[Python-Dev] PEP 384 final review (original) (raw)

Extensions built with PyLIMITEDAPI have the python version encoded in it's name. Which abi name should be used for these extensions?

PEP 3149, IIUC, says it should be "abi3". I don't understand what that means, though (with respect to, say, distutils)

- The m and u modifiers in the abi name are complimentary (?)

See above: none of these will be used. Of course, it is possible to name an ABI-conforming extensions with the regular ABI name of the Python release.

- For posix systems the implementation is currently part of the abi name, are PyLIMITEDAPI extensions supposed to be compatible with e.g. PyPy?

That's a choice that PyPy needs to make, of course, but Amaury has indicated that they are interested in doing so.

Should the LIMITEDAPI abi name include the implementation string? - Should the distutils support for LIMITEDAPI be part of the pep, or be implemented later?

Depends on what support you want. Currently, all you need to do is to define Py_LIMITED_API to the preprocessor - this is something that is already supported in distutils.

If you want the support suggested in PEP 3149 (specifying abi=3), it should certainly be implemented in Python 3.2, despite the distutils freeze.
