Versioned pathfixX.Y.py is available in main as well as in
alternative Pythons so this change enables to build
an alternative Python stack without a dependency on the main
python3-devel.
--no-index saves a ~1 minute timeout of pip possibly checking if there is
a newer pip version (in mock with disabled network).
--no-warn-script-location removes a bogus warning that says:
WARNING: The scripts easy_install and easy_install-3.9 are installed in
'/builddir/build/BUILDROOT/python-setuptools-49.2.0-1.fc33.x86_64/usr/bin'
which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning,
use --no-warn-script-location.
See https://fedoraproject.org/wiki/Changes/PythonMacroError
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.
Previous implementation allowed for only one argument to be passed to
the %pycached macro, which made it impossible to combine it with other macros.
Current implementation allows to pass other macros as arguments to
%pycached.
Example:
%pycached %exclude /path/to/foo.py
For macro expansion limitations, the opposite order is not possible.
That is to be documented in the guidelines:

Added some tests.

Usage:
%files
...
%pycached %{python3_sitelib}/foo.py
This will list:
/usr/lib/python3.8/site-packages/foo.py
/usr/lib/python3.8/site-packages/__pycache__/foo.cpython-38{,.opt-?}.pyc
Assuming the Python 3 version is 3.8.
The bytecode files are globbed, their presence is not checked.
This will fail:
%pycached %{python3_sitelib}/foo
error: %pycached can only be used with paths explicitly ending with .py
And so will any of this:
%pycached %{python3_sitelib}/*
%pycached %{python3_sitelib}/foo.*
%pycached %{python3_sitelib}/foo.p?
%pycached %{python3_sitelib}/foo.?y
%pycached %{python3_sitelib}/foo.??
But this will work:
%pycached %{python3_sitelib}/foo*.py
And it will generate the following globs:
/usr/lib/python3.8/site-packages/foo*.py
/usr/lib/python3.8/site-packages/__pycache__/foo*.cpython-38{,.opt-?}.pyc
When used with paths that include Python 3 version, it globs with the version:
%pycached /opt/python3.10/foo.py
Generates:
/opt/python3.10/foo.py
/opt/python3.10/__pycache__/foo.cpython-310{,.opt-?}.pyc
While paths without version have less strict globs:
%pycached /custom/foo.py
/custom/foo.py
/custom/__pycache__/foo.cpython-3*{,.opt-?}.pyc
This will generate a warning in RPM build:
warning: File listed twice: /custom/__pycache__/foo.cpython-38.opt-1.pyc
However it ensures the optimized bytecode is there.
This is mostly used when building Sphinx docs on arched build.
Previously:
PLATFORM=$(python3 -c "import sysconfig; print(sysconfig.get_platform())")
export PYTHONPATH=../build/lib.${PLATFORM}-%{python3_version}
make man
Or:
PYTHONPATH=`realpath ../build/lib.linux*` make
Or:
PYTHONPATH=$(echo $PWD/build/lib.linux-*) make html
Now:
PYTHONPATH=../build/lib.%{python3_platform}-%{python3_version}
This is to ensure the right linker flags get propagated into binaries
accompanying python packages whenever distutils (or similar, env.
variables provided build flags aware) module is delegated to build them
(e.g. https://bugzilla.redhat.com/show_bug.cgi?id=1541106). Instead of
using "%{__global_ldflags}" as the seed for the respective env. variable
one-off application, which would be a direct parallel to "%{optflags}"
seeding CFLAGS, use rather "${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).
