Integratation within the sync lifetime cycle

session.prepareSync

Decrypt any device messages, and turn them into RoomKey instances. Any rooms that are not in the sync response but for which we receive keys will be included in the rooms to sync.

Runs before any room.prepareSync, so the new room keys can be passed to each room prepareSync to use in decryption.

room.prepareSync

The session can start its own read/write transactions here, rooms only read from a shared transaction

- rooms (with shared read txn)
    - megolm decryption read using any new keys decrypted by the session.

room.afterPrepareSync

- rooms    
    - megolm async decryption   
        - dispatch to worker

room.writeSync

- rooms (with shared readwrite txn)
    - megolm decryption write, yielding decrypted events
    - use decrypted events to write room summary

session.writeSync

  • writes any room keys that were received

room.afterSync

- rooms
    - emit changes

room.afterSyncCompleted

- session
    - e2ee account
        - generate more otks if needed
        - upload new otks if needed or device keys if not uploaded before
- rooms
    - share new room keys if needed
