I am trying to streamline some cherry-picking for gitlab workflows.

The principle is simple:

1. Create a merge-request and label it with a specific label that marks it to be backported (cherry picked)
2. Run a script that can create the necassary cherry-pick command

Now, I can rather simple get to the point where I have the source branch and target branch as objects in the API workflow:

# def get_project(project_id) -> Projectmr=project.mergerequests.get(id)project=get_project(project_id)source=get_project(mr.source_project_id,mr.manager.gitlab).branches.get(mr.source_branch)target=project.branches.get(mr.target_branch)

Generally these two originates from different sources, i.e.target.web_url != source.web_url.

I tried:

mb=project.repository_merge_base([target.commit["web_url"],source.commit["web_url"]])

to no avail (not that i fully expected this to work)...

So basically, how can I usegitlab to extract the merge-base between the two branches? Or, can I retrieve the commits that will be added (or has been added) totarget so I can create the necessary cherry-picks?

The merge-request can either be merged, or not merged, both cases are interesting!
