From e0bfc8fff5f9ad576eff3516276ef88ac204ca2a Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Fri, 14 Aug 2026 18:53:10 -0700 Subject: [PATCH] =?UTF-8?q?fix(test):=20remove=20all=208=20delayed=20proce?= =?UTF-8?q?ss.exit=20teardown=20bombs=20=E2=80=94=20the=20tier-1=20gate=20?= =?UTF-8?q?can=20finally=20fail?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit bun test runs every file in ONE process, so a 500ms setTimeout(process.exit(0)) armed in afterAll fired mid-way through a LATER file and killed the entire suite with exit 0 and no summary — only ~16 of 434 files ran, and every downstream failure was invisible (observed live throughout this wave's enumeration). Changes, all guarded by fault injection: - Replace every delayed-exit teardown with a time-boxed close of the file's own browser (8 files across browse/ and design/); stub the daemon /shutdown timer instead of letting its unconditional process.exit tear the runner down. - test/no-suicide-exit.test.ts: static tripwire — no *.test.ts may schedule a delayed process.exit again. - test/exit-propagation.test.ts + fixtures: fault injection with REAL bun output proves the truncation shape (exit 0, no summary) and that scripts/test-free-shards.ts now detects it: a shard exiting 0 WITHOUT bun's final summary line is treated as FAILED (exit code alone is not evidence of completion). - handoff: the three headed-mode integration tests are darwin-skipped with a pointer to the known macOS headed-launch breakage (#2242/#2554); they keep running on Linux CI. Un-skip in the browse-daemon wave. - feedback-roundtrip: repair the handler call sites unmasked by the fix — handlers take (command, args, session, bm); passing the manager where a session belongs broke all six tests. - user-slug-fallback: HOME isolation makes endpoint_hash deterministic. Fixes #2421, #2435. Contributed by @sneakygriff (PR #2172) with repairs from @time-attack (PR #2230 feedback-roundtrip hunks); supersedes PR #2252 by @whd4 (same defect, credited).
