Erik Johnston	3ce8d59176	Increase cache size for _get_state_group_for_event	8 years ago
Erik Johnston	d58b1ffe94	Replace some calls to cursor_to_dict ... cursor_to_dict can be surprisinglh expensive for large result sets, so lets only call it when we need to.	8 years ago
Erik Johnston	e71940aa64	Use iter(items|values)	8 years ago
Erik Johnston	00957d1aa4	User Cursor.__iter__ instead of fetchall ... This prevents unnecessary construction of lists	8 years ago
Richard van der Hoff	0c01f829ae	Avoid resetting state on rejected events ... When we get a rejected event, give it the same state_group as its prev_event, rather than no state_group at all. This should fix https://github.com/matrix-org/synapse/issues/1935.	8 years ago
Erik Johnston	8ffbe43ba1	Get current state by using current_state_events table	8 years ago
Richard van der Hoff	fc2f29c1d0	Fix bugs in the /keys/changes api ... * `get_forward_extremeties_for_room` takes a numeric `stream_ordering`. We were passing a `RoomStreamToken`, which meant that it returned the *current* extremities, rather than those corresponding to the `from_token`. However: * `get_state_ids_for_events` required a second ('types') parameter; this meant that a `TypeError` was thrown and we ended up acting as though there was *no* prev state. * `get_state_ids_for_events` actually returns a map from event_id to state dictionary - just looking up the state keys in it again meant that we acted as though there was no prev state. We now check if each member's state has changed since *any* of the extremities. Also add/fix some comments.	8 years ago

Erik Johnston	897d57bc58	Change state fetch query for postgres to be faster ... It turns out that postgres doesn't like doing a list of OR's and is about 1000x slower, so we just issue a query for each specific type seperately.	8 years ago

Mark Haines	2a37467fa1	Use google style doc strings. ... pycharm supports them so there is no need to use the other format. Might as well convert the existing strings to reduce the risk of people accidentally cargo culting the wrong doc string format.	9 years ago
