# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [1.10.0] - 2022-08-11
### Added
- Add `atomic.Float32` type for atomic operations on `float32`.
- Add `CompareAndSwap` and `Swap` methods to `atomic.String`, `atomic.Error`,
and `atomic.Value`.
- Add generic `atomic.Pointer[T]` type for atomic operations on pointers of any
type. This is present only for Go 1.18 or higher, and is a drop-in for
replacement for the standard library's `sync/atomic.Pointer` type.
### Changed
- Deprecate `CAS` methods on all types in favor of corresponding
`CompareAndSwap` methods.
Thanks to @eNV25 and @icpd for their contributions to this release.

# atomic [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov] [![Go Report Card][reportcard-img]][reportcard]
Simple wrappers for primitive types to enforce atomic access.
## Installation
```shell
$ go get -u go.uber.org/atomic@v1
```
### Legacy Import Path
As of v1.5.0, the import path `go.uber.org/atomic` is the only supported way
of using this package. If you are using Go modules, this package will fail to
compile with the legacy import path path `github.com/uber-go/atomic`.
We recommend migrating your code to the new import path but if you're unable
to do so, or if your dependencies are still using the old import path, you
will have to add a `replace` directive to your `go.mod` file downgrading the
legacy import path to an older version.
```
replace github.com/uber-go/atomic => github.com/uber-go/atomic v1.4.0
```
You can do so automatically by running the following command.
```shell
$ go mod edit -replace github.com/uber-go/atomic=github.com/uber-go/atomic@v1.4.0
```
## Usage
The standard library's `sync/atomic` is powerful, but it's easy to forget which
variables must be accessed atomically. `go.uber.org/atomic` preserves all the
functionality of the standard library, but wraps the primitive types to
provide a safer, more convenient API.
```go
var atom atomic.Uint32
atom.Store(42)
atom.Sub(2)
atom.CAS(40, 11)
```
See the [documentation][doc] for a complete API specification.
## Development Status
Stable.

// Package multierr allows combining one or more errors together.
//
// Overview
//
// Errors can be combined with the use of the Combine function.
//
// multierr.Combine(
// reader.Close(),
// writer.Close(),
// conn.Close(),
// )
//
// If only two errors are being combined, the Append function may be used
// instead.
//
// err = multierr.Append(reader.Close(), writer.Close())
//
// The underlying list of errors for a returned error object may be retrieved
// with the Errors function.
//
// errors := multierr.Errors(err)
// if len(errors) > 0 {
// fmt.Println("The following errors occurred:", errors)
// }
//
// Appending from a loop
//
// You sometimes need to append into an error from a loop.
//
// var err error
// for _, item := range items {
// err = multierr.Append(err, process(item))
// }
//
// Cases like this may require knowledge of whether an individual instance
// failed. This usually requires introduction of a new variable.
//
// var err error
// for _, item := range items {
// if perr := process(item); perr != nil {
// log.Warn("skipping item", item)
// err = multierr.Append(err, perr)
// }
// }
//
// multierr includes AppendInto to simplify cases like this.
//
// var err error
// for _, item := range items {
// if multierr.AppendInto(&err, process(item)) {
// log.Warn("skipping item", item)
// }
// }
//
// This will append the error into the err variable, and return true if that
// individual error was non-nil.
//
// See AppendInto for more information.
//
// Deferred Functions
//
// Go makes it possible to modify the return value of a function in a defer
// block if the function was using named returns. This makes it possible to
// record resource cleanup failures from deferred blocks.
//
// func sendRequest(req Request) (err error) {
// conn, err := openConnection()
// if err != nil {
// return err
// }
// defer func() {
// err = multierr.Append(err, conn.Close())
// }()
// // ...
// }
//
// multierr provides the Invoker type and AppendInvoke function to make cases
// like the above simpler and obviate the need for a closure. The following is
// roughly equivalent to the example above.
//
// func sendRequest(req Request) (err error) {
// conn, err := openConnection()
// if err != nil {
// return err
// }
// defer multierr.AppendInvoke(&err, multierr.Close(conn))
// // ...
