This sounds like a behavioral change to me, can you add a test/example where this is the case? |
|
So something like this now errors? struct Test;
enum Foo {
#[repr(u8)]
Variant,
} |

I've added the example you gave in a previous comment as a test. |

so r=me on the implementation, I think this needs signoff by @rust-lang/lang. This change now errors on disallowed attributes on enum variants, which previously either warned with "unused attribute" or did nothing. struct Test;
enum Foo {
#[repr(u8)]
//[before]~^ WARN unused attribute
//[after]~^^ ERROR attribute should be applied
Variant,
}
#[repr(u8)] //~ ERROR attribute should be applied
fn main() {}Or the following, which currently does not warn, @davidtwco, can you also add that one as a test? struct Test;
enum Foo {
#[inline]
//~^ ERROR attribute should be applied
Variant,
}
fn main() {} |

Feel free to remove the nomination if you are able to resolve this before the meeting. |
This commit modifies `check_attr` so that: - Enum variants are now checked (some attributes would not have been prohibited on variants previously). - `check_expr_attributes` and `check_stmt_attributes` are removed as `check_attributes` can perform the same checks.

We discussed this in the lang team meeting today. The consensus was that we'd like to do this, but that we aren't willing to do so without knowing the practical breakage from crater. (For low enough impact we're probably fine calling it a bug fix and just accepting as-is, but for high enough levels we'd want to delay it to an edition or give up and make it an allowable lint instead, with other possibilities in between too.) @bors try |

https://crates.io/crates/mitrid_core/0.9.4 looks like the only regression here. Has ~250 downloads and wasn't updated in the last two years. Do we want to add a future compat period here or can we just go ahead as is? |
|
This seems reasonable to me. Thoughts from other @rust-lang/lang folks? |

Team member @joshtriplett has proposed to merge this. The next step is review by the rest of the tagged team members: No concerns currently listed. Once a majority of reviewers approve (and at most 2 approvals are outstanding), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up! See this document for info about what commands tagged team members can give me. |

to NetBSD/pkgsrc

this pull request
Feb 14, 2021
Pkgsrc changes:
* Adjust patches, convert tabs to spaces so that tests pass.
* Remove patches which are no longer needed (upstream changed)
* Minor adjustments for SunOS, e.g. disable stack probes.
* Adjust cargo checksum patching accordingly.
* Remove commented-out use of PATCHELF on NetBSD, which doesn't work anyway...
Upstream changes:
Version 1.49.0 (2020-12-31)
============================
Language
-----------------------
- [Unions can now implement `Drop`, and you can now have a field in a union
with `ManuallyDrop<T>`.][77547]
- [You can now cast uninhabited enums to integers.][76199]
- [You can now bind by reference and by move in patterns.][76119] This
allows you to selectively borrow individual components of a type. E.g.
```rust
#[derive(Debug)]
struct Person {
name: String,
age: u8,
}
let person = Person {
name: String::from("Alice"),
age: 20,
};
// `name` is moved out of person, but `age` is referenced.
let Person { name, ref age } = person;
println!("{} {}", name, age);
```
Compiler
-----------------------
- [Added tier 1\* support for `aarch64-unknown-linux-gnu`.][78228]
- [Added tier 2 support for `aarch64-apple-darwin`.][75991]
- [Added tier 2 support for `aarch64-pc-windows-msvc`.][75914]
- [Added tier 3 support for `mipsel-unknown-none`.][78676]
- [Raised the minimum supported LLVM version to LLVM 9.][78848]
- [Output from threads spawned in tests is now captured.][78227]
- [Change os and vendor values to "none" and "unknown" for some targets][78951]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
-----------------------
- [`RangeInclusive` now checks for exhaustion when calling `contains`
and indexing.][78109]
- [`ToString::to_string` now no longer shrinks the internal buffer
in the default implementation.][77997]
- [`ops::{Index, IndexMut}` are now implemented for fixed sized
arrays of any length.][74989]
Stabilized APIs
---------------
- [`slice::select_nth_unstable`]
- [`slice::select_nth_unstable_by`]
- [`slice::select_nth_unstable_by_key`]
The following previously stable methods are now `const`.
- [`Poll::is_ready`]
- [`Poll::is_pending`]
Cargo
-----------------------
- [Building a crate with `cargo-package` should now be independently
reproducible.][cargo/8864]
- [`cargo-tree` now marks proc-macro crates.][cargo/8765]
- [Added `CARGO_PRIMARY_PACKAGE` build-time environment
variable.] [cargo/8758] This variable will be set if the crate
being built is one the user selected to build, either with `-p`
or through defaults.
- [You can now use glob patterns when specifying packages &
targets.][cargo/8752]
Compatibility Notes
-------------------
- [Demoted `i686-unknown-freebsd` from host tier 2 to target tier
2 support.][78746]
- [Macros that end with a semi-colon are now treated as statements
even if they expand to nothing.][78376]
- [Rustc will now check for the validity of some built-in attributes
on enum variants.][77015] Previously such invalid or unused
attributes could be ignored.
- Leading whitespace is stripped more uniformly in documentation
comments, which may change behavior. You read [this post about
the changes][rustdoc-ws-post] for more details.
- [Trait bounds are no longer inferred for associated types.][79904]
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.
- [rustc's internal crates are now compiled using the `initial-exec` Thread
Local Storage model.][78201]
- [Calculate visibilities once in resolve.][78077]
- [Added `system` to the `llvm-libunwind` bootstrap config option.][77703]
- [Added `--color` for configuring terminal color support to bootstrap.][79004]

This PR modifies
check_attrso that:check_expr_attributesandcheck_stmt_attributesare removed ascheck_attributescan perform the same checks. This means that codegen attribute errors aren't shown if there are other errors first (e.g. from other attributes, as shown insrc/test/ui/macros/issue-68060.rschanges below).
