* fix(lockfile): keep non-reconstructable tarball URLs when lockfileIncludeTarballUrl is false
`lockfile-include-tarball-url` defaults to `false`, so for the vast
majority of users the early return added by #10621 silently dropped
tarball URLs that cannot be reconstructed from registry+name+version —
breaking `pnpm install --frozen-lockfile` from an empty store on
GitHub Packages (`https://npm.pkg.github.com/download/<scope>/<name>/<version>/<hash>`),
JSR, and similar registries.
`false` now matches the historical (v10) heuristic: tarball URLs are
written when they are non-reconstructable, otherwise omitted.
`true` continues to force every tarball URL into the lockfile.
Refs #11276, #11407.
* chore: appease cspell
Replace "reconstructable" with "derivable" and avoid the cspell-flagged
"mypkg" placeholder in the new test fixture.
* docs(changeset): use camelCase setting name
* fix(lockfile): guard against missing tarball field in toLockfileResolution
`TarballResolution.tarball` is typed as required, but callers that
deserialize resolutions from external state can violate that. Return
early with just `integrity` if the tarball URL is missing instead of
asserting non-null at the use site (which previously paired a
`as string | undefined` cast with `tarball!.replaceAll(...)` —
contradictory signals that confused both readers and review tools).
For git-hosted tarballs (`codeload.github.com` / `gitlab.com` / `bitbucket.org`) the fetcher dropped the integrity it computed while downloading, so the lockfile only ever stored the URL. A compromised git host or man-in-the-middle could serve a substituted tarball on subsequent installs and pnpm would install it — the lockfile had no hash to compare against.
This pins the SHA-512 SRI of the raw tarball in the lockfile, in the same `sha512-<base64>` form npm-registry tarballs use. The only difference is the source: for npm we pass through `dist.integrity`, for git we compute it locally from the downloaded buffer. Subsequent installs validate the download against that integrity in the worker (`addTarballToStore` → `parseIntegrity` → hash compare), so a tampered tarball fails with `TarballIntegrityError`.
## Why git-hosted stays on `gitHostedStoreIndexKey`
The lockfile pins integrity for security, but the *store key* for git-hosted resolutions stays on `gitHostedStoreIndexKey(pkgId, { built })` rather than collapsing under the integrity-based key. Reason: git-hosted tarballs are post-processed (`preparePackage` / `packlist`), so the cached file set depends on whether build scripts ran during fetch. The integrity-only key would fold the built and not-built variants into a single slot, letting one overwrite the other and serving the wrong content if `ignoreScripts` was toggled between runs. Keeping git-hosted on the existing key shape preserves that dimension; the integrity is still validated on every fresh download.
## How the routing stays clean
The naive way to express "use gitHostedStoreIndexKey for git-hosted, integrity key for npm" is to call `isGitHostedPkgUrl(resolution.tarball)` everywhere a store key is computed — fragile, scattered, and easy to forget when adding new readers (Copilot caught two of those during review). Instead, a typed annotation: `TarballResolution` gets an optional `gitHosted: boolean` field. The git resolver sets it; the lockfile loader (`convertToLockfileObject`) backfills it for entries written by older pnpm versions; `toLockfileResolution` carries it through on serialize. Every consumer reads `resolution.gitHosted` directly. URL detection lives in exactly two places — the resolver and the loader — instead of seven.
## Changes
### Security fix
- `fetching/tarball-fetcher/src/gitHostedTarballFetcher.ts` — return the `integrity` that the inner remote-tarball fetch already computed (was being silently dropped by the destructure).
### Lockfile schema (additive)
- `@pnpm/lockfile.types` and `@pnpm/resolving.resolver-base` — `TarballResolution` gains optional `gitHosted: boolean`.
- `@pnpm/resolving.git-resolver` — sets `gitHosted: true` on every git-hosted tarball it produces.
- `@pnpm/lockfile.fs` (`convertToLockfileObject`) — backfills the field on load for older lockfiles via inlined URL detection.
- `@pnpm/lockfile.utils` (`toLockfileResolution`, `pkgSnapshotToResolution`) — preserve / read the field.
### Store-key consumers (now one-line typed reads, dropped the URL-sniffing dep)
- `installing/package-requester` (`getFilesIndexFilePath`)
- `store/pkg-finder` (`readPackageFileMap`)
- `modules-mounter/daemon` (`createFuseHandlers`)
- `building/after-install` (side-effects-cache lookup + write)
- `store/commands/storeStatus`
- `installing/deps-installer` (agent-mode store-controller wrapper)
### Fetcher routing
- `fetching/pick-fetcher` — `pickFetcher` prefers `resolution.gitHosted`; URL fallback retained for ad-hoc resolutions.
### Tests
- New integrity-validation test in `tarball-fetcher` (mismatched `integrity` on the resolution must throw `TarballIntegrityError`).
- New git-hosted lookup test in `pkg-finder` asserting routing through `gitHostedStoreIndexKey` even when integrity is present.
- New `toLockfileResolution` test asserting `gitHosted: true` flows through serialization.
- `fromRepo.ts` lockfile snapshot updated for the now-pinned integrity + `gitHosted: true`.
- `git-resolver` tests updated to assert `gitHosted: true` in produced resolutions.
* chore: upgrade @typescript/native-preview to 7.0.0-dev.20260421.2
- Add explicit `types: ["node"]` to the shared tsconfig because tsgo
20260421 no longer auto-acquires `@types/*` from `node_modules`.
- Refactor test files to explicitly import jest globals (`describe`,
`it`, `test`, `expect`, `beforeEach`, etc.) from `@jest/globals`
instead of relying on `@types/jest` ambient declarations. Under the
new tsgo build, `import { jest } from '@jest/globals'` shadows the
ambient `jest` namespace, breaking `@types/jest`'s `declare var
describe: jest.Describe;` globals.
- Add `@jest/globals` to each package's devDependencies where tests
now import from it, and add `@types/node` to packages that need it
but were relying on hoisted resolution.
- Replace `fail()` calls with `throw new Error(...)` since `fail` is
no longer globally available.
* chore: fix remaining tsgo type-strictness errors
- Strip `as <PnpmType>` casts on objects passed to toMatchObject /
toStrictEqual / toEqual; @jest/globals rejects the typed objects
(which include AsymmetricMatchers) vs. the repo-specific type.
- Type `jest.fn<...>()` explicitly where the mock's signature matters
for toHaveBeenCalledWith.
- Replace `beforeEach(() => X)` with `beforeEach(() => { X })` so the
return value is void, as the stricter jest typing requires.
- Use `expect.objectContaining({...})` in one place where the full
expected object triggered stricter type resolution.
- Cast `prompt.mock.calls` arg through `as unknown as Record<...>[]`
for patch.test.ts's nested-array matchers.
- Fix off-by-one `<reference path>` in pnpm/test/getConfig.test.ts
that only surfaced now.
- Move `@jest/globals` from devDependencies to dependencies in the
two `__utils__` packages that import it from `src/`.
- Clean up unused imports from the @jest/globals migration.
* chore: address Copilot review on #11332
- Move misplaced `@jest/globals` imports to the top import block in
checkEngine, run.ts, and workspace/root-finder tests where the
script dropped them below executable code.
- Replace `try { await x(); throw new Error('should have thrown') } catch`
in bins/linker, lockfile/fs, and resolving/local-resolver tests with
`await expect(x()).rejects.toMatchObject({...})`. The old pattern
swallowed an unrelated `throw` if the under-test call silently
succeeded, which would fail on the catch-block assertion with a
misleading message.
