Tracker reviews workflow and flags
by anatoly techtonik March 20, 2010

March 20, 2010

I want to push some of my patches before 2.7 and use 5-1 rule for that, but I can't come up with any review workflow other than mailing status of my comments to the issues here. I can't mark issues in any way. How about giving users ability to set flags or keywords? Maybe entering a separate field like "Review status"? Real world example with issue8151. It is an issue with a trivial patch in it. Everything what is needed is to dispatch it to stable `commit queue` and port to trunk. It is not '… [View More]

Needs Review: 2to3 fixer for sys.exitfunc to atexit.
by Sean Reifschneider March 20, 2010

March 20, 2010

Issue 2356 ( http://bugs.python.org/issue2356 ) looks like it has a patch candidate, but just needs review to put in place. Seems like it may be low hanging fruit critical that just needs a quick review to either apply or at least get back to the folks who are working on a patch. Thanks, Sean -- The most important thing in communication is to hear what isn't being said. -- Peter Drucker Sean Reifschneider, Member of Technical Staff <jafo(a)tummy.com> tummy.com, ltd. - … [View More]

"expected a character buffer object" messages
by aditya bhargava March 19, 2010

March 19, 2010

I found an old thread on Python-Dev that suggested replacing the error "TypeError: expected a character buffer object" with something more helpful for non-experts like "expected a string or character buffer". Here's the thread: http://mail.python.org/pipermail/python-dev/2006-May/065301.html I think this is an excellent idea, but besides this ticket: http://bugs.python.org/issue6780 I haven't seen anything further about it. Does anyone know the status on this? It would be nice to have a more … [View More]

3.1.2 tagging delayed a little
by Benjamin Peterson March 19, 2010

March 19, 2010

Pending the resolution of a few Mac OS issues (#8068, #8069, and #8133), I'm not going to tag the release at the moment. Hopefully, we'll still be able to have a release in the next week. -- Regards, Benjamin

binary operation heuristics -- bug or undocumented?
by Alex A. Naanou March 19, 2010

March 19, 2010

Hi, A friend of mine stumbled upon the following behavior: ---cut--- >>> class A(object): pass ... >>> class B(object): ... def __add__(self, other): ... print 'B: adding B and %s objects.' % other.__class__.__name__ ... >>> class C(object): ... def __radd__(self, other): ... print 'C: adding C and %s objects.' % other.__class__.__name__ ... >>> a, b, c = A(), B(), C() >>> b + c B: adding B and C objects. >>> a +… [View More]

Is Scala better than Python ???
by OMEGA RED March 18, 2010

March 18, 2010

To All, I have done some more review of python and Scala and I am very impressed with both languages. However, it seems as though that Scala is far more able to support parallel processing than Python ?? Is this true ?? O.R.

Removing Windows 95-related code in posixmodule.c
by Tim Lesher March 17, 2010

March 17, 2010

Now that Windows 9x is no longer supported (per PEP 11), would it be appropriate to replace the ANSI ("A") versions of Windows OS calls in posixmodule.c with their Unicode ("W") equivalents and remove the unicode_file_names() function that determines which version to call? There are a number of places in that module where we try to decide whether to call ANSI or UNICODE versions (because only the ANSI versions were fully supported on Windows 9x). This is still fine on Win32, where the ANSI … [View More]
