If there's a lot of source code in a <source> tag, the syntax highlighter crashes and the user gets a blank screen. It would be better to fall back to a plain <pre> block instead of syntax highlighting in that case, or something.
Can you provide more details than just "blank page". Check the server logs or increase error reporting. If it is out of memory error I'm afraid there is nothing we can do. Which version of Geshi are you using?
MediaWiki 1.16alpha (i.e. trunk/phase3), at r56407, SyntaxHighlight_GeSHi Version 1.0.8.5 (r56284) according to Special:Version. I see nothing relevant in the MW debug output. I have in php.ini: error_reporting = E_ALL & ~E_NOTICE Anyway, there seems to be more than one way to crash it with oversize inputs. On a Special: page that uses the source tag I see: [Wed Sep 16 20:29:09 2009] [notice] child pid 25365 exit signal Segmentation fault (11) and on a mainspace page that includes a source tag I see: [Wed Sep 16 20:42:56 2009] [error] [client 127.0.0.1] PHP Fatal error: Allowed memory size of 52428800 bytes exhausted (tried to allocate 16 bytes) in /usr/src/mediawiki-extensions-trunk/SyntaxHighlight_GeSHi/geshi/geshi.php on line 3744 So at least some of the time it's an out of memory. I'm going to consider imposing a file size limit and just using <pre> for bigger ones.
