James E. King, III commented on THRIFT-727:
-------------------------------------------
Are you saying that if I change the name of the variable, it does not break
backwards compatibility based on the simple fact that the variables are
enumerated, i.e. if I change {{1:string what}} to {{1:string message}}, if a
new server fills in {{message}} an older client can retrieve it through the
older {{what}} accessor that it has? If that's the case, cool...
> support native C++ language specific exception message

> Project: Thrift
> Issue Type: Improvement
> Components: C++ - Compiler
> Affects Versions: 0.2
> Environment: all

> The current exception implement requires the error message to be declared and
> referenced explicitly, especially when it's sent from server to the client.
> On client side, this error message cannot be accessed via a native API like
> exception::what() in C++.
> Example,
> {code}
> exception MyException {
> 1: i32 code;
> 2: string message;
> }
> {code}
> On client side, it can only be accessed like this,
> {code}
> try {
> server->someMethod();
> } catch (MyException &e) {
> cout << "MyException: " << e.message << endl; // this will print the
> exception message
> cout << "MyException: " << e.what() << endl; // this will print
> TException::Default
> }
> {code}
> At the same time, if TException::message_ is initialized, exception::what()
> does work when the exception is caught locally.
> It's a little confusing when to use the native method, and when to use Thrift
> exception message data member.
> It'll be really nice if all exception messages can be accessed the same way
> thru the navtive language on client side.
