I feel like I often would prefer to get the merge conflict. So many times my coworkers will somehow mess up the code I committed when resolving the conflict.

[–] charliespider@lemmy.world 33 points 10 months ago (1 children)

Rebase all of your work branches onto HEAD so that conflicts require refactoring the first commit where things don't match up. This can make conflicts easier to deal with (in my humble opinion) since you deal with conflicts earlier in your commit history as opposed to at the end after ALL of your changes are made.

Plus a linear history is super nice to work with later on.

I always squash my commits before rebasing. Is your way easier? I never really seem to have a problem with merge conflicts.

[–] charliespider@lemmy.world 4 points 10 months ago

We squash when merging. Final git history is super clean and linear.

This way I can wreck their shit instead! Enjoy debugging this one Tim, you obtuse bastard!

[–] UndefinedIsNotAFunction@programming.dev 10 points 10 months ago (1 children)

Dear god yes. Please just let me deal with the conflict before the kids make it worse.

Dam, hate to work where you work. People do it here all the time and never get fired. Fucking drove me to save backups of my changes and literally would have to push my changes again afterwards. Good thing I finally found a place to work where this shit isn't practiced.

I’m usually the one managing merge conflicts, and honestly that’s how I’d prefer it. I’ve had so many instances where my code was bungled because someone didn’t take the time to actually check the conflicts.

[–] Korne127@lemmy.world 12 points 10 months ago (1 children)

Best thing is to add tests if possible to make sure your code doesn't lose the added functionality.

[–] Anticorp@lemmy.ml 6 points 10 months ago

What is this, the billionaires club? Ain't nobody got time for tests!

[–] homoludens@feddit.de 31 points 10 months ago (3 children)

Two new files wouldn't create a merge conflict though (unless they have the same name)?

[–] joby@programming.dev 24 points 10 months ago (2 children)

Git won't let the second person push if their commit history doesn't line up with the origin branch.

It should be trivial to do a git pull --rebase to move your new commit after the upstream version, but as far as I can tell, no one on my current project remembers this (or perhaps they're using gui tools or something). Our log is full of "merge origin/main onto main".

[–] scubbo@lemmy.ml 22 points 10 months ago (2 children)

God I fucking hate merge commits.

[–] ______@lemm.ee 3 points 10 months ago (1 children)

If you use vscode, try out the merge editor. It's a lot clearer to me when the merge diffs are huge.

I would also say to check out the latest branch for each file you commit. If your file is file.tsx checkout file.tsx in the main branch to make sure you know what you're changing.

[–] scubbo@lemmy.ml 2 points 10 months ago

Thanks! I've been tinkering with VS Code (migrating from IntelliJ) recently - I've found that they're at pretty-much feature parity. VS Code makes it much harder to attach a debugger (IME, though I might just not grok it yet), but is more customizable and a lot less of a memory-hog. I think I'm comfortable adopting it as my daily driver. And, as you say, any IDE's Merge Editor is usually clearer than the equivalent direct from the CLI!

However, I wasn't complaining about Merge Conflicts - I do dislike them, but they're a necessary evil (well, until AI can resolve all conflicts itself :P ). Rather, I was complaining about Merge Commits. See my comment here for more context.

[–] joby@programming.dev 2 points 10 months ago (4 children)

I'm guessing you don't mean commits that actually bring updates from a different branch in? I'm responsible for a bunch of commits that catch my feature branch up to main and a couple that bring my branches into main.

If we were working on the same project, what would you want to see for those? This is hosted on a private gh repo, but it's a small shop and we were working on a tight deadline for an MVP release and were not using PRs for the stuff I was working on.

The boss (co-owner of the business) is the Sr dev on the project and until recently was the only sr dev in the whole shop. I actually don't think he has experience with using git in a team context.

One of my other tasks is working on internal docs (which didn't exist before I joined the team) that would include git best practices for branching strategies and commit messages, so I'm interested in what folks who have more experience than I do would like to see as I try to nudge the team practices.

No, fast-forward merges only

Great question. I'm not the one you asked, but I can answer.

Yes, merge commits, though they get useful work done, cause challenges later. If you're using GitHub you can actually disable the 'merge commit' pattern in the repository settings, under 'branch protections', and you'll have a much nicer time moving code between branches in the future.

Since you're working on patterns, if you're using GitHub, here's my best tip - it's related but will also cause some other nice outcomes.

