我正在尝试基于 Mediawiki 为我的公司建立知识库。

我已经在我自己的 VDS（debian、apache 2.2.16. php 5.3.3.7）上安装并配置了 Mediawiki 1.21.2 。我使用了 Sphinx 搜索引擎和 SphinxSearch Mediawiki 扩展。

但现在我尝试在生产虚拟服务器（CentOS、apache 2.2.15+nginx 1.0.15、php 5.3.3 和 Mediawiki 1.21.3）上做同样的事情，但在搜索时遇到了一些问题：

当我发出一个应该明确返回一些值的搜索请求时，nginx 显示502 Bad Gateway错误。如果没有要返回的信息，则会显示通常的 MediaWiki 消息。

在apache 日志中，我看到以下内容：

[Wed Dec 04 14:06:27 2013] [notice] child pid 12603 exit signal Segmentation fault (11)

在站点的错误日志中，只有一些关于 StrictStandart 的警告：

[Wed Dec 04 11:30:09 2013] [error] [client 127.0.0.1] PHP Strict Standards:  Declaration of SphinxMWSearch::userHighlightPrefs() should be compatible with that of SearchEngine::userHighlightPrefs() in /var/www/vhosts/itkgwiki/extensions/SphinxSearch/SphinxMWSearch.php on line 15, referer: http://my-site/pagename

然后转到mediawiki 日志文件：

我的技能太差，无法从中做出决定，所以我很乐意提供任何建议。

基本上，问题似乎在于，在 MediaWiki 1.18 中，SearchEngine::userHighlightPrefs() 方法已更改为不再将 User 对象作为参数。不幸的是，此更改导致任何覆盖该方法的现有子类在 PHP 严格模式下中断。

坦率地说，我认为这是一个糟糕的决定：应该由第三方代码子类化的类不应该在没有充分理由的情况下随意更改其方法签名。也就是说，它发生在两年多前，所以现在要求恢复它可能有点晚了。最好的办法可能是弃用整个混乱并修复所有扩展以不使用它；事实上，这早就应该完成了，但很巧合的是，SphinxSearch 扩展最近一直缺乏维护关注。

无论如何，有几种方法可以自己解决这个问题：

  • 我推荐的修复方法是将 SphinxSearch 升级到最新版本，最近删除了有问题的方法覆盖。不过，我不太确定这是否完全解决了问题，因为似乎仍然使用额外的 User 参数从部分代码调用该方法。但如果没有，那么这是扩展程序中的一个错误，应该报告。

  • 您还可以自己修改 SphinxSearch 代码，删除自定义 userHighlightPrefs() 方法和对其的任何调用。如果您确实以这种方式工作（首先升级到最新版本之后），您可能希望将您的更改作为补丁提交。

  • 最后，正如在 mediawiki.org 上的讨论中所建议的那样，您可以简单地在 php.ini 中关闭严格模式，例如通过设置：

    error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT
