lang/rust: update to version 1.81.0, taken from pkgsrc-wip.
Pkgsrc changes:
* Adapt patches, apply to new vendored crates where needed.
* Back-port rust pull request 130110, "make dist vendoring configurable"
* Disable "dist vendoring", otherwise cargo would try to access
the network during the build phase.

support has been deprecated for four years and was removed in
1.75.0.] (https://github.com/rust-lang/cargo/pull/13902/)
Compatibility Notes
-------------------
* Usage of the `wasm32-wasi` target will now issue a compiler
warning and request users switch to the `wasm32-wasip1` target
instead. Both targets are the same, `wasm32-wasi` is only being
renamed, and this [change to the WASI target]
(https://blog.rust-lang.org/2024/04/09/updates-to-rusts-wasi-targets.html)
is being done to enable removing `wasm32-wasi` in January 2025.
* We have renamed `std::panic::PanicInfo` to `std::panic::PanicHookInfo`.
The old name will continue to work as an alias, but will result in
a deprecation warning starting in Rust 1.82.0.
`core::panic::PanicInfo` will remain unchanged, however, as this
is now a *different type*.
The reason is that these types have different roles:
`std::panic::PanicHookInfo` is the argument to the [panic
hook](https://doc.rust-lang.org/stable/std/panic/fn.set_hook.html)
in std context (where panics can have an arbitrary payload),
while `core::panic::PanicInfo` is the argument to the
[`#[panic_handler]`](https://doc.rust-lang.org/nomicon/panic-handler.html)
in no_std context (where panics always carry a formatted *message*).
Separating these types allows us to add more useful methods to
these types, such as `std::panic::PanicHookInfo::payload_as_str()`
and `core::panic::PanicInfo::message()`.
* The new sort implementations may panic if a type's implementation
of [`Ord`](https://doc.rust-lang.org/std/cmp/trait.Ord.html) (or
the given comparison function) does not implement a [total
order](https://en.wikipedia.org/wiki/Total_order) as the trait
requires. `Ord`'s supertraits (`PartialOrd`, `Eq`, and `PartialEq`)
must also be consistent. The previous implementations would not
"notice" any problem, but the new implementations have a good chance
of detecting inconsistencies, throwing a panic rather than returning
knowingly unsorted data.
* [In very rare cases, a change in the internal evaluation order of the trait
solver may result in new fatal overflow errors.]
(https://github.com/rust-lang/rust/pull/126128)
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.
- [Add a Rust-for Linux `auto` CI job to check kernel builds.]
(https://github.com/rust-lang/rust/pull/125209/)
*: recursive bump for icu 76 shlib major version bump
*: revbump for icu downgrade
*: recursive bump for icu 76.1 shlib bump
lang/rust: update to version 1.80.1.
This is based on the pkgsrc-wip rust180 package, retaining
the main pkgsrc changes as best as I could.
Pkgsrc changes:
* Adapt checksums and patches.
* Make this work again on big-endian aarch64 (at least on NetBSD).
* Make the choice of GCC = 12 work for sparc64 by testing options
after options.mk is included (which is required...). Makes this
work on NetBSD/sparc64 10.0 again.

lang/rust: Update comment about which NetBSD versions this is for. Also extend pattern coverage and remove now-redundant entries.
lang/rust: pull over fixes to rust 1.79 from pkgsrc-wip: 1) Turn off the use ot thread local storage on NetBSD/aarch64, due to NetBSD PR#58154 and our desire to support systems built before the fix was applied. 2) Use the fixed 1.78.0 bootstrap for NetBSD/aarch64 (which is now built with the workaround from #1 applied). 3) Reinstate the patches to the openssl-sys and openssl-src vendor crates, and their checksum fixes, taken from pkgsrc-wip rust 1.78.0 and adapted. 4) Make the NetBSD/sparc64 target spec more similar to the other sparc64 targets. Does not resolve the cross-build problem, sadly.
rust: un-revert Makefile r1.308 I will sync the diffs to wip because apparently this package gets blindly overwritten with whatever is in wip and changes get lost.

revbump after icu and protobuf updates
*: recursive bump for gnutls p11-kit option (existing installations need the bl3.mk included, but it's now only optionally included)
rust: Bump illumos bootstrap kit. I don't know why this wasn't done with the package update, the bootstrap kit has been available for ages.
rust: add CHECK_PORTABILITY skip and use wildcard for ci scripts
lang/rust: revision bump for llvm update
rust: Revert part of last update to fix lib names.
lang/rust: update to 1.76.0
Language
- Document Rust ABI compatibility between various types
- Also: guarantee that char and u32 are ABI-compatible
- Add lint ambiguous_wide_pointer_comparisons that supersedes clippy::vtable_address_comparisons
Compiler
- Lint pinned #[must_use] pointers (in particular, Box<T> where T is #[must_use]) in unused_must_use.
- Soundness fix: fix computing the offset of an unsized field in a packed struct
- Soundness fix: fix dynamic size/align computation logic for packed types with dyn Trait tail
- Add $message_type field to distinguish json diagnostic outputs
- Enable Rust to use the EHCont security feature of Windows
- Add tier 3 {x86_64,i686}-win7-windows-msvc targets
- Add tier 3 aarch64-apple-watchos target
- Add tier 3 arm64e-apple-ios & arm64e-apple-darwin targets
Refer to Rust's platform support page for more information on Rust's tiered platform support.
Libraries
- Add a column number to dbg!()
- Add std::hash::{DefaultHasher, RandomState} exports
- Fix rounding issue with exponents in fmt
- Add T: ?Sized to RwLockReadGuard and RwLockWriteGuard's Debug impls.
- Windows: Allow File::create to work on hidden files

Cargo
See Cargo release notes.
Rustdoc
- Don't merge cfg and doc(cfg) attributes for re-exports
- rustdoc: allow resizing the sidebar / hiding the top bar
- rustdoc-search: add support for traits and associated types
- rustdoc: Add highlighting for comments in items declaration
Compatibility Notes
- Add allow-by-default lint for unit bindings This is expected to be upgraded to a warning by default in a future Rust release. Some macros emit bindings with type () with user-provided spans, which means that this lint will warn for user code.
- Remove x86_64-sun-solaris target.
- Remove asmjs-unknown-emscripten target
- Report errors in jobserver inherited through environment variables This may warn on benign problems too.
- Update the minimum external LLVM to 16.
- Improve print_tts This change can break some naive manual parsing of token trees in proc macro code which expect a particular structure after .to_string(), rather than just arbitrary Rust code.
- Make IMPLIED_BOUNDS_ENTAILMENT into a hard error from a lint
- Vec's allocation behavior was changed when collecting some iterators Allocation behavior is currently not specified, nevertheless changes can be surprising. See impl FromIterator for Vec for more details.
- Properly reject default on free const items
lang/rust: Need cmake as tool, not as buildlink.
rust: Upgrade to version 1.75.0.
Pkgsrc changes:
* Adjust patches and cargo checksums to new versions.
* For an external LLVM, set dependency of llvm >= 16, in accordance
with the upstream changes.
* Mark that on NetBSD we now need >= 9.0, so 8.x is no longer supported.
* On NetBSD/sparc64 10.x, we now need GCC 12 to build the embedded
LLVM, which is version 17; apparently GCC 10.4 or 10.5 mis-compiles it,
resulting in an illegal instruction fault during the build.

rust: Update illumos pkgsrc bootstrap libraries.
lang/rust: remove references to build-time DESTDIR When the package is installed, the temporary DESTDIR directory doesn't exist anymore, so there's no point referring to it. Bump PKGREVISION.
rust: add a CHECK_PORTABILITY_SKIP
rust: update to version 1.74.1.
Pkgsrc changes:
* Remove NetBSD-8 support (embedded LLVm requires newer C++
than what is in -8; it's conceivable that this could still
build with an external LLVM)
* undo powerpc 9.0 file naming tweak, since we no longer support -8.
* Remove patch to LLVM for powerpc now included by upstream.
* Minor adjustments, checksum changes etc.

v1.72.1
Changes
- Adjust codegen change to improve LLVM codegen
- rustdoc: Fix self ty params in objects with lifetimes
- Fix regression in compile times
- Resolve some ICE regressions in the compiler:
- #115215
- #115559
v1.72.0
Language
- Replace const eval limit by a lint and add an exponential backoff warning
- expand: Change how #![cfg(FALSE)] behaves on crate root
- Stabilize inline asm for LoongArch64
- Uplift clippy::undropped_manually_drops lint
- Uplift clippy::invalid_utf8_in_unchecked lint as invalid_from_utf8_unchecked
and invalid_from_utf8
- Uplift clippy::cast_ref_to_mut lint as invalid_reference_casting
- Uplift clippy::cmp_nan lint as invalid_nan_comparisons
- resolve: Remove artificial import ambiguity errors
- Don’t require associated types with Self: Sized bounds in dyn Trait objects
Compiler
- Remember names of cfg-ed out items to mention them in diagnostics
- Support for native WASM exceptions
- Add support for NetBSD/aarch64-be (big-endian arm64).
- Write to stdout if - is given as output file
- Force all native libraries to be statically linked when linking a static
binary
- Add Tier 3 support for loongarch64-unknown-none*
- Prevent .eh_frame from being emitted for -C panic=abort
- Support 128-bit enum variant in debuginfo codegen
- compiler: update solaris/illumos to enable tsan support.
Refer to Rust’s platform support page, platform-support-doc for more
information on Rust’s tiered platform support.
Libraries
- Document memory orderings of thread::{park, unpark}
- io: soften ‘at most one write attempt’ requirement in io::Write::write
- Specify behavior of HashSet::insert

Stabilized APIs
impl<T: Send> Sync for mpsc::Sender<T>
impl TryFrom<&OsStr> for &str
String::leak
These APIs are now stable in const contexts:
CStr::from_bytes_with_nul
CStr::to_bytes
CStr::to_bytes_with_nul
CStr::to_str
Cargo
- Enable -Zdoctest-in-workspace by default. When running each documentation
test, the working directory is set to the root directory of the package the
test belongs to. docs #12221 #12288
- Add support of the “default” keyword to reset previously set build.jobs
parallelism back to the default. #12222
Compatibility Notes
- Alter Display for Ipv6Addr for IPv4-compatible addresses
- Cargo changed feature name validation check to a hard error. The warning was
added in Rust 1.49. These extended characters aren’t allowed on crates.io,
so this should only impact users of other registries, or people who don’t
publish to a registry. #12291
- Demoted mips*-unknown-linux-gnu* targets from host tier 2 to target tier 3 support.
*: bump for openssl 3
rust: Add forgotten illumos bootstrap bump. Note that while updating the checksum, I noticed that the NetBSD/i586 bootstrap kits had changed too, so it's possible they are currently broken.
lang/rust: restore USE_CXX_FEATURES lost during the last update.
lang/rust: update to 1.71.1
Packaged by he@ and adam@ in wip
Merge request by gdt@
v1.71.1
- Fix CVE-2023-38497: Cargo did not respect the umask when extracting
dependencies
- Fix bash completion for users of Rustup
- Do not show suspicious_double_ref_op lint when calling borrow()
- Fix ICE: substitute types before checking inlining compatibility
- Fix ICE: don't use can_eq in derive(..) suggestion for missing method
- Fix building Rust 1.71.0 from the source tarball
v1.71.0
Language
- Stabilize raw-dylib, link_ordinal, import_name_type and -Cdlltool.
- Uplift clippy::{drop,forget}_{ref,copy} lints.
- Type inference is more conservative around constrained vars.
- Use fulfillment to check Drop impl compatibility
Compiler
- Evaluate place expression in PlaceMention, making let _ = patterns more
consistent with respect to the borrow checker.
- Add --print deployment-target flag for Apple targets.
- Stabilize extern "C-unwind" and friends. The existing extern "C" etc. may
change behavior for cross-language unwinding in a future release.
- Update the version of musl used on *-linux-musl targets to 1.2.3, enabling
time64 on 32-bit systems.
- Stabilize debugger_visualizer for embedding metadata like Microsoft's Natvis.
- Enable flatten-format-args by default.
- Make Self respect tuple constructor privacy.
- Improve niche placement by trying two strategies and picking the better
result.
- Use apple-m1 as the target CPU for aarch64-apple-darwin.
- Add Tier 3 support for the x86_64h-apple-darwin target.
- Promote loongarch64-unknown-linux-gnu to Tier 2 with host tools.
Refer to Rust's platform support page for more information on Rust's tiered
platform support.
Libraries
- Rework handling of recursive panics. Additional panics are allowed while
unwinding, as long as they are caught before escaping a Drop implementation,
but panicking within a panic hook is now an immediate abort.
- Loosen From<&[T]> for Box<[T]> bound to T: Clone.
- Remove unnecessary T: Send bound in Error for mpsc::SendError<T> and
TrySendError<T>.
- Fix docs for alloc::realloc to match Layout requirements that the size must
not exceed isize::MAX.
- Document const {} syntax for std::thread_local. This syntax was stabilized
in Rust 1.59, but not previously mentioned in release notes.

Cargo
- Allow named debuginfo options in Cargo.toml.
- Add workspace_default_members to the output of cargo metadata.
- Automatically inherit workspace fields when running cargo new/cargo init.
Rustdoc
- Add a new rustdoc::unescaped_backticks lint for broken inline code.
- Support strikethrough with single tildes. (~~old~~ vs. ~new~)
Compatibility Notes
- Remove structural match from TypeId. Code that uses a constant TypeId in a
pattern will potentially be broken. Known cases have already been fixed
-- in particular, users of the log crate's kv_unstable feature should update
to log v0.4.18 or later.
- Add a sysroot crate to represent the standard library crates. This does not
affect stable users, but may require adjustment in tools that build their
own standard library.
- Cargo optimizes its usage under rustup. When Cargo detects it will run rustc
pointing to a rustup proxy, it'll try bypassing the proxy and use the
underlying binary directly. There are assumptions around the interaction
with rustup and RUSTUP_TOOLCHAIN. However, it's not expected to affect
normal users.
- When querying a package, Cargo tries only the original name, all hyphens,
and all underscores to handle misspellings. Previously, Cargo tried each
combination of hyphens and underscores, causing excessive requests to
crates.io.
- Cargo now disallows RUSTUP_HOME and RUSTUP_TOOLCHAIN in the [env]
configuration table. This is considered to be not a use case Cargo would
like to support, since it will likely cause problems or lead to confusion.
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.
*: recursive bump for Python 3.11 as new default
lang: Adapt packages to USE_(CC|CXX)_FEATURES where possible
rust: Upgrade to version 1.70.0.
Pkgsrc changes:
* Adjust patches and cargo checksums to new versions.
* Add support for NetBSD/riscv64.
Upstream changes:
Version 1.70.0 (2023-06-01)
==========================
Language
--------
- [Relax ordering rules for `asm!` operands]
(https://github.com/rust-lang/rust/pull/105798/)
- [Properly allow macro expanded `format_args` invocations to uses captures]
(https://github.com/rust-lang/rust/pull/106505/)
- [Lint ambiguous glob re-exports]
(https://github.com/rust-lang/rust/pull/107880/)
- [Perform const and unsafe checking for expressions in `let _ =
expr` position.]
(https://github.com/rust-lang/rust/pull/102256/)
Compiler
--------
- [Extend -Cdebuginfo with new options and named aliases]
(https://github.com/rust-lang/rust/pull/109808/)
This provides a smaller version of debuginfo for cases that only
need line number information (`-Cdebuginfo=line-tables-only`),
which may eventually become the default for `-Cdebuginfo=1`.
- [Make `unused_allocation` lint against `Box::new` too]
(https://github.com/rust-lang/rust/pull/104363/)
- [Detect uninhabited types early in const eval]
(https://github.com/rust-lang/rust/pull/109435/)
- [Switch to LLD as default linker for {arm,thumb}v4t-none-eabi]
(https://github.com/rust-lang/rust/pull/109721/)
- [Add tier 3 target `loongarch64-unknown-linux-gnu`]
(https://github.com/rust-lang/rust/pull/96971)
- [Add tier 3 target for `i586-pc-nto-qnx700`(QNX Neutrino RTOS, version 7.0)]
(https://github.com/rust-lang/rust/pull/109173/),
- [Insert alignment checks for pointer dereferences as debug assertions]
(https://github.com/rust-lang/rust/pull/98112)
This catches undefined behavior at runtime, and may cause existing
code to fail.
Refer to Rust's [platform support page][platform-support-doc]
for more information on Rust's tiered platform support.

