Second, collect all the commits between the ancestor commit and the current commit. This can be thought of as a two-step process: first, find the common ancestor of and the current commit call this the ancestor commit. Identifies each commit that is an ancestor of the current commit but not of.When ran, Git performs the following steps: The Git command above will rebase the current branch onto, which can be any kind of commit reference (an ID, a branch name, a tag, or a relative reference to HEAD). Rebasing loses the context provided by a merge commit so unable to see when upstream changes were incorporated into the feature. If you don’t follow the golden rule of rebasing, never use it on public branches, re-writing project history can be catastrophic for collaboration. The two-trade offs are safety & traceability. You’ll be able to follow the top of feature all the way to the beginning of the project with git log, git bisect and gitk. It eliminates unnecessary merge commits required by git merge and results in a perfectly linear project history - shown in the diagram above. The major benefit to git rebasing is a much cleaner project history. Cleans intermediate commits by making them a single commit.Avoids merge commit “noise” in busy repos with busy branches.

Streamlines a potentially complex history.

* Brand new commit Benefits to Rebasing - two trade-offs. Let’s say you start working on a new feature in a dedicated branch, then another developer updates the master branch with new commits resulting in a forked history. There’s also a special kind of merge called fast-forward, done when a branch being merged is just a continuation of the branch you’re merging into-so the new commits are just pasted on top of the target branch (ie.

Merging adds a new commit to your history.

As a result, only the master branch is changed.

Merging takes the contents of the feature branch and integrates it with the master branch.

When you do rebase a feature branch onto master, you move the base of the feature branch to master branch’s ending point.The first thing to understand about git rebase is that it solves the same problem as git merge Both are designed to integrate changes from one branch into another - just in different ways. It’s very important to understand that even though the branch looks the same, it’s composed of entirely new commits. Git accomplishes this by creating new commits and applying them to the specified base. Rebasing changes the base of your branch from one commit to another making it appear as if you’d created your branch from a different commit. Git rebase is the process of moving or combining a sequence of commits to a new base commit.
