Re: [infinispan-dev] StressTest: why removals are not working as expected

I've replicated this in https://svn.jboss.org/repos/infinispan/trunk/core/src/test/java/org/infin... When we call getFirstNonOwner("k1").put("k1", "value"); apart from replicating k1 to the owners of k1, it also resides in the non owner. So, when we call getOwners("k1")[0].remove("k1");, it will only remove it from those nodes where k1 is owner. The end result is that a non-owner ends up with k1. The fix for this does not seem trivial: You either, avoid non-owners storing data in the cache if DIST and !L1, or when !L1, do a cluster wide removal. The first option looks to be more correct one. If I don't have an L1 and I'm not the owner of k1, why should I keep it at all? Maybe this could be implemented via a Flag, i.e. Flag.SKIP_CACHE (you'd probably need to use Flag.SKIP_CACHE_STORE too to avoid putting in the cache store). With the second option, you'd have to start figuring out which other ops would need to be executed cluster wide regardless of ownership when L1 is disabled. More prone to errors IMO.
