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".
Otherwise we risk blocking the dispatches on other work, and they
do not need to be done asynchronously.
This emerged as a bug where the room list appeared empty until
MatrixActions.sync dispatches all occured in one big lump, well
after the sync events being emitted by the js-sdk.
- Have TagOrderStore listen for MatrixSync actions so that it can initialise
tag ordering state.
- Expose an empty list until the client has done its first sync and has
fetched list of joined groups
This introduces a generic way to register certain events emitted by
the js-sdk as those that should be propagated through as dispatched
actions.
This allows the store to treat the js-sdk as the "Server" in the
Flux data flow model. It also allows for stores to not be aware
specifically of the matrix client if they are only reading from it.
