Ganesh Murthy created PROTON-1135: ------------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
