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.

oops, last line should be "exits the stack frames for the logging
module. This should be a once-per-program-execution event"
Hmm.. tracker should have a preview button.

Can you confirm whether this problem occurs even after deleting all .pyc
and .pyo files, including in the Python library folders and your
application folders? Also, which specific platform is this happening on?
On your installation, is the line number 1327 the last line in
logging/__init__.py?

In my installation, line 1327 is within the logging.debug() function,
specifically at the
call to apply(root.debug, (msg,)+args, kwargs)
chasm@chasm-laptop:~/py$ rm *.pyc
chasm@chasm-laptop:~/py$ python x.py
DEBUG:logging/__init__.py:1327:Hello
chasm@chasm-laptop:~/py$ uname -a
Linux chasm-laptop 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC
2008 i686 GNU/Linux
chasm@chasm-laptop:~/py$ python -V
Python 2.5.1
-and then-
chasm@chasm-laptop:/usr/lib/python2.5$ sudo rm -rf *.pyc *.pyo */*.pyc
*/*.pyo */*/*.pyc */*/*.pyo
chasm@chasm-laptop:/usr/lib/python2.5$ cd ~/py
chasm@chasm-laptop:~/py$ python x.py
DEBUG:x.py:7:Hello
chasm@chasm-laptop:~/py$
So it was somewhere in the library brunches. The uname -a translates
to "Kbuntu Gutsy". Python, and extras like pylint, coverage, and
nose, were installed via Kbuntu's package manager.

This is not a logging bug, but rather due to the circumstance that
.pyc/.pyo files do not correctly point to the source files that produced
them. There is another issue about this (#1180193) .
Closing this, as it's not a logging issue.
