# A more minimal logging API for Go
Before you consider this package, please read [this blog post by the inimitable
Dave Cheney](http://dave.cheney.net/2015/11/05/lets-talk-about-logging). I
really appreciate what he has to say, and it largely aligns with my own
experiences. Too many choices of levels means inconsistent logs.
This package offers a purely abstract interface, based on these ideas but with
a few twists. Code can depend on just this interface and have the actual
logging implementation be injected from callers. Ideally only `main()` knows
what logging implementation is being used.
# 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()`. I disagree, especially when you consider things like output
locations, timestamps, file and line decorations, and structured logging. I
restrict the 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.
This is a BETA grade API. I have implemented it for
[glog](https://godoc.org/github.com/golang/glog). Until there is a significant
2nd implementation, I don't really know how it will change.

// Package logr defines abstract interfaces for logging. Packages can depend on
// these interfaces and callers can implement logging in whatever way is
// appropriate.
//
// This design derives from Dave Cheney's blog:
// http://dave.cheney.net/2015/11/05/lets-talk-about-logging
//
// This is a BETA grade API. Until there is a significant 2nd implementation,
// I don't really know how it will change.
//
// The logging specifically makes it non-trivial to use format strings, to encourage
// attaching structured information instead of unstructured format strings.
//
// Usage
//
// Logging is done using a Logger. Loggers can have name prefixes and named values
// attached, so that all log messages logged with that Logger have some base context
// associated.
//
// The term "key" is used to refer to the name associated with a particular value, to
// disambiguate it from the general Logger name.
//
// For instance, suppose we're trying to reconcile the state of an object, and we want
// to log that we've made some decision.
//
// With the traditional 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's structured logging, we'd write
// // elsewhere in the file, set up the logger to log with the prefix of "reconcilers",
// // and the named value target-type=Foo, for extra context.
// log := mainLogger.WithName("reconcilers").WithValues("target-type", "Foo")
//
// // later on...
// log.Info("setting field foo on object", "value", targetValue, "object", object)
//
// Depending on our logging implementation, we could then make logging decisions based on field values
// (like only logging such events for objects in a certain namespace), or copy the structured
// information into a structured log store.
//
// For logging errors, Logger has a method called Error. Suppose we wanted to log an
// error while reconciling. With the traditional log package, we might write
// log.Errorf("unable to reconcile object %s/%s: %v", object.Namespace, object.Name, err)
//
// With logr, we'd instead write
// // assuming the above setup for log
// log.Error(err, "unable to reconcile object", "object", object)
//
// This functions similarly to:
// log.Info("unable to reconcile object", "error", err, "object", object)
//
// However, it ensures that a standard key for the error value ("error") is used across all
// error logging. Furthermore, certain implementations may choose to attach additional
// information (such as stack traces) on calls to Error, so it's preferred to use Error
// to log errors.
//
// Parts of a log line
//
// Each log message from a Logger has four types of context:
// logger name, log verbosity, log message, and the named values.
//
// The Logger name constists of a series of name "segments" added by successive calls to WithName.
// These name segments will be joined in some way by the underlying implementation. It is strongly
// reccomended that name segements 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).
//
// Log verbosity represents how little a log matters. Level zero, the default, matters most.
// Increasing levels matter less and less. Try to avoid lots of different verbosity levels,
// and instead provide useful keys, logger names, and log messages for users to filter on.
// It's illegal to pass a log level below zero.
//
// The log message consists of a constant message attached to the the log line. This
// should generally be a simple description of what's occuring, and should never be a format string.
//
// Variable information can then be attached using named values (key/value pairs). Keys are arbitrary
// strings, while values may be any Go value.
//
// Key Naming Conventions
//
// 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:
//
// - `"error"`: the underlying error value in the `Error` method.
// - `"stacktrace"`: the stack trace associated with a particular log line or error
// (often from the `Error` message).
// - `"caller"`: the calling information (file/line) of a particular log line.
// - `"msg"`: the log message.
// - `"level"`: the log level.
// - `"ts"`: the timestamp for a log line.
//
// Implementations are encouraged to make use of these keys to represent the above
// concepts, when neccessary (for example, in a pure-JSON output form, it would be
// necessary to represent at least message and timestamp as ordinary named values).
package logr
// TODO: consider adding back in format strings if they're really needed
// TODO: consider other bits of zap/zapcore functionality like ObjectMarshaller (for arbitrary objects)
// TODO: consider other bits of glog functionality like Flush, InfoDepth, OutputStats
// InfoLogger represents the ability to log non-error messages, at a particular verbosity.
type InfoLogger interface {
// Info logs a non-error message with the given key/value pairs as context.
//
// The msg argument should be used to add some constant description to
// the log line. The key/value pairs can then be used to add additional
// variable information. The key/value pairs should alternate string
// keys and arbitrary values.
Info(msg string, keysAndValues ...interface{})
// Enabled tests whether this InfoLogger is enabled. For example,
// commandline flags might be used to set the logging verbosity and disable
// some info logs.
Enabled() bool
}
// Logger represents the ability to log messages, both errors and not.
type Logger interface {
// All Loggers implement InfoLogger. Calling InfoLogger methods directly on
// a Logger value is equivalent to calling them on a V(0) InfoLogger. For
// example, logger.Info() produces the same result as logger.V(0).Info.
InfoLogger
// Error logs an error, with the given message and key/value pairs as context.
// It functions similarly to calling Info with the "error" named value, but may
// have unique behavior, and should be preferred for logging errors (see the
// package documentations for more information).
//
// The msg field should be used to add context to any underlying error,
// while the err field should be used to attach the actual error that
// triggered this log line, if present.
Error(err error, msg string, keysAndValues ...interface{})
// V returns an InfoLogger value for a specific verbosity level. A higher
// verbosity level means a log message is less important. It's illegal to

