How to remove commits from a pull request

Question

I did a pull request but after that I made some commits to the project locally which ended polluting my pull request  I tried to remove it but without any luck   I found some similar questions on StackOverflow but I can t apply what s in there  It s my first pull request on GitHub so it s kinda strange to me how all of this works   The highlighted commit is the one I need to keep and remove all the other stuff  It becomes the fourth commit in the history because I make some merge stuff     my git log   Can someone please explain what s going on and how to fix this problem

If you re removing a commit and don t want to keep its changes  ferit has a good solution    If you want to add that commit to the current branch  but doesn t make sense to be part of the current pr  you can do the following instead    use git rebase -i HEAD n Swap the commit you want to remove to the bottom  most recent  position Save and exit use git reset HEAD  --soft to uncommit the changes and get them back in a staged state  use git push --force to update the remote branch without your removed commit    Now you ll have removed the commit from your remote  but will still have the changes locally

People wouldn t like to see a wrong commit and a revert commit to undo  changes of the wrong commit  This pollutes commit history    Here is a simple way for removing the wrong commit instead of undoing changes with a revert commit     git checkout my-pull-request-branch git rebase -i HEAD n    where n is the number of last commits you want to include in interactive rebase  Replace pick with drop for commits you want to discard  Save and exit  git push --force

So do the following    Lets say your branch name is my branch and this has the extra commits    git checkout -b my branch with extra commits  Keeping this branch saved under     a different name  gitk  Opens git console  Look for the commit you want to keep  Copy the SHA of that commit to a notepad  git checkout my branch  gitk  This will open the git console   Right click on the commit you want to revert to  State before your changes  and click on  reset branch to here   Do a git pull --rebase origin branch name to  merge to git cherry-pick  lt SHA you copied in step 3   gt    Now look at the local branch commit history and make sure everything looks good

This is what helped me    Create a new branch with the existing one  Let s call the existing one branch old and new as branch new  Reset branch new to a stable state  when you did not have any problem commit at all  For example  to put it at your local master s level do the following   git reset    hard master git push    force origin cherry-pick the commits from branch old into branch new git push
