Clifford Jansen created PROTON-2517:
---------------------------------------
Summary: The new C codec can misinterpret pn_data_t values
resulting in unintended wire data.
Key: PROTON-2517
URL: https://issues.apache.org/jira/browse/PROTON-2517
Project: Qpid Proton
Issue Type: Bug
Components: proton-c
Affects Versions: proton-c-0.37.0
Reporter: Clifford Jansen
Assignee: Clifford Jansen
See the C++ frame trace from
https://issues.redhat.com/browse/ENTMQCL-3278
The zero length array is printed instead of a null because the test in
emit_multiple() from emitters.h fails to set the current node of the pn_data_t
to the first node. The test
if (pn_data_type(data) == PN_ARRAY) { //...
fails and the array processing logic is bypassed, including the lines
switch (pn_data_get_array(data)) {
case 0:
pni_emitter_writef8(emitter, PNE_NULL);
