688: Support for OpenBSD r=Susurrus Fixes #685 These changes get nix building on OpenBSD 6.1. There is one failing test that I want a little guidance on: ``` error[E0308]: mismatched types --> src/sys/event.rs:333:30 | 333 | assert!(expected.data == actual.data()); | ^^^^^^^^^^^^^ expected i64, found isize ``` `KEvent::data` is: ``` pub fn data(&self) -> intptr_t { self.kevent.data as intptr_t } ``` I assume the test should be updated to cast to the expected type but wanted to confirm that before making the change.

There appears to be some interaction with test_pathconf_limited and another one when they are run in parallel, causing it to return ENOENT so the path has been changed from . to /.

2017-07-25Add WaitStatus::PtraceSyscall for use with PTRACE_O_TRACESYSGOODGeoffrey Thomas
The recommended way to trace syscalls with ptrace is to set the PTRACE_O_TRACESYSGOOD option, to distinguish syscall stops from receiving an actual SIGTRAP. In C, this would cause WSTOPSIG to return SIGTRAP | 0x80, but nix wants to parse that as an actual signal. Add another wait status type for syscall stops (in the language of the ptrace(2) manpage, "PTRACE_EVENT stops" and "Syscall-stops" are different things), and mask out bit 0x80 from signals before trying to parse it. Closes #550

2017-07-25Add 'bad' prefixes for read, write_*, and readwrite ioctlsBryant Mairs
2017-07-25Split ioctl!(write ...) into write_ptr and write_intBryant Mairs
There two different write semantics used with ioctls: one involves passing a pointer the other involves passing an int. Previously the ioctl! macro did not distinguish between these cases and left it up to the user to set the proper datatype. This previous version was not type safe and prone to errors. The solution here is to split the "write" variant into a "write_ptr" and "write_int" variant that makes the semantics more explicit and improves type safety by specifying arguments better.

693: fix some tests for Android r=asomers I tested the crate on an Android emulator and quite all the tests passed. Only 6 were failing. > failures: > > ---- sys::test_pthread::test_pthread_self stdout ---- > thread 'sys::test_pthread::test_pthread_self' panicked at 'assertion failed: tid > 0', test/sys/test_pthread.rs:6 > note: Run with `RUST_BACKTRACE=1` for a backtrace. > > ---- sys::test_socket::test_getsockname stdout ---- > thread 'sys::test_socket::test_getsockname' panicked at 'bind failed: Sys(EACCES)', /checkout/src/libcore/result.rs:859 > > ---- sys::test_socket::test_unixdomain stdout ---- > thread 'sys::test_socket::test_unixdomain' panicked at 'bind failed: Sys(EACCES)', /checkout/src/libcore/result.rs:859 > > ---- sys::test_termios::test_local_flags stdout ---- > thread 'sys::test_termios::test_local_flags' panicked at 'called `Option::unwrap()` on a `None` value', /checkout/src/libcore/option.rs:329 > > ---- test_net::test_if_nametoindex stdout ---- > thread 'test_net::test_if_nametoindex' panicked at 'assertion failed: if_nametoindex(&LOOPBACK[..]).is_ok()', test/test_net.rs:11 > > ---- test_unistd::test_mkstemp stdout ---- > thread 'test_unistd::test_mkstemp' panicked at 'mkstemp failed: ENOENT: No such file or directory', test/test_unistd.rs:73 This PR fixes 3 of those: - `test_pthread_self`: pthread_t is unsigned, so it can be negative (and it is often the case) - `test_if_nametoindex`: constant `LOOPBACK` is the same than on Linux - `test_mkstemp`: directory `/tmp` does not exist in Android Two are still failing (`test_unixdomain` and `test_getsockname`) because we need some special permissions on Android for playing with sockets. On a rooted physical device, they passed. So, if tests for Android are integrated in CI, we should try to embed the tests to run in an APK with requested permissions or find a way to give the permission to a native program. `test_local_flags` is still failing also because `O_LARGEFILE` is hardcoded and is not the right value in Android. Then `fcntl::OFlag::from_bits(flags).unwrap()` fails because this flag is then not recognised. I made a PR in `libc` so that we can rely on libc definitions for all `O_*` flags. (rust-lang/libc#683) Do you prefer to wait for this one to be fixed for this PR to merged as well ?

661: Allow doc attributes in ioctl r=asomers fixes #571 . Note that this is a breaking change because it also changes ``` ioctl!(some_name with 12); ``` to ``` ioctl!(bad some_name with 12); ``` This is to work around a bug in the rust compiler whereby rules around matching idents are overly strict. See https://github.com/rust-lang/rust/issues/24189 It doesn't break anything else though.
