fix(gateway): track background task references in GatewayRunner - #3254
Merged
Conversation
Asyncio tasks created with create_task() but never stored can be garbage collected mid-execution. Add self._background_tasks set to hold references, with add_done_callback cleanup. Tracks: - /background command task - session-reset memory flush task - session-resume memory flush task Cancel all pending tasks in stop(). Update test fixtures that construct GatewayRunner via object.__new__() to include the new _background_tasks attribute. Cherry-picked from PR #3167 by memosr. The original PR also deleted the DM topic auto-skill loading code — that deletion was excluded from this salvage as it removes a shipped feature (#2598).

Summary
Salvage of PR #3167 by @memosr, cherry-picked onto current main.
What this fixes
Fire-and-forget
asyncio.create_task()calls without stored references are vulnerable to garbage collection silently canceling the task mid-execution. This adds aself._background_tasksset toGatewayRunnerusing the standardadd_done_callback(discard)pattern.Tasks now tracked:
/backgroundcommand taskCleanup on shutdown:
stop()cancels all pending background tasks before clearing adapters.What was excluded from the original PR
The original PR also deleted ~30 lines of DM topic auto-skill loading code (shipped in #2598) without explanation. That deletion was excluded from this salvage.
Test fixes
Three test files construct
GatewayRunnerviaobject.__new__()bypassing__init__. Updated their fixtures to include the new_background_tasksattribute.Gateway suite: 1461 passed, 21 skipped.
Closes #3167
