k-wall commented on pull request #30: PROTON-1998: Add SASL protocol trace
URL: https://github.com/apache/qpid-proton-j/pull/30
This patch adds a SASL protocol trace that is controlled by the same
mechanism as the main protocol trace.
Could you comment on the approach? If it is acceptable, I'll add some tests.
One unsettled question in my mind ProtocolTracer: at the moment,
ProtocolTracer implementations don't receive SaslFrameBodies. I did as this
would break ProtocolTracer impls (including QpidJMS's - which would
ClassCastException). I wondered using a default method
ProtocolTracer#ignoreSaslFrameBody which would return true. Comments
appreciated..

> [Proton-J] Add SASL protocol trace
> ----------------------------------
>
> Key: PROTON-1998
> URL: https://issues.apache.org/jira/browse/PROTON-1998
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-j
> Reporter: Keith Wall
> Priority: Minor
>
> Unlike Proton, Proton-J does not provide SASL frame trace if environment
> variable PN_TRACE_FRM is set. It would be useful if Proton-J had this
> ability too to help diagnose SASL negotiation problem.
> Proton's SASL frame trace looks like this:
> {code:java}
> [0x7fc112c03a00]: -> SASL
> [0x7fc112c03a00]: <- SASL
> [0x7fc112c03a00]:0 <- @sasl-mechanisms(64)
> [sasl-server-mechanisms=@PN_SYMBOL[:ANONYMOUS]]
> [0x7fc112c03a00]:0 -> @sasl-init(65) [mechanism=:ANONYMOUS,
> initial-response=b"guest@Oslo.local"]
> [0x7fc112c03a00]:0 <- @sasl-outcome(68) [code=0]
> [0x7fc112c03a00]: -> AMQP
> [0x7fc112c03a00]:0 -> @open(16)
> [container-id="be777c26-af6e-4935-a6be-316cc8bbdb35", hostname="127.0.0.1",
