2020-04-06unistd: avoid infinite loop caused by reserve_double_buffer_sizeSteven Danna
Functions such as Group::from_anything use reserve_double_buffer_size in a loop, expecting it to return ERANGE if the passed limit is reached. However, the returned vector is passed as pointer to a libc function that writes data into memory and doesn't update the length of the Vec. Because of this, the previous code would never return ERANGE and the calling loops would never exit if they hit a case where the required buffer was larger than the maximum buffer. This fixes the problem by checking the capacity rather than the length. Signed-off-by: Steven Danna <steve@chef.io>

2020-01-12Add CLK_TCK to SysconfVarCaleb Bassi
http://man7.org/linux/man-pages/man3/sysconf.3.html says that the corresponding variable is obsolete, but I think that just means the constant defined in limits.h is obsolete. Checking the value using sysconf is still valid.

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

2019-01-15Fix 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.

2018-11-28Prefer `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.

`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`.
