Bug no such file - /dbtech/vboptimise_pro/includes/cachers/cacher_datastore.php ?

[eva2000]

Hi guys been a while since I popped in here. This is actually a question on behalf of a client of mine who I referred to you guys for purchasing pro license + branding free

He's having some load issues which I am diagnosing and while stracing his PHP proceses, I noticed a call to a none exist file in vB Optimise Pro

vB Optimise Pro 2.5.3

non existent file in /dbtech/vboptimise_pro

ls -lah /home/username/public_html/forum/dbtech/vboptimise_pro/includes/cachers/cacher_datastore.php

/bin/ls: /home/username/public_html/forum/dbtech/vboptimise_pro/includes/cachers/cacher_datastore.php: No such file or directory

but it exists in /dbtech/vboptimise non-pro directory

ls -lah /home/username/public_html/forum/dbtech/vboptimise/includes/cachers/cacher_datastore.php    

-rw-r--r-- 1 username username 909 Jun 18 01:43 /home/username/public_html/forum/dbtech/vboptimise/includes/cachers/cacher_datastore.php

Checked vB Optimise Pro 2.6.0b2 and same no file in vboptimise_pro directory, so before I get the client to update his vB Optimise Pro version, is there anything that would result in looking for that non-existent file ?

Looks like there's a few more too

4090  1377608401.741653 lstat("/home/username/public_html/forum/dbtech/vboptimise_pro/includes/operators/memcache.php", 0x7fffa351bd30) = -1 ENOENT (No such file or directory) <0.000236>
4090  1377608401.742334 lstat("/home/username/public_html/forum/dbtech/vboptimise_pro/includes/operators", 0x7fffa351bb60) = -1 ENOENT (No such file or directory) <0.000145>
4090  1377608401.746151 lstat("/home/username/public_html/forum/dbtech/vboptimise_pro/includes/operators/memcache.php", 0x7fffa351bd40) = -1 ENOENT (No such file or directory) <0.000224>

which also don't exist at /home/username/public_html/forum/dbtech/vboptimise_pro but do exist off /home/username/public_html/forum/dbtech/vboptimise ?

Assuming lstat is at the source of file_exists() in PHP then the reason is the following block of code:

		if (!file_exists(DIR . '/dbtech/vboptimise_pro/includes/cachers/cacher_' . $what . '.php'))
		{
			if (file_exists(DIR . '/dbtech/vboptimise/includes/cachers/cacher_' . $what . '.php'))
			{
				require_once(DIR . '/dbtech/vboptimise/includes/cachers/cacher_' . $what . '.php');
			}
			else
			{
				self::report('Unable to assign cacher (' . $what . '). vB Optimise disabled.');
				$vbulletin->options['vbo_online'] = false;
				return false;
			}
		}
		else
		{
			require_once(DIR . '/dbtech/vboptimise_pro/includes/cachers/cacher_' . $what . '.php');
		}

In other words it's completely normal
