지우는 검사(119–126행)는 있어요. 공유 훅 폴더에 깔린 옛 post-merge가 지워지는지는 이 두 검사가 보여 주지 않아요.

메인테이너의 판단이 필요한 지점

이미 훅을 깔아 둔 사람에게 문서로 "setup을 한 번 더 실행해 달라"고 알리는 것으로 충분한지 정해 주세요. 안내를 안 본 컴퓨터에는 자동 실행이 남아요.

열린 #5766은 공유 core.hooksPath에 이 저장소 훅을 설치하지 말자는 글이에요. 이 글은 설치 자체를 없애서, #5766의 설치 거부와 겹쳐요. 이 글은 공유 폴더라도 내용이 같은 옛 훅은 지워요. #5766을 닫을지, 지우는 동작만 남기고 다시 맞출지 정해 주세요.

이 커밋의 CI 런은 @lidge-jun 이 취소해서, 테스트 잡이 설치 단계에서 멈췄어요.

너의 추천

방향은 맞아요. 바탕은 dev예요. 이대로 머지하면 좋겠어요.

공유 훅 폴더에 옛 post-merge를 넣어 두고 지워지는 검사를 하나 더하면 좋겠어요. #5766은 이 글 다음이면 설치 거부가 할 일이 없어요. 닫는 쪽을 추천해요. 셋업을 다시 돌리라는 안내는 예전 pre-push를 걷어 낼 때와 같은 방식이라, 그 방식으로 가도 돼요.

Addressed in 4d406c57e11: the configured-hooksPath test now installs a stale post-merge shim into the shared directory and asserts setup removes it (previously it only covered pre-push). bun test tests/ci-workflows/setup-hooks.test.ts: 9 pass, 1 platform skip.

Comment thread scripts/setup-hooks.ts Outdated
Comment thread tests/ci-workflows/setup-hooks.test.ts
The managed post-merge hook ran bun run postmerge on every contributor's
machine after every merge, executing whatever the just-pulled commits
put in package.json. There is no way to keep the feature without
keeping that auto-executed-code path, so the hook is removed outright:

- package.json drops the postmerge script and both hook files
  (post-merge.sh, build-gui-if-changed.ts) are deleted.
- setup-hooks.ts no longer installs hooks at all; it now also retires an
  already-installed post-merge shim by exact content match, the same
  way the retired pre-push shim is handled, so existing contributors
  lose the vector on their next setup run.
- CONTRIBUTING.md, the eight localized docs-site contributing pages,
  and structure/ops/docs-and-release.md describe the retirement and
  point at bun run build:gui for a manual dashboard rebuild.
- The setup-hooks test covers shim retirement for both line endings,
  custom-hook preservation, and no-hook fresh installs.
The configured-hooksPath case only placed a stale pre-push. A post-merge shim copied into a shared directory keeps executing pulled code in every repo that resolves it, so the test now installs one and asserts setup removes it.
A failed read or unlink of pre-push aborted the script before the post-merge retirement ran, leaving the shim that executes pulled code in place. Each retirement now warns and continues.

리뷰 반영 확인: 요청하신 검사는 f478ed3575에 이미 있습니다 — 공유 core.hooksPath에 옛 post-merge 심을 두고 setup이 그 디렉터리에서 제거하는지 확인하는 테스트입니다(관리형 훅이 공유 폴더에 남으면 모든 저장소에서 pulled code가 계속 실행되므로). 머지 순서 관련해서는 #5766이 이 PR 뒤에 오면 해당 거부 코드가 할 일이 없는 점도 동의합니다.

Reviewed exact head 67c55f1. The retirement is content-addressed, preserves custom and symlinked hooks, handles configured/shared hooks paths, and still attempts post-merge cleanup after an earlier failure. Focused setup-hooks regression suite passed 11/11 under CPUQuota=200%, MemoryMax=4G, MemorySwapMax=0, TasksMax=128.
