Description:
------------
In the 5.0.4 release of PHP, the original proc_get_status bug (32210) doesn't appear to be fixed (Linux babe.fragzzhost.com 2.6.8.1 #1 SMP Tue Oct 12 08:27:04 CEST 2004 i686 i686 i386 GNU/Linux).

The "running" field now is always TRUE.

I know absolutely nothing about how this bit of code works, but I made the following change and it was fixed. Hopefully someone understands how this fluke works :)

Original code (note not as posted code)

                if (WIFSTOPPED(wstatus)) {
                        stopped = 1;
                        stopsig = WSTOPSIG(wstatus);
                }
        } else {
                running = 0;
        }
#endif


My dreadful change:
                if (WIFSTOPPED(wstatus)) {
                        stopped = 1;
                        stopsig = WSTOPSIG(wstatus);
                }
        } else {
                running = 1;
        }
#endif


I would also like to add that the original patch below doesn't appear to work correctly? Immediately after I kill the process manually with kill -9, running is FALSE as expected, but then if I sleep(2) then call proc_get_status() again, running is TRUE, and the process described isn't running.


Reproduce code:
---------------
(Best run from the command line)

$handle = proc_open("sleep 60", array(2 => array("pipe", "r")), $pipes);

$status = proc_get_status($handle);
var_dump($status["running"]);
sleep(5);

(confirmed at this stage that process is still running by 'ps aux')

system('kill -9 '.$status['pid']);
sleep(2);

$status = proc_get_status($handle);
var_dump($status["running"]);


Expected result:
----------------
bool(false)
bool(false)
