### 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)
|
|

- Nested array/slice support has been removed. (#1226)
|
|
|
|
## [0.12.0] - 2020-09-24
|
|
|
|
### Added
|
|
|
|
- A `SpanConfigure` function in `go.opentelemetry.io/otel/api/trace` to create a new `SpanConfig` from `SpanOption`s. (#1108)
|
|
- In the `go.opentelemetry.io/otel/api/trace` package, `NewTracerConfig` was added to construct new `TracerConfig`s.
|
|
This addition was made to conform with our project option conventions. (#1155)
|
|
- Instrumentation library information was added to the Zipkin exporter. (#1119)
|
|
- The `SpanProcessor` interface now has a `ForceFlush()` method. (#1166)
|
|
- More semantic conventions for k8s as resource attributes. (#1167)
|
|
|
|
### Changed
|
|
|
|
- Add reconnecting udp connection type to Jaeger exporter.
|
|
This change adds a new optional implementation of the udp conn interface used to detect changes to an agent's host dns record.
|
|
It then adopts the new destination address to ensure the exporter doesn't get stuck. This change was ported from jaegertracing/jaeger-client-go#520. (#1063)
|
|
- Replace `StartOption` and `EndOption` in `go.opentelemetry.io/otel/api/trace` with `SpanOption`.
|
|
This change is matched by replacing the `StartConfig` and `EndConfig` with a unified `SpanConfig`. (#1108)
|
|
- Replace the `LinkedTo` span option in `go.opentelemetry.io/otel/api/trace` with `WithLinks`.
|
|
This is be more consistent with our other option patterns, i.e. passing the item to be configured directly instead of its component parts, and provides a cleaner function signature. (#1108)
|
|
- The `go.opentelemetry.io/otel/api/trace` `TracerOption` was changed to an interface to conform to project option conventions. (#1109)
|
|
- Move the `B3` and `TraceContext` from within the `go.opentelemetry.io/otel/api/trace` package to their own `go.opentelemetry.io/otel/propagators` package.
|
|
This removal of the propagators is reflective of the OpenTelemetry specification for these propagators as well as cleans up the `go.opentelemetry.io/otel/api/trace` API. (#1118)
|
|
- Rename Jaeger tags used for instrumentation library information to reflect changes in OpenTelemetry specification. (#1119)
|
|
- Rename `ProbabilitySampler` to `TraceIDRatioBased` and change semantics to ignore parent span sampling status. (#1115)
|
|
- Move `tools` package under `internal`. (#1141)
|
|
- Move `go.opentelemetry.io/otel/api/correlation` package to `go.opentelemetry.io/otel/api/baggage`. (#1142)
|
|
The `correlation.CorrelationContext` propagator has been renamed `baggage.Baggage`. Other exported functions and types are unchanged.
|
|
- Rename `ParentOrElse` sampler to `ParentBased` and allow setting samplers depending on parent span. (#1153)
|
|
- In the `go.opentelemetry.io/otel/api/trace` package, `SpanConfigure` was renamed to `NewSpanConfig`. (#1155)
|
|
- Change `dependabot.yml` to add a `Skip Changelog` label to dependabot-sourced PRs. (#1161)
|
|
- The [configuration style guide](https://github.com/open-telemetry/opentelemetry-go/blob/master/CONTRIBUTING.md#config) has been updated to
|
|
recommend the use of `newConfig()` instead of `configure()`. (#1163)
|
|
- The `otlp.Config` type has been unexported and changed to `otlp.config`, along with its initializer. (#1163)
|
|
- Ensure exported interface types include parameter names and update the
|
|
Style Guide to reflect this styling rule. (#1172)
|
|
- Don't consider unset environment variable for resource detection to be an error. (#1170)
|
|
- Rename `go.opentelemetry.io/otel/api/metric.ConfigureInstrument` to `NewInstrumentConfig` and
|
|
`go.opentelemetry.io/otel/api/metric.ConfigureMeter` to `NewMeterConfig`.
|
|
- ValueObserver instruments use LastValue aggregator by default. (#1165)
|
|
- OTLP Metric exporter supports LastValue aggregation. (#1165)
|
|
- Move the `go.opentelemetry.io/otel/api/unit` package to `go.opentelemetry.io/otel/unit`. (#1185)
|
|
- Rename `Provider` to `MeterProvider` in the `go.opentelemetry.io/otel/api/metric` package. (#1190)
|
|
- Rename `NoopProvider` to `NoopMeterProvider` in the `go.opentelemetry.io/otel/api/metric` package. (#1190)
|
|
- Rename `NewProvider` to `NewMeterProvider` in the `go.opentelemetry.io/otel/api/metric/metrictest` package. (#1190)
|
|
- Rename `Provider` to `MeterProvider` in the `go.opentelemetry.io/otel/api/metric/registry` package. (#1190)
|
|
- Rename `NewProvider` to `NewMeterProvider` in the `go.opentelemetry.io/otel/api/metri/registryc` package. (#1190)
|
|
- Rename `Provider` to `TracerProvider` in the `go.opentelemetry.io/otel/api/trace` package. (#1190)
|
|
- Rename `NoopProvider` to `NoopTracerProvider` in the `go.opentelemetry.io/otel/api/trace` package. (#1190)
|
|
- Rename `Provider` to `TracerProvider` in the `go.opentelemetry.io/otel/api/trace/tracetest` package. (#1190)
|

