This is not +an implementation of logging - it is an API. In fact it is two APIs with two +different sets of users. + +The `Logger` type is intended for application and library authors. It provides +a relatively small API which can be used everywhere you want to emit logs. It +defers the actual act of writing logs (to files, to stdout, or whatever) to the +`LogSink` interface. + +The `LogSink` interface is intended for logging library implementers. It is a +pure interface which can be implemented by logging frameworks to provide the actual logging +functionality. + +This decoupling allows application and library developers to write code in +terms of `logr.Logger` (which has very low dependency fan-out) while the +implementation of logging is managed "up stack" (e.g. in or near `main()`.) +Application developers can then switch out implementations as necessary. + +Many people assert that libraries should not be logging, and as such efforts +like this are pointless. Those people are welcome to convince the authors of +the tens-of-thousands of libraries that *DO* write logs that they are all +wrong. In the meantime, logr takes a more practical approach. + +## Typical usage + +Somewhere, early in an application's life, it will make a decision about which +logging library (implementation) it actually wants to use. Something like: + +``` + func main() { + // ... other setup code ... + + // Create the "root" logger. We have chosen the "logimpl" implementation, + // which takes some initial parameters and returns a logr.Logger. + logger := logimpl.New(param1, param2) + + // ... other setup code ... +``` + +Most apps will call into other libraries, create structures to govern the flow, +etc. The `logr.Logger` object can be passed to these other libraries, stored +in structs, or even used as a package-global variable, if needed. For example: + +``` + app := createTheAppObject(logger) + app.Run() +``` + +Outside of this early setup, no other packages need to know about the choice of +implementation. They write logs in terms of the `logr.Logger` that they +received: + +``` + type appObject struct { + // ... other fields ... + logger logr.Logger + // ... other fields ... + } + + func (app *appObject) Run() { + app.logger.Info("starting up", "timestamp", time.Now()) + + // ... app code ... +``` + +## Background + +If the Go standard library had defined an interface for logging, this project +probably would not be needed. Alas, here we are. + +### Inspiration + +Before you consider this package, please read [this blog post by the +inimitable Dave Cheney][warning-makes-no-sense]. We really appreciate what +he has to say, and it largely aligns with our own experiences. + +### Differences from Dave's ideas + +The main differences are: + +1. Dave basically proposes doing away with the notion of a logging API in favor +of `fmt.Printf()`. We disagree, especially when you consider things like output +locations, timestamps, file and line decorations, and structured logging. This +package restricts the logging API to just 2 types of logs: info and error. + +Info logs are things you want to tell the user which are not errors. Error +logs are, well, errors. If your code receives an `error` from a subordinate +function call and is logging that `error` *and not returning it*, use error +logs. + +2. Verbosity-levels on info logs. This gives developers a chance to indicate +arbitrary grades of importance for info logs, without assigning names with +semantic meaning such as "warning", "trace", and "debug." Superficially this +may feel very similar, but the primary difference is the lack of semantics. +Because verbosity is a numerical value, it's safe to assume that an app running +with higher verbosity means more (and less important) logs will be generated. + +## Implementations (non-exhaustive) + +There are implementations for the following logging libraries: + +- **a function** (can bridge to non-structured libraries): [funcr](https://github.com/go-logr/logr/tree/master/funcr) +- **a testing.T** (for use in Go tests, with JSON-like output): [testr](https://github.com/go-logr/logr/tree/master/testr) +- **github.com/google/glog**: [glogr](https://github.com/go-logr/glogr) +- **k8s.io/klog** (for Kubernetes): [klogr](https://git.k8s.io/klog/klogr) +- **a testing.T** (with klog-like