+# Exponential Backoff [![GoDoc][godoc image]][godoc] [![Build Status][travis image]][travis] [![Coverage Status][coveralls image]][coveralls]
+
+This is a Go port of the exponential backoff algorithm from [Google's HTTP Client Library for Java][google-http-java-client].
+
+[Exponential backoff][exponential backoff wiki]
+is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
+in order to gradually find an acceptable rate.
+The retries exponentially increase and stop increasing when a certain threshold is met.
+
+## Usage

+Import path is `github.com/cenkalti/backoff/v4`. Please note the version part at the end.
+
+Use https://pkg.go.dev/github.com/cenkalti/backoff/v4 to view the documentation.
+
+## Contributing
+
+* I would like to keep this library as small as possible.
+* Please don't send a PR without opening an issue and discussing it first.
+* If proposed change is not a common use case, I will probably not accept it.

+ExponentialBackOff is a backoff implementation that increases the backoff
+period for each retry attempt using a randomization function that grows exponentially.
+
+NextBackOff() is calculated using the following formula:
+
+ randomized interval =
+ RetryInterval * (random value in range [1 - RandomizationFactor, 1 + RandomizationFactor])
+
+In other words NextBackOff() will range between the randomization factor
+percentage below and above the retry interval.
+
+For example, given the following parameters:
+
+ RetryInterval = 2
+ RandomizationFactor = 0.5
+ Multiplier = 2
+
+the actual backoff period used in the next retry attempt will range between 1 and 3 seconds,
+multiplied by the exponential, that is, between 2 and 6 seconds.
+
+Note: MaxInterval caps the RetryInterval and not the randomized interval.
+
+If the time elapsed since an ExponentialBackOff instance is created goes past the
+MaxElapsedTime, then the method NextBackOff() starts returning backoff.Stop.
+
+The elapsed time can be reset by calling Reset().
+
+Example: Given the following default arguments, for 10 tries the sequence will be,
+and assuming we go over the MaxElapsedTime on the 10th try:
+
+ Request # RetryInterval (seconds) Randomized Interval (seconds)
+
+ 1 0.5 [0.25, 0.75]
+ 2 0.75 [0.375, 1.125]

+ 7 5.692 [2.846, 8.538]
+ 8 8.538 [4.269, 12.807]
+ 9 12.807 [6.403, 19.210]

+# A minimal logging API for Go
+
+[](https://pkg.go.dev/github.com/go-logr/logr)
+
+logr offers an(other) opinion on how Go programs and libraries can do logging
+without becoming coupled to a particular logging implementation. 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.

+
+// This design derives from Dave Cheney's blog:
+// http://dave.cheney.net/2015/11/05/lets-talk-about-logging
+
+// Package logr defines a general-purpose logging API and abstract interfaces
+// to back that API. Packages in the Go ecosystem can depend on this package,
+// while callers can implement logging with whatever backend is appropriate.
+//
+// Usage
+//
+// Logging is done using a Logger instance. 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() <underlying-type>
+// }
+//
+// 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. It does nothing for loggers where
+// // the sink doesn't support that parameter.
+// func WithFoobar(log logr.Logger, foobar int) logr.Logger {
+// if foobarLogSink, ok := log.GetSink()(FoobarSink); ok {
+// log = log.WithSink(foobarLogSink.WithFooBar(foobar))
+// }
+// return log
+// }
+//
+// Don't use New to construct a new Logger with a LogSink retrieved from an
+// existing Logger. Source code attribution might not work correctly and
+// unexported fields in Logger get lost.
+//
+// Beware that the same LogSink instance may be shared by different logger
+// instances. Calling functions that modify the LogSink will affect all of

+# database/sql instrumentation for OpenTelemetry Go
+
+[database/sql OpenTelemetry instrumentation](https://uptrace.dev/opentelemetry/instrumentations/go-database-sql.html)
+records database queries (including `Tx` and `Stmt` queries) and reports `DBStats` metrics.
+
+## Installation
+
+```shell
+go get github.com/uptrace/opentelemetry-go-extra/otelsql
+```
+
+## Usage
+
+To instrument database/sql, you need to connect to a database using the API provided by otelsql:
+
+| sql | otelsql |
+| --------------------------- | ------------------------------- |
+| `sql.Open(driverName, dsn)` | `otelsql.Open(driverName, dsn)` |
+| `sql.OpenDB(connector)` | `otelsql.OpenDB(connector)` |
+
+```go
+import (
+ "github.com/uptrace/opentelemetry-go-extra/otelsql"
+ semconv "go.opentelemetry.io/otel/semconv/v1.10.0"
+)
+
+db, err := otelsql.Open("sqlite", "file::memory:?cache=shared",
+ otelsql.WithAttributes(semconv.DBSystemSqlite),
+ otelsql.WithDBName("mydb"))
+if err != nil {
+ panic(err)
+}
+
+// db is *sql.DB
+```
+
+And then use context-aware API to propagate the active span via
+[context](https://uptrace.dev/opentelemetry/go-tracing.html#context):
+
+```go
+var num int
+if err := db.QueryRowContext(ctx, "SELECT 42").Scan(&num); err != nil {
+ panic(err)
+}
+```
+
+See [example](/example/) for details.
+
+## Options
+
+Both [otelsql.Open](https://pkg.go.dev/github.com/uptrace/opentelemetry-go-extra/otelsql#Open) and
+[otelsql.OpenDB](https://pkg.go.dev/github.com/uptrace/opentelemetry-go-extra/otelsql#OpenDB) accept
+the same [options](https://pkg.go.dev/github.com/uptrace/opentelemetry-go-extra/otelsql#Option):
+
+- [WithAttributes](https://pkg.go.dev/github.com/uptrace/opentelemetry-go-extra/otelsql#WithAttributes)
+ configures attributes that are used to create a span.
+- [WithDBName](https://pkg.go.dev/github.com/uptrace/opentelemetry-go-extra/otelsql#WithDBName)
+ configures a `db.name` attribute.
+- [WithDBSystem](https://pkg.go.dev/github.com/uptrace/opentelemetry-go-extra/otelsql#WithDBSystem)
+ configures a `db.system` attribute. When possible, you should prefer using WithAttributes and
+ [semconv](https://pkg.go.dev/go.opentelemetry.io/otel/semconv/v1.10.0), for example,
+ `otelsql.WithAttributes(semconv.DBSystemSqlite)`.
+
+## sqlboiler
+
+You can use otelsql to instrument [sqlboiler](https://github.com/volatiletech/sqlboiler) ORM:
+
+```go
+import (
+ "github.com/uptrace/opentelemetry-go-extra/otelsql"
+ semconv "go.opentelemetry.io/otel/semconv/v1.10.0"
+)
+
+db, err := otelsql.Open("postgres", "dbname=fun user=abc",
+ otelsql.WithAttributes(semconv.DBSystemPostgreSQL))
+if err != nil {
+ return err
+}
+
+boil.SetDB(db)
+```
+
+## GORM 1
+
+You can use otelsql to instrument [GORM 1](https://v1.gorm.io/):
+
+```go
+import (
+ "github.com/jinzhu/gorm"
+ "github.com/uptrace/opentelemetry-go-extra/otelsql"
+ semconv "go.opentelemetry.io/otel/semconv/v1.10.0"
+)
+
+// gormOpen is like gorm.Open, but it uses otelsql to instrument the database.
+func gormOpen(driverName, dataSourceName string, opts ...otelsql.Option) (*gorm.DB, error) {
+ db, err := otelsql.Open(driverName, dataSourceName, opts...)
+ if err != nil {
+ return nil, err
+ }
+ return gorm.Open(driverName, db)
+}
+
+db, err := gormOpen("mysql", "user:password@/dbname",
+ otelsql.WithAttributes(semconv.DBSystemMySQL))
+if err != nil {
+ panic(err)
+}
+```
+
+To instrument GORM 2, use
+[otelgorm](https://github.com/uptrace/opentelemetry-go-extra/tree/main/otelgorm).
+
+## Alternatives
+
+- https://github.com/XSAM/otelsql - different driver registration and no metrics.
+- https://github.com/j2gg0s/otsql - like XSAM/otelsql but with Prometheus metrics.

+- Global error handler uses an atomic value instead of a mutex. (#3543)
+- Add `NewMetricProducer` to `go.opentelemetry.io/otel/bridge/opencensus`, which can be used to pass OpenCensus metrics to an OpenTelemetry Reader. (#3541)
+- Global logger uses an atomic value instead of a mutex. (#3545)
+- The `Shutdown` method of the `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` releases all computational resources when called the first time. (#3551)
+- The `Sampler` returned from `TraceIDRatioBased` `go.opentelemetry.io/otel/sdk/trace` now uses the rightmost bits for sampling decisions.
+ This fixes random sampling when using ID generators like `xray.IDGenerator` and increasing parity with other language implementations. (#3557)
+- Errors from `go.opentelemetry.io/otel/exporters/otlp/otlptrace` exporters are wrapped in erros identifying their signal name.

+ - The named `Callback` replaces the inline function parameter. (#3564)
+ - `Callback` is required to return an error. (#3576)
+ - `Callback` accepts the added `Observer` parameter added.
+ This new parameter is used by `Callback` implementations to observe values for asynchronous instruments instead of calling the `Observe` method of the instrument directly. (#3584)
+ - The slice of `instrument.Asynchronous` is now passed as a variadic argument. (#3587)
+- The exporter from `go.opentelemetry.io/otel/exporters/zipkin` is updated to use the `v1.16.0` version of semantic conventions.
+ This means it no longer uses the removed `net.peer.ip` or `http.host` attributes to determine the remote endpoint.
+ Instead it uses the `net.sock.peer` attributes. (#3581)
+- The `Min` and `Max` fields of the `HistogramDataPoint` in `go.opentelemetry.io/otel/sdk/metric/metricdata` are now defined with the added `Extrema` type instead of a `*float64`. (#3487)
+
+### Fixed
+
+- Asynchronous instruments that use sum aggregators and attribute filters correctly add values from equivalent attribute sets that have been filtered. (#3439, #3549)
+- The `RegisterCallback` method of the `Meter` from `go.opentelemetry.io/otel/sdk/metric` only registers a callback for instruments created by that meter.
+ Trying to register a callback with instruments from a different meter will result in an error being returned. (#3584)
+
+### Deprecated
+
+- The `NewMetricExporter` in `go.opentelemetry.io/otel/bridge/opencensus` is deprecated.
+ Use `NewMetricProducer` instead. (#3541)

+
+### Fixed
+
+- The `go.opentelemetry.io/otel/exporters/prometheus` exporter fixes duplicated `_total` suffixes. (#3369)
+- Remove comparable requirement for `Reader`s. (#3387)
+- Cumulative metrics from the OpenCensus bridge (`go.opentelemetry.io/otel/bridge/opencensus`) are defined as monotonic sums, instead of non-monotonic. (#3389)
+- Asynchronous counters (`Counter` and `UpDownCounter`) from the metric SDK now produce delta sums when configured with delta temporality. (#3398)

+ Use `Instrument`, `InstrumentKind`, `View`, and `NewView` in `go.opentelemetry.io/otel/sdk/metric` instead. (#3476)
+
+## [1.11.1/0.33.0] 2022-10-19
+
+### Added
+
+- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` registers with a Prometheus registerer on creation.
+ By default, it will register with the default Prometheus registerer.
+ A non-default registerer can be used by passing the `WithRegisterer` option. (#3239)

+
+### Fixed
+
+- The URL-encoded values from the `OTEL_RESOURCE_ATTRIBUTES` environment variable are decoded. (#2963)
+- The `baggage.NewMember` function decodes the `value` parameter instead of directly using it.
+ This fixes the implementation to be compliant with the W3C specification. (#3226)
+- Slice attributes of the `attribute` package are now comparable based on their value, not instance. (#3108 #3252)
+- The `Shutdown` and `ForceFlush` methods of the `"go.opentelemetry.io/otel/sdk/trace".TraceProvider` no longer return an error when no processor is registered. (#3268)
+- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` cumulatively sums histogram buckets. (#3281)
+- The sum of each histogram data point is now uniquely exported by the `go.opentelemetry.io/otel/exporters/otlpmetric` exporters. (#3284, #3293)
+- Recorded values for asynchronous counters (`Counter` and `UpDownCounter`) are interpreted as exact, not incremental, sum values by the metric SDK. (#3350, #3278)
+- `UpDownCounters` are now correctly output as Prometheus gauges in the `go.opentelemetry.io/otel/exporters/prometheus` exporter. (#3358)
+- The Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus` no longer describes the metrics it will send to Prometheus on startup.
+ Instead the exporter is defined as an "unchecked" collector for Prometheus.
+ This fixes the `reader is not registered` warning currently emitted on startup. (#3291 #3342)
+- The `go.opentelemetry.io/otel/exporters/prometheus` exporter now correctly adds `_total` suffixes to counter metrics. (#3360)
+- The `go.opentelemetry.io/otel/exporters/prometheus` exporter now adds a unit suffix to metric names.
+ This can be disabled using the `WithoutUnits()` option added to that package. (#3352)
+
+## [1.11.0/0.32.3] 2022-10-12

