ABSTRACT:
A system and method for facilitating a remote procedure call (RPC) using an auto-evolvable RPC interface or record type (an “RPC structure”). Each field of an auto-evolvable RPC structure includes a version number and a default value. During a negotiation process, a client and a server exchange their highest version numbers, thereby indicating their RPC capabilities to each other. A higher or more recent version number may indicate a more recent release of the application comprising the RPC. During an RPC, when the client sends a structure to the server, or vice versa, and it has a more recent version, it may omit one or more fields that are not in the recipient's version. When the server receives a structure from the client, or vice versa, and it has a more recent version, it may populate an extra field (not in the sender's version) with its default value.