text output): [ktesting](https://git.k8s.io/klog/ktesting) +- **go.uber.org/zap**: [zapr](https://github.com/go-logr/zapr) +- **log** (the Go standard library logger): [stdr](https://github.com/go-logr/stdr) +- **github.com/sirupsen/logrus**: [logrusr](https://github.com/bombsimon/logrusr) +- **github.com/wojas/genericr**: [genericr](https://github.com/wojas/genericr) (makes it easy to implement your own backend) +- **logfmt** (Heroku style [logging](https://www.brandur.org/logfmt)): [logfmtr](https://github.com/iand/logfmtr) +- **github.com/rs/zerolog**: [zerologr](https://github.com/go-logr/zerologr) +- **github.com/go-kit/log**: [gokitlogr](https://github.com/tonglil/gokitlogr) (also compatible with github.com/go-kit/kit/log since v0.12.0) +- **bytes.Buffer** (writing to a buffer): [bufrlogr](https://github.com/tonglil/buflogr) (useful for ensuring values were logged, like during testing) + +## FAQ + +### Conceptual + +#### Why structured logging? + +- **Structured logs are more easily queryable**: Since you've got + key-value pairs, it's much easier to query your structured logs for + particular values by filtering on the contents of a particular key -- + think searching request logs for error codes, Kubernetes reconcilers for + the name and namespace of the reconciled object, etc. + +- **Structured logging makes it easier to have cross-referenceable logs**: + Similarly to searchability, if you maintain conventions around your + keys, it becomes easy to gather all log lines related to a particular + concept. + +- **Structured logs allow better dimensions of filtering**: if you have + structure to your logs, you've got more precise control over how much + information is logged -- you might choose in a particular configuration + to log certain keys but not others, only log lines where a certain key + matches a certain value, etc., instead of just having v-levels and names + to key off of. + +- **Structured logs better represent structured data**: sometimes, the + data that you want to log is inherently structured (think tuple-link + objects.) Structured logs allow you to preserve that structure when + outputting. + +#### Why V-levels? + +**V-levels give operators an easy way to control the chattiness of log +operations**. V-levels provide a way for a given package to distinguish +the relative importance or verbosity of a given log message. Then, if +a particular logger or package is logging too many messages, the user +of the package can simply change the v-levels for that library. + +#### Why not named levels, like Info/Warning/Error? + +Read [Dave Cheney's post][warning-makes-no-sense]. Then read [Differences +from Dave's ideas](#differences-from-daves-ideas). + +#### Why not allow format strings, too? + +**Format strings negate many of the benefits of structured logs**: + +- They're not easily searchable without resorting to fuzzy searching, + regular expressions, etc. + +- They don't store structured data well, since contents are flattened into + a string. + +- They're not cross-referenceable. + +- They don't compress easily, since the message is not constant. + +(Unless you turn positional parameters into key-value pairs with numerical +keys, at which point you've gotten key-value logging with meaningless +keys.) + +### Practical + +#### Why key-value pairs, and not a map? + +Key-value pairs are *much* easier to optimize, especially around +allocations. Zap (a structured logger that inspired logr's interface) has +[performance measurements](https://github.com/uber-go/zap#performance) +that show this quite nicely. + +While the interface ends up being a little less obvious, you get +potentially better performance, plus avoid making users type +`map[string]string{}` every time they want to log. + +#### What if my V-levels differ between libraries? + +That's fine. Control your V-levels on a per-logger basis, and use the +`WithName` method to pass different loggers to different libraries. + +Generally, you should take care to ensure that you have relatively +consistent V-levels within a given logger, however, as this makes deciding +on what verbosity of logs to request easier. + +#### But I really want to use a format string! + +That's not actually a question. Assuming your question is "how do +I convert my mental model of logging with format