Example sentences

    The common ancestor provides the starting point for identifying what changed on each side.

  2. When the diff looked too large, we checked the merge base and found the branch had diverged from main last month.

    In this sentence, merge base helps diagnose why the comparison contains many changes the team did not expect to see.

  • merge-base commit
  • common merge base
  • branchA separate line of development in a repository, where you can work on changes without affecting the main code until you are ready to merge.
