Avoid using space in subproject distutils names

[bersace]

Hi,

Twisted subprojects provides setup.py with name like Twisted Core and archive TwistedCore_11.1.0.tar.bz2.

This break dependencies in regular distutils setup.py and pip usage.

If you use requires=['Twisted Core'], setup.py just fail with error in … setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers

If you use requires=['TwistedCore'], pip will find the archive in a local pypi repository. But it will be installed in Twisted_Core-11.1.0 and with Name: Twisted-Core in the installed EGG-INFO.

Can you rename subprojects to use hyphen instead of space in their name ? I couldn't find the code setting the name= keyword args for setup() (searched twisted.python.dist and setup.py).

Hi Étienne, thanks for your interest in Twisted.

What is the motivation for not considering this a bug in pip? Perhaps Twisted should work around the problem by renaming some packages, but PyPI happily accepts these packages. As a PyPI consumer, pip should be able to deal with exactly the same thing. Has this bug been reported upstream? What do the pip maintainers think?

Apparently this was reported upstream several months ago, < https://github.com/pypa/pip/issues/307>. I'm not really sure how to interpret the last comment, but it sounds like maybe pnasrat thinks it's a legitimate pip bug. As such, I'm inclined to close this as wontfix and let pip deal with it. Thoughts?