- Rename `NewProvider` to `NewTracerProvider` in the `go.opentelemetry.io/otel/api/trace/tracetest` package. (#1190)
|
|
- Rename `WrapperProvider` to `WrapperTracerProvider` in the `go.opentelemetry.io/otel/bridge/opentracing` package. (#1190)
|
|
- Rename `NewWrapperProvider` to `NewWrapperTracerProvider` in the `go.opentelemetry.io/otel/bridge/opentracing` package. (#1190)

|
|
- Rename `Provider` method of the push controller to `MeterProvider` in the `go.opentelemetry.io/otel/sdk/metric/controller/push` package. (#1190)
|
|
- Rename `ProviderOptions` to `TracerProviderConfig` in the `go.opentelemetry.io/otel/sdk/trace` package. (#1190)

|
|
- Add test of spans being processed by the `SpanProcessor`s in the order they were registered. (#1203)
|
|
|
|
### Removed
|
|
|
|
- Remove the B3 propagator from `go.opentelemetry.io/otel/propagators`. It is now located in the
|
|
`go.opentelemetry.io/contrib/propagators/` module. (#1191)
|
|
- Remove the semantic convention for HTTP status text, `HTTPStatusTextKey` from package `go.opentelemetry.io/otel/semconv`. (#1194)
|
|
|
|
### Fixed
|
|
|
|
- Zipkin example no longer mentions `ParentSampler`, corrected to `ParentBased`. (#1171)
|
|
- Fix missing shutdown processor in otel-collector example. (#1186)
|
|
- Fix missing shutdown processor in basic and namedtracer examples. (#1197)
|
|
|
|
## [0.11.0] - 2020-08-24
|
|
|
|
### Added
|
|
|
|
- Support for exporting array-valued attributes via OTLP. (#992)
|
|
- `Noop` and `InMemory` `SpanBatcher` implementations to help with testing integrations. (#994)
|
|
- Support for filtering metric label sets. (#1047)
|
|
- A dimensionality-reducing metric Processor. (#1057)
|
|
- Integration tests for more OTel Collector Attribute types. (#1062)
|
|
- A new `WithSpanProcessor` `ProviderOption` is added to the `go.opentelemetry.io/otel/sdk/trace` package to create a `Provider` and automatically register the `SpanProcessor`. (#1078)
|
|
|
|
### Changed
|
|
|
|
- Rename `sdk/metric/processor/test` to `sdk/metric/processor/processortest`. (#1049)
|
|
- Rename `sdk/metric/controller/test` to `sdk/metric/controller/controllertest`. (#1049)
|
|
- Rename `api/testharness` to `api/apitest`. (#1049)
|
|
- Rename `api/trace/testtrace` to `api/trace/tracetest`. (#1049)
|
|
- Change Metric Processor to merge multiple observations. (#1024)
|
|
- The `go.opentelemetry.io/otel/bridge/opentracing` bridge package has been made into its own module.
|
|
This removes the package dependencies of this bridge from the rest of the OpenTelemetry based project. (#1038)
|
|
- Renamed `go.opentelemetry.io/otel/api/standard` package to `go.opentelemetry.io/otel/semconv` to avoid the ambiguous and generic name `standard` and better describe the package as containing OpenTelemetry semantic conventions. (#1016)
|
|
- The environment variable used for resource detection has been changed from `OTEL_RESOURCE_LABELS` to `OTEL_RESOURCE_ATTRIBUTES` (#1042)
|
|
- Replace `WithSyncer` with `WithBatcher` in examples. (#1044)
|
|
- Replace the `google.golang.org/grpc/codes` dependency in the API with an equivalent `go.opentelemetry.io/otel/codes` package. (#1046)
|
|
- Merge the `go.opentelemetry.io/otel/api/label` and `go.opentelemetry.io/otel/api/kv` into the new `go.opentelemetry.io/otel/label` package. (#1060)
|
|
- Unify Callback Function Naming.
|
|
Rename `*Callback` with `*Func`. (#1061)
|
|
- CI builds validate against last two versions of Go, dropping 1.13 and adding 1.15. (#1064)
|
|
- The `go.opentelemetry.io/otel/sdk/export/trace` interfaces `SpanSyncer` and `SpanBatcher` have been replaced with a specification compliant `Exporter` interface.
|
|
This interface still supports the export of `SpanData`, but only as a slice.
|
|
Implementation are also required now to return any error from `ExportSpans` if one occurs as well as implement a `Shutdown` method for exporter clean-up. (#1078)
|
|
- The `go.opentelemetry.io/otel/sdk/trace` `NewBatchSpanProcessor` function no longer returns an error.
|
|
If a `nil` exporter is passed as an argument to this function, instead of it returning an error, it now returns a `BatchSpanProcessor` that handles the export of `SpanData` by not taking any action. (#1078)
