|
||
|

|
||
|
|
## [v0.17.0](https://github.com/lightstep/lightstep-tracer-go/compare/v0.16.0...v0.17.0)

|
|
|
||
|
|
## [v0.16.0](https://github.com/lightstep/lightstep-tracer-go/compare/v0.15.6...v0.16.0)
|
||
|
|
* Thrift transport is eliminated
|
||
|
|
* If no transport is specified, UseHTTP is now the default (was UseGRPC)
|
||
|
|
* Requires go >= 1.7
|
||
|
|
* Update to gogo-1.2.1, no longer using Google protobuf
|
||
|
|
* Imports `context` via the standard library instead of `golang.org/x/net/context`
|
||
|
|
* Fixes [#182](https://github.com/lightstep/lightstep-tracer-go/issues/182), so that `StartSpan` can now take `SpanReference`s to non-LightStep `SpanContext`s use
|
||
|
|
* Adds experimental OpenCensus exporter
|
||
|
|
* Access-Tokens are passed as headers to support improved load balancing
|
||
|
|
* Support for custom TLS certificates.

|
|
|
||
|
|
## [v0.15.6](https://github.com/lightstep/lightstep-tracer-go/compare/v0.15.5...v0.15.6)
|
||
|
|
|
||
|
|
* Minor update to `sendspan` to make it easier to pick which transport protocol to use.
|
||
|
|
* Add a new field to Options: DialOptions. These allow setting custom grpc dial options when using grpc.
|
||
|
|
* This is necessary to have customer balancers or interceptors.
|
||
|
|
* DialOptions shouldn't be set unless it is needed, it will default correctly.
|
||
|
|
* Added a new field to Endpoint: Scheme. Scheme can be used to override the default schemes (http/https) or set a custom scheme (for grpc).
|
||
|
|
* This is necessary for using custom grpc resolvers.
|
||
|
|
* If callers are using struct construction without field names (i.e. Endpoint{"host", port, ...}), they will need to add a new field (scheme = "").
|
||
|
|
* Scheme shouldn't be set unless it needs to overridden, it will default correctly.
|
||
|
|
|
||
|
|
## [v0.15.5](https://github.com/lightstep/lightstep-tracer-go/compare/v0.15.4...v0.15.5)
|
||
|
|
* Internal performance optimizations and a bug fix for issue [#161](https://github.com/lightstep/lightstep-tracer-go/issues/161)
|
||
|
|
|
||
|
|
## [v0.15.4](https://github.com/lightstep/lightstep-tracer-go/compare/v0.15.3...v0.15.4)
|
||
|
|
* This change affects LightStep's internal testing, not a functional change.
|
||
|
|
|
||
|
|
## [v0.15.3](https://github.com/lightstep/lightstep-tracer-go/compare/v0.15.2...v0.15.3)
|
||
|
|
* Adds compatibility for io.Writer and io.Reader in Inject/Extract, as required by Open Tracing.
|
||
|
|
|
||
|
|
## [v0.15.2](https://github.com/lightstep/lightstep-tracer-go/compare/v0.15.1...v0.15.2)
|
||
|
|
* Adds lightstep.GetLightStepReporterID.
|
||
|
|
|
||
|
|
## [v0.15.1](https://github.com/lightstep/lightstep-tracer-go/compare/v0.15.0...v0.15.1)
|
||
|
|
* Adds Gopkg.toml
|
||
|
|
|
||
|
|
## [v0.15.0](https://github.com/lightstep/lightstep-tracer-go/compare/v0.14.0...v0.15.0)
|
||
|
|
* We are replacing the internal diagnostic logging with a more flexible “Event” framework. This enables you to track and understand tracer problems with metrics and logging tools of your choice.
|
||
|
|
* We are also changed the types of the Close() and Flush() methods to take a context parameter to support cancellation. These changes are *not* backwards compatible and *you will need to update your instrumentation*. We are providing a NewTracerv0_14() method that is a drop-in replacement for the previous version.
|
||
|
|
|
||
|
|
## [v0.14.0](https://github.com/lightstep/lightstep-tracer-go/compare/v0.13.0...v0.14.0)
|
||
|
|
* Flush buffer syncronously on Close.
|
||
|
|
* Flush twice if a flush is already in flight.
|
||
|
|
* Remove gogo in favor of golang/protobuf.
|
||
|
|
* Requires grpc-go >= 1.4.0.
|
||
|
|
|
||
|
|
## [v0.13.0](https://github.com/lightstep/lightstep-tracer-go/compare/v0.12.0...v0.13.0)
|
||
|
|
* BasicTracer has been removed.
|
||
|
|
* Tracer now takes a SpanRecorder as an option.
|
||
|
|
* Tracer interface now includes Close and Flush.
|
||
|
|
* Tests redone with ginkgo/gomega.

|
||
|
|
* Added CloseTracer function to flush and close a lightstep recorder.
|
