Unfortunately everything I've seen so far has a high chance of +breaking your application. + +The main problem is that a `http.ResponseWriter` often implements additional +interfaces such as `http.Flusher`, `http.CloseNotifier`, `http.Hijacker`, `http.Pusher`, and +`io.ReaderFrom`. So the naive approach of just wrapping `http.ResponseWriter` +in your own struct that also implements the `http.ResponseWriter` interface +will hide the additional interfaces mentioned above. This has a high change of +introducing subtle bugs into any non-trivial application. + +Another approach I've seen people take is to return a struct that implements +all of the interfaces above. However, that's also problematic, because it's +difficult to fake some of these interfaces behaviors when the underlying +`http.ResponseWriter` doesn't have an implementation. It's also dangerous, +because an application may choose to operate differently, merely because it +detects the presence of these additional interfaces. + +This package solves this problem by checking which additional interfaces a +`http.ResponseWriter` implements, returning a wrapped version implementing the +exact same set of interfaces. + +Additionally this package properly handles edge cases such as `WriteHeader` not +being called, or called more than once, as well as concurrent calls to +`http.ResponseWriter` methods, and even calls happening after the wrapped +`ServeHTTP` has already returned. + +Unfortunately this package is not perfect either. It's possible that it is +still missing some interfaces provided by the go core (let me know if you find +one), and it won't work for applications adding their own interfaces into the +mix. You can however use `httpsnoop.Unwrap(w)` to access the underlying +`http.ResponseWriter` and type-assert the result to its other interfaces. + +However, hopefully the explanation above has sufficiently scared you of rolling +your own solution to this problem. httpsnoop may still break your application, +but at least it tries to avoid it as much as possible. + +Anyway, the real problem here is that smuggling additional interfaces inside +`http.ResponseWriter` is a problematic design choice, but it probably goes as +deep as the Go language specification itself. But that's okay, I still prefer +Go over the alternatives ;). + +## Performance + +``` +BenchmarkBaseline-8 20000 94912 ns/op +BenchmarkCaptureMetrics-8 20000 95461 ns/op +``` + +As you can see, using `CaptureMetrics` on a vanilla http.Handler introduces an +overhead of ~500 ns per http request on my machine.

Conflicts between the existing platform specific provider image match configuration and this list will be handled by the following precedence rule: credentials from built-in kubelet providers (e.g., ECR, GCR, ACR) take precedence over those from the CRIOCredentialProviderConfig when both match the same image. To avoid uncertainty, it is recommended to avoid configuring your private image patterns to overlap with existing platform specific provider config(e.g., the entries from https://github.com/openshift/machine-config-operator/blob/main/templates/common/aws/files/etc-kubernetes-credential-providers-ecr-credential-provider.yaml).

A global wildcard '*' (matching any domain) is not allowed. Wildcards may replace an entire hostname label (e.g., *.example.com), but they cannot appear within a label (e.g., f*oo.example.com) and are not allowed in the port or path. For example, 'example.*.com' is valid, but 'exa*mple.*.com' is not.

(#2502) +- Add Go 1.18 to our compatibility tests. (#2679) +- Allow configuring the Sampler with the `OTEL_TRACES_SAMPLER` and `OTEL_TRACES_SAMPLER_ARG` environment variables. (#2305, #2517) +- Add the `metric/global` for obtaining and setting the global `MeterProvider`. (#2660) + +### Changed + +- The metrics API has been significantly changed to match the revised OpenTelemetry specification. + High-level changes include: + + - Synchronous and asynchronous instruments are now handled by independent `InstrumentProvider`s. + These `InstrumentProvider`s are managed with a `Meter`. + - Synchronous and asynchronous instruments are grouped into their own packages based on value types. + - Asynchronous callbacks can now be registered with a `Meter`. + + Be sure to check out the metric module documentation for more information on how to use the revised API. (#2587, #2660) + +### Fixed + +- Fallback to general attribute limits when span specific ones are not set in the environment. (#2675, #2677) + +## [1.5.0] - 2022-03-16 + +### Added + +- Log the Exporters configuration in the TracerProviders message. (#2578) +- Added support to configure the span limits with environment variables. + The following environment variables are supported. (#2606, #2637) + - `OTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT` + - `OTEL_SPAN_ATTRIBUTE_COUNT_LIMIT` + - `OTEL_SPAN_EVENT_COUNT_LIMIT` + - `OTEL_EVENT_ATTRIBUTE_COUNT_LIMIT` + - `OTEL_SPAN_LINK_COUNT_LIMIT` + - `OTEL_LINK_ATTRIBUTE_COUNT_LIMIT` + + If the provided environment variables are invalid (negative), the default values would be used. +- Rename the `gc` runtime name to `go` (#2560) +- Add resource container ID detection. (#2418) +- Add span attribute value length limit. + The new `AttributeValueLengthLimit` field is added to the `"go.opentelemetry.io/otel/sdk/trace".SpanLimits` type to configure this limit for a `TracerProvider`. + The default limit for this resource is "unlimited". (#2637) +- Add the `WithRawSpanLimits` option to `go.opentelemetry.io/otel/sdk/trace`. + This option replaces the `WithSpanLimits` option. + Zero or negative values will not be changed to the default value like `WithSpanLimits` does. + Setting a limit to zero will effectively disable the related resource it limits and setting to a negative value will mean that resource is unlimited. + Consequentially, limits should be constructed using `NewSpanLimits` and updated accordingly. (#2637) + +### Changed + +- Drop oldest tracestate `Member` when capacity is reached. (#2592) +- Add event and link drop counts to the exported data from the `oltptrace` exporter. (#2601) +- Unify path cleaning functionally in the `otlpmetric` and `otlptrace` configuration. (#2639) +- Change the debug message from the `sdk/trace.BatchSpanProcessor` to reflect the count is cumulative. (#2640) +- Introduce new internal `envconfig` package for OTLP exporters. (#2608) +- If `http.Request.Host` is empty, fall back to use `URL.Host` when populating `http.host` in the `semconv` packages. (#2661) + +### Fixed + +- Remove the OTLP trace exporter limit of SpanEvents when exporting. (#2616) +- Default to port `4318` instead of `4317` for the `otlpmetrichttp` and `otlptracehttp` client. (#2614, #2625) +- Unlimited span limits are now supported (negative values). (#2636, #2637) + +### Deprecated + +- Deprecated `"go.opentelemetry.io/otel/sdk/trace".WithSpanLimits`. + Use `WithRawSpanLimits` instead. + That option allows setting unlimited and zero limits, this option does not. + This option will be kept until the next major version incremented release. (#2637) + +## [1.4.1] - 2022-02-16 + +### Fixed + +- Fix race condition in reading the dropped spans number for the `BatchSpanProcessor`. (#2615) + +## [1.4.0] - 2022-02-11 + +### Added + +- Use `OTEL_EXPORTER_ZIPKIN_ENDPOINT` environment variable to specify zipkin collector endpoint. (#2490) +- Log the configuration of `TracerProvider`s, and `Tracer`s for debugging. + To enable use a logger with Verbosity (V level) `>=1`. (#2500) +- Added support to configure the batch span-processor with environment variables. + The following environment variables are used. (#2515) + - `OTEL_BSP_SCHEDULE_DELAY` + - `OTEL_BSP_EXPORT_TIMEOUT` + - `OTEL_BSP_MAX_QUEUE_SIZE`. + - `OTEL_BSP_MAX_EXPORT_BATCH_SIZE` + +### Changed + +- Zipkin exporter exports `Resource` attributes in the `Tags` field. (#2589) + +### Deprecated + +- Deprecate module the `go.opentelemetry.io/otel/sdk/export/metric`. + Use the `go.opentelemetry.io/otel/sdk/metric` module instead. (#2382) +- Deprecate `"go.opentelemetry.io/otel/sdk/metric".AtomicFieldOffsets`. (#2445) + +### Fixed + +- Fixed the instrument kind for noop async instruments to correctly report an implementation. (#2461) +- Fix UDP packets overflowing with Jaeger payloads. (#2489, #2512) +- Change the `otlpmetric.Client` interface's `UploadMetrics` method to accept a single `ResourceMetrics` instead of a slice of them. (#2491) +- Specify explicit buckets in Prometheus example, fixing issue where example only has `+inf` bucket. (#2419, #2493) +- W3C baggage will now decode urlescaped values. (#2529) +- Baggage members are now only validated once, when calling `NewMember` and not also when adding it to the baggage itself. (#2522) +- The order attributes are dropped from spans in the `go.opentelemetry.io/otel/sdk/trace` package when capacity is reached is fixed to be in compliance with the OpenTelemetry specification. + Instead of dropping the least-recently-used attribute, the last added attribute is dropped. + This drop order still only applies to attributes with unique keys not already contained in the span. + If an attribute is added with a key already contained in the span, that attribute is updated to the new value being added. (#2576) + +### Removed + +- Updated `go.opentelemetry.io/proto/otlp` from `v0.11.0` to `v0.12.0`. This version removes a number of deprecated methods. (#2546) + - [`Metric.GetIntGauge()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntGauge) + - [`Metric.GetIntHistogram()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntHistogram) + - [`Metric.GetIntSum()`](https://pkg.go.dev/go.opentelemetry.io/proto/otlp@v0.11.0/metrics/v1#Metric.GetIntSum) + +## [1.3.0] - 2021-12-10 + +### ⚠️ Notice ⚠️ + +We have updated the project minimum supported Go version to 1.16 + +### Added + +- Added an internal Logger. + This can be used by the SDK and API to provide users with feedback of the internal state. + To enable verbose logs configure the logger which will print V(1) logs. For debugging information configure to print V(5) logs. (#2343) +- Add the `WithRetry` `Option` and the `RetryConfig` type to the `go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp` package to specify retry behavior consistently. (#2425) +- Add `SpanStatusFromHTTPStatusCodeAndSpanKind` to all `semconv` packages to return a span status code similar to `SpanStatusFromHTTPStatusCode`, but exclude `4XX` HTTP errors as span errors if the span is of server kind. (#2296) + +### Changed + +- The `"go.opentelemetry.io/otel/exporter/otel/otlptrace/otlptracegrpc".Client` now uses the underlying gRPC `ClientConn` to handle name resolution, TCP connection establishment (with retries and backoff) and TLS handshakes, and handling errors on established connections by re-resolving the name and reconnecting. (#2329) +- The `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetricgrpc".Client` now uses the underlying gRPC `ClientConn` to handle name resolution, TCP connection establishment (with retries and backoff) and TLS handshakes, and handling errors on established connections by re-resolving the name and reconnecting. (#2425) +- The `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetricgrpc".RetrySettings` type is renamed to `RetryConfig`. (#2425) +- The `go.opentelemetry.io/otel/exporter/otel/*` gRPC exporters now default to using the host's root CA set if none are provided by the user and `WithInsecure` is not specified. (#2432) +- Change `resource.Default` to be evaluated the first time it is called, rather than on import. This allows the caller the option to update `OTEL_RESOURCE_ATTRIBUTES` first, such as with `os.Setenv`. (#2371) + +### Fixed + +- The `go.opentelemetry.io/otel/exporter/otel/*` exporters are updated to handle per-signal and universal endpoints according to the OpenTelemetry specification. + Any per-signal endpoint set via an `OTEL_EXPORTER_OTLP__ENDPOINT` environment variable is now used without modification of the path. + When `OTEL_EXPORTER_OTLP_ENDPOINT` is set, if it contains a path, that path is used as a base path which per-signal paths are appended to. (#2433) +- Basic metric controller updated to use sync.Map to avoid blocking calls (#2381) +- The `go.opentelemetry.io/otel/exporter/jaeger` correctly sets the `otel.status_code` value to be a string of `ERROR` or `OK` instead of an integer code. (#2439, #2440) + +### Deprecated + +- Deprecated the `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp".WithMaxAttempts` `Option`, use the new `WithRetry` `Option` instead. (#2425) +- Deprecated the `"go.opentelemetry.io/otel/exporter/otel/otlpmetric/otlpmetrichttp".WithBackoff` `Option`, use the new `WithRetry` `Option` instead. (#2425) + +### Removed + +- Remove the metric Processor's ability to convert cumulative to delta aggregation temporality. (#2350) +- Remove the metric Bound Instruments interface and implementations. (#2399) +- Remove the metric MinMaxSumCount kind aggregation and the corresponding OTLP export path. (#2423) +- Metric SDK removes the "exact" aggregator for histogram instruments, as it performed a non-standard aggregation for OTLP export (creating repeated Gauge points) and worked its way into a number of confusing examples. (#2348) + +## [1.2.0] - 2021-11-12 + +### Changed + +- Metric SDK `export.ExportKind`, `export.ExportKindSelector` types have been renamed to `aggregation.Temporality` and `aggregation.TemporalitySelector` respectively to keep in line with current specification and protocol along with built-in selectors (e.g., `aggregation.CumulativeTemporalitySelector`, ...). (#2274) +- The Metric `Exporter` interface now requires a `TemporalitySelector` method instead of an `ExportKindSelector`. (#2274) +- Metrics API cleanup. The `metric/sdkapi` package has been created to relocate the API-to-SDK interface: + - The following interface types simply moved from `metric` to `metric/sdkapi`: `Descriptor`, `MeterImpl`, `InstrumentImpl`, `SyncImpl`, `BoundSyncImpl`, `AsyncImpl`, `AsyncRunner`, `AsyncSingleRunner`, and `AsyncBatchRunner` + - The following struct types moved and are replaced with type aliases, since they are exposed to the user: `Observation`, `Measurement`. + - The No-op implementations of sync and async instruments are no longer exported, new functions `sdkapi.NewNoopAsyncInstrument()` and `sdkapi.NewNoopSyncInstrument()` are provided instead. (#2271) +- Update the SDK `BatchSpanProcessor` to export all queued spans when `ForceFlush` is called. (#2080, #2335) + +### Added + +- Add the `"go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc".WithGRPCConn` option so the exporter can reuse an existing gRPC connection. (#2002) +- Added a new `schema` module to help parse Schema Files in OTEP 0152 format. (#2267) +- Added a new `MapCarrier` to the `go.opentelemetry.io/otel/propagation` package to hold propagated cross-cutting concerns as a `map[string]string` held in memory. (#2334) + +## [1.1.0] - 2021-10-27 + +### Added + +- Add the `"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc".WithGRPCConn` option so the exporter can reuse an existing gRPC connection. (#2002) +- Add the `go.opentelemetry.io/otel/semconv/v1.7.0` package. + The package contains semantic conventions from the `v1.7.0` version of the OpenTelemetry specification. (#2320) +- Add the `go.opentelemetry.io/otel/semconv/v1.6.1` package. + The package contains semantic conventions from the `v1.6.1` version of the OpenTelemetry specification. (#2321) +- Add the `go.opentelemetry.io/otel/semconv/v1.5.0` package. + The package contains semantic conventions from the `v1.5.0` version of the OpenTelemetry specification. (#2322) + - When upgrading from the `semconv/v1.4.0` package note the following name changes: + - `K8SReplicasetUIDKey` -> `K8SReplicaSetUIDKey` + - `K8SReplicasetNameKey` -> `K8SReplicaSetNameKey` + - `K8SStatefulsetUIDKey` -> `K8SStatefulSetUIDKey` + - `k8SStatefulsetNameKey` -> `K8SStatefulSetNameKey` + - `K8SDaemonsetUIDKey` -> `K8SDaemonSetUIDKey` + - `K8SDaemonsetNameKey` -> `K8SDaemonSetNameKey` + +### Changed + +- Links added to a span will be dropped by the SDK if they contain an invalid span context (#2275). + +### Fixed + +- The `"go.opentelemetry.io/otel/semconv/v1.4.0".HTTPServerAttributesFromHTTPRequest` now correctly only sets the HTTP client IP attribute even if the connection was routed with proxies and there are multiple addresses in the `X-Forwarded-For` header. (#2282, #2284) +- The `"go.opentelemetry.io/otel/semconv/v1.4.0".NetAttributesFromHTTPRequest` function correctly handles IPv6 addresses as IP addresses and sets the correct net peer IP instead of the net peer hostname attribute. (#2283, #2285) +- The simple span processor shutdown method deterministically returns the exporter error status if it simultaneously finishes when the deadline is reached. (#2290, #2289) + +## [1.0.1] - 2021-10-01 + +### Fixed + +- json stdout exporter no longer crashes due to concurrency bug. (#2265) + +## [Metrics 0.24.0] - 2021-10-01 + +### Changed + +- NoopMeterProvider is now private and NewNoopMeterProvider must be used to obtain a noopMeterProvider. (#2237) +- The Metric SDK `Export()` function takes a new two-level reader interface for iterating over results one instrumentation library at a time. (#2197) + - The former `"go.opentelemetry.io/otel/sdk/export/metric".CheckpointSet` is renamed `Reader`. + - The new interface is named `"go.opentelemetry.io/otel/sdk/export/metric".InstrumentationLibraryReader`. + +## [1.0.0] - 2021-09-20 + +This is the first stable release for the project. +This release includes an API and SDK for the tracing signal that will comply with the stability guarantees defined by the projects [versioning policy](./VERSIONING.md). + +### Added + +- OTLP trace exporter now sets the `SchemaURL` field in the exported telemetry if the Tracer has `WithSchemaURL` option. (#2242) + +### Fixed + +- Slice-valued attributes can correctly be used as map keys. (#2223) + +### Removed + +- Removed the `"go.opentelemetry.io/otel/exporters/zipkin".WithSDKOptions` function. (#2248) +- Removed the deprecated package `go.opentelemetry.io/otel/oteltest`. (#2234) +- Removed the deprecated package `go.opentelemetry.io/otel/bridge/opencensus/utils`. (#2233) +- Removed deprecated functions, types, and methods from `go.opentelemetry.io/otel/attribute` package. + Use the typed functions and methods added to the package instead. (#2235) + - The `Key.Array` method is removed. + - The `Array` function is removed. + - The `Any` function is removed. + - The `ArrayValue` function is removed. + - The `AsArray` function is removed. + +## [1.0.0-RC3] - 2021-09-02 + +### Added + +- Added `ErrorHandlerFunc` to use a function as an `"go.opentelemetry.io/otel".ErrorHandler`. (#2149) +- Added `"go.opentelemetry.io/otel/trace".WithStackTrace` option to add a stack trace when using `span.RecordError` or when panic is handled in `span.End`. (#2163) +- Added typed slice attribute types and functionality to the `go.opentelemetry.io/otel/attribute` package to replace the existing array type and functions. (#2162) + - `BoolSlice`, `IntSlice`, `Int64Slice`, `Float64Slice`, and `StringSlice` replace the use of the `Array` function in the package. +- Added the `go.opentelemetry.io/otel/example/fib` example package. + Included is an example application that computes Fibonacci numbers. (#2203) + +### Changed + +- Metric instruments have been renamed to match the (feature-frozen) metric API specification: + - ValueRecorder becomes Histogram + - ValueObserver becomes Gauge + - SumObserver becomes CounterObserver + - UpDownSumObserver becomes UpDownCounterObserver + The API exported from this project is still considered experimental. (#2202) +- Metric SDK/API implementation type `InstrumentKind` moves into `sdkapi` sub-package. (#2091) +- The Metrics SDK export record no longer contains a Resource pointer, the SDK `"go.opentelemetry.io/otel/sdk/trace/export/metric".Exporter.Export()` function for push-based exporters now takes a single Resource argument, pull-based exporters use `"go.opentelemetry.io/otel/sdk/metric/controller/basic".Controller.Resource()`. (#2120) +- The JSON output of the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` is harmonized now such that the output is "plain" JSON objects after each other of the form `{ ... } { ... } { ... }`. Earlier the JSON objects describing a span were wrapped in a slice for each `Exporter.ExportSpans` call, like `[ { ... } ][ { ... } { ... } ]`. Outputting JSON object directly after each other is consistent with JSON loggers, and a bit easier to parse and read. (#2196) +- Update the `NewTracerConfig`, `NewSpanStartConfig`, `NewSpanEndConfig`, and `NewEventConfig` function in the `go.opentelemetry.io/otel/trace` package to return their respective configurations as structs instead of pointers to the struct. (#2212) + +### Deprecated + +- The `go.opentelemetry.io/otel/bridge/opencensus/utils` package is deprecated. + All functionality from this package now exists in the `go.opentelemetry.io/otel/bridge/opencensus` package. + The functions from that package should be used instead. (#2166) +- The `"go.opentelemetry.io/otel/attribute".Array` function and the related `ARRAY` value type is deprecated. + Use the typed `*Slice` functions and types added to the package instead. (#2162) +- The `"go.opentelemetry.io/otel/attribute".Any` function is deprecated. + Use the typed functions instead. (#2181) +- The `go.opentelemetry.io/otel/oteltest` package is deprecated. + The `"go.opentelemetry.io/otel/sdk/trace/tracetest".SpanRecorder` can be registered with the default SDK (`go.opentelemetry.io/otel/sdk/trace`) as a `SpanProcessor` and used as a replacement for this deprecated package. (#2188) + +### Removed + +- Removed metrics test package `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#2105) + +### Fixed + +- The `fromEnv` detector no longer throws an error when `OTEL_RESOURCE_ATTRIBUTES` environment variable is not set or empty. (#2138) +- Setting the global `ErrorHandler` with `"go.opentelemetry.io/otel".SetErrorHandler` multiple times is now supported. (#2160, #2140) +- The `"go.opentelemetry.io/otel/attribute".Any` function now supports `int32` values. (#2169) +- Multiple calls to `"go.opentelemetry.io/otel/sdk/metric/controller/basic".WithResource()` are handled correctly, and when no resources are provided `"go.opentelemetry.io/otel/sdk/resource".Default()` is used. (#2120) +- The `WithoutTimestamps` option for the `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` exporter causes the exporter to correctly omit timestamps. (#2195) +- Fixed typos in resources.go. (#2201) + +## [1.0.0-RC2] - 2021-07-26 + +### Added + +- Added `WithOSDescription` resource configuration option to set OS (Operating System) description resource attribute (`os.description`). (#1840) +- Added `WithOS` resource configuration option to set all OS (Operating System) resource attributes at once. (#1840) +- Added the `WithRetry` option to the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package. + This option is a replacement for the removed `WithMaxAttempts` and `WithBackoff` options. (#2095) +- Added API `LinkFromContext` to return Link which encapsulates SpanContext from provided context and also encapsulates attributes. (#2115) +- Added a new `Link` type under the SDK `otel/sdk/trace` package that counts the number of attributes that were dropped for surpassing the `AttributePerLinkCountLimit` configured in the Span's `SpanLimits`. + This new type replaces the equal-named API `Link` type found in the `otel/trace` package for most usages within the SDK. + For example, instances of this type are now returned by the `Links()` function of `ReadOnlySpan`s provided in places like the `OnEnd` function of `SpanProcessor` implementations. (#2118) +- Added the `SpanRecorder` type to the `go.opentelemetry.io/otel/skd/trace/tracetest` package. + This type can be used with the default SDK as a `SpanProcessor` during testing. (#2132) + +### Changed + +- The `SpanModels` function is now exported from the `go.opentelemetry.io/otel/exporters/zipkin` package to convert OpenTelemetry spans into Zipkin model spans. (#2027) +- Rename the `"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc".RetrySettings` to `RetryConfig`. (#2095) + +### Deprecated + +- The `TextMapCarrier` and `TextMapPropagator` from the `go.opentelemetry.io/otel/oteltest` package and their associated creation functions (`TextMapCarrier`, `NewTextMapPropagator`) are deprecated. (#2114) +- The `Harness` type from the `go.opentelemetry.io/otel/oteltest` package and its associated creation function, `NewHarness` are deprecated and will be removed in the next release. (#2123) +- The `TraceStateFromKeyValues` function from the `go.opentelemetry.io/otel/oteltest` package is deprecated. + Use the `trace.ParseTraceState` function instead. (#2122) + +### Removed + +- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/jaeger`. (#2020) +- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/zipkin`. (#2020) +- Removed the `"go.opentelemetry.io/otel/sdk/resource".WithBuiltinDetectors` function. + The explicit `With*` options for every built-in detector should be used instead. (#2026 #2097) +- Removed the `WithMaxAttempts` and `WithBackoff` options from the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package. + The retry logic of the package has been updated to match the `otlptracegrpc` package and accordingly a `WithRetry` option is added that should be used instead. (#2095) +- Removed `DroppedAttributeCount` field from `otel/trace.Link` struct. (#2118) + +### Fixed + +- When using WithNewRoot, don't use the parent context for making sampling decisions. (#2032) +- `oteltest.Tracer` now creates a valid `SpanContext` when using `WithNewRoot`. (#2073) +- OS type detector now sets the correct `dragonflybsd` value for DragonFly BSD. (#2092) +- The OTel span status is correctly transformed into the OTLP status in the `go.opentelemetry.io/otel/exporters/otlp/otlptrace` package. + This fix will by default set the status to `Unset` if it is not explicitly set to `Ok` or `Error`. (#2099 #2102) +- The `Inject` method for the `"go.opentelemetry.io/otel/propagation".TraceContext` type no longer injects empty `tracestate` values. (#2108) +- Use `6831` as default Jaeger agent port instead of `6832`. (#2131) + +## [Experimental Metrics v0.22.0] - 2021-07-19 + +### Added + +- Adds HTTP support for OTLP metrics exporter. (#2022) + +### Removed + +- Removed the deprecated package `go.opentelemetry.io/otel/exporters/metric/prometheus`. (#2020) + +## [1.0.0-RC1] / 0.21.0 - 2021-06-18 + +With this release we are introducing a split in module versions. The tracing API and SDK are entering the `v1.0.0` Release Candidate phase with `v1.0.0-RC1` +while the experimental metrics API and SDK continue with `v0.x` releases at `v0.21.0`. Modules at major version 1 or greater will not depend on modules +with major version 0. + +### Added + +- Adds `otlpgrpc.WithRetry`option for configuring the retry policy for transient errors on the otlp/gRPC exporter. (#1832) + - The following status codes are defined as transient errors: + | gRPC Status Code | Description | + | ---------------- | ----------- | + | 1 | Cancelled | + | 4 | Deadline Exceeded | + | 8 | Resource Exhausted | + | 10 | Aborted | + | 10 | Out of Range | + | 14 | Unavailable | + | 15 | Data Loss | +- Added `Status` type to the `go.opentelemetry.io/otel/sdk/trace` package to represent the status of a span. (#1874) +- Added `SpanStub` type and its associated functions to the `go.opentelemetry.io/otel/sdk/trace/tracetest` package. + This type can be used as a testing replacement for the `SpanSnapshot` that was removed from the `go.opentelemetry.io/otel/sdk/trace` package. (#1873) +- Adds support for scheme in `OTEL_EXPORTER_OTLP_ENDPOINT` according to the spec. (#1886) +- Adds `trace.WithSchemaURL` option for configuring the tracer with a Schema URL. (#1889) +- Added an example of using OpenTelemetry Go as a trace context forwarder. (#1912) +- `ParseTraceState` is added to the `go.opentelemetry.io/otel/trace` package. + It can be used to decode a `TraceState` from a `tracestate` header string value. (#1937) +- Added `Len` method to the `TraceState` type in the `go.opentelemetry.io/otel/trace` package. + This method returns the number of list-members the `TraceState` holds. (#1937) +- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace` that defines a trace exporter that uses a `otlptrace.Client` to send data. + Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` implementing a gRPC `otlptrace.Client` and offers convenience functions, `NewExportPipeline` and `InstallNewPipeline`, to setup and install a `otlptrace.Exporter` in tracing .(#1922) +- Added `Baggage`, `Member`, and `Property` types to the `go.opentelemetry.io/otel/baggage` package along with their related functions. (#1967) +- Added `ContextWithBaggage`, `ContextWithoutBaggage`, and `FromContext` functions to the `go.opentelemetry.io/otel/baggage` package. + These functions replace the `Set`, `Value`, `ContextWithValue`, `ContextWithoutValue`, and `ContextWithEmpty` functions from that package and directly work with the new `Baggage` type. (#1967) +- The `OTEL_SERVICE_NAME` environment variable is the preferred source for `service.name`, used by the environment resource detector if a service name is present both there and in `OTEL_RESOURCE_ATTRIBUTES`. (#1969) +- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` implementing an HTTP `otlptrace.Client` and offers convenience functions, `NewExportPipeline` and `InstallNewPipeline`, to setup and install a `otlptrace.Exporter` in tracing. (#1963) +- Changes `go.opentelemetry.io/otel/sdk/resource.NewWithAttributes` to require a schema URL. The old function is still available as `resource.NewSchemaless`. This is a breaking change. (#1938) +- Several builtin resource detectors now correctly populate the schema URL. (#1938) +- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlpmetric` that defines a metrics exporter that uses a `otlpmetric.Client` to send data. +- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` implementing a gRPC `otlpmetric.Client` and offers convenience functions, `New` and `NewUnstarted`, to create an `otlpmetric.Exporter`.(#1991) +- Added `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` exporter. (#2005) +- Added `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` exporter. (#2005) +- Added a `TracerProvider()` method to the `"go.opentelemetry.io/otel/trace".Span` interface. This can be used to obtain a `TracerProvider` from a given span that utilizes the same trace processing pipeline. (#2009) + +### Changed + +- Make `NewSplitDriver` from `go.opentelemetry.io/otel/exporters/otlp` take variadic arguments instead of a `SplitConfig` item. + `NewSplitDriver` now automatically implements an internal `noopDriver` for `SplitConfig` fields that are not initialized. (#1798) +- `resource.New()` now creates a Resource without builtin detectors. Previous behavior is now achieved by using `WithBuiltinDetectors` Option. (#1810) +- Move the `Event` type from the `go.opentelemetry.io/otel` package to the `go.opentelemetry.io/otel/sdk/trace` package. (#1846) +- CI builds validate against last two versions of Go, dropping 1.14 and adding 1.16. (#1865) +- BatchSpanProcessor now report export failures when calling `ForceFlush()` method. (#1860) +- `Set.Encoded(Encoder)` no longer caches the result of an encoding. (#1855) +- Renamed `CloudZoneKey` to `CloudAvailabilityZoneKey` in Resource semantic conventions according to spec. (#1871) +- The `StatusCode` and `StatusMessage` methods of the `ReadOnlySpan` interface and the `Span` produced by the `go.opentelemetry.io/otel/sdk/trace` package have been replaced with a single `Status` method. + This method returns the status of a span using the new `Status` type. (#1874) +- Updated `ExportSpans` method of the`SpanExporter` interface type to accept `ReadOnlySpan`s instead of the removed `SpanSnapshot`. + This brings the export interface into compliance with the specification in that it now accepts an explicitly immutable type instead of just an implied one. (#1873) +- Unembed `SpanContext` in `Link`. (#1877) +- Generate Semantic conventions from the specification YAML. (#1891) +- Spans created by the global `Tracer` obtained from `go.opentelemetry.io/otel`, prior to a functioning `TracerProvider` being set, now propagate the span context from their parent if one exists. (#1901) +- The `"go.opentelemetry.io/otel".Tracer` function now accepts tracer options. (#1902) +- Move the `go.opentelemetry.io/otel/unit` package to `go.opentelemetry.io/otel/metric/unit`.

