test(taskmill): add integration tests and criterion benchmarks#21
Merged
Conversation
Add 15 integration tests covering priority ordering, retry lifecycle, preemption+resume, backpressure gating, group concurrency, run loop, max concurrency enforcement, fail-fast children, crash recovery, batch submit, IO metrics tracking, and snapshot diagnostics. Add 7 criterion benchmark groups (12 individual benchmarks) measuring submit throughput, dedup performance, dispatch+complete throughput, peek_next scaling, concurrency scaling, batch submit, and mixed priority dispatch. Fix two bugs discovered during testing: - GroupLimits used tokio::sync::RwLock with blocking_read/write which panics in async contexts; switched to std::sync::RwLock - Store migrations were not idempotent (ALTER TABLE ADD COLUMN fails on re-open); now ignores "duplicate column name" errors
