-## Getting Started
-
-```bash
-GO111MODULE=on go get -u github.com/asdine/storm/v3
-```
-
-## Import Storm
-
-```go
-import "github.com/asdine/storm/v3"
-```
-
-## Open a database
-
-Quick way of opening a database
-
-```go
-db, err := storm.Open("my.db")
-
-defer db.Close()
-```
-
-`Open` can receive multiple options to customize the way it behaves. See [Options](#options) below
-
-## Simple CRUD system
-
-### Declare your structures
-
-```go
-type User struct {
- ID int // primary key
- Group string `storm:"index"` // this field will be indexed
- Email string `storm:"unique"` // this field will be indexed with a unique constraint
- Name string // this field will not be indexed
- Age int `storm:"index"`
-}
-```
-
-The primary key can be of any type as long as it is not a zero value. Storm will search for the tag `id`, if not present Storm will search for a field named `ID`.
-
-```go
-type User struct {
- ThePrimaryKey string `storm:"id"`// primary key
- Group string `storm:"index"` // this field will be indexed
- Email string `storm:"unique"` // this field will be indexed with a unique constraint
- Name string // this field will not be indexed
-}
-```
-
-Storm handles tags in nested structures with the `inline` tag
-
-```go
-type Base struct {
- Ident bson.ObjectId `storm:"id"`
-}
-
-type User struct {
- Base `storm:"inline"`
- Group string `storm:"index"`
- Email string `storm:"unique"`
- Name string
- CreatedAt time.Time `storm:"index"`
-}
-```
-
-### Save your object
-
-```go
-user := User{
- ID: 10,
- Group: "staff",
- Email: "john@provider.com",
- Name: "John",
- Age: 21,
- CreatedAt: time.Now(),
-}
-
-err := db.Save(&user)
-// err == nil
-
-user.ID++
-err = db.Save(&user)
-// err == storm.ErrAlreadyExists
-```
-
-That's it.
-
-`Save` creates or updates all the required indexes and buckets, checks the unique constraints and saves the object to the store.
-
-#### Auto Increment
-
-Storm can auto increment integer values so you don't have to worry about that when saving your objects. Also, the new value is automatically inserted in your field.
-
-```go
-
-type Product struct {
- Pk int `storm:"id,increment"` // primary key with auto increment
- Name string
- IntegerField uint64 `storm:"increment"`
- IndexedIntegerField uint32 `storm:"index,increment"`
- UniqueIntegerField int16 `storm:"unique,increment=100"` // the starting value can be set
-}
-
-p := Product{Name: "Vaccum Cleaner"}
-
-fmt.Println(p.Pk)
-fmt.Println(p.IntegerField)
-fmt.Println(p.IndexedIntegerField)
-fmt.Println(p.UniqueIntegerField)
-// 0
-// 0
-// 0
-// 0
-
-_ = db.Save(&p)
-
-fmt.Println(p.Pk)
-fmt.Println(p.IntegerField)
-fmt.Println(p.IndexedIntegerField)
-fmt.Println(p.UniqueIntegerField)
-// 1
-// 1
-// 1
-// 100
-
-```
-
-### Simple queries
-
-Any object can be fetched, indexed or not. Storm uses indexes when available, otherwise it uses the [query system](#advanced-queries).
-
-#### Fetch one object
-
-```go
-var user User
-err := db.One("Email", "john@provider.com", &user)
-// err == nil
-
-err = db.One("Name", "John", &user)
-// err == nil
-
-err = db.One("Name", "Jack", &user)
-// err == storm.ErrNotFound
-```
-
-#### Fetch multiple objects
-
-```go
-var users []User
-err := db.Find("Group", "staff", &users)
-```
-
-#### Fetch all objects
-
-```go
-var users []User
-err := db.All(&users)
-```
-
-#### Fetch all objects sorted by index
-
-```go
-var users []User
-err := db.AllByIndex("CreatedAt", &users)
-```
-
-#### Fetch a range of objects
-
-```go
-var users []User
-err := db.Range("Age", 10, 21, &users)
-```
-
-#### Fetch objects by prefix
-
-```go
-var users []User
-err := db.Prefix("Name", "Jo", &users)
-```
-
-#### Skip, Limit and Reverse
-
-```go
-var users []User
-err := db.Find("Group", "staff", &users, storm.Skip(10))
-err = db.Find("Group", "staff", &users, storm.Limit(10))
-err = db.Find("Group", "staff", &users, storm.Reverse())
-err = db.Find("Group", "staff", &users, storm.Limit(10), storm.Skip(10), storm.Reverse())
-
-err = db.All(&users, storm.Limit(10), storm.Skip(10), storm.Reverse())
-err = db.AllByIndex("CreatedAt", &users, storm.Limit(10), storm.Skip(10), storm.Reverse())
-err = db.Range("Age", 10, 21, &users, storm.Limit(10), storm.Skip(10), storm.Reverse())
-```
-
-#### Delete an object
-
-```go
-err := db.DeleteStruct(&user)
-```
-
-#### Update an object
-
-```go
-// Update multiple fields
-err := db.Update(&User{ID: 10, Name: "Jack", Age: 45})
-
-// Update a single field
-err := db.UpdateField(&User{ID: 10}, "Age", 0)
-```
-
-#### Initialize buckets and indexes before saving an object
-
-```go
-err := db.Init(&User{})
-```
-
-Useful when starting your application
-
-#### Drop a bucket
-
-Using the struct
-
-```go
-err := db.Drop(&User)
-```
-
-Using the bucket name
-
-```go
-err := db.Drop("User")
-```
-
-#### Re-index a bucket
-
-```go
-err := db.ReIndex(&User{})
-```
-
-Useful when the structure has changed
-
-### Advanced queries
-
-For more complex queries, you can use the `Select` method.
-`Select` takes any number of [`Matcher`](https://godoc.org/github.com/asdine/storm/q#Matcher) from the [`q`](https://godoc.org/github.com/asdine/storm/q) package.
-
-Here are some common Matchers:
-
-```go
-// Equality
-q.Eq("Name", John)
-
-// Strictly greater than
-q.Gt("Age", 7)
-
-// Lesser than or equal to
-q.Lte("Age", 77)
-
-// Regex with name that starts with the letter D
-q.Re("Name", "^D")
-
-// In the given slice of values
-q.In("Group", []string{"Staff", "Admin"})
-
-// Comparing fields
-q.EqF("FieldName", "SecondFieldName")
-q.LtF("FieldName", "SecondFieldName")
-q.GtF("FieldName", "SecondFieldName")
-q.LteF("FieldName", "SecondFieldName")
-q.GteF("FieldName", "SecondFieldName")
-```
-
-Matchers can also be combined with `And`, `Or` and `Not`:
-
-```go
-
-// Match if all match
-q.And(
- q.Gt("Age", 7),
- q.Re("Name", "^D")
-)
-
-// Match if one matches
-q.Or(
- q.Re("Name", "^A"),
- q.Not(
- q.Re("Name", "^B")
- ),
- q.Re("Name", "^C"),
- q.In("Group", []string{"Staff", "Admin"}),
- q.And(
- q.StrictEq("Password", []byte(password)),
- q.Eq("Registered", true)
- )
-)
-```
-
-You can find the complete list in the [documentation](https://godoc.org/github.com/asdine/storm/q#Matcher).
-
-`Select` takes any number of matchers and wraps them into a `q.And()` so it's not necessary to specify it. It returns a [`Query`](https://godoc.org/github.com/asdine/storm#Query) type.
-
-```go
-query := db.Select(q.Gte("Age", 7), q.Lte("Age", 77))
-```
-
-The `Query` type contains methods to filter and order the records.
-
-```go
-// Limit
-query = query.Limit(10)
-
-// Skip
-query = query.Skip(20)
-
-// Calls can also be chained
-query = query.Limit(10).Skip(20).OrderBy("Age").Reverse()
-```
-
-But also to specify how to fetch them.
-
-```go
-var users []User
-err = query.Find(&users)
-
-var user User
-err = query.First(&user)
-```
-
-Examples with `Select`:
-
-```go
-// Find all users with an ID between 10 and 100
-err = db.Select(q.Gte("ID", 10), q.Lte("ID", 100)).Find(&users)
-
-// Nested matchers
-err = db.Select(q.Or(
- q.Gt("ID", 50),
- q.Lt("Age", 21),
- q.And(
- q.Eq("Group", "admin"),
- q.Gte("Age", 21),
- ),
-)).Find(&users)
-
-query := db.Select(q.Gte("ID", 10), q.Lte("ID", 100)).Limit(10).Skip(5).Reverse().OrderBy("Age", "Name")
-
-// Find multiple records
-err = query.Find(&users)
-// or
-err = db.Select(q.Gte("ID", 10), q.Lte("ID", 100)).Limit(10).Skip(5).Reverse().OrderBy("Age", "Name").Find(&users)
-
-// Find first record
-err = query.First(&user)
-// or
-err = db.Select(q.Gte("ID", 10), q.Lte("ID", 100)).Limit(10).Skip(5).Reverse().OrderBy("Age", "Name").First(&user)
-
-// Delete all matching records
-err = query.Delete(new(User))
-
-// Fetching records one by one (useful when the bucket contains a lot of records)
-query = db.Select(q.Gte("ID", 10),q.Lte("ID", 100)).OrderBy("Age", "Name")
-
-err = query.Each(new(User), func(record interface{}) error) {
- u := record.(*User)
- ...
- return nil
-}
-```
-
-See the [documentation](https://godoc.org/github.com/asdine/storm#Query) for a complete list of methods.
-
-### Transactions
-
-```go
-tx, err := db.Begin(true)
-if err != nil {
- return err
-}
-defer tx.Rollback()
-
-accountA.Amount -= 100
-accountB.Amount += 100
-
-err = tx.Save(accountA)
-if err != nil {
- return err
-}
-
-err = tx.Save(accountB)
-if err != nil {
- return err
-}
-
-return tx.Commit()
-```
-
-### Options
-
-Storm options are functions that can be passed when constructing you Storm instance. You can pass it any number of options.
-
-#### BoltOptions
-
-By default, Storm opens a database with the mode `0600` and a timeout of one second.
-You can change this behavior by using `BoltOptions`
-
-```go
-db, err := storm.Open("my.db", storm.BoltOptions(0600, &bolt.Options{Timeout: 1 * time.Second}))
-```
-
-#### MarshalUnmarshaler
-
-To store the data in BoltDB, Storm marshals it in JSON by default. If you wish to change this behavior you can pass a codec that implements [`codec.MarshalUnmarshaler`](https://godoc.org/github.com/asdine/storm/codec#MarshalUnmarshaler) via the [`storm.Codec`](https://godoc.org/github.com/asdine/storm#Codec) option:
-
-```go
-db := storm.Open("my.db", storm.Codec(myCodec))
-```
-
-##### Provided Codecs
-
-You can easily implement your own `MarshalUnmarshaler`, but Storm comes with built-in support for [JSON](https://godoc.org/github.com/asdine/storm/codec/json) (default), [GOB](https://godoc.org/github.com/asdine/storm/codec/gob), [Sereal](https://godoc.org/github.com/asdine/storm/codec/sereal), [Protocol Buffers](https://godoc.org/github.com/asdine/storm/codec/protobuf) and [MessagePack](https://godoc.org/github.com/asdine/storm/codec/msgpack).
-
-These can be used by importing the relevant package and use that codec to configure Storm. The example below shows all variants (without proper error handling):
-
-```go
-import (
- "github.com/asdine/storm/v3"
- "github.com/asdine/storm/v3/codec/gob"
- "github.com/asdine/storm/v3/codec/json"
- "github.com/asdine/storm/v3/codec/sereal"
- "github.com/asdine/storm/v3/codec/protobuf"
- "github.com/asdine/storm/v3/codec/msgpack"
-)
-
-var gobDb, _ = storm.Open("gob.db", storm.Codec(gob.Codec))
-var jsonDb, _ = storm.Open("json.db", storm.Codec(json.Codec))
-var serealDb, _ = storm.Open("sereal.db", storm.Codec(sereal.Codec))
-var protobufDb, _ = storm.Open("protobuf.db", storm.Codec(protobuf.Codec))
-var msgpackDb, _ = storm.Open("msgpack.db", storm.Codec(msgpack.Codec))
-```
-
-**Tip**: Adding Storm tags to generated Protobuf files can be tricky. A good solution is to use [this tool](https://github.com/favadi/protoc-go-inject-tag) to inject the tags during the compilation.
-
-#### Use existing Bolt connection
-
-You can use an existing connection and pass it to Storm
-
-```go
-bDB, _ := bolt.Open(filepath.Join(dir, "bolt.db"), 0600, &bolt.Options{Timeout: 10 * time.Second})
-db := storm.Open("my.db", storm.UseDB(bDB))
-```
-
-#### Batch mode
-
-Batch mode can be enabled to speed up concurrent writes (see [Batch read-write transactions](https://github.com/coreos/bbolt#batch-read-write-transactions))
-
-```go
-db := storm.Open("my.db", storm.Batch())
-```
-
-## Nodes and nested buckets
-
-Storm takes advantage of BoltDB nested buckets feature by using `storm.Node`.
-A `storm.Node` is the underlying object used by `storm.DB` to manipulate a bucket.
-To create a nested bucket and use the same API as `storm.DB`, you can use the `DB.From` method.
-
-```go
-repo := db.From("repo")
-
-err := repo.Save(&Issue{
- Title: "I want more features",
- Author: user.ID,
-})
-
-err = repo.Save(newRelease("0.10"))
-
-var issues []Issue
-err = repo.Find("Author", user.ID, &issues)
-
-var release Release
-err = repo.One("Tag", "0.10", &release)
-```
-
-You can also chain the nodes to create a hierarchy
-
-```go
-chars := db.From("characters")
-heroes := chars.From("heroes")
-enemies := chars.From("enemies")
-
-items := db.From("items")
-potions := items.From("consumables").From("medicine").From("potions")
-```
-
-You can even pass the entire hierarchy as arguments to `From`:
-
-```go
-privateNotes := db.From("notes", "private")
-workNotes := db.From("notes", "work")
-```
-
-### Node options
-
-A Node can also be configured. Activating an option on a Node creates a copy, so a Node is always thread-safe.
-
-```go
-n := db.From("my-node")
-```
-
-Give a bolt.Tx transaction to the Node
-
-```go
-n = n.WithTransaction(tx)
-```
-
-Enable batch mode
-
-```go
-n = n.WithBatch(true)
-```
-
-Use a Codec
-
-```go
-n = n.WithCodec(gob.Codec)
-```
-
-## Simple Key/Value store
-
-Storm can be used as a simple, robust, key/value store that can store anything.
-The key and the value can be of any type as long as the key is not a zero value.
-
-Saving data :
-
-```go
-db.Set("logs", time.Now(), "I'm eating my breakfast man")
-db.Set("sessions", bson.NewObjectId(), &someUser)
-db.Set("weird storage", "754-3010", map[string]interface{}{
- "hair": "blonde",
- "likes": []string{"cheese", "star wars"},
-})
-```
-
-Fetching data :
-
-```go
-user := User{}
-db.Get("sessions", someObjectId, &user)
-
-var details map[string]interface{}
-db.Get("weird storage", "754-3010", &details)
-
-db.Get("sessions", someObjectId, &details)
-```
-
-Deleting data :
-
-```go
-db.Delete("sessions", someObjectId)
-db.Delete("weird storage", "754-3010")
-```
-
-You can find other useful methods in the [documentation](https://godoc.org/github.com/asdine/storm#KeyValueStore).
-
-## BoltDB
-
-BoltDB is still easily accessible and can be used as usual
-
-```go
-db.Bolt.View(func(tx *bolt.Tx) error {
- bucket := tx.Bucket([]byte("my bucket"))
- val := bucket.Get([]byte("any id"))
- fmt.Println(string(val))
- return nil
-})
-```
-
-A transaction can be also be passed to Storm
-
-```go
-db.Bolt.Update(func(tx *bolt.Tx) error {
- ...
- dbx := db.WithTransaction(tx)
- err = dbx.Save(&user)
- ...
- return nil
-})
-```