(https://github.com/rust-lang/rust/pull/105587/)
- [Stabilize `nonzero_min_max`]
(https://github.com/rust-lang/rust/pull/106633/)
- [Flatten/inline format_args!() and (string and int) literal
arguments into format_args!()]
(https://github.com/rust-lang/rust/pull/106824/)
- [Stabilize movbe target feature]
(https://github.com/rust-lang/rust/pull/107711/)
- [don't splice from files into pipes in io::copy]
(https://github.com/rust-lang/rust/pull/108283/)
- [Add a builtin unstable `FnPtr` trait that is implemented for
all function pointers]
(https://github.com/rust-lang/rust/pull/108080/)
This extends `Debug`, `Pointer`, `Hash`, `PartialEq`, `Eq`,
`PartialOrd`, and `Ord` implementations for function pointers
with all ABIs.

rust: fix build on Darwin if Homebrew is installed The openssl-sys crate has a misguided piece of logic to prefer any Homebrew tree to the usual place for finding OpenSSL. Remove this code so that Rust actually uses pkgsrc OpenSSL as it should. In particular, if you have Apple Game Porting toolkit installed, you get a Homebrew installation for x86_64 on an ARM machine, which can never work. OK during freeze adam@, wiz@
Mass-change BUILD_DEPENDS to TOOL_DEPENDS outside mk/. Almost all uses, if not all of them, are wrong, according to the semantics of BUILD_DEPENDS (packages built for target available for use _by_ tools at build-time) and TOOL_DEPEPNDS (packages built for host available for use _as_ tools at build-time).

revbump after textproc/icu update
rust: Update illumos bootstrap.
rust: Upgrade to version 1.68.2.
Pkgsrc changes:
* Adjust patches (add & remove) and cargo checksums to new versions.
* It's conceivable that the workaround for LLVM based NetBSD works
even less in this version (ref. PKGSRC_HAVE_LIBCPP not having a
corresponding patch anymore).
Upstream changes:
Version 1.68.2 (2023-03-28)
===========================
- [Update the GitHub RSA host key bundled within Cargo]
(https://github.com/rust-lang/cargo/pull/11883).
The key was [rotated by GitHub]
(https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/)
on 2023-03-24 after the old one leaked.
- [Mark the old GitHub RSA host key as revoked]
(https://github.com/rust-lang/cargo/pull/11889).
This will prevent Cargo from accepting the leaked key even when
trusted by the system.
- [Add support for `@revoked` and a better error message for
`@cert-authority` in Cargo's SSH host key verification]
(https://github.com/rust-lang/cargo/pull/11635)
Version 1.68.1 (2023-03-23)
===========================
- [Fix miscompilation in produced Windows MSVC artifacts]
(https://github.com/rust-lang/rust/pull/109094)
This was introduced by enabling ThinLTO for the distributed rustc
which led to miscompilations in the resulting binary. Currently
this is believed to be limited to the -Zdylib-lto flag used for
rustc compilation, rather than a general bug in ThinLTO, so only
rustc artifacts should be affected.
- [Fix --enable-local-rust builds]
(https://github.com/rust-lang/rust/pull/109111/)
- [Treat `$prefix-clang` as `clang` in linker detection code]
(https://github.com/rust-lang/rust/pull/109156)
- [Fix panic in compiler code]
(https://github.com/rust-lang/rust/pull/108162)

Compatibility Notes
-------------------
- [The layout of `repr(Rust)` types now groups m\*2^n-sized fields
with equivalently aligned ones.]
(https://github.com/rust-lang/rust/pull/102750/) This is intended
to be an optimization, but it is also known to increase type
sizes in a few cases for the placement of enum tags. As a reminder,
the layout of `repr(Rust)` types is an implementation detail,
subject to change.
- [0.5 now rounds to 0 when formatted to 0 decimal places.]
(https://github.com/rust-lang/rust/pull/102935/)
This makes it consistent with the rest of floating point formatting that
rounds ties toward even digits.
- [Chains of `&&` and `||` will now drop temporaries from their
sub-expressions in evaluation order, left-to-right.]
(https://github.com/rust-lang/rust/pull/103293/) Previously, it
was "twisted" such that the _first_ expression dropped its
temporaries _last_, after all of the other expressions dropped
in order.
- [Underscore suffixes on string literals are now a hard error.]
(https://github.com/rust-lang/rust/pull/103914/)
This has been a future-compatibility warning since 1.20.0.
- [Stop passing `-export-dynamic` to `wasm-ld`.]
(https://github.com/rust-lang/rust/pull/105405/)
- [`main` is now mangled as `__main_void` on `wasm32-wasi`.]
(https://github.com/rust-lang/rust/pull/105468/)

the configuration with the same index URL.]

(lang/rust) MAKE_JOBS_SAFE?= yes for NetBSD/9.1 .. 9.8
rust: Upgrade to version 1.66.1.
Pkgsrc changes:
* pkglint cleanups, bump bootstrap kits to 1.65.0.
* New target: mipsel-unknown-netbsd, for cpu=mips32 with soft-float.
* Managed to retain the build of aarch64_be, llvm needed a patch to
avoid use of neon instructions in the BE case (llvm doesn't support
use of neon in BE mode). Ref. patch to
src/llvm-project/llvm/lib/Support/BLAKE3/blake3_impl.h.
Also submitted upstream of LLVM to the BLAKE3 maintainers.
* The minimum gcc version is now 7.x, and that includes the
cross-compiler for the targets. For i386 this also needs to
/usr/include/gcc-7 include files in the target root, because
immintrin.h from gcc 5 is not compatible with gcc 7.x. This
applies for the targets where we build against a root from netbsd-8
(sparc64, powerpc, i386), and files/gcc-wrap gets a hack for this.
* Pick up tweak for -latomic inclusion from
https://github.com/rust-lang/rust/issues/104220
and
https://github.com/rust-lang/rust/pull/104572
* Retain ability to do 32-bit NetBSD, by changing from 64 to 32 bit
types in library/std/src/sys/unix/thread_parker/netbsd.rs.
* I've tried to get the "openssl-src" build with -latomic where it's
needed. I've introduced the "NetBSD-generic32" system type and use
it for the NetBSD mipsel target. There is another attempt to do
the same in the patch to vendor/openssl-sys/build/main.rs.

This also changes the safety conditions on
`Layout::from_size_align_unchecked`.
Stabilized APIs
---------------
- [`std::backtrace::Backtrace`]
(https://doc.rust-lang.org/stable/std/backtrace/struct.Backtrace.html)
- [`Bound::as_ref`]
(https://doc.rust-lang.org/stable/std/ops/enum.Bound.html#method.as_ref)
- [`std::io::read_to_string`]
(https://doc.rust-lang.org/stable/std/io/fn.read_to_string.html)
- [`<*const T>::cast_mut`]
(https://doc.rust-lang.org/stable/std/primitive.pointer.html#method.cast_mut)
- [`<*mut T>::cast_const`]
(https://doc.rust-lang.org/stable/std/primitive.pointer.html#method.cast_const)
These APIs are now stable in const contexts:
- [`<*const T>::offset_from`]
(https://doc.rust-lang.org/stable/std/primitive.pointer.html#method.offset_from)
- [`<*mut T>::offset_from`]
(https://doc.rust-lang.org/stable/std/primitive.pointer.html#method.offset_from)
Cargo
-----
- [Apply GitHub fast path even for partial hashes]
(https://github.com/rust-lang/cargo/pull/10807/)
- [Do not add home bin path to PATH if it's already there]
(https://github.com/rust-lang/cargo/pull/11023/)
- [Take priority into account within the pending queue]
(https://github.com/rust-lang/cargo/pull/11032/).
This slightly optimizes job scheduling by Cargo, with typically
small improvements on larger crate graph builds.
Compatibility Notes
-------------------
- [`std::layout::Layout` size must not overflow `isize::MAX` when
rounded up to `align`] (https://github.com/rust-lang/rust/pull/95295).
This also changes the safety conditions on
`Layout::from_size_align_unchecked`.
- [`PollFn` now only implements `Unpin` if the closure is `Unpin`]
(https://github.com/rust-lang/rust/pull/102737).
This is a possible breaking change if users were relying on the
blanket unpin implementation. See discussion on the PR for
details of why this change was made.
- [Drop ExactSizeIterator impl from std::char::EscapeAscii]
(https://github.com/rust-lang/rust/pull/99880)
This is a backwards-incompatible change to the standard library's
surface area, but is unlikely to affect real world usage.
- [Do not consider a single repeated lifetime eligible for elision
in the return type] (https://github.com/rust-lang/rust/pull/103450)
This behavior was unintentionally changed in 1.64.0, and this
release reverts that change by making this an error again.
- [Reenable disabled early syntax gates as future-incompatibility
lints] (https://github.com/rust-lang/rust/pull/99935/)
- [Update the minimum external LLVM to 13]
(https://github.com/rust-lang/rust/pull/100460/)
- [Don't duplicate file descriptors into stdio fds]
(https://github.com/rust-lang/rust/pull/101426/)
- [Sunset RLS](https://github.com/rust-lang/rust/pull/100863/)
- [Deny usage of `#![cfg_attr(..., crate_type = ...)]` to set the
crate type] (https://github.com/rust-lang/rust/pull/99784/)
This strengthens the forward compatibility lint
deprecated_cfg_attr_crate_type_name to deny.
- [`llvm-has-rust-patches` allows setting the build system to treat
the LLVM as having Rust-specific patches]
(https://github.com/rust-lang/rust/pull/101072)
This option may need to be set for distributions that are building
Rust with a patched LLVM via `llvm-config`, not the built-in
LLVM.
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.
- [Add `x.sh` and `x.ps1` shell scripts]
(https://github.com/rust-lang/rust/pull/99992/)
- [compiletest: use target cfg instead of hard-coded tables]
(https://github.com/rust-lang/rust/pull/100260/)
- [Use object instead of LLVM for reading bitcode from rlibs]
(https://github.com/rust-lang/rust/pull/98100/)
- [Enable MIR inlining for optimized compilations]
(https://github.com/rust-lang/rust/pull/91743)
This provides a 3-10% improvement in compiletimes for real world
crates. See [perf results]
(https://perf.rust-lang.org/compare.html?start=aedf78e56b2279cc869962feac5153b6ba7001ed&end=0075bb4fad68e64b6d1be06bf2db366c30bc75e1&stat=instructions:u).
rust: Stop xz being buildlinked.
The recent xz update broke the API and rust happened to be using it via other
buildlink3 dependencies, even though we try to use the bundled version. Set
BUILDLINK_FILES_CMD.xz to ${TRUE} to avoid any xz files from being linked, and
ensuring we use the bundled copy.
rust: Force use of bundled lzma.
rust: explicitly conflict with rust-src and rust-analyzer Installed as part of rust-1.64
rust: update to version 1.64.0.
Pkgsrc changes:
* This package now contains rust-analyzer, so implicitly
conflicts with that pkgsrc package. The same goes for
the rust-src package.
* Add NetBSD/arm6 port
* Add unfinished NetBSD/mipsel port
* Revert the use of the internal LLVM,
should now build with the new pkgsrc LLVM (15).
* Add depndence on compat80 for sparc64 to fix the build
* Adapt patches
* Add CHECK_INTERPRETER_SKIP for a few (mostly unused) files.
(A proper fix may come later.)
Upstream changes:
Version 1.64.0 (2022-09-22)
===========================
Language
--------
- [Unions with mutable references or tuples of allowed types are
now allowed](https://github.com/rust-lang/rust/pull/97995/)

existing warning for unused struct fields. This lint will become
warn-by-default in the future.

Cargo
-----
- [Packages can now inherit settings from the workspace so that
the settings can be centralized in one place.]
(https://github.com/rust-lang/cargo/pull/10859) See
[`workspace.package`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacepackage-table)
and
[`workspace.dependencies`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-workspacedependencies-table)
for more details on how to define these common settings.
- [Cargo commands can now accept multiple `--target` flags to build
for multiple targets at once]
(https://github.com/rust-lang/cargo/pull/10766), and the
[`build.target`](https://doc.rust-lang.org/nightly/cargo/reference/config.html#buildtarget)
config option may now take an array of multiple targets.
- [The `--jobs` argument can now take a negative number to count
backwards from the max CPUs.]
(https://github.com/rust-lang/cargo/pull/10844)
- [`cargo add` will now update `Cargo.lock`.]
(https://github.com/rust-lang/cargo/pull/10902)

Misc
----
- [The `rust-analyzer` rustup component is now available on the stable channel.]
(https://github.com/rust-lang/rust/pull/98640/)
Compatibility Notes
-------------------
- The minimum required versions for all `-linux-gnu` targets are
now at least kernel 3.2 and glibc 2.17, for targets that previously
supported older versions: [Increase the minimum linux-gnu
versions](https://github.com/rust-lang/rust/pull/95026/)
- [Network primitives are now implemented with the ideal Rust
layout, not the C system layout]
(https://github.com/rust-lang/rust/pull/78802/). This can
cause problems when transmuting the types.
- [Add assertion that `transmute_copy`'s `U` is not larger than `T`]
(https://github.com/rust-lang/rust/pull/98839/)
- [A soundness bug in `BTreeMap` was fixed]
(https://github.com/rust-lang/rust/pull/99413/) that allowed data
it was borrowing to be dropped before the container.
- [The Drop behavior of C-like enums cast to ints has changed]
(https://github.com/rust-lang/rust/pull/96862/). These are already
discouraged by a compiler warning.
- [Relate late-bound closure lifetimes to parent fn in NLL]
(https://github.com/rust-lang/rust/pull/98835/)
- [Errors at const-eval time are now in future incompatibility reports]
(https://github.com/rust-lang/rust/pull/97743/)
- On the `thumbv6m-none-eabi` target, some incorrect `asm!` statements
were erroneously accepted if they used the high registers (r8 to
r14) as an input/output operand. [This is no longer accepted]
(https://github.com/rust-lang/rust/pull/99155/).
- [`impl Trait` was accidentally accepted as the associated type
value of return-position `impl Trait`]
(https://github.com/rust-lang/rust/pull/97346/), without
fulfilling all the trait bounds of that associated type, as long
as the hidden type satisfies said bounds. This has been fixed.
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.
- Windows builds now use profile-guided optimization, providing
10-20% improvements to compiler performance: [Utilize PGO for
windows x64 rustc dist builds]

rust: Cleanups and fixes from wip. No effective functional change to normal builds, primarily whitespace changes, but does include a fix to the stage0-bootstrap target.
lang/rust: update to version 1.62.1.
Pkgsrc changes:
* Bump required GCC to 7 (same as LLVM) to avoid ABI issues
Fixes native i386 and powerpc 8.x build w/pkgsrc LLVM 14
* Bump available bootstraps to 1.61.0.
* Also unlimit stacksize
* Sync patches over from wip/rust
* Adjust line number in patches which had non-zero offsets.
* no longer pass -I/usr/pkg/include through via gcc-wrap script
when building natively. Attempt at fixing version skew with curl
package vs. internal version of curl (may not work...)
* The NetBSD bootstraps now use .xz compression.
* Use mk/atomic64.mk. Still have conditional for libatomic-links.
* Default to using the internal LLVM when cross-building.
Upstream changes:
Version 1.62.1 (2022-07-19)
==========================
Rust 1.62.1 addresses a few recent regressions in the compiler and standard
library, and also mitigates a CPU vulnerability on Intel SGX.
* [The compiler fixed unsound function coercions involving `impl
Trait` return types.][98608]
* [The compiler fixed an incremental compilation bug with `async
fn` lifetimes.][98890]
* [Windows added a fallback for overlapped I/O in synchronous reads
and writes.][98950]
* [The `x86_64-fortanix-unknown-sgx` target added a mitigation for the
MMIO stale data vulnerability][98126], advisory [INTEL-SA-00615].

code pattern][96268]
Compiler
--------
- [linker: Stop using whole-archive on dependencies of dylibs][96436]
- [Make `unaligned_references` lint deny-by-default][95372]
This lint is also a future compatibility lint, and is expected to eventually
become a hard error.

Clippy
------
- [Create clippy lint against unexpectedly late drop for temporaries

Cargo
-----
- Added the `cargo add` command for adding dependencies to `Cargo.toml` from
the command-line.
[docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-add.html)
- Package ID specs now support `name@version` syntax in addition to the
previous `name:version` to align with the behavior in `cargo add` and other
tools. `cargo install` and `cargo yank` also now support this syntax so the
version does not need to passed as a separate flag.
- The `git` and `registry` directories in Cargo's home directory (usually
`~/.cargo`) are now marked as cache directories so that they are not
included in backups or content indexing (on Windows).
- Added automatic `@` argfile support, which will use "response files" if the
command-line to `rustc` exceeds the operating system's limit.
Compatibility Notes
-------------------
- `cargo test` now passes `--target` to `rustdoc` if the specified target is
the same as the host target.

- [rustdoc: Remove .woff font files][96279]
- [Enforce Copy bounds for repeat elements while considering lifetimes][95819]
Internal Changes
----------------
- [Unify ReentrantMutex implementations across all platforms][96042]
These changes provide no direct user facing benefits, but represent
significant improvements to the internals and overall performance
of rustc and related tools.

Version 1.61.0 (2022-05-19)
==========================
Language
--------
- [`const fn` signatures can now include generic trait bounds][93827]
- [`const fn` signatures can now use `impl Trait` in argument and return
position][93827]
- [Function pointers can now be created, cast, and passed around in a
`const fn`][93827]
- [Recursive calls can now set the value of a function's opaque
`impl Trait` return type][94081]
Compiler
--------
- [Linking modifier syntax in `#[link]` attributes and on the command
line, as well as the `whole-archive` modifier specifically, are now
supported][93901]
- [The `char` type is now described as UTF-32 in debuginfo][89887]
- The [`#[target_feature]`][target_feature] attribute
[can now be used with aarch64 features][90621]
- X86 [`#[target_feature = "adx"]` is now stable][93745]
Libraries
---------
- [`ManuallyDrop<T>` is now documented to have the same layout as `T`][88375]
- [`#[ignore = "#"]` messages are printed when running tests][92714]
- [Consistently show absent stdio handles on Windows as NULL handles][93263]
- [Make `std::io::stdio::lock()` return `'static` handles.][93965]
Previously, the creation of locked handles to stdin/stdout/stderr would
borrow the handles being locked, which prevented writing
`let out = std::io::stdout().lock();` because `out` would outlive
the return value of `stdout()`.
Such code now works, eliminating a common pitfall that affected many
Rust users.
- [`Vec::from_raw_parts` is now less restrictive about its inputs][95016]
- [`std::thread::available_parallelism` now takes cgroup quotas into
account.][92697] Since `available_parallelism` is often used to create a
thread pool for parallel computation, which may be CPU-bound for
performance, `available_parallelism` will return a value consistent with
the ability to use that many threads continuously, if possible.
For instance, in a container with 8 virtual CPUs but quotas only allowing
for 50% usage, `available_parallelism` will return 4.
Stabilized APIs
---------------
- [`Pin::static_mut`]
- [`Pin::static_ref`]
- [`Vec::retain_mut`]
- [`VecDeque::retain_mut`]
- [`Write` for `Cursor<[u8; N]>`][cursor-write-array]
- [`std::os::unix::net::SocketAddr::from_pathname`]
- [`std::process::ExitCode`] and [`std::process::Termination`].
The stabilization of these two API s now makes it possible for
programs to return errors from `main` with custom exit codes.

Compatibility Notes
-------------------
- Previously native static libraries were linked as `whole-archive` in
some cases, but now rustc tries not to use `whole-archive` unless
explicitly requested. This [change][93901] may result in linking errors
in some cases. To fix such errors, native libraries linked from the
command line, build scripts, or [`#[link]` attributes][link-attr] need to
- (more common) either be reordered to respect dependencies between them
(if `a` depends on `b` then `a` should go first and `b` second)
- (less common) or be updated to use the [`+whole-archive`] modifier.
- [Catching a second unwind from FFI code while cleaning up from a Rust
panic now causes the process to abort][92911]
- [Proc macros no longer see `ident` matchers wrapped in groups][92472]
- [The number of `#` in `r#` raw string literals is now required to be
less than 256][95251]
- [When checking that a dyn type satisfies a trait bound, supertrait
bounds are now enforced][92285]
- [`cargo vendor` now only accepts one value for each `--sync` flag]
[cargo/10448]
- [`cfg` predicates in `all()` and `any()` are always evaluated to detect
errors, instead of short-circuiting.][94295] The compatibility
considerations here arise in nightly-only code that used the
short-circuiting behavior of `all` to write something like
`cfg(all(feature = "nightly", syntax-requiring-nightly))`, which
will now fail to compile. Instead, use either `cfg_attr(feature
= "nightly", ...)` or nested uses of `cfg`.
- [bootstrap: static-libstdcpp is now enabled by default, and can
now be disabled when llvm-tools is enabled][94832]
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.
- [debuginfo: Refactor debuginfo generation for types][94261]

rust: clean up pre-build target Only needed for NetBSD i386, no need to copypasta it to all configurations. XXX is it even needed on i386? Bootstrap toolchain should ship with PaX settings if needed.
rust: Add ugly fix for incorrect flags on macOS/arm64. I've dug through the source code and removed loads of '-arch ' invocations but still can't find the one that is incorrectly adding '-arch x86_64', so for now we're just brute-force transforming it.
lang: Switch distfile location from Joyent to MNX Manta. No functional change.
*: recursive bump for perl 5.36
rust: Put back SunOS AR fix.
rust: Bump SunOS bootstrap and update target.
lang/rust: update to version 1.60.0.
Pkgsrc changes:
* Bump available bootstraps to 1.59.0.
* Adjust line number in patches which had non-zero offsets.

