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 function and class definitions However, if exec() ran as function namespace instead, then the locals dictionary will contain all the definitions from the exec()'d code block, and only those definitions. Very useful. This is a major use case for exec() - defining code from strings (e.g. enabling you to store python code in the database), and using it at runtime. It seems to me this must have been the point of locals in the first place. If you just use globals, then your definitions exist amongst a whole bunch of other python stuff, and unless you know in advance what was defined in your code block, its very difficult to extract them.

Re: [Python-Dev] Sumo

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 When the idea of "sumo" distributions were first being batted around (10-12 years ago?), I'm not sure even *distutils* existed yet, let alone any of this other stuff. I mean, yeah, the port systems and distros existed, but their coverage wasn't nearly as good as it is today.

Documenting [C]Python's Internals
by Yaniv Aknin 26 May '10

26 May '10

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. I'm sharing this with you (and hope you care) due to three reasons, probably in escalating importance: (a) Maybe some of python-dev's readers would be interested (possibly the newer and more silent members). (b) Maybe my scales are wrong, but I was a bit surprised by the number of readers (>20,000 in the past two weeks); I wouldn't want to mislead such a reader base and would be happy if a veteran here would be interested in aiding by technically proofing the material (shan't be too hard I hope, feel free to contact me directly if qualified and interested). (c) While the content is currently geared to be blog-oriented, if it's found worthy by the group I'd be delighted to formulate it into something more 'reference-material-ish' and give it back to the community. I found no centrally organized CPython-internals material other than bits and pieces (descrintro, eclectic blog posts, lectures, C-API reference, etc), and I hope maybe something like this could be featured more officially on python.org, with the relevant 'this is subject to change' disclaimers (can be a document for new contributors, for pure Python programmers who're just interested, or for whatever we decide). Questions? Comments? - Yaniv * think "Tim Berners-Lee's Web" or "Keanu Reeves' Green Gibberish", see the first post for details

__package__ attribute
by Andrew Svetlov 25 May '10

25 May '10

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 and None by default. For me importlib's way is better. I don't see any PEP specifying __package__ behavior.

moving issues from argparse tracker to python tracker?
by Steven Bethard 24 May '10

24 May '10

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.) Thanks, Steve -- Where did you get that preposterous hypothesis? Did Steve tell you that? --- The Hiphopopotamus

urllib2/urllib incompatibility?
by Vinay Sajip 24 May '10

24 May '10

> 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 Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15) [GCC 4.4.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import urllib,urllib2 >>> s = 'file:////tmp/hello.txt' >>> f1 = urllib.urlopen(s) >>> f1.read() 'Hello, world!\n' >>> f2 = urllib2.urlopen(s) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.6/urllib2.py", line 124, in urlopen return _opener.open(url, data, timeout) File "/usr/lib/python2.6/urllib2.py", line 389, in open response = self._open(req, data) File "/usr/lib/python2.6/urllib2.py", line 407, in _open '_open', req) File "/usr/lib/python2.6/urllib2.py", line 367, in _call_chain result = func(*args) File "/usr/lib/python2.6/urllib2.py", line 1240, in file_open return self.parent.open(req) File "/usr/lib/python2.6/urllib2.py", line 389, in open response = self._open(req, data) File "/usr/lib/python2.6/urllib2.py", line 407, in _open '_open', req) File "/usr/lib/python2.6/urllib2.py", line 367, in _call_chain result = func(*args) File "/usr/lib/python2.6/urllib2.py", line 1287, in ftp_open raise URLError('ftp error: no host given') urllib2.URLError: <urlopen error ftp error: no host given> >>> Anyone seen this before?

Adding a new C API function in 2.6
by Antoine Pitrou 21 May '10

21 May '10

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 unconditionally updates sys.path, which can allow shadowing of stdlib or third-party library modules by an attacker. Thank you Antoine.

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
