⚡ Bolt: [성능 개선] 자격 증명 마스킹 시 문자열 일괄 추가 사용

[seonghobae]

scripts/ci/redact_sensitive_log.py에서 큰 문자열을 순회하며 마스킹할 때, _redact_assignments 함수 내에서 output.append(text[cursor])와 같이 문자별(character-by-character)로 리스트에 추가하는 방식은 거대한 CI 로그 처리 시 O(N^2)의 심각한 메모리 할당 및 복사 오버헤드를 유발합니다.

이를 해결하기 위해 문자열 슬라이싱(text[last_append:cursor])을 사용하여 매치되지 않은 텍스트 블록을 한 번에 리스트에 추가(batch append)하도록 최적화했습니다.

Impact

• 거대한 문자열을 파싱할 때 소요되는 시간이 O(N^2)에서 O(N) 근사치로 대폭 감소합니다.
• output 리스트에 단일 문자 요소가 수십만 개 생성되는 것을 방지하여 메모리 사용량을 크게 줄입니다.
• 기능적으로는 완전히 동일하며 테스트 및 정적 분석(mypy, bandit, interrogate)을 통과했습니다.

👋 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 @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 2 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
