0.22.0

  • Add the :record_on_server_receive configuration option.

0.21.2

  • Bugfix: Guard against tracer not set in Faraday and Excon middlewares

0.21.1

0.20.1

  • Bugfix: Properly handle the sampled_as_boolean configuration option

0.20.0

  • Bugfix: The Faraday middleware does not leave in the container any generated Id
  • Added TraceContainer and TraceGenerator to provide easier abstractions to interact with this library

0.19.1

  • Limits the required headers to x_b3_trace_id and x_b3_span_id as per spec.

0.19.0

  • Propagates the X-B3-Sampled in the same form it receives it (boolean or 1/0)
  • Adds a configuration option to allow a service to emit boolean or numbers for the X-B3-Sampled header

0.18.6

  • Passes HTTP Method to recognize_path

0.18.5

  • NullTracer has a noop flush! method.
  • Spans from local_component_span will be named according to local_component_value over lc.

0.18.4

  • Uses http.path to annotate paths instead of http.uri.

0.18.3

  • Ensures ip addresses for all hostnames are resolved, solves issue with docker hostnames

0.18.2

  • Remove nil parentId from zipkin span payload.

0.18.1

  • Turn the ZipkinTracer::FaradayHandler::B3_HEADERS constant into a private method

0.18.0

  • Adds the :log_tracing option to explicitly use the logger tracer.
  • Logger classes can not be passed via the configuration file (never worked correctly).
  • Logger tracer logs in JSON format for easy analysis by other tools.

0.17.0

Adds a :producer configuration key as an alternative to Hermann as Kafka client.

0.16.0

  • Remove the scribe tracer.
  • Use sucker_punch 2.x. The main feature is the dependency on concurrent-ruby instead of celluloid.

0.15.1

  • Less strict dependency on Rack. Allows to use Rails 5.

0.15.0

  • Hostname resolution done asyncronously for the JSON tracer

0.14.1

  • Access to the tracer when we need it and not before.

0.14.0

  • Adds a logger kind of tracer.

0.13.2

  • Move record methods in TraceClient to Span
  • Relocate definition of constant variables

0.13.1

  • Check the config entry is not blank when infering adapters

0.13.0

  • Remove support for buffering. It was broken anyways.

0.12.2

  • Make local tracing method (ZipkinTracer::TraceClient.local_component_span) returns the result of block

0.12.1

  • Allow nesting of local tracing spans

0.12.0

  • Add local tracing, fix flushing, add timestamp and duration to span

0.11.0

  • Use local spans instead of thread-safe variables to improve performance
  • Add new with_new_span method to the tracer api to allow creating custom spans

0.10.3

  • Avoid requiring finagle-thrift when possible to avoid a hard dependency on Thrift

0.10.2

  • Add faraday as a dependency

0.10.1

  • Performance optimization: Do not create tracing related objects in the Faraday middleware if we are not sampling.
  • Fix benchmark Rake task so it uses the proper Faraday middlewares

0.10.0

  • Always create trace IDs even when the trace will not be sent to zipkin (other parts of the app may use them).
  • Bugfix: Tracer is now Threadsafe
  • Development improvement: Benchmark Rake task to help finding performance issues

0.9.1

  • Make Scribe actually optional by inspecting the conf first and requiring after.

0.9.0

  • Add a JSON tracer (ZipkinJsonTracer).

0.8.1

  • Set caller service name using domain environment variable. If the value is not set, it will fall back to the configuration file default.

0.8.0

  • To proper follow the correct spec, now the annotations cr/cs set the local service as servicename
  • Added a 'sa' annotation to indicate the remote service servicename

0.7.3

  • Rescue possible errors when lookup of the hostname fails

0.7.1

  • Remove Scribe from direct dependencies list

0.7

  • The ruby client does not wait to receive ACK from the collector. Just send traces
