Anyone mind explaining to me how
git rebaseis worth the effort?git mergehas it's own issues but I just don't see any benefit to rebase over it.I use interactive rebases to clean up the history of messy branches so they can be reviewed commit by commit, with each commit representing one logical unit or type of change.
Mind you, getting those wrong is a quick way to making commits disappear into nothingness. Still useful if you're careful. (Or you can just create a second temporary branch you can fall back onto of you need up your first once.)
This 100%. I hate getting added to a PR for review with testing commits in the history, and I'm expected to clean those up before merging into main.
I feel like squash and merge on GitHub/GitLab is nicer for that anyway though, it makes the main branch so much cleaner automatically
If you're using "trunk-based development" (everything is a PR branch or in main), this works great.
If you're using GitFlow, it can make PRs between the major prod/dev/staging branches super messy. It would be nice if GitHub would let you define which merge strategies are allowed per-branch, but that's not a thing (AFAIK). So you're probably better off not squashing in this situation.
Well, rebase allows you to resolve the same conflict ten times in a row instead of doing it once. How cool is that?
Nope, you just need to do it once: https://git-scm.com/book/en/v2/Git-Tools-Rerere.
Why would I ruin all the fun?
Squash your branch first
Doesn't this defeat the purpose, may as well merge then no?
Do not merge your unfinished stuff into main.
I don't like merging main into my branch because I don't understand git, and I feel like that can make a confusing history.
The way I structure my commits, it is usually (but not always) easier and more reliable for me to replay my commits one at a time on top of the main branch and see how each relatively small change needs to be adapted in isolation--running the full test suite at each step to verify that my changes were correct--than to be presented with a slew of changes all at once that result from marrying all of my changes with all of the changes made to the main branch at once. So I generally start by attempting a rebase and fall back to a merge if that ends up creating more problems than it solves.
