Hi all, I'm debugging a Plone site in an AMD64 laptop. When I first tried to run Zope, I got this exception:
OverflowError: signed integer is greater than maximum In the archives I encounter no solutions. This is what I could find, so I share with you all: It seems that on 64bit platforms, sys.maxint is much greater than list's insertion maximum index. I'm not sure if this a bug in python or a logical bound ---given the amount of RAM it would take to insert 9,223,372,036,854,775,807 items ;)--- Maybe a bug in the documentation, though However, Archetypes.Schema.moveField method documents the use of maxint for inserting at the end of the Schema:: maxint can be used to move the field to the last position possible >>> from sys import maxint >>> spos = schema.copy() >>> spos.moveField('a', pos=maxint) >>> spos.keys() ['b', 'c', 'a'] I have seen this usage in some products. This raises and OverflowError on 64bit platforms. The fix is simple in the code of the caller:: from sys import maxint if maxint >> 33: # Am I running on 64bits? maxint = maxint >> 33 theschema.moveField(the_name, pos=maxint) Now, the maxint variable holds an acceptable value. I think the docstring should be appended with a "Note: On 64bits platform this raises an OverflowError blah blah..." Best regards, Manuel. -- http://mail.python.org/mailman/listinfo/python-list
