+# UUID package for Go language
+
+[](https://travis-ci.org/satori/go.uuid)
+[](https://coveralls.io/github/satori/go.uuid)
+[](http://godoc.org/github.com/satori/go.uuid)
+
+This package provides pure Go implementation of Universally Unique Identifier (UUID). Supported both creation and parsing of UUIDs.
+
+With 100% test coverage and benchmarks out of box.
+
+Supported versions:
+* Version 1, based on timestamp and MAC address (RFC 4122)
+* Version 2, based on timestamp, MAC address and POSIX UID/GID (DCE 1.1)
+* Version 3, based on MD5 hashing (RFC 4122)
+* Version 4, based on random numbers (RFC 4122)
+* Version 5, based on SHA-1 hashing (RFC 4122)
+
+## Installation
+
+Use the `go` command:
+
+ $ go get github.com/satori/go.uuid
+
+## Requirements
+
+UUID package requires Go >= 1.2.
+
+## Example
+
+```go
+package main
+
+import (
+ "fmt"
+ "github.com/satori/go.uuid"
+)
+
+func main() {
+ // Creating UUID Version 4
+ u1 := uuid.NewV4()
+ fmt.Printf("UUIDv4: %s\n", u1)
+
+ // Parsing UUID from string input
+ u2, err := uuid.FromString("6ba7b810-9dad-11d1-80b4-00c04fd430c8")
+ if err != nil {
+ fmt.Printf("Something gone wrong: %s", err)
+ }
+ fmt.Printf("Successfully parsed: %s", u2)
+}
+```
+

