 Bug Type:         IIS related
 Operating System: Windows 2003 Server
 PHP Version:      5.0.2
 New Comment:

I am having the same problem on SuSE Linux 9.3 running Linux
2.6.11.4-21.9-default, Apache 2.0.53 and PHP 4.3.10 (cli) (built: Aug
31 2005 16:14:46)

The script below can be used to recreate the problem. After I have
press the Stop button (Firefox 1.0.7) the script continues to execute
until it is killed 15 minutes later without the shutdown function being
executed.

<?
function foo() {
        exec("echo '".date("Y/m/d H:i:s")." Terminating
Status:".connection_status()."' >> /tmp/test");
}
register_shutdown_function('foo');

exec("echo '".date("Y/m/d H:i:s")." Starting' > /tmp/test");
$count=0;
while (true) {
        $count++;
        exec("echo '".date("Y/m/d H:i:s")." Running ".$count."
Status:".connection_status()."' >> /tmp/test");
}
?>

I have tried PHP 4.4.0 and 5.0.5 and latest cvs. My server is running
on Windows 2003 with IIS 6. The functions connection_aborted and
connection_status doesn't work properly too.

Description:
------------
I have seen similar bug reports for Apache2 (where the issue is still
unresolved, but none for IIS 6.0).

I have tried two different servers, and both PHP 5.02 and PHP4.39. Each
server was running Windows 2003 with IIS 6 and exhibits the same
symptons.

Connection_status reports 0, even when the stop button is pressed, and
there is no browser listening to the script output. Connection_abort
also returns false.

Reproduce code:
---------------
ignore_user_abort(???); //Tried both true and false, no difference

while (connection_status()==0) {
 sleep(1);
 echo "test\n";
 flush();
 ob_flush();

 ... //Log an "I'm still here" timestamp, for debugging
 
 if(connection_aborted()) {
  //Log a disconnection into a DB
  exit;
  }
 }
//Log a disconnection into a DB

Expected result:
----------------
When the browser window or connection is closed, I expect the script to
stop logging the "I'm still there" message every second, and terminate
execution.

Actual result:
--------------
The script continues to run, updating the timestamp every second, until
the time limit is reached. Connection_aborted, connection_status seem to
indicate the connection is still active (but it isn't - the browser is
closed, netstat confirms that there are no connections).
