GitPython : git push - set upstream

Question

Im using GitPython to clone a master branch and do a checkout of a feature branch, I do my local updates, commit and push back to git. The code snippet looks like below,

Note : my branch name is feature/pythontest

def git_clone():
    repo = Repo.clone_from(<git-repo>, <local-repo>)
    repo.git.checkout("-b", "feature/pythontest")
    # I have done with file updates 
    repo.git.add(update=True)
    repo.index.commit("commit")
    origin = repo.remote(name="origin")
    origin.push()

When I execute the script, I get the below error,

To push the current branch and set the remote as upstream, use
git push --set-upstream origin feature/pythontest

Answer 1

For pushing new branches you need to run git push --set-upstream origin branch_name you can read on --set-upstream in git documentation https://git-scm.com/docs/git-push This should do the work for gitpython:

def git_clone():
    branch_name = "feature/pythontest"
    repo = Repo.clone_from(<git-repo>, <local-repo>)
    repo.git.checkout("-b", branch_name)
    repo.git.add(repo.working_dir)
    commit_output = repo.git.commit(m="Commit msg")
    push_output = repo.git.push('--set-upstream', repo.remote().name, branch_name)

Hope this helps!

origin.push() doesn't know how to match the local branch to the one in the origin, so you need to specify it through refspec:

origin.push(refspec="master:origin")

master is your local branch and origin the target.

You can find more details here in the fetch definition.

I think you'd normally want refspec="master:master" if you've got a local master branch and you want it to track the master branch on the remote called 'origin'. (when I did master:origin I ended up with my 'origin' remote having a branch also called 'origin' which was tracked by my local branch called 'master') – Burp
