This opens up a possible race condition where an embedder calls the method twice, generating two new rooms,
but then it's fine as long as they don't cache them somewhere, which we expect they don't.
That avoids recreating a timeline object every time a user calls `RoomListService::room()` with the same room id, so that should speed up
operations like fetching the latest event for rooms we've already entered before.
This patch changes the capacity of the internal buffer of
`ObservableVector` for `SlidingSyncList::room_list` from 16 to 4096.
With an increased capacity, we reduce the probability to send a
`VectorDiff::Reset` to subscribers. `Reset` are happening quite often
for apps using `matrix-sdk`, and it impacts their performance. This
patch tries to improve this situation. This `room-list` contains
`RoomListEntry`, which is can cheap in terms of memory, compared to the
impact of sending `Reset`s too often. That's a tradeoff.
* bindings: Ignore silently malformed userId in migration of tracked users
* Clean: collect will now never fail
Co-authored-by: Benjamin Bouvier <public@benj.me>
* crypto: implement more primitives for the MemoryStore to work in tests
* crypto: change the shape of the `CryptoStoreLock` API
In particular:
- make the lock work across multiple threads of the same process trying to acquire it,
using `num_holders`.
- add a mechanism to get the lock only once (for the NSE process, in case the main app
had acquired the lock before).
* client: add a cross-process crypto store lock, enable it with `Encryption::enable_cross_process_store_lock`
* client: make `preshare_room_key` a critical section of the cross-process lock
* sliding sync: make it possible to define different timeouts for a `SlidingSyncInstance`
This will be handy for the NSE process on iOS, which has very little time to wait for the proxy's responses.
* feat: implement the `EncryptionSync` API (renamed from `Notification` API)
* fixup! client: add a cross-process crypto store lock, enable it with `Encryption::enable_cross_process_store_lock`
* feat: allow disabling e2ee / to-device in the RoomList API
* feat: use same SS id for main/NSE process, reload to-device token from disk before each encryption sync
* fix: better error handling if restoring the to-device token failed
* feat: add logs for the locking functions
* test: add a few tests for encryption sync
* feat: add `reload_caches` method in the `EncryptionSync` + FFI bindings
* chore: clean up FFI loop
* encryption sync: Remove unused errors, specialize some errors
* feat: include termination reason in the encryption sync loop
* feat: add more logs
* chore: fmt + clippy + doc
* comment: precise only in the presence of another process
* Tweak `room_list` APIs to include `_with_encryption` variants
* chore: rustfmt
