[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz 05 Aug '21

05 Aug '21

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. Thanks. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |_____| |_____ | | | | @ t w i s t e d m a t r i x . c o m http://www.twistedmatrix.com/~glyph/

[Twisted-Python] [ANN] txZMQ released
by Andrey Smirnov 21 Jul '14

21 Jul '14

Hi! 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. ØMQ is: * 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 :) Links: * 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/ -- Andrey Smirnov, Qik Web Team Lead

[Twisted-Python] Get IP of connecting client in XMLRPC server

Hello, On 18 May 2004, the following message was posted to this mailinglist: Jp Calderone exarkun at divmod.com wrote: >Daniel Newton wrote: > > I have a simple XML-PRC server similar to the example below: > > from twisted.web import xmlrpc, server > > class Example(xmlrpc.XMLRPC): > """An example object to be published.""" > > def xmlrpc_add(self, a, b): > """Return sum of arguments.""" > return a + b def xmlrpc_whatIsMyAddress(self): return self.transport.getPeer().host > > if __name__ == '__main__': > from twisted.internet import reactor > r = Example() > reactor.listenTCP(7080, server.Site(r)) > reactor.run() > > I want to be able to get the address of the client that calls the xmlrpc > method can anyone help me with this? This solution didn't work because 'transport' isn't a property of the Example class. I'm currently in the process of changing from a customized 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? Regards, Remy

by Laurens Van Houtven 31 Jan '12

31 Jan '12

Hey! So, I volunteered to manage the sprint at PyCon 2012. Since no-one else has, I'm moving forward assuming I got the job ;-) You should sign up (which involves logging in on the PyCon site, scrolling to the bottom, clicking "Edit" and adding your name) to the sprint. This makes it easier for organizers to know how many people to expect where. Here's the signup link: https://us.pycon.org/2012/community/sprints/projects/ cheers lvh

[Twisted-Python] Problem passing objects with perspective broker
by Fourat ZOUARI 30 Jan '12

30 Jan '12

Hi, Whenever i try to pass an object (aClass) with a property with a second object (bClass) Am getting: *Unpersistable('Unpersistable data: instance of class amodule.bClass deemed insecure')* The aClass is copyable and unjellied, the bClass is not. Here's my code: server.py: from twisted.application import internet, service from twisted.spread import pb from amodule import PBServer application = service.Application("Test app") # Prepare managers clientManager = internet.TCPServer(8282, pb.PBServerFactory(PBServer())); clientManager.setServiceParent(application) if __name__ == '__main__': print "Run with twistd" import sys sys.exit(1) amodule.py: from twisted.spread import pb class bClass: """This is not a Copyable class """ class aClass(pb.RemoteCopy, pb.Copyable): b = bClass() pb.setUnjellyableForClass(aClass, aClass) class PBServer(pb.Root): def remote_echo(self, a): return a.b Is there anyway to unjelly aClass and all the objects it can contain ? because unjellying included object is a headache and may turn into dirty code ... Regards, Fourat

[Twisted-Python] IRCClient method naming advice
by Matthew Pounsett 28 Jan '12

28 Jan '12

I've found that the IRCClient protocol doesn't deal well with having its connection interrupted. If the TCP session goes away due to timeout or some other interruption, it doesn't appear to notice. As a result, I'm looking at adding appropriate methods to allow a client to initiate its own pings to the server so that it can detect when the connection is lost. I'll submit all this back via Trac when I can get in there. This will need IRCClient.irc_PONG(), which looks fairly straightforward to write, and the obvious method for the outgoing ping would be IRCClient.ping(), but that seems to have been taken up for DCC PING instead. Presumably it would upset people if backward compatibility was broken and that was changed to IRCClient.dccPing() to match the rest of the outgoing DCC methods. Does anyone have any opinion on what other method name would make sense and still be close to maintaining consistency with the rest of the outgoing method names?
