I don’t understand how we’re all using git and it’s not just some backend utility that we all use a sane wrapper for instead.
Everytime you want to do anything with git it’s a weird series or arcane nonsense commands and then someone cuts in saying “oh yeah but that will destroy x y and z, you have to use this other arcane nonsense command that also sounds nothing like you’re trying to do” and you sit there having no idea why either of them even kind of accomplish what you want.
There are tons of wrappers for git, but they all kinda suck. They either don’t let you do something the cli does, so you have to resort to the arcane magicks every now and then anyways. Or they just obfuscate things to the point where you have no idea what it’s doing, making it impossible to know how to fix things if (when) it fucks things up.
Git is complicated, but then again, it’s a tool with a lot of options. Could it be nicer and less abstract in its use? Sure!
However, if you compare what goes does, and how it does, to it’s competitors, then git is quite amazing. 5-10 years ago it was all svn, the dark times. Simpler tool and an actual headache to use.
I think in this case, “depth” was am inferior solution to achieve fast cloning, that they could quickly implement. Sparse checkout (“filter”) is the good solution that only came out recently-ish
Lol if an employer can’t have an intelligent discussion about user friendly interface design I’m happy to not work for them.
Every interview I’ve ever been in there’s been some moment where I say ‘yeah I don’t remember that specific command, but conceptually you need to do this and that, if you want I can look up the command’ and they always say something along the lines of ‘oh no, yeah, that makes conceptual sense don’t worry about it, this isn’t a memory test’.
What are you smoking? Shallow clones don’t modify commit hashes.
The only thing that you lose is history, but that usually isn’t a big deal.
--filter=blob:none probably also won’t help too much here since the problem with node_modules is more about millions of individual files rather than large files (although both can be annoying).
git clone --depth=1 <url> creates a shallow clone. These clones truncate the commit history to reduce the clone size. This creates some unexpected behavior issues, limiting which Git commands are possible. These clones also put undue stress on later fetches, so they are strongly discouraged for developer use. They are helpful for some build environments where the repository will be deleted after a single build.
Maybe the hashes aren’t different, but the important part is that comparisons beyond the fetched depth don’t work: git can’t know if a shallowly cloned repo has a common ancestor with some given commit outside the range, e.g. a tag.
Blobless clones don’t have that limitation. Git will download a hash+path for each file, but it won’t download the contents, so it still takes much less space and time.
If you want to skip all file data without any limitations, you can do git clone --filter=tree:0 which doesn’t even download the metadata
Yes, if you ask about a tag on a commit that you don’t have git won’t know about it. You would need to download that history. You also can’t in general say “commit A doesn’t contain commit B” as you don’t know all of the parents.
You are completely right that --depth=1 will omit some data. That is sort of the point but it does have some downsides. Filters also omit some data but often the data will be fetched on demand which can be useful. (But will also cause other issues like blame taking ridiculous amounts of time.)
Neither option is wrong, they just have different tradeoffs.
No, don’t do that. That modifies the commit hashes, so tags no longer work.
git clone --filter=blob:noneis where it’s at.I don’t understand how we’re all using git and it’s not just some backend utility that we all use a sane wrapper for instead.

Mercurial is way better.
There, I said it.
I think in this case, “depth” was am inferior solution to achieve fast cloning, that they could quickly implement. Sparse checkout (“filter”) is the good solution that only came out recently-ish
You are not entirely wrong, but just as some advice I would refrain from displaying fear of the command line in interviews.
Lol if an employer can’t have an intelligent discussion about user friendly interface design I’m happy to not work for them.
Every interview I’ve ever been in there’s been some moment where I say ‘yeah I don’t remember that specific command, but conceptually you need to do this and that, if you want I can look up the command’ and they always say something along the lines of ‘oh no, yeah, that makes conceptual sense don’t worry about it, this isn’t a memory test’.
For a lot of experienced people, command line tools are user friendly interface design.
Command line tools can be, git’s interface is not. There would not be million memes about exiting vim if it was.
Thanks, didn’t know about that one.

But that’s my point: instead of things weirdly not working, they will work instead.
