[Twisted-Python] twistd -noy unable to cancel using CTRL+C when using threads
by Clark C. Evans Nov. 16, 2005

Nov. 16, 2005

Hello. The attached example works properly when called from twistd -nox test.py when one is not using threads. However, as soon as thread are introduced, you can no longer use CTRL+C to kill the process. I'm running FreeBSD 5.3-RELEASE and Python 2.4.1 Best, Clark

[Twisted-Python] Traceback bug?

This looks like a problem of Twisted's Failure: tb = a.getTraceback() File "C:\PROGRA~1\Python\Lib\SITE-P~1\twisted\python\failure.py", line 312, in getTraceback self.printTraceback(file=io, elideFrameworkCode=elideFrameworkCode, detail=detail) exceptions.TypeError: printTraceback() got an unexpected keyword argument 'detail' Should I file a bug, or is it my fault?

[Twisted-Python] How to talk to IM's
by Max Slimmer Nov. 14, 2005

Nov. 14, 2005

I am trying to get into twisted, I have gone through the examples and have purchased and read most of the book, but am still having problems understanding just how things hang together. Any pointers to other sample code, or documentation would be great. What I am trying to do is to use the WORDS modules and be able to connect to various IM servers and through them to known IM users. I have gotten the oscardemo to work connecting to ICQ, if I log in as user who is on another users buddy list … [View More]

>>This is a bug, not a feature. > > Why is it a bug? I've been bitten by this behavior.. basically it means that the TestCase's __init__ method is not invoked for each test method, so you have to remember to clear status flags (say, things that are set from a Deferred callback, like maybe a .oopsSomethingFailed flag) in setUp() rather than just initialize them in __init__ . The annoying thing is that it (the __init__ approach) works fine when you run the tests one at a time, which … [View More]

Yes, but with the standard Python build on Windows, you can only go up to 2000. So now, I can do 570 objects. I'm working on trying to track down editbin.exe so I can raise the stack size on python.exe and see how much farther I can go. > Stackless has nothing to do with this.

My object graph is a natural and clean data structure. I don't want to lose that just because of limitations in my tools. Is this currently being addressed or in a road map?
