-----------------------------------
hostname in net.hpp has same problem
{noformat}
inline Try<std::string> hostname()
{
char host[512];
if (gethostname(host, sizeof(host)) < 0) {
return ErrnoError();
}
// TODO(evelinad): Add AF_UNSPEC when we will support IPv6
struct addrinfo hints = createAddrInfo(SOCK_STREAM, AF_INET, AI_CANONNAME);
struct addrinfo *result;
int error = getaddrinfo(host, NULL, &hints, &result);
if (error != 0 || result == NULL) {

}
return Error(gai_strerror(error));
}
std::string hostname = result->ai_canonname;
