Avoid sh invocation for simple ldconfig calls. Drop archaic %clean section. Drop filler words from summary. - Rename source package to rustc-1_9 to conform to naming standards. - Rename source package to rustc-190 to avoid unecessary rebuilds of rustc packages on upgrade - Move stage0 binaries into separate package - Disable embedding timestamp information - Add 0003-Disable-embedding-timestamp-information.patch - Rename package to rustc-stable - Add rpmlintrc - Make bootstrapping conditional - Fix misleading indentation errors on GCC 6.0 - Remove snap2.sh - Add 0001-Fix-misleading-intentation-errors-on-gcc-6.0.patch - Add 0002-Fix-GCC-6-misleading-indentation-error-in-hoedown.patch - Update to version 1.9.0 + Stabilization of std::panic + Deprecation warnings, #[deprecated] attribute + Compile time improvements + Rolling out use of specialization + Library stabilizations About 80 library functions and methods are now stable in 1. + http://blog.rust-lang.org/2016/05/26/Rust-1.9.html - Update to version 1.8.0: + Various “operator equals” operators, such as += and -=, are now overloadable via various traits. + Empty struct declaration can contain cutly braces + New (non default) cargo based build system for rustc + About 20 library functions and methods are now stable in 1.8 - Update to version 1.7.0: + Many stabilized APIs + Improved library performance + BTreeSet and its iterators, Iter, IntoIter, and Range are covariant over their contained type. + LinkedList and its iterators, Iter and IntoIter are covariant over their contained type. + str::replace now accepts a Pattern, like other string searching methods. + Any is implemented for unsized types. + Hash is implemented for Duration. + Soundness fixes, may break code. See RFC 1214 for more information. + Several bugs in the compiler's visibility calculations were fixed. + Parsing "." as a float results in an error instead of 0. + Borrows of closure parameters may not outlive the closure. - Update to version 1.6.0: + Stabilization of libcore and other library functions + Crates.io disallows wildcards - Update to version 1.4.0: + Several changes have been made to fix type soundness and improve the behavior of associated types. See RFC 1214. Although we have mostly introduced these changes as warnings this release, to become errors next release, there are still some scenarios that will see immediate breakage. + The str::lines and BufRead::lines iterators treat \r\n as line breaks in addition to \n. + Loans of 'static lifetime extend to the end of a function. + str::parse no longer introduces avoidable rounding error when parsing floating point numbers.

Representative crates include hyper (compiles 1.16x faster), html5ever (1.62x faster), regex (1.32x faster) and rust-encoding (1.35x faster). You can explore some of this performance data at Nick Cameron’s preliminary tracking site, using dates 2015-05-15 to 2015-06-25. + Parallel codegen is now working, and produces a 33% speedup when bootstrapping on a 4 core machine. Parallel codegen is particularly useful for debug builds, since it prevents some optimizations; but it can also be used with optimizations as an effective -O1 flag. It can be activated by passing -C codegen-units=N to rustc, where N is the desired number of threads. - Update to version 1.1.0: + The std::fs module has been expanded to expand the set of functionality exposed: * DirEntry now supports optimizations like file_type and metadata which don't incur a syscall on some platforms. * A symlink_metadata function has been added. * The fs::Metadata structure now lowers to its OS counterpart, providing access to all underlying information. + The compiler now contains extended explanations of many errors.

Accepting request 646330 from home:luke_nukem:branches:devel:languages:rust - 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!`.- + Stabilized APIs - `Iterator::step_by` - `Path::ancestors` - `SystemTime::UNIX_EPOCH` - `alloc::GlobalAlloc` - `alloc::Layout` - `alloc::LayoutErr` - `alloc::System` - `alloc::alloc` - `alloc::alloc_zeroed` - `alloc::dealloc` - `alloc::realloc` - `alloc::handle_alloc_error` - `btree_map::Entry::or_default` - `fmt::Alignment` - `hash_map::Entry::or_default` - `iter::repeat_with` - `num::NonZeroUsize` - `num::NonZeroU128` - `num::NonZeroU16` - `num::NonZeroU32` - `num::NonZeroU64` - `num::NonZeroU8` - `ops::RangeBounds` - `slice::SliceIndex` - `slice::from_mut` - `slice::from_ref` - `{Any + Send + Sync}::downcast_mut` - `{Any + Send + Sync}::downcast_ref` - `{Any + Send + Sync}::is` + 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. + Stabilized APIs - DoubleEndedIterator::rfind - DoubleEndedIterator::rfold - DoubleEndedIterator::try_rfold - Duration::from_micros - Duration::from_nanos - Duration::subsec_micros - Duration::subsec_millis - HashMap::remove_entry - Iterator::try_fold - Iterator::try_for_each - NonNull::cast - Option::filter - String::replace_range - Take::set_limit - hint::unreachable_unchecked - os::unix::process::parent_id - ptr::swap_nonoverlapping - slice::rsplit_mut - slice::rsplit - slice::swap_with_slice + 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.

