Summary: bsddb/weakref error

Initial Comment:
After a cvs up and reinstall of Python, Spambayes is giving 
me this traceback:

Traceback (most recent call last):
  File "/Users/skip/local/bin/sb_filter.py", line 257, in ?
    main()
  File "/Users/skip/local/bin/sb_filter.py", line 248, in main

    self.h = hammie.open(self.dbname, self.usedb, 
self.mode)

    self.dbm = dbmstorage.open(self.db_name, self.mode)
  File "/Users/skip/local/lib/python2.4/site-packages/

    return f(db_name, mode)
  File "/Users/skip/local/lib/python2.4/site-packages/

    import bsddb
  File "/Users/skip/local/lib/python2.4/bsddb/__init__.py", 
line 68, in ?
    exec """
  File "<string>", line 3, in ?
  File "/Users/skip/local/lib/python2.4/weakref.py", line 152, 
in ?
    class KeyedRef(ref):

instances

I don't know what it means, but it wasn't happening before 
the cvs up.  I suspect something changed in the bsddb3 
stuff, so I'm provisionally giving it to Greg.

Have we worked out how Skip has hosed his install yet <wink>?  
IOW, if there's no evidence of a Python bug (and IMO there isn't) 
we should close this.

What version of Spambayes are you using?

Is there a Spambayes test suite I can run with a given
Python, without screwing with my own Spambayes installation?
 I don't know anything about Spambayes development.

Is this running on Mac OS X of some flavor?  (Guessing from
the weird /Users directory.)

mwh's comment is right on target; something fishy is going
on here.  It looks like you're getting the CVS version of
weakref.py, but you _weakref.so is out of date.

Yes.  My sandbox has no tags.  I generally just blindly do a
"cvs up ; configure ; make install" and start using the
result as my day-to-day Python interpreter.

I just reverted Fred's changes from July 2 to the relevant
.c, .py and .h files in my sandbox and confirmed that the
traceback disappeared.

Maybe there's nothing wrong with what Fred checked in, but
that it had an unintended effect on the bsddb package, and
that's where the problem needs to be resolved.

Are you sure your build is completely up to date?  For
whatever reason, it looks like _weakref.ref in the traceback
above is a 'builtin_function_or_method', not a 'type' which
is what Fred's checkins turned it into.

Further inspection of recent python-checkins activity shows
a large change to the weakref stuff by Fred on July 2nd
(more recent than Greg's change to bsddb on June 28th), so
reassigning to him in case it's a weakref problem.
I've been so-far unable to back out the change in my
repository (subsequent changes to some of the files make
that difficult), so I can't verify the weakref changes are
the root of my problems, but they seem pretty wide-ranging,
so that's my guess.
