2015-01-06core: split into fmt::Show and fmt::StringSean McArthur-9/+9
fmt::Show is for debugging, and can and should be implemented for all public types. This trait is used with `{:?}` syntax. There still exists #[derive(Show)]. fmt::String is for types that faithfully be represented as a String. Because of this, there is no way to derive fmt::String, all implementations must be purposeful. It is used by the default format syntax, `{}`. This will break most instances of `{}`, since that now requires the type to impl fmt::String. In most cases, replacing `{}` with `{:?}` is the correct fix. Types that were being printed specifically for users should receive a fmt::String implementation to fix this. Part of #20013 [breaking-change]

2015-01-06Tuning pthread_key_t typeMichael Neumann-2/+10
Both FreeBSD and DragonFly define pthread_key_t as int, while Linux defines it as uint. As pthread_key_t is used as an opaque type and storage size of both int and uint are the same, this is rather a cosmetic change. iOS uses ulong (as OS X) so difference is critical on 64bit platforms.
2015-01-07std: prevent `CreateProcess()` race on Windowsklutzy-0/+7
Believe or not, `CreateProcess()` is racy if several threads create child processes: [0], [1], [2]. This caused some tests show crash dialogs during `make check-stage#-rpass`. More explanation: On Windows, `SetErrorMode()` controls display of error dialogs: it accepts new error mode and returns old error mode. The error mode is process-global and automatically inherited to child process when created. MSYS2 bash shell internally sets it to not show error dialogs, therefore `make check-stage#-rpass` should not show them either. However, [1] says that `CreateProcess()` internally invokes `SetErrorMode()` twice: at first it sets mode `0x8001` and saves original mode, and at second it restores original mode. So if two threads simultaneously call `CreateProcess()`, the first thread sets error mode to `0x8001` then the second thread recognizes that current error mode is `0x8001`. Therefore, The second thread will create process with wrong error mode. This really occurs inside `compiletest`: it creates several processes on each thread, so some `run-pass` tests are invoked with wrong error mode therefore show crash dialog. This commit adds `StaticMutex` for `CreateProcess()` call. This seems to fix the "dialog annoyance" issue.

2015-01-05std: Redesign c_str and c_vecAlex Crichton-116/+113
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
2015-01-03Remove deprecated functionalityAlex Crichton-43/+46
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.

2015-01-03auto merge of #20154 : P1start/rust/qualified-assoc-type-generics, ↵bors-4/+4
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.

2015-01-02std: Stabilize the prelude moduleAlex Crichton-66/+77
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.

2015-01-01std: Second pass stabilization of syncAlex Crichton-12/+8
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.

2014-12-31std: Second pass stabilization for thread_localAlex Crichton-2/+3
This commit performs a second pass over the `std::thread_local` module. Most of the functionality remains explicitly unstable, but the specific actions taken were: * `thread_local` is now stable * `thread_local!` is now stable * `thread_local::Key` is now stable * `thread_local::Key::with` is now stable * `thread_local::Key::destroyed` is deprecated in favor of a more general `state` function * `thread_local::Key::state` was added to query the three states that a key can be in: uninitialized, valid, or destroyed. This function, and the corresponding `State` enum, are both marked unstable as we may wish to expand it later on. * `thread_local::scoped` is entirely unstable. There hasn't been a whole lot of usage of this module in the standard distribution, so it remains unstable at this time. Note that while the structure `Key` is marked stable, it is currently forced to expose all of its implementation details due to the use of construction-via-macro. The use of construction-via-macro is currently required in order to place the `#[thread_local]` attribute on static in a platform-specific manner. These stability attributes were assigned assuming that it will be acceptable to tweak the implementation of `Key` in the future.

The new semantics of this function are that the callbacks are run when the *main thread* exits, not when all threads have exited. This implies that other threads may still be running when the `at_exit` callbacks are invoked and users need to be prepared for this situation. Users in the standard library have been audited in accordance to these new rules as well. Closes #20012

I've created a patch for #20226, which maps `EEXIST` to the `PathAlreadyExists` error on Unix. To test this, I use `mkdir`, which raises `EEXIST` if the directory already exists. On Windows, I map `ERROR_ALREADY_EXISTS` to `PathAlreadyExist`, but I am note sure if `mkdir` on Windows raises `ERROR_ALREADY_EXISTS` and do not have a Windows installation handy for testing. And I noticed another thing. No error seems to map to `IoErrorKind::PathDoesntExist` and I am wondering what the difference to `FileNotFound` is?

The reference/lifetime semantics as written are also problematic in how they encourage arbitrary lifetimes. * `zero_memory` - This function is currently not used at all in the distribution, and in general it plays a broader role in the "working with unsafe pointers" story. This story is not yet fully developed, so at this time the function remains unstable for now. * `read_and_zero` - This function remains unstable for largely the same reasons as `zero_memory`. * These functions are now all deprecated: * `PtrExt::null` - call `ptr::null` or `ptr::null_mut` instead. * `PtrExt::to_uint` - use an `as` expression instead.

2014-12-29std: Second pass stabilization for `comm`Alex Crichton-15/+15
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]
2014-12-29std: Return Result from RWLock/Mutex methodsAlex Crichton-5/+5
All of the current std::sync primitives have poisoning enable which means that when a task fails inside of a write-access lock then all future attempts to acquire the lock will fail. This strategy ensures that stale data whose invariants are possibly not upheld are never viewed by other tasks to help propagate unexpected panics (bugs in a program) among tasks. Currently there is no way to test whether a mutex or rwlock is poisoned. One method would be to duplicate all the methods with a sister foo_catch function, for example. This pattern is, however, against our [error guidelines][errors]. As a result, this commit exposes the fact that a task has failed internally through the return value of a `Result`. [errors]: https://github.com/rust-lang/rfcs/blob/master/text/0236-error-conventions.md#do-not-provide-both-result-and-fail-variants All methods now return a `LockResult<T>` or a `TryLockResult<T>` which communicates whether the lock was poisoned or not. In a `LockResult`, both the `Ok` and `Err` variants contains the `MutexGuard<T>` that is being returned in order to allow access to the data if poisoning is not desired. This also means that the lock is *always* held upon returning from `.lock()`. A new type, `PoisonError`, was added with one method `into_guard` which can consume the assertion that a lock is poisoned to gain access to the underlying data. This is a breaking change because the signatures of these methods have changed, often incompatible ways. One major difference is that the `wait` methods on a condition variable now consume the guard and return it in as a `LockResult` to indicate whether the lock was poisoned while waiting. Most code can be updated by calling `.unwrap()` on the return value of `.lock()`. [breaking-change]
