             Summary: Create a new status for when put/putIfAbsent/replace return the previous value
                 Key: ISPN-4763
                 URL: https://issues.jboss.org/browse/ISPN-4763
             Project: Infinispan
          Issue Type: Enhancement
          Components: Remote Protocols
            Reporter: Galder Zamarreño
            Assignee: Galder Zamarreño
             Fix For: 7.0.0.CR1, 7.0.0.Final


With the current protocol way of handling previous, the client needs to track the request's return previous flag value when it needs to decide whether to decode the previous value in the response or it.

Doing this ties the decoder with the request made. It would be better for the put/putIfAbsent/replace operations to provide a different status code, say 0x04 for when the operation succeeds and the previous value follows. By doing this, the decode has all it needs to decode in the actual response, rather than having to remember what the request flag was.

This can easily be fixed in Hot Rod 2.0 protocol.
