Gordon Sim commented on QPID-2452:
----------------------------------
The amqp 0-10 codec now correctly looks at the encoding of a string valued
variant in deciding which type to encode it as. By default it will send it as
vbin16 (vbin32 if too large fr that). However by setting the encoding to
"utf8", "utf16" or "iso-8859-15" the user can alter that if desired. However
the user is responsible for ensuring that the string is indeed valid for the
specified encoding. No conversion is done at present.
> Inconsistent handling on strings between C++ and Python messaging APIs
> ----------------------------------------------------------------------
>
> Key: QPID-2452
> URL: https://issues.apache.org/jira/browse/QPID-2452
> Project: Qpid
> Issue Type: Bug
> Components: C++ Client, Python Client
> Reporter: Ted Ross
> Assignee: Gordon Sim
> Fix For: 0.7
>
>
> Description of problem:
> This bug is in reference to the new messaging APIs.
> The handling of strings is different between the C++ and Python messaging
> APIs.
> The Python API assumes strings on-the-wire are UTF-8 encoded. The C++ API
> apparently uses raw, unencoded octet arrays.
> If a binary string of octets (with some octets > 0x7F), is encoded by a C++
> client and received by a Python client, the Python client will throw an
> exception.
> Version-Release number of selected component (if applicable):
> SVN revision 924529 and prior.
> How reproducible:
> 100%
> Steps to Reproduce:
> 1. Use the C++ API (qpid::messaging) to produce a map-message (using
> MapContent). One of the map entries should have a string value and should
> contain a sequence such as "!E\xf9\xf5\xdf\x89d\x011\xc0\xc8$7H\x99T"
> 2. Use the python client to receive the message.
> Actual results:
> The Python client will throw an exception when it tries to UTF8-decode the
> string.
> Expected results:
> Either Python should use raw-octet encoding or C++ should use UTF8. I expect
> the string seen by the Python receiver to be identical to that sent by the C++
> producer.
