Description Petr Viktorin 2016-07-30 09:04:03 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!

Updated spec file

Hi Tomáš,

may I ask you to review the updated spec file patch which I have adjusted according to the request of Matthias (bug #1311552)?

Thank you.
Comment 4 Tomas Orsava 2016-08-05 12:59:07 UTC 
Hi Jan!

The patch looks great, there's just one tiny detail:

In the original spec file, in the %prep section there's the following:

# Remove bundled egg-info
rm -rf %{pypi_name}.egg-info

That's usually a good idea, because the .egg-info gets generated anew during the build. Therefore I suggest leaving this line in the spec file.

Apart from that, everything looks superb!
Comment 5 Jan Beran 2016-08-05 13:54:32 UTC 
Hi Tomáš,

thanks for your review.

As I understand from the recommendation of Matthias (bug #1311552), if %autosetup replaces %setup then "rm -rf %{pypi_name}.egg-info" command is not required any more.
Comment 6 Tomas Orsava 2016-08-05 16:18:46 UTC 
Oh, I did not know that, my apologies!

In that case, the patch looks good to me!
Comment 7 Matthias Runge 2016-08-08 06:17:41 UTC 
Jan, Tomas,

%autosetup replaces %setup. I don't remember the reasons.

Removing the upstream provided egg-info is discouraged anyways. That was a change around 2 years ago, driven by kchamart, but neither he nor me remember the the reasons for that anymore. The recommendation to remove egg-info has been removed from python packaging guidelines then.
Comment 8 Matthias Runge 2016-08-08 07:26:19 UTC 
Difference between %setup and %autosetup is, that autosetup applies patches listed in %patch???.
Comment 9 Lumír Balhar 2016-08-15 10:56:20 UTC 
Hello Matthias.

Yes, differences between %setup and %autosetup are:
- %autosetup applies patches (Patch0, Patch1 ...) automatically
- %autosetup has option -q (quiet) enabled by default
Comment 10 Lumír Balhar 2016-08-30 06:49:27 UTC 
If maintainer has nothing against, we can push this reviewed patch after a week.

Which patch are you speaking of? The last patch is marked obsolete here.

I believe you are mistaken, the last patch [0] is not obsoleted.

committed the patch and fixed the build afterwards,

mrunge's python-django-pyscss-2.0.2-4.fc26 completed http://koji.fedoraproject.org/koji/buildinfo?buildID=795604

Thanks!
