tests for egw_cache_provider and not using APC for cli, if apc.enable_cli is not set
Also did some benchmarking on my Macbook (with a SSD and memcached running on localhost): Checking egw_cache_memcache: 0 checks failed, 100 iterations took 0.480 sec Checking egw_cache_apc: 0 checks failed, 100 iterations took 0.025 sec Checking egw_cache_files: 0 checks failed, 100 iterations took 0.826 sec --> APC is by a factor of 20 faster then memcached, which is double as fast compared to files on a SSD

/**
|
||||
* Class to manage caching in eGroupware.
|
||||
*
|
||||
* It allows to cache on 4 levels:
|
||||
* a) tree: for all instances/domains runining on a certain source path
|
||||
* b) instance: for all sessions on a given instance
|
||||
* c) session: for all requests of a session, same as egw_session::appsession()
|
||||
* d) request: just for this request (same as using a static variable)
|
||||
*
|
||||
* There's a get, a set and a unset method for each level: eg. getTree() or setInstance(),
|
||||
* as well as a variant allowing to specify the level as first parameter: eg. unsetCache()
|
||||
*
|
||||
* getXXX($app,$location,$callback=null,array $callback_params,$expiration=0)
|
||||
* has three optional parameters allowing to specify:
|
||||
* 3. a callback if requested data is not yes stored. In that case the callback is called
|
||||
* and it's value is stored in the cache AND retured
|
||||
* 4. parameters to pass to the callback as array, see call_user_func_array
|
||||
* 5. an expiration time in seconds to specify how long data should be cached,
|
||||
* default 0 means infinit (this time is not garantied and not supported for all levels!)
|
||||
*
|
||||
* Data is stored under an application name and a location, like egw_session::appsession().
|
||||
* In fact data stored at cache level egw_cache::SESSION, is stored in the same way as
|
||||
* egw_session::appsession() so both methods can be used with each other.
|
||||
*
|
||||
* The $app parameter should be either the app or the class name, which both are unique.
|
||||
*
|
||||
* The tree and instance wide cache uses a certain provider class, to store the data
|
||||
* eg. in memcached or if there's nothing else configured in the filesystem (eGW's temp_dir).
