"Don't believe everything you think"

(original) (raw)

Well, I think Numpy is of huge importance to a major Python user segment, the scientific community. I don't know if that makes it 'core', but I strongly agree that it's important.


Better testing is always useful, and more "core", but IMO less important.

Hi all,

this year we have 10-12 GSoC applications that I've put in the "relevant
to core Python development" category. �These projects, if mentors etc
are found, are \*guaranteed\* a slot under the PSF GSoC umbrella. �As
backup GSoC admin and general busybody, I've taken on the work of
coordinating these as a special subgroup within the PSF GSoC, and I
thought it would be good to mention them to python-dev.

Note that all of them have been run by a few different committers,
including Martin, Tarek, Benjamin, and Brett, and they've been obliging
enough to triage a few of them. �Thanks, guys!

Here's what's left after that triage. �Note that except for the four at
the top, these have all received positive support from \*someone\* who is
a committer and I don't think we need to discuss them here -- patches
etc. can go through normal "python-dev" channels during the course of the
summer.

I am looking for feedback on the first four, though. �Can these
reasonably be considered "core" priorites for Python? �Remember, this
"costs" us something in the sense of preferring these over Python
subprojects like (random example) Cython, NumPy, PySoy, Tahoe, Gajim,
etc.

Questionable "core":

2x "port NumPy to py3k" -- NumPy is a major Python module and porting it

Comments/thoughts?

2x "improve testing tools for py3k" -- variously focus on improving test
� � � �coverage and testing wrappers.

� � � �One proposes to provide a nice wrapper to make nose and py.test
� � � �capable of running the regrtests, which (with no change to
� � � �regrtest) would let people run tests in parallel, distribute or

� � � �and run subsets of tests with personal and/or public tags, and
� � � �otherwise take advantage of many of the nice features of nose
� � � �and py.test.

� � � �The other proposes to measure & increase the code coverage of
� � � �the py3k tests in both Python and C, integrate across multiple
� � � �machines, and otherwise provide a nice set of integrated reports
� � � �that anyone can generate on their own machines. �This proposal,

Unquestionably "core" by my criteria above:

3to2 tool -- 'nuff said.

subprocess improvement -- integrating, testing, and proposing some of
� � � �the various subprocess improvements that have passed across this
� � � �list & the bug tracker

IDLE/Tkinter patch integration & improvement -- deal with \~120 tracker
� � � �issues relating to IDLE and Tkinter.

roundup VCS integration / build tools to support core development --
� � � �a single student proposed both of these and has received some
� � � �support. �See http://slexy.org/view/s2pFgWxufI for details.

sphinx framework improvement -- support for per-paragraph comments and
� � � �user/developer interface for submitting/committing fixes

2x "keyring package" -- see
http://tarekziade.wordpress.com/2009/03/27/pycon-hallway-session-1-a-keyring-library-for-python/.

The poorer one of these will probably be axed unless Tarek gives it

strong support.
