To stay in sync with the changes of the base branch, it’s just a matter of performing the rebase step with the up-to-date base branch. Until now, we have only interacted with `master` as our base branch. For now, this operation just prevents having a single merge commit with all the changes in it, and it’s still a single operation that happens at the last step of your contribution (i.e., when you want to share your work). As explained before, the two operations are not performed on the same branch: `rebase` is used on the feature branch whereas `merge` is performed of the base branch. You can simulate what happens when you click on the “Rebase and merge” (when there’s no conflict) by performing the following commands:īy doing so, you finally end up with a “linear history”:Īs you see, rebasing is not a substitution for the merging step. Before the final merge, we were in this situation: Hence rebase is not used to replace the merge, but it completes it.Ĭonsider the previous example. It is very important to observe that those two operations are performed in order, and that the rebase is not a substitution of the merge. It lets you perform a single rebase operation of your Pull Request commits on top of your base branch and then perform a merge. Also available for other repository managers such as GitLab, it’s the “rebase front door”. In September 2016, GitHub introduced a new way to merge pull requests: the “Rebase and merge” button. Let’s see how rebasing may help you address all those issues. Having a single merge commit containing all the changes to all your files probably isn’t what you want to expose in the end. Lastly - and this one may be a bit more subjective - you probably kept a logical breakdown between the commits of your branch. Secondly, the history may become too complex to understand once all your coworkers have merged their own branches to the base branch. This may not be an issue, but sometimes you would have really appreciated including that specific fix that your team merged, or getting rid of that huge dependency that slows you down every time you compile. First of all, if you’re working on your branch long enough, you may end up out-of-sync with the base branch for days or weeks. However, a few things are also a bit off here. Since the critical part where Git combines (or merges) your changes with the ones from the base branch only happens once, you will only need to deal with eventual conflicts once - at the merge step. There’s nothing wrong with this workflow in particular, you don’t have to bother about what your coworkers are doing so you can focus on your own work. Your pull request finally gets accepted and is merged into the base branch (C10)Īnd from there, your history becomes a bit more complex:.Meanwhile, other commits are merged to the base branch (C8 and C9).You push your updated feature branch to the centralized shared repo (C6 and C7 on the following schema).You make some changes and commit the fixes locally.
#Rebase to master git code
Merging branch is the most common way to integrate changes between two Git branches. First, as a way to integrate and exchange your work between two branches (like `merge` does), but also as a history rewriting tool. Confused? Don’t worry! This blog post is about different uses of `rebase`. Truth is, it’s more than that - `rebase` is a completely different set of tools that intersect with the goals achieved by `merge`. Git `rebase` is one of those commands that you may have heard of as a substitute for `merge`.
