Before, tests for dynamic regexes ran during stage1 and tests for
native regexes ran during stage2. But the buildbots don't test stage1,
so now both dynamic and native tests are run during stage2.
Closes#13740.
Clarifies the interaction of `is_dir`, `is_file` and `exists` with
symbolic links. Adds a convenience `lstat` function alongside of
`stat`. Removes references to conditions.
Closes issue #12583.

This addresses the ICE from #13763, but it does not allow the test to compile,
due to #13768. An alternate test was checked in in the meantime.

Follow-up on issue #13297 and PR #13710. Instead of following the (confusing) C/C++ approach
of using `MIN_VALUE` for the smallest *positive* number, we introduce `MIN_POS_VALUE` (and
in the Float trait, `min_pos_value`) to represent this number.
This patch also removes a few remaining redundantly-defined constants that were missed last
time around.
It didn't work because it tried to call itself but symbols are not
exported as default in executables.
Note that `fun5` is not internal anymore since it is in library.
Second commit removes/updates some old tests.

Implements [RFC 7](https://github.com/rust-lang/rfcs/blob/master/active/0007-regexps.md) and will hopefully resolve#3591. The crate is marked as experimental. It includes a syntax extension for compiling regexps to native Rust code.
Embeds and passes the `basic`, `nullsubexpr` and `repetition` tests from [Glenn Fowler's (slightly modified by Russ Cox for leftmost-first semantics) testregex test suite](http://www2.research.att.com/~astopen/testregex/testregex.html). I've also hand written a plethora of other tests that exercise Unicode support, the parser, public API, etc. Also includes a `regex-dna` benchmark for the shootout.
I know the addition looks huge at first, but consider these things:
1. More than half the number of lines is dedicated to Unicode character classes.
2. Of the ~4,500 lines remaining, 1,225 of them are comments.
3. Another ~800 are tests.
4. That leaves 2500 lines for the meat. The parser is ~850 of them. The public API, compiler, dynamic VM and code generator (for `regexp!`) make up the rest.
I decided to put architecture constants in another mod. They are not used, so a part of me is thinking of just getting rid of them altogether. The rest should be similar to what @brson wants.
Fixes#13536
This adds support for connecting to a unix socket with a timeout (a named pipe
on windows), and accepting a connection with a timeout. The goal is to bring
unix pipes/named sockets back in line with TCP support for timeouts.
Similarly to the TCP sockets, all methods are marked #[experimental] due to
uncertainty about the type of the timeout argument.
This internally involved a good bit of refactoring to share as much code as
possible between TCP servers and pipe servers, but the core implementation did
not change drastically as part of this commit.

moves computation. ExprUseVisitor is a visitor that walks the AST for a
function and calls a delegate to inform it where borrows, copies, and moves
occur.
In this patch, I rewrite the gather_loans visitor to use ExprUseVisitor, but in
future patches, I think we could rewrite regionck, check_loans, and possibly
other passes to use it as well. This would refactor the repeated code between
those places that tries to determine where copies/moves/etc occur.

The change in #13600 was incorrect, containing a bad regular expression;
inside an indent function, errors are silently ignored (and the ``~=``
operation will return 0), so it just always failed, causing the cases
that were supposed to be caught to not be caught and making things like
the ``match`` example shown above or struct field definitions regress.
I have fixed the regular expression to what it should have been. This is
still imperfect, of course, not handling cases like where the first
argument to a function is a function call (``foo(bar(),``), but it'll do
for now.

I have a general request to make of reviewers about any changes made to `src/etc/vim`: **please tell me**. As a general rule I want to review them. (I’ll make an exception for changes the prelude; it needs fixing from time to time when some people don’t update the syntax file, anyway.)

The `walk_dir` iterator was simulating a queue using a vector (in particular, using `shift`),
leading to O(n^2) performance. Since the order was not well-specified (see issue #13411),
the simplest fix is to use the vector as a stack (and thus yield a depth-first traversal).
This patch does exactly that, and adds a test checking for depth-first behavior.
Note that the underlying `readdir` function does not specify any particular order, nor
does the system call it uses.
Closes#13411.
A new flag to the test runner, --nocapture, can be passed to instruct that the
output of tests should not be captured by default. The behavior can also be
triggered via a RUST_TEST_NOCAPTURE environment variable being set.

the simplest fix is to use the vector as a stack (and thus yield a depth-first traversal).
This patch does exactly that. It leaves the order as originally specified -- "some top-down
order" -- and adds a test to ensure a top-down traversal.

This update brings a few months of changes, but primarily a fix for the
following situation.
When creating a handle to stdin, libuv used to set the stdin handle to
nonblocking mode. This would end up affect this stdin handle across all
processes that shared it, which mean that stdin become nonblocking for everyone
using the same stdin. On linux, this also affected *stdout* because stdin/stdout
roughly point at the same thing.
This problem became apparent when running the test suite manually on a local
computer. The stdtest suite (running with libgreen) would set stdout to
nonblocking mode (as described above), and then the next test suite would always
fail for a printing failure (because stdout was returning EAGAIN).
This has been fixed upstream, joyent/libuv@342e8c, and this update pulls in this
fix. This also brings us in line with a recently upstreamed libuv patch.

Specifically, the method parameter cardinality mismatch or missing
method error message span now gets method itself exactly. It was the
whole expression.

This patch removes the special auto-rooting for `@` from the borrow checker. With `@` moving into a library, it doesn't make sense to keep this code around anymore. It also simplifies `trans` by removing root checking from there

Closes: #11586
Some of the constant values in std::f32 were incorrectly copied from
std::f64. More broadly, both modules defined their constants redundantly
in two places, which is what led to the bug. Moreover, the specs for
some of the constants were incorrect, even when the values were correct.
Closes#13297. Closes#11537.
This is really only useful for #[cfg()]. For example:
```rust
enum Foo {
Bar,
Baz,
#[cfg(blob)]
Blob
}
fn match_foos(f: &Foo) {
match *f {
Bar => {}
Baz => {}
#[cfg(blob)]
Blob => {}
}
}
```
This is a kind of weird place to allow attributes, so it should probably
be discussed before merging.
