[ZOOKEEPER-555] Add stat information to GetChildrenResponse

• Type: Improvement
• Status: Closed
• Priority: Minor
• Resolution: Fixed
• Affects Version/s: 3.3.0
• Fix Version/s: 3.3.0
• Component/s: c client, contrib-bindings, java client, server
• Hadoop Flags: Incompatible change, Reviewed

Release Note

This change is backward incompatible with server versions prior to 3.3.0 given that the wire protocol has changed. However at the client API level this is a b/w compatible change (added new api methods).

Changes required to have Stat returned with get_children().

Description

GetChildren() is the only non-create/delete API which does not include the node stat information. I propose that the definition of GetChildren() should be:

class GetChildrenResponse

{ vector<ustring> children; org.apache.zookeeper.data.Stat stat; }

There is a trivial fix to the server (FinalRequestProcessor.java): rsp = new GetChildrenResponse(children, stat);

And something similar to the client library.
