[Quickfix-users] Fwd: exception thrown in python with twisted logging
|

Hi folks,
I'm using the python binding from quickfix 1.12.4, and seeing a
possible bug in the python interface to the Application class. The
platform is CentOS 4.4 (equiv to RHEL 4, update 4).
(1)
Basically in C++, defining the method
FIX::MyApplication::onCreate(const FIX::SessionID& sessionID )
{
cout << sessionID.toString() << endl;
}
works, and prints the session ID as a string when the session is
instantiated, but under python, the code:
class MyApplication(quickfix.Application):
def onCreate(self, sessionID): print "Session ID = " + sessionID
throws an exception when called: "terminate called after throwing an
instance of 'Swig::DirectorMethodException' ". However, calling
sessionID.toString() here instead works.
(2)
In addition, in a very simple application, I'm getting more of these
Swig::DirectorMethodException' errors, and can't seem to determine
the origin.
Below I've included a simple, sample program and the gdb backtrace
from when the program puked. The error occurs in the Initiator.block()
method.
Any ideas on the cause of these errors?
thanks,
rob

storeFactory,settings, logFactory)
initiator.start()
while 1 == 1 :
time.sleep(1)
print "waiting..."
initiator.stop()
