/**
|
|
|
* Smarty Cache Handler Base for Key/Value Storage Implementations
|
|
|
- *
|
|
|
* This class implements the functionality required to use simple key/value stores
|
|
|
* for hierarchical cache groups. key/value stores like memcache or APC do not support
|
|
|
* wildcards in keys, therefore a cache group cannot be cleared like "a|*" - which
|
|
|
* is no problem to filesystem and RDBMS implementations.
|
|
|
- *
|
|
|
* This implementation is based on the concept of invalidation. While one specific cache
|
|
|
* can be identified and cleared, any range of caches cannot be identified. For this reason
|
|
|
* each level of the cache group hierarchy can have its own value in the store. These values
|
|
|
* are nothing but microtimes, telling us when a particular cache group was cleared for the
|
|
|
* last time. These keys are evaluated for every cache read to determine if the cache has
|
|
|
* been invalidated since it was created and should hence be treated as inexistent.
|
|
|
- *
|
|
|
* Although deep hierarchies are possible, they are not recommended. Try to keep your
|
|
|
* cache groups as shallow as possible. Anything up 3-5 parents should be ok. So
|
|
|
* »a|b|c« is a good depth where »a|b|c|d|e|f|g|h|i|j|k« isn't. Try to join correlating
|
|
|
* cache groups: if your cache groups look somewhat like »a|b|$page|$items|$whatever«
|
|
|
* consider using »a|b|c|$page-$items-$whatever« instead.
