Re: [Python-Dev] Support for Encrypted Zip as python scripts
by Brett Cannon Sept. 1, 2009

Sept. 1, 2009

There is a standard for encrypting entire zip files. And I was looking at the zip docs the other day and zipfile can already decrypt but not encrypt (assuming my memory is accurate; doing this from my phone on vacation).

how important is setting co_filename for a module being imported to what __file__ is set to?
by Brett Cannon Sept. 1, 2009

Sept. 1, 2009

I am going through and running the entire test suite using importlib to ferret out incompatibilities. I have found a bunch, although all rather minor (raising a different exception typically; not even sure they are worth backporting as anyone reliant on the old exceptions might get a nasty surprise in the next micro release), and now I am down to my last failing test suite: test_import. Ignoring the execution bit problem (http://bugs.python.org/issue6526 but I have no clue why this is … [View More]

3to2 0.1 alpha 1 released
by Joe Amenta Sept. 1, 2009

Sept. 1, 2009

Hello all, I have released the first alpha version of 3to2 after finishing it for my Google Summer of Code 2009(tm) project. You can get the tarball for this release at http://bitbucket.org/amentajo/lib3to2/downloads/3to2_0.1-alpha1.tar.gz. This requires python 2.7, because it requires a newer version of 2to3 than what comes with 2.6. Release notes are in the RELEASE file. Development happens at http://bitbucket.org/amentajo/lib3to2/, and the source code for this release lives at http://… [View More]

Practicality beats purity. ;-) (Especially if it allows importlib to run on older Pythons.) Also, surely you're not worried about *performance* here?

deleting setdefaultencoding iin site.py is evil
by Chris Withers Aug. 31, 2009

Aug. 31, 2009

Hi All, Would anyone object if I removed the deletion of of sys.setdefaultencoding in site.py? I'm guessing "yes!" so thought I'd state my reasons now: This deletion appears to be pretty flimsy; reload(sys) and you have it back. Which is lucky, because I need it after it's been deleted... Why? Well, because you can no longer put sitecustomize.py in a project-specific location (http://bugs.python.org/issue1734860) and because for some projects the only way I can deal with encoded strings … [View More]

Excluding the current path from module search path?
by Chris Withers Aug. 31, 2009

Aug. 31, 2009

Hi All, I'm being bitten by this issue: http://bugs.python.org/issue1734860 I'm not sure I agree with Daniel's closing of it so thought I'd ask here... Am I right in thinking that the general idea is that "the current working directory at the time of invoking a script or interpreter ends up on the python path" or should I be thinking "the directory that a script exists in should end up on the python path"? If the latter, then what happens in the case of just starting up an interpreter? … [View More]

Fast Implementation for ZIP decryption
by Shashank Singh Aug. 31, 2009

Aug. 31, 2009

Hi All, I have implemented the simple zip decryption in C (yes, the much loathed weak password based classical PKWARE encryption, which incidentally is the only one currently supported in python) . It performs fast, as one would expect, as compared to the current all-python implementation. Does it sound worthy enough to create a patch for and integrate into python itself? -- Regards Shashank Singh Senior Undergraduate, Department of Computer Science and Engineering Indian Institute of … [View More]

timed_command.py: consider for inclusion in std. library?
by Charles Waldman Aug. 28, 2009

Aug. 28, 2009

Here's a module "timed_command" I wrote a while ago and is generally useful and might be a good addition to the standard library. It is like commands.getstatusoutput but lets you run a command with an optional timeout. Useful for systems programming where a sub-process might hang. Only works on POSIX, but could perhaps be modified to run on other platforms (I don't have the knowledge of Windows to do this). If you would like to add this to the library, I relinquish all rights to it. Here'… [View More]