Compatibility Notes
-------------------
- [Remove compiler-rt linking hack on Android][83822]
- [Mitigations for platforms with non-monotonic clocks have been removed from
`Instant::now`][89926]. On platforms that don't provide monotonic clocks, an
instant is not guaranteed to be greater than an earlier instant anymore.
- [`Instant::{duration_since, elapsed, sub}` do not panic anymore on underflow,
saturating to `0` instead][89926]. In the real world the panic happened mostly
on platforms with buggy monotonic clock implementations rather than catching
programming errors like reversing the start and end times. Such programming
errors will now results in `0` rather than a panic.
- In a future release we're planning to increase the baseline requirements for
the Linux kernel to version 3.2, and for glibc to version 2.17. We'd love
your feedback in [PR #95026][95026].

rust: Use OPSYS_VERSION.
lang/rust: add patches so that RUST_BACKTRACE works. Add NetBSD to the systems which need dl_iterate_phdr(), and make NetBSD find the debug libraries if present. Also make the execinfo functions visible, but not sure that's used by rust. Back-ported from wip / 1.60.0, but we can't do != in conditionals here.
rust: future-proof by using OPSYS_VERSION for NetBSD
lang/rust: bump PKGREVISION after removal of PR#56791 workaround.
rust: build faster with one compression format
rust: update to version 1.59.0.
Pkgsrc changes:
* Bump available bootstraps to 1.58.1.
* Adjust one patch (and checksum) so that it still applies.
Upstream changes:
Version 1.59.0 (2022-02-24)
==========================
Language
--------
- [Stabilize default arguments for const generics][90207]
- [Stabilize destructuring assignment][90521]
- [Relax private in public lint on generic bounds and where clauses
of trait impls][90586]
- [Stabilize asm! and global_asm! for x86, x86_64, ARM, Aarch64,
and RISC-V][91728]
Compiler
--------
- [Stabilize new symbol mangling format, leaving it opt-in
(-Csymbol-mangling-version=v0)][90128]
- [Emit LLVM optimization remarks when enabled with `-Cremark`][90833]
- [Fix sparc64 ABI for aggregates with floating point members][91003]
- [Warn when a `#[test]`-like built-in attribute macro is present
multiple times.][91172]
- [Add support for riscv64gc-unknown-freebsd][91284]
- [Stabilize `-Z emit-future-incompat` as `--json future-incompat`][91535]
- [Soft disable incremental compilation][94124]
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 a known and relatively frequently occurring bug in incremental
compilation, which causes builds to issue internal compiler errors. This
particular bug is already fixed on nightly, but that fix has not yet rolled out
to stable and is deemed too risky for a direct stable backport.
As always, we encourage users to test with nightly and report bugs so that we
can track failures and fix issues earlier.
See [94124] for more details.

Compatibility Notes
-------------------
- [Refactor weak symbols in std::sys::unix][90846]
This may add new, versioned, symbols when building with a newer glibc, as the
standard library uses weak linkage rather than dynamically attempting to load
certain symbols at runtime.
- [Deprecate crate_type and crate_name nested inside `#![cfg_attr]`][83744]
This adds a future compatibility lint to supporting the use of cfg_attr
wrapping either crate_type or crate_name specification within Rust files;
it is recommended that users migrate to setting the equivalent command line
flags.
- [Remove effect of `#[no_link]` attribute on name resolution][92034]
This may expose new names, leading to conflicts with preexisting names in a
given namespace and a compilation failure.
- [Cargo will document libraries before binaries.][cargo/10172]
- [Respect doc=false in dependencies, not just the root crate][cargo/10201]
- [Weaken guarantee around advancing underlying iterators in zip][83791]
- [Make split_inclusive() on an empty slice yield an empty output][89825]
- [Update std::env::temp_dir to use GetTempPath2 on Windows when

- [unreachable! was updated to match other formatting macro behavior
on Rust 2021][92137]
Internal Changes
----------------

improvements to the internals and overall performance of rustc
and related tools.
- [Fix many cases of normalization-related ICEs][91255]
- [Replace dominators algorithm with simple Lengauer-Tarjan][85013]
- [Store liveness in interval sets for region inference][90637]

rust: Ensure SunOS uses GNU ar.
Update lang/rust to version 1.58.1.
Pkgsrc changes:
* Bump bootstrap kit version to 1.57.0.
* Bump require external LLVM to 12.0, according to upstream change log.
* Adjust patches as needed, adjust line numbers.
* Update checksum adjustments. For some reason the vendor/libc checksum
doesn't need fixing, apparently, it remains as commented out.
* Add makefile to do all the NetBSD boostrap/cross builds (do-cross.mk).
Allow passing in additions to CONFIGURE_ARGS via ADD_CONFIGURE_ARGS.
Upstream changes:
Version 1.58.1 (2022-01-19)
===========================
* Fix race condition in `std::fs::remove_dir_all` ([CVE-2022-21658])
* [Handle captured arguments in the `useless_format` Clippy lint][clippy/8295]
* [Move `non_send_fields_in_send_ty` Clippy lint to nursery][clippy/8075]
* [Fix wrong error message displayed when some imports are missing][91254]
* [Fix rustfmt not formatting generated files from stdin][92912]

Version 1.58.0 (2022-01-13)
==========================
Language
--------
- [Format strings can now capture arguments simply by writing
`{ident}` in the string.][90473] This works in all macros accepting
format strings. Support for this in `panic!` (`panic!("{ident}")`)
requires the 2021 edition; panic invocations in previous editions
that appear to be trying to use this will result in a warning lint
about not having the intended effect.
- [`*const T` pointers can now be dereferenced in const contexts.][89551]
- [The rules for when a generic struct implements `Unsize` have
been relaxed.][90417]
Compiler
--------
- [Add LLVM CFI support to the Rust compiler][89652]
- [Stabilize -Z strip as -C strip][90058]. Note that while release
builds already don't add debug symbols for the code you compile,
the compiled standard library that ships with Rust includes debug
symbols, so you may want to use the `strip` option to remove these
symbols to produce smaller release binaries. Note that this release
only includes support in rustc, not directly in cargo.
- [Add support for LLVM coverage mapping format versions 5 and 6][91207]
- [Emit LLVM optimization remarks when enabled with `-Cremark`][90833]
- [Update the minimum external LLVM to 12][90175]
- [Add `x86_64-unknown-none` at Tier 3*][89062]
- [Build musl dist artifacts with debuginfo enabled][90733]. When
building release binaries using musl, you may want to use the newly
stabilized strip option to remove these debug symbols, reducing
the size of your binaries.
- [Don't abort compilation after giving a lint error][87337]
- [Error messages point at the source of trait bound obligations
in more places][89580]
\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.
Libraries
---------
- [All remaining functions in the standard library have `#[must_use]`
annotations where appropriate][89692], producing a warning when
ignoring their return value. This helps catch mistakes such as
expecting a function to mutate a value in place rather than return
a new value.
- [Paths are automatically canonicalized on Windows for operations
that support it][89174]
- [Re-enable debug checks for `copy` and `copy_nonoverlapping`][90041]
- [Implement `RefUnwindSafe` for `Rc<T>`][87467]
- [Make RSplit<T, P>: Clone not require T: Clone][90117]
- [Implement `Termination` for `Result<Infallible, E>`][88601].
This allows writing `fn main() -> Result<Infallible, ErrorType>`,
for a program whose successful exits never involve returning from
`main` (for instance, a program that calls `exit`, or that uses
`exec` to run another program).
Stabilized APIs
---------------
- [`Metadata::is_symlink`]
- [`Path::is_symlink`]
- [`{integer}::saturating_div`]
- [`Option::unwrap_unchecked`]
- [`Result::unwrap_unchecked`]
- [`Result::unwrap_err_unchecked`]
- [`NonZero{unsigned}::is_power_of_two`]
- [`File::options`]
These APIs are now usable in const contexts:
- [`Duration::new`]
- [`Duration::checked_add`]
- [`Duration::saturating_add`]
- [`Duration::checked_sub`]
- [`Duration::saturating_sub`]
- [`Duration::checked_mul`]
- [`Duration::saturating_mul`]
- [`Duration::checked_div`]
- [`MaybeUninit::as_ptr`]
- [`MaybeUninit::as_mut_ptr`]
- [`MaybeUninit::assume_init`]
- [`MaybeUninit::assume_init_ref`]
Cargo
-----
- [Add --message-format for install command][cargo/10107]
- [Warn when alias shadows external subcommand][cargo/10082]
Rustdoc
-------
- [Show all Deref implementations recursively in rustdoc][90183]
- [Use computed visibility in rustdoc][88447]
Compatibility Notes
-------------------
- [Try all stable method candidates first before trying unstable
ones][90329]. This change ensures that adding new nightly-only
methods to the Rust standard library will not break code invoking
methods of the same name from traits outside the standard library.
- Windows: [`std::process::Command` will no longer search the
current directory for executables.][87704]
- [All proc-macro backward-compatibility lints are now deny-by-default.][88041]
- [proc_macro: Append .0 to unsuffixed float if it would otherwise
become int token][90297]
- [Refactor weak symbols in std::sys::unix][90846]. This optimizes
accesses to glibc functions, by avoiding the use of dlopen. This
does not increase the [minimum expected version of
glibc](https://doc.rust-lang.org/nightly/rustc/platform-support.html).
However, software distributions that use symbol versions to detect
library dependencies, and which take weak symbols into account in
that analysis, may detect rust binaries as requiring newer versions
of glibc.
- [rustdoc now rejects some unexpected semicolons in doctests][91026]
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.
- [Implement coherence checks for negative trait impls][90104]
- [Add rustc lint, warning when iterating over hashmaps][89558]
- [Optimize live point computation][90491]
- [Enable verification for 1/32nd of queries loaded from disk][90361]
- [Implement version of normalize_erasing_regions that allows for
normalization failure][91255]

Update lang/rust to version 1.57.0.
Pkgsrc changes:
* Adjust line numbers in a number of patches
* remove the --disable-dist-src option, so that we produce
the rust-src rust component, which we upload to LOCALSRC
to allow the rust-src package to build, which is needed
for rust-analyzer.
* Cargo checksum for vendor/cc no longer needs patching;
checksum for vendor/libc updated

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::_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]

revbump for boost-libs
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

- [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.

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]

- [`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.

rust: restore NetBSD i386 bootstrap workaround
The current i386 bootstrap is built for NetBSD 8.x, and so is linked
against libstdc++.so.8. NetBSD 9.x still requires compat80 for it to
run.
This isn't a complete workaround, as builds still fail in a sandboxed
environment that doesn't have compat80 installed outside it. Dealing
with that would require another workaround somewhat like the one used
for ghc*, but a little different.

Add another post-install dylib rpath fixup for macOS (libserde_derive). Bump PKGREVISION.
rust: add some more arm and aarch64 targets not tested, so not added to platforms.mk for now.
revbump for boost-libs
Fix errors and most warnings flagged by pkglint. Note to self: run pkglint before committing. Thanks to jperkin@ for the note.
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: normalize workarounds for cargo dependencies on NetBSD
Havard would like all rusts to be built with rust-cargo-static,
because this makes it easier to produce working bootstaps.
In order to do this, we need to handle the OpenSSL and curl
dependencies in older bootstrap kits properly.
This means, for the remaining bootstraps that do not yet have
cargo with static/vendored dependencies:
- depend on base 8.0 openssl (compat80) on i386.
- depend on pkgsrc curl on aarch64 and earmv7.
the armv7 bootstrap is built for 9.0 so does not need compat80.
the aarch64 bootstrap is built for 8.99.50 so does not need compat80.

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]

Further reduction of diffs with wip/rust/Makefile.
Remove reference to PR#54621, arm bootstrap requires NetBSD >= 9.0.
Reduce difference to wip/rust/: * Remove a few commented-out entries/settings * Add @PREFIX@ substitution to the netbsd_base.rs patch, and adjust patch accordingly.
Mark various NetBSD-8.* versions as broken, as the corresponding bootstrap is built for NetBSD-9.*.
rust: Fix SunOS bootstrap, sync from wip. Switch over to the illumos target and update to the latest, 1.46.0 is too old to build 1.48.0.
rust: Unbreak stage0-bootstrap target.
rust: Update checksum patch SUBST pattern to fix build
Upgrade rust to version 1.48.0.
Pkgsrc changes:
* Compensate for files being moved around upstream.
* Introduce optional, on-by-default semi-static building of cargo,
using the internal curl and openssl sources. This reduces the dynamic
dependencies of cargo and therefore the rust package itself.
Ref. options.mk.
* The 1.47.0 bootstrap kits have been re-built with the above option
turned on, so no longer depends on curl or openssl from pkgsrc and/or
from earlier OS or pkgsrc versions. This should hopefully fix
installation of rust with non-default PREFIX, ref. PR#54453.
Upstream changes:
Version 1.48.0 (2020-11-19)
==========================
Language
--------
- [The `unsafe` keyword is now syntactically permitted on modules.][75857] This
is still rejected *semantically*, but can now be parsed by procedural macros.
Compiler
--------
- [Stabilised the `-C link-self-contained=<yes|no>` compiler flag.][76158]
This tells `rustc` whether to link its own C runtime and libraries
or to rely on a external linker to find them. (Supported only on
`windows-gnu`, `linux-musl`, and `wasi` platforms.)
- [You can now use `-C target-feature=+crt-static` on `linux-gnu` targets.]
[77386]
Note: If you're using cargo you must explicitly pass the `--target` flag.
- [Added tier 2\* support for `aarch64-unknown-linux-musl`.][76420]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [`io::Write` is now implemented for `&ChildStdin` `&Sink`, `&Stdout`,
and `&Stderr`.][76275]
- [All arrays of any length now implement `TryFrom<Vec<T>>`.][76310]
- [The `matches!` macro now supports having a trailing comma.][74880]
- [`Vec<A>` now implements `PartialEq<[B]>` where `A: PartialEq<B>`.][74194]
- [The `RefCell::{replace, replace_with, clone}` methods now all use
`#[track_caller]`.][77055]
Stabilized APIs
---------------
- [`slice::as_ptr_range`]
- [`slice::as_mut_ptr_range`]
- [`VecDeque::make_contiguous`]
- [`future::pending`]
- [`future::ready`]
The following previously stable methods are now `const fn`'s:
- [`Option::is_some`]
- [`Option::is_none`]
- [`Option::as_ref`]
- [`Result::is_ok`]
- [`Result::is_err`]
- [`Result::as_ref`]
- [`Ordering::reverse`]
- [`Ordering::then`]
Cargo
-----
Rustdoc
-------
- [You can now link to items in `rustdoc` using the intra-doc link
syntax.][74430] E.g. ``/// Uses [`std::future`]`` will automatically generate
a link to `std::future`'s documentation. See ["Linking to items by
name"][intradoc-links] for more information.
- [You can now specify `#[doc(alias = "<alias>")]` on items to add
search aliases when searching through `rustdoc`'s UI.][75740]
Compatibility Notes
-------------------
- [Promotion of references to `'static` lifetime inside `const fn`
now follows the same rules as inside a `fn` body.][75502] In
particular, `&foo()` will not be promoted to `'static` lifetime
any more inside `const fn`s.
- [Associated type bindings on trait objects are now verified to meet the bounds
declared on the trait when checking that they implement the trait.][27675]
- [When trait bounds on associated types or opaque types are ambiguous, the
compiler no longer makes an arbitrary choice on which bound to use.][54121]
- [Fixed recursive nonterminals not being expanded in macros during
pretty-print/reparse check.][77153] This may cause errors if your macro wasn't
correctly handling recursive nonterminal tokens.
- [`&mut` references to non zero-sized types are no longer promoted.][75585]
- [`rustc` will now warn if you use attributes like `#[link_name]` or `#[cold]`
in places where they have no effect.][73461]
- [Updated `_mm256_extract_epi8` and `_mm256_extract_epi16` signatures in
`arch::{x86, x86_64}` to return `i32` to match the vendor signatures.][73166]
- [`mem::uninitialized` will now panic if any inner types inside
a struct or enum disallow zero-initialization.][71274]
- [`#[target_feature]` will now error if used in a place where it
has no effect.][78143]
- [Foreign exceptions are now caught by `catch_unwind` and will
cause an abort.][70212] Note: This behaviour is not guaranteed
and is still considered undefined behaviour, see the [`catch_unwind`]
documentation for further information.
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.
- [Building `rustc` from source now uses `ninja` by default over `make`.][74922]
You can continue building with `make` by setting `ninja=false` in
your `config.toml`.
- [cg_llvm: `fewer_names` in `uncached_llvm_type`][76030]
- [Made `ensure_sufficient_stack()` non-generic][76680]

Search /usr/pkg/lib/libatomic when linking. This is for the benefit of NetBSD/powerpc, where we now depends on the recently added libatomic-links package which leaves symlinks to the libatomic library files in that directory. This is so that we don't automatically pick up other libraries behind the compiler users back. Also, match the newly uploaded NetBSD/macppc 9.0 bootstrap (regenerated with this patch applied to 1.46.0). No pkgrevision bump, since this is a build fix for NetBSD/powerpc.
Put back ggrep instead of grep; my pkglint erroneously directed me there...
The patch which caused LLVM not to require 64-bit atomics is no more, so now we need -latomic on powerpc.
rust: Fix build with more checksum update
rust: update CKSUMS
Upgrade rust to version 1.47.0.
Pkgsrc changes:
* Remove patches now integrated upstream, many related to SunOS / Illumos.
* The LLVM fix for powerpc is also now integrated upstream.
* Adapt those patches where the source has moved or parts are integrated.
* The randomness patches no longer applies, and I could not find
where those files went...
* Provide a separate bootstrap for NetBSD/powerpc 9.0, since apparently
the C++ ABI is different from 8.0. Yes, this appears to be specific to
the NetBSD powerpc ports.
Upstream changes:
Version 1.47.0 (2020-10-08)
==========================
Language
--------
- [Closures will now warn when not used.][74869]