Avoid sh invocation for simple ldconfig calls. Drop archaic %clean section. Drop filler words from summary. - Rename source package to rustc-1_9 to conform to naming standards. - Rename source package to rustc-190 to avoid unecessary rebuilds of rustc packages on upgrade - Move stage0 binaries into separate package - Disable embedding timestamp information - Add 0003-Disable-embedding-timestamp-information.patch - Rename package to rustc-stable - Add rpmlintrc - Make bootstrapping conditional - Fix misleading indentation errors on GCC 6.0 - Remove snap2.sh - Add 0001-Fix-misleading-intentation-errors-on-gcc-6.0.patch - Add 0002-Fix-GCC-6-misleading-indentation-error-in-hoedown.patch - Update to version 1.9.0 + Stabilization of std::panic + Deprecation warnings, #[deprecated] attribute + Compile time improvements + Rolling out use of specialization + Library stabilizations About 80 library functions and methods are now stable in 1. + http://blog.rust-lang.org/2016/05/26/Rust-1.9.html - Update to version 1.8.0: + Various “operator equals” operators, such as += and -=, are now overloadable via various traits. + Empty struct declaration can contain cutly braces + New (non default) cargo based build system for rustc + About 20 library functions and methods are now stable in 1.8 - Update to version 1.7.0: + Many stabilized APIs + Improved library performance + BTreeSet and its iterators, Iter, IntoIter, and Range are covariant over their contained type. + LinkedList and its iterators, Iter and IntoIter are covariant over their contained type. + str::replace now accepts a Pattern, like other string searching methods. + Any is implemented for unsized types. + Hash is implemented for Duration. + Soundness fixes, may break code. See RFC 1214 for more information. + Several bugs in the compiler's visibility calculations were fixed. + Parsing "." as a float results in an error instead of 0. + Borrows of closure parameters may not outlive the closure. - Update to version 1.6.0: + Stabilization of libcore and other library functions + Crates.io disallows wildcards - Update to version 1.4.0: + Several changes have been made to fix type soundness and improve the behavior of associated types. See RFC 1214. Although we have mostly introduced these changes as warnings this release, to become errors next release, there are still some scenarios that will see immediate breakage. + The str::lines and BufRead::lines iterators treat \r\n as line breaks in addition to \n. + Loans of 'static lifetime extend to the end of a function. + str::parse no longer introduces avoidable rounding error when parsing floating point numbers.

Representative crates include hyper (compiles 1.16x faster), html5ever (1.62x faster), regex (1.32x faster) and rust-encoding (1.35x faster). You can explore some of this performance data at Nick Cameron’s preliminary tracking site, using dates 2015-05-15 to 2015-06-25. + Parallel codegen is now working, and produces a 33% speedup when bootstrapping on a 4 core machine. Parallel codegen is particularly useful for debug builds, since it prevents some optimizations; but it can also be used with optimizations as an effective -O1 flag. It can be activated by passing -C codegen-units=N to rustc, where N is the desired number of threads. - Update to version 1.1.0: + The std::fs module has been expanded to expand the set of functionality exposed: * DirEntry now supports optimizations like file_type and metadata which don't incur a syscall on some platforms. * A symlink_metadata function has been added. * The fs::Metadata structure now lowers to its OS counterpart, providing access to all underlying information. + The compiler now contains extended explanations of many errors. When an error with an explanation occurs the compiler suggests using the --explain flag to read the explanation. Error explanations are also available online. + Thanks to multiple improvements to type checking, as well as other work, the time to bootstrap the compiler decreased by 32%. - drop tar_scm service and use source urls - Update to version 1.0.0: + lint: deny transmuting from immutable to mutable, since it's undefined behavior + std: update select internals to not use mutable transmuting + std: Remove index notation on slice iterators + std: Destabilize io::BufStream + Make RwLock::try_write try to obtain a write lock + std: Remove addition on vectors for now + thread: right now you can't actually set those printers + Fix #24872, XSS in docs not found page. + Update AUTHORS.txt and RELEASES.md for 1.0 + std: Mark `mem::forget` as a safe function + core: impl AsRef<[u8]> for str + collections: impl AsRef<[u8]> for String + collections: change bounds of SliceConcatExt implementations to use Borrow instead of AsRef + Fix invalid references due to the automated string substitution + dropck: must assume `Box<Trait + 'a>` has a destructor of interest. - Rename binary package to rust - Add build for i586 - Only run fdupes on SUSE builds - Changed version format - Update to version 1.0.0~beta4+git.1430848988.f873dc5: + Introduce a `FreeRegionMap` data structure.

Accepting request 646330 from home:luke_nukem:branches:devel:languages:rust - 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!`.- + Stabilized APIs - `Iterator::step_by` - `Path::ancestors` - `SystemTime::UNIX_EPOCH` - `alloc::GlobalAlloc` - `alloc::Layout` - `alloc::LayoutErr` - `alloc::System` - `alloc::alloc` - `alloc::alloc_zeroed` - `alloc::dealloc` - `alloc::realloc` - `alloc::handle_alloc_error` - `btree_map::Entry::or_default` - `fmt::Alignment` - `hash_map::Entry::or_default` - `iter::repeat_with` - `num::NonZeroUsize` - `num::NonZeroU128` - `num::NonZeroU16` - `num::NonZeroU32` - `num::NonZeroU64` - `num::NonZeroU8` - `ops::RangeBounds` - `slice::SliceIndex` - `slice::from_mut` - `slice::from_ref` - `{Any + Send + Sync}::downcast_mut` - `{Any + Send + Sync}::downcast_ref` - `{Any + Send + Sync}::is` + 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. + Stabilized APIs - DoubleEndedIterator::rfind - DoubleEndedIterator::rfold - DoubleEndedIterator::try_rfold - Duration::from_micros - Duration::from_nanos - Duration::subsec_micros - Duration::subsec_millis - HashMap::remove_entry - Iterator::try_fold - Iterator::try_for_each - NonNull::cast - Option::filter - String::replace_range - Take::set_limit - hint::unreachable_unchecked - os::unix::process::parent_id - ptr::swap_nonoverlapping - slice::rsplit_mut - slice::rsplit - slice::swap_with_slice + 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.
