Version 1.56.1 (2021-11-01)
===========================

- New lints to detect the presence of bidirectional-override Unicode
  codepoints in the compiled source code ([CVE-2021-42574])

[CVE-2021-42574]: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-42574

Version 1.56.0 (2021-10-21)
========================

Language
--------

- [The 2021 Edition is now stable.][rust#88100]
  See [the edition guide][rust-2021-edition-guide] for more details.
- [The pattern in `binding @ pattern` can now also introduce new bindings.]
  [rust#85305]
- [Union field access is permitted in `const fn`.][rust#85769]

[rust-2021-edition-guide]:
  https://doc.rust-lang.org/nightly/edition-guide/rust-2021/index.html

Compiler
--------

- [Upgrade to LLVM 13.][rust#87570]
- [Support memory, address, and thread sanitizers on aarch64-unknown-freebsd.]
  [rust#88023]
- [Allow specifying a deployment target version for all iOS targets][rust#87699]
- [Warnings can be forced on with `--force-warn`.][rust#87472]
  This feature is primarily intended for usage by `cargo fix`, rather than
  end users.
- [Promote `aarch64-apple-ios-sim` to Tier 2\*.][rust#87760]
- [Add `powerpc-unknown-freebsd` at Tier 3\*.][rust#87370]
- [Add `riscv32imc-esp-espidf` at Tier 3\*.][rust#87666]

\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.

Libraries
---------

- [Allow writing of incomplete UTF-8 sequences via stdout/stderr on Windows.]
  [rust#83342]
  The Windows console still requires valid Unicode, but this change allows
  splitting a UTF-8 character across multiple write calls. This allows, for
  instance, programs that just read and write data buffers (e.g. copying a file
  to stdout) without regard for Unicode or character boundaries.
- [Prefer `AtomicU{64,128}` over Mutex for Instant backsliding protection.]
  [rust#83093]
  For this use case, atomics scale much better under contention.
- [Implement `Extend<(A, B)>` for `(Extend<A>, Extend<B>)`][rust#85835]
- [impl Default, Copy, Clone for std::io::Sink and std::io::Empty][rust#86744]
- [`impl From<[(K, V); N]>` for all collections.][rust#84111]
- [Remove `P: Unpin` bound on impl Future for Pin.][rust#81363]
- [Treat invalid environment variable names as non-existent.][rust#86183]
  Previously, the environment functions would panic if given a
  variable name with an internal null character or equal sign (`=`).
  Now, these functions will just treat such names as non-existent
  variables, since the OS cannot represent the existence of a
  variable with such a name.

Stabilised APIs
---------------

- [`std::os::unix::fs::chroot`]
- [`UnsafeCell::raw_get`]
- [`BufWriter::into_parts`]
- [`core::panic::{UnwindSafe, RefUnwindSafe, AssertUnwindSafe}`]
  These APIs were previously stable in `std`, but are now also available
  in `core`.
- [`Vec::shrink_to`]
- [`String::shrink_to`]
- [`OsString::shrink_to`]
- [`PathBuf::shrink_to`]
- [`BinaryHeap::shrink_to`]
- [`VecDeque::shrink_to`]
- [`HashMap::shrink_to`]
- [`HashSet::shrink_to`]

These APIs are now usable in const contexts:

- [`std::mem::transmute`]
- [`[T]::first`][`slice::first`]
- [`[T]::split_first`][`slice::split_first`]
- [`[T]::last`][`slice::last`]
- [`[T]::split_last`][`slice::split_last`]

Cargo
-----

- [Cargo supports specifying a minimum supported Rust version in Cargo.toml.]
  [`rust-version`]
  This has no effect at present on dependency version selection.
  We encourage crates to specify their minimum supported Rust
  version, and we encourage CI systems that support Rust code to
  include a crate's specified minimum version in the text matrix
  for that crate by default.

Compatibility notes
-------------------

- [Update to new argument parsing rules on Windows.][rust#87580]
  This adjusts Rust's standard library to match the behavior of the standard
  libraries for C/C++. The rules have changed slightly over time, and this PR
  brings us to the latest set of rules (changed in 2008).
- [Disallow the aapcs calling convention on aarch64][rust#88399]
  This was already not supported by LLVM; this change surfaces this lack of
  support with a better error message.
- [Make `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` warn by default][rust#87385]
- [Warn when an escaped newline skips multiple lines.][rust#87671]
- [Calls to `libc::getpid` / `std::process::id` from `Command::pre_exec`
  may return different values on glibc <= 2.24.][rust#81825]
  Rust now invokes the `clone3` system call directly, when available,
  to use new functionality available via that system call. Older
  versions of glibc cache the result of `getpid`, and only update
  that cache when calling glibc's clone/fork functions, so a direct
  system call bypasses that cache update. glibc 2.25 and newer no
  longer cache `getpid` for exactly this reason.

