One of the changes in Python 3.5's traceback functionality broke existing code compared to Python 3.4 by injecting an extra stack frame into the list when using traceback.extract_stack:
What this looks like on Python 3.5:
pyramid/tests/test_config/test_init.py 1108 includeme2 config.add_view(view2)
pyramid/util.py 526 wrapper return wrapped(self, *arg, **defaults)
pyramid/util.py 557 wrapper f = traceback.extract_stack(limit=4)
/Users/xistence/.pyenv/versions/3.5.0/lib/python3.5/traceback.py 201 extract_stack stack = StackSummary.extract(walk_stack(f), limit=limit)
What it used to look like on Python 3.4:
pyramid/config/__init__.py 798 include c(configurator)
pyramid/tests/test_config/test_init.py 1108 includeme2 config.add_view(view2)
pyramid/util.py 526 wrapper return wrapped(self, *arg, **defaults)
pyramid/util.py 557 wrapper f = traceback.extract_stack(limit=4)
Notice that in the Python 3.5 version:
/Users/xistence/.pyenv/versions/3.5.0/lib/python3.5/traceback.py 201 extract_stack stack = StackSummary.extract(walk_stack(f), limit=limit)
Is added.
