**This option is not recommended as it completely obliterates all chances of being able to support someone with a broken room list. It is intended for specific testing scenarios only.**
The room list does a hefty amount of work, so instead of blocking the event loop with a `/sync` request and a bunch of room updates (as we can get multiple per sync) we can instead run it over several smaller tasks. The smaller tasks help the event loop do other things between our tasks, ensuring we don't inadvertently block the UI from rendering too slowly.
On my account and machine, this cuts the time to render in half (~30ms, down from ~60ms) .
The core of this is in the MarkedExecution class, with the remainder of the commit ensuring that the right marks and triggers are in place to do the firing.
Because everything is async/await and run through the RoomListStore, we don't have to worry about self-fed updates in the algorithm classes. This also means we have to trigger pretty much all the time.
Changes to tag ordering / list sorting get hit through two paths, so we mark before we do a bulk update and otherwise assume the call is coming in from outside.
Known issues:
* Causes scroll jumps when the button gets added to DOM
* Resize handle is invisible when there's a show more button
TODO:
* Clean up comments
* Clean up useless code (all the padding stuff isn't needed)
For new rooms, we need to append to our list of known rooms. For tag changes, we need to be sure to update our cache when the tag can reasonably be assumed to have changed.

We were receiving a read receipt before a room object, leading to the algorithm to assume the room is archived (no membership), which was causing later index issues when the room tried to get moved from archived to untagged.
To prevent this, we just ignore nonsensical updates.
Previously we were creating a notification state whenever we needed one, which was leading to hundreds of listeners even on a small account. To ease the burden, and reduce the load of having to wake so many listeners, we now record a single listener for each tag ID and room combination.
This commit also introduces a number of utilities to make future notification work a bit of an easier transition, such as the `isX` and `hasX` getters on the new NotificationState abstract class. Similarly, "snapshots" have been added to reduce code duplication between different kinds of states checking for updates.
The ListNotificationState is now heavily tied into the store which offers it to help reuse the cache of room notification states.

This is more general maintenance than performance as the RoomList doesn't need to be generating layouts for the sublists, and it certainly doesn't need to be creating a bunch of extra ones.
The sublists are perfectly capable of getting their own layout instance and using it, and we are perfectly able to limit the number of these things we create through the session's lifespan.
In this demonstration, we remove the cutting line (as it collides with the tile in a weird spot) and instead replace the tile with a placeholder when the text is about to collide with the avatar in the tile. We use a `round()` for this because through some amazing coincidence the collision happens at 0.47, which is close enough to 0.5 for people not to notice.
Fixes https://github.com/vector-im/riot-web/issues/14378
Rooms transitioning between multiple states are often at risk of going missing due to the sticky room handling. We now protect that transition by bluntly ensuring the room can't go missing, and by always ensuring we have an updated reference to the room.
react-resizer appears to be okay at tracking state, but it often desyncs from reality. re-resizer is more maintained and more broadly used (160k downloads vs 110k), and appears to generally do a better job of tracking the cursor.
The new library has some oddities though, such as deltas, touch support (hence the polyfill), and calling handles "Enable".

We don't need the fake clock anymore, but we do have to wait for async actions to complete before moving forward.
This also exposes a number of functions for the store to be puppetted with.

We read/use the options in multiple places, and those places were not in sync. Now when algorithms change and on initial load, both will come to the same conclusions about how to order & sort the rooms.
This fixes a case where a user accepts an invite, which causes a tag change, but the room stays stuck in the invites list. The tag change additionally gets swallowed when the user moves away, causing the room to get lost.
By moving it when we see it, potentially during a sticky room change itself (though extremely rare), we avoid having the room get lost in the wrong lists. A side effect of this is that accepting an invite puts it at the top of the tag it's going to (usually untagged), however this feels like the best option for the user.
A rare case of a tag change happening during a sticky room change is when a leave event comes in for the sticky room, but because it's come through as a tag change it can get swallowed. If it does get swallowed and the user clicks away, the tag change will happen when the room is re-introduced to the list (fake NewRoom event).
Plus a bunch of logging.
This fixes a case where switching rooms would cause the last room you were on to disappear due to an optimization where known NewRoom fires would be translated to tag change fires, which wouldn't re-add the room to the underlying tag algorithm.
By tracking the last sticky room, we can identify when we're about to do this and avoid it.
This commit also adds a check to ensure that we have the latest reference of a room stored as rooms changing from invite -> join change references.
This commit additionally updates the PossibleTagChange handling to be faster and smarter, leading to a more stable generation of the room list. We convert the update cause to a Timeline update in order to indicate it is a change within the same tag rather than having to jump tags. This also means that PossibleTagChange should no longer make it as far as the underlying algorithm.
New logging has also been added to aid debugging.

