Add n/prefer-node-protocol rule and autofix all bare builtin imports
to use the node: prefix. Simplify the simple-import-sort builtins
pattern to just ^node: since all imports now use the prefix.
Add eslint-plugin-simple-import-sort to enforce consistent import ordering:
- Node.js builtins first
- External packages second
- Relative imports last
- Named imports sorted alphabetically within each statement
Update all packages from zkochan/packages to their latest major versions
and exclude them from minimumReleaseAge requirement. This includes
updating catalog entries, adapting to breaking API changes (default
exports replaced with named exports, sync functions renamed with Sync
suffix), and updating type declarations.
## Summary
Replace individual `.mpk` (MessagePack) files under `$STORE/index/` with a single SQLite database at `$STORE/index.db` using Node.js 22's built-in `node:sqlite` module. This reduces filesystem syscall overhead and improves space efficiency for small metadata entries.
Closes#10826
## Design
### New package: `@pnpm/store.index`
A new `StoreIndex` class wraps a SQLite database with a simple key-value API (`get`, `set`, `delete`, `has`, `entries`). Data is serialized with msgpackr and stored as BLOBs. The table uses `WITHOUT ROWID` for compact storage.
Key design decisions:
- **WAL mode** enables concurrent reads from workers while the main process writes.
- **`busy_timeout=5000`** plus a retry loop with `Atomics.wait`-based `sleepSync` handles `SQLITE_BUSY` errors from concurrent access.
- **Performance PRAGMAs**: `synchronous=NORMAL`, `mmap_size=512MB`, `cache_size=32MB`, `temp_store=MEMORY`, `wal_autocheckpoint=10000`.
- **Write batching**: `queueWrites()` batches pre-packed entries from tarball extraction and flushes them in a single transaction on `process.nextTick`. `setRawMany()` writes immediate batches (e.g. from `addFilesFromDir`).
- **Lifecycle**: `close()` auto-flushes pending writes, runs `PRAGMA optimize`, and closes the DB. A `process.on('exit')` handler ensures cleanup even on unexpected exits.
- **`VACUUM` after `deleteMany`** (used by `pnpm store prune`) to reclaim disk space.
### Key format
Keys are `integrity\tpkgId` (tab-separated). Git-hosted packages use `pkgId\tbuilt` or `pkgId\tnot-built`.
### Shared StoreIndex instance
A single `StoreIndex` instance is threaded through the entire install lifecycle — from `createNewStoreController` through the fetcher chain, package requester, license scanner, SBOM collector, and dependencies hierarchy. This replaces the previous pattern of each component creating its own file-based index access.
### Worker architecture
Index writes are performed in the main process, not in worker threads. Workers send pre-packed `{ key, buffer }` pairs back to the main process via `postMessage`, where they are batched and flushed to SQLite. This avoids SQLite write contention between threads.
### SQLite ExperimentalWarning suppression
`node:sqlite` emits an `ExperimentalWarning` on first load. This is suppressed via a `process.emitWarning` override injected through esbuild's `banner` option, which runs on line 1 of both `dist/pnpm.mjs` and `dist/worker.js` — before any module that loads `node:sqlite`.
### No migration from `.mpk` files
Old `.mpk` index files are not migrated. Packages missing from the new SQLite index are re-fetched on demand (the same behavior as a fresh store).
## Changed packages
121 files changed across these areas:
- **`store/index/`** — New `@pnpm/store.index` package
- **`worker/`** — Write batching moved from worker module into `StoreIndex` class; workers send pre-packed buffers to main process
- **`store/package-store/`** — StoreIndex creation and lifecycle management
- **`store/cafs/`** — Removed `getFilePathInCafs` index-file utilities (no longer needed)
- **`store/pkg-finder/`** — Reads from StoreIndex instead of `.mpk` files
- **`store/plugin-commands-store/`** — `store status` uses StoreIndex
- **`store/plugin-commands-store-inspecting/`** — `cat-index` and `find-hash` use StoreIndex
- **`fetching/tarball-fetcher/`** — Threads StoreIndex through fetchers; git-hosted fetcher flushes before reading
- **`fetching/git-fetcher/`, `binary-fetcher/`, `pick-fetcher/`** — Accept StoreIndex parameter
- **`pkg-manager/`** — `client`, `core`, `headless`, `package-requester` thread StoreIndex
- **`reviewing/`** — `license-scanner`, `sbom`, `dependencies-hierarchy` accept StoreIndex
- **`cache/api/`** — Cache view uses StoreIndex
- **`pnpm/bundle.ts`** — esbuild banner for ExperimentalWarning suppression