|
|
- The `go.opentelemetry.io/otel/sdk/trace` `NewProvider` function to create a `Provider` no longer returns an error, instead only a `*Provider`.
|
|
This change is related to `NewBatchSpanProcessor` not returning an error which was the only error this function would return. (#1078)
|
|
|
|
### Removed
|
|
|
|
- Duplicate, unused API sampler interface. (#999)
|
|
Use the [`Sampler` interface](https://github.com/open-telemetry/opentelemetry-go/blob/v0.11.0/sdk/trace/sampling.go) provided by the SDK instead.
|
|
- The `grpctrace` instrumentation was moved to the `go.opentelemetry.io/contrib` repository and out of this repository.
|
|
This move includes moving the `grpc` example to the `go.opentelemetry.io/contrib` as well. (#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`. (#1032)
|
|
|
|
### Fixed
|
|
|
|
- The `semconv.HTTPServerMetricAttributesFromHTTPRequest()` function no longer generates the high-cardinality `http.request.content.length` label. (#1031)
|
|
- Correct instrumentation version tag in Jaeger exporter. (#1037)
|
|
- The SDK span will now set an error event if the `End` method is called during a panic (i.e. it was deferred). (#1043)
|
|
- Move internally generated protobuf code from the `go.opentelemetry.io/otel` to the OTLP exporter to reduce dependency overhead. (#1050)
|
|
- The `otel-collector` example referenced outdated collector processors. (#1006)
|
|
|
|
## [0.10.0] - 2020-07-29
|
|
|
|
This release migrates the default OpenTelemetry SDK into its own Go module, decoupling the SDK from the API and reducing dependencies for instrumentation packages.
|
|
|
|
### Added
|
|
|
|
- The Zipkin exporter now has `NewExportPipeline` and `InstallNewPipeline` constructor functions to match the common pattern.
|
|
These function build a new exporter with default SDK options and register the exporter with the `global` package respectively. (#944)
|
|
- Add propagator option for gRPC instrumentation. (#986)
|
|
- The `testtrace` package now tracks the `trace.SpanKind` for each span. (#987)
|
|
|
|
### Changed
|
|
|
|
- Replace the `RegisterGlobal` `Option` in the Jaeger exporter with an `InstallNewPipeline` constructor function.
|
|
This matches the other exporter constructor patterns and will register a new exporter after building it with default configuration. (#944)
|
|
- The trace (`go.opentelemetry.io/otel/exporters/trace/stdout`) and metric (`go.opentelemetry.io/otel/exporters/metric/stdout`) `stdout` exporters are now merged into a single exporter at `go.opentelemetry.io/otel/exporters/stdout`.
|
|
This new exporter was made into its own Go module to follow the pattern of all exporters and decouple it from the `go.opentelemetry.io/otel` module. (#956, #963)
|
|
- Move the `go.opentelemetry.io/otel/exporters/test` test package to `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#962)
|
|
- The `go.opentelemetry.io/otel/api/kv/value` package was merged into the parent `go.opentelemetry.io/otel/api/kv` package. (#968)
|
|
- `value.Bool` was replaced with `kv.BoolValue`.
|
|
- `value.Int64` was replaced with `kv.Int64Value`.
|
|
- `value.Uint64` was replaced with `kv.Uint64Value`.
|
|
- `value.Float64` was replaced with `kv.Float64Value`.
|
|
- `value.Int32` was replaced with `kv.Int32Value`.
|
|
- `value.Uint32` was replaced with `kv.Uint32Value`.
|
|
- `value.Float32` was replaced with `kv.Float32Value`.
|
|
- `value.String` was replaced with `kv.StringValue`.
|
|
- `value.Int` was replaced with `kv.IntValue`.
|
|
- `value.Uint` was replaced with `kv.UintValue`.
|
|
- `value.Array` was replaced with `kv.ArrayValue`.
|
|
- Rename `Infer` to `Any` in the `go.opentelemetry.io/otel/api/kv` package. (#972)
|
|
- Change `othttp` to use the `httpsnoop` package to wrap the `ResponseWriter` so that optional interfaces (`http.Hijacker`, `http.Flusher`, etc.) that are implemented by the original `ResponseWriter`are also implemented by the wrapped `ResponseWriter`. (#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. (#957)
|
|
- Use `global.Handle` for span export errors in the OTLP exporter. (#946)
|
|
- Correct Go language formatting in the README documentation. (#961)
