[edit] Description

Among other things this file contains:

• Function checkInitialQueries which creates a Title object depending on the title parameter passed to index.php. If the oldid parameter is passed, it will override the title if it's not a special page.
• Function initialize which does the most of the work. It calls:
  • preliminaryChecks
  • initializeSpecialCases, and if that function return false:
  • initializeArticle
  • performAction if initializeArticle returned an article
• Function preliminaryChecks which checks that the page can be seen by the current, and output an error if not.
• Function initializeSpecialCases (called by initialize) it returns true if it matched a special case (see the list below) and false if the request should continue. Special cases handled by this function:
  • Invalid title
  • Redirects to interwikis links
  • Local redirects if, e.g., no title parameter passed to index.php, ...
  • Special pages
• Function initializeArticle, which creates an Article object from the Title given. Then it checks if it is a redirect and if it's the case, recreate another Article from the target of the redirect and changes $wgTitle and $wgArticle. It can return either:
  • An article object, which will be passed performAction to execute the requested action
  • A string if it's an interwiki redirect or a redirect to a special page
• Function performAction (called by initialize) which performs most actions, including creating the HTML. For example, in the case of viewing a page, function "view" in Article.php is called.
• Function finalCleanup (called by index.php) which does the following:
  • Deferred updates
  • Jobs
  • Flushes out all HTML by calling OutputPage::output() .
