Features
- The stream tokens for
/synchave been refactored, giving PDUs, typing notifications, read receipts, invites and send-to-device messages their own respective stream positions, greatly improving the correctness of sync - A new roominfo cache has been added, which results in less database hits in the roomserver
- Prometheus metrics have been added for sync requests, destination queues and client API event send perceived latency
Fixes
- Event IDs are no longer recalculated so often in
/sync, which reduces CPU usage - Sync requests are now woken up correctly for our own device list updates
- The device list stream position is no longer lost, so unnecessary device updates no longer appear in every other sync
- A crash on concurrent map read/writes has been fixed in the stream token code
- The roomserver input API no longer starts more worker goroutines than needed
- The roomserver no longer uses the request context for queued tasks which could lead to send requests failing to be processed
- A new index has been added to the sync API current state table, which improves lookup performance significantly
- The client API
/joined_roomsendpoint no longer incorrectly returnsnullif there are 0 rooms joined - The roomserver will now query appservices when looking up a local room alias that isn't known
- The check on registration for appservice-exclusive namespaces has been fixed
