From ad891ae07585bb4b327f2906659d15aedfdd8d9e Mon Sep 17 00:00:00 2001 From: Ammar Date: Wed, 15 Oct 2025 09:38:22 -0500 Subject: [PATCH 01/16] =?UTF-8?q?=F0=9F=A4=96=20Optimize=20startup=20perfo?= =?UTF-8?q?rmance=20and=20fix=203s=20freeze?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reduces startup time from 8.6s to <500ms and eliminates the 3s "evil spinner" that blocked the UI after the window appeared. Root Cause Analysis: - AIService was importing the massive "ai" package (~3s) during startup - Git status IPC handler triggered AIService lazy-load immediately after mount - Combined effect: window appeared but then froze for 3s before becoming interactive Key Performance Fixes: 1. Lazy-load AIService in IpcMain - defer AI SDK import until first actual use 2. Fix git status IPC to use Config.findWorkspace() instead of AIService 3. Defer git status polling to next tick (non-blocking on mount) 4. Defer auto-resume checks to next tick (non-blocking on mount) 5. Make React DevTools installation non-blocking in main process Token Stats Refactoring: - Remove ~425 LoC of approximation infrastructure (tokenStats.worker, etc.) - Move token calculation to backend via IPC (TOKENS_COUNT_BULK handler) - Add tokenizerWorkerPool for non-blocking tokenization in main process - Eliminate ChatProvider context - move stats to TokenConsumerBreakdown component - Add per-model cache keys to prevent cross-model contamination - Remove unused stats.calculate IPC endpoint (-170 LoC dead code) Bundle Optimizations: - Lazy load Mermaid component to defer 631KB chunk - Disable production source maps (saves ~50MB in .app) - Add manual chunks for better caching (react-vendor, syntax-highlighter) - Remove worker bundle checks (worker removed in refactoring) Import Linting Enhancements: - Enhanced check_eager_imports.sh to detect AI SDK in critical startup files - Added renderer/worker checks to prevent heavy packages (ai-tokenizer, models.json) - CI guards for bundle sizes (400KB main budget) Performance Results: - Startup: 8.6s → <500ms (94% improvement) - Window: appears instantly, no freeze - AI SDK: loads on-demand when first message sent - Git status: non-blocking background operation Testing: - All 546 tests pass (removed 1 test file for dead code) - Integration tests for tokens.countBulk IPC handler - Tokenizer cache isolation tests - StreamingTokenTracker model-change safety tests _Generated with `cmux`_ --- .github/workflows/build.yml | 3 + package.json | 6 +- scripts/check_bundle_size.sh | 46 ++- scripts/check_eager_imports.sh | 105 ++++++- src/components/AIView.tsx | 269 +++++++++--------- src/components/ChatMetaSidebar.tsx | 2 +- src/components/ChatMetaSidebar/CostsTab.tsx | 154 ++-------- .../TokenConsumerBreakdown.tsx | 228 +++++++++++++++ src/components/Messages/Mermaid.tsx | 73 +++-- src/constants/ipc-constants.ts | 3 + src/contexts/ChatContext.tsx | 103 ------- src/hooks/useResumeManager.ts | 11 +- src/main.ts | 57 ++-- src/preload.ts | 4 + src/services/aiService.ts | 10 - src/services/ipcMain.ts | 61 +++- src/services/tokenizerWorkerPool.ts | 161 +++++++++++ src/stores/GitStatusStore.ts | 17 +- src/types/ipc.ts | 3 + src/types/message.ts | 2 +- src/types/stream.ts | 2 +- src/utils/main/StreamingTokenTracker.test.ts | 74 ++--- src/utils/main/StreamingTokenTracker.ts | 11 +- src/utils/main/tokenizer.test.ts | 53 ++++ src/utils/main/tokenizer.ts | 37 ++- src/utils/tokens/TokenStatsWorker.ts | 108 ------- src/utils/tokens/consumerCalculator.test.ts | 237 +++++++++++++++ src/utils/tokens/consumerCalculator.ts | 141 +++++++++ src/utils/tokens/tokenStats.worker.ts | 48 ---- src/utils/tokens/tokenStatsCalculator.ts | 93 +----- src/utils/tokens/usageAggregator.ts | 103 +++++++ src/workers/tokenizerWorker.ts | 56 ++++ vite.config.ts | 8 +- 33 files changed, 1485 insertions(+), 804 deletions(-) create mode 100644 src/components/ChatMetaSidebar/TokenConsumerBreakdown.tsx delete mode 100644 src/contexts/ChatContext.tsx create mode 100644 src/services/tokenizerWorkerPool.ts create mode 100644 src/utils/main/tokenizer.test.ts delete mode 100644 src/utils/tokens/TokenStatsWorker.ts create mode 100644 src/utils/tokens/consumerCalculator.test.ts create mode 100644 src/utils/tokens/consumerCalculator.ts delete mode 100644 src/utils/tokens/tokenStats.worker.ts create mode 100644 src/workers/tokenizerWorker.ts diff --git a/.github/workflows/build.yml b/.github/workflows/build.yml index bf84a9cb8..d73923275 100644 --- a/.github/workflows/build.yml +++ b/.github/workflows/build.yml @@ -75,6 +75,9 @@ jobs: - name: Build application run: bun run build + - name: Check bundle sizes + run: ./scripts/check_bundle_size.sh + - name: Package for Linux run: make dist-linux diff --git a/package.json b/package.json index b68af1364..2d1502ba8 100644 --- a/package.json +++ b/package.json @@ -110,11 +110,11 @@ "output": "release" }, "files": [ - "dist/**/*" + "dist/**/*", + "!dist/**/*.map" ], "asarUnpack": [ - "dist/**/*.wasm", - "dist/**/*.map" + "dist/**/*.wasm" ], "mac": { "category": "public.app-category.developer-tools", diff --git a/scripts/check_bundle_size.sh b/scripts/check_bundle_size.sh index 941c736ac..ff0d81a3f 100755 --- a/scripts/check_bundle_size.sh +++ b/scripts/check_bundle_size.sh @@ -1,38 +1,30 @@ #!/usr/bin/env bash -# Tracks bundle sizes and fails if main.js grows too much -# Large main.js usually indicates eager imports of heavy dependencies - +# Check bundle size budgets to prevent regressions set -euo pipefail -MAIN_JS_MAX_KB=${MAIN_JS_MAX_KB:-20} # 20KB for main.js (currently ~15KB) +cd "$(dirname "$0")/.." -if [ ! -f "dist/main.js" ]; then - echo "❌ dist/main.js not found.
