In the command line, you can do this with the flag -no-ff, for no fast forward. Lastly, you can force Git to always create a merge commit, eventhough it is strictly, technically, not needed. So, it needs to be represented with a brand new commit, which is what you see at the top of your first example Git created what it calls a "merge commit" to represent the new state with the changes from each branch merged into a single state. The new content, after the merge, will neither be the last state of the first branch, nor will it be the state of the second branch. If it can't, you have a merge conflict, which is really not as bad as it sounds). It will need to figure out how to unify the changes from the two branches into a single state of the files under its control (let's assume, for now, it is always able to do that, which is not that far from the truth its quite good at it. Git can now no longer "cheat" by just moving branch-labels around. You made a commit on master, then did a git checkout develop, made a commit there, and then asked Git to merge master back into develop. Should each branch have extra commits, like in your first example right before merging master into develop, "something more complicated" is going on. Mission accomplished, changes that were only in develop before are now also in master. So, it will do a "fast forward" merge, by simply taking the master label and sticking it to the commit where develop is pointing. Git will look at the branches, and see that develop is just ahead of master by a few commits, but there's nothing more complicated going on than that. Let's say you want to merge the changes you made to develop into master, so you tell git: $ git checkout master When you ask Git to merge one branch into another, Git will go and figure out what it needs to do to get the difference between those branches into the target branch. Let's take your second example and imagine that your master and develop are where originally origin/master and origin/develop were: The real confusion starts when you start merging branches again, and this is largely due to a weird thing Git calls "fast forward merging", which it does by default. Only when you create a new commit while this new branch is checked out, will you see the new branch diverge from the other branch. When you create a new branch, all that happens is that Git creates a new label, pointing to the same commit you were on. (You might ask, how is this different from tags, then? A tag is stuck to the same commit, and will not get updates when you call git commit.) First, it's useful to understand that branches in Git are really just "labels" that are stuck to a particular commit, and that will be moved automatically when you commit to the the branch Git will create the new commit, with a new commit hash, and update the branch/label to point to the new commit. If you can merge, then you should use that instead of cherry picking.There's a few things going on here. The main reason is because it creates a duplicate commit with the same changes and you lose the ability to track the history of the original commit. Should I cherry pick merge commits?Ĭherry picking is commonly discouraged in developer community. When picking multiple commits you can run git cherry-pick –continue from the console. EDIT Edward noted that this is only true when you are cherry-pick ing a single commit. This means if you get any conflicts during cherry-pick ing you just need to commit after resolving them to finish the cherry-pick. How do you continue cherry-pick after resolving conflict? Make sure you are on the branch you want to apply the commit to.Do the changes you want according to modified files.Go to the branch which you want to change / revert some modified files.How do you revert a merge commit from a branch? Push and pull changes as often as you can.Do not beautify a code outside of your changes.Do not always put your changes at the end of a file.Whenever it is possible, use a new file in preference to an existing one.
