Edit report at https://bugs.php.net/bug.php?id=55300&edit=1 ID: 55300 User updated by: frederic dot hardy at mageekbox dot net Reported by: frederic dot hardy at mageekbox dot net Summary: \DirectoryIterator, parent::__construct() and \LogicException Status: Open Type: Bug Package: SPL related Operating System: Linux PHP Version: 5.4.0alpha2 Block user comment: N Private report: N New Comment: This BC break is a problem with the symfony 2 framework. All command throw this exception : [LogicException] In the constructor of Symfony\Component\Finder\SplFileInfo, parent::__construct() must be called and its exceptions cannot be cleared Previous Comments: ------------------------------------------------------------------------ [2011-07-28 08:44:49] pajoye@php.net Thing is that it is a bc break, whether it was well designed in the 1st place or not is sadly not relevant here. Is there any way to restore this behavior without bc breaks? ------------------------------------------------------------------------ [2011-07-28 08:29:38] cataphract@php.net Why can't you use a user stream wrapper then? Maybe DirectoryIterator should be an interface, but it isn't. ------------------------------------------------------------------------ [2011-07-28 07:27:19] frederic dot hardy at mageekbox dot net This bug seems to be related to #54384. And i want to do this to mock a \DirectoryIterator instance, to "simulate" a directory on the file system. ------------------------------------------------------------------------ [2011-07-27 23:30:06] cataphract@php.net If you don't call the parent constructor, the class has no functionality. Why would you want to do this? ------------------------------------------------------------------------ [2011-07-27 15:36:56] frederic dot hardy at mageekbox dot net Description: ------------ In PHP 5.4, an exception was throwed if a call to parent::__construct() is not done in the constructor of a class which extends \DirectoryIterator. Exception was not throwed in previous version of PHP, so it's a BC break. And this BC break must be annoying in unit test, because it's impossible to mock the \DirectoryIterator class. Test script: --------------- <?php class myDirectoryIterator extends \DirectoryIterator { public function __construct() { } } $directoryIterator = new myDirectoryIterator(); ?> Expected result: ---------------- Nothing. Actual result: -------------- Fatal error: Uncaught exception 'LogicException' with message 'In the constructor of myDirectoryIterator, parent::__construct() must be called and its exceptions cannot be cleared' in /path/to/directoryIterator.php:10 Stack trace: #0 /path/to/directoryIterator.php(10): myDirectoryIterator->internal_construction_wrapper() #1 {main} thrown in /path/to/directoryIterator.php on line 10 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55300&edit=1
