feat: stabilize auto fix note #11558

A note that some warnings could be fixed by running a cargo fix command was added in #10989 and made to work with clippy in #11399. It has only been turned on for nightly builds so far; this PR would make it show on stable.

The original motivation for making this note nightly only, was to allow for iteration on the message output. There has yet to be any feedback on the message format in the time that it has been on nightly. This was brought up in a recent cargo team meeting and it was thought that we should move forward with showing this on stable.

A passing reference to this was made by Amos at https://fasterthanli.me/series/updating-fasterthanli-me-for-2022/part-1

This suggestion is machine-applicable, which means running "cargo fix" (or accepting the suggestion from your code editor) will fix it automatically. Not only does it make the code simpler (one less byte, yes!), it also means less work for the compiler to do, hence, faster compiles.

@rfcbot fcp merge

Example output

warning: `foo` (lib) generated 1 warning (run `cargo fix --lib -p foo` to apply 1 suggestion)
warning: `foo` (lib test) generated 1 warning (1 duplicate)

From last time, our open questions were

  • Should the message stay in the summary line or be on its own line?
    • The summary line can be very long with the current implementation
  • Should the command be specific or genera?
  • Should the command to run be per target or shown once at the end?
  • Should version control specific flags be added to the command to run?

but not having seen any talk of this feature, we have no way to progress without just stablizing it and refining it from there (or reverting this PR).

Team member @epage 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.

@ehuss ehuss added this to the 1.69.0 milestone Jan 28, 2023
wip-sync pushed a commit to NetBSD/pkgsrc-wip that referenced this pull request Apr 24, 2023
Pkgsrc changes:
 * Adjust patches and cargo checksums to new versions.
 * Sadly, the patch to reduce the cargo verbosity no longer applies,
   so I've asked upstream about the proper way to get the old result.
   (so the build log becomes Quite Bloated for now).

Upstream changes:

Version 1.69.0 (2023-04-20)
==========================

Language
--------

- [Deriving built-in traits on packed structs works with `Copy` fields.]
  (rust-lang/rust#104429)
- [Stabilize the `cmpxchg16b` target feature on x86 and x86_64.]
  (rust-lang/rust#106774)
- [Improve analysis of trait bounds for associated types.]
  (rust-lang/rust#103695)
- [Allow associated types to be used as union fields.]
  (rust-lang/rust#106938)
- [Allow `Self: Autotrait` bounds on dyn-safe trait methods.]
  (rust-lang/rust#107082)
- [Treat `str` as containing `[u8]` for auto trait purposes.]
  (rust-lang/rust#107941)

Compiler
--------

- [Upgrade `*-pc-windows-gnu` on CI to mingw-w64 v10 and GCC 12.2.]
  (rust-lang/rust#100178)
- [Rework min_choice algorithm of member constraints.]
  (rust-lang/rust#105300)
- [Support `true` and `false` as boolean flags in compiler arguments.]
  (rust-lang/rust#107043)
- [Default `repr(C)` enums to `c_int` size.]
  (rust-lang/rust#107592)

Libraries
---------

- [Implement the unstable `DispatchFromDyn` for cell types, allowing
  downstream experimentation with custom method receivers.]
  (rust-lang/rust#97373)
- [Document that `fmt::Arguments::as_str()` may return `Some(_)`
  in more cases after optimization, subject to change.]
  (rust-lang/rust#106823)
- [Implement `AsFd` and `AsRawFd` for `Rc`.]
  (rust-lang/rust#107317)

Stabilized APIs
---------------

- [`CStr::from_bytes_until_nul`]
  (https://doc.rust-lang.org/stable/core/ffi/struct.CStr.html#method.from_bytes_until_nul)
- [`core::ffi::FromBytesUntilNulError`]
  (https://doc.rust-lang.org/stable/core/ffi/struct.FromBytesUntilNulError.html)

These APIs are now stable in const contexts:

- [`SocketAddr::new`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.new)
- [`SocketAddr::ip`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.ip)
- [`SocketAddr::port`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.port)
- [`SocketAddr::is_ipv4`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.is_ipv4)
- [`SocketAddr::is_ipv6`]
  (https://doc.rust-lang.org/stable/std/net/enum.SocketAddr.html#method.is_ipv6)
- [`SocketAddrV4::new`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV4.html#method.new)
- [`SocketAddrV4::ip`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV4.html#method.ip)
- [`SocketAddrV4::port`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV4.html#method.port)

- [`SocketAddrV6::flowinfo`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.flowinfo)
- [`SocketAddrV6::scope_id`]
  (https://doc.rust-lang.org/stable/std/net/struct.SocketAddrV6.html#method.scope_id)

Cargo
-----

- [Cargo now suggests `cargo fix` or `cargo clippy --fix` when compilation warnings are auto-fixable.]
  (rust-lang/cargo#11558)
- [Cargo now suggests `cargo add` if you try to install a library crate.]
  (rust-lang/cargo#11410)
- [Cargo now sets the `CARGO_BIN_NAME` environment variable also for binary examples.]
  (rust-lang/cargo#11705)

Rustdoc
-----

- [Vertically compact trait bound formatting.]
  (rust-lang/rust#102842)
- [Only include stable lints in `rustdoc::all` group.]
  (rust-lang/rust#106316)
- [Compute maximum Levenshtein distance based on the query.]
  (rust-lang/rust#107141)
- [Remove inconsistently-present sidebar tooltips.]
  (rust-lang/rust#107490)
- [Search by macro when query ends with `!`.]
  (rust-lang/rust#108143)

Compatibility Notes
-------------------

- [The `rust-analysis` component from `rustup` now only contains
  a warning placeholder.]
  (rust-lang/rust#101841) This was primarily
  intended for RLS, and the corresponding `-Zsave-analysis` flag
  has been removed from the compiler as well.
- [Unaligned references to packed fields are now a hard error.]
  (rust-lang/rust#102513) This has been
  a warning since 1.53, and denied by default with a future-compatibility
  warning since 1.62.
- [Update the minimum external LLVM to 14.]
  (rust-lang/rust#107573)
- [Cargo now emits errors on invalid characters in a registry token.]
  (rust-lang/cargo#11600)
- [When `default-features` is set to false of a workspace dependency,
  and an inherited dependency of a member has `default-features =
  true`, Cargo will enable default features of that dependency.]
  (rust-lang/cargo#11409)
- [Cargo denies `CARGO_HOME` in the `[env]` configuration table.
  Cargo itself doesn't pick up this value, but recursive calls to
  cargo would, which was not intended.]
  (rust-lang/cargo#11644)
- [Debuginfo for build dependencies is now off if not explicitly
  set. This is expected to improve the overall build time.]

  (rust-lang/cargo#11252)

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they represent
significant improvements to the performance or internals of rustc and related
tools.
