ID: 63873 User updated by: mattsch at gmail dot com Reported by: mattsch at gmail dot com Summary: Implement exception chaining within core classes -Status: Open +Status: Closed Type: Feature/Change Request Package: Class/Object related Operating System: Gentoo PHP Version: 5.3.20 Block user comment: N Private report: N New Comment: It turns out that this is not necessary. The workaround for this is to catch core exceptions and throw a new exception and pass the previous exception (core exception) into the new exception. Then the exception chain won't be broken. Previous Comments: ------------------------------------------------------------------------ [2012-12-29 16:26:07] mattsch at gmail dot com Description: ------------ php core classes have no way of continuing the exception chain. If we are to have proper exception chaining as implemented in the exception class in php 5.3, we should also have the ability to continue the exception chain within php core classes to make debugging easier. Test script: --------------- <?php class MyCustomException extends Exception {} function doStuff() { try { throw new InvalidArgumentException("You are doing it wrong!", 112); } catch(Exception $e) { try { $pdo = new PDO('foo', 'foo', 'bar', array()); // exception chain lost // $pdo = new PDO('foo', 'foo', 'bar', array(), $e); // needs additional previous exception parameter } catch (Exception $ex) { throw new MyCustomException("Something happened", 911, $ex); } } } try { doStuff(); } catch(Exception $e) { do { printf("%s:%d %s (%d) [%s]\n", $e->getFile(), $e->getLine(), $e->getMessage(), $e->getCode(), get_class($e)); } while($e = $e->getPrevious()); } Expected result: ---------------- Expected result: ---------------- foo.php:13 Something happened (911) [MyCustomException] foo.php:10 invalid data source name (0) [PDOException] foo.php:7 You are doing it wrong! (112) [InvalidArgumentException] Actual result: -------------- Actual result: -------------- foo.php:13 Something happened (911) [MyCustomException] foo.php:10 invalid data source name (0) [PDOException] ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63873&edit=1
