Operating system: Linux
PHP version: 5.1.4
PHP Bug Type: DOM XML related
Bug description: DOMElement->setAttribute() loops forever (node_list_unlink
bug?)
Description:
------------
That another setAttribute() -call never finishes, and the script will just
eventually die because of "PHP Fatal error: Maximum execution time.." I
have tried this with cgi and cli versions of PHP 5.1.4, 5.1.1 and 5.0.5 on
different servers (and different ISPs).
When running, php-process takes all CPU. I tried to debug it with gdb and
node_list_unlink seems to be calling itself forever.
Reproduce code:
---------------
$doc = new DOMDocument();
$doc->resolveExternals = true;
$doc->loadXml('<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";><a b="" />');
$root = $doc->getElementsByTagName('a')->item(0);
$root->setAttribute('b', '>');
$root->setAttribute('b', '');
// This will never be executed
echo "done\n";
Expected result:
----------------
Script prints "done\n"
Actual result:
--------------
Fatal error: Maximum execution time of 180 seconds exceeded in phpbug.php
on line 8 (that is the another setAttribute-call)