-# xxhash
-
-[](https://pkg.go.dev/github.com/cespare/xxhash/v2)
-[](https://github.com/cespare/xxhash/actions/workflows/test.yml)
-
-xxhash is a Go implementation of the 64-bit
-[xxHash](http://cyan4973.github.io/xxHash/) algorithm, XXH64. This is a
-high-quality hashing algorithm that is much faster than anything in the Go
-standard library.
-
-This package provides a straightforward API:
-
-```
-func Sum64(b []byte) uint64
-func Sum64String(s string) uint64
-type Digest struct{ ... }
- func New() *Digest
-```
-
-The `Digest` type implements hash.Hash64. Its key methods are:
-
-```
-func (*Digest) Write([]byte) (int, error)
-func (*Digest) WriteString(string) (int, error)
-func (*Digest) Sum64() uint64
-```
-
-This implementation provides a fast pure-Go implementation and an even faster
-assembly implementation for amd64.
-
-## Compatibility
-
-This package is in a module and the latest code is in version 2 of the module.
-You need a version of Go with at least "minimal module compatibility" to use
-github.com/cespare/xxhash/v2:
-
-* 1.9.7+ for Go 1.9
-* 1.10.3+ for Go 1.10
-* Go 1.11 or later
-
-I recommend using the latest release of Go.
-
-## Benchmarks
-
-Here are some quick benchmarks comparing the pure-Go and assembly
-implementations of Sum64.
-
-| input size | purego | asm |
-| --- | --- | --- |
-| 5 B | 979.66 MB/s | 1291.17 MB/s |
-| 100 B | 7475.26 MB/s | 7973.40 MB/s |
-| 4 KB | 17573.46 MB/s | 17602.65 MB/s |
-| 10 MB | 17131.46 MB/s | 17142.16 MB/s |
-
-These numbers were generated on Ubuntu 18.04 with an Intel i7-8700K CPU using
-the following commands under Go 1.11.2:
-
-```
-$ go test -tags purego -benchtime 10s -bench '/xxhash,direct,bytes'
-$ go test -benchtime 10s -bench '/xxhash,direct,bytes'
-```

-Package spew implements a deep pretty printer for Go data structures to aid in
-debugging.
-
-A quick overview of the additional features spew provides over the built-in
-printing facilities for Go data types are as follows:
-
- * Pointers are dereferenced and followed
- * Circular data structures are detected and handled properly
- * Custom Stringer/error interfaces are optionally invoked, including
- on unexported types
- * Custom types which only implement the Stringer/error interfaces via
- a pointer receiver are optionally invoked when passing non-pointer
- variables
- * Byte arrays and slices are dumped like the hexdump -C command which
- includes offsets, byte values in hex, and ASCII output (only when using
- Dump style)
-
-There are two different approaches spew allows for dumping Go data structures:
-
- * Dump style which prints with newlines, customizable indentation,
- and additional debug information such as types and all pointer addresses
- used to indirect to the final value
- * A custom Formatter interface that integrates cleanly with the standard fmt
- package and replaces %v, %+v, %#v, and %#+v to provide inline printing
- similar to the default %v while providing the additional functionality
- outlined above and passing unsupported format verbs such as %x and %q
- along to fmt
-
-Quick Start
-
-This section demonstrates how to quickly get started with spew. See the
-sections below for further details on formatting and configuration options.
-
-To dump a variable with full newlines, indentation, type, and pointer
-information use Dump, Fdump, or Sdump:
- spew.Dump(myVar1, myVar2, ...)
- spew.Fdump(someWriter, myVar1, myVar2, ...)
- str := spew.Sdump(myVar1, myVar2, ...)
-
-Alternatively, if you would prefer to use format strings with a compacted inline
-printing style, use the convenience wrappers Printf, Fprintf, etc with
-%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
-%#+v (adds types and pointer addresses):
- spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
- spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
- spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
- spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-Configuration Options
-
-Configuration of spew is handled by fields in the ConfigState type. For
-convenience, all of the top-level functions use a global state available
-via the spew.Config global.
-
-It is also possible to create a ConfigState instance that provides methods
-equivalent to the top-level functions. This allows concurrent configuration
-options. See the ConfigState documentation for more details.
-
-The following configuration options are available:
- * Indent
- String to use for each indentation level for Dump functions.
- It is a single space by default. A popular alternative is "\t".
-
- * MaxDepth
- Maximum number of levels to descend into nested data structures.
- There is no limit by default.
-
- * DisableMethods
- Disables invocation of error and Stringer interface methods.
- Method invocation is enabled by default.
-
- * DisablePointerMethods
- Disables invocation of error and Stringer interface methods on types
- which only accept pointer receivers from non-pointer variables.
- Pointer method invocation is enabled by default.
-
- * DisablePointerAddresses
- DisablePointerAddresses specifies whether to disable the printing of
- pointer addresses. This is useful when diffing data structures in tests.
-
- * DisableCapacities
- DisableCapacities specifies whether to disable the printing of
- capacities for arrays, slices, maps and channels. This is useful when
- diffing data structures in tests.
-
- * ContinueOnMethod
- Enables recursion into types after invoking error and Stringer interface
- methods. Recursion after method invocation is disabled by default.
-
- * SortKeys
- Specifies map keys should be sorted before being printed. Use
- this to have a more deterministic, diffable output. Note that
- only native types (bool, int, uint, floats, uintptr and string)
- and types which implement error or Stringer interfaces are
- supported with other types sorted according to the
- reflect.Value.String() output which guarantees display
- stability. Natural map order is used by default.
-
- * SpewKeys
- Specifies that, as a last resort attempt, map keys should be
- spewed to strings and sorted by those strings. This is only
- considered if SortKeys is true.
-
-Dump Usage
-
-Simply call spew.Dump with a list of variables you want to dump:
-
- spew.Dump(myVar1, myVar2, ...)
-
-You may also call spew.Fdump if you would prefer to output to an arbitrary
-io.Writer. For example, to dump to standard error:
-
- spew.Fdump(os.Stderr, myVar1, myVar2, ...)
-
-A third option is to call spew.Sdump to get the formatted output as a string:
-
- str := spew.Sdump(myVar1, myVar2, ...)
-
-Sample Dump Output
-
-See the Dump example for details on the setup of the types and variables being
-shown here.
-
- (main.Foo) {
- unexportedField: (*main.Bar)(0xf84002e210)({
- flag: (main.Flag) flagTwo,
- data: (uintptr)
- }),
- ExportedField: (map[interface {}]interface {}) (len=1) {
- (string) (len=3) "one": (bool) true
- }
- }
-
-Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
-command as shown.
- ([]uint8) (len=32 cap=32) {
- 00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
- 00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
- 00000020 31 32 |12|
- }
-
-Custom Formatter
-
-Spew provides a custom formatter that implements the fmt.Formatter interface
-so that it integrates cleanly with standard fmt package printing functions. The
-formatter is useful for inline printing of smaller data types similar to the
-standard %v format specifier.
-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations. Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting. In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Custom Formatter Usage
-
-The simplest way to make use of the spew custom formatter is to call one of the
-convenience functions such as spew.Printf, spew.Println, or spew.Printf. The
-functions have syntax you are most likely already familiar with:
-
- spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
- spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
- spew.Println(myVar, myVar2)
- spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
- spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-See the Index for the full list convenience functions.
-
-Sample Formatter Output
-
-Double pointer to a uint8:
- %v: <**>5
- %+v: <**>(0xf8400420d0->0xf8400420c8)5
- %#v: (**uint8)5
- %#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
-
-Pointer to circular struct with a uint8 field and a pointer to itself:
- %v: <*>{1 <*>}
- %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)}
- %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)}
- %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)}
-
-See the Printf example for details on the setup of variables being shown
-here.
-
-Errors
-
-Since it is possible for custom Stringer/error interfaces to panic, spew
-detects them and handles them internally by printing the panic information
-inline with the output. Since spew is intended to provide deep pretty printing
-capabilities on structures, it intentionally does not return any errors.

-NewFormatter returns a custom formatter that satisfies the fmt.Formatter

-types similar to the standard %v format specifier.
-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations. Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting. In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Typically this function shouldn't be called directly. It is much easier to make
-use of the custom formatter by calling one of the convenience functions such as
-Printf, Println, or Fprintf.

-## [1.5.5] - 2019-06-20
-
-* Introduce support for Go Modules
-
-## [1.5.3] - 2018-07-11
-Bug Fixes:
-* Fix a panic caused due to item.vptr not copying over vs.Value, when looking
- for a move key.
-
-## [1.5.2] - 2018-06-19
-Bug Fixes:
-* Fix the way move key gets generated.
-* If a transaction has unclosed, or multiple iterators running simultaneously,
- throw a panic. Every iterator must be properly closed. At any point in time,
- only one iterator per transaction can be running. This is to avoid bugs in a
- transaction data structure which is thread unsafe.
-
-* *Warning: This change might cause panics in user code. Fix is to properly
- close your iterators, and only have one running at a time per transaction.*
-
-## [1.5.1] - 2018-06-04
-Bug Fixes:
-* Fix for infinite yieldItemValue recursion. #503
-* Fix recursive addition of `badgerMove` prefix. https://github.com/dgraph-io/badger/commit/2e3a32f0ccac3066fb4206b28deb39c210c5266f
-* Use file size based window size for sampling, instead of fixing it to 10MB. #501
-
-Cleanup:
-* Clarify comments and documentation.
-* Move badger tool one directory level up.
-
-## [1.5.0] - 2018-05-08
-* Introduce `NumVersionsToKeep` option. This option is used to discard many
- versions of the same key, which saves space.
-* Add a new `SetWithDiscard` method, which would indicate that all the older
- versions of the key are now invalid. Those versions would be discarded during
- compactions.
-* Value log GC moves are now bound to another keyspace to ensure latest versions
- of data are always at the top in LSM tree.
-* Introduce `ValueLogMaxEntries` to restrict the number of key-value pairs per
- value log file. This helps bound the time it takes to garbage collect one
- file.
-
-## [1.4.0] - 2018-05-04
-* Make mmap-ing of value log optional.
-* Run GC multiple times, based on recorded discard statistics.
-* Add MergeOperator.
-* Force compact L0 on clsoe (#439).
-* Add truncate option to warn about data loss (#452).
-* Discard key versions during compaction (#464).
-* Introduce new `LSMOnlyOptions`, to make Badger act like a typical LSM based DB.
-
-Bug fix:
-* (Temporary) Check max version across all tables in Get (removed in next
- release).
-* Update commit and read ts while loading from backup.
-* Ensure all transaction entries are part of the same value log file.
-* On commit, run unlock callbacks before doing writes (#413).
-* Wait for goroutines to finish before closing iterators (#421).
-
-## [1.3.0] - 2017-12-12
-* Add `DB.NextSequence()` method to generate monotonically increasing integer
- sequences.
-* Add `DB.Size()` method to return the size of LSM and value log files.
-* Tweaked mmap code to make Windows 32-bit builds work.
-* Tweaked build tags on some files to make iOS builds work.
-* Fix `DB.PurgeOlderVersions()` to not violate some constraints.
-
-## [1.2.0] - 2017-11-30
-* Expose a `Txn.SetEntry()` method to allow setting the key-value pair
- and all the metadata at the same time.
-
-## [1.1.1] - 2017-11-28
-* Fix bug where txn.Get was returing key deleted in same transaction.
-* Fix race condition while decrementing reference in oracle.
-* Update doneCommit in the callback for CommitAsync.
-* Iterator see writes of current txn.
-
-## [1.1.0] - 2017-11-13
-* Create Badger directory if it does not exist when `badger.Open` is called.
-* Added `Item.ValueCopy()` to avoid deadlocks in long-running iterations
-* Fixed 64-bit alignment issues to make Badger run on Arm v7
-
-## [1.0.1] - 2017-11-06
-* Fix an uint16 overflow when resizing key slice

-
-
-
-BadgerDB is an embeddable, persistent and fast key-value (KV) database
-written in pure Go. It's meant to be a performant alternative to non-Go-based
-key-value stores like [RocksDB](https://github.com/facebook/rocksdb).
-
-## Project Status [Jun 26, 2019]
-
-Badger is stable and is being used to serve data sets worth hundreds of
-terabytes. Badger supports concurrent ACID transactions with serializable
-snapshot isolation (SSI) guarantees. A Jepsen-style bank test runs nightly for
-8h, with `--race` flag and ensures maintainance of transactional guarantees.
-Badger has also been tested to work with filesystem level anomalies, to ensure
-persistence and consistency.
-
-Badger v1.0 was released in Nov 2017, and the latest version that is data-compatible
-with v1.0 is v1.6.0.
-
-Badger v2.0, a new release coming up very soon will use a new storage format which won't
-be compatible with all of the v1.x. The [Changelog] is kept fairly up-to-date.
-
-For more details on our version naming schema please read [Choosing a version](#choosing-a-version).

