Public bug reported:
Binary package hint: zope3
When I attempt to run Zope3 with 'devmode' enabled, I get the following
traceback in 'transcript.log':

AttributeError: 'module' object has no attribute '_create_bs_classes'
... and Zope quits.
The exception indicates that it can't find a '_create_bs_classes'
attribute, which is a part of the 'ClientForm' module:
de...@development:/var/log/zope3/sandbox$ python2.5
Python 2.5.4 (r254:67916, Apr 4 2009, 17:55:16)

Type "help", "copyright", "credits" or "license" for more information.
>>> import ClientForm
>>> ClientForm._create_bs_classes
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute '_create_bs_classes'
>>> dir(ClientForm)
['AmbiguityError', 'CheckboxControl', 'ClientForm', 'Control',
'ControlNotFoundError', 'FileControl', 'FormParser', 'HTMLForm',

'ItemCountError', 'ItemNotFoundError', 'Label', 'ListControl', 'LocateError',
'Missing', 'ParseError', 'ParseFile', 'ParseFileEx', 'ParseResponse',

'SelectControl', 'SubmitButtonControl', 'SubmitControl', 'TextControl',
'TextareaControl', 'XHTMLCompatibleFormParser', '__builtins__', '__doc__',
'__file__', '__name__', '__path__']
The function is actually in the 'ClientForm' submodule of the
'ClientForm' module:
>>> ClientForm.ClientForm._create_bs_classes
<function _create_bs_classes at 0x9a5b0d4>
The reason that the attribute is not imported into the main 'ClientForm'
module is because the main module uses a wildcard import:
from ClientForm import *
... which doesn't import attributes that begin with an underscore.
Now, this is where it gets really interesting.
The Zope3 package in Ubuntu is dependent on 'python-clientform', but the
'ClientForm' module that's imported by Zope3 that causes this error is
actually owned by the Zope3 package:
de...@development:/var/log/zope3/sandbox$ dpkg --search
/usr/lib/python2.5/site-packages/ClientForm/ClientForm.py
zope3: /usr/lib/python2.5/site-packages/ClientForm/ClientForm.py
... while the ClientForm.py in the root of the site-packages folder (a
link to /usr/share/pyshared/ClientForm.py) is owned by 'python-
clientform':
de...@development:/var/log/zope3/sandbox$ dpkg --search
/usr/share/pyshared/ClientForm.py
python-clientform: /usr/share/pyshared/ClientForm.py
So, the Zope3 package is dependent upon 'python-clientform', even though
it doesn't actually use it, and even breaks it for applications that use
the '_create_bs_classes' function (i.e. BeautifulSoup).
Incidentally, if the Zope3 package didn't provide its own 'ClientForm'
implementation and just used 'python-clientform', then this wouldn't be
a problem.
I'm using Ubuntu 9.04. Here's the package version information for
'zope3' and 'python-clientform':
de...@development:/var/log/zope3/sandbox$ apt-cache policy zope3
zope3:
Installed: 3.4.0-0ubuntu3
Candidate: 3.4.0-0ubuntu3

I'm not sure if this bug should be directly reported to the Zope team,
as I didn't have this problem using 'devmode' in Ubuntu 8.10.