// }
//
// See AppendInvoke and Invoker for more information.
//
// Advanced Usage
//
// Errors returned by Combine and Append MAY implement the following
// interface.
//
// type errorGroup interface {
// // Returns a slice containing the underlying list of errors.
// //
// // This slice MUST NOT be modified by the caller.
// Errors() []error
// }
//
// Note that if you need access to list of errors behind a multierr error, you
// should prefer using the Errors function. That said, if you need cheap
// read-only access to the underlying errors slice, you can attempt to cast
// the error to this interface. You MUST handle the failure case gracefully
// because errors returned by Combine and Append are not guaranteed to
// implement this interface.
//
// var errors []error
// group, ok := err.(errorGroup)
// if ok {
// errors = group.Errors()
// } else {
// errors = []error{err}
// }

// return processReader(f)
// }
//
// In this example, multierr.Close will construct the Invoker right away, but
// defer the invocation of f.Close until the function returns.
//
// defer multierr.AppendInvoke(&err, multierr.Close(f))
func Close(closer io.Closer) Invoker {
return Invoke(closer.Close)
}
// AppendInvoke appends the result of calling the given Invoker into the
// provided error pointer. Use it with named returns to safely defer
// invocation of fallible operations until a function returns, and capture the
// resulting errors.
//
// func doSomething(...) (err error) {
// // ...
// f, err := openFile(..)
// if err != nil {
// return err
// }
//
// // multierr will call f.Close() when this function returns and
// // if the operation fails, its append its error into the
// // returned error.
// defer multierr.AppendInvoke(&err, multierr.Close(f))
//
// scanner := bufio.NewScanner(f)
// // Similarly, this scheduled scanner.Err to be called and
// // inspected when the function returns and append its error
// // into the returned error.
// defer multierr.AppendInvoke(&err, multierr.Invoke(scanner.Err))
//
// // ...
// }
//
// Without defer, AppendInvoke behaves exactly like AppendInto.
//
// err := // ...
// multierr.AppendInvoke(&err, mutltierr.Invoke(foo))
//
// // ...is roughly equivalent to...
//
// err := // ...
// multierr.AppendInto(&err, foo())
//
// The advantage of the indirection introduced by Invoker is to make it easy
// to defer the invocation of a function. Without this indirection, the
// invoked function will be evaluated at the time of the defer block rather
// than when the function returns.
//
// // BAD: This is likely not what the caller intended. This will evaluate
// // foo() right away and append its result into the error when the
// // function returns.
// defer multierr.AppendInto(&err, foo())
//
// // GOOD: This will defer invocation of foo unutil the function returns.
// defer multierr.AppendInvoke(&err, multierr.Invoke(foo))
//
// multierr provides a few Invoker implementations out of the box for
// convenience. See Invoker for more information.
func AppendInvoke(into *error, invoker Invoker) {
AppendInto(into, invoker.Invoke())
}

# :zap: zap [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
Blazing fast, structured, leveled logging in Go.
## Installation
`go get -u go.uber.org/zap`
Note that zap only supports the two most recent minor versions of Go.
## Quick Start
In contexts where performance is nice, but not critical, use the
`SugaredLogger`. It's 4-10x faster than other structured logging
packages and includes both structured and `printf`-style APIs.
```go
logger, _ := zap.NewProduction()
defer logger.Sync() // flushes buffer, if any
sugar := logger.Sugar()
sugar.Infow("failed to fetch URL",
// Structured context as loosely typed key-value pairs.
"url", url,
"attempt", 3,
"backoff", time.Second,
)
sugar.Infof("Failed to fetch URL: %s", url)
```
When performance and type safety are critical, use the `Logger`. It's even
faster than the `SugaredLogger` and allocates far less, but it only supports
structured logging.
```go
logger, _ := zap.NewProduction()
defer logger.Sync()
logger.Info("failed to fetch URL",
// Structured context as strongly typed Field values.
zap.String("url", url),
zap.Int("attempt", 3),
zap.Duration("backoff", time.Second),
)
```
See the [documentation][doc] and [FAQ](FAQ.md) for more details.
