-------------------------------------

             Summary: By default the flag that allows AMQP SASL and OPEN frames to be pipelined must be turned off 
                 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


Dispatch router (which uses Proton-c) sends pipelined SASL and OPEN frames by default like shown in the following trace - 
{code}
[0x7f41f80079c0]:  -> SASL
[0x7f41f80079c0]:0 -> @sasl-init(65) [mechanism=:ANONYMOUS, initial-response=b"anonymous@localhost.localdomain"]
[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, idle-time-out=8000, offered-capabilities=@PN_SYMBOL[:"ANONYMOUS-RELAY"], properties={:product="qpid-cpp", :version="0.35", :platform="Linux", :host="localhost.localdomain"}]
{code}
As per the AMQP 1.0 spec - the OPEN frame is sent after the SASL exchange is complete as shown below - 
{code}
TCP Client         TCP Server
=========================================
AMQP%d3.1.0.0 --------->
                          <--------- AMQP%d3.1.0.0
:
:
<SASL negotiation>
:
:
AMQP%d0.1.0.0 --------->
(over SASL secured connection)
                            <--------- AMQP%d0.1.0.0
open --------->
                            <--------- open
{code}
Proton should by default turn off the flag that enables sending pipelined OPEN frames.
