[Fedora-packaging] Request for feedback: %pycached macro for %files section

Hello, we are considering to add a %pycached macro to be used in the %files section: https://src.fedoraproject.org/rpms/python-rpm-macros/pull-request/37 We'd like to receive feedback. We plan to add it to rawhide and backport it to all Fedoras + EPEL7+. 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. -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok
