Datastore Cache functional yet?

[Zero Tolerance]

Maybe i'm blind, but i can't find the option to change the datastore cache to filesystem instead of the database, i see the datastore cache php file in my includes/ directory, however all the variables are blank, so is it functional yet? And if so where would i find how to modify it.

Sorry if it's been answered already, i couldn't find anything using the search.

In config.php put

$config['Misc']['datastore'] = 'vB_Datastore_Filecache';

Other possible Classes are vB_Datastore_Turck (for stroing Datastore as shared memory using Turck MMCache) and vB_Datastore_Memcached.

Yep, i'm blind - Thanks Kirby

It is working as far as I can see, but for anyone who is trying this (not sure if this is actually 100% supported yet) You will need to chmod the file or make sure that IIS / apache has the rights to write and modifiy the file (for you windows users)

What about adding support for eAccelerator? Is same as mmturck, but with fixes and updates.

[digitalpoint]

Another request for eAccelerator support from me.

[nexialys]

or just support for Zend would be good to... actually, it's the internal PHP Memcache...

Isn't eAccelerator a continued work of mmcache?

[digitalpoint]

Yep... MMCache is no longer developed (last release was November, 2003). eAccelerator picked up where MMCache stopped being developed.

[Zachery]

Have you tried using the mmcache bit with eAccelerator?

[digitalpoint]

I haven't to be honest. I thought about it, but figured I would wait to see if someone else tries it first.

Is the only thing that needs to be added the line in the config file?

[Zachery]

Should be, I don't have a linux box as of yet to test anything out on, or I would have

[digitalpoint]

Nope...

Fatal error: Turck MMCache not installed in /includes/class_datastore.php on line 41

Just changing variable names in class_datastore.php will probably work.

mmcache_get -> eaccelerator_get
mmcache_put -> eaccelerator_put

etc etc

I went ahead and added a unique eAcclerator class to my class_datastore.php file for eAccelerator. Seems to work fine for me, so if vBulletin wants to work it into the distribution, that would be cool.