-
-## Getting Started
-
-### Installing
-To start using Badger, install Go 1.11 or above and run `go get`:
-
-```sh
-$ go get github.com/dgraph-io/badger/...
-```
-
-This will retrieve the library and install the `badger` command line
-utility into your `$GOBIN` path.
-
-#### Choosing a version
-
-BadgerDB is a pretty special package from the point of view that the most important change we can
-make to it is not on its API but rather on how data is stored on disk.
-
-This is why we follow a version naming schema that differs from Semantic Versioning.
-
-- New major versions are released when the data format on disk changes in an incompatible way.
-- New minor versions are released whenever the API changes but data compatibility is maintained.
- Note that the changes on the API could be backward-incompatible - unlike Semantic Versioning.
-- New patch versions are released when there's no changes to the data format nor the API.
-
-Following these rules:
-
-- v1.5.0 and v1.6.0 can be used on top of the same files without any concerns, as their major
- version is the same, therefore the data format on disk is compatible.
-- v1.6.0 and v2.0.0 are data incompatible as their major version implies, so files created with
- v1.6.0 will need to be converted into the new format before they can be used by v2.0.0.
-
-For a longer explanation on the reasons behind using a new versioning naming schema, you can read
-[VERSIONING.md](VERSIONING.md).
-
-### Opening a database
-The top-level object in Badger is a `DB`. It represents multiple files on disk
-in specific directories, which contain the data for a single database.
-
-To open your database, use the `badger.Open()` function, with the appropriate
-options. The `Dir` and `ValueDir` options are mandatory and must be
-specified by the client. They can be set to the same value to simplify things.
-
-```go
-package main
-
-import (
- "log"
-
- badger "github.com/dgraph-io/badger"
-)
-
-func main() {
- // Open the Badger database located in the /tmp/badger directory.
- // It will be created if it doesn't exist.
- db, err := badger.Open(badger.DefaultOptions("tmp/badger"))
- if err != nil {
- log.Fatal(err)
- }
- defer db.Close()
- // Your code here…
-}
-```
-
-Please note that Badger obtains a lock on the directories so multiple processes
-cannot open the same database at the same time.
-
-### Transactions
-
-#### Read-only transactions
-To start a read-only transaction, you can use the `DB.View()` method:
-
-```go
-err := db.View(func(txn *badger.Txn) error {
- // Your code here…
- return nil
-})
-```
-
-You cannot perform any writes or deletes within this transaction. Badger
-ensures that you get a consistent view of the database within this closure. Any
-writes that happen elsewhere after the transaction has started, will not be
-seen by calls made within the closure.
-
-#### Read-write transactions
-To start a read-write transaction, you can use the `DB.Update()` method:
-
-```go
-err := db.Update(func(txn *badger.Txn) error {
- // Your code here…
- return nil
-})
-```
-
-All database operations are allowed inside a read-write transaction.
-
-Always check the returned error value. If you return an error
-within your closure it will be passed through.
-
-An `ErrConflict` error will be reported in case of a conflict. Depending on the state
-of your application, you have the option to retry the operation if you receive
-this error.
-
-An `ErrTxnTooBig` will be reported in case the number of pending writes/deletes in
-the transaction exceed a certain limit. In that case, it is best to commit the
-transaction and start a new transaction immediately. Here is an example (we are
-not checking for errors in some places for simplicity):
-
-```go
-updates := make(map[string]string)
-txn := db.NewTransaction(true)
-for k,v := range updates {
- if err := txn.Set([]byte(k),[]byte(v)); err == ErrTxnTooBig {
- _ = txn.Commit()
- txn = db.NewTransaction(true)
- _ = txn.Set([]byte(k),[]byte(v))
- }
-}
-_ = txn.Commit()
-```
-
-#### Managing transactions manually
-The `DB.View()` and `DB.Update()` methods are wrappers around the
-`DB.NewTransaction()` and `Txn.Commit()` methods (or `Txn.Discard()` in case of
-read-only transactions). These helper methods will start the transaction,
-execute a function, and then safely discard your transaction if an error is
-returned. This is the recommended way to use Badger transactions.
-
-However, sometimes you may want to manually create and commit your
-transactions. You can use the `DB.NewTransaction()` function directly, which
-takes in a boolean argument to specify whether a read-write transaction is
-required. For read-write transactions, it is necessary to call `Txn.Commit()`
-to ensure the transaction is committed. For read-only transactions, calling
-`Txn.Discard()` is sufficient. `Txn.Commit()` also calls `Txn.Discard()`
-internally to cleanup the transaction, so just calling `Txn.Commit()` is
-sufficient for read-write transaction. However, if your code doesn’t call
-`Txn.Commit()` for some reason (for e.g it returns prematurely with an error),
-then please make sure you call `Txn.Discard()` in a `defer` block. Refer to the
-code below.
-
-```go
-// Start a writable transaction.
-txn := db.NewTransaction(true)
-defer txn.Discard()
-
-// Use the transaction...
-err := txn.Set([]byte("answer"), []byte("42"))
-if err != nil {
- return err
-}
-
-// Commit the transaction and check for error.
-if err := txn.Commit(); err != nil {
- return err
-}
-```
-
-The first argument to `DB.NewTransaction()` is a boolean stating if the transaction
-should be writable.
-
-Badger allows an optional callback to the `Txn.Commit()` method. Normally, the
-callback can be set to `nil`, and the method will return after all the writes
-have succeeded. However, if this callback is provided, the `Txn.Commit()`
-method returns as soon as it has checked for any conflicts. The actual writing
-to the disk happens asynchronously, and the callback is invoked once the
-writing has finished, or an error has occurred. This can improve the throughput
-of the application in some cases. But it also means that a transaction is not
-durable until the callback has been invoked with a `nil` error value.
-
-### Using key/value pairs
-To save a key/value pair, use the `Txn.Set()` method:
-
-```go
-err := db.Update(func(txn *badger.Txn) error {
- err := txn.Set([]byte("answer"), []byte("42"))
- return err
-})
-```
-
-Key/Value pair can also be saved by first creating `Entry`, then setting this
-`Entry` using `Txn.SetEntry()`. `Entry` also exposes methods to set properties
-on it.
-
-```go
-err := db.Update(func(txn *badger.Txn) error {
- e := NewEntry([]byte("answer"), []byte("42"))
- err := txn.SetEntry(e)
- return err
-})
-```
-
-This will set the value of the `"answer"` key to `"42"`. To retrieve this
-value, we can use the `Txn.Get()` method:
-
-```go
-err := db.View(func(txn *badger.Txn) error {
- item, err := txn.Get([]byte("answer"))
- handle(err)
-
- var valNot, valCopy []byte
- err := item.Value(func(val []byte) error {
- // This func with val would only be called if item.Value encounters no error.
-
- // Accessing val here is valid.
- fmt.Printf("The answer is: %s\n", val)
-
- // Copying or parsing val is valid.
- valCopy = append([]byte{}, val...)
-
- // Assigning val slice to another variable is NOT OK.
- valNot = val // Do not do this.
- return nil
- })
- handle(err)
-
- // DO NOT access val here. It is the most common cause of bugs.
- fmt.Printf("NEVER do this. %s\n", valNot)
-
- // You must copy it to use it outside item.Value(...).
- fmt.Printf("The answer is: %s\n", valCopy)
-
- // Alternatively, you could also use item.ValueCopy().
- valCopy, err = item.ValueCopy(nil)
- handle(err)
- fmt.Printf("The answer is: %s\n", valCopy)
-
- return nil
-})
-```
-
-`Txn.Get()` returns `ErrKeyNotFound` if the value is not found.
-
-Please note that values returned from `Get()` are only valid while the
-transaction is open. If you need to use a value outside of the transaction
-then you must use `copy()` to copy it to another byte slice.
-
-Use the `Txn.Delete()` method to delete a key.
-
-### Monotonically increasing integers
-
-To get unique monotonically increasing integers with strong durability, you can
-use the `DB.GetSequence` method. This method returns a `Sequence` object, which
-is thread-safe and can be used concurrently via various goroutines.
-
-Badger would lease a range of integers to hand out from memory, with the
-bandwidth provided to `DB.GetSequence`. The frequency at which disk writes are
-done is determined by this lease bandwidth and the frequency of `Next`
-invocations. Setting a bandwith too low would do more disk writes, setting it
-too high would result in wasted integers if Badger is closed or crashes.
-To avoid wasted integers, call `Release` before closing Badger.
-
-```go
-seq, err := db.GetSequence(key, 1000)
-defer seq.Release()
-for {
- num, err := seq.Next()
-}
-```
-
-### Merge Operations
-Badger provides support for ordered merge operations. You can define a func
-of type `MergeFunc` which takes in an existing value, and a value to be
-_merged_ with it. It returns a new value which is the result of the _merge_
-operation. All values are specified in byte arrays. For e.g., here is a merge
-function (`add`) which appends a `[]byte` value to an existing `[]byte` value.
-
-```Go
-// Merge function to append one byte slice to another
-func add(originalValue, newValue []byte) []byte {
- return append(originalValue, newValue...)
-}
-```
-
-This function can then be passed to the `DB.GetMergeOperator()` method, along
-with a key, and a duration value. The duration specifies how often the merge
-function is run on values that have been added using the `MergeOperator.Add()`
-method.
-
-`MergeOperator.Get()` method can be used to retrieve the cumulative value of the key
-associated with the merge operation.
-
-```Go
-key := []byte("merge")
-
-m := db.GetMergeOperator(key, add, 200*time.Millisecond)
-defer m.Stop()
-
-m.Add([]byte("A"))
-m.Add([]byte("B"))
-m.Add([]byte("C"))
-
-res, _ := m.Get() // res should have value ABC encoded
-```
-
-Example: Merge operator which increments a counter
-
-```Go
-func uint64ToBytes(i uint64) []byte {
- var buf [8]byte
- binary.BigEndian.PutUint64(buf[:], i)
- return buf[:]
-}
-
-func bytesToUint64(b []byte) uint64 {
- return binary.BigEndian.Uint64(b)
-}
-
-// Merge function to add two uint64 numbers
-func add(existing, new []byte) []byte {
- return uint64ToBytes(bytesToUint64(existing) + bytesToUint64(new))
-}
-```
-It can be used as
-```Go
-key := []byte("merge")
-
-m := db.GetMergeOperator(key, add, 200*time.Millisecond)
-defer m.Stop()
-
-m.Add(uint64ToBytes(1))
-m.Add(uint64ToBytes(2))
-m.Add(uint64ToBytes(3))
-
-res, _ := m.Get() // res should have value 6 encoded
-```
-
-### Setting Time To Live(TTL) and User Metadata on Keys
-Badger allows setting an optional Time to Live (TTL) value on keys. Once the TTL has
-elapsed, the key will no longer be retrievable and will be eligible for garbage
-collection. A TTL can be set as a `time.Duration` value using the `Entry.WithTTL()`
-and `Txn.SetEntry()` API methods.
-
-```go
-err := db.Update(func(txn *badger.Txn) error {
- e := NewEntry([]byte("answer"), []byte("42")).WithTTL(time.Hour)
- err := txn.SetEntry(e)
- return err
-})
-```
-
-An optional user metadata value can be set on each key. A user metadata value
-is represented by a single byte. It can be used to set certain bits along
-with the key to aid in interpreting or decoding the key-value pair. User
-metadata can be set using `Entry.WithMeta()` and `Txn.SetEntry()` API methods.
-
-```go
-err := db.Update(func(txn *badger.Txn) error {
- e := NewEntry([]byte("answer"), []byte("42")).WithMeta(byte(1))
- err := txn.SetEntry(e)
- return err
-})
-```
-
-`Entry` APIs can be used to add the user metadata and TTL for same key. This `Entry`
-then can be set using `Txn.SetEntry()`.
-
-```go
-err := db.Update(func(txn *badger.Txn) error {
- e := NewEntry([]byte("answer"), []byte("42")).WithMeta(byte(1)).WithTTL(time.Hour)
- err := txn.SetEntry(e)
- return err
-})
-```
-
-### Iterating over keys
-To iterate over keys, we can use an `Iterator`, which can be obtained using the
-`Txn.NewIterator()` method. Iteration happens in byte-wise lexicographical sorting
-order.
-
-
-```go
-err := db.View(func(txn *badger.Txn) error {
- opts := badger.DefaultIteratorOptions
- opts.PrefetchSize = 10
- it := txn.NewIterator(opts)
- defer it.Close()
- for it.Rewind(); it.Valid(); it.Next() {
- item := it.Item()
- k := item.Key()
- err := item.Value(func(v []byte) error {
- fmt.Printf("key=%s, value=%s\n", k, v)
- return nil
- })
- if err != nil {
- return err
- }
- }
- return nil
-})
-```
-
-The iterator allows you to move to a specific point in the list of keys and move
-forward or backward through the keys one at a time.
-
-By default, Badger prefetches the values of the next 100 items. You can adjust
-that with the `IteratorOptions.PrefetchSize` field. However, setting it to
-a value higher than GOMAXPROCS (which we recommend to be 128 or higher)
-shouldn’t give any additional benefits. You can also turn off the fetching of
-values altogether. See section below on key-only iteration.
-
-#### Prefix scans
-To iterate over a key prefix, you can combine `Seek()` and `ValidForPrefix()`:
-
-```go
-db.View(func(txn *badger.Txn) error {
- it := txn.NewIterator(badger.DefaultIteratorOptions)
- defer it.Close()
- prefix := []byte("1234")
- for it.Seek(prefix); it.ValidForPrefix(prefix); it.Next() {
- item := it.Item()
- k := item.Key()
- err := item.Value(func(v []byte) error {
- fmt.Printf("key=%s, value=%s\n", k, v)
- return nil
- })
- if err != nil {
- return err
- }
- }
- return nil
-})
-```
-
-#### Key-only iteration
-Badger supports a unique mode of iteration called _key-only_ iteration. It is
-several order of magnitudes faster than regular iteration, because it involves
-access to the LSM-tree only, which is usually resident entirely in RAM. To
-enable key-only iteration, you need to set the `IteratorOptions.PrefetchValues`
-field to `false`. This can also be used to do sparse reads for selected keys
-during an iteration, by calling `item.Value()` only when required.
-
-```go
-err := db.View(func(txn *badger.Txn) error {
- opts := badger.DefaultIteratorOptions
- opts.PrefetchValues = false
- it := txn.NewIterator(opts)
- defer it.Close()
- for it.Rewind(); it.Valid(); it.Next() {
- item := it.Item()
- k := item.Key()
- fmt.Printf("key=%s\n", k)
- }
- return nil
-})
-```
-
-### Stream
-Badger provides a Stream framework, which concurrently iterates over all or a
-portion of the DB, converting data into custom key-values, and streams it out
-serially to be sent over network, written to disk, or even written back to
-Badger. This is a lot faster way to iterate over Badger than using a single
-Iterator. Stream supports Badger in both managed and normal mode.
-
-Stream uses the natural boundaries created by SSTables within the LSM tree, to
-quickly generate key ranges. Each goroutine then picks a range and runs an
-iterator to iterate over it. Each iterator iterates over all versions of values
-and is created from the same transaction, thus working over a snapshot of the
-DB. Every time a new key is encountered, it calls `ChooseKey(item)`, followed
-by `KeyToList(key, itr)`. This allows a user to select or reject that key, and
-if selected, convert the value versions into custom key-values. The goroutine
-batches up 4MB worth of key-values, before sending it over to a channel.
-Another goroutine further batches up data from this channel using *smart
-batching* algorithm and calls `Send` serially.
-
-This framework is designed for high throughput key-value iteration, spreading
-the work of iteration across many goroutines. `DB.Backup` uses this framework to
-provide full and incremental backups quickly. Dgraph is a heavy user of this
-framework. In fact, this framework was developed and used within Dgraph, before
-getting ported over to Badger.
-
-```go
-stream := db.NewStream()
-// db.NewStreamAt(readTs) for managed mode.
-
-// -- Optional settings
-stream.NumGo = 16 // Set number of goroutines to use for iteration.
-stream.Prefix = []byte("some-prefix") // Leave nil for iteration over the whole DB.
-stream.LogPrefix = "Badger.Streaming" // For identifying stream logs. Outputs to Logger.
-
-// ChooseKey is called concurrently for every key. If left nil, assumes true by default.
-stream.ChooseKey = func(item *badger.Item) bool {
- return bytes.HasSuffix(item.Key(), []byte("er"))
-}
-
-// KeyToList is called concurrently for chosen keys. This can be used to convert
-// Badger data into custom key-values. If nil, uses stream.ToList, a default
-// implementation, which picks all valid key-values.
-stream.KeyToList = nil
-
-// -- End of optional settings.
-
-// Send is called serially, while Stream.Orchestrate is running.
-stream.Send = func(list *pb.KVList) error {
- return proto.MarshalText(w, list) // Write to w.
-}
-
-// Run the stream
-if err := stream.Orchestrate(context.Background()); err != nil {
- return err
-}
-// Done.
-```
-
-### Garbage Collection
-Badger values need to be garbage collected, because of two reasons:
-
-* Badger keeps values separately from the LSM tree. This means that the compaction operations
-that clean up the LSM tree do not touch the values at all. Values need to be cleaned up
-separately.
-
-* Concurrent read/write transactions could leave behind multiple values for a single key, because they
-are stored with different versions. These could accumulate, and take up unneeded space beyond the
-time these older versions are needed.
-
-Badger relies on the client to perform garbage collection at a time of their choosing. It provides
-the following method, which can be invoked at an appropriate time:
-
-* `DB.RunValueLogGC()`: This method is designed to do garbage collection while
- Badger is online. Along with randomly picking a file, it uses statistics generated by the
- LSM-tree compactions to pick files that are likely to lead to maximum space
- reclamation. It is recommended to be called during periods of low activity in
- your system, or periodically. One call would only result in removal of at max
- one log file. As an optimization, you could also immediately re-run it whenever
- it returns nil error (indicating a successful value log GC), as shown below.
-
- ```go
- ticker := time.NewTicker(5 * time.Minute)
- defer ticker.Stop()
- for range ticker.C {
- again:
- err := db.RunValueLogGC(0.7)
- if err == nil {
- goto again
- }
- }
- ```
-
-* `DB.PurgeOlderVersions()`: This method is **DEPRECATED** since v1.5.0. Now, Badger's LSM tree automatically discards older/invalid versions of keys.
-
-**Note: The RunValueLogGC method would not garbage collect the latest value log.**
-
-### Database backup
-There are two public API methods `DB.Backup()` and `DB.Load()` which can be
-used to do online backups and restores. Badger v0.9 provides a CLI tool
-`badger`, which can do offline backup/restore. Make sure you have `$GOPATH/bin`
-in your PATH to use this tool.
-
-The command below will create a version-agnostic backup of the database, to a
-file `badger.bak` in the current working directory
-
-```
-badger backup --dir
-```
-
-To restore `badger.bak` in the current working directory to a new database:
-
-```
-badger restore --dir
-```
-
-See `badger --help` for more details.
-
-If you have a Badger database that was created using v0.8 (or below), you can
-use the `badger_backup` tool provided in v0.8.1, and then restore it using the
-command above to upgrade your database to work with the latest version.
-
-```
-badger_backup --dir --backup-file badger.bak
-```
-
-We recommend all users to use the `Backup` and `Restore` APIs and tools. However,
-Badger is also rsync-friendly because all files are immutable, barring the
-latest value log which is append-only. So, rsync can be used as rudimentary way
-to perform a backup. In the following script, we repeat rsync to ensure that the
-LSM tree remains consistent with the MANIFEST file while doing a full backup.
-
-```
-#!/bin/bash
-set -o history
-set -o histexpand
-# Makes a complete copy of a Badger database directory.
-# Repeat rsync if the MANIFEST and SSTables are updated.
-rsync -avz --delete db/ dst
-while !! | grep -q "(MANIFEST\|\.sst)$"; do :; done
-```
-
-### Memory usage
-Badger's memory usage can be managed by tweaking several options available in
-the `Options` struct that is passed in when opening the database using
-`DB.Open`.
-
-- `Options.ValueLogLoadingMode` can be set to `options.FileIO` (instead of the
- default `options.MemoryMap`) to avoid memory-mapping log files. This can be
- useful in environments with low RAM.
-- Number of memtables (`Options.NumMemtables`)
- - If you modify `Options.NumMemtables`, also adjust `Options.NumLevelZeroTables` and
- `Options.NumLevelZeroTablesStall` accordingly.
-- Number of concurrent compactions (`Options.NumCompactors`)
-- Mode in which LSM tree is loaded (`Options.TableLoadingMode`)
-- Size of table (`Options.MaxTableSize`)
-- Size of value log file (`Options.ValueLogFileSize`)
-
-If you want to decrease the memory usage of Badger instance, tweak these
-options (ideally one at a time) until you achieve the desired
-memory usage.
-
-### Statistics
-Badger records metrics using the [expvar] package, which is included in the Go
-standard library. All the metrics are documented in [y/metrics.go][metrics]
-file.
-
-`expvar` package adds a handler in to the default HTTP server (which has to be
-started explicitly), and serves up the metrics at the `/debug/vars` endpoint.
-These metrics can then be collected by a system like [Prometheus], to get
-better visibility into what Badger is doing.

