Este artículo está escrito para ayudar a desarrolladores novatos para que aprendan las habilidades necesarias para contribuir al desarrollo de MediaWiki y sus extensiones. En la mayoría de los casos cuando trabajas con MediaWiki, tu no querras modificar MediaWiki a menos que sepas realmente bien lo que está haciendo.

The main path to get started with Wikimedia development is to contribute to Wikimedia projects that offer mentoring. An alternative without mentoring is to fix a good first bug.

Si eres un desarrollador experimentado que posee experiencia con MediaWiki, visita el Centro del desarrollador en cambio.

Resumen

MediaWiki es el software que permite el funcionamiento de Wikipedia, sus proyectos hermanos y miles de wikis en todo el mundo.

MediaWiki está escrito en el lenguaje de programación PHP[1]. Usa jQuery como librería cliente de Javascript.

MediaWiki está escrito principalmente para la plataforma LAMP[2] y se ejecuta en la mayoría de los sistemas operativos. MediaWiki usa principalmente servidores de MySQL y MariaDB.[3]

Development happens in an open source style[4], is largely coordinated online, and supported by the Wikimedia Foundation, though volunteer community developers play a huge part as well.

Esta página debería ayudarte a convertirte en un colaborador de MediaWiki. No es un tutorial; justo te señalas a varios sitios donde te puede ir aprender cualquier cosa es necesaria.

Instalando tu ambiente de desarrollo

La mayoría de los proyectos usan Git y Gerrit. Sigue el tutorial de Gerrit para crear tu cuenta de desarrollador. Then you can move on to downloading our code, making changes, testing them, and submitting patches.

Hay dos maneras para instalar vuestro entorno de desarrollo: utilizando un pre-máquina virtual configurada setup (vagrant), o manual.

Máquina virtual con Vagrant

  • Instalación de Vagrant - Esto da un paso que instalará el servidor de MediaWiki con todos los requisitos dentro de una máquina virtual con Linux (puede ser utilizado en Linux, Windows, o Hosts de Mac)

Docker development environment

Instalación manual

No es necesario descargar vertederos de base de datos de Wikipedia para desarrollar las características de MediaWiki. De hecho, en muchos casos es más fácil de utilizar una cercana-base de datos vacía con unos cuantas páginas de pruebas especiales. Aun así, si para alguna razón quieres tener una copia de Wikipedia, puedes conseguir un vertedero.

Lectura sugerida

Watch as a developer fixes a bug in a MediaWiki extension, including investigation, git commit, getting it reviewed and merged, and closing the Bugzilla ticket (now replaced by Phabricator ).

Comentarios, preguntas y asistencia

  • You are expected to do some basic research yourself first: Look at the code, try to get some understanding what it is supposed to do, read related documentation, try to find the probable place(s) where you need to make changes in order to fix the bug.
  • If you have general questions which are not tied to the specific task that you want to work on, use generic channels like Wikimedia Developer Support, IRC or mailing lists but not the specific task.
  • If you have a specific question about the bug itself, comment in the corresponding bug report (normally a task in Phabricator ). "Can you give me more info how to fix this bug?" is not a good question to start with: The more specific your questions are, the more likely somebody can answer them quickly. If you have no idea at all how to fix the bug, maybe that bug is not (yet) for you - please consider finding an easier one first.
  • When asking, explain what you have tried and found out already, so others can help at the right level. Be specific - for example, copy and paste your commands and their output (if not too long) instead of paraphrasing in your own words. Esto evita malentendidos.
  • Avoid private email or support requests in our social media channels.
  • Be patient when seeking input and comments. On IRC, don't ask to ask, just ask: most questions can be answered by other community members too if you ask on an IRC channel. If nobody answers, please ask on the bug report or wiki page related to the problem; don't just give up.
  • Más información en Comunicación .
  • Puedes realizar cualquier pregunta en la reunión semanal de asistencia en el canal #wikimedia-tech de IRC en Freenode.



Comunicar que trabajas en una tarea

Do not ask if you can work on a task. You do not need to announce your plans before you start working on a bug, but it would be welcome. You are welcome to set yourself as the assignee in a task: Use the dropdown Add Action… → Assign/Claim in Phabricator. At the latest when you are close to proposing a patch for the task, it is good to announce in a comment that you are working on it. Your announcement helps others to not work on the bug at the same time and to not duplicate work.

Also note that if a task already has a recent link to a patch in Gerrit and has the project "Patch-For-Review" associated in Phabricator, choose a different task to work on instead - avoid duplicating work. If an existing patch in Gerrit has not been merged and has not seen any changes for a long time, you could also pick up that existing patch and improve it, based on the feedback in Gerrit and in the task.

If you stop working on a task, remove yourself as the assignee of the task, so others know that they can work on the task and don't expect you to still work on it.

By communicating early you will get more attention, feedback and help from community members.

PHP

MediaWiki is written in PHP, so you'll need to get familiar with PHP to hack MediaWiki's core.

Aprende PHP
  • Tutorial de PHP — Disponible en muchos idiomas diferentes. If you have no knowledge of PHP but know how to program in other object-oriented programming languages, PHP will be easy for you to learn.
  • PHP Programming at Wikibooks.
  • PHP topic at Wikiversity.
Recursos de PHP
Stuff to know
  • The script maintenance/eval.php in MediaWiki provides a basic PHP interpreter with MediaWiki objects and classes loaded.
  • Also, the script maintenance/shell.php in MediaWiki is a replacement of maintenance/eval.php based on PsySH, see Manual:Shell.php.


Base de datos

Many features require some amount of database manipulation, so you'll often need to be familiar with MySQL/MariaDB.

Aprende MySQL/MariaDB
Recursos de MySQL/MariaDB
Stuff to know
  • Test your code with MySQL/MariaDB.
    • MediaWiki currently uses MySQL and MariaDB as the primary database back-end. It also supports other DBMSes, such as PostgreSQL and SQLite. However, almost all developers use MySQL/MariaDB and don't test other DBs, which consequently break on a regular basis. You're therefore advised to use MySQL/MariaDB when testing patches, unless you're specifically trying to improve support for another DB. In the latter case, make sure you're careful not to break MySQL/MariaDB (or write queries that are horribly inefficient in it), since MySQL/MariaDB is what everybody else uses.

JavaScript y CSS

JavaScript and CSS have become omnipresent in front-end code. You don't have to be familiar with JavaScript, jQuery and CSS to work on MediaWiki, but you might need to, depending on what you choose to work on.

MediaWiki

The MediaWiki code base is large and some parts are ugly; don't be overwhelmed by it. When you're first starting off, aim to write features or fix bugs which only touch a small region of code.

  2. ↑ MediaWiki puede ejecutarse en la mayorías de las plataformas que soportan PHP, sin embargo, la falta de algunos programas utilitarios o características del sistema operativo pueden limitar la funcionalidad o rendimiento de MediaWiki en plataformas que no son LAMP.
  3. ↑ MediaWiki posee soporte para más gestores de bases de datos, incluyendo a Oracle, PostgreSQL, SQLite y Microsoft SQL Server.
