add Python 3 & update version none

Description Petr Viktorin (pviktori) 2016-07-04 09:19:53 UTC 
Upstream, this software supports Python 3. Please provide a Python 3
package for Fedora.


According to the Python packaging guidelines [0], software must be
packaged for Python 3 if upstream supports it.
The guidelines give detailed information on how to do this, and even
provide an example spec file [1].

The current best practice is to provide subpackages for the two Python
versions (called "Common SRPM" in the guidelines). Alternatively, if
nothing depends on your Python2 package, you can just switch to Python 3
entirely.

It's OK to do this in Rawhide only, however, it would be greatly
appreciated if you could push it to Fedora 24 as well.


If you need more instructions, a guide for porting Python-based RPMs is
available at [2].
If anything is unclear, or if you need any kind of assistance with the
porting, you can ask on IRC (#fedora-python on Freenode), or reply here.
We'll be happy to help!

Comment 1 Jan Kurik 2016-07-26 04:55:41 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 25 development cycle.
Changing version to '25'.

add Python 3 & update version

Hi Pradeep,
here is the change needed to add Python 3 support and update the version. Could you please review it and do the update?
There is an issue on F24 - problem witch BuildRequire: python-pycadf, it can not be found. On 25 and rawhide works fine.

Koji scratch build: http://koji.fedoraproject.org/koji/taskinfo?taskID=15461555

Also tested in Mock (fedora-25-x86_64, fedora-rawhide-x86_64).
Comment 3 Pradeep Kilambi 2016-09-14 18:34:39 UTC 
Thanks. I just applied your patch and tried building and i get a error with BuildRequires: python3-pycadf .

Does python3-pycadf exist? i get package not found. I can pull in python-pycadf though.
Comment 4 Pradeep Kilambi 2016-09-14 18:39:21 UTC 
also if i remove python3-pycadf build requires it moves forward but fails with

size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic'
+ /usr/bin/python2 setup.py build '--executable=/usr/bin/python2 -s'

looks like we are missing python-iso8601 requires too.
Comment 5 Pradeep Kilambi 2016-09-14 19:03:12 UTC 
ok ignore the above iso8601 error, looks like i needed to update pbr. If we can confirm on python3 package for pycadf, i'll push this out and build.

python3-pycadf exists in rawhide so far.
