2016-05-17std: Update libc submoduleAlex Crichton-0/+0
Brings in a fix where `-lutil` is no longer passed for musl targets, lifting the need for a musl toolchain to be installed again. Closes #33608

2016-04-04std: Fix linking against `signal` on AndroidAlex Crichton-0/+0
Currently the minimum supported Android version of the standard library is API level 18 (android-18). Back in those days [1] the `signal` function was just an inline wrapper around `bsd_signal`, but starting in API level android-20 the `signal` symbols was introduced [2]. Finally, in android-21 the API `bsd_signal` was removed [3]. Basically this means that if we want to be binary compatible with multiple Android releases (oldest being 18 and newest being 21) then we need to check for both symbols and not actually link against either. This was first discovered in rust-lang/libc#236 with a fix proposed in rust-lang/libc#237. I suspect that we'll want to accept rust-lang/libc#237 so Rust crates at large continue to be compatible with newer releases of Android and crates, like the standard library, that want to opt into older support can continue to do so via similar means. Closes rust-lang/libc#236 [1]: https://chromium.googlesource.com/android_tools/+/20ee6d20/ndk/platforms/android-18/arch-arm/usr/include/signal.h [2]: https://chromium.googlesource.com/android_tools/+/fbd420/ndk_experimental/platforms/android-20/arch-arm/usr/include/signal.h [3]: https://chromium.googlesource.com/android_tools/+/20ee6d/ndk/platforms/android-21/arch-arm/usr/include/signal.h
2016-03-09std: Don't spawn threads in `wait_with_output`Alex Crichton-0/+0
Semantically there's actually no reason for us to spawn threads as part of the call to `wait_with_output`, and that's generally an incredibly heavyweight operation for just reading a few bytes (especially when stderr probably rarely has bytes!). An equivalent operation in terms of what's implemented today would be to just drain both pipes of all contents and then call `wait` on the child process itself. On Unix we can implement this through some convenient use of the `select` function, whereas on Windows we can make use of overlapped I/O. Note that on Windows this requires us to use named pipes instead of anonymous pipes, but they're semantically the same under the hood.

2016-02-21std: Use Android LFS off64_t, ftruncate64, and lseek64Josh Stone-0/+0
Android should use 64-bit LFS symbols for `lseek` and `ftruncate`, lest those offset parameters suffer a lossy cast down to a 32-bit `off_t`. Unlike GNU/Linux, Android's `stat`, `dirent`, and related functions are always 64-bit LFS compatible, and `open` already implies `O_LARGEFILE`, so all those don't need to follow Linux. It might be nice to unify them anyway, but those other LFS symbols aren't present in API 18 bionic. r? @alexcrichton
2016-02-18Remove alternate stack with sigaltstack before unmapping it.Tomasz Miąsko-0/+0
Also reuse existing signal stack if already set, this is especially useful when working with sanitizers that configure alternate stack themselves.
2016-02-05std: Add a helper for symbols that may not existAlex Crichton-0/+0
Right now we only attempt to call one symbol which my not exist everywhere, __pthread_get_minstack, but this pattern will come up more often as we start to bind newer functionality of systems like Linux. Take a similar strategy as the Windows implementation where we use `dlopen` to lookup whether a symbol exists or not.

2016-01-29add support for mips(el)-unknown-linux-muslJorge Aparicio-0/+0
This target covers MIPS devices that run the trunk version of OpenWRT. The x86_64-unknown-linux-musl target always links statically to C libraries. For the mips(el)-unknown-linux-musl target, we opt for dynamic linking (like most of other targets do) to keep binary size down. As for the C compiler flags used in the build system, we use the same flags used for the mips(el)-unknown-linux-gnu target.

2015-09-26Add support for the rumprun unikernelSebastian Wicki-1/+5
For most parts, rumprun currently looks like NetBSD, as they share the same libc and drivers. However, being a unikernel, rumprun does not support process management, signals or virtual memory, so related functions might fail at runtime. Stack guards are disabled exactly for this reason. Code for rumprun is always cross-compiled, it uses always static linking and needs a custom linker.

separate use code between openbsd/netbsd. netbsd use c_int and c_uint, but openbsd not, resulting a unused_import error.

2015-08-30Atomically set CLOEXEC on duplicated socketsTobias Bucher-1/+6
For Bitrig, NetBSD and OpenBSD the constant was incorrectly in posix01, when it's actually posix08, so we move it. This is a [breaking-change], but we already had one in #27930. Fix NetBSD's F_DUPFD_CLOEXEC constant. For a similar feature detection, see this musl thread: http://comments.gmane.org/gmane.linux.lib.musl.general/2963 This assumes that an int literal has type `c_int` for varidic functions.
2015-08-28libc: Fix constants used by `libc::pathconf`Barosl Lee-2/+17
`_PC_NAME_MAX` is necessary to use `libc::pathconf`. Its value is fixed to 3 currently, but actually it varies with the platform. * _PC_NAME_MAX == 3 Linux (glibc): https://sourceware.org/git/?p=glibc.git;a=blob;f=bits/confname.h;h=1c714dfbf9398b8a600f9b69426a7ad8c7e89ab4;hb=HEAD#l32 NaCl (newlib): https://chromium.googlesource.com/native_client/nacl-newlib/+/373135ec5241d09138aa56603742b94b3b64ea1d/newlib/libc/include/sys/unistd.h#430 * _PC_NAME_MAX == 4 Android (Bionic): https://github.com/android/platform_bionic/blob/7e919daeaad62515ebbbf7b06badc77625a14d90/libc/include/unistd.h#L59 FreeBSD: https://svnweb.freebsd.org/base/head/sys/sys/unistd.h?revision=239347&view=markup#l127 NetBSD: http://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/sys/sys/unistd.h OS X: http://opensource.apple.com/source/xnu/xnu-2782.10.72/bsd/sys/unistd.h This commit fixes this, and also addes the `_PC_PATH_MAX` constant needed by further commits.

2015-08-12libc: Fix backcompat with crates.io versionAlex Crichton-1/+12
The corrected signature of `ioctl` broke some crates on crates.io, and it's not currently worth the major version bump of libc, so for now keep the old signature around for crates.io builds only with a comment to remove it at a future date. This should allow libc on crates.io to update to the master version in-tree. I've verified that this was the only breakage of substance between the version libc is currently built with and today's master branch.

2015-08-03syntax: Implement #![no_core]Alex Crichton-2/+3
This commit is an implementation of [RFC 1184][rfc] which tweaks the behavior of the `#![no_std]` attribute and adds a new `#![no_core]` attribute. The `#![no_std]` attribute now injects `extern crate core` at the top of the crate as well as the libcore prelude into all modules (in the same manner as the standard library's prelude). The `#![no_core]` attribute disables both std and core injection. [rfc]: https://github.com/rust-lang/rfcs/pull/1184