(#1921) +- Changed `go.opentelemetry.io/otel/metric.MeterConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#1921) +- Refactored option types according to the contribution style guide. (#1882) +- Move the `go.opentelemetry.io/otel/trace.TraceStateFromKeyValues` function to the `go.opentelemetry.io/otel/oteltest` package. + This function is preserved for testing purposes where it may be useful to create a `TraceState` from `attribute.KeyValue`s, but it is not intended for production use. + The new `ParseTraceState` function should be used to create a `TraceState`. (#1931) +- Updated `MarshalJSON` method of the `go.opentelemetry.io/otel/trace.TraceState` type to marshal the type into the string representation of the `TraceState`. (#1931) +- The `TraceState.Delete` method from the `go.opentelemetry.io/otel/trace` package no longer returns an error in addition to a `TraceState`. (#1931) +- Updated `Get` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a `string` instead of an `attribute.Key` type. (#1931) +- Updated `Insert` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a pair of `string`s instead of an `attribute.KeyValue` type. (#1931) +- Updated `Delete` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a `string` instead of an `attribute.Key` type. (#1931) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/stdout` package. (#1985) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/metric/prometheus` package. (#1985) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/trace/jaeger` package. (#1985) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/trace/zipkin` package. (#1985) +- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/otlp` package. (#1985) +- Renamed `NewUnstartedExporter` to `NewUnstarted` in the `go.opentelemetry.io/otel/exporters/otlp` package. (#1985) +- The `go.opentelemetry.io/otel/semconv` package has been moved to `go.opentelemetry.io/otel/semconv/v1.4.0` to allow for multiple [telemetry schema](https://github.com/open-telemetry/oteps/blob/main/text/0152-telemetry-schemas.md) versions to be used concurrently. (#1987) +- Metrics test helpers in `go.opentelemetry.io/otel/oteltest` have been moved to `go.opentelemetry.io/otel/metric/metrictest`. (#1988) + +### Deprecated + +- The `go.opentelemetry.io/otel/exporters/metric/prometheus` is deprecated, use `go.opentelemetry.io/otel/exporters/prometheus` instead. (#1993) +- The `go.opentelemetry.io/otel/exporters/trace/jaeger` is deprecated, use `go.opentelemetry.io/otel/exporters/jaeger` instead. (#1993) +- The `go.opentelemetry.io/otel/exporters/trace/zipkin` is deprecated, use `go.opentelemetry.io/otel/exporters/zipkin` instead. (#1993) + +### Removed + +- Removed `resource.WithoutBuiltin()`. Use `resource.New()`. (#1810) +- Unexported types `resource.FromEnv`, `resource.Host`, and `resource.TelemetrySDK`, Use the corresponding `With*()` to use individually. (#1810) +- Removed the `Tracer` and `IsRecording` method from the `ReadOnlySpan` in the `go.opentelemetry.io/otel/sdk/trace`. + The `Tracer` method is not a required to be included in this interface and given the mutable nature of the tracer that is associated with a span, this method is not appropriate. + The `IsRecording` method returns if the span is recording or not. + A read-only span value does not need to know if updates to it will be recorded or not. + By definition, it cannot be updated so there is no point in communicating if an update is recorded. (#1873) +- Removed the `SpanSnapshot` type from the `go.opentelemetry.io/otel/sdk/trace` package. + The use of this type has been replaced with the use of the explicitly immutable `ReadOnlySpan` type. + When a concrete representation of a read-only span is needed for testing, the newly added `SpanStub` in the `go.opentelemetry.io/otel/sdk/trace/tracetest` package should be used. (#1873) +- Removed the `Tracer` method from the `Span` interface in the `go.opentelemetry.io/otel/trace` package. + Using the same tracer that created a span introduces the error where an instrumentation library's `Tracer` is used by other code instead of their own. + The `"go.opentelemetry.io/otel".Tracer` function or a `TracerProvider` should be used to acquire a library specific `Tracer` instead. (#1900) + - The `TracerProvider()` method on the `Span` interface may also be used to obtain a `TracerProvider` using the same trace processing pipeline. (#2009) +- The `http.url` attribute generated by `HTTPClientAttributesFromHTTPRequest` will no longer include username or password information. (#1919) +- Removed `IsEmpty` method of the `TraceState` type in the `go.opentelemetry.io/otel/trace` package in favor of using the added `TraceState.Len` method. (#1931) +- Removed `Set`, `Value`, `ContextWithValue`, `ContextWithoutValue`, and `ContextWithEmpty` functions in the `go.opentelemetry.io/otel/baggage` package. + Handling of baggage is now done using the added `Baggage` type and related context functions (`ContextWithBaggage`, `ContextWithoutBaggage`, and `FromContext`) in that package. (#1967) +- The `InstallNewPipeline` and `NewExportPipeline` creation functions in all the exporters (prometheus, otlp, stdout, jaeger, and zipkin) have been removed. + These functions were deemed premature attempts to provide convenience that did not achieve this aim. (#1985) +- The `go.opentelemetry.io/otel/exporters/otlp` exporter has been removed. Use `go.opentelemetry.io/otel/exporters/otlp/otlptrace` instead. (#1990) +- The `go.opentelemetry.io/otel/exporters/stdout` exporter has been removed. Use `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` or `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` instead. (#2005) + +### Fixed + +- Only report errors from the `"go.opentelemetry.io/otel/sdk/resource".Environment` function when they are not `nil`. (#1850, #1851) +- The `Shutdown` method of the simple `SpanProcessor` in the `go.opentelemetry.io/otel/sdk/trace` package now honors the context deadline or cancellation. (#1616, #1856) +- BatchSpanProcessor now drops span batches that failed to be exported. (#1860) +- Use `http://localhost:14268/api/traces` as default Jaeger collector endpoint instead of `http://localhost:14250`. (#1898) +- Allow trailing and leading whitespace in the parsing of a `tracestate` header. (#1931) +- Add logic to determine if the channel is closed to fix Jaeger exporter test panic with close closed channel. (#1870, #1973) +- Avoid transport security when OTLP endpoint is a Unix socket. (#2001) + +### Security + +## [0.20.0] - 2021-04-23 + +### Added + +- The OTLP exporter now has two new convenience functions, `NewExportPipeline` and `InstallNewPipeline`, setup and install the exporter in tracing and metrics pipelines. (#1373) +- Adds semantic conventions for exceptions. (#1492) +- Added Jaeger Environment variables: `OTEL_EXPORTER_JAEGER_AGENT_HOST`, `OTEL_EXPORTER_JAEGER_AGENT_PORT` + These environment variables can be used to override Jaeger agent hostname and port (#1752) +- Option `ExportTimeout` was added to batch span processor. (#1755) +- `trace.TraceFlags` is now a defined type over `byte` and `WithSampled(bool) TraceFlags` and `IsSampled() bool` methods have been added to it. (#1770) +- The `Event` and `Link` struct types from the `go.opentelemetry.io/otel` package now include a `DroppedAttributeCount` field to record the number of attributes that were not recorded due to configured limits being reached. (#1771) +- The Jaeger exporter now reports dropped attributes for a Span event in the exported log. (#1771) +- Adds test to check BatchSpanProcessor ignores `OnEnd` and `ForceFlush` post `Shutdown`. (#1772) +- Extract resource attributes from the `OTEL_RESOURCE_ATTRIBUTES` environment variable and merge them with the `resource.Default` resource as well as resources provided to the `TracerProvider` and metric `Controller`. (#1785) +- Added `WithOSType` resource configuration option to set OS (Operating System) type resource attribute (`os.type`). (#1788) +- Added `WithProcess*` resource configuration options to set Process resource attributes. (#1788) + - `process.pid` + - `process.executable.name` + - `process.executable.path` + - `process.command_args` + - `process.owner` + - `process.runtime.name` + - `process.runtime.version` + - `process.runtime.description` +- Adds `k8s.node.name` and `k8s.node.uid` attribute keys to the `semconv` package. (#1789) +- Added support for configuring OTLP/HTTP and OTLP/gRPC Endpoints, TLS Certificates, Headers, Compression and Timeout via Environment Variables. (#1758, #1769 and #1811) + - `OTEL_EXPORTER_OTLP_ENDPOINT` + - `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT` + - `OTEL_EXPORTER_OTLP_METRICS_ENDPOINT` + - `OTEL_EXPORTER_OTLP_HEADERS` + - `OTEL_EXPORTER_OTLP_TRACES_HEADERS` + - `OTEL_EXPORTER_OTLP_METRICS_HEADERS` + - `OTEL_EXPORTER_OTLP_COMPRESSION` + - `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION` + - `OTEL_EXPORTER_OTLP_METRICS_COMPRESSION` + - `OTEL_EXPORTER_OTLP_TIMEOUT` + - `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT` + - `OTEL_EXPORTER_OTLP_METRICS_TIMEOUT` + - `OTEL_EXPORTER_OTLP_CERTIFICATE` + - `OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE` + - `OTEL_EXPORTER_OTLP_METRICS_CERTIFICATE` +- Adds `otlpgrpc.WithTimeout` option for configuring timeout to the otlp/gRPC exporter. (#1821) +- Adds `jaeger.WithMaxPacketSize` option for configuring maximum UDP packet size used when connecting to the Jaeger agent. (#1853) + +### Fixed + +- The `Span.IsRecording` implementation from `go.opentelemetry.io/otel/sdk/trace` always returns false when not being sampled. (#1750) +- The Jaeger exporter now correctly sets tags for the Span status code and message. + This means it uses the correct tag keys (`"otel.status_code"`, `"otel.status_description"`) and does not set the status message as a tag unless it is set on the span. (#1761) +- The Jaeger exporter now correctly records Span event's names using the `"event"` key for a tag. + Additionally, this tag is overridden, as specified in the OTel specification, if the event contains an attribute with that key. (#1768) +- Zipkin Exporter: Ensure mapping between OTel and Zipkin span data complies with the specification. (#1688) +- Fixed typo for default service name in Jaeger Exporter. (#1797) +- Fix flaky OTLP for the reconnnection of the client connection. (#1527, #1814) +- Fix Jaeger exporter dropping of span batches that exceed the UDP packet size limit. + Instead, the exporter now splits the batch into smaller sendable batches. (#1828) + +### Changed + +- Span `RecordError` now records an `exception` event to comply with the semantic convention specification. (#1492) +- Jaeger exporter was updated to use thrift v0.14.1. (#1712) +- Migrate from using internally built and maintained version of the OTLP to the one hosted at `go.opentelemetry.io/proto/otlp`. (#1713) +- Migrate from using `github.com/gogo/protobuf` to `google.golang.org/protobuf` to match `go.opentelemetry.io/proto/otlp`. (#1713) +- The storage of a local or remote Span in a `context.Context` using its SpanContext is unified to store just the current Span. + The Span's SpanContext can now self-identify as being remote or not. + This means that `"go.opentelemetry.io/otel/trace".ContextWithRemoteSpanContext` will now overwrite any existing current Span, not just existing remote Spans, and make it the current Span in a `context.Context`. (#1731) +- Improve OTLP/gRPC exporter connection errors. (#1737) +- Information about a parent span context in a `"go.opentelemetry.io/otel/export/trace".SpanSnapshot` is unified in a new `Parent` field. + The existing `ParentSpanID` and `HasRemoteParent` fields are removed in favor of this. (#1748) +- The `ParentContext` field of the `"go.opentelemetry.io/otel/sdk/trace".SamplingParameters` is updated to hold a `context.Context` containing the parent span. + This changes it to make `SamplingParameters` conform with the OpenTelemetry specification. (#1749) +- Updated Jaeger Environment Variables: `JAEGER_ENDPOINT`, `JAEGER_USER`, `JAEGER_PASSWORD` + to `OTEL_EXPORTER_JAEGER_ENDPOINT`, `OTEL_EXPORTER_JAEGER_USER`, `OTEL_EXPORTER_JAEGER_PASSWORD` in compliance with OTel specification. (#1752) +- Modify `BatchSpanProcessor.ForceFlush` to abort after timeout/cancellation. (#1757) +- The `DroppedAttributeCount` field of the `Span` in the `go.opentelemetry.io/otel` package now only represents the number of attributes dropped for the span itself. + It no longer is a conglomerate of itself, events, and link attributes that have been dropped. (#1771) +- Make `ExportSpans` in Jaeger Exporter honor context deadline. (#1773) +- Modify Zipkin Exporter default service name, use default resource's serviceName instead of empty. (#1777) +- The `go.opentelemetry.io/otel/sdk/export/trace` package is merged into the `go.opentelemetry.io/otel/sdk/trace` package. (#1778) +- The prometheus.InstallNewPipeline example is moved from comment to example test (#1796) +- The convenience functions for the stdout exporter have been updated to return the `TracerProvider` implementation and enable the shutdown of the exporter. (#1800) +- Replace the flush function returned from the Jaeger exporter's convenience creation functions (`InstallNewPipeline` and `NewExportPipeline`) with the `TracerProvider` implementation they create. + This enables the caller to shutdown and flush using the related `TracerProvider` methods. (#1822) +- Updated the Jaeger exporter to have a default endpoint, `http://localhost:14250`, for the collector. (#1824) +- Changed the function `WithCollectorEndpoint` in the Jaeger exporter to no longer accept an endpoint as an argument. + The endpoint can be passed with the `CollectorEndpointOption` using the `WithEndpoint` function or by setting the `OTEL_EXPORTER_JAEGER_ENDPOINT` environment variable value appropriately. (#1824) +- The Jaeger exporter no longer batches exported spans itself, instead it relies on the SDK's `BatchSpanProcessor` for this functionality. (#1830) +- The Jaeger exporter creation functions (`NewRawExporter`, `NewExportPipeline`, and `InstallNewPipeline`) no longer accept the removed `Option` type as a variadic argument. (#1830) + +### Removed + +- Removed Jaeger Environment variables: `JAEGER_SERVICE_NAME`, `JAEGER_DISABLED`, `JAEGER_TAGS` + These environment variables will no longer be used to override values of the Jaeger exporter (#1752) +- No longer set the links for a `Span` in `go.opentelemetry.io/otel/sdk/trace` that is configured to be a new root. + This is unspecified behavior that the OpenTelemetry community plans to standardize in the future. + To prevent backwards incompatible changes when it is specified, these links are removed. (#1726) +- Setting error status while recording error with Span from oteltest package. (#1729) +- The concept of a remote and local Span stored in a context is unified to just the current Span. + Because of this `"go.opentelemetry.io/otel/trace".RemoteSpanContextFromContext` is removed as it is no longer needed. + Instead, `"go.opentelemetry.io/otel/trace".SpanContextFromContext` can be used to return the current Span. + If needed, that Span's `SpanContext.IsRemote()` can then be used to determine if it is remote or not. (#1731) +- The `HasRemoteParent` field of the `"go.opentelemetry.io/otel/sdk/trace".SamplingParameters` is removed. + This field is redundant to the information returned from the `Remote` method of the `SpanContext` held in the `ParentContext` field. (#1749) +- The `trace.FlagsDebug` and `trace.FlagsDeferred` constants have been removed and will be localized to the B3 propagator. (#1770) +- Remove `Process` configuration, `WithProcessFromEnv` and `ProcessFromEnv`, and type from the Jaeger exporter package. + The information that could be configured in the `Process` struct should be configured in a `Resource` instead. (#1776, #1804) +- Remove the `WithDisabled` option from the Jaeger exporter. + To disable the exporter unregister it from the `TracerProvider` or use a no-operation `TracerProvider`. (#1806) +- Removed the functions `CollectorEndpointFromEnv` and `WithCollectorEndpointOptionFromEnv` from the Jaeger exporter. + These functions for retrieving specific environment variable values are redundant of other internal functions and + are not intended for end user use. (#1824) +- Removed the Jaeger exporter `WithSDKOptions` `Option`. + This option was used to set SDK options for the exporter creation convenience functions. + These functions are provided as a way to easily setup or install the exporter with what are deemed reasonable SDK settings for common use cases. + If the SDK needs to be configured differently, the `NewRawExporter` function and direct setup of the SDK with the desired settings should be used. (#1825) +- The `WithBufferMaxCount` and `WithBatchMaxCount` `Option`s from the Jaeger exporter are removed. + The exporter no longer batches exports, instead relying on the SDK's `BatchSpanProcessor` for this functionality. (#1830) +- The Jaeger exporter `Option` type is removed. + The type is no longer used by the exporter to configure anything. + All the previous configurations these options provided were duplicates of SDK configuration. + They have been removed in favor of using the SDK configuration and focuses the exporter configuration to be only about the endpoints it will send telemetry to. (#1830) + +## [0.19.0] - 2021-03-18 + +### Added + +- Added `Marshaler` config option to `otlphttp` to enable otlp over json or protobufs. (#1586) +- A `ForceFlush` method to the `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` to flush all registered `SpanProcessor`s. (#1608) +- Added `WithSampler` and `WithSpanLimits` to tracer provider. (#1633, #1702) +- `"go.opentelemetry.io/otel/trace".SpanContext` now has a `remote` property, and `IsRemote()` predicate, that is true when the `SpanContext` has been extracted from remote context data. (#1701) +- A `Valid` method to the `"go.opentelemetry.io/otel/attribute".KeyValue` type. (#1703) + +### Changed + +- `trace.SpanContext` is now immutable and has no exported fields. (#1573) + - `trace.NewSpanContext()` can be used in conjunction with the `trace.SpanContextConfig` struct to initialize a new `SpanContext` where all values are known. +- Update the `ForceFlush` method signature to the `"go.opentelemetry.io/otel/sdk/trace".SpanProcessor` to accept a `context.Context` and return an error. (#1608) +- Update the `Shutdown` method to the `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` return an error on shutdown failure. (#1608) +- The SimpleSpanProcessor will now shut down the enclosed `SpanExporter` and gracefully ignore subsequent calls to `OnEnd` after `Shutdown` is called. (#1612) +- `"go.opentelemetry.io/sdk/metric/controller.basic".WithPusher` is replaced with `WithExporter` to provide consistent naming across project. (#1656) +- Added non-empty string check for trace `Attribute` keys. (#1659) +- Add `description` to SpanStatus only when `StatusCode` is set to error. (#1662) +- Jaeger exporter falls back to `resource.Default`'s `service.name` if the exported Span does not have one. (#1673) +- Jaeger exporter populates Jaeger's Span Process from Resource. (#1673) +- Renamed the `LabelSet` method of `"go.opentelemetry.io/otel/sdk/resource".Resource` to `Set`. (#1692) +- Changed `WithSDK` to `WithSDKOptions` to accept variadic arguments of `TracerProviderOption` type in `go.opentelemetry.io/otel/exporters/trace/jaeger` package. (#1693) +- Changed `WithSDK` to `WithSDKOptions` to accept variadic arguments of `TracerProviderOption` type in `go.opentelemetry.io/otel/exporters/trace/zipkin` package. (#1693) + +### Removed + +- Removed `serviceName` parameter from Zipkin exporter and uses resource instead. (#1549) +- Removed `WithConfig` from tracer provider to avoid overriding configuration. (#1633) +- Removed the exported `SimpleSpanProcessor` and `BatchSpanProcessor` structs. + These are now returned as a SpanProcessor interface from their respective constructors. (#1638) +- Removed `WithRecord()` from `trace.SpanOption` when creating a span. (#1660) +- Removed setting status to `Error` while recording an error as a span event in `RecordError`. (#1663) +- Removed `jaeger.WithProcess` configuration option. (#1673) +- Removed `ApplyConfig` method from `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` and the now unneeded `Config` struct. (#1693) + +### Fixed + +- Jaeger Exporter: Ensure mapping between OTEL and Jaeger span data complies with the specification. (#1626) +- `SamplingResult.TraceState` is correctly propagated to a newly created span's `SpanContext`. (#1655) +- The `otel-collector` example now correctly flushes metric events prior to shutting down the exporter. (#1678) +- Do not set span status message in `SpanStatusFromHTTPStatusCode` if it can be inferred from `http.status_code`. (#1681) +- Synchronization issues in global trace delegate implementation. (#1686) +- Reduced excess memory usage by global `TracerProvider`. (#1687) + +## [0.18.0] - 2021-03-03 + +### Added + +- Added `resource.Default()` for use with meter and tracer providers.