Internal changes
----------------
These changes provide no direct user facing benefits, but represent
significant improvements to the internals and overall performance
of rustc and related tools.

- [LLVM is compiled with PGO in published x86_64-unknown-linux-gnu artifacts.]
  [rust#88069]
  This improves the performance of most Rust builds.
- [Unify representation of macros in internal data structures.][rust#88019]
  This change fixes a host of bugs with the handling of macros by the compiler,
  as well as rustdoc.

Version 1.55.0 (2021-09-09)
============================

Language
--------
- [You can now write open "from" range patterns (`X..`), which will start
  at `X` and will end at the maximum value of the integer.][83918]
- [You can now explicitly import the prelude of different editions
  through `std::prelude` (e.g. `use std::prelude::rust_2021::*;`).][86294]

Compiler
--------
- [Added tier 3\* support for `powerpc64le-unknown-freebsd`.][83572]

\* Refer to Rust's [platform support page][platform-support-doc] for more
   information on Rust's tiered platform support.

Libraries
---------

- [Updated std's float parsing to use the Eisel-Lemire algorithm.][86761]
  These improvements should in general provide faster string parsing of floats,
  no longer reject certain valid floating point values, and reduce
  the produced code size for non-stripped artifacts.
- [`string::Drain` now implements `AsRef<str>` and `AsRef<[u8]>`.][86858]

Stabilised APIs
---------------

- [`Bound::cloned`]
- [`Drain::as_str`]
- [`IntoInnerError::into_error`]
- [`IntoInnerError::into_parts`]
- [`MaybeUninit::assume_init_mut`]
- [`MaybeUninit::assume_init_ref`]
- [`MaybeUninit::write`]
- [`array::map`]
- [`ops::ControlFlow`]
- [`x86::_bittest`]
- [`x86::_bittestandcomplement`]
- [`x86::_bittestandreset`]
- [`x86::_bittestandset`]
- [`x86_64::_bittest64`]
- [`x86_64::_bittestandcomplement64`]
- [`x86_64::_bittestandreset64`]
- [`x86_64::_bittestandset64`]

The following previously stable functions are now `const`.

- [`str::from_utf8_unchecked`]


Cargo
-----
- [Cargo will now deduplicate compiler diagnostics to the terminal when invoking
  rustc in parallel such as when using `cargo test`.][cargo/9675]
- [The package definition in `cargo metadata` now includes the `"default_run"`
  field from the manifest.][cargo/9550]
- [Added `cargo d` as an alias for `cargo doc`.][cargo/9680]
- [Added `{lib}` as formatting option for `cargo tree` to print the `"lib_name"`
  of packages.][cargo/9663]

Rustdoc
-------
- [Added "Go to item on exact match" search option.][85876]
- [The "Implementors" section on traits no longer shows redundant
  method definitions.][85970]
- [Trait implementations are toggled open by default.][86260] This should
  make the implementations more searchable by tools like `CTRL+F` in
  your browser.
- [Intra-doc links should now correctly resolve associated items (e.g. methods)
  through type aliases.][86334]
- [Traits which are marked with `#[doc(hidden)]` will no longer appear in the
  "Trait Implementations" section.][86513]


Compatibility Notes
-------------------
- [std functions that return an `io::Error` will no longer use the
  `ErrorKind::Other` variant.][85746] This is to better reflect that these
  kinds of errors could be categorised [into newer more specific `ErrorKind`
  variants][79965], and that they do not represent a user error.
- [Using environment variable names with `process::Command` on Windows now
  behaves as expected.][85270] Previously using envionment variables with
  `Command` would cause them to be ASCII-uppercased.
- [Rustdoc will now warn on using rustdoc lints that aren't prefixed
  with `rustdoc::`][86849]

rust: Update to 1.54.

Requested by gdt@, taken from wip, any mismerges are mine and I'll follow up.
While here pull in an additional fix from newer wip to disable the docs (they
are absolutely huge and not all that useful).

