rustup, fix breakage introduced by https://github.com/rust-lang/rust/pull/53581

Is there a way to run the tests from the rustc repos clippy_lints package?

Is there a way to run the tests from the rustc repos clippy_lints package?

Why? Just run the tests from this repo?

If you need a rustc to run this with, use https://github.com/kennytm/rustup-toolchain-install-master (rustup-toolchain-install-master -n master -f)

Ok, I got it to build but a lot of tests fail, it looks like run-pass chooses the wrong compiler (nightly instead of master) 🤷‍♂️

[matthiaskrgr]

AAAAH the rust-toolchain file was overriding back to nightly behind my back....

I removed it for testing, and all tests pass except for dogfood

Caused by:
  process didn't exit successfully: `/home/matthias/vcs/github/rust-clippy/target/debug/clippy-driver /home/matthias/.rustup/toolchains/master/bin/rustc - --crate-name ___ --print=file-names -C target-cpu=native --crate-type bin --crate-type rlib --crate-type dylib --crate-type cdylib --crate-type staticlib --crate-type proc-macro` (exit code: 101)
--- stderr
error: multiple input filenames provided

(However since clippy compiled fine I assume that dogfood failure is only due to me using the rustc master version wrongly)

Have you tried cargo +master test or how it should be done in CI one day: setting rustup default master and then just cargo test?

[matthiaskrgr]

Ok, I found my mistake, all tests pass now 🎉

Thanks, the tool_attributes feature stabilization was merged a few hours ago. I added that here.

All tests pass for me locally
