Compatibility/zh

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.

浏览器
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.

现代
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.

基本
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.

Browsers in this category are known (listed below) and identified via a blacklist in the startup module. Problems users perceive in these browsers are addressed with high priority. Issue handling focuses 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.

MediaWiki may serve these browsers a JavaScript-less 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.

未知
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.

MediaWiki handles these browsers the same as Modern (Grade A) browsers and are thus assumed to be capable. This principle provides various important benefits:
 * New 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. These browsers are given the full feature set.

浏览器支持矩阵
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.


 * 个别手机浏览器会包括在此. 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
MediaWiki的最新稳定分支（）可运行在PHP 到PHP 7之间的版本. 这里还有实验中的HHVM支持.

MediaWiki 1.23 and 1.26 will continue to receive security updates until their respective end-of-life dates (see version lifecycle) and retain compatibility with their respective versions of PHP.

数据库
MediaWiki兼容不同种类的数据库服务器，尽管MySQL支持度最好. （MariaDB也可以用了）

Support for any other database software ranges from dubious to stable; architectures for which have at least some support. Running MediaWiki on anything other than MySQL or MariaDB is not recommended for production use at this point.

Web服务器
MediaWiki is broadly compatible with all major web servers that can invoke a compatible version of PHP. Apache is the most used and tested.

 * Software marked in blue is supported while software marked in orange is not supported.
