1473: sys/stat: add a safe wrapper for mknodat(2) r=asomers a=lucab This introduces a new `mknodat` helper. Ref: https://pubs.opengroup.org/onlinepubs/9699919799/functions/mknod.html 1474: Mark most C-derived enums as non_exhaustive r=asomers a=asomers Since libc may add new variants at any time, Nix's consumers should not use exhaustive match patterns. Fixes #1182 1476: Constify many functions r=asomers a=asomers Constify most functions that can be constified. The exceptions are mostly accessors for structs that have no const constructor.

2021-07-07Collapse Error into ErrnoAlan Somers
Now that Nix's weird error types are eliminated, there's no reason not to simply use Errno as the Error type.
2021-07-07Overhaul Nix's error typesAlan Somers
For many of Nix's consumers it be convenient to easily convert a Nix error into a std::io::Error. That's currently not possible because of the InvalidPath, InvalidUtf8, and UnsupportedOperation types that have no equivalent in std::io::Error. However, very few of Nix's public APIs actually return those unusual errors. So a more useful API would be for Nix's standard error type to implement Into<std::io::Error>. This commit makes Error a simple NewType around Errno. For most functions it's a drop-in replacement. There are only three exceptions: * clearenv now returns a bespoke error type. It was the only Nix function whose error couldn't be cleanly mapped onto an Errno. * sys::signal::signal now returns Error(Errno::ENOTSUP) instead of Error::UnsupportedOperation when the user passes an incompatible argument to `handler`. * When a NixPath exceeds PATH_MAX, it will now return Error(Errno::ENAMETOOLONG) instead of Error::InvalidPath. In the latter two cases there is now some abiguity about whether the error code was generated by Nix or by the OS. But I think the ambiguity is worth it for the sake of being able to implement Into<io::Error>. This commit also introduces Error::Sys() as a migration aid. Previously that as an enum variant. Now it's a function, but it will work in many of the same contexts as the original. Fixes #1155

2020-07-07Adding an implementation and some basic tests for timerfd.Vincent Dagonneau
Removed support for timerfd on Android as it seems to have been deprecated? See https://android.googlesource.com/platform/development/+/73a5a3b/ndk/platforms/android-20/include/sys/timerfd.h or https://github.com/rust-lang/libc/issues/1589 Removed the public status of `TimerSpec`, as it should not be exposed to the user. Implemented `FromRawFd` for `TimerFd` as it already implements `AsRawFd`. Addressed comments from the latest code review: - Removed upper bound assertions on timer expirations in tests. - Made the main example runnable and added code to show how to wait for the timer. - Refactored `ClockId` to use `libc_enum`. - Added comments for all public parts of the module. - Wrapped to 80 cols. - Changed the size of the buffer in the tests to the minimum required. * Ran rustfmt. * Added a `From` implementation for `libc::timespec` -> `TimeSpec`. * Reworked the example with the new changes and changed the timer from 5 to 1 second. * Added a constructor for a 0-initialized `TimerSpec`. * Added a new method to get the timer configured expiration (based on timerfd_gettime). * Added an helper method to unset the expiration of the timer. * Added a `wait` method to actually read from the timer. * Renamed `settime` into just `set`. * Refactored the tests and added a new one that tests both the `unset` and the `get` method. Modified CHANGELOG.
