Hi Chris, Thanks for that suggestion - evaluating it now. Reading between the lines, would it be fair to say that the SWIG-based plain Ruby wrapper is a toy, or a proof-of-concept more than a production tool?

But my problems begin when it comes to preparing the application for production. In particular I cannot get the program to logout of the exchange successfully.

But the application will start without complaint. Similar tests with the time passing EndTime also fail. So question 1: > > QUESTION 1: Should the time handling code work on Ruby? > > > On to part 2. I've added signal handlers and verified that they're called when the relevant signal is received. They set a global variable. The main "do-nothing" loop ejects when the variable is set. This bit works, although it seems that the Quickfix thread is a bit tenacious since the program only notices the signal after the HeartBtInt interval. > > The problem arises when I try to actually logout of the session and/or stop the initiator.

It is seriously lacking in documentation and whilst it's been fun ferreting around the source (C++ and Ruby) to get the meat of my application running, I fear these deployment issues are going to stop me actually getting the code accepted by the exchange. Is anyone using the gem to do real work, or should I dust off my C++ skills (from 1997...) and sacrifice all the meta-programming goodness that made writing the actual parse module straightforward? > > Thanks for any pointers, help, brickbats, whatever. > > Rob. > > > ------------------------------------------------------------------------------ > Monitor 25 network devices or servers for free with OpManager! > OpManager is web-based network management software that monitors > network devices and physical & virtual servers, alerts via email & sms > for fault.
