cargo add spurious failure

[xd009642]

Problem

Looking at the packages on crates.io I can't see a good reason for this so there's a chance it should be an issue cargo side.

$ cargo add --dev fake --features "uuid derive"
    Updating crates.io index
      Adding fake v3.0.1 to dev-dependencies
             Features:

error: failed to select a version for the requirement `dummy = "^0.9"`
candidate versions found which didn't match: 0.7.0, 0.6.0, 0.5.0, ...
location searched: crates.io index
required by package `fake v3.0.1`
    ... which satisfies dependency `fake = "^3.0.1"` (locked to 3.0.1) of package `rs v0.1.0 (project-rs)`

Hmm just tried cargo add on a clean project and it works so it's definitely a cargo issue. I also removed fake from the manifest where it didn't work and manually wrote the entry and did a cargo check and it grabbed dummy 0.9 as expected. So maybe this is some temporary registry failure?

I've been trying to reproduce this in a clean project and I haven't managed to yet... So hopefully it's something someone here can instantly see what's up or I'll have to keep trying.

Normally I'd expect this from something like #10623 but I'm not seeing anything in the manifest that would suggest an old cargo wouldn't understand the Index entry and it would require somehow using an older cargo than intended.

[xd009642]

Attaching the lockfile just in case something jumps out, but given dummy is written by the fake author and isn't used by something else it's a bit weird... I have used fake on an older project so maybe an older version cached? I'm really not sure and I've been unable to recreate it though 😓

lockfile.zip

Not seeing anything in that lockfile that would give me pause.

Is this open source where you can point us to a specific commit to reproduce this on? Or could you capture a log, redact that, and post it?

e.g.

$ CARGO_LOG=cargo::core::resolver=trace cargo add --dev fake --features "uuid derive"

If there isn't a message in that log saying why a version was ignored, maybe try blowing away your ~/.cargo/registry and trying again. This might affect reproducibility, so maybe back it up first. I've not dug into this but #14894 makes it sound like one of our caches causes errors to be silenced even when tracing and deleting it might cause it to show.

[xd009642]

It's not open source unfortunately!

So I've tried it on past commits, also nuked registry and nuked registry added fake 2.7.0 and then removed it from the project and added fake 3.0 and none of them have managed to reproduce it.

Once I had the issue all the cargo add calls for fake failed potentially because I tried to tweak some other deps and rerun cargo add without changing the cargo.toml or lockfile myself. But after my dummy project, removing it from current project and readding it it worked and I can't recreate it.

I'll happily try any other ideas you have but I'm at a loss on recreating it after all these tries

[epage]

Were you able to get a log?

Could you post ~/.cargo/registry/index/index.crates.io-6f17d22bba15001f/.cache/du/mm/dummy?

[xd009642]

The log had:

   0.917473350s TRACE resolve: cargo::core::resolver: fake[89]>dummy 2 candidates
   0.917477832s TRACE resolve: cargo::core::resolver: fake[89]>dummy trying 0.9.1
   0.917490838s TRACE resolve: cargo::core::resolver: activating dummy v0.9.1

which just seems correct. And the registry contents is:
