From: mattsch at gmail dot com Operating system: Gentoo PHP version: 5.3.20 Package: Class/Object related Bug Type: Feature/Change Request Bug description:Implement exception chaining within core classes
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 bug report at https://bugs.php.net/bug.php?id=63873&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63873&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63873&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63873&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63873&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63873&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63873&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63873&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63873&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63873&r=support Expected behavior: https://bugs.php.net/fix.php?id=63873&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63873&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63873&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63873&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63873&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63873&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63873&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63873&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63873&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63873&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63873&r=mysqlcfg
