GrpcServiceBridgeImpl should set exception handling callback #101

Questions

When I using GrpcServiceBridgeImpl, some of the behavior of vertx-grpc is not as expected when the network is abnormal.

Expect Behavior

void init(ServerCall.Listener<Req> listener) {
this.listener = listener;
req.errorHandler(error -> {
if (error == GrpcError.CANCELLED && !closed) {
listener.onCancel();
}
});
readAdapter.init(req, new BridgeMessageDecoder<>(methodDef.getMethodDescriptor().getRequestMarshaller(), decompressor));
writeAdapter.init(req.response(), new BridgeMessageEncoder<>(methodDef.getMethodDescriptor().getResponseMarshaller(), compressor));
}

if the network between client and server was interrupted, listener.onCancel() should be invoked.

Actual Behavior

nothing happened.

Version

4.5.7


The errorHandler is an method from GrpcReadStream, it was invoked only when the httpStream has a StreamResetException, but when client was killed, an IOException occurred.

public void init() {
stream.handler(this);
stream.endHandler(v -> queue.write(END_SENTINEL));
stream.exceptionHandler(err -> {
if (err instanceof StreamResetException) {
handleReset(((StreamResetException)err).getCode());
} else {
handleException(err);
}
});
queue.drainHandler(v -> stream.resume());
