2017-12-19Add Hash impl for SystemTime and InstantVitaly _Vi Shukela-4/+12
Closes #46670.
2017-10-20Fix some tests for linux gnux32Marco A L Barbosa-2/+2
2017-09-07Properly detect overflow in Instance +/- Duration.kennytm-7/+15
Avoid unchecked cast from `u64` to `i64`. Use `try_into()` for checked cast. (On Unix, cast to `time_t` instead of `i64`.)
2017-04-25Fix a copy-paste error in `Instant::sub_duration`Tobias Bucher-1/+1
Fixes #41514.
2016-07-12Use `ptr::{null, null_mut}` instead of `0 as *{const, mut}`Tobias Bucher-2/+4
2016-05-24std: Stabilize APIs for the 1.10 releaseAlex Crichton-188/+130
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
2016-04-07Fix libstd on DragonFlyMichael Neumann-1/+6
Following changes: * birthtime does not exist on DragonFly * errno: __dfly_error is no more. Use #[thread_local] static errno. * clock_gettime expects a c_ulong (use a type alias) These changes are required to build DragonFly snapshots again.
2016-03-15std: Fix overflow when subtracting InstantAlex Crichton-4/+4
This code was currently only exercised on OSX, but this applies the same method of subtraction used on Linux which doesn't have the same overflow issues. Note that this currently includes no tests, but that's because this is only visible with debug assertions enabled. Soon, however, I'll enable debug assertions on all auto builds on the bots so we should get testing for this. Closes #32268
2016-02-04std: Expose SystemTime accessors on fs::MetadataAlex Crichton-0/+12
These accessors are used to get at the last modification, last access, and creation time of the underlying file. Currently not all platforms provide the creation time, so that currently returns `Option`.
2015-12-04Fix the time overflow on mac as wellSean Griffin-1/+1
2015-12-02Ensure two `SystemTime`s are equal when nanos add to exactly 1BSean Griffin-1/+1
Currently if you add a duration which should lead to 0 nanos and 1 additional second, we end up with no additional seconds, and 1000000000 nanos.
2015-11-19std: Add Instant and SystemTime to std::timeAlex Crichton-55/+326
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.

2015-11-09std: Migrate to the new libcAlex Crichton-13/+4
* Delete `sys::unix::{c, sync}` as these are now all folded into libc itself * Update all references to use `libc` as a result. * Update all references to the new flat namespace. * Moves all windows bindings into sys::c

2015-05-13std: Redesign Duration, implementing RFC 1040Alex Crichton-18/+12
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
2015-04-27std: Prepare for linking to muslAlex Crichton-1/+2
This commit modifies the standard library and its dependencies to link correctly when built against MUSL. This primarily ensures that the right libraries are linked against and when they're linked against they're linked against statically.
2015-03-12std: Remove #[allow] directives in sys modulesAlex Crichton-5/+3
These were suppressing lots of interesting warnings! Turns out there was also quite a bit of dead code.

2015-01-16Rewrite Condvar::wait_timeout and make it publicSteven Fackler-0/+124
**The implementation is a direct adaptation of libcxx's condition_variable implementation.** pthread_cond_timedwait uses the non-monotonic system clock. It's possible to change the clock to a monotonic via pthread_cond_attr, but this is incompatible with static initialization. To deal with this, we calculate the timeout using the system clock, and maintain a separate record of the start and end times with a monotonic clock to be used for calculation of the return value.