|
|
- Remove default SDK dependencies from the `go.opentelemetry.io/otel/api` package. (#977)
|
|
- Remove default SDK dependencies from the `go.opentelemetry.io/otel/instrumentation` package. (#983)
|
|
- Move documented examples for `go.opentelemetry.io/otel/instrumentation/grpctrace` interceptors into Go example tests. (#984)
|
|
|
|
## [0.9.0] - 2020-07-20
|
|
|
|
### Added
|
|
|
|
- A new Resource Detector interface is included to allow resources to be automatically detected and included. (#939)
|
|
- A Detector to automatically detect resources from an environment variable. (#939)
|
|
- Github action to generate protobuf Go bindings locally in `internal/opentelemetry-proto-gen`. (#938)
|
|
- OTLP .proto files from `open-telemetry/opentelemetry-proto` imported as a git submodule under `internal/opentelemetry-proto`.
|
|
References to `github.com/open-telemetry/opentelemetry-proto` changed to `go.opentelemetry.io/otel/internal/opentelemetry-proto-gen`. (#942)
|
|
|
|
### Changed
|
|
|
|
- Non-nil value `struct`s for key-value pairs will be marshalled using JSON rather than `Sprintf`. (#948)
|
|
|
|
### Removed
|
|
|
|
- Removed dependency on `github.com/open-telemetry/opentelemetry-collector`. (#943)
|
|
|
|
## [0.8.0] - 2020-07-09
|
|
|
|
### Added
|
|
|
|
- The `B3Encoding` type to represent the B3 encoding(s) the B3 propagator can inject.
|
|
A value for HTTP supported encodings (Multiple Header: `MultipleHeader`, Single Header: `SingleHeader`) are included. (#882)
|
|
- The `FlagsDeferred` trace flag to indicate if the trace sampling decision has been deferred. (#882)
|
|
- The `FlagsDebug` trace flag to indicate if the trace is a debug trace. (#882)
|
|
- Add `peer.service` semantic attribute. (#898)
|
|
- Add database-specific semantic attributes. (#899)
|
|
- Add semantic convention for `faas.coldstart` and `container.id`. (#909)
|
|
- Add http content size semantic conventions. (#905)
|
|
- Include `http.request_content_length` in HTTP request basic attributes. (#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)
|
|
- Extend semantic conventions for RPC. (#900)
|
|
- To match constant naming conventions in the `api/standard` package, the `FaaS*` key names are appended with a suffix of `Key`. (#920)
|
|
- `"api/standard".FaaSName` -> `FaaSNameKey`
|
|
- `"api/standard".FaaSID` -> `FaaSIDKey`
|
|
- `"api/standard".FaaSVersion` -> `FaaSVersionKey`
|
|
- `"api/standard".FaaSInstance` -> `FaaSInstanceKey`
|
|
|
|
### Removed
|
|
|
|
- The `FlagsUnused` trace flag is removed.
|
|
The purpose of this flag was to act as the inverse of `FlagsSampled`, the inverse of `FlagsSampled` is used instead. (#882)
|
|
- The B3 header constants (`B3SingleHeader`, `B3DebugFlagHeader`, `B3TraceIDHeader`, `B3SpanIDHeader`, `B3SampledHeader`, `B3ParentSpanIDHeader`) are removed.
|
|
If B3 header keys are needed [the authoritative OpenZipkin package constants](https://pkg.go.dev/github.com/openzipkin/zipkin-go@v0.2.2/propagation/b3?tab=doc#pkg-constants) should be used instead. (#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. (#882)
|
|
- Bump github.com/itchyny/gojq from 0.10.3 to 0.10.4 in /tools. (#883)
|
|
- Bump github.com/opentracing/opentracing-go from v1.1.1-0.20190913142402-a7454ce5950e to v1.2.0. (#885)
|
|
- The tracing time conversion for OTLP spans is now correctly set to `UnixNano`. (#896)
|
|
- Ensure span status is not set to `Unknown` when no HTTP status code is provided as it is assumed to be `200 OK`. (#908)
|
|
- Ensure `httptrace.clientTracer` closes `http.headers` span. (#912)
|
|
- Prometheus exporter will not apply stale updates or forget inactive metrics. (#903)
|
|
- Add test for api.standard `HTTPClientAttributesFromHTTPRequest`. (#905)
|
|
- Bump github.com/golangci/golangci-lint from 1.27.0 to 1.28.1 in /tools. (#901, #913)
|
|
- Update otel-colector example to use the v0.5.0 collector. (#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. (#926)
|
|
- Bump github.com/golangci/golangci-lint from 1.28.1 to 1.28.2 in /tools. (#930)
|
|
|
|
## [0.7.0] - 2020-06-26
|
|
|
|
This release implements the v0.5.0 version of the OpenTelemetry specification.
|
|

