brave-3.0.0-alpha-1
8cab167

First public release of brave 3.0.0. It is an Alpha release as it is not feature complete yet.
Components are available in Maven Central.

This is a breaking change when coming from brave 2.x. However the changes you need to do to upgrade should be minimal and expected to be straight forward.

List of changes:

  • [Breaking change] Java 7 bytecode (was Java 6 for brave 2.x). Build and release was done using Java 8.
  • Module changes:
    • flume-zipkin-collector-sink is extracted from brave project and lives in separate repo now
    • flume-zipkin-metrics-sink is extracted from brave project and lives in separate repo now
    • brave-interfaces and brave-impl have been merged into new module: brave-core
    • brave-client module is renamed into brave-http as it was very http focused anyway
  • Upgrade modules that depend on Spring to use Spring 4.1.6.RELEASE. However the Spring dependencies have scope provided and you are not forced to update from Spring 3 if you don't want to. All Spring dependent modules should also still work with Spring 3.2.2.RELEASE or later.
  • Groundwork for new client and server abstractions that are not http specific. These classes and interfaces (ServerRequestInterceptor, ServerResponseInterceptor, ClientRequestInterceptor, ClientResponseInterceptor) live in brave-core but are not integrated yet. This will be for next alpha or beta release.
  • Contributions by @adriancole . Big thanks!
    • Introduce animal-sniffer Maven plugin to make sure we don't accidently introduce Java 8 features in brave-core.
    • Remove guava as a dependency.
    • [Breaking change] Consolidate Impl classes and interfaces in brave-core : Interfaces which really only have and need 1 implementation have been merged into single class (interface becomes class)
    • [Breaking change] Introduce Google AutoValue which removes lots of boilerplate code and also enabled the removal of commons-lang3 dependency \o/.
    • [Breaking change] Rename EndPointSubmitter to EndpointSubmitter.

brave-resteasy-example has been updated to use brave 3.0.0-alpha1.
