test(ci): pass bin_dest via env to survive Windows backslashes
Direct GitHub-expression interpolation of `${{ steps.pnpm.outputs.bin_dest }}` into the bash script let bash eat the backslashes in the Windows path (`C:Usersrunneradminsetup-pnpmnode_modules.binbin/pnpm`), failing with "No such file or directory". Forward the value via env so the path reaches bash unmangled.

Zoltan Kochan	01da663869	test(ci): pass bin_dest via env to survive Windows backslashes Direct GitHub-expression interpolation of `${{ steps.pnpm.outputs.bin_dest }}` into the bash script let bash eat the backslashes in the Windows path (`C:Usersrunneradminsetup-pnpmnode_modules.binbin/pnpm`), failing with "No such file or directory". Forward the value via env so the path reaches bash unmangled.	2026-05-07 08:59:18 +02:00
Zoltan Kochan	624e28f5d0	fix: bin_dest output points to self-updated pnpm, not bootstrap (#247 ) `pnpm self-update <version>` writes the target binary to `${PNPM_HOME}/bin/`, leaving the bootstrap symlink at `${PNPM_HOME}/pnpm` untouched. The `bin_dest` output was set to `${PNPM_HOME}`, so consumers invoking `${{ steps.pnpm.outputs.bin_dest }}/pnpm` got the bootstrap version (currently 11.0.4) instead of the version they requested. PATH lookup hid the bug: `${PNPM_HOME}/bin` was prepended ahead of `${PNPM_HOME}`, so `pnpm` resolved from PATH was the right one. Existing version-respect tests only checked `pnpm --version`, not `bin_dest`. Resolve `binDest` inside `runSelfInstaller` (target lives in `${PNPM_HOME}/bin` after self-update, otherwise stays at `${PNPM_HOME}`) and plumb it through to `setOutputs`. Add a regression test that invokes `${bin_dest}/pnpm --version` directly across Linux/macOS/Windows.	2026-05-07 08:55:16 +02:00

Ben Quarmby	26f6d4f2c5	fix: use npm co-located with the action node binary (#239 ) * fix: use npm co-located with the action node binary * fix: resolve npm by absolute path; guard against unset PATH Follow-up to `5a9e198`. Two refinements to the GHE self-hosted runner fix: - Spawn npm via `path.join(dirname(process.execPath), 'npm[.cmd]')` instead of relying on PATH lookup. This matches the original PR description and is robust against PATH-shadowed npm installations. - Avoid `"<dir>:undefined"` leaking into PATH when `process.env.PATH` is unset (rare, but possible in stripped environments). PATH still has the node directory prepended so npm's `#!/usr/bin/env node` shebang can resolve node on Linux/macOS. * fix: revert npm to PATH lookup; runner externals lacks npm Revert 42e75a1's switch to absolute-path npm resolution. The premise that npm is co-located with the action's node binary is false on GitHub-hosted runners: `process.execPath` points into `runner/externals/node24/bin/`, which contains node only — not npm. The absolute-path spawn produced ENOENT on Linux/macOS and "not recognized" on Windows. Go back to spawning `'npm'` and relying on PATH lookup, which works on standard runners (npm is on PATH from the runner image) and on the GHE self-hosted setup that motivated the original fix. Keep the node-directory prepend so npm's `#!/usr/bin/env node` shebang resolves, and keep the unset-PATH guard. --------- Co-authored-by: Zoltan Kochan <z@kochan.io>	2026-04-30 22:28:41 +02:00

Zoltan Kochan	bdf0af2a9d	test: add strict version-match jobs to reproduce #225 / #227 The existing version tests only check output format via regex, which is why the PATH-shadowing bug (#230) slipped through — the bootstrap pnpm's version string matched the regex just as well as the requested version. - test_version_respects_request: runs the action with `version: 9.15.5` and `version: 10.33.0` (both differ from the bootstrap) and asserts that `pnpm --version` matches exactly. Regression test for #225/#230. - test_package_manager_field: writes a `packageManager: pnpm@<v>` entry into package.json, runs the action with no `version:` input, and asserts exact match. Reproduces #227; currently expected to fail since `packageManager` extraction was intentionally not added.	2026-04-18 15:20:30 +02:00
oniani1	71c92474e7	fix: pnpm self-update binary shadowed by bootstrap on PATH (#230 ) Problem pnpm self-update installs the target version to PNPM_HOME/bin/pnpm, but the bootstrap binary at PNPM_HOME/pnpm has higher PATH precedence because addPath(pnpmHome) was called after addPath(pnpmHome/bin). @actions/core's addPath prepends, so the later call wins — the bootstrap version shadows the self-updated binary. Fix Swap the addPath call order so PNPM_HOME/bin (where self-update puts the target binary) has higher PATH precedence. The bootstrap pnpm is invoked via absolute path, so this doesn't affect the bootstrap step.	2026-04-18 15:00:23 +02:00