+- Return the same instrument every time a user makes the exact same instrument creation call. (#3229, #3251)
+- Return the existing instrument when a view transforms a creation call to match an existing instrument. (#3240, #3251)
+- Log a warning when a conflicting instrument (e.g. description, unit, data-type) is created instead of returning an error. (#3251)
+- The OpenCensus bridge no longer sends empty batches of metrics. (#3263)

+- The `LabelFilterSelector` interface from `go.opentelemetry.io/otel/sdk/metric/processor/reducer` is renamed to `AttributeFilterSelector`.
+ The method included in the renamed interface also changed from `LabelFilterFor` to `AttributeFilterFor`. (#2790)
+- The `Metadata.Labels` method from the `go.opentelemetry.io/otel/sdk/metric/export` package is renamed to `Metadata.Attributes`.
+ Consequentially, the `Record` type from the same package also has had the embedded method renamed. (#2790)

+
+### Added
+
+- The metrics global package was added back into several test files. (#2764)
+- The `Meter` function is added back to the `go.opentelemetry.io/otel/metric/global` package.
+ This function is a convenience function equivalent to calling `global.MeterProvider().Meter(...)`. (#2750)

+### Fixed
+
+- Allow non-comparable global `MeterProvider`, `TracerProvider`, and `TextMapPropagator` types to be set. (#2772, #2773)

+
+## [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<version>"` they now use the correct URL without a `v` prefix, `"https://opentelemetry.io/schemas/<version>"`. (#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_<signal>_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`. (#2095)
+
+### Deprecated
+
+- The `TextMapCarrier` and `TextMapPropagator` from the `go.opentelemetry.io/otel/oteltest` package and their associated creation functions (`TextMapCarrier`, `NewTextMapPropagator`) are deprecated. (#2114)
+- The `Harness` type from the `go.opentelemetry.io/otel/oteltest` package and its associated creation function, `NewHarness` are deprecated and will be removed in the next release. (#2123)
+- The `TraceStateFromKeyValues` function from the `go.opentelemetry.io/otel/oteltest` package is deprecated.
+ Use the `trace.ParseTraceState` function instead. (#2122)
+
+### Removed
+
+- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/jaeger`. (#2020)
+- Removed the deprecated package `go.opentelemetry.io/otel/exporters/trace/zipkin`. (#2020)
+- Removed the `"go.opentelemetry.io/otel/sdk/resource".WithBuiltinDetectors` function.
+ The explicit `With*` options for every built-in detector should be used instead. (#2026 #2097)
+- Removed the `WithMaxAttempts` and `WithBackoff` options from the `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` package.
+ The retry logic of the package has been updated to match the `otlptracegrpc` package and accordingly a `WithRetry` option is added that should be used instead. (#2095)
+- Removed `DroppedAttributeCount` field from `otel/trace.Link` struct. (#2118)
+
+### Fixed
+
+- When using WithNewRoot, don't use the parent context for making sampling decisions. (#2032)
+- `oteltest.Tracer` now creates a valid `SpanContext` when using `WithNewRoot`. (#2073)
+- OS type detector now sets the correct `dragonflybsd` value for DragonFly BSD. (#2092)
+- The OTel span status is correctly transformed into the OTLP status in the `go.opentelemetry.io/otel/exporters/otlp/otlptrace` package.
+ This fix will by default set the status to `Unset` if it is not explicitly set to `Ok` or `Error`. (#2099 #2102)
+- The `Inject` method for the `"go.opentelemetry.io/otel/propagation".TraceContext` type no longer injects empty `tracestate` values. (#2108)
+- Use `6831` as default Jaeger agent port instead of `6832`. (#2131)
+
+## [Experimental Metrics v0.22.0] - 2021-07-19
+
+### Added
+
+- Adds HTTP support for OTLP metrics exporter. (#2022)
+
+### Removed
+
+- Removed the deprecated package `go.opentelemetry.io/otel/exporters/metric/prometheus`. (#2020)
+
+## [1.0.0-RC1] / 0.21.0 - 2021-06-18
+
+With this release we are introducing a split in module versions. The tracing API and SDK are entering the `v1.0.0` Release Candidate phase with `v1.0.0-RC1`
+while the experimental metrics API and SDK continue with `v0.x` releases at `v0.21.0`. Modules at major version 1 or greater will not depend on modules
+with major version 0.
+
+### Added
+
+- Adds `otlpgrpc.WithRetry`option for configuring the retry policy for transient errors on the otlp/gRPC exporter. (#1832)
+ - The following status codes are defined as transient errors:
+ | gRPC Status Code | Description |
+ | ---------------- | ----------- |
+ | 1 | Cancelled |
+ | 4 | Deadline Exceeded |
+ | 8 | Resource Exhausted |
+ | 10 | Aborted |
+ | 10 | Out of Range |
+ | 14 | Unavailable |
+ | 15 | Data Loss |
+- Added `Status` type to the `go.opentelemetry.io/otel/sdk/trace` package to represent the status of a span. (#1874)
+- Added `SpanStub` type and its associated functions to the `go.opentelemetry.io/otel/sdk/trace/tracetest` package.
+ This type can be used as a testing replacement for the `SpanSnapshot` that was removed from the `go.opentelemetry.io/otel/sdk/trace` package. (#1873)
+- Adds support for scheme in `OTEL_EXPORTER_OTLP_ENDPOINT` according to the spec. (#1886)
+- Adds `trace.WithSchemaURL` option for configuring the tracer with a Schema URL. (#1889)
+- Added an example of using OpenTelemetry Go as a trace context forwarder. (#1912)
+- `ParseTraceState` is added to the `go.opentelemetry.io/otel/trace` package.
+ It can be used to decode a `TraceState` from a `tracestate` header string value. (#1937)
+- Added `Len` method to the `TraceState` type in the `go.opentelemetry.io/otel/trace` package.
+ This method returns the number of list-members the `TraceState` holds. (#1937)
+- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace` that defines a trace exporter that uses a `otlptrace.Client` to send data.
+ Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` implementing a gRPC `otlptrace.Client` and offers convenience functions, `NewExportPipeline` and `InstallNewPipeline`, to setup and install a `otlptrace.Exporter` in tracing .(#1922)
+- Added `Baggage`, `Member`, and `Property` types to the `go.opentelemetry.io/otel/baggage` package along with their related functions. (#1967)
+- Added `ContextWithBaggage`, `ContextWithoutBaggage`, and `FromContext` functions to the `go.opentelemetry.io/otel/baggage` package.
+ These functions replace the `Set`, `Value`, `ContextWithValue`, `ContextWithoutValue`, and `ContextWithEmpty` functions from that package and directly work with the new `Baggage` type. (#1967)
+- The `OTEL_SERVICE_NAME` environment variable is the preferred source for `service.name`, used by the environment resource detector if a service name is present both there and in `OTEL_RESOURCE_ATTRIBUTES`. (#1969)
+- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` implementing an HTTP `otlptrace.Client` and offers convenience functions, `NewExportPipeline` and `InstallNewPipeline`, to setup and install a `otlptrace.Exporter` in tracing. (#1963)
+- Changes `go.opentelemetry.io/otel/sdk/resource.NewWithAttributes` to require a schema URL. The old function is still available as `resource.NewSchemaless`. This is a breaking change. (#1938)
+- Several builtin resource detectors now correctly populate the schema URL. (#1938)
+- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlpmetric` that defines a metrics exporter that uses a `otlpmetric.Client` to send data.
+- Creates package `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` implementing a gRPC `otlpmetric.Client` and offers convenience functions, `New` and `NewUnstarted`, to create an `otlpmetric.Exporter`.(#1991)
+- Added `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` exporter. (#2005)
+- Added `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` exporter. (#2005)
+- Added a `TracerProvider()` method to the `"go.opentelemetry.io/otel/trace".Span` interface. This can be used to obtain a `TracerProvider` from a given span that utilizes the same trace processing pipeline. (#2009)
+
+### Changed
+
+- Make `NewSplitDriver` from `go.opentelemetry.io/otel/exporters/otlp` take variadic arguments instead of a `SplitConfig` item.
+ `NewSplitDriver` now automatically implements an internal `noopDriver` for `SplitConfig` fields that are not initialized. (#1798)
+- `resource.New()` now creates a Resource without builtin detectors. Previous behavior is now achieved by using `WithBuiltinDetectors` Option. (#1810)
+- Move the `Event` type from the `go.opentelemetry.io/otel` package to the `go.opentelemetry.io/otel/sdk/trace` package. (#1846)
+- CI builds validate against last two versions of Go, dropping 1.14 and adding 1.16. (#1865)
+- BatchSpanProcessor now report export failures when calling `ForceFlush()` method. (#1860)
+- `Set.Encoded(Encoder)` no longer caches the result of an encoding. (#1855)
+- Renamed `CloudZoneKey` to `CloudAvailabilityZoneKey` in Resource semantic conventions according to spec. (#1871)
+- The `StatusCode` and `StatusMessage` methods of the `ReadOnlySpan` interface and the `Span` produced by the `go.opentelemetry.io/otel/sdk/trace` package have been replaced with a single `Status` method.
+ This method returns the status of a span using the new `Status` type. (#1874)
+- Updated `ExportSpans` method of the`SpanExporter` interface type to accept `ReadOnlySpan`s instead of the removed `SpanSnapshot`.
+ This brings the export interface into compliance with the specification in that it now accepts an explicitly immutable type instead of just an implied one. (#1873)
+- Unembed `SpanContext` in `Link`. (#1877)
+- Generate Semantic conventions from the specification YAML. (#1891)
+- Spans created by the global `Tracer` obtained from `go.opentelemetry.io/otel`, prior to a functioning `TracerProvider` being set, now propagate the span context from their parent if one exists. (#1901)
+- The `"go.opentelemetry.io/otel".Tracer` function now accepts tracer options. (#1902)
+- Move the `go.opentelemetry.io/otel/unit` package to `go.opentelemetry.io/otel/metric/unit`. (#1903)
+- Changed `go.opentelemetry.io/otel/trace.TracerConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config.) (#1921)
+- Changed `go.opentelemetry.io/otel/trace.SpanConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#1921)
+- Changed `span.End()` now only accepts Options that are allowed at `End()`. (#1921)
+- Changed `go.opentelemetry.io/otel/metric.InstrumentConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#1921)
+- Changed `go.opentelemetry.io/otel/metric.MeterConfig` to conform to the [Contributing guidelines](CONTRIBUTING.md#config). (#1921)
+- Refactored option types according to the contribution style guide. (#1882)
+- Move the `go.opentelemetry.io/otel/trace.TraceStateFromKeyValues` function to the `go.opentelemetry.io/otel/oteltest` package.
+ This function is preserved for testing purposes where it may be useful to create a `TraceState` from `attribute.KeyValue`s, but it is not intended for production use.
+ The new `ParseTraceState` function should be used to create a `TraceState`. (#1931)
+- Updated `MarshalJSON` method of the `go.opentelemetry.io/otel/trace.TraceState` type to marshal the type into the string representation of the `TraceState`. (#1931)
+- The `TraceState.Delete` method from the `go.opentelemetry.io/otel/trace` package no longer returns an error in addition to a `TraceState`. (#1931)
+- Updated `Get` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a `string` instead of an `attribute.Key` type. (#1931)
+- Updated `Insert` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a pair of `string`s instead of an `attribute.KeyValue` type. (#1931)
+- Updated `Delete` method of the `TraceState` type from the `go.opentelemetry.io/otel/trace` package to accept a `string` instead of an `attribute.Key` type. (#1931)
+- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/stdout` package. (#1985)
+- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/metric/prometheus` package. (#1985)
+- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/trace/jaeger` package. (#1985)
+- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/trace/zipkin` package. (#1985)
+- Renamed `NewExporter` to `New` in the `go.opentelemetry.io/otel/exporters/otlp` package. (#1985)
+- Renamed `NewUnstartedExporter` to `NewUnstarted` in the `go.opentelemetry.io/otel/exporters/otlp` package. (#1985)
+- The `go.opentelemetry.io/otel/semconv` package has been moved to `go.opentelemetry.io/otel/semconv/v1.4.0` to allow for multiple [telemetry schema](https://github.com/open-telemetry/oteps/blob/main/text/0152-telemetry-schemas.md) versions to be used concurrently. (#1987)
+- Metrics test helpers in `go.opentelemetry.io/otel/oteltest` have been moved to `go.opentelemetry.io/otel/metric/metrictest`. (#1988)
+
+### Deprecated
+
+- The `go.opentelemetry.io/otel/exporters/metric/prometheus` is deprecated, use `go.opentelemetry.io/otel/exporters/prometheus` instead. (#1993)
+- The `go.opentelemetry.io/otel/exporters/trace/jaeger` is deprecated, use `go.opentelemetry.io/otel/exporters/jaeger` instead. (#1993)
+- The `go.opentelemetry.io/otel/exporters/trace/zipkin` is deprecated, use `go.opentelemetry.io/otel/exporters/zipkin` instead. (#1993)
+
+### Removed
+
+- Removed `resource.WithoutBuiltin()`. Use `resource.New()`. (#1810)
+- Unexported types `resource.FromEnv`, `resource.Host`, and `resource.TelemetrySDK`, Use the corresponding `With*()` to use individually. (#1810)
+- Removed the `Tracer` and `IsRecording` method from the `ReadOnlySpan` in the `go.opentelemetry.io/otel/sdk/trace`.
+ The `Tracer` method is not a required to be included in this interface and given the mutable nature of the tracer that is associated with a span, this method is not appropriate.
+ The `IsRecording` method returns if the span is recording or not.
+ A read-only span value does not need to know if updates to it will be recorded or not.
+ By definition, it cannot be updated so there is no point in communicating if an update is recorded. (#1873)
+- Removed the `SpanSnapshot` type from the `go.opentelemetry.io/otel/sdk/trace` package.
+ The use of this type has been replaced with the use of the explicitly immutable `ReadOnlySpan` type.
+ When a concrete representation of a read-only span is needed for testing, the newly added `SpanStub` in the `go.opentelemetry.io/otel/sdk/trace/tracetest` package should be used. (#1873)
+- Removed the `Tracer` method from the `Span` interface in the `go.opentelemetry.io/otel/trace` package.
+ Using the same tracer that created a span introduces the error where an instrumentation library's `Tracer` is used by other code instead of their own.
+ The `"go.opentelemetry.io/otel".Tracer` function or a `TracerProvider` should be used to acquire a library specific `Tracer` instead. (#1900)
+ - The `TracerProvider()` method on the `Span` interface may also be used to obtain a `TracerProvider` using the same trace processing pipeline. (#2009)
+- The `http.url` attribute generated by `HTTPClientAttributesFromHTTPRequest` will no longer include username or password information. (#1919)
+- Removed `IsEmpty` method of the `TraceState` type in the `go.opentelemetry.io/otel/trace` package in favor of using the added `TraceState.Len` method. (#1931)
+- Removed `Set`, `Value`, `ContextWithValue`, `ContextWithoutValue`, and `ContextWithEmpty` functions in the `go.opentelemetry.io/otel/baggage` package.
+ Handling of baggage is now done using the added `Baggage` type and related context functions (`ContextWithBaggage`, `ContextWithoutBaggage`, and `FromContext`) in that package. (#1967)
+- The `InstallNewPipeline` and `NewExportPipeline` creation functions in all the exporters (prometheus, otlp, stdout, jaeger, and zipkin) have been removed.
+ These functions were deemed premature attempts to provide convenience that did not achieve this aim. (#1985)
+- The `go.opentelemetry.io/otel/exporters/otlp` exporter has been removed. Use `go.opentelemetry.io/otel/exporters/otlp/otlptrace` instead. (#1990)
+- The `go.opentelemetry.io/otel/exporters/stdout` exporter has been removed. Use `go.opentelemetry.io/otel/exporters/stdout/stdouttrace` or `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` instead. (#2005)
+
+### Fixed
+
+- Only report errors from the `"go.opentelemetry.io/otel/sdk/resource".Environment` function when they are not `nil`. (#1850, #1851)
+- The `Shutdown` method of the simple `SpanProcessor` in the `go.opentelemetry.io/otel/sdk/trace` package now honors the context deadline or cancellation. (#1616, #1856)
+- BatchSpanProcessor now drops span batches that failed to be exported. (#1860)
+- Use `http://localhost:14268/api/traces` as default Jaeger collector endpoint instead of `http://localhost:14250`. (#1898)
+- Allow trailing and leading whitespace in the parsing of a `tracestate` header. (#1931)
+- Add logic to determine if the channel is closed to fix Jaeger exporter test panic with close closed channel. (#1870, #1973)
+- Avoid transport security when OTLP endpoint is a Unix socket. (#2001)
+
+### Security
+
+## [0.20.0] - 2021-04-23
+
+### Added
+
+- The OTLP exporter now has two new convenience functions, `NewExportPipeline` and `InstallNewPipeline`, setup and install the exporter in tracing and metrics pipelines. (#1373)
+- Adds semantic conventions for exceptions. (#1492)
+- Added Jaeger Environment variables: `OTEL_EXPORTER_JAEGER_AGENT_HOST`, `OTEL_EXPORTER_JAEGER_AGENT_PORT`
+ These environment variables can be used to override Jaeger agent hostname and port (#1752)
+- Option `ExportTimeout` was added to batch span processor. (#1755)
+- `trace.TraceFlags` is now a defined type over `byte` and `WithSampled(bool) TraceFlags` and `IsSampled() bool` methods have been added to it. (#1770)
+- The `Event` and `Link` struct types from the `go.opentelemetry.io/otel` package now include a `DroppedAttributeCount` field to record the number of attributes that were not recorded due to configured limits being reached. (#1771)
+- The Jaeger exporter now reports dropped attributes for a Span event in the exported log. (#1771)
+- Adds test to check BatchSpanProcessor ignores `OnEnd` and `ForceFlush` post `Shutdown`. (#1772)
+- Extract resource attributes from the `OTEL_RESOURCE_ATTRIBUTES` environment variable and merge them with the `resource.Default` resource as well as resources provided to the `TracerProvider` and metric `Controller`. (#1785)
+- Added `WithOSType` resource configuration option to set OS (Operating System) type resource attribute (`os.type`). (#1788)
+- Added `WithProcess*` resource configuration options to set Process resource attributes. (#1788)
+ - `process.pid`
+ - `process.executable.name`
+ - `process.executable.path`
+ - `process.command_args`
+ - `process.owner`
+ - `process.runtime.name`
+ - `process.runtime.version`
+ - `process.runtime.description`
+- Adds `k8s.node.name` and `k8s.node.uid` attribute keys to the `semconv` package. (#1789)
+- Added support for configuring OTLP/HTTP and OTLP/gRPC Endpoints, TLS Certificates, Headers, Compression and Timeout via Environment Variables. (#1758, #1769 and #1811)

