From: php at koterov dot ru Operating system: Windows, Linux PHP version: 5.1.6 PHP Bug Type: Filesystem function related Bug description: LOCK_NB for flock() does not work
Description:
------------
<?php
@session_write_close(); // be on the safe side
$f = fopen('/tmp/f.lck', 'a+');
var_dump(flock($f, LOCK_EX | LOCK_NB, $w));
var_dump($w);
sleep(5);
?>
When I run this script concurrently, all results are same: "bool(true)
int(0)". Seems LOCK_NB simply ignored.
P.S.
There is a lot of same bugs (e.g., http://bugs.php.net/bug.php?id=31363
etc.), but they are closed or outdated.
