test(shutdown): give the launcher startup wait room on a loaded runner#3061lidge-jun wants to merge 3 commits into
Conversation
The three signal cases in tests/shutdown-launcher.test.ts each cold-spawn `node bin/ocx.mjs start` and wait for /healthz, and they run back to back. The wait was capped at 20s, which on a loaded runner is the failure rather than a bound on one: observed failures land at 20061ms and 20168ms, exactly the budget. Reproduced on a Linux host at origin/dev (0844dc9) 1-in-3 in isolation, and it failed CI test 2/4 on PR #3057, a branch that does not touch this file. Startup latency is not what any assertion here is about. The test exists to prove that signalling only the launcher PID tears down the Bun proxy, frees the port, and restores the Codex config. Raise the startup wait to 90s and the per-test ceiling from 45s to 130s so the wait can actually elapse; every assertion is unchanged.

리뷰 · 우선순위 72 / 80이 PR은 제품 코드가 아니라 테스트 한 파일만 고칩니다. 대상은 왜 지금 숫자는 이미 저장소 안에 같은 값이 있습니다. 다만 90초/130초는 CI 하네스와 충돌합니다. 리눅스 샤드는 저자가 이미 적은 두 번째 원인도 남아 있습니다. 90초를 다 쓴 실패가 한 번 있었고, 바로 다음 케이스는 820ms에 떴습니다. 느린 시작으로는 설명이 안 되고, 라인 110 - 시작 대기를 20_000에서 90_000으로 올린다. 측정된 실패(20061/20168ms)는 이걸로 커버되지만, 한 테스트의 대기만 115초에 가깝다 메인테이너의 판단이 필요한 지점

…lthy The test spawned the launcher with stdio ignored, so a startup failure surfaced only as expect(up).toBe(true) with Received: false and no evidence whatsoever. A CI failure that consumed the full 90s wait could not be distinguished from a slow start, which is exactly the ambiguity that made this flake expensive to chase. Pipe stdout/stderr and print them when the health wait expires.

Bun test explicit test timeout third argument overrides --timeout CLI default timeout
💡 Result:
Yes, an explicit per-test timeout provided as the third argument to the test function overrides the --timeout CLI flag [1][2][3]. In Bun, while the --timeout CLI option (or the test configuration in bunfig.toml) sets a global default timeout for all tests [1][4][5], you can specify a unique timeout for an individual test by passing a number (in milliseconds) as the third argument to the test function [1][3]. This per-test setting takes precedence over the global default [3]. Example: test("custom timeout test", async => { // This test will have a 10-second timeout, // even if --timeout was set to a different value via CLI await doSomethingSlow; }, 10000);

Raise the Linux batch timeout for tests/shutdown-launcher.test.ts.
The test at lines 121–150 allows 90 seconds for startup, 15 seconds for launcher exit, and 10 seconds for port cleanup. Its explicit 130-second timeout overrides Bun’s 60-second default. However, scripts/ci/run-bun-test-batches.sh:6,112-114 terminates each Linux batch after 120 seconds, so a slow run can be killed before completion and cleanup.
Set BUN_TEST_BATCH_TIMEOUT_SECONDS above 130 seconds, or run this test in a dedicated batch.

…arrives The macOS CI failure printed "(nothing)" for the launcher output across the full 90s wait, and the next case in the same file came up in 820ms. That rules out a slow or loaded machine: the process never reached its startup banner. Also report whether the child had exited, which separates a crashed launcher from one still running but never binding. The likeliest remaining cause is the freePort() gap — it binds :0, reads the port, then closes, so another process on the runner can claim it before the proxy does.

Requesting changes on exact head 872bf64e4f674cc7fb9a3413620031856072464c. The new exact-head macOS job still fails at tests/shutdown-launcher.test.ts:135 after waitUntil(..., 90_000) returns false. That is direct evidence that the 20-second ceiling was not the only failure mode: this patch turns the same startup failure into a 90-second stall without making the test reliable.
The new budgets also exceed the surrounding CI envelope. Each test permits 130 seconds, while scripts/ci/run-bun-test-batches.sh wraps the entire multi-file batch in GNU timeout with a 120-second default and invokes Bun with --timeout 60000. This file runs three launcher cases. On the loaded-runner path this change is meant to tolerate, the outer batch can terminate before the per-test diagnostic or assertion does.
Please use the captured launcher output from the failed macOS run to identify the non-start cause first, including the free-port close/rebind race and owned-service-home setup noted in the patch. Then choose a bounded startup budget that fits both the per-test and whole-batch contracts, or move this process-heavy file into an explicitly isolated CI lane with its own documented outer budget. Keep the shutdown, port-release, config-restore, and state-file assertions unchanged. The current red macOS exact-head result must be green before approval.

What this PR now is
Two things, and I want to be precise about which one is a fix and which one is evidence.
1. The 20s startup budget was itself the failure — fixed. The three signal cases each cold-spawn
node bin/ocx.mjs startand wait on/healthz, back to back in one file. The wait was capped at 20s and the per-test ceiling at 45s. Observed failures landed at 20061ms and 20168ms: the budget, not a hang. Raised to 90s and 130s; they must move together or the longer wait is decorative. Reproduced 1-in-3 on Linux atorigin/dev; after the change, 12 sequential and 6 parallel runs all green.2. A second, distinct cause exists on macOS — instrumented, not fixed. This is the honest part.
The test discarded the launcher's output (
stdio: "ignore"), so a startup failure surfaced asexpect(up).toBe(true)/Received: falseand nothing else. That is what made this expensive to chase. Now stdout, stderr and the child's exit state are captured and printed when the health wait expires.It paid off immediately. Two macOS CI failures on this branch report:
That narrows it considerably:
exited=false, the process is alive the whole time.An alive, silent launcher is blocked before it reaches its first write. I did not find which call, and I am not going to guess and label a guess a fix. It did not reproduce on Linux across 12 sequential runs, 6 parallel runs, and 8 direct launcher spawns (all healthy in 589-796ms), which fits a macOS-specific path — the
claimOwnedServiceHomefixture writes aLaunchAgentsplist on darwin and aservice-state.jsonownership claim, so a service-manager probe is the first place I would look next.Why land this anyway
It strictly improves the situation. One real cause is removed and proven. The remaining one now produces a diagnosable failure instead of a bare
