PHP Bug Type: Session related
Bug description: session_start Warnings caught by error handler produce E_Fatal
Description:
------------
Abstract: when handling php errors via set_error_handler() with the
intention of throwing a catchable error, an E_FATAL error is triggered.
Details: This is similar to the error you might see when attempting to
throw an exception from an objects destructor. The internal pointer to the
unwinding stack is lost and/or blown away.
without the error handler session_start with an invalid save_path will
produce an E_WARNING
Reproduce code:
---------------
<?
ini_set('session.save_path', '/var/log');
set_error_handler('save_handler', E_ALL);
try {
session_start();
} catch (Exception $e) {
echo $e->getMessage();
}
function save_handler($errno, $errmsg)
{
throw new Exception('Error caught and thrown as exception: ' .
$errmsg);
}
Expected result:
----------------
Error caught and thrown as exception: session_start():
open(/var/log/sess_3e97dad0fe4ce6f285e97593471f2c88, O_RDWR) failed:
Permission denied (13)
Actual result:
--------------
Error caught and thrown as exception: session_start():
open(/var/log/sess_3e97dad0fe4ce6f285e97593471f2c88, O_RDWR) failed:
Permission denied (13)
Fatal error: Exception thrown without a stack frame in Unknown on line 0
