From 2b430ea3b604e537005b40a5922cb1aaa4998bc7 Mon Sep 17 00:00:00 2001 From: geobelsky Date: Tue, 19 May 2026 13:31:16 +0000 Subject: [PATCH 1/3] perf(extension): lazy-extract bundled npm runtime on Windows (install 30s, not 2-3min) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit User reported v0.1.2 takes 2-3 minutes to install via "Install from VSIX..." on Windows — much slower than previous builds. Root cause is the .vscodeignore fix in PR #141 that started shipping the bundled node_modules/npm/ tree (~3000 small .js files) instead of silently filtering it. The .vsix size stayed the same (~32 MB, npm compresses well), but Cursor's installer creates each file via CreateFileW which on Windows triggers filter drivers (Windows Defender scan, OneDrive sync, third-party AV) per file. 3000 files × ~50 ms per filter-driver round-trip = ~2.5 min install. Fix: ship the bundled runtime in TWO pieces inside the .vsix: - extension/bin/node-runtime/node.exe (expanded, ~72 MB) - extension/bin/node-runtime/npm-bundle.tar.gz (compressed, ~10 MB) Cursor's installer now writes just two large files at install time. The tarball gets extracted lazily on the user's machine when they first enable search mode — via Windows' built-in tar.exe (bundled since Win10 1803 / 2018, present on every supported Cursor target). Trade-off: - Install time: ~2-3 min → ~30 s (huge win for every install/update) - First search-mode-enable: +5-10 s for one-time tar extraction - Users who never enable search mode pay zero cost - Disk after extract: same as before (tarball + expanded files coexist, ~10 MB tarball overhead until reinstall) Files: - .github/workflows/publish-extension.yml — replace `cp -r node-v.../. extension/bin/node-runtime/` with two steps: cp node.exe, then `tar -czf` everything else into npm-bundle.tar.gz. Verify-step REQUIRED list now checks for the tarball instead of npm-cli.js. - extension/src/bundled-runtime.ts (NEW) — ensureBundledNpmExtracted() helper. Idempotent (skip if npm-cli.js already exists). Uses Windows tar.exe via execFileSync. setExtensionPath() module-level cache mirrors the spawn-binary.ts setBundledNode pattern. - extension/src/extension.ts — call setBundledRuntimePath at activation alongside setBundledNode. - extension/src/search-mode.ts — call ensureBundledNpmExtracted() before spawning the binary that runs npm install. Surface extraction errors as a clear toast with "Show output" affordance. - extension/package.json — bump 0.1.2 → 0.1.3. POSIX path unchanged — bundled-runtime.ts is a no-op there since Linux/macOS execute the shebang shim natively without bundled Node. Will VM-validate before flagging green to user.

The extension extracts npm-bundle.tar.gz at user opt-in time (clicking "Enable semantic search" in the sidebar). But CORE search-install.ts is also invoked from contexts where the extension's pre-extract step doesn't run — e.g. a user shelling out `axme-code config set context.mode search` directly from a terminal, or any tooling that invokes the bundled binary without going through the extension UI. Now CORE's resolveNpm() probes for the canonical sentinel (node_modules/npm/bin/npm-cli.js). If missing AND a sibling npm-bundle.tar.gz exists, it shells out to Windows tar.exe to extract it in place. Idempotent — no-op once npm-cli.js is present, no-op on POSIX, no-op when no tarball is shipped (the user installed via curl not via .vsix, so they have system npm anyway). Failures during extraction are swallowed — resolveNpm() will then fall through to its existing npm.cmd-on-PATH fallback, which gives a useful error if neither path works.
