Re: [Zope-dev] POSKeyError how to remove

The object is already gone. It's odd that it is in the index.
You can try deleting the object from the index and then saving the
index.  You might need to use ZODB 3.9 to do that, as I think __del__
was only recently added to file-storage indexes.

 Hi,

 Using Zope Debug Console, I used a part of the code fsrefs.py to find the
 oid's of POSKeyError:

     fs = FileStorage(path, read_only=1)
     undone = {}

     noload = {}

     for oid in fs._index.keys():
     try:
     data, serial = fs.load(oid, )
     except (KeyboardInterrupt, SystemExit):
     raise
     except POSKeyError:
     undone[oid] = 1
     except:
     if VERBOSE:
     traceback.print_exc()
     noload[oid] = 1

 This gave me one oid.Then I tried something like below :

 obj = app._p_jar[oid]

 But this gave me another POSKeyError instead :(

 Why does this happen? How can I delete this object.

 Thanks,
 Roopesh

Hi Jim,

But I am using ZODB 3.4.4 :( Are there any other options? How can I find
where this invalid object is being referenced?

Will something like packing resolve this?

Thanks,
Roopesh
