From 18074c3c234aa240b9ab780fe31ff4b650405e45 Mon Sep 17 00:00:00 2001 From: mathieui Date: Thu, 2 Aug 2012 01:09:10 +0200 Subject: Add simple communication blocking (Fixes #1837) - Add /block, /unblock, and /list_blocks commands - Enable the commands only if the server advertises the feature - http://xmpp.org/extensions/xep-0191.html#example-9 was not tested, but should work (could not find a server to test with) - Add documentation for the commands --- src/connection.py | 1 + src/tabs.py | 118 +++++++++++++++++++++++++++++++++++++++++++++++++++++- 2 files changed, 118 insertions(+), 1
