Compatibility/es

MediaWiki se esfuerza por mantener una amplia compatibilidad entre versiones, y con una diversidad de software actual y antiguo. Al mismo tiempo, la base de código y las características en continua evolución de los últimos desarrollos de MediaWiki significan que no es posible mantener la compatibilidad con software antiguo de forma indefinida.

Navegadores
This describes our practices around browser support.

Grade C
The base level support provides the core functionality of the MediaWiki platform. Our HTTP responses are compatible with these browsers (e.g. HTTP features we rely on, character encoding, and image formats used in the content; must work in these browsers). In the front-end this means content is presented in a readable manner, and to some extent user actions can be performed.

Browsers in this category are known and identified via a blacklist in the startup module.

The software provides these browsers a javascriptless environment. The environment may lack certain visual features and extra functionally. The core functionality for these browsers must be maintained via traditional client-server interaction with full GET/POST page loads. Problems users perceive in these browsers are addressed with high priority. Issue handling focusses mainly on ensuring provided functionality is not broken; if acceptable from a product perspective, this may result in the functionality (whether or not temporarily) no longer being provided for these browsers.

Grade A
This level represents the highest level of support. It takes advantage of capabilities in modern browsers, while allowing a graceful fallback for older browsers. All features provided by the software (whether or not in a degraded form) must work in these browsers.

Browsers in this category are known and actively tested against. Problems users perceive in these browsers are addressed with high priority.

Grade X
This level represents all other browsers. This includes browsers that are no longer developed or browsers not popular enough to justify the added maintenance overhead.

Browsers not included in any other grade belong to this category.

Tratamiento
The software treats these browsers the same as Grade A browsers and are thus assumed to be capable. This principle provides various important benefits:
 * Newly released versions of Grade A browsers may unexpectedly be considered Grade X if they are not yet tested against.
 * Users of upcoming browsers are given a chance to have a Grade A experience.
 * Users of less popular browsers based on or derived from browsers with the same capabilities are not negatively impacted (e.g. Iceweasel).

In practice the only difference between Grade X and Grade A browsers is that we don't actively test against Grade X browsers. And problems users perceive in these browsers only are not prioritised.

Matriz de soporte de navegadores
While the principles and different grades described above apply to MediaWiki core and extensions alike, the below browser support matrix applies to MediaWiki core only (and extensions that decide to follow it). Individual extensions may have their own support matrix distributing browsers among the different levels of support differently.
 * A few mobile browsers are included here. However as noted earlier, this matrix is for MediaWiki core and its desktop skin. Mobile-specific skins and/or extensions especially for mobile devices may have a different support matrix.

PHP
La última versión de MediaWiki funciona con cualquier versión de PHP desde hasta PHP 5.5. En este momento, HHVM tiene cuestiones sin resolver y podría provocar que algunas características dejen de funcionar.

Las últimas versiones de MediaWiki contienen características que no están soportadas por PHP 5.0, 5.1 y 5.2; si se intenta ejecutar con esas versiones, fallará.

Base de datos
MediaWiki es compatible con varios servidores de bases de datos, pero la más soportada es MySQL. (También se puede usar MariaDB).

El soporte para otro software de bases de datos oscila entre dudoso y estable; las arquitecturas para las cuales tienen al menos algún soporte. Cualquier otra cosa que no sea MySQL o MariaDB no se recomienda para un uso de producción en este momento.

Servidor web
MediaWiki es ampliamente compatible con los principales servidores web que puedan ejecutar PHP. Apache es el más usado y probado. Siempre que la versión del servidor soporte la versión necesaria de PHP de acuerdo con la matriz que se muestra aquí.

Notas

 * Software marked in green is supported while software marked in red is not supported.
