I'm using the recommended GitPython module, but I cannot figure out how to construct the following command:
git diff --name-status ec04352 b945e6c
I would like to get information about all modified files between two commits, and this command does exactly what I want to do. Could you comment on it?
This is one way to do it:
import git
repo = git.Repo('path/to/your/repo')
print repo.git.diff('ec04352', 'b945e6c', **{'name-status': True})
It is, however, going through the backdoor.
You should be able to do something like this:
a = repo.commit('ec04352')
b = repo.commit('b945e6c')
diffs = a.diff(b)
>>> a
<git.Commit "ec04352">
>>> b
<git.Commit "b945e6c">
>>> print diffs[0]

You'll need to play with the Diff object to figure out the difference.
See Obtaining Diff Information in the GitPython manual for a few example on how to get the diff information between two commits.
hcommit = repo.head.commit
idiff = hcommit.diff() # diff tree against index
tdiff = hcommit.diff('HEAD~1') # diff tree against previous tree
wdiff = hcommit.diff(None) # diff tree against working tree
These commands return a DiffIndex, which contain iter_change_type which you can call with each of the four different change types ('A', 'D', 'R', 'M') to get the paths that have been changed (added, deleted, renamed, modified).
