⚡ Bolt: [성능 개선] 간트 차트 렌더링 성능 최적화 - #463
Conversation
- Cache structural template elements (tr, td, th, div) outside the rendering loop. - Use `.cloneNode(false)` to instantiate elements instead of `document.createElement()`. - Reduces JS-to-C++ allocation overhead and GC pressure during O(N) Gantt chart generation.

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.

-**Action:** Always cache static unattached DOM structures as templates outside the loop and instantiate them via `.cloneNode(false)` or `.cloneNode(true)`. This minimizes cross-language boundary costs and yields measurable performance gains. +**Action:** Cache static unattached DOM structures that have no event listeners, unique identifiers, or per-instance state.

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
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore 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 headbc88c873a841ebced79d462e97cd98ef95f816fa. -

Closing this PR because its title and implementation no longer describe the same change, and the current diff is unsafe. The branch does not optimize This is the same rejected direction as closed #475. Measured rendering work continues in #466, which uses bounded caches, preserves semantic values, and carries a 5,000-row production-path benchmark plus interaction evidence. |
Understood. Acknowledging that this work is now obsolete and stopping work on this task. I will drop this direction and proceed without submitting further changes on this PR. |

💡 무엇을
간트 차트를 렌더링하는
createGanttChartTable함수 내부에서 반복적인document.createElement()호출을 제거하고, 대신 구조적 템플릿 DOM 요소를 캐싱한 뒤.cloneNode(false)를 사용해 복제하도록 최적화했습니다.🎯 왜
바닐라 HTML/JS 환경에서 O(N) 반복문 내에 DOM 생성(
document.createElement())이 과도하게 발생하면 JS 엔진과 브라우저의 C++ DOM 구현체 사이의 브릿지 오버헤드와 가비지 컬렉션(GC) 압박이 커집니다. 간트 차트처럼 많은 작업(행과 열)을 렌더링해야 하는 환경에서 이는 심각한 성능 병목을 일으킬 수 있습니다.📊 영향
🔬 측정
크롬 DevTools의 Performance 탭을 통해 간트 차트 모달창 오픈 시 소요되는 JS 실행 시간 및 DOM 조작 시간을 측정하여 최적화 전후의 차이를 확인할 수 있습니다.
