Some older versions of LLDB have problems with multiple instances running in parallel. This commit makes sure we don't do that.

This commit changes the `io::process::Command` API to provide
fine-grained control over the environment:
* The `env` method now inserts/updates a key/value pair.
* The `env_remove` method removes a key from the environment.
* The old `env` method, which sets the entire environment in one shot,
is renamed to `env_set_all`. It can be used in conjunction with the
finer-grained methods. This renaming is a breaking change.
To support these new methods, the internal `env` representation for
`Command` has been changed to an optional `HashMap` holding owned
`CString`s (to support non-utf8 data). The `HashMap` is only
materialized if the environment is updated. The implementation does not
try hard to avoid allocation, since the cost of launching a process will
dwarf any allocation cost.
This patch also adds `PartialOrd`, `Eq`, and `Hash` implementations for
`CString`.

This change registers new snapshots, allowing `*T` to be removed from the language. This is a large breaking change, and it is recommended that if compiler errors are seen that any FFI calls are audited to determine whether they should be actually taking `*mut T`.

This commit removes superfluous to_string calls from various places
|
|
|
|
Replace its usage with byte string literals, except in `bytes!()` tests.
Also add a new snapshot, to be able to use the new b"foo" syntax.
The src/etc/2014-06-rewrite-bytes-macros.py script automatically
rewrites `bytes!()` invocations into byte string literals.
Pass it filenames as arguments to generate a diff that you can inspect,
or `--apply` followed by filenames to apply the changes in place.
Diffs can be piped into `tip` or `pygmentize -l diff` for coloring.

This involved a few changes to the local build system:
* Makefiles now prefer our own LD_LIBRARY_PATH over the user's LD_LIBRARY_PATH
in order to support building rust with rust already installed.
* The compiletest program was taught to correctly pass through the aux dir as a
component of LD_LIBRARY_PATH in more situations.
This change was spliced out of #14832 to consist of just the fixes to running
tests without an rpath setting embedded in executables.

This obsoletes the old `to_err_msg` method. Replace
println!("Error: {}", failure.to_err_msg())
let string = failure.to_err_msg();
with
println!("Error: {}", failure)
let string = failure.to_str();

This leaves a deprecated reexport in place temporarily.
Closes #1457.

It uses the same behavior as rustc's.

Do this to avoid warnings on post-stage0 builds.

This commit carries out the request from issue #14678:
> The method `Iterator::len()` is surprising, as all the other uses of
> `len()` do not consume the value. `len()` would make more sense to be
> called `count()`, but that would collide with the current
> `Iterator::count(|T| -> bool) -> unit` method. That method, however, is
> a bit redundant, and can be easily replaced with
> `iter.filter(|x| x < 5).count()`.
> After this change, we could then define the `len()` method
> on `iter::ExactSize`.
Closes #14678.

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.

This is part of the ongoing renaming of the equality traits. See #12517 for more
details. All code using Eq/Ord will temporarily need to move to Partial{Eq,Ord}
or the Total{Eq,Ord} traits. The Total traits will soon be renamed to {Eq,Ord}.

See #13983 and #14000.
Fix was originally authored by alexcrichton and then rebased a couple
times by pnkfelix, most recently atop PR 13954.

Regarding the change to librustdoc/lib.rs, to do `map_err` before
unwrapping a `TqskResult`: I do not understand how master is passing
without this change or something like it, since `Box<Any:Send>` does
not implement `Show`. (Is this something that is only a problem for
the snapshot stage0 compiler?) Still, the change I have put in here
(which was added as part of a rebase after alex's review) seems
harmless to me to apply to rustdoc at all stages, since a call to
`unwrap` is just going to `fail!` on the err case anyway.

This plugs a leak where resolve was treating enums defined in parent modules as
in-scope for all children modules when resolving a pattern identifier. This
eliminates the code path in resolve entirely.
If this breaks any existing code, then it indicates that the variants need to be
explicitly imported into the module.
Closes #14221

This allows writing a regex to filter tests more precisely, rather than having to list long paths e.g.
```
$ ./stdtest-x86_64-unknown-linux-gnu 'vec.*clone'
running 2 tests
test vec::tests::test_clone ... ok
test vec::tests::test_clone_from ... ok
test result: ok. 2 passed; 0 failed; 0 ignored; 0 measured
```
The regex change is fully backwards compatible, since test names are Rust
identifiers + `:`, and hence not special regex characters.
(See commits for details.)

The existing APIs for spawning processes took strings for the command
and arguments, but the underlying system may not impose utf8 encoding,
so this is overly limiting.
The assumption we actually want to make is just that the command and
arguments are viewable as [u8] slices with no interior NULLs, i.e., as
CStrings. The ToCStr trait is a handy bound for types that meet this
requirement (such as &str and Path).
However, since the commands and arguments are often a mixture of
strings and paths, it would be inconvenient to take a slice with a
single T: ToCStr bound. So this patch revamps the process creation API
to instead use a builder-style interface, called `Command`, allowing
arguments to be added one at a time with differing ToCStr
implementations for each.
The initial cut of the builder API has some drawbacks that can be
addressed once issue #13851 (libstd as a facade) is closed. These are
detailed as FIXMEs.
Closes #11650.

There's no need to include this specific flag just for android. We can
already deal with what it tries to solve by using -C linker=/path/to/cc
and -C ar=/path/to/ar. The Makefiles for rustc already set this up when
we're crosscompiling.
I did add the flag to compiletest though so it can find gdb. Though, I'm
pretty sure we don't run debuginfo tests on android anyways right now.

This implements set_timeout() for std::io::Process which will affect wait()
operations on the process. This follows the same pattern as the rest of the
timeouts emerging in std::io::net.
The implementation was super easy for everything except libnative on unix
(backwards from usual!), which required a good bit of signal handling. There's a
doc comment explaining the strategy in libnative. Internally, this also required
refactoring the "helper thread" implementation used by libnative to allow for an
extra helper thread (not just the timer).
This is a breaking change in terms of the io::Process API. It is now possible
for wait() to fail, and subsequently wait_with_output(). These two functions now
return IoResult<T> due to the fact that they can time out.
Additionally, the wait_with_output() function has moved from taking `&mut self`
to taking `self`. If a timeout occurs while waiting with output, the semantics
are undesirable in almost all cases if attempting to re-wait on the process.
Equivalent functionality can still be achieved by dealing with the output
handles manually.

* Added `// no-pretty-expanded` to pretty-print a test, but not run it through
the `expanded` variant.
* Removed #[deriving] and other expanded attributes after they are expanded
* Removed hacks around &str and &&str and friends (from both the parser and the
pretty printer).
* Un-ignored a bunch of tests
|

After testing `--pretty normal`, it tries to run `--pretty expanded` and
typecheck output.
Here we don't check convergence since it really diverges: for every
iteration, some extra lines (e.g.`extern crate std`) are inserted.
Some tests are `ignore-pretty`-ed since they cause various issues
with `--pretty expanded`.
