17c7e17fbc Accepting request 862664 from home:manfred-h:devel:languages:rust:rust-1.49
FWIW, I've now used rust-1.49.0 successfully to build both MozillaFirefox-84.0.2 and firefox-esr-78.6.1!
FWIW2, I raised the memory constraints for x86_64 from 8 to 11G, because otherwise a build got killed due to OOM too often.

This SR contains everything which got accepted for 1.48 just recently.

- Update to version 1.49.0
  + Language
  - Unions can now implement Drop, and you can now have a field in
    a union with ManuallyDrop<T>.
  - You can now cast uninhabited enums to integers.
  - You can now bind by reference and by move in patterns. This
    allows you to selectively borrow individual components of a type.
    E.g.

    #[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.
  - Added tier 2 support for aarch64-apple-darwin.
  - Added tier 2 support for aarch64-pc-windows-msvc.
  - Added tier 3 support for mipsel-unknown-none.
  - Raised the minimum supported LLVM version to LLVM 9.
  - Output from threads spawned in tests is now captured.
  - Change os and vendor values to "none" and "unknown" for some targets
  * Refer to Rust's platform support page for more information on Rust's
    tiered platform support.
  + Libraries
  - RangeInclusive now checks for exhaustion when calling contains and
    indexing.
  - ToString::to_string now no longer shrinks the internal buffer in
    the default implementation.
  - ops::{Index, IndexMut} are now implemented for fixed sized arrays
    of any length.
  + 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-tree now marks proc-macro crates.
  - Added CARGO_PRIMARY_PACKAGE build-time environment variable. 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.
  + Compatibility Notes
  - Demoted i686-unknown-freebsd from host tier 2 to target tier 2
    support.
  - Macros that end with a semi-colon are now treated as statements
    even if they expand to nothing.
  - Rustc will now check for the validity of some built-in attributes
    on enum variants. 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 for more details.
  - Trait bounds are no longer inferred for associated types.
  + 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.
  - Calculate visibilities once in resolve.
  - Added system to the llvm-libunwind bootstrap config option.
  - Added --color for configuring terminal color support to bootstrap.
- Rebased patches:
  + ignore-Wstring-conversion.patch (location)

Final SR - promised :)

- <https://github.com/rust-lang/rust/issues/74976>: Add "--stage 1"
  to the "./x.py doc" call to ensure the newly built compiler gets
  used.

-------------------------------------------------------------------
Sat Jan  9 09:25:07 UTC 2021 - Manfred Hollstein <manfred.h@gmx.net>

- Leap 15.3 does not provide a suitable llvm-devel package, hence
  explicitly require llvm9-devel. Details can be seen in the following
  e-mail thread
  <https://lists.opensuse.org/archives/list/factory@lists.opensuse.org/thread/ZQWAMG2VYBSI2BFM7G3H5YG26ALXWAOA/>

-------------------------------------------------------------------
Sun Jan  3 11:27:23 UTC 2021 - Manfred Hollstein <manfred.h@gmx.net>

- LLVM >= 9.0 is needed nowadays.
- Disable usage of "ninja" for all distributions older than Leap 15.2

-------------------------------------------------------------------
Sat Jan  2 16:50:47 UTC 2021 - Manfred Hollstein <manfred.h@gmx.net>

- Update to version 1.48.0
  + Language
  - The `unsafe` keyword is now syntactically permitted on modules.
    This is still rejected semantically, but can now be parsed by procedural
    macros.
  + Compiler
  - Stabilised the `-C link-self-contained=<yes|no>` compiler flag.
    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.
    Note: If you're using cargo you must explicitly pass the `--target` flag.
  - Added tier 2* support for aarch64-unknown-linux-musl.
  * Refer to Rust's platform support page for more information on Rust's
    tiered platform support.
  + Libraries
  - io::Write is now implemented for &ChildStdin &Sink, &Stdout, and &Stderr.
  - All arrays of any length now implement TryFrom<Vec<T>>.
  - The matches! macro now supports having a trailing comma.
  - Vec<A> now implements PartialEq<[B]> where A: PartialEq<B>.
  - The RefCell::{replace, replace_with, clone} methods now all use #[track_caller].
  + 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.
    E.g. /// Uses [`std::future`] will automatically generate a link to
    std::future's documentation. See "Linking to items by name" for more
    information.
  - You can now specify #[doc(alias = "<alias>")] on items to add search
    aliases when searching through rustdoc's UI.
  + Compatibility Notes
  - Promotion of references to 'static lifetime inside const fn now
    follows the same rules as inside a fn body. In particular, &foo()
    will not be promoted to 'static lifetime any more inside const fns.
  - Associated type bindings on trait objects are now verified to meet
    the bounds declared on the trait when checking that they implement
    the trait.
  - When trait bounds on associated types or opaque types are ambiguous,
    the compiler no longer makes an arbitrary choice on which bound to use.
  - Fixed recursive nonterminals not being expanded in macros during
    pretty-print/reparse check. 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.
  - rustc will now warn if you use attributes like #[link_name] or
    #[cold] in places where they have no effect.
  - Updated _mm256_extract_epi8 and _mm256_extract_epi16 signatures
    in arch::{x86, x86_64} to return i32 to match the vendor signatures.
  - mem::uninitialized will now panic if any inner types inside a struct
    or enum disallow zero-initialization.
  - #[target_feature] will now error if used in a place where it has no effect.
  - Foreign exceptions are now caught by catch_unwind and will cause an
    abort. 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.
    You can continue building with make by setting ninja=false in
    your config.toml.
  - cg_llvm: fewer_names in uncached_llvm_type
  - Made ensure_sufficient_stack() non-generic
- Rebased patches:
  + ignore-Wstring-conversion.patch (location)

