-# OpenTracing API for Go
-
-This package is a Go platform API for OpenTracing.
-
-## Required Reading
-
-In order to understand the Go platform API, one must first be familiar with the
-[OpenTracing project](https://opentracing.io) and
-[terminology](https://opentracing.io/specification/) more specifically.
-
-## API overview for those adding instrumentation
-
-Everyday consumers of this `opentracing` package really only need to worry
-about a couple of key abstractions: the `StartSpan` function, the `Span`
-interface, and binding a `Tracer` at `main()`-time. Here are code snippets
-demonstrating some important use cases.
-
-#### Singleton initialization
-
-The simplest starting point is `./default_tracer.go`. As early as possible, call
-
-```go
-    import "github.com/opentracing/opentracing-go"
-    import ".../some_tracing_impl"
-
-    func main() {
-        opentracing.SetGlobalTracer(
-            // tracing impl specific:
-            some_tracing_impl.New(...),
-        )
-        ...
-    }
-```
-
-#### Non-Singleton initialization
-
-If you prefer direct control to singletons, manage ownership of the
-`opentracing.Tracer` implementation explicitly.
-
-#### Creating a Span given an existing Go `context.Context`
-
-If you use `context.Context` in your application, OpenTracing's Go library will
-happily rely on it for `Span` propagation. To start a new (blocking child)
-`Span`, you can use `StartSpanFromContext`.
-
-```go
-    func xyz(ctx context.Context, ...) {
-        ...
-        span, ctx := opentracing.StartSpanFromContext(ctx, "operation_name")
-        defer span.Finish()
-        span.LogFields(
-            log.String("event", "soft error"),
-            log.String("type", "cache timeout"),
-            log.Int("waited.millis", 1500))
-        ...
-    }
-```
-
-#### Starting an empty trace by creating a "root span"
-
-It's always possible to create a "root" `Span` with no parent or other causal
-reference.
-
-```go
-    func xyz() {
-        ...
-        sp := opentracing.StartSpan("operation_name")
-        defer sp.Finish()
-        ...
-    }
-```
-
-#### Creating a (child) Span given an existing (parent) Span
-
-```go
-    func xyz(parentSpan opentracing.Span, ...) {
-        ...
-        sp := opentracing.StartSpan(
-            "operation_name",
-            opentracing.ChildOf(parentSpan.Context()))
-        defer sp.Finish()
-        ...
-    }
-```
-
-#### Serializing to the wire
-
-```go
-    func makeSomeRequest(ctx context.Context) ... {
-        if span := opentracing.SpanFromContext(ctx); span != nil {
-            httpClient := &http.Client{}
-            httpReq, _ := http.NewRequest("GET", "http://myservice/", nil)
-
-            // Transmit the span's TraceContext as HTTP headers on our
-            // outbound request.
-            opentracing.GlobalTracer().Inject(
-                span.Context(),
-                opentracing.HTTPHeaders,
-                opentracing.HTTPHeadersCarrier(httpReq.Header))
-
-            resp, err := httpClient.Do(httpReq)
-            ...
-        }
-        ...
-    }
-```
-
-#### Deserializing from the wire
-
-```go
-    http.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
-        var serverSpan opentracing.Span
-        appSpecificOperationName := ...
-        wireContext, err := opentracing.GlobalTracer().Extract(
-            opentracing.HTTPHeaders,
-            opentracing.HTTPHeadersCarrier(req.Header))
-        if err != nil {
-            // Optionally record something about err here
-        }
-
-        // Create the span referring to the RPC client if available.
-        // If wireContext == nil, a root span will be created.
-        serverSpan = opentracing.StartSpan(
-            appSpecificOperationName,
-            ext.RPCServerOption(wireContext))
-
-        defer serverSpan.Finish()
-
-        ctx := opentracing.ContextWithSpan(context.Background(), serverSpan)
-        ...
-    }
-```
-
-#### Conditionally capture a field using `log.Noop`
-
-In some situations, you may want to dynamically decide whether or not
-to log a field.  For example, you may want to capture additional data,
-such as a customer ID, in non-production environments:
-
-```go
-    func Customer(order *Order) log.Field {
-        if os.Getenv("ENVIRONMENT") == "dev" {
-            return log.String("customer", order.Customer.ID)
-        }
-        return log.Noop()
-    }
-```
-
-#### Goroutine-safety
-
-The entire public API is goroutine-safe and does not require external
-synchronization.
-
-## API pointers for those implementing a tracing system
-
-Tracing system implementors may be able to reuse or copy-paste-modify the `basictracer` package, found [here](https://github.com/opentracing/basictracer-go). In particular, see `basictracer.New(...)`.
-
-## API compatibility
-
-For the time being, "mild" backwards-incompatible changes may be made without changing the major version number. As OpenTracing and `opentracing-go` mature, backwards compatibility will become more of a priority.
-
-## Tracer test suite
-
-A test suite is available in the [harness](https://godoc.org/github.com/opentracing/opentracing-go/harness) package that can assist Tracer implementors to assert that their Tracer is working correctly.

-## 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()
-```