(#1027) +- The `WithSpan` method of the `Tracer` interface. + The functionality this method provided was limited compared to what a user can provide themselves. + It was removed with the understanding that if there is sufficient user need it can be added back based on actual user usage. (#1043) +- The `RegisterSpanProcessor` and `UnregisterSpanProcessor` functions. + These were holdovers from an approach prior to the TracerProvider design. They were not used anymore. (#1077) +- The `oterror` package. (#1026) +- The `othttp` and `httptrace` instrumentations were moved to `go.opentelemetry.io/contrib`.

(#979) +- Rename `go.opentelemetry.io/otel/sdk/metric/aggregator/test` package to `go.opentelemetry.io/otel/sdk/metric/aggregator/aggregatortest`. (#980) +- Make the SDK into its own Go module called `go.opentelemetry.io/otel/sdk`. (#985) +- Changed the default trace `Sampler` from `AlwaysOn` to `ParentOrElse(AlwaysOn)`. (#989) + +### Removed + +- The `IndexedAttribute` function from the `go.opentelemetry.io/otel/api/label` package was removed in favor of `IndexedLabel` which it was synonymous with. (#970) + +### Fixed + +- Bump github.com/golangci/golangci-lint from 1.28.3 to 1.29.0 in /tools. (#953) +- Bump github.com/google/go-cmp from 0.5.0 to 0.5.1.

