This patch adds a new `cancel_in_flight_request` argument to
`SlidingSync::subscribe_to_rooms`, which tells the method cancel the
in-flight request if any.
This patch also updates `RoomListService::subscribe_to_rooms` to turn
this new argument to `true` if the state machine isn't in a “starting”
state.
The problem it's solving is the following:
* some apps starts the room list service
* a first request is sent with `pos = None`
* the server calculates a new session (which can be expensive)
* the app subscribes to a set of rooms
* a second request is immediately sent with `pos = None` again
* the server does possibly NOT cancel its previous calculations, but
starts a new session and its calculations
This is pretty expensive for the server. This patch makes so that the
immediate room subscriptions will be part of the second request, with
the first request not being cancelled.
This method is now private inside `matrix_sdk_ui` and removed
from `matrix_sdk_ffi`. This method is returning a stream of rooms,
but updates on rooms won't update the stream (only new rooms
will be seen on the stream). Nobody uses it as far as I know, and
`entries_with_dynamic_adapters` is the real only API we want people
to use.
This field is helpful as it tells us the sequence number of the message in the
megolm session, which gives us a clue about how long it will have been since
the session should have been shared with us.
This fn will loop until it finds an at least partially synced room with the given id. It uses the `ClientInner::sync_beat` listener to wait until the next check is needed.
This patch adds `m.room.canonical_name` in the `required_state` of the
`all_rooms` list defined by `RoomListService`.
This is useful to better compute the room name in a more robust way.
## Changes
Takes care of [this
TODO](9df1c48079/crates/matrix-sdk-ui/src/timeline/mod.rs (L520)).
- sdk & sdk-ui: unify `Timeline::edit` and `Timeline::edit_polls`, the
new fn takes an `EditedContent` parameter now, which includes a
`PollStart` case too.
- ffi: also unify the FFI fns there, using `PollStart` and a new
`EditContent` enum that must be passed from the clients like:
```kotlin
val messageContent = MessageEventContent.from(...)
timeline.edit(event, EditedContent.RoomMessage(messageContent))
```
Since the is mainly about changing the fns signatures I've reused the
existing tests, including one that used `edit_poll` that now uses the
new fn.

There is a non-negligible difference MSC3575 and MSC4186 in how the
`e2ee` extension works. When the client sends a request with no `pos`:
* MSC3575 returns all device lists updates since the last request
from the device that asked for device lists (this works similarly to
to-device message handling),
* MSC4186 returns no device lists updates, as it only returns changes
since the provided `pos` (which is `null` in this case); this is in
line with sync v2.
Therefore, with MSC4186, the device list cache must be marked as to be
re-downloaded if the `since` token is `None`, otherwise it's easy to
miss device lists updates that happened between the previous request and
the new “initial” request.
This patch adds the `OldMachine::mark_all_tracked_users_as_dirty`.
This patch rewrites a bit `OlmMachine::new_helper` by extracting some
piece of it inside `OlmMachine::new_helper_prelude`. With that, we
can rewrite `OlmMachine::migration_post_verified_latch_support` to use
`IdentityManager::mark_all_tracked_users_as_dirty`.
This latter is the shared implementation with
`OlmMachine::mark_all_tracked_users_as_dirty`.
This patch adds a test for `OlmMachine:mark_all_tracked_users_as_dirty`.
This patch improves `Client::available_sliding_sync_versions` when
trying to detect the sliding sync proxy. Previously, we were relying
on the `Client::server` to send the `discover_homeserver::Request`.
Sadly, this value is an `Option<_>`, meaning it's not always defined
(it depends how the `Client` has been built with `HomeserverConfig`:
sometimes the homeserver URL is passed directly, so the server cannot
be known).
This patch tries to find to discover the homeserver by using
`Client::server` if it exists, like before, but it also tries by using
`Client::user_id`. Another problem arises then: the user ID indeed
contains a server name, but we don't know whether it's behind HTTPS or
HTTP. Thus, this patch tries both: it starts by testing with `https://`
and then fallbacks to `http://`.
A test has been added accordingly.
The term session is usually only used in the crypto crate to reference a
Megolm session, the rest of the SDK uses the name from the event and the
Matrix spec, this should lower the amount of confusion since the main
crate has already a session concept and its unrelated to end-to-end
encryption.
