[New-bugs-announce] [issue21709] logging.__init__ assumes that __file__ is always set

[Marc-Andre Lemburg]

New submission from Marc-Andre Lemburg:

It is not when freezing the logging package, so any use of the logging package fails:

>>> import logging
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "<pyrun>/importlib/_bootstrap.py", line 2237, in _find_and_load
  File "<pyrun>/importlib/_bootstrap.py", line 2226, in _find_and_load_unlocked
  File "<pyrun>/importlib/_bootstrap.py", line 1200, in _load_unlocked
  File "<pyrun>/importlib/_bootstrap.py", line 1129, in _exec
  File "<pyrun>/importlib/_bootstrap.py", line 1359, in exec_module
  File "<pyrun>/logging/__init__.py", line 61, in <module>
NameError: name '__file__' is not defined

This is the code in question:

#
# _srcfile is used when walking the stack to check when we've got the first
# caller stack frame.
#
if hasattr(sys, 'frozen'): #support for py2exe
    _srcfile = "logging%s__init__%s" % (os.sep, __file__[-4:])
else:
    _srcfile = __file__
_srcfile = os.path.normcase(_srcfile)

Note the special case for py2exe. But this doesn't really help, since frozen modules don't have the __file__ attribute set - at least not when generated with Tools/freeze.

PS: This is with Python 3.4.1.
