2016-02-01docs: Standardize on 'Errors' header in std docsKamal Marhubi-6/+6
2016-01-30Change MutexGuard and RwLockWriteGuard to store &mut T not &UnsafeCell<T>Jonathan Reem-20/+27
This centralizes the unsafety of converting from UnsafeCell<T> to &mut T.
2016-01-29Add guard map methods for transforming guards to contain sub-borrows.Jonathan Reem-4/+86
This is very useful when the lock is synchronizing access to a data structure and you would like to return or store guards which contain references to data inside the data structure instead of the data structure itself.
2015-12-05std: Stabilize APIs for the 1.6 releaseAlex Crichton-2/+2
This commit is the standard API stabilization commit for the 1.6 release cycle. The list of issues and APIs below have all been through their cycle-long FCP and the libs team decisions are listed below Stabilized APIs * `Read::read_exact` * `ErrorKind::UnexpectedEof` (renamed from `UnexpectedEOF`) * libcore -- this was a bit of a nuanced stabilization, the crate itself is now marked as `#[stable]` and the methods appearing via traits for primitives like `char` and `str` are now also marked as stable. Note that the extension traits themeselves are marked as unstable as they're imported via the prelude. The `try!` macro was also moved from the standard library into libcore to have the same interface. Otherwise the functions all have copied stability from the standard library now. * The `#![no_std]` attribute * `fs::DirBuilder` * `fs::DirBuilder::new` * `fs::DirBuilder::recursive` * `fs::DirBuilder::create` * `os::unix::fs::DirBuilderExt` * `os::unix::fs::DirBuilderExt::mode` * `vec::Drain` * `vec::Vec::drain` * `string::Drain` * `string::String::drain` * `vec_deque::Drain` * `vec_deque::VecDeque::drain` * `collections::hash_map::Drain` * `collections::hash_map::HashMap::drain` * `collections::hash_set::Drain` * `collections::hash_set::HashSet::drain` * `collections::binary_heap::Drain` * `collections::binary_heap::BinaryHeap::drain` * `Vec::extend_from_slice` (renamed from `push_all`) * `Mutex::get_mut` * `Mutex::into_inner` * `RwLock::get_mut` * `RwLock::into_inner` * `Iterator::min_by_key` (renamed from `min_by`) * `Iterator::max_by_key` (renamed from `max_by`) Deprecated APIs * `ErrorKind::UnexpectedEOF` (renamed to `UnexpectedEof`) * `OsString::from_bytes` * `OsStr::to_cstring` * `OsStr::to_bytes` * `fs::walk_dir` and `fs::WalkDir` * `path::Components::peek` * `slice::bytes::MutableByteVector` * `slice::bytes::copy_memory` * `Vec::push_all` (renamed to `extend_from_slice`) * `Duration::span` * `IpAddr` * `SocketAddr::ip` * `Read::tee` * `io::Tee` * `Write::broadcast` * `io::Broadcast` * `Iterator::min_by` (renamed to `min_by_key`) * `Iterator::max_by` (renamed to `max_by_key`) * `net::lookup_addr` New APIs (still unstable) * `<[T]>::sort_by_key` (added to mirror `min_by_key`) Closes #27585 Closes #27704 Closes #27707 Closes #27710 Closes #27711 Closes #27727 Closes #27740 Closes #27744 Closes #27799 Closes #27801 cc #27801 (doesn't close as `Chars` is still unstable) Closes #28968
2015-11-18Add missing annotations and some testsVadim Petrochenkov-0/+4
2015-10-16Add `Shared` pointer and have `{Arc, Rc}` use itAndrew Paseltiner-0/+1
This change has two consequences: 1. It makes `Arc<T>` and `Rc<T>` covariant in `T`. 2. It causes the compiler to reject code that was unsound with respect to dropck. See compile-fail/issue-29106.rs for an example of code that no longer compiles. Because of this, this is a [breaking-change]. Fixes #29037. Fixes #29106.

2015-06-17std: Stabilize the sync_poison featureAlex Crichton-1/+1
These accessor/constructor methods for a `PoisonError` are quite standard for a wrapper type and enable manipulation of the underlying type.

2015-05-09Squeeze the last bits of `task`s in documentation in favor of `thread`Barosl Lee-1/+1
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.
2015-05-06Update documentation for RwLock::try_{read,write}.John Gallagher-10/+17
2015-05-06Make RwLock::try_write try to obtain a write lockJohn Gallagher-2/+19
2015-05-02Make `UnsafeCell`, `RefCell`, `Mutex`, and `RwLock` accept DSTsP1start-19/+34
This + DST coercions (#24619) would allow code like `Rc<RefCell<Box<Trait>>>` to be simplified to `Rc<RefCell<Trait>>`.

2015-04-08Implement reentrant mutexes and make stdio use themSimonas Kazlauskas-2/+2
write_fmt calls write for each formatted field. The default implementation of write_fmt is used, which will call write on not-yet-locked stdout (and write locking after), therefore making print! in multithreaded environment still interleave contents of two separate prints. This patch implements reentrant mutexes, changes stdio handles to use these mutexes and overrides write_fmt to lock the stdio handle for the whole duration of the call.

2015-03-08Remove unneeded `Send`/`Sync` bounds from `Mutex`/`RwLock`.Huon Wilson-2/+2
The requirements `T: Send` and `T: Send + Sync` for `Mutex` and `RwLock` respectively only matter if those types are shared/sent across thread boundaries, and that is adequately controlled by the impls of `Send`/`Sync` for them. If `T` doesn't satisfy the bounds, then the types cannot cross thread boundaries and so everything is still safe (the two types just act like an expensive `RefCell`).
2015-03-02Use `const`s instead of `static`s where appropriateFlorian Zeitz-2/+2
This changes the type of some public constants/statics in libunicode. Notably some `&'static &'static [(char, char)]` have changed to `&'static [(char, char)]`. The regexp crate seems to be the sole user of these, yet this is technically a [breaking-change]
2015-02-27Auto merge of #22573 - nwin:impl-debug-rwlock-weak, r=Manishearthbors-0/+14
Implements `Debug` for `RwLock` and `arc::Weak` in the same way it is implemented for `rc::Weak` (basically copy & paste). The lack of this implementation prevents the automatic implementation of `Debug` for structs containing members of these types.

2015-02-25Rollup merge of #22596 - alexcrichton:fix-some-impls, r=huonwManish Goregaokar-3/+0
This commit removes many unnecessary `unsafe impl` blocks as well as pushing the needed implementations to the lowest level possible. I noticed that the bounds for `RwLock` are a little off when reviewing #22574 and wanted to ensure that we had our story straight on these implementations.
2015-02-21Remove `'static` bound from sync::mpsc, Mutex and RwLock.Huon Wilson-2/+2
Adds some basic tests to check that the types still catch the most glaring errors that could occur. cc #22444.

Use [`rand`](https://crates.io/crates/rand) and [`derive_rand`](https://crates.io/crates/derive_rand) from crates.io. [breaking-change]
2015-02-04Deprecate in-tree `rand`, `std::rand` and `#[derive(Rand)]`.Huon Wilson-0/+2
Use the crates.io crate `rand` (version 0.1 should be a drop in replacement for `std::rand`) and `rand_macros` (`#[derive_Rand]` should be a drop-in replacement). [breaking-change]
