Two related race conditions in gateway/platforms/base.py that could produce duplicate agent runs or silently drop messages. Neither is specific to any one platform — all adapters inherit this logic. R5 (HIGH) — duplicate agent spawn on turn chain In _process_message_background, the pending-drain path deleted _active_sessions[session_key] before awaiting typing_task.cancel() and then recursively awaiting _process_message_background for the queued event. During the typing_task await, a fresh inbound message M3 could pass the Level-1 guard (entry now missing), set its own Event, and spawn a second _process_message_background for the same session_key — two agents running simultaneously, duplicate responses, duplicate tool calls. Fix: keep the _active_sessions entry populated and only clear() the Event. The guard stays live, so any concurrent inbound message takes the busy-handler path (queue + interrupt) as intended. R6 (MED-HIGH) — message dropped during finally cleanup The finally block has two await points (typing_task, stop_typing) before it deletes _active_sessions. A message arriving in that window passes the guard (entry still live), lands in _pending_messages via the busy-handler — and then the unconditional del removes the guard with that message still queued. Nothing drains it; the user never gets a reply. Fix: before deleting _active_sessions in finally, pop any late pending_messages entry and spawn a drain task for it. Only delete _active_sessions when no pending is waiting. Tests: tests/gateway/test_pending_drain_race.py — three regression cases. Validated: without the fix, two of the three fail exactly where the races manifest (duplicate-spawn guard loses identity, late-arrival 'LATE' message not in processed list). |
