Now that the necessary associated types exist for the `IntoIterator` trait this
commit stabilizes the trait as-is as well as all existing implementations.
The `connect_error` test check if connecting to "0.0.0.0:1" works (it
shouldn't). And in case of error, the test expects a `ConnectionRefused`
error.
Under OpenBSD, trying to connect to "0.0.0.0" isn't a `ConnectionRefused`:
it is an `InvalidInput` error.
The patch allow the error to be `ConnectionRefused` or `InvalidInput`.
Another possibility is to check connecting to "127.0.0.1:1" and expects only `ConnectionRefused` error.
This commit exposes the `is_sep` function and `MAIN_SEP` constant, as
well as Windows path prefixes. The path prefix enum is safely exposed on
all platforms, but it only yielded as a component for Windows.
Exposing the prefix enum as part of prefix components involved changing
the type from `OsStr` to the `Prefix` enum, which is a:

* Move the type parameter on the `AsciiExt` trait to an associated type named
`Owned`.
* Move `ascii::escape_default` to using an iterator.
This is a breaking change due to the removal of the type parameter on the
`AsciiExt` trait as well as the modifications to the `escape_default` function
to returning an iterator. Manual implementations of `AsciiExt` (or `AsciiExt`
bounds) should be adjusted to remove the type parameter and using the new
`escape_default` should be relatively straightforward.

This commit performs a stabilization pass over the `std::ascii` module taking
the following actions:
* the module name is now stable
* `AsciiExt` is now stable after moving its type parameter to an `Owned`
associated type
* `AsciiExt::is_ascii` is now stable
* `AsciiExt::to_ascii_uppercase` is now stable
* `AsciiExt::to_ascii_lowercase` is now stable
* `AsciiExt::eq_ignore_ascii_case` is now stable
* `AsciiExt::make_ascii_uppercase` is added to possibly replace
`OwnedAsciiExt::into_ascii_uppercase` (similarly for lowercase variants).
* `escape_default` now returns an iterator and is stable
* `EscapeDefault` is now stable
Trait implementations are now also marked stable.
Primarily it is still unstable to *implement* the `AsciiExt` trait due to it
containing some unstable methods.
[breaking-change]
Previously an implementation of a stable trait allows implementations of
unstable methods. This updates the stability pass to ensure that all items of an
impl block of a trait are indeed stable on the trait itself.
Now that the necessary associated types exist for the `IntoIterator` trait this
commit stabilizes the trait as-is as well as all existing implementations.
This is a more introductory document, suitable for Part II. The arcane details move to an "Advanced macros" chapter in Part III.

Pass features along during expansion
Use the set of passed features to detect uses of feature-gated macros without the corresponding feature enabled.
Fix#22234.
----
Also, the framework this add (passing along a reference to the features in the expansion context) is a necessary precursor for landing a properly feature-gated desugaring-based overloaded-`box` and placement-`in` (#22181).

This is fixing a bug, but since there might be code out there that is unknowingly taking advantage of that bug, I feel obligated to mark this as a:

Some examples for `std::num::Float`
~~This is WIP for making examples for `f32`. This probably won't pass `make tidy` and I'm not sure which `f32` needs documentation. https://github.com/rust-lang/rust/issues/22025 shows 2 sets of `f32` which seems split between `core` and `std`. I'm not sure which should be documented but I started doing a couple from `std`. Easy to move if that's where they go...~~
~~Gotta build it eventually to actually see if the docs actually appear where I think they will or if I'm just disillusioned.~~

The test \"signal_reported_right\" send a signal `1` to `/bin/sh`, and check
the status code to check if the signal is reported right.
Under OpenBSD, the signal `1` (`SIGHUP`) is catched by `/bin/sh`,
resulting the test failed.
Use the uncatchable signal `9` (`SIGKILL`) for test.
This commit mostly replaces some of the uses of os::args with env::args.
This, for obvious reasons is based on top of #22400. Do not r+ before that lands.
When matching against strings/slices, we call the comparison function
for strings, which takes two string slices by value. The slices are
passed in memory, and currently we just pass in a pointer to the
original slice. That can cause misoptimizations because we emit a call
to llvm.lifetime.end for all by-value arguments at the end of a
function, which in this case marks the original slice as dead.
So we need to properly create copies of the slices to pass them to the
comparison function.
Fixes#22008
This redux of CONTRIBUTING.md adds in more information, including
subsuming both compliment-bugreport.md and Note-development-policy
in the wiki.
I only glanced at the broad TOC of Note-development-policy, and did
not use the text as the basis for the re-write. This will then address
the last outstanding part of #5831.
The connect_error test check if connecting to "0.0.0.0:1" works (it
shouldn't). And in case of error, the test expects a ConnectionRefused
error.
Under OpenBSD, trying to connect to "0.0.0.0" isn't a ConnectionRefused:
it is an InvalidInput error.
The patch allow the error to be ConnectionRefused or InvalidInput.
The first commit adds a short note which I believe will reduce worries in people who work with closures very often and read the Rust book for their first time.
The second commit consists solely of tiny typo fixes. In some cases, I changed "logical" quotations like

to

because the latter seems to be the prevalent style in the book.
Changes std::os::errno to return i32, the return type used by the function being delegated to.
This is my first contribution, so feel free to give me advice. I'll be happy to correct things.
Since `tr` converts lowercase to uppercase according to system locale using `LC_CTYPE` environment variable; on some locales, rustup.sh fails to use correct variables names, thus deletes temporarily downloaded files and gives a meaningless error as shown below. This a simple fix which explictly sets `LC_CTYPE` as `C`.
Here is what happens without the fix:

Notice how `i` wasn't replaced with `I`.
Rust is installed as usual after the fix. Tested on Ubuntu x86 12.04 LTS.
I'm not exactly sure if setting LC_CTYPE is the best solution, but there's that.
