      HBTreeFolder2 fixes · c3450f14
      Julien Muchembled authored
      There's no magic in this patch series: it is known that HBTreeFolder2 has
      limitations about the ids that can be set without conflict, and this can't be
      fixed without causing compatibility issues with existing data.
      
      The patches contain:
      - some optimization
      - bug fixes
      - detection of id conflicts before causing data loss
      
      This will also allow us to use a newer version of ZODB. Recent BTrees failed
      on the following line of `_setOb`:
      
              if len(id_list) == 1 and not htree.has_key(None):
      
      (None is not valid key for comparison since
       ZODB commit bb5aac21277f43333d6450064dc6670c8c280e40)
      
      The long story about id conflicts is that a HBTreeFolder2 can't store 2 objects
      <A> and <A>-<B> where <A> does not contain '-', and that's the rule followed by
      _getOb/_setOb/_delOb. However:
      - Conflicts are detected by testing the type of the value, which means
        HBTreeFolder2 can't store values of the same type as the one it uses
        internally (i.e. OOBTree).
      - For performance reasons, _htree_iteritems and getTreeIdList use a stricter
        rule: they assume there can't be 2 objects <A> and <A>-<B>, regardless of the
        presence of a separator in <A>. Maybe this rule should be enforced in _setOb.
