4b9078eb7d fix implementation of calling (set|get|unset)Cache with install_id to behave identical to call to (set|get|unset)Instance for current instances install_id (install_id was used directly in keys) 2014-05-22 11:21:02 +00:00

01a7875627 egw_cache::(get|set|unset)Cache($level,...) excepts now an install_id to use instance cache of given instance
accounts class uses now instance_id to access instance cache to support using it with multiple instances
instanciating accounts class with an array of config values clears now internal static cache and singelton instance

189d89be1b 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

2ed73047df fixed serveral issues around cached config:
- changing config in setup did not update or unset the cache --> instance was NOT using it
- new installs failed, because cache was not configured
- cache command to not configured cache gave fatal error, now they throw a (catchable) exception

ae5cde8259 fix bug reported on devel-list:
egw_cache::get_provider(Instance) no provider found (error instanciating provider egw_cache_files: egw_cache_files::__construct() server/temp_dir
--> made egw_cache::get_config_value public, so egw_cache_files can use it and for regular egw sessions read install_id and temp_dir together with system_charset, before calling config::read()

389486793d - config is now cached on instance level
- arrays in $GLOBALS[egw_info][server] are now automatically serialized and unserialized
- new static method to check if user is export-limit excepted
--> saves to query it on each request (for non-phpgwapi, which was already cached in the session)

6865fad5c7 New caching provider using APC's shared memory cache.
Used now by default, if function apc_fetch() exists and no
other caching provide is explicitly set in header.inc.php or egw_cache
class. 
It's probably quicker on virtual machines, as it uses memory and not the
filesystem.

3ec3c205ee created a rpm post script to automatic install or update EGroupware:
- cleaned up exceptions in cli code (no need to log, as it goes direct to the user)
- regarding small rpm redirect header (< 200 bytes) as no header
- fixed wrong detected vars for cli install (eg. webserver_url)
- fixed egw_cache to not stall if system_charset is not yet in db

bf036043b2 - making all methods of translation class static
- caching the phrases in new egw_cache on Tree level
--> a good speed improvment on my devel system
- also added a global function
check_load_extension($extension,$throw=false)

fd9856ebf5 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).