Version 1.54.0 (2021-07-29)
============================

Language
-----------------------

- [You can now use macros for values in built-in attribute macros.][83366]
  While a seemingly minor addition on its own, this enables a lot of
  powerful functionality when combined correctly. Most notably you can
  now include external documentation in your crate by writing the following.
  ```rust
  #![doc = include_str!("README.md")]
  ```
  You can also use this to include auto-generated modules:
  ```rust
  #[path = concat!(env!("OUT_DIR"), "/generated.rs")]
  mod generated;
  ```

- [You can now cast between unsized slice types (and types which contain
  unsized slices) in `const fn`.][85078]
- [You can now use multiple generic lifetimes with `impl Trait` where the
   lifetimes don't explicitly outlive another.][84701] In code this means
   that you can now have `impl Trait<'a, 'b>` where as before you could
   only have `impl Trait<'a, 'b> where 'b: 'a`.

Compiler
-----------------------

- [Rustc will now search for custom JSON targets in
  `/lib/rustlib/<target-triple>/target.json` where `/` is the "sysroot"
  directory.][83800] You can find your sysroot directory by running
  `rustc --print sysroot`.
- [Added `wasm` as a `target_family` for WebAssembly platforms.][84072]
- [You can now use `#[target_feature]` on safe functions when targeting
  WebAssembly platforms.][84988]
- [Improved debugger output for enums on Windows MSVC platforms.][85292]
- [Added tier 3\* support for `bpfel-unknown-none`
   and `bpfeb-unknown-none`.][79608]

Libraries
-----------------------

- [`panic::panic_any` will now `#[track_caller]`.][85745]
- [Added `OutOfMemory` as a variant of `io::ErrorKind`.][84744]
- [ `proc_macro::Literal` now implements `FromStr`.][84717]
- [The implementations of vendor intrinsics in core::arch have been
   significantly refactored.][83278] The main user-visible changes are
   a 50% reduction in the size of libcore.rlib and stricter validation
   of constant operands passed to intrinsics. The latter is technically
   a breaking change, but allows Rust to more closely match the C vendor
   intrinsics API.

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

- [`BTreeMap::into_keys`]
- [`BTreeMap::into_values`]
- [`HashMap::into_keys`]
- [`HashMap::into_values`]
- [`arch::wasm32`]
- [`VecDeque::binary_search`]
- [`VecDeque::binary_search_by`]
- [`VecDeque::binary_search_by_key`]
- [`VecDeque::partition_point`]

Cargo
-----

- [Added the `--prune <spec>` option to `cargo-tree` to remove a package from
  the dependency graph.][cargo/9520]
- [Added the `--depth` option to `cargo-tree` to print only to a certain depth
  in the tree ][cargo/9499]
- [Added the `no-proc-macro` value to `cargo-tree --edges` to hide procedural
  macro dependencies.][cargo/9488]
- [A new environment variable named `CARGO_TARGET_TMPDIR` is available.][cargo/9375]
  This variable points to a directory that integration tests and benches
  can use as a "scratchpad" for testing filesystem operations.

Compatibility Notes
-------------------
- [Mixing Option and Result via `?` is no longer permitted in closures for inferred types.][86831]
- [Previously unsound code is no longer permitted where different constructors in branches
  could require different lifetimes.][85574]
- As previously mentioned the [`std::arch` instrinsics now uses stricter const checking][83278]
  than before and may reject some previously accepted code.
- [`i128` multiplication on Cortex M0+ platforms currently unconditionally causes overflow
   when compiled with `codegen-units = 1`.][86063]

Version 1.53.0 (2021-06-17)
============================

Language
-----------------------
- [You can now use unicode for identifiers.][83799] This allows multilingual
  identifiers but still doesn't allow glyphs that are not considered characters
  such as `~W~F` or `~_~@`. More specifically you can now use any identifier that
  matches the UAX #31 "Unicode Identifier and Pattern Syntax" standard. This
  is the same standard as languages like Python, however Rust uses NFC
  normalization which may be different from other languages.
- [You can now specify "or patterns" inside pattern matches.][79278]
  Previously you could only use `|` (OR) on complete patterns. E.g.
  ```rust
  let x = Some(2u8);
  // Before
  matches!(x, Some(1) | Some(2));
  // Now
  matches!(x, Some(1 | 2));
  ```
- [Added the `:pat_param` `macro_rules!` matcher.][83386] This matcher
  has the same semantics as the `:pat` matcher. This is to allow `:pat`
  to change semantics to being a pattern fragment in a future edition.

