I've done a fair bit of work ("Your branch is ahead of 'origin/master' by 37 commits.") which really should have gone into its own branch rather than into master
. These commits only exist on my local machine and have not been pushed to origin
, but the situation is complicated somewhat in that other devs have been pushing to origin/master
and I've pulled those changes.
How do I retroactively move my 37 local commits onto a new branch? Based on the docs, it appears that git rebase --onto my-new-branch master
or ...origin/master
should do this, but both just give me the error "fatal: Needed a single revision". man git-rebase
says nothing about providing a revision to rebase
and its examples do not do so, so I have no idea how to resolve this error.
(Note that this is not a duplicate of Move existing, uncommited work to a new branch in Git or How to merge my local uncommitted changes into another Git branch? as those questions deal with uncommitted changes in the local working tree, not changes which have been committed locally.)
This should be fine, since you haven't pushed your commits anywhere else yet, and you're free to rewrite the history of your branch after origin/master
. First I would run a git fetch origin
to make sure that origin/master
is up to date. Assuming that you're currently on master
, you should be able to do:
git rebase origin/master
... which will replay all of your commits that aren't in origin/master
onto origin/master
. The default action of rebase is to ignore merge commits (e.g. those that your git pull
s probably introduced) and it'll just try to apply the patch introduced by each of your commits onto origin/master
. (You may have to resolve some conflicts along the way.) Then you can create your new branch based on the result:
git branch new-work
... and then reset your master
back to origin/master
:
# Use with care - make sure "git status" is clean and you're still on master:
git reset --hard origin/master
When doing this kind of manipulating branches with git branch
, git reset
, etc. I find it useful to frequently look at the commit graph with gitk --all
or a similar tool, just to check that I understand where all the different refs are pointing.
Alternatively, you could have just created a topic branch based on where your master is at in the first place (git branch new-work-including-merges
) and then reset master
as above. However, since your topic branch will include merges from origin/master
and you've not pushed your changes yet, I'd suggest doing a rebase so that the history is tidier. (Also, when you eventually merge your topic branch back to master, the changes will be more obvious.)
If you have a low # of commits and you don't care if these are combined into one mega-commit, this works well and isn't as scary as doing git rebase
:
unstage the files (replace 1 with # of commits)
git reset --soft HEAD~1
create a new branch
git checkout -b NewBranchName
add the changes
git add -A
make a commit
git commit -m "Whatever"
git log --all --decorate --oneline --graph
.
I stuck with the same issue. I have found easiest solution which I like to share.
1) Create new branch with your changes.
git checkout -b mybranch
2) (Optional) Push new branch code on remote server.
git push origin mybranch
3) Checkout back to master branch.
git checkout master
4) Reset master branch code with remote server and remove local commit.
git reset --hard origin/master
One more way assume branch1 - is branch with committed changes branch2 - is desirable branch
git fetch && git checkout branch1
git log
select commit ids that you need to move
git fetch && git checkout branch2
git cherry-pick commit_id_first..commit_id_last
git push
Now revert unpushed commits from initial branch
git fetch && git checkout branch1
git reset --soft HEAD~1
Alternatively, right after you commit to the wrong branch, perform these steps:
git log git diff {previous to last commit} {latest commit} > your_changes.patch git reset --hard origin/{your current branch} git checkout -b {new branch} git apply your_changes.patch
I can imagine that there is a simpler approach for steps one and two.
What about:
Branch from the current HEAD. Make sure you are on master, not your new branch. git reset back to the last commit before you started making changes. git pull to re-pull just the remote changes you threw away with the reset.
Or will that explode when you try to re-merge the branch?
Here is a much simpler way:
Create a new branch On your new branch do a git merge master- this will merge your committed (not pushed) changes to your new branch Delete you local master branch git branch -D master Use -D instead of -d because you want to force delete the branch. Just do a git fetch on your master branch and do a git pull on your master branch to ensure you have your teams latest code.
git reset --hard origin/master
to discard the unpushed change in your master branch.
A simpler approach, which I have been using (assuming you want to move 4 commits):
git format-patch HEAD~4
(Look in the directory from which you executed the last command for the 4 .patch
files)
git reset HEAD~4 --hard
git checkout -b tmp/my-new-branch
Then:
git apply /path/to/patch.patch
In whatever order you wanted.
Checkout fresh copy of you sources git clone ........ Make branch from desired position git checkout {position} git checkout -b {branch-name} Add remote repository git remote add shared ../{original sources location}.git Get remote sources git fetch shared Checkout desired branch git checkout {branch-name} Merge sources git merge shared/{original branch from shared repository}
For me this was the best way:
Check for changes and merge conflicts git fetch Create a new branch git branch my-changes and push to remote Change upstream to new created branch git master -u upstream-branch remotes/origin/my-changes Push your commits to the new upstream branch. Switch back to previous upstream git branch master --set-upstream-to remotes/origin/master
Success story sharing
master
; the rebase rewrites themaster
branch so that the new commits are linearly on top oforigin/master
, thengit branch new-work
creates anew-work
branch pointing at the tip ofmaster
(the current branch) without switching the current branch tonew-work
. So nownew-work
contains all the new commits. Then the reset moves the current branch (stillmaster
) back toorigin/master
.git reset
and various other ways. Thegit branch new-work
is just saying "create a branch pointing at this commit while I remain on my current branch (which is master in this case)". So there's no need to have a command that moves the commits from master to the new branch - you just create a new branch there and when you reset master the new branch is left where master was
