'''<span style="color:#f00;">M</span>edia<span style="color:#f00;">W</span>iki''' is a [[:en:free software|free]] Wiki software package licensed under the [[:en:GNU General Public License|GNU General Public License]]. It is used to run [[:en:Wikipedia|<span style="color:#f00;">W</span>iki<span style="color:#f00;">p</span>edia]] and other [[:en:Wikimedia Foundation|<span style="color:#f00;">W</span>iki<span style="color:#f00;">m</span>edia Foundation]] [[wikimedia:Our projects|projects]], as well as [[m:Sites using MediaWiki|many other wikis]]. In case you don't already know, a [[:en:Wiki|wiki]] is a publicly editable website which allows its visitors to collaborate by editing its pages.

== What is a Wiki==
<div style="background-color:#fed569; border:3px double #4b0082; margin:1em; padding:1em; width:auto;">

'''''À vaincre sans péril, on triomphe sans gloire.''''' ([[:fr:Pierre_Corneille|Pierre Corneille 1606-1684]]) {{fr}} [[Image:Corneille.jpg|right|120px|Pierre Corneille (1606-1684)]] <br>''To overcome without danger, one triumphs without glory.'' ([[:en:Pierre_Corneille|Pierre Corneille]]) {{en}}
'''Welcome''' to visitors who are new to the '''[[:en:Wiki|Wiki]]''' concept
and probably came here because they clicked on a '''Powered by MediaWiki''' icon.
You are entering a world of respect and trust.
'''Yes''' : <u>you can</u> modify this page and <u>you can</u> even (temporarily) publish dummy sentences,
and <u>you can</u> even (temporarily) completely [[Talk:MediaWiki|destroy]] the page.
You don't need to be a [[:en:Hacker|hacker]] to do this.
We suggest you rather exercise yourself within another page ([[Sandbox|just click here to reach such a page]])
to avoid other visitors needing to clean up this main page after you.
<br>If you want to share your knowledge about MediaWiki, you may edit this page.
If you have a question or a suggestion, do not edit this page, but, instead, use the [[Talk:MediaWiki|related discussion page]].

== How does MediaWiki work? ==
<div style="background-color:#f9f9f9; width:auto; border:3px double #4b0082; margin:1em; padding:1em;">
[[Image:Wikimedia-servers-2005-04-12.png|thumb|MediaWiki can be used in large enterprise server farms.]]
MediaWiki uses [[:en:PHP|PHP]] to process and display data stored in its [[:en:MySQL|MySQL]] database. Pages use MediaWiki's wikitext format, so that users without knowledge of XHTML or CSS can edit them easily. When a user submits an edit to a page, MediaWiki writes it to the database, but without deleting the previous versions of the page, thus allowing easy reverts in case of vandalism or spamming. MediaWiki can manage image and multimedia files, too, which are stored in the filesystem. For large wikis with lots of users, MediaWiki supports caching and can be easily coupled with Squid.

To install MediaWiki, you will need ''any'' operating system ([[:en:Linux|GNU/Linux]] is suggested), ''any''
web server ([[:en:apache|apache2]] is suggested), PHP >= 4.3 (PHP 4.3.11 is suggested) and MySQL >= 3.23 (MySQL 4.0.23 is suggested). You do not need a specific software to manage MySQL but such tool may help you for backups and other tasks ([[:en:phpMyAdmin|phpMyAdmin]] 2.6.1 is suggested). MediaWiki ships with an installation utility which will enable you to install it using your Web browser. If you do not operate your own server and have only access to one database, mind that MediaWiki is able to share its database with other applications. You don't need to know SQL, HTML, XHTML or CSS. A basic knowledge of PHP is required if you need to modify the configuration files.

* Look and feel can be modified. Read the [[#Skins|skins]] subsection below.
* Extensions and patches are provided by the community. They generally fall into one of these categories&nbsp;:
** Extensions defining a new [[m:Wiki Tag|wiki tag]]

==Important Release Notes==

===Stable releases series 1.4.x===

<div style="border:3px dashed #4b0082; background-color:#f0fff0; padding:1em; margin:1em;">

<span style="color:red;">1.4.7 released 2005-07-16</span>: Stable series bugfix release

[{{download|mediawiki-1.4.7.tar.gz}} mediawiki-1.4.7.tar.gz]

:'''MediaWiki 1.4.7''' is a bug fix release. Those affected by the following problems in 1.4.6 should upgrade:

:* Watchlist breakage on MySQL 3.23.x and with table prefix enabled
:* Possible breakage in watchlist, some image resizing modes on PHP 4.1.2

:<span style="color:red;">1.4.6 included a fix for a cross-site scripting vulnerability, so anyone running older 1.4 releases is very strongly encouraged to upgrade as well.</span>

:Note to upgraders: current versions of MediaWiki are known to produce a large number of notice-level warnings under the newly released PHP 4.4.0. These appear however to be harmless; if you encounter them add this to your LocalSettings.php to suppress the notices:

::<code>error_reporting( E_ALL & ~E_NOTICE );</code>

:PHP 5.1.0beta3 is known to be incompatible at this time.

:'''Changes since last release''': ([http://sourceforge.net/project/shownotes.php?release_id=342530 full release notes])

:* ([[MediaZilla:2755]], [[MediaZilla:2747]]) MySQL 3.23.x and table prefix compatibility fix: restore old watchlist code
:* PHP 4.1.2 compatibility fix: define floatval() equivalent if missing

:MediaWiki 1.5 beta 3 is a preview release of the new 1.5 release series, with a security update over beta 2. Third-party users should probably not use this beta release to run a public site unless paying close attention to development and ongoing releases.

:A number of significant changes have been made since the alpha releases, including database changes and a reworking of the user permissions settings. See the file [http://cvs.sourceforge.net/viewcvs.py/*checkout*/wikipedia/phase3/UPGRADE?rev=1.11 UPGRADE] for details of upgrading and changing your prior configuration settings for the new system.