+get json values quickly
+
+GJSON is a Go package that provides a [fast](#performance) and [simple](#get-a-value) way to get values from a json document.
+It has features such as [one line retrieval](#get-a-value), [dot notation paths](#path-syntax), [iteration](#iterate-through-an-object-or-array), and [parsing json lines](#json-lines).
+
+Also check out [SJSON](https://github.com/tidwall/sjson) for modifying json, and the [JJ](https://github.com/tidwall/jj) command line tool.
+
+Getting Started
+===============
+
+## Installing
+
+To start using GJSON, install Go and run `go get`:
+
+```sh
+$ go get -u github.com/tidwall/gjson
+```
+
+This will retrieve the library.
+
+## Get a value
+Get searches json for the specified path. A path is in dot syntax, such as "name.last" or "age". When the value is found it's returned immediately.
+
+```go
+package main
+
+import "github.com/tidwall/gjson"
+
+const json = `{"name":{"first":"Janet","last":"Prichard"},"age":47}`
+
+func main() {
+ value := gjson.Get(json, "name.last")
+ println(value.String())
+}
+```
+
+This will print:
+
+```
+Prichard
+```
+*There's also the [GetMany](#get-multiple-values-at-once) function to get multiple values at once, and [GetBytes](#working-with-bytes) for working with JSON byte slices.*
+
+## Path Syntax
+
+Below is a quick overview of the path syntax, for more complete information please
+check out [GJSON Syntax](SYNTAX.md).
+
+A path is a series of keys separated by a dot.
+A key may contain special wildcard characters '\*' and '?'.
+To access an array value use the index as the key.
+To get the number of elements in an array or to access a child path, use the '#' character.
+The dot and wildcard characters can be escaped with '\\'.
+
+```json
+{
+ "name": {"first": "Tom", "last": "Anderson"},
+ "age":37,
+ "children": ["Sara","Alex","Jack"],
+ "fav.movie": "Deer Hunter",
+ "friends": [
+ {"first": "Dale", "last": "Murphy", "age": 44},
+ {"first": "Roger", "last": "Craig", "age": 68},
+ {"first": "Jane", "last": "Murphy", "age": 47}
+ ]
+}
+```
+```
+"name.last" >> "Anderson"
+"age" >> 37
+"children" >> ["Sara","Alex","Jack"]
+"children.#" >> 3
+"children.1" >> "Alex"
+"child*.2" >> "Jack"
+"c?ildren.0" >> "Sara"
+"fav\.movie" >> "Deer Hunter"
+"friends.#.first" >> ["Dale","Roger","Jane"]
+"friends.1.last" >> "Craig"
+```
+
+You can also query an array for the first match by using `#[...]`, or find all matches with `#[...]#`.
+Queries support the `==`, `!=`, `<`, `<=`, `>`, `>=` comparison operators and the simple pattern matching `%` (like) and `!%` (not like) operators.
+
+```
+friends.#[last=="Murphy"].first >> "Dale"
+friends.#[last=="Murphy"]#.first >> ["Dale","Jane"]
+friends.#[age>45]#.last >> ["Craig","Murphy"]
+friends.#[first%"D*"].last >> "Murphy"
+friends.#[first!%"D*"].last >> "Craig"
+```
+
+## Result Type
+
+GJSON supports the json types `string`, `number`, `bool`, and `null`.
+Arrays and Objects are returned as their raw json types.
+
+The `Result` type holds one of these:
+
+```
+bool, for JSON booleans
+float64, for JSON numbers
+string, for JSON string literals
+nil, for JSON null
+```
+
+To directly access the value:
+
+```go
+result.Type // can be String, Number, True, False, Null, or JSON
+result.Str // holds the string
+result.Num // holds the float64 number
+result.Raw // holds the raw json
+result.Index // index of raw value in original json, zero means index unknown
+```
+
+There are a variety of handy functions that work on a result:
+
+```go
+result.Exists() bool
+result.Value() interface{}
+result.Int() int64
+result.Uint() uint64
+result.Float() float64
+result.String() string
+result.Bool() bool
+result.Time() time.Time
+result.Array() []gjson.Result
+result.Map() map[string]gjson.Result
+result.Get(path string) Result
+result.ForEach(iterator func(key, value Result) bool)
+result.Less(token Result, caseSensitive bool) bool
+```
+
+The `result.Value()` function returns an `interface{}` which requires type assertion and is one of the following Go types:
+
+The `result.Array()` function returns back an array of values.
+If the result represents a non-existent value, then an empty array will be returned.
+If the result is not a JSON array, the return value will be an array containing one result.
+
+```go
+boolean >> bool
+number >> float64
+string >> string
+null >> nil
+array >> []interface{}
+object >> map[string]interface{}
+```
+
+### 64-bit integers
+
+The `result.Int()` and `result.Uint()` calls are capable of reading all 64 bits, allowing for large JSON integers.
+
+```go
+result.Int() int64 // -9223372036854775808 to 9223372036854775807
+result.Uint() int64 // 0 to 18446744073709551615
+```
+
+## Modifiers and path chaining
+
+New in version 1.2 is support for modifier functions and path chaining.
+
+A modifier is a path component that performs custom processing on the
+json.
+
+Multiple paths can be "chained" together using the pipe character.
+This is useful for getting results from a modified query.
+
+For example, using the built-in `@reverse` modifier on the above json document,
+we'll get `children` array and reverse the order:
+
+```
+"children|@reverse" >> ["Jack","Alex","Sara"]
+"children|@reverse|0" >> "Jack"
+```
+
+There are currently three built-in modifiers:
+
+- `@reverse`: Reverse an array or the members of an object.
+- `@ugly`: Remove all whitespace from a json document.
+- `@pretty`: Make the json document more human readable.
+
+### Modifier arguments
+
