How A Page is Built
(From Woozle 21:59, 15 Jun 2005 (EDT).)
- Everything obviously starts with index.php
- For the purpose of displaying a page (not saving changes or doing anything else), this calls $wgArticle->view(), in Article.php (line 699)
- $wgArticle->view() appears to be able to provide a few other formats besides the regular view (including difference engine and displaying redirections as subtitles), but I'm ignoring that for now
- $wgOut seems to be the object which accumulates text to be output. It is created in Setup.php:
- $wgOut = new OutputPage();
- OutputPage() is defined in OutputPage.php
- After being created, $wgOut accumulates output via various class methods:
- $wgOut->addWikiText(...)
- $wgOut->addHTML(...)
- $wgOut->addPrimaryWikiText() # Display content and save to parser cache
- $wgOut->addWikiText() # Display content, don't attempt to save to parser cache
- $wgOut->setPageTitle()
- $wgOut->transformBuffer(); # Put link titles into the link cache
- $wgOut->addMetaTags(); # Add link titles as META keywords
- ...and then it does these two lines:
- $this->viewUpdates(); (found at line 1926 -- doesn't do much)
- wfProfileOut( $fname );
- It's not clear whether the navbar has already been pulled in by the time we hit viewUpdates -- possibly transformBuffer does it? The comment makes it sound like that, but the name "transformBuffer" in that case is not very descriptive. The code in there should probably be examined.
