Re: [infinispan-dev] Merged and MergeEvent in 4.2

Well spotted! I took a look at other listeners, looks good. Right now, when a merge happens are the ViewChange listeners going to be notified or do we have to explicitly register for both events? IMO MergeEvent is an ViewChange, and all the listeners that registered for ViewChange should be notified whenever a merge takes place. wdyt? Enjoy the long weekend!

I believe this is how it used to be before the ViewChangeEvent and MergeEvent split in 4.2. I made MergeEvent extend ViewChangeEvent, therefore all we had to do is to attach @Merged to already existing listeners. I have verified handling of merge for DistributionManager. I also enabled rehashing test under merge scenario. It now passes. There were no other regressions on test suite. > > Will you (if you are familiar) have a look at SingletoStore, KeyAffinityService and TransactionTable? > The relevant change set is http://fisheye.jboss.org/changelog/Infinispan/?cs=2496 > > Talk to you guys Tuesday (Long weekend in Canada:)), > Vladimir > > > > On 2010-10-08, at 10:23 AM, Vladimir Blagojevic wrote: > >> Wherever we used to listen for ViewChangeEvents we now have to listen for MergeEvents as well, don't we? I've looked around and I believe that there are four internal areas of our codebase that need to adapt to these changes: KeyAffinityService, DistributionManager, SingletonStore and TransactionTable. I'll handle DsitributionManager, and the others, if you are familiar with the codebase please have a look and talk to me privately so we can coordinate further. >> >> Regards, >> Vladimir >> >> >> On 2010-10-07, at 10:47 AM, Vladimir Blagojevic wrote: >> >>> Good point.

I see that Manik added Merged annotation and MergeEvent in 4.2 which are similar to ViewChanged annotation and ViewChangedEvent except that they are exclusively used for merge view notifications. Anyway, JGroups MergeView is detected in JGroupsTransport, listeners are invoked except that Merge notification is not allowed to propagate in CacheManagerNotifierImpl! In addition to this DistributionManagerImpl does not register listener for Merge event notification! >>>>> >>>>> Does anyone know what is going on here?
