Git rebase (Merge Squash) my feature branch onto another branch
I'm looking for a git command to help me with my feature branches when they're ready to go into Master. This git command would squash all my changes on my branch into a single commit on top of master. I do this today with:
git rebase origin/master
git rebase -i HEAD~4
Where 4 is the number of commits to squash. However, this requires me to know how many commits I have. I do this today by running:
git log HEAD...origin/master
and then counting the commits.
I feel as though there should be a better way to do this. Or is this how everyone else does it, too?
All you have to do is:
git checkout feature_branch
git rebase master
git checkout master
git merge --squash feature_branch
As the docs for git merge --squash say:
Produce the working tree and index state as if a real merge happened (except for the merge information), but do not actually make a commit or move the HEAD, nor record $GIT_DIR/MERGE_HEAD to cause the next git commit command to create a merge commit. This allows you to create a single commit on top of the current branch whose effect is the same as merging another branch (or more in case of an octopus).
After that, you can git commit your changes which are already staged.
Here is what I do, gathered from a lot of experience working in larger teams:
# Get latest from master
git checkout master
git pull --rebase
# rebase master into your feature branch
git checkout feature/my-feature
git rebase master --preserve-merges
# merge feature into master
git checkout master
# DO ONLY ONE of the 2 options below
# if you only have one or (maybe) 2 commits in your feature branch
git merge feature/my-feature
# OR
# this forces an empty merge commit (useful if we need to roll things back)
git merge --no-ff feature/my-feature
# if you use Github, this should also close the pull request
git push origin master
Hope this helps!
I think you are looking for git merge --squash . It should bring in the commits from your feature branch into master and squashes them, so that you can create a single commit.