+ - `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT`
+ - `OTEL_EXPORTER_OTLP_METRICS_ENDPOINT`
+ - `OTEL_EXPORTER_OTLP_HEADERS`

+ - `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

+- The `MetricKind` method of the `Descriptor` type in the `go.opentelemetry.io/otel/api/metric` package was renamed to `Descriptor.InstrumentKind`.
+ This matches the returned type and fixes misuse of the term metric. (#1240)
+- Move test harness from the `go.opentelemetry.io/otel/api/apitest` package into `go.opentelemetry.io/otel/oteltest`. (#1241)

+- The function signature of the Span `AddEvent` method in `go.opentelemetry.io/otel` is updated to no longer take an unused context and instead take a required name and a variable number of `EventOption`s. (#1254)
+- The function signature of the Span `RecordError` method in `go.opentelemetry.io/otel` is updated to no longer take an unused context and instead take a required error value and a variable number of `EventOption`s. (#1254)

+- The `AddEventWithTimestamp` method on the `Span` interface in `go.opentelemetry.io/otel` is removed due to its redundancy.
+ It is replaced by using the `AddEvent` method with a `WithTimestamp` option. (#1254)
+- The `MockSpan` and `MockTracer` types are removed from `go.opentelemetry.io/otel/oteltest`.
+ `Tracer` and `Span` from the same module should be used in their place instead. (#1306)

+- The `New` function from the `go.opentelemetry.io/otel/api/propagation` package was replaced with `NewCompositeTextMapPropagator` in the `go.opentelemetry.io/otel` package. (#1212)
+- The status codes of the `go.opentelemetry.io/otel/codes` package have been updated to match the latest OpenTelemetry specification.
+ They now are `Unset`, `Error`, and `Ok`.
+ They no longer track the gRPC codes. (#1214)
+- The `StatusCode` field of the `SpanData` struct in the `go.opentelemetry.io/otel/sdk/export/trace` package now uses the codes package from this package instead of the gRPC project. (#1214)
+- Move the `go.opentelemetry.io/otel/api/baggage` package into `go.opentelemetry.io/otel/baggage`. (#1217) (#1325)
+- A `Shutdown` method of `SpanProcessor` and all its implementations receives a context and returns an error. (#1264)
+
+### Fixed
+
+- Copies of data from arrays and slices passed to `go.opentelemetry.io/otel/label.ArrayValue()` are now used in the returned `Value` instead of using the mutable data itself. (#1226)
+
+### Removed
+
+- The `ExtractHTTP` and `InjectHTTP` functions from the `go.opentelemetry.io/otel/api/propagation` package were removed. (#1212)
+- The `Propagators` interface from the `go.opentelemetry.io/otel/api/propagation` package was removed to conform to the OpenTelemetry specification.
+ The explicit `TextMapPropagator` type can be used in its place as this is the `Propagator` type the specification defines. (#1212)
+- The `SetAttribute` method of the `Span` from the `go.opentelemetry.io/otel/api/trace` package was removed given its redundancy with the `SetAttributes` method. (#1216)
+- The internal implementation of Baggage storage is removed in favor of using the new Baggage API functionality. (#1217)
+- Remove duplicate hostname key `HostHostNameKey` in Resource semantic conventions. (#1219)
+- Nested array/slice support has been removed. (#1226)
+
+## [0.12.0] - 2020-09-24
+
+### Added
+
+- A `SpanConfigure` function in `go.opentelemetry.io/otel/api/trace` to create a new `SpanConfig` from `SpanOption`s. (#1108)
+- In the `go.opentelemetry.io/otel/api/trace` package, `NewTracerConfig` was added to construct new `TracerConfig`s.
+ This addition was made to conform with our project option conventions. (#1155)

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

+
+## [0.11.0] - 2020-08-24
+
+### Added
+
+- Support for exporting array-valued attributes via OTLP. (#992)
+- `Noop` and `InMemory` `SpanBatcher` implementations to help with testing integrations. (#994)
+- Support for filtering metric label sets. (#1047)
+- A dimensionality-reducing metric Processor. (#1057)
+- Integration tests for more OTel Collector Attribute types. (#1062)
+- A new `WithSpanProcessor` `ProviderOption` is added to the `go.opentelemetry.io/otel/sdk/trace` package to create a `Provider` and automatically register the `SpanProcessor`. (#1078)
+
+### Changed
+
+- Rename `sdk/metric/processor/test` to `sdk/metric/processor/processortest`. (#1049)
+- Rename `sdk/metric/controller/test` to `sdk/metric/controller/controllertest`. (#1049)
+- Rename `api/testharness` to `api/apitest`. (#1049)
+- Rename `api/trace/testtrace` to `api/trace/tracetest`. (#1049)
+- Change Metric Processor to merge multiple observations. (#1024)
+- The `go.opentelemetry.io/otel/bridge/opentracing` bridge package has been made into its own module.
+ This removes the package dependencies of this bridge from the rest of the OpenTelemetry based project. (#1038)
+- Renamed `go.opentelemetry.io/otel/api/standard` package to `go.opentelemetry.io/otel/semconv` to avoid the ambiguous and generic name `standard` and better describe the package as containing OpenTelemetry semantic conventions. (#1016)
+- The environment variable used for resource detection has been changed from `OTEL_RESOURCE_LABELS` to `OTEL_RESOURCE_ATTRIBUTES` (#1042)
+- Replace `WithSyncer` with `WithBatcher` in examples. (#1044)
+- Replace the `google.golang.org/grpc/codes` dependency in the API with an equivalent `go.opentelemetry.io/otel/codes` package. (#1046)
+- Merge the `go.opentelemetry.io/otel/api/label` and `go.opentelemetry.io/otel/api/kv` into the new `go.opentelemetry.io/otel/label` package. (#1060)
+- Unify Callback Function Naming.
+ Rename `*Callback` with `*Func`. (#1061)
+- CI builds validate against last two versions of Go, dropping 1.13 and adding 1.15. (#1064)
+- The `go.opentelemetry.io/otel/sdk/export/trace` interfaces `SpanSyncer` and `SpanBatcher` have been replaced with a specification compliant `Exporter` interface.
+ This interface still supports the export of `SpanData`, but only as a slice.
+ Implementation are also required now to return any error from `ExportSpans` if one occurs as well as implement a `Shutdown` method for exporter clean-up. (#1078)
+- The `go.opentelemetry.io/otel/sdk/trace` `NewBatchSpanProcessor` function no longer returns an error.
+ If a `nil` exporter is passed as an argument to this function, instead of it returning an error, it now returns a `BatchSpanProcessor` that handles the export of `SpanData` by not taking any action. (#1078)
+- The `go.opentelemetry.io/otel/sdk/trace` `NewProvider` function to create a `Provider` no longer returns an error, instead only a `*Provider`.
+ This change is related to `NewBatchSpanProcessor` not returning an error which was the only error this function would return. (#1078)
+
+### Removed
+
+- Duplicate, unused API sampler interface. (#999)
+ Use the [`Sampler` interface](https://github.com/open-telemetry/opentelemetry-go/blob/v0.11.0/sdk/trace/sampling.go) provided by the SDK instead.
+- The `grpctrace` instrumentation was moved to the `go.opentelemetry.io/contrib` repository and out of this repository.
+ This move includes moving the `grpc` example to the `go.opentelemetry.io/contrib` as well. (#1027)
+- The `WithSpan` method of the `Tracer` interface.
+ The functionality this method provided was limited compared to what a user can provide themselves.
+ It was removed with the understanding that if there is sufficient user need it can be added back based on actual user usage. (#1043)
+- The `RegisterSpanProcessor` and `UnregisterSpanProcessor` functions.
+ These were holdovers from an approach prior to the TracerProvider design. They were not used anymore. (#1077)
+- The `oterror` package. (#1026)
+- The `othttp` and `httptrace` instrumentations were moved to `go.opentelemetry.io/contrib`. (#1032)
+
+### Fixed
+
+- The `semconv.HTTPServerMetricAttributesFromHTTPRequest()` function no longer generates the high-cardinality `http.request.content.length` label. (#1031)
+- Correct instrumentation version tag in Jaeger exporter. (#1037)
+- The SDK span will now set an error event if the `End` method is called during a panic (i.e. it was deferred). (#1043)
+- Move internally generated protobuf code from the `go.opentelemetry.io/otel` to the OTLP exporter to reduce dependency overhead. (#1050)
+- The `otel-collector` example referenced outdated collector processors. (#1006)
+
+## [0.10.0] - 2020-07-29
+
+This release migrates the default OpenTelemetry SDK into its own Go module, decoupling the SDK from the API and reducing dependencies for instrumentation packages.
+
+### Added
+
+- The Zipkin exporter now has `NewExportPipeline` and `InstallNewPipeline` constructor functions to match the common pattern.
+ These function build a new exporter with default SDK options and register the exporter with the `global` package respectively. (#944)
+- Add propagator option for gRPC instrumentation. (#986)
+- The `testtrace` package now tracks the `trace.SpanKind` for each span. (#987)
+
+### Changed
+
+- Replace the `RegisterGlobal` `Option` in the Jaeger exporter with an `InstallNewPipeline` constructor function.
+ This matches the other exporter constructor patterns and will register a new exporter after building it with default configuration. (#944)
+- The trace (`go.opentelemetry.io/otel/exporters/trace/stdout`) and metric (`go.opentelemetry.io/otel/exporters/metric/stdout`) `stdout` exporters are now merged into a single exporter at `go.opentelemetry.io/otel/exporters/stdout`.
+ This new exporter was made into its own Go module to follow the pattern of all exporters and decouple it from the `go.opentelemetry.io/otel` module. (#956, #963)
+- Move the `go.opentelemetry.io/otel/exporters/test` test package to `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#962)
+- The `go.opentelemetry.io/otel/api/kv/value` package was merged into the parent `go.opentelemetry.io/otel/api/kv` package. (#968)
+ - `value.Bool` was replaced with `kv.BoolValue`.
+ - `value.Int64` was replaced with `kv.Int64Value`.
+ - `value.Uint64` was replaced with `kv.Uint64Value`.
+ - `value.Float64` was replaced with `kv.Float64Value`.
+ - `value.Int32` was replaced with `kv.Int32Value`.
+ - `value.Uint32` was replaced with `kv.Uint32Value`.
+ - `value.Float32` was replaced with `kv.Float32Value`.
+ - `value.String` was replaced with `kv.StringValue`.
+ - `value.Int` was replaced with `kv.IntValue`.
+ - `value.Uint` was replaced with `kv.UintValue`.
+ - `value.Array` was replaced with `kv.ArrayValue`.
+- Rename `Infer` to `Any` in the `go.opentelemetry.io/otel/api/kv` package. (#972)
+- Change `othttp` to use the `httpsnoop` package to wrap the `ResponseWriter` so that optional interfaces (`http.Hijacker`, `http.Flusher`, etc.) that are implemented by the original `ResponseWriter`are also implemented by the wrapped `ResponseWriter`. (#979)
+- Rename `go.opentelemetry.io/otel/sdk/metric/aggregator/test` package to `go.opentelemetry.io/otel/sdk/metric/aggregator/aggregatortest`. (#980)
+- Make the SDK into its own Go module called `go.opentelemetry.io/otel/sdk`. (#985)
+- Changed the default trace `Sampler` from `AlwaysOn` to `ParentOrElse(AlwaysOn)`. (#989)
+
+### Removed
+
+- The `IndexedAttribute` function from the `go.opentelemetry.io/otel/api/label` package was removed in favor of `IndexedLabel` which it was synonymous with. (#970)
+
+### Fixed
+
+- Bump github.com/golangci/golangci-lint from 1.28.3 to 1.29.0 in /tools. (#953)
+- Bump github.com/google/go-cmp from 0.5.0 to 0.5.1. (#957)
+- Use `global.Handle` for span export errors in the OTLP exporter. (#946)
+- Correct Go language formatting in the README documentation. (#961)
+- Remove default SDK dependencies from the `go.opentelemetry.io/otel/api` package. (#977)
+- Remove default SDK dependencies from the `go.opentelemetry.io/otel/instrumentation` package. (#983)
+- Move documented examples for `go.opentelemetry.io/otel/instrumentation/grpctrace` interceptors into Go example tests. (#984)
+
+## [0.9.0] - 2020-07-20
+
+### Added
+
+- A new Resource Detector interface is included to allow resources to be automatically detected and included. (#939)
+- A Detector to automatically detect resources from an environment variable. (#939)
+- Github action to generate protobuf Go bindings locally in `internal/opentelemetry-proto-gen`. (#938)
+- OTLP .proto files from `open-telemetry/opentelemetry-proto` imported as a git submodule under `internal/opentelemetry-proto`.
+ References to `github.com/open-telemetry/opentelemetry-proto` changed to `go.opentelemetry.io/otel/internal/opentelemetry-proto-gen`. (#942)
+
+### Changed
+
+- Non-nil value `struct`s for key-value pairs will be marshalled using JSON rather than `Sprintf`. (#948)
+
+### Removed
+
+- Removed dependency on `github.com/open-telemetry/opentelemetry-collector`. (#943)
+
+## [0.8.0] - 2020-07-09
+
+### Added
+
+- The `B3Encoding` type to represent the B3 encoding(s) the B3 propagator can inject.
+ A value for HTTP supported encodings (Multiple Header: `MultipleHeader`, Single Header: `SingleHeader`) are included. (#882)
+- The `FlagsDeferred` trace flag to indicate if the trace sampling decision has been deferred. (#882)
+- The `FlagsDebug` trace flag to indicate if the trace is a debug trace. (#882)
+- Add `peer.service` semantic attribute. (#898)
+- Add database-specific semantic attributes. (#899)
+- Add semantic convention for `faas.coldstart` and `container.id`. (#909)
+- Add http content size semantic conventions. (#905)
+- Include `http.request_content_length` in HTTP request basic attributes. (#905)
+- Add semantic conventions for operating system process resource attribute keys. (#919)
+- The Jaeger exporter now has a `WithBatchMaxCount` option to specify the maximum number of spans sent in a batch. (#931)
+
+### Changed
+
+- Update `CONTRIBUTING.md` to ask for updates to `CHANGELOG.md` with each pull request. (#879)
+- Use lowercase header names for B3 Multiple Headers. (#881)
+- The B3 propagator `SingleHeader` field has been replaced with `InjectEncoding`.
+ This new field can be set to combinations of the `B3Encoding` bitmasks and will inject trace information in these encodings.
+ If no encoding is set, the propagator will default to `MultipleHeader` encoding. (#882)
+- The B3 propagator now extracts from either HTTP encoding of B3 (Single Header or Multiple Header) based on what is contained in the header.
+ Preference is given to Single Header encoding with Multiple Header being the fallback if Single Header is not found or is invalid.
+ This behavior change is made to dynamically support all correctly encoded traces received instead of having to guess the expected encoding prior to receiving. (#882)
+- Extend semantic conventions for RPC. (#900)
+- To match constant naming conventions in the `api/standard` package, the `FaaS*` key names are appended with a suffix of `Key`. (#920)
+ - `"api/standard".FaaSName` -> `FaaSNameKey`
+ - `"api/standard".FaaSID` -> `FaaSIDKey`
+ - `"api/standard".FaaSVersion` -> `FaaSVersionKey`
+ - `"api/standard".FaaSInstance` -> `FaaSInstanceKey`
+
+### Removed
+
+- The `FlagsUnused` trace flag is removed.
+ The purpose of this flag was to act as the inverse of `FlagsSampled`, the inverse of `FlagsSampled` is used instead. (#882)
+- The B3 header constants (`B3SingleHeader`, `B3DebugFlagHeader`, `B3TraceIDHeader`, `B3SpanIDHeader`, `B3SampledHeader`, `B3ParentSpanIDHeader`) are removed.
+ If B3 header keys are needed [the authoritative OpenZipkin package constants](https://pkg.go.dev/github.com/openzipkin/zipkin-go@v0.2.2/propagation/b3?tab=doc#pkg-constants) should be used instead. (#882)
+
+### Fixed
+
+- The B3 Single Header name is now correctly `b3` instead of the previous `X-B3`. (#881)
+- The B3 propagator now correctly supports sampling only values (`b3: 0`, `b3: 1`, or `b3: d`) for a Single B3 Header. (#882)
+- The B3 propagator now propagates the debug flag.
+ This removes the behavior of changing the debug flag into a set sampling bit.
+ Instead, this now follow the B3 specification and omits the `X-B3-Sampling` header. (#882)
+- The B3 propagator now tracks "unset" sampling state (meaning "defer the decision") and does not set the `X-B3-Sampling` header when injecting. (#882)
+- Bump github.com/itchyny/gojq from 0.10.3 to 0.10.4 in /tools. (#883)
+- Bump github.com/opentracing/opentracing-go from v1.1.1-0.20190913142402-a7454ce5950e to v1.2.0. (#885)
+- The tracing time conversion for OTLP spans is now correctly set to `UnixNano`. (#896)
+- Ensure span status is not set to `Unknown` when no HTTP status code is provided as it is assumed to be `200 OK`. (#908)
+- Ensure `httptrace.clientTracer` closes `http.headers` span. (#912)
+- Prometheus exporter will not apply stale updates or forget inactive metrics. (#903)
+- Add test for api.standard `HTTPClientAttributesFromHTTPRequest`. (#905)
+- Bump github.com/golangci/golangci-lint from 1.27.0 to 1.28.1 in /tools. (#901, #913)
+- Update otel-colector example to use the v0.5.0 collector. (#915)
+- The `grpctrace` instrumentation uses a span name conforming to the OpenTelemetry semantic conventions (does not contain a leading slash (`/`)). (#922)
+- The `grpctrace` instrumentation includes an `rpc.method` attribute now set to the gRPC method name. (#900, #922)
+- The `grpctrace` instrumentation `rpc.service` attribute now contains the package name if one exists.
+ This is in accordance with OpenTelemetry semantic conventions. (#922)
+- Correlation Context extractor will no longer insert an empty map into the returned context when no valid values are extracted. (#923)
+- Bump google.golang.org/api from 0.28.0 to 0.29.0 in /exporters/trace/jaeger. (#925)
+- Bump github.com/itchyny/gojq from 0.10.4 to 0.11.0 in /tools. (#926)

+## [0.7.0] - 2020-06-26
+
+This release implements the v0.5.0 version of the OpenTelemetry specification.
+
+### Added
+
+- The othttp instrumentation now includes default metrics. (#861)
+- This CHANGELOG file to track all changes in the project going forward.
+- Support for array type attributes. (#798)
+- Apply transitive dependabot go.mod dependency updates as part of a new automatic Github workflow. (#844)
+- Timestamps are now passed to exporters for each export. (#835)
+- Add new `Accumulation` type to metric SDK to transport telemetry from `Accumulator`s to `Processor`s.
+ This replaces the prior `Record` `struct` use for this purpose. (#835)
+- New dependabot integration to automate package upgrades. (#814)
+- `Meter` and `Tracer` implementations accept instrumentation version version as an optional argument.
+ This instrumentation version is passed on to exporters. (#811) (#805) (#802)
+- The OTLP exporter includes the instrumentation version in telemetry it exports. (#811)
+- Environment variables for Jaeger exporter are supported. (#796)
+- New `aggregation.Kind` in the export metric API. (#808)
+- New example that uses OTLP and the collector. (#790)
+- Handle errors in the span `SetName` during span initialization. (#791)
+- Default service config to enable retries for retry-able failed requests in the OTLP exporter and an option to override this default. (#777)
+- New `go.opentelemetry.io/otel/api/oterror` package to uniformly support error handling and definitions for the project. (#778)
+- New `global` default implementation of the `go.opentelemetry.io/otel/api/oterror.Handler` interface to be used to handle errors prior to an user defined `Handler`.
+ There is also functionality for the user to register their `Handler` as well as a convenience function `Handle` to handle an error with this global `Handler`(#778)
+- Options to specify propagators for httptrace and grpctrace instrumentation. (#784)
+- The required `application/json` header for the Zipkin exporter is included in all exports. (#774)
+- Integrate HTTP semantics helpers from the contrib repository into the `api/standard` package. #769
+
+### Changed
+
+- Rename `Integrator` to `Processor` in the metric SDK. (#863)
+- Rename `AggregationSelector` to `AggregatorSelector`. (#859)
+- Rename `SynchronizedCopy` to `SynchronizedMove`. (#858)
+- Rename `simple` integrator to `basic` integrator. (#857)
+- Merge otlp collector examples. (#841)
+- Change the metric SDK to support cumulative, delta, and pass-through exporters directly.
+ With these changes, cumulative and delta specific exporters are able to request the correct kind of aggregation from the SDK. (#840)
+- The `Aggregator.Checkpoint` API is renamed to `SynchronizedCopy` and adds an argument, a different `Aggregator` into which the copy is stored. (#812)
+- The `export.Aggregator` contract is that `Update()` and `SynchronizedCopy()` are synchronized with each other.
+ All the aggregation interfaces (`Sum`, `LastValue`, ...) are not meant to be synchronized, as the caller is expected to synchronize aggregators at a higher level after the `Accumulator`.
+ Some of the `Aggregators` used unnecessary locking and that has been cleaned up. (#812)
+- Use of `metric.Number` was replaced by `int64` now that we use `sync.Mutex` in the `MinMaxSumCount` and `Histogram` `Aggregators`. (#812)
+- Replace `AlwaysParentSample` with `ParentSample(fallback)` to match the OpenTelemetry v0.5.0 specification. (#810)
+- Rename `sdk/export/metric/aggregator` to `sdk/export/metric/aggregation`. #808
+- Send configured headers with every request in the OTLP exporter, instead of just on connection creation. (#806)
+- Update error handling for any one off error handlers, replacing, instead, with the `global.Handle` function. (#791)
+- Rename `plugin` directory to `instrumentation` to match the OpenTelemetry specification. (#779)
+- Makes the argument order to Histogram and DDSketch `New()` consistent. (#781)
+
+### Removed
+
+- `Uint64NumberKind` and related functions from the API. (#864)

+- Context 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)

+
+### Removed
+
+- The vendor specific Stackdriver. It is now hosted on 3rd party vendor infrastructure. (#452)
+- The `Unregister` method for metric observers as it is not in the OpenTelemetry specification. (#560)
+- `GetDescriptor` from the metric SDK. (#575)
+- The `Gauge` instrument from the metric API. (#537)
+
+### Fixed
+
+- Make histogram aggregator checkpoint consistent. (#438)
+- Update README with import instructions and how to build and test. (#505)
+- The default label encoding was updated to be unique. (#508)
+- Use `NewRoot` in the othttp plugin for public endpoints. (#513)
+- Fix data race in `BatchedSpanProcessor`. (#518)
+- Skip test-386 for Mac OS 10.15.x (Catalina and upwards). #521
+- Use a variable-size array to represent ordered labels in maps. (#523)

+
+## [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)

+- `Propagators` interface in the propagation API to contain the set of injectors and extractors for all supported carrier formats. (#467)
+- `HTTPPropagator` interface in the propagation API to inject and extract from an `HTTPSupplier.` (#467)

+- `DefaultPropagator` function and have it return `trace.TraceContext` as the default context propagator. (#456)
+- `AlwaysParentSample` sampler to the trace API. (#455)
+- `WithNewRoot` option function to the trace API to specify the created span should be considered a root span. (#451)
+
+### Changed
+
+- Renamed `WithMap` to `ContextWithMap` in the correlation package. (#481)
+- Renamed `FromContext` to `MapFromContext` in the correlation package. (#481)
+- Move correlation context propagation to correlation package. (#479)
+- Do not default to putting remote span context into links. (#480)
+- `Tracer.WithSpan` updated to accept `StartOptions`. (#472)
+- Renamed `MetricKind` to `Kind` to not stutter in the type usage. (#432)
+- Renamed the `export` package to `metric` to match directory structure. (#432)
+- Rename the `api/distributedcontext` package to `api/correlation`. (#444)
+- Rename the `api/propagators` package to `api/propagation`. (#444)
+- Move the propagators from the `propagators` package into the `trace` API package. (#444)

+
+### Removed

+# Contributing to opentelemetry-go
+
+The Go special interest group (SIG) meets regularly. See the
+OpenTelemetry
+[community](https://github.com/open-telemetry/community#golang-sdk)
+repo for information on this and other language SIGs.
+
+See the [public meeting
+notes](https://docs.google.com/document/d/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 <YOUR_FORK> git@github.com:<YOUR_GITHUB_USERNAME>/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 <YOUR_BRANCH_NAME>
+# edit files
+# update changelog
+make precommit
+git add -p
+git commit
+git push <YOUR_FORK> <YOUR_BRANCH_NAME>
+```
+
+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.

+
+OpenTelemetry-Go is the [Go](https://golang.org/) implementation of [OpenTelemetry](https://opentelemetry.io/).
+It provides a set of APIs to directly measure performance and behavior of your software and send this data to observability platforms.
+
+## Project Status
+
+| Signal | Status | Project |
+| ------- | ---------- | ------- |
+| Traces | Stable | N/A |
+| Metrics | Alpha | N/A |
+| Logs | Frozen [1] | N/A |
+
+- [1]: The Logs signal development is halted for this project while we develop both Traces and Metrics.
+ No Logs Pull Requests are currently being accepted.
+
+Progress and status specific to this repository is tracked in our local
+[project boards](https://github.com/open-telemetry/opentelemetry-go/projects)
+and
+[milestones](https://github.com/open-telemetry/opentelemetry-go/milestones).
+
+Project versioning information and stability guarantees can be found in the
+[versioning documentation](./VERSIONING.md).
+
+### Compatibility
+
+OpenTelemetry-Go ensures compatibility with the current supported versions of
+the [Go language](https://golang.org/doc/devel/release#policy):
+
+> Each major Go release is supported until there are two newer major releases.
+> For example, Go 1.5 was supported until the Go 1.7 release, and Go 1.6 was supported until the Go 1.8 release.
+
+For versions of Go that are no longer supported upstream, opentelemetry-go will
+stop ensuring compatibility with these versions in the following manner:
+
+- A minor release of opentelemetry-go will be made to add support for the new
+ supported release of Go.
+- The following minor release of opentelemetry-go will remove compatibility
+ testing for the oldest (now archived upstream) version of Go. This, and
+ future, releases of opentelemetry-go may include features only supported by
+ the currently supported versions of Go.
+
+Currently, this project supports the following environments.
+
+| OS | Go Version | Architecture |
+| ------- | ---------- | ------------ |
+| Ubuntu | 1.20 | amd64 |
+| Ubuntu | 1.19 | amd64 |
+| Ubuntu | 1.18 | amd64 |
+| Ubuntu | 1.20 | 386 |
+| Ubuntu | 1.19 | 386 |
+| Ubuntu | 1.18 | 386 |
+| MacOS | 1.20 | amd64 |
+| MacOS | 1.19 | amd64 |
+| MacOS | 1.18 | amd64 |
+| Windows | 1.20 | amd64 |

+| Windows | 1.18 | amd64 |
+| Windows | 1.20 | 386 |
+| Windows | 1.19 | 386 |
+| Windows | 1.18 | 386 |
+
+While this project should work for other systems, no compatibility guarantees
+are made for those systems currently.
+
+## Getting Started
+
+You can find a getting started guide on [opentelemetry.io](https://opentelemetry.io/docs/go/getting-started/).
+
+OpenTelemetry's goal is to provide a single set of APIs to capture distributed
+traces and metrics from your application and send them to an observability
+platform. 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/) | | ✓ |

