Adopt a consistent POSIX layout

Feature or enhancement

Proposal:

Currently, the Python installation directory for stdlib/platstdlib and purelib/platlib is defined as {implementation_lower}{py_version_short}{abi_thread}, and for include/platinclude as {implementation_lower}{py_version_short}{abiflags}.

I would like to make it consistent with {implementation_lower}{py_version_short}{abiflags}.

Currently, I believe this will mostly affect debug builds, which will receive their own separate directory.

Has this already been discussed elsewhere?

Links to previous discussion of this feature:

In https://github.com/python/cpython/issues/121103, we added {abi_thread}.
In https://github.com/python/cpython/issues/127294, we discuss some of the impact of mixed installations.

Commencez par examiner la discussion dans les issues 121103 et 127294, puis suivez la manière dont les chemins d’installation de stdlib, platstdlib, purelib, platlib, include et platinclude sont définis. Vérifiez les effets sur les installations de débogage et mixtes ; le travail est terminé lorsque les chemins concernés utilisent systématiquement {implementation_lower}{py_version_short}{abiflags} sans casser ces cas.
