Hello Python RPM packagers,
based on some discussion in the "F35 Change: Python Packaging Guidelines
overhaul (System-Wide Change proposal)" thread [0], I've drafted a macro that
can help to test-import a Python module in %check when no other tests exist or
are when they cannot be executed during build [1].
The semantics is quite simple:
%check
%py3_check_import mymodule mymodule.submodule
When all listed modules are successfully imported, "nothing happens", when at
lest one fails to import, the entire build fails. The above line is translated
very-roughly to `python3 -c 'import mymodule, mymodule.submodule'` (see the
implementation [0] for more accurate representation). Given the Python
semantics, it is possible to use commas as module separators as well (but no
parentheses).
The %buildroot's %pythn3_site{lib,arch} is added to PYTHONPATH.
The runtime dependencies are obviously needed for this to work, so they need to
be manually BuildRequired or even better, generated in %generate_buildrequires
via `%pyproject_buildrequires -r` to use this macro.
The macro can be used repeatedly when importing multiple modules at once is
undesired (e.g. when only one module can be imported from the same Python
interpreter):
%check
%py3_check_import mymodule.either
%py3_check_import mymodule.or
Before I merge this and backport to all Fedoras and EPELs, I'd like to know:
- Do you have better ideas for the macro name?
- Do you have better ideas for the macro semantics?
