Hi, Backporting the whole exception feature to Python 2 is not possible. Develop with Python 3!
Since the creation of Trollius, I'm trying the enhance debugging. For example, the latest release of trollius (version 1.0.4) now saves the traceback object in Future.set_exception() to be able to raise again the exception with the expected traceback. I'm working on a larger project to save the chain of coroutines as a large trabeback (stored as text) in debug mode, but for the "source traceback" (where rhe object was created), not for the exception traceback. I have a working patch on my PC. The following issue tracks the project: https://code.google.com/p/tulip/issues/detail?id=212 (The goal changed, the issue title is not correct) Victor
