Welcome to the Rust community! This is a place to discuss about the Rust programming language.

If Github isn't used for source control, why on earth is it the only auth provider?
Why has crates.io given Microsoft the ability to control who can and cannot publish Rust code?
Namespacing is whatever, but IMO the real issue is the disproportionate and unnecessary amount of power given to a company known for pushing monopolies.
While I don't want to deny the problems of not having namespaces, they will introduce a new set of problems. One issue with Github and similar platforms with namespaces is that a search for a repo turns up multiple projects with the same name under different namespaces. It's always a confusion as to which one is canonical. Another problem is that people are now going to name squat namespaces instead of project names. Imagine somebody registers the serde namespace. Their crates may be mistaken as the canonical one.
Eh, they could change #1 if they allow current non-namespaced packages but don't allow new ones. That's a pretty lazy migration strategy, but they could take it a step further and allow aliases (e.g. serde can be namespace/serde, and that's set on the serde package).
But the bigger issue is that the devs don't want to support namespaces.
#2 is the stronger argument imo. A package manager should not rely on a single external source.
Apparently there's an effort underway. I don't have any more context than this:

I will say that I actually like the flat namespace, but don't have a strong opinion
Why should I believe this?
I followed the link in echelon's HN profile to their GitHub profile. It's the same name, like you'd expect, but I had to check.
If they were a member of the Rust project, they'd have an entry in the rust-lang/team repository, and they don't. The fact that they've written some code in the Rust language doesn't automatically make them trustworthy, or give them information about what happens in closed council meetings.
You should believe it as much as you want. I don't have any inside knowledge myself, I just remembered an HN comment that was relevant to this post and linked it.
I hope they don't end up fragmenting the community or the ecosystem.
Interesting. Nice to know there are more people who agree and with the time to do something. Hopefully something will come of it.
I know a lot of people want namespaces. And I think it would be nice for a bigger project to have an obvious way to show which packages are part of this big project, and which are not. For example the different serde serialization formats would not need to be listed in the docs, but simply be present in one single serde-formats namespaces.
It it does fuck all for type squatting. Sure, now I'm safe from getting malicious code by doing tokio/tokiu-http, but tokiu/tokio-http can still be malicious!
The only solution to type squatting would be a checksum. So instead of adding Tokio to your toml file you'd have to add e.g. tokio-fld, with the fld part being some kind of check that is derived from the name. Similar to a hash, all names that are similar to tokio would get a wildly different suffix.

You are indeed correct. I hadn't considered that!
The checksum idea might work 🤔 That definitely could be possible with the new registry.
I think you could get it with a signature, just like with Linux repos. Basically, the org would sign the metadata so you know it came from that org's key.
That way you'd need both a malicious name and access to the key. You don't need the suffix here, just a section in the toml that lets you list keys per org, and if it changes, you'd get prompted to update it.
I don't think changing is the problem, incorrect initial entry is the problem. Linux has centralized package maintainers, cargo does not (or am I wrong?)
Or do you mean that adding a namespace would require a key and then all crates in that namespace are unlocked? Then only the initial cargo add would be dangerous, all subsequent ones in the same namespace would not require manual confirmation.
Yes, I'm saying that adding a namespace would require a key, and all releases would be signed with that key. That works similarly to installing a separate repo in a Linux distro, you'd import the key and mark it as trusted, and then signatures would be verified for each download.
So yes, only the initial cargo add would be "dangerous," and there would be a prompt for the user to verify that they have the right key (which they could verify on the project homepage).
Isn't github used only as the auth provider? It is not using any git features, just leaning on the security guarantees of github. I don't find this too alarming.
If you want, you can use git links when declaring dependencies in Cargo.toml. So alternative to crates.io is basically any git host already!

Still makes you bound to github. Can't publish to crates.io without github.

What security guarantee does github have? I can create a new account right now with a random email, sign up for crates.io and type-squat a package.

Sure, but how do you discover the package? That's the other function of a registry. Also, I could easily just add another package as a submodule, but that's not the point.
Semver checks don’t work with straight git urls, since you can only link to an explicit branch or commit, not a version.
version can be passed with git actually. And it will need to match with the version set in Cargo.toml from the git source.
I wouldn't call that an alternative to crate registries though (of which, crates.io is only one impl).
Also tangentially related, cargo-vendor is a thing.
Semver strings allows stuff like "version 2.5.x, but below 2.5.6". Then cargo calculates the best solution for satisfying all dependency specifications from all packages using a single version (if possible).
Specifying a version in addition to the git branch doesn't help there at all, because you still have to do it manually then.
Yes. That is in part why I mentioned that it's not a real alternative, and mentioned cargo-vendor as a possible basis for a less manual serviceable solution.
Serviceable, but not necessarily good still. Anti-crates.io extremists would still be better off using an alternative crates registry*.
* That's something that already exists btw. True extremists don't have to wait for the HN leak-promised Good Stuff.
For #2, there isn't anything stopping a separate auth system not through GitHub. Really just needs someone to own the implementation. See https://github.com/rust-lang/crates.io/issues/326#issuecomment-216662599 for past discussion surrounding this.
@onlinepersona Got this issue two days ago. Someone upload a package with same name of mine. I was need to change the name to also upload.
Yep, so did I. Had to come up with a long-version of my package name in order to upload it. Not much of a problem for me as nobody uses the package but me - at the moment. If that ever changes, it'll be confusing.
I don't understand the "serde2" issue. Isn't "someusername/serde" strictly worse than "serde2"?
GitHub being the only auth provider is something the maintainers wanted to fix, but didn't have enough bandwidth to implement. I think they would welcome contributions!
there's https://lib.rs/, never actually used it myself, but it calls itself an alternative to crates.io
That’s just for the web-based UI, not the database behind it.
ah ok, so i'm assuming it doesn't fix either of the issues listed then. thanks.
Not sure how that's an alternative as there's no way to add anything to it. It seems more like an aggregator that a registry.
