[Python-Dev] Proposing PEP 386 for addition (original) (raw)

Hello,

On behalf of the Distutils-SIG, I would like to propose PEP 386 for inclusion in the sdtlib, and have a final discussion here on Python-dev.

http://www.python.org/dev/peps/pep-0386

This PEP has been discussed for some time in Distutils-SIG, and we agreed there that it's important to have it accepted for the future of packaging because:

1/ it will offer interoperability for all Python package managers out there. (namely: Distutils, Distribute, Setuptools, Pip, PyPM) 2/ it will provide a reference for OS packagers, so they can translate automatically Python distributions versions in their own schemes.

Choosing a schema was quite controversial because every development team have their own version scheme. But notice that it is not in the scope of this PEP to come up with an universal versioning schema, intended to support many or all existing versioning schemas. There will always be competing grammars, either mandated by distro or project policies or by historical reasons and we cannot expect that to change.

The goal of this PEP is rather to provide a standard reference schema that is able to express the usual versioning semantics, so it's possible to parse any alternative versioning schema and transform it into a compliant one. This is how OS packagers usually deal with the existing version schemas and is a preferable alternative than supporting an arbitrary set of versioning schemas.

I believe that the current situation is as close to consensus as we will get on distutils-sig, and in the interests of avoiding months of further discussion which won't take things any further, I propose to allow final comments from python-dev and then look for a final decision.

Regards Tarek
