Bug #75215 [NEW]: set_exception_handler callable not called on exception

From: bkfake-php at yahoo dot com Operating system: OSX PHP version: 7.0.23 Package: *General Issues Bug Type: Bug Bug description:set_exception_handler callable not called on exception Description: ------------ exception handler is never called! it appears to me that the exception itself causes the destruction of the object.. which calls exit. this somehow bypasses the exception handler. yet, shutdown function is called! also note: error_get_last() inside the shutdown function returns null.. this is usually where you can catch fatal error (including the fatal error: "uncaught exception"). Here the exception was completely swallowed and never reported PHP's OOP destructor documentation includes this brief "Calling exit() in a destructor will prevent the remaining shutdown routines from executing." a) shutdown function was called, which seems to contradict documentation b) no mention of of exception handler... which seems like it should have been called before the destruction of the objects! same behavior in 5.6 and 7.0 Test script: --------------- <?php class Test { public function myMethod() { echo __METHOD__.'<br />'; echo 'throwing exception<br />'; throw new Exception('hello world?'); } public function __destruct() { echo __METHOD__.'<br />'; exit; } } class Wrapper { public function doIt() { $test = new Test(); $test->myMethod(); } public function __destruct() { echo __METHOD__.'<br />'; } } register_shutdown_function(function () { echo 'shutdown function<br />'; echo 'error_get_last: '.json_encode(error_get_last()).'<br />'; }); set_exception_handler(function ($e) { echo 'exception handler: '.$e->getMessage().'<br />'; }); echo 'Main<br />'; $wrapper = new Wrapper(); $wrapper->doIt(); Expected result: ---------------- exception handler should be called?! output should include "exception handler: hello world?" Actual result: -------------- exception not caught. exception "swallowed" and script exits sans error with http 200 Test script outputs Main Test::myMethod throwing exception Test::__destruct shutdown function error_get_last: null Wrapper::__destruct -- Edit bug report at https://bugs.php.net/bug.php?id=75215&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75215&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75215&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75215&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75215&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75215&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75215&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75215&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75215&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75215&r=support Expected behavior: https://bugs.php.net/fix.php?id=75215&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75215&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75215&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75215&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75215&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75215&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75215&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75215&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75215&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75215&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75215&r=mysqlcfg
