Appears to emit no valid protocol header? about azure-uamqp-python HOT 3 OPEN

Thanks @grs for these details!!
I will try to repro :)

The only thing I can answer off the top of my head is the 100% CPU use - I generally assume that establishing the connection and authentication will a be quick process and therefore I made no effort to slow down iterating the connection as much as possible during this process.

Clearly this assumption is invalid in circumstances where:

• The connection or authentication takes time to establish
• For whatever reason the connection fails to establish

So I will revisit the design there.

Again, thanks!

I've tripped across this issue as well when trying to use uAMQP against an ActiveMQ Artemis server.

If it helps I get an error in the artemis.log file on the broker:

AMQ224096: Error setting up connection from /localhost:53814 to /localhost:5672; protocol CORE not found in map: [AMQP]

For my test I tried using both plain and anonymous authentication. Both cause the same error on the broker and the client just hangs.

Thanks for the report @egandone - I would really like to invest the time in getting this project working with these other AMQP servers - though unfortunately I wont be able to in the immediate future :(

I will hopefully be able to revisit this in the coming months as we are on-boarding more people to help with these projects.
