Invert control in struct_lint_level. #68725

jumbatm · 2020-02-01T11:43:00Z

Changes the struct_lint* methods to take a decorate function instead of a message string. This decorate function is also responsible for eventually stashing, emitting or cancelling the diagnostic. If the lint was allowed after all, the decorate function is not run at all, saving us from spending time formatting messages (and potentially other expensive work) for lints that don't end up being emitted.

r? @Centril

Can someone run the benchmark to check that I've done this correctly, and we get at least the same performance boost as #67755? Cheers.

+        span: Option<MultiSpan>,
+        decorate: Box<dyn for<'b> FnOnce(LintDiagnosticBuilder<'b>) + 'd>) {


Why not &dyn here instead?

decorate is FnOnce, so I can't call it through &dyn which matters in cases like these, where a captured variable (in this case, overlap) is moved out of its environment. Using FnOnce also avoids callers having rewrite their decorate function to be Fn when we'll only call it once anyway, giving them the most flexibility in terms of what kind of captures the closure can do.

I'll push changes that remove the Box anyway, to see if we get any sizeable performance gain. I was hoping the time for allocation of the box would be small enough in comparison to the previous time we were spending formatting, but given the results we're seeing, it couldn't hurt to give this a try.

Ah right; we might want to try the other changes first though before doing the unboxing to see what the full impact of unboxing would be.

Curiously, this PR brought some sizeable perf wins in some tests, but interestingly the set seems to be almost entirely disjoint from the wins in #67755.

It would be good to make some of the tweaks I suggested, in particular avoiding the Box::new(...) in favor of &dyn to see if we can make some more gains and perf-test them here.

Marwes · 2020-02-01T20:55:21Z

This haven't updated the BOX_POINTERS lint to make the message lazy https://github.com/rust-lang/rust/pull/67755/files#diff-1651ba5b47f9ffa648d59265d3f94becR115 . Might be other places that are missed as well?

jumbatm · 2020-02-01T21:15:23Z

Oh, yeah, for sure -- here, for example, I've left the caller taking &str, because the the function needs to perform its own modifications in addition to the user's decorate.

Hmm, actually, I can probably still make this function (and other calls) lazy by doing the function-specific things first, before handing off to the user. I'll give this a try.

Centril · 2020-02-02T04:38:34Z

Changing the cx.span_lint methods and friends to also take a decorate sounds like a good idea.

Looks like we got the wins from #67755 as well now + some more. It's looking quite good. Let's adjust the other ones I pointed out as well for a final perf run and then let's merge this (we can perf test the boxing stuff separately).

- Make report_unsafe take decorate function - Remove span_lint, replacing calls with struct_span_lint, as caller is now responsible for emitting. - Remove lookup_and_emit, replacing with just lookup which takes a decorate function. - Remove span_lint_note, span_lint_help. These methods aren't easily made lazy as standalone methods, private, and unused. If this functionality is needed, to be lazy, they can easily be made into Fn(&mut DiagnosticBuilder) that are meant to be called _within_ the decorate function. - Rename lookup_and_emit_with_diagnostics to lookup_with_diagnostics to better reflect the fact that it doesn't emit for you.

- AnonymousParameters::check_trait_item - TypeAliasBounds::check_item - NonSnakeCase::check_snake_case

span_lint was removed. Callers should use the `lint` method now, and call `set_span` within the closure passed to this method.

This is struct_generic, so I am confused by the last sentence.

Good catch. Opened #69077.

Rustup to rust-lang/rust#68725 Preparation for rust-lang/rust#68725 changelog: none