(#905) +- Add semantic conventions for operating system process resource attribute keys. (#919) +- The Jaeger exporter now has a `WithBatchMaxCount` option to specify the maximum number of spans sent in a batch. (#931) + +### Changed + +- Update `CONTRIBUTING.md` to ask for updates to `CHANGELOG.md` with each pull request. (#879) +- Use lowercase header names for B3 Multiple Headers. (#881) +- The B3 propagator `SingleHeader` field has been replaced with `InjectEncoding`. + This new field can be set to combinations of the `B3Encoding` bitmasks and will inject trace information in these encodings. + If no encoding is set, the propagator will default to `MultipleHeader` encoding. (#882) +- The B3 propagator now extracts from either HTTP encoding of B3 (Single Header or Multiple Header) based on what is contained in the header. + Preference is given to Single Header encoding with Multiple Header being the fallback if Single Header is not found or is invalid. + This behavior change is made to dynamically support all correctly encoded traces received instead of having to guess the expected encoding prior to receiving.

(#882) + +### Fixed + +- The B3 Single Header name is now correctly `b3` instead of the previous `X-B3`. (#881) +- The B3 propagator now correctly supports sampling only values (`b3: 0`, `b3: 1`, or `b3: d`) for a Single B3 Header. (#882) +- The B3 propagator now propagates the debug flag. + This removes the behavior of changing the debug flag into a set sampling bit. + Instead, this now follow the B3 specification and omits the `X-B3-Sampling` header. (#882) +- The B3 propagator now tracks "unset" sampling state (meaning "defer the decision") and does not set the `X-B3-Sampling` header when injecting.

(#915) +- The `grpctrace` instrumentation uses a span name conforming to the OpenTelemetry semantic conventions (does not contain a leading slash (`/`)). (#922) +- The `grpctrace` instrumentation includes an `rpc.method` attribute now set to the gRPC method name. (#900, #922) +- The `grpctrace` instrumentation `rpc.service` attribute now contains the package name if one exists. + This is in accordance with OpenTelemetry semantic conventions. (#922) +- Correlation Context extractor will no longer insert an empty map into the returned context when no valid values are extracted. (#923) +- Bump google.golang.org/api from 0.28.0 to 0.29.0 in /exporters/trace/jaeger. (#925) +- Bump github.com/itchyny/gojq from 0.10.4 to 0.11.0 in /tools.

(#811) (#805) (#802) +- The OTLP exporter includes the instrumentation version in telemetry it exports. (#811) +- Environment variables for Jaeger exporter are supported. (#796) +- New `aggregation.Kind` in the export metric API. (#808) +- New example that uses OTLP and the collector. (#790) +- Handle errors in the span `SetName` during span initialization. (#791) +- Default service config to enable retries for retry-able failed requests in the OTLP exporter and an option to override this default. (#777) +- New `go.opentelemetry.io/otel/api/oterror` package to uniformly support error handling and definitions for the project. (#778) +- New `global` default implementation of the `go.opentelemetry.io/otel/api/oterror.Handler` interface to be used to handle errors prior to an user defined `Handler`. + There is also functionality for the user to register their `Handler` as well as a convenience function `Handle` to handle an error with this global `Handler`(#778) +- Options to specify propagators for httptrace and grpctrace instrumentation.

(#840) +- The `Aggregator.Checkpoint` API is renamed to `SynchronizedCopy` and adds an argument, a different `Aggregator` into which the copy is stored. (#812) +- The `export.Aggregator` contract is that `Update()` and `SynchronizedCopy()` are synchronized with each other. + All the aggregation interfaces (`Sum`, `LastValue`, ...) are not meant to be synchronized, as the caller is expected to synchronize aggregators at a higher level after the `Accumulator`. + Some of the `Aggregators` used unnecessary locking and that has been cleaned up. (#812) +- Use of `metric.Number` was replaced by `int64` now that we use `sync.Mutex` in the `MinMaxSumCount` and `Histogram` `Aggregators`. (#812) +- Replace `AlwaysParentSample` with `ParentSample(fallback)` to match the OpenTelemetry v0.5.0 specification.

(#558) +- The metric `Descriptor` is now included at the API instead of the SDK. (#560) +- Replace `Ordered` with an iterator in `export.Labels`. (#567) + +### Removed + +- The vendor specific Stackdriver. It is now hosted on 3rd party vendor infrastructure. (#452) +- The `Unregister` method for metric observers as it is not in the OpenTelemetry specification. (#560) +- `GetDescriptor` from the metric SDK. (#575) +- The `Gauge` instrument from the metric API. (#537) + +### Fixed + +- Make histogram aggregator checkpoint consistent. (#438) +- Update README with import instructions and how to build and test. (#505) +- The default label encoding was updated to be unique. (#508) +- Use `NewRoot` in the othttp plugin for public endpoints. (#513) +- Fix data race in `BatchedSpanProcessor`. (#518) +- Skip test-386 for Mac OS 10.15.x (Catalina and upwards). #521 +- Use a variable-size array to represent ordered labels in maps. (#523) +- Update the OTLP protobuf and update changed import path. (#532) +- Use `StateLocker` implementation in `MinMaxSumCount`. (#546) +- Eliminate goroutine leak in histogram stress test. (#547) +- Update OTLP exporter with latest protobuf. (#550) +- Add filters to the othttp plugin. (#556) +- Provide an implementation of the `Header*` filters that do not depend on Go 1.14. (#565) +- Encode labels once during checkpoint. + The checkpoint function is executed in a single thread so we can do the encoding lazily before passing the encoded version of labels to the exporter. + This is a cheap and quick way to avoid encoding the labels on every collection interval. (#572) +- Run coverage over all packages in `COVERAGE_MOD_DIR`. (#573) + +## [0.2.3] - 2020-03-04 + +### Added + +- `RecordError` method on `Span`s in the trace API to Simplify adding error events to spans. (#473) +- Configurable push frequency for exporters setup pipeline. (#504) + +### Changed + +- Rename the `exporter` directory to `exporters`. + The `go.opentelemetry.io/otel/exporter/trace/jaeger` package was mistakenly released with a `v1.0.0` tag instead of `v0.1.0`. + This resulted in all subsequent releases not becoming the default latest. + A consequence of this was that all `go get`s pulled in the incompatible `v0.1.0` release of that package when pulling in more recent packages from other otel packages. + Renaming the `exporter` directory to `exporters` fixes this issue by renaming the package and therefore clearing any existing dependency tags. + Consequentially, this action also renames *all* exporter packages. (#502) + +### Removed + +- The `CorrelationContextHeader` constant in the `correlation` package is no longer exported. (#503) + +## [0.2.2] - 2020-02-27 + +### Added + +- `HTTPSupplier` interface in the propagation API to specify methods to retrieve and store a single value for a key to be associated with a carrier.

(#467) +- `ExtractHTTP` and `InjectHTTP` functions to apply configured HTTP extractors and injectors to a passed context. (#467) +- Histogram aggregator. (#433) +- `DefaultPropagator` function and have it return `trace.TraceContext` as the default context propagator. (#456) +- `AlwaysParentSample` sampler to the trace API. (#455) +- `WithNewRoot` option function to the trace API to specify the created span should be considered a root span. (#451) + +### Changed + +- Renamed `WithMap` to `ContextWithMap` in the correlation package. (#481) +- Renamed `FromContext` to `MapFromContext` in the correlation package. (#481) +- Move correlation context propagation to correlation package. (#479) +- Do not default to putting remote span context into links. (#480) +- `Tracer.WithSpan` updated to accept `StartOptions`. (#472) +- Renamed `MetricKind` to `Kind` to not stutter in the type usage. (#432) +- Renamed the `export` package to `metric` to match directory structure. (#432) +- Rename the `api/distributedcontext` package to `api/correlation`. (#444) +- Rename the `api/propagators` package to `api/propagation`. (#444) +- Move the propagators from the `propagators` package into the `trace` API package. (#444) +- Update `Float64Gauge`, `Int64Gauge`, `Float64Counter`, `Int64Counter`, `Float64Measure`, and `Int64Measure` metric methods to use value receivers instead of pointers. (#462) +- Moved all dependencies of tools package to a tools directory. (#466) + +### Removed + +- Binary propagators. (#467) +- NOOP propagator. (#467) + +### Fixed + +- Upgraded `github.com/golangci/golangci-lint` from `v1.21.0` to `v1.23.6` in `tools/`. (#492) +- Fix a possible nil-dereference crash (#478) +- Correct comments for `InstallNewPipeline` in the stdout exporter. (#483) +- Correct comments for `InstallNewPipeline` in the dogstatsd exporter. (#484) +- Correct comments for `InstallNewPipeline` in the prometheus exporter. (#482) +- Initialize `onError` based on `Config` in prometheus exporter. (#486) +- Correct module name in prometheus exporter README. (#475) +- Removed tracer name prefix from span names. (#430) +- Fix `aggregator_test.go` import package comment. (#431) +- Improved detail in stdout exporter. (#436) +- Fix a dependency issue (generate target should depend on stringer, not lint target) in Makefile. (#442) +- Reorders the Makefile targets within `precommit` target so we generate files and build the code before doing linting, so we can get much nicer errors about syntax errors from the compiler. (#442) +- Reword function documentation in gRPC plugin. (#446) +- Send the `span.kind` tag to Jaeger from the jaeger exporter. (#441) +- Fix `metadataSupplier` in the jaeger exporter to overwrite the header if existing instead of appending to it. (#441) +- Upgraded to Go 1.13 in CI. (#465) +- Correct opentelemetry.io URL in trace SDK documentation. (#464) +- Refactored reference counting logic in SDK determination of stale records. (#468) +- Add call to `runtime.Gosched` in instrument `acquireHandle` logic to not block the collector. (#469) + +## [0.2.1.1] - 2020-01-13 + +### Fixed + +- Use stateful batcher on Prometheus exporter fixing regression introduced in #395. (#428) + +## [0.2.1] - 2020-01-08 + +### Added + +- Global meter forwarding implementation. + This enables deferred initialization for metric instruments registered before the first Meter SDK is installed. (#392) +- Global trace forwarding implementation. + This enables deferred initialization for tracers registered before the first Trace SDK is installed. (#406) +- Standardize export pipeline creation in all exporters. (#395) +- A testing, organization, and comments for 64-bit field alignment. (#418) +- Script to tag all modules in the project. (#414) + +### Changed + +- Renamed `propagation` package to `propagators`. (#362) +- Renamed `B3Propagator` propagator to `B3`. (#362) +- Renamed `TextFormatPropagator` propagator to `TextFormat`.

(#400) +- Renamed the `File` option in the stdout exporter to `Writer`. (#404) +- Renamed all `Options` to `Config` for all metric exports where this wasn't already the case. + +### Fixed + +- Aggregator import path corrected. (#421) +- Correct links in README.

(#336) +- Trace benchmark now tests both `AlwaysSample` and `NeverSample`. + Previously it was testing `AlwaysSample` twice. (#325) +- Trace benchmark now uses a `[]byte` for `TraceID` to fix failing test. (#325) +- Added a trace benchmark to test variadic functions in `setAttribute` vs `setAttributes` (#325) +- The `defaultkeys` batcher was only using the encoded label set as its map key while building a checkpoint. + This allowed distinct label sets through, but any metrics sharing a label set could be overwritten or merged incorrectly. + This was corrected. (#333) + +## [0.1.2] - 2019-11-18 + +### Fixed + +- Optimized the `simplelru` map for attributes to reduce the number of allocations. (#328) +- Removed unnecessary unslicing of parameters that are already a slice.

