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]

2014-12-29std: Second pass stabilization for `comm`Alex Crichton-0/+2079
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]
