Cannot obtain a diff page To exhibit it: Go to Wikipedia EN Try to obtain the diff between: # (cur) (last) 2006-03-18T08:06:09 67.49.215.239 # (cur) (last) 2006-03-18T08:03:39 Rory096 Problem: it simply hangs the serving process (till timeout) Note: the article ('page') contains a huge line. It seems to me that it somewhat breaks the parser
It loads fine for me.
(Note: the article is 'Golden ratio') Trying to access to the URL associated to this bug seems not possible ('Read Timeout' error) with Iceweasel (Firefox) 2.0.0.1 (Debian x86 package: 2.0.0.1+dfsg-2) and lynx (2.8.5-2sarge2.), either loged under a WP account or as anon.
I get a 500 error, because on of the revisions in question does not appear to be available. http://en.wikipedia.org/w/index.php?title=Golden_ratio&oldid=44320111 Perhaps this is due to bug 20757 ?

No. The revision text is available http://en.wikipedia.org/w/index.php?title=Golden_ratio&oldid=44320111&action=edit As Nat points out, that seems parser related. You can view the diff with http://en.wikipedia.org/w/index.php?title=Golden_ratio&diff=44320111&oldid=44319915&diffonly=1
That line produces: PHP Fatal error: Balloc() allocation exceeds list boundary in includes/parser/Parser.php on line 737 where the relevant lines are: foreach ( $lines as $outLine ) { $line = trim( $outLine ); if ( $line == '' ) { # empty line, go to next line $out .= $outLine."\n"; continue; } The error seems to be comparing a numeric string of 2000016 characters ($line) with the empty string with the == equal. It is fixed by doing a strict comparison (===). Then the error moves at a different point.
Fixed in r67014
