Brand as "3.8", rework %python_provide
- Hardcode the default Python 3 version in the SRPM macros
- Provide python38-foo for python3-foo and the other way around (future RHEL compatibility)
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1812087
$ rpm --eval '%python_provide python38-setuptools'
Provides: python-setuptools = %{version}-%{release}
Provides: python3-setuptools = %{version}-%{release}
Obsoletes: python-setuptools < %{version}-%{release}
$ rpm --eval '%python_provide python3-setuptools'
Provides: python-setuptools = %{version}-%{release}
Provides: python38-setuptools = %{version}-%{release}
Obsoletes: python-setuptools < %{version}-%{release}
$ rpm --eval '%python_provide python39-setuptools'
$ rpm --define 'python3_pkgversion 39' --eval '%python_provide python%{python3_pkgversion}-setuptools'
To make the implementation of %python_provide easier,
any names starting with "python" or "pypy" are recognized as valid arguments.
Previously, this was an ERROR:
$ rpm --eval '%python_provide pythonista'
%python_provide: ERROR: pythonista not recognized.
Now it is a no-op. The behavior was never documented and the change is
backwards compatible for working spec files.
