Using the -ff-only option when you eventually merge guarantees that no changes have been pushed while you were doing your rebase. If someone pushes another commit to the collaboration branch while you’re running your unit and integrations tests, rebase again and re-run your tests. Lots of small rebases make conflicts less likely, and much easier to resolve if they do happen. Rebasing often – ideally, every time someone pushes a commit – ensures that your work always incorporates the latest changes. When rebasing, the merge is always going to be fast-forwarded. It eliminates the risk of merge conflicts when you finally merge two branches. Keeping your branch up to date with the collaboration branch achieves the following: Typically, this is done because you will eventually merge your feature branch with the upstream collaboration branch. The primary reason to rebase is to keep a feature branch up to date with an upstream collaboration branch. These are also the same set of commits that you would get from the git log -patch -reverse. The commits that are temporarily stored when rebasing are the same set of commits that are displayed when issuing the git log. Typically, your Git repository’s project leaders determine which method they prefer to use to combine changes between branches. B and its history, on the other hand, tell the story of how the project was made. M and its history record what everyone did – it’s a historical record of what work was done on the project. What’s different about the two commit histories is the information available in each. my-feature-branchī, in the rebase diagram and M, in the merge diagram, are both snapshots of approximately the same state. Merging your feature branch with the main branch can be accomplished with the following commands: git checkout mainĪfter running the git rebase main command, your local branch’s commit history resembles the following: A'-B'. This method updates your local feature branch with the latest changes pushed up to the collaboration branch by your teammates. Git Rebase: A Git rebase takes the commits made in your local branch and places them on top of the latest commits pulled down from the main branch.
Git rebase vs pull code#
This makes it difficult for anyone reviewing your code to figure out exactly what changes you made. If you continue to work on your feature branch, you eventually have to make another merge with main. This is considered a fast-forward merge because main is a direct ancestor of M. Once you’ve merged the two branches, you can either keep working on your branch, or merge it back into main. The M represents the merge commit that ties together the two branches. When merging two branches together using a merge commit, your local branch’s commit history resembles the following: A-B-M my-feature-branch Merging your feature branch with the main branch can be accomplished with the following commands: git checkout main This method creates a new commit that incorporates the changes from both branches. Git Merge: A Git merge allows you to merge your feature branch with the main collaboration branch.
Other repository collaborators have made changes to the main collaboration branch.The main branch is the base of your local my-feature-branch. You forked off of the main collaboration branch.You are working on a local feature branch named my-feature-branch.This section uses the scenario described below to explore the differences between Git’s rebase command versus Git’s merge command. This is an important detail to remember, especially when working with collaboration branches or branches that have already been accessed by other team members. Rebasing does not change the content of your commits, but it does change the commit hash that is used to track your changes. This method is a form of rewriting a branch’s commit history.
Git rebase vs pull series#
Rebasing takes a series of commits and reapplies them on top of another base commit.
