now instead of first passing all the spans from the queue to the list and then clearing it we're now draining it contents. If in the meantime any spans will arrive they will be rained at next passing
fixes#259
The FeignBeanPostProcessor was causing other things to misbehave
by forcing early instantiation of all its dependencies. One of those
is a @MessageEndpoint when Sleuth Stream is in use, and the annotation
wasn't being processed because the bean was processed too early.
* Fixed the HttpServlet extractors
(now the response can contain custom headers)
* Changed header names to be Zipkin compatible
* removed qualifiers and properties
* updated the docs
fixes#19
* TraceKeys -> moved to root
* TraceRunnable and TraceCallable moved to root
* Websockets moved as a subpackage of messaging
* created TraceMetricsAutoConfiguration in the metric package (thanks to this the TraeAutoConfiguration doesn't need any metric info)
What’s left?
* the remaining dependencies are related to everybody using events
* there are a couple of usages of NeverSample
Also allows us to actually create a PercentageBasedSampler (I
don't think anyone tried it before) without resorting to
lazy beans and proxies.
Another freature added here is a default percentage sampler
if we know that spans need to be exported (zipkin or stream
is present).
Fixes gh-138
It also turns out that there's a bug in Spring MVC which makes an
empty header blow up in RequestHeaderMapMethodArgumentResolver
so we set the header to "true" instead of empty.
Fixes gh-136
Changes following review
- Reusing CounterService to automatically profit from Dropwizard if present
- NoOp is the default impl for SpanReporterService
- SpanReporterService has configurable metric names (it's enough to change the
name to 'meter.a.b.c' to profit from Dropwizard's meters)
Fixes gh-99
- Changed Random instantiation to a shared Random
- Changed the name of the converter
- Changed generator into random
- Span id is now non-nullable.
- it gets generated in the http filter if it's not there
- it's generated in the spring-integration channels if it wasn't set
