From 01d0f8e701b4c2ddd04eee1a26edef952c0ac558 Mon Sep 17 00:00:00 2001 From: Brendan Abolivier Date: Fri, 28 Jun 2019 15:17:15 +0100 Subject: [PATCH] Don't update the ratelimiter before sending a 3PID invite This would cause emails being sent, but Synapse responding with a 429 when creating the event. The client would then retry, and with bad timing the same scenario would happen again. Some testing I did ended up sending me 10 emails for one single invite because of this. --- synapse/handlers/room_member.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/synapse/handlers/room_member.py b/synapse/handlers/room_member.py index 4d6e883802..c860acf970 100644 --- a/synapse/handlers/room_member.py +++ b/synapse/handlers/room_member.py @@ -676,7 +676,7 @@ class RoomMemberHandler(object): # We need to rate limit *before* we send out any 3PID invites, so we # can't just rely on the standard ratelimiting of events. - yield self.base_handler.ratelimit(requester) + yield self.base_handler.ratelimit(requester, update=False) can_invite = yield self.third_party_event_rules.check_threepid_can_be_invited( medium, address, room_id
