-----------------------------------
Summary: [C++ broker] [AMQP 1.0] wrong encoding/decoding of
boolean type
Key: QPID-5424
URL: https://issues.apache.org/jira/browse/QPID-5424
Project: Qpid
Issue Type: Bug
Components: C++ Broker, C++ Client
Affects Versions: 0.24, 0.22
Reporter: Pavel Moravec
Both encoding/decoding AMQP 1.0 boolean primitive type seems to be wrong - it
lacks specifying type constructor (0x56).
E.g. taking tcpdump of a client communication, I got PDU:
0000008e02000000005312d00000007e0000000aa12d6d795175657565325f66373562326532622d613930392d343063612d393832652d65323630386666623439363652004150025000005328d00000001a0000000ba1086d79517565756532520040520042404040404040005329d00000001600000007a1086d79517565756532520040520042404040405200
that is disassembled to:
0000008e = size(142)
02000000 = rest of header
00(descriptor_constructor) 53(fixed_one) 12(attach performative)
d0 = compound-four, i.e. list32
0000007e(size=126)
0000000a(count=10)
(Name): a1(str8) 2d(len=45)
6d795175657565325f66373562326532622d613930392d343063612d393832652d653236303866666234393636(myQueue2_f75b2e2b-a909-40ca-982e-e2608ffb4966)
(Handle): 52(smalluint) 00(0)
(Role): 41.. = boolean value???
I see this reoccuring in any tcpdump I take - sometimes with Role 0x41
("true"), sometimes 0x42 ("false"), depending on receiver/sender role of the
peer.
As the bug is present both in encode and decode, neither broker or client
complains of malformed PDU.
I see it in 0.22 while assume it in upstream as well (no change in relevant
source code since that).
