[Zodb-checkins] SVN: ZODB/trunk/src/CHANGES.txt - Added support for wrapper storages that transform pickle data.

[Jim Fulton]

Log message for revision 112463:
  - Added support for wrapper storages that transform pickle data.
    Applications for this include compression and encryption.  An
    example wrapper storage implementation, ZODB.tests.hexstorage, was
    included for testing.
  
  It is important that storage implementations not assume that
    storages contain pickles.  Renamed IStorageDB to IStorageWrapper and
    expanded it to provide methods for transforming and untransforming
    data records.  Storages implementations should use these methods to
    get pickle data from stored records.
  
  - Deprecated ZODB.interfaces.StorageStopIteration.  Storage
    iterator implementations should just raise StopIteration, which
    means they can now be implemented as generators.
