ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

I'm a fan of MiniTest::Spec. It strikes a nice balance between the simplicity of TestUnit and the readable syntax of RSpec. When I first switched from RSpec to MiniTest::Spec, one thing I was worried I would miss was the ability to add matchers. (A note in terminology: "matchers" in MiniTest::Spec refer to something completely different than "matchers" in RSpec. I won't get into it, but from now on, let's use the proper term: "expectations").

Understanding MiniTest::Expectations

Let's take a look in the code (I'm specifically referring to the gem, not the standard library that's built into Ruby 1.9):

# minitest/spec.rb

module MiniTest::Expectations

These are instructions to setup Postgres.app to allow connections over unix sockets. These instructions were written for Mac OS X 10.8 (Mountain Lion).

Run Postgres.app once so that the configuration is initialized in ~/Library/Application Support/Postgres.
Close Postgres.app
Open ~/Library/Application Support/Postgres/var/postgresql.conf in your favorite text editor.
Uncomment the line unix_socket_directory = '' and change it to unix_socket_directory = '/var/pgsql_socket'
Create the directory /var/pgsql_socket if it doesn't exist.
Run chmod 770 /var/pgsql_socket (may need to be run with sudo)
Run chown root:staff /var/pgsql_socket (may need to be run with sudo)
