Hi All, I'm implementing a tcp socket to be used with a client and server derived classes. I'm testing the code with boost test but I get the following error: "The I/O operation has been aborted because of either a thread exit or an application request" Here is the test code. std::string host = "localhost"; unsigned short port = 20001; //Server* server = new Server(); //server->acceptAsyncOnThread(port); Server server; server.acceptAsyncOnThread(port); Client client; TcpSessionPtr connection = client.connect(host, port); bool accepted = false; boost::timer timer; while (!accepted && timer.elapsed() < 1.0) { //accepted = server->hasAccepted(); accepted = server.hasAccepted(); } //delete server; BOOST_CHECK_EQUAL( accepted, true ); Can anybody please explain me the reason of that error? Moreover, do you expect that using the commented code (i.e. the Server instance is created on the heap and deleted before the BOOST_CHECK_EQUAL call) may solve the problem? Why? Regards Gianni
