It looks like this code is hosted somewhere. So who is catching the exception in this case? If it's you then you can do:
pythonEngine.GetService<ExceptionOperations>().FormatException(exception); to get a standard Python version of the stack trace. W/o doing that the .NET stack trace is basically useless. Sometimes code is interpreted which gives you no info and even when it's compiled it's usually as DynamicMethod's which don't have debugging info associated with them. If you enable debug mode though (-X:Debug from the command line or setting DebugMode on a ScriptRuntimeSetup) then you'll at least get some .py file line numbers in all the noise. But there's also lots of other frames which show up from the DLR and IronPython infrastructure which makes it confusing. If the code isn't hosted and you're getting this exception from pure Python code then it'd be a bug. One thing to watch out for is if you've done from System import * then "except Exception, e:" will give you the .NET exception object. > -----Original Message----- > From: [email protected] [mailto:users- > [email protected]] On Behalf Of Count László de Almásy > Sent: Wednesday, August 12, 2009 8:20 PM > To: Discussion of IronPython > Subject: [IronPython] help with an IPy traceback > > i'm still getting used to the tracebacks that IPy / .NET produces.
