2019-09-25unistd: getgroups: Rework variable namesOtavio Salvador
We are preparing the use of `reserve_double_buffer_size` but for this, some logic need to be reworked so we are doing some rename preparing for the next patch which adds its use. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>

2019-09-21unistd: getcwd: Double the buffer when need, up to PATH_MAX as limitOtavio Salvador
We now have a `reserve_double_buffer_size` method which reserves the double of buffer, up to a limit, allowing it to be reused on other methods in future. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>
2019-09-03Replace most instances of mem::uninitialized with mem::MaybeUninitAlan Somers
Only two instances remain: * For the deprecated sys::socket::CmsgSpace::new. We should probably just remove that method. * For sys::termios::Termios::default_uninit. This will require some more thought. Fixes #1096

2019-07-14Implement unlinkatJohnnie Birch
This adds the unlinkat function, which is part of POSIX: http://pubs.opengroup.org/onlinepubs/9699919799/functions/unlinkat.html and widely implmented on Unix-family platforms. Implement unlinkat - Update comments to unlink at and breakup tests Changes made based on comments from pull request #1058 Implement unlinkat - Update should_panic for more precise check Updae should_panic attribute for more precise check. Also remove some dead code and note the pull request ID. Implement unlinkat - Update error handling to use unwrap_err The previous patch failed testing on two targets that returned EPERM as the Sys error instead of EISDIR. This patch changes from using the should_panic attribute to using the unwrap_err and matching against the result. Implement Unlinkat - Passing tests should not print anything. Fix. Implement unlinkat - Update location of commit comment in the CHANGELOG Implement unlinkat - Remove newline

2019-03-03Fix the build on OSX with libc 0.2.49Alan Somers
Several symbols are now marked as deprecated on OSX. Fix the build by marking these symbols' Nix wrappers as deprecated, too.
2019-01-15Fix build and tests issues on OpenBSD 6.4+Andrei-Marius Radu
1) lutimes doesn't exist on OpenBSD so it needs to be under conditional compilation. The only "reference" that I could find related to this is the discussion here: https://github.com/rust-lang/libc/pull/790 . 2) fexecve doesn't exist on OpenBSD so add conditional compilation for it in unistd and in related tests. The only "reference" that I could find is a mention that fexecve is not implemented on OpenBSD in the manual pages for signal(3) and sigaction(2): Official repository (search for "fexecve"): https://cvsweb.openbsd.org/src/lib/libc/sys/sigaction.2?rev=1.75&content-type=text/x-cvsweb-markup Github mirror: https://github.com/openbsd/src/blob/master/lib/libc/sys/sigaction.2#L619 3) AIO doesn't work on OpenBSD so put test_aio_drop under conditional compilation. 4) Add relevant changelog entries. P.S. On OpenBSD remains the issue of test_scm_rights which builds correctly but fails at runtime.

2018-12-08Replace try! with ?Alan Somers
try! is not available in Rust 2018
2018-11-28Prefer `map(drop)` to `map(|_| ())`Alan Somers
I previously advocated for the latter syntax on stylistic grounds. But it generates less efficient code, because it creates a new lambda function for each usage. The optimizer does not combine them. This change saves about 6KB of code.

This also adds a test for truncate (obviously) but, while doing so, also adds a test for the already-existing ftruncate.

2018-01-11Remove return value from `pause`Thomas de Zeeuw
`pause` will always return `-1` as a result and sets `errno` to `EINTR`, which indicates that a signal was caught by the process. Since this is the point of `pause` return an error here makes little sense. Closes #827.

799: Fix nix on Dragonfly r=Susurrus a=mneumann This commit replaces pull request https://github.com/nix-rust/nix/pull/684. It fixes building `nix` on DragonFly. All tests pass. This requires most recent libc to build: https://github.com/rust-lang/libc/pull/851.
2017-12-19Fix support for DragonFlyMichael Neumann
* DragonFly does not have a O_DSYNC flag * Fix type_of_cmsg_data on DragonFly * No fexecve() on DragonFly * Do not run aio test cases on DragonFly * Keep target lists in alphabetical order * Unscrable #[cfg] directives and use cfg_if! macro instead * Fix errno on DragonFly Below follows an explanation why we have to use a C extension to get errno working on DragonFly: DragonFly uses a thread-local errno variable, but #[thread_local] is feature-gated and not available in stable Rust as of this writing (Rust 1.21.0). We have to use a C extension (src/errno_dragonfly.c) to access it. Tracking issue for `thread_local` stabilization: https://github.com/rust-lang/rust/issues/29594 Once this becomes stable, we can remove build.rs, src/errno_dragonfly.c, remove the build-dependency from Cargo.toml, and use: extern { #[thread_local] static errno: c_int; } Now all targets will use the build.rs script, but only on DragonFly this will do something. Also, there are no additional dependencies for targets other than DragonFly (no gcc dep).

2017-12-10Fix doctest that weren't run with the old doctest parserBryant Mairs
The switch to Pulldown for the Markdown parser for Rustdoc has revealed that there were a large number of doctests that weren't being run. These tests failed to compile before, but will also fail to run because they attach to arbitrary user and group IDs, which likely don't exist on the system. These are therefore marked as `no_run`.

777: Use the real pipe2(2) on most targets r=asomers a=asomers FreeBSD added pipe2(2) in version 10.0.
2017-12-07Use the real pipe2(2) on all BSD targets.Alan Somers
All supported non-Apple platforms now use the native syscall. Only ios and macos lack it. Deprecate pipe2 on those platforms, because it's impossible to guarantee atomicity with a userland implementation. It was added in: * DragonflyBSD 4.2 * FreeBSD 10.0 * NetBSD 6.0 * OpenBSD 5.7

cc #664 (unsure if this is everything needed)
2017-12-02Upgrade to Bitflags 1.0Bryant Mairs
The libc_bitflags! macro was replaced with a non-recursive one supporting only public structs. I could not figure out how to make the old macro work with the upgrade, so I reworked part of the bitflags! macro directly to suit our needs, much as the original recursive macro was made. There are no uses of this macro for non-public structs, so this is not a problem for internal code.
2017-11-19unistd: add execveat() on Linux and AndroidLuca Bruno
This adds execveat() to `nix::unistd`. It uses the execveat(2) Linux kernel syscall, which is available since 3.19. This is a Linux-specific extension which is not covered by POSIX and does not have any userland libc wrapper. Ref: http://man7.org/linux/man-pages/man2/execveat.2.html
