fix(test): stop the sideband ceiling proxy before afterEach removes its home (Windows EBUSY) - #5747
Conversation
…s its home #5740 moved the sideband ceiling case's teardown to onTestFinished. Bun runs the file's afterEach first, so afterEach removed .tmp-server-live-test while the case's proxy still held files open inside it. POSIX allows that; Windows answers EBUSY after the removal retries, the proxy is never stopped, and every later case's beforeEach/afterEach fails on the same locked directory (windows 8/9 on dev 6c171aa, run 35992525426). The case now hands its teardown to a slot the file's afterEach awaits before anything else, which also runs when the harness budget ends the case. The event-driven wait, every assertion, and the 20s budget are unchanged. Refs #4997

#5740이 그 케이스의 서버 끄기를 고친 테스트는 끄기 함수를 모듈 칸 라인 - 라인 - 65–69행과 647–661행 — 칸은 끄기를 기다리기 전에 비워요. 50MB를 보내는 도중에 메인테이너의 판단이 필요한 지점 풀리퀘스트에 붙은 CI(run 35995465444)는 윈도우 샤드를 건너뛰어요. 전체 레인으로 돌린 run 35995464326의 윈도우 8/9는 이 글을 쓸 때 아직 돌아가는 중이었어요. 맥에서 본 순서만으로 합칠지, 8/9가 초록이 된 뒤에 합칠지 정해 주세요. 너의 추천

Report teardown and TEST_DIR cleanup failures separately.
If caseTeardown rejects and removeTreeWithRetry(TEST_DIR) also throws, the finally block throws teardownFailure and masks the removal error. Capture the cleanup error and report both errors after the cleanup block. The inspected repository does not configure or enforce Biome's noUnsafeFinally rule, so remove that unsupported claim.

Summary
Full Cross-platform CI on
dev6c171aa5a6(run 35992525426) failed windows 8/9 intests/server/server-live.test.ts. The first failure was the sideband ceiling case, and every later case then hitEBUSY: resource busy or locked, rm '…\tests\server\.tmp-server-live-test'inbeforeEach/afterEachand ran out its ~30 s budget. The shard was green on359616ef20(run 35958742680).Root cause: #5740 moved that case's teardown (stopping the proxy and the mock upstream) to
onTestFinished. Bun runs the file'safterEachbeforeonTestFinished(checked on Bun 1.4.0), soafterEachremovedTEST_DIRwhile the case's proxy still held files open inside it. POSIX allows that removal. Windows answersEBUSYonce the retries run out, the proxy is never stopped, and the directory stays locked for every later case.Fix: the case hands its teardown to a module-level
caseTeardownslot, and the file'safterEachnow awaits that slot first, before restoring the environment and removingTEST_DIR.afterEachalso runs when the 20 s budget ends a case, so the timeout path is still covered. A teardown failure is rethrown only after the rest ofafterEachhas run. The event-driven wait, every assertion, the stall diagnostic, and the budget are unchanged.onTestFinishedis no longer used in this file.Refs #4997
