* Adjusts expectations of data reporting of loopback spans
The latest version of Brave corrects a data merge problem where shared
spans (created via Tracer.joinSpan) would lose some data. Along the way,
this fixes some misuse of `Tracer.joinSpan` which should only be used
for RPC server spans.
See https://github.com/openzipkin/brave/pull/734 applied in Brave 5.1.3
* Makes the test more better
without this change we wrapped in the handleSend and handleReceive both the method wrapping the execution of the TraceLoadBalancerFeignClient and its delegate too. That way we had 2 pairs of CS & CR.
with this change we disable that functionality by wrapping only the delegate. The problem with such an approach was such that there were exceptions thrown before the delegate was executed. That's why we added a fallback mechanism in that case.
fixes gh-1007
without this change the kafka binder wasn't able to propagate tracing headers without explicitly adding on classpath the deprecated sleuth-stream module
with this change we're adding the stream support in core of Sleuth
fixes gh-1005
without this change the instrumentation of RibbonCommand lead to creation of an additional client span
with removal of the instrumentation of the RibbonCommand no longer do we create that span
fixes gh-997
This is done by implementing NO-OP QueueSubscription on the subscriber
and removing the guard against `Fuseable` publisher sources.
As `Fuseable` is a marker interface there should be no reason for code
to perform casts so for now the fact that the `lift` call in
ReactorSleuth doesn't actually produces a `Fuseable` publisher should
not be a problem.
fixes gh-994
we've played around with the working M7 version, and only after rolling back the changes on wrapping of onError and onComplete with try-with-resources, did we manage to successfully propagate the span context to various places.
fixes gh-973
with this change we're returning immutable headers of non stomp messages. That way timestamp and id of the message will be set. For stomp messages the headers still have to be mutable
