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

2021-02-15Dir: Implement `IntoIterator` for `Dir`William Manley
This is useful to allow returning an iterator based on a directory iterator without needing a self-referential struct.
2021-02-07Don't implement Clone on Dir, SignalFd, and PtyMasterAlan Somers
Since they close their file descriptors on Drop, it's almost impossible to use Clone without creating a double-close situation. Also, check for EBADF in SignalFd::drop and Dir::drop.

2020-05-17Simply disable the dir module, since only the entry struct is availableXavier L'Heureux
2020-05-17Remove more unsupported functions and make it possible to run testsXavier L'Heureux
2020-05-17Add Redox support for most of the modulesXavier L'Heureux
Some things are not implemented yet in redox, so a lot of annotations were added to remove functions when compiling for redox. Those functions will hopefully be added in time, but for now it's better to have partial support than none. Blocked by https://github.com/rust-lang/libc/pull/1438
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

2019-06-11Use 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
2019-06-09Add extra traits for all typesBryant Mairs
Derive Clone, Copy, Eq, Hash, and PartialEq for all types. Not all traits are supported by all types, which is why many are missing some.
2018-09-03new dir moduleScott Lamb
This is a lower-level interface than `std::fs::ReadDir`. Notable differences: * can be opened from a file descriptor (as returned by `openat`, perhaps before knowing if the path represents a file or directory). Uses `fdopendir` for this, available on all Unix platforms as of rust-lang/libc#1018. * implements `AsRawFd`, so it can be passed to `fstat`, `openat`, etc. * can be iterated through multiple times without closing and reopening the file descriptor. Each iteration rewinds when finished. * returns entries for `.` (current directory) and `..` (parent directory). * returns entries' names as a `CStr` (no allocation or conversion beyond whatever libc does).
