⚡ Bolt: 정적 문자열 및 SHA-256 연산 최상위 레벨 추출 최적화 - #297
Conversation
- `process_dir` 내에서 매번 계산되던 `cssContent`, `styleHash`, `css`를 파일 최상위 레벨 프로퍼티로 이동 - 메모리 할당 및 무거운 해시 암호화 연산(`MessageDigest.getInstance`) 반복 수행 방지 - JaCoCo 100% 테스트 커버리지 유지를 위해 `MainTest.kt`에 `testTopLevelCssProperties` 테스트 추가 - `.jules/bolt.md`에 성능 최적화 관련 학습 내용 기록

👋 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. |

the exact CSS text emitted inside the <style> element, including its newline and
whitespace formatting; either construct the hashed value as the complete
<style>${cssContent}</style> body or otherwise reuse the same rendered style
content to keep the hash and output identical.

styleHash가 실제 <style> 본문을 해시하도록 수정하세요.
현재 두 값의 SHA-256 해시가 다릅니다. <style> 내부의 개행과 공백을 포함한 실제 본문을 해시하거나, <style>${cssContent}</style>로 구성하세요.

💡 What
html4tree/main.kt의process_dir함수 내부에 정의되어 있던cssContent,styleHash,css변수들을 파일 레벨(top-level) 프로퍼티로 추출했습니다.MainTest.kt에testTopLevelCssProperties테스트 케이스를 추가했습니다..jules/bolt.md에 관련 학습 내용을 기록했습니다.🎯 Why
process_dir함수는 디렉토리를 순회하며 재귀적으로 (또는 루프 내에서) 호출됩니다.cssContent,css)이 새로 메모리에 할당되었습니다.MessageDigest.getInstance("SHA-256"))이 수행되어 심각한 CPU 및 메모리 낭비(병목)가 발생하고 있었습니다.📊 Impact
