             Summary: [Python binding] decimal32 and decimal64 are sent byte reversed
                 Key: PROTON-1160
                 URL: https://issues.apache.org/jira/browse/PROTON-1160
             Project: Qpid Proton
          Issue Type: Bug
          Components: python-binding
            Reporter: Kim van der Riet


When sending {{decimal32}} and {{decimal64}} types to or from the Python binding, the byte order of the numbers are reversed. This does not apply to the {{decimal128}} type.

It is noteworthy that this bug was exposed by qpid-interop-test when run against the C++ binding.  In C++, these types are all based on a byte array, whereas in the Python binding, {{decimal32}} and {{decimal64}} are derived from Python types {{int}} and {{long}} respectively, while {{decimal128}} is derived from Python type {{bytes}}.

Decimal32:
{noformat}
    sent:['0x00000000', '0x40490fdb', '0xc02df854', '0xff7fffff']
received:['0x00000000', '0xdb0f4940', '0x54f82dc0', '0xffff7fff']
{noformat}

Decimal64:
{noformat}
    sent:['0x0000000000000000', '0x400921fb54442eea', '0xc005bf0a8b145fcf', '0xffefffffffffffff']
received:['0x0000000000000000', '0xea2e4454fb210940', '0xcf5f148b0abf05c0', '0xffffffffffffefff']
{noformat}
