[ZODB-Dev] Corrupt BTree Problem

[mattkoz2003]

Somehow, along the way a BTree has become corrupt.  I don't know 
how/why - but I need to fix it.  It has been broken for a while 
(since pre-2.6).  I am now running 2.7.1 w/ ZEO (included with 
2.7.1).

Here is the problem.  When I do this:

for key in self.data.keys():
    postings.append(key)
return str(postings)

it returns all the keys, including 1063958497.  However, when I do 
this:  return self.data[1063958497], I get a KeyError.  I haven't 
been able to recatalog or export this to a zexp file for a long time 
(i need to export it).  I don't care about the data in that key --  
I would be happy to just delete it all together.  I have tried this:

1. del self.data.keys[1063958497] (doesn't work)
2. del self.data[1063958497] (returns key error)
3. (the following returns key error)
for id in self.data.keys():
   try:
      self.get_wrapped_posting(id)
   except:
      del self.data[id]