+# 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. Checkout a local copy of the [OpenTelemetry specification] to the desired release tag.
+2. Pull the latest `otel/semconvgen` image: `docker pull otel/semconvgen:latest`
+3. Run the `make semconv-generate ...` target from this repository.
+
+For example,
+
+```sh
+export TAG="v1.13.0" # Change to the release version you are generating.
+export OTEL_SPEC_REPO="/absolute/path/to/opentelemetry-specification"
+git -C "$OTEL_SPEC_REPO" checkout "tags/$TAG" -b "$TAG"
+docker pull otel/semconvgen:latest
+make semconv-generate # Uses the exported TAG and OTEL_SPEC_REPO.
+```
+
+This should create a new sub-package of [`semconv`](./semconv).
+Ensure things look correct before submitting a pull request to include the addition.
+
+**Note**, the generation code was changed to generate versions >= 1.13.
+To generate versions prior to this, checkout the old release of this repository (i.e. [2fe8861](https://github.com/open-telemetry/opentelemetry-go/commit/2fe8861a24e20088c065b116089862caf9e3cd8b)).
+
+## Pre-Release
+
+First, decide which module sets will be released and update their versions
+in `versions.yaml`. Commit this change to a new branch.
+
+Update go.mod for submodules to depend on the new release which will happen in the next step.
+
+1. Run the `prerelease` make target. It creates a branch
+ `prerelease_<module set>_<new tag>` that will contain all release changes.
+
+ ```
+ make prerelease MODSET=<module set>
+ ```
+
+2. Verify the changes.
+
+ ```
+ git diff ...prerelease_<module set>_<new tag>
+ ```
+
+ This should have changed the version for all modules to be `<new tag>`.
+ If these changes look correct, merge them into your pre-release branch:
+
+ ```go
+ git merge prerelease_<module set>_<new tag>
+ ```
+
+3. Update the [Changelog](./CHANGELOG.md).
+ - Make sure all relevant changes for this release are included and are in language that non-contributors to the project can understand.
+ To verify this, you can look directly at the commits since the `<last tag>`.
+
+ ```
+ git --no-pager log --pretty=oneline "<last tag>..HEAD"
+ ```
+
+ - Move all the `Unreleased` changes into a new section following the title scheme (`[<new tag>] - <date of release>`).
+ - Update all the appropriate links at the bottom.
+
+4. Push the changes to upstream and create a Pull Request on GitHub.
+ Be sure to include the curated changes from the [Changelog](./CHANGELOG.md) in the description.
+
+## Tag
+
+Once the Pull Request with all the version changes has been approved and merged it is time to tag the merged commit.
+
+***IMPORTANT***: It is critical you use the same tag that you used in the Pre-Release step!
+Failure to do so will leave things in a broken state. As long as you do not
+change `versions.yaml` between pre-release and this step, things should be fine.
+
+***IMPORTANT***: [There is currently no way to remove an incorrectly tagged version of a Go module](https://github.com/golang/go/issues/34189).
+It is critical you make sure the version you push upstream is correct.
+[Failure to do so will lead to minor emergencies and tough to work around](https://github.com/open-telemetry/opentelemetry-go/issues/331).
+
+1. For each module set that will be released, run the `add-tags` make target
+ using the `<commit-hash>` of the commit on the main branch for the merged Pull Request.
+
+ ```
+ make add-tags MODSET=<module set> COMMIT=<commit hash>
+ ```
+
+ It should only be necessary to provide an explicit `COMMIT` value if the
+ current `HEAD` of your working directory is not the correct commit.
+
+2. Push tags to the upstream remote (not your fork: `github.com/open-telemetry/opentelemetry-go.git`).
+ Make sure you push all sub-modules as well.
+
+ ```
+ git push upstream <new tag>
+ git push upstream <submodules-path/new tag>
+ ...
+ ```
+
+## Release
+
+Finally create a Release for the new `<new tag>` on GitHub.
+The release body should include all the release notes from the Changelog for this release.
+
+## Verify Examples
+
+After releasing verify that examples build outside of the repository.
+
+```
+./verify_examples.sh
+```
+
+The script copies examples into a different directory removes any `replace` declarations in `go.mod` and builds them.
+This ensures they build with the published release, not the local copy.
+
+## Post-Release
+
+### Contrib Repository
+
+Once verified be sure to [make a release for the `contrib` repository](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/main/RELEASING.md) that uses this release.
+
+### Website Documentation
+
+Update [the documentation](./website_docs) for [the OpenTelemetry website](https://opentelemetry.io/docs/go/).
+Importantly, bump any package versions referenced to be the latest one you just released and ensure all code examples still compile and are accurate.

+# Versioning
+
+This document describes the versioning policy for this repository. This policy
+is designed so the following goals can be achieved.
+
+**Users are provided a codebase of value that is stable and secure.**
+
+## Policy
+
+* Versioning of this project will be idiomatic of a Go project using [Go
+ modules](https://github.com/golang/go/wiki/Modules).
+ * [Semantic import
+ versioning](https://github.com/golang/go/wiki/Modules#semantic-import-versioning)
+ will be used.
+ * Versions will comply with [semver
+ 2.0](https://semver.org/spec/v2.0.0.html) with the following exceptions.
+ * New methods may be added to exported API interfaces. All exported
+ interfaces that fall within this exception will include the following
+ paragraph in their public documentation.
+
+ > Warning: methods may be added to this interface in minor releases.
+
+ * If a module is version `v2` or higher, the major version of the module
+ must be included as a `/vN` at the end of the module paths used in
+ `go.mod` files (e.g., `module go.opentelemetry.io/otel/v2`, `require
+ go.opentelemetry.io/otel/v2 v2.0.1`) and in the package import path
+ (e.g., `import "go.opentelemetry.io/otel/v2/trace"`). This includes the
+ paths used in `go get` commands (e.g., `go get
+ go.opentelemetry.io/otel/v2@v2.0.1`. Note there is both a `/v2` and a
+ `@v2.0.1` in that example. One way to think about it is that the module
+ name now includes the `/v2`, so include `/v2` whenever you are using the
+ module name).
+ * If a module is version `v0` or `v1`, do not include the major version in
+ either the module path or the import path.
+ * Modules will be used to encapsulate signals and components.
+ * Experimental modules still under active development will be versioned at
+ `v0` to imply the stability guarantee defined by
+ [semver](https://semver.org/spec/v2.0.0.html#spec-item-4).
+
+ > Major version zero (0.y.z) is for initial development. Anything MAY
+ > change at any time. The public API SHOULD NOT be considered stable.
+
+ * Mature modules for which we guarantee a stable public API will be versioned
+ with a major version greater than `v0`.
+ * The decision to make a module stable will be made on a case-by-case
+ basis by the maintainers of this project.
+ * Experimental modules will start their versioning at `v0.0.0` and will
+ increment their minor version when backwards incompatible changes are
+ released and increment their patch version when backwards compatible
+ changes are released.
+ * All stable modules that use the same major version number will use the
+ same entire version number.
+ * Stable modules may be released with an incremented minor or patch
+ version even though that module has not been changed, but rather so
+ that it will remain at the same version as other stable modules that
+ did undergo change.
+ * When an experimental module becomes stable a new stable module version
+ will be released and will include this now stable module. The new
+ stable module version will be an increment of the minor version number
+ and will be applied to all existing stable modules as well as the newly
+ stable module being released.
+* Versioning of the associated [contrib
+ repository](https://github.com/open-telemetry/opentelemetry-go-contrib) of
+ this project will be idiomatic of a Go project using [Go
+ modules](https://github.com/golang/go/wiki/Modules).
+ * [Semantic import
+ versioning](https://github.com/golang/go/wiki/Modules#semantic-import-versioning)
+ will be used.
+ * Versions will comply with [semver 2.0](https://semver.org/spec/v2.0.0.html).
+ * If a module is version `v2` or higher, the
+ major version of the module must be included as a `/vN` at the end of the
+ module paths used in `go.mod` files (e.g., `module
+ go.opentelemetry.io/contrib/instrumentation/host/v2`, `require
+ go.opentelemetry.io/contrib/instrumentation/host/v2 v2.0.1`) and in the
+ package import path (e.g., `import
+ "go.opentelemetry.io/contrib/instrumentation/host/v2"`). This includes
+ the paths used in `go get` commands (e.g., `go get
+ go.opentelemetry.io/contrib/instrumentation/host/v2@v2.0.1`. Note there
+ is both a `/v2` and a `@v2.0.1` in that example. One way to think about
+ it is that the module name now includes the `/v2`, so include `/v2`
+ whenever you are using the module name).
+ * If a module is version `v0` or `v1`, do not include the major version
+ in either the module path or the import path.
+ * In addition to public APIs, telemetry produced by stable instrumentation
+ will remain stable and backwards compatible. This is to avoid breaking
+ alerts and dashboard.
+ * Modules will be used to encapsulate instrumentation, detectors, exporters,
+ propagators, and any other independent sets of related components.
+ * Experimental modules still under active development will be versioned at
+ `v0` to imply the stability guarantee defined by
+ [semver](https://semver.org/spec/v2.0.0.html#spec-item-4).
+
+ > Major version zero (0.y.z) is for initial development. Anything MAY
+ > change at any time. The public API SHOULD NOT be considered stable.
+
+ * Mature modules for which we guarantee a stable public API and telemetry will
+ be versioned with a major version greater than `v0`.
+ * Experimental modules will start their versioning at `v0.0.0` and will
+ increment their minor version when backwards incompatible changes are
+ released and increment their patch version when backwards compatible
+ changes are released.
+ * Stable contrib modules cannot depend on experimental modules from this
+ project.
+ * All stable contrib modules of the same major version with this project
+ will use the same entire version as this project.
+ * Stable modules may be released with an incremented minor or patch
+ version even though that module's code has not been changed. Instead
+ the only change that will have been included is to have updated that
+ modules dependency on this project's stable APIs.
+ * When an experimental module in contrib becomes stable a new stable
+ module version will be released and will include this now stable
+ module. The new stable module version will be an increment of the minor
+ version number and will be applied to all existing stable contrib
+ modules, this project's modules, and the newly stable module being
+ released.
+ * Contrib modules will be kept up to date with this project's releases.
+ * Due to the dependency contrib modules will implicitly have on this
+ project's modules the release of stable contrib modules to match the
+ released version number will be staggered after this project's release.
+ There is no explicit time guarantee for how long after this projects
+ release the contrib release will be. Effort should be made to keep them
+ as close in time as possible.
+ * No additional stable release in this project can be made until the
+ contrib repository has a matching stable release.
+ * No release can be made in the contrib repository after this project's
+ stable release except for a stable release of the contrib repository.
+* GitHub releases will be made for all releases.
+* Go modules will be made available at Go package mirrors.
+
+## Example Versioning Lifecycle
+
+To better understand the implementation of the above policy the following
+example is provided. 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`

+# OpenTelemetry-Go Jaeger Exporter
+
+[](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger)
+
+[OpenTelemetry span exporter for Jaeger](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/sdk_exporters/jaeger.md) implementation.
+
+## Installation
+
+```
+go get -u go.opentelemetry.io/otel/exporters/jaeger
+```
+
+## Example
+
+See [../../example/jaeger](../../example/jaeger).
+
+## Configuration
+
+The exporter can be used to send spans to:
+
+- Jaeger agent using `jaeger.thrift` over compact thrift protocol via
+ [`WithAgentEndpoint`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithAgentEndpoint) option.
+- Jaeger collector using `jaeger.thrift` over HTTP via
+ [`WithCollectorEndpoint`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithCollectorEndpoint) option.
+
+### Environment Variables
+
+The following environment variables can be used
+(instead of options objects) to override the default configuration.
+
+| Environment variable | Option | Default value |
+| --------------------------------- | --------------------------------------------------------------------------------------------- | ----------------------------------- |
+| `OTEL_EXPORTER_JAEGER_AGENT_HOST` | [`WithAgentHost`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithAgentHost) | `localhost` |
+| `OTEL_EXPORTER_JAEGER_AGENT_PORT` | [`WithAgentPort`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithAgentPort) | `6831` |
+| `OTEL_EXPORTER_JAEGER_ENDPOINT` | [`WithEndpoint`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithEndpoint) | `http://localhost:14268/api/traces` |
+| `OTEL_EXPORTER_JAEGER_USER` | [`WithUsername`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithUsername) | |
+| `OTEL_EXPORTER_JAEGER_PASSWORD` | [`WithPassword`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/jaeger#WithPassword) | |
+
+Configuration using options have precedence over the environment variables.
+
+## Contributing
+
+This exporter uses a vendored copy of the Apache Thrift library (v0.14.1) at a custom import path.
+When re-generating Thrift code in the future, please adapt import paths as necessary.

+# OpenTelemetry-Go OTLP Span Exporter
+
+[](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
+
+[OpenTelemetry Protocol Exporter](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.5.0/specification/protocol/exporter.md) implementation.
+
+## Installation
+
+```
+go get -u go.opentelemetry.io/otel/exporters/otlp/otlptrace
+```
+
+## Examples
+
+- [HTTP Exporter setup and examples](./otlptracehttp/example_test.go)
+- [Full example of gRPC Exporter sending telemetry to a local collector](../../../example/otel-collector)
+
+## [`otlptrace`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
+
+The `otlptrace` package provides an exporter implementing the OTel span exporter interface.
+This exporter is configured using a client satisfying the `otlptrace.Client` interface.
+This client handles the transformation of data into wire format and the transmission of that data to the collector.
+
+## [`otlptracegrpc`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc)
+
+The `otlptracegrpc` package implements a client for the span exporter that sends trace telemetry data to the collector using gRPC with protobuf-encoded payloads.
+
+## [`otlptracehttp`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp)
+
+The `otlptracehttp` package implements a client for the span exporter that sends trace telemetry data to the collector using HTTP with protobuf-encoded payloads.
+
+## Configuration
+
+### Environment Variables
+
+The following environment variables can be used (instead of options objects) to
+override the default configuration. For more information about how each of
+these environment variables is interpreted, see [the OpenTelemetry
+specification](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.8.0/specification/protocol/exporter.md).
+
+| Environment variable | Option | Default value |
+| ------------------------------------------------------------------------ |------------------------------ | -------------------------------------------------------- |
+| `OTEL_EXPORTER_OTLP_ENDPOINT` `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT` | `WithEndpoint` `WithInsecure` | `https://localhost:4317` or `https://localhost:4318`[^1] |
+| `OTEL_EXPORTER_OTLP_CERTIFICATE` `OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE` | `WithTLSClientConfig` | |
+| `OTEL_EXPORTER_OTLP_HEADERS` `OTEL_EXPORTER_OTLP_TRACES_HEADERS` | `WithHeaders` | |
+| `OTEL_EXPORTER_OTLP_COMPRESSION` `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION` | `WithCompression` | |
+| `OTEL_EXPORTER_OTLP_TIMEOUT` `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT` | `WithTimeout` | `10s` |
+
+[^1]: The gRPC client defaults to `https://localhost:4317` and the HTTP client `https://localhost:4318`.
+
+Configuration using options have precedence over the environment variables.

