Re: Help: pickle module unable to load rb mode files in linux
I am attaching the file which has to be read.. please take a look into it. The actual source code can be observed at https://github.com/scipy/SciPyCentral/blob/master/scipy_central/rest_comments/views.py#L235 when we use rb mode in windows, its working. but its not working in linux system (particularly CentOS) On Tue, Apr 2, 2013 at 8:50 PM, Peter Otten __pete...@web.de wrote: Surya Kasturi wrote: Hi, hope you can help me on it.. with open(pickle_f, 'r') as fhand: obj = pickle.load(fhand) This works on linux but not in windows until I use rb mode while creating file object.

Please give a complete self-contained example that uses wb to write the file and rb to read it, and that fails on Linux.

I am using Linux, but I cannot reproduce an EOFError with the attached file: Python 2.7.2+ (default, Jul 20 2012, 22:15:08) [GCC 4.6.1] on linux2 Type help, copyright, credits or license for more information. import pickle with open(index.fpickle, rb) as f: ... obj = pickle.load(f) ... obj {'body': u'pyahoo/p\n', 'prev': None, 'display_toc': False, 'title': u'lt;no titlegt;', 'sourcename': 'index.txt', 'customsidebar': None, 'current_page_name': 'index', 'next': None, 'rellinks': [('genindex', u'General Index', 'I', u'index')], 'meta': {}, 'parents': [], 'toc': u'ul class=simple\n/ul\n', 'sidebars': None, 'metatags': ''} As the data has only built-in types it cannot be a library thing either. Given that the file's location is determined dynamically [views.py] call_sphinx_to_compile(settings.SPC['comment_compile_dir']) pickle_f = ''.join([settings.SPC['comment_compile_dir'], os.sep, '_build', os.sep, 'pickle', os.sep, 'index.fpickle']) with open(pickle_f, 'rb') as fhand: obj = pickle.load(fhand) I'd add a print pickle_f statement just before the with-statement to ensure that you don't have two different pickle files, one of them being empty or otherwise broken. -- http://mail.python.org/mailman/listinfo/python-list

Surprisingly, the rb mode is not working on Linux.. raising EOFError. Just use a decorator with a pass in parameter about the OS to wrap the two versions in different platforms. By the way any function can be saved in a variable to be passed around means that the lambda 1-liner is not necessarily required in Python. In C++, the sub-classing with virtual membership function reload mechanism is the equivalent part. -- http://mail.python.org/mailman/listinfo/python-list
