[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2661) Second-level cache is used after Session.setCacheMode(CacheMode.IGNORE)

Anders Wallgren commented on HHH-2661:
--------------------------------------

Hmmm.  On second thought, I might be off in the weeds on this -- we still want cache coherency (for other sessions) even if this session ignores the cache.

> MySQL 5.0

> I'm doing some bulk importing and want to disable the L2 cache, so I call Session.setCacheMode(CacheMode.IGNORE) before doing any work.
> However, the entities I'm creating still end up in the cache.  It seems that org.hibernate.action.CollectionAction isn't doing the correct check to determine when to cache -- it only check for the existence of a configured cache, but doesn't check whether caching is enabled in the session.
> For example, from CollectionAction.beforeExecutions:
> 	public final void beforeExecutions() throws CacheException {
> 		// we need to obtain the lock before any actions are
> 		// executed, since this may be an inverse="true"
> 		// bidirectional association and it is one of the
> 		// earlier entity actions which actually updates
> 		// the database (this action is resposible for
> 		// second-level cache invalidation only)
> 		if ( persister.hasCache() ) {
> 			final CacheKey ck = new CacheKey( 
> 					key, 
> 					persister.getKeyType(), 
> 					persister.getRole(), 
> 					session.getEntityMode(), 
> 					session.getFactory() 
> 				);
> 			lock = persister.getCache().lock(ck, null);
> 		}
> 	}
> Shouldn't "if ( persister.hasCache() )" be persistence.hasCache && getSession.getCacheMode.isPutEnabled(), or something along those lines?