Disclaimer: this is all of the horrible because it's not meant to be here. Invites in general are likely to move out of the room list, which means this is temporary. Additionally, the communities rework will take care of this more correctly. For now, we support the absolute bare minimum to have them shown.
For example, if you only have 3/10 rooms required for the default then resize smaller, we should have a 'show more' button.
This works by changing the rendering to be slightly more efficient and only looping over what is seen (renderVisibleTiles(), using this.numTiles in place of tiles.length) and using a new setVisibleTilesWithin() function on the layout. Previously resizing the 3/10 case would be setting visibleTiles to ~8 instead of ~1 like it should (because the getter returns a default).
`setKnownRooms` is called to regenerate the room list, and if we don't take the sticky room out of the equation we end up with the room being duplicated. So, to make this easy, we simply remove the sticky room and handle it after the fact.
This small check just ensures that we aren't about to blindly accept that the calling code knows what it is doing. There are some unknown cases where NewRoom gets fired for rooms we already know about, so in those cases we just change it to a PossibleTagChange which is what the caller likely intended.
Many of the edge cases are unknown, though this can happen for an invite being accepted (for example). It's easier to handle it here instead of tracking down every single possibility and fixing it higher up.
When a new room is added there's a fairly good chance that the other events being dispatched will happen in the middle of (for example) the room list being re-sorted. This commit wraps the entire handleRoomUpdate() function for the underlying algorithms in a lock so that if we're unlucky enough to get an update while we're sorting (as the ImportanceAlgorithm splices out what it is sorting) we won't scream about invalid index errors.
We have to do a bit of a dance to return the sticky room to the list so we can remove it, if needed, and ensure that we generally swap the rooms out of the list.
This reverts earlier changes made to textForEvent as they are no longer needed.
This also implements an entire tree of textForEvent-like behaviour as the previews need to be different, which is easiest done with its own stack.
Smaller handle width, small shadow on the top of the show more button if there's more rooms to be shown. The resize handle also only shows when you're hovering in the area now.
The original design called for the shadow to show up only if the user is cutting a tile or dragging, however that is complicated implementation-wise. For speed and encouraging a dogfooding pattern we're going ahead with this behaviour instead.

One of the largest issues with room switching was that we'd regenerate the entire list when the sticky room changes, which is obviously detrimental on larger accounts (and even some medium accounts). To work through this, we simply handle the NewRoom and RoomRemoved causes (used by the sticky room handling) as splices rather than in-place updates.
Overall this leads to a smoother experience as it means we're doing far less calculations and can even opt out of an update if it isn't required, such as a RoomRemoved cause being fired twice - the second one can result in an update not being required, saving render time.
This commit also includes a fix for handling update causes on the sticky room, as the room list loves to print errors when this happens. We don't need to handle any updates because once the sticky room changes it'll get re-added through NewRoom, causing the underlying algorithm to slot it in where needed, effectively handling all the missed updates.
When the user would click 'show more' they would be presented with a 'show less' button that occluded the last room.
Similarly, if they resized the list so that all their rooms would be shown and refreshed the page, they would find their last room covered by the button.
This changes the handling so that showAllClick() sets the height to numTiles + button padding, and adjusts the height calculations on render to deal with relative tiles.
This also removes the conditional padding of the resize handle, as we always occupy the 4px of space. It was leading to rooms getting trimmed slightly by the show N button.
This commit is a bit involved, as it factors the tag specific handling out of `/list-ordering` (and moves the `Algorithm` class one higher as a result), leaving it in the `Algorithm`. The algorithms for list ordering now only know how to handle a single tag, and this is managed by the `Algorithm` class - which is also no longer the base class for the list ordering. The list ordering algorithms now inherit from a generic `OrderingAlgorithm` base class which handles some rudimentary things.
Overall the logic hasn't changed much: the tag-specific stuff has been moved into the `Algorithm`, and the list ordering algorithms essentially just removed the iteration on tags. The `RoomListStore2` still shovels a bunch of information over to the `Algorithm`, which can lead to an awkward code flow however this commit is meant to keep the number of surfaces touched to a minimum.
The RoomListStore has also gained the ability to set per-list (tag) ordering and sorting, which is required for the new room list. The assumption that it defaults from the account-level settings is not reviewed by design, yet. This decision is deferred.
The 'sort by' radio buttons are blocked by https://github.com/matrix-org/matrix-react-sdk/pull/4731 as it contains the styles needed.
The 'unread rooms' checkbox is intentionally not hooked up. This is a more complicated refactoring that needs to be done.
The message preview checkbox works, though the previews remain hardcoded in this change. The primary intent of this change is to have a good enough context menu and the hover states.
The hover states are as described in the design.
This is to fix an issue where when using both the community filter panel and the search box it's an AND rather than further refining the results.
This makes the search box further refine the community filter panel results.
This all-new component handles breadcrumbs a bit more smoothly for the app by always listening to changes even if the component isn't present. This allows the breadcrumbs to remain up to date for when the user re-enables breadcrumbs.
The new behaviour is that we turn breadcrumbs on once the user has a room, and we don't turn it back off for them.
This also introduces a new animation which is more stable and not laggy, though instead of sliding the breadcrumbs pop. This might be undesirable - to be reviewed.

