"fsrefs" tells you the OID of objects containing broken
When you have the OID (as binary value; I think
"fsrefs" tells you the hex value, then can use "hexvalue.decode('hex')"
to get it as binary), you can load the respective object
obj = connection[OID]
You get the connection from an object via "obj._p_jar".
In your case, an "OOBucket" lost some of its references
(that is an easy case -- provided it does not loose all its content).
You determine the broken keys and delete them:
for k,v in list(bucket.objectItems()):
try: v._p_changed = 0 # load the object
The case becomes very complicated, when the bucket ends
empty -- an empty bucket would make the (probably) enclosing
BTree invalid. You would need to fake something to
keep it non-empty.
if not bucket: bucket[k] = None # "k" was one of the deleted keys
