Dan Berindei created ISPN-9173: ---------------------------------- Summary: Availability mode should be updated atomically with the actual members Key: ISPN-9173 URL: https://issues.jboss.org/browse/ISPN-9173 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.3.0.Beta1 Reporter: Dan Berindei Assignee: Dan Berindei Fix For: 9.3.0.CR1 This is a follow-up on ISPN-7682, which asks for the topology itself to be updated atomically. {{LocalTopologyManagerImpl}} has additional logic to update the availability mode first when the cache becomes degraded and to update it last when the cache becomes available, which means any delay between the updates cannot cause data inconsistencies. But that logic doesn't really belong in {{LocalTopologyManagerImpl}}, and it's easy to forget it's there (and in fact we had a bug there related to the new rebalance phases). In addition, tests that want to check the cache behaviour in degraded mode and wait only for the availability mode change will fail if there's a big delay between the availability mode change. I actually hit this while testing my ISPN-8731/ISPN-7682 changes, and I had added a random delay in {{StateConsumerImpl}} before {{distributionManager.setCacheTopology()}}. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
