Category: Python Library Group: Platform-specific Status: Open Resolution: None Priority: 5 Private: No Submitted By: Bartlomiej Ogryczak (oneg) Assigned to: Nobody/Anonymous (nobody) Summary: cPickle can pickle, but cannot unpickle on 64bit machines Initial Comment: Seems that on 64-bit machines cPickle is able to pickle floats smaller then DBL_MIN, but it's unable to unpickle them. 64-bit machine (Solaris 10 on Sparc) Python 2.4.4 (#1, Oct 26 2006, 10:01:37) [GCC 3.3.4] on sunos5 Type "help", "copyright", "credits" or "license" for more information. >>> import cPickle >>> cPickle.dumps(1e-310) 'F9.9999999999999694e-311\n.' >>> cPickle.loads(_) Traceback (most recent call last): File "<stdin>", line 1, in ? ValueError: could not convert string to float Same thing works fine on 32-bit machine (P4 with MS Windows) Python 2.4.3 (#69, Mar 29 2006, 17:35:34) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import cPickle >>> cPickle.dumps(1e-310) 'F0\n.' >>> ---------------------------------------------------------------------- Comment By: Santiago Gala (sgala) Date: 2007-03-05 17:38 Message: Logged In: YES user_id=178886 Originator: NO FYI: it doesn't happen for me in python 2.4.3, 2.5svn and 2.6svn built on linux (x86_64) with gcc-4.1.2, so it looks compiler version or hw platform specific. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1672332&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
