#29070 [NEW]: __get/__set should allow recursive calls

From: csmoak at andrew dot cmu dot edu Operating system: All PHP version: 5.0.0RC3 PHP Bug Type: Feature/Change Request Bug description: __get/__set should allow recursive calls Description: ------------ __get() and __set() are currently blocked from being implicitly called for a particular instance of an object when they are currently executing. However, this can cause code to behave differently if it is called from within __get()/__set() or if it is called without __get()/__set(). The following example uses good OOP methodology that tries to make use of __get() and __set(), but is hindered by it, instead. The problem lies in the use of the in_get and in_set member variables in the zend_object strcut to provide a blanket block to calling __get or __set recursively (when called implicitly). A possible solution would be to only prevent code directly in the __get() and __set() method bodies from implicitly calling __get() or __set(), but allowing it in any called code. Reproduce code: --------------- http://www.andrew.cmu.edu/user/csmoak/getset.phps Expected result: ---------------- correct behavior (without making use of __get/__set):<br> before set : default<br> after set : propertyValue<br> PropertyAccessClass Object ( [property:private] => propertyValue [defaultProperty:private] => default [changed:private] => 1 ) <br><br> incorrect behavior (making use of __get/__set):<br> before set : default<br> after set : propertyValue<br> PropertyAccessClass Object ( [property:private] => propertyValue [defaultProperty:private] => default [changed:private] => 1 ) Actual result: -------------- correct behavior (without making use of __get/__set):<br> before set : default<br> after set : propertyValue<br> PropertyAccessClass Object ( [property:private] => propertyValue [defaultProperty:private] => default [changed:private] => 1 ) <br><br> incorrect behavior (making use of __get/__set):<br> <br /> <b>Notice</b>: Undefined property: PropertyAccessClass::$PropertyChanged in <b>C:\ftproot\pnet\test2.php</b> on line <b>22</b><br /> <br /> <b>Notice</b>: Undefined property: PropertyAccessClass::$DefaultProperty in <b>C:\ftproot\pnet\test2.php</b> on line <b>33</b><br /> before set : <br> after set : propertyValue<br> PropertyAccessClass Object ( [property:private] => propertyValue [defaultProperty:private] => default [changed:private] => [PropertyChanged] => 1 ) -- Edit bug report at http://bugs.php.net/?id=29070&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=29070&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=29070&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=29070&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=29070&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=29070&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=29070&r=needscript Try newer version: http://bugs.php.net/fix.php?id=29070&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=29070&r=support Expected behavior: http://bugs.php.net/fix.php?id=29070&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=29070&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=29070&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=29070&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=29070&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=29070&r=dst IIS Stability: http://bugs.php.net/fix.php?id=29070&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=29070&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=29070&r=float
