bors 0a1fcadc90 auto merge of #4958 : cpeterso/rust/reseed-rng, r=graydon 
For Issue #4709:

**c531506 rt: rand.rs expects `rust_next()` to return `uint32_t`, not `size_t`**

rand.rs expects `rustrt::rand_next()` to return `u32`, but the `rand_next()` C function returns `size_t`: ca71c6ec5b/src/libcore/rand.rs (L34)

**f4320b6 move isaac RNG utility functions to new rust_rng.cpp file**
**665e900 encapsulate isaac RNG in `rust_rng` struct**

Move isaac's `randctx` into a `rust_rng` struct to make names similar to `rand::Rng` function names and prepare for auto-reseeding in the next commit.

**9a78dc9 reseed `rust_rng` after generating 32KB**

Precedents from other languages:
* Haskell's `GenAutoReseed` generator reseeds itself after generating 32KB: http://hackage.haskell.org/packages/archive/DRBG/0.1.2/doc/html/Crypto-Random-DRBG.html#t:GenAutoReseed

* Go's RNG reseeds itself after generating 1MB: https://code.google.com/p/go/source/browse/src/pkg/crypto/rand/rand_unix.go?name=go1.0.3#94

**9a76d71 don't deplete RNG entropy when there is only one runnable task**

`rust_sched_loop::schedule_task()` unnecessarily calls `isaac_rand()` for the common case when there is only 1 runnable task, thus depleting RNG entropy and incurring unnecessary overhead.

The Rust Programming Language

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

Installation

The Rust compiler currently must be built from a tarball, unless you are on Windows, in which case using the installer is recommended.

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.

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.

To build from source you will also need the following prerequisite packages:

  • 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

Assuming you're on a relatively modern *nix system and have met the prerequisites, something along these lines should work.

$ curl -O http://static.rust-lang.org/dist/rust-0.5.tar.gz
$ tar -xzf rust-0.5.tar.gz
$ cd rust-0.5
$ ./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 cargo, the Rust package manager.
