Compatibility/pt

MediaWiki strives to maintain broad compatibility between versions, and with a range of current and legacy software. At the same time, the constantly-evolving codebase and features of the latest MediaWiki development mean that it is not possible to maintain compatibility with legacy software indefinitely.

If you wish to suggest a change to what MediaWiki supports, you can file a request for comment on Phabricator.

Software de servidor
Esta secção fornece um resumo do software necessário na servidor para executar o MediaWiki.

PHP
The latest stable branch of MediaWiki runs on any version of PHP  to PHP 7.3. MediaWiki 1.34 requires PHP 7.2.9+.

Base de dados
O MediaWiki é compatível com uma variedade de servidores de base de dados. É recomendado utilizar MySQL ou MariaDB.

Não é recomendado utilizar qualquer outro software de base de dados. O suporte difere de uma versão do MediaWiki para outra e varia entre duvidoso até estável. O MediaWiki fornece camadas de abstração da base de dados para PostgreSQL e SQLite, que geralmente são bem mantidas.

Servidor da Web
O MediaWiki é amplamente compatível com todos os principais servidores da Web que podem invocar uma versão compatível do PHP. Apache é a mais utilizada e testada. Nginx também é uma boa escolha.

Extensões do MediaWiki
As long as an extension is properly maintained (which you can see at the top of the infobox on its description page), the master branch of the extension should be compatible with the master branch of MediaWiki. For determining compatibility with older MediaWiki versions, there are two common policies used by extensions:


 * master (key: master): the master branch of the extension is compatible with both current and older versions of MediaWiki. Back-compatibility hacks are added to the extension source code as needed.
 * release branches (key: rel): For every MediaWiki release, there is a corresponding branch in the extension. So e.g. if you use MediaWiki, you should use the branch of the extension.

The  field of the Extension infobox tells which policy is used by a given extension. Use the respective keys indicated above to specify the information.

Algumas extensões poderão ter mais políticas especificas de compatibilidade, por exemplo:

Informação geral
There is an ever-growing number of different web browsers in the world.

Too many to actively test and support each one. To guide our practices around browser support, we have three levels of support. Each tier represents a different category of browsers.

Moderno (Grade A)
This group (also known as Grade A) represents the highest level of support. Features take 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 (listed below) and actively tested against. Problems users perceive in these browsers are addressed with high priority.

Básico (Grade C)
The group (also known as Grade C) is provided 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 by 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, but these browsers do not get JavaScript features.

Browsers in this category are known (listed below) and identified via a feature test suite and a blacklist in the startup module.

Desconhecido (Grade X)
This group (also known as Grade X) represents all other browsers. This includes browsers that are no longer developed or browsers not popular enough to justify the added maintenance cost for software development.

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

Problems users perceive in these browsers only are given low priority, or not supported at all.

MediaWiki handles these browsers the same as Modern (Grade A) browsers and they are thus assumed to be capable. This principle provides various important benefits:


 * New or unsupported versions of modern browsers may temporarily be considered Unknown if they are not yet tested against by us. Treating Unknown browsers as capable ensures optimal user experience in these browsers.
 * Users of new and evolving browsers are given a chance to have a modern experience.
 * Users of less popular browsers based on, or derived from, known modern browsers are not negatively impacted (e.g. Iceweasel).

In practice the only difference between Unknown and Modern browsers is that we don't actively test against Unknown browsers.

Estes navegadores recebem o conjunto completo de funcionalidades. In particular, JavaScript will be disabled if no support for features MediaWiki uses is found.

Matriz de suporte do navegador
The principles and different grades described above apply to MediaWiki core and extensions alike. The support matrix below applies these grades in the context of MediaWiki core, Wikimedia Foundation infrastructure, and any MediaWiki extensions that decide to follow it. Individual extensions may have their own support matrix distributing browsers among the different levels of support. See also Browser usage breakdown dashboard.

(Última atualização: outubro de 2019) (em inglês)

Dispositivo Móvel
A equipa da Web na Fundação Wikimedia utiliza uma matriz de suporte um pouco diferente para temas específicos para os dispositivos móveis por exemplo e/ou extensões projetadas para serem executadas nos dispositivos móveis por exemplo. The support matrix is compiled from the data provided by the analytics user agent breakdown dashboard. Where browser usage is over 5% a modern experience (Grade A) is supported. Basic support (Grade C) is provided for anything over 0.1% over the 12 months. In mobile we strive to provide a Grade B. Users of grade B may or may not get JavaScript and we do not test to the same level as A, thus we prioritize bug fixes lower.

Grade A browser list on MobileFrontend is defined in .browserlistsrc file.

Anything absent in the list or older is considered a Grade C browser.
