I have the branch
master which tracks the remote branch
I want to rename them to
master-old both locally and on the remote. Is this possible?
For other users who tracked
origin/master (and who always updated their local
master branch via
git pull), what would happen after I renamed the remote branch?
git pull still work or would it throw an error that it couldn’t find
Then, further on, I want to create a new
master branch (both locally and remote). Again, after I did this, what would happen now if the other users do
I guess all this would result in a lot of trouble. Is there a clean way to get what I want? Or should I just leave
master as it is and create a new branch
master-new and just work there further on?
The closest thing to renaming is deleting and then re-creating on the remote. For example:
git branch -m master master-old git push remote :master # delete master git push remote master-old # create master-old on remote git checkout -b master some-ref # create a new local master git push remote master # create master on remote
However this has a lot of caveats. First, no existing checkouts will know about the rename – git does not attempt to track branch renames. If the new
master doesn’t exist yet, git pull will error out. If the new
master has been created. the pull will attempt to merge
master-old. So it’s generally a bad idea unless you have the cooperation of everyone who has checked out the repository previously.
Note: Newer versions of git will not allow you to delete the master branch remotely by default. You can override this by setting the
receive.denyDeleteCurrent configuration value to
ignore on the remote repository. Otherwise, if you’re ready to create a new master right away, skip the
git push remote :master step, and pass
--force to the
git push remote master step. Note that if you’re not able to change the remote’s configuration, you won’t be able to completely delete the master branch!
This caveat only applies to the current branch (usually the
master branch); any other branch can be deleted and recreated as above.
