[Quickfix-developers] Logout reason

[Francis G. <fr...@at...>]

Here's another question on an old favorite: finding the elusive logout (or
failed login) reason.

Scenario using QF from C# with the latest files from CVS.  RequestNums are
set to 1,1, and the server is cycled only once a week.

QF initiator send a Logon request:
8=FIX.4.2
9=75
35=A
34=1
49=USER
52=20050613-20:26:19.281
56=TEST
96=passwor
d
98=0
108=30
10=136


and server responds with:
8=FIX.4.2
9=00065
35=A
49=TEST
56=USER
34=481
52=20050613-20:26:19.312
108=3
0
98=0
10=180

 
Now QF rejects the message and logs "MsgSeqNum too high, expecting 1 but
received 481" in the event log.

Question: how can I get this reject reason in fromAdmin? The client does not
'see' this rejection message so it has no idea why the login didn't work.

I added this to Session::validLogonState.  This should (I think) send the
logout reason to fromAdmin, but it doesn't.

  if ( msgType == MsgType_Logout )
    return true; 

Then I tried implementing the QuickFix.Log interface and added
public void onEvent(string @string)
{  log everything here }
but this method is never triggered.

I looked for onError but it doesn't seem to be available from C#.

What is the best way to work around this?  Arbitrarily incrementing
setNextTargetMsgSeqNum() until the login is successful is clumsy at best.

Thanks,
