RE: [Quickfix-developers] BodyLength or CheckSum missing

[Brian E. <Br...@ma...>]

Today I received some messages which raises a BodyLength/CheckSum error, and
I have some additional logging.

Here's a section of my log:

20031027-15:00:53 : BodyLength or CheckSum missing
20031027-15:00:53 : InvalidMessage caught in SocketConnection::read.
BodyLength or CheckSum missing The message is: ''

In SocketConnection::read I added this handler:

  catch ( InvalidMessage& e)
  {
		std::string errmsg("InvalidMessage caught in
SocketConnection::read.  ");
		errmsg += e.what();
		errmsg += " The message is: '";
		errmsg += msg;
		errmsg += "'";
		m_pSession->getLog()->onEvent( errmsg );
		std::cout << errmsg << std::endl;
    if ( !m_pSession->isLoggedOn() )
      s.getMonitor().drop( m_socket );
  }

So, within SocketConnection::read, I am getting an empty message.  I'm not
quite sure where this is coming from, but my message store shows several
areas of empty lines.

One possible cause might be in 'SocketConnection::readMessage'

  try
  {
    return m_parser.readFixMessage( msg );
  }
  catch ( MessageParseError& ) {}
  return true;

It would seem to me that this should return 'false' if an error is handled.

I seem to only get this error when there is high message volume occuring.
I'm not sure if this is related to QuickFix or the venue that I'm connecting
to.

Do yo have an example of a message that causes this error?

I seem to be having a problem where I get an InvalidMessage("BodyLength or
CheckSum missing") exception thrown from Message::validate().  When I look
at my logs, or even re-parse the message, everything is in tact.  I can't
see any reason why this exception is being thrown.  I only get this with one
venue, and it only happens every couple of days or so.  Has anyone else had
this problem before?

I've added some more logging to this area, and I think I will figure it out
soon.  The item that concerns me more is that this exception does not get
handled, and the EH eventually calls terminate() or abort() and the program
ends.  I'm using version 1.6, and I have two suggestions.

1)  "bool SocketConnection::read( SocketAcceptor& a, SocketServer& s )" has
an exception handler, while bool "SocketConnection::read( SocketConnector& s
)" does not.  My exception occurs in the latter case.  I copied the
exception code from the one read to the other to make them consistent.

2)  I added try {} catch(...) statement to the onStart() procedures, to trap
any unhanded exceptions.   I'd rather have the thread safely terminate than
for my whole app to end.   

If these changes are worthwhile, I'll try to merge them in CVS.
