+2.20.0 (2019-11-06)
+-------------------
+
+## New Features
+
+- Allow all in-process spans of a trace to share sampling state (#443) -- Prithvi Raj
+
+ Sampling state is shared between all spans of the trace that are still in memory.
+ This allows implementation of delayed sampling decisions (see below).
+
+- Support delayed sampling decisions (#449) -- Yuri Shkuro
+
+ This is a large structural change to how the samplers work.
+ It allows some samplers to be executed multiple times on different
+ span events (like setting a tag) and make a positive sampling decision
+ later in the span life cycle, or even based on children spans.
+ See [README](./README.md#delayed-sampling) for more details.
+
+ There is a related minor change in behavior of the adaptive (per-operation) sampler,
+ which will no longer re-sample the trace when `span.SetOperation()` is called, i.e. the
+ operation used to make the sampling decision is always the one provided at span creation.
+
+- Add experimental tag matching sampler (#452) -- Yuri Shkuro
+
+ A sampler that can sample a trace based on a certain tag added to the root
+ span or one of its local (in-process) children. The sampler can be used with
+ another experimental `PrioritySampler` that allows multiple samplers to try
+ to make a sampling decision, in a certain priority order.

+# How to Contribute to Jaeger
+
+We'd love your help!
+
+Jaeger is [Apache 2.0 licensed](LICENSE) and accepts contributions via GitHub
+pull requests. This document outlines some of the conventions on development
+workflow, commit message formatting, contact points and other resources to make
+it easier to get your contribution accepted.
+
+We gratefully welcome improvements to documentation as well as to code.
+
+# Certificate of Origin
+
+By contributing to this project you agree to the [Developer Certificate of
+Origin](https://developercertificate.org/) (DCO). This document was created
+by the Linux Kernel community and is a simple statement that you, as a
+contributor, have the legal right to make the contribution. See the [DCO](DCO)
+file for details.
+
+## Getting Started
+
+This library uses [dep](https://golang.github.io/dep/) to manage dependencies.
+
+To get started, make sure you clone the Git repository into the correct location
+`github.com/uber/jaeger-client-go` relative to `$GOPATH`:
+
+```
+mkdir -p $GOPATH/src/github.com/uber
+cd $GOPATH/src/github.com/uber
+git clone git@github.com:jaegertracing/jaeger-client-go.git jaeger-client-go
+cd jaeger-client-go
+git submodule update --init --recursive
+```
+
+Then install dependencies and run the tests:
+
+```
+make install
+make test
+```
+
+## Imports grouping
+
+This projects follows the following pattern for grouping imports in Go files:
+ * imports from standard library
+ * imports from other projects
+ * imports from `jaeger-client-go` project
+
+For example:
+
+```go
+import (
+ "fmt"
+
+ "github.com/uber/jaeger-lib/metrics"
+ "go.uber.org/zap"
+
+ "github.com/uber/jaeger-client-go/config"
+)
+```
+
+## Making A Change
+
+*Before making any significant changes, please [open an
+issue](https://github.com/jaegertracing/jaeger-client-go/issues).* Discussing your proposed
+changes ahead of time will make the contribution process smooth for everyone.
+
+Once we've discussed your changes and you've got your code ready, make sure
+that tests are passing (`make test` or `make cover`) and open your PR. Your
+pull request is most likely to be accepted if it:
+
+* Includes tests for new functionality.
+* Follows the guidelines in [Effective
+ Go](https://golang.org/doc/effective_go.html) and the [Go team's common code
+ review comments](https://github.com/golang/go/wiki/CodeReviewComments).
+* Has a [good commit message](https://chris.beams.io/posts/git-commit/):
+ * Separate subject from body with a blank line
+ * Limit the subject line to 50 characters
+ * Capitalize the subject line
+ * Do not end the subject line with a period
+ * Use the imperative mood in the subject line
+ * Wrap the body at 72 characters
+ * Use the body to explain _what_ and _why_ instead of _how_
+* Each commit must be signed by the author ([see below](#sign-your-work)).
