When we load the page, all encrypted events arrive well after we've generated our initial grouping which can cause them to jump to the top of their categories wrongly. For direct chats, this meant that people who don't have a lot of unread messages would see ancient rooms bubbling to the top for no reason after the page has loaded.
We still have to track when the last category change was (ie: when we switched from red -> grey) so that when the category doesn't exist in the list we can insert the room at the right place (the start of the last category when we switch beyond the order expected).
This changes the approach from regenerating every time there's a change to incrementally fixing the room lists. Additionally, this forces the pin options on for people and implements the sticky room behaviour.
Known bugs include newly joined rooms, invites, etc not sorting correctly.
This takes out the old user and room settings, replacing the paths with the new dialog editions. The labs setting has been removed in order to support this change.
In addition to removing the old components outright, some older components which were only used by the settings pages have been removed. The exception is the ColorSettings component as it has a high chance of sticking around in the future.
Styles that were shared by the settings components have been broken out to dedicated sections, making it easier to remove the old styles entirely.
Some stability testing of the app has been performed to ensure the app still works, however given the scope of this change there is a possibility of some broken functionality.
This is intentionally not removing the labs flag or other supporting structures of the old settings to make a revert as easy as possible in the event that needs to happen. All of the cruft left behind (TempTab, temp styles, labs flag, old components, etc) will be removed in the very near future.
`unread` and `unread-muted` store booleans in the cache, and can easily be `false`. Without this patch, both of those cached types would be cleared from the object where a later call to `getRoomState` would try and re-populate them. `getRoomState` is supposed to use the cache where possible to avoid making the more expensive calls required to calculate those booleans.
On my account in a test environment, this brings the `generateRoomLists` execution time down from ~250ms to just ~30ms.
This still does not solve the whole issue, but should solve the more common case of performance woes for people.
the idea is that it will keep a RoomViewStore for every
room on the screen, and also keep track of which one is
the current one.
For now, it just replicates the existing functionality of
having just 1 room on the screen.
Since the RoomViewStore just has access to a local dispatcher
and not the global anymore, all dispatching of actions
needs to be moved to the OpenRoomsStore, so room alias resolving,
event forwarding, ... is moved there.
