Features/walk support filter files?

[suziwen]

is repo walk support filter by files

No, since http://libgit2.github.com/libgit2/#HEAD/group/revwalk does not support it either and there is no high level api for pygit2 at the moment. You could try something like the following (initial commit is missing here):

def walk_for_files(repo, file_name):
    walker = repo.walk(repo.head.hex, pygit2.GIT_SORT_TOPOLOGICAL)
    c0 = walker.next()
    for c1 in walker:
        files_in_diff = ((x.old_file_path, x.new_file_path) for x in c1.tree.diff(c0.tree))
        if file_name in itertools.chain(*files_in_diff):
            yield c0
        c0 = c1

I implemented this once:

Probably it would be simpler today, since the API has been improved since.
