Hello Fedora Python package maintainers!

This is an announcement of a mass package renaming:
Python 2 binary packages will be renamed to python2-*.

This will happen soon after the F27 branching on August 15th.

Currently ~1330 source packages already generate a binary package with
the python2- prefix, and 835 remain to be updated. The spec files for
approximately 740 packages will be renamed, and 95 will be left for
fixing by maintainers or proven packagers.

At the end of this e-mail are two lists of maintainers and packages:

List 1. for those packages which will be taken care of by the mass remaining
    Patches: https://in.waw.pl/~zbyszek/fedora/pyrename/

    Maintainers don't have to do anything.

+%package -n python2-atpy
+Summary: %summary
+Requires: numpy python-astropy
+%{?python_provide:%python_provide python2-atpy}
+# Remove before F30
+Provides: ATpy = %{version}-%{release}

This looks incomplete & broken to me.

The Provides satisfies any dependancies on the old name, but you're
missing an Obsoletes to tell RPM the upgrade path. Trying to installing
the new python2-libvirt RPM on an existing system fails because it
clashes with libvirt-python.
Good catch. Obsoletes: python-libvirt is generated by %python_provide,
but I forgot to add Obsoletes: libvirt-python.
Thanks, I'll fix this and other packages in the same situation.
I added that. New patches are in https://in.waw.pl/~zbyszek/fedora/pyrename/.

This new Obsoletes is generated with %{_isa}, and I also added
%{_isa} to the matching Provides.


IIRC - Obsoletes are done only against package names, not "provides", so the Obsoletes with %{_isa} is not needed. This is why %python_provide doesn't generate it with %{_isa} anymore.
