      Description

      If you have a struct like:

      struct test_struct {
      1:string test_string
      }

      and then in a c++ client you do:

      test_struct foo;
      client.someFunc(foo)

      then the server will see it's argument (arg) as having arg.__isset.test_string set to true.

      similarly from the client side if expect a return value and do:

      test_struct returnVal;
      client.someFunc(returnVal);

      and the server does not set the returnVal to anything it will still see returnVal.__isset.test_string as true

      in all cases the string is set to the empty string as the constuctor for test_struct sets it, but __isset should not be true.

      Attached (should be) a simple test case. Just untar run "thrift --gen cpp isset.thrift" and then run make. start up the server and run the client to see the output.
