hi there, folks:
I'd really like to release 0.7.0 but I would like it to be at least a
little bit tested before I do so. Could those of you with CVS trees check
everything out and see if it performs as advertised? Deeper bugs than
that will have to wait for the next release, but I'd at least like to know
if it works for someone other than me.

I would like to announce txZMQ, ZeroMQ bindings for Twisted. txZMQ is based
on pyzmq and requires recent ØMQ version (>=2.1).
txZMQ uses ØMQ APIs to get file descriptor that is used to signal pending
actions from ØMQ library IO thread running in separate thread. txZMQ should
be usable with any Twisted reactor.
* The socket library that acts as a concurrency framework.
* Carries messages across inproc, IPC, TCP, and multicast.
* Connect N-to-N via fanout, pubsub, pipeline, request-reply.
* Fast enough for clustered products and supercomputing.
* Asynch I/O for scalable multicore message-passing apps.
Bridging ØMQ and Twisted makes a nice match: fast simple messaging between
Twisted instances solving complex problems :)
* PyPi: http://pypi.python.org/pypi/txZMQ/
* Source code: https://github.com/smira/pyzmq
* pyzmq: http://pypi.python.org/pypi/pyzmq
* ØMQ: http://www.zeromq.org/

This solution didn't work because 'transport' isn't a property of the

SimpleXMLRPCServer to a twisted XMLRPC server solution and I need to
insert the client IP into the attributes passed to the called xmlrpc
method. Anyone who knows the answer and is willing to share the info?
My proposal for delivering a 4h Twisted training in EuroPython 2012 (Florence, July 2-8) has been voted in the community and is set to be delivered on July 5. https://ep2012.europython.eu/conference/talks/twisted-tutorial This turned out to be very popular last year, and had to be repeated on a second day to cover all the audience.
Unfortunately for personal reasons I won't be able to attend the conference. Before I give back the slot to the EuroPython organizers, I wonder if someone that would be attending would want to deliver the training in my place. I have a lot of material already from last year, and I can happily work for the preparation of the training.
I need to give an answer to the organizers in the next few days, so if someone's interested, please speak up!
Dear all ...
I need my twistd script to also 'listen' to dbus.
The only example that I found so far is :
Buit that example not using some thing like :
application = service.Application("MyApp")
Is there any example of dbus implementation on twistd that use
I have a ticket open for allowing tests that look like this, where each
run has a new reactor instance:
def test_somethingShouldHappen(self, reactor):
result = 
Further thought suggests however that this doesn't add much,
necessarily, over the current "return a Deferred" idiom for most users.
Experience with ReactorBuilder framework that has similar testing
mechanism suggests it's far too easy to fail to stop the reactor.
Moreover, things like coiterate() don't work since they rely on
pre-imported global reactor, and given the "from twisted.internet import
reactor" idiom this testing style won't work well for many people's code.
But! ReactorBuilder tests are superior in one way: no
DirtyReactorWarning. You don't have to wait until all connections are
closed, which is difficult, or make sure to cancel every timeout. This
makes test writing simpler.
Perhaps we should get rid of DirtyReactorWarning for regular
Deferred-returning tests as well, then. We have all the infrastructure
we need, after all, for canceling scheduled events and disconnecting all
descriptors. We might want to log when we do so, to help debug things,
but we already have cleanup code mostly implemented in trial anyway, and
it seems like DirtyReactorWarning doesn't usually make future tests fail
anyway since we do run cleanup.
Threaded code might still be a problem, but that's the case for current
tests now, and even switching to a new style of tests as above would
only somewhat mitigate the issue.
I'm trying to connect to homematic server at address '192.168.1.251'
and port '2001'. I have a sample twisted server and client on my localhost.
It's working fine. Now to the functions in server protocol.py file, I added
another function (as shown below) which creates another client that
connects to homematic server. But it's giving following error when I start
line 45, in xmlrpc_init
d = ClientCreator(reactor).connectTCP(self,'192.168.1.251',2001)
exceptions.TypeError: __init__() takes at least 3 arguments (2
my scenario is this way:
mycleint ---> myserver(protocol file--->cliet-->homematic server)
Please help me out.

Are you sure you need to do this? The behavior is already to go back
from "from" after "data" (by way of a RSET command).

The method referred to by the attribute `_failresponse` is called if the
server responds with an unexpected code. Set that to a different
handler, to handle failures from the server differently.