Compiler
-----------------------
- [Updated the minimum external LLVM version to LLVM 10.][83387]
- [Added Tier 3\* support for the `wasm64-unknown-unknown` target.][80525]
- [Improved debuginfo for closures and async functions on Windows MSVC.][83941]

Libraries
-----------------------
- [Abort messages will now forward to `android_set_abort_message` on
  Android platforms when available.][81469]
- [`slice::IterMut<'_, T>` now implements `AsRef<[T]>`][82771]
- [Arrays of any length now implement `IntoIterator`.][84147]
  Currently calling `.into_iter()` as a method on an array will
  return `impl Iterator<Item=&T>`, but this may change in a
  future edition to change `Item` to `T`. Calling `IntoIterator::into_iter`
  directly on arrays will provide `impl Iterator<Item=T>` as expected.
- [`leading_zeros`, and `trailing_zeros` are now available on all
  `NonZero` integer types.][84082]
- [`{f32, f64}::from_str` now parse and print special values
  (`NaN`, `-0`) according to IEEE RFC 754.][78618]
- [You can now index into slices using `(Bound<usize>, Bound<usize>)`.][77704]
- [Add the `BITS` associated constant to all numeric types.][82565]

Cargo
-----------------------
- [Cargo now supports git repositories where the default `HEAD` branch is not
  "master".][cargo/9392] This also includes a switch to the version 3 `Cargo.lock` format
  which can handle default branches correctly.
- [macOS targets now default to `unpacked` split-debuginfo.][cargo/9298]
- [The `authors` field is no longer included in `Cargo.toml` for new
  projects.][cargo/9282]

Rustdoc
-----------------------
- [Added the `rustdoc::bare_urls` lint that warns when you have URLs
  without hyperlinks.][81764]

Compatibility Notes
-------------------
- [Implement token-based handling of attributes during expansion][82608]
- [`Ipv4::from_str` will now reject octal format IP addresses in addition
  to rejecting hexadecimal IP addresses.][83652] The octal format can lead
  to confusion and potential security vulnerabilities and [is no
  longer recommended][ietf6943].
- [The added `BITS` constant may conflict with external definitions.][85667]
  In particular, this was known to be a problem in the `lexical-core` crate,
  but they have published fixes for semantic versions 0.4 through 0.7. To
  update this dependency alone, use `cargo update -p lexical-core`.
- Incremental compilation remains off by default, unless one uses the
  `RUSTC_FORCE_INCREMENTAL=1` environment variable added in 1.52.1.

Update lang/rust to version 1.52.1.

Pkgsrc changes:
 * Bump bootstrap kit version to 1.51.0.
 * Adjust patches as needed.
 * Update checksum adjustments.
 * Fix syntax error in commands adjusting libserde_derive for Darwin

Upstream changes:

Version 1.52.1 (2021-05-10)
============================

This release disables incremental compilation, unless the user has explicitly
opted in via the newly added RUSTC_FORCE_INCREMENTAL=1 environment variable.

This is due to the widespread, and frequently occuring, breakage encountered by
Rust users due to newly enabled incremental verification in 1.52.0. Notably,
Rust users **should** upgrade to 1.52.0 or 1.52.1: the bugs that are detected by
newly added incremental verification are still present in past stable versions,
and are not yet fixed on any channel. These bugs can lead to miscompilation of
Rust binaries.

These problems only affect incremental builds, so release builds with Cargo
should not be affected unless the user has explicitly opted into incremental.
Debug and check builds are affected.

See [84970] for more details.

[84970]: https://github.com/rust-lang/rust/issues/84970

Version 1.52.0 (2021-05-06)
============================

Language
--------
- [Added the `unsafe_op_in_unsafe_fn` lint, which checks whether
  the unsafe code in an `unsafe fn` is wrapped in a `unsafe`
  block.][79208] This lint is allowed by default, and may become
  a warning or hard error in a future edition.

- [You can now cast mutable references to arrays to a pointer of
  the same type as the element.][81479]

Compiler
--------
- [Upgraded the default LLVM to LLVM 12.][81451]

Added tier 3\* support for the following targets.

- [`s390x-unknown-linux-musl`][82166]
- [`riscv32gc-unknown-linux-musl` & `riscv64gc-unknown-linux-musl`][82202]
- [`powerpc-unknown-openbsd`][82733]

\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.

Libraries
---------
- [`OsString` now implements `Extend` and `FromIterator`.][82121]
- [`cmp::Reverse` now has `#[repr(transparent)]` representation.][81879]
- [`Arc<impl Error>` now implements `error::Error`.][80553]
- [All integer division and remainder operations are now `const`.][80962]

Stabilised APIs
-------------
- [`Arguments::as_str`]
- [`char::MAX`]
- [`char::REPLACEMENT_CHARACTER`]
- [`char::UNICODE_VERSION`]
- [`char::decode_utf16`]
- [`char::from_digit`]
- [`char::from_u32_unchecked`]
- [`char::from_u32`]
- [`slice::partition_point`]
- [`str::rsplit_once`]
- [`str::split_once`]

The following previously stable APIs are now `const`.

