Description
GitPython seems to break on large repositories. I've hacked a bit of additional output into the assertion at https://github.com/gitpython-developers/GitPython/blob/master/git/remote.py#L576 :
# NOTE: We assume to fetch at least enough progress lines to allow matching each fetch head line with it.
assert len(fetch_info_lines) >= len(fetch_head_info), "%d <= %d - len(fetch_head_info) <= len(fetch_info_lines) : len(%s) <= len(%s)" % (
len(fetch_head_info),
len(fetch_info_lines),
fetch_head_info,
fetch_info_lines)
When I run git.Repo.clone_from() or .fetch(), it produces:
[DEBUG reconcile_git_repos.py:95 - clone_or_fetch() ] Fetching origin in /localfs/users/jantman/B-07815/storyville2.git

... and then an amazingly long line of output.
This appears to happen with very large repositories; I honestly can't tell if the issue here is commit messages or the repository size - the one I used for testing has (yeah..... :( ) 4,789 branches.
