From 1affe1749719da83dedef0432123cc000ba648b9 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 1 Sep 2026 03:55:38 +0000 Subject: [PATCH] =?UTF-8?q?=E2=9A=A1=20Bolt:=20Refactor=20statSync=20insid?= =?UTF-8?q?e=20sort=20for=20BaselineManager?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 💡 What: Replaced synchronous `statSync()` blocking calls inside the `List.sort` comparator with an asynchronous Schwartzian transform to cache file stats concurrently before sorting. 🎯 Why: `statSync()` causes repeated, blocking disk accesses evaluated $O(N \log N)$ times during sorting. Caching file stats beforehand reduces blocking I/O and reads to $O(N)$. 📊 Impact: Substantially reduces I/O wait times and prevents blocking the main thread when loading baselines across many files. 🔬 Measurement: Run `flutter test test/core/baseline_manager_test.dart` to verify no regressions in report loading logic.
