[infinispan-issues] [JBoss JIRA] (ISPN-2008) Optimistic concurrency in REST server is not using atomic operations

[ https://issues.jboss.org/browse/ISPN-2008?page=com.atlassian.jira.plugin.... ] Eugen Dück updated ISPN-2008: ----------------------------- Description: The REST server's optimistic currency control is not atomic. The sequence in e.g. a PUT request goes like this: * request.evaluatePreconditions * cache.put (if preconditions met) Which is not inside any lock (that would make it pessimistic, anyway), in other words, a race condition. This applies to the optimistic variants, i.e. requests carrying 'If-Match' or any of the other 'If-*' preconditions, of PUT, POST, and DELETE requests. was: The REST server's optimistic currency control is not atomic.
