It appears that upgrading a MediaWiki 1.8 installation to 1.9-svn will break operation of extensions such as DPLforum 2.1.1 extension, even if they had been working properly under 1.8 The errors occur in the call to getMaxIncludeSize() in includes/Parser.php, line 2772 in the current version: function replaceVariables( $text, $args = array(), $argsOnly = false ) { # Prevent too big inclusions if( strlen( $text ) > $this->mOptions->getMaxIncludeSize() ) { return $text; } Comment out that one if/return and the wiki (with the extension) becomes usable again. On access to any page with the <forum> tag, symptom is just a blank screen - error logs indicate the code breaks as this one test fails with: [Tue Dec 26 13:47:04 2006] [error] [client 127.0.0.1] PHP Fatal error: Call to a member function getMaxIncludeSize() on a non-object in /var/www/html/test/includes/Parser.php on line 2772 So changes made to core code are breaking things elsewhere. :(
After a quick read-through of the extension code itself, I rather suspect that this breakage is due to the extension's authoring being somewhat out of date; it seems to be declaring new parsers within parse runs, interacting with the global parser within said runs, interacting with globals such as $wgUser when it should be referring to the ParserOptions of the parent parser, etc. To be honest, I'm not surprised it's broken.
