2017-06-15Fix condvar.wait(distant future) return immediately on OSXStepan Koltsov-15/+51
Fixes issue #37440: `pthread_cond_timedwait` on macOS Sierra seems to overflow `ts_sec` parameter and returns immediately. To work around this problem patch rounds timeout down to approximately 1000 years. Patch also fixes overflow when converting `u64` to `time_t`.

Use monotonic time in condition variables. Configure condition variables to use monotonic time using pthread_condattr_setclock on systems where this is possible. This fixes the issue when thread waiting on condition variable is woken up too late when system time is moved backwards.

2016-07-12std: Clean out deprecated APIsAlex Crichton-296/+72
This primarily removes a lot of `sync::Static*` APIs and rejiggers the associated implementations. While doing this it was discovered that the `is_poisoned` method can actually result in a data race for the Mutex/RwLock primitives, so the inner `Cell<bool>` was changed to an `AtomicBool` to prevent the associated data race. Otherwise the usage/gurantees should be the same they were before.
2016-05-24std: Stabilize APIs for the 1.10 releaseAlex Crichton-0/+24
This commit applies the FCP decisions made by the libs team for the 1.10 cycle, including both new stabilizations and deprecations. Specifically, the list of APIs is: Stabilized: * `os::windows::fs::OpenOptionsExt::access_mode` * `os::windows::fs::OpenOptionsExt::share_mode` * `os::windows::fs::OpenOptionsExt::custom_flags` * `os::windows::fs::OpenOptionsExt::attributes` * `os::windows::fs::OpenOptionsExt::security_qos_flags` * `os::unix::fs::OpenOptionsExt::custom_flags` * `sync::Weak::new` * `Default for sync::Weak` * `panic::set_hook` * `panic::take_hook` * `panic::PanicInfo` * `panic::PanicInfo::payload` * `panic::PanicInfo::location` * `panic::Location` * `panic::Location::file` * `panic::Location::line` * `ffi::CStr::from_bytes_with_nul` * `ffi::CStr::from_bytes_with_nul_unchecked` * `ffi::FromBytesWithNulError` * `fs::Metadata::modified` * `fs::Metadata::accessed` * `fs::Metadata::created` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange` * `sync::atomic::Atomic{Usize,Isize,Bool,Ptr}::compare_exchange_weak` * `collections::{btree,hash}_map::{Occupied,Vacant,}Entry::key` * `os::unix::net::{UnixStream, UnixListener, UnixDatagram, SocketAddr}` * `SocketAddr::is_unnamed` * `SocketAddr::as_pathname` * `UnixStream::connect` * `UnixStream::pair` * `UnixStream::try_clone` * `UnixStream::local_addr` * `UnixStream::peer_addr` * `UnixStream::set_read_timeout` * `UnixStream::set_write_timeout` * `UnixStream::read_timeout` * `UnixStream::write_Timeout` * `UnixStream::set_nonblocking` * `UnixStream::take_error` * `UnixStream::shutdown` * Read/Write/RawFd impls for `UnixStream` * `UnixListener::bind` * `UnixListener::accept` * `UnixListener::try_clone` * `UnixListener::local_addr` * `UnixListener::set_nonblocking` * `UnixListener::take_error` * `UnixListener::incoming` * RawFd impls for `UnixListener` * `UnixDatagram::bind` * `UnixDatagram::unbound` * `UnixDatagram::pair` * `UnixDatagram::connect` * `UnixDatagram::try_clone` * `UnixDatagram::local_addr` * `UnixDatagram::peer_addr` * `UnixDatagram::recv_from` * `UnixDatagram::recv` * `UnixDatagram::send_to` * `UnixDatagram::send` * `UnixDatagram::set_read_timeout` * `UnixDatagram::set_write_timeout` * `UnixDatagram::read_timeout` * `UnixDatagram::write_timeout` * `UnixDatagram::set_nonblocking` * `UnixDatagram::take_error` * `UnixDatagram::shutdown` * RawFd impls for `UnixDatagram` * `{BTree,Hash}Map::values_mut` * `<[_]>::binary_search_by_key` Deprecated: * `StaticCondvar` - this, and all other static synchronization primitives below, are usable today through the lazy-static crate on stable Rust today. Additionally, we'd like the non-static versions to be directly usable in a static context one day, so they're unlikely to be the final forms of the APIs in any case. * `CONDVAR_INIT` * `StaticMutex` * `MUTEX_INIT` * `StaticRwLock` * `RWLOCK_INIT` * `iter::Peekable::is_empty` Closes #27717 Closes #27720 cc #27784 (but encode methods still exist) Closes #30014 Closes #30425 Closes #30449 Closes #31190 Closes #31399 Closes #31767 Closes #32111 Closes #32281 Closes #32312 Closes #32551 Closes #33018

2016-03-12std: Clean out deprecated APIsAlex Crichton-49/+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.
2016-02-29std: Stabilize APIs for the 1.8 releaseAlex Crichton-0/+3
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

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.

2015-10-25std: Stabilize library APIs for 1.5Alex Crichton-4/+3
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)

2015-08-19Make Condvar::wait_timeout return an enum instead of a boolSteven Fackler-18/+44
Returning a primitive bool results in a somewhat confusing API - does `true` indicate success - i.e. no timeout, or that a timeout has occurred? An explicitly named enum makes it clearer. [breaking-change]

2015-05-13std: Redesign Duration, implementing RFC 1040Alex Crichton-19/+63
This commit is an implementation of [RFC 1040][rfc] which is a redesign of the currently-unstable `Duration` type. The API of the type has been scaled back to be more conservative and it also no longer supports negative durations. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1040-duration-reform.md The inner `duration` module of the `time` module has now been hidden (as `Duration` is reexported) and the feature name for this type has changed from `std_misc` to `duration`. All APIs accepting durations have also been audited to take a more flavorful feature name instead of `std_misc`. Closes #24874
2015-04-21std: Remove deprecated/unstable num functionalityAlex Crichton-8/+0
This commit removes all the old casting/generic traits from `std::num` that are no longer in use by the standard library. This additionally removes the old `strconv` module which has not seen much use in quite a long time. All generic functionality has been supplanted with traits in the `num` crate and the `strconv` module is supplanted with the [rust-strconv crate][rust-strconv]. [rust-strconv]: https://github.com/lifthrasiir/rust-strconv This is a breaking change due to the removal of these deprecated crates, and the alternative crates are listed above. [breaking-change]

2015-04-08Implement reentrant mutexes and make stdio use themSimonas Kazlauskas-3/+3
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.
2015-04-01Stabilize basic timeout functionalityAaron Turon-19/+31
This commit renames and stabilizes: * `Condvar::wait_timeout_ms` (renamed from `wait_timeout`) * `thread::park_timeout_ms` (renamed from `park_timeout`) * `thread::sleep_ms` (renamed from `sleep`) In each case, the timeout is taken as a `u32` number of milliseconds, rather than a `Duration`. These functions are likely to be deprecated once a stable form of `Duration` is available, but there is little cost to having these named variants around, and it's crucial functionality for 1.0.
