Make httpbin OS independent again

[5j9]

See https://github.com/kennethreitz/flask-common/issues/4 .
Currently it is not possible to install httpbin on Windows machines. If fails with the following error:

httpbin 0.5.0 didn't have this issue.
Thanks!

This was Kenneth's decision and work, so I'm assigning it to him to decide what to do.

[kennethreitz]

Posix compliance is a fine requirement, for now.

[kennethreitz]

We can work to make flask-common optional though — and not a requirement for windows machines.

[kennethreitz]

anyone want to take a shot at it?

[kevin1024]

I would like to make flask-common optional for another reason: It does not support python 2.6. I am using the httpbin package to test other packages that have python 2.6 support, so I would like httpbin to support it as well.

[sigmavirus24]

@kevin1024 I respect the desire to support old and EOL'd versions of Python. I do this myself, but it's not fair to push that onto other projects. There are versions of httpbin that support 2.6. You can declare a cap that's dependent upon the python_version.

Making things OS independent is a separate task though.

[kevin1024]

@sigmavirus24 fair enough, was mostly thinking about requests. They will need to pin httpbin to make sure their test suite passes so they will miss out on new httpbin features and bugfixes.

[sigmavirus24]

@ldemailly that does not actually contribute to the discussion as to how to make httpbin work on windows.

[5j9]

With #447 being merged httpbin can be installed on Windows once again.

@5j9 feel free to close this issue if all resolved.
