What Diem needs to run properly

Diem 5.0 is based on symfony 1.4 and Zend Framework 1.9.
It will only run on a Unix server with apache2 & PHP >= 5.2.4 or php 5.3.x


Configuration Required Info
Server Unix Windows server is not tested yet and will probably not work
PHP version >= 5.2.4 PHP 5.3 is now tested, and it works
PHP C.L.I. ON A php command line interface is required during installation and maintenance of the project
memory_limit >= 48Mo Diem front pages require less than 16Mb. But sometime, when an administrator performs modifications, Diem needs more memory. Page synchronization, search index update and image resizing may require 48Mo
pdo_mysql or pdo_pgsql or pdo_sqlite ON Diem supports MySQL, PostGreSQL and SQLite
json >= 1.0 json_encode is used to communicate with JavaScript
gd ON GD is heavily used to resize front images and provide admin graphs
Configuration Recommended Info
APC ON Diem will use APC if present to store all kind of cache, and dramatically improve performances. If APC is not available, file cache will be used instead
graphviz ON if graphviz is installed on your server, Diem will be able to generate dependence and database diagrams
upload_max_filesize >= 2Mo
mbstring ON
magic quote gpc OFF
register_globals OFF
session.auto_start OFF
pcre ON Used by Zend_Search_Lucene
token_get_all ON
A modern browser Firefox >= 3, Safari 4, Opera >= 9, Google Chrome Administrator interface is not yet tested with poor browsers like IE, and will probably not work
PHP != 5.2.9 PHP 5.2.9 broke array_unique() and sfToolkit::arrayDeepMerge(). Use 5.2.10 instead [Ticket #6211]
