-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have 10MB pickled structure generated in Python 2.7. I only use basic types (no clases) like sets, dictionaries, lists, strings, etc.
The pickle stores a lot of strings. Some of them should be "bytes", while other should be "unicode". My idea is to import ALL the strings as bytes in Python 3.2 and navigate the data structure to convert the appropiate values to unicode, in a one-time operation (I version the structure, so I can know if this conversion is already done, simply storing a new version value). But I get this error: """ Python 3.2 (r32:88445, Feb 21 2011, 13:34:07) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> f=open("file.pickle", mode="rb").read() >>> len(f) 9847316 >>> b=pickle.loads(f,encoding="latin1") Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: operation forbidden on released memoryview object """ I use the encoding "latin1" for transparent byte/unicode conversion (do not touch the values!). This seems to be a bug in Python 3.2. Any suggestion?. PS: The bytestream is protocol 2. PPS: If there is consensus that this is a real bug, I would create an issue in the tracker and try to get a minimal testcase. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ j...@jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:j...@jabber.org _/_/ _/_/ _/_/_/_/_/ . _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBTWOomplgi5GaxT1NAQLTYAP/U+eqhQ5nIJyBAqSgYwPmkH4DOlMj4JnH Jgt6okvOV0hRIXlZ7kbWI2l9OuQyUM4gAeTNDSjFaKs9Hswy26Ro6xhtjidivXDS TKw6ocRx92/eHvgsOdEZjrE0D8l0dOqodZddbXELp2DjpYs9aozzAsjTHqNZDE1L fujeTOhtUKw= =/bcO -----END PGP SIGNATURE----- _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