to opentelemetry-go + +The Go special interest group (SIG) meets regularly. See the +OpenTelemetry +[community](https://github.com/open-telemetry/community#golang-sdk) +repo for information on this and other language SIGs. + +See the [public meeting +notes](https://docs.google.com/document/d/1E5e7Ld0NuU1iVvf-42tOBpu2VBBLYnh73GJuITGJTTU/edit) +for a summary description of past meetings. To request edit access, +join the meeting or get in touch on +[Slack](https://cloud-native.slack.com/archives/C01NPAXACKT). + +## Development + +You can view and edit the source code by cloning this repository: + +```sh +git clone https://github.com/open-telemetry/opentelemetry-go.git +``` + +Run `make test` to run the tests instead of `go test`. + +There are some generated files checked into the repo. To make sure +that the generated files are up-to-date, run `make` (or `make +precommit` - the `precommit` target is the default). + +The `precommit` target also fixes the formatting of the code and +checks the status of the go module files. + +Additionally, there is a `codespell` target that checks for common +typos in the code. It is not run by default, but you can run it +manually with `make codespell`. It will set up a virtual environment +in `venv` and install `codespell` there. + +If after running `make precommit` the output of `git status` contains +`nothing to commit, working tree clean` then it means that everything +is up-to-date and properly formatted. + +## Pull Requests + +### How to Send Pull Requests + +Everyone is welcome to contribute code to `opentelemetry-go` via +GitHub pull requests (PRs). + +To create a new PR, fork the project in GitHub and clone the upstream +repo: + +```sh +go get -d go.opentelemetry.io/otel +``` + +(This may print some warning about "build constraints exclude all Go +files", just ignore it.) + +This will put the project in `${GOPATH}/src/go.opentelemetry.io/otel`. You +can alternatively use `git` directly with: + +```sh +git clone https://github.com/open-telemetry/opentelemetry-go +``` + +(Note that `git clone` is *not* using the `go.opentelemetry.io/otel` name - +that name is a kind of a redirector to GitHub that `go get` can +understand, but `git` does not.) + +This would put the project in the `opentelemetry-go` directory in +current working directory. + +Enter the newly created directory and add your fork as a new remote: + +```sh +git remote add git@github.com:/opentelemetry-go +``` + +Check out a new branch, make modifications, run linters and tests, update +`CHANGELOG.md`, and push the branch to your fork: + +```sh +git checkout -b +# edit files +# update changelog +make precommit +git add -p +git commit +git push +``` + +Open a pull request against the main `opentelemetry-go` repo. Be sure to add the pull +request ID to the entry you added to `CHANGELOG.md`. + +Avoid rebasing and force-pushing to your branch to facilitate reviewing the pull request. +Rewriting Git history makes it difficult to keep track of iterations during code review. +All pull requests are squashed to a single commit upon merge to `main`. + +### How to Receive Comments + +* If the PR is not ready for review, please put `[WIP]` in the title, + tag it as `work-in-progress`, or mark it as + [`draft`](https://github.blog/2019-02-14-introducing-draft-pull-requests/). +* Make sure CLA is signed and CI is clear. + +### How to Get PRs Merged + +A PR is considered **ready to merge** when: + +* It has received two qualified approvals[^1]. + + This is not enforced through automation, but needs to be validated by the + maintainer merging. + * The qualified approvals need to be from [Approver]s/[Maintainer]s + affiliated with different companies. Two qualified approvals from + [Approver]s or [Maintainer]s affiliated with the same company counts as a + single qualified approval. + * PRs introducing changes that have already been discussed and consensus + reached only need one qualified approval. The discussion and resolution + needs to be linked to the PR. + * Trivial changes[^2] only need one qualified approval. + +* All feedback has been addressed. + * All PR comments and suggestions are resolved. + * All GitHub Pull Request reviews with a status of "Request changes" have + been addressed. Another review by the objecting reviewer with a different + status can be submitted to clear the original review, or the review can be + dismissed by a [Maintainer] when the issues from the original review have + been addressed. + * Any comments or reviews that cannot be resolved between the PR author and + reviewers can be submitted to the community [Approver]s and [Maintainer]s + during the weekly SIG meeting. If consensus is reached among the + [Approver]s and [Maintainer]s during the SIG meeting the objections to the + PR may be dismissed or resolved or the PR closed by a [Maintainer]. + * Any substantive changes to the PR require existing Approval reviews be + cleared unless the approver explicitly states that their approval persists + across changes. This includes changes resulting from other feedback. + [Approver]s and [Maintainer]s can help in clearing reviews and they should + be consulted if there are any questions. + +* The PR branch is up to date with the base branch it is merging into. + * To ensure this does not block the PR, it should be configured to allow + maintainers to update it. + +* It has been open for review for at least one working day. This gives people + reasonable time to review. + * Trivial changes[^2] do not have to wait for one day and may be merged with + a single [Maintainer]'s approval. + +* All required GitHub workflows have succeeded. +* Urgent fix can take exception as long as it has been actively communicated + among [Maintainer]s. + +Any [Maintainer] can merge the PR once the above criteria have been met. + +[^1]: A qualified approval is a GitHub Pull Request review with "Approve" + status from an OpenTelemetry Go [Approver] or [Maintainer]. +[^2]: Trivial changes include: typo corrections, cosmetic non-substantive + changes, documentation corrections or updates, dependency updates, etc. + +## Design Choices + +As with other OpenTelemetry clients, opentelemetry-go follows the +[OpenTelemetry Specification](https://opentelemetry.io/docs/specs/otel). + +It's especially valuable to read through the [library +guidelines](https://opentelemetry.io/docs/specs/otel/library-guidelines). + +### Focus on Capabilities, Not Structure Compliance + +OpenTelemetry is an evolving specification, one where the desires and +use cases are clear, but the method to satisfy those uses cases are +not. + +As such, Contributions should provide functionality and behavior that +conforms to the specification, but the interface and structure is +flexible. + +It is preferable to have contributions follow the idioms of the +language rather than conform to specific API names or argument +patterns in the spec. + +For a deeper discussion, see +[this](https://github.com/open-telemetry/opentelemetry-specification/issues/165). + +## Tests + +Each functionality should be covered by tests. + +Performance-critical functionality should also be covered by benchmarks. + +- Pull requests adding a performance-critical functionality +should have `go test -bench` output in their description. +- Pull requests changing a performance-critical functionality +should have [`benchstat`](https://pkg.go.dev/golang.org/x/perf/cmd/benchstat) +output in their description. + +## Documentation + +Each (non-internal, non-test) package must be documented using +[Go Doc Comments](https://go.dev/doc/comment), +preferably in a `doc.go` file. + +Prefer using [Examples](https://pkg.go.dev/testing#hdr-Examples) +instead of putting code snippets in Go doc comments. +In some cases, you can even create [Testable Examples](https://go.dev/blog/examples). + +You can install and run a "local Go Doc site" in the following way: + + ```sh + go install golang.org/x/pkgsite/cmd/pkgsite@latest + pkgsite + ``` + +[`go.opentelemetry.io/otel/metric`](https://pkg.go.dev/go.opentelemetry.io/otel/metric) +is an example of a very well-documented package. + +### README files + +Each (non-internal, non-test, non-documentation) package must contain a +`README.md` file containing at least a title, and a `pkg.go.dev` badge. + +The README should not be a repetition of Go doc comments. + +You can verify the presence of all README files with the `make verify-readmes` +command. + +## Style Guide + +One of the primary goals of this project is that it is actually used by +developers. With this goal in mind the project strives to build +user-friendly and idiomatic Go code adhering to the Go community's best +practices. + +For a non-comprehensive but foundational overview of these best practices +the [Effective Go](https://golang.org/doc/effective_go.html) documentation +is an excellent starting place. + +As a convenience for developers building this project the `make precommit` +will format, lint, validate, and in some cases fix the changes you plan to +submit. This check will need to pass for your changes to be able to be +merged. + +In addition to idiomatic Go, the project has adopted certain standards for +implementations of common patterns. These standards should be followed as a +default, and if they are not followed documentation needs to be included as +to the reasons why. + +### Configuration + +When creating an instantiation function for a complex `type T struct`, it is +useful to allow variable number of options to be applied. However, the strong +type system of Go restricts the function design options. There are a few ways +to solve this problem, but we have landed on the following design. + +#### `config` + +Configuration should be held in a `struct` named `config`, or prefixed with +specific type name this Configuration applies to if there are multiple +`config` in the package. This type must contain configuration options. + +```go +// config contains configuration options for a thing. +type config struct { + // options ... +} +``` + +In general the `config` type will not need to be used externally to the +package and should be unexported. If, however, it is expected that the user +will likely want to build custom options for the configuration, the `config` +should be exported. Please, include in the documentation for the `config` +how the user can extend the configuration. + +It is important that internal `config` are not shared across package boundaries. +Meaning a `config` from one package should not be directly used by another. The +one exception is the API packages. The configs from the base API, eg. +`go.opentelemetry.io/otel/trace.TracerConfig` and +`go.opentelemetry.io/otel/metric.InstrumentConfig`, are intended to be consumed +by the SDK therefore it is expected that these are exported. + +When a config is exported we want to maintain forward and backward +compatibility, to achieve this no fields should be exported but should +instead be accessed by methods. + +Optionally, it is common to include a `newConfig` function (with the same +naming scheme). This function wraps any defaults setting and looping over +all options to create a configured `config`. + +```go +// newConfig returns an appropriately configured config. +func newConfig(options ...Option) config { + // Set default values for config. + config := config{/* […] */} + for _, option := range options { + config = option.apply(config) + } + // Perform any validation here. + return config +} +``` + +If validation of the `config` options is also performed this can return an +error as well that is expected to be handled by the instantiation function +or propagated to the user. + +Given the design goal of not having the user need to work with the `config`, +the `newConfig` function should also be unexported. + +#### `Option` + +To set the value of the options a `config` contains, a corresponding +`Option` interface type should be used. + +```go +type Option interface { + apply(config) config +} +``` + +Having `apply` unexported makes sure that it will not be used externally. +Moreover, the interface becomes sealed so the user cannot easily implement +the interface on its own. + +The `apply` method should return a modified version of the passed config. +This approach, instead of passing a pointer, is used to prevent the config from being allocated to the heap. + +The name of the interface should be prefixed in the same way the +corresponding `config` is (if at all). + +#### Options + +All user configurable options for a `config` must have a related unexported +implementation of the `Option` interface and an exported configuration +function that wraps this implementation. + +The wrapping function name should be prefixed with `With*` (or in the +special case of a boolean options `Without*`) and should have the following +function signature. + +```go +func With*(…) Option { … } +``` + +##### `bool` Options + +```go +type defaultFalseOption bool + +func (o defaultFalseOption) apply(c config) config { + c.Bool = bool(o) + return c +} + +// WithOption sets a T to have an option included. +func WithOption() Option { + return defaultFalseOption(true) +} +``` + +```go +type defaultTrueOption bool + +func (o defaultTrueOption) apply(c config) config { + c.Bool = bool(o) + return c +} + +// WithoutOption sets a T to have Bool option excluded. +func WithoutOption() Option { + return defaultTrueOption(false) +} +``` + +##### Declared Type Options + +```go +type myTypeOption struct { + MyType MyType +} + +func (o myTypeOption) apply(c config) config { + c.MyType = o.MyType + return c +} + +// WithMyType sets T to have include MyType. +func WithMyType(t MyType) Option { + return myTypeOption{t} +} +``` + +##### Functional Options + +```go +type optionFunc func(config) config + +func (fn optionFunc) apply(c config) config { + return fn(c) +} + +// WithMyType sets t as MyType. +func WithMyType(t MyType) Option { + return optionFunc(func(c config) config { + c.MyType = t + return c + }) +} +``` + +#### Instantiation + +Using this configuration pattern to configure instantiation with a `NewT` +function. + +```go +func NewT(options ...Option) T {…} +``` + +Any required parameters can be declared before the variadic `options`. + +#### Dealing with Overlap + +Sometimes there are multiple complex `struct` that share common +configuration and also have distinct configuration. To avoid repeated +portions of `config`s, a common `config` can be used with the union of +options being handled with the `Option` interface. + +For example. + +```go +// config holds options for all animals. +type config struct { + Weight float64 + Color string + MaxAltitude float64 +} + +// DogOption apply Dog specific options. +type DogOption interface { + applyDog(config) config +} + +// BirdOption apply Bird specific options. +type BirdOption interface { + applyBird(config) config +} + +// Option apply options for all animals. +type Option interface { + BirdOption + DogOption +} + +type weightOption float64 + +func (o weightOption) applyDog(c config) config { + c.Weight = float64(o) + return c +} + +func (o weightOption) applyBird(c config) config { + c.Weight = float64(o) + return c +} + +func WithWeight(w float64) Option { return weightOption(w) } + +type furColorOption string + +func (o furColorOption) applyDog(c config) config { + c.Color = string(o) + return c +} + +func WithFurColor(c string) DogOption { return furColorOption(c) } + +type maxAltitudeOption float64 + +func (o maxAltitudeOption) applyBird(c config) config { + c.MaxAltitude = float64(o) + return c +} + +func WithMaxAltitude(a float64) BirdOption { return maxAltitudeOption(a) } + +func NewDog(name string, o ...DogOption) Dog {…} +func NewBird(name string, o ...BirdOption) Bird {…} +``` + +### Interfaces + +To allow other developers to better comprehend the code, it is important +to ensure it is sufficiently documented. One simple measure that contributes +to this aim is self-documenting by naming method parameters. Therefore, +where appropriate, methods of every exported interface type should have +their parameters appropriately named. + +#### Interface Stability + +All exported stable interfaces that include the following warning in their +documentation are allowed to be extended with additional methods. + +> Warning: methods may be added to this interface in minor releases. + +These interfaces are defined by the OpenTelemetry specification and will be +updated as the specification evolves. + +Otherwise, stable interfaces MUST NOT be modified. + +#### How to Change Specification Interfaces + +When an API change must be made, we will update the SDK with the new method one +release before the API change. This will allow the SDK one version before the +API change to work seamlessly with the new API. + +If an incompatible version of the SDK is used with the new API the application +will fail to compile. + +#### How Not to Change Specification Interfaces + +We have explored using a v2 of the API to change interfaces and found that there +was no way to introduce a v2 and have it work seamlessly with the v1 of the API. +Problems happened with libraries that upgraded to v2 when an application did not, +and would not produce any telemetry. + +More detail of the approaches considered and their limitations can be found in +the [Use a V2 API to evolve interfaces](https://github.com/open-telemetry/opentelemetry-go/issues/3920) +issue. + +#### How to Change Other Interfaces + +If new functionality is needed for an interface that cannot be changed it MUST +be added by including an additional interface. That added interface can be a +simple interface for the specific functionality that you want to add or it can +be a super-set of the original interface. For example, if you wanted to a +`Close` method to the `Exporter` interface: + +```go +type Exporter interface { + Export() +} +``` + +A new interface, `Closer`, can be added: + +```go +type Closer interface { + Close() +} +``` + +Code that is passed the `Exporter` interface can now check to see if the passed +value also satisfies the new interface. E.g. + +```go +func caller(e Exporter) { + /* ... */ + if c, ok := e.(Closer); ok { + c.Close() + } + /* ... */ +} +``` + +Alternatively, a new type that is the super-set of an `Exporter` can be created. + +```go +type ClosingExporter struct { + Exporter + Close() +} +``` + +This new type can be used similar to the simple interface above in that a +passed `Exporter` type can be asserted to satisfy the `ClosingExporter` type +and the `Close` method called. + +This super-set approach can be useful if there is explicit behavior that needs +to be coupled with the original type and passed as a unified type to a new +function, but, because of this coupling, it also limits the applicability of +the added functionality. If there exist other interfaces where this +functionality should be added, each one will need their own super-set +interfaces and will duplicate the pattern. For this reason, the simple targeted +interface that defines the specific functionality should be preferred. + +See also: +[Keeping Your Modules Compatible: Working with interfaces](https://go.dev/blog/module-compatibility#working-with-interfaces). + +### Testing + +The tests should never leak goroutines. + +Use the term `ConcurrentSafe` in the test name when it aims to verify the +absence of race conditions. The top-level tests with this term will be run +many times in the `test-concurrent-safe` CI job to increase the chance of +catching concurrency issues. This does not apply to subtests when this term +is not in their root name. + +### Internal packages + +The use of internal packages should be scoped to a single module. A sub-module +should never import from a parent internal package. This creates a coupling +between the two modules where a user can upgrade the parent without the child +and if the internal package API has changed it will fail to upgrade[^3]. + +There are two known exceptions to this rule: + +- `go.opentelemetry.io/otel/internal/global` + - This package manages global state for all of opentelemetry-go. It needs to + be a single package in order to ensure the uniqueness of the global state. +- `go.opentelemetry.io/otel/internal/baggage` + - This package provides values in a `context.Context` that need to be + recognized by `go.opentelemetry.io/otel/baggage` and + `go.opentelemetry.io/otel/bridge/opentracing` but remain private. + +If you have duplicate code in multiple modules, make that code into a Go +template stored in `go.opentelemetry.io/otel/internal/shared` and use [gotmpl] +to render the templates in the desired locations. See [#4404] for an example of +this. + +[^3]: https://github.com/open-telemetry/opentelemetry-go/issues/3548 + +### Ignoring context cancellation + +OpenTelemetry API implementations need to ignore the cancellation of the context that are +passed when recording a value (e.g. starting a span, recording a measurement, emitting a log). +Recording methods should not return an error describing the cancellation state of the context +when they complete, nor should they abort any work. + +This rule may not apply if the OpenTelemetry specification defines a timeout mechanism for +the method. In that case the context cancellation can be used for the timeout with the +restriction that this behavior is documented for the method. Otherwise, timeouts +are expected to be handled by the user calling the API, not the implementation. + +Stoppage of the telemetry pipeline is handled by calling the appropriate `Shutdown` method +of a provider. It is assumed the context passed from a user is not used for this purpose. + +Outside of the direct recording of telemetry from the API (e.g. exporting telemetry, +force flushing telemetry, shutting down a signal provider) the context cancellation +should be honored. This means all work done on behalf of the user provided context +should be canceled. + +## Approvers and Maintainers + +### Triagers + +- [Cheng-Zhen Yang](https://github.com/scorpionknifes),

