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.

00957d1aa4 User Cursor.__iter__ instead of fetchall
This prevents unnecessary construction of lists

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.

8ffbe43ba1 Get current state by using current_state_events table 2017-03-10 17:39:35 +00:00

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.

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.

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.
