[ovirt-devel] Re: Python 3 vdsm RPM packages

I've posted a series of patches:

They do a couple of things:
* add an '--enable-python3-build' argument to 'autogen.sh'
* modify 'Makefile.am' so it uses either 'vdsm.spec.in' or
'vdsm-py3.spec.in' file to build RPMs
* preserve the 'vdsm.spec[.in]' filename in dist archives for both py2
and py3 packaging
* fix shebang lines in a dist-hook, so that py3 packages will contain
only '#!/usr/bin/python3' shebangs
* prepare the CI for building py3 packages on fc28
Hi Marcin, cool, thank you!
So actually, if we replace the dummy 'vdsm-py3.spec.in' file
in
https://gerrit.ovirt.org/#/c/98119/ with something useful (be it the
nasty, hacky one, or the shiny, new one), we're ready to build py3
packages.
I've made a dirty one: https://gerrit.ovirt.org/98150 (you can simply
cherry pick the to wherever you need).
However, it doesn't work, it's still built with Python 2 on my Fedora
28. I can see a lot of warning such as
DEPRECATION WARNING: python2 invoked with /usr/bin/python.
Use /usr/bin/python3 or /usr/bin/python2
/usr/bin/python will be removed or switched to Python 3 in the future.
I can see that configure.ac in your patches still uses Python 2. Here
is what I used in my private hacks to change that. Something similar
should be done, depending on --enable-python3-build presence, and with
properly detected Python versions.
Would you like to make the necessary changes or should I make them
myself?
