The root contains functional directories organized by domain:\n\n### Core Directories\n\n- `pnpm/`: The CLI entry point and main package.\n- `pkg-manager/`: Core package management logic (installation, linking, etc.).\n- `resolving/`: Dependency resolution logic (resolvers for npm, tarballs, git, etc.).\n- `fetching/`: Package fetching logic.\n- `store/`: Store management logic (content-addressable storage).\n- `lockfile/`: Lockfile handling, parsing, and utilities.\n\n### CLI & Configuration\n\n- `cli/`: CLI command implementations and infrastructure.\n- `config/`: Configuration management and parsing.\n- `hooks/`: pnpm hooks (readPackage, etc.).\n- `completion/`: Shell completion support.\n\n### Other Functional Directories\n\n- `network/`: Network-related utilities (proxy, fetch, auth).\n- `workspace/`: Workspace-related utilities.\n- `exec/`: Execution-related commands (run, exec, dlx).\n- `env/`: Node.js environment management.\n- `cache/`: Cache-related commands and utilities.\n- `patching/`: Package patching functionality.\n- `reviewing/`: License and dependency review tools.\n- `releasing/`: Release and publishing utilities.\n\n### Shared Utilities\n\n- `packages/`: Shared utility packages (constants, error handling, logger, types, etc.).\n- `fs/`: Filesystem utilities.\n- `crypto/`: Cryptographic utilities.\n- `text/`: Text processing utilities.\n\n## Setup & Build\n\nTo set up the environment and build the project:\n\n```bash\npnpm install\npnpm run compile\n```\n\n## Testing\n\nNever run all tests in the repository as it takes a lot of time.\n\nRun tests for a specific project instead:\n\n```bash\n# From the project directory\npnpm test\n\n# From the root, filtering by package name\npnpm --filter test\n```\n\nOr better yet, run tests for a specific file:\n\n```bash\npnpm --filter test \n```\n\nOr a specific test case in a specific file:\n\n```bash\npnpm --filter test -t \n```\n\n## Linting\n\nTo run all linting checks:\n\n```bash\npnpm run lint\n```\n\n## Contribution Workflow\n\n### Changesets\n\nIf your changes affect published packages, you MUST create a changeset file in the `.changeset` directory. The changeset file should describe the change and specify the packages that are affected with the pending version bump types: patch, minor, or major.\n\n**IMPORTANT: Always explicitly include `\"pnpm\"` in the changeset** with the appropriate version bump (patch, minor, or major). The pnpm CLI will only receive automatic patch bumps from its dependencies, so if your change warrants a minor or major version bump for the CLI, you must specify it explicitly. The changeset description will appear on the release notes page.\n\nExample:\n\n```\n---\n\"@pnpm/core\": minor\n\"pnpm\": minor\n---\n\nAdded a new setting `blockExoticSubdeps` that prevents the resolution of exotic protocols in transitive dependencies [#10352](https://github.com/pnpm/pnpm/issues/10352).\n```\n\n**Versioning Guidelines for pnpm CLI:**\n- **patch**: Bug fixes, internal refactors, and changes that don't require documentation updates\n- **minor**: New features, settings, or commands that should be documented (anything users should know about)\n- **major**: Breaking changes\n\n### Commit Messages\n\nFollow the [Conventional Commits](https://www.conventionalcommits.org/) specification.\n - `feat`: a new feature\n - `fix`: a bug fix\n - `docs`: documentation only changes\n - `style`: formatting, missing semi-colons, etc.\n - `refactor`: code change that neither fixes a bug nor adds a feature\n - `perf`: a code change that improves performance\n - `test`: adding missing tests\n - `chore`: changes to build process or auxiliary tools\n\n## Code Style\n\nThis repository uses [Standard Style](https://github.com/standard/standard) with a few modifications:\n- **Trailing commas** are used.\n- **Functions are preferred** over classes.\n- **Functions are declared after they are used** (hoisting is relied upon).\n- **Import Order**:\n 1. Standard libraries (e.g., `fs`, `path`).\n 2. External dependencies (sorted alphabetically).\n 3. Relative imports.\n\nTo ensure your code adheres to the style guide, run:\n\n```bash\npnpm run lint\n```\n\n## Common Gotchas\n\n### Error Type Checking in Jest\n\nWhen checking if a caught error is an `Error` object, **do not use `instanceof Error`**. Jest runs tests in a VM context where `instanceof` checks can fail across realms.\n\nInstead, use `util.types.isNativeError()`:\n\n```typescript\nimport util from 'util'\n\ntry {\n // ... some operation\n} catch (err: unknown) {\n // ❌ Wrong - may fail in Jest\n if (err instanceof Error && 'code' in err && err.code === 'ENOENT') {\n return null\n }\n \n // ✅ Correct - works across realms\n if (util.types.isNativeError(err) && 'code' in err && err.code === 'ENOENT') {\n return null\n }\n throw err\n}\n```\n\n## Key Configuration Files\n\n- `pnpm-workspace.yaml`: Defines the workspace structure.\n- `package.json` (root): Root scripts and devDependencies.\n- `CONTRIBUTING.md`: Detailed contribution guidelines.\n" }, { "idSha256": "3f21b4ea2fbe67cd553dbcfae108e6632bdb6c655218a1e4ad5a543cc24800f4", "type": "command_execution", "status": "completed", "originalLine": 16, "outputSha256": "e7f36094c5dee63926e357a9c1a3c8e19e8bfe56e7dd429dc8291467ccd5076a", "outputBytes": 1468, "exitCode": 0, "stdout": "}\n\nasync function getChangedDirsSinceCommit (commit: string, workingDir: string, testPattern: string[], changedFilesIgnorePattern: string[]): Promise {\n let diff!: string\n try {\n diff = (\n await execa('git', [\n 'diff',\n '--name-only',\n commit,\n '--',\n workingDir,\n ], { cwd: workingDir })\n ).stdout\n } catch (err: unknown) {\n assert(util.types.isNativeError(err))\n throw new PnpmError('FILTER_CHANGED', `Filtering by changed packages failed. ${'stderr' in err ? err.stderr as string : ''}`)\n }\n const changedDirs = new Map()\n\n if (!diff) {\n return []\n }\n\n const allChangedFiles = diff.split('\\n')\n // The prefix and suffix '\"' are appended to the Korean path\n .map(line => line.replace(/^\"/, '').replace(/\"$/, ''))\n const patterns = changedFilesIgnorePattern.filter(\n (pattern) => pattern.length\n )\n const changedFiles = (patterns.length > 0)\n ? micromatch.not(allChangedFiles, patterns, {\n dot: true,\n })\n : allChangedFiles\n\n for (const changedFile of changedFiles) {\n const dir = path.dirname(changedFile)\n\n if (changedDirs.get(dir) === 'source') continue\n\n const changeType: ChangeType = testPattern.some(pattern => micromatch.isMatch(changedFile, pattern))\n ?
