Re: [Quickfix-developers] 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
