Legacy sync cleanup, removal of legacy SS #1132
2025-12-03
fix: Use
prepare_lazily_loaded_members for joined rooms
Also, don't take read receipts into consideration for lazy loading. Synapse doesn't do this and they're making initial syncs very large.
feat: Typing notifications in simplified sliding sync
What's missing? Being able to use separate rooms & lists for typing indicators. At the moment, we use the same ones as we use for the timeline, as todo_rooms is quite intertwined. We need to disentangle this to get that functionality, although I'm not sure if clients use it.
fix: Properly sync left rooms
- Remove most usages of `update_membership` in favor of directly calling the `mark_as_*` functions - Store the leave membership event as the value in the `userroomid_leftstate` table - Use the `userroomid_leftstate` table to synchronize the timeline and state for left rooms if possible