+
+## License
+
+By contributing your code, you agree to license your contribution under the terms
+of the [Apache License](LICENSE).
+
+If you are adding a new file it should have a header like below. The easiest
+way to add such header is to run `make fmt`.

+# Jaeger Bindings for Go OpenTracing API
+
+Instrumentation library that implements an
+[OpenTracing Go](https://github.com/opentracing/opentracing-go) Tracer for Jaeger (https://jaegertracing.io).
+
+**IMPORTANT**: The library's import path is based on its original location under `github.com/uber`. Do not try to import it as `github.com/jaegertracing`, it will not compile. We might revisit this in the next major release.
+ * :white_check_mark: `import "github.com/uber/jaeger-client-go"`
+ * :x: `import "github.com/jaegertracing/jaeger-client-go"`
+
+## How to Contribute
+
+Please see [CONTRIBUTING.md](CONTRIBUTING.md).
+
+## Installation
+
+We recommended using a dependency manager like [dep](https://golang.github.io/dep/)
+and [semantic versioning](http://semver.org/) when including this library into an application.
+For example, Jaeger backend imports this library like this:
+
+```toml
+[[constraint]]
+ name = "github.com/uber/jaeger-client-go"
+ version = "2.17"
+```
+
+If you instead want to use the latest version in `master`, you can pull it via `go get`.
+Note that during `go get` you may see build errors due to incompatible dependencies, which is why
+we recommend using semantic versions for dependencies. The error may be fixed by running
+`make install` (it will install `dep` if you don't have it):
+
+```shell
+go get -u github.com/uber/jaeger-client-go/
+cd $GOPATH/src/github.com/uber/jaeger-client-go/
+git submodule update --init --recursive
+make install
+```
+
+## Initialization
+
+See tracer initialization examples in [godoc](https://godoc.org/github.com/uber/jaeger-client-go/config#pkg-examples)
+and [config/example_test.go](./config/example_test.go).
+
+### Environment variables
+
+The tracer can be initialized with values coming from environment variables. None of the env vars are required
+and all of them can be overridden via direct setting of the property on the configuration object.
+
+Property| Description
+--- | ---
+JAEGER_SERVICE_NAME | The service name
+JAEGER_AGENT_HOST | The hostname for communicating with agent via UDP
+JAEGER_AGENT_PORT | The port for communicating with agent via UDP
+JAEGER_ENDPOINT | The HTTP endpoint for sending spans directly to a collector, i.e. http://jaeger-collector:14268/api/traces
+JAEGER_USER | Username to send as part of "Basic" authentication to the collector endpoint
+JAEGER_PASSWORD | Password to send as part of "Basic" authentication to the collector endpoint
+JAEGER_REPORTER_LOG_SPANS | Whether the reporter should also log the spans
+JAEGER_REPORTER_MAX_QUEUE_SIZE | The reporter's maximum queue size
+JAEGER_REPORTER_FLUSH_INTERVAL | The reporter's flush interval, with units, e.g. "500ms" or "2s" ([valid units][timeunits])
+JAEGER_SAMPLER_TYPE | The sampler type
+JAEGER_SAMPLER_PARAM | The sampler parameter (number)
+JAEGER_SAMPLER_MANAGER_HOST_PORT | The HTTP endpoint when using the remote sampler, i.e. http://jaeger-agent:5778/sampling
+JAEGER_SAMPLER_MAX_OPERATIONS | The maximum number of operations that the sampler will keep track of
+JAEGER_SAMPLER_REFRESH_INTERVAL | How often the remotely controlled sampler will poll jaeger-agent for the appropriate sampling strategy, with units, e.g. "1m" or "30s" ([valid units][timeunits])
+JAEGER_TAGS | A comma separated list of `name = value` tracer level tags, which get added to all reported spans. The value can also refer to an environment variable using the format `${envVarName:default}`, where the `:default` is optional, and identifies a value to be used if the environment variable cannot be found
+JAEGER_DISABLED | Whether the tracer is disabled or not. If true, the default `opentracing.NoopTracer` is used.