`is_ascii_control` methods for `char` and `u8`.][73858]
Cargo
-----
- [`build-dependencies` are now built with opt-level 0 by default.][cargo/8500]
You can override this by setting the following in your `Cargo.toml`.
```toml
[profile.release.build-override]
opt-level = 3
```
- [`cargo-help` will now display man pages for commands rather just the
`--help` text.][cargo/8456]

tests enabled.][cargo/8478]
- [`workspace.default-members` now respects `workspace.exclude`.][cargo/8485]
- [`cargo-publish` will now use an alternative registry by default if it's the
only registry specified in `package.publish`.][cargo/8571]

- [Fixed a regression parsing `{} && false` in tail expressions.][74650]
- [Added changes to how proc-macros are expanded in `macro_rules!` that should
help to preserve more span information.][73084] These changes may cause
compiliation errors if your macro was unhygenic or didn't correctly handle
`Delimiter::None`.
- [Moved support for the CloudABI target to tier 3.][75568]
- [`linux-gnu` targets now require minimum kernel 2.6.32 and glibc 2.11.][74163]
Internal Only
--------
- [Improved default settings for bootstrapping in `x.py`.][73964]
You can read details about this change in the ["Changes to `x.py`
defaults"](https://blog.rust-lang.org/inside-rust/2020/08/30/changes-to-x-py-defaults.html)
post on the Inside Rust blog.
- [Added the `rustc-docs` component.][75560] This allows you to install
and read the documentation for the compiler internal APIs. (Currently only
available for `x86_64-unknown-linux-gnu`.)

rust: Fix SUBST noop error
Pullup ticket #6329 (part 2) - requested by maya lang/rust: NetBSD 9 build fix (accidentally broken)
Further space-optimize when building natively on earmv7hf; only build llvm with the ARM CPU target, but when cross-building on X86, X86 needs to also be built, due to 2-stage build process.
Upgrade rust to version 1.46.0.
Pkgsrc changes:
* Portability patches for Illumos have been intregrated upstream,
so are no longer needed in pkgsrc.
* Adjust one other patch, and update vendor/libc cargo checksum.
Upstream changes:
Version 1.46.0 (2020-08-27)
==========================
Language
--------
- [`if`, `match`, and `loop` expressions can now be used in const functions.]
[72437]
- [Additionally you are now also able to coerce and cast to slices (`&[T]`) in
const functions.][73862]
- [The `#[track_caller]` attribute can now be added to functions to use the
function's caller's location information for panic messages.][72445]
- [Recursively indexing into tuples no longer needs parentheses.][71322] E.g.
`x.0.0` over `(x.0).0`.
- [`mem::transmute` can now be used in static and constants.][72920] **Note**
You currently can't use `mem::transmute` in constant functions.
Compiler
--------
- [You can now use the `cdylib` target on Apple iOS and tvOS platforms.][73516]
- [Enabled static "Position Independent Executables" by default
for `x86_64-unknown-linux-musl`.][70740]
Libraries
---------
- [`mem::forget` is now a `const fn`.][73887]
- [`String` now implements `From<char>`.][73466]
- [The `leading_ones`, and `trailing_ones` methods have been stabilised for all
integer types.][73032]
- [`vec::IntoIter<T>` now implements `AsRef<[T]>`.][72583]
- [All non-zero integer types (`NonZeroU8`) now implement `TryFrom` for their
zero-able equivalent (e.g. `TryFrom<u8>`).][72717]
- [`&[T]` and `&mut [T]` now implement `PartialEq<Vec<T>>`.][71660]
- [`(String, u16)` now implements `ToSocketAddrs`.][73007]
- [`vec::Drain<'_, T>` now implements `AsRef<[T]>`.][72584]
Stabilized APIs
---------------
- [`Option::zip`]
- [`vec::Drain::as_slice`]
Cargo
-----
Added a number of new environment variables that are now available when
compiling your crate.
- [`CARGO_BIN_NAME` and `CARGO_CRATE_NAME`][cargo/8270] Providing the name of
the specific binary being compiled and the name of the crate.
- [`CARGO_PKG_LICENSE`][cargo/8325] The license from the manifest of the
package.
- [`CARGO_PKG_LICENSE_FILE`][cargo/8387] The path to the license file.
Compatibility Notes
-------------------
- [The target configuration option `abi_blacklist` has been renamed
to `unsupported_abis`.][74150] The old name will still continue to work.
- [Rustc will now warn if you have a C-like enum that implements `Drop`.][72331]
This was previously accepted but will become a hard error in a future release.
- [Rustc will fail to compile if you have a struct with
`#[repr(i128)]` or `#[repr(u128)]`.][74109] This representation is currently
only allowed on `enum`s.
- [Tokens passed to `macro_rules!` are now always captured.][73293] This helps
ensure that spans have the correct information, and may cause breakage if you
were relying on receiving spans with dummy information.
- [The InnoSetup installer for Windows is no longer available.][72569] This was
a legacy installer that was replaced by a MSI installer a few years ago but
was still being built.
- [`{f32, f64}::asinh` now returns the correct values for negative numbers.]
[72486]
- [Rustc will no longer accept overlapping trait implementations that only
differ in how the lifetime was bound.][72493]
- [Rustc now correctly relates the lifetime of an existential associated
type.][71896] This fixes some edge cases where `rustc` would erroneously
allow you to pass a shorter lifetime than expected.
- [Rustc now dynamically links to `libz` (also called `zlib`) on Linux.][74420]
The library will need to be installed for `rustc` to work, even though we
expect it to be already available on most systems.
- [Tests annotated with `#[should_panic]` are broken on ARMv7 while running
under QEMU.][74820]
- [Pretty printing of some tokens in procedural macros changed.][75453] The
exact output returned by rustc's pretty printing is an unstable
implementation detail: we recommend any macro relying on it to switch to a
more robust parsing system.

Pullup ticket #6329 - requested by gdt lang/rust: NetBSD build fix Revisions pulled up: - lang/rust/Makefile 1.196 --- Module Name: pkgsrc Committed By: gdt Date: Tue Sep 29 16:24:28 UTC 2020 Modified Files: pkgsrc/lang/rust: Makefile Log Message: lang/rust: Adjust openssl bootstrap depends (NetBSD only) On NetBSD, further limit the DEPENDS on openssl to i386. It turns out that the sparc64 and powerpc bootstraps are not linked against openssl as I previously assumed. No change to limiting this DEPENDS to 9+. No change to any other OS. This change is believed to fix rust building on NetBSD 9 sparc64. As discussed on tech-pkg@.
lang/rust: Prune comments about closed PRs
lang/rust: Adjust openssl bootstrap depends (NetBSD only) On NetBSD, further limit the DEPENDS on openssl to i386. It turns out that the sparc64 and powerpc bootstraps are not linked against openssl as I previously assumed. No change to limiting this DEPENDS to 9+. No change to any other OS. This change is believed to fix rust building on NetBSD 9 sparc64. As discussed on tech-pkg@.
lang/rust: Add DEPENDS on openssl for NetBSD >=9 i386 For background, the bootstrap kits need pkgsrc openssl present to run. Then, the built cargo links against libs from pkgsrc openssl. One would expect USE_BUILTIN.openssl=no to cause the later bl3 to depend on pkgsrc openssl, and it does, but then there is a mysterious error about not being able to buildlink heimdal. This commit, relative to how 1.192, modifies comments and adds a straight DEPENDS: DEPENDS+= openssl>=1.1:../../security/openssl only in the case of NetBSD, >=9, i386/sparc64/powerpc. More or less as proposed on tech-pkg, with no responses.
lang/rust: On NetBSD >=9, bl3 on openssl On NetBSD i386 (and sparc64 and powerpc), we have bootstrap kits that are linked against pkgsrc openssl. Previously rust BUILD_DEPENDed on openssl so they could run but this resulted in an installed cargo that linked against that openssl. This changes the depend method to straight bl3, so openssl will be a runtime dependency. This continues to be icky, but after a long period of discussion on the lists, no other this-branch fixes to make NetBSD 9/i386 be able to build rust have been suggested, and further there no objections. It is expected that the bootstrap process will be rototilled after 2020Q3 is cut; this situation is obviously not a good one to continue.
lang/rust: Build-depend on openssl, on NetBSD >8 On NetBSD >8, for several CPU types we depend on compat80, because bootstrap kits are build for NetBSD 8. On those, also add a BUILD_DEPENDS on openssl, because the bootstrap kits need pkgsrc openssl libs. Adjust and reorganize comments (but the only functional change is the NetBSD >8 openssl BUILD_DEPENDS).> Resolves failure to build on NetBSD 9. (The entire "NetBSD>8" section is a hack that can be removed with improved bootstrap generation.)
lang/urst: Depend on compat80 also on NetBSD/sparc64

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]

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

rust: Add support for cross-compiling illumos. It's not really cross-compiled, it's just a different target name, but is treated the same way. Once stabilised and crate support catches up we'll switch over to it by default from x86_64-sun-solaris. Until then I'll build bootstrap kits for both natively. While here fix up a bunch of obvious pkglint warnings.
Upgrade to rust version 1.44.1. Pkgsrc changes: * None. Upstream changes: Version 1.44.1 (2020-06-18) =========================== * [rustfmt accepts rustfmt_skip in cfg_attr again.][73078] * [Don't hash executable filenames on apple platforms, fixing backtraces.] [cargo/8329] * [Fix crashes when finding backtrace on macOS.][71397] * [Clippy applies lint levels into different files.][clippy/5356] [71397]: https://github.com/rust-lang/rust/issues/71397 [73078]: https://github.com/rust-lang/rust/issues/73078 [cargo/8329]: https://github.com/rust-lang/cargo/pull/8329 [clippy/5356]: https://github.com/rust-lang/rust-clippy/issues/5356
Based on suggestion, add the "cross.mk" file which contains settings which may be tweaked to do a cross-build of rust. Include it from the main Makefile.
On second thought, put back the settings for powerpc and earmv7hf, as they are needed when building natively on those platforms.
Remove more of the cross-compile settings now consigned to my own private cross.mk file.
Re-update rust to version 1.44.0.
Pkgsrc changes:
* Remove the clutter caused by the cross-compile setup from Makefile
(Now consigned to my own private cross.mk file.)
* Remove a couple of patches which are now integrated upstream.
* Minor adjustments to a couple of other patches.
* Adjust cargo checksums after upstream upgrades.
* Belatedly bump the curl dependency
* If doing a "dist" build, unset DESTDIR during the build phase,
to work around a mysterious build bug deep in the bowels of llvm,
causing llvm tools to be installed to a directory unexpecetd by
the rest of the rust build, ref.
https://github.com/rust-lang/rust/issues/73132
A "dist" build is not expected to be followed by an "install".
* Bump nearly all bootstraps to 1.43.1; NetBSD earmv7hf bootstrap
bumped to 1.44.0, as that one now finally builds and works.
Upstream changes:
Version 1.44.0 (2020-06-04)
==========================
Language
--------
- [You can now use `async/.await` with `#[no_std]` enabled.][69033]
- [Added the `unused_braces` lint.][70081]
**Syntax-only changes**
- [Expansion-driven outline module parsing][69838]
```rust
#[cfg(FALSE)]
mod foo {
mod bar {
mod baz; // `foo/bar/baz.rs` doesn't exist, but no error!
}
}
```
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
--------
- [Rustc now respects the `-C codegen-units` flag in incremental mode.][70156]
Additionally when in incremental mode rustc defaults to 256 codegen units.
- [Refactored `catch_unwind`, to have zero-cost unless unwinding is enabled and
a panic is thrown.][67502]
- [Added tier 3\* support for the `aarch64-unknown-none` and
`aarch64-unknown-none-softfloat` targets.][68334]
- [Added tier 3 support for `arm64-apple-tvos` and
`x86_64-apple-tvos` targets.][68191]
Libraries
---------
- [Special cased `vec![]` to map directly to `Vec::new()`.][70632] This allows
`vec![]` to be able to be used in `const` contexts.
- [`convert::Infallible` now implements `Hash`.][70281]
- [`OsString` now implements `DerefMut` and `IndexMut` returning
a `&mut OsStr`.][70048]
- [Unicode 13 is now supported.][69929]
- [`String` now implements `From<&mut str>`.][69661]
- [`IoSlice` now implements `Copy`.][69403]
- [`Vec<T>` now implements `From<[T; N]>`.][68692] Where `N` is less than 32.
- [`proc_macro::LexError` now implements `fmt::Display` and `Error`.][68899]
- [`from_le_bytes`, `to_le_bytes`, `from_be_bytes`, `to_be_bytes`,
`from_ne_bytes`, and `to_ne_bytes` methods are now `const` for all
integer types.][69373]

Cargo
-----
- [Added the `cargo tree` command which will print a tree graph of
your dependencies.][cargo/8062] E.g.
```

```
You can also display dependencies on multiple versions of the same crate with
`cargo tree -d` (short for `cargo tree --duplicates`).
Misc
----
- [Rustdoc now allows you to specify `--crate-version` to have rustdoc include
the version in the sidebar.][69494]
Compatibility Notes
-------------------
- [Rustc now correctly generates static libraries on Windows GNU targets with
the `.a` extension, rather than the previous `.lib`.][70937]
- [Removed the `-C no_integrated_as` flag from rustc.][70345]
- [The `file_name` property in JSON output of macro errors now points the actual
source file rather than the previous format of `<NAME macros>`.][70969]
**Note:** this may not point a file that actually exists on the user's system.
- [The minimum required external LLVM version has been bumped to LLVM 8.][71147]
- [`mem::{zeroed, uninitialised}` will now panic when used with types that do
not allow zero initialization such as `NonZeroU8`.][66059] This was
previously a warning.
- [In 1.45.0 (the next release) converting a `f64` to `u32` using the `as`
operator has been defined as a saturating operation.][71269] This was
previously undefined behaviour, you can use the `{f64, f32}::to_int_unchecked`
methods to continue using the current behaviour which may desirable in rare
performance sensitive situations.
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.

rust: uses -std=c++14
Rename rust-bin's PKGNAME to rust-bin. Add rust.mk for rust packages. This allows rust-bin and rust to coexist in bulk builds (for testing, etc), but the packages still may not be installed at the same time. rust.mk as a solution for picking the correct rust variant was suggested by gdt@. It is intended to be included directly by packages that do not use cargo.mk, and indirectly by packages that do use cargo.mk. rust.mk provides one user-settable variable: RUST_TYPE as before, whether to bootstrap rust from source or use official binaries. may be "src" or "bin" And two package-settable variables: RUST_REQ the minimum version of Rust required by the package. defaults to "1.20.0" RUST_RUNTIME whether Rust is a runtime dependency, may be "yes" or "no"
lang/rust: Add comments listing open PRs
lang/rust: fix unsatisfiable condition in cargo.mk
The condition had been the same as in Makefile before 1.174.
Testing for OPSYS was unnecessary since that is included in
MACHINE_PLATFORM as well.
The ${VAR} syntax is easier readable since the number of exclamation
marks matches the number of negations, contrary to !empty, which is
effectively a positive test.
Swapped the order of the conditions since it is easier to read
"generally, but not" than "not this and the general case".
lang/rust: Note pkgbuild 2020Q1 MAK_JOBS mystery On 2020Q1 on pkgbuild (NetBSD 9/amd64), despite MAKE_JOBS_SAFE being set, rust failed to build repeatedly. Note this.
lang/rust: Extend comments about linker fixes Reference the commits that fixed the (a?) problem and the pullup to 9. Note that no pullup to 8 has occured, and add a \todo to explain the plan. Thanks to Martin for pointers and explanation.
lang/rust: Fix MAKE_JOBS_SAFE setting for NetBSD The previous conditional was never true. Assume that it meant to apply to NetBSD <= 9 and not apply to current. Add comments explaining the reason, with \todo for aspects that are unclear, partially rescued from CVS history, and partially from tech-pkg discussion.
rust: Use subst framework instead of manual sed. This was getting unwieldly and didn't support changing multiple checksums in the same file (required for illumos support in 1.44.0). It was also hiding potential bugs, with entries for vendor/rand which do not exist. It's likely this should be in vendor/rand_os as that's what we're actually patching, but perhaps that crate is no longer used as it appears we've never had a checksum fix for it.
Back out the update to version 1.44.0, revert to 1.43.1nb1. This is primarily due to https://github.com/rust-lang/rust/issues/73117 (build failure on NetBSD/i386 8.0) which is reportedly seen also on NetBSD/amd64 9.99.64 and 9.99.65.
Update rust to version 1.44.0.
Pkgsrc changes:
* Remove a couple diffs which are now integrated upstream.
* Adjust cargo checksums after upstream upgrades.
* Belatedly bump the curl dependency
* Unset DESTDIR during the build phase, to work around a mysterious
build bug deep in the bowels of llvm.
* Bump nearly all bootstraps to 1.43.1.

