This gives a good explanation of squashing multiple commits:
http://git-scm.com/book/en/Git-Branching-Rebasing
but it does not work for commits that have already been pushed. How do I squash the most recent few commits both in my local and remote repos?
When I do git rebase -i origin/master~4 master
, keep the first one as pick
, set the other three as squash
, and then exit (via c-x c-c in emacs), I get:
$ git rebase -i origin/master~4 master
# Not currently on any branch.
nothing to commit (working directory clean)
Could not apply 2f40e2c... Revert "issue 4427: bpf device permission change option added"
$ git rebase -i origin/master~4 master
Interactive rebase already started
where 2f40 is the pick
commit. And now none of the 4 commits appear in git log
. I expected my editor to be restarted so that I could enter a commit message. What am I doing wrong?
git rebase -i master
you will get the editor vm open and msgs something like this
Pick 2994283490 commit msg1
f 7994283490 commit msg2
f 4654283490 commit msg3
f 5694283490 commit msg4
#Some message
#
#some more
Here I have changed pick for all the other commits to "f" (Stands for fixup).
git push -f origin feature/feature-branch-name-xyz
this will fixup all the commits to one commit and will remove all the other commits . I did this and it helped me.
For squashing two commits, one of which was already pushed, on a single branch the following worked:
git rebase -i HEAD~2
[ pick older-commit ]
[ squash newest-commit ]
git push --force
By default, this will include the commit message of the newest commit as a comment on the older commit.
Minor difference to accepted answer, but I was having a lot of difficulty squashing and finally got it.
$ git rebase -i HEAD~4
esc --> :wq
Push to the remote using:
$ git push origin branch-name --force
On a branch I was able to do it like this (for the last 4 commits)
git checkout my_branch
git reset --soft HEAD~4
git commit
git push --force origin my_branch
A lot of problems can be avoided by only creating a branch
to work on & not working on master
:
git checkout -b mybranch
The following works for remote
commits already pushed & a mixture of remote
pushed commits / local
only commits:
# example merging 4 commits
git checkout mybranch
git rebase -i mybranch~4 mybranch
# at the interactive screen
# choose fixup for commit: 2 / 3 / 4
git push -u origin +mybranch
I also have some pull request notes which may be helpful.
When you are working with a Gitlab or Github you can run in trouble in this way. You squash your commits with one of the above method. My preferite one is:
git rebase -i HEAD~4
or
git rebase -i origin/master
select squash or fixup for yours commit. At this point you would check with git status. And the message could be:
On branch ABC-1916-remote
Your branch and 'origin/ABC-1916' have diverged,
and have 1 and 7 different commits each, respectively.
(use "git pull" to merge the remote branch into yours)
And you can be tempted to pull it. DO NOT DO THAT or you will be in the same situation as before.
Instead push to your origin with:
git push origin +ABC-1916-remote:ABC-1916
The + allow to force push only to one branch.
1) git rebase -i HEAD~4
To elaborate: It works on the current branch; the HEAD~4 means squashing the latest four commits; interactive mode (-i)
2) At this point, the editor opened, with the list of commits, to change the second and following commits, replacing pick with squash then save it.
output: Successfully rebased and updated refs/heads/branch-name.
3) git push origin refs/heads/branch-name --force
output:
remote:
remote: To create a merge request for branch-name, visit:
remote: http://xxx/sc/server/merge_requests/new?merge_request%5Bsource_branch%5D=sss
remote:To ip:sc/server.git
+ 84b4b60...5045693 branch-name -> branch-name (forced update)
