[asio-users] async_connect calling handler befor connect completed?

[Dimitri E. P. <dp...@e3...>]

Hello All,

I just started using asio  and I am having some trouble with 
async_connect and async_handshake on windows ( XP sp2 ) using asio 0.3.6 
. If I call async_handshake from the handler passed to async_connect I 
imediatelly get a 10057 ( WSAENOTCONN) error , if I sleep for a while 
and call async_handshake all is fine and Tls handshaking proceeds 
correctly. This is the code I am using:

void StunSharedSecretRequest::Start(){
  Debug::Output(LOG_INFO,"SharedSecret Connecting\n");

  try
  {
    boost::asio::ipv4::tcp::endpoint endpoint(mStunServerPort,mStunServer);
    mTlsContext = new boost::asio::ssl::context(mCmd.GetDemuxer(), 
boost::asio::ssl::context::tlsv1_client);
    mTlsSocket = new 
boost::asio::ssl::stream<boost::asio::stream_socket>(mCmd.GetDemuxer(), 
*mTlsContext);

    
mTlsSocket->lowest_layer().async_connect(endpoint,boost::bind(&StunSharedSecretRequest::ConnectCompleted,this,boost::asio::placeholders::error));
  }
  catch(...)
  {
    mCmd.Post(boost::bind(OnFailed,this));
  }
}


void StunSharedSecretRequest::ConnectCompleted(const boost::asio::error& 
error){
  static CommandWrapper* tmr = 0;
  Debug::Output(LOG_INFO,"Tls Handshake\n");

  if(!error){
    // if this is calld as is , the HandshakeCompleted handler will be 
called with a 10057 error.
   // if I step though the code and wait a few seconds before running 
the next statement, everything is fine
    
mTlsSocket->async_handshake(boost::asio::ssl::stream_base::client,boost::bind(&StunSharedSecretRequest::HandshakeCompleted, 
this,boost::asio::placeholders::error));
  }
}


It seems that the async_connect handler is being called before the 
connection is actually established. When using async_connect do I have 
to set the socket as blocking or is it done automatically? I tried using:

    boost::asio::socket_base::non_blocking_io command(false);
    mTlsSocket->lowest_layer().io_control(command);

but it didn't  work ( got an error )

any clues on what i'm doing wrong??
