2016-04-11std: Stabilize APIs for the 1.9 releaseAlex Crichton-3/+3
This commit applies all stabilizations, renamings, and deprecations that the library team has decided on for the upcoming 1.9 release. All tracking issues have gone through a cycle-long "final comment period" and the specific APIs stabilized/deprecated are: Stable * `std::panic` * `std::panic::catch_unwind` (renamed from `recover`) * `std::panic::resume_unwind` (renamed from `propagate`) * `std::panic::AssertUnwindSafe` (renamed from `AssertRecoverSafe`) * `std::panic::UnwindSafe` (renamed from `RecoverSafe`) * `str::is_char_boundary` * `<*const T>::as_ref` * `<*mut T>::as_ref` * `<*mut T>::as_mut` * `AsciiExt::make_ascii_uppercase` * `AsciiExt::make_ascii_lowercase` * `char::decode_utf16` * `char::DecodeUtf16` * `char::DecodeUtf16Error` * `char::DecodeUtf16Error::unpaired_surrogate` * `BTreeSet::take` * `BTreeSet::replace` * `BTreeSet::get` * `HashSet::take` * `HashSet::replace` * `HashSet::get` * `OsString::with_capacity` * `OsString::clear` * `OsString::capacity` * `OsString::reserve` * `OsString::reserve_exact` * `OsStr::is_empty` * `OsStr::len` * `std::os::unix::thread` * `RawPthread` * `JoinHandleExt` * `JoinHandleExt::as_pthread_t` * `JoinHandleExt::into_pthread_t` * `HashSet::hasher` * `HashMap::hasher` * `CommandExt::exec` * `File::try_clone` * `SocketAddr::set_ip` * `SocketAddr::set_port` * `SocketAddrV4::set_ip` * `SocketAddrV4::set_port` * `SocketAddrV6::set_ip` * `SocketAddrV6::set_port` * `SocketAddrV6::set_flowinfo` * `SocketAddrV6::set_scope_id` * `<[T]>::copy_from_slice` * `ptr::read_volatile` * `ptr::write_volatile` * The `#[deprecated]` attribute * `OpenOptions::create_new` Deprecated * `std::raw::Slice` - use raw parts of `slice` module instead * `std::raw::Repr` - use raw parts of `slice` module instead * `str::char_range_at` - use slicing plus `chars()` plus `len_utf8` * `str::char_range_at_reverse` - use slicing plus `chars().rev()` plus `len_utf8` * `str::char_at` - use slicing plus `chars()` * `str::char_at_reverse` - use slicing plus `chars().rev()` * `str::slice_shift_char` - use `chars()` plus `Chars::as_str` * `CommandExt::session_leader` - use `before_exec` instead.

2016-03-28Rollup merge of #32507 - klingtnet:master, r=steveklabnikSteve Klabnik-2/+7
Fix missing console output in `Barrier` example The `println!` calls in the previous version were never shown (at least not in the playpen) because the main thread is finished before all the spawned child threads were synchronized. This commit adds a join for each thread handle to wait in the main thread until all child threads are finished. r? @steveklabnik
2016-03-26std: Rewrite Once with poisoningAlex Crichton-56/+363
This commit rewrites the `std::sync::Once` primitive with poisoning in mind in light of #31688. Currently a panic in the initialization closure will cause future initialization closures to run, but the purpose of a Once is usually to initialize some global state so it's highly likely that the global state is corrupt if a panic happened. The same strategy of a mutex is taken where a panic is propagated by default. A new API, `call_once_force`, was added to subvert panics like is available on Mutex as well (for when panicking is handled internally). Adding this support was a significant enough change to the implementation that it was just completely rewritten from scratch, primarily to avoid using a `StaticMutex` which needs to have `destroy()` called on it at some point (a pain to do). Closes #31688

2016-03-12std: Clean out deprecated APIsAlex Crichton-279/+4
Removes all unstable and deprecated APIs prior to the 1.8 release. All APIs that are deprecated in the 1.8 release are sticking around for the rest of this cycle. Some notable changes are: * The `dynamic_lib` module was moved into `rustc_back` as the compiler still relies on a few bits and pieces. * The `DebugTuple` formatter now special-cases an empty struct name with only one field to append a trailing comma.

2016-03-01Explicitly opt out of `Sync` for `cell` and `mpsc` typesAndrew Paseltiner-0/+6
These types were already `!Sync`, but this improves error messages when they are used in contexts that require `Sync`, aligning them with conventions used with `Rc`, among others.
2016-02-29std: Stabilize APIs for the 1.8 releaseAlex Crichton-0/+11
This commit is the result of the FCPs ending for the 1.8 release cycle for both the libs and the lang suteams. The full list of changes are: Stabilized * `braced_empty_structs` * `augmented_assignments` * `str::encode_utf16` - renamed from `utf16_units` * `str::EncodeUtf16` - renamed from `Utf16Units` * `Ref::map` * `RefMut::map` * `ptr::drop_in_place` * `time::Instant` * `time::SystemTime` * `{Instant,SystemTime}::now` * `{Instant,SystemTime}::duration_since` - renamed from `duration_from_earlier` * `{Instant,SystemTime}::elapsed` * Various `Add`/`Sub` impls for `Time` and `SystemTime` * `SystemTimeError` * `SystemTimeError::duration` * Various impls for `SystemTimeError` * `UNIX_EPOCH` * `ops::{Add,Sub,Mul,Div,Rem,BitAnd,BitOr,BitXor,Shl,Shr}Assign` Deprecated * Scoped TLS (the `scoped_thread_local!` macro) * `Ref::filter_map` * `RefMut::filter_map` * `RwLockReadGuard::map` * `RwLockWriteGuard::map` * `Condvar::wait_timeout_with` Closes #27714 Closes #27715 Closes #27746 Closes #27748 Closes #27908 Closes #29866

