SwitchingChannelSetDataSource

class SwitchingChannelSetDataSource(dbManager: DatabaseProvider, dispatchers: CoroutineDispatchers)(source)

Per-device channel-set storage backed by the current device's Room database.

Replaces the former single global channel_set.pb DataStore. The channel set now switches with DatabaseProvider.currentDb, exactly like messages and nodes, so switching between devices can no longer render one device's conversations against another device's channels (#4623).

The whole ChannelSet proto is stored in one row (see ChannelSetEntity); mutations are read-modify-write, so they are serialized through writeMutex to preserve the atomicity the old DataStore's updateData {} provided (the handshake fires overlapping updateChannelSettings calls as it downloads channels one by one).
