r? @Mark-Simulacrum for the src/bootstrap changes

Mark-Simulacrum · 2020-04-01T14:08:51Z

bootstrap changes look good (presuming they work, though the mingw-check job should confirm that clippy check works -- and it seems to have passed).

flip1995 · 2020-04-01T15:15:51Z

Does this also enable running (at least UI) tests for Clippy on every PR?

oli-obk · 2020-04-02T08:07:23Z

Does this also enable running (at least UI) tests for Clippy on every PR?

yes. We already run these right now on every PR, but we used to ignore it if clippy failed to successfully run its tests.

When checking for functions that are potential candidates for trait implementations check the function header to make sure modifiers like asyncness, constness and safety match before triggering the lint. Fixes rust-lang#5413, rust-lang#4290

Move cognitive_complexity to nursery As discussed in rust-lang/rust-clippy#5418 (comment); Clippy's current understanding of cognitive complexity is not good enough yet at analyzing code for understandability to have this lint be enabled by default. changelog: Remove cognitive_complexity from default set of enabled lints

Check fn header along with decl when suggesting to implement trait When checking for functions that are potential candidates for trait implementations check the function header to make sure modifiers like asyncness, constness and safety match before triggering the lint. Fixes rust-lang#5413, rust-lang#4290 changelog: check fn header along with decl for should_implement_trait

Downgrade implicit_hasher to pedantic From the [documentation](https://rust-lang.github.io/rust-clippy/master/index.html#implicit_hasher), this lint is intended to suggest: ```diff - pub fn foo(map: &mut HashMap<i32, i32>) { } + pub fn foo<S: BuildHasher>(map: &mut HashMap<i32, i32, S>) { } ``` I think this is pedantic. I get that this lint can benefit core libraries like serde, but that's exactly the use case for pedantic lints; a library like serde will [enable clippy_pedantic](https://github.com/serde-rs/json/blob/fd6741f4b0b3fc90a58a6f578e33a9adc6403f3f/src/lib.rs#L304) and take the time to go through everything possible. Similar for libraries doing a libz blitz style checkup before committing to a 1.0 release; it would make sense to run through all the available pedantic lints then. But otherwise, for most codebases and certainly for industrial codebases, the above suggested change just makes the codebase more obtuse for questionable benefit. changelog: Remove implicit_hasher from default set of enabled lints

Okay, obviously this is ~impossible to review, but I checked over it a bit locally and it looks good.

Only

are actual changes to this repo, the rest is just clippy being moved into the repo.

Mark-Simulacrum · 2020-05-02T12:00:11Z

Yep, I reviewed those three manually.

oli-obk · 2020-05-02T12:37:12Z

Thanks for the quick work! I'm very excited to be trying this out for clippy.

CI logs show, that all Clippy tests passed.

~~Also, currently the clippy fmt test is run on CI. We might want to turn this of, until clippy uses the same rustfmt version + rustfmt.toml as rustc. But this has to be done in Clippy.~~ Nvm, fmt already gets skipped.

Mark-Simulacrum · 2020-05-02T16:35:39Z

Yeah not sure what's up with that. We'll want to remove clippy from toolstate at least for sure since it should always be test-pass now (I suspect the above might be spurious? we're no longer recording clippy toolstate I think as of this PR)

Manishearth · 2020-05-02T17:32:39Z

So is this also gating on subtree clippy? (Not sure if we were doing that in two steps) @oli-obk do we have a set of instructions for what we should do about syncs?

mati865 · 2020-05-02T18:31:39Z

Instructions were added in #70654

flip1995 · 2020-05-02T18:44:52Z

So is this also gating on subtree clippy?

If I understand the changes correctly, Clippy now gets checked like rustdoc. So yes, this also gates at subtree clippy.

matthiaskrgr · 2020-05-02T19:27:10Z

Instructions were added in #70654

Should we have a copy of that inside the clippy repo as well?

flip1995 · 2020-05-02T19:51:18Z

We should change the documentation in clippy that talks about updating clippy in rust-lang/rust (I think that exists?)

oli-obk · 2020-05-02T19:52:10Z

The reason toolstate fails is that we now don't report any toolstate for clippy anymore, and thus toolstate assumes "failure". I completely forgot about that part of toolstate, I'll look into it tomorrow

flip1995 · 2020-05-02T19:56:36Z

src/bootstrap/test.rs

-            if try_run(builder, &mut cargo.into()) {
-                builder.save_toolstate("clippy-driver", ToolState::TestPass);
-            }


This porbably caused rust-highfive to think that clippy is test-fail now.

petrochenkov · 2020-05-03T07:08:54Z

This will break rebase on master for all people in the near future:

error: The following untracked working tree files would be overwritten by checkout:
        src/tools/clippy/.editorconfig
        src/tools/clippy/.gitattributes
        src/tools/clippy/.github/ISSUE_TEMPLATE.md
        src/tools/clippy/.github/PULL_REQUEST_TEMPLATE.md
        src/tools/clippy/.github/deploy.sh
        ...

The solution is to get rid of the clippy submodule before the rebase:

git submodule deinit src/tools/clippy