1dcb483bf1 Accepting request 824719 from home:mrostecki:branches:devel:languages:rust
NOTE: The reason I made an update to 1.44.x instead od 1.45.x is that it's impossible to build 1.45.x with 1.43.x. We will be able to update to 1.45.x after we have 1.44.x compilers reeady.

- Update to version 1.44.1
  * rustfmt accepts rustfmt_skip in cfg_attr again.
  * Don't hash executable filenames on apple platforms, fixing backtraces.
  * Fix crashes when finding backtrace on macOS.
  * Clippy applies lint levels into different files.
- Update to version 1.44.0
  + Language
    - You can now use `async/.await` with `#[no_std]` enabled.
    - Added the `unused_braces` lint.
    - Expansion-driven outline module parsing
  + Compiler
    - Rustc now respects the `-C codegen-units` flag in incremental mode.
      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.
    - Added tier 3\* support for the `aarch64-unknown-none` and
      `aarch64-unknown-none-softfloat` targets.
    - Added tier 3 support for `arm64-apple-tvos` and
      `x86_64-apple-tvos` targets.
  + Libraries
    - Special cased `vec![]` to map directly to `Vec::new()`. This allows
      `vec![]` to be able to be used in `const` contexts.
    - `convert::Infallible` now implements `Hash`.
    - `OsString` now implements `DerefMut` and `IndexMut` returning
      a `&mut OsStr`.
    - Unicode 13 is now supported.
    - `String` now implements `From<&mut str>`.
    - `IoSlice` now implements `Copy`.
    - `Vec<T>` now implements `From<[T; N]>`. Where `N` is at most 32.

- Update to version 1.39.0
  + 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.
    - You can now use certain attributes on function, closure, and
      function pointer parameters.
    - You can now take shared references to bind-by-move patterns in
      the if guards of match arms.
  + Compiler
    - Added tier 3 support for the i686-unknown-uefi target.
    - Added tier 3 support for the sparc64-unknown-openbsd target.
    - rustc will now trim code snippets in diagnostics to fit in your
      terminal.
    - You can now pass --show-output argument to test binaries to
      print the output of successful tests.

