[Quickfix-developers] Sending 141=Y

[Ajay K. <Aja...@tr...>]

It seems to me that there is a problem in consistently sending 141=3DY =
in
a Logon even when ResetOnLogout, ResetOnDisconnect, and
SendResetSeqNumFlag are all set to Y for a session.=20

When using FIX4.1 and higher, QuickFix decides to set 141=3DY when
initiating a Logon  if
1. one of the session config attributes ResetOnLogout,
ResetOnDisconnect, or SendResetSeqNumFlag is set to Y
2. and if the expected sender and target sequence numbers are equal to 1
=20
When ResetOnLogout and ResetOnDisconnect are set, QuickFix will reset
the sequence numbers to 1 upon a graceful session logout or abrupt
disconnect, the above conditions will be satisfied, and the next Logon
message will contain 141=3DY. However, if the engine process were to =
crash
for whatever reason, the sequence numbers will NOT be equal to 1 because
QuickFix never got the opportunity to reset the sequence numbers. Hence
when the initiator sends a Logon after the process is restarted, its
Logon will not contain 141=3DY even though all the necessary =
configuration
attributes are set correctly.

From a logical perspective, IMHO in this case it should not make any
difference whether a connection to a counter party was broken because of
a Logout, socket disconnect, or engine crash. Any ideas how to make
QuickFix consistently send 141=3DY with the out of the box configuration
attributes without having to add additional logic in the application?
