Package: pybuild-plugin-pyproject Version: 5.20221122 Severity: important TL;DR: plugin_pyproject.py installs files listed under [options.data_files] (such as manpages) in an unexpected place, different than pip would have.
Dear Maintainer, First, a disclaimer: I have almost zero experience and knowledge about Python project installation tools, and setup.cfg in particular. So please let me know if I'm talking nonsense here. A bit of background: Upstream of ledgerhelpers has recently switched from setup.py to pyproject.toml + setup.cfg. The latter file contains a bunch of data files (desktop files, documentation, and manpages) which are supposed to be installed in FHS-compliant places under /usr/share: https://github.com/Rudd-O/ledgerhelpers/blob/48ba347b3a81b8759850e5b45ffff4bb91c03bce/setup.cfg#L38-L58 This is indeed more or less when these files land when the application is installed using pip or the RPM package prepared by the upstream maintainer. However when I tried to adapt my debian package to the current upstream version, the pyproject plugin for pybuild installs them together with the python modules. So for example the manpages end up in somewhat weird location like /usr/lib/python3.10/dist-packages/share/man/man1 I had a look at the code, and I think this FIXME is exactly about this issue I'm having: https://salsa.debian.org/python-team/tools/dh-python/-/blob/master/dhpython/build/plugin_pyproject.py#L131-132 If I correctly understand what is going on in build_step2() and install() then I think data_files should be treated similarly to scripts: unpacked into a separate directory and then copied into something like: args['destdir'] + paths['data'] While the data_files concept seems to be deprecated according to https://setuptools.pypa.io/en/latest/userguide/declarative_config.html#opt-4I and does not have a replacement judging by https://github.com/pypa/packaging-problems/issues/72 I think it would still make sense to try and imitate what pip is doing at the moment. -- System Information: Debian Release: bookworm/sid APT prefers testing-debug APT policy: (500, 'testing-debug'), (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 5.19.0-2-amd64 (SMP w/4 CPU threads; PREEMPT) Locale: LANG=pl_PL.UTF-8, LC_CTYPE=pl_PL.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages pybuild-plugin-pyproject depends on: ii dh-python 5.20221122 ii python3-build 0.7.0-4 ii python3-installer 0.5.1+dfsg1-2 ii python3-tomli 2.0.1-1 pybuild-plugin-pyproject recommends no packages. pybuild-plugin-pyproject suggests no packages. -- no debconf information
