ID: 55801 Updated by: johan...@php.net Reported by: mapi at pdepend dot org Summary: Behavior of unserialize has changed Status: Feedback Type: Bug Package: Variables related Operating System: Linux (Fedora 15) PHP Version: 5.4.0beta1 Block user comment: N Private report: N New Comment: Can you try reverting SVN revision r299770 and then run your test? - That's mostly a guess, though. bug #36424 http://svn.php.net/viewvc/?view=revision&revision=299770 Previous Comments: ------------------------------------------------------------------------ [2011-09-28 16:29:50] mapi at pdepend dot org It seems that this has something todo with the visibility of properties that should be serialized. If I do the following: ~ $ rm -rf ~/.pdepend ~ $ git clone https://github.com/pdepend/pdepend.git ~ $ cd pdepend ~ $ vim src/main/php/PHP/Depend/Code/AbstractClassOrInterface.php +86 -> Change from PROTECTED to PUBLIC protected $parentClassReference = null; -> public $parentClassReference = null; ~ $ vim src/main/php/PHP/Depend/Code/AbstractClassOrInterface.php +132 -> Change from PROTECTED to PUBLIC protected $nodes = array(); -> public $nodes = array(); ~ $ php540 src/bin/pdepend.php --summary-xml=sum.xml src/main/php/PHP/Depend/Code/ASTArrayType.php ~ $ php540 src/bin/pdepend.php --summary-xml=sum.xml src/main/php/PHP/Depend/Code/ASTArrayType.php ... Executing CyclomaticComplexity-Analyzer: Fatal error: Call to a member function findChildrenOfType() on a non-object in /tmp/pdepend/src/main/php/PHP/Depend/Code/AbstractClassOrInterface.php on line 268 If I now revert the visibility of both properties from PUBLIC to PROTECTED, it works: ~ $ vim src/main/php/PHP/Depend/Code/AbstractClassOrInterface.php +86 -> Change from PUBLIC to PROTECTED public $parentClassReference = null; -> protected $parentClassReference = null; ~ $ vim src/main/php/PHP/Depend/Code/AbstractClassOrInterface.php +132 -> Change from PUBLIC to PROTECTED public $nodes = array(); -> protected $nodes = array(); ~ $ php540 src/bin/pdepend.php --summary-xml=sum.xml src/main/php/PHP/Depend/Code/ASTArrayType.php This means that a PUBLIC property that was serialized can be restored in a PROTECTED property while unserializing the object structure. ------------------------------------------------------------------------ [2011-09-28 15:20:33] mapi at pdepend dot org Yes, here you can get the two serialized object structures: http://manuel-pichler.de/stuff/5.3.ser http://manuel-pichler.de/stuff/5.4.ser And there is the difference: 5.3 -> *nodes";a:1:{i:0;r:18;}}}}}}}}} 5.4 -> *nodes";a:1:{i:0;r:36;}}}}}}}}} It references something different. ------------------------------------------------------------------------ [2011-09-28 13:41:54] paj...@php.net Any chance to get something that shows us the serialized data with 5.4 and 5.4 so we can see how they differ? Maybe upload the small possible code somewhere? ------------------------------------------------------------------------ [2011-09-28 13:30:46] mapi at pdepend dot org Okay, I tried for several hours to create a reproducable outside of PHP_Depend's context, but I cannot reproduce this behavior :( But at least I came up with a small code fragement that illustrates this behavior: <?php class Test { function method() { $this->prop[$y]++; } } which was translated into the following object graph: Statement Expression MemberPrimaryPrefix <---------- Variable | PropertyPostfix | ArrayIndexExpression [Same Instance] Identifier | Variable | PostfixExpression | MemberPrimaryPrefix ---------- Variable PropertyPostfix ArrayIndexExpression Identifier Variable And this second reference to MemberPrimaryPrefix is NULL after unserialization with PHP 5.4 and it is just a second clone with PHP < 5.4 ------------------------------------------------------------------------ [2011-09-28 08:56:52] mapi at pdepend dot org I will try to create a reproducable. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
