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

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.

1035: Implement extra traits for all types r=asomers a=Susurrus Now that I've gotten all the extra traits implemented for `libc`, they can be easily derived for `nix`'s types. Note that this requires a bump to the minimum supported Rust version, but it's still at least 2 versions behind, so it fits in with policy. One thing I did notice is that we have an inconsistent approach to our newtypes, where some use a struct and some a tuple struct. We should be consistent here, and should probably use a tuple struct since the name of the single field is irrelevant. This style is already suggested in our `CONVENTIONS.md` doc, so this should be uncontroversial. I'll file a PR after this is merged adding that. Co-authored-by: Bryant Mairs <bryant@mai.rs>
2019-06-11Use ptr::NonNull for DirBryant Mairs
This is a minor optimization that allows for reduced sizes of datatypes. Since this pointer will never be NULL, it's safe to use here
2019-06-11Fix tests for abstract socketsBryant Mairs
Abstract paths should always be N-1 in length where N is the length of the `sun_path` field (first byte is \0). Given that, `UnixAddr::new_abstract()` should always return this N-1 length, not just the length of the string provided (the rest of the array will be \0s).

1.0.2 adds the ability to omit the else clause, a feature we use.
