Description Author

This package can manage the execution of multiple parallel tasks.

It provides an event-driven, preemptive Multitasking runtime environment and service management system integrated with Zend Framework 3.

It can start and manage parallel processes using the pcntl extension to fork processes and communicate with them.

The package can also manage the communication of messages between processes.

To guarantee true parallelism and resource isolation ZEUS employs preemptive schedulers and an Inter-Process Communication mechanism to allow its processes to share the data.

The package is shipped with the HTTP Web server and Memcached service written in pure PHP.

Introduction

ZEUS for PHP logo

ZEUS for PHP is an event-driven, preemptive _Multitasking Runtime Environment_ and _Service Management System_ integrated with Zend Framework 3. It's main purpose is to perform multiple tasks (processes) concurrently.

To guarantee true parallelism and resource isolation ZEUS employs preemptive schedulers and an Inter-Process Communication mechanism to allow its processes to share the data.

*ZEUS for PHP is not a standalone service, in order to use it, it must be installed as a module on-top of any Zend Framework application!.*

It's designed to be compliant with any ZF3 application such as Apigility or ZendSkeletonApplication. Custom applications must provide index.php file such as this which instantiates the Zend Framework MVC Zend\Mvc\Application class.

ZEUS for PHP overview

Features

  • Preemptive schedulers allowing to run multiple services asynchronously
  • Built-in IPC server with various IPC Adapters suitable for different Operating Systems or usage characteristics
  • Server service manager allowing to start, stop and track the status of ZEUS server services
  • Well defined, extensive Server Service life-cycle based on Zend Framework EventManager functionality and events such as SchedulerEvent and ManagerEvent
  • Possibility to write your own asynchronous Server Services by using just few lines of boilerplate code
  • Advanced status reporting tools tracking the life-cycle and usage statistics of each service and its processes
  • Deep integration with Zend Framework 3+ and its services such as EventManager and ServiceManager
  • Plugin support allowing to extend functionality of ZEUS Schedulers and Server Services

  • Can be integrated with any Zend Framework 3 Application with just few commands issued in a terminal
  • Compatible with Zend Framework MVC module, enabling ZEUS to dispatch HTTP requests both for static files as well as any Zend Framework Application controller
  • Equipped with its own, customizable Memcached Server Service that is integrated with Zend Framework 3 Cache module, allowing to use any of its Cache adapters as a Memcached key storage
  • Compatible with any UNIX/Linux/BSD platform
  • Well documented and unit tested (with at least 90% code coverage)

Sample usage

Supported command line options

Since version 1.3.5, the following commands are supported (assuming that Zend Framework's index.php application bootstrap file is compatible with Zend Framework 3 MVC Module):

  • index.php zeus start - Starts all ZEUS Server Services
  • index.php zeus start <service-name> - Starts selected Server Service
  • index.php zeus list - Lists all Server Services and their configuration
  • index.php zeus list <service-name> - Shows the configuration of a selected Server Service
  • index.php zeus status - Returns current status of all Server Services
  • index.php zeus status <service-name> - Returns current status of the selected Server Service
  • index.php zeus stop - Stops all ZEUS Server Services
  • index.php zeus stop <service-name> - Stops selected Server Service

Executing functions asynchronously in ZF3 controllers

First, the Async Server Service must be launched in order to execute anonymous functions.

Command:

user@host:/var/www/zf-application/public$ php index.php zeus start zeus_async

The following ZF3 Application code can be handled by any HTTP Server, such as Apache HTTPD or Nginx - such functions are serialized and send to Async Server Service for asynchronous execution.

<?php 
// contents of "zf3-application-directory/module/SomeModule/src/Controller/SomeController.php" file:

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use ZF\Apigility\Admin\Module as AdminModule;

class IndexController extends AbstractActionController
{
    public function indexAction()
    {
        for ($i = 0; $i < 12; $i++) {
            // each run() command immediately starts one task in the background and returns a handle ID
            $handles[$i] = $this->async()->run(function () use ($i) {
                sleep($i);
                return "OK $i";
            });
        }

        // join() accepts either an array of handle IDs or a single handle ID (without array)
        // - in case of array of handles, join will return an array of results,
        // - in case of a single handler, join will return a single result (not wrapped into the array)
        $results = $this->async()->join($handles);

        // because of the sleep(11) executed in a last callback, join() command will wait up to 11 seconds to fetch
        // results from all the handles, on success $result variable will contain the following data:
        // ["OK0","OK1","OK2","OK3","OK4","OK5","OK6","OK7","OK8","OK9","OK10","OK11"]

        // please keep in mind that each handle can be joined independently and join() blocks until the slowest
        // callback returns the data, therefore running $this->async()->join($handles[3]) command instead
        // would block this controller only for 3 seconds

        // usual Zend Framework stuff to return data to the view layer
        $view = new ViewModel();
        $view->setVariable('async_results', $results);
    }
}

Building HTML documentation

Please note, mkdocs must be installed first using the apt-get command, or any other OS-specific package-manager.

Command:

user@host:/var/www/zf-application/vendor/zeus-server/zf3-server$ make doc-server

Serving markdown documentation

Command:

user@host:/var/www/zf-application/vendor/zeus-server/zf3-server$ make doc-build

After executing above command, ZEUS documentation can be found under the following URL: http://127.0.0.1:8080/

Performance

Most of the ZEUS code was heavily optimized and thoroughly tested for speed and efficiency.

As the response times of most of ZEUS services dropped below 1 milisecond, its common for ZEUS to handle more than 24,000 requests/second on an average mobile Intel Core i7 processor:

Requirements

OS requirements

  • Linux/Unix/BSD platform
  • _Windows platform currently not supported_

PHP requirements

  • PHP 5.6+ (HHVM or PHP 7+ is recommended for performance reasons as ZEUS can be up to 4x faster and use less memory)
  • Posix module installed and enabled
  • Pcntl module installed and enabled
  • socket functions enabled for IPC purposes

Library requirements

  • Zend Framework 3+ application (with the following modules installed: zend-mvc, zend-mvc-console, zend-console, zend-log, zend-config)
  • Opis library (opis/closure)

Installation

ZEUS for PHP can be installed in two different ways:

Downloading

via Composer:

user@host:/var/www/$ cd zf3-application-directory
user@host:/var/www/zf3-application-directory$ composer require zeus-server/zf3-server

by downloading source code

Source codes can be found in ZIP file under the following URL: https://github.com/artur-graniszewski/ZEUS-for-PHP/archive/master.zip

After downloading, contents of the compressed ZEUS-for-PHP-master directory in ZIP file must be unpacked into a ZF3 zf3-application-directory/module/Zeus directory.

Enabling ZEUS module

After installation, ZEUS for PHP must be activated in Zend Framework's config/modules.config.php file, like so:

<?php 
// contents of "zf3-application-directory/config/modules.config.php" file:

return [
    'Zend\\Log',
    'Zend\\Mvc\\Console',
    '...',
    'Zeus' // this line should be added
];

This can be achieved either by modifying configuration file in any text editor, or by issuing sed command in Application's root directory:

user@host:/var/www/zf3-application-directory$ sed -i "s/'Zend\\\Log',/'Zend\\\Log','Zeus',/g" config/modules.config.php

If ZEUS for PHP is installed correctly, the following terminal command will show ZEUS version and its services in console:

user@host:/var/www/zf-application/public$ php index.php zeus status zeus_httpd