You can also display dependencies on multiple versions of the same crate with
`cargo tree -d` (short for `cargo tree --duplicates`).
Misc
----
- [Rustdoc now allows you to specify `--crate-version` to have rustdoc include
the version in the sidebar.][69494]
Compatibility Notes
-------------------
- [Rustc now correctly generates static libraries on Windows GNU targets with
the `.a` extension, rather than the previous `.lib`.][70937]
- [Removed the `-C no_integrated_as` flag from rustc.][70345]
- [The `file_name` property in JSON output of macro errors now points the actual
source file rather than the previous format of `<NAME macros>`.][70969]
**Note:** this may not point a file that actually exists on the user's system.
- [The minimum required external LLVM version has been bumped to LLVM 8.][71147]
- [`mem::{zeroed, uninitialised}` will now panic when used with types that do
not allow zero initialization such as `NonZeroU8`.][66059] This was
previously a warning.
- [In 1.45.0 (the next release) converting a `f64` to `u32` using the `as`
operator has been defined as a saturating operation.][71269] This was
previously undefined behaviour, you can use the `{f64, f32}::to_int_unchecked`
methods to continue using the current behaviour which may desirable in rare
performance sensitive situations.
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.
- [dep_graph Avoid allocating a set on when the number reads are small.][69778]
- [Replace big JS dict with JSON parsing.][71250]

rust*: Add PKG_SKIP_REASON depending on the value of RUST_TYPE
rust: revert after hasty commit I seen a pkglint error about ggrep and I did not verify if it was a valid tool for USE_TOOLS. Sorry.
rust: fix building on FreeBSD pkgsrc changes: --------------- * fix grep in USE_TOOLS * make parallel building not safe for FreeBSD
revbump after updating security/nettle
Restrict MAKE_JOBS_SAFE=no to older-than-current NetBSD.
rust: Bump libLLVM version for SunOS bootstrap.
Update lang/rust to version 1.43.1. Pkgsrc changes: * None. Upstream changes: Version 1.43.1 (2020-05-07) =========================== * [Updated openssl-src to 1.1.1g for CVE-2020-1967.][71430] * [Fixed the stabilization of AVX-512 features.][71473] * [Fixed `cargo package --list` not working with unpublished dependencies.] [cargo/8151] [71430]: https://github.com/rust-lang/rust/pull/71430 [71473]: https://github.com/rust-lang/rust/issues/71473 [cargo/8151]: https://github.com/rust-lang/cargo/issues/8151
Update lang/rust to version 1.43.0.
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]: https://github.com/rust-lang/rust/pull/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]

lang/rust: remove no-op file from SUBST_FILES
revbump after boost update
rust: netbsd/i386 bootstrap has text relocations, paxctl +m it
As discussed on IRC, use the same environment for build and install. This avoids cargo deciding to rebuild most packages just because it now knows the DESTDIR.
lang/rust: remove trailing slash from dependency path https://mail-index.netbsd.org/pkgsrc-changes/2020/03/26/msg209490.html > This causes problems with bulk builds, at least with limited builds, as > the trailing slash in a package directory name causes pbulk-scan to > fail with "Invalid path from master" and leads to a hung scan phase.
Loosen data/address space limits. Apply it consistently during the build.

revert my change for now Was able to reproduce the hang again. Working on reduced test case.
rust: Update to 1.42.0.
Version 1.42.0 (2020-03-12)
==========================
Language
--------
- [You can now use the slice pattern syntax with subslices.][67712] e.g.
```rust
fn foo(words: &[&str]) {
match words {
["Hello", "World", "!", ..] => println!("Hello World!"),
["Foo", "Bar", ..] => println!("Baz"),
rest => println!("{:?}", rest),
}
}
```
- [You can now use `#[repr(transparent)]` on univariant `enum`s.][68122] Meaning
that you can create an enum that has the exact layout and ABI of the type
it contains.
- [There are some *syntax-only* changes:][67131]
- `default` is syntactically allowed before items in `trait` definitions.
- Items in `impl`s (i.e. `const`s, `type`s, and `fn`s) may syntactically
leave out their bodies in favor of `;`.
- Bounds on associated types in `impl`s are now syntactically allowed
(e.g. `type Foo: Ord;`).
- `...` (the C-variadic type) may occur syntactically directly as the type of
any function parameter.
These are still rejected *semantically*, so you will likely receive an error
but these changes can be seen and parsed by procedural macros and
conditional compilation.
Compiler
--------
- [Added tier 2* support for `armv7a-none-eabi`.][68253]
- [Added tier 2 support for `riscv64gc-unknown-linux-gnu`.][68339]
- [`Option::{expect,unwrap}` and
`Result::{expect, expect_err, unwrap, unwrap_err}` now produce panic messages
pointing to the location where they were called, rather than
`core`'s internals. ][67887]
* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [`iter::Empty<T>` now implements `Send` and `Sync` for any `T`.][68348]
- [`Pin::{map_unchecked, map_unchecked_mut}` no longer require the return type
to implement `Sized`.][67935]
- [`io::Cursor` now derives `PartialEq` and `Eq`.][67233]
- [`Layout::new` is now `const`.][66254]
- [Added Standard Library support for `riscv64gc-unknown-linux-gnu`.][66899]
Stabilized APIs
---------------

- [`CondVar::wait_timeout_while`]
- [`DebugMap::key`]
- [`DebugMap::value`]
- [`ManuallyDrop::take`]
- [`matches!`]

- [`ptr::slice_from_raw_parts`]
Cargo
-----
- [You no longer need to include `extern crate proc_macro;` to be able to
`use proc_macro;` in the `2018` edition.][cargo/7700]
Compatibility Notes
-------------------
- [`Error::description` has been deprecated, and its use will now produce a
warning.][66919] It's recommended to use `Display`/`to_string` instead.
- [`use $crate;` inside macros is now a hard error.][37390] The compiler
emitted forward compatibility warnings since Rust 1.14.0.
- [As previously announced, this release reduces the level of support for
32-bit Apple targets to tier 3.][apple-32bit-drop]. This means that the
source code is still available to build, but the targets are no longer tested
and no release binary is distributed by the Rust project. Please refer to the
linked blog post for more information.

rust: MAKE_JOBS_SAFE=no again, but for non-developers only
rust: set MAKE_JOBS_SAFE=no only if BATCH, i.e. if building inside pbulk It was added so that we have a non-zero change of getting binary packages in the bulk build. I have a sneaking suspicion that most interactive users of pkgsrc comment this line out. Waiting a whole day for rust to build is not acceptable.
rust: add new checksum override

rust: Bump SmartOS bootstrap library requirements.
rust: updated to 1.41.1 What's in 1.41.1 stable Rust 1.41.1 addresses two critical regressions introduced in Rust 1.41.0: a soundness hole related to static lifetimes, and a miscompilation causing segfaults. These regressions do not affect earlier releases of Rust, and we recommend users of Rust 1.41.0 to upgrade as soon as possible. Another issue related to interactions between 'static and Copy implementations, dating back to Rust 1.0, was also addressed by this release.
Update the NetBSD/i686 1.40 bootstrap to fix rpath issue. Bump PKGREVISION.
rust: fix typos in comments.
If we're building for i386 > 8.x or powerpc > 8.x, depend
on the compat80 package.
Also, update the NetBSD/aarch64 bootstrap with a corrected rpath,
so we don't need to tweak LD_LIBRARY_PATH to include ${PREFIX}/lib.
Bump PKGREVISION.
Fix building with external LLVM; allow any Python
rust: src/bootstrap/bin/rustc.rs is not patched, so exclude from SUBST
rust: Update to 1.41.0.
Version 1.41.0 (2020-01-30)
===========================
Language
--------
- [You can now pass type parameters to foreign items when implementing
traits.][65879] E.g. You can now write `impl<T> From<Foo> for Vec<T> {}`.
- [You can now arbitrarily nest receiver types in the `self` position.][64325] E.g. you can
now write `fn foo(self: Box<Box<Self>>) {}`. Previously only `Self`, `&Self`,
`&mut Self`, `Arc<Self>`, `Rc<Self>`, and `Box<Self>` were allowed.
- [You can now use any valid identifier in a `format_args` macro.][66847]
Previously identifiers starting with an underscore were not allowed.
- [Visibility modifiers (e.g. `pub`) are now syntactically allowed on trait items and
enum variants.][66183] These are still rejected semantically, but
can be seen and parsed by procedural macros and conditional compilation.
Compiler
--------
- [Rustc will now warn if you have unused loop `'label`s.][66325]
- [Removed support for the `i686-unknown-dragonfly` target.][67255]
- [Added tier 3 support\* for the `riscv64gc-unknown-linux-gnu` target.][66661]
- [You can now pass an arguments file passing the `@path` syntax
to rustc.][66172] Note that the format differs somewhat from what is
found in other tooling; please see [the documentation][argfile-docs] for
more information.
- [You can now provide `--extern` flag without a path, indicating that it is
available from the search path or specified with an `-L` flag.][64882]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
[argfile-docs]: https://doc.rust-lang.org/nightly/rustc/command-line-arguments.html#path-load-command-line-flags-from-a-path
Libraries
---------
- [The `core::panic` module is now stable.][66771] It was already stable
through `std`.
- [`NonZero*` numerics now implement `From<NonZero*>` if it's a smaller integer
width.][66277] E.g. `NonZeroU16` now implements `From<NonZeroU8>`.
- [`MaybeUninit<T>` now implements `fmt::Debug`.][65013]

- [`std::rc::Weak::weak_count`]
- [`std::rc::Weak::strong_count`]
- [`std::sync::Weak::weak_count`]
- [`std::sync::Weak::strong_count`]
Cargo
-----
- [Cargo will now document all the private items for binary crates
by default.][cargo/7593]
- [`cargo-install` will now reinstall the package if it detects that it is out
of date.][cargo/7560]
- [Cargo.lock now uses a more git friendly format that should help to reduce
merge conflicts.][cargo/7579]
- [You can now override specific dependencies's build settings][cargo/7591] E.g.
`[profile.dev.overrides.image] opt-level = 2` sets the `image` crate's
optimisation level to `2` for debug builds. You can also use
`[profile.<profile>.build_overrides]` to override build scripts and
their dependencies.
Misc
----
- [You can now specify `edition` in documentation code blocks to compile the block
for that edition.][66238] E.g. `edition2018` tells rustdoc that the code sample
should be compiled the 2018 edition of Rust.
- [You can now provide custom themes to rustdoc with `--theme`, and check the
current theme with `--check-theme`.][54733]
- [You can use `#[cfg(doc)]` to compile an item when building documentation.][61351]
Compatibility Notes
-------------------
- [As previously announced 1.41.0 will be the last tier 1 release for 32-bit
Apple targets.][apple-32bit-drop] This means that the source code is still
available to build, but the targets are no longer being tested and release
binaries for those platforms will no longer be distributed by the Rust project.
Please refer to the linked blog post for more information.

rust: fix building on Darwin
rust: Update to 1.40.0.
Version 1.40.0 (2019-12-19)
===========================
Language
--------
- [You can now use tuple `struct`s and tuple `enum` variant's constructors in
`const` contexts.][65188] e.g.
```rust
pub struct Point(i32, i32);
const ORIGIN: Point = {
let constructor = Point;
constructor(0, 0)
};
```
- [You can now mark `struct`s, `enum`s, and `enum` variants with the `#[non_exhaustive]` attribute to
indicate that there may be variants or fields added in the future.][64639]
For example this requires adding a wild-card branch (`_ => {}`) to any match
statements on a non-exhaustive `enum`. [(RFC 2008)]
- [You can now use function-like procedural macros in `extern` blocks and in
type positions.][63931] e.g. `type Generated = macro!();`
- [Function-like and attribute procedural macros can now emit
`macro_rules!` items, so you can now have your macros generate macros.][64035]
- [The `meta` pattern matcher in `macro_rules!` now correctly matches the modern
attribute syntax.][63674] For example `(#[$m:meta])` now matches `#[attr]`,
`#[attr{tokens}]`, `#[attr[tokens]]`, and `#[attr(tokens)]`.
Compiler
--------
- [Added tier 3 support\* for the
`thumbv7neon-unknown-linux-musleabihf` target.][66103]
- [Added tier 3 support for the
`aarch64-unknown-none-softfloat` target.][64589]
- [Added tier 3 support for the `mips64-unknown-linux-muslabi64`, and
`mips64el-unknown-linux-muslabi64` targets.][65843]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.

Cargo
-----
- [Cargo will now always display warnings, rather than only on
fresh builds.][cargo/7450]
- [Feature flags (except `--all-features`) passed to a virtual workspace will
now produce an error.][cargo/7507] Previously these flags were ignored.
- [You can now publish `dev-dependencies` without including
a `version`.][cargo/7333]
Misc
----
- [You can now specify the `#[cfg(doctest)]` attribute to include an item only
when running documentation tests with `rustdoc`.][63803]
Compatibility Notes
-------------------
- [As previously announced, any previous NLL warnings in the 2015 edition are
now hard errors.][64221]
- [The `include!` macro will now warn if it failed to include the
entire file.][64284] The `include!` macro unintentionally only includes the
first _expression_ in a file, and this can be unintuitive. This will become
either a hard error in a future release, or the behavior may be fixed to include all expressions as expected.
- [Using `#[inline]` on function prototypes and consts now emits a warning under
`unused_attribute` lint.][65294] Using `#[inline]` anywhere else inside traits
or `extern` blocks now correctly emits a hard error.

lang/rust: Fix install_name on Darwin
Bump bootstrap requirements to 1.38.0 for Linux-*-i386 Linux-*-x86_64 FreeBSD-*-i386 FreeBSD-*-x86_64 NetBSD-*-powerpc as 1.38 is required to build 1.39.
rust: bump boostrap on Darwin to 1.38.0
rust: Revert back to the 1.38 bootstrap for SunOS.
Regen distinfo and add more patch for RPATH to fix build
rust: Bump SunOS bootstrap to the latest. Rust 1.37 doesn't appear to be new enough to build 1.39, Cargo bails on parsing a lock file, so a number of platforms here will need to be updated.
Undo insertion of tabs in rust source, as this would make the test target fail. Thanks jperkin! Also, bump NetBSD/sparc64 bootstrap to 1.38.
Update rust to version 1.39.0.
Pkgsrc changes:
* Remove patch which no longer applies (but what about RPATH?)
* Adapt a few patches to changed files upstream.
Upstream changes:
Version 1.39.0 (2019-11-07)
===========================
Language
--------
- [You can now create `async` functions and blocks with `async fn`,
`async move {}`, and `async {}` respectively, and you can now call
`.await` on async expressions.][63209]
- [You can now use certain attributes on function, closure, and function
pointer parameters.][64010] These attributes include `cfg`, `cfg_attr`,
`allow`, `warn`, `deny`, `forbid` as well as inert helper attributes used
by procedural macro attributes applied to items. e.g.
```rust
fn len(
#[cfg(windows)] slice: &[u16],
#[cfg(not(windows))] slice: &[u8],
) -> usize {
slice.len()
}
```
- [You can now take shared references to bind-by-move patterns in the
`if` guards of `match` arms.][63118] e.g.
```rust
fn main() {
let array: Box<[u8; 4]> = Box::new([1, 2, 3, 4]);
match array {
nums
// ---- `nums` is bound by move.
if nums.iter().sum::<u8>() == 10
// ^------ `.iter()` implicitly takes a reference to `nums`.
=> {
drop(nums);
// ----------- Legal as `nums` was bound by move and so we have ownership.
}
_ => unreachable!(),
}
}
```
Compiler
--------
- [Added tier 3\* support for the `i686-unknown-uefi` target.][64334]
- [Added tier 3 support for the `sparc64-unknown-openbsd` target.][63595]
- [rustc will now trim code snippets in diagnostics to fit in your terminal.]
[63402] **Note** Cargo currently doesn't use this feature. Refer to
[cargo#7315][cargo/7315] to track this feature's progress.
- [You can now pass `--show-output` argument to test binaries to print the
output of successful tests.][62600]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [`Vec::new` and `String::new` are now `const` functions.][64028]
- [`LinkedList::new` is now a `const` function.][63684]
- [`str::len`, `[T]::len` and `str::as_bytes` are now `const` functions.][63770]
- [The `abs`, `wrapping_abs`, and `overflowing_abs` numeric functions are
now `const`.][63786]
Stabilized APIs
---------------
- [`Pin::into_inner`]
- [`Instant::checked_duration_since`]
- [`Instant::saturating_duration_since`]
Cargo
-----
- [You can now publish git dependencies if supplied with a `version`.]
[cargo/7237]
- [The `--all` flag has been renamed to `--workspace`.][cargo/7241] Using
`--all` is now deprecated.
Misc
----
- [You can now pass `-Clinker` to rustdoc to control the linker used
for compiling doctests.][63834]
Compatibility Notes
-------------------
- [Code that was previously accepted by the old borrow checker, but rejected by
the NLL borrow checker is now a hard error in Rust 2018.][63565] This was
previously a warning, and will also become a hard error in the Rust 2015
edition in the 1.40.0 release.
- [`rustdoc` now requires `rustc` to be installed and in the same directory to
run tests.][63827] This should improve performance when running a large
amount of doctests.
- [The `try!` macro will now issue a deprecation warning.][62672] It is
recommended to use the `?` operator instead.
- [`asinh(-0.0)` now correctly returns `-0.0`.][63698] Previously this
returned `0.0`.

lang: align variable assignments pkglint -Wall -F --only aligned --only indent -r No manual corrections.
Fix CONFIGURE_ARGS for disabling debugging. Build fix so no bump.
rust: Update SmartOS dependencies and tidy.
rust: Fix SunOS builds with newer compilers.
Bump bootstrap version to 1.38.0 for NetBSD/aarch64 (9.0), NetBSD/amd64 (8.0) and NetBSD/i386 (8.0). These bootstraps do not use the pkgsrc llvm, i.e. are built with the rust-llvm option. Disable warnings as fatal errors; 1.38.0 building 1.38.0 produces warnings which would otherwise be fatal, ref. https://github.com/rust-lang/rust/issues/65722 Also, revert back to BUILD_TARGET=build which I mistakenly changed to "dist" previously. Bump PKGVERSION.
rust: Switch to using pkgsrc gzip for extraction on SunOS. Something in the rust-1.38 tarball is tickling a bug in the version of gzip shipped at least on SmartOS.
Update rust to version 1.38.0.
Pkgsrc changes:
* Adapt to the move of the implementation of random numbers.
* Remove patch which is no longer relevant (Signals.inc)
* Cross-build currently fails due to the still unresolved
https://github.com/rust-lang/rust/issues/62558, so bootstrap
kits for 1.38.0 have to be built natively, and will follow shortly.
* Bump bootstrap requirements to 1.37.0 except for armv7-unknown-netbsd-eabihf
which I've neither managed to cross-build nor build natively.
Upstream changes:
Version 1.38.0 (2019-09-26)

Libraries
---------
- [`ascii::EscapeDefault` now implements `Clone` and `Display`.][63421]
- [Derive macros for prelude traits (e.g. `Clone`, `Debug`, `Hash`) are now
available at the same path as the trait.][63056] (e.g. The `Clone` derive
macro is available at `std::clone::Clone`). This also makes all built-in
macros available in `std`/`core` root. e.g. `std::include_bytes!`.
- [`str::Chars` now implements `Debug`.][63000]
- [`slice::{concat, connect, join}` now accepts `&[T]` in addition to
`&T`.][62528]

rust: buildlink with curl; fixes linking on Darwin Rust needs cURL with HTTP2 option enabled; when not found, curl will be built from internal sources.
Bump the version for the following NetBSD bootstraps to 1.37.0: x86_64, i386, powerpc, sparc64, aarch64. The first is built by the rust team, the rest are natively built by yours truly. Cross-builds are currently broken due to https://github.com/rust-lang/rust/issues/62558
rust: on Darwin, use proper shared library name instead of @rpath
Update rust to version 1.37.0
Pkgsrc changes:
* Add a patch to llvm to deal with const dli_saddr.
* Adapt two other patches.
* Cross-build currently fails, so i386, powerpc and sparc64 bootstrap
kits for 1.37.0 are built natively. Missing aarch64 hardware, so that's
not available yet.
* Bump bootstrap requirements to 1.36.0 except for armv7-unknown-netbsd-eabihf
which I've not managed to cross-build.
Upstream changes:
Version 1.37.0 (2019-08-15)
==========================
Language
--------
- `#[must_use]` will now warn if the type is contained in a [tuple][61100],
[`Box`][62228], or an [array][62235] and unused.
- [You can now use the `cfg` and `cfg_attr` attributes on
generic parameters.][61547]
- [You can now use enum variants through type alias.][61682] e.g. You can
write the following:
```rust
type MyOption = Option<u8>;
fn increment_or_zero(x: MyOption) -> u8 {
match x {
MyOption::Some(y) => y + 1,
MyOption::None => 0,
}
}
```
- [You can now use `_` as an identifier for consts.][61347] e.g. You can write
`const _: u32 = 5;`.
- [You can now use `#[repr(align(X)]` on enums.][61229]
- [The `?`/_"Kleene"_ macro operator is now available in the
2015 edition.][60932]
Compiler
--------
- [You can now enable Profile-Guided Optimization with the `-C profile-generate`
and `-C profile-use` flags.][61268] For more information on how to use profile
guided optimization, please refer to the [rustc book][rustc-book-pgo].
- [The `rust-lldb` wrapper script should now work again.][61827]

Compatibility Notes
-------------------
- [Using `...` for inclusive range patterns will now warn by default.][61342]
Please transition your code to using the `..=` syntax for inclusive
ranges instead.

rust: Build against non-internal LLVM by default. This should help with some people's problems with the rust builds being excessively long, and if we ever run into compatibility problems between rust's llvm-current and our shipped version it should be easy to switch on the internal LLVM by default again. I've been using this for some time with Firefox without problems. Bump PKGREVISION.
Bump PKGREVISIONs for perl 5.30.0
Move NetBSD-produced rust bootstrap files to ${MASTER_SITE_LOCAL:=rust/},
i.e. cdn.NetBSD.org (which pulls from ftp.NetBSD.org).
Bump the NetBSD/aarch64 bootstrap to 1.36.0. Please note: this bootstrap is built against 8.99.50, i.e. fairly recent -current. This should make it possible to build rust on this OS version. The previous bootstrap kit was built against 8.99.35, and apparently a C++ update happened since then making the older bootstrap kit unusable on a fresh, new -current.
rust: Make building the internal LLVM optional for everyone (not just Darwin and SunOS). This was posted to tech-pkg@ a while ago with no objections, I've been using it for a while too.
Bump bootstrap version to 1.35.0 for the rest which were not already done, mostly non-NetBSD and non-SunOS.
rust: Switch to the 1.35.0 bootstrap on SunOS.
Update rust to version 1.36.0
Pkgsrc changes:
* NetBSD/sparc64 disabling of "packed" removed ("packed" removed upstream)
* Adapt src_libstd_build.rs patch, update sed'ing of .cargo-checksum.json
Build verified on NetBSD 8.0/amd64.
Upstream changes:
Version 1.36.0 (2019-07-04)
==========================
Language
--------
- [Non-Lexical Lifetimes are now enabled on the 2015 edition.][59114]
- [The order of traits in trait objects no longer affects the semantics of that
object.][59445] e.g. `dyn Send + fmt::Debug` is now equivalent to
`dyn fmt::Debug + Send`, where this was previously not the case.
Libraries
---------
- [`HashMap`'s implementation has been replaced with `hashbrown::HashMap` implem
entation.][58623]
- [`TryFromSliceError` now implements `From<Infallible>`.][60318]
- [`mem::needs_drop` is now available as a const fn.][60364]
- [`alloc::Layout::from_size_align_unchecked` is now available as a const fn.][6
0370]
- [`String` now implements `BorrowMut<str>`.][60404]
- [`io::Cursor` now implements `Default`.][60234]
- [Both `NonNull::{dangling, cast}` are now const fns.][60244]
- [The `alloc` crate is now stable.][59675] `alloc` allows you to use a subset
of `std` (e.g. `Vec`, `Box`, `Arc`) in `#![no_std]` environments if the
environment has access to heap memory allocation.
- [`String` now implements `From<&String>`.][59825]
- [You can now pass multiple arguments to the `dbg!` macro.][59826] `dbg!` will
return a tuple of each argument when there is multiple arguments.
- [`Result::{is_err, is_ok}` are now `#[must_use]` and will produce a warning if
not used.][59648]
Stabilized APIs
---------------
- [`VecDeque::rotate_left`]
- [`VecDeque::rotate_right`]
- [`Iterator::copied`]
- [`io::IoSlice`]

-----
- [Cargo will now produce an error if you attempt to use the name of a required
dependency as a feature.][cargo/6860]
- [You can now pass the `--offline` flag to run cargo without accessing the netw
ork.][cargo/6934]
You can find further change's in [Cargo's 1.36.0 release notes][cargo-1-36-0].
Clippy
------
There have been numerous additions and fixes to clippy, see [Clippy's 1.36.0 rel
ease notes][clippy-1-36-0] for more details.
Misc
----
Compatibility Notes
-------------------
- [`std::arch::x86::_rdtsc` returns `u64` instead of `i64`][stdsimd/559]
- [`std::arch::x86_64::_mm_shuffle_ps` takes an `i32` instead of `u32` for `mask
`][stdsimd/522]
- With the stabilisation of `mem::MaybeUninit`, `mem::uninitialized` use is no
longer recommended, and will be deprecated in 1.38.0.

PKGREVISION bump for anything using python without a PYPKGPREFIX. This is a semi-manual PKGREVISION bump.
Bump the various bootstrap kits for NetBSD to 1.34.0.
Update rust to version 1.34.0.
Pkgsrc changes:
* Bump required rust version to build to 1.33.0.
* Adapt patches to changed file locations.
* (I worry about 32-bit ports, now that Atomic64 apparently is First-Class;
this has been built on NetBSD/amd64 so far)
Upstream changes:
Version 1.34.0 (2019-04-11)
==========================
Language
--------
- [You can now use `#[deprecated = "reason"]`][58166] as a shorthand for
`#[deprecated(note = "reason")]`. This was previously allowed by mistake
but had no effect.
- [You can now accept token streams in `#[attr()]`,`#[attr[]]`, and
`#[attr{}]` procedural macros.][57367]
- [You can now write `extern crate self as foo;`][57407] to import your
crate's root into the extern prelude.
Compiler
--------
- [You can now target `riscv64imac-unknown-none-elf` and
`riscv64gc-unknown-none-elf`.][58406]
- [You can now enable linker plugin LTO optimisations with
`-C linker-plugin-lto`.][58057] This allows rustc to compile your Rust code
into LLVM bitcode allowing LLVM to perform LTO optimisations across C/C++ FFI
boundaries.
- [You can now target `powerpc64-unknown-freebsd`.][57809]

- [The trait bounds have been removed on some of `HashMap<K, V, S>`'s and
`HashSet<T, S>`'s basic methods.][58370] Most notably you no longer require
the `Hash` trait to create an iterator.
- [The `Ord` trait bounds have been removed on some of `BinaryHeap<T>`'s basic
methods.][58421] Most notably you no longer require the `Ord` trait to create
an iterator.
- [The methods `overflowing_neg` and `wrapping_neg` are now `const` functions
for all numeric types.][58044]
- [Indexing a `str` is now generic over all types that
implement `SliceIndex<str>`.][57604]
- [`str::trim`, `str::trim_matches`, `str::trim_{start, end}`, and
`str::trim_{start, end}_matches` are now `#[must_use]`][57106] and will
produce a warning if their returning type is unused.
- [The methods `checked_pow`, `saturating_pow`, `wrapping_pow`, and
`overflowing_pow` are now available for all numeric types.][57873] These are
equivalvent to methods such as `wrapping_add` for the `pow` operation.

lang/rust: Adjust BROKEN pattern per pkglint
Insert a more explicit comment about who prepared the various NetBSD bootstrap kits.
lang/rust: Extend BROKEN to all NetBSD before 8 As discussed on pkgsrc-users, rust does not work on any NetBSD before 8, for any architecture. Omit NetBSD 1 from the broken list, so that this doesn't match NetBSD 10.
lang/rust: Mark BROKEN_ON_PLATFORM for NetBSD-7*-i386 As discussed on pkgsrc-users, mark rust as BROKEN_ON for NetBSD 7 i386. The bootstrap is built for 8, apparently because it doens't build on 7. This is BROKEN_ON not NOT_FOR because it does make sense to want rust on 7 -- it just won't build. (Probably this should be expanded to all arches and all versions < 8.)
rust: Fix another instance of the rand crate for SunOS. While here convert some tabs->spaces that broke the test suite.
Bump bootstrap for armv7/NetBSD to 1.33.0 (still not successfully tested).
Bump bootstrap version for NetBSD/powerpc to 1.33.0.
Bump NetBSD/sparc64 bootstrap kit to (cross-built) 1.33.0.
Bump bootstrap kit for NetBSD/aarch64 to 1.33.0, for NetBSD/aarch64 8.99.34.
Bump NetBSD/i386 bootstrap kit to 1.33.0, natively built on 8.0.
Update rust to version 1.33.0.
Pkgsrc changes:
* Bump required rust version to build to 1.32.0.
* Adapt patches to changed file locations.
* Since we now patch some more vendor/ modules, doctor the corresponding
.cargo-checksum.json files accordingly
Upstream changes:
Version 1.33.0 (2019-02-28)
==========================
Language
--------
- [You can now use the `cfg(target_vendor)` attribute.][57465] E.g.
`#[cfg(target_vendor="apple")] fn main() { println!("Hello Apple!"); }`
- [Integer patterns such as in a match expression can now be exhaustive.][56362]
E.g. You can have match statement on a `u8` that covers `0..=255` and
you would no longer be required to have a `_ => unreachable!()` case.
- [You can now have multiple patterns in `if let` and `while let`
expressions.][57532] You can do this with the same syntax as a `match`
expression. E.g.
```rust
enum Creature {
Crab(String),
Lobster(String),
Person(String),
}
fn main() {
let state = Creature::Crab("Ferris");
if let Creature::Crab(name) | Creature::Person(name) = state {
println!("This creature's name is: {}", name);
}
}
```
- [You can now have irrefutable `if let` and `while let` patterns.][57535]
Using this feature will by default produce a warning as this behaviour
can be unintuitive. E.g. `if let _ = 5 {}`
- [You can now use `let` bindings, assignments, expression statements,
and irrefutable pattern destructuring in const functions.][57175]
- [You can now call unsafe const functions.][57067] E.g.
```rust
const unsafe fn foo() -> i32 { 5 }
const fn bar() -> i32 {
unsafe { foo() }
}
```
- [You can now specify multiple attributes in a `cfg_attr` attribute.][57332]
E.g. `#[cfg_attr(all(), must_use, optimize)]`
- [You can now specify a specific alignment with the `#[repr(packed)]`
attribute.][57049] E.g. `#[repr(packed(2))] struct Foo(i16, i32);` is a
struct with an alignment of 2 bytes and a size of 6 bytes.
- [You can now import an item from a module as an `_`.][56303] This allows you
to import a trait's impls, and not have the name in the namespace. E.g.
```rust
use std::io::Read as _;
// Allowed as there is only one `Read` in the module.
pub trait Read {}
```
- [You may now use `Rc`, `Arc`, and `Pin` as method receivers][56805].
Compiler
--------
- [You can now set a linker flavor for `rustc` with the `-Clinker-flavor`
command line argument.][56351]
- [The mininum required LLVM version has been bumped to 6.0.][56642]
- [Added support for the PowerPC64 architecture on FreeBSD.][57615]
- [The `x86_64-fortanix-unknown-sgx` target support has been upgraded to
tier 2 support.][57130] Visit the [platform support][platform-support]
page for information on Rust's platform support.
- [Added support for the `thumbv7neon-linux-androideabi` and
`thumbv7neon-unknown-linux-gnueabihf` targets.][56947]
- [Added support for the `x86_64-unknown-uefi` target.][56769]
Libraries
---------
- [The methods `overflowing_{add, sub, mul, shl, shr}` are now `const`
functions for all numeric types.][57566]
- [The methods `rotate_left`, `rotate_right`, and `wrapping_{add, sub, mul,
shl, shr}`
are now `const` functions for all numeric types.][57105]
- [The methods `is_positive` and `is_negative` are now `const` functions for
all signed numeric types.][57105]
- [The `get` method for all `NonZero` types is now `const`.][57167]
- [The methods `count_ones`, `count_zeros`, `leading_zeros`, `trailing_zeros`,
`swap_bytes`, `from_be`, `from_le`, `to_be`, `to_le` are now `const` for all
numeric types.][57234]
- [`Ipv4Addr::new` is now a `const` function][57234]

Compatibility Notes
-------------------
- The methods `str::{trim_left, trim_right, trim_left_matches,
trim_right_matches}` are now deprecated in the standard library, and their
usage will now produce a warning. Please use the `str::{trim_start,
trim_end, trim_start_matches, trim_end_matches}` methods instead.
- The `Error::cause` method has been deprecated in favor of `Error::source`
which supports downcasting.

Bump the bootstrap kit for armv7--netbsd-eabihf to 1.32.0. (This has yet to be successfully tested...)
Bump the bootstrap kit for x86_64--netbsd to 1.32.0.
Bump the bootstrap kit for i686--netbsd to 1.32.0, natively built.
Bump sparc64--netbsd bootstrap kit to 1.32.0.
Various updates and additions: * Add commented-out settings for cross-building to aarch64--netbsd * Add clang wrappers (ultimately I could not complete the target build for aarch64/8.0 using clang, due to the build wanting libgcc_s, and its non-presence there, and I could not decipher the build logic) * I built i386--netbsd version 1.31.1, point to my version, since it's not available from ryoon@ and appears to be required to build 1.32.0 * Bump powerpc--netbsd version to 1.32.0 * Add pointer to cross-built aarch64--netbsd version 1.32.0, targeting 8.99.34, using gcc as the target compiler. Untested so far.
delete duplicated LD_LIBRARY_PATH declarations
rust: Put back SunOS fix lost in previous update.
rust: Remove --disable-jemalloc, no longer valid.
Update to 1.32.0
Changelog:
Version 1.32.0 (2019-01-17)
==========================
Language
--------
#### 2018 edition
- [You can now use the `?` operator in macro definitions.][56245] The `?`
operator allows you to specify zero or one repetitions similar to the `*` and
`+` operators.
- [Module paths with no leading keyword like `super`, `self`, or `crate`, will
now always resolve to the item (`enum`, `struct`, etc.) available in the
module if present, before resolving to a external crate or an item the prelude.][56759]
E.g.
```rust
enum Color { Red, Green, Blue }
use Color::*;
```
#### All editions
- [You can now match against `PhantomData<T>` types.][55837]
- [You can now match against literals in macros with the `literal`
specifier.][56072] This will match against a literal of any type.
E.g. `1`, `'A'`, `"Hello World"`
- [Self can now be used as a constructor and pattern for unit and tuple structs.][56365] E.g.
```rust
struct Point(i32, i32);
impl Point {
pub fn new(x: i32, y: i32) -> Self {
Self(x, y)
}
pub fn is_origin(&self) -> bool {
match self {
Self(0, 0) => true,
_ => false,
}
}
}
```
- [Self can also now be used in type definitions.][56366] E.g.
```rust
enum List<T>
where
Self: PartialOrd<Self> // can write `Self` instead of `List<T>`
{
Nil,
Cons(T, Box<Self>) // likewise here
}
```
- [You can now mark traits with `#[must_use]`.][55663] This provides a warning if
a `impl Trait` or `dyn Trait` is returned and unused in the program.
Compiler
--------
- [The default allocator has changed from jemalloc to the default allocator on
your system.][55238] The compiler itself on Linux & macOS will still use
jemalloc, but programs compiled with it will use the system allocator.
- [Added the `aarch64-pc-windows-msvc` target.][55702]
Libraries
---------
- [`PathBuf` now implements `FromStr`.][55148]
- [`Box<[T]>` now implements `FromIterator<T>`.][55843]
- [The `dbg!` macro has been stabilized.][56395] This macro enables you to
easily debug expressions in your rust program. E.g.
```rust
let a = 2;
let b = dbg!(a * 2) + 1;
// ^-- prints: [src/main.rs:4] a * 2 = 4
assert_eq!(b, 5);
```

-------------------
- [The argument types for AVX's
`_mm256_stream_si256`, `_mm256_stream_pd`, `_mm256_stream_ps`][55610] have
been changed from `*const` to `*mut` as the previous implementation
was unsound.

rust: add some kludges to better support NetBSD HEAD-llvm
1) bootstrap rustc adds -lgcc_s when linking
-> Dropped with a BUILDLINK_TRANSFORM
2) bootstrap rustc has shared linkage to libgcc_s.so.1
-> Until upstream changes this to static linkage, we look for
libgcc_s.so.1 in ${FILESDIR} where the user must place it manually.
3) newly built rustc adds -lstdc++ instead of -lc++ when linking llvm
-> fixed with patch-src_librustc__llvm_build.rs
4) newly built rustc adds -lgcc_s when linking
-> fixed with patch-src_libunwind_build.rs
rust: PYTHON_FOR_BUILD_ONLY. Bump.
rust: builds just fine with python-3.7. Remove PYTHON_VERSIONS_ACCEPTED.
Upgrade rust to version 1.31.1. Pkgsrc changes: * Sadly, I had to reinstate the "make tar files" rust code to make it possible to build cross-compiled bootstrap kits. * Add an adjustable "BUILD_TARGET", "dist" for cross-building a bootstrap kit, "build" for a normal native build. * New bootstrap kits built for NetBSD/powerpc, NetBSD/earmv7hf, and NetBSD/sparc64 version 1.31.1. * gcc-wrap script amended to also drop -Wl,--enable-new-dtags (so it could be used outside pkgsrc) * Worked around use of AtomicU64 in release build tool (ugly band-aid patch). Some platforms lack support for that type and associated operations. Upstream changes: - [Fix Rust failing to build on `powerpc-unknown-netbsd`][56562] - [Fix broken go-to-definition in RLS][rls/1171] - [Fix infinite loop on hover in RLS][rls/1170] [56562]: https://github.com/rust-lang/rust/pull/56562 [rls/1171]: https://github.com/rust-lang/rls/issues/1171 [rls/1170]: https://github.com/rust-lang/rls/pull/1170
rust: Restore SunOS support.
Update to 1.31.0
Changelog:
Version 1.31.0 (2018-12-06)
Language
This version marks the release of the 2018 edition of Rust.
New lifetime elision rules now allow for eliding lifetimes in functions and impl headers. E.g. impl<'a> Reader for BufReader<'a> {} can now be impl Reader for BufReader<'_> {}. Lifetimes are still required to be defined in structs.
You can now define and use const functions. These are currently a strict minimal subset of the const fn RFC. Refer to the language reference for what exactly is available.
You can now use tool lints, which allow you to scope lints from external tools using attributes. E.g. #[allow(clippy::filter_map)].
#[no_mangle] and #[export_name] attributes can now be located anywhere in a crate, not just in exported functions.
You can now use parentheses in pattern matches.
Compiler
Updated musl to 1.1.20
Libraries
You can now convert num::NonZero* types to their raw equivalvents using the From trait. E.g. u8 now implements From<NonZeroU8>.
You can now convert a &Option<T> into Option<&T> and &mut Option<T> into Option<&mut T> using the From trait.
You can now multiply (*) a time::Duration by a u32.