+Package trace provides an implementation of the tracing part of the
+OpenTelemetry API.
+
+To participate in distributed traces a Span needs to be created for the
+operation being performed as part of a traced workflow. In its simplest form:
+
+ var tracer trace.Tracer
+
+ func init() {
+ tracer = otel.Tracer("instrumentation/package/name")
+ }
+
+ func operation(ctx context.Context) {
+ var span trace.Span
+ ctx, span = tracer.Start(ctx, "operation")
+ defer span.End()
+ // ...
+ }
+
+A Tracer is unique to the instrumentation and is used to create Spans.
+Instrumentation should be designed to accept a TracerProvider from which it
+can create its own unique Tracer. Alternatively, the registered global
+TracerProvider from the go.opentelemetry.io/otel package can be used as
+a default.
+
+ const (
+ name = "instrumentation/package/name"
+ version = "0.1.0"
+ )
+
+ type Instrumentation struct {
+ tracer trace.Tracer
+ }
+
+ func NewInstrumentation(tp trace.TracerProvider) *Instrumentation {
+ if tp == nil {
+ tp = otel.TracerProvider()
+ }
+ return &Instrumentation{
+ tracer: tp.Tracer(name, trace.WithInstrumentationVersion(version)),
+ }
+ }
+
+ func operation(ctx context.Context, inst *Instrumentation) {
+ var span trace.Span
+ ctx, span = inst.tracer.Start(ctx, "operation")
+ defer span.End()

+Package trace implements tracing of requests and long-lived objects.
+It exports HTTP interfaces on /debug/requests and /debug/events.
+
+A trace.Trace provides tracing for short-lived objects, usually requests.
+A request handler might be implemented like this:
+
+ func fooHandler(w http.ResponseWriter, req *http.Request) {
+ tr := trace.New("mypkg.Foo", req.URL.Path)
+ defer tr.Finish()
+ ...
+ tr.LazyPrintf("some event %q happened", str)
+ ...
+ if err := somethingImportant(); err != nil {
+ tr.LazyPrintf("somethingImportant failed: %v", err)
+ tr.SetError()
+ }
+ }
+
+The /debug/requests HTTP endpoint organizes the traces by family,
+errors, and duration. It also provides histogram of request duration
+for each family.
+
+A trace.EventLog provides tracing for long-lived objects, such as RPC
+connections.
+
+ // A Fetcher fetches URL paths for a single domain.
+ type Fetcher struct {
+ domain string
+ events trace.EventLog
+ }
+
+ func NewFetcher(domain string) *Fetcher {
+ return &Fetcher{
+ domain,
+ trace.NewEventLog("mypkg.Fetcher", domain),
+ }
+ }
+
+ func (f *Fetcher) Fetch(path string) (string, error) {
+ resp, err := http.Get("http://" + f.domain + "/" + path)
+ if err != nil {
+ f.events.Errorf("Get(%q) = %v", path, err)
+ return "", err
+ }
+ f.events.Printf("Get(%q) = %s", path, resp.Status)
+ ...
+ }
+
+ func (f *Fetcher) Close() error {
+ f.events.Finish()
+ return nil
+ }
+
+The /debug/events HTTP endpoint organizes the event logs by family and
+by time since the last error. The expanded view displays recent log
+entries and the log's call stack.

+# How to contribute
+
+We definitely welcome your patches and contributions to gRPC! Please read the gRPC
+organization's [governance rules](https://github.com/grpc/grpc-community/blob/master/governance.md)
+and [contribution guidelines](https://github.com/grpc/grpc-community/blob/master/CONTRIBUTING.md) before proceeding.
+
+If you are new to github, please start by reading [Pull Request howto](https://help.github.com/articles/about-pull-requests/)
+
+## Legal requirements
+
+In order to protect both you and ourselves, you will need to sign the
+[Contributor License Agreement](https://identity.linuxfoundation.org/projects/cncf).
+
+## Guidelines for Pull Requests
+How to get your contributions merged smoothly and quickly.
+
+- Create **small PRs** that are narrowly focused on **addressing a single
+ concern**. We often times receive PRs that are trying to fix several things at
+ a time, but only one fix is considered acceptable, nothing gets merged and
+ both author's & review's time is wasted. Create more PRs to address different
+ concerns and everyone will be happy.
+
+- The grpc package should only depend on standard Go packages and a small number
+ of exceptions. If your contribution introduces new dependencies which are NOT
+ in the [list](https://godoc.org/google.golang.org/grpc?imports), you need a
+ discussion with gRPC-Go authors and consultants.
+
+- For speculative changes, consider opening an issue and discussing it first. If
+ you are suggesting a behavioral or API change, consider starting with a [gRFC
+ proposal](https://github.com/grpc/proposal).
+
+- Provide a good **PR description** as a record of **what** change is being made
+ and **why** it was made. Link to a github issue if it exists.
+
+- Don't fix code style and formatting unless you are already changing that line
+ to address an issue. PRs with irrelevant changes won't be merged. If you do
+ want to fix formatting or style, do that in a separate PR.
+
+- Unless your PR is trivial, you should expect there will be reviewer comments
+ that you'll need to address before merging. We expect you to be reasonably
+ responsive to those comments, otherwise the PR will be closed after 2-3 weeks
+ of inactivity.
+
+- Maintain **clean commit history** and use **meaningful commit messages**. PRs
+ with messy commit history are difficult to review and won't be merged. Use
+ `rebase -i upstream/master` to curate your commit history and/or to bring in
+ latest changes from master (but avoid rebasing in the middle of a code
+ review).
+
+- Keep your PR up to date with upstream/master (if there are merge conflicts, we
+ can't really merge your change).
+
+- **All tests need to be passing** before your change can be merged. We
+ recommend you **run tests locally** before creating your PR to catch breakages
+ early on.
+ - `VET_SKIP_PROTO=1 ./vet.sh` to catch vet errors
+ - `go test -cpu 1,4 -timeout 7m ./...` to run the tests
+ - `go test -race -cpu 1,4 -timeout 7m ./...` to run tests in race mode
+
+- Exceptions to the rules can be made if there's a compelling reason for doing so.

+# gRPC-Go
+
+[](https://travis-ci.org/grpc/grpc-go)
+[][API]
+[](https://goreportcard.com/report/github.com/grpc/grpc-go)
+
+The [Go][] implementation of [gRPC][]: A high performance, open source, general
+RPC framework that puts mobile and HTTP/2 first. For more information see the
+[Go gRPC docs][], or jump directly into the [quick start][].
+
+## Prerequisites
+
+- **[Go][]**: any one of the **three latest major** [releases][go-releases].
+
+## Installation
+
+With [Go module][] support (Go 1.11+), simply add the following import
+
+```go
+import "google.golang.org/grpc"
+```
+
+to your code, and then `go [build|run|test]` will automatically fetch the
+necessary dependencies.
+
+Otherwise, to install the `grpc-go` package, run the following command:
+
+```console
+$ go get -u google.golang.org/grpc
+```
+
+> **Note:** If you are trying to access `grpc-go` from **China**, see the
+> [FAQ](#FAQ) below.
+
+## Learn more
+
+- [Go gRPC docs][], which include a [quick start][] and [API
+ reference][API] among other resources
+- [Low-level technical docs](Documentation) from this repository
+- [Performance benchmark][]
+- [Examples](examples)
+
+## FAQ
+
+### I/O Timeout Errors
+
+The `golang.org` domain may be blocked from some countries. `go get` usually
+produces an error like the following when this happens:
+
+```console
+$ go get -u google.golang.org/grpc
+package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc" (https fetch: Get https://google.golang.org/grpc?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)
+```
+
+To build Go code, there are several options:
+
+- Set up a VPN and access google.golang.org through that.
+
+- Without Go module support: `git clone` the repo manually:
+
+ ```sh
+ git clone https://github.com/grpc/grpc-go.git $GOPATH/src/google.golang.org/grpc
+ ```
+
+ You will need to do the same for all of grpc's dependencies in `golang.org`,
+ e.g. `golang.org/x/net`.
+
+- With Go module support: it is possible to use the `replace` feature of `go
+ mod` to create aliases for golang.org packages. In your project's directory:
+
+ ```sh
+ go mod edit -replace=google.golang.org/grpc=github.com/grpc/grpc-go@latest
+ go mod tidy
+ go mod vendor
+ go build -mod=vendor
+ ```
+
+ Again, this will need to be done for all transitive dependencies hosted on
+ golang.org as well. For details, refer to [golang/go issue #28652](https://github.com/golang/go/issues/28652).
+
+### Compiling error, undefined: grpc.SupportPackageIsVersion
+
+#### If you are using Go modules:
+
+Ensure your gRPC-Go version is `require`d at the appropriate version in
+the same module containing the generated `.pb.go` files. For example,
+`SupportPackageIsVersion6` needs `v1.27.0`, so in your `go.mod` file:
+
+```go
+module <your module name>
+
+require (
+ google.golang.org/grpc v1.27.0
+)
+```
+
+#### If you are *not* using Go modules:
+
+Update the `proto` package, gRPC package, and rebuild the `.proto` files:
+
+```sh
+go get -u github.com/golang/protobuf/{proto,protoc-gen-go}
+go get -u google.golang.org/grpc
+protoc --go_out=plugins=grpc:. *.proto
+```
+
+### How to turn on logging
+
+The default logger is controlled by environment variables. Turn everything on
+like this:
+
+```console
+$ export GRPC_GO_LOG_VERBOSITY_LEVEL=99
+$ export GRPC_GO_LOG_SEVERITY_LEVEL=info
+```
+
+### The RPC failed with error `"code = Unavailable desc = transport is closing"`
+
+This error means the connection the RPC is using was closed, and there are many
+possible reasons, including:
+ 1. mis-configured transport credentials, connection failed on handshaking
+ 1. bytes disrupted, possibly by a proxy in between
+ 1. server shutdown
+ 1. Keepalive parameters caused connection shutdown, for example if you have configured
+ your server to terminate connections regularly to [trigger DNS lookups](https://github.com/grpc/grpc-go/issues/3170#issuecomment-552517779).
+ If this is the case, you may want to increase your [MaxConnectionAgeGrace](https://pkg.go.dev/google.golang.org/grpc/keepalive?tab=doc#ServerParameters),
+ to allow longer RPC calls to finish.
+
+It can be tricky to debug this because the error happens on the client side but
+the root cause of the connection being closed is on the server side. Turn on
+logging on __both client and server__, and see if there are any transport
+errors.

