Netresearch distributed lock manager

====================================

.. contents:: Contents

Overview

========

NR_Lock is a distributed lock manager (DLM).

This is designed for multiple TYPO3 frontend servers using a single typo3temp

share and Database.

NR_Lock currently supports single Redis or Couchbase (experimental) caching

server as locking instance.

It replaces/extends the TYPO3 lock facility t3lib_lock.

Requirements

============

- Redis: => 2.4 - 2.8

- Couchbase: => ???

- PHP => 5.3 - 5.5

- TYPO3 => 4.5 - 6.2

- PHP/redis => 1.6

Installation

============

Installation is done by TYPO3 extension manager.

Configuration

=============

To set up NR_Lock as a replacement for t3lib_lock you need to alter your

localconf.php in /typo3conf/ and add the following lines::

    $arLockCfg = &$TYPO3_CONF_VARS['SYS']['locking'];

    if (extension_loaded('redis')) {

        $arLockCfg = array(

            'backend' => '\Netresearch\Lock\Backend_Redis',

            'options' => array(

                //'hostname'         => 'localhost',

                //'port'             => 6379,

                //'database'         => 0,

                //'password'         => '',

                //'compression'      => false,

                //'compressionLevel' => 1,

            ),

        );

    } elseif (extension_loaded('couchbase')) {

        $arLockCfg = array(

            'backend' => '\Netresearch\Lock\Backend_Couchbase',

            'options' => array(

                'servers' => array(

                    'localhost',

                ),

            ),

        );

    }

ToDo

====

- Support multiple caching server.

- Test using LIST for locks with redis (performance).

- Use nr_lock in TYPO3 6.2 ClassLoader - this is currently hard coded in the TYPO3 core
