While doing it, make %python macros more consistent with %python3 macros,
mostly wrt whitespace but also to use python -m pip over plain pip etc.
One significant change is the removal of sleeps from python macros,
this could affect packages that use python macros to build for Python 2
while also using python3 macros to build for Python 3.
In reality, I consider that unlikely. The sleep in python2 macros stays.
The --strip-file-prefix option was already removed from %pyX_install_wheel
but we forgot to remove it from %py_install_wheel.
- 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.
Based on recent changes in 04769fa014,
packagers might want to use:
%{?python_provide:%python_provide python2-foo%{?_isa}}
...for backwards compatibility. However the macro adds obsoletes and
since RPM 4.15, obsoletes with %{?_isa} are not possible:
Only package names are allowed in Obsoletes: Obsoletes: python-foo(x86-64) < ...
To allow such usage, %python_provide now only obsoletes if the argument
does not end with ")".
In rpm 4.15 those are no longer defined.
The meaning of "python" is derived from %__python - and that errors by default
unless user defined.
Example usage:
%global __python /usr/bin/pypy3
...
%files
%{python_sitelib}/foo/
This is needed so people can do things like:
%if %{with python3}
%global __python %__python3
%else
%global __python %__python2
%else
And than just use %__python, %py_build, %py_install,
%python_sitelib, ...
This is to ensure the right linker flags get propagated into binaries
accompanying python packages whenever distutils (or similar, env.
variables provided build flags aware) module is delegated to build them
(e.g. https://bugzilla.redhat.com/show_bug.cgi?id=1541106). Instead of
using "%{__global_ldflags}" as the seed for the respective env. variable
one-off application, which would be a direct parallel to "%{optflags}"
seeding CFLAGS, use rather "${RPM_LD_FLAGS}" and "${RPM_OPT_FLAGS}",
as these are not directly bound to macros out of rpm proper (like
it would have been, e.g., on redhat-rpm-config package otherwise).
