with this fix if someone is not using Feign he gets the default traced Feign.Builder. Thanks to this no more exceptions should be seen in terms of closing the wrong span.
fixes#350
Makes use of property place holders to set the patterns attribute of the
@GlobalChannelInterceptor annotation used for the
TraceChannelInterceptor. As supported by the annotation, only simple
patterns are supported.
Added the Spring configuration metadata for spring.sleuth.integration
properties.
Fixes gh-323
with this change the missing methods in ExecutorService are wrapped with LocalComponentTraceCallable. We are wrapping only those callables that have not already been wrapped. Kudos to @PranayPS for finding the issue and proposing a solution.
Fixes#333
* Fix headers in messaging
with this change the span related headers are changed to be compatible with messaging specs. The change is backwards compatible so we accept the old ones as input, and as output we're producing both new and old headers.
fixes#332
* Re-added missing server side span
with this change
- HandlerInterceptor is responsible for wrapping requests in spans
- added Sring Data REST instrumentation
- added Zuul instrumentation
- it will not wrap error controller related requests with spans
- tests have been changed to ensure that ALWAYS there is at least one span on the server side (that way it will show up in Zipkin)
- "fallback" mechanism has been added that if a HandlerInterceptor hasn't been used then we are forcing creation of a Span at the server side
fixes#321
Formerly, `Span.getAccumulatedMillis()` worked, but could returns
imprecise measurements, particularly local spans. This changes the
internals of Span to keep track of a start tick. Using this, it can
return a more precise `Span.getAccumulatedMicros()`.
To ensure this precision isn't lost in serialization, this adds a
json field `durationMicros`, which is only set when the span is stopped.
This is set instead of start tick because `System.nanoTime()` is JVM
specific and so cannot be used across the network. `durationMicros` uses
null instead of zero comparisons because nano time can be negative.
Fixes#312
with this change the child span of the HTTP filter span gets changed into a span coming from the Controller aspect. The name of the span becomes the name of the method.
with this change we will throw an IllegalArgumentException when the malformed tracing data are sent. In TraceFilter we're catching it and sending back 400 response. In case of messaging the exception gets propagated
fixed#306
* Changes following review
* Changes following review
with this change we're trying to retrieve the value of span / trace id from a header but we don't propagate the exception if that value is invalid. Instead we generate a new random value. It's better not to break the application and break the trace (if by any chance it's been corrupt).
Fixed#306
TraceFilter no longer is a OncePerRequestFilter
TraceFilter processes the request that is executed upon ERROR dispatch (the logs will be present there)
Altered the logic in TraceFilter that an already processed request will not be detached (which resulted in an exception)
Added some debugging to instrumentation
Added assertion over a list of spans
Bumped up SC-Netflix to 1.1.2.BUILD-SNAPSHOT
Added Zuul integration tests
Added Http keys injection to Zuul client call