## Performance
For applications that log in the hot path, reflection-based serialization and
string formatting are prohibitively expensive &mdash; they're CPU-intensive
and make many small allocations. Put differently, using `encoding/json` and
`fmt.Fprintf` to log tons of `interface{}`s makes your application slow.
Zap takes a different approach. It includes a reflection-free, zero-allocation
JSON encoder, and the base `Logger` strives to avoid serialization overhead
and allocations wherever possible. By building the high-level `SugaredLogger`
on that foundation, zap lets users *choose* when they need to count every
allocation and when they'd prefer a more familiar, loosely typed API.
As measured by its own [benchmarking suite][], not only is zap more performant
than comparable structured logging packages &mdash; it's also faster than the
standard library. Like all benchmarks, take these with a grain of salt.<sup
id="anchor-versions">[1](#footnote-versions)</sup>
Log a message and 10 fields:
{{.BenchmarkAddingFields}}
Log a message with a logger that already has 10 fields of context:
{{.BenchmarkAccumulatedContext}}
Log a static string, without any context or `printf`-style templating:
{{.BenchmarkWithoutFields}}
## Development Status: Stable
All APIs are finalized, and no breaking changes will be made in the 1.x series
of releases. Users of semver-aware dependency management systems should pin
zap to `^1`.
## Contributing
We encourage and support an active, healthy community of contributors &mdash;
including you! Details are in the [contribution guide](CONTRIBUTING.md) and
the [code of conduct](CODE_OF_CONDUCT.md). The zap maintainers keep an eye on

# Changelog
All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
## 1.23.0 (24 Aug 2022)
Enhancements:
* [#1147][]: Add a `zapcore.LevelOf` function to determine the level of a
`LevelEnabler` or `Core`.
* [#1155][]: Add `zap.Stringers` field constructor to log arrays of objects
that implement `String() string`.
[#1147]: https://github.com/uber-go/zap/pull/1147
[#1155]: https://github.com/uber-go/zap/pull/1155
## 1.22.0 (8 Aug 2022)
Enhancements:
* [#1071][]: Add `zap.Objects` and `zap.ObjectValues` field constructors to log
arrays of objects. With these two constructors, you don't need to implement
`zapcore.ArrayMarshaler` for use with `zap.Array` if those objects implement
`zapcore.ObjectMarshaler`.
* [#1079][]: Add `SugaredLogger.WithOptions` to build a copy of an existing
`SugaredLogger` with the provided options applied.
* [#1080][]: Add `*ln` variants to `SugaredLogger` for each log level.
These functions provide a string joining behavior similar to `fmt.Println`.
* [#1088][]: Add `zap.WithFatalHook` option to control the behavior of the
logger for `Fatal`-level log entries. This defaults to exiting the program.
* [#1108][]: Add a `zap.Must` function that you can use with `NewProduction` or
`NewDevelopment` to panic if the system was unable to build the logger.
* [#1118][]: Add a `Logger.Log` method that allows specifying the log level for
a statement dynamically.
Thanks to @cardil, @craigpastro, @sashamelentyev, @shota3506, and @zhupeijun
for their contributions to this release.

* [#835][]: Fix panic in JSON encoder when encoding times or durations
without specifying a time or duration encoder.
* [#843][]: Honor CallerSkip when taking stack traces.
* [#862][]: Fix the default file permissions to use `0666` and rely on the umask instead.
* [#854][]: Encode `<nil>` for nil `Stringer` instead of a panic error log.
Enhancements:
* [#629][]: Added `zapcore.TimeEncoderOfLayout` to easily create time encoders
for custom layouts.
* [#697][]: Added support for a configurable delimiter in the console encoder.
* [#852][]: Optimize console encoder by pooling the underlying JSON encoder.
* [#844][]: Add ability to include the calling function as part of logs.
* [#843][]: Add `StackSkip` for including truncated stacks as a field.

Thanks to @SteelPhase, @tmshn, @lixingwang, @wyxloading, @moul, @segevfiner, @andy-retailnext and @jcorbin for their contributions to this release.
## 1.15.0 (23 Apr 2020)
Bugfixes:
* [#804][]: Fix handling of `Time` values out of `UnixNano` range.
* [#812][]: Fix `IncreaseLevel` being reset after a call to `With`.
Enhancements:
* [#806][]: Add `WithCaller` option to supersede the `AddCaller` option. This
allows disabling annotation of log entries with caller information if
previously enabled with `AddCaller`.
* [#813][]: Deprecate `NewSampler` constructor in favor of
`NewSamplerWithOptions` which supports a `SamplerHook` option. This option
adds support for monitoring sampling decisions through a hook.
Thanks to @danielbprice for their contributions to this release.
## 1.14.1 (14 Mar 2020)
Bugfixes:
* [#791][]: Fix panic on attempting to build a logger with an invalid Config.
* [#795][]: Vendoring Zap with `go mod vendor` no longer includes Zap's
development-time dependencies.
* [#799][]: Fix issue introduced in 1.14.0 that caused invalid JSON output to
be generated for arrays of `time.Time` objects when using string-based time
formats.
Thanks to @YashishDua for their contributions to this release.
## 1.14.0 (20 Feb 2020)
Enhancements:
* [#771][]: Optimize calls for disabled log levels.
* [#773][]: Add millisecond duration encoder.

to specify the level of the logged messages.
## v1.6.0 (30 Aug 2017)
Enhancements:
* [#491][]: Omit zap stack frames from stacktraces.
* [#490][]: Add a `ContextMap` method to observer logs for simpler
field validation in tests.
## v1.5.0 (22 Jul 2017)
Enhancements:
* [#460][] and [#470][]: Support errors produced by `go.uber.org/multierr`.
* [#465][]: Support user-supplied encoders for logger names.
Bugfixes:
* [#477][]: Fix a bug that incorrectly truncated deep stacktraces.
Thanks to @richard-tunein and @pavius for their contributions to this release.
## v1.4.1 (08 Jun 2017)
This release fixes two bugs.
Bugfixes:
* [#435][]: Support a variety of case conventions when unmarshaling levels.
* [#444][]: Fix a panic in the observer.
## v1.4.0 (12 May 2017)
This release adds a few small features and is fully backward-compatible.
Enhancements:
* [#424][]: Add a `LineEnding` field to `EncoderConfig`, allowing users to
override the Unix-style default.
* [#425][]: Preserve time zones when logging times.
* [#431][]: Make `zap.AtomicLevel` implement `fmt.Stringer`, which makes a
variety of operations a bit simpler.
## v1.3.0 (25 Apr 2017)
This release adds an enhancement to zap's testing helpers as well as the
ability to marshal an AtomicLevel. It is fully backward-compatible.
Enhancements:
* [#415][]: Add a substring-filtering helper to zap's observer. This is
particularly useful when testing the `SugaredLogger`.
* [#416][]: Make `AtomicLevel` implement `encoding.TextMarshaler`.
## v1.2.0 (13 Apr 2017)
This release adds a gRPC compatibility wrapper. It is fully backward-compatible.
Enhancements:
* [#402][]: Add a `zapgrpc` package that wraps zap's Logger and implements
`grpclog.Logger`.
## v1.1.0 (31 Mar 2017)
This release fixes two bugs and adds some enhancements to zap's testing helpers.
It is fully backward-compatible.
Bugfixes:
* [#385][]: Fix caller path trimming on Windows.
* [#396][]: Fix a panic when attempting to use non-existent directories with
zap's configuration struct.
Enhancements:
* [#386][]: Add filtering helpers to zaptest's observing logger.
Thanks to @moitias for contributing to this release.
## v1.0.0 (14 Mar 2017)
This is zap's first stable release. All exported APIs are now final, and no
further breaking changes will be made in the 1.x release series. Anyone using a
semver-aware dependency manager should now pin to `^1`.
Breaking changes:
* [#366][]: Add byte-oriented APIs to encoders to log UTF-8 encoded text without
casting from `[]byte` to `string`.
* [#364][]: To support buffering outputs, add `Sync` methods to `zapcore.Core`,
`zap.Logger`, and `zap.SugaredLogger`.
* [#371][]: Rename the `testutils` package to `zaptest`, which is less likely to
clash with other testing helpers.
Bugfixes:
* [#362][]: Make the ISO8601 time formatters fixed-width, which is friendlier
for tab-separated console output.
* [#369][]: Remove the automatic locks in `zapcore.NewCore`, which allows zap to
work with concurrency-safe `WriteSyncer` implementations.
* [#347][]: Stop reporting errors when trying to `fsync` standard out on Linux
systems.
* [#373][]: Report the correct caller from zap's standard library
interoperability wrappers.
Enhancements:
* [#348][]: Add a registry allowing third-party encodings to work with zap's
built-in `Config`.
* [#327][]: Make the representation of logger callers configurable (like times,
levels, and durations).
* [#376][]: Allow third-party encoders to use their own buffer pools, which
removes the last performance advantage that zap's encoders have over plugins.
* [#346][]: Add `CombineWriteSyncers`, a convenience function to tee multiple
`WriteSyncer`s and lock the result.
* [#365][]: Make zap's stacktraces compatible with mid-stack inlining (coming in
Go 1.9).
* [#372][]: Export zap's observing logger as `zaptest/observer`. This makes it
easier for particularly punctilious users to unit test their application's
logging.
Thanks to @suyash, @htrendev, @flisky, @Ulexus, and @skipor for their
contributions to this release.
## v1.0.0-rc.3 (7 Mar 2017)
This is the third release candidate for zap's stable release. There are no
breaking changes.
Bugfixes:
* [#339][]: Byte slices passed to `zap.Any` are now correctly treated as binary blobs
rather than `[]uint8`.
Enhancements:
* [#307][]: Users can opt into colored output for log levels.
* [#353][]: In addition to hijacking the output of the standard library's
package-global logging functions, users can now construct a zap-backed
`log.Logger` instance.
* [#311][]: Frames from common runtime functions and some of zap's internal
machinery are now omitted from stacktraces.
Thanks to @ansel1 and @suyash for their contributions to this release.
## v1.0.0-rc.2 (21 Feb 2017)
This is the second release candidate for zap's stable release. It includes two
breaking changes.
Breaking changes:
* [#316][]: Zap's global loggers are now fully concurrency-safe
(previously, users had to ensure that `ReplaceGlobals` was called before the
loggers were in use). However, they must now be accessed via the `L()` and
`S()` functions. Users can update their projects with
```
gofmt -r "zap.L -> zap.L()" -w .
gofmt -r "zap.S -> zap.S()" -w .
```
* [#309][] and [#317][]: RC1 was mistakenly shipped with invalid
JSON and YAML struct tags on all config structs. This release fixes the tags
and adds static analysis to prevent similar bugs in the future.
Bugfixes:
* [#321][]: Redirecting the standard library's `log` output now
correctly reports the logger's caller.
Enhancements:
* [#325][] and [#333][]: Zap now transparently supports non-standard, rich
errors like those produced by `github.com/pkg/errors`.
* [#326][]: Though `New(nil)` continues to return a no-op logger, `NewNop()` is
now preferred. Users can update their projects with `gofmt -r 'zap.New(nil) ->
zap.NewNop()' -w .`.
* [#300][]: Incorrectly importing zap as `github.com/uber-go/zap` now returns a
more informative error.
Thanks to @skipor and @chapsuk for their contributions to this release.
## v1.0.0-rc.1 (14 Feb 2017)
This is the first release candidate for zap's stable release. There are multiple
breaking changes and improvements from the pre-release version. Most notably:
* **Zap's import path is now "go.uber.org/zap"** &mdash; all users will
need to update their code.
* User-facing types and functions remain in the `zap` package. Code relevant
largely to extension authors is now in the `zapcore` package.
* The `zapcore.Core` type makes it easy for third-party packages to use zap's
internals but provide a different user-facing API.
* `Logger` is now a concrete type instead of an interface.
* A less verbose (though slower) logging API is included by default.
* Package-global loggers `L` and `S` are included.
* A human-friendly console encoder is included.
* A declarative config struct allows common logger configurations to be managed
as configuration instead of code.
* Sampling is more accurate, and doesn't depend on the standard library's shared
timer heap.
## v0.1.0-beta.1 (6 Feb 2017)
This is a minor version, tagged to allow users to pin to the pre-1.0 APIs and
upgrade at their leisure. Since this is the first tagged release, there are no
backward compatibility concerns and all functionality is new.
Early zap adopters should pin to the 0.1.x minor version until they're ready to
upgrade to the upcoming stable release.

# Frequently Asked Questions
## Design
### Why spend so much effort on logger performance?
Of course, most applications won't notice the impact of a slow logger: they
already take tens or hundreds of milliseconds for each operation, so an extra
millisecond doesn't matter.
On the other hand, why *not* make structured logging fast? The `SugaredLogger`
isn't any harder to use than other logging packages, and the `Logger` makes
structured logging possible in performance-sensitive contexts. Across a fleet
of Go microservices, making each application even slightly more efficient adds
up quickly.
### Why aren't `Logger` and `SugaredLogger` interfaces?
Unlike the familiar `io.Writer` and `http.Handler`, `Logger` and
`SugaredLogger` interfaces would include *many* methods. As [Rob Pike points
out][go-proverbs], "The bigger the interface, the weaker the abstraction."
Interfaces are also rigid &mdash; *any* change requires releasing a new major
version, since it breaks all third-party implementations.
Making the `Logger` and `SugaredLogger` concrete types doesn't sacrifice much
abstraction, and it lets us add methods without introducing breaking changes.
Your applications should define and depend upon an interface that includes
just the methods you use.
### Why are some of my logs missing?
Logs are dropped intentionally by zap when sampling is enabled. The production
configuration (as returned by `NewProductionConfig()` enables sampling which will
cause repeated logs within a second to be sampled. See more details on why sampling
is enabled in [Why sample application logs](https://github.com/uber-go/zap/blob/master/FAQ.md#why-sample-application-logs).
### Why sample application logs?
Applications often experience runs of errors, either because of a bug or
because of a misbehaving user. Logging errors is usually a good idea, but it
can easily make this bad situation worse: not only is your application coping
with a flood of errors, it's also spending extra CPU cycles and I/O logging
those errors. Since writes are typically serialized, logging limits throughput
when you need it most.
Sampling fixes this problem by dropping repetitive log entries. Under normal
conditions, your application writes out every entry. When similar entries are
logged hundreds or thousands of times each second, though, zap begins dropping
duplicates to preserve throughput.
### Why do the structured logging APIs take a message in addition to fields?
Subjectively, we find it helpful to accompany structured context with a brief
description. This isn't critical during development, but it makes debugging
and operating unfamiliar systems much easier.
More concretely, zap's sampling algorithm uses the message to identify
duplicate entries. In our experience, this is a practical middle ground
between random sampling (which often drops the exact entry that you need while
debugging) and hashing the complete entry (which is prohibitively expensive).
### Why include package-global loggers?
Since so many other logging packages include a global logger, many
applications aren't designed to accept loggers as explicit parameters.
Changing function signatures is often a breaking change, so zap includes
global loggers to simplify migration.
Avoid them where possible.
### Why include dedicated Panic and Fatal log levels?
In general, application code should handle errors gracefully instead of using
`panic` or `os.Exit`. However, every rule has exceptions, and it's common to
crash when an error is truly unrecoverable. To avoid losing any information
&mdash; especially the reason for the crash &mdash; the logger must flush any
buffered entries before the process exits.
Zap makes this easy by offering `Panic` and `Fatal` logging methods that
automatically flush before exiting. Of course, this doesn't guarantee that
logs will never be lost, but it eliminates a common error.
See the discussion in uber-go/zap#207 for more details.
### What's `DPanic`?
`DPanic` stands for "panic in development." In development, it logs at
`PanicLevel`; otherwise, it logs at `ErrorLevel`. `DPanic` makes it easier to
catch errors that are theoretically possible, but shouldn't actually happen,
*without* crashing in production.
If you've ever written code like this, you need `DPanic`:
```go
if err != nil {
panic(fmt.Sprintf("shouldn't ever get here: %v", err))
}
```
## Installation
### What does the error `expects import "go.uber.org/zap"` mean?
Either zap was installed incorrectly or you're referencing the wrong package
name in your code.
Zap's source code happens to be hosted on GitHub, but the [import
path][import-path] is `go.uber.org/zap`. This gives us, the project
maintainers, the freedom to move the source code if necessary. However, it
means that you need to take a little care when installing and using the
package.
If you follow two simple rules, everything should work: install zap with `go
get -u go.uber.org/zap`, and always import it in your code with `import
"go.uber.org/zap"`. Your code shouldn't contain *any* references to
`github.com/uber-go/zap`.
## Usage
### Does zap support log rotation?
Zap doesn't natively support rotating log files, since we prefer to leave this
to an external program like `logrotate`.
However, it's easy to integrate a log rotation package like
[`gopkg.in/natefinch/lumberjack.v2`][lumberjack] as a `zapcore.WriteSyncer`.
```go
// lumberjack.Logger is already safe for concurrent use, so we don't need to
// lock it.
w := zapcore.AddSync(&lumberjack.Logger{
Filename: "/var/log/myapp/foo.log",
MaxSize: 500, // megabytes
MaxBackups: 3,
MaxAge: 28, // days
})
core := zapcore.NewCore(
zapcore.NewJSONEncoder(zap.NewProductionEncoderConfig()),
w,
zap.InfoLevel,
)
logger := zap.New(core)
```
## Extensions
We'd love to support every logging need within zap itself, but we're only
familiar with a handful of log ingestion systems, flag-parsing packages, and
the like. Rather than merging code that we can't effectively debug and
support, we'd rather grow an ecosystem of zap extensions.
We're aware of the following extensions, but haven't used them ourselves:
| Package | Integration |
| --- | --- |
| `github.com/tchap/zapext` | Sentry, syslog |
| `github.com/fgrosse/zaptest` | Ginkgo |
| `github.com/blendle/zapdriver` | Stackdriver |

| `github.com/moul/zapfilter` | Advanced filtering rules |

# :zap: zap [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
Blazing fast, structured, leveled logging in Go.
## Installation
`go get -u go.uber.org/zap`
Note that zap only supports the two most recent minor versions of Go.
## Quick Start
In contexts where performance is nice, but not critical, use the
`SugaredLogger`. It's 4-10x faster than other structured logging
packages and includes both structured and `printf`-style APIs.
```go
logger, _ := zap.NewProduction()
defer logger.Sync() // flushes buffer, if any
sugar := logger.Sugar()
sugar.Infow("failed to fetch URL",
// Structured context as loosely typed key-value pairs.
"url", url,
"attempt", 3,
"backoff", time.Second,
)
sugar.Infof("Failed to fetch URL: %s", url)
```
When performance and type safety are critical, use the `Logger`. It's even
faster than the `SugaredLogger` and allocates far less, but it only supports
structured logging.
```go
logger, _ := zap.NewProduction()
defer logger.Sync()
logger.Info("failed to fetch URL",
// Structured context as strongly typed Field values.
zap.String("url", url),
zap.Int("attempt", 3),
zap.Duration("backoff", time.Second),
)
```
See the [documentation][doc] and [FAQ](FAQ.md) for more details.
## Performance
For applications that log in the hot path, reflection-based serialization and
string formatting are prohibitively expensive &mdash; they're CPU-intensive
and make many small allocations. Put differently, using `encoding/json` and
`fmt.Fprintf` to log tons of `interface{}`s makes your application slow.
Zap takes a different approach. It includes a reflection-free, zero-allocation
JSON encoder, and the base `Logger` strives to avoid serialization overhead
and allocations wherever possible. By building the high-level `SugaredLogger`
on that foundation, zap lets users _choose_ when they need to count every
allocation and when they'd prefer a more familiar, loosely typed API.