klog
====
klog is a permanent fork of https://github.com/golang/glog.
## Why was klog created?
The decision to create klog was one that wasn't made lightly, but it was necessary due to some
drawbacks that are present in [glog](https://github.com/golang/glog). Ultimately, the fork was created due to glog not being under active development; this can be seen in the glog README:
> The code in this repo [...] is not itself under development
This makes us unable to solve many use cases without a fork. The factors that contributed to needing feature development are listed below:
* `glog` [presents a lot "gotchas"](https://github.com/kubernetes/kubernetes/issues/61006) and introduces challenges in containerized environments, all of which aren't well documented.
* `glog` doesn't provide an easy way to test logs, which detracts from the stability of software using it
* A long term goal is to implement a logging interface that allows us to add context, change output format, etc.
Historical context is available here:
* https://github.com/kubernetes/kubernetes/issues/61006
* https://github.com/kubernetes/kubernetes/issues/70264
* https://groups.google.com/forum/#!msg/kubernetes-sig-architecture/wCWiWf3Juzs/hXRVBH90CgAJ
* https://groups.google.com/forum/#!msg/kubernetes-dev/7vnijOMhLS0/1oRiNtigBgAJ
----
How to use klog
===============
- Replace imports for `github.com/golang/glog` with `k8s.io/klog`
- Use `klog.InitFlags(nil)` explicitly for initializing global flags as we no longer use `init()` method to register the flags
- You can now use `log_file` instead of `log_dir` for logging to a single file (See `examples/log_file/usage_log_file.go`)
- If you want to redirect everything logged using klog somewhere else (say syslog!), you can use `klog.SetOutput()` method and supply a `io.Writer`. (See `examples/set_output/usage_set_output.go`)
- For more logging conventions (See [Logging Conventions](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-instrumentation/logging.md))
**NOTE**: please use the newer go versions that support semantic import versioning in modules, ideally go 1.11.4 or greater.
### Coexisting with glog
This package can be used side by side with glog. [This example](examples/coexist_glog/coexist_glog.go) shows how to initialize and syncronize flags from the global `flag.CommandLine` FlagSet. In addition, the example makes use of stderr as combined output by setting `alsologtostderr` (or `logtostderr`) to `true`.

glog
====
Leveled execution logs for Go.
This is an efficient pure Go implementation of leveled logs in the
manner of the open source C++ package
https://github.com/google/glog
By binding methods to booleans it is possible to use the log package
without paying the expense of evaluating the arguments to the log.
Through the -vmodule flag, the package also provides fine-grained
control over logging at the file level.
The comment from glog.go introduces the ideas:
Package glog implements logging analogous to the Google-internal
C++ INFO/ERROR/V setup. It provides functions Info, Warning,
Error, Fatal, plus formatting variants such as Infof. It
also provides V-style logging controlled by the -v and
-vmodule=file=2 flags.
Basic examples:
glog.Info("Prepare to repel boarders")
glog.Fatalf("Initialization failed: %s", err)
See the documentation for the V function for an explanation
of these examples:
if glog.V(2) {
glog.Info("Starting transaction...")
}
glog.V(2).Infoln("Processed", nItems, "elements")
The repository contains an open source version of the log package
used inside Google. The master copy of the source lives inside
Google, not here. The code in this repo is for export only and is not itself
under development. Feature requests will be ignored.
Send bug reports to golang-nuts@googlegroups.com.
