When the in-band pending-message drain spawns a fresh task and transfers ownership via _session_tasks[session_key] = drain_task, the original task still unwinds through the finally block. The drain task picks up the same interrupt_event in its own _process_message_background entry, so an unconditional _release_session_guard(session_key, guard=interrupt_event) at the end of the finally matches and deletes _active_sessions[session_key] while the drain task is still pending its first await. A concurrent inbound message arriving in that handoff window passes the Level-1 guard (no entry exists) and spawns a second _process_message_background for the same session — two agents on one session_key, duplicate responses, duplicate tool calls. Fix: only call _release_session_guard when the current task still owns _session_tasks[session_key]. When ownership has been transferred to a drain task, leave _active_sessions populated; the drain task's own lifecycle releases it. This mirrors the late-arrival drain path in the same finally block, which already leaves both entries alone after handing off. Also reorder stdlib imports in the new regression test file to match the gateway test convention (stdlib before third-party). Regression test: capture _active_sessions[sk] identity at every handler entry across a 2-step in-band drain chain and assert the guard Event identity stays the same. Pre-fix, the original task's finally deletes the entry, the drain task falls through to the `or asyncio.Event()` branch, and a fresh Event is installed — identity diverges. Post-fix, the entry is preserved and the drain task reuses the original Event. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
