You can find the tarballs to test here: http://people.canonical.com/~therve/Twisted/12.1.0pre1/ Among the 106 tickets closed during that timeframe, you can find: * The revival of the kqueue reactor for BSD platforms. * epoll is now the default reactor under Linux after a fix to handle files on stdin/stdout. * New reactors supporting GTK3 and GObject-Introspection. * Several enhancements regarding file descriptors passing: systemd support for servers, ability to send and receive file descriptors for IReactorUNIX and an AMP argument using that feature. * Support for IPv6 literals in connectTCP. * Persistent connections support for the new HTTP client. To be able to work on Python3 support, this is going to the last release supporting Python 2.5. Please give it a round of tests to help make a great release! Thanks, </pre> Thomas Hervé 2012-05-26T16:30:05 http://comments.gmane.org/gmane.comp.python.twisted/24312 <pre>Greetings! First of all we would like to thank you for your interest in our proposal.

Been trying to modify twisted.mail.smtp.ESMTPClient to allow the sending of more than one message over a single TCP connection. I've changed the behavior of smtpState_data() so that it sets the next state to smtpState_from if there is another message to send, and this seems to work unless there's an error returned by the server. In this case the connection is still closed on the client side after smtpState_msgSent, and I need to suppress this. The subsequent message should still be sent on the open TCP connection error or not, according to my needs, however I'm having a heck of time tracking down where the disconnection is occurring. My current code (with debugging statements) is here: https://gist.github.com/2777154 Any help is greatly appreciated. This client is being used to run functional tests. -J </pre> Jason J. W.

I have a second piece of software, which is both a client regarding the core server, and a web server. At last, the web client is the web browser of your choice. The web server is a Django application, which means that (as far as I know) I cannot (easily) make it use asynchronous calls. At last, for the communication between the core server and the web server (which is, from this point of vue, a client), I was looking for something that let me use remote objects as if they were local. That is when I discovered Twisted. Twisted seems to be the kind of tool I want to use because it seems to be powerful, can use SSL, authentication, transm</pre> Louis 2012-05-16T22:58:57 http://comments.gmane.org/gmane.comp.python.twisted/24289 <pre>Hi, I'm writing a service that exposes a bunch of methods over AMP. These methods are easily logically grouped into separate modules (i.e. message-related, picture-related…). So, I'd like to define the behavior for those methods in those modules. However, the amp.Command.responder decorator only works inside the class definition of an AMP subclass. (http://twistedmatrix.com/documents/current/api/twisted.protocols.amp.Command.html#responder). Does that mean I should have multiple AMP subclasses? How do I get all of them to listen on the same port? Is this what the mysterious "routes" feature I've been hearing about does? Right now I'm doing it like this, which works but isn't very pretty or nice: user.py: ----- class Register(amp.Command): arguments = […] response = […] errors = […] def register(self, …): # do actual registering behavior here ----- api.py: ----- from project import auth class API(amp.AMP): register = auth.Register.responder(auth.register) ----- cheer</pre> Laurens Van Houtven 2012-05-16T14:26:00 http://comments.gmane.org/gmane.comp.python.twisted/24288 <pre>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 = [] reactor.listenTCP(...) self.runReactor(reactor) self.assertEqual(result, ["hooray"]) 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 DirtyRe</pre> Itamar Turner-Trauring 2012-05-15T10:26:24 http://comments.gmane.org/gmane.comp.python.twisted/24283 <pre>Hi, We're having some troubles today, because it seems that old packages of Twisted are not available anymore.

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!

Support contracts might include things like: A certified version of Twisted for your platform Twisted bug fixes Twisted feature development Answers to questions about Twisted functionality Answers to questions about Twisted best practices and design patterns Answers to questions about performance and scaling In-depth support for your specific applications Additional documentation Training Code review If you or your organization might be interested in such a thing, we'd appreciate your answering a quick questionnaire: http://bit.ly/JxrIbu Thanks, Jean-Paul </pre> exarkun< at >twistedmatrix.com 2012-05-04T19:43:57 http://comments.gmane.org/gmane.comp.python.twisted/24269 <pre> &gt; &gt; If anyone had a similar issue before, I'd appreciate any pointers on &gt; &gt; resolving or avoiding it. &gt; &gt; &gt; Actually, one thing does occur to me - are you using the IOCP reactor? &gt; If so, try the select() reactor, the IOCP reactor unfortunately has a &gt; bunch of serious bugs.

The old service used PERL for threading (very painful), so a while ago I changed everything to python using the twisted framework. the service's job is to launch a choose a firefox profile, launch the process and handle closes and crashes approprietly. the launch of version 2.5 is next week but I sure could use some feedback on the service code before releasing it. Keep in mind I haven't finishing commenting for public release. here are the files for the new service: 1) fireshark.py http://pastebin.mozilla.org/1614427 this is the main service. opens up a port to listen on, and uses the following two classes to manage profiles and launch a firefox process. 2) firesharkprofilemanager.py http://pastebin.mozilla.org/1614428 this is the firefox profile manager, it manages what firefox p</pre> Stephan 2012-05-03T15:56:36 http://comments.gmane.org/gmane.comp.python.twisted/24259 <pre>Hi All, Our team is setting up Twisted to access Mercurial over SSH. SSH connection, key exchange, and receiving large amount of data from the client work nicely, but sending server data back to the client ends up with a PuTTY Fatal Error "Incoming packet was garbled on decryption" at a random point. If plink compression is disabled, the error happens very rarely, but overall SSH performance becomes unacceptable. If plink uses compression, the error occurs within 1-10 seconds from starting data download. To make things more hectic, on a rare occasion, PuTTY reports "Incorrect MAC received on packet" instead of "garbled on decryption". If anyone had a similar issue before, I'd appreciate any pointers on resolving or avoiding it.

This will make life easier for one of our Google Summer of Code students who will be working on the start of Python 3 support, so it'd be good to get it done soon. In order to release 12.1, we need: 1. To finish code reviews of remaining 12.1 tickets and merge: http://twistedmatrix.com/trac/query?status=assigned&amp;status=new&amp;status=reopened&amp;group=status&amp;milestone=Twisted-12.1 These include two gtk3 tickets: gtk3 is new in 12.1, and I'd like to ship it bug free and feature complete. There's also a couple of tickets which will make epoll the default reactor on Linux. While not strictly necessary, they should be easy enough to get merged and it's a great feature to have in; if they become a bottleneck we can drop this and wait until the next release. 2. A volunteer to do the release.
