Bug #72532 [NEW]: try/catch, set_error_handler & not catching Excpetion on require(_once)/include

From: B at DAMNGOOD dot one Operating system: Linux (Ubuntu tested) PHP version: Irrelevant Package: *Directory/Filesystem functions Bug Type: Bug Bug description:try/catch, set_error_handler & not catching Excpetion on require(_once)/include Description: ------------ Surely this has everything to do with this ticket, which, suprisingly has not been addressed since (in 5.5.6) and seems to be lingering on in PHP ever since who knows when up till (7.0.4)! I would consider it to be quite odd that so few people have voted for this ticket, so here comes again, maybe with a bit of a clearer description and the scope of the affected version of PHP. The open ticket I found about this: https://bugs.php.net/bug.php?id=66216&thanks=6 When set_error_handler is set, making a try/catch block with require(_once) in it, will produce an uncaught exception. When you do this with include, however, the error *is* caught as an exception. Test script: --------------- <?php function errorHandler($errno, $errstr, $errfile, $errline, $errcontext) { throw new Exception("this was an error"); } function exceptionHandler($e) { echo 'exceptionHandler'; } set_error_handler('errorHandler'); set_exception_handler('exceptionHandler'); try { require('barf'); // there is no barf, but here we creating some ourselves require_once('barf'); } catch (Exception $ex) { // this never happens echo $ex->getMessage(); } Expected result: ---------------- this was an error Actual result: -------------- Code and response producing the unexpected result with require(_once): $ php <?php function errorHandler($errno, $errstr, $errfile, $errline, $errcontext) { throw new Exception("this was an error"); } function exceptionHandler($e) { echo 'exceptionHandler'; } set_error_handler('errorHandler'); set_exception_handler('exceptionHandler'); try { require('barf'); } catch (Exception $ex) { echo $ex->getMessage(); } PHP Warning: Uncaught exception 'Exception' with message 'this was an error' in -:4 Stack trace: #0 -(15): errorHandler(2, 'require(barf): ...', '-', 15, Array) #1 -(15): require() #2 {main} thrown in - on line 4 PHP Stack trace: PHP 1. {main}() -:0 Warning: Uncaught exception 'Exception' with message 'this was an error' in -:4 Stack trace: #0 -(15): errorHandler(2, 'require(barf): ...', '-', 15, Array) #1 -(15): require() #2 {main} thrown in - on line 4 Call Stack: 28.3487 234552 1. {main}() -:0 PHP Fatal error: main(): Failed opening required 'barf' (include_path='.:/usr/share/php:/usr/share/pear') in - on line 15 PHP Stack trace: PHP 1. {main}() -:0 Fatal error: main(): Failed opening required 'barf' (include_path='.:/usr/share/php:/usr/share/pear') in - on line 15 Call Stack: 28.3487 234552 1. {main}() -:0 Code that DOES work, using include instead: $ php <?php function errorHandler($errno, $errstr, $errfile, $errline, $errcontext) { throw new Exception("this was an error"); } function exceptionHandler($e) { echo 'exceptionHandler'; } set_error_handler('errorHandler'); set_exception_handler('exceptionHandler'); try { include('barf'); } catch (Exception $ex) { echo $ex->getMessage(); } // output: this was an error -- Edit bug report at https://bugs.php.net/bug.php?id=72532&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72532&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72532&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72532&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72532&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72532&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72532&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72532&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72532&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72532&r=support Expected behavior: https://bugs.php.net/fix.php?id=72532&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72532&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72532&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72532&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72532&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72532&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72532&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72532&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72532&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72532&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72532&r=mysqlcfg
