Looks like you are doing two async operations together in your server: (in
calldata when status == PROCESS)
* responder_.Write (reply_, this);*
* responder_.Finish(grpc::Status::OK, this);*
Instead try one operation at a time..For example, add a new state (for
example: DESTROY) and you can modify the CallData's Process() function the
following way:
enum CallStatus { CREATE, PROCESS, FINISH, DESTROY };
void Proceed() {
if (status_ == CREATE) {
status_ = PROCESS;
service_->RequestSayHello(&ctx_, &request_, &responder_, cq_,
cq_, this);
} else if (status_ == PROCESS) {
new CallData(service_, cq_);
reply_.set_reply("hello " + request_.message());
responder_.Write (reply_, this); // Do only Write here. Not
Finish
status_ = FINISH;
} else if (status_ == FINISH) {
responder_.Finish(grpc::Status::OK, this); // Do Finish here..
Not 'delete this'
status_ = DESTROY
} else {
GPR_ASSERT(status_ == *DESTROY*);
delete this;
}
}
Let me know if that works.
thanks,
Sree
