2015-01-05Stabilize core::opsAaron Turon-0/+70
This commit marks as stable those parts of `core::ops` that are in their final planned form: `Drop`, all of the mathematical operators (`Add`, `Sub`, etc), `Deref`/`DerefMut`. It leaves the `Index*`, `Slice*` and `Fn*` traits unstable, as they are still undergoing active changes.
2015-01-05Final alpha stabilization of core::iterAaron Turon-354/+340
This commit wraps up the adjustments to the iterator for recent language changes. * Moves `rposition` from `ExactSizeIterator` to `IteratorExt` using a `where` clause, thereby removing the `ExactSizeIterator: DoubleEndedIterator` constraint. * Merges `MutableDoubleEndedIterator` into `IteratorExt`, renaming `reverse_` to `reverse_in_place`. * Merges `IteratorOrdExt`, `IteratorCloneExt` and `CloneIteratorExt` into `IteratorExt` using `where` clauses. Marks as `#[stable]`: * the `iter` module itself * `FromIterator`, `Extend` * `Iterator`, `IteratorExt` * `map` * `filter` * `filter_map` * `skip_while` * `take_while` * `scan` * `flat_map` * `inspect` * `collect` * `fold` * `all` * `any` * `find` * `rposition` * `max`, `min` * Various adapter types related to the above methods Because of the trait merging, this is a: [breaking-change]
2015-01-05Rename macro_escape to macro_useKeegan McAllister-4/+8
In the future we want to support #[macro_use(foo, bar)] mod macros; but it's not an essential part of macro reform. Reserve the syntax for now.

In preparation for the rename.
2015-01-05Use $crate and macro reexport to reduce duplicated codeKeegan McAllister-23/+182
Many of libstd's macros are now re-exported from libcore and libcollections. Their libstd definitions have moved to a macros_stage0 module and can disappear after the next snapshot. Where the two crates had already diverged, I took the libstd versions as they're generally newer and better-tested. See e.g. d3c831b, which was a fix to libstd's assert_eq!() that didn't make it into libcore's. Fixes #16806.

2015-01-05std: Move Atomic{Int,Uint} back to unstableAlex Crichton-24/+6

2015-01-05std: Redesign c_str and c_vecAlex Crichton-1/+1
This commit is an implementation of [RFC 494][rfc] which removes the entire `std::c_vec` module and redesigns the `std::c_str` module as `std::ffi`. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0494-c_str-and-c_vec-stability.md The interface of the new `CString` is outlined in the linked RFC, the primary changes being: * The `ToCStr` trait is gone, meaning the `with_c_str` and `to_c_str` methods are now gone. These two methods are replaced with a `CString::from_slice` method. * The `CString` type is now just a wrapper around `Vec<u8>` with a static guarantee that there is a trailing nul byte with no internal nul bytes. This means that `CString` now implements `Deref<Target = [c_char]>`, which is where it gains most of its methods from. A few helper methods are added to acquire a slice of `u8` instead of `c_char`, as well as including a slice with the trailing nul byte if necessary. * All usage of non-owned `CString` values is now done via two functions inside of `std::ffi`, called `c_str_to_bytes` and `c_str_to_bytes_with_nul`. These functions are now the one method used to convert a `*const c_char` to a Rust slice of `u8`. Many more details, including newly deprecated methods, can be found linked in the RFC. This is a: [breaking-change] Closes #20444
2015-01-04std: Fix missing stability in syncAlex Crichton-13/+3
* The `sync` module is stable * The `sync::mpsc` module is stable * The `Sender::send` method is stable. * The `Once::doit` method is now removed. * Deprecated atomic initializers are removed. * Renamed atomic initializers are now stable.
2015-01-04std: Fixup some missing stabilization on strAlex Crichton-3/+7
* The `str` module itself is stable. * The `StrExt` trait is stable (and impls). * The `Utf8Error` type is unstable. * The `from_utf8` function is stable * Some iterators are now stable: * `Chars` * `CharIndices` * The `MatchIndices` iterator is now unstable * The public `traits` module is no longer public.
2015-01-05Change `&` pat to only work with &T, and `&mut` with &mut T.Huon Wilson-1/+1
This implements RFC 179 by making the pattern `&<pat>` require matching against a variable of type `&T`, and introducing the pattern `&mut <pat>` which only works with variables of type `&mut T`. The pattern `&mut x` currently parses as `&(mut x)` i.e. a pattern match through a `&T` or a `&mut T` that binds the variable `x` to have type `T` and to be mutable. This should be rewritten as follows, for example, for &mut x in slice.iter() { becomes for &x in slice.iter() { let mut x = x; Due to this, this is a [breaking-change] Closes #20496.

2015-01-03Remove deprecated functionalityAlex Crichton-839/+132
This removes a large array of deprecated functionality, regardless of how recently it was deprecated. The purpose of this commit is to clean out the standard libraries and compiler for the upcoming alpha release. Some notable compiler changes were to enable warnings for all now-deprecated command line arguments (previously the deprecated versions were silently accepted) as well as removing deriving(Zero) entirely (the trait was removed). The distribution no longer contains the libtime or libregex_macros crates. Both of these have been deprecated for some time and are available externally.

closes #20486 closes #20474 closes #20441 [breaking-change] The `Index[Mut]` traits now have one less input parameter, as the return type of the indexing operation is an associated type. This breaks all existing implementations. --- binop traits (`Add`, `Sub`, etc) now have an associated type for their return type. Also, the RHS input parameter now defaults to `Self` (except for the `Shl` and `Shr` traits). For example, the `Add` trait now looks like this: ``` rust trait Add<Rhs=Self> { type Output; fn add(self, Rhs) -> Self::Output; } ``` The `Neg` and `Not` traits now also have an associated type for their return type. This breaks all existing implementations of these traits. --- Affected traits: - `Iterator { type Item }` - `IteratorExt` no input/output types, uses `<Self as Iterator>::Item` in its methods - `DoubleEndedIterator` no input/output types, uses `<Self as Iterator>::Item` in its methods - `DoubleEndedIteratorExt` no input/output types, uses `<Self as Iterator>::Item` in its methods - `RandomAccessIterator` no input/output types - `ExactSizeIterator` no input/output types, uses `<Self as Iterator>::Item` in its methods This breaks all the implementations of these traits.

