fix(reify): report added count for fresh linked installs - #9667
Merged
Conversation
Under `install-strategy=linked`, a fresh `npm install` that actually creates `.store` entries and symlinks printed `up to date, audited N packages` instead of `added N packages`, misleading users and CI into thinking nothing changed. `reify-output` counts adds with `actualTree.inventory.has(d.ideal)`. Under the linked strategy the diff's `ideal` nodes belong to the isolated store tree (locations under `node_modules/.store/<key>/node_modules/<name>`), while the `actualTree` returned after reify is the logical hoisted-layout tree. The two never share node identity, so the lookup always failed and `added` stayed `0`. The ADD branch now also counts a node when it is a real store package node (`isInStore && !isLink`), which maps 1:1 to a hoisted package add. This excludes the internal store symlinks and the top-level consumer symlink, so the count matches hoisted for registry dependencies (verified: `minimatch` 4/4, `rimraf` 12/12, `express` 69/69). Omitted/incompatible optional deps have no store entry and are still not counted, and hoisted behavior is unchanged. Known limitations (tracked separately): workspace and `file:`/`npm link` additions are represented as links rather than store nodes under linked, so they are not yet counted here — counting them is entangled with the self-link bug (#9398) and the undeclared-workspaces bug (#9618). The `--json` `add[].path` for a counted store package points to its `.store` realpath rather than a logical `node_modules/<name>` path. ## References Fixes #9623 (cherry picked from commit 0c33947)
The `ls --install-strategy=linked` tests for undeclared and declared-but-missing workspaces passed without ever entering the undeclared-workspace branch of `filterLinkedStrategyEdges` in lib/commands/ls.js, because their mock filesystems omitted the hidden `node_modules/.package-lock.json` that a real linked install writes. Without that hidden lockfile, loadActual resolves the workspace root edges via the workspace globs instead of marking them missing, so the `edge.missing` guard is never satisfied and the branch stays uncovered. This surfaced as a global coverage gate failure (ls.js branch below 100%) on the first PR after the actual-tree workspace changes in #9666, because the Test matrix only runs on PRs and not on direct pushes to release/v11. Add the hidden lockfile to both tests so they reproduce a real linked install: the undeclared workspace now resolves as a missing root edge and is correctly skipped, and the declared-but-missing workspace resolves as missing and is still reported as UNMET DEPENDENCY. This exercises both branches and restores 100% coverage. No production code changes.
