- One thing I've desperately wanted from git worktrees is to use reflinking in some way to lower the cost of copies.
I just found https://github.com/josharian/git-cow-worktree that doesn't inspire confidence.
- Like many of you I also knew what git worktrees were but always found them clunky because you mentally had to manage worktrees AND branches at the same time. That's why I didn't bother using them.
A couple of weeks ago I discovered Worktrunk. That's when my whole workflow flipped 180 degrees: I now always use worktrees, love it, will never go back. Worktrunk was the missing piece for me. Very recommended.
by chrizel - Worktrees aren't about filesystem cost. A clean copy that shares objects is what you want when handing repo access to agents and secrets live in the main tree.by chukar
- As the author, I have been using worktrees due to AI agents. And I love Magit but didn’t know it handles git worktrees so well! Thanks for letting me know, will start using magit to manage my worktrees immediately.by brabel
- The problem I have with worktrees is that if I want to test the changes I need to juggle the worktrees.
It works better for me if I have multiple copies of the repo with their own supporting environment like repo-a, repo-b, etc. going to app-a.foo.localhost, app-b.foo.localhost, etc.
by cdmckay - Just use copy-on-write clones. They're way more flexible, faster and easier to reason about.
I don't get spending all this time on tooling that tries to ease working with worktrees when they're just not the right abstraction for the way we're working now.
by simonhamp - A slight limitation of worktrees is that you can only have a branch checked out once in all of your worktrees. I guess that's just how git works.
But when I want to checkout a branch that's already checked out in another worktree, Magit just plain refuses. I wish it would offer me to either:
1. Switch to that worktree instead
2. Detach head in the other worktree and checkout here
Would be such an improvement! No excuses though, I love magit and might as well hack this myself. I'm just bad at elisp.
by miggol - To be honest, AI or not, I just don't like to be in the situation where I need multiple checkouts of the same repository. I do it sometimes anyways, but it's not because I'd like to work like that, rather, because something (bad) happened and it needs fixing, and having an extra checkout would help fixing it.
Some things that the post indicates as the problems solved by worktrees to me feel like the (quite common) problems of development environment setup. For example, OP uses worktrees to prevent different tools from competing over files in the working directory of their development environment... Well, a better way to run tests is to not run them from the development environment at all: deploy them to wherever they are supposed to run, and run them there.
Unfortunately, a lot of tools are designed to run code from "dirty" environment by default, take for instance Python developer's love for "pip install -e" or pytest running code from the source directory by default. But, for one's own sanity, these practices are better avoided. Running from the working directory of the development environment means that you, as a developer, have to remember every detail of the state left by the previous run and reassure yourself that none of those changes matter to your next run... I don't trust myself to remember that.
