2016-01-16std: Stabilize APIs for the 1.7 releaseAlex Crichton-0/+19
This commit stabilizes and deprecates the FCP (final comment period) APIs for the upcoming 1.7 beta release. The specific APIs which changed were: Stabilized * `Path::strip_prefix` (renamed from `relative_from`) * `path::StripPrefixError` (new error type returned from `strip_prefix`) * `Ipv4Addr::is_loopback` * `Ipv4Addr::is_private` * `Ipv4Addr::is_link_local` * `Ipv4Addr::is_multicast` * `Ipv4Addr::is_broadcast` * `Ipv4Addr::is_documentation` * `Ipv6Addr::is_unspecified` * `Ipv6Addr::is_loopback` * `Ipv6Addr::is_unique_local` * `Ipv6Addr::is_multicast` * `Vec::as_slice` * `Vec::as_mut_slice` * `String::as_str` * `String::as_mut_str` * `<[T]>::clone_from_slice` - the `usize` return value is removed * `<[T]>::sort_by_key` * `i32::checked_rem` (and other signed types) * `i32::checked_neg` (and other signed types) * `i32::checked_shl` (and other signed types) * `i32::checked_shr` (and other signed types) * `i32::saturating_mul` (and other signed types) * `i32::overflowing_add` (and other signed types) * `i32::overflowing_sub` (and other signed types) * `i32::overflowing_mul` (and other signed types) * `i32::overflowing_div` (and other signed types) * `i32::overflowing_rem` (and other signed types) * `i32::overflowing_neg` (and other signed types) * `i32::overflowing_shl` (and other signed types) * `i32::overflowing_shr` (and other signed types) * `u32::checked_rem` (and other unsigned types) * `u32::checked_neg` (and other unsigned types) * `u32::checked_shl` (and other unsigned types) * `u32::saturating_mul` (and other unsigned types) * `u32::overflowing_add` (and other unsigned types) * `u32::overflowing_sub` (and other unsigned types) * `u32::overflowing_mul` (and other unsigned types) * `u32::overflowing_div` (and other unsigned types) * `u32::overflowing_rem` (and other unsigned types) * `u32::overflowing_neg` (and other unsigned types) * `u32::overflowing_shl` (and other unsigned types) * `u32::overflowing_shr` (and other unsigned types) * `ffi::IntoStringError` * `CString::into_string` * `CString::into_bytes` * `CString::into_bytes_with_nul` * `From<CString> for Vec<u8>` * `From<CString> for Vec<u8>` * `IntoStringError::into_cstring` * `IntoStringError::utf8_error` * `Error for IntoStringError` Deprecated * `Path::relative_from` - renamed to `strip_prefix` * `Path::prefix` - use `components().next()` instead * `os::unix::fs` constants - moved to the `libc` crate * `fmt::{radix, Radix, RadixFmt}` - not used enough to stabilize * `IntoCow` - conflicts with `Into` and may come back later * `i32::{BITS, BYTES}` (and other integers) - not pulling their weight * `DebugTuple::formatter` - will be removed * `sync::Semaphore` - not used enough and confused with system semaphores Closes #23284 cc #27709 (still lots more methods though) Closes #27712 Closes #27722 Closes #27728 Closes #27735 Closes #27729 Closes #27755 Closes #27782 Closes #27798

This adds the ability to override the default OOM behavior by setting a handler function. This is used by libstd to print a message when running out of memory instead of crashing with an obscure "illegal hardware instruction" error (at least on Linux). Fixes #14674

2016-01-12make siginfo_si_addr() returns a usizeSébastien Marie-5/+5
`siginfo_si_addr()` function is used once, and the returned value is casted to `usize`. So make the function returns a `usize`. it simplifies OpenBSD case, where the return type wouldn't be a `*mut libc::c_void` but a `*mut libc::c_char`.

It returns sizeof(dirent_t), so I'm not sure why its return type is int. It's only used once, and that usage immediately casts it to usize.

2015-11-19Auto merge of #29894 - alexcrichton:stdtime, r=brsonbors-94/+506
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. cc #29866

Otherwise, the iterator and the functions for getting specific environment variables might disagree, for environments like FOOBAR Variable names starting with equals sign are OK: glibc only interprets equals signs not in the first position as separators between variable name and variable value. Instead of skipping them entirely, a leading equals sign is interpreted to be part of the variable name.

* Store the native representation directly in the `ExitStatus` structure instead of a "parsed version" (mostly for Unix). * On Windows, be more robust against processes exiting with the status of 259. Unfortunately this exit code corresponds to `STILL_ACTIVE`, causing libstd to think the process was still alive, causing an infinite loop. Instead the loop is removed altogether and `WaitForSingleObject` is used to wait for the process to exit.

2015-11-06Auto merge of #29305 - alexcrichton:bad-getenv, r=brsonbors-46/+52
As discovered in #29298, `env::set_var("", "")` will panic, but it turns out that it *also* deadlocks on Unix systems. This happens because if a panic happens while holding the environment lock, we then go try to read RUST_BACKTRACE, grabbing the environment lock, causing a deadlock. Specifically, the changes made here are: * The environment lock is pushed into `std::sys` instead of `std::env`. This also only puts it in the Unix implementation, not Windows where the functions are already threadsafe. * The `std::sys` implementation now returns `io::Result` so panics are explicitly at the `std::env` level.
