From 5461a65aca9f4170efd1a37416e47d8bc6852641 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=E5=8F=B6=E5=85=AC?= Date: Sun, 19 Apr 2026 21:58:55 +0800 Subject: [PATCH 01/14] perf(filesearch): move recursive crawl + fzf index to worker_threads MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Before P1 the recursive @-picker did the fdir crawl and synchronous `new AsyncFzf(...)` construction on the main thread. On 100k-file workspaces that blocked the Ink render loop for 500ms–2s, so pressing `@` felt unresponsive. This change introduces `FileIndexCore` (pure class), `FileIndexWorker` (worker_threads entry), and `FileIndexService` (main-thread singleton that multiplexes search requests and exposes onPartial for future streaming). `RecursiveFileSearch` becomes a thin proxy, preserving the public `FileSearch` contract (and vscode-ide-companion's usage) untouched. The esbuild bundle now emits a self-contained `dist/fileIndexWorker.js` alongside `dist/cli.js`. --- esbuild.config.js | 96 ++-- packages/cli/src/ui/hooks/useAtCompletion.ts | 90 +++- packages/core/src/index.ts | 4 + packages/core/src/utils/filesearch/crawler.ts | 49 +- .../utils/filesearch/fileIndexCore.test.ts | 94 ++++ .../src/utils/filesearch/fileIndexCore.ts | 193 ++++++++ .../utils/filesearch/fileIndexService.test.ts | 101 +++++ .../src/utils/filesearch/fileIndexService.ts | 424 ++++++++++++++++++ .../src/utils/filesearch/fileIndexWorker.ts | 100 +++++ .../core/src/utils/filesearch/fileSearch.ts | 122 +---- 10 files changed, 1115 insertions(+), 158 deletions(-) create mode 100644 packages/core/src/utils/filesearch/fileIndexCore.test.ts create mode 100644 packages/core/src/utils/filesearch/fileIndexCore.ts create mode 100644 packages/core/src/utils/filesearch/fileIndexService.test.ts create mode 100644 packages/core/src/utils/filesearch/fileIndexService.ts create mode 100644 packages/core/src/utils/filesearch/fileIndexWorker.ts diff --git a/esbuild.config.js b/esbuild.config.js index e84b6223bd2..7a7e2e54ce7 100644 --- a/esbuild.config.js +++ b/esbuild.config.js @@ -72,45 +72,65 @@ const external = [ '@teddyzhu/clipboard-win32-arm64-msvc', ]; -esbuild - .build({ - entryPoints: ['packages/cli/index.ts'], - bundle: true, - outfile: 'dist/cli.js', - platform: 'node', - format: 'esm', - target: 'node20', - external, - packages: 'bundle', - inject: [path.resolve(__dirname, 'scripts/esbuild-shims.js')], - banner: { - js: `// Force strict mode and setup for ESM +const commonBundleOptions = { + bundle: true, + platform: 'node', + format: 'esm', + target: 'node20', + external, + packages: 'bundle', + define: { + 'process.env.CLI_VERSION': JSON.stringify(pkg.version), + // Make global available for compatibility + global: 'globalThis', + }, + loader: { '.node': 'file' }, + plugins: [wasmBinaryPlugin, wasmLoader({ mode: 'embedded' })], + write: true, + keepNames: true, +}; + +const mainBuild = esbuild.build({ + ...commonBundleOptions, + entryPoints: ['packages/cli/index.ts'], + outfile: 'dist/cli.js', + inject: [path.resolve(__dirname, 'scripts/esbuild-shims.js')], + banner: { + js: `// Force strict mode and setup for ESM "use strict";`, - }, - alias: { - 'is-in-ci': path.resolve( - __dirname, - 'packages/cli/src/patches/is-in-ci.ts', - ), - '@qwen-code/web-templates': path.resolve( - __dirname, - 'packages/web-templates/src/index.ts', - ), - // Resolve to userland punycode instead of deprecated node:punycode built-in - punycode: require.resolve('punycode/'), - }, - define: { - 'process.env.CLI_VERSION': JSON.stringify(pkg.version), - // Make global available for compatibility - global: 'globalThis', - }, - loader: { '.node': 'file' }, - plugins: [wasmBinaryPlugin, wasmLoader({ mode: 'embedded' })], - metafile: true, - write: true, - keepNames: true, - }) - .then(({ metafile }) => { + }, + alias: { + 'is-in-ci': path.resolve(__dirname, 'packages/cli/src/patches/is-in-ci.ts'), + '@qwen-code/web-templates': path.resolve( + __dirname, + 'packages/web-templates/src/index.ts', + ), + // Resolve to userland punycode instead of deprecated node:punycode built-in + punycode: require.resolve('punycode/'), + }, + metafile: true, +}); + +// The file-index worker runs in its own worker_threads process and must exist +// as a standalone file next to dist/cli.js so that `new URL('./fileIndexWorker.js', +// import.meta.url)` resolves at runtime (the main bundle's import.meta.url is +// dist/cli.js).