This adds support for:
* Tag changes
* DM changes
* Marking our own rooms as read
* Our own membership changes
The remaining branch we didn't need was the alternate 'new room' branch, so it was removed.
This is not optimized - optimization is deferred.
Originally this was intended to be done only in the importance algorithm, however it is clear that all algorithms will need to deal with this. As such, it has been put into the base class to deal with as we may override it in the future.
This commit should be self-documenting enough to describe what is going on, though the major highlight is that the handling of the sticky room is done by lying to the underlying algorithm.
This has not been optimized for performance yet.

This is an incomplete implementation and is mostly dumped in this state for review purposes. The remainder of the features/bugs are expected to be in more bite-sized chunks.
This exposes the RoomListStore on the window for easy access to things like the new filter functions (used in debugging).
This also adds initial handling of "new rooms" to the client, though the support is poor.
Known bugs:
* [ ] Regenerates the entire room list when a new room is seen.
* [ ] Doesn't handle 2+ filters at the same time very well (see gif. will need a priority/ordering of some sort).
* [ ] Doesn't handle room order changes within a tag yet, despite the docs implying it does.
Sorting and ordering has now been split apart. The ImportanceAlgorithm also finally makes use of the sorting.
So far metrics look okay at 3ms for a simple account, though this could potentially get worse due to the multiple loops involved (one for tags, one for categories, one for ordering). We might be able to feed a whole list of rooms into the thing and have it regenerate the lists on demand.
This is the fruits of about 3 attempts to write code that works. None of those attempts are here, but how edition 4 could work is at least documented now.
This is to get around the problem of a slow dispatch loop. Instead of slowing the whole app down to deal with room lists, we'll just raise events to say we're ready.
Based upon the EventEmitter class.
This does a number of things (sorry):
* Estimates the type changes needed to the dispatcher (later to be replaced by https://github.com/matrix-org/matrix-react-sdk/pull/4593)
* Sets up the stack for a whole new room list store, and later components for usage.
* Create a proxy class to ensure the app still functions as expected when the various stores are enabled/disabled
* Demonstrates a possible structure for algorithms
If you clicked on the header button whilst the right panel was
showing a room member, it would NPE because there was no
refireParams.member. It fires the same phase with no refireParams to
toggle the panel visibility (apparently), so detect that case.

Wait for our user to become verified and cross-signing to be ready
before declaring that we're finsihed, otherwise we could end up
prompting the user to verify again if we just wait for the verification
itself to complete.

All the update triggers for the RoomListStore go through the `setRoomCategory` function, so by returning early we're not actually calculating where a room should be in the list.
To store toast. Rather than them being stored in the state of the
ToastContainer component, they now have a dedicated store. This mostly
fixes problems involving showing toasts when the app loaded because
we would otherwise have a race condition where something tries to
show a toast before the ToastContainer is mounted.
We use `export default` begrudgingly here. Ideally we'd use just `export`, though this entire SDK expects things to be exported as a default. Instead of breaking everything, we'll sacrifice our export pattern for a smaller diff - a later commit can always do the default export -> regular export conversion.
Fixes https://github.com/vector-im/riot-web/issues/11663
Member info is special because it has parameters associated with it. What was happening was the RightPanelStore was seeing that it was already on member info and deciding to hide the pane instead. What we do now is consider any phase change with parameters (such as the user to pass to member info) as a proper phase change.
Clicking on the member icon was fine, but clicking on the file panel wouldn't bring it up - it had to be clicked a second time to actually show the panel.
This lays a foundation for redirecting all the traffic through the new store, but for now the core parts of the app need to stop caring if the right panel is open.
Zero inserts is not normal, so we apply the same recovery technique from the categorization logic above this block: insert it to be the very first room and hope that someone complains that the room is ordered incorrectly.
There's some additional logging to try and identify what went wrong because it should definitely be inserted. The `!== 1` check is not supposed to be called, ever.

This adds very basic cache (literally just a `Map` for now) to store room alias
to room ID mappings. The improves the perceived performance of Riot when
switching rooms via browser navigation (back / forward), as we no longer try to
resolve the room alias every time.
The cache is only in memory, so reloading manually or as part of the clear cache
process will start afresh.

This implementation reuses as much of the Lifecycle flow as it can without causing problems. Most importantly, it requires https://github.com/matrix-org/matrix-js-sdk/pull/975 to be able to detect a soft logout and react to it. When it comes time to starting/stopping the Lifecycle, additional parameters are provided so that the auxiliary services can (re)start themselves without the client starting to sync.
