Hi,
You can re-read the thread at http://lists.ironpython.com/pipermail/users-ironpython.com/. The fastest possibility is: - Fetch the IronPython source. - Patch PythonContext.GetEqualSite yourself according to the description in the thread. - Use your own compiled version. Grüße, Markus Von: users-boun...@lists.ironpython.com [mailto:users-boun...@lists.ironpython.com] Im Auftrag von surangika ranathunga Gesendet: Dienstag, 19. April 2011 04:28 An: Discussion of IronPython; Jeff Hardy Betreff: Re: [IronPython] how to generate multiple concurrent scriptignengines? Hi, Sorry I missed the posts on this thread. This is the code that caused me the problem (I posted this in the first post of the thread) So according to your mails, I take that this is due to a bug in the ironpython code. Is there a way I can have some alternative work-out, something that I can do through my code? (i'm in kind of a hury to finish the project :S ) ScriptEngine engine = Python.CreateEngine(); ScriptRuntime runtime = engine.Runtime; ScriptScope scope = runtime.CreateScope(); ops = engine.Operations; try { ScriptSource source = engine.CreateScriptSourceFromFile("ironpython.py"); source.Execute(scope); string class_param = rule; object[] parameters = new object[1]; parameters[0] = class_param; object klass = scope.GetVariable("model_checker"); object instance = ops.Invoke(klass, parameters); method = ops.GetMember(instance, "check_model"); } catch (Exception e) { Console.WriteLine(e.ToString()); } --- On Thu, 14/4/11, Jeff Hardy <jdha...@gmail.com <mailto:jdha...@gmail.com> > wrote: From: Jeff Hardy <jdha...@gmail.com <mailto:jdha...@gmail.com> > Subject: Re: [IronPython] how to generate multiple concurrent scriptign engines?

What is the exception that you are getting?

Essentially, these engines should access the same underlying python code, and hence these scripting engines are identical to each other. > Without any change, the above code works fine for most of the time for a multi-threaded application.
