> Key: PROTON-2038
> URL: https://issues.apache.org/jira/browse/PROTON-2038
> Project: Qpid Proton
> Issue Type: Bug
> Components: python-binding
> Reporter: Kim van der Riet
> Assignee: Kim van der Riet
> Priority: Major
>
> 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}}
> If an unsigned type containing a negative value is used in a message in any context, it can cause an Overflow exception to be thrown within Proton.
