[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz Aug. 5, 2021

Aug. 5, 2021

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. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |… [View More]

[Twisted-Python] Problem: spawnProcess() never ending when installSignalHandlers=False
by Matt Feifarek Feb. 3, 2007

Feb. 3, 2007

Hello. I'm using Twisted 1.3.0 on python2.4 on an Ubuntu-Hoary x86 Linux box. I'm using twisted and spawnProcess() with a Queue structure to chain processes that need to be called (specifically, imagemagick commands). I use the "processEnded" event/method of t.i.p.ProcessProtocol to go from one task to the next. Twisted shares a python process with a multi-threaded web-app-kit (Webware) so it has to be run in a thread. This worked well on other older versions of twisted and older versions of … [View More]

[Twisted-Python] Service dependencies
by Matt Goodall July 10, 2006

July 10, 2006

Hi, I have a couple of services. The second is dependent on the first being fully initialised before the second gets set up. I thought that the order of Service startup was typically handled by organising services in a hierarchy, and that the startup of the hierarchy understood deferreds. I was wrong - service.Application is a MultiService and only understands deferreds in stopService. There's a DependentMultiService class in twisted.internet.app but that entire module has been deprecated. … [View More]

[Twisted-Python] Status of wxPython support in Twisted 2.1: use wxreactor
by Itamar Shtull-Trauring July 1, 2006

July 1, 2006

wxreactor in Twisted 2.1 uses threadedselectreactor. This means that wx apps ought to use wxreactor, not TSR directly; there are some issues with vanilla TSR wx integration that are also present in wxreactor, but will be fixed in future versions of wxreactor. What's broken (there may be more): 1. reactor shutdown events aren't handled correctly (e.g. Deferred returned from during-shutdown event). 2. Signal handling for e.g. Ctrl-C is caught by wx, not twisted. In order to get these fixed I … [View More]

[Twisted-Python] Deferred ownership and the Protocols
by Andy Leszczynski Jan. 31, 2006

Jan. 31, 2006

Hi, I am in the process of designing the custom Protocol and will use Deferred-s in order to pass the asynchronous results. I try to learn from the current Twisted code base. For instance there are two modules smtp.py and web/client.py: def getPage(url, contextFactory=None, *args, **kwargs): [] factory = HTTPClientFactory(url, *args, **kwargs) [] reactor.connectTCP(host, port, factory) [] return factory.deferred def sendEmail(smtphost, fromEmail, toEmail, content, … [View More]

[Twisted-Python] How to do cleanup to server on sigint
by Rob Mason Jan. 31, 2006

Jan. 31, 2006

Hi , I am using twisted to write a test client to interface with a server running a bespoke protocol. The server expects interactions from the client something like: attach sendMessage sendMessage . . . unattach If the server does not receive a specific unattach from the client , it will maintain a resource open for the client even though there is no connection. Eventually the server will refuse additional connections (once it's number of '… [View More]

[Twisted-Python] Re: parallel callbacks? Or inserting into the callback chain?
by Lenny G Arbage Jan. 28, 2006

Jan. 28, 2006

Okay, I think I figured it out. The idea is to create new Deferreds for each call, but keep the 'matching' ones in a list. Then, when the first fires, use it to fire callbacks for each of those: from twisted.internet import reactor, defer pending = {} waiting = {} def getDummyData(queryName, x): def serviceWaiting(res, x): #print "in saveResult" if waiting.has_key(x): #print "waiting has_key" for i in waiting[x]: #print "calling … [View More]
