Public bug reported:
Binary package hint: python-zodb
This is a show-stopper: ZODB no longer records attribute changes. I have
another system running Gutsy on i386, and have no problems there.
I'm attaching a code sample that gives the following output for me:
CODE:
====
from ZODB import FileStorage, DB
from BTrees.IOBTree import IOBTree
import transaction
from persistent import Persistent
class MyObj(Persistent):
def __init__(self):
self.my_attribute = "froon"
print "Making empty database"
storage = FileStorage.FileStorage('db.fs')
db = DB(storage)
conn = db.open()
root = conn.root()
print "\nstoring an object..."
root[1] = MyObj()
print "\ninspecting object..."
if hasattr(root[1], 'my_attribute') and root[1].my_attribute == 'froon':
print "object still works..."
else:
print "object is broken!"
print "\ncommitting transaction..."
transaction.commit()
print "\ninspecting object..."
if hasattr(root[1], 'my_attribute') and root[1].my_attribute == 'froon':
print "object still works..."
else:
print "object is broken!"
print "\nclosing up zodb...",
del root
conn.close()
del conn
db.close()
del db
storage.close()
del storage
print "done"
print "\nopening for another look..."
storage = FileStorage.FileStorage('db.fs')
db = DB(storage)
conn = db.open()
root = conn.root()
print "\ninspecting object..."
if hasattr(root[1], 'my_attribute') and root[1].my_attribute == 'froon':
print "object still works..."
else:
print "object is broken!"
transaction.abort()
del root
conn.close()
del conn
db.close()
del db
storage.close()
del storage
print "done"

I'm running an up-to-date Gutsy with "no funny stuff" on x86_64.
