asyncio holds only a weak reference to tasks returned by ``create_task``. Fire-and-forget callers that discard the return value let the event loop GC the task before it finishes, logging ``Task was destroyed but it is pending!`` with no traceback. The #1648 support-bundle review surfaced 94 such warnings in 8 days of v0.2.4.5 -- the silently-vanished exceptions reach support bundles as opaque GC notices instead of actionable errors. New backend/app/core/tasks.py::spawn_background_task(coro, *, name=None) is the one place in the codebase that calls asyncio.create_task. It stores the task in a module-level set, attaches a done-callback that auto-removes on completion AND surfaces any uncaught exception via the logger with the originating traceback, and accepts name= so a leak source is traceable through /tracebacks and the log line. Cancelled tasks don't log (a shutting-down service is not an error). Migrated the 16 truly-orphan create_task call sites to the helper: main.py (8): reconcile-stale, cooldown-poweroff, energy calc, smart-plug, maintenance-check, photo-then-notify, layer-timelapse, scan-timelapse, print-scheduler, notify-no-archive (the last one was hand-rolling the same pattern with task + no-op done_callback) printers.py:3123 apply-pa-after-refresh print_queue.py:1034 queue cooldown-poweroff firmware_update.py:261 firmware upload archive.py:1514 timelapse mp4 convert print_scheduler.py:2199 watchdog print-start library.py:1614 STL backfill smart_plugs.py:259 tasmota scan discovery.py:159 subnet scan smart_plug_manager.py x3 plug auto-off-pending background_dispatch.py x2 (lambda-wrapped inside loop.call_soon_threadsafe) upload progress Sites that already kept strong refs are unchanged: self._tasks.append(asyncio.create_task(...)) -- VP manager, tcp_proxy, mqtt_server self._x_task = asyncio.create_task(...) on service instances -- mqtt_bridge, obico_detection, github_backup, archive_purge, local_backup, library_trash, discovery service Locally assigned + awaited/gathered -- tcp_proxy bidirectional pumps, camera_fanout, slice_dispatch, slicer_api progress_task, manager._finish_release_task, main.py module-level cleanup loops |
