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.

Subdomains in Rails 3

Are still a nightmare to get tested, etc.

To share sessions across subdomains you need to set the session options during the request so you know what domain you're sharing across. This means we still need to do it with a before_filter, or something similar. It looks like you should be able to set :domain => true in config/initializers/session_store.rb to do this instead but Devise does not support it yet as far as I can see.

Here I'm using subdomains with a custom url_for extension which means from "http://www.smackaho.st" root_path would be "/" while from "http://admin.smackaho.st" root_path would be "http://www.smackaho.st/".

In cucumber this is forced to always qualify the full URL with the subdomain. It also rewrites the port in/out as neccessary to cope with Capybara's server using an alternate port (used by Selenium for javascript testing etc). The project I'm on is still using web_steps (sigh) so I had to touch the "should be on" step definition to cope with

Proposal for Improving Mass Assignment

For a while, I have felt that the following is the correct way to improve the mass assignment problem without increasing the burden on new users. Now that the problem with the Rails default has been brought up again, it's a good time to revisit it.

Sign Allowed Fields

When creating a form with form_for, include a signed token including all of the fields that were created at form creation time. Only these fields are allowed.

To allow new known fields to be added via JS, we could add:

dhh

class PostsController < ActionController::Base
  def create
    Post.create(post_params)
  end
  
  def update
    Post.find(params[:id]).update_attributes!(post_params)
  end
