807: Switch to libc definitons of errno constants r=Susurrus a=Susurrus
Still need to do OpenBSD and NetBSD. Primary goal with this first pass is to see what doesn't exist properly in `libc`.
Closes #487.

777: Use the real pipe2(2) on most targets r=asomers a=asomers
FreeBSD added pipe2(2) in version 10.0.
|
|
All supported non-Apple platforms now use the native syscall. Only ios
and macos lack it. Deprecate pipe2 on those platforms, because it's
impossible to guarantee atomicity with a userland implementation. It
was added in:
* DragonflyBSD 4.2
* FreeBSD 10.0
* NetBSD 6.0
* OpenBSD 5.7
|
|
This was doing testing for errno constants and a few other
types that is no longer necessary now that these types are
all tested within the libc project itself.

|
cc #664 (unsure if this is everything needed)
|
|
The libc_bitflags! macro was replaced with a non-recursive one supporting
only public structs. I could not figure out how to make the old macro work
with the upgrade, so I reworked part of the bitflags! macro directly to suit
our needs, much as the original recursive macro was made. There are no uses
of this macro for non-public structs, so this is not a problem for internal code.

This adds execveat() to `nix::unistd`. It uses the execveat(2) Linux
kernel syscall, which is available since 3.19.
This is a Linux-specific extension which is not covered by POSIX and
does not have any userland libc wrapper.

This introduces an `as_abstract()` getter to `UnixAddr` in order to
retrieve the name of an abstract unix socket.
This also adds tests around abstract addresses and clarify docs,
adding explicit semantics.

780: Add a test for ppoll r=Susurrus a=asomers

773: Add more accessors for AioCb r=asomers a=asomers
|
|
This fixes the following warning during run of cargo test
warning: variable does not need to be mutable
--> test/sys/test_aio.rs:16:13
|
16 | fn poll_aio(mut aiocb: &mut AioCb) -> Result<()> {
| ^^^^^^^^^

= note: #[warn(unused_mut)] on by default

test/test_stat.rs: test correct stat function
|
|
|
|
|
|
Previously, the `AioCb`'s `in_progress` field would erroneously be set
to `true`, even if the syscall had an error
Fixes #714
|
|
Printing a warning message to stderr isn't really appropriate, because
there's no way to guarantee that stderr is even valid. Nor is
aio_suspend necessarily an appropriate action to take.

746: Replace socket FFI with libc versions r=asomers a=Susurrus
Getting this up there to get some CI run on it. Replacing the `msghdr`, `cmsghdr`, and other FFI function declarations will be a little more involved so I wanted to run this through first.
|
|
745: Use upstream libc definitions for fcntl FFI r=asomers a=Susurrus
|
|
|
|
Used the libc_enum! macro to create enums for the ptrace event, request, and libc_bitflags for options constants defined in libc.
Also, replicated functionality to move from c_int to PtraceEvent enum in PR #728 as it appears to be abandoned.
Added utility function for detaching from tracee. Updated names and removed ptrace::ptrace namespace

`ptsname()` mutates global variables and mutating global variables is
always considered `unsafe` by Rust.

This adds fexecve() to `nix::unistd`. It is available in libc since 0.2.29.

700: Get rid of a lot of transmutes r=asomers
Most could be replaced by simple raw pointer casts (or even perfectly
safe coercions!).
cc #373
|
|
701: Calculate `nfds` parameter for `select` r=asomers
Doing this behind the scenes makes the API less error-prone and easier
to use. It should also fix my issue in https://github.com/nix-rust/nix/issues/679#issuecomment-316838148

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 /.

672: add poll module in Android r=Susurrus
`poll` functions are defined in Android as well.
libc is missing some constant, but once rust-lang/libc#663 is merged, it'll be good to merge here.
Closes #711