This project allows you to do just that for applications written in +Go. There are two steps to this process: instrument your application, and +configure an exporter. + +### Instrumentation + +To start capturing distributed traces and metric events from your application +it first needs to be instrumented. The easiest way to do this is by using an +instrumentation library for your code. Be sure to check out [the officially +supported instrumentation +libraries](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation). + +If you need to extend the telemetry an instrumentation library provides or want +to build your own instrumentation for your application directly you will need +to use the +[Go otel](https://pkg.go.dev/go.opentelemetry.io/otel) +package. The [examples](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/examples) +are a good way to see some practical uses of this process. + +### Export + +Now that your application is instrumented to collect telemetry, it needs an +export pipeline to send that telemetry to an observability platform. + +All officially supported exporters for the OpenTelemetry project are contained in the [exporters directory](./exporters). + +| Exporter | Logs | Metrics | Traces | +|---------------------------------------|:----:|:-------:|:------:| +| [OTLP](./exporters/otlp/) | ✓ | ✓ | ✓ | +| [Prometheus](./exporters/prometheus/) | | ✓ | | +| [stdout](./exporters/stdout/) | ✓ | ✓ | ✓ | +| [Zipkin](./exporters/zipkin/) | | | ✓ | + +## Contributing + +See the [contributing documentation](CONTRIBUTING.md). diff --git a/vendor/go.opentelemetry.io/otel/RELEASING.md b/vendor/go.opentelemetry.io/otel/RELEASING.md new file mode 100644 index 000000000..1e13ae54f --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/RELEASING.md @@ -0,0 +1,132 @@ +# Release Process + +## Semantic Convention Generation + +New versions of the [OpenTelemetry Semantic Conventions] mean new versions of the `semconv` package need to be generated. +The `semconv-generate` make target is used for this. + +1.

This project is simplified to include only the following +modules and their versions: + +* `otel`: `v0.14.0` +* `otel/trace`: `v0.14.0` +* `otel/metric`: `v0.14.0` +* `otel/baggage`: `v0.14.0` +* `otel/sdk/trace`: `v0.14.0` +* `otel/sdk/metric`: `v0.14.0` + +These modules have been developed to a point where the `otel/trace`, +`otel/baggage`, and `otel/sdk/trace` modules have reached a point that they +should be considered for a stable release. The `otel/metric` and +`otel/sdk/metric` are still under active development and the `otel` module +depends on both `otel/trace` and `otel/metric`. + +The `otel` package is refactored to remove its dependencies on `otel/metric` so +it can be released as stable as well. With that done the following release +candidates are made: + +* `otel`: `v1.0.0-RC1` +* `otel/trace`: `v1.0.0-RC1` +* `otel/baggage`: `v1.0.0-RC1` +* `otel/sdk/trace`: `v1.0.0-RC1` + +The `otel/metric` and `otel/sdk/metric` modules remain at `v0.14.0`. + +A few minor issues are discovered in the `otel/trace` package. These issues are +resolved with some minor, but backwards incompatible, changes and are released +as a second release candidate: + +* `otel`: `v1.0.0-RC2` +* `otel/trace`: `v1.0.0-RC2` +* `otel/baggage`: `v1.0.0-RC2` +* `otel/sdk/trace`: `v1.0.0-RC2` + +Notice that all module version numbers are incremented to adhere to our +versioning policy. + +After these release candidates have been evaluated to satisfaction, they are +released as version `v1.0.0`. + +* `otel`: `v1.0.0` +* `otel/trace`: `v1.0.0` +* `otel/baggage`: `v1.0.0` +* `otel/sdk/trace`: `v1.0.0` + +Since both the `go` utility and the Go module system support [the semantic +versioning definition of +precedence](https://semver.org/spec/v2.0.0.html#spec-item-11), this release +will correctly be interpreted as the successor to the previous release +candidates. + +Active development of this project continues. The `otel/metric` module now has +backwards incompatible changes to its API that need to be released and the +`otel/baggage` module has a minor bug fix that needs to be released. The +following release is made: + +* `otel`: `v1.0.1` +* `otel/trace`: `v1.0.1` +* `otel/metric`: `v0.15.0` +* `otel/baggage`: `v1.0.1` +* `otel/sdk/trace`: `v1.0.1` +* `otel/sdk/metric`: `v0.15.0` + +Notice that, again, all stable module versions are incremented in unison and +the `otel/sdk/metric` package, which depends on the `otel/metric` package, also +bumped its version. This bump of the `otel/sdk/metric` package makes sense +given their coupling, though it is not explicitly required by our versioning +policy. + +As we progress, the `otel/metric` and `otel/sdk/metric` packages have reached a +point where they should be evaluated for stability. The `otel` module is +reintegrated with the `otel/metric` package and the following release is made: + +* `otel`: `v1.1.0-RC1` +* `otel/trace`: `v1.1.0-RC1` +* `otel/metric`: `v1.1.0-RC1` +* `otel/baggage`: `v1.1.0-RC1` +* `otel/sdk/trace`: `v1.1.0-RC1` +* `otel/sdk/metric`: `v1.1.0-RC1` + +All the modules are evaluated and determined to a viable stable release. They +are then released as version `v1.1.0` (the minor version is incremented to +indicate the addition of new signal). + +* `otel`: `v1.1.0` +* `otel/trace`: `v1.1.0` +* `otel/metric`: `v1.1.0` +* `otel/baggage`: `v1.1.0` +* `otel/sdk/trace`: `v1.1.0` +* `otel/sdk/metric`: `v1.1.0` diff --git a/vendor/go.opentelemetry.io/otel/baggage/README.md b/vendor/go.opentelemetry.io/otel/baggage/README.md new file mode 100644 index 000000000..7d798435e --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/baggage/README.md @@ -0,0 +1,3 @@ +# Baggage + +[![PkgGoDev](https://pkg.go.dev/badge/go.opentelemetry.io/otel/baggage)](https://pkg.go.dev/go.opentelemetry.io/otel/baggage) diff --git a/vendor/go.opentelemetry.io/otel/baggage/baggage.go b/vendor/go.opentelemetry.io/otel/baggage/baggage.go new file mode 100644 index 000000000..0e1fe2422 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/baggage/baggage.go @@ -0,0 +1,1018 @@ +// Copyright The OpenTelemetry Authors +// SPDX-License-Identifier: Apache-2.0 + +package baggage // import "go.opentelemetry.io/otel/baggage" + +import ( + "errors" + "fmt" + "net/url" + "strings" + "unicode/utf8" + + "go.opentelemetry.io/otel/internal/baggage" +) + +const ( + maxMembers = 180 + maxBytesPerMembers = 4096 + maxBytesPerBaggageString = 8192 + + listDelimiter = "," + keyValueDelimiter = "=" + propertyDelimiter = ";" +) + +var ( + errInvalidKey = errors.New("invalid key") + errInvalidValue = errors.New("invalid value") + errInvalidProperty = errors.New("invalid baggage list-member property") + errInvalidMember = errors.New("invalid baggage list-member") + errMemberNumber = errors.New("too many list-members in baggage-string") + errMemberBytes = errors.New("list-member too large") + errBaggageBytes = errors.New("baggage-string too large") +) + +// Property is an additional metadata entry for a baggage list-member. +type Property struct { + key, value string + + // hasValue indicates if a zero-value value means the property does not + // have a value or if it was the zero-value. + hasValue bool +} + +// NewKeyProperty returns a new Property for key. +// +// The passed key must be valid, non-empty UTF-8 string. +// If key is invalid, an error will be returned. +// However, the specific Propagators that are used to transmit baggage entries across +// component boundaries may impose their own restrictions on Property key. +// For example, the W3C Baggage specification restricts the Property keys to strings that +// satisfy the token definition from RFC7230, Section 3.2.6. +// For maximum compatibility, alphanumeric value are strongly recommended to be used as Property key. +func NewKeyProperty(key string) (Property, error) { + if !validateBaggageName(key) { + return newInvalidProperty(), fmt.Errorf("%w: %q", errInvalidKey, key) + } + + p := Property{key: key} + return p, nil +} + +// NewKeyValueProperty returns a new Property for key with value. +// +// The passed key must be compliant with W3C Baggage specification. +// The passed value must be percent-encoded as defined in W3C Baggage specification. +// +// Notice: Consider using [NewKeyValuePropertyRaw] instead +// that does not require percent-encoding of the value. +func NewKeyValueProperty(key, value string) (Property, error) { + if !validateKey(key) { + return newInvalidProperty(), fmt.Errorf("%w: %q", errInvalidKey, key) + } + + if !validateValue(value) { + return newInvalidProperty(), fmt.Errorf("%w: %q", errInvalidValue, value) + } + decodedValue, err := url.PathUnescape(value) + if err != nil { + return newInvalidProperty(), fmt.Errorf("%w: %q", errInvalidValue, value) + } + return NewKeyValuePropertyRaw(key, decodedValue) +} + +// NewKeyValuePropertyRaw returns a new Property for key with value. +// +// The passed key must be valid, non-empty UTF-8 string. +// The passed value must be valid UTF-8 string. +// However, the specific Propagators that are used to transmit baggage entries across +// component boundaries may impose their own restrictions on Property key. +// For example, the W3C Baggage specification restricts the Property keys to strings that +// satisfy the token definition from RFC7230, Section 3.2.6. +// For maximum compatibility, alphanumeric value are strongly recommended to be used as Property key. +func NewKeyValuePropertyRaw(key, value string) (Property, error) { + if !validateBaggageName(key) { + return newInvalidProperty(), fmt.Errorf("%w: %q", errInvalidKey, key) + } + if !validateBaggageValue(value) { + return newInvalidProperty(), fmt.Errorf("%w: %q", errInvalidValue, value) + } + + p := Property{ + key: key, + value: value, + hasValue: true, + } + return p, nil +} + +func newInvalidProperty() Property { + return Property{} +} + +// parseProperty attempts to decode a Property from the passed string.

