From bf68ad4d934f8efc787d55ca355b946b94c015ed Mon Sep 17 00:00:00 2001 From: Tom Boucher Date: Fri, 29 May 2026 11:18:10 -0400 Subject: [PATCH] fix(tests): deterministic concurrency via injectable clock seam; delete flaky racing tests (#459) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(#453): add deterministic clock seam to lock modules Introduces get-shit-done/bin/lib/clock.cjs exporting realClock with now() (Date.now) and sleep() (Atomics.wait). acquireStateLock, writeStateMd, and readModifyWriteStateMd in state.cjs each accept an optional trailing clock param (default: realClock). withPlanningLock in planning-workspace.cjs gains the same seam. No production behavior change — all callers that omit the param continue to use realClock. Adds tests/helpers/clock.cjs (makeFakeClock) and tests/clock-seam.test.cjs with 20 deterministic in-process tests covering: lock serialization, timeout throw at maxWaitMs boundary, stale-lock takeover, lock released on error path, withPlanningLock timeout recovery, exit-cleanup integration, readModifyWriteStateMd call-site coverage (7 cmd*), and roadmap analyze behavioral assertion (50 phases, no elapsed-time gate). Deletes/converts per research verdicts: removes 11 source-grep/elapsed-time/ non-deterministic-concurrent tests across concurrency-safety.test.cjs, locking-bugs-1909-1916-1925-1927.test.cjs, and bug-1974-context-exhaustion- record.test.cjs. All deleted tests have deterministic replacements in clock-seam.test.cjs or surviving barrier-based tests.
