Does twisted have a python3 story? Whatever it is, it should probably be in the release 10 doc and perhaps also on the web site. --rich

[Twisted-Python] autoincrement in axiom
by code prophecy 01 Mar '10

01 Mar '10

Hi, Is there a way to use autoincrement in axiom ? I need a property in my model that reflects the last row id after every insert operation. Also, is it safe to use non-db variables in axiom model ? something like class test1(Item): name = attributes.text() surname = "my non db variable" The interpretor does throw an error but that can be overcome by using self.__dict__['surname'] = "non db" . Just wanted to know if this is recommended or not sorry, if this' already been answered; i did search but couldn't find the answer. Thanks

[Twisted-Python] Getting factory with AuthenticatingTelnetProtocol
by Skye 28 Feb '10

28 Feb '10

Hello, I used the code from this thread to figure out how to use the twisted.conch.telnet.AuthenticatingTelnetProtocol class: http://www.mail-archive.com/twisted-python@twistedmatrix.com/msg01581.html (with the addition of av.state = 'Command' in requestAvatar(), it works great) However, after the handoff to the new protocol MyTelnet, self.factory isn't set. How can I pass along the parent factory from the AuthenticatingTelnetProtocol instance to the StatefulTelnetProtocol instance? Sorry if this isn't phrased correctly - I'm new to Twisted. Thanks, Skye

[Twisted-Python] double slash '//' problem in url - authentication with guard.HTTPAuthSessionWrapper
by Ravikant Patil 26 Feb '10

26 Feb '10

Hi, I am trying to understand how basic authentication can be used with twisted.web. twistedmatrix provides an example on the same which is reproduced at >> *http://pastebin.com/hE5TFpZT * when I use this example code to login, it works fine but returns with double slash '//' in url before index file or rather for any file accessed. like: >> http://localhost:8889//index.html it will work for all files with double slash >> http://localhost:8889//vision.html but will return index page for any request with single slash >> http://localhost:8889/anything.html/ will always return index page. Please help me figuring out what is the problem and what can be possible fix to it. Thank you. Regards, Ravikant.

[Twisted-Python] Another newbie question... out of file descriptors?
by K. Richard Pixley 26 Feb '10

26 Feb '10

Can anyone explain this result to me? It looks to me as though the SelectReactor is leaking file descriptors. Granted, it's a pathological case, but it's not uncommon if you're running a bunch of tests. --rich rich(a)black.noir.com> cat demo.py from twisted.internet.selectreactor import SelectReactor for i in xrange(1024): SelectReactor() rich(a)black.noir.com> python demo.py Traceback (most recent call last): File "demo.py", line 4, in <module> SelectReactor() File "/home/rich/projects/sprained/sprained-dev/lib/python2.6/site-packages/Twisted-9.0.0_r28543-py2.6-linux-x86_64.egg/twisted/internet/selectreactor.py", line 72, in __init__ posixbase.PosixReactorBase.__init__(self) File "/home/rich/projects/sprained/sprained-dev/lib/python2.6/site-packages/Twisted-9.0.0_r28543-py2.6-linux-x86_64.egg/twisted/internet/base.py", line 471, in __init__ self.installWaker() File "/home/rich/projects/sprained/sprained-dev/lib/python2.6/site-packages/Twisted-9.0.0_r28543-py2.6-linux-x86_64.egg/twisted/internet/posixbase.py", line 266, in installWaker self.waker = _Waker(self) File "/home/rich/projects/sprained/sprained-dev/lib/python2.6/site-packages/Twisted-9.0.0_r28543-py2.6-linux-x86_64.egg/twisted/internet/posixbase.py", line 128, in __init__ self.i, self.o = os.pipe() OSError: [Errno 24] Too many open files rich(a)black.noir.com> lsb_release -a No LSB modules are available.

[Twisted-Python] multiprocessing capability?
by Darren Govoni 26 Feb '10

26 Feb '10

Hi, I looked at the source for the threads module and wondered if the current Twisted supports Python's (2.6) multiprocessing threading? If not, is there a stable package somewhere that patches Twisted to support this? I saw one from last summer but not sure if its stable. Thanks! Darren

[Twisted-Python] PyCon sprint 2010
by Jonathan Lange 25 Feb '10

25 Feb '10

Hey guys, There's a bunch of cool stuff on http://twistedmatrix.com/trac/wiki/PyconSprint2010 about what we did at the sprint in PyCon. I want to write this up & blog about it for labs.tm.com, but before I do that, I'd like you to look at that page and tell me if anything is missing -- no matter how small. In particular, if you attended and your name isn't there, I want to hear from you. Thanks, jml

[Twisted-Python] Please test 10.0.0pre2!
by Jonathan Lange 25 Feb '10

25 Feb '10

Hello, We inch ever closer to the precipice of our collective doom. The sun will one day burn cold; all things must end; Twisted shall be released. I've uploaded 10.0.0pre2 tarballs to http://people.canonical.com/~jml/Twisted/. The changes since the pre1 are mostly to do with version numbers in documentation, and rolling back a fix for #3292 that introduced failures on our Fedora test suite. I hope to release the final tarball sometime next week. jml

[Twisted-Python] Newbie question: Is this possible with twisted?
by Tim Bordemann 24 Feb '10

24 Feb '10

Hi, first of all: I've no experience with network-programming yet, but need to go in for creating a "simple" client-server application. In the end I'd like to connect a web-form (django) with a twisted-server, which then should do some long-lasting calculations. So far I got a simple xmlrpc-server, which "defers" the calculation to a new thread and a client which sends the initial request to do the calculation. Though I have the problem that the client stays connected until the calculations are done. Could someone tell me if it's somehow possible to disconnect the client right after sending the request to the server? Thanks, Tim
