One thing I would like to do in my extension module is add extra frames to the traceback when an extension occurs. At the moment C code is invisible to tracebacks. This is relevant when the C code makes a Python callback. For example if the following code sequence happens (time going down)
Python C A B C D E F G H If there is an exception in H then the traceback seen from A will be "B C G H". I want to get D, E and F into there as well. This is because "G H" could be called for several different reasons in the C code and adding the extra information will establish why. I couldn't find anything on the web or in the documentation to explain how to do it. I did find snippets of code doing things like PyTraceback_Here but they use a real Python frame which I don't have and don't know how to synthesize.
