I used CVS and ClearCase before moving into Git, and it took me some time to adjust to the fact that the cost of branching in Git is much much less than ClearCase. And getting into the “distributed” mindset didn’t happen overnight.

Yeah I get what you’re saying. Gitlab can pretty much do that too, you just need a branch & MR for each commit, and then you tell it to merge each branch into the previous one. It automatically rebases them when their dependency merges.
Definitely more tedious to set up than just pushing one branch though. Maybe I should make a tool for that… Does Gerrit test each patch in CI sequentially or just all of them together?
But in any case that wasn’t really the problem I was talking about. What I’m saying is that whether or not you should squash a branch depends on what that branch is. Neither “always squash” not “never squash” are right. It depends. And developers seem to have a real problem with knowing when a change is important enough to warrant a commit.
Though I suppose if people have to actually review each commit they would get a lot more push-back to “fix fix fix” type commits so maybe you are right.
Does Gerrit require each individual commit to be approved or can you just approve the whole branch/changeset?
Yeah you’ve gotten the idea I was going for. The workflow of gerrit incentivises forming commits with single ideas. It’s not always squash or never squash, it’s squash when it makes sense to. You still have to stay on top of reviews to get devs to do it, but it’s so much easier that there’s no excuse.
For CI, it depends how you set it up but usually you would test each commit in the relation chain to ensure they’re cherry pickable, back portable. It also helps to push devs to make commits single well contained ideas. Patches higher up in the relation chain will build with the patches below it.
Often you’ll push a relation chain up, get reviews on all of them, get green from CI on all, and then merge them all together. Normally you would set it up to rebase the commits and ff merge them to main.
