Installing python-social-auth as a dependecie for mailman3 with buildout fails

[ziegenberg]

I tried to install Mailman 3 and its companions (Hyperkitty, Postorius) on a
Ubuntu 14.04.2 LTS using the mailman-bundler. I followed the docs:
http://mailman-bundler.readthedocs.org/en/latest/

It fails while trying to install 'python-social-aut':

(venv)mailman@jiffy02:~/mailman-bundler$ buildout
Getting distribution for 'python-social-auth>=0.2.3'.
No eggs found in
/tmp/easy_install-LK6bYy/python-social-auth-0.2.9/egg-dist-tmp-FzLeGP (setup
script problem?)
While:
Installing mailman-web.
Getting distribution for 'python-social-auth>=0.2.3'.
Error: Couldn't install: python-social-auth 0.2.9

I checked with the folks from mailman3 and they told me to file a bug here.

You can test the install with buildout by creating a file called "buidout.cfg" in a temporary directory with the following content:

[buildout]
parts = main
[main]
recipe = zc.recipe.egg
eggs = python-social-auth

And running the "buildout" command.

I created a new temporary user, build a virtual environment and tested python-social-auth with buildout in two different versions.

testing@jiffy02:~$ virtualenv venv
testing@jiffy02:~$ source venv/bin/activate
(venv) testing@jiffy02:~$ pip install zc.buildout
(venv) testing@jiffy02:~$ buildout

buildout.cfg (#1)

Same problem over here. I did a manual download of python-social 0.2.9, untar, python setup.py bdist_egg, unzip of that egg, and the mailman3 buildout continued without complaints.

(No idea what I did though, I never use buildout nor eggs.)

Apparently this change:

-python-openid>=2.2
+python3-openid>=3.0.1

I had to install the former to make things work. Installing the latter complained about py3-only stuff. (mailman setup scripts use py2).

[abompard]

OK I found the reason. In MANIFEST.in, the egg-info directory is ignored, and these files are necessary for easy_install to work. Buildout uses easy_install, thus triggers the error.
This can be easily reproduced with the command:

$ easy_install -md /tmp http://pypi.python.org/packages/source/p/python-social-auth/python-social-auth-0.2.10.tar.gz

The fix is as easy as:

diff --git a/MANIFEST.in b/MANIFEST.in

I'll send you a pull request ASAP.

Please, apply the patch from abompard and release a new version. Until that happens, I can only use the version 0.2.7
