[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] Compressing PB communication
by Tzahi Fadida June 30, 2006

June 30, 2006

I am interested in compressing the PB objects after serialization and unpacking when received at the other side. I a using the pb.PBClientFactory() and ServerFactory from the documentation. Where is the most proper place to hack this? What is possible? I need to do this after the object becomes a string so i won't have to pickle a string. Is it possible to do something like factory.protocol.serialize=mySerialize and in mySerialize i use the banana.encode function to encode the list of jelly … [View More]

[Twisted-Python] sAsync 0.1
by Ed Suominen June 30, 2006

June 30, 2006

Version 0.1 of sAsync, "SQLAlchemy Done Asynchronously" has been released at http://foss.eepatents.com/sAsync. It provides a Twisted-compatible way to use SQLAlchemy. There are now some usage examples at http://foss.eepatents.com/sAsync/wiki/Examples thanks to some people who are apparently already using the package. "sAsync offers asynchronous access to the outstanding SQLAlchemy package by Michael Bayer. It is built around an 'access broker' object that provides a priority-queued … [View More]

[Twisted-Python] LineOnlyReceiver does not notice when connection's failing
by Christian Schneider June 30, 2006

June 30, 2006

Hi all, I've got a twisted application that uses a LineOnlyReceiver as its protocol. All connections between clients and my server are open ended so I have to be sure they are working correctly. However, when I disrupt the network connection between a client and the server, the server happily keeps writing to the connection while the client closes its part and re-connects again. I am using sendLine to send the data but have also tried transport.write and transport.writeSomeData … [View More]

[Twisted-Python] Twisted-friendly Message bus
by Phil Mayers June 30, 2006

June 30, 2006

All, I've run into "this service needs to know about this event from this other service" once too often. It's message bus time, baby. However, many of the daemons I use are locally-written Twisted code, so a Twisted-friendly (async api) one would be nice. Note also that other non-Twisted code will need to connect to it, so rolling my own (aside from it being a bad idea from a NIH perspective) is out. I could of course wrap the message queue receiver for something well-proven like Spread … [View More]
