This time we're not promoting anything directly to 'stable', but instead promoting functions we're happy with to 'unstable'. They'll become stable in another pass later.
* null and mut_null are unstable. Their names may change if the unsafe
pointer types change.
* copy_memory and copy_overlapping_memory are unstable. We think they
aren't going to change.
* set_memory and zero_memory are experimental. Both the names and
the semantics are under question.
* swap and replace are unstable and probably won't change.
* read is unstable, probably won't change
* read_and_zero is experimental. It's necessity is in doubt.
* mem::overwrite is now called ptr::write to match read and is
unstable. mem::overwrite is now deprecated
* array_each, array_each_with_len, buf_len, and position are
all deprecated because they use old style iteration and their
utility is generally under question.
Note that `mem::overwrite`, which was just declared stable last week, is deprecated now in favor of `ptr::write`. Woo!

The most frequent failure for our travis builds is running into the timeout
limits when building the compiler itself. Building librustc takes a very long
amount of time, often hitting the 10 minutes with no output threshold that
travis imposes on us.
This commit switches the relevant `make` step to being wrapped in the
`travis_wait` command [1]. This command will print something once a minute so as
to not time out a build.
This will hopefully enable us to have fewer flaky builds on travis!

This fix suppresses dead_code warnings from code generated by regex! when
the result of regex! is unused. Correct behavior should be a single
unused variable warning.
Regression tests are included for both `let` and `static` bound regex!
values.
These are a pain to rebase, so I'm separating this from the rest of my work.
Nothing controversial here, just some simple refactoring and removal of an
unused entry in the token table. Brings the lexer into 2012 with methods!
A few notable improvements were implemented to cut down on the number of aborts
triggered by the standard library when a local task is not found.
* Primarily, the unwinding functionality was restructured to support an unsafe
top-level function, `try`. This function invokes a closure, capturing any
failure which occurs inside of it. The purpose of this function is to be as
lightweight of a "try block" as possible for rust, intended for use when the
runtime is difficult to set up.
This function is *not* meant to be used by normal rust code, nor should it be
consider for use with normal rust code.
* When invoking spawn(), a `fail!()` is triggered rather than an abort.
* When invoking LocalIo::borrow(), which is transitively called by all I/O
constructors, None is returned rather than aborting to indicate that there is
no local I/O implementation.
* Invoking get() on a TLD key will return None if no task is available
* Invoking replace() on a TLD key will fail if no task is available.
A test case was also added showing the variety of things that you can do without
a runtime or task set up now. In general, this is just a refactoring to abort
less quickly in the standard library when a local task is not found.
Unlike ImmutableClonableVector::permutations() which returns an iterator,
cloning the entire array each iteration, these methods mutate the vector in-place.
For that reason, these methods are much faster; between 35-55 times faster,
depending on the benchmark. They also generate permutations in lexicographical order.
Refactored the load factor and the minimum capacity out of HashMap.
The size of HashMap<K, V> is now 64 bytes by default on a 64-bit platform
(or 48 bytes, that is 2 words less, with FNV)
Added a documentation in a few places to clarify the behavior.
An empty regex is a valid regex that always matches. This behavior
is consistent with at least Go and Python.
A couple regression tests are included.
I'd just assume that an empty regex is an invalid regex and that an error should be returned (I can't think of any reason to use an empty regex?), but it's probably better to be consistent with other regex libraries.
This commit removes the <M: Any + Send> type parameter from Option::expect in
favor of just taking a hard-coded `&str` argument. This allows this function to
move into libcore.
Previous code using strings with `expect` will continue to work, but code using
this implicitly to transmit task failure will need to unwrap manually with a
`match` statement.
[breaking-change]
Closes#14008
Example URL in CrateId documentation is:
`gihub.com/mozilla/rust`
Instead of:
`github.com/mozilla/rust`
Also update libsyntax/crateid.rs licensing header for 2014.
As part of removing `pub use` glob, two extra import globs were
injected to make `quote_expr!` work. However the globs caused
`unused_import` warning in some places.
Quasiquoter needed the globs since it generated idents (e.g. `TyU`)
rather than absolute paths (`::syntax::ast::TyU`).
This patch removes the extra globs and makes quasiquoter use absolute
paths.
Fixes#14618

Now that rustdoc understands proper language tags
as the code not being Rust, we can tag everything
properly. `norust` as a negative statement is a bad
tag.
This change tags examples in other languages by
their language. Plain notations are marked as `text`.
Console examples are marked as `console`.
Also fix markdown.rs to not highlight non-rust code.
Amends the documentation to reflect the new
behaviour.
