[Python-Dev] python compiler (original) (raw)

Is the requirement just the construction of full tracebacks in the event of an exception? Because Cython does that right now. In the event of an exception, the Python call frames are constructed as the C call stack is unwound. I thought Maciej was suggesting that having full Python frames for any Python call was part of the semantics, which is what we only do in the case of a profiling run. I'm really not trying to belabor the point -- but if there's something Cython should be doing and isn't, it's always good to hear about it. (Feel free to point me to an appropriate section of the docs ...)

I guess being able to do inspect.currentframe() is a "SHOULD" requirement for Python implementations. It's clear that it will be difficult to provide, so portable applications SHOULD NOT rely on it working correctly.
