📝 WalkthroughWalkthroughThe ingest-type lint test now creates UUID-scoped probe directories, removes stale runs, registers process cleanup handlers, lints only current probes, and validates cleanup and concurrent-run behavior. ChangesIngest probe isolation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This test-only change can delete an active concurrent probe directory after five minutes, causing lint targets to disappear and producing nondeterministic CI failures; merge should wait for an ownership or liveness safeguard. Suggested reviewers: Important Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional. ❌ Failed checks (1 inconclusive)
✅ Passed checks (6 passed)
✨ Finishing Touches🧪 Generate unit tests (beta)

- Around line 45-69: Update sweepStaleProbeRuns so directory mtime alone cannot
remove an active probe run: track and validate ownership for the full run
lifetime, such as by checking the owner process is still alive before deletion.
Extend the concurrent-run test to age an active run beyond STALE_PROBE_MS and
assert its directory remains until the run completes.
- Around line 83-90: Add focused tests in the existing cleanup test suite for
the process exit handler and both SIGINT and SIGTERM handlers registered by the
probe-run setup. For each case, create a run directory, invoke the captured
handler, and assert the directory is removed; stub process.exit only for signal
tests and verify exit codes 130 for SIGINT and 143 for SIGTERM.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Do not use directory mtime as the only liveness check.
Line 61 deletes a run after five minutes without filesystem changes. A live worker can remain in linting or be paused longer than that period. Its probe directory then becomes stale by this check.
A concurrent worker can delete the active worker’s lint targets before lint(runDirs) completes. This violates probe isolation and makes the test nondeterministic.
Track active ownership for the full run lifetime, such as with validated owner-process liveness. Extend the concurrent-run test to age a still-active run past the cutoff and assert that it remains.
As per path instructions, tests must cover concurrent-run behavior.

📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win
Add observable tests for termination cleanup.
The new tests exercise stale sweeping only. They do not invoke the exit, SIGINT, or SIGTERM cleanup paths.
Add focused tests that create a run directory, invoke each cleanup handler, and assert that the directory is removed. Stub process.exit only within the relevant signal test and verify its expected exit code.
As per path instructions, “For process and signal listener behavior, invoke handlers and assert resulting filesystem state rather than merely asserting listener registration.”

Fixes #15523
What changed
tools/oxlint-plugins/comfyIngestTypes.test.tsnow gives every test process its own probe run instead of writing to fixed paths undersrc/,src/platform/, andbrowser_tests/fixtures/:__ingest_type_probes__/<run-pid-uuid>/, so two vitest processes (or a vitest run overlappingpnpm lint) never share probe paths.src+browser_teststrees (~3,000 files). The repo's own.oxlintrc.jsonis still the config under test, so the scoping/severity property is unchanged.afterAll, on processexit, and onSIGINT/SIGTERM(registered before any probe is written, so the whole write window is covered).beforeAllremoves probe directories older than five minutes, so leftovers from a hard-killed run (where no signal handler can run) are cleaned by the next run; fresh siblings are preserved so a concurrently starting run is never reaped. Covered by three new unit tests (stale removed, fresh kept, missing root tolerated).browser_testsfixture assertion compared oxlint's POSIX-stylefilenameagainstpath.join(...), which emits\on Windows and never matches — the test was failing on Windows onmain(1 failed | 16 passed). It now matches the run-relative POSIX suffix.Why the
.gitignoreline from the issue is intentionally not addedI verified with oxlint 1.77 that a
.gitignoreentry hides the probe directories from oxlint even when they are passed as explicit targets and with--no-ignore—oxlint src/__ingest_type_probes__then reportsNo files found to lint. Gitignoring the roots would therefore make every probe invisible to the exact lint call under test and turn the suite red on every run. Signal/exit cleanup plus the stale sweep bound the exposure instead: the only remaining window is aSIGKILLed run between the kill and the next unit-test run, and the leftovers are still plainly visible ingit statusrather than silently ignored.Verification
