Description Tomas Orsava 2016-04-01 15:44:22 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 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!

The Python addon, included in the main RPM, is currently built only for Python 3.

Comment 2 Tomas Orsava 2016-04-06 10:42:53 UTC

If you take a look at the spec file: http://pkgs.fedoraproject.org/cgit/rpms/Io-language.git/tree/Io-language.spec#n29

There's a build dependency on the `python-devel` package, which is for Python 2. And indeed if I build the package in koji and then list the dependencies of the resulting RPM `rpm -qRp Io-language-extras-20151111-0.e64ff9.fc25.1.x86_64.rpm` it finds a dependency on `libpython2.7.so.1.0()(64bit)`.

Could you change the BuildRequires to `python3-devel`? I tested it and it fixes the issue.

Comment 3 Gwyn Ciesla 2016-04-06 13:31:28 UTC

Ah, so it does.  Done in rawhide, thanks!

Comment 4 Tomas Orsava 2016-04-06 13:33:25 UTC

And thank you for your time!