+// source: google/protobuf/any.proto
+
+// Package anypb contains generated types for google/protobuf/any.proto.
+//
+// The Any message is a dynamic representation of any other message value.
+// It is functionally a tuple of the full name of the remote message type and
+// the serialized bytes of the remote message value.
+//
+//
+// Constructing an Any
+//
+// An Any message containing another message value is constructed using New:
+//
+// any, err := anypb.New(m)
+// if err != nil {
+// ... // handle error
+// }
+// ... // make use of any
+//
+//
+// Unmarshaling an Any
+//
+// With a populated Any message, the underlying message can be serialized into
+// a remote concrete message value in a few ways.
+//
+// If the exact concrete type is known, then a new (or pre-existing) instance
+// of that message can be passed to the UnmarshalTo method:
+//
+// m := new(foopb.MyMessage)
+// if err := any.UnmarshalTo(m); err != nil {
+// ... // handle error
+// }
+// ... // make use of m
+//
+// If the exact concrete type is not known, then the UnmarshalNew method can be
+// used to unmarshal the contents into a new instance of the remote message type:
+//
+// m, err := any.UnmarshalNew()
+// if err != nil {
+// ... // handle error
+// }
+// ... // make use of m
+//
+// UnmarshalNew uses the global type registry to resolve the message type and
+// construct a new instance of that message to unmarshal into. In order for a
+// message type to appear in the global registry, the Go type representing that
+// protobuf message type must be linked into the Go binary. For messages
+// generated by protoc-gen-go, this is achieved through an import of the
+// generated Go package representing a .proto file.
+//
+// A common pattern with UnmarshalNew is to use a type switch with the resulting
+// proto.Message value:
+//
+// switch m := m.(type) {
+// case *foopb.MyMessage:
+// ... // make use of m as a *foopb.MyMessage
+// case *barpb.OtherMessage:
+// ... // make use of m as a *barpb.OtherMessage
+// case *bazpb.SomeMessage:
+// ... // make use of m as a *bazpb.SomeMessage
+// }
+//
+// This pattern ensures that the generated packages containing the message types
+// listed in the case clauses are linked into the Go binary and therefore also
+// registered in the global registry.
+//
+//
+// Type checking an Any
+//
+// In order to type check whether an Any message represents some other message,
+// then use the MessageIs method:
+//
+// if any.MessageIs((*foopb.MyMessage)(nil)) {
+// ... // make use of any, knowing that it contains a foopb.MyMessage
+// }
+//
+// The MessageIs method can also be used with an allocated instance of the target
+// message type if the intention is to unmarshal into it if the type matches:
+//
+// m := new(foopb.MyMessage)
+// if any.MessageIs(m) {
+// if err := any.UnmarshalTo(m); err != nil {
+// ... // handle error
+// }
+// ... // make use of m
+// }
+//

+// `Any` contains an arbitrary serialized protocol buffer message along with a
+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+// Foo foo = ...;
+// Any any;
+// any.PackFrom(foo);
+// ...
+// if (any.UnpackTo(&foo)) {
+// ...
+// }
+//
+// Example 2: Pack and unpack a message in Java.
+//
+// Foo foo = ...;
+// Any any = Any.pack(foo);
+// ...
+// if (any.is(Foo.class)) {
+// foo = any.unpack(Foo.class);
+// }
+//
+// Example 3: Pack and unpack a message in Python.
+//
+// foo = Foo(...)
+// any = Any()
+// any.Pack(foo)
+// ...
+// if any.Is(Foo.DESCRIPTOR):
+// any.Unpack(foo)
+// ...
+//
+// Example 4: Pack and unpack a message in Go
+//
+// foo := &pb.Foo{...}
+// any, err := anypb.New(foo)
+// if err != nil {
+// ...
+// }
+// ...
+// foo := &pb.Foo{}
+// if err := any.UnmarshalTo(foo); err != nil {
+// ...
+// }
+//
+// The pack methods provided by protobuf library will by default use
+// 'type.googleapis.com/full.type.name' as the type URL and the unpack
+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+// package google.profile;
+// message Person {
+// string first_name = 1;
+// string last_name = 2;
+// }
+//
+// {
+// "@type": "type.googleapis.com/google.profile.Person",
+// "firstName": <string>,
+// "lastName": <string>
+// }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+// {
+// "@type": "type.googleapis.com/google.protobuf.Duration",
+// "value": "1.212s"
+// }
+//
+type Any struct {
+ state protoimpl.MessageState
+ sizeCache protoimpl.SizeCache
+ unknownFields protoimpl.UnknownFields
+
+ // A URL/resource name that uniquely identifies the type of the serialized
+ // protocol buffer message. This string must contain at least
+ // one "/" character. The last segment of the URL's path must represent
+ // the fully qualified name of the type (as in
+ // `path/google.protobuf.Duration`). The name should be in a canonical form
+ // (e.g., leading "." is not accepted).
+ //
+ // In practice, teams usually precompile into the binary all types that they
+ // expect it to use in the context of Any. However, for URLs which use the
+ // scheme `http`, `https`, or no scheme, one can optionally set up a type
+ // server that maps type URLs to message definitions as follows:
+ //
+ // * If no scheme is provided, `https` is assumed.
+ // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+ // value in binary format, or produce an error.
+ // * Applications are allowed to cache lookup results based on the
+ // URL, or have them precompiled into a binary to avoid any
+ // lookup. Therefore, binary compatibility needs to be preserved
+ // on changes to types. (Use versioned type names to manage
+ // breaking changes.)
+ //
+ // Note: this functionality is not currently available in the official
+ // protobuf release, and it is not used for type URLs beginning with
+ // type.googleapis.com.
+ //
+ // Schemes other than `http`, `https` (or the empty scheme) might be

+//
+// The AsDuration method can be used to convert a Duration message to a

+// d := dur.AsDuration()
+// ... // make use of d as a time.Duration
+//
+// Converting to a time.Duration is a common operation so that the extensive
+// set of time-based operations provided by the time package can be leveraged.
+// See https://golang.org/pkg/time for more information.
+//
+// The AsDuration method performs the conversion on a best-effort basis.
+// Durations with denormal values (e.g., nanoseconds beyond -99999999 and
+// +99999999, inclusive; or seconds and nanoseconds with opposite signs)
+// are normalized during the conversion to a time.Duration. To manually check for
+// invalid Duration per the documented limitations in duration.proto,
+// additionally call the CheckValid method:
+//
+// if err := dur.CheckValid(); err != nil {
+// ... // handle error
+// }
+//
+// Note that the documented limitations in duration.proto does not protect a
+// Duration from overflowing the representable range of a time.Duration in Go.
+// The AsDuration method uses saturation arithmetic such that an overflow clamps
+// the resulting value to the closest representable value (e.g., math.MaxInt64
+// for positive overflow and math.MinInt64 for negative overflow).
+//
+//
+// Conversion from a Go Duration
+//

+// A Duration represents a signed, fixed-length span of time represented

+// other definitions may be used. Where the mask applies will be
+// clearly documented together with its declaration in the API. In
+// any case, the effect on the returned resource/resources is required
+// behavior for APIs.
+//
+// # Field Masks in Update Operations
+//
+// A field mask in update operations specifies which fields of the
+// targeted resource are going to be updated. The API is required
+// to only change the values of the fields as specified in the mask
+// and leave the others untouched. If a resource is passed in to
+// describe the updated values, the API ignores the values of all
+// fields not covered by the mask.
+//
+// If a repeated field is specified for an update operation, new values will
+// be appended to the existing repeated field in the target resource. Note that
+// a repeated field is only allowed in the last position of a `paths` string.
+//
+// If a sub-message is specified in the last position of the field mask for an
+// update operation, then new value will be merged into the existing sub-message
+// in the target resource.
+//
+// For example, given the target message:
+//
+// f {
+// b {
+// d: 1
+// x: 2
+// }
+// c: [1]
+// }
+//
+// And an update message:
+//
+// f {
+// b {
+// d: 10
+// }
+// c: [2]
+// }
+//
+// then if the field mask is:
+//
+// paths: ["f.b", "f.c"]
+//
+// then the result will be:
+//
+// f {
+// b {
+// d: 10
+// x: 2
+// }
+// c: [1, 2]
+// }
+//
+// An implementation may provide options to override this default behavior for
+// repeated and message fields.
+//
+// In order to reset a field's value to the default, the field must
+// be in the mask and set to the default value in the provided resource.
+// Hence, in order to reset all fields of a resource, provide a default
+// instance of the resource and set all fields in the mask, or do
+// not provide a mask as described below.
+//
+// If a field mask is not present on update, the operation applies to
+// all fields (as if a field mask of all fields has been specified).
+// Note that in the presence of schema evolution, this may mean that
+// fields the client does not know and has therefore not filled into
+// the request will be reset to their default. If this is unwanted
+// behavior, a specific service may require a client to always specify
+// a field mask, producing an error if not.
+//
+// As with get operations, the location of the resource which
+// describes the updated values in the request message depends on the
+// operation kind. In any case, the effect of the field mask is
+// required to be honored by the API.
+//
+// ## Considerations for HTTP REST
+//
+// The HTTP kind of an update operation which uses a field mask must
+// be set to PATCH instead of PUT in order to satisfy HTTP semantics
+// (PUT must only be used for full updates).
+//
+// # JSON Encoding of Field Masks
+//
+// In JSON, a field mask is encoded as a single string where paths are
+// separated by a comma. Fields name in each path are converted
+// to/from lower-camel naming conventions.
+//
+// As an example, consider the following message declarations:
+//
+// message Profile {
+// User user = 1;
+// Photo photo = 2;
+// }
+// message User {
+// string display_name = 1;
+// string address = 2;
+// }
+//
+// In proto a field mask for `Profile` may look as such:
+//
+// mask {
+// paths: "user.display_name"
+// paths: "photo"
+// }
+//
+// In JSON, the same mask is represented as below:
+//
+// {
+// mask: "user.displayName,photo"
+// }
+//
+// # Field Masks and Oneof Fields
+//
+// Field masks treat fields in oneofs just as regular fields. Consider the
+// following message:
+//
+// message SampleMessage {
+// oneof test_oneof {
+// string name = 4;
+// SubMessage sub_message = 9;
+// }
+// }
+//
+// The field mask can be:
+//
+// mask {
+// paths: "name"
+// }
+//
+// Or:
+//
+// mask {
+// paths: "sub_message"
+// }
+//
+// Note that oneof type names ("test_oneof" in this case) cannot be used in
+// paths.
+//
+// ## Field Mask Verification
+//
+// The implementation of any API method which has a FieldMask type field in the
+// request should verify the included field paths, and return an
+// `INVALID_ARGUMENT` error if any path is unmappable.

+// The Timestamp message represents a timestamp,
+// an instant in time since the Unix epoch (January 1st, 1970).
+//
+//
+// Conversion to a Go Time
+//
+// The AsTime method can be used to convert a Timestamp message to a
+// standard Go time.Time value in UTC:
+//
+// t := ts.AsTime()
+// ... // make use of t as a time.Time
+//
+// Converting to a time.Time is a common operation so that the extensive
+// set of time-based operations provided by the time package can be leveraged.
+// See https://golang.org/pkg/time for more information.
+//
+// The AsTime method performs the conversion on a best-effort basis. Timestamps
+// with denormal values (e.g., nanoseconds beyond 0 and 99999999, inclusive)
+// are normalized during the conversion to a time.Time. To manually check for
+// invalid Timestamps per the documented limitations in timestamp.proto,
+// additionally call the CheckValid method:
+//
+// if err := ts.CheckValid(); err != nil {
+// ... // handle error
+// }
+//
+//
+// Conversion from a Go Time
+//
+// The timestamppb.New function can be used to construct a Timestamp message
+// from a standard Go time.Time value:
+//
+// ts := timestamppb.New(t)
+// ... // make use of ts as a *timestamppb.Timestamp
+//
+// In order to construct a Timestamp representing the current time, use Now:
+//
+// ts := timestamppb.Now()
+// ... // make use of ts as a *timestamppb.Timestamp

+//
+// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+//
+// struct timeval tv;
+// gettimeofday(&tv, NULL);
+//
+// Timestamp timestamp;
+// timestamp.set_seconds(tv.tv_sec);
+// timestamp.set_nanos(tv.tv_usec * 1000);
+//
+// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+//
+// FILETIME ft;
+// GetSystemTimeAsFileTime(&ft);
+// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+//
+// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+// Timestamp timestamp;

+// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+//
+// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+//
+// long millis = System.currentTimeMillis();
+//
+// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+// .setNanos((int) ((millis % 1000) * 1000000)).build();
+//
+//
+// Example 5: Compute Timestamp from Java `Instant.now()`.
+//
+// Instant now = Instant.now();
+//
+// Timestamp timestamp =
+// Timestamp.newBuilder().setSeconds(now.getEpochSecond())
+// .setNanos(now.getNano()).build();
+//
+//
+// Example 6: Compute Timestamp from current time in Python.
+//
+// timestamp = Timestamp()
+// timestamp.GetCurrentTime()

+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required. A proto3 JSON serializer should always use UTC (as indicated by
+// "Z") when printing the Timestamp type and a proto3 JSON parser should be
+// able to accept both UTC and other timezones (as indicated by an offset).
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard
+// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using
+// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+// the Joda Time's [`ISODateTimeFormat.dateTime()`](
+// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
+// ) to obtain a formatter capable of generating timestamps in this format.
