[Python-Dev] LTTng-UST support for CPython (original) (raw)

Here is a working prototype for CPython to record all function call/return using LTTng-UST, a fast tracer.

However, there are few issues and questions:

I was not able to get PyTrace_EXCEPTION using "raise" or other error conditions. How can we trigger this event in Python code (PyTrace_C_EXCEPTION works)?
How could be the best way to get the full name of an object (such as package, module, class and function). Maybe it's too Java-ish, and it is better to record file/lineno instead?
On the C-API side: I did a horrible and silly function show_type() to run every Py*_Check() to determine the type of a PyObject *. What would be the sane way to do that?

Your comments are very valuable. Thanks!
