[C++-sig] Python exception traceback infomation in C++
I call my C++ extension from python and the C++ code in turn calls back into python code. When the python callbacks raise exceptions I can't easily find out the tracebacks, they stop short at the C++ interface. I might put decorators on all my python callbacks to log the tracebacks. Is there any better way to do this failing an extension of boost.python to propagate this information through the C++ layer? Did anything ever happen with the discussion in this thread? http://thread.gmane.org/gmane.comp.python.c++/12693/focus=12701 Regards, John. ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