strings to logging with +constant messages": + +1. Figure out what the error actually is, as you'd write in a TL;DR style, + and use that as a message. + +2. For every place you'd write a format specifier, look to the word before + it, and add that as a key value pair. + +For instance, consider the following examples (all taken from spots in the +Kubernetes codebase): + +- `klog.V(4).Infof("Client is returning errors: code %v, error %v", + responseCode, err)` becomes `logger.Error(err, "client returned an + error", "code", responseCode)` + +- `klog.V(4).Infof("Got a Retry-After %ds response for attempt %d to %v", + seconds, retries, url)` becomes `logger.V(4).Info("got a retry-after + response when requesting url", "attempt", retries, "after + seconds", seconds, "url", url)` + +If you *really* must use a format string, use it in a key's value, and +call `fmt.Sprintf` yourself. For instance: `log.Printf("unable to +reflect over type %T")` becomes `logger.Info("unable to reflect over +type", "type", fmt.Sprintf("%T"))`. In general though, the cases where +this is necessary should be few and far between. + +#### How do I choose my V-levels? + +This is basically the only hard constraint: increase V-levels to denote +more verbose or more debug-y logs. + +Otherwise, you can start out with `0` as "you always want to see this", +`1` as "common logging that you might *possibly* want to turn off", and +`10` as "I would like to performance-test your log collection stack." + +Then gradually choose levels in between as you need them, working your way +down from 10 (for debug and trace style logs) and up from 1 (for chattier +info-type logs.) + +#### How do I choose my keys? + +Keys are fairly flexible, and can hold more or less any string +value. For best compatibility with implementations and consistency +with existing code in other projects, there are a few conventions you +should consider. + +- Make your keys human-readable. +- Constant keys are generally a good idea. +- Be consistent across your codebase. +- Keys should naturally match parts of the message string. +- Use lower case for simple keys and + [lowerCamelCase](https://en.wiktionary.org/wiki/lowerCamelCase) for + more complex ones. Kubernetes is one example of a project that has + [adopted that + convention](https://github.com/kubernetes/community/blob/HEAD/contributors/devel/sig-instrumentation/migration-to-structured-logging.md#name-arguments). + +While key names are mostly unrestricted (and spaces are acceptable), +it's generally a good idea to stick to printable ascii characters, or at +least match the general character set of your log lines. + +#### Why should keys be constant values? + +The point of structured logging is to make later log processing easier. Your +keys are, effectively, the schema of each log message. If you use different +keys across instances of the same log line, you will make your structured logs +much harder to use. `Sprintf()` is for values, not for keys! + +#### Why is this not a pure interface? + +The Logger type is implemented as a struct in order to allow the Go compiler to +optimize things like high-V `Info` logs that are not triggered. Not all of +these implementations are implemented yet, but this structure was suggested as +a way to ensure they *can* be implemented. All of the real work is behind the +`LogSink` interface. + +[warning-makes-no-sense]: http://dave.cheney.net/2015/11/05/lets-talk-about-logging diff --git a/vendor/github.com/go-logr/logr/discard.go b/vendor/github.com/go-logr/logr/discard.go new file mode 100644 index 00000000000..9d92a38f1d7 --- /dev/null +++ b/vendor/github.com/go-logr/logr/discard.go @@ -0,0 +1,54 @@ +/* +Copyright 2020 The logr Authors. + +Licensed under the Apache License, Version 2.0 (the "License"); +you may not use this file except in compliance with the License. +You may obtain a copy of the License at + + http://www.apache.org/licenses/LICENSE-2.0 + +Unless required by applicable law or agreed to in writing, software +distributed under the License is distributed on an "AS IS" BASIS, +WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +See the License for the specific language governing permissions and +limitations under the License. +*/ + +package logr + +// Discard returns a Logger that discards all messages logged to it.

