2021-12-30Introduce timer_* supportBrian L. Troutwine
This commit adds support for the signal timer mechanism in POSIX, the mirror to timerfd on Linux. Resolves #1424 Signed-off-by: Brian L. Troutwine <brian@troutwine.us>
2021-12-26Fix typosRyan Zoeller
2021-12-20feature-gate most Nix functionsVincent Dagonneau
Using features reduces build time and size for consumer crates. By default all features are enabled.
2021-11-26Update doc comment to match type `Option<Signal>`Johannes Schilling
This has previously been done for `killpg`, but not `kill` it seems.
2021-09-19Clippy cleanupAlan Somers
And this time, start running Clippy in CI
2021-09-04Remove SigevNotify on OpenBSD and RedoxAlan Somers
Because nothing uses it on those OSes.
2021-09-04Document more thingsAlan Somers
Also, test rustdoc in CI, and demote missing_docs from a deny to a warning (but still deny it in CI).
2021-08-28More rust docsAlan Somers
Switch from allow(missing_docs) to deny(missing_docs), which should gradually help us moving forward. Also, add a few missing docs, such as for sched and aio.
2021-08-13constify more functionsAlan Somers
Constify more functions, since we're raising the MSRV from 1.41.0 to 1.46.0. Fixes #1477

1484: Optionally implement TryFrom in libc_enum! r=asomers a=asomers This saves code in several separate places that need to do this separately. At the same time, remove a few uses of mem::transmute that were implementing TryFrom or similar functionality. Issue #373 Co-authored-by: Alan Somers <asomers@gmail.com>

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.

2021-07-07Overhaul 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
2021-05-30Suppress a build warning on FuchsiaAlan Somers
Beginning with 1.41.0, Rust considers it UB to zero-initialize a function pointer, even if you try to hide it behind `mem::MaybeUninit`. Suppress this warning to fix the build until we come up with a better permanent solution. Issue #1441

2020-05-17Fix test and remove group & user for redoxXavier L'Heureux
- Make sure all tests pass the CI - Redox does not (yet) have passwd functions, so remove it

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

2019-09-04Replace Signal::from_c_int by Signal::try_fromAlan Somers
TryFrom wasn't stable when that function was written.
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

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.

2019-03-03Fix test_thread_signal* test failures with Cargo 1.33.0Alan Somers
Previous versions of Cargo would create and destroy a new thread for each test. Cargo 1.33.0 instead creates a thread pool and reuses the same thread for multiple tests. Some Nix tests that changed the per-thread sigmask began to fail as a result, because they didn't do any cleanup. The easiest solution is to spawn a new thread for each of those tests.

884: impl FromStr for sys::Signal r=Susurrus a=quodlibetor This implements both ALLCAPS and lowercase full name (including SIG) and short name. This matches what `kill` accepts in many shells, and it also allows the `Debug` representation of `Signal`, which means it can be round-tripped, if desired. Co-authored-by: Brandon W Maister <quodlibetor@gmail.com>
2018-09-04impl FromStr and Display for sys::SignalBrandon W Maister
This is a subset of what `kill` accepts in many shells. The Display implementation matches the `Debug` representation of `Signal`. The `FromStr` matches both Debug/Display which means it can be round-tripped, if desired.
2018-05-05Add documentation to signal-handling functionsRoss Light
2018-03-02Change SigAction::flags to use from_bits_truncatedAntti Keränen
On Linux, if the signal trampoline code is in the C library, sigaction sets the SA_RESTORER flag (0x04000000) in the sa_flags field of old sigaction (see sigreturn(2)). This is not intended for application use and is missing from SaFlags, therefore from_bits fails and unwrapping panics the user program. This fix just drops the bits that are not defined in SaFlags.