Cargo
Cargo will now download crates in parallel using HTTP/2.
You can now rename packages in your Cargo.toml We have a guide on how to use the package key in your dependencies.
rust: Ensure the bundled http-parser is used. Trying to mix and match pkgsrc and bundled dependencies resulted in conflicts between libgit and http-parser, such that cargo was unable to fetch indexes from crates.io with spurious network error regarding Content-Type headers. While here add a note about why these dependencies are currently disabled. Bump PKGREVISION.
rust: speed-up building; clean-ups - use 'build' target for building, not 'dist' - set jobs also for install target - do not generate tarballs; we don't need them, but they take a lot of disk-space - do not install 'src' - do not generate 'install.log' nor 'uninstall.sh' - on Darwin, use headerpad_max_install_names to be able to fix all dylibs - make optimized bootstrap - pkglint fixes - get ready to depend on lang/llvm and devel/jemalloc
Update to 1.30.1
Changelog:
Version 1.30.1 (2018-11-08)
Fixed overflow ICE in rustdoc
Cap Cargo progress bar width at 60 in MSYS terminals
lang/rust: Various fixes. SunOS now needs -D_POSIX_PTHREAD_SEMANTICS and a patch to the rand module to work around getrandom() system call failures. Add -j argument to x.py for the number of make jobs.
Upgrade rust to version 1.30.0.
Upstream changes:
Language
* Procedural macros are now available. These kinds of macros allow
for more powerful code generation. There is a new chapter available
in the Rust Programming Language book that goes further in depth.
* You can now use keywords as identifiers using the raw identifiers
syntax (r#), e.g. let r#for = true;
* Using anonymous parameters in traits is now deprecated with a
warning and will be a hard error in the 2018 edition.
* You can now use crate in paths. This allows you to refer to the
crate root in the path, e.g. use crate::foo; refers to foo in
src/lib.rs.
* Using a external crate no longer requires being prefixed with
::. Previously, using a external crate in a module without a
use statement required let json = ::serde_json::from_str(foo);
but can now be written as let json = serde_json::from_str(foo);.
* You can now apply the #[used] attribute to static items to
prevent the compiler from optimising them away, even if they
appear to be unused, e.g. #[used] static FOO: u32 = 1;
* You can now import and reexport macros from other crates with
the use syntax. Macros exported with #[macro_export] are now
placed into the root module of the crate. If your macro relies
on calling other local macros, it is recommended to export with
the #[macro_export(local_inner_macros)] attribute so users won't
have to import those macros.
* You can now catch visibility keywords (e.g. pub, pub(crate)) in
macros using the vis specifier.
* Non-macro attributes now allow all forms of literals, not just
strings. Previously, you would write #[attr("true")], and you
can now write #[attr(true)].
* You can now specify a function to handle a panic in the Rust
runtime with the #[panic_handler] attribute.
Compiler
* Added the riscv32imc-unknown-none-elf target.
* Added the aarch64-unknown-netbsd target
Libraries
* ManuallyDrop now allows the inner type to be unsized.
Stabilized APIs
* Ipv4Addr::BROADCAST
* Ipv4Addr::LOCALHOST
* Ipv4Addr::UNSPECIFIED
* Ipv6Addr::LOCALHOST
* Ipv6Addr::UNSPECIFIED
* Iterator::find_map
* The following methods are replacement methods for trim_left,
trim_right, trim_left_matches, and trim_right_matches, which
will be deprecated in 1.33.0:
* str::trim_end_matches
* str::trim_end
* str::trim_start_matches
* str::trim_start
Cargo
* cargo run doesn't require specifying a package in workspaces.
* cargo doc now supports --message-format=json. This is equivalent
to calling rustdoc --error-format=json.
* Cargo will now provide a progress bar for builds.
Misc
* rustdoc allows you to specify what edition to treat your code
as with the --edition option.
* rustdoc now has the --color (specify whether to output color)
and --error-format (specify error format, e.g. json) options.
* We now distribute a rust-gdbgui script that invokes gdbgui with
Rust debug symbols.
* Attributes from Rust tools such as rustfmt or clippy are now
available, e.g. #[rustfmt::skip] will skip formatting the next
item.
Pkgsrc changest:
* Explicitly list bootstrap kit version number for each kit we carry,
so that one entry's version doesn't "bleed into" following kits.
* Tweak for handling "earmv7hf" CPU type for NetBSD in the bootstrap.py
script
* Add two patches from Debian for sparc64; rust would generate code
generating unaligned accesses, causing SIGBUS on sparc64
* Update most of the bootstrap kits to version 1.29.2; need minimum
1.29.0 to build 1.30.0.
* Rust regrettably doesn't build for powerpc or earmv7hf in this version,
most probably due to "char" being "unsigned char" on these platforms.
Ref. https://github.com/rust-lang/rust/issues/55465
Upgrade rust to version 1.29.2. Upstream changes: * Workaround for an aliasing-related LLVM bug, which caused miscompilation. * The rls-preview component on the windows-gnu targets has been restored. Pkgsrc changes: * More commented-out settings for cross builds on NetBSD. * Bump bootstrap kit versions to 1.29.2 for powerpc, sparc64 and earm7hf. Anyone up for testing for earm7hf? * Because the built-in versions of libgit2, libssh2 and curl can no longer be built with the pkgsrc-provided headers for those packages (due to version skew; the built-in versions have been updated to un-released newer code), the buildlink3.mk files for those packages have been commented out. * Similarly, to avoid using the native pkgsrc host's headers when cross- building, the gcc-wrap script has been adjusted to also re-point /usr/pkg/include into the destination's root (where those above pacakges are not to be installed). * Also have the gcc-wrap script deal with "-I dir" style directives, and re-point these also into the destination's root. * One patch has been integrated upstream, so removed here.
Make a tentative fix for pkg/53671 by placing the cross compiler
wrapper scripts in ${WRKDIR}/scripts instead of modifying the files/
directory, which conflicts with a read-only pkgsrc.
Fix ${WRKDIR} reference, hint from leot
*: Replace custom tool setup with new ggrep.
Pullup ticket #5841 - requested by ryo lang/rust: build fix Revisions pulled up: - lang/rust/Makefile 1.53 ------------------------------------------------------------------- Module Name: pkgsrc Committed By: ryoon Date: Sun Oct 7 23:12:49 UTC 2018 Modified Files: pkgsrc/lang/rust: Makefile Log Message: Try to fix "warning: duplicate script for target "pre-build" ignored" To generate a diff of this commit: cvs rdiff -u -r1.52 -r1.53 pkgsrc/lang/rust/Makefile
Add pointers to (so far untested) bootstrap kits for sparc64 and earmv7hf. Prepare wrapper script handling for use of clang (not yet fully verified). Adjust the cross-compiler wrapper script to improve the handling when used as the linker: * Insert "linker tweaks" before first -L or -l * Handle "-L arg" style as well as "-Larg" * Add "-Wl,-rpath-link" to the linker tweaks just to be sure... Bump PKGREVISION.
Hm, we need to ensure the gcc-wrap script is executable.
Typo fix, CROSS_TARGET -> GNU_CROSS_TARGET.
Add the bits required to build rust on NetBSD/powerpc ports, and point to the bootstrap kit for NetBSD/powerpc I'm hosting at the moment. Also add the bits I used when cross-building the NetBSD/powerpc rust on amd64, commented out, as well as the gcc / c++ wrapper script I used in the process. The changes affecting other ports are: * We now add LD_LIBRARY_PATH in the make environment, so that if the bootstrap kit binaries and shared libraries don't have the $ORIGIN-style RPATH entries, it will still work * The bootstrap.py script has been changed to turn off the generation of debuginfo in "RUSTFLAGS"; for some so far unknown reason, the NetBSD/powerpc rust will not build if you ask for debug info. This could perhaps have been made OS-variant dependent, but isn't at the moment. So .. bump PKGREVISION.
My website URI for bootsrap kit has changed. The older website will provide older taballs, however new tarballs will be provided at the newer website only.

Restore maybe accidental comment-out in NetBSD/i386 conditional. And do not use 1.28.0 bootstrap for FreeBSD. This will fix the problem from gdt@.
Recursive bump for perl5-5.28.0
revbump after boost-libs update
rust: Switch to the 1.28.0 bootstrap for SunOS too. It looks like I accidentally built the 1.27.2 bootstrap without the stack clash fix required for newer illumos platforms, so just use 1.28.0 which was built correctly for now.
Enable NetBSD/i386 support and fix NetBSD build * 1.27.2 bootstrap kit has a serious bug and does not work under NetBSD. So use 1.28.0 instead.
rust: Update to version 1.28.0.
NetBSD/i386 is temporarily disabled due to missing binary bootstraps.
Version 1.28.0 (2018-08-02)
===========================
Language
--------
- [The `#[repr(transparent)]` attribute is now stable.][51562] This attribute
allows a Rust newtype wrapper (`struct NewType<T>(T);`) to be represented as
the inner type across Foreign Function Interface (FFI) boundaries.
- [The keywords `pure`, `sizeof`, `alignof`, and `offsetof` have been unreserved
and can now be used as identifiers.][51196]
- [The `GlobalAlloc` trait and `#[global_allocator]` attribute are now
stable.][51241] This will allow users to specify a global allocator for
their program.
- [Unit test functions marked with the `#[test]` attribute can now return
`Result<(), E: Debug>` in addition to `()`.][51298]
- [The `lifetime` specifier for `macro_rules!` is now stable.][50385] This
allows macros to easily target lifetimes.
Compiler
--------
- [The `s` and `z` optimisation levels are now stable.][50265] These optimisations
prioritise making smaller binary sizes. `z` is the same as `s` with the
exception that it does not vectorise loops, which typically results in an even
smaller binary.
- [The short error format is now stable.][49546] Specified with
`--error-format=short` this option will provide a more compressed output of
rust error messages.
- [Added a lint warning when you have duplicated `macro_export`s.][50143]
- [Reduced the number of allocations in the macro parser.][50855] This can
improve compile times of macro heavy crates on average by 5%.
Libraries
---------
- [Implemented `Default` for `&mut str`.][51306]
- [Implemented `From<bool>` for all integer and unsigned number types.][50554]
- [Implemented `Extend` for `()`.][50234]
- [The `Debug` implementation of `time::Duration` should now be more easily
human readable.][50364] Previously a `Duration` of one second would printed as
`Duration { secs: 1, nanos: 0 }` and will now be printed as `1s`.
- [Implemented `From<&String>` for `Cow<str>`, `From<&Vec<T>>` for `Cow<[T]>`,
`From<Cow<CStr>>` for `CString`, `From<CString>, From<CStr>, From<&CString>`
for `Cow<CStr>`, `From<OsString>, From<OsStr>, From<&OsString>` for
`Cow<OsStr>`, `From<&PathBuf>` for `Cow<Path>`, and `From<Cow<Path>>`
for `PathBuf`.][50170]
- [Implemented `Shl` and `Shr` for `Wrapping<u128>`
and `Wrapping<i128>`.][50465]
- [`DirEntry::metadata` now uses `fstatat` instead of `lstat` when
possible.][51050] This can provide up to a 40% speed increase.
- [Improved error messages when using `format!`.][50610]

