If somebody could help with the above post then I'd be most grateful, it's a good solution for easing DB load.

Could you please share how you managed it? :)

2) Can I remove the admincp/rebuild....php script from the server when not needing to be used or does something require it to be there?

3) If I need to take my forums offline to change the options, then (as per above) will this corrupt my database? I'm confused about how this can be prevented as admins always need to update options/add forums etc. now and then. Do you take it offline, run the rebuild, update the options, run the rebuild, put it online and then run the rebuild again? Am a little confused ;)

Do you have a single or multiple webservers, where your forum is running on? If your forum only runs on a single werserver, theres nothing to worry about.

PS: Sorry for the late reply. I've been busy with other projects recently.

I have updated some files. I've only updated some of the documentation and no functionality so far, so you don't need to update anything. You'll only waste your time ;)

For people with PHP < 4.2.0 I've added a note, what they could do to get the hack running.

Erwin: Scott pointed me to the following: How about triggering rebuild_dscache.php on all your server with something, like
fopen('http://www01.example.com/path/to/rebuild_dscache.php?silent=1&key=SECRET');
?

PS: PHP 4.3.11RC1 and PHP 5.0.4RC1 are out: http://news.php.net/php.general/210866

editing init.php and adding the ushop datastore into the cache too. :)

SUGG: drop the config_dstore.php file and add the $dscache_dir var in the config.php

PHP Code:


		
			
define('CACHE_DATASTORE_FILE', true);

define('DATASTORE_FILE_DIR', './includes/');

$dscache_dobackup and BACKUP_DATASTORE_FILE are useless for now... would need to set it somewhere or delete it!

also, for security, isn't it suggested to NOT chmod the includes dir ?!

D'Oh, right. I removed the backups from the script but forgot to mention that, sry. I'll remove the redundant code.

However: I'm working on enabling rebuild_dscache.php for running as a shell script. You will then be able to specify a key, so the script will only run, if you call it with rebuild_dscache.php?k=sdiztgejklt for example.
Or with php rebuild_dscache.php -k sdiztgejklt on your favorite shell.

Another parameter would be ?silent=1 or -s to make the script silent, except error-messages.

Ok, can anyone test the recent version?
It works fine on my test-system (commandline and through URI)

Changes:
0.8.3 Alpha:

Removed some relics of the old backup functionality
some changes to make it possible to run it at the commandline (see below)
Allow to specify a key in the config-file, so this script will only run if you specify the correct key (-k KEY on the commandline or ?key=KEY in the URL)
You can make the script silent by adding -s respectively ?silent=1

These are relics of the old backup functionality and won't be created anymore. I've left the note about them for users who still have old backup files in their includes-dir (or whereever they are storing their datastore_cache.php.

You should take a look at datastore_cache.php. It should contain the expanded arrays of the usergroupcache or the forumcache for example.
