This PR adds a gomatrixserverlib.Filter parameter to functions handling the syncapi_current_room_state table. It does not implement any filtering logic inside the syncapi IncrementalSync/CompleteSync functions, just the APIs for future use. Default filters are provided as placeholders in IncrementalSync/CompleteSync, so behaviour should be unchanged (except the default 20 event limit) SQL table will be changed. You can upgrade an existing database using: ``` ALTER TABLE syncapi_current_room_state ADD COLUMN IF NOT EXISTS sender text; UPDATE syncapi_current_room_state SET sender=(event_json::json->>'sender'); ALTER TABLE syncapi_current_room_state ALTER COLUMN sender SET NOT NULL; ALTER TABLE syncapi_current_room_state ADD COLUMN IF NOT EXISTS contains_url bool; UPDATE syncapi_current_room_state SET contains_url=(event_json::json->>'content')::json->>'url' IS NOT NULL; ALTER TABLE syncapi_current_room_state ALTER COLUMN contains_url SET NOT NULL; ``` Note: This depends on #436 (and includes all its commits). I'm not sure if Github will remove the duplicated commits once #436 is merged.