Logger is a concrete type with +// methods, which defers the actual logging to a LogSink interface. The main +// methods of Logger are Info() and Error(). Arguments to Info() and Error() +// are key/value pairs rather than printf-style formatted strings, emphasizing +// "structured logging". +// +// With Go's standard log package, we might write: +// log.Printf("setting target value %s", targetValue) +// +// With logr's structured logging, we'd write: +// logger.Info("setting target", "value", targetValue) +// +// Errors are much the same. Instead of: +// log.Printf("failed to open the pod bay door for user %s: %v", user, err) +// +// We'd write: +// logger.Error(err, "failed to open the pod bay door", "user", user) +// +// Info() and Error() are very similar, but they are separate methods so that +// LogSink implementations can choose to do things like attach additional +// information (such as stack traces) on calls to Error(). Error() messages are +// always logged, regardless of the current verbosity. If there is no error +// instance available, passing nil is valid. +// +// Verbosity +// +// Often we want to log information only when the application in "verbose +// mode". To write log lines that are more verbose, Logger has a V() method. +// The higher the V-level of a log line, the less critical it is considered. +// Log-lines with V-levels that are not enabled (as per the LogSink) will not +// be written. Level V(0) is the default, and logger.V(0).Info() has the same +// meaning as logger.Info(). Negative V-levels have the same meaning as V(0). +// Error messages do not have a verbosity level and are always logged. +// +// Where we might have written: +// if flVerbose >= 2 { +// log.Printf("an unusual thing happened") +// } +// +// We can write: +// logger.V(2).Info("an unusual thing happened") +// +// Logger Names +// +// Logger instances can have name strings so that all messages logged through +// that instance have additional context. For example, you might want to add +// a subsystem name: +// +// logger.WithName("compactor").Info("started", "time", time.Now()) +// +// The WithName() method returns a new Logger, which can be passed to +// constructors or other functions for further use. Repeated use of WithName() +// will accumulate name "segments". These name segments will be joined in some +// way by the LogSink implementation. It is strongly recommended that name +// segments contain simple identifiers (letters, digits, and hyphen), and do +// not contain characters that could muddle the log output or confuse the +// joining operation (e.g. whitespace, commas, periods, slashes, brackets, +// quotes, etc). +// +// Saved Values +// +// Logger instances can store any number of key/value pairs, which will be +// logged alongside all messages logged through that instance. For example, +// you might want to create a Logger instance per managed object: +// +// With the standard log package, we might write: +// log.Printf("decided to set field foo to value %q for object %s/%s", +// targetValue, object.Namespace, object.Name) +// +// With logr we'd write: +// // Elsewhere: set up the logger to log the object name. +// obj.logger = mainLogger.WithValues( +// "name", obj.name, "namespace", obj.namespace) +// +// // later on... +// obj.logger.Info("setting foo", "value", targetValue) +// +// Best Practices +// +// Logger has very few hard rules, with the goal that LogSink implementations +// might have a lot of freedom to differentiate. There are, however, some +// things to consider. +// +// The log message consists of a constant message attached to the log line. +// This should generally be a simple description of what's occurring, and should +// never be a format string. Variable information can then be attached using +// named values. +// +// Keys are arbitrary strings, but should generally be constant values. Values +// may be any Go value, but how the value is formatted is determined by the +// LogSink implementation. +// +// Logger instances are meant to be passed around by value. Code that receives +// such a value can call its methods without having to check whether the +// instance is ready for use. +// +// Calling methods with the null logger (Logger{}) as instance will crash +// because it has no LogSink. Therefore this null logger should never be passed +// around. For cases where passing a logger is optional, a pointer to Logger +// should be used. +// +// Key Naming Conventions +// +// Keys are not strictly required to conform to any specification or regex, but +// it is recommended that they: +// * be human-readable and meaningful (not auto-generated or simple ordinals) +// * be constant (not dependent on input data) +// * contain only printable characters +// * not contain whitespace or punctuation +// * use lower case for simple keys and lowerCamelCase for more complex ones +// +// These guidelines help ensure that log data is processed properly regardless +// of the log implementation. For example, log implementations will try to +// output JSON data or will store data for later database (e.g. SQL) queries. +// +// While users are generally free to use key names of their choice, it's +// generally best to avoid using the following keys, as they're frequently used +// by implementations: +// * "caller": the calling information (file/line) of a particular log line +// * "error": the underlying error value in the `Error` method +// * "level": the log level +// * "logger": the name of the associated logger +// * "msg": the log message +// * "stacktrace": the stack trace associated with a particular log line or +// error (often from the `Error` message) +// * "ts": the timestamp for a log line +// +// Implementations are encouraged to make use of these keys to represent the +// above concepts, when necessary (for example, in a pure-JSON output form, it +// would be necessary to represent at least message and timestamp as ordinary +// named values). +// +// Break Glass +// +// Implementations may choose to give callers access to the underlying +// logging implementation. The recommended pattern for this is: +// // Underlier exposes access to the underlying logging implementation. +// // Since callers only have a logr.Logger, they have to know which +// // implementation is in use, so this interface is less of an abstraction +// // and more of way to test type conversion. +// type Underlier interface { +// GetUnderlying() +// } +// +// Logger grants access to the sink to enable type assertions like this: +// func DoSomethingWithImpl(log logr.Logger) { +// if underlier, ok := log.GetSink()(impl.Underlier) { +// implLogger := underlier.GetUnderlying() +// ... +// } +// } +// +// Custom `With*` functions can be implemented by copying the complete +// Logger struct and replacing the sink in the copy: +// // WithFooBar changes the foobar parameter in the log sink and returns a +// // new logger with that modified sink.

