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

• rbenv
• ruby-build

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.

  def initialize(elements, satisfied:)
    @elements = elements
    @satisfied = satisfied

# Given an ordered list of elements, how can the possible combinations
# of those elements (of all lengths, order does not matter, no
# repetition) be traversed in the sequence shown below? Either
# iterative or recursive, but it needs to be in such a way that the
# computation of certain branches can be skipped based on a condition
# computed from the combination. E.g. when it reaches [:a, :b], it
# should be possible to say: if check?([:a, :b]) then skip everything
# until [:a, :b, :d] and continue with [:a, :c].
#
# In the concrete problem behind this, the list of elements is a lot

# Problem:
#
# If you use git submodules linking two private github repos, you'll need to create a separate deploy key for each.
# Multiple keys are not supported by Ansible, nor does ansible (when running git module) resort to your `.ssh/config` file.
# This means your ansible playbook will hang in this case.
#
# You can however use the ansible git module to checkout your repo in multiple steps, like this:
#
- hosts: webserver
  vars:

Envek

# Enables PostgreSQL interval datatype support (as ActiveSupport::Duration) in Ruby on Rails 4.1.
# Based on https://gist.github.com/clarkdave/6529610

require 'active_support/duration'

# add a native DB type of :interval
ActiveRecord::ConnectionAdapters::PostgreSQLAdapter::NATIVE_DATABASE_TYPES[:interval] = { name: 'interval' }

# add the interval type to the simplified_type list. because this method is a case statement
# we can't inject anything into it, so we create an alias around it so calls to it will call

Here's what I've (re)learned after a few hours poking at Sequel and ActiveModel::SecurePassword.has_secure_password

It's Even Simpler than I Remember It

In olden times (pre-AM 4.3?) I seem to recall that there were more than one ActiveModel module that needed to be included in a non-ActiveRecord::Base subclass to get it to meet requirements for has_secure_password. That has now been reduced to one (meta-)module.

For example, see the below user.rb file. All you need is include ActiveModel::SecurePassword, apparently.
