From 48a5c47a9f7379f3b7e85c5a8dcbae346eb22310 Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Thu, 1 Sep 2022 14:57:47 -0400 Subject: [PATCH] Add a schema delta to drop unstable private read receipts. (#13692) Otherwise they'll be leaked due to the filtering code only respecting the stable identifiers for private read receipts. --- changelog.d/13692.removal | 1 + ...5remove_unstable_private_read_receipts.sql | 19 +++++++++++++++++++ 2 files changed, 20 insertions(+) create mode 100644 changelog.d/13692.removal create mode 100644 synapse/storage/schema/main/delta/72/05remove_unstable_private_read_receipts.sql diff --git a/changelog.d/13692.removal b/changelog.d/13692.removal new file mode 100644 index 000000000..eb075d451 --- /dev/null +++ b/changelog.d/13692.removal @@ -0,0 +1 @@ +Remove support for unstable [private read receipts](https://github.com/matrix-org/matrix-spec-proposals/pull/2285). diff --git a/synapse/storage/schema/main/delta/72/05remove_unstable_private_read_receipts.sql b/synapse/storage/schema/main/delta/72/05remove_unstable_private_read_receipts.sql new file mode 100644 index 000000000..36b41049c --- /dev/null +++ b/synapse/storage/schema/main/delta/72/05remove_unstable_private_read_receipts.sql @@ -0,0 +1,19 @@ +/* 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. + */ + +-- Drop previously received private read receipts so they do not accidentally +-- get leaked to other users. +DELETE FROM receipts_linearized WHERE receipt_type = 'org.matrix.msc2285.read.private'; +DELETE FROM receipts_graph WHERE receipt_type = 'org.matrix.msc2285.read.private';
