Automatic merge of pull requests on Github without the merge bubble

Question

The \"This pull request can be automatically merged [Merge pull request]\" button in github is great -- except that it creates merge bubbles.

Is there a way to use this

Answer 1

And.. they fixed it!

See GitHub's blog on squashing your merge commits

If you go to the settings for your repository, you'll see a "Merge Button" section (under Options). It will have 2 buttons available:

Allow merge commits
Add all commits from the head branch to the base branch with a merge commit.

and

Allow squash merging
Combine all commits from the head branch into a single commit in the base branch.

If you uncheck the first option (and left the Allow squash merging checked), PR "merges" will result in rebase and squashes.

Answer 2

No.

The git blog says using this button you always get an --no-ff merge (no fast-forward merge).

You'd have to do a manual merge if you don't want merge bubbles:

git checkout master
git remote add cameronmcefee git://github.com/cameronmcefee/Spoon-Knife.git
git fetch cameronmcefee 
git merge cameronmcefee/my-branch
git push origin master
