2015-02-17Revise std::thread semanticsAaron Turon-107/+263
This commit makes several changes to `std::thread` in preparation for final stabilization: * It removes the ability to handle panics from `scoped` children; see #20807 for discussion * It adds a `JoinHandle` structure, now returned from `spawn`, which makes it possible to join on children that do not share data from their parent's stack. The child is automatically detached when the handle is dropped, and the handle cannot be copied due to Posix semantics. * It moves all static methods from `std::thread::Thread` to free functions in `std::thread`. This was done in part because, due to the above changes, there are effectively no direct `Thread` constructors, and the static methods have tended to feel a bit awkward. * Adds an `io::Result` around the `Builder` methods `scoped` and `spawn`, making it possible to handle OS errors when creating threads. The convenience free functions entail an unwrap. * Stabilizes the entire module. Despite the fact that the API is changing somewhat here, this is part of a long period of baking and the changes are addressing all known issues prior to alpha2. If absolutely necessary, further breaking changes can be made prior to beta. Closes #20807 [breaking-change]
2015-02-18Add missing marker to std::thread::JoinGuard.Huon Wilson-1/+3
The lifetime was previously, incorrectly unconstrained.
2015-02-18Update the libraries to reflect Send loosing the 'static bound.Huon Wilson-7/+7
In most places this preserves the current API by adding an explicit `'static` bound. Notably absent are some impls like `unsafe impl<T: Send> Send for Foo<T>` and the `std::thread` module. It is likely that it will be possible to remove these after auditing the code to ensure restricted lifetimes are safe. More progress on #22251.

2015-01-20std: Rename Show/String to Debug/DisplayAlex Crichton-6/+6
This commit is an implementation of [RFC 565][rfc] which is a stabilization of the `std::fmt` module and the implementations of various formatting traits. Specifically, the following changes were performed: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0565-show-string-guidelines.md * The `Show` trait is now deprecated, it was renamed to `Debug` * The `String` trait is now deprecated, it was renamed to `Display` * Many `Debug` and `Display` implementations were audited in accordance with the RFC and audited implementations now have the `#[stable]` attribute * Integers and floats no longer print a suffix * Smart pointers no longer print details that they are a smart pointer * Paths with `Debug` are now quoted and escape characters * The `unwrap` methods on `Result` now require `Display` instead of `Debug` * The `Error` trait no longer has a `detail` method and now requires that `Display` must be implemented. With the loss of `String`, this has moved into libcore. * `impl<E: Error> FromError<E> for Box<Error>` now exists * `derive(Show)` has been renamed to `derive(Debug)`. This is not currently warned about due to warnings being emitted on stage1+ While backwards compatibility is attempted to be maintained with a blanket implementation of `Display` for the old `String` trait (and the same for `Show`/`Debug`) this is still a breaking change due to primitives no longer implementing `String` as well as modifications such as `unwrap` and the `Error` trait. Most code is fairly straightforward to update with a rename or tweaks of method calls. [breaking-change] Closes #21436

2015-01-08Improvements to feature stagingBrian Anderson-3/+3
This gets rid of the 'experimental' level, removes the non-staged_api case (i.e. stability levels for out-of-tree crates), and lets the staged_api attributes use 'unstable' and 'deprecated' lints. This makes the transition period to the full feature staging design a bit nicer.

2015-01-06rollup merge of #20615: aturon/stab-2-threadAlex Crichton-65/+133
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-7/+0
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.

2015-01-02std: Stabilize the prelude moduleAlex Crichton-2/+4
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

2014-12-29std: Second pass stabilization for `comm`Alex Crichton-9/+9
This commit is a second pass stabilization for the `std::comm` module, performing the following actions: * The entire `std::comm` module was moved under `std::sync::mpsc`. This movement reflects that channels are just yet another synchronization primitive, and they don't necessarily deserve a special place outside of the other concurrency primitives that the standard library offers. * The `send` and `recv` methods have all been removed. * The `send_opt` and `recv_opt` methods have been renamed to `send` and `recv`. This means that all send/receive operations return a `Result` now indicating whether the operation was successful or not. * The error type of `send` is now a `SendError` to implement a custom error message and allow for `unwrap()`. The error type contains an `into_inner` method to extract the value. * The error type of `recv` is now `RecvError` for the same reasons as `send`. * The `TryRecvError` and `TrySendError` types have had public reexports removed of their variants and the variant names have been tweaked with enum namespacing rules. * The `Messages` iterator is renamed to `Iter` This functionality is now all `#[stable]`: * `Sender` * `SyncSender` * `Receiver` * `std::sync::mpsc` * `channel` * `sync_channel` * `Iter` * `Sender::send` * `Sender::clone` * `SyncSender::send` * `SyncSender::try_send` * `SyncSender::clone` * `Receiver::recv` * `Receiver::try_recv` * `Receiver::iter` * `SendError` * `RecvError` * `TrySendError::{mod, Full, Disconnected}` * `TryRecvError::{mod, Empty, Disconnected}` * `SendError::into_inner` * `TrySendError::into_inner` This is a breaking change due to the modification of where this module is located, as well as the changing of the semantics of `send` and `recv`. Most programs just need to rename imports of `std::comm` to `std::sync::mpsc` and add calls to `unwrap` after a send or a receive operation. [breaking-change]
