Report the `unexpected_cfgs` lint in external macros #132577

Urgau · 2024-11-03T21:14:27Z

This PR marks the unexpected_cfgs lint as being reportable in external macros, as it's probably not the intention of the macro author to leave ineffective cfgs in the users code.

Fixes #132572

The job x86_64-gnu-tools failed!

Fixed in rust-cli/anstyle#229 (thks to @epage)

Let's try again!

Would this need a crater run?

Would this need a crater run?

Evaluating the new unexpected_cfgs warnings coming from external macros on a crater run is doable (although not easy), but I'm not sure what it will give us, a part (obviously) from the number of impacted crates, which I'm not sure how to interpret. A big (or even small) number of warnings would IMO only reinforce the usefulness of enabling the reporting in external macros (not that it needs it to be clear).

Is there something particular you are looking for?

jieyouxu · 2024-11-06T01:58:30Z

No I'm more just curious, because maybe a few crates are affected.

Fixes rust-lang#132572 try-job: aarch64-gnu-debug

This recent change is causing CI to fail: rust-lang/rust#132577 The failure is caused by the `used_linker` feature in code produced by the `ctor::ctor` attribute macro.

Rustc 1.84 (nightly) introduced that the `unexpected_cfg`s lint will now be reported for external macros (see rust-lang/rust#132577), leading to some of our builds failing due to our `level = "forbid"` config of unexpected cfg flags. Here, we add the logging features to the expected features of the workspace to mitigiate this issue and fix builds.

As of nightly-2024-11-20 - specifically [1] - this triggers an `unexpected_cfgs` lint even when emitted in derive-generated code. [1] rust-lang/rust#132577 Fixes #2117 gherrit-pr-id: I9d536f0ea08475afe0b65411b225aa55f4db449a

Since rust-lang/rust#132577 (currently in rust nightly), we get hundreds of lint warnings: ``` warning: unexpected `cfg` condition name: `wasm_bindgen_unstable_test_coverage` --> src/rust/lib.rs:83:1 | 83 | #[wasm_bindgen(start)] ``` The correct solution is to upgrade wasm-bindgen, but legend has it that is difficult. For now, let's silence the lint.