Pkgsrc changes: * Bump rust bootstrap version to 1.42.0, except for Darwin/i686 where the bootstrap is not (yet?) available. Upstream changes: Version 1.43.0 (2020-04-23) ========================== Language -------- - [Fixed using binary operations with `&{number}` (e.g. `&1.0`) not having the type inferred correctly.][68129] - [Attributes such as `#[cfg()]` can now be used on `if` expressions.][69201] **Syntax only changes** - [Allow `type Foo: Ord` syntactically.][69361] - [Fuse associated and extern items up to defaultness.][69194] - [Syntactically allow `self` in all `fn` contexts.][68764] - [Merge `fn` syntax + cleanup item parsing.][68728] - [`item` macro fragments can be interpolated into `trait`s, `impl`s, and `extern` blocks.][69366] For example, you may now write: ```rust macro_rules! mac_trait { ($i:item) => { trait T { $i } } } mac_trait! { fn foo() {} } ``` These are still rejected *semantically*, so you will likely receive an error but these changes can be seen and parsed by macros and conditional compilation. Compiler -------- - [You can now pass multiple lint flags to rustc to override the previous flags.][67885] For example; `rustc -D unused -A unused-variables` denies everything in the `unused` lint group except `unused-variables` which is explicitly allowed. However, passing `rustc -A unused-variables -D unused` denies everything in the `unused` lint group **including** `unused-variables` since the allow flag is specified before the deny flag (and therefore overridden). - [rustc will now prefer your system MinGW libraries over its bundled libraries if they are available on `windows-gnu`.][67429] - [rustc now buffers errors/warnings printed in JSON.][69227] Libraries --------- - [`Arc<[T; N]>`, `Box<[T; N]>`, and `Rc<[T; N]>`, now implement `TryFrom<Arc<[T]>>`,`TryFrom<Box<[T]>>`, and `TryFrom<Rc<[T]>>` respectively.][69538] **Note** These conversions are only available when `N` is `0..=32`. - [You can now use associated constants on floats and integers directly, rather than having to import the module.][68952] e.g. You can now write `u32::MAX` or `f32::NAN` with no imports. - [`u8::is_ascii` is now `const`.][68984] - [`String` now implements `AsMut<str>`.][68742] - [Added the `primitive` module to `std` and `core`.][67637] This module reexports Rust's primitive types. This is mainly useful in macros where you want avoid these types being shadowed. - [Relaxed some of the trait bounds on `HashMap` and `HashSet`.][67642] - [`string::FromUtf8Error` now implements `Clone + Eq`.][68738] Stabilized APIs --------------- - [`Once::is_completed`] - [`f32::LOG10_2`] - [`f32::LOG2_10`] - [`f64::LOG10_2`] - [`f64::LOG2_10`] - [`iter::once_with`] Cargo ----- - [You can now set config `[profile]`s in your `.cargo/config`, or through your environment.][cargo/7823] - [Cargo will now set `CARGO_BIN_EXE_<name>` pointing to a binary's executable path when running integration tests or benchmarks.][cargo/7697] `<name>` is the name of your binary as-is e.g. If you wanted the executable path for a binary named `my-program`you would use `env!("CARGO_BIN_EXE_my-program")`. Misc ---- - [Certain checks in the `const_err` lint were deemed unrelated to const evaluation][69185], and have been moved to the `unconditional_panic` and `arithmetic_overflow` lints. Compatibility Notes ------------------- - [Having trailing syntax in the `assert!` macro is now a hard error.][69548] This has been a warning since 1.36.0. - [Fixed `Self` not having the correctly inferred type.][69340] This incorrectly led to some instances being accepted, and now correctly emits a hard error. [69340]: rust-lang/rust#69340 Internal Only ------------- These changes provide no direct user facing benefits, but represent significant improvements to the internals and overall performance of `rustc` and related tools. - [All components are now built with `opt-level=3` instead of `2`.][67878] - [Improved how rustc generates drop code.][67332] - [Improved performance from `#[inline]`-ing certain hot functions.][69256] - [traits: preallocate 2 Vecs of known initial size][69022] - [Avoid exponential behaviour when relating types][68772] - [Skip `Drop` terminators for enum variants without drop glue][68943] - [Improve performance of coherence checks][68966] - [Deduplicate types in the generator witness][68672] - [Invert control in struct_lint_level.][68725] [67332]: rust-lang/rust#67332 [67429]: rust-lang/rust#67429 [67637]: rust-lang/rust#67637 [67642]: rust-lang/rust#67642 [67878]: rust-lang/rust#67878 [67885]: rust-lang/rust#67885 [68129]: rust-lang/rust#68129 [68672]: rust-lang/rust#68672 [68725]: rust-lang/rust#68725 [68728]: rust-lang/rust#68728 [68738]: rust-lang/rust#68738 [68742]: rust-lang/rust#68742 [68764]: rust-lang/rust#68764 [68772]: rust-lang/rust#68772 [68943]: rust-lang/rust#68943 [68952]: rust-lang/rust#68952 [68966]: rust-lang/rust#68966 [68984]: rust-lang/rust#68984 [69022]: rust-lang/rust#69022 [69185]: rust-lang/rust#69185 [69194]: rust-lang/rust#69194 [69201]: rust-lang/rust#69201 [69227]: rust-lang/rust#69227 [69548]: rust-lang/rust#69548 [69256]: rust-lang/rust#69256 [69361]: rust-lang/rust#69361 [69366]: rust-lang/rust#69366 [69538]: rust-lang/rust#69538 [cargo/7823]: rust-lang/cargo#7823 [cargo/7697]: rust-lang/cargo#7697 [`Once::is_completed`]: https://doc.rust-lang.org/std/sync/struct.Once.html#method.is_completed [`f32::LOG10_2`]: https://doc.rust-lang.org/std/f32/consts/constant.LOG10_2.html [`f32::LOG2_10`]: https://doc.rust-lang.org/std/f32/consts/constant.LOG2_10.html [`f64::LOG10_2`]: https://doc.rust-lang.org/std/f64/consts/constant.LOG10_2.html [`f64::LOG2_10`]: https://doc.rust-lang.org/std/f64/consts/constant.LOG2_10.html [`iter::once_with`]: https://doc.rust-lang.org/std/iter/fn.once_with.html
