I look forward to future versions.

Interesting that the vB developers had already coded this into vB by default. You just needed to activate it in config.php really. :)

Not really. They just started adding this, but it won't work without any changes.

OK, I'm finished with the new version so far:

0.8.1 Alpha:
  • removed a relic of an old hack from dscache.txt
  • Added config_dscache.php
  • backups can be turned off now
  • you can change the directory, where the datastore_cache.php is stored now
  • Fixed a bug, that may cause unserialize-errors in the CP out of the blue
  • rebuild_dscache.php is verbosive now
Be aware, that this hack is still an Alpha and needs testing.

Erwin 01-25-2005 08:16 PM
I installed 0.8.1 - works 100%. The backups were an annoyance and I'm glad you coded it so that they disappear. :) Thanks.

In your functions.php (the hacked version) find the following:
PHP Code:
            $data_code = preg_replace('/### (start|end) /', '\' . "\\x23\\x23\\x23 \1 " . \'', $data_code);
            $datastore_cache = file_get_contents(DATASTORE_FILE_DIR . 'datastore_cache.php');

            $datastore_cache = preg_replace(
                "/### start $title ###".
                "(?:[^#]*(?:#(?!## end $title ###)[^#]*)*)".
                "### end $title ###/",
                "### start $title ###\n\$$varname = $data_code;\n### end $title ###",
                $datastore_cache
            ); 
and replace it with the following:
PHP Code:
            $data_code = str_replace(
                array(
                    '### start ',
                    '### end ',
                    '{DATA_CODE}'
                ),
                array(
                    '\' . "\\x23\\x23\\x23 start " . \'',
                    '\' . "\\x23\\x23\\x23 end " . \'',
                    '\' . "\\x7bDATA_CODE\\x7d" . \''
                ), $data_code);

            $datastore_cache = file_get_contents(DATASTORE_FILE_DIR . 'datastore_cache.php');

            $datastore_cache = preg_replace(
                "/### start $title ###".
                "(?:[^#]*(?:#(?!## end $title ###)[^#]*)*)".
                "### end $title ###/",
                "### start $title ###\n\$$varname = {DATA_CODE};\n### end $title ###",
                $datastore_cache
            );
            $datastore_cache = str_replace('{DATA_CODE}', $data_code, $datastore_cache); 
That should do the trick.

Hmm ... why don't you just write the variables without comments?
I think this could make it easier :)

I think I will wait until the serialise bug is fixed...I have destroyed my forums twice now trying to implement this...it also doesn't seem to play nicely with Ushop.

Good idea though, and thanks for the help. :)

This hack works but I've uninstalled it :). It was really annoying to have to keep manually updating the datastore on each of my separate web servers. The crunch came when I put my forums offline to do a backup, but as I did not update the datastore manually, members could still access the forums, causing my 15 Gb database to become corrupted. :) Took me 28 hours to fix it manually as I didn't want to lose even 1 day of data. There is a slight page loading improvement, but I'd rather have the convenience.

Stadler 01-27-2005 08:54 PM
Well yeah, if you're running this on a multi server setup, you need to synchronize everything on the fly and I suppose, that setting up such a system can be a lot of work, I guess.
