![]() ![]() The main benefit is a clean, readable git history. Rebase is often referred to as the “unsafe” method of merging branches. True, merge is the safer option- which is why it is used much more often. With rebase, your commits are sprinkled in to the commit history, like milk in tea, never to be retrieved (sorry, English major moment there).Ī side effect of this is changed commit hash names, which means if your branch was pushed to an origin site (like github), you will have to use the –f flag to force push it back up, because it looks like a brand new branch. This is nice, because if something goes terribly wrong during the merge, you can revert back to the previous state of your branch. When you merge a branch, your git history looks like this -> your commits + merged branch with all the things. If some of your commits were done before the commits in the branch you are rebasing onto, AND some were after them, you’ll have several “rounds” (a term I came up with, not official) of rebasing, during which, if there are merge conflicts, you’ll have the special privilege of multiple rounds of merge conflict resolution! And your git history will be rewritten completely, meaning you cannot get back to the state it was before rebasing, like when merging a branch directly. You essentially tell git that this branch is the template and you want to fill your commits in around the existing commits in this branch. What happens is you rebase “onto” the branch you want to catch up with. Rebase essentially rewrites your git history to put all the commits in their proper place in time. Without all the merge commits, your git history is much easier to read, and is a more accurate record of project progress. But it leaves behind a trace: “Branch so and so has been merged into branch Bob Loblaw.” And sometimes you need finer control over what is in your branch, you want to pull another feature into the branch you’re working on, or you’re just really anal about your git history. ![]() Git is an extremely sophisticated program that does some great parsing and does its best to combine unlike things into what you (usually) expect it would. Sometimes, it’s best to just merge and let git do its thing. The answer is kind of complicated and very dependent on style and sensibility. Rebase? Squash? WTF IS THAT!! Why can’t we just merge it? Now rebase and squash that thing and we can merge it in.” Beaming with pride, I messaged my team lead that I had finished the first task handed to me… And he responded “looks good. I hit save, go to my terminal, and type in my commit message. Let’s set the scene: there I am, agonizing over my keyboard, putting the final touches on my masterpiece of a first feature - am I being too dramatic?! ). When I started one of my first professional programming jobs, I was met with a surprise when I put in my first PR. That commit is pulled into your current branch. Git cherry-pick 0d1dsomehashthingycopiedfromgithistory We’re currently in our lovely co-worker’s branch. Whoo, we traveled through spacetime to an imaginary terminal. ![]() In our example, you would checkout to your feature branch. This basically lets you copy a specific commit and superglue it on the end of your current branch. Now you reach into your bag of git tricks, and pull out a cherry-pick. What’s that message back from git? Crap, you’re still on your co-workers branch? Type-itty type, you go back to the feature you were working on. ![]() Everything looks good you put a comment and a ship emoji on their PR in github and go on your merry way. So at some point in your day, you move from a branch that you’re working on to a teammate’s branch to look at the code they wrote. Say you’re working on a team and you do code review as a part of your process. You can do this for one commit, or a range of commits from a separate branch. What is cherry-pick:Ĭherry-pick essentially pulls changes from a different branch into the current branch you are on. *Photo Credit: The brilliant and hilarious XKCD: Git Cherry-Pickįirst things first, the cherry-pick command. ![]()
