[Quickfix-developers] Duplicate Logout messages

[Dale W. <wil...@oc...>]

QuickFIX 1.10.2:  C++; Windows XP

I have a question about the proper sequence of messages during logout 
(and whether QuckFIX is doing "the right thing.")

This shows up during a unit test for our application.
The application is acting as an initiator
 The test is trivial:  logon, wait for the onLogon callback; then 
logout, wait for the onLogout callback

A condensed version of the log produced by this test is:

15:00:47.893000 (FIX.4.2:CLIENT->EXSIM) session->logon()
15:00:47.893000 (FIX.4.2:CLIENT->EXSIM) Application::toAdmin 
8=FIX.4.2|9=66|35=A|34=1|49=CLIENT|52=20050915-20:00:47.000|56=EXSIM|98=0|108=30|10=056|
15:00:47.908000 (FIX.4.2:CLIENT->EXSIM) Application::fromAdmin 
8=FIX.4.2|9=66|35=A|34=1|49=EXSIM|52=20050915-20:00:47.000|56=CLIENT|98=0|108=30|10=056|
15:00:47.924000 (FIX.4.2:CLIENT->EXSIM) Application::onLogon
15:00:47.924000 (FIX.4.2:CLIENT->EXSIM) session->logout()
15:00:48.033000 (FIX.4.2:CLIENT->EXSIM) Application::toAdmin 
8=FIX.4.2|9=54|35=5|34=2|49=CLIENT|52=20050915-20:00:48.000|56=EXSIM|10=018|
15:00:48.033000 (FIX.4.2:CLIENT->EXSIM) Application::onLogout
15:00:48.033000 (FIX.4.2:CLIENT->EXSIM) Application::fromAdmin 
8=FIX.4.2|9=54|35=5|34=2|49=EXSIM|52=20050915-20:00:48.000|56=CLIENT|10=018|
15:00:48.049000 (FIX.4.2:CLIENT->EXSIM) Application::toAdmin 
8=FIX.4.2|9=54|35=5|34=3|49=CLIENT|52=20050915-20:00:48.000|56=EXSIM|10=019|

Two things I see:
#1: the onLogout callback happens before the Logout reply from the 
counterparty, and
#2: an "extra" Logout message is being sent: presumably in response to 
the Logout from the counterparty.

Is this correct behavior?

PS: #1 led to an interesting race condition when we started the next 
test which managed to send a  login *before* the logout reply came from 
the counterparty, but that's another issue.
