If I saw this in my code… I’d just… I’d have a mental breakdown

I literally make a new branch. clone, and use an external merge tool (beyond compare) when my branch has fallen too far behind. I don't trust any of the automated processes.
I suck at git.
I'm currently rebasing 17k commits into my branch. I'm letting it run overnight.
I'm disgusting.
Sometimes I look at the memes around here and wonder wtf y'all are doing. Like, neither my code nor the code at the place I work at are perfect. But I don't think I've ever seen a merge do this. Maybe some of the most diverged merges temporarily had a lot of errors because of some refactoring, but then it was just a few find + replaces away from being fixed again. But those were merges where multiple teams had been working on both the original and the fork for years and even then it was usually pretty okay.
It's really easy to make a gigantic mess using git if you don't know what you're doing. As soon as you learn to keep your history mostly linear all those issues go away.

This is true. I got really good at fixing merge conflicts in college
You kinda have to when half of your "team" is barely even able to write code.
rerere makes resolving these almost bearable
Narrator: But it could, in fact, hurt him...
Git flow eliminated 95% of merging issues for my team
To be fair, this is also how VS looks when you open a project fresh from the clone. Or after updating .net versions. .NET is awful about losing references and then claiming thousands of errors. Sometimes just running the build will fix it by relinking the DLLs it couldn't find.
But also yes, VS with a team can be "fun" if people don't sync their formatting settings. I once had a junior that kept converting spaces to tabs on every file he'd touch. You'd get it fixed and then he'd screw up his settings again with a VS update or something.
Try programming in Dart. Dart's static analyser and package manager will go nuts 0.0001 seconds before the fucking packages load

No
Tabs > spaces
Tabs does allow you to set the spacing you need.
Spaces are like hardcoding passwords
Yeah, tabs are larger spaces, what's your point?
/s
You may be right, but I still have an unreasonable hate for tabs in code
Both tabs and spaces are stupid.
It's ridiculous that in 2024, code formatting is still embedded in the source instead of being a style you apply.
Tabs for indenting and spaces for aligning. There. Everybody wins and loses.
This way the code always looks aligned and if you prefer 4 spaces for a tab instead of 2 or 3 or 8 you can just set it in your IDE.
Crisis averted!
And I for spaces.
Let's hate both and be mad at the client?
I like the way you think.
Jokes on merge.. when a rebase editing goes wrong after +15 commits and six hours, and git hits you with a leadpipe: "do it. Do it again, or reassemble your branch from the reflog." I.e. you commited a change very early, went over bunch of commits resolving/fixing/improving them and at middle way forget if you should commit --amend or rebase --continue to move forward. Choose wrong, and two large change-sets get irreversilbly squashed together (that absolutely shouldn't), with no way to undo. Cheers. 👍
You need to merge more often.
Rebase. That's where the real trauma is.
Neither rebasing nor merging should cause trauma if everyone on the team takes a day or two to understand git
You and I have very different opinions on what is a reasonable expectation for our respective teams.
You think it's unreasonable for a software developer to take one to two days to learn a tool that's basically ubiquitous in their field?
No, I think it's a perfectly reasonable thing to do, my coworkers on the other hand...
I consider myself above average in terms of Git know how. But I've come across situations using rebase where you're stuck resolving the same conflicts over several commits.
I still don't understand that part quite well.
This doesn't happen when you do a normal merge though. Making it easier to manage
I usually squash my local into a single commit, then rebase it onto the head of main. Tends to be simpler
Ditto.
Another solution to this situation is to squash your changes in place so that your branch is just 1 commit, and then do the rebase against your master branch or equivalent.
Works great if you're willing to lose the commit history on your branch, which obviously isn't always the case.
Yeah that's what I did as a workaround. Reset (soft) to the first parent commit and do a single commit with all the changes.
The reason for this is that git rebase is kind of like executing a separate merge for every commit that is being reapplied. A proper merge on the other hand looks at the tips of the two branches and thus considers all the commits/changes "at once."
You can improve the situation with git rerere
I don't think rerere applies here. Once you do a rebase, the rewritten commits should contain the conflict resolutions. The only way conflicts could reoccur on subsequent rebases is if changes reoccur in those same files/lines.
Holy shit! I never took the time to read about it rerere. But it all makes sense now.
However, it's still a lot of extra steps for what could otherwise be really simple with a regular merge.
Is there really a big advantage in using rebase vs merge other than trying to keep a single line of progress in the history? It's it really worth all the hassle? Especially if you're using a squash merge in a pull request...
You could try making enabling git's rerere functionality, which stands for "reuse recorded resolution"
Yeah I saw someone else's answer and I totally learned something new today.
That could happen if the base branch has changed a lot since the last time you rebased against it. Git may make you resolve new conflicts that look similar to the last time you resolved them, but they are in fact new conflicts, as far as git can tell.
All it can take is one commit in the parent branch. If your branch has many commits because you're a commit freak then your fucked.
Only if there are changes in the same files and on the same lines in both branches. And if you're a commit freak, you should probably be squashing/amending, especially if you're making multiple commits of changes on the same lines in the same files. The --amend flag exists for a reason. No one needs to see your "fixed things", "changed things again", "fixed it for real" type commits.
What I do locally on my branch is my own business.
Honestly, when doing a merge/pull request into the parent branch, that's when you squash. You don't need the entire history of a development branch in main.
What I do locally on my branch is my own business.
Lol ok, but don't expect git to read your mind. Like I said earlier, if people take a day or two to understand the tool, they can adjust their personal workflows to work better within the confines of git.
I agree.
Unfortunately, from experience, nobody seems to have time for that. They just learn git pull, push, add, commit and merge and that's about it.
Sometimes they'll use checkout and end up in detached head and have a panic attack. That's when I come in. lol
And the branch should be alive a shorter period
Absolutely
