From 63be0062b6f24d81a4ea78a1946ff3688667b49f Mon Sep 17 00:00:00 2001 From: Matthew Exon Date: Wed, 27 Feb 2013 07:34:40 +0800 Subject: [PATCH] For very large posts (~18k) with lots of markup, these regexes were causing enough backtracking for php to run out of memory, silently generating an empty entry. This tightens up the regexes so they do less backtracking. --- include/bbcode.php | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/include/bbcode.php b/include/bbcode.php index a587d8c38..cec13d919 100644 --- a/include/bbcode.php +++ b/include/bbcode.php @@ -642,8 +642,8 @@ function bbcode($Text,$preserve_nl = false, $tryoembed = true, $simplehtml = fal $Text = preg_replace('/\"\;/','"',$Text); // fix any escaped ampersands that may have been converted into links - $Text = preg_replace("/\<(.*?)(src|href)=(.*?)\&\;(.*?)\>/ism",'<$1$2=$3&$4>',$Text); - $Text = preg_replace("/\<(.*?)(src|href)=\"[^hfm](.*?)\>/ism",'<$1$2="">',$Text); + $Text = preg_replace("/\<([^>]*?)(src|href)=(.*?)\&\;(.*?)\>/ism",'<$1$2=$3&$4>',$Text); + $Text = preg_replace("/\<([^>]*?)(src|href)=\"[^hfm](.*?)\>/ism",'<$1$2="">',$Text); if($saved_image) $Text = bb_replace_images($Text, $saved_image);
