About same as problem in 2.4 Issue1470422 closed without a test case on
MacOS X/Python 2.4.
Also same as
http://mail.python.org/pipermail/python-bugs-list/2004-July/024111.html
and so on back for years.
What happens:
chasm@chasm-laptop:~/py$ cat x.py
import logging
logging.basicConfig(level=logging.DEBUG,
 
format="%(levelname)s:%(pathname)s:%(lineno)d:%(message)s")
from logging import debug
if __name__ == "__main__":
 debug("Hello")
chasm@chasm-laptop:~/py$ python x.py
DEBUG:logging/__init__.py:1327:Hello
What should happen:
It should print DEBUG: x.py:3:Hello
Why it fails:
Because logging guesses that the right sys._getframe(level) should be
level 3 in __init__.py:71, in currentFrame
if hasattr(sys, '_getframe'): currentframe = lambda: sys._getframe(3)
What should happen:
It shouldn't guess. In Python 2.5, the lambda might count. In any
case, the level is off by one (4). I suggest that it get set by walking
up the stack from until it exits the stack frame.