- [`char::len_utf8`]
- [`char::len_utf16`]
- [`char::to_ascii_uppercase`]
- [`char::to_ascii_lowercase`]
- [`char::eq_ignore_ascii_case`]
- [`u8::to_ascii_uppercase`]
- [`u8::to_ascii_lowercase`]
- [`u8::eq_ignore_ascii_case`]

Rustdoc
-------
- [Rustdoc lints are now treated as a tool lint, meaning that
  lints are now prefixed with `rustdoc::` (e.g.
  `#[warn(rustdoc::non_autolinks)]`).][80527] Using the old style
  is still allowed, and will become a warning in a future release.
- [Rustdoc now supports argument files.][82261]
- [Rustdoc now generates smart punctuation for documentation.][79423]
- [You can now use "task lists" in Rustdoc Markdown.][81766] E.g.
  ```markdown
  - [x] Complete
  - [ ] Todo
  ```

Misc
----
- [You can now pass multiple filters to tests.][81356] E.g.
  `cargo test -- foo bar` will run all tests that match `foo` and `bar`.
- [Rustup now distributes PDB symbols for the `std` library on Windows,
  allowing you to see `std` symbols when debugging.][82218]

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.

- [Check the result cache before the DepGraph when ensuring queries][81855]
- [Try fast_reject::simplify_type in coherence before doing full check][81744]
- [Only store a LocalDefId in some HIR nodes][81611]
- [Store HIR attributes in a side table][79519]

Compatibility Notes
-------------------
- [Cargo build scripts are now forbidden from setting
  `RUSTC_BOOTSTRAP`.][cargo/9181]
- [Removed support for the `x86_64-rumprun-netbsd` target.][82594]
- [Deprecated the `x86_64-sun-solaris` target in favor of
  `x86_64-pc-solaris`.][82216]
- [Rustdoc now only accepts `,`, ` `, and `\t` as delimiters for specifying
  languages in code blocks.][78429]
- [Rustc now catches more cases of `pub_use_of_private_extern_crate`][80763]
- [Changes in how proc macros handle whitespace may lead to panics
  when used with older `proc-macro-hack` versions. A `cargo update` should
  be sufficient to fix this in all cases.][84136]

Revision 1.10 / (download) - annotate - [select for diffs], Wed May 26 09:21:39 2021 UTC (6 months, 1 week ago) by he
Branch: MAIN
Changes since 1.9: +9 -23 lines
Diff to previous 1.9 (colored)

Update lang/rust to version 1.51.0.

Pkgsrc changes:
 * Add support for the big-endian arm64 NetBSD target (aarch64_be).
 * On NetBSD/i386, use the i586 (pentium) bootstrap kit variant in
   preference to i686.
 * Adjust patches, re-compute line offsets, re-compute crate checksums.
 * Remove a patch which was either integrated upstream and/or no longer
   applies.
 * Bump bootstraps to 1.50.0.
 * Move conditionals until after bsd.prefs.mk so that they work...
 * Default to "dist" build target if cross-compiling, but allow
   also to override via rust.BUILD_TARGET.
 * Allow overriding MAKE_JOBS_SAFE via rust.MAKE_JOBS_SAFE if you
   want a different trade-off between occasional breakage and performance.
 * Adjust platform.mk according to work already done in wip/rust/
 * Add a patch to optimize the install.sh script used to install binary
   bootstraps to not do so many forks; use case/esac and parameter expansion
   instead of grep, sed and cut.
 * Drop building documentation for the binary bootstrap kits.  This will
   also impact the lang/rust-bin package.  For full documentation, build
   or install lang/rust as a package.

