From 76dbd7b8d62beb10ee9304000fad62f65ba23876 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> Date: Tue, 7 Jul 2020 14:20:40 +0100 Subject: [PATCH] Stop populating unused table `local_invites`. (#7793) This table is no longer used, so we may as well stop populating it. Removing it would prevent people rolling back to older releases of Synapse, so that can happen in a future release. --- changelog.d/7793.misc | 1 + synapse/storage/data_stores/main/events.py | 98 +++++-------------- .../storage/data_stores/main/events_worker.py | 5 +- .../storage/data_stores/main/purge_events.py | 1 - tests/rest/admin/test_room.py | 1 - 5 files changed, 25 insertions(+), 81 deletions(-) create mode 100644 changelog.d/7793.misc diff --git a/changelog.d/7793.misc b/changelog.d/7793.misc new file mode 100644 index 000000000..2b6cfbe27 --- /dev/null +++ b/changelog.d/7793.misc @@ -0,0 +1 @@ +Stop populating unused table `local_invites`. diff --git a/synapse/storage/data_stores/main/events.py b/synapse/storage/data_stores/main/events.py index b7bf3fbd9..a18317366 100644 --- a/synapse/storage/data_stores/main/events.py +++ b/synapse/storage/data_stores/main/events.py @@ -27,12 +27,7 @@ from prometheus_client import Counter from twisted.internet import defer import synapse.metrics -from synapse.api.constants import ( - EventContentFields, - EventTypes, - Membership, - RelationTypes, -) +from synapse.api.constants import EventContentFields, EventTypes, RelationTypes from synapse.api.room_versions import RoomVersions from synapse.crypto.event_signing import compute_event_reference_hash from synapse.events import EventBase # noqa: F401 @@ -819,7 +814,6 @@ class PersistEventsStore: "event_reference_hashes", "event_search", "event_to_state_groups", - "local_invites", "state_events", "rejections", "redactions", @@ -1196,65 +1190,27 @@ class PersistEventsStore: (event.state_key,), ) - # We update the local_invites table only if the event is "current", - # i.e., its something that has just happened.
