2015-08-17core: Move `atomic` into a new `sync` moduleAlex Crichton-1113/+0
This mirrors the same hierarchy in the standard library.
2015-07-30Auto merge of #27052 - wthrowe:atomic_send, r=Gankrobors-1/+2
I think this was just missed when `Send` and `Sync` were redone, since it seems odd to not be able to use things like `Arc<AtomicPtr>`. If it was intentional feel free to just close this. I used another test as a template for writing mine, so I hope I got all the headers and stuff right.
2015-07-29Fix a documentation bug for memory orderingsJeehoon Kang-1/+1
As described in the module documentation, the memory orderings in Rust are the same with that of LLVM. However, the documentation for the memory orderings enum says the memory orderings are the same of that of C++. Note that they differ in that C++'s support the consume reads, while LLVM's does not. Hence this commit fixes the bug in the documentation for the enum.

This appears to have just been an oversight, and it is annoying to not be able to use an Arc<AtomicPtr>.

2015-06-29Refine Atomic*::compare_and_swap documentationSimonas Kazlauskas-23/+23
Namely: * Change parameter `old` to read `current` so it is clearer what the argument refers to (originally suggested `expected`, but shot down by Steve); * Add some formatting and fix some mistakes like referring to the method as `swap` rather than `compare_and_swap`.

Swap arguments of `assert_eq!` calls, insert additional assertions here and there. Closes #26169.

2015-05-09Squeeze the last bits of `task`s in documentation in favor of `thread`Barosl Lee-5/+5
An automated script was run against the `.rs` and `.md` files, subsituting every occurrence of `task` with `thread`. In the `.rs` files, only the texts in the comment blocks were affected.

2015-03-31std: Clean out #[deprecated] APIsAlex Crichton-141/+0
This commit cleans out a large amount of deprecated APIs from the standard library and some of the facade crates as well, updating all users in the compiler and in tests as it goes along.

2015-03-02Enable recursion for visit_ty in lint visitorIvan Petkov-0/+2
* The lint visitor's visit_ty method did not recurse, and had a reference to the now closed #10894 * The newly enabled recursion has only affected the `deprectated` lint which now detects uses of deprecated items in trait impls and function return types * Renamed some references to `CowString` and `CowVec` to `Cow<str>` and `Cow<[T]>`, respectively, which appear outside of the crate which defines them * Replaced a few instances of `InvariantType<T>` with `PhantomData<Cell<T>>` * Disabled the `deprecated` lint in several places that reference/implement traits on deprecated items which will get cleaned up in the future * Disabled the `exceeding_bitshifts` lint for compile-fail/huge-array-simple test so it doesn't shadow the expected error on 32bit systems * Unfortunately, this means that if a library declares `#![deny(deprecated)]` and marks anything as deprecated, it will have to disable the lint for any uses of said item, e.g. any impl the now deprecated item For any library that denies deprecated items but has deprecated items of its own, this is a [breaking-change]

2015-01-30std: Stabilize Atomic{Isize,Usize} methodsAlex Crichton-0/+20
These methods were intended to be stable as of #16258 but the tags have since been lost in various refactorings. This commit re-adds the `#[stable]` attributes to each of these functions.

2015-01-06rollup merge of #20615: aturon/stab-2-threadAlex Crichton-1/+1
This commit takes a first pass at stabilizing `std::thread`: * It removes the `detach` method in favor of two constructors -- `spawn` for detached threads, `scoped` for "scoped" (i.e., must-join) threads. This addresses some of the surprise/frustrating debug sessions with the previous API, in which `spawn` produced a guard that on destruction joined the thread (unless `detach` was called). The reason to have the division in part is that `Send` will soon not imply `'static`, which means that `scoped` thread creation can take a closure over *shared stack data* of the parent thread. On the other hand, this means that the parent must not pop the relevant stack frames while the child thread is running. The `JoinGuard` is used to prevent this from happening by joining on drop (if you have not already explicitly `join`ed.) The APIs around `scoped` are future-proofed for the `Send` changes by taking an additional lifetime parameter. With the current definition of `Send`, this is forced to be `'static`, but when `Send` changes these APIs will gain their full flexibility immediately. Threads that are `spawn`ed, on the other hand, are detached from the start and do not yield an RAII guard. The hope is that, by making `scoped` an explicit opt-in with a very suggestive name, it will be drastically less likely to be caught by a surprising deadlock due to an implicit join at the end of a scope. * The module itself is marked stable. * Existing methods other than `spawn` and `scoped` are marked stable. The migration path is: ```rust Thread::spawn(f).detached() ``` becomes ```rust Thread::spawn(f) ``` while ```rust let res = Thread::spawn(f); res.join() ``` becomes ```rust let res = Thread::scoped(f); res.join() ``` [breaking-change]

2015-01-03Remove deprecated functionalityAlex Crichton-60/+118
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.

2015-01-01std: Second pass stabilization of syncAlex Crichton-3/+13
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.
