Description Alban Crequy 2008-02-13 10:01:08 UTC 
When I join a MUC channel, I get the last few messages sent by people when I was not there because theses messages are stored by the MUC server, so that it can send them to me.

According to http://telepathy.freedesktop.org/xmpp/muc-bytestream.html D-Bus messages are encapsuled in a <message/> stanza. So they are also saved by the server.

I use telepathy-python/examples/tube-dbus-muc.py to test this:
1. launch the initiator
2. wait until a few signals "Hello" are emitted
3. launch the client
4. the client receives all signals emitted before the client join the chatroom.

So the client receives D-Bus messages from the past.

It sounds undesirable. On the client, Gabble should drop messages containing D-Bus messages if they are sent before the client join the chatroom.

Isn't the goal of these markups to avoid that?

<amp xmlns='http://jabber.org/protocol/amp'>
    <rule condition='deliver' value='stored' action='error'/>
    <rule condition='match-resource' value='exact' action='error'/>
</amp>

I don't know whether these markups (XEP-0079) can be used on MUC, but they seem to be not implemented on current Jabber servers, see http://bugs.freedesktop.org/show_bug.cgi?id=14485#c2
