README

This project is no longer maintained. A Symfony2 bundle that makes it easy to configure and deploy your app on Pagoda Box.

####Features

Focus on high-performance
- Never use shared writable directories for Symfony's cache (why?)
- Store PHP sessions in Redis (why?)
Easily configure Doctrine connection parameters with no extra setup
Easily configure Doctrine to utilize Pagoda Box caches
Full composer support
- Don't check in your vendor directory! This bundle installs your dependencies during the build on Pagoda Box.
- Optionally utilize a GitHub OAuth token to prevent timeouts
Excellent test coverage - ready for production

###Requirements

Symfony 2.3+

###Installation Add to your composer.json:

"require": {
   "ehough/pagodabox-bundle": "dev-master"
}

Then register the bundle in app/AppKernel.php:

public function registerBundles()
{
    return array(

        // ...
        new Ehough\Bundle\PagodaBoxBundle\EhoughPagodaBoxBundle()
    );
}

###Feature: Easy Application Deployment

Perhaps the most valuable feature of this bundle is the ability to properly deploy a composer-based Symfony2 app to Pagoda Box. Simply add the following two after_build steps:

#####Boxfile

web1:

  shared_writable_dirs:
    -<relative path to your Symfony app root>/app/logs    # notice: no app/cache directory!

  after_build:
    - curl -Lso ./gopagoda.sh https://raw.github.com/ehough/EhoughPagodaBoxBundle/master/Resources/bash/gopagoda.sh; sed -i -e 's/\r//' gopagoda.sh;
    - bash ./gopagoda.sh <relative path to your Symfony app root> <optional GitHub OAuth token>

The two after_build steps above effectively download and execute gopagoda.sh, which will do the following on your behalf:

Download composer.phar from getcomposer.org.
If you supplied a GitHub OAuth token, configure composer to utilize it.
Install your app's dependencies (composer install)
Create an optimized classloader for maximum classloading peformance (composer dump-autoload --optimize)
Build any assetic assets (app/console" "assetic:dump" --env=prod)
Clear any leftover Symfony cache (app/console" "cache:clear" --env=prod)
Warm the Symfony cache (app/console" "cache:warmup" --env=prod)
Trigger an initial HTTP request to Symfony to finish warming the cache (php web/app.php)

This will fully prepare your Symfony2 app for production before it's deployed to its final web server. Notice that we are not using the app/cache directory for shared writable storage. Neat!

###Feature: Redis Session Storage Pagoda Box strongly recommends that you utilize a Redis cache for session storage. This bundle makes this task as easy as possible.

#####Boxfile

web1:

  php_extensions:
    -redis

  php_session_save_handler: redis
  php_session_save_path: "tcp://tunnel.pagodabox.com:6379"

#####app/config_prod.yml

ehough_pagoda_box:

  store_sessions_in_redis: true

That's it! Your Symony sessions will now magically be stored safely in Redis.

###Feature: Better Annotations Caching By default, Symfony will use a file-based cache for its annotations cache. With this bundle we can easily utilize a Pagoda Box cache instead.

#####Boxfile

web1:

  php_extensions: # at least one of these
    -memcache
    -memcached

#####app/config_prod.yml

ehough_pagoda_box:

  annotations_cache:
    type: memcached         # memcache or memcached
    pagoda_env_id: CACHE2   # the Pagoda Box cache ID you'd like to use for the annotations cache

The type parameter can have a value of memcache, memcached, or redis, depending on the actual type of the cache you identify in the pagoda_env_id parameter.

###Feature: Easier Doctrine Connection Configuration Pagoda Box provides instructions on how to configure your Symfony database for their platform. However, this bundle makes the process much easier.

#####app/config_prod.yml

ehough_pagoda_box:
  doctrine:
    dbal:
      connections:
        default:
          pagoda_env_id : DB1
          platform_class: Doctrine\DBAL\Platforms\MySqlPlatform

As you can see in the above app/config_prod.yml, you define a map of Doctrine DBAL connection identifiers to their corresponding Pagoda Box databases. In the example above, we are mapping the default DBAL connection to DB1. i.e. The default connection will receive the values of the environment variables DB1_HOST, DB1_PORT, etc.

It's also necessary to specify a platform_class for each connection. This should be the class name that represents the underlying DB connection, and should be a class that extends \Doctrine\DBAL\Platforms\AbstractPlatform. This step is necessary so that \Symfony\Bridge\Doctrine\CacheWarmer\ProxyCacheWarmer can do its job without having to contact the database (which we don't yet have access to). Since Pagoda Box currently only supports MySQL, you will always set platform_class to Doctrine\DBAL\Platforms\MySqlPlatform.

In most cases, you will simply need to configure the default DBAL connection, but you can define as many connection mappings as you like. e.g.

ehough_pagoda_box:
  doctrine:
    dbal:
      connections:
        default:
          pagoda_env_id : DB1
          platform_class: Doctrine\DBAL\Platforms\MySqlPlatform
        other:
          pagoda_env_id: DB2
          platform_class: Doctrine\DBAL\Platforms\MySqlPlatform
        another:
          pagoda_env_id: DB3
          platform_class: Doctrine\DBAL\Platforms\MySqlPlatform

###Feature: Easier Doctrine Cache Configuration Out of the box, Symfony provides in-memory caches for Doctrine's query, result, and metadata caches. With this bundle, we can easily configure Doctrine to utilize any number of Pagoda Box memcached instances instead.

#####Boxfile

web1:

  php_extensions: # at least one of these
    -redis
    -memcache
    -memcached

#####app/config_prod.yml

ehough_pagoda_box:
  doctrine:
	orm:
	  caching:                      # a map of Doctrine ORM entity manager IDs to
	    default:
		  metadata:                 # metadata, query, or result
		    type: memcache          # memcache or memcached
      		pagoda_env_id: CACHE3 	# the Pagoda Box cache ID. This must be a Memcache cache!
          query:
            type: memcache
            pagoda_env_id: CACHE4
          result:
            type: memcache
            pagoda_env_id: CACHE5

In the example above, we are configuring the default entity manager's metadata, query, and result cache. Each cache accepts a type (memcache or memcached) as well as the Pagoda Box memcached instance identifier.