Upstream changes:

Version 1.51.0 (2021-03-25)
============================

Language
--------
- [You can now parameterize items such as functions, traits, and
  `struct`s by constant values in addition to by types and
  lifetimes.][79135] Also known as "const generics" E.g. you can
  now write the following. Note:  Only values of primitive integers,
  `bool`, or `char` types are currently permitted.
  ```rust
  struct GenericArray<T, const LENGTH: usize> {
      inner: [T; LENGTH]
  }

  impl<T, const LENGTH: usize> GenericArray<T, LENGTH> {
      const fn last(&self) -> Option<&T> {
          if LENGTH == 0 {
              None
          } else {
              Some(&self.inner[LENGTH - 1])
          }
      }
  }
  ```

Compiler
--------

- [Added the `-Csplit-debuginfo` codegen option for macOS platforms.][79570]
  This option controls whether debug information is split across
  multiple files or packed into a single file. **Note** This option
  is unstable on other platforms.
- [Added tier 3\* support for `aarch64_be-unknown-linux-gnu`,
  `aarch64-unknown-linux-gnu_ilp32`, and
  `aarch64_be-unknown-linux-gnu_ilp32` targets.][81455]

- [Added tier 3 support for `i386-unknown-linux-gnu` and
  `i486-unknown-linux-gnu` targets.][80662]

- [The `target-cpu=native` option will now detect individual features
  of CPUs.][80749]

\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.

Libraries
---------

- [`Box::downcast` is now also implemented for any `dyn Any + Send
  + Sync` object.][80945]
- [`str` now implements `AsMut<str>`.][80279]
- [`u64` and `u128` now implement `From<char>`.][79502]
- [`Error` is now implemented for `&T` where `T` implements `Error`.][75180]
- [`Poll::{map_ok, map_err}` are now implemented for
  `Poll<Option<Result<T,E>>>`.][80968]
- [`unsigned_abs` is now implemented for all signed integer types.][80959]
- [`io::Empty` now implements `io::Seek`.][78044]
- [`rc::Weak<T>` and `sync::Weak<T>`'s methods such as `as_ptr`
  are now implemented for `T: ?Sized` types.][80764]
- [`Div` and `Rem` by their `NonZero` variant is now implemented
  for all unsigned integers.][79134]

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

- [`Arc::decrement_strong_count`]
- [`Arc::increment_strong_count`]
- [`Once::call_once_force`]
- [`Peekable::next_if_eq`]
- [`Peekable::next_if`]
- [`Seek::stream_position`]
- [`array::IntoIter`]
- [`panic::panic_any`]
- [`ptr::addr_of!`]
- [`ptr::addr_of_mut!`]
- [`slice::fill_with`]
- [`slice::split_inclusive_mut`]
- [`slice::split_inclusive`]
- [`slice::strip_prefix`]
- [`slice::strip_suffix`]
- [`str::split_inclusive`]
- [`sync::OnceState`]
- [`task::Wake`]
- [`VecDeque::range`]
- [`VecDeque::range_mut`]

Cargo
-----
- [Added the `split-debuginfo` profile option to control the -Csplit-debuginfo
  codegen option.][cargo/9112]
- [Added the `resolver` field to `Cargo.toml` to enable the new
  feature resolver and CLI option behavior.][cargo/8997] Version
  2 of the feature resolver will try to avoid unifying features of
  dependencies where that unification could be unwanted.  Such as
  using the same dependency with a `std` feature in a build scripts
  and proc-macros, while using the `no-std` feature in the final
  binary. See the [Cargo book documentation][feature-resolver@2.0]
  for more information on the feature.

Rustdoc
-------

- [Rustdoc will now include documentation for methods available
  from _nested_ `Deref` traits.][80653]
- [You can now provide a `--default-theme` flag which sets the
  default theme to use for documentation.][79642]

Various improvements to intra-doc links:

- [You can link to non-path primitives such as `slice`.][80181]
- [You can link to associated items.][74489]
- [You can now include generic parameters when linking to items,
  like `Vec<T>`.][76934]

Misc
----
- [You can now pass `--include-ignored` to tests (e.g. with
  `cargo test -- --include-ignored`) to include testing tests marked
  `#[ignore]`.][80053]

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

- [WASI platforms no longer use the `wasm-bindgen` ABI, and instead
  use the wasm32 ABI.][79998]
- [`rustc` no longer promotes division, modulo and indexing operations
  to `const` that could fail.][80579]
- [The minimum version of glibc for the following platforms has
  been bumped to version 2.31 for the distributed artifacts.][81521]
    - `armv5te-unknown-linux-gnueabi`
    - `sparc64-unknown-linux-gnu`
    - `thumbv7neon-unknown-linux-gnueabihf`
    - `armv7-unknown-linux-gnueabi`
    - `x86_64-unknown-linux-gnux32`
- [`atomic::spin_loop_hint` has been deprecated.][80966] It's
  recommended to use `hint::spin_loop` instead.

Internal Only

Update lang/rust to version 1.50.0.

