= Task Queue (for Kohana php 3)

== Introduction

Task Queue is a task-based queue module for KO3. It was based on the Task_Queue module (a KO2 task queue on a RDBMS datastore) and MangoQueue.

== Requirements

Compiled php with additional ./configure --enable-pcntl

You may also need to install pcntl:
- download php source
  cd /php.../ext/pcntl
  make install

Create a new table:

# Table structure for table 'tasks'

CREATE TABLE /*!32312 IF NOT EXISTS*/ `tasks` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `route` varchar(50) default NULL,
  `uri` text,
  `e` tinyint(1) unsigned NOT NULL default '0',
  `priority` tinyint(2) unsigned default NULL,
  `created` int(11) default NULL,
  PRIMARY KEY  (`id`)

== A Task ased Queue

A php server daemon is run through php cli (command line) that spawns parrallel processes to complete any tasks it finds in the database.

Each task simply consists of a route and uri:

  Request::factory( Route::get( $task->route )->uri( $task->uri ) )->execute();

== Usage: Adding tasks

Adding a task to the queue, is simple:

  task_queue::add_task('route', 'controller', 'action', 'id', $priority);

Of course, the keys of the URI array should match the keys you have specified in the route you’re requesting.

== Executing tasks

When adding a task, you specify what route/controller/action/id should is requested. You have to build the controllers yourself. You can opt to have your controller extend Controller_CLI. This way, the controller will only be accessiible by CLI (and not from the web).

  class Controller_MyQueue extends Controller_Cli {
    	public function action_action1($id)
    		// do something

== Running the queue daemon

After setting some preferences in the daemon config file, running the daemon is simple, from the root command line run:

  php index.php --uri=daemon

or you can start/restart/stop the daemon from any controller:
