[infinispan-issues] [Red Hat JIRA] (ISPN-12489) Non-transactional INVALIDATION_SYNC cache deadlock

Non-transactional INVALIDATION_SYNC cache deadlock -------------------------------------------------- Key: ISPN-12489 URL: https://issues.redhat.com/browse/ISPN-12489 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 10.1.8.Final, 11.0.5.Final, 12.0.0.Dev06 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 12.0.0.Final Non-transactional invalidation caches use the old locking scheme from Infinispan 4.x, which is prone to deadlocks: # {{put(k, v1)}} is invoked on node A and acquires lock {{k}} # {{put(k, v2)}} is invoked on node B and acquires lock {{k}} # {{A}} sends an {{InvalidateCommand(k)}} RPC to {{B}} # {{B}} sends an {{InvalidateCommand(k)}} RPC to {{A}} # The {{InvalidateCommand(k)}} from {{A}} and tries to acquire lock {{k}} on {{B}} # The {{InvalidateCommand(k)}} from {{B}} and tries to acquire lock {{k}} on {{A}} # Both {{InvalidateCommand(k)}} lock acquisitions eventually time out and release lock {{k}} on their originators.
