Re: [Distutils] If you want wheel to be successful, provide a build server.

I want to get something setup that would allow people to only need to upload a source release to PyPI and then have wheels automatically built for them (but not mandate that- Projects that wish it should always be able to control their wheel generation). I don’t know what that would specifically look like, if someone is motivated to work on it I’m happy to help figure out what it should look like and provide guidance where I can, otherwise it’ll wait until I get around to it.

One first step towards this that's a natural follow-on to the manylinux work might be to define a overall build configuration file / format and process for automating the whole wheel build cycle (i'm thinking of something modeled after conda-build) that would, among other things

for potentially multiple versions of python: - run `pip wheel` (or setu.py bdist_wheel) to compile the wheel - run `auditwheel` (linux) or `delocate` (osx) to bundle any external libraries

Maybe there could be a way to say "the most recent release that has a wheel for my platform". That would help with the problem of binaries not being available concurrently with a new source distribution.

Yes, that would certainly help get over some of the immediate problems.

Sorry for my ignorance - but does ``--only-binary`` search for an earlier release with a binary or just bomb out if the latest release does not have a binary? It would also be good to have a flag to say "if this is pure Python go ahead and use the source, otherwise error". Otherwise I guess we'd have to rely on everyone with a pure Python package generating wheels.

I believe it would find the latest version that has a wheel available, I could be misremembering though.

...

It would be very good to work out a plan for new Python releases as well. We really need to get wheels up to pypi a fair while before the release date, and it's easy to forget to do that, because, at the moment, we don't have much testing infrastructure to make sure that a range of wheel installs are working OK.
