#Merge branch into master git code
To push the branch code to the remote repository, set the upstream branch using git push. When you create a branch in your local repository, the remote repository isn’t aware of it yet. Git merge feature Merging Branches to Remote Repository Note that this will be a fast-forward merge. In this example, we are merging the feature branch into the main branch. Then, use git merge and specify the name of the other branch that you want to bring into this one. To merge branches locally, first, we have to switch to the branch you want to merge into using the git checkout command(suppose you want to merge a feature branch into the master branch then you have to switch to the master branch). Git log -oneline -all -graph Merging Branches in a Local Repository Based on these snapshots git will create a new commit by combining the changes. Tip of the future branch which means the last commit happened in the future branch.īefore merging the changes git looks at the 3 snapshots which are before snapshots, after snapshots, and the base file or the common ancestor with which these two files will be compared.Tip of the master branch which means the last commit happened in the master branch.First Git will try to find out the commit from where the branches have diverged.Now We will Understand how this merge happens Step by Step. This means that there has been no commit to the master branch since your feature branch diverted at the point of merge.Įxample: A fast-forward merge of some-feature into the main would look something like the following: To do a fast-forward merge, make sure there is a linear path from the branch you are diverting from to the branch you are merging.
Let’s try to understand both fast-forward and three-way mergers based on the branches and commit history by using the following diagram. When we start merging branches, Git will take the commit history into account and perform a fast-forward or three-way merge.
Merging takes the branch changes and integrates them into the main branch.
Git Merge TypesĪfter you finish making changes to a branch, it’s time to merge those changes into the main branch. This is called a version control conflict, and Git will need you to resolve it before continuing. However, if Git encounters data that has been changed in both histories, it won’t be able to combine them automatically. When creating a merge commit, Git will automatically try to merge the separate histories. Merge commits are different from other types of commits because they have two parent commits. If you have a new branch feature that is based on the main branch, and you want to merge this feature branch into the main branch, here’s what you need to do: Once Git finds a common base commit it will create a new “merge commit” that combines the changes of each queued merge commit sequence. When using git merge, you specify two commit pointers, usually, the branch tips and Git will find a common base commit between them. The examples in this document will focus on this branch merging pattern. In most cases, git merge is used to combine two branches. Git merge is a powerful tool that can combine multiple sequences of commits into one unified history. The third line in the image below shows that the merge was done using a “fast-forward” technique employed by git.īefore understanding Fast-Forward Merge In Git we have to understand how the git merge works. If you follow the same steps as above, you will be able to successfully merge changes into your local repository.
