This fixes 4 bugs that prevented the extra::arc and extra::sync tests from passing on the new runtime. * In ```Add SendDeferred trait``` I add a non-rescheduling ```send_deferred``` method to our various channel types. The ```extra::sync``` concurrency primitives need this guarantee so they can send while inside of an exclusive. (This fixes deterministic deadlocks seen with ```RUST_THREADS=1```.) * In "Fix nasty double-free bug" I make sure that a ```ChanOne``` suppresses_finalize *before* rescheduling away to the receiver, so in case it gets a kill signal upon coming back, the destructor is inhibited as desired. (This is pretty uncommon on multiple CPUs but showed up always with ```RUST_THREADS=1```.) * In ```Fix embarrassing bug where 'unkillable' would unwind improperly``` I make sure the task's unkillable counter stays consistent when a kill signal is received right at the start of an unkillable section. (This is a very uncommon race and can only occur with multiple CPUs.) * In ```Don't fail from kill signals if already unwinding``` I do pretty much what it says on the tin. Surprising that it took the whole suite of sync/arc tests to expose this. The other two commits are cleanup. r @brson
The Rust Programming Language
This is a compiler for Rust, including standard libraries, tools and documentation.
Quick Start
Windows
Note: Windows users should read the detailed getting started notes on the wiki. Even when using the binary installer the Windows build requires a MinGW installation, the precise details of which are not discussed here.
Linux / OS X
-
Install the prerequisites (if not already installed)
- g++ 4.4 or clang++ 3.x
- python 2.6 or later (but not 3.x)
- perl 5.0 or later
- gnu make 3.81 or later
- curl
-
Download and build Rust You can either download a tarball or build directly from the repo.
To build from the tarball do:
$ curl -O http://static.rust-lang.org/dist/rust-0.7.tar.gz $ tar -xzf rust-0.7.tar.gz $ cd rust-0.7Or to build from the repo do:
$ git clone https://github.com/mozilla/rust.git $ cd rustNow that you have Rust's source code, you can configure and build it:
$ ./configure $ make && make installYou may need to use
sudo make installif you do not normally have permission to modify the destination directory. The install locations can be adjusted by passing a--prefixargument toconfigure. Various other options are also supported, pass--helpfor more information on them.When complete,
make installwill place several programs into/usr/local/bin:rustc, the Rust compiler;rustdoc, the API-documentation tool, andrustpkg, the Rust package manager and build system. -
Read the tutorial.

Enjoy!
Notes
Since the Rust compiler is written in Rust, it must be built by a precompiled "snapshot" version of itself (made in an earlier state of development). As such, source builds require a connection to the Internet, to fetch snapshots, and an OS that can execute the available snapshot binaries.
Snapshot binaries are currently built and tested on several platforms:
- Windows (7, Server 2008 R2), x86 only
- Linux (various distributions), x86 and x86-64
- OSX 10.6 ("Snow Leopard") or greater, x86 and x86-64
You may find that other platforms work, but these are our "tier 1" supported build environments that are most likely to work.
Rust currently needs about 1.8G of RAM to build without swapping; if it hits swap, it will take a very long time to build.
There is lots more documentation in the wiki.
