When MemoryStreamBridge queue reaches capacity, publish_end() previously used the same 30s timeout + drop strategy as regular events. If the END sentinel was dropped, subscribe() would loop forever waiting for it, causing the SSE connection to hang indefinitely and leaking _queues and _counters resources for that run_id. Changes: - publish_end() now evicts oldest regular events when queue is full to guarantee END sentinel delivery — the sentinel is the only signal that allows subscribers to terminate - Added per-run drop counters (_dropped_counts) with dropped_count() and dropped_total properties for observability - cleanup() and close() now clear drop counters - publish() logs total dropped count per run for easier debugging Tests: - test_end_sentinel_delivered_when_queue_full: verifies END arrives even with a completely full queue - test_end_sentinel_evicts_oldest_events: verifies eviction behavior - test_end_sentinel_no_eviction_when_space_available: no side effects when queue has room - test_concurrent_tasks_end_sentinel: 4 concurrent producer/consumer pairs all terminate properly - test_dropped_count_tracking, test_dropped_total, test_cleanup_clears_dropped_counts, test_close_clears_dropped_counts: drop counter coverage Closes #1689 Co-authored-by: voidborne-d <voidborne-d@users.noreply.github.com> |
