Wikipedia is running CrossNamespaceLinks according to Special:Version revision 37404. When you install this revision from SVN it breaks the system. A traceback informs you about this: Aliases file does not exist: /var/www/revisions/WMF_testsystem/extensions/CrossNamespaceLinks/SpecialCrossNamespaceLinks.alias.php Backtrace: #0 /var/www/revisions/WMF_testsystem/includes/SpecialPage.php(240): Language->getSpecialPageAliases() #1 /var/www/revisions/WMF_testsystem/includes/SpecialPage.php(262): SpecialPage::initAliasList() #2 /var/www/revisions/WMF_testsystem/includes/SpecialPage.php(406): SpecialPage::resolveAlias('Version') #3 /var/www/revisions/WMF_testsystem/includes/SpecialPage.php(507): SpecialPage::getPageByAlias('Version') #4 /var/www/revisions/WMF_testsystem/includes/Wiki.php(229): SpecialPage::executePath(Object(Title)) #5 /var/www/revisions/WMF_testsystem/includes/Wiki.php(59): MediaWiki->initializeSpecialCases(Object(Title), Object(OutputPage), Object(WebRequest)) #6 /var/www/revisions/WMF_testsystem/index.php(116): MediaWiki->initialize(Object(Title), NULL, Object(OutputPage), Object(User), Object(WebRequest)) #7 {main} When you install the extension without specifying the revision, it installs completely and it still advertises the same revision. My conclusion is that SVN is confused and needs a new revision for CrossNamespaceLinks. Thanks, GerardM
You cannot rely on the version number shown on Special:Version because it shows the revision of the base file only. In the current case the alias file was committed separatly (by accident?) with revision r37404. A few weeks ago there was a short discussion about the use of revision number in Special:Version.
If you cannot rely on that number, you can not build a test environment that mimics the current Wikipedia production system. When Brion creates the latest mix and match for the production environment, all the extensions are 15a even when he does not include it in what goes life. The information has to be good. Currently it breaks the system. Thanks, GerardM
r37404 would be very old and obsolete, this is irrelevant. Wikimedia has the same SVN version of extensions installed as it has MediaWiki, except where mentioned otherwise in our server admin log -- http://wikitech.wikimedia.org/view/Server_admin_log
