[Quickfix-developers] Logging in QuickFIX

[Erich <gra...@al...>]

I've been doing some testing of QuickFIX performance and that suggests that I
might want to run QuickFIX with a logging object. Now the only way I've
found of doing this is to use the constructor for my acceptor without the
logging object. Now this is a bit clunky as if I want to be able to make
logging a configurabel option, e.g.

If (logging)
{
    FIX::ThreadSocketAcceptor acceptor(fixApp, storeFactory, settings,
logFactory);

    acceptor.start();

    ....

    accceptor.end();
}
else
{
    FIX::ThreadSocketAcceptor acceptor(fixApp, storeFactory, settings);

    acceptor.start();

   ...

   accceptor.end();
}

Is there a way of controlling this is the QuickFIX config? If I don't
specify a file log path the app exits and I haven't found any other setting
that seesm to relate to this.

No, this can't be done purely with configuration, but you could make
that code a bit cleaner doing something like (untested, might need
some casts):

   NullLogFactory null_factory;
   FileLogFactory file_factory;
   LogFactory* log_factory = logging ? &file_factory : &null_factory;
   ThreadedSocketAcceptor acceptor(fixApp, storeFactory, settings,
*log_factory);

The implementation of the (unfortunately mythical)  'NullLogFactory'
is left as an exercise for the reader :^)

That's what I was afraid of! Oh well - Thanks anyway.
