425614 - Make use of Smarty cache

Status: VERIFIED WONTFIX

Description

[Nelson Ko [:nkoth]]

I have included a patch that allows selective use of the Smarty cache. The way to make use of it is:

1. to cache a particular page, or to display the cached page instead of a newly generated one:

Use $smarty->display("tiki.tpl",cache_id, null, time_to_live); instead of the usual $smarty->display("tiki.tpl");   e.g. $smarty->display("tiki.tpl",$page, null, 600);

2. to check if a page is cached:

"if ($smarty->is_cached('tiki.tpl', cache_id)) ...." This can then be used to simply display the cached page and to bypass any other processing. Note that in order for this to work correctly for pages that are implementing theme control (i.e. not mozkb.css), this check must be done after "include_once('tiki-section_options.php');"

3. to clear the cached page (which would be needed on page updates, etc...) 

$smarty->clear_cache('tiki.tpl', cache_id);

4. to mark an area within templates as not to be cached, e.g "monitor this page" text, use the {dynamic}content{/dynamic} block.

To implement this properly, especially for logged in users, there will be a need to use clear_cache in many situations. We need a full list of such situations.

Might want to implement a memcache wrapper instead of Smarty. Will be a bigger win.

We can do both.  Deleting the memcache reference from this bug in favor of bug 395271 which is a dupe of that part.  Smarty caching is lower priority.

morgamic says the smarty cache isn't that great.
