git merge
The steps below assume you have two branches target-branch and source-branch, and the directory dir-to-merge that you want to merge is in the source-branch. You can cancel an unfinished rebase operation or resume an interrupted rebase by selecting the Abort or Continue actions respectively from the top of the Git Branches popup. For example, a fast forward merge of some-feature into master would look something like the following: However, a fast-forward merge is not possible if the branches have diverged. The simple way, to actually merge specific files from two branches, not just replace specific files with ones from another branch. No Commit Do not automatically create a commit after merge.
Merge changes from one branch to another (Git)
The Golden Rule of Rebasing Once you understand what rebasing is, the most important thing to learn is when not to do it. Then, you run a normal git commit to generate the merge commit. It is also helpful—if you run into situations like this a lot—to have alongside your current one that always have the master branch checked out. You'll then have to decide yourself which content you want. This solution does that, but may be tedious if there are many files. The only way to synchronize the two master branches is to merge them back together, resulting in an extra merge commit and two sets of commits that contain the same changes the original ones, and the ones from your rebased branch. This can happen when collaborating on the same feature with another developer and you need to incorporate their changes into your repository.
Merging
Note that merge conflicts will only occur in the event of a 3-way merge. From Git points of view, nothing changes in master branch, so simply moves master pointer is the easiest and fastest way to merge. Slashes don't need to be escaped. This use of git rebase is similar to a local cleanup and can be performed simultaneously , but in the process it incorporates those upstream commits from master. Abandon the exp branches for now and use two additional local repositories for experimentation.
Git basics: how to merge changes from a different fork into your own branch
This prevents superfluous merge commits from cluttering up the project history. At this point though, there are no changes to commit, so get the files from the other revisions, next. Note that all of the commands presented below merge into the current branch. Also assume you have other directories like dir-to-retain in the target that you don't want to change and retain history. If you already have a local branch with the changes you only need to do steps 2 and 5-7. If you haven't added the changed files to the index, yet, then you may be able to just checkout the other branch. Perhaps it's easier to understand the stash approach, or it may just be that it's not obvious enough that checkout is 'safe' in this use case.
Git basics: how to merge changes from a different fork into your own branch
This results in a forked history, which should be familiar to anyone who has used Git as a collaboration tool. The only thing other developers will see is your finished product, which should be a clean, easy-to-follow feature branch history. The current branch will be updated to reflect the merge, but the target branch will be completely unaffected. The chosen hunks are then applied in reverse to the working tree and if a was specified, the index. How it works Git merge will combine multiple sequences of commits into one unified history. This comes up enough in my workflow that I've almost tried to write a new git command for it. But, you can force the push to go through by passing the --force flag, like so: Be very careful with this command! No Fast Forward Generate a merge commit even if the merge resolved as a fast-forward.

Log view will not show merge line between two branch. I wasn't able to figure out how to use this method to get in-file diff information maybe it still will for extreme differences. By default, the git pull command performs a merge, but you can force it to integrate the remote branch with a rebase by passing it the --rebase option. The first step in any workflow that leverages git rebase is to create a dedicated branch for each feature. I see that has the same profile as yours, are you using two accounts? The --no-commit option will stage the files that have been merged by Git without actually committing them.
Merging vs. Rebasing
While working on a branch named login, based on the master branch, one of your team members pushed some changes to master. For details on how to skip or squash commit during a rebase, refer to. Also, the deletion was an honest mistake, how could you expect anyone to tell that you were using two different accounts? If you only need to merge a particular directory and leave everything else intact and yet preserve history, you could possibly try this. Messages Populate the log message with one-line descriptions from the actual commits that are being merged. Incorporating Upstream Changes Into a Feature In the Conceptual Overview section, we saw how a feature branch can incorporate upstream changes from master using either git merge or git rebase. Use the information in the Commit Details area if necessary. First, it eliminates the unnecessary merge commits required by git merge.
Merging Changes
There is no git merge alternative for cleaning up local commits with an interactive rebase. Depending on how you want to merge files, there are four cases: 1 You want a true merge. Once the fetch is completed ensure the master branch has the latest updates by executing git pull. Force-Pushing If you try to push the rebased master branch back to a remote repository, Git will prevent you from doing so because it conflicts with the remote master branch. Our first example demonstrates a fast-forward merge. Back to home of Team Explorer and select Settings.

If you want to review the changes or even modify the code before committing it to the target branch, you can do so in the difference viewer available from this dialog. This may be useful, for example, if you are working in a feature branch and want to integrate a hotfix from master that was committed after the two branches have diverged. In our case we will execute git checkout master. It's useful you have radically different file changes between versions--in my case, changing an app from Rails 2 to Rails 3. Needless to say, this is a very confusing situation.
Git: merging specific files from another branch » Hay Kranen
The nomenclature comes from the fact that Git uses three commits to generate the merge commit: the two branch tips and their common ancestor. When such a situation occurs, it stops right before the merge commit so that you can resolve the conflicts manually. Hint: It also works without -- like seen in the linked post. Just change to software of your choice if needed. What this means is that changes in the master and branchX for all those three files have been combined together without any conflicts. By periodically performing an interactive rebase, you can make sure each commit in your feature is focused and meaningful.
