[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing

by Glyph Lefkowitz

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

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] How do I write AMP Command definitions TTD-edly?

by Laurens Van Houtven

Hi, I have no issue writing AMP responders TTD-edly, they work pretty much the way any other code would. However, I did notice that the only way I'd notice if my Command definitions themselves were broken were if my functional tests start failing. It would be nice if I could write unit test driven Command specifications, as well. The quickest I could come up with was to call makeArguments/makeResponse with a few known-good/known-bad dictionaries, and see if it blows up. Is there a smarter way to do it? -- cheers lvh

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

by Remy C. Cool

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] Twisted source, changes and social analysis

by Jonathan Stoppani

Hello everybody (with access to the Trac DB), I am currently doing my master thesis on the "analysis and management of change propagation in complex systems". I'm concentrating my efforts on software-based complex systems. As part of my analysis, I gather data from different domains, such as dependencies between modules of the source code, interactions between people (like, for example, this mailing list) and change requests (in this specific case, issues and tickets on an issue tracking system). A couple of weeks ago I asked on IRC if it would be possible to get the Trac data from twistedmatrix.com and I was told to write a script to dump the database by excluding sensitive information. The script is up for review and auditing over here: https://gist.github.com/GaretJax/5264941 It can be run by saving it to a .py file or directly with the following command: curl -s https://gist.github.com/GaretJax/5264941/raw/c478c2c4ec39cdb4bc3ceeb05d57a3… | python - <projenv> <outfile> (by replacing the two arguments: trac base directory and the output file). There are no privacy concerns, as all data being analyzes is publicly available, either in the repository, in the mailing list archives or on twistedmatrix.com After being reviewed, can someone with access to the server please run it for me? Thanks, Jonathan P.S.: If someone would like more details about the research, a draft of the project statement can be found here: https://www.dropbox.com/s/qu3jpxcd4wpat2i/statement-0-r0-2013-03-19.pdf

[Twisted-Python] Reason of calling Stale Broker inside loopback

by Sergey Gerasimov

Hello, 1. What is the reason of error "DeadReferenceError: Calling Stale Broker"? My program uses PB inside loopback, so I shouldn't have any disconnects. 2. I call many time remote method returning pb.Referenceable. Can it be a reason of topic 1 or generally lead to system's degradation? Sergey.
