safe_mode is off.

timeout.php:
<?php

register_shutdown_function("shutdown");
set_time_out(1);
while(1);

function shutdown() {
   printf ("Shutdown: %d\n", connection_status());
   if (connection_timeout()) {
      print ("Connection timeout\n");
   }
}

?>

php timeout.php gives me Shutdown: 0 instead of 2 and "Connection timeout"

That is true for php since 4.0.1

The PHP_CONNECTION_TIMEOUT flag is never turned on in zend_execute_API.c

I am not sure what "bug type" to choose...

So I change it to "Unknown/Other" for now.

I get no output at all (RH6.2 4.0.4 & NT5 php4-200101130745)

use standalone php to get the output or change the code somehow to get the result of connection_status() and connection_timeout() some other way (write to file, for example)

the point is that it seems to be impossible to check for timeout state: connection_status() and connection_timeout() both return zero while the shutdown function was definitly called due to timeout.

The example is stupid but it is short and clearly demonstartes the bug.

This is obvious. The time the shutdown function
is called, the status IS shutdown.

And the connection_timeout() function is deprecated (and
removed) as of 4.0.5

AND the status IS timeout. That is obvious too :)

It is a bit flag and it could also indicate that the connection was timeouted if only some php developer was not so lazy :)))

that is nice. The report was for 4.0.4 and the connection_timeout() was used only to make the code shorter. Change it to connection_status() and reopen the bug.

How can I determine that the script was terminated due to execution_time limit? connection_status() is not depricated yet, is it? But it still doesn't return the TIMEOUT status.

Just grep through the code... PHP_CONNECTION_TIMEOUT is defined but never used. Is it also depricated?

We should really nuke phpdoc/features/connection_handling,
or rewrite it...
