Thank you.
Can you please add/update the test suite to verify it is working ?

The tests are passing. However, I had to temporarily add

   @classmethod   def setup_class(cls):           cls.setUpAll()

to the TestDiff class. Otherwise I get an
"AttributeError: 'TestDiff' object has no attribute 'rorepo'" for every test
Any clues on that? What version of nose are you using? I'm using nose 1.1.2 atm.

I use nosetests version 1.0.0, but I would wonder why they change the API in such a manner that causes tests to break.
Can you also add a diff output containing a rename, and add it to the test suite ?

I have addedhttps://github.com/P2000/GitPython/blob/p2000/git/test/fixtures/diff_rename_raw
andhttps://github.com/P2000/GitPython/blob/p2000/git/test/fixtures/diff_rename
has been already there. Both are in use in git.test.test_diff.TestDiff

Not sure what you mean otherwise?

The nosetest incompatibilites are probably based on different python versions then.
I have been using cpython 2.7 before and now tried with 2.6.
Some tests are still failing but most work now.
What python version are you using?

"$ nosetests":http://sprunge.us/WZYB
"$ nosetests git/test/test_diff.py":http://sprunge.us/GcSf

I am using python 2.4 to 2.6, these are the versions I am testing with at least.
Besides that, you can ignore the errors I believe, as they relate to a package you have not installed. Of course, these tests should detect that and be skipped automatically, but its not related to this issue.

The master branch is heavily WIP, even though its stale for a while now. Branch 0.3 is the one most people would be using, I wouldn't think that master is in any way ready for production, at least I am not using it in production either.

As there already seem to be rename tests, it should be okay to just merge it in.
Thanks for your effort !

thanks for merging!
