It is always a pain to use an installer to replace itself. Sorry.
Not your fault, it's just the way it is (combined with my lack of familiarity with any aspect of pip/distribute beyond "pip install pkg_from_pypi").
Double oops. I have pushed bdist_wheel to my cpython fork, but that doesn't take care of the installer. I am definitely interested in porting the distribute version over to Python 3. I just haven't gotten to it.
Hmm, I'm a little confused as to how the bits hang together here. Maybe some clarification would help. How close is the following? pip - your patch for this is to recognise wheel files and use distribute to install them distribute - your patch for this is to add support for installing wheel files (and to add a bdist_wheel command for building them???) wheel - support library for the above, provides functions to work with wheel files Is that close? Assuming it is, I'm not sure I follow what you say in the paragraph above - what is the cpython patch you mention? You can't patch distutils with bdist_wheel as it's feature-frozen, and packaging is being taken out of 3.3 (if it hasn't already). I don't see much point in maintaining a cpython patch that won't get accepted. And I'm not sure what you mean by "the installer". Based on my interpretation of what you say above, the things I see outstanding are: 1. wheel discovery and download from PyPI or local archives (so pip install x will find and download x.whl before/as well as an x sdist) 2. wheel upload to PyPI (probably needs PyPI changes to support the new format) 3. converters to allow people to convert eggs and bdist_wininst binaries to wheel format (otherwise you have a chicken-and-egg problem in that wheels are only good for speeding up installs, rather than for installing things you can't build for yourself) (1) and (2) are longer-term requirements, and (3) may or may not be a key requirement for you - in any case, others who do need the facility could develop these independently. So it seems to me like you're nearly there (assuming the pip and distribute maintainers accept your patches). Paul.
