Git: Push shallow clone to a new remote without 'unshallow'?

Question

I made a shallow clone of a repository with git clone --depth=1. I made some changes... apparently without understanding the complications of shallow clones...

Answer 1

Why can't I push from a shallow clone? seems to have some additional commentary. In fact, look at this comment:

Update 2015: with Git 2.5+, you will even be able to fetch a single commit. See "Pull a specific commit from a remote git repository"

So perhaps you can't push, but from the other side, you can pull. Have you tried that?

Answer 2

I would do it as follows:

1. Create a new root branch:

   git checkout --orphan truncated_master
   

2. Populate its initial commit with the earliest available commit in your shallow repository:

   START_COMMIT=$(git rev-list master|tail -n 1)
   git checkout $START_COMMIT -- .
   git commit -m "Initial commit"
   

3. Copy all commits from master to the new branch:

   git cherry-pick $START_COMMIT..master
   

4. Push the new branch to the new remote:

   git push origin truncated_master:master
