Remove transitional stuff from setup.py?

Hi

Calling setup() in setup.py twice is weird and confuses pip.

One example is if you try to use wheels. We use wheels to speed up our Travis CI - our requirements.txt is fetched and compiled once, and future builds are about 10 minutes quicker (lots of dependencies!). Unfortunately, because setup() is called twice this no longer works:

  Running setup.py bdist_wheel for pysimplesoap
  Destination directory: /home/travis/wheelhouse
  Complete output from command /home/travis/virtualenv/python2.7.9/bin/python -c "import setuptools;__file__='/tmp/pip-build-v0_SSU/pysimplesoap/setup.py';exec(compile(open(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" bdist_wheel -d /home/travis/wheelhouse:

  Failed building wheel for pysimplesoap

I recreated this locally, and fixed it by only calling setup() once.

Another weird thing is that if you pip install pysimplesoap in an empty virtualenv and do pip freeze you get:

$ pip freeze
PySimpleSOAP==1.16
soap2py==1.16

That's because setup.py is executed by pip during the install. So pip downloads pysimplesoap but setup.py install will install pysimplesoap and soap2py from that .tar.gz. Of course, depending on which one you install, the other won't have the correct installed_files.txt in its egg-info, so pip uninstall gets weird:

$ pip uninstall soap2py
Uninstalling soap2py-1.16:
  lib/python2.7/site-packages/pysimplesoap
  lib/python2.7/site-packages/soap2py-1.16-py2.7.egg-info
Proceed (y/n)? n

$ pip uninstall pysimplesoap
Uninstalling PySimpleSOAP-1.16:
  lib/python2.7/site-packages/PySimpleSOAP-1.16-py2.7.egg-info
  lib/python2.7/site-packages/pysimplesoap/__init__.py
  lib/python2.7/site-packages/pysimplesoap/__init__.pyc
  lib/python2.7/site-packages/pysimplesoap/c14n.py
  lib/python2.7/site-packages/pysimplesoap/c14n.pyc
  <snip>
  lib/python2.7/site-packages/pysimplesoap/xmlsec.py
  lib/python2.7/site-packages/pysimplesoap/xmlsec.pyc
Proceed (y/n)? n

And if you uninstall one of these it will leave the egg-info directory for the other.

And if someone else then installs your requirements.txt that you made with pip freeze then pip will install pysimplesoap which will install both, then soap2py which will install both. Fun times!

There are a couple of alternatives you could try:

• Dummy project for the old name that just depends on the new name and has no other code, with a README.rst that gets shown on pypi to explain further.
• Dummy project for the old name that just explodes when setup.py is run (with a message saying what the new name is). Same README as above.

Coincidentally, I hit a package that does options 2 - try 'pip install py.test'. It just does:

import sys
from distutils.core import setup

if __name__ == "__main__":
    if "sdist" not in sys.argv[1:]:
        raise ValueError("please use 'pytest' pypi package instead of 'py.test'")
    setup(
        name="py.test",
        version="0.0",
        description="please use 'pytest' for installation",
    )

Has this ever been resolved? We are running into the same issues.

[Jc2k]

I'm still hoping for a fix too..

copying build/lib.linux-x86_64-2.7/pysimplesoap/helpers.py -> build/bdist.linux-x86_64/wheel/pysimplesoap
error: [Errno 2] No such file or directory: 'build/bdist.linux-x86_64/wheel/pysimplesoap/helpers.py'

I have been facing the same issue. I have deleted both pysimplesoap and soap2py and ran the execution. It is still prompting me with the same error.
