From 9453c65948bce69f259c1ba1005565d86b1d8730 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Tue, 25 Sep 2018 17:38:54 +0100 Subject: remove spurious federation checks on localhost There's really no point in checking for destinations called "localhost" because there is nothing stopping people creating other DNS entries which point to 127.0.0.1. The right fix for this is https://github.com/matrix-org/synapse/issues/3953. Blocking localhost, on the other hand, means that you get a surprise when trying to connect a test server on localhost to an existing server (with a 'normal' server_name). --- synapse/federation/transaction_queue.py | 37 ++++++--------------------------- 1 file changed, 6 insertions(+), 31 deletions(-) diff --git a/synapse/federation/transaction_queue.py b/synapse/federation/transaction_queue.py index 8cbf8c4f7f..ae47aaae0b 100644 --- a/synapse/federation/transaction_queue.py +++ b/synapse/federation/transaction_queue.py @@ -137,26 +137,6 @@ class TransactionQueue(object): self._processing_pending_presence = False - def can_send_to(self, destination): - """Can we send messages to the given server? - - We can't send messages to ourselves.