-## Design
-Badger was written with these design goals in mind:
-
-- Write a key-value database in pure Go.
-- Use latest research to build the fastest KV database for data sets spanning terabytes.
-- Optimize for SSDs.
-
-Badger’s design is based on a paper titled _[WiscKey: Separating Keys from
-Values in SSD-conscious Storage][wisckey]_.

-## Frequently Asked Questions
-- **My writes are getting stuck. Why?**
-
-**Update: With the new `Value(func(v []byte))` API, this deadlock can no longer
-happen.**
-
-The following is true for users on Badger v1.x.
-
-This can happen if a long running iteration with `Prefetch` is set to false, but
-a `Item::Value` call is made internally in the loop. That causes Badger to
-acquire read locks over the value log files to avoid value log GC removing the
-file from underneath. As a side effect, this also blocks a new value log GC
-file from being created, when the value log file boundary is hit.
-
-Please see Github issues [#293](https://github.com/dgraph-io/badger/issues/293)
-and [#315](https://github.com/dgraph-io/badger/issues/315).
-
-There are multiple workarounds during iteration:
-
-1. Use `Item::ValueCopy` instead of `Item::Value` when retrieving value.
-1. Set `Prefetch` to true. Badger would then copy over the value and release the
- file lock immediately.
-1. When `Prefetch` is false, don't call `Item::Value` and do a pure key-only
- iteration. This might be useful if you just want to delete a lot of keys.
-1. Do the writes in a separate transaction after the reads.
-
-- **My writes are really slow. Why?**
-
-Are you creating a new transaction for every single key update, and waiting for
-it to `Commit` fully before creating a new one? This will lead to very low
-throughput.
-
-We have created `WriteBatch` API which provides a way to batch up
-many updates into a single transaction and `Commit` that transaction using
-callbacks to avoid blocking. This amortizes the cost of a transaction really
-well, and provides the most efficient way to do bulk writes.
-
-```go
-wb := db.NewWriteBatch()
-defer wb.Cancel()
-
-for i := 0; i < N; i++ {
- err := wb.Set(key(i), value(i), 0) // Will create txns as needed.
- handle(err)
-}
-handle(wb.Flush()) // Wait for all txns to finish.
-```
-
-Note that `WriteBatch` API does not allow any reads. For read-modify-write
-workloads, you should be using the `Transaction` API.
-
-- **I don't see any disk write. Why?**
-
-If you're using Badger with `SyncWrites=false`, then your writes might not be written to value log
-and won't get synced to disk immediately. Writes to LSM tree are done inmemory first, before they
-get compacted to disk. The compaction would only happen once `MaxTableSize` has been reached. So, if
-you're doing a few writes and then checking, you might not see anything on disk. Once you `Close`
-the database, you'll see these writes on disk.
-
-- **Reverse iteration doesn't give me the right results.**
-
-Just like forward iteration goes to the first key which is equal or greater than the SEEK key, reverse iteration goes to the first key which is equal or lesser than the SEEK key. Therefore, SEEK key would not be part of the results. You can typically add a `0xff` byte as a suffix to the SEEK key to include it in the results. See the following issues: [#436](https://github.com/dgraph-io/badger/issues/436) and [#347](https://github.com/dgraph-io/badger/issues/347).
-
-- **Which instances should I use for Badger?**
-
-We recommend using instances which provide local SSD storage, without any limit
-on the maximum IOPS. In AWS, these are storage optimized instances like i3. They
-provide local SSDs which clock 100K IOPS over 4KB blocks easily.
-
-- **I'm getting a closed channel error. Why?**
-
-```
-panic: close of closed channel
-panic: send on closed channel
-```
-
-If you're seeing panics like above, this would be because you're operating on a closed DB. This can happen, if you call `Close()` before sending a write, or multiple times. You should ensure that you only call `Close()` once, and all your read/write operations finish before closing.
-
-- **Are there any Go specific settings that I should use?**
-
-We *highly* recommend setting a high number for GOMAXPROCS, which allows Go to
-observe the full IOPS throughput provided by modern SSDs. In Dgraph, we have set
-it to 128. For more details, [see this
-thread](https://groups.google.com/d/topic/golang-nuts/jPb_h3TvlKE/discussion).
-
-- **Are there any linux specific settings that I should use?**
-
-We recommend setting max file descriptors to a high number depending upon the expected size of you data.

-# Serialization Versioning: Semantic Versioning for databases
-
-Semantic Versioning, commonly known as SemVer, is a great idea that has been very widely adopted as
-a way to decide how to name software versions. The whole concept is very well summarized on
-semver.org with the following lines:
-
-> Given a version number MAJOR.MINOR.PATCH, increment the:
->
-> 1. MAJOR version when you make incompatible API changes,
-> 2. MINOR version when you add functionality in a backwards-compatible manner, and
-> 3. PATCH version when you make backwards-compatible bug fixes.
->
-> Additional labels for pre-release and build metadata are available as extensions to the
-> MAJOR.MINOR.PATCH format.
-
-Unfortunately, API changes are not the most important changes for libraries that serialize data for
-later consumption. For these libraries, such as BadgerDB, changes to the API are much easier to
-handle than change to the data format used to store data on disk.
-
-## Serialization Version specification
-
-Serialization Versioning, like Semantic Versioning, uses 3 numbers and also calls them
-MAJOR.MINOR.PATCH, but the semantics of the numbers are slightly modified:
-
-Given a version number MAJOR.MINOR.PATCH, increment the:
-
-- MAJOR version when you make changes that require a transformation of the dataset before it can be
-used again.
-- MINOR version when old datasets are still readable but the API might have changed in
-backwards-compatible or incompatible ways.
-- PATCH version when you make backwards-compatible bug fixes.
-
-Additional labels for pre-release and build metadata are available as extensions to the
-MAJOR.MINOR.PATCH format.
-
-Following this naming strategy, migration from v1.x to v2.x requires a migration strategy for your
-existing dataset, and as such has to be carefully planned. Migrations in between different minor
-versions (e.g. v1.5.x and v1.6.x) might break your build, as the API *might* have changed, but once
-your code compiles there's no need for any data migration. Lastly, changes in between two different
-patch versions should never break your build or dataset.
-
-For more background on our decision to adopt Serialization Versioning, read the blog post
-[Semantic Versioning, Go Modules, and Databases][blog] and the original proposal on
-[this comment on Dgraph's Discuss forum][discuss].

-/*
-Package badger implements an embeddable, simple and fast key-value database,
-written in pure Go. It is designed to be highly performant for both reads and
-writes simultaneously. Badger uses Multi-Version Concurrency Control (MVCC), and
-supports transactions. It runs transactions concurrently, with serializable
-snapshot isolation guarantees.
-
-Badger uses an LSM tree along with a value log to separate keys from values,
-hence reducing both write amplification and the size of the LSM tree. This
-allows LSM tree to be served entirely from RAM, while the values are served
-from SSD.
-
-
-Usage
-
-Badger has the following main types: DB, Txn, Item and Iterator. DB contains
-keys that are associated with values. It must be opened with the appropriate
-options before it can be accessed.
-
-All operations happen inside a Txn. Txn represents a transaction, which can
-be read-only or read-write. Read-only transactions can read values for a
-given key (which are returned inside an Item), or iterate over a set of
-key-value pairs using an Iterator (which are returned as Item type values as
-well). Read-write transactions can also update and delete keys from the DB.
-
-See the examples for more usage details.

-Adapted from RocksDB inline skiplist.
-
-Key differences:
-- No optimization for sequential inserts (no "prev").
-- No custom comparator.
-- Support overwrites. This requires care when we see the same key when inserting.
- For RocksDB or LevelDB, overwrites are implemented as a newer sequence number in the key, so
- there is no need for values. We don't intend to support versioning. In-place updates of values
- would be more efficient.
-- We discard all non-concurrent code.
-- We do not support Splices. This simplifies the code a lot.
-- No AllocateNode or other pointer arithmetic.
-- We combine the findLessThan, findGreaterOrEqual, etc into one function.

-// Some common use cases are:
-// (1) You receive an error from external lib, and would like to check/log fatal.
-// For this, use x.Check, x.Checkf. These will check for err != nil, which is
-// more common in Go. If you want to check for boolean being true, use
-// x.Assert, x.Assertf.
-// (2) You receive an error from external lib, and would like to pass on with some
-// stack trace information. In this case, use x.Wrap or x.Wrapf.
-// (3) You want to generate a new error with stack trace info. Use x.Errorf.

-*Google's FarmHash hash functions implemented in Go*
-
-[](https://github.com/dgryski/go-farm/tree/master)
-[](https://travis-ci.org/dgryski/go-farm?branch=master)
-[](https://coveralls.io/github/dgryski/go-farm?branch=master)

-
-## Description
-
-FarmHash, a family of hash functions.
-
-This is a (mechanical) translation of the non-SSE4/non-AESNI hash functions from Google's FarmHash (https://github.com/google/farmhash).
-
-
-FarmHash provides hash functions for strings and other data.
-The functions mix the input bits thoroughly but are not suitable for cryptography.
-
-All members of the FarmHash family were designed with heavy reliance on previous work by Jyrki Alakuijala, Austin Appleby, Bob Jenkins, and others.
-
-For more information please consult https://github.com/google/farmhash
-
-
-## Getting started
-
-This application is written in Go language, please refer to the guides in https://golang.org for getting started.
-
-This project include a Makefile that allows you to test and build the project with simple commands.
-To see all available options:
-```bash
-make help
-```
-
-## Running all tests
-
-Before committing the code, please check if it passes all tests using
-```bash
-make qa
-```

-# Humane Units [](https://travis-ci.org/dustin/go-humanize) [](https://godoc.org/github.com/dustin/go-humanize)
-
-Just a few functions for helping humanize times and sizes.
-
-`go get` it as `github.com/dustin/go-humanize`, import it as
-`"github.com/dustin/go-humanize"`, use it as `humanize`.
-
-See [godoc](https://godoc.org/github.com/dustin/go-humanize) for
-complete documentation.
-
-## Sizes
-
-This lets you take numbers like `82854982` and convert them to useful
-strings like, `83 MB` or `79 MiB` (whichever you prefer).
-
-Example:
-
-```go
-fmt.Printf("That file is %s.", humanize.Bytes(82854982)) // That file is 83 MB.
-```
-
-## Times
-
-This lets you take a `time.Time` and spit it out in relative terms.
-For example, `12 seconds ago` or `3 days from now`.
-
-Example:
-
-```go
-fmt.Printf("This was touched %s.", humanize.Time(someTimeInstance)) // This was touched 7 hours ago.
-```
-
-Thanks to Kyle Lemons for the time implementation from an IRC
-conversation one day. It's pretty neat.
-
-## Ordinals
-
-From a [mailing list discussion][odisc] where a user wanted to be able
-to label ordinals.
-
- 0 -> 0th
- 1 -> 1st
- 2 -> 2nd
- 3 -> 3rd
- 4 -> 4th
- [...]
-
-Example:
-
-```go
-fmt.Printf("You're my %s best friend.", humanize.Ordinal(193)) // You are my 193rd best friend.
-```
-
-## Commas
-
-Want to shove commas into numbers? Be my guest.
-
- 0 -> 0
- 100 -> 100
- 1000 -> 1,000
- 1000000000 -> 1,000,000,000
- -100000 -> -100,000
-
-Example:
-
-```go
-fmt.Printf("You owe $%s.\n", humanize.Comma(6582491)) // You owe $6,582,491.
-```
-
-## Ftoa
-
-Nicer float64 formatter that removes trailing zeros.
-
-```go
-fmt.Printf("%f", 2.24) // 2.240000
-fmt.Printf("%s", humanize.Ftoa(2.24)) // 2.24
-fmt.Printf("%f", 2.0) // 2.000000
-fmt.Printf("%s", humanize.Ftoa(2.0)) // 2
-```
-
-## SI notation
-
-Format numbers with [SI notation][sinotation].
-
-Example:
-
-```go
-humanize.SI(0.00000000223, "M") // 2.23 nM
-```
-
-## English-specific functions
-
-The following functions are in the `humanize/english` subpackage.
-
-### Plurals
-
-Simple English pluralization
-
-```go
-english.PluralWord(1, "object", "") // object
-english.PluralWord(42, "object", "") // objects
-english.PluralWord(2, "bus", "") // buses
-english.PluralWord(99, "locus", "loci") // loci
-
-english.Plural(1, "object", "") // 1 object
-english.Plural(42, "object", "") // 42 objects
-english.Plural(2, "bus", "") // 2 buses
-english.Plural(99, "locus", "loci") // 99 loci
-```
-
-### Word series
-
-Format comma-separated words lists with conjuctions:
-
-```go
-english.WordSeries([]string{"foo"}, "and") // foo
-english.WordSeries([]string{"foo", "bar"}, "and") // foo and bar
-english.WordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar and baz
-
-english.OxfordWordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar, and baz
-```

-## [8.11.4](https://github.com/go-redis/redis/compare/v8.11.3...v8.11.4) (2021-10-04)
-
-
-### Features
-
-* add acl auth support for sentinels ([f66582f](https://github.com/go-redis/redis/commit/f66582f44f3dc3a4705a5260f982043fde4aa634))

