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.

Polymorphic Associations reversed

It's pretty easy to do polymorphic associations in Rails: A Picture can belong to either a BlogPost or an Article. But what if you need the relationship the other way around? A Picture, a Text and a Video can belong to an Article, and that article can find all media by calling @article.media

This example shows how to create an ArticleElement join model that handles the polymorphic relationship. To add fields that are common to all polymorphic models, add fields to the join model.

Speed up integration tests in Rails 5 app

Rails 5 recompiles templates on every request in test env. Fix will be released only in 5.0.2.

Add this lines to test helper to get the performance now (I've got x2 improvement):

class << ActionView::LookupContext::DetailsKey
 def clear

fallwith

logger.warn "*** BEGIN RAW REQUEST HEADERS ***"
self.request.env.each do |header|
  logger.warn "HEADER KEY: #{header[0]}"
  logger.warn "HEADER VAL: #{header[1]}"
end
logger.warn "*** END RAW REQUEST HEADERS ***"
