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... ;)

[Zachery]

Isn't eAccelerator a continued work of mmcache?

[digitalpoint]

Yep... MMCache is no longer developed (last release was November, 2003). eAccelerator (http://eaccelerator.net/HomeUk) 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. :)

I did the same on my installation a few days ago and it has been working flawlessly :)

Quick note for people using eAccelerator as a datastore. I forgot eAccelerator doesn't work from the shell, so a couple custom processes I have that run from the shell (using the vBulletin architecture) were failing because vBulletin will halt if the eaccelerator_get function doesn't exist. So I changed the line in my config to this:


if (!$_SERVER['argc']) $config['Misc']['datastore'] = 'vB_Datastore_eAccelerator';

Alright, I use eaccelerator - I added that class, put in the codeblock from DP into my config file - it seems to be working as I'm showing cached keys in eaccelerator.php now.

However, I'm confused about what this is doing besides what EAC normally does - anyone care to break it down real quick?

Thanks :)

Basicly its putting the vBulletin datastore directly into cache for direct access via memory, instead of having to be accessed from the database more often.

Gotcha, thanks.. Less DB hits = star in my book.

I just tried turning this on after following the instructions and my board won't load. I get the following php errors.

\board\includes\datastore_cache.php on line 4523[01-Aug-2005 11:04:11] PHP Warning: Unexpected character in input: '\' (ASCII=92) state=1 in \board\includes\datastore_cache.php on line 4523[01-Aug-2005 11:04:11] PHP Parse error: parse error, expecting `')'' in \board\includes\datastore_cache.php on line 4523
