[Twisted-Python] plugin vs. dropin
by Phil Christensen Nov. 28, 2003

Nov. 28, 2003

i was going through the docs, and i found the two classes in twisted/python/plugin.py, and i was wondering what the difference is between the two. i'd like to be able to make a sort of plugin that when the plugin package is in the path, it interacts in arbitrary ways with my main application. however, i don't think i'd want it to appear in mktap, as that doesn't really make sense in this situation.....or does it? -phil

[Twisted-Python] Fwd: Seems like the remote stuff works almost TOO well!
by Glyph Lefkowitz Nov. 28, 2003

Nov. 28, 2003

I am not sure if this was just the most creative unsolicited mail I ever received, or if it's a complaint from an unsuspecting user. I think the "werewolf" comment is from the "AUSPEX" capability of the POP3 server. Have crackers been using Twisted for some nefarious scheme?

[Twisted-Python] protocol factory interfaces?? (FTP)
by Jonathan Simms Nov. 26, 2003

Nov. 26, 2003

Is it possible (or even useful) to have a protocol which expects the factory which builds it to have a specific interface? (as the protocol has a .factory attribute and therefore can access methods and attributes on it's factory) or must all twisted.protocols be able to work with internet.protocol.Factory() off-the-shelf?

[Twisted-Python] Woven application, objects not collected.
by Syver Enstad Nov. 25, 2003

Nov. 25, 2003

I have a serious problem with some woven applications where deferreds and their results returned from wmfactory_ methods are not garbage collected. They just stack up in gc.garbage. The python documentation states that the contents of gc.garbage are objects that are part of a cycle can't be collected because they have a __del__ method. Any help on this issue would be really appreciated.

[Twisted-Python] Why would getUser()/getPassword() return ""?
by Stuart Hungerford Nov. 25, 2003

Nov. 25, 2003

Hi all, Before I move onto learning about cred, guard and more sophisticated authentication schemes, I'm trying to get a simple example working with basic HTTP authentication. I have a resource subclass who's render() method checks the values of request.getUsername() and request.getPassword(): class request_create(twisted.web.resource.Resource): isLeaf = 1 addSlash = 0 def render(self, request): if (not request.getUser()) or (not request.getPassword()): … [View More]

[Twisted-Python] how to use the twisted logging facility?
by John Benson Nov. 25, 2003

Nov. 25, 2003

I've looked at the log module documentation of twisted.python and more or less guess that you can redirect the print statement to a log, and somehow observe the stuff that is being logged in case you want to write it somewhere else too. I was able to redirect the Python print statement to a disk file, but am at a loss when it comes to properly configuring and installing an observer. I want to observe the logging stream and throw it out to a Tkinter text window. Thanks in advance for any advice.

[Twisted-Python] Informal poll, and Resolution of earlier post Fw: help please: trouble installing twisted python on Windows 2000 Pro, but not Windows XP Pro
by John Benson Nov. 25, 2003

Nov. 25, 2003

Hi, I'm answering my own post for the benefit if future newbies: I was having an awful time installing twisted on a W2K Professional machine. In desperation, I uninstalled all the Python things (Python 2.3 and Pythonwin), reinstalled Python 2.3, installed Twisted, and then Pythonwin and all the installations seemed to go OK. Plus I rebooted in between the installations because I didn't have a rubber chicken handy to wave over the computer. Not much of a technical note, but there it is. … [View More]
