python-polib supports Python2 and Python3

2012-11-10 Thread Dylan Semler 
I believe polib provided by the current python-polib rpm supports both
python2 and python3[1].  However, the rpm only provides source in the
python2.7/site-packages directory and there is no python3-polib rpm.

I don't know the correct way to handle these types of packages, but should
the polib rpm be updated to place symlinks of the polib files from the
python2.7/site-packages to python3.2/site-packages?  Or should a
python3-polib rpm be created using the same source?

I've tested the symlink workaround by successfully building dupeguru
(written in python3 and requiring polib).  I don't have any specific
experience with polib to test further.

Thanks,
Dylan

[1] From the changelog from version 0.7:  "This version adds support for
python 3 (thanks to Vinay Sajip). polib now supports out-of-the-box any
version of python ranging from 2.4 to latest 3.X version. polib is now 5
years old ;) so the 0.7.X branch will be the last before the 1.X stable
branch."

Most of the needed information is documented here:

http://fedoraproject.org/wiki/Packaging:Python#Subpackages

It basically installs two copies of the files, one for the python2
subpackage and one for the python3 subpackage.  It uses the typical python
setup.py build to do that, though, because many projects don't work from
a single set of source files -- the sources need to be converted using 2to3
or similar before they'll run on python3.
