Bug #63163 [NEW]: Unserialisation incorrect in presented scenario

From: james at gadgets4vista dot co dot uk Operating system: OS X 10.8.2 PHP version: 5.4.7 Package: Scripting Engine problem Bug Type: Bug Bug description:Unserialisation incorrect in presented scenario Description: ------------ So far as I can tell this problem is trigged by the serialisation/deserialisation going on in the inheritance hierarchy (ParentA and ParentB) in combination with the re-use (triggering obj references in the serialisation) of ParentB's children in Wrapper. At a guess this is a difference in the table construction between serialize and unserialize (thus ending up referencing the incorrect thing), but I haven't yet taken a look at their implementation so that's a total stab in the dark. Test script: --------------- http://pastie.org/private/vbjpi8ytmqqxi2pkiizatw Expected result: ---------------- object(Wrapper)#6 (2) { ["parent"]=> object(ParentB)#7 (2) { ["collection"]=> array(3) { [0]=> object(Child)#8 (1) { ["property"]=> string(3) "foo" } [1]=> object(Child)#9 (1) { ["property"]=> string(3) "foo" } [2]=> object(Child)#10 (1) { ["property"]=> string(3) "foo" } } ["rofl"]=> string(3) "foo" } ["children"]=> array(3) { [0]=> object(Child)#8 (1) { ["property"]=> string(3) "foo" } [1]=> object(Child)#9 (1) { ["property"]=> string(3) "foo" } [2]=> object(Child)#10 (1) { ["property"]=> string(3) "foo" } } } Actual result: -------------- object(Wrapper)#6 (2) { ["parent"]=> object(ParentB)#7 (2) { ["collection"]=> array(3) { [0]=> object(Child)#8 (1) { ["property"]=> string(3) "foo" } [1]=> object(Child)#9 (1) { ["property"]=> string(3) "foo" } [2]=> object(Child)#10 (1) { ["property"]=> string(3) "foo" } } ["rofl"]=> string(3) "foo" } ["children"]=> array(3) { [0]=> object(Child)#9 (1) { <-- Where'd #8 go? ["property"]=> string(3) "foo" } [1]=> object(Child)#10 (1) { ["property"]=> string(3) "foo" } [2]=> string(20) "1Y" <-- Unexpected } } -- Edit bug report at https://bugs.php.net/bug.php?id=63163&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63163&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63163&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63163&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63163&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63163&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63163&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63163&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63163&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63163&r=support Expected behavior: https://bugs.php.net/fix.php?id=63163&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63163&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63163&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63163&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63163&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63163&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63163&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63163&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63163&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63163&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63163&r=mysqlcfg