2016-02-18Remove unnecessary explicit lifetime bounds.Corey Farwell-2/+2
These explicit lifetimes can be ommitted because of lifetime elision rules. Instances were found using rust-clippy.
2016-02-08std: `_lock` -> `_guard` in Mutex exampleBenjamin Herr-1/+1
The comment in the next line was already talking about `_guard`, and the scope guard a couple lines further down is also called `guard`, so I assume that was just a typo.
2016-02-07Auto merge of #31440 - reem:rwlock-map-fix, r=alexcrichtonbors-4/+6
Also update the instability reason to include a note about a possible bad interaction with condition variables on systems that allow waiting on a RwLock guard.
2016-02-06Auto merge of #31428 - reem:remove-mutexguard-map, r=alexcrichtonbors-60/+1
It could return in the future if it returned a different guard type, which could not be used with Condvar, otherwise it is unsafe as another thread can invalidate an "inner" reference during a Condvar::wait. cc #27746

2016-02-05Remove MutexGuard::map, as it is not safe in combination with Condvar.Jonathan Reem-60/+1
It could return in the future if it returned a different guard type, which could not be used with Condvar, otherwise it is unsafe as another thread can invalidate an "inner" reference during a Condvar::wait. cc #27746
2016-02-05Remove an unnecessary 'static bound in the impl of Debug for Mutex.Jonathan Reem-1/+1
There is no reason to require T: 'static; the bound appears to be a historical artifact.
2016-02-03Auto merge of #30834 - reem:rwlock-read-guard-map, r=alexcrichtonbors-57/+228
This is very useful when the RwLock 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.

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-5/+139
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-4/+4
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

2015-11-19std: Add Instant and SystemTime to std::timeAlex Crichton-5/+3
This commit is an implementation of [RFC 1288][rfc] which adds two new unstable types to the `std::time` module. The `Instant` type is used to represent measurements of a monotonically increasing clock suitable for measuring time withing a process for operations such as benchmarks or just the elapsed time to do something. An `Instant` favors panicking when bugs are found as the bugs are programmer errors rather than typical errors that can be encountered. [rfc]: https://github.com/rust-lang/rfcs/pull/1288 The `SystemTime` type is used to represent a system timestamp and is not monotonic. Very few guarantees are provided about this measurement of the system clock, but a fixed point in time (`UNIX_EPOCH`) is provided to learn about the relative distance from this point for any particular time stamp. This PR takes the same implementation strategy as the `time` crate on crates.io, namely: | Platform | Instant | SystemTime | |------------|--------------------------|--------------------------| | Windows | QueryPerformanceCounter | GetSystemTimeAsFileTime | | OSX | mach_absolute_time | gettimeofday | | Unix | CLOCK_MONOTONIC | CLOCK_REALTIME | These implementations can perhaps be refined over time, but they currently satisfy the requirements of the `Instant` and `SystemTime` types while also being portable across implementations and revisions of each platform.

This commit stabilizes and deprecates library APIs whose FCP has closed in the last cycle, specifically: Stabilized APIs: * `fs::canonicalize` * `Path::{metadata, symlink_metadata, canonicalize, read_link, read_dir, exists, is_file, is_dir}` - all moved to inherent methods from the `PathExt` trait. * `Formatter::fill` * `Formatter::width` * `Formatter::precision` * `Formatter::sign_plus` * `Formatter::sign_minus` * `Formatter::alternate` * `Formatter::sign_aware_zero_pad` * `string::ParseError` * `Utf8Error::valid_up_to` * `Iterator::{cmp, partial_cmp, eq, ne, lt, le, gt, ge}` * `<[T]>::split_{first,last}{,_mut}` * `Condvar::wait_timeout` - note that `wait_timeout_ms` is not yet deprecated but will be once 1.5 is released. * `str::{R,}MatchIndices` * `str::{r,}match_indices` * `char::from_u32_unchecked` * `VecDeque::insert` * `VecDeque::shrink_to_fit` * `VecDeque::as_slices` * `VecDeque::as_mut_slices` * `VecDeque::swap_remove_front` - (renamed from `swap_front_remove`) * `VecDeque::swap_remove_back` - (renamed from `swap_back_remove`) * `Vec::resize` * `str::slice_mut_unchecked` * `FileTypeExt` * `FileTypeExt::{is_block_device, is_char_device, is_fifo, is_socket}` * `BinaryHeap::from` - `from_vec` deprecated in favor of this * `BinaryHeap::into_vec` - plus a `Into` impl * `BinaryHeap::into_sorted_vec` Deprecated APIs * `slice::ref_slice` * `slice::mut_ref_slice` * `iter::{range_inclusive, RangeInclusive}` * `std::dynamic_lib` Closes #27706 Closes #27725 cc #27726 (align not stabilized yet) Closes #27734 Closes #27737 Closes #27742 Closes #27743 Closes #27772 Closes #27774 Closes #27777 Closes #27781 cc #27788 (a few remaining methods though) Closes #27790 Closes #27793 Closes #27796 Closes #27810 cc #28147 (not all parts stabilized)
2015-10-16Add `Shared` pointer and have `{Arc, Rc}` use itAndrew Paseltiner-0/+2
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.