Also reorders unsubscribe before posting 'dispose' so the in-process transport's synchronous exit cleanup can't beat the AbortError. - worker.on('error') is wired, converting uncaught worker errors into a normal exit-cleanup path instead of re-throwing on the main process and crashing the CLI. - useAtCompletion gains a monotonic refreshToken in its reducer state and effect deps, so REFRESH re-triggers the worker effect even when the status was already SEARCHING (previously a partial chunk arriving mid-search could not cause a re-run). - Worker 'dispose' now closes parentPort instead of process.exit(0) so in-flight searchResult/searchError messages drain before shutdown. - FileIndexCore.startCrawl preserves the allFiles reference on the cache-hit fallback path to keep concurrent search() iterations stable. - dispose() races transport.terminate() against a 2s timeout so a faulted worker cannot hang shutdown. - handleExit is now idempotent: if dispose() already set disposed=true, a subsequent worker exit won't double-reject pending/readyWaiters. Added regression tests for whenReady-on-dispose rejection and for post-dispose FileIndexService.for() creating a fresh instance. --- packages/cli/src/ui/hooks/useAtCompletion.ts | 21 +++++- .../src/utils/filesearch/fileIndexCore.ts | 12 +-- .../utils/filesearch/fileIndexService.test.ts | 19 +++++ .../src/utils/filesearch/fileIndexService.ts | 73 ++++++++++++++++--- .../src/utils/filesearch/fileIndexWorker.ts | 9 ++- 5 files changed, 113 insertions(+), 21 deletions(-) diff --git a/packages/cli/src/ui/hooks/useAtCompletion.ts b/packages/cli/src/ui/hooks/useAtCompletion.ts index d7282d1a1b4..5862ec9827e 100644 --- a/packages/cli/src/ui/hooks/useAtCompletion.ts +++ b/packages/cli/src/ui/hooks/useAtCompletion.ts @@ -34,6 +34,10 @@ interface AtCompletionState { suggestions: Suggestion[]; isLoading: boolean; pattern: string | null; + // Monotonic counter bumped on every REFRESH so effects depending on state + // can re-run even when `status` and `pattern` stay the same (e.g. REFRESH + // hits while we are already in SEARCHING). + refreshToken: number; } type AtCompletionAction = @@ -51,6 +55,7 @@ const initialState: AtCompletionState = { suggestions: [], isLoading: false, pattern: null, + refreshToken: 0, }; function atCompletionReducer( @@ -76,8 +81,10 @@ function atCompletionReducer( case 'REFRESH': // Re-run the current pattern against a newly-grown snapshot.

Added regression tests: stale-key service is disposed and its `search()` throws AbortError after .gitignore-driven eviction. --- packages/core/src/index.ts | 5 +---- .../utils/filesearch/fileIndexService.test.ts | 3 +++ .../src/utils/filesearch/fileIndexService.ts | 22 ++++++++++++++++++- scripts/prepare-package.js | 5 +++++ 4 files changed, 30 insertions(+), 5 deletions(-) diff --git a/packages/core/src/index.ts b/packages/core/src/index.ts index 9d383afc9b0..503fb1d4600 100644 --- a/packages/core/src/index.ts +++ b/packages/core/src/index.ts @@ -266,10 +266,7 @@ export * from './utils/errorParsing.js'; export * from './utils/errors.js'; export * from './utils/fileUtils.js'; export * from './utils/filesearch/fileSearch.js'; -export { - FileIndexService, - __setIndexTransportFactory, -} from './utils/filesearch/fileIndexService.js'; +export { FileIndexService } from './utils/filesearch/fileIndexService.js'; export * from './utils/formatters.js'; export * from './utils/generateContentResponseUtilities.js'; export * from './utils/getFolderStructure.js'; diff --git a/packages/core/src/utils/filesearch/fileIndexService.test.ts b/packages/core/src/utils/filesearch/fileIndexService.test.ts index c502dff2c8d..5d33d67fdb5 100644 --- a/packages/core/src/utils/filesearch/fileIndexService.test.ts +++ b/packages/core/src/utils/filesearch/fileIndexService.test.ts @@ -139,5 +139,8 @@ describe('FileIndexService', () => { useGitignore: true, }); expect(b).not.toBe(a); + // And — regression test — the stale instance must have been disposed, so + // its worker doesn't linger in INSTANCES keyed under the old fingerprint. + await expect(a.search('a')).rejects.toMatchObject({ name: 'AbortError' }); }); }); diff --git a/packages/core/src/utils/filesearch/fileIndexService.ts b/packages/core/src/utils/filesearch/fileIndexService.ts index 9d2adb8dc0a..cacb45dd6aa 100644 --- a/packages/core/src/utils/filesearch/fileIndexService.ts +++ b/packages/core/src/utils/filesearch/fileIndexService.ts @@ -264,6 +264,19 @@ export class FileIndexService { const key = optionsKey(options); const existing = INSTANCES.get(key); if (existing && !existing.disposed) return existing; + // Before minting a fresh singleton, evict any previous instance keyed + // under a *different* hash for the same `projectRoot`.