-
-
-
-## v8.11
-
-- Remove OpenTelemetry metrics.
-- Supports more redis commands and options.
-
-## v8.10
-
-- Removed extra OpenTelemetry spans from go-redis core. Now go-redis instrumentation only adds a
- single span with a Redis command (instead of 4 spans). There are multiple reasons behind this
- decision:
-
- - Traces become smaller and less noisy.
- - It may be costly to process those 3 extra spans for each query.
- - go-redis no longer depends on OpenTelemetry.
-
- Eventually we hope to replace the information that we no longer collect with OpenTelemetry
- Metrics.
-
-## v8.9
-
-- Changed `PubSub.Channel` to only rely on `Ping` result. You can now use `WithChannelSize`,
- `WithChannelHealthCheckInterval`, and `WithChannelSendTimeout` to override default settings.
-
-## v8.8
-
-- To make updating easier, extra modules now have the same version as go-redis does. That means that
- you need to update your imports:
-
-```
-github.com/go-redis/redis/extra/redisotel -> github.com/go-redis/redis/extra/redisotel/v8
-github.com/go-redis/redis/extra/rediscensus -> github.com/go-redis/redis/extra/rediscensus/v8
-```
-
-## v8.5
-
-- [knadh](https://github.com/knadh) contributed long-awaited ability to scan Redis Hash into a
- struct:
-
-```go
-err := rdb.HGetAll(ctx, "hash").Scan(&data)
-
-err := rdb.MGet(ctx, "key1", "key2").Scan(&data)
-```
-
-- Please check [redismock](https://github.com/go-redis/redismock) by
- [monkey92t](https://github.com/monkey92t) if you are looking for mocking Redis Client.
-
-## v8
-
-- All commands require `context.Context` as a first argument, e.g. `rdb.Ping(ctx)`. If you are not
- using `context.Context` yet, the simplest option is to define global package variable
- `var ctx = context.TODO()` and use it when `ctx` is required.
-
-- Full support for `context.Context` canceling.
-
-- Added `redis.NewFailoverClusterClient` that supports routing read-only commands to a slave node.
-
-- Added `redisext.OpenTemetryHook` that adds
- [Redis OpenTelemetry instrumentation](https://redis.uptrace.dev/tracing/).
-
-- Redis slow log support.
-
-- Ring uses Rendezvous Hashing by default which provides better distribution. You need to move
- existing keys to a new location or keys will be inaccessible / lost. To use old hashing scheme:
-
-```go
-import "github.com/golang/groupcache/consistenthash"
-
-ring := redis.NewRing(&redis.RingOptions{
- NewConsistentHash: func() {
- return consistenthash.New(100, crc32.ChecksumIEEE)
- },
-})
-```
-
-- `ClusterOptions.MaxRedirects` default value is changed from 8 to 3.
-- `Options.MaxRetries` default value is changed from 0 to 3.
-
-- `Cluster.ForEachNode` is renamed to `ForEachShard` for consistency with `Ring`.
-
-## v7.3
-
-- New option `Options.Username` which causes client to use `AuthACL`. Be aware if your connection
- URL contains username.
-
-## v7.2
-
-- Existing `HMSet` is renamed to `HSet` and old deprecated `HMSet` is restored for Redis 3 users.
-
-## v7.1
-
-- Existing `Cmd.String` is renamed to `Cmd.Text`. New `Cmd.String` implements `fmt.Stringer`
- interface.
-
-## v7
-
-- _Important_. Tx.Pipeline now returns a non-transactional pipeline. Use Tx.TxPipeline for a
- transactional pipeline.
-- WrapProcess is replaced with more convenient AddHook that has access to context.Context.
-- WithContext now can not be used to create a shallow copy of the client.
-- New methods ProcessContext, DoContext, and ExecContext.
-- Client respects Context.Deadline when setting net.Conn deadline.
-- Client listens on Context.Done while waiting for a connection from the pool and returns an error
- when context context is cancelled.
-- Add PubSub.ChannelWithSubscriptions that sends `*Subscription` in addition to `*Message` to allow
- detecting reconnections.
-- `time.Time` is now marshalled in RFC3339 format. `rdb.Get("foo").Time()` helper is added to parse
- the time.
-- `SetLimiter` is removed and added `Options.Limiter` instead.
-- `HMSet` is deprecated as of Redis v4.
-
-## v6.15
-
-- Cluster and Ring pipelines process commands for each node in its own goroutine.
-
-## 6.14
-
-- Added Options.MinIdleConns.
-- Added Options.MaxConnAge.
-- PoolStats.FreeConns is renamed to PoolStats.IdleConns.
-- Add Client.Do to simplify creating custom commands.
-- Add Cmd.String, Cmd.Int, Cmd.Int64, Cmd.Uint64, Cmd.Float64, and Cmd.Bool helpers.
-- Lower memory usage.
-
-## v6.13
-
-- Ring got new options called `HashReplicas` and `Hash`. It is recommended to set
- `HashReplicas = 1000` for better keys distribution between shards.
-- Cluster client was optimized to use much less memory when reloading cluster state.
-- PubSub.ReceiveMessage is re-worked to not use ReceiveTimeout so it does not lose data when timeout
- occurres. In most cases it is recommended to use PubSub.Channel instead.
-- Dialer.KeepAlive is set to 5 minutes by default.
-
-## v6.12
-
-- ClusterClient got new option called `ClusterSlots` which allows to build cluster of normal Redis
- Servers that don't have cluster mode enabled. See
- https://godoc.org/github.com/go-redis/redis#example-NewClusterClient--ManualSetup

-
-## Installation
-
-go-redis supports 2 last Go versions and requires a Go version with
-[modules](https://github.com/golang/go/wiki/Modules) support. So make sure to initialize a Go
-module:
-
-```shell
-go mod init github.com/my/repo
-```
-
-And then install go-redis/v8 (note _v8_ in the import; omitting it is a popular mistake):
-
-```shell
-go get github.com/go-redis/redis/v8
-```
-
-## Quickstart
-
-```go
-import (
- "context"
- "github.com/go-redis/redis/v8"
- "fmt"
-)
-
-var ctx = context.Background()
-
-func ExampleClient() {
- rdb := redis.NewClient(&redis.Options{
- Addr: "localhost:6379",
- Password: "", // no password set
- DB: 0, // use default DB
- })
-
- err := rdb.Set(ctx, "key", "value", 0).Err()
- if err != nil {
- panic(err)
- }
-
- val, err := rdb.Get(ctx, "key").Result()
- if err != nil {
- panic(err)
- }
- fmt.Println("key", val)
-
- val2, err := rdb.Get(ctx, "key2").Result()
- if err == redis.Nil {
- fmt.Println("key2 does not exist")
- } else if err != nil {
- panic(err)
- } else {
- fmt.Println("key2", val2)
- }
- // Output: key value
- // key2 does not exist
-}
-```
-
-## Look and feel
-
-Some corner cases:
-
-```go
-// SET key value EX 10 NX
-set, err := rdb.SetNX(ctx, "key", "value", 10*time.Second).Result()
-
-// SET key value keepttl NX
-set, err := rdb.SetNX(ctx, "key", "value", redis.KeepTTL).Result()
-
-// SORT list LIMIT 0 2 ASC
-vals, err := rdb.Sort(ctx, "list", &redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
-
-// ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
-vals, err := rdb.ZRangeByScoreWithScores(ctx, "zset", &redis.ZRangeBy{
- Min: "-inf",
- Max: "+inf",
- Offset: 0,
- Count: 2,
-}).Result()
-
-// ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
-vals, err := rdb.ZInterStore(ctx, "out", &redis.ZStore{
- Keys: []string{"zset1", "zset2"},
- Weights: []int64{2, 3}
-}).Result()
-
-// EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
-vals, err := rdb.Eval(ctx, "return {KEYS[1],ARGV[1]}", []string{"key"}, "hello").Result()
-
-// custom command
-res, err := rdb.Do(ctx, "set", "key", "value").Result()
-```
-
-## Run the test
-
-go-redis will start a redis-server and run the test cases.
-
-The paths of redis-server bin file and redis config file are defined in `main_test.go`:
-
-```
-var (
- redisServerBin, _ = filepath.Abs(filepath.Join("testdata", "redis", "src", "redis-server"))
- redisServerConf, _ = filepath.Abs(filepath.Join("testdata", "redis", "redis.conf"))
-)
-```
-
-For local testing, you can change the variables to refer to your local files, or create a soft link
-to the corresponding folder for redis-server and copy the config file to `testdata/redis/`:
-
-```
-ln -s /usr/bin/redis-server ./go-redis/testdata/redis/src
-cp ./go-redis/testdata/redis.conf ./go-redis/testdata/redis/
-```
-
-Lastly, run:
-
-```
-go test
-```

-// Most Option fields can be set using query parameters, with the following restrictions:
-// - field names are mapped using snake-case conversion: to set MaxRetries, use max_retries
-// - only scalar type fields are supported (bool, int, time.Duration)
-// - for time.Duration fields, values must be a valid input for time.ParseDuration();
-// additionally a plain integer as value (i.e. without unit) is intepreted as seconds
-// - to disable a duration field, use value less than or equal to 0; to use the default
-// value, leave the value blank or remove the parameter
-// - only the last value is interpreted if a parameter is given multiple times
-// - fields "network", "addr", "username" and "password" can only be set using other
-// URL attributes (scheme, host, userinfo, resp.), query paremeters using these
-// names will be treated as unknown parameters
-// - unknown parameter names will result in an error

-// Package websocket implements the WebSocket protocol defined in RFC 6455.
-//
-// Overview
-//
-// The Conn type represents a WebSocket connection. A server application calls
-// the Upgrader.Upgrade method from an HTTP request handler to get a *Conn:
-//
-// var upgrader = websocket.Upgrader{
-// ReadBufferSize: 1024,
-// WriteBufferSize: 1024,
-// }
-//
-// func handler(w http.ResponseWriter, r *http.Request) {
-// conn, err := upgrader.Upgrade(w, r, nil)
-// if err != nil {
-// log.Println(err)
-// return
-// }
-// ... Use conn to send and receive messages.
-// }
-//
-// Call the connection's WriteMessage and ReadMessage methods to send and
-// receive messages as a slice of bytes. This snippet of code shows how to echo
-// messages using these methods:
-//
-// for {
-// messageType, p, err := conn.ReadMessage()
-// if err != nil {
-// log.Println(err)
-// return
-// }
-// if err := conn.WriteMessage(messageType, p); err != nil {
-// log.Println(err)
-// return
-// }
-// }
-//
-// In above snippet of code, p is a []byte and messageType is an int with value
-// websocket.BinaryMessage or websocket.TextMessage.
-//
-// An application can also send and receive messages using the io.WriteCloser
-// and io.Reader interfaces. To send a message, call the connection NextWriter
-// method to get an io.WriteCloser, write the message to the writer and close
-// the writer when done. To receive a message, call the connection NextReader
-// method to get an io.Reader and read until io.EOF is returned. This snippet
-// shows how to echo messages using the NextWriter and NextReader methods:
-//
-// for {
-// messageType, r, err := conn.NextReader()
-// if err != nil {
-// return
-// }
-// w, err := conn.NextWriter(messageType)
-// if err != nil {
-// return err
-// }
-// if _, err := io.Copy(w, r); err != nil {
-// return err
-// }
-// if err := w.Close(); err != nil {
-// return err
-// }
-// }
-//
-// Data Messages
-//
-// The WebSocket protocol distinguishes between text and binary data messages.
-// Text messages are interpreted as UTF-8 encoded text. The interpretation of
-// binary messages is left to the application.
-//
-// This package uses the TextMessage and BinaryMessage integer constants to
-// identify the two data message types. The ReadMessage and NextReader methods
-// return the type of the received message. The messageType argument to the
-// WriteMessage and NextWriter methods specifies the type of a sent message.
-//
-// It is the application's responsibility to ensure that text messages are
-// valid UTF-8 encoded text.
-//
-// Control Messages
-//
-// The WebSocket protocol defines three types of control messages: close, ping
-// and pong. Call the connection WriteControl, WriteMessage or NextWriter
-// methods to send a control message to the peer.
-//
-// Connections handle received close messages by calling the handler function
-// set with the SetCloseHandler method and by returning a *CloseError from the
-// NextReader, ReadMessage or the message Read method. The default close
-// handler sends a close message to the peer.
-//
-// Connections handle received ping messages by calling the handler function
-// set with the SetPingHandler method. The default ping handler sends a pong
-// message to the peer.
-//
-// Connections handle received pong messages by calling the handler function
-// set with the SetPongHandler method. The default pong handler does nothing.
-// If an application sends ping messages, then the application should set a
-// pong handler to receive the corresponding pong.
-//
-// The control message handler functions are called from the NextReader,
-// ReadMessage and message reader Read methods. The default close and ping
-// handlers can block these methods for a short time when the handler writes to
-// the connection.
-//
-// The application must read the connection to process close, ping and pong
-// messages sent from the peer. If the application is not otherwise interested
-// in messages from the peer, then the application should start a goroutine to
-// read and discard messages from the peer. A simple example is:
-//
-// func readLoop(c *websocket.Conn) {
-// for {
-// if _, _, err := c.NextReader(); err != nil {
-// c.Close()
-// break
-// }
-// }
-// }
-//
-// Concurrency
-//
-// Connections support one concurrent reader and one concurrent writer.
-//
-// Applications are responsible for ensuring that no more than one goroutine
-// calls the write methods (NextWriter, SetWriteDeadline, WriteMessage,
-// WriteJSON, EnableWriteCompression, SetCompressionLevel) concurrently and
-// that no more than one goroutine calls the read methods (NextReader,
-// SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler, SetPingHandler)
-// concurrently.
-//
-// The Close and WriteControl methods can be called concurrently with all other
-// methods.
-//
-// Origin Considerations
-//
-// Web browsers allow Javascript applications to open a WebSocket connection to
-// any host. It's up to the server to enforce an origin policy using the Origin
-// request header sent by the browser.
-//
-// The Upgrader calls the function specified in the CheckOrigin field to check
-// the origin. If the CheckOrigin function returns false, then the Upgrade
-// method fails the WebSocket handshake with HTTP status 403.
-//
-// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail
-// the handshake if the Origin request header is present and the Origin host is
-// not equal to the Host request header.
-//
-// The deprecated package-level Upgrade function does not perform origin
-// checking. The application is responsible for checking the Origin header
-// before calling the Upgrade function.
-//
-// Buffers
-//
-// Connections buffer network input and output to reduce the number
-// of system calls when reading or writing messages.
-//
-// Write buffers are also used for constructing WebSocket frames. See RFC 6455,
-// Section 5 for a discussion of message framing. A WebSocket frame header is
-// written to the network each time a write buffer is flushed to the network.
-// Decreasing the size of the write buffer can increase the amount of framing
-// overhead on the connection.
-//
-// The buffer sizes in bytes are specified by the ReadBufferSize and
-// WriteBufferSize fields in the Dialer and Upgrader. The Dialer uses a default
-// size of 4096 when a buffer size field is set to zero. The Upgrader reuses
-// buffers created by the HTTP server when a buffer size field is set to zero.
-// The HTTP server buffers have a size of 4096 at the time of this writing.
-//
-// The buffer sizes do not limit the size of a message that can be read or
-// written by a connection.
-//
-// Buffers are held for the lifetime of the connection by default. If the
-// Dialer or Upgrader WriteBufferPool field is set, then a connection holds the
-// write buffer only when writing a message.
-//
-// Applications should tune the buffer sizes to balance memory use and
-// performance. Increasing the buffer size uses more memory, but can reduce the
-// number of system calls to read or write the network. In the case of writing,
-// increasing the buffer size can reduce the number of frame headers written to
-// the network.
-//
-// Some guidelines for setting buffer parameters are:
-//
-// Limit the buffer sizes to the maximum expected message size. Buffers larger
-// than the largest message do not provide any benefit.
-//
-// Depending on the distribution of message sizes, setting the buffer size to
-// a value less than the maximum expected message size can greatly reduce memory
-// use with a small impact on performance. Here's an example: If 99% of the
-// messages are smaller than 256 bytes and the maximum message size is 512
-// bytes, then a buffer size of 256 bytes will result in 1.01 more system calls
-// than a buffer size of 512 bytes. The memory savings is 50%.
-//
-// A write buffer pool is useful when the application has a modest number
-// writes over a large number of connections. when buffers are pooled, a larger
-// buffer size has a reduced impact on total memory use and has the benefit of
-// reducing system calls and frame overhead.
-//
-// Compression EXPERIMENTAL
-//
-// Per message compression extensions (RFC 7692) are experimentally supported
-// by this package in a limited capacity. Setting the EnableCompression option
-// to true in Dialer or Upgrader will attempt to negotiate per message deflate
-// support.
-//
-// var upgrader = websocket.Upgrader{
-// EnableCompression: true,
-// }
-//
-// If compression was successfully negotiated with the connection's peer, any
-// message received in compressed form will be automatically decompressed.
-// All Read methods will return uncompressed bytes.
-//
-// Per message compression of messages written to a connection can be enabled
-// or disabled by calling the corresponding Conn method:
-//
-// conn.EnableWriteCompression(false)
-//
-// Currently this package does not support compression with "context takeover".
-// This means that messages must be compressed and decompressed in isolation,
-// without retaining sliding window or dictionary state across messages. For
-// more details refer to RFC 7692.
-//

