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. 这里描述了我们对浏览器支持的看法. Each tier represents a different category of browsers.

现代
这是最高级别的支持. 此级别充分利用了现代浏览器的各种能力，并允许给旧版浏览器一个优雅的反馈. 所有的特性由软件提供(whether or not in a degraded form)，都必须能在这些浏览器正常工作.

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.

剩下还没分出级别的浏览器便属于这个级别. 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. 然而就像先前注释的那样，这个矩阵适用于MediaWiki核心代码及其桌面端皮肤.

Browser support matrix (mobile)
(Last updated: March 2017)

Mobile-specific skins e.g. Minerva skin provided by MobileFrontend and/or extensions designed to run on mobile devices have a different support matrix. 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 is supported. Basic support is provided for anything over 0.1% over the 12 months. In mobile a Grade B is maintained where we send modern code to browsers but do not test to the same level as A, thus we prioritise bug fixes lower.

PHP
MediaWiki的最新稳定分支（）可运行在PHP 到PHP 7之间的版本. 请注意MediaWiki尚未完全兼容PHP 7.1，并将弹出警告消息，但大多数功能应该能够正常工作. 维基媒体基金会在HHVM上运行MediaWiki. 不在维基媒体wiki上使用的功能目前可能不会在HHVM上正常工作.

MediaWiki 1.23 and 1.27 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. MediaWiki provides database abstraction layers for PostgreSQL and SQLite, which are generally well-maintained. The included abstraction layers for Oracle and Microsoft SQL Server are essentially unmaintained and are unlikely to work out of the box. 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是最经常使用且测试过的. HHVM and nginx are good choices as well.