- Patch: require patching of src/librustc_llvm/build.rs to ignore
  a flag that llvm-config --cxxflags outputs which GCC doesn't
  recognise.
- Default to building using the distro LLVM where the version is
  >= 5.0, instead of the Rust bundled LLVM which requires
  compilation. This should decrease build times. SLE LLVM is too old.
- Fixing various rpmlint warnings and errors:
  + ExclusiveArch instead of BuildArch for i686
  + Remove conflicts with same package name
  + Remove a few hidden files during prep, does not touch '.clang-format'
  + Remove old patch macro in comment
  + Fix lint warning about bash and zsh completition files
  + Fix various script shebang warnings (incorrect or missing)
  + Adjust rpmlintrc to mask some 'invalid' warnings
- Move Rust and its tools in to their own category under:
  + Development/Languages/Rust
- Jump from version 1.26.2 to 1.30.0 due to a build issue with using 1.26.x to
  compile 1.27.x. This package release requires %{rust_bootstrap} to be set.
- Enable extra rust tools to be built (cargo, rls, rustfmt, analysis)
    + cargo is now packaged with the same version number as the rust release, this
      may break any packages that relied on a cargo version number.
- Remove ccache and ninja from BuildRequires.
- Switch build configuration to use configure script, remove config.toml.
- Include all bootstraps in source rpm to make bootstrapping easier to manage
  within OBS.
- Remove unused patch: update-config-guess.patch
Update to version 1.30.0 (2018-10-25)
  + 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/5877]
    - `cargo doc` now supports `--message-format=json`.][cargo/5878] This is
      equivalent to calling `rustdoc --error-format=json`.
    - Cargo will now provide a progress bar for builds.][cargo/5995]
  + 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.
- Update to version 1.29.2 (2018-10-11)
  + Workaround for an aliasing-related LLVM bug, which caused miscompilation.
  + The `rls-preview` component on the windows-gnu targets has been restored.
- Update to version 1.29.1 (2018-09-25)
  + Security Notes
    - The standard library's `str::repeat` function contained an out of bounds write
      caused by an integer overflow. This has been fixed by deterministically
      panicking when an overflow happens.
- Update to version 1.29.0 (2018-09-13)
  + Compiler
    - Bumped minimum LLVM version to 5.0.
    - Added `powerpc64le-unknown-linux-musl` target.
    - Added `aarch64-unknown-hermit` and `x86_64-unknown-hermit` targets.
  + Libraries
    - `Once::call_once` no longer requires `Once` to be `'static`.
    - `BuildHasherDefault` now implements `PartialEq` and `Eq`.
    - `Box<CStr>`, `Box<OsStr>`, and `Box<Path>` now implement `Clone`.
    - Implemented `PartialEq<&str>` for `OsString` and `PartialEq<OsString>`
      for `&str`.
    - `Cell<T>` now allows `T` to be unsized.
    - `SocketAddr` is now stable on Redox.
  + Stabilized APIs
    - `Arc::downcast`
    - `Iterator::flatten`
    - `Rc::downcast`
  + Cargo
    - Cargo can silently fix some bad lockfiles.][cargo/5831] You can use
      `--locked` to disable this behavior.
    - `cargo-install` will now allow you to cross compile an install
      using `--target`.][cargo/5614]
    - Added the `cargo-fix` subcommand to automatically move project code from
      2015 edition to 2018.][cargo/5723]
    - `cargo doc` can now optionally document private types using the
      `--document-private-items` flag.][cargo/5543]
  + Misc
    - `rustdoc` now has the `--cap-lints` option which demotes all lints above
      the specified level to that level. For example `--cap-lints warn`
      will demote `deny` and `forbid` lints to `warn`.
    - `rustc` and `rustdoc` will now have the exit code of `1` if compilation
      fails and `101` if there is a panic.
    - A preview of clippy has been made available through rustup.
      You can install the preview with `rustup component add clippy-preview`.
  + Compatibility Notes
    - `str::{slice_unchecked, slice_unchecked_mut}` are now deprecated.
      Use `str::get_unchecked(begin..end)` instead.
    - `std::env::home_dir` is now deprecated for its unintuitive behavior.
      Consider using the `home_dir` function from
      https://crates.io/crates/dirs instead.
    - `rustc` will no longer silently ignore invalid data in target spec.
    - `cfg` attributes and `--cfg` command line flags are now more
      strictly validated.
- Update to version 1.28.0
  + Language
    - The `#[repr(transparent)]` attribute is now stable.-  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.- 
    - The `GlobalAlloc` trait and `#[global_allocator]` attribute are now
      stable.-  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 `()`.- 
    - The `lifetime` specifier for `macro_rules!` is now stable.-  This
      allows macros to easily target lifetimes.
  + Compiler
    - The `s` and `z` optimisation levels are now stable.-  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.-  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.- 
    - Reduced the number of allocations in the macro parser.-  This can
      improve compile times of macro heavy crates on average by 5%.
  + Libraries
    - Implemented `Default` for `&mut str`.- 
    - Implemented `From<bool>` for all integer and unsigned number types.- 
    - Implemented `Extend` for `()`.- 
    - The `Debug` implementation of `time::Duration` should now be more easily
      human readable.-  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`.- 
    - Implemented `Shl` and `Shr` for `Wrapping<u128>`
      and `Wrapping<i128>`.- 
    - `DirEntry::metadata` now uses `fstatat` instead of `lstat` when
      possible.-  This can provide up to a 40% speed increase.
    - Improved error messages when using `format!`.-

  + 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.-  This will allow dev tools to check whether a code suggestion
      would apply to them.
  + Compatibility Notes
    - Rust will consider trait objects with duplicated constraints to be the same
      type as without the duplicated constraint.-  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"); }
      }
- Update to version 1.27.2:
  + Compatibility Notes
    - The borrow checker was fixed to avoid an additional potential unsoundness when using
      match ergonomics
- Update to version 1.27.1:
  + Security Notes
    - 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. The associated CVE is [CVE-2018-1000622].
      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
- Update to version 1.27.0:
  + Language
    - Removed 'proc' from the reserved keywords list. This allows `proc` to
      be used as an identifier.
    - 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` because 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 `armvte-unknown-linux-musleabi` target.
  + Libraries
    - SIMD (Single Instruction Multiple Data) on x/x_ is now stable.
      This includes arch::x & arch::x_ modules which contain
      SIMD intrinsics, a new macro called `is_x_feature_detected!`, the
      `#[target_feature(enable="")]` attribute, and adding `target_feature = ""` to
      the `cfg` attribute.
    - A lot of methods for `[u]`, `f`, and `f` 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.
    - `cargo-metadata` now includes a package's `metadata` table.
    - 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 to false:
      `autobins`, `autobenches`, `autoexamples`, `autotests`.
    - Cargo will now cache compiler information. This can be disabled by
      setting `CARGO_CACHE_RUSTC_INFO=0` in your environment.
  + 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 2²⁹. Previously you
      could enter higher numbers but they were not supported by LLVM. Up to 512MB
      alignment should cover all use cases.
    - The `.description()` method on the `std::error::Error` trait
      has been soft-deprecated. It is no longer required to implement it.
  + Misc
    - Added “The Rustc book” into the official documentation.
