Status: Feedback
Bug Type: Filesystem function related
Operating System: FreeBSD
PHP Version: 5.2.11
New Comment:
We are still trying to invent a script that reproduces the error.
The below is what we hoped would do it but it does not so it needs
further refinement.
The error occurs when "basename" is fed a filename without path and
once in several hundred the first character is missing.
And finally, it comes and goes, like this:
[27-Oct-2009 10:27:22] goes
[28-Oct-2009 00:26:55] comes
[28-Oct-2009 23:28:47] goes (summertime ends)
[30-Oct-2009 00:23:00] comes
[31-Oct-2009 11:40:10] goes
[02-Nov-2009 00:24:10] comes
[03-Nov-2009 11:34:41] goes
[04-Nov-2009 00:27:41] comes
[04-Nov-2009 11:28:55] goes
<?php
$driver='memcached';
for ($i=0;$i<500000000;$i++)
{
$driver=basename($driver);
if($driver != 'memcached') echo $driver."\n";
sleep(1);
}
echo "end\n";
?>

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Description:
------------
The platform is:
FreeBSD 7.2-STABLE #0: Thu Oct 15 07:23:17 CEST 2009
- Problem not tied to a specific version of OS or PHP
- Vanilla installation of Horde http://www.horde.org
- Identical problem present on two servers
- Problem started to occur spring 2009
- Low server load
- Intermittent
- Comes and goes at certain times during the day. Usually, the problem
will start around 11:30 CEST or 10:30 CET, last for 24h and then go away
for another 24h.
And yes, we have looked for causes for this behaviour
- Happens regardless of cache configuration in Horde, even without any
caching
- Happens regardless of cache and session settings in php.ini
- The below is an *example*
- One more user on the Horde lists have reported same problem with same
OS (FreeBSD)
Reproduce code:
---------------
function factory($driver, $params = array())
{
if (is_array($driver)) {
$app = $driver[0];
$driver = $driver[1];
}
$driver = basename($driver);
if (empty($driver) || $driver == 'none') {
return new Horde_Cache($params);
}
if (!empty($app)) {
include_once $app . '/lib/Cache/' . $driver . '.php';
} elseif (file_exists(dirname(__FILE__) . '/Cache/' . $driver .
'.php')) {
include_once dirname(__FILE__) . '/Cache/' . $driver .
'.php';
} else {
include_once 'Horde/Cache/' . $driver . '.php';
}
$class = 'Horde_Cache_' . $driver;
if (class_exists($class)) {
$cache = new $class($params);
} else {
$cache = PEAR::raiseError('Class definition of ' . $class .
' not found.');
}
return $cache;
}
Expected result:
----------------
Should return memcache.php in this case, but it could be "none.php"
(where the actual output will be "one.php")
Actual result:
