It's easy enough to change in distlib, but the use of "probably" in that PyPy-specific sentence in PEP 425 makes that statement as a whole less than definitive. Indeed, the clear specification is to use py_version_nodot, which on PyPy 1.9 at least gives me '27'. So, if we should be using the PyPy version number, I think PEP 425 should explicitly say something like
On PyPy, use ''.join(sys.pypy_version_info[:2]) Or whichever PyPy-specific API is supposed to be used to get this information, if not the one I've suggested.

As it stands, I will be very unsuccessful if bdist_wheel produces pp27 tags and my downloader only looks for distributions tagged with pp22. :-) Happy to send out some pull requests. pip, wheel and distlib all get this wrong. AFAICT pip/wheel use the same pep425tags code. Does that have a shared home? ~brian On Tue, Jan 21, 2014 at 8:30 AM, Daniel Holth <[email protected]> wrote: That should probably be considered a bug in bdist_wheel. I don't think there has been any movement on alternate implementations choosing what they want their PEP 425 tags to be. Are you implementing your own wheel generator?
