What is this fresh hell (broken Rust build on main):

yeah hit it myself.

a1

was never meant to be

You are full of interesting mysteries today 😄

Either an admin merge without green CI, or a semantic merge conflict (that thing solved by merge-queues)

Except the thing it's failing to build is a third-party crate published to

<http://crates.io|crates.io>

, and the thing it's actually failing to compile is a version of

cargo

which was released 8 months ago and has been working fine since

👻

Well TIL that

cargo install

ignores

Cargo.lock

files

not sure if this is related... but I see this:

https://crates.io/crates/cargo-util/0.1.3 getting released caused this problem, I'm not quite sure how/why yet

Thanks Daniel! On it

LMK when thats on

main

I can merge into the 2 PRs I'm caretaking

I'm getting "error: could not find

=0.1.7

in registry

crates-io

with version `*`"

I think that's actually a warning and doesn't matter

Ah ok

I think so, yeah

The output is:

Updating <http://crates.io|crates.io> index
     Ignored package `cargo-ensure-prefix v0.1.7` is already installed, use --force to override
error: could not find `=0.1.7` in registry `crates-io` with version `*`
     Summary Successfully installed cargo-ensure-prefix! Failed to install =0.1.7 (see error(s) above).
error: some crates failed to install

I think that means things are good, even though, ugh messaging 🙂

Re-kicking CI on that PR. It was missing label when CI started

Upstream issue, for the record: https://github.com/rust-lang/cargo/issues/10803

Regarding the “some crates failed to install”: I've had that for quite some time, without noticeable issues (months, at least)
