Mario Emmenlauer updated THRIFT-4819:
-------------------------------------
Description:
In recent versions of thrift we can not exceptions based on their IDL type
anymore. I'm not sure if we broke something, but the code is sufficiently
simple to suggest a but in thrift. So here is what we have:
# A method with signature that can throw a specific exception, i.e.
UserException
# The C++ server throws this exception whenever the method is called
# The C++ client tries to catch this exception but it passes through
The client can catch the exception as `TException` or as `std::exception` and
we can see from the printed message `vException.what()` that its a
`UserException`. But catch does not deduce the type correctly.
Here is the part of the catch that does not work:
{code}
try{
vClient->SendRequest();
} catch (const MyService::UserException& vEx) {
// TODO why is this not caught????????
std::cerr << "Caught a UserException" << vEx.what() << std::endl;
} catch (const std::exception& vEx) {
std::cerr << "Caught a std::exception, message " << vEx.what() << std::endl;
}
{code}