2015-01-03auto merge of #20154 : P1start/rust/qualified-assoc-type-generics, ↵bors-8/+8
r=nikomatsakis This modifies `Parser::eat_lt` to always split up `<<`s, instead of doing so only when a lifetime name followed or the `force` parameter (now removed) was `true`. This is because `Foo<<TYPE` is now a valid start to a type, whereas previously only `Foo<<LIFETIME` was valid. This is a [breaking-change]. Change code that looks like this: ```rust let x = foo as bar << 13; ``` to use parentheses, like this: ```rust let x = (foo as bar) << 13; ``` Closes #17362.
2015-01-03auto merge of #19835 : pythonesque/rust/add-unordered-intrinsic, r=thestingerbors-0/+2
This corresponds to the JMM memory model's non-volatile reads and writes to shared variables. It provides fairly weak guarantees, but prevents UB (specifically, you will never see a value that was not written _at some point_ to the provided location). It is not part of the C++ memory model and is only legal to provide to LLVM for loads and stores (not fences, atomicrmw, etc.). Valid uses of this ordering are things like racy counters where you don't care about the operation actually being atomic, just want to avoid UB. It cannot be used for synchronization without additional memory barriers since unordered loads and stores may be reordered freely by the optimizer (this is the main way it differs from relaxed). Because it is new to Rust and it provides so few guarantees, for now only the intrinsic is provided--this patch doesn't add it to any of the higher-level atomic wrappers.

2015-01-02std: Stabilize the prelude moduleAlex Crichton-58/+55
This commit is an implementation of [RFC 503][rfc] which is a stabilization story for the prelude. Most of the RFC was directly applied, removing reexports. Some reexports are kept around, however: * `range` remains until range syntax has landed to reduce churn. * `Path` and `GenericPath` remain until path reform lands. This is done to prevent many imports of `GenericPath` which will soon be removed. * All `io` traits remain until I/O reform lands so imports can be rewritten all at once to `std::io::prelude::*`. This is a breaking change because many prelude reexports have been removed, and the RFC can be consulted for the exact list of removed reexports, as well as to find the locations of where to import them. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0503-prelude-stabilization.md [breaking-change] Closes #20068
2015-01-01std: Enforce Unicode in fmt::WriterAlex Crichton-49/+46
This commit is an implementation of [RFC 526][rfc] which is a change to alter the definition of the old `fmt::FormatWriter`. The new trait, renamed to `Writer`, now only exposes one method `write_str` in order to guarantee that all implementations of the formatting traits can only produce valid Unicode. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0526-fmt-text-writer.md One of the primary improvements of this patch is the performance of the `.to_string()` method by avoiding an almost-always redundant UTF-8 check. This is a breaking change due to the renaming of the trait as well as the loss of the `write` method, but migration paths should be relatively easy: * All usage of `write` should move to `write_str`. If truly binary data was being written in an implementation of `Show`, then it will need to use a different trait or an altogether different code path. * All usage of `write!` should continue to work as-is with no modifications. * All usage of `Show` where implementations just delegate to another should continue to work as-is. [breaking-change] Closes #20352
2015-01-01std: Second pass stabilization of syncAlex Crichton-3/+15
This pass performs a second pass of stabilization through the `std::sync` module, avoiding modules/types that are being handled in other PRs (e.g. mutexes, rwlocks, condvars, and channels). The following items are now stable * `sync::atomic` * `sync::atomic::ATOMIC_BOOL_INIT` (was `INIT_ATOMIC_BOOL`) * `sync::atomic::ATOMIC_INT_INIT` (was `INIT_ATOMIC_INT`) * `sync::atomic::ATOMIC_UINT_INIT` (was `INIT_ATOMIC_UINT`) * `sync::Once` * `sync::ONCE_INIT` * `sync::Once::call_once` (was `doit`) * C == `pthread_once(..)` * Boost == `call_once(..)` * Windows == `InitOnceExecuteOnce` * `sync::Barrier` * `sync::Barrier::new` * `sync::Barrier::wait` (now returns a `bool`) * `sync::Semaphore::new` * `sync::Semaphore::acquire` * `sync::Semaphore::release` The following items remain unstable * `sync::SemaphoreGuard` * `sync::Semaphore::access` - it's unclear how this relates to the poisoning story of mutexes. * `sync::TaskPool` - the semantics of a failing task and whether a thread is re-attached to a thread pool are somewhat unclear, and the utility of this type in `sync` is question with respect to the jobs of other primitives. This type will likely become stable or move out of the standard library over time. * `sync::Future` - futures as-is have yet to be deeply re-evaluated with the recent core changes to Rust's synchronization story, and will likely become stable in the future but are unstable until that time comes.
