oscache is a dead project. We need to provide a caching solution with rice 2.0 since most of the caching logic has been removed with version compatibility. The only classes used by rice that depend on oscache are:


The following classes are not not used by rice and will be deleted. If these caching classes are needed in the future we can use an ehcache/Spring 3.1 solution.

MethodCacheInterceptor - not used
MethodCacheNoCopyInterceptor - not used
MethodResultsCacheMonitor - not used
MethodResultsCacheNoCopyMonitor - not used
OSCacheMonitor - not used except by other not used items
ObjectCacheOSCacheImpl - not used
PersistenceCacheMonitor - not used

Comment by Travis Schneeberger [ 17/Aug/11 ]

still need to:

[2:30:46 PM] Travis Schneeberger: I think I will then continue with the rest of the caching work on trunk which includes:

1) figure out how to test in a distributed infastructure
2) switch from java.util.concurrent to ehcache - DONE
3) remove old ohcache stuff
4) annotate all remote services with cache annotations (we will all do this)
5) create a simple mechanism to ignore cache flush calls

before I get ahead of myself though I would like to code review this stuff and review the design.....

Notes from Code Review

  • Need to determine if spring expression language is operation on arguments or return types, didn't think argument names were stored in byte code
  • Does it only work if the jar is compiled with debugging on? Need to check this!
  • http://forum.springsource.org/showthread.php?105072-Cache-Abstraction-IllegalArgumentException-when-debug-symbols-off
  • Need to create a KRDOC jira so that we document that you must compile with debug symbols turned on for rice to work properly
  • Travis - it's spring's fault!
  • CacheProxy is only added if the interface (or one of it's parents) is actually using the Cachable interface
  • Eric - we need at least certain cache messages to go out asap after a transaction has committed
  • KSB currently has a way to queue up messages for a single transaction
  • could have different cache consistency settings, but how to configure those?
  • For now, let's implement a custom transaction synchronization for caching
  • @Travis - look at MessageSender and MessageSendingTransactionSynchronization
  • Unfortunately, can't have more than one "key" for eviction
  • right now you can only tell it to evict all entries
  • EHCache should not be a compile time dependency
  • see if we can specify this via the maven enforcer

KULRICE-5357: admin screen almost done

Comment by Travis Schneeberger [ 13/Sep/11 ]

There are a couple of improvements that could be made to the cache admin screen:

1) Not flushing individual Caches if the parent CacheManager is selected
2) Having a select all to select all CacheManagers

Unless you feel these are priorities I'll close out this jira.

I'll create a separate jira to create the proper kim permissions for this screen. I would guess this will have to be done for all the new screens in rice.
