#19243 [Opn->Fbk]: Seg Fault Restoring Session Variables with References to Objects

ID: 19243 Updated by: kalowsky@php.net Reported By: fdruseikis@sc.rr.com -Status: Open +Status: Feedback Bug Type: Session related Operating System: Linux RH 7.0 PHP Version: 4.2.2 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip Once again, as code has changed yet again. Give it a try. :) Previous Comments: ------------------------------------------------------------------------ [2002-09-06 09:24:22] fdruseikis@sc.rr.com To elaborate on what I see: In php4.3.0-dev If there are any references within an array/object you don't serialize it. Otherwise it is serialized. So, array( 1, 2, 3) and array( new TFoo(1), new TFoo(2) ) save and restore. However, in php4.3.0-dev global $a; $a = array(null,null) $a[0] =& new TFoo(1); $a[1] =& $a[0]; $a serializes as null. This would be a change from 4.2.2, which permits this latter example (but segfaults on the global $o1, $o2 of the original bug report). In 4.2.2 $a example does not segfault and the restored array has references to the same object instance. Did you want to take away functionality? ------------------------------------------------------------------------ [2002-09-06 08:16:38] fdruseikis@sc.rr.com Also: doesn't save/restore arrays either. ------------------------------------------------------------------------ [2002-09-06 08:03:59] fdruseikis@sc.rr.com I tried the script on this build: php4-200209060300 (linux) No segfault. However, both variables $o1 and $o2 are saved (and restored) as null. This results in a "Fatal Error: Call to a member function on a non-object in ..." Both $o1 and $o2 should refer to the original (singleton) object instance. ------------------------------------------------------------------------ [2002-09-05 16:48:14] kalowsky@php.net keeping set as feedback ------------------------------------------------------------------------ [2002-09-05 16:41:24] fdruseikis@sc.rr.com I'll give it a try. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
