Eric Eastwood dd4be2453f Fix have_seen_event cache not being invalidated when we persist the event ... Fix for https://github.com/matrix-org/synapse/issues/13856 Fixed by calling `_invalidate_caches_for_event` when we persist an event. And an additional fix in `_invalidate_caches_for_event` to make sure it uses the correct cache key. This seems like it would be an easy foot-gun for any `tree=True` cache. Wrong: ```py self.have_seen_event.invalidate((room_id, event_id)) ``` Correct: ```py self.have_seen_event.invalidate(((room_id, event_id),)) ```		2022-09-21 15:45:08 -05:00
