Stomp frame header 'persistent:1' in non-persistent message

[in...@habarisoft.com]

Hi,

I think it there is a noteworthy unexpected value of the 'persistent' header of the MESSAGE frame sent from RabbitMQ to Stomp clients. This occurs when I publish a 'non-persistent' message to a 'classic' queue from the web interface. 

The queue has been created using the web interface, with durabilitiy set to "transient".

My Stomp client subscribes to the destination as follows:

SUBSCRIBE

destination:/queue/nondurable

ack:auto

id:{7F8FBD85-8A6D-41EF-936D-38D9D1A1C4B9}

durable:false

exclusive:false

auto-delete:false

Now I publish a 'non-persistent' message to the queue from the web interface. 

A MESSAGE frame is received in a Stomp client with 'persistent' header value '1', I would expect a 'false' here.

MESSAGE

subscription:{7F8FBD85-8A6D-41EF-936D-38D9D1A1C4B9}

destination:/queue/nondurable

message-id:T_{7F8FBD85-8A6D-41EF-936D-38D9D1A1C4B9}@@session-I6kB3IwcYD-ac7LL6nEPHg@@1

redelivered:false

persistent:1

content-length:4

Test

Should I create a issue in the Github bug tracker?

Hi,

I can reproduce your results but I can also see a difference based on the persistence of the message I publish.

When I publish a persistent message, I see "persistent: true" but when I publish a non-persistent message,

I get "persistent: 1". My guess is that this is a leaky translation of AMQP to STOMP - in AMQP delivery-mode

of 1 means non-persistent and delivery-mode=2 means persistent. Seems like the latter is translated to "true"

but the former is left as-is. Looking at the STOMP spec (https://stomp.github.io/stomp-specification-1.2.html)

I don't see any specification of what this value should be - just that the headers can be used to provide such information.

Assuming all of the above is correct, is it ok for you? Can you just treat 1 as false?

Disclaimer: I know close to nothing about STOMP so please bear with me. :)
