Zoltan Kochan 2624472617 fix: respect peer dep range in hoistPeers when preferred versions exist (#10655)
* fix: respect peer dep range in hoistPeers when preferred versions exist

Previously, hoistPeers used semver.maxSatisfying(versions, '*') which
picked the highest preferred version from the lockfile regardless of the
peer dep range. This caused overrides that narrow a peer dep range to be
ignored when a stale version existed in the lockfile.

Now hoistPeers first tries semver.maxSatisfying(versions, range) to find
a preferred version that satisfies the actual peer dep range. If none
satisfies it and autoInstallPeers is enabled, it falls back to the range
itself so pnpm resolves a matching version from the registry.

* fix: only fall back to exact-version range for overrides, handle workspace: protocol

- When no preferred version satisfies the peer dep range, only use the
  range directly if it is an exact version (e.g. "4.3.0" from an override).
  For semver ranges (e.g. "1", "^2.0.0"), fall back to the old behavior
  of picking the highest preferred version for deduplication.
- Guard against workspace: protocol ranges that would cause
  semver.maxSatisfying to throw.
- Add unit tests for hoisting deduplication and workspace: ranges.

* fix: only apply range-constrained peer selection for exact versions

The previous approach used semver.maxSatisfying(versions, range) for all
peer dep ranges, which broke aliased-dependency deduplication — e.g. when
three aliases of @pnpm.e2e/peer-c existed at 1.0.0, 1.0.1, and 2.0.0,
range ^1.0.0 would pick 1.0.1 instead of 2.0.0.

Now the range-aware logic only activates when the range is an exact
version (semver.valid), which is the override case (e.g. "4.3.0").
Regular semver ranges fall back to picking the highest preferred version.

@pnpm/core

Fast, disk space efficient installation engine. Used by pnpm

Install

Install it via npm.

pnpm add @pnpm/core

It also depends on @pnpm/logger version 1, so install it as well via:

pnpm add @pnpm/logger@1

API

mutateModules(importers, options)

TODO

link(linkFromPkgs, linkToModules, [options])

Create symbolic links from the linked packages to the target package's node_modules (and its node_modules/.bin).

Arguments:

  • linkFromPkgs - String[] - paths to the packages that should be linked.
  • linkToModules - String - path to the dependent package's node_modules directory.
  • options.reporter - Function - A function that listens for logs.

linkToGlobal(linkFrom, options)

Create a symbolic link from the specified package to the global node_modules.

Arguments:

  • linkFrom - String - path to the package that should be linked.
  • globalDir - String - path to the global directory.
  • options.reporter - Function - A function that listens for logs.

linkFromGlobal(pkgNames, linkTo, options)

Create symbolic links from the global pkgNames to the linkTo/node_modules folder.

Arguments:

  • pkgNames - String[] - packages to link.
  • linkTo - String - package to link to.
  • globalDir - String - path to the global directory.
  • options.reporter - Function - A function that listens for logs.

storeStatus([options])

Return the list of modified dependencies.

Arguments:

  • options.reporter - Function - A function that listens for logs.

Returns: Promise<string[]> - the paths to the modified packages of the current project. The paths contain the location of packages in the store, not in the projects node_modules folder.

storePrune([options])

Remove unreferenced packages from the store.

Hooks

Hooks are functions that can step into the installation process.

readPackage(pkg: Manifest): Manifest | Promise<Manifest>

This hook is called with every dependency's manifest information. The modified manifest returned by this hook is then used by @pnpm/core during installation. An async function is supported.

Example:

const { installPkgs } = require('@pnpm/core')

installPkgs({
  hooks: {readPackage}
})

function readPackage (pkg) {
  if (pkg.name === 'foo') {
    pkg.dependencies = {
      bar: '^2.0.0',
    }
  }
  return pkg
}

afterAllResolved(lockfile: Lockfile): Lockfile | Promise<Lockfile>

This hook is called after all dependencies are resolved. It receives and returns the resolved lockfile object. An async function is supported.
