List of branches a commit appears on

Question

Using the GitHub API (v3) I\'d like to figure out which branches a commit appears on. I didn\'t find a way to directly query this, either through repo commits or the commit

Answer 1

GitLab API

Following Ivan Zuzak's solution number 2, to know if a commit is on a branch:

Use GitLab's repository compare API, and compare from the branch, to the commit

GET /projects/:id/repository/compare?from=&to=

If the commits list is empty, then yes, the commit is on that branch.

In Python, using python-gitlab:

def is_commit_on_branch(project, commit, branch):
    c = project.repository_compare(branch, commit)
    return not c['commits']
