as everything listens to the dispatcher, dispatching an action can be quite slow,
especially when only matched in one listener, and the rest all having to be called
to just say "no, thanks". This is especially the case for the RoomMember.membership
event being put on the dispatcher, as there can be thousands of these events
when the room members are loading.
Since the RoomMember.membership action is only used on one place,
and only for the syncing user, change it to just that and only dispatch
in that case. This saves 100-300ms when setting the OOB members in
a big room (7000k members)
Maybe later on we can back this by room.getMyMembership() and avoid the
listener even...
Fix Riot's behaviour with room tags after my cleanup in
https://github.com/matrix-org/matrix-doc/pull/1457 . Although, reading
it again, it's not clear how you're supposed to tell the difference
between a reverse-dns tag name and a legacy freeform text tag
(contains a '.'?) - I've left it detecting these as freeform text
for now.
Previously we assumed that a decrypted event has a room_id
but this isn't necessarily true for to_device events.
It makes sense to ignore events that aren't associated with
rooms anyway given that the list we're updating only contains
rooms!
To make sure that we handle rooms that our
client has not seen previously, we regenerate
the room list when the room is stored -
which is indicated by the js-sdk by the
Room event.
so that we can do reorderings of lists ordered by most recent event.
No optimisations here; we only update for timeline events
on live timelines that could update the "unread count".
Actually fixes vector-im/riot-web#6135 unlike #1748, which
incorrectly assumed that custom tags would be included in
listOrders.
This fix makes sure that the `default` case in the `switch`
is actually used.
