However, because this operation changes git history, git will reject the push by default. Now we can push these changes to the remote repository. I wish I could say I've never had to run that command. It's notable that if you had trouble with the merge conflict, you can run git rebase -abort to abort the rebase and get back to where you were before you started the rebase. and then run git rebase -continue and git will apply the rest of our commits. With that fixed, we can now add everything with git add. Then we'll remove these marks that get added to our code for the conflict. We'll simply remove the original export and add our function to the list here. It looks like a new method was added and the format of the export was changed, possibly to avoid conflicts like this in the future. There are some UI programs you can use that help manage merge conflicts which can be helpful, but often your merge conflicts are simple enough that we can open our editor and fix them ourselves. We can run git diff to see what files are having trouble. Now we see that while git was applying our first command, there was a merge conflict and git is waiting for us to fix the problem. That's essentially what's happening with git rebase. Even though those commits on Master happened after our commence, what's essentially happening is we apply those commits from Master first, and then we apply each one of our commits on top of that. You can think of this as if we were just doing all of our changes today, and we were getting a brand new fresh copy of Master and then applying our commits onto what that fresh new copy of Master is. Then we'll tell git that we want to replay our commits onto what exists on Master in the upstream remote. To do this, we'll enter the command git fetch upstream. First, we'll need to update our machine's knowledge of the remote we call the upstream. Then we'll have to manually merge our changes with the latest version of Master. Because of the way we set up our project earlier in the series, starting the rebase will be a matter of a few simple commands. Even in cases where there is no merge conflict, it can be good to update the pull request with the latest changes by doing what's called a git rebase because it makes managing the git history a little nicer for the project maintainer. In this scenario GitHub is unable to automatically merge the pull request and we need to manage this ourselves. When this happens, if the changes on the remote repository conflict with our own changes, we get what's called a merge conflict.

I hope this post will help you not only get through this situation but also understand how git merge and git rebase differ and where to use them. You don't only solve that problem but also get to understand the usage of tech involved in the process. Learning through use-cases is the best way to master anything. A perfect scenario is when you haven't shared your work with anyone. Otherwise, you might get an error.īecause of the fact that git rebase copies commits and changes history, don't use it when you shared those commits with the team. So, not only we created copies of C, and D commits, we also put E, and F at their original positions: git history is changed. You need to manually link your cloned repo with upstream.įor the sake of convenience let's assume two repos: So let's get started!īelow is the visualization of the current scenario.įor those who are not familiar with the concepts of upstream, it's not the local or the forked one, it points to the original repository on GitHub. To all those struggling, this guide will help you handle such a situation and help you understand the underlying concepts of git as well. What to do now? You might have struggled with this scenario at some time in your career. Time to create a pull request - but the original master branch has more commits now.Let's consider a scenario where you are contributing to an open-source project.
