Description Tim Orling 2022-02-22 23:03:39 UTC 
The current recipetool code only understands 'distutils' and legacy 'setuptools' (setup.py) invocations. We need to check for presence of pyproject.toml and then _if_ it supports proper PEP-517 backend, make a stab at DEPENDS and RDEPENDS.

While we are at it, we should probably remove 'distutils' support completely?

Backport to 3.5 if not too invasive.
Comment 2 Tim Orling 2022-02-24 16:38:09 UTC 
The first thing that must be changed is the logic at:
https://git.yoctoproject.org/poky/tree/scripts/lib/recipetool/create_buildsys_python.py#n158

        # Check for non-zero size setup.py files
        setupfiles = RecipeHandler.checkfiles(srctree, ['setup.py'])
        for fn in setupfiles:
            if os.path.getsize(fn):
                break
        else:
            return False

This also needs to look for pyproject.toml and setup.cfg files. Based on what files are found, make a decision of how to proceed.

For instance, if a pyproject.toml is present, has a [build-system] section and a build-backend that we know about (have a bbclass for) then the recipe should inherit e.g. flit_core, setuptools_build_meta or poetry_core (WIP).

Looking for dependencies will also need more than one way to handle it, as recipes without setup.py might include such info in setup.cfg or in pyproject.toml.
