[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

[Twisted-Python] 100% CPU on high opened descriptors
by Juan Antonio Ibañez Santorum 19 May '11

19 May '11

Hello! I have a Linux box serving my twisted app. All works ok except after some days running (where I can see my CPU going to 100%). I saw that CPU goes 100% usage when the app reaches to 1024 opened descriptors (sockets). It seems TM isn't closing some connections when clients loose connection to the server. I have no more than 200 simultaneous clients, each of then using a single connection. Any idea why those connections remain open? Regards

[Twisted-Python] Ubuntu package of Twisted 11.0 for Lucid
by Alexandre Quessy 01 May '11

01 May '11

Hello everyone, I just made a Ubuntu package of Twisted 11.0 or Ubuntu Lucid (10.04) and put in on a PPA: https://launchpad.net/~sat-metalab/+archive/metalab To install it, simply do this: sudo add-apt-repository ppa:sat-metalab/metalab sudo apt-get update sudo apt-get install python-twisted-core Once enough people tested it, someone could copy it to the official Twisted PPA. And then, we can build it for Ubuntu Maverick as well. There is only one doubt I have, that should be sorted out quite soon. We will keep this mailing list updated. Best regards, -- Alexandre Quessy http://alexandre.quessy.net/

[Twisted-Python] Did anyone use twisted on windows (IOCP)?
by Dfgqq Dfgqq 29 Apr '11

29 Apr '11

Hi All Currently, i am planning rewrite some parts with twisted & iocp. These parts are related to Tcp connection without SSL. I want to know whether IOCP is ready for production or not. I ran some tests with twisted 10.20, 8.10 before. The IOCP part had many problems. I haven't give a try with 11.0. What is the progress for windows support? Thanks gelin yan

[Twisted-Python] Question about StreamServerEndpointService
by Albert Brandl 28 Apr '11

28 Apr '11

Hi! I have a question regarding `t.a.i.StreamServerEndpointService`. This class maintains an attribute `_waitingForPort` that holds the deferred returned by the `listen` method of the endpoint. If this attribute is None, the method `privilegedStartService` is called by `startService`, triggering the endpoint's `listen` method (among other things). I don't understand why this attribute is not reset to `None` when `stopService` is executed. With the deferred still around, starting the service again doesn't seem to work as expected, since it will not call `privilegedStartService` the second time. I might be wrong, but this looks like a bug to me. Maybe I didn't understand how to use this class, though... Any comments?
