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

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
