Enforcing DisableCache

In MediaWiki version 1.6 and early versions of 1.7, extensions cannot prevent articles from being cached when edited. A function in Article.php, editUpdates(), is called unilaterally. (See bugzilla:5683.) To restore expected behavior in these extensions, the following change must be made to Article.php.

In Article::editUpdates(), find this section of code:

		# Save it to the parser cache
		$parserCache =& ParserCache::singleton();
		$parserCache->save( $poutput, $this, $wgUser );

Then, replace it with this:

		# Save it to the parser cache
		if( $poutput->mCacheTime != -1 )
		{
			$parserCache =& ParserCache::singleton();
			$parserCache->save( $poutput, $this, $wgUser );
		}

WARNING: This hack has not been tested with squid or other external caching systems. Use at your own risk.
