Probably the lack of an answer is due to the fact that there isn't a really great way to do this. Here's two possible ways to pull this off:
For #1 you presumably kicked off the Python code via the hosting APIs, and therefore you know the engine that kicked it off. If you have multiple Python engines this might be tricky (if you have only one running on each thread at a time you could store it in a [ThreadStatic]). If you start getting into more complicated scenarios obviously this is going to break down quickly... For #2 you're looking at using ICallerContext. This is a bit of internal machinery that IronPython uses to flow state around for things that might need state (e.g. hiding CLR methods, locals(), exec, etc...). Off of ICallerContext there is both a SystemState and a PythonModule property. Unfortunately there's nothing that leads you directly to a PythonEngine. Instead you'd need to maintain a table of either modules->engines or SystemState (sys module) -> engines. #2 will work reliably if you control the creation of all engines in the process - the instance you go out of that it'll break down. The alternate plan here might be that having access to a SystemState and PythonModule you could already do some interesting things even though you don't have the full blown PythonEngine. It'd be interesting to hear if those are sufficient or if you really do need the engine in this case (and how horrible you think the 2 solutions are :) ). -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jason Ferrara Sent: Monday, September 18, 2006 8:48 AM To: Discussion of IronPython Subject: Re: [IronPython] What PythonEngine called my C# code?
