The readdir_r function is deprecated on newer Posix systems because of
various problems, and not implemented at all for Fuchsia. There are
already implementations using both, and this patch switches Fuchsia
over to the readdir-based one.
Fixes#40021 for Fuchsia, but that issue also contains discussion of
what should happen for other Posix systems.
Changed stability annotations for the new Error and Display impls
for std::ffi::FromBytesWithNulError as they aren't subject to
stability the same way.
Reenable linkchecker for books
In some senses, this is a revert of https://github.com/rust-lang/rust/pull/39633/commits/cacb3bc9c741a7d41a1085af850cd3ff852307f5#diff-b64563d143f859565c8357a28ef81101R212; we disabled linkchecker for the book because the links were added by JavaScript. Now, that's fixed upstream, and so we can re-enable the checker.
This also involves two other fixes: we have to check for `name`s as well as `id`s for links, and the linking algorithm of mdBook changed to the same as rustdoc's, so we change some links back.
~~~This isn't quite ready yet; it's [depending on a PR of mine to mdBook](https://github.com/azerupi/mdBook/pull/209). After that's released, this should be the last of these kinds of shenanigans~~~ 😄
This is good to go 😄
This reverts commit 7f1d1c6d9a.
The original commit was created because mdBook and rustdoc had
different generation algorithms for header links; now with
https://github.com/rust-lang/rust/pull/39966 , the algorithms
are the same. So let's undo this change.
... when I came across this problem, I said "eh, this isn't fun,
but it doesn't take that long." I probably should have just actually
taken the time to fix upstream, given that they were amenable. Oh
well!
The mx_handle_wait_* syscalls in Magenta were renamed to
mx_object_wait. The syscall is used in the Magenta/Fuchsia
implementation of std::process, to wait on child processes.
In addition, this patch enables the use of the system provided
libbacktrace library on Fuchsia targets. Symbolization is not yet
working, but at least it allows printing hex addresses in a backtrace
and makes building succeed when the backtrace feature is not disabled.
sys/mod doc update and mod import order adjust
* Some doc updates.
* Racer currently use the first mod it finds regardless of cfg attrs. Moving #[cfg(unix)] up should be a temporary tweak that works as expected for more people.
- `RUST_BACKTRACE=full` prints all the informations (old behaviour)
- `RUST_BACKTRACE=(0|no)` disables the backtrace.
- `RUST_BACKTRACE=<everything else>` (including `1`) shows a simplified
backtrace, without the function addresses and with cleaned filenames
and symbols. Also removes some unneded frames at the beginning and the
end.
Fixes#37783.

Conversions between CStr, OsStr, Path and boxes
This closes a bit of the inconsistencies between `CStr`, `OsStr`, `Path`, and `str`, allowing people to create boxed versions of DSTs other than `str` and `[T]`.
Full list of additions:
* `Default` for `Box<str>`, `Box<CStr>`, `Box<OsStr>`, and `Box<Path>` (note: `Default` for `PathBuf` is already implemented)
* `CString::into_boxed_c_str` (feature gated)
* `OsString::into_boxed_os_str` (feature gated)
* `Path::into_boxed_path` (feature gated)
* `From<&CStr> for Box<CStr>`
* `From<&OsStr> for Box<OsStr>`
* `From<&Path> for Box<Path>`
This also includes adding the internal methods:
* `sys::*::os_str::Buf::into_box`
* `sys::*::os_str::Slice::{into_box, empty_box}`
* `sys_common::wtf8::Wtf8Buf::into_box`
* `sys_common::wtf8::Wtf8::{into_box, empty_box}`
Port books to mdbook
Part of https://github.com/rust-lang/rust/issues/39588
blocked on https://github.com/rust-lang/rust/pull/39431
As a first step towards the bookshelf, we ~vendor mdbook in-tree and~ port our books to it. Eventually, both of these books will be moved out-of-tree, but the nightly book will rely on doing the same thing. As such, this intermediate step is useful.

Add equivalents of C's <ctype.h> functions to AsciiExt.
* `is_ascii_alphabetic`
* `is_ascii_uppercase`
* `is_ascii_lowercase`
* `is_ascii_alphanumeric`
* `is_ascii_digit`
* `is_ascii_hexdigit`
* `is_ascii_punctuation`
* `is_ascii_graphic`
* `is_ascii_whitespace`
* `is_ascii_control`
This addresses issue #39658.
Lightly tested on x86-64-linux. tidy complains about the URLs in the documentation making lines too long, I don't know what to do about that.
