⚡ Bolt: [performance improvement] job_store.py의 SQLite PRAGMA journal_mode=WAL 실행 최적화

[seonghobae]

💡 What: JobStore 클래스 내에서 데이터베이스 연결 시마다 PRAGMA journal_mode=WAL 쿼리를 실행하던 것을 초기화 단계에서 최초 1회만 실행하도록 수정했습니다.
🎯 Why: SQLite의 PRAGMA journal_mode=WAL은 데이터베이스 파일별로 영속적으로 저장되므로, 연결을 열 때마다 매번 실행하는 것은 오버헤드입니다.
📊 Impact: 1,000번의 get() 벤치마크 테스트 결과 약간의 성능 향상을 가져오고 불필요한 데이터베이스 쿼리를 줄였습니다.
🔬 Measurement: tests/test_job_store.py의 모든 테스트가 성공하며 커버리지 100%를 달성한 것을 확인했습니다.

👋 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: 29 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

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.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

• Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

• Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

• Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

• Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

• Result: REQUEST_CHANGES

• Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head 69af139cfb51e0634a415771f656192fe7c6d076.

Closing as superseded by #423. The production job_store.py WAL change here is byte-for-byte the same semantic change already owned by #423: set PRAGMA journal_mode=WAL during initialization and remove the per-connection PRAGMA. This branch adds only ad-hoc benchmark scripts plus generated SQLite database artifacts beyond that product delta; those are not durable test/benchmark evidence and should not enter the product tree. Preserve #423 as the single WAL-optimization lane and revalidate it against the then-current owners of job_store.py / usage_metering.py before any merge.
