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.

2021-07-24unistd: Add conversion from User to libc::passwdorvij
Add From<User> for libc::passwd trait implementation to convert a User into a libc::passwd Implementation consumes the User struct, giving ownership over the internal members to the libc::passwd struct Add the User::gecos field to 64-bit Android builds, since it is supported by libc::passwd for those builds

2021-07-09Fix fork test and enable doc testJim Newsome
Replaces `println!` with raw `libc::write`. `println!` isn't guaranteed to be async-signal-safe, and almost certainly *isn't* due to internal buffering and locking. Adds a call to `libc::_exit` in the child arm, so that it doesn't fall through and start executing the parent code. Adds a call to `waitpid` in the parent arm, to clean up the child process. Removes the `no_run` directive, so that it's run in the doc tests.
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

* Fix race conditions in the tests. Two tests were grabbing a mutex but immediately dropping it. Thank you, Clippy. * Remove vestigial Windows support. Remove some code added to support Windows in 2015. Nix is no longer intended to ever run on Windows. * Various other minor Clippy lints.

2021-03-25unistd: Increase maximum passwd/group buffer to 1MBGeoffrey Thomas
We have one UNIX group that contains most of our users whose size is about 20 kB, so `Group::from_name` is failing with ERANGE. The discussion on PR #864 suggests that 1 MB is a reasonable maximum - it follows what FreeBSD's libc does. (glibc appears to have no maximum on the _r function and will just double the buffer until malloc fails, but that's not particularly Rusty.)

2020-12-09Fix intermittency in the doc test for alarmAlan Somers
On Cirrus CI, this test would sometimes fail, probably due to pause being awoken by SIGRT_1. sigwait is a superior alternative to pause. Fixes #1354
2020-12-06Switch all builds from Travis to CirrusAlan Somers
Travis has been super-slow lately (> 6 hours per build). Cirrus is much faster: about 20 minutes. Cirrus also has slightly better test coverage, mainly because it doesn't use SECCOMP. Also, * Fix the Redox CI build. The old Travis configuration didn't actually build for Redox, so we never noticed that Redox can't be built with a stable compiler. Thanks to @coolreader18 for finding this. * Disable the udp_offload tests on cross-tested platforms. These tests are failing with ENOPROTOOPT in Cirrus-CI. I suspect it's due to a lack of support in QEMU. These tests were skipped on Travis because its kernel was too old. * Fix require_kernel_version on Cirrus-CI. Cirrus reports the Linux kernel version as 4.19.112+, which the semver crate can't handle. * Fix test_setfsuid on Cirrus. When run on Cirrus, it seems like the file in /tmp gets deleted as soon as it's closed. Probably an overzealous temporary file cleaner. Use /var/tmp, because no temporary file cleaner should run in there. * Skip mount tests on Cirrus. They fail for an unknown reason. Issue #1351 * Skip the AF_ALG tests on Cirrus-CI Issue #1352

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

2020-04-06unistd: avoid infinite loop caused by reserve_double_buffer_sizeSteven Danna
Functions such as Group::from_anything use reserve_double_buffer_size in a loop, expecting it to return ERANGE if the passed limit is reached. However, the returned vector is passed as pointer to a libc function that writes data into memory and doesn't update the length of the Vec. Because of this, the previous code would never return ERANGE and the calling loops would never exit if they hit a case where the required buffer was larger than the maximum buffer. This fixes the problem by checking the capacity rather than the length. Signed-off-by: Steven Danna <steve@chef.io>
