Add missing url in sync structs
r? @frewsxcv
|

… instead of one of each of libcore and libstd_unicode.
Move the `utf8_char_width` function to `core::str`
under the `str_internals` unstable feature.

added Error and Display impl for std::ffi::FromBytesWithNulError
Fixes #39925.
This is my first PR, so I wasn't quite sure about the stability annotation.

Example for how to provide stdin using std::process::Command
Spawning a child process and writing to its stdin is a bit tricky due to
`as_mut` and having to use a limited borrow. An example for this might
help newer users.

Improve backtrace formating while panicking.
Fixes #37783.
Done:
- Fix alignment of file paths for better readability
- `RUST_BACKTRACE=full` prints all the informations (current behaviour)
- `RUST_BACKTRACE=(short|yes)` is the default and does:
- Skip irrelevant frames at the beginning and the end
- Remove function address
- Remove the current directory from the absolute paths
- Remove `::hfabe6541873` at the end of the symbols
- `RUST_BACKTRACE=(0|no)` disables the backtrace.
- `RUST_BACKTRACE=<everything else>` is equivalent to `short` for
backward compatibility.
- doc
- More uniform printing across platforms.
Removed, TODO in a new PR:
- Remove path prefix for libraries and libstd
Example of short backtrace:
```rust
fn fail() {
panic!();
}
fn main() {
let closure = || fail();
closure();
}
```
Short:
```
thread 'main' panicked at 'explicit panic', t.rs:2
Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
stack backtrace:
0: t::fail
at ./t.rs:2
1: t::main::{{closure}}
at ./t.rs:6
2: t::main
at ./t.rs:7
```
Full:
```
thread 'main' panicked at 'This function never returns!', t.rs:2

Switch Fuchsia to readdir (instead of readdir_r)
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.

Simplify/fix adaptive hashmap
Please see https://github.com/rust-lang/rust/pull/38368#issuecomment-280957863 for context.
The shift length math is broken. It turns out that checking for the shift length is complicated. Using simulations it's possible to see that a value of 2000 will only get probabilities down to ~1e-7 when the hashmap load factor is 90% (rust goes up to 90.9% as of today). That's probably not good enough to go into the stdlib with pluggable hashers.
So this PR simplify the adaptive behavior to only consider displacement, which is much safer and very useful by itself.
There's two comments because one of them is already being tested to be merged by bors.

Fix compilation on Redox
This updates the Redox sys module to fix compilation.
The functions peek and peek_from are added to TcpStream and UdpSocket as stubs. The sys::backtrace module is now included correctly

Follow rename of mx_handle_wait Magenta syscalls
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.

Clarify thread::Builder::stack_size docs
Add two pieces of information:
* the size is in bytes
* the actual stack size might be bigger.
Also change the example to use a more realistic value of 32 kilobytes.

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 😄

Fix spelling in hashmap comments
Fixing my bad english from #38368
Note to self: triple check spelling/grammar
|
|
This reverts commit 7f1d1c6d9a7be5e427bace30e740b16b25f25c92.
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!

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.
