From 807ec3bd99908d2991d2b3d0615b0862610c6dc3 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> Date: Wed, 6 Nov 2019 10:01:39 +0000 Subject: Fix bug which caused rejected events to be stored with the wrong room state (#6320) Fixes a bug where rejected events were persisted with the wrong state group. Also fixes an occasional internal-server-error when receiving events over federation which are rejected and (possibly because they are backwards-extremities) have no prev_group. Fixes #6289. --- tests/handlers/test_federation.py | 126 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 126 insertions(+) (limited to 'tests/handlers/test_federation.py') diff --git a/tests/handlers/test_federation.py b/tests/handlers/test_federation.py index d56220f403..b4d92cf732 100644 --- a/tests/handlers/test_federation.py +++ b/tests/handlers/test_federation.py @@ -12,13 +12,19 @@ #