+JAEGER_RPC_METRICS | Whether to store RPC metrics
+
+By default, the client sends traces via UDP to the agent at `localhost:6831`. Use `JAEGER_AGENT_HOST` and
+`JAEGER_AGENT_PORT` to send UDP traces to a different `host:port`. If `JAEGER_ENDPOINT` is set, the client sends traces
+to the endpoint via `HTTP`, making the `JAEGER_AGENT_HOST` and `JAEGER_AGENT_PORT` unused. If `JAEGER_ENDPOINT` is
+secured, HTTP basic authentication can be performed by setting the `JAEGER_USER` and `JAEGER_PASSWORD` environment
+variables.
+
+### Closing the tracer via `io.Closer`
+
+The constructor function for Jaeger Tracer returns the tracer itself and an `io.Closer` instance.
+It is recommended to structure your `main()` so that it calls the `Close()` function on the closer
+before exiting, e.g.
+
+```go
+tracer, closer, err := cfg.NewTracer(...)
+defer closer.Close()
+```
+
+This is especially useful for command-line tools that enable tracing, as well as
+for the long-running apps that support graceful shutdown. For example, if your deployment
+system sends SIGTERM instead of killing the process and you trap that signal to do a graceful
+exit, then having `defer closer.Close()` ensures that all buffered spans are flushed.
+
+### Metrics & Monitoring
+
+The tracer emits a number of different metrics, defined in
+[metrics.go](metrics.go). The monitoring backend is expected to support
+tag-based metric names, e.g. instead of `statsd`-style string names
+like `counters.my-service.jaeger.spans.started.sampled`, the metrics
+are defined by a short name and a collection of key/value tags, for
+example: `name:jaeger.traces, state:started, sampled:y`. See [metrics.go](./metrics.go)
+file for the full list and descriptions of emitted metrics.
+
+The monitoring backend is represented by the `metrics.Factory` interface from package
+[`"github.com/uber/jaeger-lib/metrics"`](https://github.com/jaegertracing/jaeger-lib/tree/master/metrics). An implementation
+of that interface can be passed as an option to either the Configuration object or the Tracer
+constructor, for example:
+
+```go
+import (
+ "github.com/uber/jaeger-client-go/config"
+ "github.com/uber/jaeger-lib/metrics/prometheus"
+)
+
+ metricsFactory := prometheus.New()
+ tracer, closer, err := config.Configuration{
+ ServiceName: "your-service-name",
+ }.NewTracer(
+ config.Metrics(metricsFactory),
+ )
+```
+
+By default, a no-op `metrics.NullFactory` is used.
+
+### Logging
+
+The tracer can be configured with an optional logger, which will be
+used to log communication errors, or log spans if a logging reporter
+option is specified in the configuration. The logging API is abstracted
+by the [Logger](logger.go) interface. A logger instance implementing
+this interface can be set on the `Config` object before calling the
+`New` method.
+
+Besides the [zap](https://github.com/uber-go/zap) implementation
+bundled with this package there is also a [go-kit](https://github.com/go-kit/kit)
+one in the [jaeger-lib](https://github.com/jaegertracing/jaeger-lib) repository.
+
+## Instrumentation for Tracing
+
+Since this tracer is fully compliant with OpenTracing API 1.0,
+all code instrumentation should only use the API itself, as described
+in the [opentracing-go](https://github.com/opentracing/opentracing-go) documentation.
+
+## Features
+
+### Reporters
+
+A "reporter" is a component that receives the finished spans and reports
+them to somewhere. Under normal circumstances, the Tracer
+should use the default `RemoteReporter`, which sends the spans out of
+process via configurable "transport". For testing purposes, one can
+use an `InMemoryReporter` that accumulates spans in a buffer and
+allows to retrieve them for later verification. Also available are
+`NullReporter`, a no-op reporter that does nothing, a `LoggingReporter`
+which logs all finished spans using their `String()` method, and a
+`CompositeReporter` that can be used to combine more than one reporter
+into one, e.g. to attach a logging reporter to the main remote reporter.