Pkgsrc changes:
 * Adjust patches, re-compute line offsets, fix capitalization.
 * Remove i686/FreeBSD support, no longer provided upstream.
 * Bump bootstraps to 1.49.0.
 * Change USE_TOOLS from bsdtar to gtar.
 * Reduce diffs to pkgsrc-wip package patches.
 * Allow rust.BUILD_TARGET to override automatic choice of target.
 * Add an i586/NetBSD (pentium) bootstrap variant (needs testing),
   not yet added as bootstrap since 1.49 doesn't have that variant.

Upstream changes:

Version 1.50.0 (2021-02-11)
============================

Language
-----------------------
- [You can now use `const` values for `x` in `[x; N]` array
  expressions.][79270] This has been technically possible since
  1.38.0, as it was unintentionally stabilized.
- [Assignments to `ManuallyDrop<T>` union fields are now considered
  safe.][78068]

Compiler
-----------------------
- [Added tier 3\* support for the `armv5te-unknown-linux-uclibceabi`
  target.][78142]
- [Added tier 3 support for the `aarch64-apple-ios-macabi` target.][77484]
- [The `x86_64-unknown-freebsd` is now built with the full toolset.][79484]

\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.

Libraries
-----------------------

- [`proc_macro::Punct` now implements `PartialEq<char>`.][78636]
- [`ops::{Index, IndexMut}` are now implemented for fixed sized
  arrays of any length.][74989]
- [On Unix platforms, the `std::fs::File` type now has a "niche"
  of `-1`.][74699] This value cannot be a valid file descriptor,
  and now means `Option<File>` takes up the same amount of space
  as `File`.

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

- [`bool::then`]
- [`btree_map::Entry::or_insert_with_key`]
- [`f32::clamp`]
- [`f64::clamp`]
- [`hash_map::Entry::or_insert_with_key`]
- [`Ord::clamp`]
- [`RefCell::take`]
- [`slice::fill`]
- [`UnsafeCell::get_mut`]

The following previously stable methods are now `const`.

- [`IpAddr::is_ipv4`]
- [`IpAddr::is_ipv6`]
- [`Layout::size`]
- [`Layout::align`]
- [`Layout::from_size_align`]
- `pow` for all integer types.
- `checked_pow` for all integer types.
- `saturating_pow` for all integer types.
- `wrapping_pow` for all integer types.
- `next_power_of_two` for all unsigned integer types.
- `checked_power_of_two` for all unsigned integer types.

Cargo
-----------------------

- [Added the `[build.rustc-workspace-wrapper]` option.][cargo/8976]
  This option sets a wrapper to execute instead of `rustc`, for
  workspace members only.
- [`cargo:rerun-if-changed` will now, if provided a directory, scan the entire
  contents of that directory for changes.][cargo/8973]
- [Added the `--workspace` flag to the `cargo update` command.][cargo/8725]

Misc
----

- [The search results tab and the help button are focusable with
  keyboard in rustdoc.][79896]
- [Running tests will now print the total time taken to execute.][75752]

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

- [The `compare_and_swap` method on atomics has been deprecated.][79261]
  It's recommended to use the `compare_exchange` and
  `compare_exchange_weak` methods instead.
- [Changes in how `TokenStream`s are checked have fixed some cases
  where you could write unhygenic `macro_rules!` macros.][79472]
- [`#![test]` as an inner attribute is now considered unstable like
  other inner macro attributes, and reports an error by default
  through the `soft_unstable` lint.][79003]
- [Overriding a `forbid` lint at the same level that it was set is
  now a hard error.][78864]
- [Dropped support for all cloudabi targets.][78439]
- [You can no longer intercept `panic!` calls by supplying your
  own macro.][78343] It's recommended to use the `#[panic_handler]`
  attribute to provide your own implementation.
- [Semi-colons after item statements (e.g. `struct Foo {};`) now
  produce a warning.][78296]

rust: Update to version 1.45.2.

While here clean up all pkglint warnings.  Changes since 1.44.1:

Version 1.45.2 (2020-08-03)
==========================

* [Fix bindings in tuple struct patterns][74954]
* [Fix track_caller integration with trait objects][74784]

[74954]: https://github.com/rust-lang/rust/issues/74954
[74784]: https://github.com/rust-lang/rust/issues/74784

Version 1.45.1 (2020-07-30)
==========================

* [Fix const propagation with references.][73613]
* [rustfmt accepts rustfmt_skip in cfg_attr again.][73078]
* [Avoid spurious implicit region bound.][74509]
* [Install clippy on x.py install][74457]

