[Twisted-Python] Replacement for Twisted Tutorial in Europython 2012
by Orestis Markou 09 Jun '12

09 Jun '12

Hello everyone, 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! Thanks, Orestis

[Twisted-Python] protocol connectionLost clientConnectionLost
by Kevin McIntyre 07 Jun '12

07 Jun '12

Below is my sample code. I'm hoping to unplug my internet cable and get a connectionLost. But this doesn't happen. Is there anyway to detect this? ------ from twisted.internet.protocol import Protocol, ReconnectingClientFactory from twisted.internet import reactor class Echo(Protocol): def connectionMade(self): print "cool and the gang" def connectionLost(self, reason): print "ut-oh %s" % reason def dataReceived(self, data): pass class EchoClientFactory(ReconnectingClientFactory): def startedConnecting(self, connector): print 'Started to connect.' def buildProtocol(self, addr): print 'Connected.' print 'Resetting reconnection delay' self.resetDelay() return Echo() def clientConnectionLost(self, connector, reason): print 'Lost connection. Reason:', reason ReconnectingClientFactory.clientConnectionLost(self, connector, reason) def clientConnectionFailed(self, connector, reason): print 'Connection failed. Reason:', reason ReconnectingClientFactory.clientConnectionFailed(self, connector, reason) if ( __name__ == "__main__" ): reactor.connectTCP("74.125.224.242", 80, EchoClientFactory() ) #connect to google on port 80 reactor.run() -- Kevin McIntyre | Software Engineer | Green Charge Networks Cell 718-249-5058 | kmcintyre(a)greenchargenet.com | www.greenchargenet.com

I recently upgraded to 12.0.0 and was running my process in the shell, when this error/warning was thrown. Any idea what it means?

by Thomas Hervé 05 Jun '12

05 Jun '12

On behalf of Twisted Matrix Laboratories, I am pleased to announce the release of Twisted 12.1. 107 tickets are closed by this release, with the following highlights: * 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. This is the last Twisted release supporting Python 2.5. For more information, see the NEWS file here: http://twistedmatrix.com/Releases/Twisted/12.1/NEWS.txt Download it now from: http://pypi.python.org/packages/source/T/Twisted/Twisted-12.1.0.tar.bz2 or http://pypi.python.org/packages/2.5/T/Twisted/Twisted-12.1.0.win32-py2.5.msi or http://pypi.python.org/packages/2.6/T/Twisted/Twisted-12.1.0.win32-py2.6.msi or http://pypi.python.org/packages/2.7/T/Twisted/Twisted-12.1.0.win32-py2.7.msi Thanks to the supporters of Twisted via the Software Freedom Conservancy and to the many contributors for this release. -- Thomas
