#31905 [Opn->Bgs]: Memory Limit bypasses set_error_handler

ID: 31905 Updated by: iliaa@php.net Reported By: ceo at l-i-e dot com -Status: Open +Status: Bogus Bug Type: *Programming Data Structures Operating System: FreeBSD 4.10-STABLE PHP Version: 4.3.10 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php memory limit error is a fatal E_ERROR that cannot be captured by php's error handler. Previous Comments: ------------------------------------------------------------------------ [2005-02-09 19:00:25] ceo at l-i-e dot com Description: ------------ set_error_handle seems totally ineffective for Memory Limit settings. Reproduce code: --------------- ini_set('memory_limit', '32K'); ini_set('error_reporting', 0); echo "Memory Limit: ", ini_get('memory_limit'), "\n"; echo "Memory Used: ", memory_get_usage(), "\n"; function error_handler($error, $message, $file, $line){ echo "Error ($error) in $file:$line - $message\n"; return true; } set_error_handler('error_handler'); trigger_error("Test", E_USER_NOTICE); $str = str_repeat('a', 1024); while (true){ echo '.'; flush(); $str .= $str; } echo "\nMade it!\n"; Expected result: ---------------- I expected to see the same error message PHP usually reports, more or less, and then "Made it!". Actual result: -------------- -bash-2.05b$ php test.php Content-type: text/html X-Powered-By: PHP/4.3.10 Memory Limit: 32K Memory Used: 13432 Error (1024) in /www/l-i-e.com/web/test.php:12 - Test ....-bash-2.05b$ Note that my test error message comes out, and PHP continues, but upon reaching memory limit, it just dies, with no call to my error handler. :-( I'm not sure that a soft limit imposed should necessarily be considered non-recoverable... Though I can see how even trying to call the function at that point is problematic, in terms of not triggering the error again in an infinite loop... Still, it would be nice to be able to trap this and do something useful rather than just die, if possible. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31905&edit=1
