Hello everyone,<br>
<br>
I wrote an XMPP client and I have a question, when it tries to connect and the server is not listening, it doesn't send back an error and tries forever. I see that this function (twisted/names/srvconnect.py):<br>
<br>
def _ebGotServers(self, failure):<br>
failure.trap(DNSNameError)<br>
<br>
# Some DNS servers reply with NXDOMAIN when in fact there are<br>
# just no SRV records for that domain. Act as if we just got an<br>
# empty response and use fallback.<br>
<br>
self.servers = []<br>
self.orderedServers = []<br>
<br>
traps the exception so it never propagates to me, so I can't handle it. Any ideas? I using the XMPP client example as a base for my code.<br>
<br>
Thank you,<br>
Gabriel<br>

Ok, the code I showed has nothing to do with the problem I think, what I don't get is the client never returns an error if nobody's listening...<br>
