Board Optimization - datastore cache to XCache - boost your vBulletin

中文用户讨论@vbulletin-china.cn

(note: do not apply this patch on vBulletin 3.7 as it's included already)
This patch allow you to use XCache as a datastore cache in vBulletin. This is definitely your choice if you have installed and enabled XCache on you server already.

Take care that this is a beta version and was not heavily tested. And i'm not familiar with vBulletin source code as i just started reading it today, but i don't have any difficulty reading it thanks to my years of php skill

Take aware that some vB plugin is not compatible with vB_datastore_*, not just vB_datastore_XCache. So, in case you find vB_datastore_XCache won't work, you'd better try datastore to file or memcache. If one of the others works but not vB_datastore_XCache, do report it to me so i can fix it.

Pre-requirement

• a working php installtion
• a working vBulletin 3.6.5 installtion
• a working XCache installtion
• set "xcache.var_size = 10M" or so in php ini

Install the modification
for those of you who can't run "patch", u may patch the file manually

• download Attachment 61372 (class_datastore_xcache.php)
• save the file as vBulletin.3.6/upload/includes/class_datastore_xcache.php
• open vBulletin.3.6/upload/includes/class_datastore.php in your favor editor
• add a line in class_datastore.php (see below)
• update upload/includes/config.php to enable it (see below)

example class_datastore.php after modification:

PHP Code:

        }
        return true;
    }
}

// add class_datastore_xcache, enable it in config.php
require_once(DIR . '/includes/class_datastore_xcache.php');

example config.php after modification:

PHP Code:


    // vB_Datastore_Filecache  - for using a cache file
// $config['Datastore']['class'] = 'vB_Datastore_Filecache';
$config['Datastore']['class'] = 'vB_Datastore_XCache';
    // vB_Datastore_Memcached - for using a Memcache server
    // It is also necessary to specify the hostname or IP address and the port the server is listening on 


Trouble Shooting
q. i have multiple vBulletin instance installed, the seems to mix data after install this plugin
a. this applies to apc too because, if you wanna fix it, try
open class_core.php, look for:
$this->prefix =& $this->registry->config['Datastore']['prefix'];
and modify to:
$this->prefix = $this->registry->config['Datastore']['prefix'] . $_SERVER['SERVER_NAME']; // or HTTP_HOST

q. Warning: unserialize() expects parameter 1 to be string, array given in $a.php on line $b
a. upgrade your plugin/hack that $a.php belongs to, e.g. vbjournal/vbgallery etc. OR open $a.php and locate at line $b, remove unserialize call, e.g.:
replace $var = unserialize($this->data);
with $var = $this->data;
be careful do not remove the whole line, just the unseralize( and )

Will this modification work if you have xcache running as a rpm?

sure, rpm won't run for you, but it will install xcache, and you run php+xcache. that's it. it doesn't matter if you install it with rpm or whatever

I get this error when trying to install this mod:

Fatal error: XCache not installed in /includes/class_datastore_xcache.php on line 34

Any idea?

Thanks,

u have to get your XCache run first.

i suppose u have installed a XCache with rpm, but u shall append php.ini with xcache.ini and update some values.

see http://xcache.lighttpd.net/wiki/Inst...AsPhpExtension

Wow I finally figured it out and installed this hack myself. No errors as my site is Super Fast!! I'm using vbulletin 3.6.8

congrats........it really works

I asked my host about xcache and this was their reply

As for installing it, I don't really recommend it. I've found it to be somewhat
buggy, and doesn't work well with ionCube, or Zend Optimizer.

as I'm running Zend, I don't want to install xcache if it's going to crash the site.
any comment is greatly appreciated.

Thanks

This is true with the previous versions of XCache, but not the current versions (to my knowledge).
