+# A minimal logging API for Go
+
+[![Go Reference](https://pkg.go.dev/badge/github.com/go-logr/logr.svg)](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)
+- **github.com/google/glog**: [glogr](https://github.com/go-logr/glogr)
+- **k8s.io/klog** (for Kubernetes): [klogr](https://git.k8s.io/klog/klogr)
+- **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)
+
+## 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.
+//
+// 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

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,

 ## [Unreleased]
 
+## [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
+### 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)

 - 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 coss-cutting concerns as a `map[string]string` held in memory. (#2334)

 ### Compatibility
 
+OpenTelemetry-Go attempts to track the current supported versions of the
+[Go language](https://golang.org/doc/devel/release#policy). The release
+schedule after a new minor version of go is as follows:
+
+- The first release or one month, which ever is sooner, will add build steps for the new go version.
+- The first release after three months will remove support for the oldest go version.