-# Copier
-
- I am a copier, I copy everything from one to another
-
-[](https://github.com/jinzhu/copier/actions)
-
-## Features
-
-* Copy from field to field with same name
-* Copy from method to field with same name
-* Copy from field to method with same name
-* Copy from slice to slice
-* Copy from struct to slice
-* Copy from map to map
-* Enforce copying a field with a tag
-* Ignore a field with a tag
-* Deep Copy
-
-## Usage
-
-```go
-package main
-
-import (
- "fmt"
- "github.com/jinzhu/copier"
-)
-
-type User struct {
- Name string
- Role string
- Age int32
- EmployeCode int64 `copier:"EmployeNum"` // specify field name
-
- // Explicitly ignored in the destination struct.
- Salary int
-}
-
-func (user *User) DoubleAge() int32 {
- return 2 * user.Age
-}
-
-// Tags in the destination Struct provide instructions to copier.Copy to ignore
-// or enforce copying and to panic or return an error if a field was not copied.
-type Employee struct {
- // Tell copier.Copy to panic if this field is not copied.
- Name string `copier:"must"`
-
- // Tell copier.Copy to return an error if this field is not copied.
- Age int32 `copier:"must,nopanic"`
-
- // Tell copier.Copy to explicitly ignore copying this field.
- Salary int `copier:"-"`
-
- DoubleAge int32
- EmployeId int64 `copier:"EmployeNum"` // specify field name
- SuperRole string
-}
-
-func (employee *Employee) Role(role string) {
- employee.SuperRole = "Super " + role
-}
-
-func main() {
- var (
- user = User{Name: "Jinzhu", Age: 18, Role: "Admin", Salary: 200000}
- users = []User{{Name: "Jinzhu", Age: 18, Role: "Admin", Salary: 100000}, {Name: "jinzhu 2", Age: 30, Role: "Dev", Salary: 60000}}
- employee = Employee{Salary: 150000}
- employees = []Employee{}
- )
-
- copier.Copy(&employee, &user)
-
- fmt.Printf("%#v \n", employee)
- // Employee{
- // Name: "Jinzhu", // Copy from field
- // Age: 18, // Copy from field
- // Salary:150000, // Copying explicitly ignored
- // DoubleAge: 36, // Copy from method
- // EmployeeId: 0, // Ignored
- // SuperRole: "Super Admin", // Copy to method
- // }
-
- // Copy struct to slice
- copier.Copy(&employees, &user)
-
- fmt.Printf("%#v \n", employees)
- // []Employee{
- // {Name: "Jinzhu", Age: 18, Salary:0, DoubleAge: 36, EmployeId: 0, SuperRole: "Super Admin"}
- // }
-
- // Copy slice to slice
- employees = []Employee{}
- copier.Copy(&employees, &users)
-
- fmt.Printf("%#v \n", employees)
- // []Employee{
- // {Name: "Jinzhu", Age: 18, Salary:0, DoubleAge: 36, EmployeId: 0, SuperRole: "Super Admin"},
- // {Name: "jinzhu 2", Age: 30, Salary:0, DoubleAge: 60, EmployeId: 0, SuperRole: "Super Dev"},
- // }
-
- // Copy map to map
- map1 := map[int]int{3: 6, 4: 8}
- map2 := map[int32]int8{}
- copier.Copy(&map2, map1)
-
- fmt.Printf("%#v \n", map2)
- // map[int32]int8{3:6, 4:8}
-}
-```
-
-### Copy with Option
-
-```go
-copier.CopyWithOption(&to, &from, copier.Option{IgnoreEmpty: true, DeepCopy: true})
-```

-Colorable writer for windows.
-
-For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
-This package is possible to handle escape sequence for ansi color on windows.
-
-## Too Bad!
-
-
-
-
-## So Good!
-
-
-
-## Usage
-
-```go
-logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
-logrus.SetOutput(colorable.NewColorableStdout())
-
-logrus.Info("succeeded")
-logrus.Warn("not correct")
-logrus.Error("something error")
-logrus.Fatal("panic")
-```
-
-You can compile above code on non-windows OSs.
-
-## Installation
-
-```
-$ go get github.com/mattn/go-colorable

-Package errors provides simple error handling primitives.
-
-`go get github.com/pkg/errors`
-
-The traditional error handling idiom in Go is roughly akin to
-```go
-if err != nil {
- return err
-}
-```
-which applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error.
-
-## Adding context to an error
-
-The errors.Wrap function returns a new error that adds context to the original error. For example
-```go
-_, err := ioutil.ReadAll(r)
-if err != nil {
- return errors.Wrap(err, "read failed")
-}
-```
-## Retrieving the cause of an error
-
-Using `errors.Wrap` constructs a stack of errors, adding context to the preceding error. Depending on the nature of the error it may be necessary to reverse the operation of errors.Wrap to retrieve the original error for inspection. Any error value which implements this interface can be inspected by `errors.Cause`.
-```go
-type causer interface {
- Cause() error
-}
-```
-`errors.Cause` will recursively retrieve the topmost error which does not implement `causer`, which is assumed to be the original cause. For example:
-```go
-switch err := errors.Cause(err).(type) {
-case *MyError:
- // handle specifically
-default:
- // unknown error
-}
-```
-
-[Read the package documentation for more information](https://godoc.org/github.com/pkg/errors).
-
-## Roadmap
-
-With the upcoming [Go2 error proposals](https://go.googlesource.com/proposal/+/master/design/go2draft.md) this package is moving into maintenance mode. The roadmap for a 1.0 release is as follows:
-
-- 0.9. Remove pre Go 1.9 and Go 1.10 support, address outstanding pull requests (if possible)
-- 1.0. Final release.
-
-## Contributing
-
-Because of the Go2 errors changes, this package is not accepting proposals for new functionality. With that said, we welcome pull requests, bug fixes and issue reports.
-
-Before sending a PR, please discuss your change by raising an issue.

-// New, Errorf, Wrap, and Wrapf record a stack trace at the point they are
-// invoked. This information can be retrieved with the following interface:
-//
-// type stackTracer interface {
-// StackTrace() errors.StackTrace
-// }
-//
-// The returned errors.StackTrace type is defined as
-//
-// type StackTrace []Frame
-//
-// The Frame type represents a call site in the stack trace. Frame supports
-// the fmt.Formatter interface that can be used for printing information about
-// the stack trace of this error. For example:
-//
-// if err, ok := err.(stackTracer); ok {
-// for _, f := range err.StackTrace() {
-// fmt.Printf("%+s:%d\n", f, f)
-// }
-// }
-//
-// Although the stackTracer interface is not exported by this package, it is
-// considered a part of its stable public interface.
-//
-// See the documentation for Frame.Format for more details.

-// SequenceMatcher compares sequence of strings. The basic
-// algorithm predates, and is a little fancier than, an algorithm
-// published in the late 1980's by Ratcliff and Obershelp under the
-// hyperbolic name "gestalt pattern matching". The basic idea is to find
-// the longest contiguous matching subsequence that contains no "junk"
-// elements (R-O doesn't address junk). The same idea is then applied
-// recursively to the pieces of the sequences to the left and to the right
-// of the matching subsequence. This does not yield minimal edit
-// sequences, but does tend to yield matches that "look right" to people.
-//
-// SequenceMatcher tries to compute a "human-friendly diff" between two
-// sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the
-// longest *contiguous* & junk-free matching subsequence. That's what
-// catches peoples' eyes. The Windows(tm) windiff has another interesting
-// notion, pairing up elements that appear uniquely in each sequence.
-// That, and the method here, appear to yield more intuitive difference
-// reports than does diff. This method appears to be the least vulnerable
-// to synching up on blocks of "junk lines", though (like blank lines in
-// ordinary text files, or maybe "" lines in HTML files). That may be
-// because this is the only method of the 3 that has a *concept* of
-// "junk" .
-//
-// Timing: Basic R-O is cubic time worst case and quadratic time expected
-// case. SequenceMatcher is quadratic time for the worst case and has
-// expected-case behavior dependent in a complicated way on how many
-// elements the sequences have in common; best case time is linear.

-# Globally Unique ID Generator
-
-[](https://godoc.org/github.com/rs/xid) [](https://raw.githubusercontent.com/rs/xid/master/LICENSE) [](https://travis-ci.org/rs/xid) [](http://gocover.io/github.com/rs/xid)
-
-Package xid is a globally unique id generator library, ready to safely be used directly in your server code.
-
-Xid uses the Mongo Object ID algorithm to generate globally unique ids with a different serialization (base64) to make it shorter when transported as a string:
-https://docs.mongodb.org/manual/reference/object-id/
-
-- 4-byte value representing the seconds since the Unix epoch,
-- 3-byte machine identifier,
-- 2-byte process id, and
-- 3-byte counter, starting with a random value.
-
-The binary representation of the id is compatible with Mongo 12 bytes Object IDs.
-The string representation is using base32 hex (w/o padding) for better space efficiency
-when stored in that form (20 bytes). The hex variant of base32 is used to retain the
-sortable property of the id.
-
-Xid doesn't use base64 because case sensitivity and the 2 non alphanum chars may be an
-issue when transported as a string between various systems. Base36 wasn't retained either
-because 1/ it's not standard 2/ the resulting size is not predictable (not bit aligned)
-and 3/ it would not remain sortable. To validate a base32 `xid`, expect a 20 chars long,
-all lowercase sequence of `a` to `v` letters and `0` to `9` numbers (`[0-9a-v]{20}`).
-
-UUIDs are 16 bytes (128 bits) and 36 chars as string representation. Twitter Snowflake
-ids are 8 bytes (64 bits) but require machine/data-center configuration and/or central
-generator servers. xid stands in between with 12 bytes (96 bits) and a more compact
-URL-safe string representation (20 chars). No configuration or central generator server
-is required so it can be used directly in server's code.
-
-| Name | Binary Size | String Size | Features
-|-------------|-------------|----------------|----------------
-| [UUID] | 16 bytes | 36 chars | configuration free, not sortable
-| [shortuuid] | 16 bytes | 22 chars | configuration free, not sortable
-| [Snowflake] | 8 bytes | up to 20 chars | needs machine/DC configuration, needs central server, sortable
-| [MongoID] | 12 bytes | 24 chars | configuration free, sortable
-| xid | 12 bytes | 20 chars | configuration free, sortable
-
-[UUID]: https://en.wikipedia.org/wiki/Universally_unique_identifier
-[shortuuid]: https://github.com/stochastic-technologies/shortuuid
-[Snowflake]: https://blog.twitter.com/2010/announcing-snowflake
-[MongoID]: https://docs.mongodb.org/manual/reference/object-id/
-
-Features:
-
-- Size: 12 bytes (96 bits), smaller than UUID, larger than snowflake
-- Base32 hex encoded by default (20 chars when transported as printable string, still sortable)
-- Non configured, you don't need set a unique machine and/or data center id
-- K-ordered
-- Embedded time with 1 second precision
-- Unicity guaranteed for 16,777,216 (24 bits) unique ids per second and per host/process
-- Lock-free (i.e.: unlike UUIDv1 and v2)
-
-Best used with [zerolog](https://github.com/rs/zerolog)'s
-[RequestIDHandler](https://godoc.org/github.com/rs/zerolog/hlog#RequestIDHandler).
-
-Notes:
-
-- Xid is dependent on the system time, a monotonic counter and so is not cryptographically secure. If unpredictability of IDs is important, you should not use Xids. It is worth noting that most other UUID-like implementations are also not cryptographically secure. You should use libraries that rely on cryptographically secure sources (like /dev/urandom on unix, crypto/rand in golang), if you want a truly random ID generator.

-// Package xid is a globally unique id generator suited for web scale
-//
-// Xid is using Mongo Object ID algorithm to generate globally unique ids:
-// https://docs.mongodb.org/manual/reference/object-id/
-//
-// - 4-byte value representing the seconds since the Unix epoch,
-// - 3-byte machine identifier,
-// - 2-byte process id, and
-// - 3-byte counter, starting with a random value.
-//
-// The binary representation of the id is compatible with Mongo 12 bytes Object IDs.
-// The string representation is using base32 hex (w/o padding) for better space efficiency
-// when stored in that form (20 bytes). The hex variant of base32 is used to retain the
-// sortable property of the id.
-//
-// Xid doesn't use base64 because case sensitivity and the 2 non alphanum chars may be an
-// issue when transported as a string between various systems. Base36 wasn't retained either
-// because 1/ it's not standard 2/ the resulting size is not predictable (not bit aligned)
-// and 3/ it would not remain sortable. To validate a base32 `xid`, expect a 20 chars long,
-// all lowercase sequence of `a` to `v` letters and `0` to `9` numbers (`[0-9a-v]{20}`).
-//
-// UUID is 16 bytes (128 bits), snowflake is 8 bytes (64 bits), xid stands in between
-// with 12 bytes with a more compact string representation ready for the web and no
-// required configuration or central generation server.
-//
-// Features:
-//
-// - Size: 12 bytes (96 bits), smaller than UUID, larger than snowflake
-// - Base32 hex encoded by default (16 bytes storage when transported as printable string)
-// - Non configured, you don't need set a unique machine and/or data center id
-// - K-ordered
-// - Embedded time with 1 second precision
-// - Unicity guaranteed for 16,777,216 (24 bits) unique ids per second and per host/process
-//
-// Best used with xlog's RequestIDHandler (https://godoc.org/github.com/rs/xlog#RequestIDHandler).

-[](https://godoc.org/github.com/rs/zerolog) [](https://raw.githubusercontent.com/rs/zerolog/master/LICENSE) [](https://travis-ci.org/rs/zerolog) [](http://gocover.io/github.com/rs/zerolog)
-
-The zerolog package provides a fast and simple logger dedicated to JSON output.
-
-Zerolog's API is designed to provide both a great developer experience and stunning [performance](#benchmarks). Its unique chaining API allows zerolog to write JSON (or CBOR) log events by avoiding allocations and reflection.
-
-Uber's [zap](https://godoc.org/go.uber.org/zap) library pioneered this approach. Zerolog is taking this concept to the next level with a simpler to use API and even better performance.
-
-To keep the code base and the API simple, zerolog focuses on efficient structured logging only. Pretty logging on the console is made possible using the provided (but inefficient) [`zerolog.ConsoleWriter`](#pretty-logging).

