unused [patch] in $CARGO_HOME/config.toml failed loading sysroot metadata #19667
Description
How did it happen?
The cargo metadata invocation for querying libstd metadata fired with the --locked flag. However, when cargo attempted to write a lockfile because there were some unused [patch] entries under CARGO_HOME/config.toml, the command failed due to the presence of the --locked flag.
Code snippet to reproduce
export CARGO_HOME=/tmp/ra-bug/cargo-home
cargo new --lib /tmp/ra-bug/foo
cd /tmp/ra-bug/foo
cargo add empty-library
cat <<EOF > src/lib.rs
fn f() {
let x = Some(1);
}
EOF
cargo new --lib /tmp/ra-bug/empty-library
cat <<EOF > /tmp/ra-bug/empty-library/Cargo.toml
[package]
name = "empty-library"
version = "1.0.0"
edition = "2015"
EOF
cat <<EOF > "$CARGO_HOME/config.toml"
[patch.crates-io]
empty-library = { path = "/tmp/ra-bug/empty-library" }
EOFAnd the open any editor and hover on x
It'll show the following hint:
let x: {unknown}

Possible solutions
Maybe Cargo can have an option to stop writing unused patches? I am not sure if such an option is useful though.
We can perhaps leverage the unstable --lockfile-path flag. And write it to somewhere else so we won't modify the original one. Something like (though I don't like it):
