You can also create a branch starting from a previous commit in a branch's history. ![]() You can then work on this new branch in isolation from changes that other people are making to the repository. Typically, you might create a branch from the default branch of your repository. You always create a branch from an existing branch. For example, you could use a branch to develop a new feature or fix a bug. ![]() Branches isolate your development work from other branches in the repository. There is a lot more to learn about git rebase.You can use branches to safely experiment with changes to your project. In this article, you learned about merge commits and how you can avoid them when syncing your fork in Git using git rebase. The pull command will be: $ git pull -rebase upstream master You can skip the git fetch step by using git pull which is git fetch + git merge but with the -rebase flag to override the git merge. You may need to force the push with “ -force.” $ git push origin master -force Then finally, push the updates to your remote fork. Next, you rewrite your fork’s master with the upstream’s master using git rebase. In this step, you fetch all the branches of the remote upstream with: $ git fetch upstream In the above, upstream refers to the original repository from which you created the fork. If you run $ git remote -v, you will see the following: origin (fetch) One for your fork and one for the original codebase. To avoid merge commits, you need to rebase the changes from the original remote codebase in your local fork before pushing them to your remote fork by following the steps below.Ĭreate a link with the original remote repository to track and get the changes from the codebase with the command below: $ git remote add upstream Īfter running the above command, you will now have two remotes. How to avoid merge commits when syncing a fork in Git. Next, you will learn how to avoid it when syncing your fork with an original codebase. Here is the link to the merge commit to the image. The annotated section in the image above shows a merge commit of two parent commits. This merge commit can cause conflicts and mess up a project’s Git history if present in a merged PR. When you create a merge commit, Git automatically merges the histories of two separate commits. But there is one thing unique about a merge commit: it has at least two parent commits. ![]() how to avoid them with git rebase when syncing a fork with an original codebase.Ī merge commit is just like any other commit, it is the state of a repository at a point in time plus the history it evolved from.But with a PR open, syncing your fork that way will introduce an unwanted merge commit to your PR. To sync your fork with the original codebase, ideally, you would use the web UI provided by your Git hosting service or run a git fetch and git merge in your terminal, as indicated in this Github tutorial. After you create a PR, there are chances that during its review process, commits will be made to the original codebase, which will require you to sync your fork. ![]() To propose changes, you open up a Pull Request (PR). Whenever you work on open source projects, you usually maintain your copy (a fork) of the original codebase.