+A modifier may accept an optional argument. The argument can be a valid JSON
+document or just characters.
+
+For example, the `@pretty` modifier takes a json object as its argument.
+
+```
+@pretty:{"sortKeys":true}
+```
+
+Which makes the json pretty and orders all of its keys.
+
+```json
+{
+ "age":37,
+ "children": ["Sara","Alex","Jack"],
+ "fav.movie": "Deer Hunter",
+ "friends": [
+ {"age": 44, "first": "Dale", "last": "Murphy"},
+ {"age": 68, "first": "Roger", "last": "Craig"},
+ {"age": 47, "first": "Jane", "last": "Murphy"}
+ ],
+ "name": {"first": "Tom", "last": "Anderson"}
+}
+```
+
+*The full list of `@pretty` options are `sortKeys`, `indent`, `prefix`, and `width`.
+Please see [Pretty Options](https://github.com/tidwall/pretty#customized-output) for more information.*
+
+### Custom modifiers
+
+You can also add custom modifiers.
+
+For example, here we create a modifier that makes the entire json document upper
+or lower case.
+
+```go
+gjson.AddModifier("case", func(json, arg string) string {
+ if arg == "upper" {
+ return strings.ToUpper(json)
+ }
+ if arg == "lower" {
+ return strings.ToLower(json)
+ }
+ return json
+})
+```
+
+```
+"children|@case:upper" >> ["SARA","ALEX","JACK"]
+"children|@case:lower|@reverse" >> ["jack","alex","sara"]
+```
+
+## JSON Lines
+
+There's support for [JSON Lines](http://jsonlines.org/) using the `..` prefix, which treats a multilined document as an array.
+
+For example:
+
+```
+{"name": "Gilbert", "age": 61}
+{"name": "Alexa", "age": 34}
+{"name": "May", "age": 57}
+{"name": "Deloise", "age": 44}
+```
+
+```
+..# >> 4
+..1 >> {"name": "Alexa", "age": 34}
+..3 >> {"name": "Deloise", "age": 44}
+..#.name >> ["Gilbert","Alexa","May","Deloise"]
+..#[name="May"].age >> 57
+```
+
+The `ForEachLines` function will iterate through JSON lines.
+
+```go
+gjson.ForEachLine(json, func(line gjson.Result) bool{
+ println(line.String())
+ return true
+})
+```
+
+## Get nested array values
+
+Suppose you want all the last names from the following json:
+
+```json
+{
+ "programmers": [
+ {
+ "firstName": "Janet",
+ "lastName": "McLaughlin",
+ }, {
+ "firstName": "Elliotte",
+ "lastName": "Hunter",
+ }, {
+ "firstName": "Jason",
+ "lastName": "Harold",
+ }
+ ]
+}
+```
+
+You would use the path "programmers.#.lastName" like such:
+
+```go
+result := gjson.Get(json, "programmers.#.lastName")
+for _, name := range result.Array() {
+ println(name.String())
+}
+```
+
+You can also query an object inside an array:
+
+```go
+name := gjson.Get(json, `programmers.#[lastName="Hunter"].firstName`)
+println(name.String()) // prints "Elliotte"
+```
+
+## Iterate through an object or array
+
+The `ForEach` function allows for quickly iterating through an object or array.
+The key and value are passed to the iterator function for objects.
+Only the value is passed for arrays.
+Returning `false` from an iterator will stop iteration.
+
+```go
+result := gjson.Get(json, "programmers")
+result.ForEach(func(key, value gjson.Result) bool {
+ println(value.String())
+ return true // keep iterating
+})
+```
+
+## Simple Parse and Get
+
+There's a `Parse(json)` function that will do a simple parse, and `result.Get(path)` that will search a result.
+
+For example, all of these will return the same result:
+
+```go
+gjson.Parse(json).Get("name").Get("last")
+gjson.Get(json, "name").Get("last")
+gjson.Get(json, "name.last")
+```
+
+## Check for the existence of a value
+
+Sometimes you just want to know if a value exists.
+
+```go
+value := gjson.Get(json, "name.last")
+if !value.Exists() {
+ println("no last name")
+} else {
+ println(value.String())
+}
+
+// Or as one step
+if gjson.Get(json, "name.last").Exists() {
+ println("has a last name")
+}
+```
+
+## Validate JSON
+
+The `Get*` and `Parse*` functions expects that the json is well-formed. Bad json will not panic, but it may return back unexpected results.
+
+If you are consuming JSON from an unpredictable source then you may want to validate prior to using GJSON.
+
+```go
+if !gjson.Valid(json) {
+ return errors.New("invalid json")
+}
+value := gjson.Get(json, "name.last")
+```
+
+## Unmarshal to a map
+
+To unmarshal to a `map[string]interface{}`:
+
+```go
+m, ok := gjson.Parse(json).Value().(map[string]interface{})
+if !ok {
+ // not a map
+}
+```
+
+## Working with Bytes
+
+If your JSON is contained in a `[]byte` slice, there's the [GetBytes](https://godoc.org/github.com/tidwall/gjson#GetBytes) function. This is preferred over `Get(string(data), path)`.
+
+```go
+var json []byte = ...
+result := gjson.GetBytes(json, path)
+```
+
+If you are using the `gjson.GetBytes(json, path)` function and you want to avoid converting `result.Raw` to a `[]byte`, then you can use this pattern:
+
+```go
+var json []byte = ...
+result := gjson.GetBytes(json, path)
+var raw []byte
+if result.Index > 0 {
+ raw = json[result.Index:result.Index+len(result.Raw)]
+} else {
+ raw = []byte(result.Raw)
+}
+```
+
+This is a best-effort no allocation sub slice of the original json. This method utilizes the `result.Index` field, which is the position of the raw data in the original json. It's possible that the value of `result.Index` equals zero, in which case the `result.Raw` is converted to a `[]byte`.
+
+## Get multiple values at once
+
+The `GetMany` function can be used to get multiple values at the same time.
+
+```go
+results := gjson.GetMany(json, "name.first", "name.last", "age")
+```
+
+The return value is a `[]Result`, which will always contain exactly the same number of items as the input paths.

