--- Comment #1 from Bartosz Dziewoński <matma....@gmail.com> ---
The current code for this is in WikitextContent, and the regex does look
stricter.
The regex itself was changed back in 2008, though, in r38737 by Roan (with a
reference to bug 15053), and made a bit more relaxed (accepting the colon) in
2008 too in r38974 by Brion.
----
The current code for reference:
public function getRedirectTarget() {
global $wgMaxRedirects;
if ( $wgMaxRedirects < 1 ) {
// redirects are disabled, so quit early
return null;
}
$redir = MagicWord::get( 'redirect' );
$text = trim( $this->getNativeData() );
if ( $redir->matchStartAndRemove( $text ) ) {
// Extract the first link and see if it's usable
// Ensure that it really does come directly after #REDIRECT
// Some older redirects included a colon, so don't freak about that!
$m = array();
if ( preg_match( '!^\s*:?\s*\[{2}(.*?)(?:\|.*?)?\]{2}!', $text, $m ) ) {
// Strip preceding colon used to "escape" categories, etc.
// and URL-decode links
if ( strpos( $m[1], '%' ) !== false ) {
// Match behavior of inline link parsing here;
$m[1] = rawurldecode( ltrim( $m[1], ':' ) );
}
$title = Title::newFromText( $m[1] );
// If the title is a redirect to bad special pages or is invalid, return
null
if ( !$title instanceof Title || !$title->isValidRedirectTarget() ) {
return null;
}
return $title;
}
}
return null;
}
