Summary: python -U breaks import with 2.1
Initial Comment:
python -U under Windows is broken with Python 2.1:
D:\>python
Python 2.1 (#15, Apr 16 2001, 18:25:49) [MSC 32 bit
(Intel)] on win32
Type "copyright", "credits" or "license" for more
information.
>>> import urllib
>>>
^C
D:\>python -U
Python 2.1 (#15, Apr 16 2001, 18:25:49) [MSC 32 bit
(Intel)] on win32
Type "copyright", "credits" or "license" for more
information.
>>> import urllib
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ImportError: No module named urllib

Changed Group from Platform-Specific (since it's got
nothing to do with Windows specifically) to Feature Request
(since nobody believes it *should* work now).

Martin, see email to Python-Dev: best I can tell, nobody
expects -U to work yet.

The (first) problem appears to be in string.py, which has
_idmap = ''
for i in range(256): _idmap = _idmap + chr(i)
With -U, _idmap is a unicode string, and adding chr(128)
to it will give an ASCII decoding error. Therefore,
importing string fails. In turn, many other things fail as
well.
That can be solved by writing
_idmap=str('')
but then it will still complain that distutils.util cannot
be imported in site. One problem may be that site.py
changes the strings of sys.path into Unicode strings. In
fact, when starting Python with -U -S, it will properly
locate urllib.

Assigned to Marc-Andre. M-A, do you expect -U to be useful
at this point? I thought I saw docs at one point, but
can't seem to find them again ...