+# GJSON Path Syntax
+
+A GJSON Path is a text string syntax that describes a search pattern for quickly retreiving values from a JSON payload.
+
+This document is designed to explain the structure of a GJSON Path through examples.
+
+- [Path structure](#path-structure)
+- [Basic](#basic)
+- [Wildcards](#wildcards)
+- [Escape Character](#escape-character)
+- [Arrays](#arrays)
+- [Queries](#queries)
+- [Dot vs Pipe](#dot-vs-pipe)
+- [Modifiers](#modifiers)
+
+The definitive implemenation is [github.com/tidwall/gjson](https://github.com/tidwall/gjson).
+
+
+## Path structure
+
+A GJSON Path is intended to be easily expressed as a series of components seperated by a `.` character.
+
+Along with `.` character, there are a few more that have special meaning, including `|`, `#`, `@`, `\`, `*`, and `?`.
+
+## Example
+
+Given this JSON
+
+```json
+{
+ "name": {"first": "Tom", "last": "Anderson"},
+ "age":37,
+ "children": ["Sara","Alex","Jack"],
+ "fav.movie": "Deer Hunter",
+ "friends": [
+ {"first": "Dale", "last": "Murphy", "age": 44},
+ {"first": "Roger", "last": "Craig", "age": 68},
+ {"first": "Jane", "last": "Murphy", "age": 47}
+ ]
+}
+```
+
+The following GJSON Paths evaluate to the accompanying values.
+
+### Basic
+
+In many cases you'll just want to retreive values by object name or array index.
+
+```go
+name.last "Anderson"
+name.first "Tom"
+age 37
+children ["Sara","Alex","Jack"]
+children.0 "Sara"
+children.1 "Alex"
+friends.1 {"first": "Roger", "last": "Craig", "age": 68}
+friends.1.first "Roger"
+```
+
+### Wildcards
+
+A key may contain the special wildcard characters `*` and `?`.
+The `*` will match on any zero+ characters, and `?` matches on any one character.
+
+```go
+child*.2 "Jack"
+c?ildren.0 "Sara"
+```
+
+### Escape character
+
+Special purpose characters, such as `.`, `*`, and `?` can be escaped with `\`.
+
+```go
+fav\.movie "Deer Hunter"
+```
+
+
+### Arrays
+
+The `#` character allows for digging into JSON Arrays.
+
+To get the length of an array you'll just use the `#` all by itself.
+
+```go
+friends.# 3
+friends.#.age [44,68,47]
+```
+
+### Queries
+
+You can also query an array for the first match by using `#[...]`, or find all matches with `#[...]#`.
+Queries support the `==`, `!=`, `<`, `<=`, `>`, `>=` comparison operators,
+and the simple pattern matching `%` (like) and `!%` (not like) operators.
+
+```go
+friends.#[last=="Murphy"].first "Dale"
+friends.#[last=="Murphy"]#.first ["Dale","Jane"]
+friends.#[age>45]#.last ["Craig","Murphy"]
+friends.#[first%"D*"].last "Murphy"
+friends.#[first!%"D*"].last "Craig"
+```
+
+To query for a non-object value in an array, you can forgo the string to the right of the operator.
+```go
+children.#[!%"*a*"] "Alex"
+children.#[%"*a*"]# ["Sara","Jack"]
+```
+
+
+
+### Dot vs Pipe
+
+The `.` is standard separator, but it's also possible to use a `|`.
+In most cases they both end up returning the same results.
+The cases where`|` differs from `.` is when it's used after the `#` for [Arrays](#arrays) and [Queries](#queries).
+
+Here are some examples
+
+```go
+friends.0.first "Dale"
+friends|0.first "Dale"
+friends.0|first "Dale"
+friends|0|first "Dale"
+friends|# 3
+friends.# 3
+friends.#[last="Murphy"]# [{"first": "Dale", "last": "Murphy", "age": 44},{"first": "Jane", "last": "Murphy", "age": 47}]
+friends.#[last="Murphy"]#.first ["Dale","Jane"]
+friends.#[last="Murphy"]#|first
+friends.#[last="Murphy"]#.0 []
+friends.#[last="Murphy"]#|0 {"first": "Dale", "last": "Murphy", "age": 44}
+friends.#[last="Murphy"]#.# []
+friends.#[last="Murphy"]#|# 2
+```
+
+Let's break down a few of these.
+
+The path `friends.#[last="Murphy"]#` all by itself results in
+
+```json
+[{"first": "Dale", "last": "Murphy", "age": 44},{"first": "Jane", "last": "Murphy", "age": 47}]
+```
+
+The `.first` suffix will process the `first` path on each array element *before* returning the results. Which becomes
+
+```json
+["Dale","Jane"]
+```
+
+But the `|first` suffix actually processes the `first` path *after* the previous result.
+Since the previous result is an array, not an object, it's not possible to process
+because `first` does not exist.
+
+Yet, `|0` suffix returns
+
+```json
+{"first": "Dale", "last": "Murphy", "age": 44}
+```
+
+Because `0` is the first index of the previous result.
+
+### Modifiers
+
+A modifier is a path component that performs custom processing on the JSON.
+
+For example, using the built-in `@reverse` modifier on the above JSON payload will reverse the `children` array:
+
+```go
+children.@reverse ["Jack","Alex","Sara"]
+children.@reverse.0 "Jack"
+```
+
+There are currently three built-in modifiers:
+
+- `@reverse`: Reverse an array or the members of an object.
+- `@ugly`: Remove all whitespace from JSON.
+- `@pretty`: Make the JSON more human readable.
+
+#### Modifier arguments
+
+A modifier may accept an optional argument. The argument can be a valid JSON payload or just characters.
+
+For example, the `@pretty` modifier takes a json object as its argument.
+
+```
+@pretty:{"sortKeys":true}
+```
+
+Which makes the json pretty and orders all of its keys.
+
+```json
+{
+ "age":37,
+ "children": ["Sara","Alex","Jack"],
+ "fav.movie": "Deer Hunter",
+ "friends": [
+ {"age": 44, "first": "Dale", "last": "Murphy"},
+ {"age": 68, "first": "Roger", "last": "Craig"},
+ {"age": 47, "first": "Jane", "last": "Murphy"}
+ ],
+ "name": {"first": "Tom", "last": "Anderson"}
+}
+```
+
+*The full list of `@pretty` options are `sortKeys`, `indent`, `prefix`, and `width`.
+Please see [Pretty Options](https://github.com/tidwall/pretty#customized-output) for more information.*
+
+#### Custom modifiers
+
+You can also add custom modifiers.
+
+For example, here we create a modifier which makes the entire JSON payload upper or lower case.
+
+```go
+gjson.AddModifier("case", func(json, arg string) string {
+ if arg == "upper" {
+ return strings.ToUpper(json)
+ }
+ if arg == "lower" {
+ return strings.ToLower(json)
+ }
+ return json
+})
+"children.@case:upper" ["SARA","ALEX","JACK"]
+"children.@case:lower.@reverse" ["jack","alex","sara"]
+```

