In addition to the above, I'd like to suggest that: - - ``zodbpickle`` should provide a "class Native(str)" type to help in straddling and live conversion. This Native type would be the result of unpickling "STRING" codes, and behave as specified in: https://github.com/zopefoundation/ZODB/wiki/Pickles#explicit-but-transitional-native-string-for-python-3 > > > Tres. > - -- > =================================================================== > Tres Seaver +1 540-429-0999 tsea...@palladion.com > Palladion Software "Excellence by Design" http://palladion.com > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.11 (GNU/Linux) > Comment: Using GnuPG with undefined - http://www.enigmail.net/ > > iEYEARECAAYFAlFttq4ACgkQ+gerLs4ltQ5fswCeLcPj7QROXzlXazJIuK/nAAf6 > YzkAnj07aERlQhZInv+lFWvQjqJnciZ8 > =PLZq > -----END PGP SIGNATURE----- > > _______________________________________________ > For more information about ZODB, see http://zodb.org/ > > ZODB-Dev mailing list - ZODB-Dev@zope.org > https://mail.zope.org/mailman/listinfo/zodb-dev _______________________________________________ For more information about ZODB, see http://zodb.org/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