### Added
|
|
|
|
- The othttp instrumentation now includes default metrics. (#861)
|
|
- This CHANGELOG file to track all changes in the project going forward.
|
|
- Support for array type attributes. (#798)
|
|
- Apply transitive dependabot go.mod dependency updates as part of a new automatic Github workflow. (#844)
|
|
- Timestamps are now passed to exporters for each export. (#835)
|
|
- Add new `Accumulation` type to metric SDK to transport telemetry from `Accumulator`s to `Processor`s.
|
|
This replaces the prior `Record` `struct` use for this purpose. (#835)
|
|
- New dependabot integration to automate package upgrades. (#814)
|
|
- `Meter` and `Tracer` implementations accept instrumentation version version as an optional argument.
|
|
This instrumentation version is passed on to exporters. (#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. (#784)
|
|
- The required `application/json` header for the Zipkin exporter is included in all exports. (#774)

|
### Changed
|
|
|
|
- Rename `Integrator` to `Processor` in the metric SDK. (#863)
|
|
- Rename `AggregationSelector` to `AggregatorSelector`. (#859)
|
|
- Rename `SynchronizedCopy` to `SynchronizedMove`. (#858)
|
|
- Rename `simple` integrator to `basic` integrator. (#857)
|
|
- Merge otlp collector examples. (#841)
|
|
- Change the metric SDK to support cumulative, delta, and pass-through exporters directly.
|
|
With these changes, cumulative and delta specific exporters are able to request the correct kind of aggregation from the SDK. (#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. (#810)
|
|
- Rename `sdk/export/metric/aggregator` to `sdk/export/metric/aggregation`. #808
|
|
- Send configured headers with every request in the OTLP exporter, instead of just on connection creation. (#806)
|
|
- Update error handling for any one off error handlers, replacing, instead, with the `global.Handle` function. (#791)
|
|
- Rename `plugin` directory to `instrumentation` to match the OpenTelemetry specification. (#779)
|
|
- Makes the argument order to Histogram and DDSketch `New()` consistent. (#781)
|
|
|
|
### Removed
|
|
|
|
- `Uint64NumberKind` and related functions from the API. (#864)
|
|
- Context arguments from `Aggregator.Checkpoint` and `Integrator.Process` as they were unused. (#803)
|
|
- `SpanID` is no longer included in parameters for sampling decision to match the OpenTelemetry specification. (#775)
|
|
|

