pip wheel installer doesn't like case-sensitive extra requirements.

See original GitHub issue

I have a package that uses some extra requirements with mixed-case identifiers.

When I install the wheel from PyPI via pip install aiomas[MsgPack], the extra requirements don’t get installed.

It works when I install the source dist via pip install --no-use-wheel aiomas[MsgPack] or from source via pip install -e .[MsgPack].

I have:

pip 6.0.8
setuptools 12.0.5

Maybe it’s a problem with case-(in)sensitivity?

@dholth Would that help in this case? The problem is with the extras requested from the command-line.

A quick fix would be to run the extras through pkg_resources.safe_extra; attached is a completely untested patch as demonstration. pip-req_set-2518.patch.txt

A more thorough patch would include additional tests and probably examine the other use of .extras in add_requirement, around line 255.

A better fix would be to refactor _prepare_file; at ~250 lines, it’s way too long. The extras processing itself could easily be extracted as it needs only dist and req_to_install.
