---------------------------------
Summary: [C++ Broker, AMQP1.0] Broker fails to detect stolen link
attempt
Key: QPID-6277
URL: https://issues.apache.org/jira/browse/QPID-6277
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: 0.30
Environment: Linux broker
Reporter: Chuck Rolke
A client program opens two identically named links to the same container. AMQP
spec section 2.6.1 describes the link *stolen* link error state but that might
not apply here. The broker is free not to honor the second attach request but
if it does then the incoming attach should get an error. As it is the failed
attach request is simply ignored.
The attached trace shows Frame 44 delivering the first attach which is
accepted. Frame 59 shows the attach which is ignored.
The proton subsystem delivers the @attach(18) frame to the broker. In
Connection :: Process() line 354 Frame 44 is intercepted because a link
REQUIRES_OPEN. Frame 59 skips the link_open processing and goes directly to
processDeliveries().
