opentracing

• Fix circular dependency in mock_context (#154) -- thanks Jonathan Moody

0.14.4

• Add trace identifiers to the SpanContext

• Removed the dependency on lodash in the API compatibility checks as it was causing errors when the tests were run if lodash was not explicitly installed.

• SpanOptions is now exported from the library.

• MockTracer is now exported from the library.

• The checkBaggageValues option has been replaced with skipBaggageChecks and the skipInjectExtractChecks option has been added in the API compatibility checks.

• The globalTracer delegate will now correctly call startSpan, inject and extract with the configured global tracer as this.

• TypeScript rewrite: Now brings TypeScript typings out of the box

• Removed lib-debug and runtime type checks

• Removed spanOptions.operationName

• The main entry point can no longer be imported with a default import

If you previously used a default import like this:

import opentracing from 'opentracing'

change it to

import * as opentracing from 'opentracing'

Contains API breaking changes for both library users and tracing implementations

• Introduces key-value logging API

Contains API breaking changes for both library users and tracing implementations

• The package no longer exports the singleton, global tracer by default. globalTracer() should be used to access the global tracer

• Implementation no longer use a TracerImp object. Implementations should instead subclass from opentracing.Tracer, opentracing.Span, etc.

• The removal of the TracerImp object implies there is no longer an imp() method. Implementation-specific methods now exist in undifferentiated form on the tracer object. Note: the OpenTracing library no longer forces the user to be explicit when calling implementation-specific methods; this has the downside that it is less obvious when an application becomes dependent on a specific tracing implementation.

• initNewTracer() has been removed. The Tracer implementation object should be created directly by the library user.

• The default no-op Tracer.extract() implementation now returns an empty SpanContext rather than null

• childOf and followFrom have been moved from Tracer to standalone functions

• Tracer.flush has been removed. It is not part of the OpenTracing spec.

• Support for the Tracer.startSpan(fields) signature has been removed. It must always be called as Tracer.startSpan(name, [fields])

Non-breaking changes

• A MockTracer implementation has been added to the source code

• Adds a naive example, runnable via make example

• Use the referee terminology within Reference

• Fix a bug with the treatment of startSpan's fields.childOf

• Move to SpanContext, Reference, and s/join/extract/g
