Description
Python representations of:
- proton.ubyte
- proton.ushort
- proton.uint
- proton.ulong
can hold a negative value, even though they should be unsigned
import proton
print proton.ubyte(-1)
print proton.ushort(-1)
print proton.uint(-1)
print proton.ulong(-1)
results in
-1 -1 -1 -1
I would expect for unsigned type when negative value is supplied either TypeError or positive supplement, but latter will cause ambiguity.
with real example trying to send such negative unsigned value, proton produces internal error