(#2748) + +## [1.6.1] - 2022-03-28 + +### Fixed + +- The `go.opentelemetry.io/otel/schema/*` packages now use the correct schema URL for their `SchemaURL` constant. + Instead of using `"https://opentelemetry.io/schemas/v"` they now use the correct URL without a `v` prefix, `"https://opentelemetry.io/schemas/"`. (#2743, #2744) + +### Security + +- Upgrade `go.opentelemetry.io/proto/otlp` from `v0.12.0` to `v0.12.1`. + This includes an indirect upgrade of `github.com/grpc-ecosystem/grpc-gateway` which resolves [a vulnerability](https://nvd.nist.gov/vuln/detail/CVE-2019-11254) from `gopkg.in/yaml.v2` in version `v2.2.3`. (#2724, #2728) + +## [1.6.0/0.28.0] - 2022-03-23 + +### ⚠️ Notice ⚠️ + +This update is a breaking change of the unstable Metrics API. +Code instrumented with the `go.opentelemetry.io/otel/metric` will need to be modified. + +### Added + +- Add metrics exponential histogram support. + New mapping functions have been made available in `sdk/metric/aggregator/exponential/mapping` for other OpenTelemetry projects to take dependencies on. (#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 ommit 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`.

(#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.

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.

(#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.

(#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/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".SpanContextFromContex` 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.

(#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.

(#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) + +### Fixed + +- Upgrade OTLP exporter to opentelemetry-proto matching the opentelemetry-collector v0.4.0 release.

(#649) +- Batch metrics exported from the OTLP exporter based on `Resource` and labels. (#626) +- Add error wrapping to the prometheus exporter. (#631) +- Update the OTLP exporter batching of traces to use a unique `string` representation of an associated `Resource` as the batching key. (#623) +- Update OTLP `SpanData` transform to only include the `ParentSpanID` if one exists. (#614) +- Update `Resource` internal representation to uniquely and reliably identify resources. (#613) +- Check return value from `CheckpointSet.ForEach` in prometheus exporter. (#622) +- Ensure spans created by httptrace client tracer reflect operation structure. (#618) +- Create a new recorder rather than reuse when multiple observations in same epoch for asynchronous instruments. #610 +- The default port the OTLP exporter uses to connect to the OpenTelemetry collector is updated to match the one the collector listens on by default. (#611) + +## [0.4.2] - 2020-03-31 + +### Fixed + +- Fix `pre_release.sh` to update version in `sdk/opentelemetry.go`. (#607) +- Fix time conversion from internal to OTLP in OTLP exporter.

(#591) +- `LabelSet` from the metric API. + This is replaced by a `[]core.KeyValue` slice. (#595) +- `Labels` from the metric API's `Meter` interface. (#595) + +### Changed + +- The metric `export.Labels` became an interface which the SDK implements and the `export` package provides a simple, immutable implementation of this interface intended for testing purposes.

(#524) +- Context propagation in OpenTracing bridge in terms of OpenTelemetry context propagation. (#525) +- The `Resource` type was added to the SDK. (#528) +- The global API now supports a `Tracer` and `Meter` function as shortcuts to getting a global `*Provider` and calling these methods directly. (#538) +- The metric API now defines a generic `MeterImpl` interface to support general purpose `Meter` construction. + Additionally, `SyncImpl` and `AsyncImpl` are added to support general purpose instrument construction. (#560) +- A metric `Kind` is added to represent the `MeasureKind`, `ObserverKind`, and `CounterKind`. (#560) +- Scripts to better automate the release process. (#576) + +### 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) +- The `Status` field of the `Span` was changed to `StatusCode` to disambiguate with the added `StatusMessage`. (#524) +- Updated the trace `Sampler` interface conform to the OpenTelemetry specification. (#531) +- Rename metric API `Options` to `Config`. (#541) +- Rename metric `Counter` aggregator to be `Sum`. (#541) +- Unify metric options into `Option` from instrument specific options. (#541) +- The trace API's `TraceProvider` now support `Resource`s. (#545) +- Correct error in zipkin module name. (#548) +- The jaeger trace exporter now supports `Resource`s.

(#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.

(#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.

(#365) +- Lint make target now implements automatic fixes with `golangci-lint` before a second run to report the remaining issues. (#360) +- Drop `GO111MODULE` environment variable in Makefile as Go 1.13 is the project specified minimum version and this is environment variable is not needed for that version of Go.

(#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.

