From bec01c075829730cf467572e2fcf93e15372b0e9 Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Wed, 18 Aug 2021 09:22:07 -0400 Subject: [PATCH] Convert room member storage tuples to attrs. (#10629) Instead of using namedtuples. This helps with asserting type hints and code completion. --- changelog.d/10629.misc | 1 + synapse/handlers/initial_sync.py | 2 +- synapse/handlers/sync.py | 18 ++++---- synapse/storage/databases/main/roommember.py | 8 +++- .../storage/databases/main/user_directory.py | 2 +- synapse/storage/roommember.py | 45 ++++++++++++------- .../replication/slave/storage/test_events.py | 9 ++-- 7 files changed, 55 insertions(+), 30 deletions(-) create mode 100644 changelog.d/10629.misc diff --git a/changelog.d/10629.misc b/changelog.d/10629.misc new file mode 100644 index 000000000..cca1eb6c5 --- /dev/null +++ b/changelog.d/10629.misc @@ -0,0 +1 @@ +Convert room member storage tuples to `attrs` classes. diff --git a/synapse/handlers/initial_sync.py b/synapse/handlers/initial_sync.py index e1c544a3c..4e8f7f1d8 100644 --- a/synapse/handlers/initial_sync.py +++ b/synapse/handlers/initial_sync.py @@ -151,7 +151,7 @@ class InitialSyncHandler(BaseHandler): limit = 10 async def handle_room(event: RoomsForUser): - d = { + d: JsonDict = { "room_id": event.room_id, "membership": event.membership, "visibility": ( diff --git a/synapse/handlers/sync.py b/synapse/handlers/sync.py index eba915819..b7b299961 100644 --- a/synapse/handlers/sync.py +++ b/synapse/handlers/sync.py @@ -701,7 +701,7 @@ class SyncHandler: name_id = state_ids.get((EventTypes.Name, "")) canonical_alias_id = state_ids.get((EventTypes.CanonicalAlias, "")) - summary = {} + summary: JsonDict = {} empty_ms = MemberSummary([], 0) # TODO: only send these when they change. @@ -2076,21 +2076,23 @@ class SyncHandler: # If the membership's stream ordering is after the given stream # ordering, we need to go and work out if the user was in the room # before. - for room_id, event_pos in joined_rooms: - if not event_pos.persisted_after(room_key): - joined_room_ids.add(room_id) + for joined_room in joined_rooms: + if not joined_room.event_pos.persisted_after(room_key): + joined_room_ids.add(joined_room.room_id) continue - logger.info("User joined room after current token: %s", room_id) + logger.info("User joined room after current token: %s", joined_room.room_id) extrems = ( await self.store.get_forward_extremities_for_room_at_stream_ordering( - room_id, event_pos.stream + joined_room.room_id, joined_room.event_pos.stream ) ) - users_in_room = await self.state.get_current_users_in_room(room_id, extrems) + users_in_room = await self.state.get_current_users_in_room( + joined_room.room_id, extrems + ) if user_id in users_in_room: - joined_room_ids.add(room_id) + joined_room_ids.add(joined_room.room_id) return frozenset(joined_room_ids) diff --git a/synapse/storage/databases/main/roommember.py b/synapse/storage/databases/main/roommember.py index e8157ba3d..c2f6b9d63 100644 --- a/synapse/storage/databases/main/roommember.py +++ b/synapse/storage/databases/main/roommember.py @@ -307,7 +307,9 @@ class RoomMemberWorkerStore(EventsWorkerStore): ) @cached() - async def get_invited_rooms_for_local_user(self, user_id: str) -> RoomsForUser: + async def get_invited_rooms_for_local_user( + self, user_id: str + ) -> List[RoomsForUser]: """Get all the rooms the *local* user is invited to.
