This function was removed in python 3: http://docs.python.org/3.3/whatsnew/3.0.html#library-changes
I haven't noticed it until I test it on Windows, since I don't have git installed.
What's the alternative in python 3?

[jaimeMF]

I guess de29c41 fixes it.

This doesn't fix it, it merely hides it in a try/catch.
I can't find sys.exc_clear anywhere in the python 3 documentation, so it might as well be removed, in my opinion.

It doesn't seem there's an actual way around this. Back in 2011 fabioz/Pydev@ed35a22 did it by using hasattr(...) function.

It seems sys.exc_clear() was deleted cuz whatever data that function cleared is/should already be automatically cleared by the time you execute the function.