If you're using GitHub, to get a much better branching experience, you can turn on branch protections on 'main' and specifically turn on 'require linear history'. This will let GitHub know that you prioritize the quality of the history in 'main' over that of all other branches.

Related: If your team keeps a 'develop' branch, you'll need to get rid of it at the same time as making this change. Using a 'develop' branch is not compatible with this setup. Code that used to merge to 'develop' should now merge to 'main' and git tags should be what indicates code is ready for production.

With these settings GitHub will nudge your team towards squashing and rebasing when merging, and operations to pull other people's code into your branch will get dramatically easier. (Edit: You'll start to see the keyword 'fast-forward' a lot more often, which is great.)

If you're not using GitHub, you can still look for tools and setups to "require linear history" to get the same benefits.

This Is The Way.

[–] scubbo@lemmy.ml 2 points 10 months ago

I’m guessing you don’t mean commits that actually bring updates from a different branch in?

Yep, in part, I do. Say I'm working on feature which branched off from main. Time's gone by, and there have been commits on both feature and main. I want to integrate (not I am very carefully not using the word merge!) the commits that exist on main into my feature branch so that I can use them. You can make a merge commit to do so, but there's no point in doing so - a git pull --rebase will have the same effect ("My local branch contains both the changes from the upstream, then the changes that I myself have made 'on top of' them") without requiring a merge commit.

But really, what one chooses to do in the privacy of one's own branch is no concern of mine. I can advise and opine, but it doesn't really affect me. What does affect me is when people insist on merging into main. That really irritates me, because it results in horrible tangled non-linear history like this. Ideally, the history of main should be a linear history of changes which each follow on from one another, and a commit and a change are in 1:1 correspondance:

  • the question "which commit is the parent of this one?" should have one answer, not potentially-multiple.
  • there is no value in seeing the development history of the change (all the random "bugfix", "maybe this will work lol", "correct typos" commits) in the history of main. They are maybe useful in the PR, but the change as seen in main should only contain the finished polished-up result.

GitHub's confusingly named "Squash And Merge" (it's a "merge" in the git merge sense, but it doesn't create a Merge Commit! "Squash and commit" or "Squash and push" would be more accurate) results, I think, in the outcome - a single commit on the HEAD of the target branch containing the result of the change. And if that happens, then I don't care if you've been pulling in changes from main to feature via Merge commits or (correctly IMO) via git pull --rebase - because, whatever you've done, your development history will be (correctly) invisible from the commit on main.

(I say "I think" there because I've only recently started using GitHub in a professional capacity. For the decade prior to this I worked at a Big Tech company which had its own in-house Code Review tools which - probably not by coincidence - aligned a lot more closely with how I think about how Git history should be structured)

merge commits that catch my feature branches up to main

You'd be squashing those when you merge back down into main anyway, no?

[–] scubbo@lemmy.ml 2 points 10 months ago

You'd hope so - and if one does, I have no concerns about whatever one chooses to do in the privacy of their own branch - but some people insist on directly merging to main (preserving two parallel histories), rather than squashing their change into a single commit. Savages ;)

[–] nicoweio@lemmy.world 5 points 10 months ago (2 children)

While we're at it, I like to use --autostash in addition.

[–] squaresinger@feddit.de 5 points 10 months ago

Uuh, thanks for that hint! I've been using git over CLI for over 10 years now and never came across that flag.

[–] kameecoding@lemmy.world 4 points 10 months ago

i have autostash set up as part of global config

[–] jamkey@lemmy.world 5 points 10 months ago

I think the idea is both are adding new files and also making changes to various files but his commits to the non-new files caused the conflict. Also, if both new files affect the same deliverable (like a DLL) then that could create a conflict in some cases (though I think that all depends on the build system).

[–] tobimai@startrek.website 4 points 10 months ago

Sometimes git just hates you

[–] squaresinger@feddit.de 21 points 10 months ago

Committing code like an a duel in an old western movie.

[–] Anticorp@lemmy.ml 19 points 10 months ago

I always rush to finish first when I learn someone else is working on the same files. Ain't nobody got time to figure out how to merge your shit with my beautiful, perfect, new feature.

[–] glibg10b@lemmy.ml 18 points 10 months ago (1 children)

Not if you upload different files lol

[–] drewthejedi@lemmy.world 7 points 10 months ago

Exactly. I was going to share this with colleagues but it's wrong

[–] Empathy@beehaw.org 3 points 10 months ago

Pulling changes should be trivial after you've done it a few times.
