Since bsddb isn't in py3k, this patch just goes back to using DictMixin in order to correct the regression. --- diff --git a/Lib/bsddb/dbshelve.py b/Lib/bsddb/dbshelve.py index 1706ca86f4..7c875b4738 100644 --- a/Lib/bsddb/dbshelve.py +++ b/Lib/bsddb/dbshelve.py @@ -59,16 +59,11 @@ else: return cPickle.dumps(object, bin=protocol) -if sys.version_info[0:2] <= (2, 5) : - try: - from UserDict import DictMixin - except ImportError: - # DictMixin is new in Python 2.3 - class DictMixin: pass - MutableMapping = DictMixin -else : - import collections - MutableMapping = collections.MutableMapping +try: + from UserDict import DictMixin +except ImportError: + # DictMixin is new in Python 2.3 + class DictMixin: pass #------------------------------------------------------------------------ @@ -111,7 +106,7 @@ def open(filename, flags=db.DB_CREATE, mode=0660, filetype=db.DB_HASH, class DBShelveError(db.DBError): pass -class DBShelf(MutableMapping): +class DBShelf(DictMixin): """A shelf to hold pickled objects, built upon a bsddb DB object.
