Hello everyone,
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):
def _ebGotServers(self, failure):
failure.trap(DNSNameError)
# Some DNS servers reply with NXDOMAIN when in fact
there are
# just no SRV records for that domain. Act as if we just
got an
# empty response and use fallback.
self.servers = []
self.orderedServers = []
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.
Thank you,
Gabriel
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...
It may be better to show a log of what is happening.
It should show something like the following :

This will keep trying until you quit. You can set a limit on how many
times it retries.
Best regards,
Gabriel

Ok, I finally created a class that wraps the client.XMPPClientFactory
function and calls callbacks when the connection fails. Thanks
