I failed to find any mention of this CHANGES.txt on that branch.

Thanks for the catch.  This was indeed a fix for a problem I uncovered
while ensuring that the Python and C implementations passed the same test
suite.  I have update the 'CHANGES.txt` file on the branch to indicate
the fix.

I still use buildout for complicated "application" installs, but have grown
to dislike it for testing "library" code.

They both pass the same suite of tests.  I can't guarantee 100% covereage
of the C code, but given that it passes the same tests, I'm satisfied.

> Question: does 'bin/python setup.py test' work?

Yes.  I consider that a necessary-but-not-sufficient minium for any library.

You can bootstrap and run the buildout and then run 'bin/test'.

Is that different from 'python setup.py develop'?  I've never seen 'dev'

Ooh, and I also see a tox.ini on that branch!  That's extremely welcome!

(Lately when I had to make some changes to zope.* packages I've been
kind of annoyed about the non-straightforwardness of testing all
supported Python versions.  I briefly tried tox, but didn't want to
spend hours figuring out how to make it play nice with buildout.)

Question: does the 100% coverage number mean both C code *and* Python
fallbacks are tested now?

Question: does 'bin/python setup.py test' work?

It seems to be becoming a sort of a universal standard for "run all the
tests of this Python package please", and is usually not that difficult
to hook up.  (If not, I may volunteer to hook it up.)

Question: can we still use zope.testrunner?

I like some of zope.testrunner's features a lot (like colorization, test
filtering options explicitly by module and by test name).  (I may also
volunteer to hook this up, if it's not hooked up.)

The 'docs' and 'dev' aliases are defined in setup.cfg::

 $ tail -n -3 setup.cfg
 [aliases]
 dev = develop easy_install zope.interface[testing]
 docs = easy_install zope.interface[docs]

and their extras_require in setup.py::

 $ egrep -B 2 "(testing_extras|'docs')" setup.py
 features = {'codeoptimization': codeoptimization}
 tests_require = ['zope.event']
 testing_extras = tests_require + ['nose', 'coverage']
 --
 tests_require = tests_require,
 install_requires = ['setuptools'],
 extras_require={'docs': ['Sphinx'],

I haven't had time yet to review this in detail, but this is most
definitely the right direction: separate tests from documentation, make
the tests expressive and the documentation clear. Wonderful!

Since I've thinking along these lines recently ("why do I need buildout
if all I want is a testrunner?"), I'm curious as to how this works,
especially
- Where does bin/nosetests come from?
- Where does "setup.py docs" come from?
