Package ID warnings and error(s) querying package graph on most-recent nightly runs

[zeeshanlakhani]

Firstly, just wanted to give a ❤️ and thank you for this project!

Note: This started with the latest version of Rust nightly.

nightly-x86_64-apple-darwin unchanged - rustc 1.77.0-nightly (6ae4cfbbb 2024-01-17)

It does not happen on stable.

After compilation, we get a series of dependency-related warnings like package ID names 0.14.0 (registry+[https://github.com/rust-lang/crates.io-index)](https://github.com/rust-lang/crates.io-index)) which wasn't produced by cargo metadata. Then, as one example, it errors out with:

error: failed to parse messages generated by Cargo

Caused by:
  error querying package graph

Caused by:
  unknown package ID: homestar-functions-add 0.1.0 (path+file:///home/runner/work/homestar/homestar/homestar-functions/add)

This also occurs for me locally with the latest nightly release.

Getting the same thing on internal CI + local tests on 1.77.0-nightly (6ae4cfbbb 2024-01-17).

I did get a working test yesterday on 1.77.0-nightly (098d4fd74 2024-01-16) so presumably it's today's nightly that caused this?

[zeeshanlakhani]

@Tom-Goring yep, seems to be the most recent 01-17 nightly.

This might be caused by:rust-lang/cargo#12914
And it should be fixed by:rust-lang/cargo#13311

Yes, I believe @lvyitian is correct. We treat package IDs as opaque generally so the format change itself isn't a problem. However, we match up the package IDs from cargo metadata with the ones from JSON messages.
