Git rebase is a bit different from other types. In the diagram above, the merge commit (X) is created by integrating the source and the target branch, where K and E are the parents of the merge commit. This type of merge will prompt Git merge conflict if the source branch is in dispute with the target branch. The changes are blended after the last common commit in both branches. It creates a new commit on a target branch by integrating changes in both the source and target branch. No-fast-forward MergeĪ no-fast-forward merge is also called a three-way or true merge. Fast-forward does not raise merge conflict issues as Git will not apply it if the head of the target branch is missing in the source branch.

For example, it is used to update the local branch from a remote server using the pull command. Fast-forward Mergeīy default, Git merge uses fast-forward to integrate missing commits into the target branch. Git rebase is another type of merge that resequences the commit history of the target branch. If the head of the target branch exists in the source branch, then by default, the merge type will be a fast-forward merge and if it is missing, then a no-fast-forward merge. Furthermore, Git merge performs either a fast-forward or a no-fast-forward merge. Git merge and rebase are the two ways to integrate commits from the target branch to the source branch.
In this case, the conflict has not been automatically resolved rather the developer has to make changes manually or use tools to resolve the conflict. Git will mark these changes and stop the merging process.

However, from time to time conflicts surface where two people have changed the same line of code or removed critical files that another developer was working on. The `git merge` command's primary job is to combine two branches and automatically resolve the conflicts. Merging these branches will prompt a merge conflict issue and halt the process. While abid is making changes, the original main branch is also being modified to “HELLO, DOG!”. The username abid forks the main branch, and changes the text to “HELLO, CAT!”. The main branch has a file containing the text “HELLO, WORLD!”. The diagram above gives the perfect example of how a typical Git merge conflict occurs. Sometimes multiple developers are working on the same line of code, and when they try to merge the changes, conflicts arise. This type of teamwork is highly productive and effective in finding bugs. Developers usually work on isolated branches, and when they are finished, they merge the changes with the main branch. Git version control system is all about working as a team and contributing to projects.
I think 3-way diff is quite useful and especially with distributed version control systems like git or mercurial it's needed more and more. Imagine using it to compare visually the same file across multiple repositories that might have diverged. Then, using those little arrows in the graphical diff I could click to "Insert from left", "Insert from right" or just "Delete" and reach the final text file I want.īesides merge, a 3-way Tools->Diff would also be handy. The tool should help me see conflicts in the same way 2-way diff helps me see changes. What I *should* see instead of a 2-way diff is a 3-way diff showing me the base file too and allowing me to keep changes from my side or from the other side. (Separate note: that window should be a graphical diff window. If I right-click then Mercurial->Resolve conflicts I'm presented with an ugly 2 way diff and a output window. This is a really bad way to visualize what changed. Locally I get a red conflict file which has some ">". >There are conflict/locally modified/new file(s) that will be overridden by Pull.\nDo you still want to perform the Pull? Right now, if I have modified a file locally and it's also been modified in the meantime in the mercurial repository and I do a pull the IDE presents me with: Well, first off, 3-way diff is nice when merging with a VCS.
