Pushing Changes Back Upstream with Subtree Split
Learn how to extract changes made inside a subtree and push them back to the original upstream repository using git subtree split and push.
Two-Way Subtree Workflows
Subtree is not just for pulling code in. One of its strengths is the ability to contribute changes back to the original project. This makes subtree a genuine two-way integration tool.
The key command is git subtree push, powered internally by git subtree split.
What 'split' Does
git subtree split walks your history and produces a synthetic branch containing only the commits that touched the subtree's prefix, rewritten as if that folder were the repo root.
This is what makes the changes mergeable back upstream.
