Hi! While preparing the Python 3.15 migration we realized that some Python packages were shipping broken metadata directories, which leads to errors when trying to import these directories with code running on Python 3.15. To avoid shipping any additional broken directories, dh-python now throws an error at build-time when the contents of the directories for two different versions don't match. Unfortunately, contourpy is one of the affected packages and fails to build with the latest dh-python. https://debusine.debian.net/debian/r-python-python3.15/artifact/5177968/ W: dh_python3 fs:157: Paths differ: debian/python3-contourpy/usr/lib/python3.15/dist-packages/contourpy/util/ _build_config.py and debian/python3-contourpy/usr/lib/python3/dist-packages/contourpy/util/_build_config.py E: dh_python3 fs:173: Not everything in 'debian/python3-contourpy/usr/lib/python3.15/dist-packages/contourpy/util' was able to be merged into 'debian/python3-contourpy/usr/lib/python3/dist-packages/contourpy/util'. I: dh_python3 fs:180: Remaining files: debian/python3-contourpy/usr/lib/python3.15/dist-packages/contourpy/util/_build_config.py make: *** [debian/rules:7: binary-arch] Error 1 dpkg-buildpackage: error: debian/rules binary-arch subprocess failed with exit status 2 The _build_config.py files indeed can't be merged. One alternative is to use the new dh-python flag --allow-unmerged-dist-packages to allow this divergence (in this case, it wouldn't lead to broken metadata directories, as they are not in such a directory). Another option would be to patch the code to not need this file at all, as this seems mostly to be for debugging purposes. This is a release critical issue, because we need to rebuild the package for the 3.15 transition. -- Regards, Marga
