ID: 37013 Updated by: sniper@php.net Reported By: hjiverson at plauditdesign dot com -Status: Open +Status: Assigned Bug Type: SOAP related Operating System: Gentoo Linux PHP Version: 5CVS-2006-04-07 (snap) -Assigned To: +Assigned To: dmitry New Comment: Assigned to the maintainer. Previous Comments: ------------------------------------------------------------------------ [2006-04-07 21:18:44] hjiverson at plauditdesign dot com Description: ------------ When I return a graph of objects that has circular references (a tree of categories, for example), the soap server gets stuck in an infinite loop/recursion and hangs. Reproduce code: --------------- http://dev.plauditdesign.com/~hjiverson/drop/php-soap-multiref-bug.txt Expected result: ---------------- The server should use mutliRefs and create references to each object. Each object instance would be serialized one time and given a unique ID, which is then pointed to each time an reference to that object is encountered. Something like this: <getThingWithParentResponse> <result href="#object1"/> </getThingWithParentResponse> ... <multiRef xsi:type="ThingWithParent" id="object1"> ... <parent xsi:nil="1"/> <children> <child href="#object2"/> </children> </multiRef> <multiRef xsi:type="ThingWithParent" id="object2"> ... <parent href="#object1"/> <children xsi:nil="1"/> </multiRef> Actual result: -------------- php hangs ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37013&edit=1
