After we replaced the Cargo.lock files in nixpkgs with cargoHash, I've not come across any package that actually prints out the correct hash that cargoHash is missing if I replace src.rev (or just source in general).

Is this currently broken in Nixpkgs? Anyone got an example of a package this works for? I find this applies to me both with callPackage and overrideAttrs.

Examples being thumbs, nufmt, and even kickoff (which does implement finalAttrs)

In reply to @k900:0upti.me
Overrides are weird, you need to override cargoDeps

I tried, even then I couldn't get a nix build to tell me the correct cargoHash.

The only way I managed to update/edit source was to not set cargoHash, only cargoDeps.lockFile, and using callPackage.

src = newSrc;
cargoDeps = old.cargoDeps.override {
    src = newSrc;
    hash = "";
}

That package doens't have cargoDeps set though, so I'm gonna try the same w/kickoff

As you can see in my previous message's screenshot, I tried that, to no avail. I commented it out after I got the required hash, because my end goal is to figure out how to find cargoHash - I assumed you meant that cargoHash == cargoDeps.hash.

Here's the nix code copied in this time
