Now that Endpoint has ipv6, the factory method is even worse than it
was before. This switches to a builder instead.
Note: Endpoint now has a nice toString which should help debugging.
AsyncReporter is a more robust version of what we were doing before.
Notably, it can give a memory threshold instead of span count for the
backlog. This change ports to use AsyncReporter internally.

Sleuth doesn't create I64 binary annotations, but others might. This
version of zipkin fixes an encoding bug when someone logs a binary
annotation of type I64.
This updates to Zipkin 1.6, which targets Spring Boot 1.4
Zipkin 1.6 also corrects default values around the UI, which should lead
to better search performance.
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
Zipkin 1.1.1 includes a few changes relevant to sleuth:
* Adds JSON button to trace detail screen
* Presents server errors in UI
* Fixes misclassification of http span metrics (1.1.1)
https://github.com/openzipkin/zipkin-java/releases/tag/1.1.0
This moves to changes made in preparation of zipkin 1.0.
Here are the notables:
* Zipkin has autoconfiguration modules, where maven artifacts have the prefix 'zipkin-autoconfigure-X'
* Zipkin's ui now shares a version with everything else
* Zipkin now namespaces packages and configuration. ex zipkin.storage.X as opposed to zipkin.X
* All autoconfiguration classes are prefixed `Zipkin` to be easier to find
* Zipkin binds components like StorageComponent, as opposed to individual classes like SpanStore.
* Health checks are under the scope "zipkin" and broken down by component
* UI responsiveness is better by conditionally caching names queries for 5 minutes
* New `Collector` class, which makes logging and metrics patterns the same regardless of transport
This important in so far that it allows us to do metrics. The actual
implementation of stream metrics is something we can work on after 1.0
if there's a time crunch.
Notably, this removes the accidental transient dependency on scala, by
removing the dependency on `zipkin-cassandra-core`. Related classes have
been vendored into `storage-cassandra`.
This also splits out `CollectorSampler` as its own thing and introduces
two options for instrumentation sampling:
* `BoundaryTraceIdSampler` - For high-volume sites, based on Finagle
* `CountingTraceIdSampler` - Trades lower performance for high accuracy
No immediate impact to sleuth, but some notable changes underneath:
* zipkin.Sampler is now extensible to permit dynamic rate adjustments
* self-tracing can now be disabled even if Brave is in the classpath
* related property: zipkin.self-tracing.enabled
* brave-spancollector-scribe is no longer an optional dependency
In the world of plugins:
* Elasticsearch bugfix on traces w/ more than 10 spans
* New ZooKeeper adaptive collection-tier sampler
This updates to the latest release. Beyond bug fixes, there are some
notable changes:
* storage: writes are now via AsyncSpanConsumer
* storage: added elasticsearch
* zipkin-ui: constrains start time to look for traces
* zipkin-ui: assets set cache headers, increasing responsiveness
* core: debug logging available for zipkin.internal.DependencyLinker
Notably, this removes the "zipkin-web" dependency, as the UI is now
collocated on zipkin-server.
Other notable changes are Cassandra and Kafka support, as well removing
the Brave dependency.
This is a maintenance update to zipkin which has no api impact.
* zipkin-server supports cassandra now
* zipkin-web is now javascript (even if still hosted on a scala process)
This updates to latest zipkin, adding a flag to gzip spans before
posting them. Note this is set to false by default as it requires servers
to also be latest. We can flip the default once we can assume that.
Ex. `spring.zipkin.compression.enabled = true`
