Esta é unha vista xeral de alto nivel de desenvolvemento MediaWiki, incluíndo enlaces para os principais documentos, recursos e ferramentas dispoñibles para os desenvolvedores de MediaWiki. Está escrito para desenvolvedores cualificados LAMP que teñen experiencia usando MediaWiki.

Vista xeral

MediaWiki is the software that powers Wikipedia, its sister projects and thousands of wikis all over the world.

MediaWiki is written in the PHP programming language.[1] It uses jQuery as the client JavaScript library.

MediaWiki is primarily written for the LAMP platform[2] and runs on most operating systems. MediaWiki primarily uses the MySQL and MariaDB database servers.[3]

MediaWiki é desenvolvido nun código abertostyle[4] usando a linguaxe de programación PHP [5] sobre todo para a plataforma LAMP[6] [7]. O desenvolvemento do núcleo é en gran parte coordinado liña.

The main developer list is wikitech-l. The main developer IRC channel is #mediawiki connect.

  • Source code is managed using the Git version control system.


  • Bug reports and tasks for most projects are managed on Phabricator .
  • Developers extending or interfacing with MediaWiki (instead of working on the core code) have several convenient extension points, including the API, the Hooks system and Skins – see the #Extending MediaWiki section of this page for an overview.

Depuración e probas

  • Unit testing – learn to write unit tests for MediaWiki using PHPUnit.


  • Manual namespace on this wiki – documentation for developers.
  • MediaWiki Class Reference – technical documentation generated from the MediaWiki source code. (Note: The class reference is a large, slow-to-load page.)


  • API – MediaWiki's API provides direct, high-level access to the data contained in the MediaWiki databases.
  • ContentHandler MediaWiki's framework for supporting custom types of page content.
  • Database access an overview of using databases in MediaWiki, including a brief guide to the database abstraction layer.
  • Job queue MediaWiki's framework for processing long-running tasks asynchronously.
  • Messages API MediaWiki's framework for providing localized application messages with PHP or JavaScript.

Extending MediaWiki

MediaWiki has been designed to allow for modification without changing the "core code". This makes it easy to update to a new version of MediaWiki without having to manually merge in old extension code changes. There are six main extension points that allow developers to change or extend what MediaWiki can do. The extension points are:

  • API – access the data and metadata of MediaWiki instances through its web API.

  1. Not all of MediaWiki is written in PHP. Some supporting tools are written in other languages, including batch files, shell scripts, makefiles and Python.
  2. MediaWiki runs on most platforms that can support PHP, however, the lack of certain utilities or operating system features may limit the functionality or performance of MediaWiki on non-LAMP platforms.
  3. MediaWiki has support for DBMS other than MySQL and MariaDB, including PostgreSQL and SQLite.
  4. Os creadores son unha mestura de voluntarios e funcionarios pagados Fundación Wikimedia (ou contratados). Para unha lista completa de quen traballa co código MediaWiki, lea o artigo Developers
  5. Non todo MediaWiki está escrito en PHP. Algunhas ferramentas de apoio están escritos noutras linguaxes, incluíndo batch files shell scripts, makefiles e Python.
  6. MediaWiki execútase na maioría das plataformas que poden apoiar PHP, con todo, a falta de certos servizos públicos ou recursos do sistema operativo poden limitar a funcionalidade ou funcionamento de MediaWiki en plataformas NO-LAMP.
  7. MediaWiki ten soporte para DBMS exceptoMySQL, incluíndo Oracle, PostgreSQL e SQLite.
  8. Browse the source code and revisions of code repositories in Gerrit or download the source code to your system by using Gerrit .
