My team likes to have a "clean" git history, and likes commits to be squashed before I request a code review. One aspect of this workflow I'm having trouble with:
I want to work on feature-branch-2 (which depends on the stuff in feature-branch-1) while feature-branch-1 is under review. So:
git checkout -b feature-branch-2 feature-branch
Add some commits to feature-branch-2 while I work.
Code review comments come back, so I add some commits to feature-branch-1 that respond to them. Then I squash those commits, and post again for review.
But now I've got a problem: How do I easily bring feature-branch-2 up-to-date with the fixes to feature-branch-1? This would be an easy merge if I hadn't squashed feature-branch-1's commits, but I'm not sure what's an easy workflow with the squashes.
Since you are rewriting history by squashing, thereby removing the parent commit of your feature-branch-2, the only way I can think of is to rebase. After feature-branch-1 is updated you can do.
git checkout feature-branch-2
git rebase feature-branch-1