|
|
|
|
### Changed
|
|
|
|
- Default to to use `AlwaysSampler` instead of `ProbabilitySampler` to match OpenTelemetry specification. (#506)
|
|
- Renamed `AlwaysSampleSampler` to `AlwaysOnSampler` in the trace API. (#511)
|
|
- Renamed `NeverSampleSampler` to `AlwaysOffSampler` in the trace API. (#511)
|
|

|
|
- Updated the trace `Sampler` interface conform to the OpenTelemetry specification. (#531)
|
|
- Rename metric API `Options` to `Config`. (#541)
|
|

|
|
- Correct error in zipkin module name. (#548)
|
|
- The jaeger trace exporter now supports `Resource`s. (#551)
|
|
- Metric SDK now supports `Resource`s.
|
|
The `WithResource` option was added to configure a `Resource` on creation and the `Resource` method was added to the metric `Descriptor` to return the associated `Resource`. (#552)
|
|
- Replace `ErrNoLastValue` and `ErrEmptyDataSet` by `ErrNoData` in the metric SDK. (#557)
|
|
- The stdout trace exporter now supports `Resource`s. (#558)

|
|
|
### Removed
|
|
|
|
- The vendor specific Stackdriver. It is now hosted on 3rd party vendor infrastructure. (#452)

|
|
- `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)

- 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)
|
|
|
|

|
|
This was corrected. (#333)