See [go.opentelemetry.io/otel/sdk/metric] for the official +OpenTelemetry implementation of this API. + +All measurements made with this package are made via instruments. These +instruments are created by a [Meter] which itself is created by a +[MeterProvider]. Applications need to accept a [MeterProvider] implementation +as a starting point when instrumenting. This can be done directly, or by using +the OpenTelemetry global MeterProvider via [GetMeterProvider]. Using an +appropriately named [Meter] from the accepted [MeterProvider], instrumentation +can then be built from the [Meter]'s instruments. + +# Instruments + +Each instrument is designed to make measurements of a particular type. Broadly, +all instruments fall into two overlapping logical categories: asynchronous or +synchronous, and int64 or float64. + +All synchronous instruments ([Int64Counter], [Int64UpDownCounter], +[Int64Histogram], [Float64Counter], [Float64UpDownCounter], and +[Float64Histogram]) are used to measure the operation and performance of source +code during the source code execution. These instruments only make measurements +when the source code they instrument is run. + +All asynchronous instruments ([Int64ObservableCounter], +[Int64ObservableUpDownCounter], [Int64ObservableGauge], +[Float64ObservableCounter], [Float64ObservableUpDownCounter], and +[Float64ObservableGauge]) are used to measure metrics outside of the execution +of source code. They are said to make "observations" via a callback function +called once every measurement collection cycle. + +Each instrument is also grouped by the value type it measures. Either int64 or +float64. The value being measured will dictate which instrument in these +categories to use. + +Outside of these two broad categories, instruments are described by the +function they are designed to serve. All Counters ([Int64Counter], +[Float64Counter], [Int64ObservableCounter], and [Float64ObservableCounter]) are +designed to measure values that never decrease in value, but instead only +incrementally increase in value. UpDownCounters ([Int64UpDownCounter], +[Float64UpDownCounter], [Int64ObservableUpDownCounter], and +[Float64ObservableUpDownCounter]) on the other hand, are designed to measure +values that can increase and decrease. When more information needs to be +conveyed about all the synchronous measurements made during a collection cycle, +a Histogram ([Int64Histogram] and [Float64Histogram]) should be used. Finally, +when just the most recent measurement needs to be conveyed about an +asynchronous measurement, a Gauge ([Int64ObservableGauge] and +[Float64ObservableGauge]) should be used. + +See the [OpenTelemetry documentation] for more information about instruments +and their intended use. + +# Instrument Name + +OpenTelemetry defines an [instrument name syntax] that restricts what +instrument names are allowed. + +Instrument names should ... + + - Not be empty. + - Have an alphabetic character as their first letter. + - Have any letter after the first be an alphanumeric character, ‘_’, ‘.’, + ‘-’, or ‘/’. + - Have a maximum length of 255 letters. + +To ensure compatibility with observability platforms, all instruments created +need to conform to this syntax. Not all implementations of the API will validate +these names, it is the callers responsibility to ensure compliance. + +# Measurements + +Measurements are made by recording values and information about the values with +an instrument. How these measurements are recorded depends on the instrument. + +Measurements for synchronous instruments ([Int64Counter], [Int64UpDownCounter], +[Int64Histogram], [Float64Counter], [Float64UpDownCounter], and +[Float64Histogram]) are recorded using the instrument methods directly. All +counter instruments have an Add method that is used to measure an increment +value, and all histogram instruments have a Record method to measure a data +point. + +Asynchronous instruments ([Int64ObservableCounter], +[Int64ObservableUpDownCounter], [Int64ObservableGauge], +[Float64ObservableCounter], [Float64ObservableUpDownCounter], and +[Float64ObservableGauge]) record measurements within a callback function. The +callback is registered with the Meter which ensures the callback is called once +per collection cycle. A callback can be registered two ways: during the +instrument's creation using an option, or later using the RegisterCallback +method of the [Meter] that created the instrument. + +If the following criteria are met, an option ([WithInt64Callback] or +[WithFloat64Callback]) can be used during the asynchronous instrument's +creation to register a callback ([Int64Callback] or [Float64Callback], +respectively): + + - The measurement process is known when the instrument is created + - Only that instrument will make a measurement within the callback + - The callback never needs to be unregistered + +If the criteria are not met, use the RegisterCallback method of the [Meter] that +created the instrument to register a [Callback]. + +# API Implementations + +This package does not conform to the standard Go versioning policy, all of its +interfaces may have methods added to them without a package major version bump. +This non-standard API evolution could surprise an uninformed implementation +author. They could unknowingly build their implementation in a way that would +result in a runtime panic for their users that update to the new API. + +The API is designed to help inform an instrumentation author about this +non-standard API evolution. It requires them to choose a default behavior for +unimplemented interface methods. There are three behavior choices they can +make: + + - Compilation failure + - Panic + - Default to another implementation + +All interfaces in this API embed a corresponding interface from +[go.opentelemetry.io/otel/metric/embedded]. If an author wants the default +behavior of their implementations to be a compilation failure, signaling to +their users they need to update to the latest version of that implementation, +they need to embed the corresponding interface from +[go.opentelemetry.io/otel/metric/embedded] in their implementation.

We often times receive PRs that are trying to fix several things at + a time, but only one fix is considered acceptable, nothing gets merged and + both author's & review's time is wasted. Create more PRs to address different + concerns and everyone will be happy. + +- If you are searching for features to work on, issues labeled [Status: Help + Wanted](https://github.com/grpc/grpc-go/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22Status%3A+Help+Wanted%22) + is a great place to start. These issues are well-documented and usually can be + resolved with a single pull request. + +- If you are adding a new file, make sure it has the copyright message template + at the top as a comment. You can copy over the message from an existing file + and update the year. + +- The grpc package should only depend on standard Go packages and a small number + of exceptions. If your contribution introduces new dependencies which are NOT + in the [list](https://godoc.org/google.golang.org/grpc?imports), you need a + discussion with gRPC-Go authors and consultants. + +- For speculative changes, consider opening an issue and discussing it first. If + you are suggesting a behavioral or API change, consider starting with a [gRFC + proposal](https://github.com/grpc/proposal). + +- Provide a good **PR description** as a record of **what** change is being made + and **why** it was made. Link to a GitHub issue if it exists. + +- If you want to fix formatting or style, consider whether your changes are an + obvious improvement or might be considered a personal preference. If a style + change is based on preference, it likely will not be accepted. If it corrects + widely agreed-upon anti-patterns, then please do create a PR and explain the + benefits of the change. + +- Unless your PR is trivial, you should expect there will be reviewer comments + that you'll need to address before merging. We'll mark it as `Status: Requires + Reporter Clarification` if we expect you to respond to these comments in a + timely manner. If the PR remains inactive for 6 days, it will be marked as + `stale` and automatically close 7 days after that if we don't hear back from + you. + +- Maintain **clean commit history** and use **meaningful commit messages**. PRs + with messy commit history are difficult to review and won't be merged. Use + `rebase -i upstream/master` to curate your commit history and/or to bring in + latest changes from master (but avoid rebasing in the middle of a code + review). + +- Keep your PR up to date with upstream/master (if there are merge conflicts, we + can't really merge your change). + +- **All tests need to be passing** before your change can be merged. We + recommend you **run tests locally** before creating your PR to catch breakages + early on. + - `./scripts/vet.sh` to catch vet errors + - `go test -cpu 1,4 -timeout 7m ./...` to run the tests + - `go test -race -cpu 1,4 -timeout 7m ./...` to run tests in race mode + +- Exceptions to the rules can be made if there's a compelling reason for doing so. diff --git a/vendor/google.golang.org/grpc/GOVERNANCE.md b/vendor/google.golang.org/grpc/GOVERNANCE.md new file mode 100644 index 000000000..d6ff26747 --- /dev/null +++ b/vendor/google.golang.org/grpc/GOVERNANCE.md @@ -0,0 +1 @@ +This repository is governed by the gRPC organization's [governance rules](https://github.com/grpc/grpc-community/blob/master/governance.md). diff --git a/vendor/google.golang.org/grpc/LICENSE b/vendor/google.golang.org/grpc/LICENSE new file mode 100644 index 000000000..d64569567 --- /dev/null +++ b/vendor/google.golang.org/grpc/LICENSE @@ -0,0 +1,202 @@ + + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

For example, if the mask in the previous +// example is applied to a response message as follows: +// +// f { +// a : 22 +// b { +// d : 1 +// x : 2 +// } +// y : 13 +// } +// z: 8 +// +// The result will not contain specific values for fields x,y and z +// (their value will be set to the default, and omitted in proto text +// output): +// +// f { +// a : 22 +// b { +// d : 1 +// } +// } +// +// A repeated field is not allowed except at the last position of a +// paths string. +// +// If a FieldMask object is not present in a get operation, the +// operation applies to all fields (as if a FieldMask of all fields +// had been specified). +// +// Note that a field mask does not necessarily apply to the +// top-level response message. In case of a REST get operation, the +// field mask applies directly to the response, but in case of a REST +// list operation, the mask instead applies to each individual message +// in the returned resource list. In case of a REST custom method, +// other definitions may be used. Where the mask applies will be +// clearly documented together with its declaration in the API. In +// any case, the effect on the returned resource/resources is required +// behavior for APIs. +// +// # Field Masks in Update Operations +// +// A field mask in update operations specifies which fields of the +// targeted resource are going to be updated. The API is required +// to only change the values of the fields as specified in the mask +// and leave the others untouched. If a resource is passed in to +// describe the updated values, the API ignores the values of all +// fields not covered by the mask. +// +// If a repeated field is specified for an update operation, new values will +// be appended to the existing repeated field in the target resource. Note that +// a repeated field is only allowed in the last position of a `paths` string. +// +// If a sub-message is specified in the last position of the field mask for an +// update operation, then new value will be merged into the existing sub-message +// in the target resource. +// +// For example, given the target message: +// +// f { +// b { +// d: 1 +// x: 2 +// } +// c: [1] +// } +// +// And an update message: +// +// f { +// b { +// d: 10 +// } +// c: [2] +// } +// +// then if the field mask is: +// +// paths: ["f.b", "f.c"] +// +// then the result will be: +// +// f { +// b { +// d: 10 +// x: 2 +// } +// c: [1, 2] +// } +// +// An implementation may provide options to override this default behavior for +// repeated and message fields. +// +// In order to reset a field's value to the default, the field must +// be in the mask and set to the default value in the provided resource. +// Hence, in order to reset all fields of a resource, provide a default +// instance of the resource and set all fields in the mask, or do +// not provide a mask as described below. +// +// If a field mask is not present on update, the operation applies to +// all fields (as if a field mask of all fields has been specified). +// Note that in the presence of schema evolution, this may mean that +// fields the client does not know and has therefore not filled into +// the request will be reset to their default. If this is unwanted +// behavior, a specific service may require a client to always specify +// a field mask, producing an error if not. +// +// As with get operations, the location of the resource which +// describes the updated values in the request message depends on the +// operation kind. In any case, the effect of the field mask is +// required to be honored by the API. +// +// ## Considerations for HTTP REST +// +// The HTTP kind of an update operation which uses a field mask must +// be set to PATCH instead of PUT in order to satisfy HTTP semantics +// (PUT must only be used for full updates). +// +// # JSON Encoding of Field Masks +// +// In JSON, a field mask is encoded as a single string where paths are +// separated by a comma. Fields name in each path are converted +// to/from lower-camel naming conventions. +// +// As an example, consider the following message declarations: +// +// message Profile { +// User user = 1; +// Photo photo = 2; +// } +// message User { +// string display_name = 1; +// string address = 2; +// } +// +// In proto a field mask for `Profile` may look as such: +// +// mask { +// paths: "user.display_name" +// paths: "photo" +// } +// +// In JSON, the same mask is represented as below: +// +// { +// mask: "user.displayName,photo" +// } +// +// # Field Masks and Oneof Fields +// +// Field masks treat fields in oneofs just as regular fields. Consider the +// following message: +// +// message SampleMessage { +// oneof test_oneof { +// string name = 4; +// SubMessage sub_message = 9; +// } +// } +// +// The field mask can be: +// +// mask { +// paths: "name" +// } +// +// Or: +// +// mask { +// paths: "sub_message" +// } +// +// Note that oneof type names ("test_oneof" in this case) cannot be used in +// paths. +// +// ## Field Mask Verification +// +// The implementation of any API method which has a FieldMask type field in the +// request should verify the included field paths, and return an +// `INVALID_ARGUMENT` error if any path is unmappable. +type FieldMask struct { + state protoimpl.MessageState `protogen:"open.v1"` + // The set of field mask paths. + Paths []string `protobuf:"bytes,1,rep,name=paths,proto3" json:"paths,omitempty"` + unknownFields protoimpl.UnknownFields + sizeCache protoimpl.SizeCache +} + +// New constructs a field mask from a list of paths and verifies that +// each one is valid according to the specified message type. +func New(m proto.Message, paths ...string) (*FieldMask, error) { + x := new(FieldMask) + return x, x.Append(m, paths...) +} + +// Union returns the union of all the paths in the input field masks. +func Union(mx *FieldMask, my *FieldMask, ms ...*FieldMask) *FieldMask { + var out []string + out = append(out, mx.GetPaths()...) + out = append(out, my.GetPaths()...) + for _, m := range ms { + out = append(out, m.GetPaths()...) + } + return &FieldMask{Paths: normalizePaths(out)} +} + +// Intersect returns the intersection of all the paths in the input field masks. +func Intersect(mx *FieldMask, my *FieldMask, ms ...*FieldMask) *FieldMask { + var ss1, ss2 []string // reused buffers for performance + intersect := func(out, in []string) []string { + ss1 = normalizePaths(append(ss1[:0], in...)) + ss2 = normalizePaths(append(ss2[:0], out...)) + out = out[:0] + for i1, i2 := 0, 0;
