[infinispan-issues] [JBoss JIRA] (ISPN-10240) Explicitly disallow concurrent operations in the same transaction

Dan Berindei created ISPN-10240: ----------------------------------- Summary: Explicitly disallow concurrent operations in the same transaction Key: ISPN-10240 URL: https://issues.jboss.org/browse/ISPN-10240 Project: Infinispan Issue Type: Enhancement Components: Core Affects Versions: 9.4.14.Final, 10.0.0.Beta3 Reporter: Dan Berindei Assignee: Dan Berindei Fix For: 10.0.0.Final Invoking multiple cache operations in parallel in the same transaction is inherently dangerous, especially when they touch the same keys (e.g. if one of them is a bulk operation). Invoking multiple cache operations in parallel became much more easier when we added asynchronous operations, and while we "know" it's not ok to access the same transaction in parallel, there is no explicit guard against it. {{AbstractCacheTransaction.lookedUpEntries}} is a {{HashMap}}, which will sometimes throw a {{ConcurrentModificationException}}, but most of the time the exception is something completely unrelated, making the problem even harder to trace back to its cause (e.g. ISPN-10239). -- This message was sent by Atlassian Jira (v7.12.1#712002)
