M2Crypto trunk works, as will the next M2Crypto release. So at this time, you should check out M2Crypto from the Subversion repository. See http://chandlerproject.org/Projects/MeTooCrypto for details on how to get the sources. -- Heikki Toivonen - http://heikkitoivonen.net

newbie qns : how do i use xmldiff?
by sWrath swrath Nov. 5, 2010

Nov. 5, 2010

Hi , I am pretty new to python , and reading up on it. Basically I am trying to compare xml files . I know difflib have it but it does not work out as expected. I was looking at xmldiff , unfortunately I am not able to find documentation how to call it from python. Anyone knows a link or doc to it as I have been looking high and low for few days? lastly , is there a py (or algorithm) where it behaves exactly like diff ? Greatly appreciated. Thanks john

minimal D: need software testers
by Kruptein Oct. 28, 2010

Oct. 28, 2010

Hey, I've released the second alpha for minimal-D a program I've written in python which should make developing easier. I need people to test the app on bugs and give ideas. It is written in python using the wxPython toolkit and is linux-only. (using on windows is on own risk) You can download a .deb or a .tar.gz from http://launchpad.net/minimal

We've been through this.

Currently being debated. See bug tracker.) The really stupid thing about the current SSL module is that it accepts a file of root certificates as a parameter, but ignores it. So it creates the illusion of security without providing it. As someone pointed out, the current SSL module "lets you talk encrypted to your attacker". John Nagle

Catching a SIGSEGV signal on an import
by Ryan Oct. 19, 2010

Oct. 19, 2010

Is there anyway to catch a SIGSEGV signal that results from an import? I'd like to get a list of all modules on the sys.path. The module pkgutil has a nice method, walk_packages, to do just that. But, there is a third party extension that throws a SIGSEGV when imported. I tried to create a signal handler with the signal module like: #!/bin/env python import pkgutil import signal import traceback def handler(signal, stackframe): raise ImportError # Handle seg faults that may occur during an import signal.signal(signal.SIGSEGV, handler) if __name__ == "__main__": goodMods = [] def onerror(pkgName): sys.stdout.write('Unable to import package %s\n' % pkgName) traceback.print_exc(file=sys.stdout) sys.stdout.write('\n') #sys.stdout.flush() for importer, mod, ispkg in pkgutil.walk_packages(path=None, onerror=onerror): goodMods.append(mod) for m in goodMods: sys.stdout.write(m + '\n') sys.stdout.flush() This sometimes works. But, since SIGSEGV is asynchronous it is not guaranteed to work all the time. In general, is there anyway to catch a SIGSEGV on import? If so, is there a way to use that with pkgutil.walk_packages to get all the modules on sys.path? Thanks, Ryan

Oct. 18, 2010

Hey, I've finished my second version of deditor, a python text-editor for python under linux. It offers some python-only features like an interpreter, a code- analyzer, syntax-highlighting,... Are there some people in here who would like to test the app? (and maybe even help spread it) more info can be found on launchpad: https://launchpad.net/deditor or you can mail me darragh.ssa(a)gmail.com