-## Installation
-
-```bash
-go get -u github.com/rs/zerolog/log
-```
-
-## Getting Started
-
-### Simple Logging Example
-
-For simple logging, import the global logger package **github.com/rs/zerolog/log**
-
-```go
-package main
-
-import (
- "github.com/rs/zerolog"
- "github.com/rs/zerolog/log"
-)
-
-func main() {
- // UNIX Time is faster and smaller than most timestamps
- zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
-
- log.Print("hello world")
-}
-
-// Output: {"time":1516134303,"level":"debug","message":"hello world"}
-```
-> Note: By default log writes to `os.Stderr`
-> Note: The default log level for `log.Print` is *debug*
-
-### Contextual Logging
-
-**zerolog** allows data to be added to log messages in the form of key:value pairs. The data added to the message adds "context" about the log event that can be critical for debugging as well as myriad other purposes. An example of this is below:
-
-```go
-package main
-
-import (
- "github.com/rs/zerolog"
- "github.com/rs/zerolog/log"
-)
-
-func main() {
- zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
-
- log.Debug().
- Str("Scale", "833 cents").
- Float64("Interval", 833.09).
- Msg("Fibonacci is everywhere")
-
- log.Debug().
- Str("Name", "Tom").
- Send()
-}
-
-// Output: {"level":"debug","Scale":"833 cents","Interval":833.09,"time":1562212768,"message":"Fibonacci is everywhere"}
-// Output: {"level":"debug","Name":"Tom","time":1562212768}
-```
-
-> You'll note in the above example that when adding contextual fields, the fields are strongly typed. You can find the full list of supported fields [here](#standard-types)
-
-### Leveled Logging
-
-#### Simple Leveled Logging Example
-
-```go
-package main
-
-import (
- "github.com/rs/zerolog"
- "github.com/rs/zerolog/log"
-)
-
-func main() {
- zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
-
- log.Info().Msg("hello world")
-}
-
-// Output: {"time":1516134303,"level":"info","message":"hello world"}
-```
-
-> It is very important to note that when using the **zerolog** chaining API, as shown above (`log.Info().Msg("hello world"`), the chain must have either the `Msg` or `Msgf` method call. If you forget to add either of these, the log will not occur and there is no compile time error to alert you of this.
-
-**zerolog** allows for logging at the following levels (from highest to lowest):
-
-* panic (`zerolog.PanicLevel`, 5)
-* fatal (`zerolog.FatalLevel`, 4)
-* error (`zerolog.ErrorLevel`, 3)
-* warn (`zerolog.WarnLevel`, 2)
-* info (`zerolog.InfoLevel`, 1)
-* debug (`zerolog.DebugLevel`, 0)
-* trace (`zerolog.TraceLevel`, -1)
-
-You can set the Global logging level to any of these options using the `SetGlobalLevel` function in the zerolog package, passing in one of the given constants above, e.g. `zerolog.InfoLevel` would be the "info" level. Whichever level is chosen, all logs with a level greater than or equal to that level will be written. To turn off logging entirely, pass the `zerolog.Disabled` constant.
-
-#### Setting Global Log Level
-
-This example uses command-line flags to demonstrate various outputs depending on the chosen log level.
-
-```go
-package main
-
-import (
- "flag"
-
- "github.com/rs/zerolog"
- "github.com/rs/zerolog/log"
-)
-
-func main() {
- zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
- debug := flag.Bool("debug", false, "sets log level to debug")
-
- flag.Parse()
-
- // Default level for this example is info, unless debug flag is present
- zerolog.SetGlobalLevel(zerolog.InfoLevel)
- if *debug {
- zerolog.SetGlobalLevel(zerolog.DebugLevel)
- }
-
- log.Debug().Msg("This message appears only when log level set to Debug")
- log.Info().Msg("This message appears when log level set to Debug or Info")
-
- if e := log.Debug(); e.Enabled() {
- // Compute log output only if enabled.
- value := "bar"
- e.Str("foo", value).Msg("some debug message")
- }
-}
-```
-
-Info Output (no flag)
-
-```bash
-$ ./logLevelExample
-{"time":1516387492,"level":"info","message":"This message appears when log level set to Debug or Info"}
-```
-
-Debug Output (debug flag set)
-
-```bash
-$ ./logLevelExample -debug
-{"time":1516387573,"level":"debug","message":"This message appears only when log level set to Debug"}
-{"time":1516387573,"level":"info","message":"This message appears when log level set to Debug or Info"}
-{"time":1516387573,"level":"debug","foo":"bar","message":"some debug message"}
-```
-
-#### Logging without Level or Message
-
-You may choose to log without a specific level by using the `Log` method. You may also write without a message by setting an empty string in the `msg string` parameter of the `Msg` method. Both are demonstrated in the example below.
-
-```go
-package main
-
-import (
- "github.com/rs/zerolog"
- "github.com/rs/zerolog/log"
-)
-
-func main() {
- zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
-
- log.Log().
- Str("foo", "bar").
- Msg("")
-}
-
-// Output: {"time":1494567715,"foo":"bar"}
-```
-
-### Error Logging
-
-You can log errors using the `Err` method
-
-```go
-package main
-
-import (
- "errors"
-
- "github.com/rs/zerolog"
- "github.com/rs/zerolog/log"
-)
-
-func main() {
- zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
-
- err := errors.New("seems we have an error here")
- log.Error().Err(err).Msg("")
-}
-
-// Output: {"level":"error","error":"seems we have an error here","time":1609085256}
-```
-
-> The default field name for errors is `error`, you can change this by setting `zerolog.ErrorFieldName` to meet your needs.
-
-#### Error Logging with Stacktrace
-
-Using `github.com/pkg/errors`, you can add a formatted stacktrace to your errors.
-
-```go
-package main
-
-import (
- "github.com/pkg/errors"
- "github.com/rs/zerolog/pkgerrors"
-
- "github.com/rs/zerolog"
- "github.com/rs/zerolog/log"
-)
-
-func main() {
- zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
- zerolog.ErrorStackMarshaler = pkgerrors.MarshalStack
-
- err := outer()
- log.Error().Stack().Err(err).Msg("")
-}
-
-func inner() error {
- return errors.New("seems we have an error here")
-}
-
-func middle() error {
- err := inner()
- if err != nil {
- return err
- }
- return nil
-}
-
-func outer() error {
- err := middle()
- if err != nil {
- return err
- }
- return nil
-}
-
-// Output: {"level":"error","stack":[{"func":"inner","line":"20","source":"errors.go"},{"func":"middle","line":"24","source":"errors.go"},{"func":"outer","line":"32","source":"errors.go"},{"func":"main","line":"15","source":"errors.go"},{"func":"main","line":"204","source":"proc.go"},{"func":"goexit","line":"1374","source":"asm_amd64.s"}],"error":"seems we have an error here","time":1609086683}
-```
-
-> zerolog.ErrorStackMarshaler must be set in order for the stack to output anything.
-
-#### Logging Fatal Messages
-
-```go
-package main
-
-import (
- "errors"
-
- "github.com/rs/zerolog"
- "github.com/rs/zerolog/log"
-)
-
-func main() {
- err := errors.New("A repo man spends his life getting into tense situations")
- service := "myservice"
-
- zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
-
- log.Fatal().
- Err(err).
- Str("service", service).
- Msgf("Cannot start %s", service)
-}
-
-// Output: {"time":1516133263,"level":"fatal","error":"A repo man spends his life getting into tense situations","service":"myservice","message":"Cannot start myservice"}
-// exit status 1
-```
-
-> NOTE: Using `Msgf` generates one allocation even when the logger is disabled.
-
-
-### Create logger instance to manage different outputs
-
-```go
-logger := zerolog.New(os.Stderr).With().Timestamp().Logger()
-
-logger.Info().Str("foo", "bar").Msg("hello world")
-
-// Output: {"level":"info","time":1494567715,"message":"hello world","foo":"bar"}
-```
-
-### Sub-loggers let you chain loggers with additional context
-
-```go
-sublogger := log.With().
- Str("component", "foo").
- Logger()
-sublogger.Info().Msg("hello world")
-
-// Output: {"level":"info","time":1494567715,"message":"hello world","component":"foo"}
-```
-
-### Pretty logging
-
-To log a human-friendly, colorized output, use `zerolog.ConsoleWriter`:
-
-```go
-log.Logger = log.Output(zerolog.ConsoleWriter{Out: os.Stderr})
-
-log.Info().Str("foo", "bar").Msg("Hello world")
-
-// Output: 3:04PM INF Hello World foo=bar
-```
-
-To customize the configuration and formatting:
-
-```go
-output := zerolog.ConsoleWriter{Out: os.Stdout, TimeFormat: time.RFC3339}
-output.FormatLevel = func(i interface{}) string {
- return strings.ToUpper(fmt.Sprintf("| %-6s|", i))
-}
-output.FormatMessage = func(i interface{}) string {
- return fmt.Sprintf("***%s****", i)
-}
-output.FormatFieldName = func(i interface{}) string {
- return fmt.Sprintf("%s:", i)
-}
-output.FormatFieldValue = func(i interface{}) string {
- return strings.ToUpper(fmt.Sprintf("%s", i))
-}
-
-log := zerolog.New(output).With().Timestamp().Logger()
-
-log.Info().Str("foo", "bar").Msg("Hello World")
-
-// Output: 2006-01-02T15:04:05Z07:00 | INFO | ***Hello World**** foo:BAR
-```
-
-### Sub dictionary
-
-```go
-log.Info().
- Str("foo", "bar").
- Dict("dict", zerolog.Dict().
- Str("bar", "baz").
- Int("n", 1),
- ).Msg("hello world")
-
-// Output: {"level":"info","time":1494567715,"foo":"bar","dict":{"bar":"baz","n":1},"message":"hello world"}
-```
-
-### Customize automatic field names
-
-```go
-zerolog.TimestampFieldName = "t"
-zerolog.LevelFieldName = "l"
-zerolog.MessageFieldName = "m"
-
-log.Info().Msg("hello world")
-
-// Output: {"l":"info","t":1494567715,"m":"hello world"}
-```
-
-### Add contextual fields to the global logger
-
-```go
-log.Logger = log.With().Str("foo", "bar").Logger()
-```
-
-### Add file and line number to log
-
-Equivalent of `Llongfile`:
-
-```go
-log.Logger = log.With().Caller().Logger()
-log.Info().Msg("hello world")
-
-// Output: {"level": "info", "message": "hello world", "caller": "/go/src/your_project/some_file:21"}
-```
-
-Equivalent of `Lshortfile`:
-
-```go
-zerolog.CallerMarshalFunc = func(file string, line int) string {
- short := file
- for i := len(file) - 1; i > 0; i-- {
- if file[i] == '/' {
- short = file[i+1:]
- break
- }
- }
- file = short
- return file + ":" + strconv.Itoa(line)
-}
-log.Logger = log.With().Caller().Logger()
-log.Info().Msg("hello world")
-
-// Output: {"level": "info", "message": "hello world", "caller": "some_file:21"}
-```
-
-### Thread-safe, lock-free, non-blocking writer
-
-If your writer might be slow or not thread-safe and you need your log producers to never get slowed down by a slow writer, you can use a `diode.Writer` as follows:
-
-```go
-wr := diode.NewWriter(os.Stdout, 1000, 10*time.Millisecond, func(missed int) {
- fmt.Printf("Logger Dropped %d messages", missed)
- })
-log := zerolog.New(wr)
-log.Print("test")
-```
-
-You will need to install `code.cloudfoundry.org/go-diodes` to use this feature.
-
-### Log Sampling
-
-```go
-sampled := log.Sample(&zerolog.BasicSampler{N: 10})
-sampled.Info().Msg("will be logged every 10 messages")
-
-// Output: {"time":1494567715,"level":"info","message":"will be logged every 10 messages"}
-```
-
-More advanced sampling:
-
-```go
-// Will let 5 debug messages per period of 1 second.
-// Over 5 debug message, 1 every 100 debug messages are logged.
-// Other levels are not sampled.
-sampled := log.Sample(zerolog.LevelSampler{
- DebugSampler: &zerolog.BurstSampler{
- Burst: 5,
- Period: 1*time.Second,
- NextSampler: &zerolog.BasicSampler{N: 100},
- },
-})
-sampled.Debug().Msg("hello world")
-
-// Output: {"time":1494567715,"level":"debug","message":"hello world"}
-```
-
-### Hooks
-
-```go
-type SeverityHook struct{}
-
-func (h SeverityHook) Run(e *zerolog.Event, level zerolog.Level, msg string) {
- if level != zerolog.NoLevel {
- e.Str("severity", level.String())
- }
-}
-
-hooked := log.Hook(SeverityHook{})
-hooked.Warn().Msg("")
-
-// Output: {"level":"warn","severity":"warn"}
-```
-
-### Pass a sub-logger by context
-
-```go
-ctx := log.With().Str("component", "module").Logger().WithContext(ctx)
-
-log.Ctx(ctx).Info().Msg("hello world")
-
-// Output: {"component":"module","level":"info","message":"hello world"}
-```
-
-### Set as standard logger output
-
-```go
-log := zerolog.New(os.Stdout).With().
- Str("foo", "bar").
- Logger()
-
-stdlog.SetFlags(0)
-stdlog.SetOutput(log)
-
-stdlog.Print("hello world")
-
-// Output: {"foo":"bar","message":"hello world"}
-```
-
-### Integration with `net/http`
-
-The `github.com/rs/zerolog/hlog` package provides some helpers to integrate zerolog with `http.Handler`.
-
-In this example we use [alice](https://github.com/justinas/alice) to install logger for better readability.
-
-```go
-log := zerolog.New(os.Stdout).With().
- Timestamp().
- Str("role", "my-service").
- Str("host", host).
- Logger()
-
-c := alice.New()
-
-// Install the logger handler with default output on the console
-c = c.Append(hlog.NewHandler(log))
-
-// Install some provided extra handler to set some request's context fields.
-// Thanks to that handler, all our logs will come with some prepopulated fields.
-c = c.Append(hlog.AccessHandler(func(r *http.Request, status, size int, duration time.Duration) {
- hlog.FromRequest(r).Info().
- Str("method", r.Method).
- Stringer("url", r.URL).
- Int("status", status).
- Int("size", size).
- Dur("duration", duration).
- Msg("")
-}))
-c = c.Append(hlog.RemoteAddrHandler("ip"))
-c = c.Append(hlog.UserAgentHandler("user_agent"))
-c = c.Append(hlog.RefererHandler("referer"))
-c = c.Append(hlog.RequestIDHandler("req_id", "Request-Id"))
-
-// Here is your final handler
-h := c.Then(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
- // Get the logger from the request's context. You can safely assume it
- // will be always there: if the handler is removed, hlog.FromRequest
- // will return a no-op logger.
- hlog.FromRequest(r).Info().
- Str("user", "current user").
- Str("status", "ok").
- Msg("Something happened")
-
- // Output: {"level":"info","time":"2001-02-03T04:05:06Z","role":"my-service","host":"local-hostname","req_id":"b4g0l5t6tfid6dtrapu0","user":"current user","status":"ok","message":"Something happened"}
-}))
-http.Handle("/", h)
-
-if err := http.ListenAndServe(":8080", nil); err != nil {
- log.Fatal().Err(err).Msg("Startup failed")
-}
-```
-
-## Multiple Log Output
-`zerolog.MultiLevelWriter` may be used to send the log message to multiple outputs.
-In this example, we send the log message to both `os.Stdout` and the in-built ConsoleWriter.
-```go
-func main() {
- consoleWriter := zerolog.ConsoleWriter{Out: os.Stdout}
-
- multi := zerolog.MultiLevelWriter(consoleWriter, os.Stdout)
-
- logger := zerolog.New(multi).With().Timestamp().Logger()
-
- logger.Info().Msg("Hello World!")
-}
-
-// Output (Line 1: Console; Line 2: Stdout)
-// 12:36PM INF Hello World!
-// {"level":"info","time":"2019-11-07T12:36:38+03:00","message":"Hello World!"}
-```
-
-## Global Settings
-
-Some settings can be changed and will be applied to all loggers:
-
-* `log.Logger`: You can set this value to customize the global logger (the one used by package level methods).
-* `zerolog.SetGlobalLevel`: Can raise the minimum level of all loggers. Call this with `zerolog.Disabled` to disable logging altogether (quiet mode).
-* `zerolog.DisableSampling`: If argument is `true`, all sampled loggers will stop sampling and issue 100% of their log events.
-* `zerolog.TimestampFieldName`: Can be set to customize `Timestamp` field name.
-* `zerolog.LevelFieldName`: Can be set to customize level field name.
-* `zerolog.MessageFieldName`: Can be set to customize message field name.
-* `zerolog.ErrorFieldName`: Can be set to customize `Err` field name.
-* `zerolog.TimeFieldFormat`: Can be set to customize `Time` field value formatting. If set with `zerolog.TimeFormatUnix`, `zerolog.TimeFormatUnixMs` or `zerolog.TimeFormatUnixMicro`, times are formated as UNIX timestamp.
-* `zerolog.DurationFieldUnit`: Can be set to customize the unit for time.Duration type fields added by `Dur` (default: `time.Millisecond`).
-* `zerolog.DurationFieldInteger`: If set to `true`, `Dur` fields are formatted as integers instead of floats (default: `false`).
-* `zerolog.ErrorHandler`: Called whenever zerolog fails to write an event on its output. If not set, an error is printed on the stderr. This handler must be thread safe and non-blocking.
-
-## Field Types
-
-### Standard Types
-
-* `Str`
-* `Bool`
-* `Int`, `Int8`, `Int16`, `Int32`, `Int64`
-* `Uint`, `Uint8`, `Uint16`, `Uint32`, `Uint64`
-* `Float32`, `Float64`
-
-### Advanced Fields
-
-* `Err`: Takes an `error` and renders it as a string using the `zerolog.ErrorFieldName` field name.
-* `Func`: Run a `func` only if the level is enabled.
-* `Timestamp`: Inserts a timestamp field with `zerolog.TimestampFieldName` field name, formatted using `zerolog.TimeFieldFormat`.
-* `Time`: Adds a field with time formatted with `zerolog.TimeFieldFormat`.
-* `Dur`: Adds a field with `time.Duration`.
-* `Dict`: Adds a sub-key/value as a field of the event.
-* `RawJSON`: Adds a field with an already encoded JSON (`[]byte`)
-* `Hex`: Adds a field with value formatted as a hexadecimal string (`[]byte`)
-* `Interface`: Uses reflection to marshal the type.
-
-Most fields are also available in the slice format (`Strs` for `[]string`, `Errs` for `[]error` etc.)
-
-## Binary Encoding
-
-In addition to the default JSON encoding, `zerolog` can produce binary logs using [CBOR](https://cbor.io) encoding. The choice of encoding can be decided at compile time using the build tag `binary_log` as follows:
-
-```bash
-go build -tags binary_log .
-```
-
-To Decode binary encoded log files you can use any CBOR decoder. One has been tested to work
-with zerolog library is [CSD](https://github.com/toravir/csd/).

