             Summary: qdstat sometimes raises "TypeError: 'NoneType' object is not iterable"
                 Key: DISPATCH-1254
                 URL: https://issues.apache.org/jira/browse/DISPATCH-1254
             Project: Qpid Dispatch
          Issue Type: Bug
          Components: Routing Engine
    Affects Versions: 1.2.0
            Reporter: Alan Conway
            Assignee: Ganesh Murthy
         Attachments: qdr-chain.sh

Set up a chain of 4 routers, each connected to the previous. Wait for qdstat -nv at router 1 to show 4 routers in the known topology. Receive messages from address x at router 4, send to address x from router 1. Messages are rejected at the sender.

Reproducer: 

make install this version of quiver (extented to allow separate send/receive URLS). If you have maven installed you should edit the makefile to disable the Java arrow as the build is very slow and fragile:

    [https://github.com/alanconway/quiver]

run the attached script like this:

    qdr-chain.sh quiver --timeout 60 --arrow c  --count 1000 --send-url //:10001/x //:10004/x     

The script generates config files, starts four routers, waits for qdstat -nv to show the full topology and then runs quiver as directed. Edit the script to change logging or other config settings. Log and config files are created in the current directory.

WARNING the script will kill any running qdrouterd.

I see the sender fail with this error:

    impls/quiver-arrow-qpid-proton-c.c:307: bad delivery: pn_delivery<0x8aad20>\{sending, tag=b"\x01\x00\x00\x00\x00\x00\x00\x00", local=unknown, remote=rejected} 

NOTE: the script configures the address "testme" on all 4 routers, if you run the test like this it passes:

    qdr-chain.sh quiver --timeout 60 --arrow c  --count 1000 --send-url //:10001/testme //:10004/testme