+
+### Span Reporting Transports
+
+The remote reporter uses "transports" to actually send the spans out
+of process. Currently the supported transports include:
+ * [Jaeger Thrift](https://github.com/jaegertracing/jaeger-idl/blob/master/thrift/agent.thrift) over UDP or HTTP,
+ * [Zipkin Thrift](https://github.com/jaegertracing/jaeger-idl/blob/master/thrift/zipkincore.thrift) over HTTP.
+
+### Sampling
+
+The tracer does not record all spans, but only those that have the
+sampling bit set in the `flags`. When a new trace is started and a new
+unique ID is generated, a sampling decision is made whether this trace
+should be sampled. The sampling decision is propagated to all downstream
+calls via the `flags` field of the trace context. The following samplers
+are available:
+ 1. `RemotelyControlledSampler` uses one of the other simpler samplers
+ and periodically updates it by polling an external server. This
+ allows dynamic control of the sampling strategies.
+ 1. `ConstSampler` always makes the same sampling decision for all
+ trace IDs. it can be configured to either sample all traces, or
+ to sample none.
+ 1. `ProbabilisticSampler` uses a fixed sampling rate as a probability
+ for a given trace to be sampled. The actual decision is made by
+ comparing the trace ID with a random number multiplied by the
+ sampling rate.
+ 1. `RateLimitingSampler` can be used to allow only a certain fixed
+ number of traces to be sampled per second.
+
+#### Delayed sampling
+
+Version 2.20 introduced the ability to delay sampling decisions in the life cycle
+of the root span. It involves several features and architectural changes:
+ * **Shared sampling state**: the sampling state is shared across all local
+ (i.e. in-process) spans for a given trace.
+ * **New `SamplerV2` API** allows the sampler to be called at multiple points
+ in the life cycle of a span:
+ * on span creation
+ * on overwriting span operation name
+ * on setting span tags
+ * on finishing the span
+ * **Final/non-final sampling state**: the new `SamplerV2` API allows the sampler
+ to indicate if the negative sampling decision is final or not (positive sampling
+ decisions are always final). If the decision is not final, the sampler will be
+ called again on further span life cycle events, like setting tags.
+
+These new features are used in the experimental `x.TagMatchingSampler`, which
+can sample a trace based on a certain tag added to the root
+span or one of its local (in-process) children. The sampler can be used with
+another experimental `x.PrioritySampler` that allows multiple samplers to try
+to make a sampling decision, in a certain priority order.
+
+### Baggage Injection
+
+The OpenTracing spec allows for [baggage][baggage], which are key value pairs that are added
+to the span context and propagated throughout the trace. An external process can inject baggage
+by setting the special HTTP Header `jaeger-baggage` on a request:
+
+```sh
+curl -H "jaeger-baggage: key1=value1, key2=value2" http://myhost.com
+```
+
+Baggage can also be programatically set inside your service:
+
+```go
+if span := opentracing.SpanFromContext(ctx); span != nil {
+ span.SetBaggageItem("key", "value")
+}
+```
+
+Another service downstream of that can retrieve the baggage in a similar way:
+
+```go
+if span := opentracing.SpanFromContext(ctx); span != nil {
+ val := span.BaggageItem("key")
+ println(val)
+}
+```
+
+### Debug Traces (Forced Sampling)
+
+#### Programmatically
+
+The OpenTracing API defines a `sampling.priority` standard tag that
+can be used to affect the sampling of a span and its children:
+
+```go
+import (
+ "github.com/opentracing/opentracing-go"
+ "github.com/opentracing/opentracing-go/ext"
+)
+
+span := opentracing.SpanFromContext(ctx)
+ext.SamplingPriority.Set(span, 1)
+```
+
+#### Via HTTP Headers
+
+Jaeger Tracer also understands a special HTTP Header `jaeger-debug-id`,
+which can be set in the incoming request, e.g.
