There was a bug that meant we would return the full state of the room on incremental syncs when using lazy loaded members and there were no entries in the timeline. This was due to trying to use `state_filter or state_filter.all()` as a short hand for handling `None` case, however `state_filter` implements `__bool__` so if the state filter was empty it would be set to full. c.f.

"""Rooms shouldn't appear under "joined" if a join loses a race to a ban.
|
|
|
|
A complicated edge case. Imagine the following scenario:
|
|
|
|
* you attempt to join a room
|
|
* racing with that is a ban which comes in over federation, which ends up with
|
|
an earlier stream_ordering than the join.
|
|
* you get a sync response with a sync token which is _after_ the ban, but before
|
|
the join
|
|
* now your join lands; it is a valid event because its `prev_event`s predate the
|
|
ban, but will not make it into current_state_events (because bans win over
|
|
joins in state res, essentially).
|
|
* When we do a sync from the incremental sync, the only event in the timeline
|
|
is your join ... and yet you aren't joined.
|
|
|
|
The ban coming in over federation isn't crucial for this behaviour; the key
|
|
requirements are:
|
|
1. the homeserver generates a join event with prev_events that precede the ban
|
|
(so that it passes the "are you banned" test)
|
|
2. the join event has a stream_ordering after that of the ban.
|
|
|
|
We use monkeypatching to artificially trigger condition (1).
