From 458b6f473314a81d7e671fc2fc8c30d3259924c4 Mon Sep 17 00:00:00 2001 From: Erik Johnston Date: Tue, 31 Jan 2017 16:09:03 +0000 Subject: [PATCH] Only invalidate membership caches based on the cache stream Before we completely invalidated get_users_in_room whenever we updated any current_state_events table. This was way too aggressive. --- synapse/replication/resource.py | 3 --- synapse/replication/slave/storage/events.py | 21 +++++---------------- synapse/storage/events.py | 20 -------------------- synapse/storage/roommember.py | 2 -- 4 files changed, 5 insertions(+), 41 deletions(-) diff --git a/synapse/replication/resource.py b/synapse/replication/resource.py index a30e64747..d8eb14592 100644 --- a/synapse/replication/resource.py +++ b/synapse/replication/resource.py @@ -299,9 +299,6 @@ class ReplicationResource(Resource): "backward_ex_outliers", res.backward_ex_outliers, ("position", "event_id", "state_group"), ) - writer.write_header_and_rows( - "state_resets", res.state_resets, ("position",), - ) @defer.inlineCallbacks def presence(self, writer, current_token, request_streams): diff --git a/synapse/replication/slave/storage/events.py b/synapse/replication/slave/storage/events.py index b3f3bf748..15a025a01 100644 --- a/synapse/replication/slave/storage/events.py +++ b/synapse/replication/slave/storage/events.py @@ -192,10 +192,6 @@ class SlavedEventStore(BaseSlavedStore): return result def process_replication(self, result): - state_resets = set( - r[0] for r in result.get("state_resets", {"rows": []})["rows"] - ) - stream = result.get("events") if stream: self._stream_id_gen.advance(int(stream["position"])) @@ -205,7 +201,7 @@ class SlavedEventStore(BaseSlavedStore): for row in stream["rows"]: self._process_replication_row( - row, backfilled=False, state_resets=state_resets + row, backfilled=False, ) stream = result.get("backfill") @@ -213,7 +209,7 @@ class SlavedEventStore(BaseSlavedStore): self._backfill_id_gen.advance(-int(stream["position"])) for row in stream["rows"]: self._process_replication_row( - row, backfilled=True, state_resets=state_resets + row, backfilled=True, ) stream = result.get("forward_ex_outliers") @@ -232,20 +228,15 @@ class SlavedEventStore(BaseSlavedStore): return super(SlavedEventStore, self).process_replication(result) - def _process_replication_row(self, row, backfilled, state_resets): - position = row[0] + def _process_replication_row(self, row, backfilled): internal = json.loads(row[1]) event_json = json.loads(row[2]) event = FrozenEvent(event_json, internal_metadata_dict=internal) self.invalidate_caches_for_event( - event, backfilled, reset_state=position in state_resets + event, backfilled, ) - def invalidate_caches_for_event(self, event, backfilled, reset_state): - if reset_state: - self.get_rooms_for_user.invalidate_all() - self.get_users_in_room.invalidate((event.room_id,)) - + def invalidate_caches_for_event(self, event, backfilled): self._invalidate_get_event_cache(event.event_id) self.get_latest_event_ids_in_room.invalidate((event.room_id,)) @@ -267,8 +258,6 @@ class SlavedEventStore(BaseSlavedStore): self._invalidate_get_event_cache(event.redacts) if event.type == EventTypes.Member: - self.get_rooms_for_user.invalidate((event.state_key,)) - self.get_users_in_room.invalidate((event.room_id,)) self._membership_stream_cache.entity_has_changed( event.state_key, event.internal_metadata.stream_ordering ) diff --git a/synapse/storage/events.py b/synapse/storage/events.py index 6685b9da1..f4352b326 100644 --- a/synapse/storage/events.py +++ b/synapse/storage/events.py @@ -572,14 +572,6 @@ class EventsStore(SQLBaseStore): txn, self.get_users_in_room, (room_id,) ) - # Add an entry to the current_state_resets table to record the point - # where we clobbered the current state - self._simple_insert_txn( - txn, - table="current_state_resets", - values={"event_stream_ordering": max_stream_order} - ) - for room_id, new_extrem in new_forward_extremeties.items(): self._simple_delete_txn( txn, @@ -1610,15 +1602,6 @@ class EventsStore(SQLBaseStore): else: upper_bound = current_forward_id - sql = ( - "SELECT event_stream_ordering FROM current_state_resets" - " WHERE ?
