Sorry for late reply.
From the Python packaging:
# Must do the python2 install first because the scripts in /usr/bin are
# overwritten with every setup.py install, and in general we want the
# python3 version to be the default.
%py2_install
%py3_install
I don't think that binaries of python module should be already switched to
the state that non versioned binary is python3 binary.
This problem is covered
extensively in the guidelines:
If the executables provide the same functionality independent of
whether they are run on top of Python 2 or Python 3, then only one
version of the executable should be packaged. On releases up to and
including F21, this was the python 2 implementation. Python3 should
be used in F22 and later if supported by upstream. [...]
Transitioning from python2 to python3 is left to individual package
maintainers[...]
The switch as "default" was accepted as
https://fedoraproject.org/wiki/Changes/Python_3_as_Default.
While /usr/bin/python points to /usr/bin/python2 and python-foo
provides python2 version
of the foo package I would expect binary foo to run on python2.
Fedora is finally
switching to Python 3. E.g. /usr/bin/dnf now uses Python 3,
and a lot of other things also.
This applies for modules binaries such as pytest (nosetests, pip,
...) where is
difference between running python2 and python3 version of the binary.
For those
cases guidelines say that both versions should be packaged.
Currently we should have non versioned binaries to run on python3
only for python
applications (devassistant) where both python2 and python3 version of the application
provide same functionality.
Yes.
Therefore I suggest to switch order of pyX_install macros.
Eeee, no. Let's use Python 3 by default.
