Bug description: Memory Limit bypasses set_error_handler
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.
