2019-09-19Require CAP_SYS_PTRACE for certain testsAlan Somers
process_vm_readv requires it, and I'm not exactly sure which other things do too.

1120: Fix length of abstract socket address r=asomers a=yshui NULL bytes have no special significance in an abstrace address, and the length of the address is solely decided by the length member. If the length is set to sun_path.len(), all the NULL bytes will be considered part of the address. Tests are updated accordingly.

1114: Replace most instances of mem::uninitialized with mem::MaybeUninit r=asomers a=asomers 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. Co-authored-by: Alan Somers <asomers@gmail.com>
2019-09-03Skip the aio_suspend test on LinuxAlan Somers
On Travis (and only on Travis) this test crashes. It hits an internal assertion within glibc. It happens reliably with rustc 1.37.0. Ignore the test until Travis updates its images; then we'll try again. Issue #1099
2019-09-03Workaround an outdated Travis imageAlan Somers
Travis's "stable" images are stuck on Rust 1.35.0

1109: fix readlink/readlinkat to return too long only when it is long r=asomers a=sendilkumarn Currently readlink returns `ENAMETOOLONG` when the bufferSize is equal to the result size. Consider the below case ```c++ int main(int argc, const char * argv[]) { std::string filename = "/tmp/test-dir/target"; size_t bufferSize = 9; char* buffer = new char[bufferSize]; size_t rc = readlink (filename.c_str(), buffer, bufferSize); // Since `readlink's` output depends on the `bufferSize`. If the`bufferSize` is 9 or greater than // 9 then it will return 9 or else it will return `bufferSize` as the value of `rc`. return 0; } ``` Co-authored-by: Sendil Kumar <sendilkumarn@live.com> Co-authored-by: Sendil Kumar N <sendilkumarn@live.com>

1097: Add renameat, AT_FDCWD r=asomers a=scottlamb Co-authored-by: Scott Lamb <slamb@slamb.org>
2019-07-17Add renameatScott Lamb
renameat is (somewhat oddly, imho) in stdio.h. I put it in nix::fcntl because there's no nix::stdio and all its friends (including the AT_* constants) are in nix::fcntl.

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

check is faster than build.
2019-07-13Fix warnings on Rust 1.37.0Alan Somers
* Replace obsolete range syntax "..." with inclusive range "..=" * Use dyn Trait syntax instead of Box<Trait> * Raise MSRV to 1.27.0 (for dyn Trait syntax) * Raise MSRV to 1.31.0 (because of rand) tempfile pulls in rand, and rand pulls in fuchsia-cprng, which requires 1.31.0. Why rand pulls in fuchsia-cprng I don't know. It's specified as a target-specific dependency, but Cargo tries to build it anyway (only on Linux, not on FreeBSD or OSX). A bug in Cargo 1.27.0?

1090: Expose sched_yield on non-linux-like hosts r=asomers a=kubkon Currently, `sched` module is compiled only for linux-like hosts. However, the recently added syscall `sched_yield` is universal to all *nixes. This PR pulls all linux-like functionality into a private `sched_linux_like` module which is enabled only for android and linux hosts, while `sched_yield` and `sched` modules are now compiled for all *nixes, thus, correctly exposing `sched_yield` to other non-linux hosts.
