## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Database, server, and CLI tests use real PostgreSQL fixtures. > - Each fixture must own its server until PostgreSQL has stopped. > - The old teardown returned after five seconds even when its server remained alive. > - A startup failure could then mark the host unsupported and skip database coverage. > - This pull request waits for owned shutdown and makes supported-host startup failures fail collection. > - A shared-server command reduces process creation while keeping each fixture's database isolated. ## Linked Issues or Issue Description Refs: #7756 for related development-process ownership. That development-server issue remains outside this test-fixture fix. Related PR: #16799 collects macOS startup diagnostics. This PR changes test shutdown and failure behavior. **What happened?** Repeated test runs can exhaust macOS PostgreSQL semaphore resources. The fixture abandoned slow shutdown and swallowed stop errors. The support probe converted ordinary startup failures into skipped integration coverage. **Expected behavior** Tests must stop their PostgreSQL servers, retain files if stop fails, and report resource exhaustion as a failure. Fixtures on a shared server must not close another database's clients. **Steps to reproduce** Start a fixture whose PostgreSQL stop exceeds five seconds, or make a supported-host startup fail with semaphore exhaustion. The former helper returned from teardown or reported unsupported coverage. The new regression tests exercise both paths without exhausting host resources. **Paperclip version or commit** Source checkout based on current master. **Deployment mode** Local source development and CI tests. ## What Changed - Add explicit ownership for test PostgreSQL children. Wait for fast shutdown, then request immediate PostgreSQL shutdown if needed. Keep cleanup idempotent and fail when exit cannot be confirmed. - Publish reusable templates only after clean shutdown. Do not publish a crashed or immediately stopped cluster. - Stop owned children on POSIX worker signals and process exit. Preserve test directories when shutdown fails. Remove conflicting dependency exit hooks. - Retry port collisions only. Fail collection for resource exhaustion, unavailable configured servers, and other startup failures on supported platforms. Preserve skips for explicitly unsupported platforms. - Move administrative-server support into the common fixture used by database, server, and CLI tests. Close clients at database scope and migrate cloned templates before use. - Add a directly invoked shared-server runner to own one test server and run suites against separate disposable databases. Preserve child exit status and support an existing disposable server. - Unify cancellation: stop and wait for the test process group before PostgreSQL teardown. Add nested-process coverage, real worker-exit coverage, shutdown regressions, shared-database isolation checks, and setup documentation. Replace ignored heartbeat completion polls with the existing execution drain before asserting persisted outcomes. - Finish owned cluster-directory cleanup after signal-driven cancellation. Preserve prepared templates across shared-fixture tests. Remove stopped directories asynchronously, using native removal on POSIX with a Node fallback. - Align database and CLI fixture hook budgets with the existing 30-second server budget. This lets the ten-second shutdown protocol finish and report errors. The idle-sleep suite uses the existing 90-second fixture budget for its unusually large final directory cleanup. ## Verification - The semaphore-exhaustion regression failed against the old helper because it resolved to `supported: false` instead of rejecting. - All 37 focused tests pass on the final runtime code (`e4de00ab40`). They include real worker exit, SIGTERM, nested-process SIGINT/SIGTERM cancellation with PostgreSQL available during child cleanup, failed template shutdown, unsupported platforms, stale SQL templates, and directory removal. A child exiting with status 7 makes the shared-server runner return status 7 after cleanup. - Full local `pnpm -r typecheck` and `pnpm build` pass on the final runtime code (`e4de00ab40`). Subsequent changes only adjust server-test lifecycle waits, the idle-sleep cleanup budget, and documentation; the server typecheck also passes with those final tests. - A fresh shared-server run on `90b65fd8ad` passed all 68 database files and 297 tests. Earlier preparation runs had two ten-second teardown timeouts and a stale-template failure; the final helper migrates cloned templates and permits the full shutdown budget. These earlier failures remain accounted for here. - The local full repository attempt stopped on a Discord receiver-lease test after 338 passing chat tests. That exact case passed in isolation. This full-suite attempt is not a pass. - On `90b65fd8ad`, [server shard 6](https://github.com/paperclipai/paperclip/actions/runs/41496495253/job/125452949369) and its one unchanged retry reported two 15-second cached-input heartbeat timeouts and a 30-second idle-sleep teardown timeout. All ten cached-input cases then passed locally with their original deadlines. A local parallel run of the full files reported eight behavioral/hook failures and two suite teardown timeouts (281 tests passed). - Serial idle-sleep runs passed all 225 test assertions but overran the 30-second final hook. Tracing measured client closure in 4 ms, PostgreSQL exit after 5 seconds, and synchronous directory removal taking another 35 seconds. Asynchronous Node removal and native removal also exceeded that hook under the full workload. Cleanup now remains asynchronous and awaited, and only this heavy suite's final hook uses the existing 90-second fixture budget. No PostgreSQL shutdown deadline or test assertion was weakened. The serial run then passed the complete idle-sleep file, including all 225 tests and teardown. Its heartbeat file passed 63/64 cases, exposing an ignored three-second completion poll. After replacing that poll with an execution drain, another timer case exposed the same pattern (63/64 passed). All remaining ignored completion polls now await execution drain without changing test deadlines. The complete heartbeat file then passed all 64 tests. The intentional asserted lock-contention poll is unchanged. The final server typecheck passes, and a process audit found no PostgreSQL server left by the completed local runs. - On final head `2cf316d3f571e4516890cba743ecffeb9703cce3`, the previously failing server shard 6, database lane, full typecheck, and build passed. The [first CI attempt](https://github.com/paperclipai/paperclip/actions/runs/41506358136) then lost self-hosted runners in the canary and serialized-server lanes, with additional jobs cancelled. The server-2 lane had one 30-second timeout in the unchanged workspace-recovery HTTP Retry test (2,282 other tests passed). That exact test passed locally with its original deadline (28.78 seconds including imports). One unchanged retry of only failed and cancelled jobs completed successfully on the exact final commit (workflow attempt 2). The workspace-recovery timeout case and every interrupted lane passed; successful first-attempt jobs were retained. The additional Paperclip Review check remains queued, waiting for its assigned agent; it has no unresolved GitHub review threads. Greptile completed review on this exact final head at 5/5, with zero unresolved review threads. All four original review findings and their threads are resolved; additional Windows shutdown, cancellation-directory, and template-reuse findings are fixed. - `pnpm check:module-boundaries` and `git diff --check` passed. Post-run process checks found no PostgreSQL servers left by the completed verification runs. ## Risks - Immediate PostgreSQL shutdown can require crash recovery. This fallback applies to disposable test clusters and runs only after fast shutdown times out. - No process can handle `SIGKILL` or machine power loss. Host resource cleanup remains a separate backstop. - Directory cleanup on cancellation applies to the shared-server runner's own cluster. Directly terminated test workers stop their PostgreSQL process but retain disposable files for inspection. The process-exit guard cannot await file removal. - The two-second `pg_ctl -W` deadline bounds signal dispatch. It is separate from the five-second and thirty-second server-exit waits. A control-command failure fails cleanup and retains its directory; it does not report successful cleanup or force-delete live files. - Shared fixtures require a disposable PostgreSQL server and a role that can create databases. The directly invoked shared command is opt-in; the existing `pnpm test` command remains available. - These changes do not stop unrelated development servers or delete host-wide IPC resources. Clean shutdown uses the owned `pg_ctl` binary on every supported platform. Its real control path was tested on macOS. A Windows host was not available for live verification; POSIX signal tests skip on Windows. ## Model Used - OpenAI Codex, based on GPT-6. The runtime does not expose the exact serving variant or context-window size.