Cargo
-----
- [Cargo will now no longer allow you to publish crates with build scripts that
modify the `src` directory.][cargo/5584] The `src` directory in a crate should be
considered to be immutable.
Misc
----
- [The `suggestion_applicability` field in `rustc`'s json output is now
stable.][50486] This will allow dev tools to check whether a code suggestion
would apply to them.
Compatibility Notes
-------------------
- [Rust will no longer consider trait objects with duplicated constraints to
have implementations.][51276] For example the below code will now fail
to compile.
```rust
trait Trait {}
impl Trait + Send {
fn test(&self) { println!("one"); } //~ ERROR duplicate definitions with name `test`
}
impl Trait + Send + Send {
fn test(&self) { println!("two"); }
}

rustdoc would execute plugins in the /tmp/rustdoc/plugins directory when running, which enabled executing code as some other user on a given machine. This release fixes that vulnerability; you can read more about this on the blog.
Thank you to Red Hat for responsibily disclosing this vulnerability to us.
Compatibility Notes
The borrow checker was fixed to avoid an additional potential unsoundness when using match ergonomics: #51415, #49534
rust: Set CARGO_BUILD_JOBS to MAKE_JOBS. cargo defaults to using the number of CPUs detected on the host machine, which is a terrible heuristic and can easily lead to DRAM exhaustion, especially in a zones environment where you have access to the full number of CPUs but will be limited to a portion of available DRAM. Tidy up a SunOS section while here.
*: Move SUBST_STAGE from post-patch to pre-configure Performing substitutions during post-patch breaks tools such as mkpatches, making it very difficult to regenerate correct patches after making changes, and often leading to substituted string replacements being committed.
Update to 1.27.0
* SunOS parts are from jperkin@.
Changelog:
Version 1.27.0 (2018-06-21)
Language
Removed 'proc' from the reserved keywords list. This allows proc to be used as an identifer.
The dyn syntax is now available. This syntax is equivalent to the bare Trait syntax, and should make it clearer when being used in tandem with impl Trait. Since it is equivalent to the following syntax: &Trait == &dyn Trait, &mut Trait == &mut dyn Trait, and Box<Trait> == Box<dyn Trait>.
Attributes on generic parameters such as types and lifetimes are now stable. e.g. fn foo<#[lifetime_attr] 'a, #[type_attr] T: 'a>() {}
The #[must_use] attribute can now also be used on functions as well as types. It provides a lint that by default warns users when the value returned by a function has not been used.
Compiler
Added the armv5te-unknown-linux-musl target.
Libraries
SIMD (Single Instruction Multiple Data) on x86/x86_64 is now stable. This includes arch::x86 & arch::x86_64 modules which contain SIMD intrinsics, a new macro called is_x86_feature_detected!, the #[target_feature(enable="")] attribute, and adding target_feature = "" to the cfg attribute.
A lot of methods for [u8], f32, and f64 previously only available in std are now available in core.
The generic Rhs type parameter on ops::{Shl, ShlAssign, Shr} now defaults to Self.
std::str::replace now has the #[must_use] attribute to clarify that the operation isn't done in place.
Clone::clone, Iterator::collect, and ToOwned::to_owned now have the #[must_use] attribute to warn about unused potentially expensive allocations.

Cargo
cargo-metadata now includes authors, categories, keywords, readme, and repository fields.
Added the --target-dir optional argument. This allows you to specify a different directory than target for placing compilation artifacts.
Cargo will be adding automatic target inference for binaries, benchmarks, examples, and tests in the Rust 2018 edition. If your project specifies specific targets e.g. using [[bin]] and have other binaries in locations where cargo would infer a binary, Cargo will produce a warning. You can disable this feature ahead of time by setting any of the following autobins, autobenches, autoexamples, autotests to false.
Cargo will now cache compiler information. This can be disabled by setting CARGO_CACHE_RUSTC_INFO=0 in your environment.
Misc
Added "The Rustc book" into the official documentation. "The Rustc book" documents and teaches how to use the rustc compiler.
All books available on doc.rust-lang.org are now searchable.
Compatibility Notes
Calling a CharExt or StrExt method directly on core will no longer work. e.g. ::core::prelude::v1::StrExt::is_empty("") will not compile, "".is_empty() will still compile.
Debug output on atomic::{AtomicBool, AtomicIsize, AtomicPtr, AtomicUsize} will only print the inner type. e.g. print!("{:?}", AtomicBool::new(true)) will print true not AtomicBool(true).
The maximum number for repr(align(N)) is now 2^29. Previously you could enter higher numbers but they were not supported by LLVM. Up to 512MB alignment should cover all use cases.
rust: Restore SunOS support.

Language
Closures now implement Copy and/or Clone if all captured variables implement either or both traits.
The inclusive range syntax e.g. for x in 0..=10 is now stable.
Stablise '_. The underscore lifetime can be used anywhere where a lifetime can be elided.
impl Trait is now stable allowing you to have abstract types in returns or in function parameters. e.g. fn foo() -> impl Iterator<Item=u8> or fn open(path: impl AsRef<Path>).
Pattern matching will now automatically apply dereferences.
128-bit integers in the form of u128 and i128 are now stable.
main can now return Result<(), E: Debug> in addition to ().
A lot of operations are now available in a const context. E.g. You can now index into constant arrays, reference and dereference into constants, and use Tuple struct constructors.
Fixed entry slice patterns are now stable. e.g.
let points = [1, 2, 3, 4];
match points {
[1, 2, 3, 4] => println!("All points were sequential."),
_ => println!("Not all points were sequential."),
}
Compiler
LLD is now used as the default linker for wasm32-unknown-unknown.
Fixed exponential projection complexity on nested types. This can provide up to a ~12% reduction in compile times for certain crates.
Added the --remap-path-prefix option to rustc. Allowing you to remap path prefixes outputted by the compiler.
Added powerpc-unknown-netbsd target.
Libraries
Implemented From<u16> for usize & From<{u8, i16}> for isize.
Added hexadecimal formatting for integers with fmt::Debug e.g. assert!(format!("{:02x?}", b"Foo\0") == "[46, 6f, 6f, 00]")
Implemented Default, Hash for cmp::Reverse.
Optimized str::repeat being 8x faster in large cases.
ascii::escape_default is now available in libcore.

Misc
Rust by example is now shipped with new releases
Compatibility Notes
Deprecated net::lookup_host.
rustdoc has switched to pulldown as the default markdown renderer.

# What's in 1.23.0 stable
New year, new Rust! For our first improvement today, we now avoid
some unnecessary copies in certain situations. We've seen memory
usage of using rustc to drop 5-10% with this change; it may be
different with your programs.
The documentation team has been on a long journey to move rustdoc
to use CommonMark. Previously, rustdoc never guaranteed which
markdown rendering engine it used, but we're finally committing to
CommonMark. As part of this release, we render the documentation
with our previous renderer, Hoedown, but also render it with a
CommonMark compliant renderer, and warn if there are any differences.
There should be a way for you to modify the syntax you use to render
correctly under both; we're not aware of any situations where this
is impossible. Docs team member Guillaume Gomez has written a blog
post showing some common differences and how to solve them. In a
future release, we will switch to using the CommonMark renderer by
default. This warning landed in nightly in May of last year, and
has been on by default since October of last year, so many crates
have already fixed any issues that they've found.
In other documentation news, historically, Cargo's docs have been
a bit strange. Rather than being on doc.rust-lang.org, they've been
at doc.crates.io. With this release, that's changing. You can now
find Cargo's docs at doc.rust-lang.org/cargo. Additionally, they've
been converted to the same format as our other long-form documentation.
We'll be adding a redirect from doc.crates.io to this page, and
you can expect to see more improvements and updates to Cargo's docs
throughout the year.
See the detailed release notes for more.
## Library stabilizations
As of Rust 1.0, a trait named AsciiExt existed to provide ASCII
related functionality on u8, char, [u8], and str. To use it, you'd
write code like this:
use std::ascii::AsciiExt;
let ascii = 'a';
let non_ascii = '❤';
let int_ascii = 97;
assert!(ascii.is_ascii());
assert!(!non_ascii.is_ascii());
assert!(int_ascii.is_ascii());
In Rust 1.23, these methods are now defined directly on those types,
and so you no longer need to import the trait. Thanks to our
stability guarantees, this trait still exists, so if you'd like to
still support Rust versions before Rust 1.23, you can do this:
#[allow(unused_imports)]
use std::ascii::AsciiExt;
...to suppress the related warning. Once you drop support for older
Rusts, you can remove both lines, and everything will continue to
work.
Additionally, a few new APIs were stabilized this release:
The various std::sync::atomic types now implement From their
non-atomic types. For example, let x = AtomicBool::from(true);.
() now implements FromIterator<()>; check the PR for a neat
use-case. RwLock<T> has had its Send restriction lifted
See the detailed release notes for more.
## Cargo features
cargo check can now check your unit tests.
cargo uninstall can now uninstall more than one package in one
command.

use std::ascii::AsciiExt;
let ascii = 'a';
let non_ascii = '❤';
let int_ascii = 97;
assert!(ascii.is_ascii());
assert!(!non_ascii.is_ascii());
assert!(int_ascii.is_ascii());
In Rust 1.23, these methods are now defined directly on those types,
and so you no longer need to import the trait. Thanks to our
stability guarantees, this trait still exists, so if you'd like to
still support Rust versions before Rust 1.23, you can do this:
#[allow(unused_imports)]
use std::ascii::AsciiExt;
...to suppress the related warning. Once you drop support for older
Rusts, you can remove both lines, and everything will continue to
work.
Additionally, a few new APIs were stabilized this release:
The various std::sync::atomic types now implement From their
non-atomic types. For example, let x = AtomicBool::from(true);.
() now implements FromIterator<()>; check the PR for a neat
use-case. RwLock<T> has had its Send restriction lifted
See the detailed release notes for more.
## Cargo features
cargo check can now check your unit tests.
cargo uninstall can now uninstall more than one package in one
command.
rust: Restore SunOS support.
Revbump after boost update
Fix NetBSD/i386 8 build. Fix PR pkg/52809
Bump PKGREVISION after binary change
Use internal llvm to fix build after llvm 5 update and bump PKGREVISION
rust: remove lib/rustlib/uninstall.sh It is not used in pkgsrc and contains a hardcoded reference to /bin/bash.
Update to 1.22.1
* Disable SunOS support for a while
Changelog:
Version 1.22.1 (2017-11-22)
Update Cargo to fix an issue with macOS 10.13 "High Sierra"
Version 1.22.0 (2017-11-22)
Language
non_snake_case lint now allows extern no-mangle functions
Now accepts underscores in unicode escapes
T op= &T now works for numeric types. eg. let mut x = 2; x += &8;
types that impl Drop are now allowed in const and static types
Compiler
rustc now defaults to having 16 codegen units at debug on supported
platforms.
rustc will no longer inline in codegen units when compiling for debug
This should decrease compile times for debug builds.
strict memory alignment now enabled on ARMv6
Remove support for the PNaCl target le32-unknown-nacl
Libraries
Allow atomic operations up to 32 bits on armv5te_unknown_linux_gnueabi
Box<Error> now impls From<Cow<str>>

fs::copy now returns the length of the main stream on NTFS.
Properly detect overflow in Instant += Duration.
impl Hasher for {&mut Hasher, Box<Hasher>}
impl fmt::Debug for SplitWhitespace.
Option<T> now impls Try This allows for using ? with Option types.
Stabilized APIs
Cargo
Cargo will now build multi file examples in subdirectories of the
examples folder that have a main.rs file.
Changed [root] to [package] in Cargo.lock Packages with the old
format will continue to work and can be updated with cargo update.
Now supports vendoring git repositories
Misc
libbacktrace is now available on Apple platforms.
Stabilised the compile_fail attribute for code fences in doc-comments.
This now lets you specify that a given code example will fail to compile.
Compatibility Notes
The minimum Android version that rustc can build for has been
bumped to 4.0 from 2.3
Allowing T op= &T for numeric types has broken some type inference cases
Fails with Python > 2.7 - add PYTHON_VERSIONS_ACCEPTED=27
rust: Restore SunOS support. Switch back to configure script. No changes intended on other platforms, the configure script arguments should be identical to those previously found in config.toml. Doing it this way makes it a lot easier to have per-OS configuration.
rust: reorganize bootstrap toolchain extraction a bit - run install.sh instead of manually moving around directories - allow user to set RUST_BOOTSTRAP_PATH (and RUST_ARCH if needed) in mk.conf to use a locally installed bootstrap toolchain.
Update to 1.21.0

Cargo
Cargo API token location moved from ~/.cargo/config to ~/.cargo/credentials.
Cargo will now build main.rs binaries that are in sub-directories of src/bin. ie. Having src/bin/server/main.rs and src/bin/client/main.rs generates target/debug/server and target/debug/client
You can now specify version of a binary when installed through cargo install using --vers.
Added --no-fail-fast flag to cargo to run all benchmarks regardless of failure.
Changed the convention around which file is the crate root.

The reimplementation of {f32, f64}::is_sign_{negative, positive} now takes the sign of NaN into account where previously didn't.
Version 1.19.0 (2017-07-20)
Language
Numeric fields can now be used for creating tuple structs. RFC 1506 For example struct Point(u32, u32); let x = Point { 0: 7, 1: 0 };.
Macro recursion limit increased to 1024 from 64.
Added lint for detecting unused macros.
loop can now return a value with break. RFC 1624 For example: let x = loop { break 7; };
C compatible unions are now available. RFC 1444 They can only contain Copy types and cannot have a Drop implementation. Example: union Foo { bar: u8, baz: usize }
Non capturing closures can now be coerced into fns, RFC 1558 Example: let foo: fn(u8) -> u8 = |v: u8| { v };
Compiler
Add support for bootstrapping the Rust compiler toolchain on Android.
Change arm-linux-androideabi to correspond to the armeabi official ABI. If you wish to continue targeting the armeabi-v7a ABI you should use --target armv7-linux-androideabi.
Fixed ICE when removing a source file between compilation sessions.
Minor optimisation of string operations.
Compiler error message is now aborting due to previous error(s) instead of aborting due to N previous errors This was previously inaccurate and would only count certain kinds of errors.
The compiler now supports Visual Studio 2017
The compiler is now built against LLVM 4.0.1 by default
Added a lot of new error codes
Added target-feature=+crt-static option RFC 1721 Which allows libraries with C Run-time Libraries(CRT) to be statically linked.
Fixed various ARM codegen bugs
Libraries
String now implements FromIterator<Cow<'a, str>> and Extend<Cow<'a, str>>
Vec now implements From<&mut [T]>
Box<[u8]> now implements From<Box<str>>
SplitWhitespace now implements Clone
[u8]::reverse is now 5x faster and [u16]::reverse is now 1.5x faster

Cargo
Build scripts can now add environment variables to the environment the crate is being compiled in. Example: println!("cargo:rustc-env=FOO=bar");
Subcommands now replace the current process rather than spawning a new child process
Workspace members can now accept glob file patterns
Added --all flag to the cargo bench subcommand to run benchmarks of all the members in a given workspace.
Updated libssh2-sys to 0.2.6
Target directory path is now in the cargmetadata
Cargo no longer checks out a local working directory for the crates.io index This should provide smaller file size for the registry, and improve cloning times, especially on Windows machines.
Added an --exclude option for excluding certai using the --all option
Cargo will now automatically retry when receiving a 5xx error from crates.io
The --features option now accepts multiple comma or space delimited values.
Added support for custom target specific runners
Misc
Added ow prefer to download rust packages with XZ compression over GZip packages.
Added the ability to escape # in rust documentation By adding additional #'s ie. ## is now #
Compatibility Notes
MutexGuard<T> may only be Sync if T is Sync.
-Z flagning for a year previous to this.
As a result of the -Z flag change, the cargo-check plugin no longer works. Users should migrate to the built-in check command, which has been available since 1.16.
Ending a float literal with ._ is now a hard erro use ::self::foo; is now a hard error. self paths are always relative while the :: prefix makes a path absolute, but was ignored and the path was relative regardless.
Floating point constants in match patterns is now a hard error This was previously ts that don't derive PartialEq & Eq used match patterns is now a hard error This was previously a warning.
Lifetimes named '_ are no longer allowed. This was previously a warning.
From the pound escape, lines consisting of multiple #s are now visible
It is an error to reexport private enum variants. This is known to break a number of crates that depend on an older version of mustache.
On Windows, if VCINSTALLDIR is set incorrectly, rustc will try to use it to find the linker, and the build will fail where it did not previously
Version 1.18.0 (2017-06-08)
Language
Stabilize pub(restricted) pub can now accept a module path to make the item visible to just that module tree. Also accepts the keyword crate to make something public to the whole crate but not users of the library. Example: pub(crate) mod utils;. RFC 1422.
Stabilize #![windows_subsystem] attribute conservative exposure of the /SUBSYSTEM linker flag on Windows platforms. RFC 1665.
Refactor of trait object type parsing Now ty in macros can accept types like Write + Send, trailing + are now supported in trait objects, and better error reporting for trait objects starting with ?Sized.
0e+10 is now a valid floating point literal
Now warns if you bind a lifetime parameter to 'static
Tuples, Enum variant fields, and structs with no repr attribute or with #[repr(Rust)] are reordered to minimize padding and produce a smaller representation in some cases.
Compiler
rustc can now emit mir with --emit mir
Improved LLVM IR for trivial functions
Added explanation for E0090(Wrong number of lifetimes are supplied)
rustc compilation is now 15%-20% faster Thanks to optimisation opportunities found through profiling
Improved backtrace formatting when panicking
Libraries
Specialized Vec::from_iter being passed vec::IntoIter if the iterator hasn't been advanced the original Vec is reassembled with no actual iteration or reallocation.
Simplified HashMap Bucket interface provides performance improvements for iterating and cloning.
Specialize Vec::from_elem to use calloc
Fixed Race condition in fs::create_dir_all
No longer caching stdio on Windows

Added partial Pijul support Pijul is a version control system in Rust. You can now create new cargo projects with Pijul using cargo new --vcs pijul
Now always emits build script warnings for crates that fail to build
Added Android build support
Added --bins and --tests flags now you can build all programs of a certain type, for example cargo build --bins will build all binaries.
Added support for haiku
Misc
rustdoc can now use pulldown-cmark with the --enable-commonmark flag
Added rust-winbg script for better debugging on Windows
Rust now uses the official cross compiler for NetBSD
rustdoc now accepts # at the start of files
Fixed jemalloc support for musl
Compatibility Notes
Changes to how the 0 flag works in format! Padding zeroes are now always placed after the sign if it exists and before the digits. With the # flag the zeroes are placed after the prefix and before the digits.
Due to the struct field optimisation, using transmute on structs that have no repr attribute or #[repr(Rust)] will no longer work. This has always been undefined behavior, but is now more likely to break in practice.
The refactor of trait object type parsing fixed a bug where + was receiving the wrong priority parsing things like &for<'a> Tr<'a> + Send as &(for<'a> Tr<'a> + Send) instead of (&for<'a> Tr<'a>) + Send
Overlapping inherent impls are now a hard error
PartialOrd and Ord must agree on the ordering.
rustc main.rs -o out --emit=asm,llvm-ir Now will output out.asm and out.ll instead of only one of the filetypes.
calling a function that returns Self will no longer work when the size of Self cannot be statically determined.
rustc now builds with a "pthreads" flavour of MinGW for Windows GNU this has caused a few regressions namely:
Changed the link order of local static/dynamic libraries (respecting the order on given rather than having the compiler reorder).
Changed how MinGW is linked, native code linked to dynamic libraries may require manually linking to the gcc support library (for the native code itself)
Version 1.17.0 (2017-04-27)
Language
The lifetime of statics and consts defaults to 'static. RFC 1623
Fields of structs may be initialized without duplicating the field/variable names. RFC 1682
Self may be included in the where clause of impls. RFC 1647
When coercing to an unsized type lifetimes must be equal. That is, there is no subtyping between T and U when T: Unsize<U>. For example, coercing &mut [&'a X; N] to &mut [&'b X] requires 'a be equal to 'b. Soundness fix.
Values passed to the indexing operator, [], automatically coerce
Static variables may contain references to other statics
Compiler
Exit quickly on only --emit dep-info
Make -C relocation-model more correctly determine whether the linker creates a position-independent executable
Add -C overflow-checks to directly control whether integer overflow panics
The rustc type checker now checks items on demand instead of in a single in-order pass. This is mostly an internal refactoring in support of future work, including incremental type checking, but also resolves RFC 1647, allowing Self to appear in impl where clauses.

rustdoc --test includes file names in test names
This release includes builds of std for sparc64-unknown-linux-gnu, aarch64-unknown-linux-fuchsia, and x86_64-unknown-linux-fuchsia.
Initial support for aarch64-unknown-freebsd
Initial support for i686-unknown-netbsd
This release no longer includes the old makefile build system. Rust is built with a custom build system, written in Rust, and with Cargo.
Add Debug implementations for libcollection structs
TypeId implements PartialOrd and Ord
--test-threads=0 produces an error
rustup installs documentation by default
The Rust source includes NatVis visualizations. These can be used by WinDbg and Visual Studio to improve the debugging experience.
Compatibility Notes
Rust 1.17 does not correctly detect the MSVC 2017 linker. As a workaround, either use MSVC 2015 or run vcvars.bat.
When coercing to an unsized type lifetimes must be equal. That is, disallow subtyping between T and U when T: Unsize<U>, e.g. coercing &mut [&'a X; N] to &mut [&'b X] requires 'a be equal to 'b. Soundness fix.
format! and Display::to_string panic if an underlying formatting implementation returns an error. Previously the error was silently ignored. It is incorrect for write_fmt to return an error when writing to a string.
In-tree crates are verified to be unstable. Previously, some minor crates were marked stable and could be accessed from the stable toolchain.
Rust git source no longer includes vendored crates. Those that need to build with vendored crates should build from release tarballs.
Fix inert attributes from proc_macro_derives
During crate resolution, rustc prefers a crate in the sysroot if two crates are otherwise identical. Unlikely to be encountered outside the Rust build system.
Fixed bugs around how type inference interacts with dead-code. The existing code generally ignores the type of dead-code unless a type-hint is provided; this can cause surprising inference interactions particularly around defaulting. The new code uniformly ignores the result type of dead-code.
Tuple-struct constructors with private fields are no longer visible
Lifetime parameters that do not appear in the arguments are now considered early-bound, resolving a soundness bug (#32330). The hr_lifetime_in_assoc_type future-compatibility lint has been in effect since April of 2016.
rustdoc: fix doctests with non-feature crate attributes

Update lang/rust to 1.16.0. Changes since 1.15.1: Version 1.16.0 (2017-03-16) =========================== Language -------- * Lifetimes in statics and consts default to `'static`. [RFC 1623] * [The compiler's `dead_code` lint now accounts for type aliases][38051]. * [Uninhabitable enums (those without any variants) no longer permit wildcard match patterns][38069] * [Clean up semantics of `self` in an import list][38313] * [`Self` may appear in `impl` headers][38920] * [`Self` may appear in struct expressions][39282] Compiler -------- * [`rustc` now supports `--emit=metadata`, which causes rustc to emit a `.rmeta` file containing only crate metadata][38571]. This can be used by tools like the Rust Language Service to perform metadata-only builds. * [Levenshtein based typo suggestions now work in most places, while previously they worked only for fields and sometimes for local variables][38927].

Update lang/rust to 1.15.1. Changes since 1.11.0 are too numerous to list, but can be found here: https://github.com/rust-lang/rust/blob/master/RELEASES.md Add a stage0-bootstrap target to simplify generation of bootstrap kits for platforms which are not supported upstream (primarily SmartOS).
Recursive revbump from llvm 3.9.0
Restore accidentally deleted comment and use .NetBSD suffix Thank you, jperkin@.
Add NetBSD/amd64 support This package must be built with pkgtools/cwrappers with USE_CWRAPPERS=yes.
Only try to fetch stage2 if it's available for the target.
Import rust 1.11.0 as lang/rust into pkgsrc.
pkgsrc notes:
* The build requires binary bootstraps built by the Rust team. Due
to the requirement that only the previous version is supported as
a bootstrap compiler, and new versions of Rust are released every
6 weeks, it is unlikely to be practical to build TNF bootstraps.
Users should evaluate whether they trust binaries from upstream.
* There is currently no SunOS bootstrap provided by the Rust team,
so for now a version built by myself is provided by Joyent.
* Only Darwin/Linux/SunOS are currently supported. The Rust team do
provide NetBSD bootstraps so support should be easy enough to add.
Information about Rust from the DESCR:
Rust is a systems programming language focused on three goals: safety,
speed, and concurrency. It maintains these goals without having a
garbage collector, making it a useful language for a number of use cases
other languages aren't good at: embedding in other languages, programs
with specific space and time requirements, and writing low-level code,
like device drivers and operating systems.
It improves on current languages targeting this space by having a number
of compile-time safety checks that produce no runtime overhead, while
eliminating all data races. Rust also aims to achieve "zero-cost
abstractions" even though some of these abstractions feel like those of
a high-level language. Even then, Rust still allows precise control
like a low-level language would.