[73078]: https://github.com/rust-lang/rust/issues/73078
[74509]: https://github.com/rust-lang/rust/pull/74509
[74457]: https://github.com/rust-lang/rust/pull/74457

Version 1.45.0 (2020-07-16)
==========================

Language
--------
- [Out of range float to int conversions using `as` has been defined as a saturating
  conversion.][71269] This was previously undefined behaviour, but you can use the
   `{f64, f32}::to_int_unchecked` methods to continue using the current behaviour, which
   may be desirable in rare performance sensitive situations.
- [`mem::Discriminant<T>` now uses `T`'s discriminant type instead of always
  using `u64`.][70705]
- [Function like procedural macros can now be used in expression, pattern, and  statement
  positions.][68717] This means you can now use a function-like procedural macro
  anywhere you can use a declarative (`macro_rules!`) macro.

Compiler
--------
- [You can now override individual target features through the `target-feature`
  flag.][72094] E.g. `-C target-feature=+avx2 -C target-feature=+fma` is now
  equivalent to `-C target-feature=+avx2,+fma`.
- [Added the `force-unwind-tables` flag.][69984] This option allows
  rustc to always generate unwind tables regardless of panic strategy.
- [Added the `embed-bitcode` flag.][71716] This codegen flag allows rustc
  to include LLVM bitcode into generated `rlib`s (this is on by default).
- [Added the `tiny` value to the `code-model` codegen flag.][72397]
- [Added tier 3 support\* for the `mipsel-sony-psp` target.][72062]
- [Added tier 3 support for the `thumbv7a-uwp-windows-msvc` target.][72133]

\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.


Libraries
---------
- [`net::{SocketAddr, SocketAddrV4, SocketAddrV6}` now implements `PartialOrd`
  and `Ord`.][72239]
- [`proc_macro::TokenStream` now implements `Default`.][72234]
- [You can now use `char` with
  `ops::{Range, RangeFrom, RangeFull, RangeInclusive, RangeTo}` to iterate over
  a range of codepoints.][72413] E.g.
  you can now write the following;
  ```rust
  for ch in 'a'..='z' {
      print!("{}", ch);
  }
  println!();
  // Prints "abcdefghijklmnopqrstuvwxyz"
  ```
- [`OsString` now implements `FromStr`.][71662]
- [The `saturating_neg` method as been added to all signed integer primitive
  types, and the `saturating_abs` method has been added for all integer
  primitive types.][71886]
- [`Arc<T>`, `Rc<T>` now implement  `From<Cow<'_, T>>`, and `Box` now
  implements `From<Cow>` when `T` is `[T: Copy]`, `str`, `CStr`, `OsStr`,
  or `Path`.][71447]
- [`Box<[T]>` now implements `From<[T; N]>`.][71095]
- [`BitOr` and `BitOrAssign` are implemented for all `NonZero`
  integer types.][69813]
- [The `fetch_min`, and `fetch_max` methods have been added to all atomic
  integer types.][72324]
- [The `fetch_update` method has been added to all atomic integer types.][71843]

Stabilized APIs
---------------
- [`Arc::as_ptr`]
- [`BTreeMap::remove_entry`]
- [`Rc::as_ptr`]
- [`rc::Weak::as_ptr`]
- [`rc::Weak::from_raw`]
- [`rc::Weak::into_raw`]
- [`str::strip_prefix`]
- [`str::strip_suffix`]
- [`sync::Weak::as_ptr`]
- [`sync::Weak::from_raw`]
- [`sync::Weak::into_raw`]
- [`char::UNICODE_VERSION`]
- [`Span::resolved_at`]
- [`Span::located_at`]
- [`Span::mixed_site`]
- [`unix::process::CommandExt::arg0`]

Cargo
-----

Misc
----
- [Rustdoc now supports strikethrough text in Markdown.][71928] E.g.
  `~~outdated information~~` becomes "~~outdated information~~".
- [Added an emoji to Rustdoc's deprecated API message.][72014]

Compatibility Notes
-------------------
- [Trying to self initialize a static value (that is creating a value using
  itself) is unsound and now causes a compile error.][71140]
- [`{f32, f64}::powi` now returns a slightly different value on Windows.][73420]
  This is due to changes in LLVM's intrinsics which `{f32, f64}::powi` uses.
- [Rustdoc's CLI's extra error exit codes have been removed.][71900] These were
  previously undocumented and not intended for public use. Rustdoc still provides
  a non-zero exit code on errors.

Internals Only
--------------
- [Make clippy a git subtree instead of a git submodule][70655]
- [Unify the undo log of all snapshot types][69464]
