Bug description: flock with LOCK_NB not working
Description:
------------
If I execute two consecutive times (in different browser tabs) the
following script, LOCK_NB doesn't work. I mean, the second tab waits for
the first to finish.
Thanks in advance.
Reproduce code:
---------------
<?
$handle = fopen('c:\foo', 'w+');
if ($handle)
{
if (flock($handle, LOCK_EX + LOCK_NB))
{
echo 'locked!';
sleep(5);
}
else
{
echo 'not locked!';
}
fclose($handle);
}
?>
Expected result:
----------------
1st:
locked!
2nd:
locked!
Actual result:
--------------
1st:
locked!
2nd:
not locked!
