Python's asyncio event loop holds only weak references to tasks. Without a strong reference, the garbage collector can destroy a task while it's awaiting I/O — silently dropping messages. Python 3.12+ made this more aggressive. Audit of all gateway platform adapters found 6 untracked create_task calls across 6 files: Per-message tasks (tracked via _background_tasks set from base class): - gateway/platforms/webhook.py: handle_message task - gateway/platforms/sms.py: handle_message task - gateway/platforms/signal.py: SSE response aclose task Long-running infrastructure tasks (stored in named instance vars): - gateway/platforms/slack.py: Socket Mode handler (_socket_mode_task) - gateway/platforms/discord.py: bot client (_bot_task) - gateway/platforms/whatsapp.py: message poll loop (_poll_task, 2 sites) All other adapters (telegram, mattermost, matrix, email, homeassistant, dingtalk) already tracked their tasks correctly. Salvaged from PR #3160 by memosr — expanded from 1 file to 6.

Merged via PR #3267. Your fix was expanded to cover all 6 untracked asyncio.create_task() calls across the gateway — webhook, sms, signal, slack, discord, and whatsapp. Thanks for catching this! |

SmsAdapter and WebhookAdapter both call asyncio.create_task() without
storing the returned task reference. This is a known Python bug — tasks
not referenced elsewhere can be garbage collected mid-execution, silently
dropping messages.
BasePlatformAdapter already provides _background_tasks (a set) and the
correct add_done_callback pattern for task lifecycle management. This fix
applies the same pattern to both adapters.