As measured by its own [benchmarking suite][], not only is zap more performant
than comparable structured logging packages &mdash; it's also faster than the
standard library. Like all benchmarks, take these with a grain of salt.<sup

## Development Status: Stable
All APIs are finalized, and no breaking changes will be made in the 1.x series
of releases. Users of semver-aware dependency management systems should pin
zap to `^1`.

// Package zap provides fast, structured, leveled logging.
//
// For applications that log in the hot path, reflection-based serialization
// and string formatting are prohibitively expensive - they're CPU-intensive
// and make many small allocations. Put differently, using json.Marshal and
// fmt.Fprintf to log tons of interface{} makes your application slow.
//
// Zap takes a different approach. It includes a reflection-free,
// zero-allocation JSON encoder, and the base Logger strives to avoid
// serialization overhead and allocations wherever possible. By building the
// high-level SugaredLogger on that foundation, zap lets users choose when
// they need to count every allocation and when they'd prefer a more familiar,
// loosely typed API.
//
// # Choosing a Logger
//
// In contexts where performance is nice, but not critical, use the
// SugaredLogger. It's 4-10x faster than other structured logging packages and
// supports both structured and printf-style logging. Like log15 and go-kit,
// the SugaredLogger's structured logging APIs are loosely typed and accept a
// variadic number of key-value pairs. (For more advanced use cases, they also
// accept strongly typed fields - see the SugaredLogger.With documentation for
// details.)
//
// sugar := zap.NewExample().Sugar()
// defer sugar.Sync()
// sugar.Infow("failed to fetch URL",
// "url", "http://example.com",
// "attempt", 3,
// "backoff", time.Second,
// )
// sugar.Infof("failed to fetch URL: %s", "http://example.com")
//
// By default, loggers are unbuffered. However, since zap's low-level APIs
// allow buffering, calling Sync before letting your process exit is a good
// habit.
//
// In the rare contexts where every microsecond and every allocation matter,
// use the Logger. It's even faster than the SugaredLogger and allocates far
// less, but it only supports strongly-typed, structured logging.
//
// logger := zap.NewExample()
// defer logger.Sync()
// logger.Info("failed to fetch URL",
// zap.String("url", "http://example.com"),
// zap.Int("attempt", 3),
// zap.Duration("backoff", time.Second),
// )
//
// Choosing between the Logger and SugaredLogger doesn't need to be an
// application-wide decision: converting between the two is simple and
// inexpensive.
//
// logger := zap.NewExample()
// defer logger.Sync()
// sugar := logger.Sugar()
// plain := sugar.Desugar()
//
// # Configuring Zap
//
// The simplest way to build a Logger is to use zap's opinionated presets:
// NewExample, NewProduction, and NewDevelopment. These presets build a logger
// with a single function call:
//
// logger, err := zap.NewProduction()
// if err != nil {
// log.Fatalf("can't initialize zap logger: %v", err)
// }
// defer logger.Sync()
//
// Presets are fine for small projects, but larger projects and organizations
// naturally require a bit more customization. For most users, zap's Config
// struct strikes the right balance between flexibility and convenience. See
// the package-level BasicConfiguration example for sample code.
//
// More unusual configurations (splitting output between files, sending logs
// to a message queue, etc.) are possible, but require direct use of
// go.uber.org/zap/zapcore. See the package-level AdvancedConfiguration
// example for sample code.
//
// # Extending Zap
//
// The zap package itself is a relatively thin wrapper around the interfaces
// in go.uber.org/zap/zapcore. Extending zap to support a new encoding (e.g.,
// BSON), a new log sink (e.g., Kafka), or something more exotic (perhaps an
// exception aggregation service, like Sentry or Rollbar) typically requires
// implementing the zapcore.Encoder, zapcore.WriteSyncer, or zapcore.Core
// interfaces. See the zapcore documentation for details.
//
// Similarly, package authors can use the high-performance Encoder and Core
// implementations in the zapcore package to build their own loggers.
//
// # Frequently Asked Questions
//
// An FAQ covering everything from installation errors to design decisions is
// available at https://github.com/uber-go/zap/blob/master/FAQ.md.