+# Pretty
+[](https://travis-ci.org/tidwall/prettty)
+[](http://gocover.io/github.com/tidwall/pretty)
+[](https://godoc.org/github.com/tidwall/pretty)
+
+
+Pretty is a Go package that provides [fast](#performance) methods for formatting JSON for human readability, or to compact JSON for smaller payloads.
+
+Getting Started
+===============
+
+## Installing
+
+To start using Pretty, install Go and run `go get`:
+
+```sh
+$ go get -u github.com/tidwall/pretty
+```
+
+This will retrieve the library.
+
+## Pretty
+
+Using this example:
+
+```json
+{"name": {"first":"Tom","last":"Anderson"}, "age":37,
+"children": ["Sara","Alex","Jack"],
+"fav.movie": "Deer Hunter", "friends": [
+ {"first": "Janet", "last": "Murphy", "age": 44}
+ ]}
+```
+
+The following code:
+```go
+result = pretty.Pretty(example)
+```
+
+Will format the json to:
+
+```json
+{
+ "name": {
+ "first": "Tom",
+ "last": "Anderson"
+ },
+ "age": 37,
+ "children": ["Sara", "Alex", "Jack"],
+ "fav.movie": "Deer Hunter",
+ "friends": [
+ {
+ "first": "Janet",
+ "last": "Murphy",
+ "age": 44
+ }
+ ]
+}
+```
+
+## Color
+
+Color will colorize the json for outputing to the screen.
+
+```json
+result = pretty.Color(json, nil)
+```
+
+Will add color to the result for printing to the terminal.
+The second param is used for a customizing the style, and passing nil will use the default `pretty.TerminalStyle`.
+
+## Ugly
+
+The following code:
+```go
+result = pretty.Ugly(example)
+```
+
+Will format the json to:
+
+```json
+{"name":{"first":"Tom","last":"Anderson"},"age":37,"children":["Sara","Alex","Jack"],"fav.movie":"Deer Hunter","friends":[{"first":"Janet","last":"Murphy","age":44}]}```
+```
+
+
+## Customized output
+
+There's a `PrettyOptions(json, opts)` function which allows for customizing the output with the following options:
+
+```go
+type Options struct {
+ // Width is an max column width for single line arrays
+ // Default is 80
+ Width int
+ // Prefix is a prefix for all lines
+ // Default is an empty string
+ Prefix string
+ // Indent is the nested indentation
+ // Default is two spaces
+ Indent string
+ // SortKeys will sort the keys alphabetically
+ // Default is false
+ SortKeys bool
+}
+```
+## Performance
+
+Benchmarks of Pretty alongside the builtin `encoding/json` Indent/Compact methods.
+```
+BenchmarkPretty-8 1000000 1283 ns/op 720 B/op 2 allocs/op
+BenchmarkUgly-8 3000000 426 ns/op 240 B/op 1 allocs/op
+BenchmarkUglyInPlace-8 5000000 340 ns/op 0 B/op 0 allocs/op
+BenchmarkJSONIndent-8 300000 4628 ns/op 1069 B/op 4 allocs/op
+BenchmarkJSONCompact-8 1000000 2469 ns/op 758 B/op 4 allocs/op
+```
+
+*These benchmarks were run on a MacBook Pro 15" 2.8 GHz Intel Core i7 using Go 1.7.*

+# 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
+`go get -u go.uber.org/atomic`
+
+## 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.Combine(reader.Close(), writer.Close())
+//
+// This makes it possible to record resource cleanup failures from deferred
+// blocks with the help of named return values.
+//
+// func sendRequest(req Request) (err error) {
+// conn, err := openConnection()
+// if err != nil {
+// return err
+// }
+// defer func() {
+// err = multierr.Append(err, conn.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:")
+// }
+//
+// 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}

+
+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 — 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 — it's also faster than the
+standard library. Like all benchmarks, take these with a grain of salt.[1](#footnote-versions)
+
+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 —
+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
+issues and pull requests, but you can also report any negative conduct to
+oss-conduct@uber.com. That email list is a private, safe space; even the zap
+maintainers don't have access, so don't hesitate to hold us to a high
+standard.
+
+
+
+Released under the [MIT License](LICENSE.txt).
+
+ In particular, keep in mind that we may be
+benchmarking against slightly older versions of other packages. Versions are
+pinned in zap's [glide.lock][] file. [↩](#anchor-versions)

+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"** — 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.

+# Contributing
+
+We'd love your help making zap the very best structured logging library in Go!
+
+If you'd like to add new exported APIs, please [open an issue][open-issue]
+describing your proposal — discussing API changes ahead of time makes
+pull request review much smoother. In your issue, pull request, and any other
+communications, please remember to treat your fellow contributors with
+respect! We take our [code of conduct](CODE_OF_CONDUCT.md) seriously.
+
+Note that you'll need to sign [Uber's Contributor License Agreement][cla]
+before we can accept any of your contributions. If necessary, a bot will remind
+you to accept the CLA when you open your pull request.
+
+## Setup
+
+[Fork][fork], then clone the repository:
+
+```
+mkdir -p $GOPATH/src/go.uber.org
+cd $GOPATH/src/go.uber.org
+git clone git@github.com:your_github_username/zap.git
+cd zap
+git remote add upstream https://github.com/uber-go/zap.git
+git fetch upstream
+```
+
+Install zap's dependencies:
+
+```
+make dependencies
+```
+
+Make sure that the tests and the linters pass:
+
+```
+make test
+make lint
+```
+
+If you're not using the minor version of Go specified in the Makefile's
+`LINTABLE_MINOR_VERSIONS` variable, `make lint` doesn't do anything. This is
+fine, but it means that you'll only discover lint failures after you open your
+pull request.
+
+## Making Changes
+
+Start by creating a new branch for your changes:
+
+```
+cd $GOPATH/src/go.uber.org/zap
+git checkout master
+git fetch upstream
+git rebase upstream/master
+git checkout -b cool_new_feature
+```
+
+Make your changes, then ensure that `make lint` and `make test` still pass. If
+you're satisfied with your changes, push them to your fork.
+
+```
+git push origin cool_new_feature
+```
+
+Then use the GitHub UI to open a pull request.
+
+At this point, you're waiting on us to review your changes. We *try* to respond
+to issues and pull requests within a few business days, and we may suggest some
+improvements or alternatives. Once your changes are approved, one of the
+project maintainers will merge them.
+
+We're much more likely to approve your changes if you:
+
+* Add tests for new functionality.
+* Write a [good commit message][commit-message].
+* Maintain backward compatibility.

+# 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 — *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 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
+— especially the reason for the crash — 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 |

+# :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 — 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 — it's also faster than the
+standard library. Like all benchmarks, take these with a grain of salt.[1](#footnote-versions)
+
+Log a message and 10 fields:
+
+| Package | Time | Objects Allocated |
+| :--- | :---: | :---: |
+| :zap: zap | 3131 ns/op | 5 allocs/op |
+| :zap: zap (sugared) | 4173 ns/op | 21 allocs/op |
+| zerolog | 16154 ns/op | 90 allocs/op |
+| lion | 16341 ns/op | 111 allocs/op |
+| go-kit | 17049 ns/op | 126 allocs/op |
+| logrus | 23662 ns/op | 142 allocs/op |
+| log15 | 36351 ns/op | 149 allocs/op |
+| apex/log | 42530 ns/op | 126 allocs/op |
+
+Log a message with a logger that already has 10 fields of context:
+
+| Package | Time | Objects Allocated |
+| :--- | :---: | :---: |
+| :zap: zap | 380 ns/op | 0 allocs/op |
+| :zap: zap (sugared) | 564 ns/op | 2 allocs/op |
+| zerolog | 321 ns/op | 0 allocs/op |
+| lion | 7092 ns/op | 39 allocs/op |
+| go-kit | 20226 ns/op | 115 allocs/op |
+| logrus | 22312 ns/op | 130 allocs/op |
+| log15 | 28788 ns/op | 79 allocs/op |
+| apex/log | 42063 ns/op | 115 allocs/op |
+
+Log a static string, without any context or `printf`-style templating:
+
+| Package | Time | Objects Allocated |
+| :--- | :---: | :---: |
+| :zap: zap | 361 ns/op | 0 allocs/op |
+| :zap: zap (sugared) | 534 ns/op | 2 allocs/op |
+| zerolog | 323 ns/op | 0 allocs/op |
+| standard library | 575 ns/op | 2 allocs/op |
+| go-kit | 922 ns/op | 13 allocs/op |
+| lion | 1413 ns/op | 10 allocs/op |
+| logrus | 2291 ns/op | 27 allocs/op |
+| apex/log | 3690 ns/op | 11 allocs/op |
+| log15 | 5954 ns/op | 26 allocs/op |
+
+## 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 —
+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
+issues and pull requests, but you can also report any negative conduct to
+oss-conduct@uber.com. That email list is a private, safe space; even the zap
+maintainers don't have access, so don't hesitate to hold us to a high
+standard.

+
+// 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.

+Package pbkdf2 implements the key derivation function PBKDF2 as defined in RFC
+2898 / PKCS #5 v2.0.
+
+A key derivation function is useful when encrypting data based on a password
+or any other not-fully-random data. It uses a pseudorandom function to derive
+a secure encryption key based on the password.
+
+While v2.0 of the standard defines only one pseudorandom function to use,
+HMAC-SHA1, the drafted v2.1 specification allows use of all five FIPS Approved
+Hash Functions SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 for HMAC. To
+choose, you can pass the `New` functions from the different SHA packages to
+pbkdf2.Key.

+// Key derives a key from the password, salt and iteration count, returning a
+// []byte of length keylen that can be used as cryptographic key. The key is
+// derived based on the method described as PBKDF2 with the HMAC variant using
+// the supplied hash function.
+//
+// For example, to use a HMAC-SHA-1 based PBKDF2 key derivation function, you
+// can get a derived key for e.g. AES-256 (which needs a 32-byte key) by
+// doing:
+//
+// dk := pbkdf2.Key([]byte("some password"), salt, 4096, 32, sha1.New)
+//
+// Remember to get a good random salt. At least 8 bytes is recommended by the
+// RFC.
+//
+// Using a higher iteration count will increase the cost of an exhaustive
+// search but will also make derivation proportionally slower.

+# Building `sys/unix`
+
+The sys/unix package provides access to the raw system call interface of the
+underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
+
+Porting Go to a new architecture/OS combination or adding syscalls, types, or
+constants to an existing architecture/OS pair requires some manual effort;
+however, there are tools that automate much of the process.
+
+## Build Systems
+
+There are currently two ways we generate the necessary files. We are currently
+migrating the build system to use containers so the builds are reproducible.
+This is being done on an OS-by-OS basis. Please update this documentation as
+components of the build system change.
+
+### Old Build System (currently for `GOOS != "linux"`)
+
+The old build system generates the Go files based on the C header files
+present on your system. This means that files
+for a given GOOS/GOARCH pair must be generated on a system with that OS and
+architecture. This also means that the generated code can differ from system
+to system, based on differences in the header files.
+
+To avoid this, if you are using the old build system, only generate the Go
+files on an installation with unmodified header files. It is also important to
+keep track of which version of the OS the files were generated from (ex.
+Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
+and have each OS upgrade correspond to a single change.
+
+To build the files for your current OS and architecture, make sure GOOS and
+GOARCH are set correctly and run `mkall.sh`. This will generate the files for
+your specific system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, go
+
+### New Build System (currently for `GOOS == "linux"`)
+
+The new build system uses a Docker container to generate the go files directly
+from source checkouts of the kernel and various system libraries. This means
+that on any platform that supports Docker, all the files using the new build
+system can be generated at once, and generated files will not change based on
+what the person running the scripts has installed on their computer.
+
+The OS specific files for the new build system are located in the `${GOOS}`
+directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
+the kernel or system library updates, modify the Dockerfile at
+`${GOOS}/Dockerfile` to checkout the new release of the source.
+
+To build all the files under the new build system, you must be on an amd64/Linux
+system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
+then generate all of the files for all of the GOOS/GOARCH pairs in the new build
+system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, go, docker
+
+## Component files
+
+This section describes the various files used in the code generation process.
+It also contains instructions on how to modify these files to add a new
+architecture/OS or to add additional syscalls, types, or constants. Note that
+if you are using the new build system, the scripts/programs cannot be called normally.
+They must be called from within the docker container.
+
+### asm files
+
+The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
+call dispatch. There are three entry points:
+```
+ func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+ func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+ func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+```
+The first and second are the standard ones; they differ only in how many
+arguments can be passed to the kernel. The third is for low-level use by the
+ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
+let it know that a system call is running.
+
+When porting Go to an new architecture/OS, this file must be implemented for
+each GOOS/GOARCH pair.
+
+### mksysnum
+
+Mksysnum is a Go program located at `${GOOS}/mksysnum.go` (or `mksysnum_${GOOS}.go`
+for the old system). This program takes in a list of header files containing the
+syscall number declarations and parses them to produce the corresponding list of
+Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
+constants.
+
+Adding new syscall numbers is mostly done by running the build on a sufficiently
+new installation of the target OS (or updating the source checkouts for the
+new build system). However, depending on the OS, you make need to update the
+parsing in mksysnum.
+
+### mksyscall.go
+
+The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
+hand-written Go files which implement system calls (for unix, the specific OS,
+or the specific OS/Architecture pair respectively) that need special handling
+and list `//sys` comments giving prototypes for ones that can be generated.
+
+The mksyscall.go program takes the `//sys` and `//sysnb` comments and converts
+them into syscalls. This requires the name of the prototype in the comment to
+match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
+prototype can be exported (capitalized) or not.
+
+Adding a new syscall often just requires adding a new `//sys` function prototype
+with the desired arguments and a capitalized name so it is exported. However, if
+you want the interface to the syscall to be different, often one will make an
+unexported `//sys` prototype, an then write a custom wrapper in
+`syscall_${GOOS}.go`.
+
+### types files
+
+For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
+`types_${GOOS}.go` on the old system). This file includes standard C headers and
+creates Go type aliases to the corresponding C types. The file is then fed
+through godef to get the Go compatible definitions. Finally, the generated code
+is fed though mkpost.go to format the code correctly and remove any hidden or
+private identifiers. This cleaned-up code is written to
+`ztypes_${GOOS}_${GOARCH}.go`.
+
+The hardest part about preparing this file is figuring out which headers to
+include and which symbols need to be `#define`d to get the actual data
+structures that pass through to the kernel system calls. Some C libraries
+preset alternate versions for binary compatibility and translate them on the
+way in and out of system calls, but there is almost always a `#define` that can
+get the real ones.
+See `types_darwin.go` and `linux/types.go` for examples.
+
+To add a new type, add in the necessary include statement at the top of the
+file (if it is not already there) and add in a type alias line. Note that if
+your type is significantly different on different architectures, you may need
+some `#if/#elif` macros in your include statements.
+
+### mkerrors.sh
+
+This script is used to generate the system's various constants. This doesn't
+just include the error numbers and error strings, but also the signal numbers
+an a wide variety of miscellaneous constants. The constants come from the list
+of include files in the `includes_${uname}` variable. A regex then picks out
+the desired `#define` statements, and generates the corresponding Go constants.
+The error numbers and strings are generated from `#include `, and the
+signal numbers and strings are generated from `#include `. All of
+these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
+`_errors.c`, which prints out all the constants.
+
+To add a constant, add the header that includes it to the appropriate variable.
+Then, edit the regex (if necessary) to match the desired constant. Avoid making
+the regex too broad to avoid matching unintended constants.
+
+
+## Generated files
+
+### `zerror_${GOOS}_${GOARCH}.go`
+
+A file containing all of the system's generated error numbers, error strings,
+signal numbers, and constants. Generated by `mkerrors.sh` (see above).
+
+### `zsyscall_${GOOS}_${GOARCH}.go`
+
+A file containing all the generated syscalls for a specific GOOS and GOARCH.
+Generated by `mksyscall.go` (see above).
+
+### `zsysnum_${GOOS}_${GOARCH}.go`
+
+A list of numeric constants for all the syscall number of the specific GOOS
+and GOARCH. Generated by mksysnum (see above).
+
+### `ztypes_${GOOS}_${GOARCH}.go`
+
+A file containing Go types for passing into (or returning from) syscalls.
+Generated by godefs and the types file (see above).

