From 80e0e1f35e6b1cdfa0267f9c40a6f212b7d774de Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Fri, 18 Mar 2022 13:15:45 -0400 Subject: [PATCH] Only fetch thread participation for events with threads. (#12228) We fetch the thread summary in two phases: 1. The summary that is shared by all users (count of messages and latest event). 2. Whether the requesting user has participated in the thread. There's no use in attempting step 2 for events which did not return a summary from step 1. --- changelog.d/12228.bugfix | 1 + synapse/storage/databases/main/relations.py | 4 +- tests/rest/client/test_relations.py | 509 +++++++++++--------- tests/server.py | 20 +- 4 files changed, 289 insertions(+), 245 deletions(-) create mode 100644 changelog.d/12228.bugfix diff --git a/changelog.d/12228.bugfix b/changelog.d/12228.bugfix new file mode 100644 index 0000000000..4755777139 --- /dev/null +++ b/changelog.d/12228.bugfix @@ -0,0 +1 @@ +Fix a bug introduced in v1.53.0 where an unnecessary query could be performed when fetching bundled aggregations for threads. diff --git a/synapse/storage/databases/main/relations.py b/synapse/storage/databases/main/relations.py index c4869d64e6..af2334a65e 100644 --- a/synapse/storage/databases/main/relations.py +++ b/synapse/storage/databases/main/relations.py @@ -857,7 +857,9 @@ class RelationsWorkerStore(SQLBaseStore): summaries = await self._get_thread_summaries(events_by_id.keys()) # Only fetch participated for a limited selection based on what had # summaries. - participated = await self._get_threads_participated(summaries.keys(), user_id) + participated = await self._get_threads_participated( + [event_id for event_id, summary in summaries.items() if summary], user_id + ) for event_id, summary in summaries.items(): if summary: thread_count, latest_thread_event, edit = summary diff --git a/tests/rest/client/test_relations.py b/tests/rest/client/test_relations.py index f3741b3001..329690f8f7 100644 --- a/tests/rest/client/test_relations.py +++ b/tests/rest/client/test_relations.py @@ -15,7 +15,7 @@ import itertools import urllib.parse -from typing import Any, Dict, List, Optional, Tuple +from typing import Any, Callable, Dict, List, Optional, Tuple from unittest.mock import patch from twisted.test.proto_helpers import MemoryReactor @@ -155,6 +155,16 @@ class BaseRelationsTestCase(unittest.HomeserverTestCase): self.assertEqual(200, channel.code, channel.json_body) return channel.json_body["chunk"] + def _find_event_in_chunk(self, events: List[JsonDict]) -> JsonDict: + """ + Find the parent event in a chunk of events and assert that it has the proper bundled aggregations. + """ + for event in events: + if event["event_id"] == self.parent_id: + return event + + raise AssertionError(f"Event {self.parent_id} not found in chunk") + class RelationsTestCase(BaseRelationsTestCase): def test_send_relation(self) -> None: @@ -291,202 +301,6 @@ class RelationsTestCase(BaseRelationsTestCase): ) self.assertEqual(400, channel.code, channel.json_body) - @unittest.override_config({"experimental_features": {"msc3666_enabled": True}}) - def test_bundled_aggregations(self) -> None: - """ - Test that annotations, references, and threads get correctly bundled. - - Note that this doesn't test against /relations since only thread relations - get bundled via that API.
