Alex Crichton e4c6523c65 Fire fewer homing missiles This optimizes the `home_for_io` code path by requiring fewer scheduler operations in some situtations. When moving to your home scheduler, this no longer forces a context switch if you're already on the home scheduler. Instead, the homing code now simply pins you to your current scheduler (making it so you can't be stolen away). If you're not on your home scheduler, then we context switch away, sending you to your home scheduler. When the I/O operation is done, then we also no longer forcibly trigger a context switch. Instead, the action is cased on whether the task is homed or not. If a task does not have a home, then the task is re-flagged as not having a home and no context switch is performed. If a task is homed to the current scheduler, then we don't do anything, and if the task is homed to a foreign scheduler, then it's sent along its merry way. I verified that there are about a third as many `write` syscalls done in print operations now. Libuv uses write to implement async handles, and the homing before and after each I/O operation was triggering a write on these async handles. Additionally, using the terrible benchmark of printing 10k times in a loop, this drives the runtime from 0.6s down to 0.3s (yay!).		2013-10-25 16:18:01 -07:00

The Rust Programming Language

This is a compiler for Rust, including standard libraries, tools and documentation.

Quick Start

Windows

Download and use the installer.
Read the tutorial.
Enjoy!

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-0.8.tar.gz
 $ tar -xzf rust-0.8.tar.gz
 $ cd rust-0.8
```
Or to build from the repo do:
```
 $ git clone https://github.com/mozilla/rust.git
 $ cd rust
```
Now that you have Rust's source code, you can configure and build it:
```
 $ ./configure
 $ make && make install
```
You may need to use sudo make install if you do not normally have permission to modify the destination directory. The install locations can be adjusted by passing a --prefix argument to configure. Various other options are also supported, pass --help for more information on them.

When complete, make install will place several programs into /usr/local/bin: rustc, the Rust compiler; rustdoc, the API-documentation tool, and rustpkg, 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.
