From 390b7ce946173b41a61f427ef25a9a1d0371ad0b Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Thu, 1 Sep 2022 12:52:03 -0400 Subject: [PATCH] Disable calculating unread counts unless the config flag is enabled. (#13694) This avoids doing work that will never be used (since the resulting unread counts will never be sent in a /sync response). The negative of doing this is that unread counts will be incorrect when the feature is initially enabled. --- changelog.d/13694.bugfix | 1 + synapse/config/experimental.py | 3 ++ synapse/push/bulk_push_rule_evaluator.py | 7 +++- tests/storage/test_event_push_actions.py | 42 +++++++++++------------- 4 files changed, 30 insertions(+), 23 deletions(-) create mode 100644 changelog.d/13694.bugfix diff --git a/changelog.d/13694.bugfix b/changelog.d/13694.bugfix new file mode 100644 index 0000000000..48b9bb5f0a --- /dev/null +++ b/changelog.d/13694.bugfix @@ -0,0 +1 @@ +Fix a bug introduced in Synapse v1.20.0 that would cause the unstable unread counts from [MSC2654](https://github.com/matrix-org/matrix-spec-proposals/pull/2654) to be calculated even if the feature is disabled. diff --git a/synapse/config/experimental.py b/synapse/config/experimental.py index 260db49cad..702b81e636 100644 --- a/synapse/config/experimental.py +++ b/synapse/config/experimental.py @@ -71,6 +71,9 @@ class ExperimentalConfig(Config): self.msc3720_enabled: bool = experimental.get("msc3720_enabled", False) # MSC2654: Unread counts + # + # Note that enabling this will result in an incorrect unread count for + # previously calculated push actions. self.msc2654_enabled: bool = experimental.get("msc2654_enabled", False) # MSC2815 (allow room moderators to view redacted event content) diff --git a/synapse/push/bulk_push_rule_evaluator.py b/synapse/push/bulk_push_rule_evaluator.py index ccd512be54..d1caf8a0f7 100644 --- a/synapse/push/bulk_push_rule_evaluator.py +++ b/synapse/push/bulk_push_rule_evaluator.py @@ -262,7 +262,12 @@ class BulkPushRuleEvaluator: # This can happen due to out of band memberships return - count_as_unread = _should_count_as_unread(event, context) + # Disable counting as unread unless the experimental configuration is + # enabled, as it can cause additional (unwanted) rows to be added to the + # event_push_actions table. + count_as_unread = False + if self.hs.config.experimental.msc2654_enabled: + count_as_unread = _should_count_as_unread(event, context) rules_by_user = await self._get_rules_for_event(event) actions_by_user: Dict[str, Collection[Union[Mapping, str]]] = {} diff --git a/tests/storage/test_event_push_actions.py b/tests/storage/test_event_push_actions.py index 62fd4aeb2f..fc43d7edd1 100644 --- a/tests/storage/test_event_push_actions.py +++ b/tests/storage/test_event_push_actions.py @@ -67,9 +67,7 @@ class EventPushActionsStoreTestCase(HomeserverTestCase): last_event_id: str - def _assert_counts( - noitf_count: int, unread_count: int, highlight_count: int - ) -> None: + def _assert_counts(noitf_count: int, highlight_count: int) -> None: counts = self.get_success( self.store.db_pool.runInteraction( "get-unread-counts", @@ -82,7 +80,7 @@ class EventPushActionsStoreTestCase(HomeserverTestCase): counts, NotifCounts( notify_count=noitf_count, - unread_count=unread_count, + unread_count=0, highlight_count=highlight_count, ), ) @@ -112,27 +110,27 @@ class EventPushActionsStoreTestCase(HomeserverTestCase): ) ) - _assert_counts(0, 0, 0) + _assert_counts(0, 0) _create_event() - _assert_counts(1, 1, 0) + _assert_counts(1, 0) _rotate() - _assert_counts(1, 1, 0) + _assert_counts(1, 0) event_id = _create_event() - _assert_counts(2, 2, 0) + _assert_counts(2, 0) _rotate() - _assert_counts(2, 2, 0) + _assert_counts(2, 0) _create_event() _mark_read(event_id) - _assert_counts(1, 1, 0) + _assert_counts(1, 0) _mark_read(last_event_id) - _assert_counts(0, 0, 0) + _assert_counts(0, 0) _create_event() _rotate() - _assert_counts(1, 1, 0) + _assert_counts(1, 0) # Delete old event push actions, this should not affect the (summarised) count. # @@ -151,35 +149,35 @@ class EventPushActionsStoreTestCase(HomeserverTestCase): ) ) self.assertEqual(result, []) - _assert_counts(1, 1, 0) + _assert_counts(1, 0) _mark_read(last_event_id) - _assert_counts(0, 0, 0) + _assert_counts(0, 0) event_id = _create_event(True) - _assert_counts(1, 1, 1) + _assert_counts(1, 1) _rotate() - _assert_counts(1, 1, 1) + _assert_counts(1, 1) # Check that adding another notification and rotating after highlight # works. _create_event() _rotate() - _assert_counts(2, 2, 1) + _assert_counts(2, 1) # Check that sending read receipts at different points results in the # right counts. _mark_read(event_id) - _assert_counts(1, 1, 0) + _assert_counts(1, 0) _mark_read(last_event_id) - _assert_counts(0, 0, 0) + _assert_counts(0, 0) _create_event(True) - _assert_counts(1, 1, 1) + _assert_counts(1, 1) _mark_read(last_event_id) - _assert_counts(0, 0, 0) + _assert_counts(0, 0) _rotate() - _assert_counts(0, 0, 0) + _assert_counts(0, 0) def test_find_first_stream_ordering_after_ts(self) -> None: def add_event(so: int, ts: int) -> None:
