2019-07-16Auto merge of #61946 - BaoshanPang:vxworks, r=alexcrichtonbors-2/+8372
port rust for vxWorks The supporting for vxWorks has been enabled in this branch. Although there are still a lots of work to do, I would like to upstream the code and fix the problems later. Please let me know if there is anything I have to do before upstream the code. r? @alexcrichton Thanks, Baoshan

2019-07-13simplify std::io::Write::write rustdocColin Arnott-1/+1
The std::io::Write::write method currensly suggests consumers guaranteed that `0 <= n <= buf.len()`, for `Ok(n)`, however `n` is of type `usize` causing the compiler to emit a warning: ``` warning: comparison is useless due to type limits --> lib.rs:6:18 | 6 | Ok(n) => 0 <= n && n <= output.len(), | ^^^^^^ | = note: #[warn(unused_comparisons)] on by default ``` This PR removes the suggestion to check `0 <= n` since it is moot. r? @steveklabnik

2019-07-11Rollup merge of #62425 - cyphar:linux-cloexec-use-fcntl, r=alexcrichtonMazdak Farrokhzad-0/+2
filedesc: don't use ioctl(FIOCLEX) on Linux All `ioctl(2)`s will fail on `O_PATH` file descriptors on Linux (because they use `&empty_fops` as a security measure against `O_PATH` descriptors affecting the backing file). As a result, `File::try_clone()` and various other methods would always fail with `-EBADF` on `O_PATH` file descriptors. The solution is to simply use `F_SETFD` (as is used on other unices) which works on `O_PATH` descriptors because it operates through the `fnctl(2)` layer and not through `ioctl(2)`s. Since this code is usually only used in strange error paths (a broken or ancient kernel), the extra overhead of one syscall shouldn't cause any dramas. Most other systems programming languages also use the fnctl(2) so this brings us in line with them. Fixes: rust-lang/rust#62314 Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>

2019-07-09Rollup merge of #62403 - SimonSapin:concat, r=alexcrichtonMazdak Farrokhzad-6/+0
Replace SliceConcatExt trait with inherent methods and SliceConcat helper trait Before this change `SliceConcatExt` was an unstable extension trait with stable methods. It was in the libstd prelude, so that its methods could be used on the stable channel. This replaces it with inherent methods, which can be used without any addition to the prelude. Since the methods are stable and very generic (with for example a return type that depends on the types of parameters), an helper trait is still needed. But now that trait does not need to be in scope for the methods to be used. Removing this depedency on the libstd prelude allows the methods to be used in `#![no_std]` crate that use liballoc, which does not have its own implicitly-imported prelude.

HashMap is UnwindSafe Fixes https://github.com/rust-lang/rust/issues/62301, a regression in 1.36.0-pre which was caused by hashbrown using `NonZero<T>` where the older hashmap used `Unique<T>`.

std: Move a process test out of libstd This commit moves a test out of libstd which is causing deadlocks on musl on CI. Looks like the recent update in musl versions brings in some internal updates to musl which makes `setgid` and `setuid` invalid to call after a `fork` in a multithreaded program. The issue seen here is that the child thread was attempting to grab a lock held by a nonexistent thread, meaning that the child process simply deadlocked causing the whole test to deadlock. This commit moves the test to its own file with no threads which should work.

Avoid mem::uninitialized() in std::sys::unix For `libc` types that will be initialized in FFI calls, we can just use `MaybeUninit` and then pass around raw pointers. For `sun_path_offset()`, which really wants `offset_of`, all callers have a real `sockaddr_un` available, so we can use that reference. r? @RalfJung
