@icemac I ran bin/python config-package.py ../../Products.PythonScripts/ --type zope-product

py312 fails on CI, because of buildout/buildout#648 . My understanding is that this error is potentially everywhere in buildout based packages, I don't understand why only 3.12 is affected, but this looks like an old compatible version of setuptools was already installed for other python versions but not for python3.12

in the logs of py311 we can see

py311: freeze> python -m pip freeze --all
py311: pip==24.0,setuptools==69.5.1,wheel==0.43.0,zc.buildout==3.0.1

this is using a compatible old setuptools and test passed for 3.11.

but in the logs of py312

py312: freeze> python -m pip freeze --all
py312: pip==23.1.2,setuptools==70.0.0,wheel==0.43.0,zc.buildout==3.0.1

using incompatible new setuptools and there's this error.

I don't really need this pull request now, I just noticed that there was no python3.12 so I tried to enable it.

All this makes me wonder if it makes sense to pin setuptools < 70 in all zopefoundation repositories for now ?

Hi @perrinjerome zope-product was not yet pinned to setuptools < 69. I just added it. For details see zopefoundation/meta#243 and buildout/buildout#648

So you could pull in the changes in meta and run config again. This time please run it with the --branch option pointing to this branch otherwise it will create a new one.

Thank you @icemac I did not notice that this was already (partially) supported. It should be OK now
