OK. Query.
Rebase or merge into current?
I personally never rebase. It always seems to have some problem. I’m surely there’s a place and time for rebasing but I’ve never seen it in action I guess.
Merge commits suck.
My biggest issue with GitHub is that it always squashes and merges. It’s really annoying as it not only takes away from commit history, but it also puts the fork out of sync with the main branch, and I’ll often realize this after having implemented another features, forcing me end up cherry picking just to fix it. Luckily LazyGit makes this process pretty painless, but still.
Seriously people, use FF-merge where you can.
Then again, if my feature branch has simply gone behind upstream, I usually pull and rebase. If you’ve got good commits, it’s a really simple process and saves me a lot of future headaches.
There’s obviously places not to use rebase(like when multiple people are working on a branch), but I consider it good practice to always rebase before merge. This way, we can always just FF-merge and avoid screwing with the Git history. We do this at my company and honestly, as long as you follow good practices, it should never really get too out of hand.

You are aware you’re talking about two different pieces of software?
Yeah, I am. However GitHub, being the biggest Git hosting provider and all that, makes you use merge commits. FF-merges must be done manually from the command line. While this definitely isn’t a problem for me, many people out there just don’t care and merge without a second thought (which, as I said in my comment, results in having to create a new branch and cherry picking the commits onto there).
You should check out the repo options on GitHub. It most definitely supports rebase merges, and you can disable other merge types if desired.
Sounds like I just gotta get better with rebasing. But generally I do my merges clean from local changes. I’ll commit and push, then merge in, push. Then keep working. Not too hard to track but I’ve found it’s the diff at MR time that people really pay attention to. So individual commits haven’t been too crucial.
Always merge when you’re not sure. Rebasing rewrites your commit history, and merging with the squash flag discards history. In either case, you will not have a real log of what happened during development.
Why do you want that? Because it allows you to go back in time and search. For example, you could be looking for the exact commit that created a specific issue using git bisect. Rebasing all the commits in a feature branch makes it impossible to be sure they will even work, since they represent snapshots that never existed.
I’ll never understand why people suggest you should default to rebasing. When prompted about why, it’s usually some story about how it went wrong and it was just easier to do it the wrong way.
I’m not saying never squash or rebase. It depends on the situation but if you had to pick a default, it should be to simply merge.
I’ve always merged. Rebase simplifies the history graph, but realistically I can’t think of a time where that has been important to me, or any of the teams I’ve worked with.
Maybe on some projects with a huge number of concurrent branches it becomes more important, probably less so for smaller teams.
It only matters if you want to be able to use the commit tree and actually find something. Otherwise, there’s no harm in using merges.
I try to structure my commits in a way that minimizes their blast radius, which usually likes trying to reduce the number of files In touch per commit.
For example, my commit history would look like this:
- Add new method to service class
- Use new service class method in worker
And then as I continue working, all changes will be
git commit --fixuped to one of those two commit’s hashes depending on where they occur.And when it’s time to rebase in full, I can do a
git rebase master --interactive --autosquash.This is the way! Small commits with descriptive commit names, then just fixup into a few feature commits. Makes rebase a breeze.
Rebase. Merge into current leaves merge commits in the dev branches.
I usually merge because I like to see commit history as it happened and because rebasing multiple commits with conflicts is more time-consuming than fixing it in one merge commit.
I do rebase smaller changes though to reduce merge commit clutter and like interactive rebase to clean up my local commit mess before pushing.
If the changes are small enough I just do
rebase -Xtheirs main, and look to see if anything looks fucky (git diff main..).I create a new branch locally with git switch --create, pull everything from main, sacrifice a small squirrel, and run the project to make sure everything still works.
If something doesn’t work or I can’t figure out how to resolve conflicts, I quietly switch back to my previous branch like nothing happened. That problem is for future me.
You can just undo the last commit with
git reset --soft HEAD~1
The little median in the middle is the dev who helps them fix their branch over screenshare
Curious question: how many people work on one repo/module/service at your workplace or organization?
I have been vomiting blood since day1 because of merge conflicts everywhere… I’m still trying to get better at git to make my life easier.
About 20 developers on one repo in my case, we use a rebase merge strategy with fairly small feature branches so I think that helps keep merge conflicts down. Another thing is our codebase is LARGE, so changes don’t often conflict.
I see… No one cares here and everyone just merges randomly. We have about 20 people working on one repo as well but a lot of times it’s the changes to the same file 😭
