From 719488dda87b04e4650a32f0c2b0b71782e0d48b Mon Sep 17 00:00:00 2001 From: lukasdenk <63459921+lukasdenk@users.noreply.github.com> Date: Mon, 3 Oct 2022 14:30:45 +0100 Subject: [PATCH] Add query parameter `ts` to allow appservices set the `origin_server_ts` for state events. (#11866) MSC3316 declares that both /rooms/{roomId}/send and /rooms/{roomId}/state should accept a ts parameter for appservices. This change expands support to /state and adds tests. --- changelog.d/11866.feature | 1 + synapse/handlers/room_member.py | 13 ++++ synapse/rest/client/room.py | 34 +++++---- tests/rest/client/test_rooms.py | 119 +++++++++++++++++++++++++++++++- 4 files changed, 152 insertions(+), 15 deletions(-) create mode 100644 changelog.d/11866.feature diff --git a/changelog.d/11866.feature b/changelog.d/11866.feature new file mode 100644 index 000000000..0b52caf80 --- /dev/null +++ b/changelog.d/11866.feature @@ -0,0 +1 @@ +Allow application services to set the `origin_server_ts` of a state event by providing the query parameter `ts` in `PUT /_matrix/client/r0/rooms/{roomId}/state/{eventType}/{stateKey}`, per [MSC3316](https://github.com/matrix-org/matrix-doc/pull/3316).
