Serialize tarball packaging suites in the integration test package

[StevenMcClankerton]

Linked issue

n/a — standalone packaging-test race fix; Linear link omitted as requested. Kept separate from the generic-block-value-specs feature.

Summary

Two Vitest suites — the Postgres facade tarball suite and the pgvector extension tarball suite — pnpm pack the same real @prisma/orm-postgres directory concurrently. Its prepack rewrites the skills/ tree in place, so concurrent packs corrupt each other (confirmed ENOENT race in sync-package-skills.ts). This PR fixes the race by scheduling instead of locking: both suites move into the integration test package under a dedicated Vitest project that runs its files sequentially.

The first commit on this branch implemented a cross-process lock (Lamport bakery around pnpm pack); review judged it too complex for the problem, and the second commit reverts it. The third commit is the replacement:

• test/integration/test/packaging/ now holds facade-tarball.test.ts and extension-tarball.test.ts (moved as-is; only the repoRoot depth changed).
• test/integration/vitest.config.ts splits into two projects: integration (everything else, parallelism unchanged) and packaging (test/packaging/**, fileParallelism: false). Vitest runs every fileParallelism: false project in one shared sequential execution group, so only the packing suites serialize.
• @prisma/orm-postgres and @prisma/orm-extension-pgvector lose their now-empty test rigs (test script, vitest.config.ts, test-only devDependencies) and their dead turbo.json task overrides.
• scripts/lint-single-import-root.mjs gets a narrow exemption for test/integration/test/packaging/: the moved suites' @prisma/orm-* specifiers are strings executed inside isolated scratch installs in child processes, never imports in the integration-tests module graph, so the dual-copy hazard the lint guards against cannot occur. Covered by new cases in its test.

Verification

• Both moved suites pass under the packaging project: 17/17. JSON-reporter timestamps prove sequential scheduling: facade-tarball ran 15:23:32.647–15:23:39.247, extension-tarball started 15:23:45.227 — no overlap.
• scripts/lint-single-import-root.test.mjs: 8/8, including the new exemption cases (one proves the package is still reported when the exemption list is emptied).
• pnpm lint:deps, pnpm lint:manifests, pnpm lint:vitest-timeouts, pnpm lint:legacy-name, integration-tests typecheck + lint, and both donor packages' lint all pass.

Known limitations

• The protection is scheduler-scoped: two independently launched Vitest processes could still pack concurrently. Accepted as the simpler trade-off over cross-process locking.
• orm-framework's tarball suites and orm-target-postgres's cross-shell suite stay in test:packages and pack overlapping platform-shell directories in separate Vitest projects; those directories have no in-place-rewriting prepack, and that pre-existing exposure is unchanged by this PR.
• Validation surfaced an orthogonal breakage: fresh scratch installs currently fail with ERR_PNPM_TRUST_DOWNGRADE for @vercel/detect-agent@1.2.5 (resolved via ^1.2.4 from @prisma/orm-toolchain; 1.2.5 carries no provenance where earlier versions did). This breaks the tarball suites on main in their old location too. The green runs above used a temporary local trust exclusion that is deliberately not committed — whether to pin 1.2.4 or vouch for 1.2.5 in trustPolicyExclude is a separate supply-chain decision.

Summary by CodeRabbit

• Tests

  • Separated integration and packaging tests into distinct projects.
  • Packaging tests now run sequentially with extended timeout settings.
  • Updated packaging test paths and repository layout references.
  • Updated coverage validation for the revised package structure.

• Chores

  • Removed standalone test scripts, coverage settings, and test configurations from the PostgreSQL ORM packages.
  • Updated import validation and legacy-name checks for relocated packaging tests.
  • Added tooling required by integration tests.

📝 Walkthrough

Walkthrough

The change consolidates packaging tests under the integration Vitest project. It removes package-specific Vitest configuration and Turbo test tasks, updates packaging paths and dependencies, and adds lint exemptions for the relocated tests.

Changes

Packaging test consolidation

Layer / File(s)	Summary
Integration packaging project test/integration/vitest.config.ts, test/integration/package.json, test/integration/test/packaging/*, test/integration/README.md	The integration Vitest configuration adds separate integration and serialized packaging projects. Packaging test paths, workspace dependencies, and documentation are updated.
Package test configuration removal packages/9-public/@prisma/orm-postgres/*, packages/9-public/@prisma/orm-extension-pgvector/*, turbo.json, scripts/coverage-config.test.mjs	Package-level Vitest scripts, dependencies, configurations, coverage files, coverage validation, and Turbo test tasks are removed.
Packaging lint handling scripts/lint-legacy-name.mjs, scripts/lint-single-import-root.mjs, scripts/lint-single-import-root.test.mjs	Lint checks exempt the relocated packaging subtree. Tests cover the default exemption and explicit exemption removal.

- Around line 82-90: Update packShell to acquire a cross-process lock keyed by
the package directory before invoking pnpm pack, and hold it until the complete
packing operation finishes, including cleanup and release on failure. Do not
rely on the packaging project’s fileParallelism setting, since it only
coordinates tests within one Vitest process.
