GIT：当我已经提交到master分支后，如何发出请求请求？

Question

My remote repo's master branch looks like this (each one is a commit):

A - B - C - D - E - F - G

I would like to get a code review that diffs C and G (C's changes from B should not be displayed). How do I do this?

Do I have to

- create tmpBranch at master (pointing to G)
- branch from C (newBranch)
- move my master branch to newBranch
- delete newBranch
- push these branch changes to repo
- submit pull request

or is there an easier approach? If no, what are the commands that will do the above?

Answer 1

Branches are just labels to the HEAD commit. So, you essentially just need to change the labels.

It's not a good idea to change public history, unless your repo is your own. So, I'm assuming nobody uses your master branch.

$ git checkout G
$ git checkout -b review-this         # Create the branch to be reviewed.
$ git checkout master
$ git reset --hard C                  # Reset the master to commit C
$ git push -f <remote-name> master    # Force push the master branch
$ git push <remote-name> review-this  # Push the new branch
# Submit the pull request
