From: Operating system: GNU/Linux 2.6.26-2-686 (Debian) PHP version: 5.3SVN-2010-09-06 (snap) Package: DOM XML related Bug Type: Bug Bug description:DOMDocument subclass forgotten using ->ownerDocument after closure
Description: ------------ We have custom XML document and element classes that extend the original DOMDocument and DOMElement classes for convenience. There is a class that uses an instance of XmlElement obtained via a callback specified at construction time. That XmlElement works fine and stays that way. However, when we get its ownerDocument outside of the closure, the result is not an XmlDocument but a DOMDocument. I cannot see a single reason why. I tried several options, and it only seems to happen with that closure. I have checked versions 5.3.1, 5.3.2, 5.3.3 and now the latest 5.3.4 snapshot compiled with './configure && make'. Test script: --------------- http://codepad.org/hvrNh86K The original code uses a lot of namespaces and extends XmlDocument, but this is a much more minimal test case. Also try the "Uncomment this" code to see what /does/ work. Expected result: ---------------- *** Calling the callback directly... dom-fail.php:110: $container: XmlElement: <div id="content"/> dom-fail.php:111: $container->ownerDocument: XmlDocument; debug: object(XmlDocument)#2 (0) refcount(1){ } *** Calling callback from constructor()... dom-fail.php:110: $container: XmlElement: <div id="content"/> dom-fail.php:111: $container->ownerDocument: XmlDocument; debug: object(XmlDocument)#2 (0) refcount(1){ } *** In constructor, after check on $container: dom-fail.php:95: $container: XmlElement: <div id="content"/> dom-fail.php:96: $container->ownerDocument: XmlDocument; debug: object(XmlDocument)#2 (0) refcount(1){ } SUCCESS!
