Public bug reported:
Importing nevow into python 2.6 causes the following deprecation errors
to be reported:
"""
Python 2.6.2 (release26-maint, Apr 19 2009, 01:58:18) [GCC 4.3.3] on linux2
import nevow
/usr/lib/python2.6/dist-packages/formless/annotate.py:730: DeprecationWarning:
object.__new__() takes no parameters
rv = cls = InterfaceClass.__new__(cls, name, bases, dct)
/usr/lib/python2.6/dist-packages/nevow/testutil.py:7: DeprecationWarning: The
popen2 module is deprecated. Use the subprocess module.
from popen2 import Popen3
/usr/lib/python2.6/dist-packages/nevow/guard.py:15: DeprecationWarning: the md5
module is deprecated; use hashlib instead
import md5
"""
The computer is running Jaunty 9.04 Ubuntu Desktop (Gnome) AMD-64,
upgraded from Intrepid AMD-64 desktop. Synaptic reports that the current
installed version of python-nevow is 0.9.31-4ubuntu2
If python 2.5 is used instead of 2.6, no warnings are issued.
The second and third deprecation warnings are due to simple changes in
the layout of the standard Python library which happened between 2.5 and
2.6. I'm not sure (in detail) what is causing the first warning.
Both python 2.5 and 2.6 symlink these files to
"/usr/share/pyshared/nevow". That won't work because versions 2.5 and
2.6 need slightly different versions. This will likely be a problem with
Python 3.0 as well (I haven't installed or tested it though) as it also
uses the new library layout.
