From 76a530cf441ba54bb734db97c92ce9e93df9be88 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sat, 18 Apr 2026 06:32:41 +0800 Subject: [PATCH] test(e2e): Minions v7 concurrency + OpenClaw resilience coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit minions-concurrency.test.ts spins two MinionWorker instances against the test Postgres, submits 20 jobs, and asserts zero double-claims (every job runs exactly once). This is the only test that actually proves FOR UPDATE SKIP LOCKED under real concurrency — PGLite runs on a single connection and can't exercise the race. minions-resilience.test.ts covers the six OpenClaw daily pains: 1. Spawn storm caps enforce under concurrent submit. 2. Agent stall → handleStalled() requeues; handleTimeouts() skips (lock_until guard). 3. Forgotten dispatches recoverable via child_done inbox. 4. Cascade cancel stops grandchildren mid-flight. 5. Deep tree fan-in (parent → 3 children → 2 grandchildren each) completes with the full inbox chain. 6. Parent crash/recovery resumes from persisted state. helpers.ts extends ALL_TABLES with minion_attachments, minion_inbox, and minion_jobs (FK dependents first) so E2E teardown doesn't leak rows between runs.
