Bug description: set_time_limit() & register_shutdown_function()
Description:
------------
Hi
I'd like to propose a modification to the SET_TIME_LIMIT() and/or the
REGISTER_SHUTDOWN_FUNCTION() or perhaps, the creation of a related new
function.
Currently when a page goes to timeout, all buffers get flushed, and all
headers get sent. In the interest of handling timeouts better; it would
be ** GREAT ** if instead of all this flushing and finalization occuring,
if one could also choose to not have the current script flush and
finalize; but to remain in the script as if no timeout occurred at all.
This way, when a timeout occurs one can (for example) do redirects, or
choose to manually flush and clear buffers, allowing for cleaner INCLUDE
implimentations, and so on.
I'm thinking something like the following could be implimented:
set_time_limit(300, true);
Where 'true' means; don't end script; just kick event off stating that
timeout has occurred; allowing register_shutdown_function() to be called,
if defined... and continuing normal operation of script.
void set_time_limit ( int seconds, [bool: event notify only]); default =
false.
// code example:
<?
set_time_limit(300, true);
define("NORMAL", 0);
define("ABORTED", 1);
define("TIMEOUT", 2);
function onShutdownEvent() {
switch(connection_status()) {
case NORMAL:
// code normal exit.
break;
case ABORTED:
// code aborted exit.
break;
case TIMEOUT:
header("location: http://timeout.php";);
exit;
break;
}
}
register_shutdown_function('onShutdownEvent');
while(1);
?>
Another example of the TIMEOUT switch might be:
case TIMEOUT:
while(ob_get_level) ob_end_clean();
if($dblink) mysql_close($dblink);
include('./header.html');
include('error.php');
include('./footer.html');
exit;
break;
Thanks,
Jason
