I basically only use git merge
like Theo from T3 stack. git rebase
rewrites your commit history, so I feel there’s too much risk to rewriting something you didn’t intend to. With merge
, every commit is a real state the code was in.
It’s not rebase vs merge, it’s rebase AND merge.
Commit your changes into logical commits as you go.
Then just before submitting a pull request, review your own code. That includes reviewing your own commits too, not just the code diff.
Use rebase to:
- Swap commits so that related changes are together
- Edit your commit messages if you find a mistake or now have a better idea of what to put in your messages
- Drop any useless commits that you just end up reverting later
- Squash any two commits together where the first was the meat of desired change and the second was the one thing that you forgot to add to that commit so you immediately followed it up with another commit for that one missing thing.
Then, and only then, after you have reviewed your own code and used rebase to make the git history easier to read (and thus make it easier to review), then you can submit a pull request.
love this approach and it’s what I usually use. I also don’t rebase after opening a PR (GitHub) because force pushing ruins reviewer context in the GH UI. so after the PR is open I merge main/master in instead of rebasing.
It’s correct that
rebase
rewrites history, but it’s important to identify when it’s not acceptable. If you are working on a branch that is shared by others (typicallymain
), you should never userebase
. But it’s an acceptable practice when used properly. I userebase
on my feature branches whenever necessary. If it fell behind themain
branch I dogit fetch
followed bygit rebase origin/main
, resolve the merge conflicts and keep coding. I also use interactiverebase
when I need to tidy things up before merging the feature branch tomain
.Rebasing is fine for any unpushed commits including ones on shared branches.
I use rebase only to clean up some commit messages, squash commits, etc. - essentially to clean up feature branches I wrote. But never rebase to ‘move’ my branch as if it originated from a different commit, because I don’t know necessarily know what changes have been introduced on the other branch (typically main/master), so rebasing on that would leave my commits in a state that they were never tested in, possibly broken / with unintended sideeffects. If I need changes from the other (main) branch in my feature branch (because of feature dependencies, or to fix merge conflicts), I merge it into my branch and can be sure that the commits created before that merge still behave the way they did before that merge - because they were not changed; this can’t be said for rebasing.
I rebase my dev branches on main to get rid of garbage commit messages due to me being lazy.
Squash and merge PRs into main, no merge commits allowed.
I think there are reasonable arguments for allowing rebase and merge to main, but it often doesn’t apply for me.
Merge commits in main will break a lot of out of the box GitOps tools.
I’m okay with squashing consecutive silly commits before a merge, but having worked on a codebase that used the policy described above for a decade before I got there, I really, really hate it. Git blame and other history inspection tools are nearly totally useless. I’ll have access to commit messages, but when things have been shuffled around feature branches for a while, they end up concatenated into mega commits with little hope of figuring out why anyone did anything or what they were thinking when they did it. Some of this might be mitigated if stale branches weren’t deleted, but people don’t like stale branches.
If there are genuinely Git tools that can’t handle merge commits in <current year>, I’d be surprised if they didn’t have Fisher Price or Hasbro written on the side.
The cases where you can use
git pull --rebase
have high overlap with the cases wheregit rebase
is sane.The important thing is when to avoid doing
git push --force
(almost always; if your remote is a personal fork you theoretically could just create an infinite number of similar branch names for your rebases). Though there are edge cases involving local/SSH clones.What does git pull rebase do? If I understand it correctly, it pulls in the remote changes but rebases your changes to be on top of them, instead of merging the remote and local branch? What is the intended usage of it, it sounds like a lot better way how to pull, why not to use it as default pull?
Because rebasing changes the history, which would mess with other people’s copies of the same branch, wherefore it shouldn’t be default.
