In Git, to "fast forward" means to update the HEAD pointer in such a way that its new value is a direct descendant of the prior value. In other words, the prior value is a parent, or grandparent, or grandgrandparent,... Fast forwarding is not possible when the new HEAD is in a diverged state relative to the stream you want to integrate.
What is the best git branch strategy?
- Of the three Git branch strategies we cover in this post, GitHub flow is the most simple.

How do I properly force a Git push?
edited Sep 18, 2019 by yeshwanth.intelli. For this, you need to use the following command. git push origin <your_branch_name> --force. Or if you have a specific repository you can use. git push <git-url> --force. This will delete your previous commit (s) and push your current one. --force is having a small flag -f you can use -f also.
How to move a branch forward in Git?
- Determine what work is unique to our branch (C2, C3, C4, C6, C7)
- Determine which are not merge commits (C2, C3, C4)
- Determine which have not been rewritten into the target branch (just C2 and C3, since C4 is the same patch as C4')
- Apply those commits to the top of teamone/master
Does Git push push to current branch?
In the current setting (i.e. push. default=matching ), git push without argument will push all branches that exist locally and remotely with the same name. This is usually appropriate when a developer pushes to his own public repository, but may be confusing if not dangerous when using a shared repository.
What are fast forward commits?
If Master has not diverged, instead of creating a new commit, git will just point master to the latest commit of the feature branch. This is a “fast forward.”
What does no fast forward mean in git?
Using the --no-ff parameter prevents the Git merge command from performing a fast-forward merge when Git detects that the current HEAD is an ancestor of the commit that you're trying to merge.
What is rebase and fast forward?
Rebase, fast-forward ( rebase + merge --ff-only) : Commits from the source branch onto the target branch, creating a new non-merge commit for each incoming commit. Fast-forwards the target branch with the resulting commits. The PR branch is not modified by this operation.
Does git merge fast forward by default?
By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
Does a fast forward merge create a commit?
Fast-forward merge It will take the commits from the branch being merged and place them at the tip of the branch you're merging into. This creates a linear history, which is also the main advantage of using fast-forward merge.
Should I squash and merge?
As a general rule, when merging a pull request from a feature branch with a messy commit history, you should squash your commits. There are exceptions, but in most cases, squashing results in a cleaner Git history that's easier for the team to read.
What is Fast forward push?
Fast forward is simply forwarding the current commit ref of the branch. When our changes are pushed Git automatically searches for a linear path from the current ref to the target commit ref.
What is rebase in git?
What is git rebase? Rebasing is the process of moving or combining a sequence of commits to a new base commit. Rebasing is most useful and easily visualized in the context of a feature branching workflow.
What is git rebase vs merge?
Git merge is a command that allows you to merge branches from Git. Git rebase is a command that allows developers to integrate changes from one branch to another. In Git Merge logs will be showing the complete history of the merging of commits.

Why is it called a fast forward in Git?
When you try to merge one commit with a commit that can be reached by following the first commit’s history, Git simplifies things by moving the pointer forward because there is no divergent work to merge together – this is called a “fast-forward.”

Is rebasing fast forwarding?
No, that is called rebasing, of which fast-forwarding is a special case when there are no commits to be replayed (and the target branch has new commits, and the history of the target branch has not been rewritten, so that all the commits on the target branch have the current one as their ancestor.) Share. Improve this answer.
What happens when you merge
Git does a number of things to ensure your project's history is maintained whenever commits from separate branches are merged back in. In the event that there are conflicts of any kind between the new code being merged in and the existing code in the main branch, Git will request that someone intervene to resolve them.
How to fast-forward merge with Git
You can fast-forward merge Git without explicitly telling it to do so by ensuring no new changes have been performed on your main branch since your feature branch was first generated. Of course, this is not always a possibility with fast-moving projects being worked on by large, distributed teams.

This has the advantage of keeping track of branches more explicitly than fast-forward merge. If you want to get the same behavior in ...
How does rebasing work?
Rebasing works by abandoning some commits and creating new ones. Rebasing can cause problem when working in public repositories. It can cause extra merge work for your collaborators; You may want to prevent these problems before they start. You can do this with the Branch permissions dialog.
Which branch has 45TP2 commits?
The green branch and the blue main branch both have the 45tP2 commit in their history. The branch had a single commit (and could have had several) before the merge. The branch is ahead of the main branch at the point of the merge. The main branch had no commits; It never diverged from the branch.
Does the main branch have commits?
The main branch had no commits; It never diverged from the branch. At the time of the merge, Git recognizes this situation, so it fast forwards the main branch's pointer to match the merged commits. The merge message tells you about the fast forward: After the merge, users can delete the branch as it no longer needed – the main branch points to ...
Can you delete a branch after a merge?
