Bug description: Error handling when out of memory
Description:
------------
I have a PHP production setup where errors are automatically reported to
me via email, by using a custom error handler.
However, when PHP reaches it's memory limit the custom error handler is
disabled. As a result, I may not be notified of OOM errors.
It would be nice if PHP did one of two things:
1) Emit an E_WARNING the first time the script reaches 99% (or something
like that, maybe configurable) of memory_limit.
2) When the program reaches the memory limit the first time, add fx 1MB
(perhaps user configurable) to the memory limit, emit an OOM E_WARNING, and
let the custom error handler handle the error. The next time the memory
limit is reached then really die.
I would prefer 1)
Reproduce code:
---------------
<?php
function custom_error_handler($error_code, $error_string, $filename,
$line, $symbols) {
die("This is the custom error handler");
}
set_error_handler('custom_error_handler');
$i = 0;
$a = Array();
while (true) {
$a[$i] = $i++;
}
?>
Expected result:
----------------
It would be nice if my custom error handler was allowed to run.
Actual result:
--------------
[EMAIL PROTECTED] ~/php_oom> php test.php
Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to
allocate 35 bytes) in /home/thue/php_oom/test.php on line 10
