Advanced Git Workflows

Git gives you commits, branches, tags, and remotes. A workflow turns those parts into a collaboration policy.

The policy answers practical questions. Where does new work begin? When can a branch enter the shared history? Who integrates it? Which checks must pass? May you rewrite it? How do you move an urgent fix without moving unrelated work?

There is no single advanced workflow that fits every team. Git supports a centralized shared repository, an integration-manager model, and more distributed arrangements. You can also combine parts of those models. The useful choice is the smallest policy that matches your release risk, team shape, and integration frequency.

Think in commits and references

A commit records a snapshot and points to its parent commit or commits. Those parent links form a directed history. A branch is a movable reference to one commit. A tag normally names a specific point.

This model matters because most advanced operations change either the graph or a reference:

• A merge joins development histories. A true merge commit has more than one parent.
• A rebase reapplies commits on a new base. It creates new commits, even when the resulting files look the same.
• A cherry-pick applies the change introduced by an existing commit and records a new commit.
• A fast-forward moves a branch reference because the current tip is already an ancestor of the incoming tip.

Treat commit identity as immutable. If you rewrite a commit, you create a replacement with a different identity.
