As soon as it finds one, it picks it as the starting point for the rebase ( B in the example above). , and so on) it checks if that commit is an ancestor of the current branch head master. This reflog represents the tips of successive git fetch operations on origin, in 'most recent first' order.įor each reflog entry, ( then. To do this, it looks at the reflog of the remote tracking branch ( origin/master, in this case).

This differs from git fetch + git rebase origin/master in that the pull -rebase command tries to find out which commits are really your local ones, and which had come from upstream in an earlier fetch. master is the branch to replay on top of origin/master.B is the old origin/master (before a fetch updated it).origin/master is the new updated origin/master ( B') On the command line, git rebase and git rebase mozilla/central do the right thing.The -i flag stands for interactive the rebase opens an interactive vim editor where you can not only rebase to the second last commit but alter the commit history up to that point in the process as well. What git pull -rebase does, in this case, is: git fetch origin Enter the following command: git rebase -i HEAD2. the current branch has no upstream fatal: The current branch main has no upstream branch.

fatal: invalid upstream 'master' the current branch has no upstream branch error The current branch master has no upstream branch. See ' what does ' git pull -rebase' do?' (origin/master)ī'-D (actual origin/master after changing B and force pushing) The branch 'main' has no upstream branch. SnakE mentions in the comments that git pull -rebase isn't exactly git fetch & git rebase origin/master. I illustrate it in ' master branch and ' origin/master' have diverged, how to 'undiverge' branches'?' If you just rebase without first updating upstream/master, you won't get the same result.

The git pull -rebase will fetch ( git fetch) first, updating upstream/master commits. merge : Use git merge to apply updates (rather. Here is how it will look on your prompt once you've configured it: nick-macbook-air:~/dev/projects/stash$Īnd this is what you'll need to add to your. fetch-HEAD : Fetch the upstream repository to detect if the HEAD installation of the formula is outdated. Wouldn't it be nice if you could see this information at your faithful command prompt? I thought so too so I started tapping with my bash chopsticks and cooked it up. Tip of the day: Ahead/Behind numbers in the promptĪfter a fetch, git status shows you how many commits you are ahead or behind of the synced remote branch. Rewriting history of shared repositories and branches is something you should NEVER do. Note: You should do this only when working with your own fork. Personally I prefer to keep the history as clean as possible and go for option three, but different teams have different workflows. You have a few options: git push -f origin feature-x Git checkout -b feature-x #some work and some commits happen #some time passes git fetch upstream git rebase upstream/main Publish with git forkĪfter the above steps, publish your work in your remote fork with a simple push: git push origin feature-xĪ slight problem arises if you have to update your remote branch feature-x after you've published it, because of some feedback from the upstream maintainers. In a standard setup, you generally have an origin and an upstream remote - the latter being the gatekeeper of the project or the source of truth to which you wish to contribute.įirst, verify that you have already setup a remote for the upstream repository, and hopefully an origin too: Let me start by detailing a common setup and the most basic workflow to interact with upstream repositories. Git upstream: Keep up-to-date and contribute I was able to run git rebase -i HEAD2 and then git push origin +master and now I have 2 commits. In this blog, I’ll introduce you to the basics, the gotchas, and even leave you with a cool tip to get you ahead of the curve. I ran git rebase -i HEAD3 and got this error: fatal: Needed a single revision invalid upstream HEAD3. invalid upstream origin/dev/staging > Well, use whatever your. To make sure all contributors are drawing from the same place, you’ll need to know some principles of how git forking interacts with git upstream. First do > git rebase origin/dev/staging > I got. But if you’re not sending those changes back upstream-which means sending it back to the parent repository-you’re at risk for losing track of them, which can cause divergent lines in your repository. Forking projects to make your own changes lets you easily integrate your own contributions.
