Gitless doesn't change anything about git's concepts, it just abstracts away some commands. So if you think this solves the problems, they're clearly not "conceptual" faults.
I think this is important because people are so quick to jump on the "git is bad" contrarian meme. Git is a fantastic piece of work and the CLI has a variety of issues. On top of this, git is conceptually unintuitive, so the CLI issues make for a worse experience.
The other half of the issue is that git's commands don't follow the abstraction. If each command mapped to a single dag operation, it might make more sense. But they don't (revert).
They shouldn't. I'm not saying that Git doesn't have commands that can be hard to understand fully, but the whole point of any abstraction is to hide the "insides" of any operation so you don't have to think about them.
Having commands for each DAG operation will just add more complexity and expose a structure which you shouldn't be handling manually.
I think in order to really feel comfortable with Git you have reverse that and think about the DAG as the actual interface and the CLI as the clunky implementation you use to modify the DAG.
I think the main problem is that many developers don't think of Git as a DAG, so they don't really understand at a fundamental level what the operations are actually doing.
Once you understand this, Git really does become simple. All you have to do is map each command to the actual operation on the DAG.
Yeah, but the question is whether a DAG is a good mental model for a VCS. Just because that's the underlying data structure doesn't mean it has to be the user interface too.
Exactly. This seems to be a point that the "Git is easy" crew doesn't understand. Not everyone (in fact, very few) find going into that depth for something that's nothing more than a tool to be reasonable. Reminds me of the Gentoo users that used to say compiling everything is a great idea for an OS.
I find that people understand "linearized" concepts easier than other kinds(DAGs included). When elements are left-to-right or top-to-bottom, you can read what is going on at a glance.
So the next major step in VCS technology will most likely do something to help linearize our views and reduce the tangling that comes into play with any tree or graph structure.
I compare it to 10-15 years ago, when functional programming was rather rare. Mid-level OO programmers would complain it was confusing and unfamilar, whereas in reality has beautiful and simple concepts.
Git's use of a DAG is confusing and unfamilar for many programmers, though in reality it's beautiful and simple.
Pretty much this. Fortunately the command you need is usually a quick Google search away, and a sequence of basic invocations of branch, checkout, merge, rebase and commit are usually enough to transform the DAG however you want, even if there are simpler ways to do it.
It is supposed to be, but I am not sure it delivers on that part. That’s another discussion, but for instance I wouldn’t bet on having a random 10 yo kid understand OO beyond the bare Cats and Dogs tutorial everyone goes through at first.
And that’s what I would say about git as well. Even after knowing the internals and how it is supposed to work, I still feel that for a tool it’s pretty unelegant and puts a significant burden on the user to know what needs to be done in what situations.
Yup, second that. My old boss introduced the whole team to Scala and made us attend a weekly tutorial as part of training/team-building. Since then, I try to write stateless functions, methods and objects as much as possible regardless of language or platform.
Git is quite elegant if one has a good grasp of graph theory.
Git is certainly great technically. But one should not need to know graph theory to source control files. And I believe that any version control system that does not follow the convention (that probably predates Linus' existence on Earth) that commit should actually commit changes to server, is, by definition, more4 hard to use than it has any reason to be.
But this might be a good study in why Linux is not taking over the desktop, and unlikely to do so in foreseeable future.

Usually, VCS commands makes some sense (i.e. commit commits), which isn't always the case with Git.
THere are only two version control systems where I ever needed to use commands, rather than being able to do what I need in GUI -- SVN (because it is crap and would corrupt repository all the time, and then you needed to fix it up by hand) and Git, because... well, because Git.
I worked with cvs, perforce, clear case, svn and mercurial before git. And each system force me to learn new concepts and a new set of commands. There is no one universal set. There is no surprise your vcs skills are not transfered to git. And no, some inferior wrapper like subj doesn't help you. It's always better to learn tool.
But checkin had always did the same thing, be it in VSS or PVCS. Sure, there'd be varying capabilities, differences in tooling, but concepts were the same. Git wants to be different for the sake of being different (even if we assume for a moment that one should know anything about DAGs in order to use version control, which is pretty laughable by itself).
I bet you have no problem in remembering what git pull, git checkout, git add, git commit and git push do, isn't it? For everyday work it's enough. You have problem in mastering git, all these nifty logs, diffs, indexes, refs, heads, remotes and other stuff. Other VCS have complex concepts too besides checkins.
It's not even remembering whatever non-standard terminology Linus came up with (although when I am feeling particularly curmudgeony I don't even want to know what push is, and why doing a commit isn't enough). It's a) having to deal with it in the first place, because the management decided to cargo-cult it, even though we are not developing anything resembling Linux kernel (there were no issues using TFS before, they just decided that they want to give Microsoft even more money and got a commercial Github account), and b) that I even have to drop to the CLI in the first place for operations that in any other VCS I could do with a couple clicks right in VS GUI. With TFS I had to use command line maybe once a year, and usually for something not strictly necessary. With SVN it was maybe every c9ouple of weeks to fix up the repository it messed up, With Git it is way too often.
Whatever technical advantages of Git are (and technically it is good), I think it fails as a tool to let me do my job easier.
It's a once a month / once a quarter occurance. I'm not sure if it's because of changes to the webservice or not enough financial backing.
I've basically given up on using early access pijul. I've had a problem with each of the last three versions, primarily pushing to Nest. It wouldn't be an issue if I could install pijul on NearlyFreeSpeech (because then I could self host on a known good version). I want pijul to succeed, its patching model sounds good. Clearly, it's working for some group of people. But I'm not one of them, and it's past where I feel like I'm wasting my time. I'll try again when they're v1.0
Git design is surprisingly clean and simple. The main issue of git is its CLI and commands naming. They are indeed unclear. But again, concept behind is absolutely amazing. You just need to understand that git repo is a series of snapshots and after that all other details become clear.
Naming is difficult. Good names suggest the right metaphore to understand something. But for git, there is nothing similar in physical world. "push" "pull" and "merge" seem ok, but even "branch" is an original concept different of its usual meaning. Maybe git should have used non english words to avoid confusion.
Branch seems to fit the dictionary definition: "something that extends from or enters into a main body or source". And in fact, it didn't originate with git, it's at least as old as CVS.
Love this work!
