Susan Hinrichs resolved TS-3191.
--------------------------------
Resolution: Fixed
> Confusion with HTTP_TUNNEL_STATIC_PRODUCER
> ------------------------------------------
>
> Key: TS-3191
> URL: https://issues.apache.org/jira/browse/TS-3191
> Project: Traffic Server
> Issue Type: Bug
> Reporter: Susan Hinrichs
> Assignee: Susan Hinrichs
> Fix For: 5.2.0
>
>
> In the HttpTunnel processing, normally a producer has a VC associated with
> it. The VC is used to lookup the producer via the HttpTunnel::get_producer
> method out of the HttpTunnel producer array.
> All is well and good, but in the case of a static producer, there is no vc.
> Rather the constant HTTP_TUNNEL_STATIC_PRODUCER is used in lieu of the vc.
> If there is only only one static producer all is still well, get_producer
> will return the one producer associated with HTTP_TUNNEL_STATIC_PRODUCER.
> But if there is more than one static producer involved with the tunnel,
> get_producer() will only return one producer. Both static consumers will
> only interact with one of the static producers and things will go down hill
> from here.
> I ran into this case while chasing down crashes via TS-3105, so this
> situation does come up in the wild.
> I fixed it by clearing out the tunnel before starting a static producer and
> making some other checks along the way.
> We could also avoid some calls to get_producer since it many cases, the
> caller already has the producer in question, but the callee ends up looking
> up that value again via the VC.
