From ac11fcbbb8ccfeb4c72b5aae9faef28469109277 Mon Sep 17 00:00:00 2001 From: Erik Johnston Date: Thu, 24 Sep 2020 13:24:17 +0100 Subject: Add EventStreamPosition type (#8388) The idea is to remove some of the places we pass around `int`, where it can represent one of two things: 1. the position of an event in the stream; or 2. a token that partitions the stream, used as part of the stream tokens. The valid operations are then: 1. did a position happen before or after a token; 2. get all events that happened before or after a token; and 3. get all events between two tokens. (Note that we don't want to allow other operations as we want to change the tokens to be vector clocks rather than simple ints) --- synapse/handlers/federation.py | 16 ++++++++++------ 1 file changed, 10 insertions(+), 6 deletions(-) (limited to 'synapse/handlers/federation.py') diff --git a/synapse/handlers/federation.py b/synapse/handlers/federation.py index ea9264e751..9f773aefa7 100644 --- a/synapse/handlers/federation.py +++ b/synapse/handlers/federation.py @@ -74,6 +74,8 @@ from synapse.storage.databases.main.events_worker import EventRedactBehaviour from synapse.types import ( JsonDict, MutableStateMap, + PersistedEventPosition, + RoomStreamToken, StateMap, UserID, get_domain_from_id, @@ -2956,7 +2958,7 @@ class FederationHandler(BaseHandler): ) return result["max_stream_id"] else: - max_stream_id = await self.storage.persistence.persist_events( + max_stream_token = await self.storage.persistence.persist_events( event_and_contexts, backfilled=backfilled ) @@ -2967,12 +2969,12 @@ class FederationHandler(BaseHandler): if not backfilled: # Never notify for backfilled events for event, _ in event_and_contexts: - await self._notify_persisted_event(event, max_stream_id) + await self._notify_persisted_event(event, max_stream_token) - return max_stream_id + return max_stream_token.stream async def _notify_persisted_event( - self, event: EventBase, max_stream_id: int + self, event: EventBase, max_stream_token: RoomStreamToken ) -> None: """Checks to see if notifier/pushers should be notified about the event or not. @@ -2998,9 +3000,11 @@ class FederationHandler(BaseHandler): elif event.internal_metadata.is_outlier(): return - event_stream_id = event.internal_metadata.stream_ordering + event_pos = PersistedEventPosition( + self._instance_name, event.internal_metadata.stream_ordering + ) self.notifier.on_new_room_event( - event, event_stream_id, max_stream_id, extra_users=extra_users + event, event_pos, max_stream_token, extra_users=extra_users ) async def _clean_room_for_join(self, room_id: str) -> None: -- cgit 1.5.1