The audit correctly called out that this silently breaks useAtCompletion: the hook's catch block swallows `AbortError` as "user pressed ESC" and never dispatches the ERROR state, so a crawlError-driven cascade (where dispose() is called and the next search hits the sync guard) would leave the UI stuck in SEARCHING forever.

Empirical benchmarking on two representative trees refuted the premise: qwen-code (~2700 files) fdir ~25ms vs rg (spawn+IPC) ~140ms node_modules (~48k files) fdir ~640ms vs rg (spawn+IPC) ~1800ms Even though `rg --files` is ~70ms in a shell, the child_process spawn and stdout-pipe overhead from Node dominates for every tree size we tested. Claude Code's speed almost certainly comes from being a native binary with an in-process walker, not from shelling out to ripgrep. The ripgrepCrawler implementation is kept for future re-evaluation on very large trees or different platforms, and is reachable via the `QWEN_FILESEARCH_USE_RG=1` env var. fdir remains the default.

User-reported feedback prompted a re-test on a home-directory-scale target: qwen-code repo (~2700 files) fdir ~25ms rg ~140ms fdir wins project/node_modules (~48k) fdir ~640ms rg ~1800ms fdir wins ~/ home dir (100k-file cap) fdir ~9s rg ~2.5s rg 3-4× wins The slow case is the painful one — a user typing @ at $HOME shouldn't wait 9 seconds while Node's single-threaded walker catches up. On small repos both backends are well below the 200ms loading threshold, so the perceptual cost of rg's spawn overhead is zero.

Normalize to posix first, then strip; guard the filter for `.`/`./`/leading-`./` inputs as defence in depth. Also addresses review feedback: - fileIndexService: an early worker exit left `_state` at `'crawling'`, so a `whenReady()` call arriving after the exit parked in readyWaiters and never settled. `handleExit` now transitions to `'error'` so the state check rejects synchronously. - AppContainer prewarm: guarded on `enableRecursiveFileSearch` so opted-out users don't pay for a full crawl + worker at startup. - FileMessageHandler: added a per-rootPath generation token so an in-flight `initialize()` disposes the stale index instead of re-caching it when `clearFileSearchCache` fires mid-crawl. Regression tests added for all four.

Root cause: `ripgrep --files` is spawned with `cwd: crawlDirectory`, and on Windows the OS holds a handle on that working directory until the child fully exits. If `afterEach` calls `cleanupTmpDir` before the FileIndexService (and its rg subprocess) is disposed, rmdir races the handle release and fails. Three-pronged fix: - `cleanupTmpDir` now passes `maxRetries: 5, retryDelay: 100` to `fs.rm`. Node retries EBUSY/EPERM internally on Windows; half a second is plenty for tens-of-ms handle-release races. This is a blanket safety net for every caller. - `fileIndexService.test.ts` afterEach: `__resetForTests()` runs before `cleanupTmpDir` so the transport is torn down first. - `useAtCompletion.test.ts` afterEach: added the same `FileIndexService.__resetForTests()` call so the hook's in-process worker is disposed before the dir is removed.

Later `vi.mock('fs', …)` declarations in individual test files no longer took effect, so `fs.existsSync()` fell through to the real FS and silently dropped mock directories. Fixed by removing the install from both `test-setup.ts` files and opt-ing in per-test-file (`beforeAll`/`afterAll`) in the three suites that actually exercise the worker-backed filesearch: - `packages/core/src/utils/filesearch/fileIndexService.test.ts` - `packages/core/src/utils/filesearch/fileSearch.test.ts` (also drops live singletons between tests so Windows rmdir doesn't race an open ripgrep child) - `packages/cli/src/ui/hooks/useAtCompletion.test.ts` The two `test-setup.ts` files now carry an explanatory comment so this doesn't regress. 2. CI matrix stuck for ~10h on "Run tests and generate reports" Likely cause: pending `setTimeout` handles keeping the event loop alive past test completion. - `FileIndexService.dispose()` raced `terminate()` against a 2 s `setTimeout` but never cleared the timer on the healthy-exit path — so after every disposal the process held a timer for up to 2 s. Now the terminate() arm clears the timer, and the timer is also `.unref()`'d as a belt-and-suspenders. - `crawlCache` TTL timers (default 30 s) are now `.unref()`'d too. They'd keep vitest workers waiting on exit even after all assertions passed. `clear()` still drops both synchronously between tests, so correctness is unchanged. Verified: - `npx vitest run src/config/config.test.ts -t "should ignore implicit startup"` now passes (was failing before). - Full test suites — core 5925 / 5927, cli 4275 / 4282 (skipped tests pre-existing), vscode-ide-companion 204 / 205 — all green. - Typecheck clean on core + cli.
