---------------------------------------
Assignee: Andrew Stitcher
> [proton-c] dont pipeline SASL and OPEN frames for ANONYMOUS logins by default
> -----------------------------------------------------------------------------
>
> Key: PROTON-1135
> URL: https://issues.apache.org/jira/browse/PROTON-1135
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.12.0
> Reporter: Ganesh Murthy
> Assignee: Andrew Stitcher
>
> Dispatch router (which uses Proton-c) currently sends pipelined SASL and OPEN
> frames by default when connecting out to other peers using the ANONYMOUS
> mech, as shown in the following trace -
> {code}
> [0x7f41f80079c0]: -> SASL
> [0x7f41f80079c0]:0 -> @sasl-init(65) [mechanism=:ANONYMOUS,

> [0x7f41f80079c0]: -> AMQP
> [0x7f41f80079c0]:0 -> @open(16) [container-id="Qpid.Dispatch.Router.A",
> max-frame-size=65536, channel-max=32767, idle-time-out=8000,
> offered-capabilities=:"ANONYMOUS-RELAY",
> properties={:product="qpid-dispatch-router", :version="0.6.0"}]
> [0x7f41f80079c0]: <- SASL
> [0x7f41f80079c0]:0 <- @sasl-mechanisms(64) [sasl-server-mechanisms=:ANONYMOUS]
> [0x7f41f80079c0]:0 <- @sasl-outcome(68) [code=0]
> [0x7f41f80079c0]: <- AMQP
> [0x7f41f80079c0]:0 <- @open(16)
> [container-id="ce103199-af03-4d37-bb35-24ad4e55653e", channel-max=32767,

> properties={:product="qpid-cpp", :version="0.35", :platform="Linux",
> :host="localhost.localdomain"}]
> {code}
> The AMQP 1.0 spec does not make it clear that this is supported (e.g. see
> diagram below) but in any case various components have shown difficulty with
> it (such as PROTON-1135 just raised, and QPID-6639 which has yet to be
> included in a release but permitted the above protocol trace log).

> Proton should by default disable sending pipelined OPEN frames for ANONYMOUS
> logins, to aid compatibility with other components that don't expect/handle
> such behaviour.