+
+```sh
+curl -H "jaeger-debug-id: some-correlation-id" http://myhost.com
+```
+
+When Jaeger sees this header in the request that otherwise has no
+tracing context, it ensures that the new trace started for this
+request will be sampled in the "debug" mode (meaning it should survive
+all downsampling that might happen in the collection pipeline), and the
+root span will have a tag as if this statement was executed:
+
+```go
+span.SetTag("jaeger-debug-id", "some-correlation-id")
+```
+
+This allows using Jaeger UI to find the trace by this tag.
+
+### Zipkin HTTP B3 compatible header propagation
+
+Jaeger Tracer supports Zipkin B3 Propagation HTTP headers, which are used
+by a lot of Zipkin tracers. This means that you can use Jaeger in conjunction with e.g. [these OpenZipkin tracers](https://github.com/openzipkin).
+
+However it is not the default propagation format, see [here](zipkin/README.md#NewZipkinB3HTTPHeaderPropagator) how to set it up.
+
+## SelfRef
+
+Jaeger Tracer supports an additional [span reference][] type call `Self`, which was proposed
+to the OpenTracing Specification (https://github.com/opentracing/specification/issues/81)
+but not yet accepted. This allows the caller to provide an already created `SpanContext`
+when starting a new span. The `Self` reference bypasses trace and span id generation,
+as well as sampling decisions (i.e. the sampling bit in the `SpanContext.flags` must be
+set appropriately by the caller).
+
+The `Self` reference supports the following use cases:
+ * the ability to provide externally generated trace and span IDs
+ * appending data to the same span from different processes, such as loading and continuing spans/traces from offline (ie log-based) storage
+
+Usage requires passing in a `SpanContext` and the `jaeger.Self` reference type:
+```
+span := tracer.StartSpan(
+ "continued_span",
+ jaeger.SelfRef(yourSpanContext),
+)
+...
+defer span.Finish()
+```

+// A trace is a series of spans (often RPC calls) which form a latency tree.
+//
+// The root span is where trace_id = id and parent_id = Nil. The root span is
+// usually the longest interval in the trace, starting with a SERVER_RECV
+// annotation and ending with a SERVER_SEND.
+//
+// Attributes:
+// - TraceID
+// - Name: Span name in lowercase, rpc method for example
+//
+// Conventionally, when the span name isn't known, name = "unknown".
+// - ID
+// - ParentID
+// - Annotations
+// - BinaryAnnotations
+// - Debug
+// - Timestamp: Microseconds from epoch of the creation of this span.
+//
+// This value should be set directly by instrumentation, using the most
+// precise value possible. For example, gettimeofday or syncing nanoTime
+// against a tick of currentTimeMillis.
+//
+// For compatibility with instrumentation that precede this field, collectors
+// or span stores can derive this via Annotation.timestamp.
+// For example, SERVER_RECV.timestamp or CLIENT_SEND.timestamp.
+//
+// This field is optional for compatibility with old data: first-party span
+// stores are expected to support this at time of introduction.
+// - Duration: Measurement of duration in microseconds, used to support queries.
+//
+// This value should be set directly, where possible. Doing so encourages
+// precise measurement decoupled from problems of clocks, such as skew or NTP
+// updates causing time to move backwards.
+//
+// For compatibility with instrumentation that precede this field, collectors
+// or span stores can derive this by subtracting Annotation.timestamp.
+// For example, SERVER_SEND.timestamp - SERVER_RECV.timestamp.
+//
+// If this field is persisted as unset, zipkin will continue to work, except
+// duration query support will be implementation-specific. Similarly, setting
+// this field non-atomically is implementation-specific.
+//
+// This field is i64 vs i32 to support spans longer than 35 minutes.
+// - TraceIDHigh: Optional unique 8-byte additional identifier for a trace. If non zero, this
+// means the trace uses 128 bit traceIds instead of 64 bit.
