불필요한 I/O 호출 및 파일 객체 생성을 줄이고 불필요한 정렬 작업을 제거하여 성능을 향상시켰습니다. - `process_ignore_file`에서 불필요한 `.sorted()` 호출을 제거하고 `.any`를 사용하여 제외 규칙 검사 최적화 (O(N log N) 오버헤드 감소). - `process_dir`에서 파일이 제외 목록에 있는지 먼저 확인하여, 제외된 파일에 대한 불필요한 `Path` 객체 생성 및 비용이 높은 `Files.isDirectory`, `Files.isSymbolicLink` I/O 시스템 호출을 방지. - 불필요한 `it.toPath()` 중복 호출 제거. - `.jules/bolt.md`에 성능 관련 주요 학습 내용(Critical Learnings) 추가.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Pull request overview
OpenCode reviewed the current-head mergeability evidence and changed-file flow before approval, then found merge conflicts on the affected path.
Findings
1. HIGH Merge Conflict Guidance - Resolve the PR branch against the latest base branch
- Problem: GitHub reports mergeStateStatus
DIRTYfor this pull request. - Root cause: Branch
bolt-perf-optimization-6262557971577667747cannot be merged cleanly intomaster; the changed-file flow below shows which review/runtime path is blocked by the conflict. - Fix: Merge or rebase the latest
masterintobolt-perf-optimization-6262557971577667747, resolve conflict markers in the PR branch, rerun the focused checks, and push the same branch. - Repair commands:
gh pr checkout 133 --repo ContextualWisdomLab/html4tree
git fetch origin master
git merge --no-ff origin/master # or: git rebase origin/master
git status --short
# resolve files, then git add <resolved-files>
# merge path: git commit
# rebase path: git rebase --continue
git push origin HEAD:bolt-perf-optimization-6262557971577667747
# rebase path only: git push --force-with-lease origin HEAD:bolt-perf-optimization-6262557971577667747- Regression test: Keep OpenCode approval gated on mergeability so model-output failures cannot approve a conflicted PR.

💡 What:
디렉토리 크롤링 과정(
process_dir)과 무시할 파일 목록 생성(process_ignore_file) 로직의 성능을 최적화했습니다.🎯 Why:
기존 코드에서는 디렉토리를 순회할 때 모든 파일에 대해
Path객체를 생성하고 비용이 높은 파일 시스템 호출(isDirectory,isSymbolicLink)을 수행한 뒤에야 제외(exclude) 목록에 포함되었는지 확인했습니다. 또한 제외 목록을 구성할 때 불필요하게 정렬(sorted())을 수행하여 성능 저하가 발생했습니다.📊 Impact:
제외된 파일이 많은 디렉토리(예:
node_modules등)나 파일 개수가 매우 많은 디렉토리(O(N log N) 정렬 비용 감소)를 처리할 때 실행 시간과 객체 생성(GC 부하)이 크게 감소합니다.🔬 Measurement:
100% 테스트 커버리지를 유지하면서 (
jacocoTestReport확인 완료) 기존 기능이 동일하게 동작하는지 확인했습니다. 테스트 코드를 통해 기능 손실이 없음을 보장합니다.PR created automatically by Jules for task 6262557971577667747 started by @seonghobae
