Hallo,
I observe strange thing when using temporary queues in client.py script.
I assign delete-on-close policy to temporary queue as follows:
options=DynamicNodeProperties({"lifetime-policy" : ['amqp:delete-on-close:list', []],
"exclusive" : True })
But when I check the trace I see that delete-on-close is replaced by
delete-on-no-link:
[0x1759b60]:0 <- @attach(18)
[name="67234240-c66b-4936-9498-e0e66013b355-6d4569a2-f9f7-43c1-b87a-6f99976e81d9",
handle=1,
role=false, snd-settle-mode=2, rcv-settle-mode=0, source=@source(40)
[address="67234240-c66b-4936-9498-e0e66013b355_67234240-c66b-4936-9498-e0e66013b355-6d4569a2-f9f7-43c1-b87a-6f99976e81d9",
durable=0, timeout=0, dynamic=false,
dynamic-node-properties={:"supported-dist-modes"="move",
:"lifetime-policy"=@:"amqp:delete-on-no-links:list" [], :exclusive=true},
distribution-mode=:move], target=@target(41)
[durable=0, timeout=0, dynamic=false], initial-delivery-count=0,
max-message-size=0]
When I assign same property in c++ code it is shown in trace correctly:
[0xb37260]:0 <- @attach(18) [name="receiver-10599.0", handle=0, role=false,
snd-settle-mode=2, rcv-settle-mode=0,
source=@source(40)
[address="EB39BD71-C919-4936-A7C9-65334513620D_receiver-10599.0", durable=0,
timeout=0, dynamic=false,
dynamic-node-properties={:"supported-dist-modes"="move",
:"lifetime-policy"=@:"amqp:delete-on-close:list" [], :exclusive=true},
distribution-mode=:move], target=@target(41) [durable=0, timeout=0,
dynamic=false], initial-delivery-count=0, max-message-size=0]
I grepped through proton 0.28 code for 'delete-' tokens but did not find
anything
that looked like delete-on-close replacement.
Can you help me to find where the replacement occurs in python?
It is not being replaced, but your attempt to set it is failing as it
needs to be a described type, and the default is used instead.
Replace
['amqp:delete-on-close:list', []]
with
Described('amqp:delete-on-close:list', [])
(The Described type is imported from the base proton module)