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/1A63zSWX0x2CyCK_LoNhmQC4rqhLpYXJzXbEPDUQ2n6w/edit#heading=h.9tngw7jdwd6b) +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. + +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`. + +### 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 to be **ready to merge** when: + +* It has received two approvals from Collaborators/Maintainers (at + different companies). This is not enforced through technical means + and a PR may be **ready to merge** with a single approval if the change + and its approach have been discussed and consensus reached. +* Feedback has been addressed. +* Any substantive changes to your PR will require that you clear any prior + Approval reviews, this includes changes resulting from other feedback. Unless + the approver explicitly stated that their approval will persist across + changes it should be assumed that the PR needs their review again. Other + project members (e.g. approvers, maintainers) can help with this if there are + any questions or if you forget to clear reviews. +* It has been open for review for at least one working day. This gives + people reasonable time to review. +* Trivial changes (typo, cosmetic, doc, etc.) do not have to wait for + one day and may be merged with a single Maintainer's approval. +* `CHANGELOG.md` has been updated to reflect what has been + added, changed, removed, or fixed. +* `README.md` has been updated if necessary. +* Urgent fix can take exception as long as it has been actively + communicated. + +Any Maintainer can merge the PR once it is **ready to merge**. + +## Design Choices + +As with other OpenTelemetry clients, opentelemetry-go follows the +[opentelemetry-specification](https://github.com/open-telemetry/opentelemetry-specification). + +It's especially valuable to read through the [library +guidelines](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/library-guidelines.md). + +### 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). + +## Documentation + +Each non-example Go Module should have its own `README.md` containing: + +- A pkg.go.dev badge which can be generated [here](https://pkg.go.dev/badge/). +- Brief description. +- Installation instructions (and requirements if applicable). +- Hyperlink to an example. Depending on the component the example can be: + - An `example_test.go` like [here](exporters/stdout/stdouttrace/example_test.go). + - A sample Go application with its own `README.md`, like [here](example/zipkin). +- Additional documentation sections such us: + - Configuration, + - Contributing, + - References. + +[Here](exporters/jaeger/README.md) is an example of a concise `README.md`. + +Moreover, it should be possible to navigate to any `README.md` from the +root `README.md`. + +## 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 therefor 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) + } + // Preform any validation here. + return config +} +``` + +If validation of the `config` options is also preformed 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 +doumentation are allowed to be extended with additional methods. + +> Warning: methods may be added to this interface in minor releases. + +Otherwise, stable interfaces MUST NOT be modified. + +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. + +## Approvers and Maintainers + +Approvers: + +- [Evan Torrie](https://github.com/evantorrie), Verizon Media +- [Josh MacDonald](https://github.com/jmacd), LightStep +- [Sam Xie](https://github.com/XSAM), Cisco/AppDynamics +- [David Ashpole](https://github.com/dashpole), Google +- [Gustavo Silva Paiva](https://github.com/paivagustavo), LightStep +- [Robert Pająk](https://github.com/pellared), Splunk +- [Chester Cheung](https://github.com/hanyuancheung), Tencent + +Maintainers: + +- [Aaron Clawson](https://github.com/MadVikingGod), LightStep +- [Anthony Mirabella](https://github.com/Aneurysm9), AWS +- [Tyler Yahn](https://github.com/MrAlias), Splunk + +### Become an Approver or a Maintainer + +See the [community membership document in OpenTelemetry community +repo](https://github.com/open-telemetry/community/blob/main/community-membership.md). diff --git a/vendor/go.opentelemetry.io/otel/LICENSE b/vendor/go.opentelemetry.io/otel/LICENSE new file mode 100644 index 00000000000..261eeb9e9f8 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/LICENSE @@ -0,0 +1,201 @@ + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

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 included [examples](./example/) 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 | Metrics | Traces | +| :-----------------------------------: | :-----: | :----: | +| [Jaeger](./exporters/jaeger/) | | ✓ | +| [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 00000000000..71e57625479 --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/RELEASING.md @@ -0,0 +1,122 @@ +# Release Process + +## Semantic Convention Generation + +New versions of the [OpenTelemetry specification] 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/attribute/doc.go b/vendor/go.opentelemetry.io/otel/attribute/doc.go new file mode 100644 index 00000000000..dafe7424dfb --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/attribute/doc.go @@ -0,0 +1,16 @@ +// Copyright The OpenTelemetry Authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +// Package attribute provides key and value attributes. +package attribute // import "go.opentelemetry.io/otel/attribute" diff --git a/vendor/go.opentelemetry.io/otel/attribute/encoder.go b/vendor/go.opentelemetry.io/otel/attribute/encoder.go new file mode 100644 index 00000000000..dae1d8f61fd --- /dev/null +++ b/vendor/go.opentelemetry.io/otel/attribute/encoder.go @@ -0,0 +1,146 @@ +// Copyright The OpenTelemetry Authors +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +package attribute // import "go.opentelemetry.io/otel/attribute" + +import ( + "bytes" + "sync" + "sync/atomic" +) + +type ( + // Encoder is a mechanism for serializing an attribute set into a specific + // string representation that supports caching, to avoid repeated + // serialization.
