Initial Comment: I write C++ applications which embed python interpreter as script engine. And I would like to perform traceback analysis during error handling (imagine for instance that I would like to include python traceback info inside some exception which will be handled outside library I write, maybe by sending error description to log server via network) What I found? PyErr_Fetch gets traceback object and gives it to me. There are methods which print traceback to standard error. But if I want to do something different ... there is no way to analyze traceback without utilizing some dirty tricks. Two main problems: - struct tracebackobject is not present in python headers, it is only in traceback.c - it is of course not documented at all. I finally managed to do what I wanted by copying tracebackobject definition from traceback.c and by copying tb_printinternal and suiting it to my needs. But what will happen if you change this structure some time in the future? What exactly do I request? Choose one of the two: 1) Either publish struct tracebackobject inside some Python headers (traceback.h?), mention in PyErr_Fetch documentation that the last parameter is of this type and describe its structure somewhere in python-embed 2) Or keep it secret but add some API which would allow to navigate traceback without presenting its internals, say the function like PyTrace_AnalyzeTraceBack which - given traceback object - would return file, line, name and next traceback (or the flag telling that there is no more). ---------------------------------------------------------------------- You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=105470&aid=497067&group_id=5470
