Cannot bind new attribute to git.objects.commit.Commit

I am trying to add an attribute to a git.objects.commit.Commit object that I obtained from a repo.iter_commits call,

    commits = repo.iter_commits(args.from_commit_ref + ".." + args.to_commit_ref)
    for commit in commits:
        setattr(commit, "href", "<somestring>"))

and I'm getting this error:

        setattr(commit, "href", os.path.join(diffhtmlpath, commit.binsha + ".html"))
AttributeError: 'Commit' object has no attribute 'href'

I understand these objects are wrappers, but can you provide some more info on whether what I'm trying to do is possible? I am trying to reuse these commit objects for a later purpose by inserting info in them. If this is not possible, I will have to make copies of the pertinent commit info I need into new objects and use those. I thought I'd check here is the former was possible using GitPython primitives.

Thanks.

Sorry for the late response. I believe the issue stems for __slots__ being used in most objects whenever possible, which means these objects don't actually have a dict for storing properties. Instead, they are stored in a more efficient data structure, saving memory at the expense of flexibility.

To workaround that, one could store the commit in your own object, and attach any attribute you want to that. Alternatively, one could map additional data to each commit, using a separate dictionary, depending on the actual requirements.

Please note that even though I am closing this issue, you are welcome to keep posting comments or follow-up questions.
