Description of problem: 1) /usr/share/mediawiki/opensearch_desc.php is not symlinked to /var/www/wiki by default, so links to it served out in <head>s of wiki pages don't work. 2) Adding a symlink to it /var/www/wiki isn't sufficient to get it to work, because it contains the line require_once ( dirname(__FILE__) . '/includes/WebStart.php' ); and dirname(__FILE__) is incorrect when running opensearch_desc.php from /var/www/wiki/opensearch_desc.php. In order to fix this, I had to change that line to: require_once( '/usr/share/mediawiki/includes/WebStart.php' ); Since a link to this script is served on every MW page, and a lot of browsers request it automatically, having no symlink or a bad require path can generate a huge number of errors in Apache's error_log. Version-Release number of selected component (if applicable): mediawiki-1.15.4-54.fc13.x86_64 How reproducible: Always Steps to Reproduce: 1. Configure MW. 2. Browse to /wiki/opensearch_desc.php. Actual results: 404 Not Found. Expected results: An XML file produced by opensearch_desc.php. Additional info: This is basically the same issue as Bug 484855 was for api.php.
Addendum: I also needed to add chdir('/usr/share/mediawiki'); to opensearch_desc.php.
