I realized that I used 2.3 for testing. under 2.4, the following snippet
runs without warnings:
import binascii
def test2(text, crc=0):
return hex((binascii.crc32(text, crc^-1)^-1)&0xffffffff)
in other words,
crc = binascii.crc32(text, crc^-1)^-1)&0xffffffff
should give the same result as larry's original CalculateCrc function.
