Description

Cocoa generator improvements relating to

• Server-side exception handling in the actual TProcessor implementation for the service
• Better handling of service inheritance
  • Service clients can now use the client subclass directly to invoke calls to the base service
  • Servers must only adopt the child protocol and will automatically adopt the base protocol over inheritance
  • The improvement should not break any existing service implementations
    • See the revisions for the implemented cocoa tutorial for instance
• For a better overview of the resulting gen-files after the improvements see the attached diff file

An implementation for the Thrift tutorial

• Server and client implementation based on the corresponding Python version
• Update relating to the improved handling of service inheritance
