Hello.I have written a simple program that tries to open a connection to a
qpid broker.
I am using qpid 0.5 on Centos5.4 x86_64.
I have the following code :
/*
* File: main.cpp
* Author: root
*
* Created on March 2, 2010, 4:49 PM
*/
#include <stdlib.h>
#include <qpid/client/Connection.h>
#include <qpid/client/Session.h>
#include <qpid/client/SubscriptionManager.h>
#include <string>
#include <stdexcept>
using namespace std;
int main(int argc, char** argv) {
qpid::client::Connection connection;
std::cout<<"Begin"<<std::endl;
try {
connection.open("host", 5672, "user", "password");
} catch( std::exception &e) {
std::cout<<e.what()<<std::endl;
} catch(...) {
std::cout<<"errors"<<std::endl;
}
if( connection.isOpen() ) {
std::cout<<"Opened"<<std::endl;
}
std::cout<<"exit"<<std::endl;
return (EXIT_SUCCESS);
}
The problem is that if the first argument of connection.open is not a valid
host (for example an ip where there is no qpid broker) the program gets
stucked in the open() function.
This is the gdb backtrace when the host parameter is not valid. The SIGINT
signal is caused by me pressing CTRL +C .
