I agree - I can't think of any decent use cases for exec() as class namespace - defining functions and classes only works for a subset of … [View More]

Actually, sumo distributions *have* been created; it's just that there are so *many* of them: * Linux distributions * BSD & Mac "ports" systems * ActivePython, the Enthought Distribution, etc. * certain distutils extensions that I shall not name … [View More]

Documenting [C]Python's Internals
by Yaniv Aknin May 26, 2010

May 26, 2010

Hi, I wanted to let python-dev know about a series of articles about CPython's internals I'm publishing under the collective title "Guido's Python"* ( http://tech.blog.aknin.name/tag/guidos-python/). Three articles already were published already, more are planned (mainly focused on CPython/py3k, but comparisons with other implementations may also be covered; we'll see). So far I've done an introduction/whirlwind tour of Py_Main and a two-article in-depth review of the (new-style) object system.… [View More]

__package__ attribute
by Andrew Svetlov May 25, 2010

May 25, 2010

What are expected values for module.__package__? I see two different behaviors: importlib and standard python import. importlib processes __package__ pretty simple and clean: - for toplevel modules __package__ is empty string - for packages it's package name - for modules inside packages it's again package name Standard import follows another strategy: - it tries to setup __package__ only in case of relative import (see first 'if' in import.c:get_parent) - otherwise __package__ is untouched … [View More]

moving issues from argparse tracker to python tracker?
by Steven Bethard May 24, 2010

May 24, 2010

Before I go and add about 30 open issues to the Python tracker, I figured I should ask. What's the normal process for the bug trackers of modules that move to the standard library? I have a few feature requests, etc. for argparse, and I was planning to just copy them over to the Python bug tracker (and close them on the Google code tracker). Is this what people normally do? (It should be easy enough to do - I just don't want to mess up the tracker if this is usually done some other way.) … [View More]

urllib2/urllib incompatibility?
by Vinay Sajip May 24, 2010

May 24, 2010

> Not top-posting, but gmane seems too finicky in this area. I encountered what seems like an incompatibility between urllib and urllib2 in the way they handle file:// URLs, is this a bug? I had a look on the bug tracker and via Google to see if there were prior reports, but perhaps my search-fu is deficient. Here's a console session to illustrate: vinay@eta-karmic:/tmp$ echo Hello, world! >hello.txt vinay@eta-karmic:/tmp$ cat hello.txt Hello, world! vinay@eta-karmic:/tmp$ python … [View More]

Adding a new C API function in 2.6
by Antoine Pitrou May 21, 2010

May 21, 2010

Hello, I would like to check that it's possible to a new C API function in the 2.6 branch, on the basis that it would help solve what seems to be reported as a security problem by several vendors (including Linux distributions) -- see http://bugs.python.org/issue5753 for a thorough discussion. The change is rather minimal at the code level; it adds a new function PySys_SetArgvEx which has an additional flag telling it whether to update sys.path or not. The existing PySys_SetArgv function … [View More]

PEP 3148 ready for pronouncement
by Yannick Loitière May 21, 2010

May 21, 2010

The description of Future.add_done_callback() does not specify whether the callbacks are done in any particular order (such as the order they were added) or not. I'm guessing they are not, but believe it should be documented either way. -- Yannick Loitière
