From 4b17a5ace846d82b09fccce79da77a8207a6765f Mon Sep 17 00:00:00 2001 From: Erik Johnston Date: Wed, 28 Sep 2022 14:42:43 +0100 Subject: Handle remote device list updates during partial join (#13913) c.f. #12993 (comment), point 3 This stores all device list updates that we receive while partial joins are ongoing, and processes them once we have the full state. Note: We don't actually process the device lists in the same ways as if we weren't partially joined. Instead of updating the device list remote cache, we simply notify local users that a change in the remote user's devices has happened. I think this is safe as if the local user requests the keys for the remote user and we don't have them we'll simply fetch them as normal. --- .../delta/73/04pending_device_list_updates.sql | 28 ++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 synapse/storage/schema/main/delta/73/04pending_device_list_updates.sql (limited to 'synapse/storage/schema') diff --git a/synapse/storage/schema/main/delta/73/04pending_device_list_updates.sql b/synapse/storage/schema/main/delta/73/04pending_device_list_updates.sql new file mode 100644 index 0000000000..dbd78d677d --- /dev/null +++ b/synapse/storage/schema/main/delta/73/04pending_device_list_updates.sql @@ -0,0 +1,28 @@ +/* Copyright 2022 The Matrix.org Foundation C.I.C + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +-- Stores remote device lists we have received for remote users while a partial +-- join is in progress. +-- +-- This allows us to replay any device list updates if it turns out the remote +-- user was in the partially joined room +CREATE TABLE device_lists_remote_pending( + stream_id BIGINT PRIMARY KEY, + user_id TEXT NOT NULL, + device_id TEXT NOT NULL +); + +-- We only keep the most recent update for a given user/device pair. +CREATE UNIQUE INDEX device_lists_remote_pending_user_device_id ON device_lists_remote_pending(user_id, device_id); -- cgit 1.5.1
