How can I remove a specific commit in Git?
A friend of mine edited a bunch of files that shouldn't have been edited.I merged his work into mine when I pulled it, or I tried to just pick out the files I wanted.I've been looking and playing for a long time, trying to figure out how to remove the commits that contain the edits to those files, it seems to be a toss up between reverting and rebase, there are no straightforward examples, and the docs assume I know more than I do
The definition of "adjacent" is based on the number of lines from a context diff.If'myfile' was constructed like this.
The second answer was very interesting.Revert Strategy is a feature that has not yet been officially released.You can use git like this.
It should be able to figure out what you meant.I don't know the definition of a strategy or what the list of available strategies is.
git reset will discard all changes in files since the last commit, so avoid it.Try mixed or keep if soft doesn't work.
Rebase can be used to show the log of the last 5 commits, remove lines you don't want, reorder, squash multiple commits in one, or do anything else you want.
If you need full freedom of history editing, you can use reposurgeon, a very fast open source application.
You should apply the changes to the remote after you git push.If your repo doesn't want to remove the commit, you can use git push -f to force the changes.
If you need to force push on a branch, make sure you don't do it if your current checkout is on another branch.When you force push, always specify the remote branch.
notepad file will open when executedDrop after your commit.Click on each word pick that you want to edit and then hit the "I" key to insert mode.You can exit insert mode by hitting the "esc" key.
The changes will be pushed to remote if you sync the git dashboard.
You will have to push if the commit was already on the remote.Since force is considered harmful, use git push.
You should choose if the error is limited to a private branch or if it has been picked up by other people.
Git reverting is an automated tool that creates a new commit.People who pull from your repository won't run into problems when they update, even though you'll see the error and removal in the project history.You need to add myfile and git commit to deal with the conflict because it's not working in an automated manner.You will end up with four commits in your history.
If nobody cares that your history changes, you can rewrite it and remove commit 2.The easiest way to do this is to use git rebase.You can choose not to include the commit if you remove it and pick the other commit messages.Understand the consequences of doing this.
Above simple command won't work if you have commit more changes to 1406cd61 files.The below steps are for cherry picking.
You need admin rights over the git repo to do this.
All commits have been added to your new branch.Check that everything is working as it should.Check the status of everything that has been commited.
If you want to remove git reset, you need to perform a hard reset on the broken branch.
The merged changes should be pushed back to their origin.This will affect the remote repo.git push --branch name
Replacing Step 2 & 3 with Step 8 will allow you to do the process without creating a new branch.
git rebase can be used to remove commits.You may include some commits from a coworker's topic branch into your own, but later decide you don't want them.
Try another strategy if the rebase wasn't successful.Continue with the instructions.
Since the commit history has changed, you may need to push your topic branch to a remote.Give them a heads up if they are working on the same branch.
I was confused about how git rebase -i could be used to remove a commit, so I hope it's ok to write down my test case here.
At this point, HEAD is at the 5th commit and HEAD1 is the 4th.If we want to remove the 3rd commit, we can use the myrepo_git directory.
The results of git rebase -i HEAD are "fatal: Needed a single revision; invalid upstream HEAD"The text editor will open with these contents.
Since we didn't include our requested head, we get all commits.You'll get a response from git rebase if you deleted the line pick 448c212 and saved the file.
When HEAD got to 2nd commit, there was a patch of addcc+dddd which it doesn't know how to add to the existing content.
If you remove the 3rd commit, you either keep the changes introduced by it or you don't.If you don't, you can use a text editor to remove the extra lines.
In order to mark that we've solved the conflict, we need to git add the folder/file.txt.
There is a chance to change the commit message if we open the text editor again and see the line 4th git commit.If you exit the text editor without saving, you'll get:
Now that you have a history like this, you could inspect it with gitk.The contents of the folder/file.txt have the same timestamps as the original commits.
If we had kept the line, we would have had the contents of the 3rd git commit.
This was the kind of reading I wanted to read to start learning how git rebase works, so hopefully it will help others as well.
The bad commit may have been included in a merge commit.Has your commit merge been pulled?You will have to work through the conflicts if you use git reverting.You can either rebase or reverting, but you have to redo the merge first.
We can't help you for the first case.You have to examine the conflicts after you find that the automatic one failed.You can use git status to see where the conflicts are, edit the unmerged files, find the conflicted hunks, figure out how to resolve them, and finally commit.If you use git commit by itself, the message that pops up in your editor should be the template message created by git reverting; you can add a note about how you fixed the conflicts, then save and quit to commit.
Depending on whether you've done more work since the merge, there are two sub cases for fixing the problem before your merge.If you haven't, you can simply git reset and redo the merge.I'm pretty sure you have.You will end up doing something like this.
Let's call them commits A and B because you did some work and pushed it.When you merged your coworkers work into yours, you discovered that your coworker had changed some things he shouldn't have.
You want to get rid of C, D, and D'.These commits already "out there" since you say you merged your coworkers work into yours.It's a no-no to use git rebase.I've tried.
If you haven't pushed E and F to your coworker yet, you can still remove them from the history.This is the work you want to save.This can be done.
The commits E and F are gone and the changes in your workspace are not committed.I would either move them to a branch or turn them into a patch.You can either manually or automatically revert your coworker's work.Re replay your work when you've done that.Conflicts will be in the code you wrote, instead of your coworker's code.
If you've already pushed the work you did after your coworker's commits, you can still try and get a "reverse patch" either manually or using git revert, but since your work is "in the way" you will probably get more merge conflicts and more.Looks like that's what you ended up in...
