Deny rustc::internal lints for rustdoc and clippy #80573

jyn514 · 2021-01-01T04:26:50Z

Fix rustc::internal lints for rustdoc
Deny internal lints only for rustdoc and clippy (previously the lints were ignored for clippy because -Zunstable-options didn't get passed)

r? @Mark-Simulacrum

I changed this to be more general and deny the lints right away - I can split it into two PRs if you like.

Hmm, this errors out in clippy/tests/compile-test.rs because it uses HashMap instead of FxHashMap. But that's not right, because compiletest is a bootstrap tool and doesn't depend on rustc_data_structures. I think I need to find a way to only do this for regular code and not tests? It sounds difficult to do that without special casing clippy though, I can imagine wanting these lints for rustc unit tests.

flip1995 · 2021-01-02T14:35:57Z

I'm good with adding #![allow(rustc::internal)] to clippys compile-test.rs file.

@calebcartwright how do you feel about fixing those lints for rustfmt? Or would you prefer I ignore them?

@calebcartwright how do you feel about fixing those lints for rustfmt? Or would you prefer I ignore them?

Admittedly haven't read the full thread/linked issues, but I feel like rustfmt should be ignored/excluded from this.

Although we periodically run clippy and selectively apply fixes, it's not really part of our inner dev loop and not a fixed gate, and I don't foresee that changing any time soon. If we were to include the internal lints against rustfmt here then we'll inevitably end up in a scenario where we don't find out about a lint failure til an attempted submod bump which would then require a restart of our upgrade dance.

Also, since rustfmt utilizes the rustc internals via the auto publish crates, I really don't want to increase our dependence on said internals unless absolutely necessary or unless the benefits significantly outweigh the drawbacks. Retroactively dealing with breaking rustc internal changes in rustfmt is already painful enough, and that pain gets exacerbated the more we couple ourselves to those internals.

flip1995 · 2021-01-02T17:57:56Z

I think it would be best to make internal lints opt-in rather than opt-out, if that's somehow possible.

It looks like CI is currently failing. Since unlike rustc, rustdoc and clippy are both currently just one crate (and we don't need to lint their dependencies) maybe just easier to directly add the two attributes to their lib.rs?

Hmm, that will work now, but will break after #80524, which was the original motivation. I'll see if I can improve #80524 not to need bootstrap changes, since I agree #![deny(rustc::internal)] is probably a better approach in general.

Mark-Simulacrum · 2021-01-10T00:05:44Z

Hm I admit I haven't followed that PR closely, if this helps it somehow I can take a look.

Note you want to use warn, not deny - we deny warnings in bootstrap and that should include these lints, right?

jyn514 · 2021-01-22T03:52:58Z

Alright, this is finally working. It

denies internal lints only for rustdoc and clippy (previously the lints were ignored for clippy because -Zunstable-options didn't get passed)
fixes the internal lints for rustdoc
