Rebase onto develop8/31/2023 ![]() ![]() Maybe there was a specific commit in the main branch, which fixed your bug but you aren’t quite ready to deal with any merge conflicts that might arise from pulling in commits past that point. The -onto flag can be used for any scenario in which you might say to yourself, “I need to rebase my branch, but I need to be more specific about what commit I want to rebase from.” In the next section, you will learn about some of these scenarios. What if you don’t want to include all of the commits in a certain branch? What if you don’t want to include all of the commits in your working branch? Pretty great, eh? But admittedly, as useful as this is, it is a pretty blunt instrument. Ask my coworkers why I might include this scenario here.Īgain, running git rebase main from the new-feature branch would set things right. In this case, you would not be able to merge the new-feature branch into main without also merging the first two commits to the feature branch. Or maybe you have been in this scenario at some point (I know I have), where you created a new branch while working on another unrelated feature but weren’t paying attention to the branch you were on previously. Here you can see that all of the most recent updates to the main branch are now available to you in your feature branch. This would result in the following scenario: In any case, if you want to move your branch to the head of the main branch, from your working branch you would run: git rebase main Maybe there is a bug fix that you need to build your feature, or another feature was added that will make the implementation of your feature better somehow. Let’s say you want to take advantage of some of those commits in the main branch. You have a few commits on to your branch, and, similarly, the main branch has also had a few commits merged in. Here you have a main branch, and your current working “feature” branch. If you are unfamiliar with git rebase, essentially what it does is allow you to say, “Move the start of my branch to the head of another branch.” Below is an example. It will walk through some of the operation of this command and flag, and give some visual examples, as well as code, to help clarify things as you proceed. ![]() This guide will go over some of the scenarios in which you may want to try to use git rebase -onto. And like any tool, you should be familiar with its operation. ![]() The command git rebase -onto is certainly not powerful enough to fix every scenario that can arise when teams start branching and merging at scale, but it is a powerful tool to have in your toolbox. But what happens when things don’t go exactly as planned? While the specific steps in this process will vary from team to team, this is, essentially, the flow when everything is going smoothly. If you use git on a regular basis, no doubt you are familiar with the standard flow of things: create and check out a new feature branch, build your feature, commit, and eventually merge it into the deployable branch.
