This commit removes the call to `panic!("Some tests failed")` at the end of all
tests run when running with libtest. The panic is replaced with
`std::process::exit` to have a nonzero error code, but this change both:
1. Makes the test runner no longer print out the extraneous panic message at the
end of a failing test run that some tests failed. (this is already summarized
in the output of the test run).
2. When running tests with `RUST_BACKTRACE` set it removes an extraneous
backtrace from the output (only failing tests will have their backtraces in
the output.

This commit stabilizes the `std::time` module and the `Duration` type.
`Duration::span` remains unstable, and the `Display` implementation for
`Duration` has been removed as it is still being reworked and all trait
implementations for stable types are de facto stable.
This is a [breaking-change] to those using `Duration`'s `Display`
implementation.

This commit removes the injection of `std::env::args()` from `--test` expanded
code, relying on the test runner itself to call this funciton. This is more
hygienic because we can't assume that `std` exists at the top layer all the
time, and it meaks the injected test module entirely self contained.
|
|
These aren't really used for anything any more, so there doesn't seem to be much
reason to leave them around in the `rt` directory. There was some limiting of
threads spawned or tests when run under valgrind, but very little is run under
valgrind nowadays so there's also no real use keeping these around.

This library has no shims which are actually needed on Windows now, so translate
that last easy one into Rust and then don't link it at all on Windows.

This commit shards the all-encompassing `core`, `std_misc`, `collections`, and `alloc` features into finer-grained components that are much more easily opted into and tracked. This reflects the effort to push forward current unstable APIs to either stabilization or removal. Keeping track of unstable features on a much more fine-grained basis will enable the library subteam to quickly analyze a feature and help prioritize internally about what APIs should be stabilized.
A few assorted APIs were deprecated along the way, but otherwise this change is just changing the feature name associated with each API. Soon we will have a dashboard for keeping track of all the unstable APIs in the standard library, and I'll also start making issues for each unstable API after performing a first-pass for stabilization.

test: Fix a bug in bench result formatting
It would skip the middle part if it was 0, displaying a number a 1000
times too small. The MB/s number next to it gave it away.
Fixed it looks like this:
```
test h ... bench: 1,000,129 ns/iter (+/- 4,730)
```

This commit also deprecates the `as_string` and `as_slice` free functions in the
`string` and `vec` modules.

The output of individual tests can be captured now so it's safe to use
colorized output even when running tests in parallel. Closes #782.

This commit is an implementation of [RFC 1040][rfc] which is a redesign of the
currently-unstable `Duration` type. The API of the type has been scaled back to
be more conservative and it also no longer supports negative durations.
[rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1040-duration-reform.md
The inner `duration` module of the `time` module has now been hidden (as
`Duration` is reexported) and the feature name for this type has changed from
`std_misc` to `duration`. All APIs accepting durations have also been audited to
take a more flavorful feature name instead of `std_misc`.
Closes #24874

There were still some mentions of `~[T]` and `~T`, mostly in comments and debugging statements. I tried to do my best to preserve meaning, but I might have gotten some wrong-- I'm happy to fix anything :)
|

An automated script was run against the `.rs` and `.md` files,
subsituting every occurrence of `task` with `thread`. In the `.rs`
files, only the texts in the comment blocks were affected.

E.g. if `foo.rs` looks like
#![feature(test)]
extern crate test;
#[bench]
fn bar(b: &mut test::Bencher) {
b.iter(|| {
1
})
}
#[test]
fn baz() {}
#[bench]
fn qux(b: &mut test::Bencher) {
b.iter(|| {
panic!()
})
}
Then
$ rustc --test foo.rs
$ ./foo
running 3 tests
test baz ... ok
test qux ... FAILED
test bar ... ok
failures:
---- qux stdout ----
thread 'qux' panicked at 'explicit panic', bench.rs:17
failures:
qux
test result: FAILED. 2 passed; 1 failed; 0 ignored; 0 measured
$ ./foo --bench ba
running 2 tests
test baz ... ignored
test bar ... bench: 97 ns/iter (+/- 74)
test result: ok. 0 passed; 0 failed; 1 ignored; 1 measured
In particular, the two benchmark are being run as tests in the default
mode.
This helps for the main distribution, since benchmarks are only run with
`PLEASE_BENCH=1`, which is rarely set (and never set on the test bots),
and helps for code-coverage tools: benchmarks are run and so don't count
as dead code.
Fixes #15842.

This API was exercised in a few tests and mirrors the `from_str_radix`
functionality of the integer types.

This commit removes all the old casting/generic traits from `std::num` that are
no longer in use by the standard library. This additionally removes the old
`strconv` module which has not seen much use in quite a long time. All generic
functionality has been supplanted with traits in the `num` crate and the
`strconv` module is supplanted with the [rust-strconv crate][rust-strconv].
[rust-strconv]: https://github.com/lifthrasiir/rust-strconv
This is a breaking change due to the removal of these deprecated crates, and the
alternative crates are listed above.

for `Box<FnBox()>`. I found the alias was still handy because it is
shorter than the fully written type.
This is a [breaking-change]: convert code using `Invoke` to use `FnBox`,
which is usually pretty straight-forward. Code using thunk mostly works
if you change `Thunk::new => Box::new` and `foo.invoke(arg)` to
`foo(arg)`.

* Added methods `PathBuf::as_path`, `OsString::as_os_str`,
`String::as_str`, `Vec::{as_slice, as_mut_slice}`.
* Deprecates `OsStr::from_str` in favor of a new, stable, and more

This commit cleans out a large amount of deprecated APIs from the standard
library and some of the facade crates as well, updating all users in the
compiler and in tests as it goes along.