+This program reads a file containing function prototypes
+(like syscall_aix.go) and generates system call bodies.
+The prototypes are marked by lines beginning with "//sys"
+and read like func declarations if //sys is replaced by func, but:
+ * The parameter lists must give a name for each argument.
+ This includes return parameters.
+ * The parameter lists must give a type for each argument:
+ the (x, y, z int) shorthand is not allowed.
+ * If the return parameter is an error number, it must be named err.
+ * If go func name needs to be different than its libc name,
+ * or the function is not in libc, name could be specified
+ * at the end, after "=" sign, like
+ //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
+
+
+This program will generate three files and handle both gc and gccgo implementation:
+ - zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
+ - zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
+ - zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
+
+ The generated code looks like this
+
+zsyscall_aix_ppc64.go
+func asyscall(...) (n int, err error) {
+ // Pointer Creation
+ r1, e1 := callasyscall(...)
+ // Type Conversion
+ // Error Handler

+// SockaddrALG enables userspace access to the Linux kernel's cryptography

+// should be used with a given socket.
+//
+// To create a file descriptor that provides access to a hash or cipher, both
+// Bind and Accept must be used. Once the setup process is complete, input
+// data can be written to the socket, processed by the kernel, and then read
+// back as hash output or ciphertext.
+//
+// Here is an example of using an AF_ALG socket with SHA1 hashing.
+// The initial socket setup process is as follows:
+//
+// // Open a socket to perform SHA1 hashing.
+// fd, _ := unix.Socket(unix.AF_ALG, unix.SOCK_SEQPACKET, 0)
+// addr := &unix.SockaddrALG{Type: "hash", Name: "sha1"}
+// unix.Bind(fd, addr)
+// // Note: unix.Accept does not work at this time; must invoke accept()
+// // manually using unix.Syscall.
+// hashfd, _, _ := unix.Syscall(unix.SYS_ACCEPT, uintptr(fd), 0, 0)
+//
+// Once a file descriptor has been returned from Accept, it may be used to
+// perform SHA1 hashing. The descriptor is not safe for concurrent use, but
+// may be re-used repeatedly with subsequent Write and Read operations.
+//
+// When hashing a small byte slice or string, a single Write and Read may
+// be used:
+//
+// // Assume hashfd is already configured using the setup process.
+// hash := os.NewFile(hashfd, "sha1")
+// // Hash an input string and read the results. Each Write discards
+// // previous hash state. Read always reads the current state.
+// b := make([]byte, 20)
+// for i := 0; i < 2; i++ {
+// io.WriteString(hash, "Hello, world.")
+// hash.Read(b)
+// fmt.Println(hex.EncodeToString(b))
+// }
+// // Output:
+// // 2ae01472317d1935a84797ec1983ae243fc6aa28
+// // 2ae01472317d1935a84797ec1983ae243fc6aa28
+//
+// For hashing larger byte slices, or byte streams such as those read from
+// a file or socket, use Sendto with MSG_MORE to instruct the kernel to update
+// the hash digest instead of creating a new one for a given chunk and finalizing it.
+//
+// // Assume hashfd and addr are already configured using the setup process.
+// hash := os.NewFile(hashfd, "sha1")
+// // Hash the contents of a file.
+// f, _ := os.Open("/tmp/linux-4.10-rc7.tar.xz")
