The module-global `_loop` / `_loop_thread` pair is shared across every `HindsightMemoryProvider` instance in the process — the plugin loader creates one provider per `AIAgent`, and the gateway creates one `AIAgent` per concurrent chat session (Telegram/Discord/Slack/CLI). `HindsightMemoryProvider.shutdown()` stopped the shared loop when any one session ended. That stranded the aiohttp `ClientSession` and `TCPConnector` owned by every sibling provider on a now-dead loop — they were never reachable for close and surfaced as the `Unclosed client session` / `Unclosed connector` warnings reported in #11923. Fix: stop stopping the shared loop in `shutdown()`. Per-provider cleanup still closes that provider's own client via `self._client.aclose()`. The loop runs on a daemon thread and is reclaimed on process exit; keeping it alive between provider shutdowns means sibling providers can drain their own sessions cleanly. Regression tests in `tests/plugins/memory/test_hindsight_provider.py` (`TestSharedEventLoopLifecycle`): - `test_shutdown_does_not_stop_shared_event_loop` — two providers share the loop; shutting down one leaves the loop live for the other. This test reproduces the #11923 leak on `main` and passes with the fix. - `test_client_aclose_called_on_cloud_mode_shutdown` — each provider's own aiohttp session is still closed via `aclose()`. Fixes #11923. |
