Subject svn commit: r1447943 - in /qpid/proton/trunk: proton-c/src/codec/codec.c tests/interop/described_array.amqp tests/python/proton_tests/interop.py
Date Tue, 19 Feb 2013 22:22:05 GMT

New Revision: 1447943

URL: http://svn.apache.org/r1447943
Log:
PROTON-232: described arrays seem to force the descriptor to be of the same type as the array

Fixed bug in code.c pn_data_encode_node: was always using the parent->type
for everything inside an array, including the descriptor.
