#3 Packing of integers causing import error on python 2.7.x

[Michal Ambroz]

Hello,
import of engine.py is causing this error on python 2.7.x

error Traceback (most recent call last)

42 for i in integerstrings:

error: integer out of range for 'I' format code
--------------------------------------------------------------------------------------
This is because pack('<I', -1) throws and error on python 2.7

I have solved this by converting to unsigned first:

def unsigned(x):
if ( x < 0 ):
return unpack('<I',pack('<i',x))[0]
else:
return x

#Pack integers as strings for 32bit
integerstrings_little_endian = []
for i in integerstrings:
integerstrings_little_endian.append(pack('<I',unsigned(i)))
integerstrings_big_endian = []
for i in integerstrings:
integerstrings_big_endian.append(pack('>I',unsigned(i)))

Please could you consider adding this to the upstream package?

Thank you