-## Caveats
-
-Note that zerolog does no de-duplication of fields. Using the same key multiple times creates multiple keys in final JSON:
-
-```go
-logger := zerolog.New(os.Stderr).With().Timestamp().Logger()
-logger.Info().
- Timestamp().
- Msg("dup")
-// Output: {"level":"info","time":1494567715,"time":1494567715,"message":"dup"}
-```
-
-In this case, many consumers will take the last value, but this is not guaranteed; check yours if in doubt.

-## Reference:
- CBOR Encoding is described in [RFC7049](https://tools.ietf.org/html/rfc7049)
-
-## Comparison of JSON vs CBOR
-
-Two main areas of reduction are:
-
-1. CPU usage to write a log msg
-2. Size (in bytes) of log messages.
-
-
-CPU Usage savings are below:
-```

-```
-
-Log message size savings is greatly dependent on the number and type of fields in the log message.
-Assuming this log message (with an Integer, timestamp and string, in addition to level).
-
-`{"level":"error","Fault":41650,"time":"2018-04-01T15:18:19-07:00","message":"Some Message"}`
-
-Two measurements were done for the log file sizes - one without any compression, second
-using [compress/zlib](https://golang.org/pkg/compress/zlib/).
-
-Results for 10,000 log messages:
-
-| Log Format | Plain File Size (in KB) | Compressed File Size (in KB) |
-| :--- | :---: | :---: |
-| JSON | 920 | 28 |
-| CBOR | 550 | 28 |
-
-The example used to calculate the above data is available in [Examples](examples).

-// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
-//
-// Example Usage
-//
-// The following is a complete example using assert in a standard test function:
-// import (
-// "testing"
-// "github.com/stretchr/testify/assert"
-// )
-//
-// func TestSomething(t *testing.T) {
-//
-// var a string = "Hello"
-// var b string = "Hello"
-//
-// assert.Equal(t, a, b, "The two words should be the same.")
-//
-// }
-//
-// if you assert many times, use the format below:
-//
-// import (
-// "testing"
-// "github.com/stretchr/testify/assert"
-// )
-//
-// func TestSomething(t *testing.T) {
-// assert := assert.New(t)
-//
-// var a string = "Hello"
-// var b string = "Hello"
-//
-// assert.Equal(a, b, "The two words should be the same.")
-// }
-//
-// Assertions
-//
-// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
-// All assertion functions take, as the first argument, the `*testing.T` object provided by the
-// testing framework. This allows the assertion funcs to write the failings and other details to
-// the correct place.
-//
-// Every assertion function also takes an optional string message as the final argument,
-// allowing custom error messages to be appended to the message the assertion method outputs.

-// Package require implements the same assertions as the `assert` package but

-// Example Usage
-//
-// The following is a complete example using require in a standard test function:
-// import (
-// "testing"
-// "github.com/stretchr/testify/require"
-// )
-//
-// func TestSomething(t *testing.T) {
-//
-// var a string = "Hello"
-// var b string = "Hello"
-//
-// require.Equal(t, a, b, "The two words should be the same.")
-//
-// }
-//
-// Assertions
-//
-// The `require` package have same global functions as in the `assert` package,
-// but instead of returning a boolean result they call `t.FailNow()`.
-//
-// Every assertion function also takes an optional string message as the final argument,
-// allowing custom error messages to be appended to the message the assertion method outputs.

-# BadgerHold
-
-[](https://travis-ci.org/timshannon/badgerhold) [](https://godoc.org/github.com/timshannon/badgerhold) [](https://coveralls.io/github/timshannon/badgerhold?branch=master) [](https://goreportcard.com/report/github.com/timshannon/badgerhold)
-
-BadgerHold is a simple querying and indexing layer on top of a [Badger](https://github.com/dgraph-io/badger) instance. The goal is to create a simple, higher level interface on top of Badger DB that simplifies dealing with Go Types and finding data, but exposes the underlying Badger DB for customizing as you wish. By default the encoding used is Gob, so feel free to use the GobEncoder/Decoder interface for faster serialization. Or, alternately, you can use any serialization you want by supplying encode / decode funcs to the `Options` struct on Open.
-
-One Go Type will be prefixed with it's type name, so you can store multiple types in a single Badger database with conflicts.
-
-This project is a rewrite of the [BoltHold](https://github.com/timshannon/bolthold) project on the Badger KV database instead of [Bolt](https://github.com/etcd-io/bbolt). For a performance comparison between bolt and badger, see https://blog.dgraph.io/post/badger-lmdb-boltdb/. I've written up my own comparison of the two focusing on characteristics _other_ than performance here: https://tech.townsourced.com/post/boltdb-vs-badger/.
-
-## Indexes
-
-Indexes allow you to skip checking any records that don't meet your index criteria. If you have 1000 records and only 10 of them are of the Division you want to deal with, then you don't need to check to see if the other 990 records match your query criteria if you create an index on the Division field. The downside of an index is added disk reads and writes on every write operation. For read heavy operations datasets, indexes can be very useful.
-
-In every BadgerHold store, there will be a reserved bucket _\_indexes_ which will be used to hold indexes that point back to another bucket's Key system. Indexes will be defined by setting the `badgerhold:"index"` struct tag on a field in a type.
-
-```Go
-type Person struct {
- Name string
- Division string `badgerhold:"index"`
-}
-
-// alternate struct tag if you wish to specify the index name
-type Person struct {
- Name string
- Division string `badgerholdIndex:"IdxDivision"`
-}
-```
-
-This means that there will be an index created for `Division` that will contain the set of unique divisions, and the main record keys they refer to.
-
-Optionally, you can implement the `Storer` interface, to specify your own indexes, rather than using the `badgerHoldIndex` struct tag.
-
-## Queries
-
-Queries are chain-able constructs that filters out any data that doesn't match it's criteria. An index will be used if the `.Index()` chain is called, otherwise BadgerHold won't use any index.
-
-Queries will look like this:
-
-```Go
-s.Find(&result, badgerhold.Where("FieldName").Eq(value).And("AnotherField").Lt(AnotherValue).Or(badgerhold.Where("FieldName").Eq(anotherValue)))
-```
-
-Fields must be exported, and thus always need to start with an upper-case letter. Available operators include:
-
-- Equal - `Where("field").Eq(value)`
-- Not Equal - `Where("field").Ne(value)`
-- Greater Than - `Where("field").Gt(value)`
-- Less Than - `Where("field").Lt(value)`
-- Less than or Equal To - `Where("field").Le(value)`
-- Greater Than or Equal To - `Where("field").Ge(value)`
-- In - `Where("field").In(val1, val2, val3)`
-- IsNil - `Where("field").IsNil()`
-- Regular Expression - `Where("field").RegExp(regexp.MustCompile("ea"))`
-- Matches Function - `Where("field").MatchFunc(func(ra *RecordAccess) (bool, error))`
-- Skip - `Where("field").Eq(value).Skip(10)`
-- Limit - `Where("field").Eq(value).Limit(10)`
-- SortBy - `Where("field").Eq(value).SortBy("field1", "field2")`
-- Reverse - `Where("field").Eq(value).SortBy("field").Reverse()`
-- Index - `Where("field").Eq(value).Index("indexName")`
-
-If you want to run a query's criteria against the Key value, you can use the `badgerhold.Key` constant:
-
-```Go
-store.Find(&result, badgerhold.Where(badgerhold.Key).Ne(value))
-```
-
-You can access nested structure fields in queries like this:
-
-```Go
-type Repo struct {
- Name string
- Contact ContactPerson
-}
-
-type ContactPerson struct {
- Name string
-}
-
-store.Find(&repo, badgerhold.Where("Contact.Name").Eq("some-name")
-```
-
-Instead of passing in a specific value to compare against in a query, you can compare against another field in the same struct. Consider the following struct:
-
-```Go
-type Person struct {
- Name string
- Birth time.Time
- Death time.Time
-}
-```
-
-If you wanted to find any invalid records where a Person's death was before their birth, you could do the following:
-
-```Go
-store.Find(&result, badgerhold.Where("Death").Lt(badgerhold.Field("Birth")))
-```
-
-Queries can be used in more than just selecting data. You can delete or update data that matches a query.
-
-Using the example above, if you wanted to remove all of the invalid records where Death < Birth:
-
-```Go
-// you must pass in a sample type, so BadgerHold knows which bucket to use and what indexes to update
-store.DeleteMatching(&Person{}, badgerhold.Where("Death").Lt(badgerhold.Field("Birth")))
-
-```
-
-Or if you wanted to update all the invalid records to flip/flop the Birth and Death dates:
-
-```Go
-
-store.UpdateMatching(&Person{}, badgerhold.Where("Death").Lt(badgerhold.Field("Birth")), func(record interface{}) error {
- update, ok := record.(*Person) // record will always be a pointer
- if !ok {
- return fmt.Errorf("Record isn't the correct type! Wanted Person, got %T", record)
- }
-
- update.Birth, update.Death = update.Death, update.Birth
-
- return nil
-})
-```
-
-### Keys in Structs
-
-A common scenario is to store the badgerhold Key in the same struct that is stored in the badgerDB value. You can automatically populate a record's Key in a struct by using the `badgerhold:"key"` struct tag when running `Find` queries.
-
-Another common scenario is to insert data with an auto-incrementing key assigned by the database. When performing an `Insert`, if the type of the key matches the type of the `badgerhold:"key"` tagged field, the data is passed in by reference, **and** the field's current value is the zero-value for that type, then it is set on the data _before_ insertion.
-
-```Go
-type Employee struct {
- ID uint64 `badgerhold:"key"`
- FirstName string
- LastName string
- Division string
- Hired time.Time
-}
-
-// old struct tag, currenty still supported but may be deprecated in the future
-type Employee struct {
- ID uint64 `badgerholdKey`
- FirstName string
- LastName string
- Division string
- Hired time.Time
-}
-```
-
-Badgerhold assumes only one of such struct tags exists. If a value already exists in the key field, it will be overwritten.
-
-If you want to insert an auto-incrementing Key you can pass the `badgerhold.NextSequence()` func as the Key value.
-
-```Go
-err := store.Insert(badgerhold.NextSequence(), data)
-```
-
-The key value will be a `uint64`.
-
-If you want to know the value of the auto-incrementing Key that was generated using `badgerhold.NextSequence()`, then make sure to pass a pointer to your data and that the `badgerholdKey` tagged field is of type `uint64`.
-
-```Go
-err := store.Insert(badgerhold.NextSequence(), &data)
-```
-
-### Unique Constraints
-
-You can create a unique constraint on a given field by using the `badgerhold:"unique"` struct tag:
-
-```Go
-type User struct {
- Name string
- Email string `badgerhold:"unique"` // this field will be indexed with a unique constraint
-}
-```
-
-The example above will only allow one record of type `User` to exist with a given `Email` field. Any insert, update or upsert that would violate that constraint will fail and return the `badgerhold.ErrUniqueExists` error.
-
-### Aggregate Queries
-
-Aggregate queries are queries that group results by a field. For example, lets say you had a collection of employees:
-
-```Go
-type Employee struct {
- FirstName string
- LastName string
- Division string
- Hired time.Time
-}
-```
-
-And you wanted to find the most senior (first hired) employee in each division:
-
-```Go
-result, err := store.FindAggregate(&Employee{}, nil, "Division") //nil query matches against all records
-```
-
-This will return a slice of `Aggregate Result` from which you can extract your groups and find Min, Max, Avg, Count, etc.
-
-```Go
-for i := range result {
- var division string
- employee := &Employee{}
-
- result[i].Group(&division)
- result[i].Min("Hired", employee)
-
- fmt.Printf("The most senior employee in the %s division is %s.\n",
- division, employee.FirstName + " " + employee.LastName)
-}
-```
-
-Aggregate queries become especially powerful when combined with the sub-querying capability of `MatchFunc`.
-
-Many more examples of queries can be found in the [find_test.go](https://github.com/timshannon/badgerhold/blob/master/find_test.go) file in this repository.
-
-## Comparing
-
-Just like with Go, types must be the same in order to be compared with each other. You cannot compare an int to a int32. The built-in Go comparable types (ints, floats, strings, etc) will work as expected. Other types from the standard library can also be compared such as `time.Time`, `big.Rat`, `big.Int`, and `big.Float`. If there are other standard library types that I missed, let me know.
-
-You can compare any custom type either by using the `MatchFunc` criteria, or by satisfying the `Comparer` interface with your type by adding the Compare method: `Compare(other interface{}) (int, error)`.
-
-If a type doesn't have a predefined comparer, and doesn't satisfy the Comparer interface, then the types value is converted to a string and compared lexicographically.
-
-## Behavior Changes
-
-Since BadgerHold is a higher level interface than Badger DB, there are some added helpers. Instead of _Put_, you have the options of:
-
-- _Insert_ - Fails if key already exists.
-- _Update_ - Fails if key doesn't exist `ErrNotFound`.
-- _Upsert_ - If key doesn't exist, it inserts the data, otherwise it updates the existing record.
-
-When getting data instead of returning `nil` if a value doesn't exist, BadgerHold returns `badgerhold.ErrNotFound`, and similarly when deleting data, instead of silently continuing if a value isn't found to delete, BadgerHold returns `badgerhold.ErrNotFound`. The exception to this is when using query based functions such as `Find` (returns an empty slice), `DeleteMatching` and `UpdateMatching` where no error is returned.
-
-## When should I use BadgerHold?
-
-BadgerHold will be useful in the same scenarios where BadgerDB is useful, with the added benefit of being able to retire some of your data filtering code and possibly improved performance.
-
-You can also use it instead of SQLite for many scenarios. BadgerHold's main benefit over SQLite is its simplicity when working with Go Types. There is no need for an ORM layer to translate records to types, simply put types in, and get types out. You also don't have to deal with database initialization. Usually with SQLite you'll need several scripts to create the database, create the tables you expect, and create any indexes. With BadgerHold you simply open a new file and put any type of data you want in it.
-
-```Go
-options := badgerhold.DefaultOptions
-options.Dir = "data"
-options.ValueDir = "data"
-
-store, err := badgerhold.Open(options)
-defer store.Close()
-if err != nil {
- // handle error
- log.Fatal(err)
-}
-
-
-err = store.Insert("key", &Item{
- Name: "Test Name",
- Created: time.Now(),
-})
-```
-
-That's it!
-
-Badgerhold currently has over 80% coverage in unit tests, and it's backed by BadgerDB which is a very solid and well built piece of software, so I encourage you to give it a try.
-
-If you end up using BadgerHold, I'd love to hear about it.

-/*
-Package badgerhold is an indexing and querying layer on top of a badger DB. The goal is to allow easy, persistent storage
-and retrieval of Go types. badgerDB is an embedded key-value store, and badgerhold serves a similar use case however with
-a higher level interface for common uses of Badger.
-
-Go Types
-
-BadgerHold deals directly with Go Types. When inserting data, you pass in your structure directly. When querying data you
-pass in a pointer to a slice of the type you want to return. By default Gob encoding is used. You can put multiple
-different types into the same DB file and they (and their indexes) will be stored separately.
-
- err := store.Insert(1234, Item{
- Name: "Test Name",
- Created: time.Now(),
- })
-
- var result []Item
-
- err := store.Find(&result, query)
-
-
-Indexes
-
-BadgerHold will automatically create an index for any struct fields tags with "badgerholdIndex"
-
- type Item struct {
- ID int
- Name string
- Category string `badgerholdIndex:"Category"`
- Created time.Time
- }
-
-The first field specified in query will be used as the index (if one exists).
-
-Queries are chained together criteria that applies to a set of fields:
-
- badgerhold.Where("Name").Eq("John Doe").And("DOB").Lt(time.Now())

-GopherLua is a Lua5.1 VM and compiler written in Go. GopherLua has a same goal
-with Lua: **Be a scripting language with extensible semantics** . It provides
-Go APIs that allow you to easily embed a scripting language to your Go host
-programs.
-
-.. contents::
- :depth: 1
-
-----------------------------------------------------------------
-Design principle
-----------------------------------------------------------------
-
-- Be a scripting language with extensible semantics.
-- User-friendly Go API
- - The stack based API like the one used in the original Lua
- implementation will cause a performance improvements in GopherLua
- (It will reduce memory allocations and concrete type <-> interface conversions).
- GopherLua API is **not** the stack based API.
- GopherLua give preference to the user-friendliness over the performance.
-
-----------------------------------------------------------------
-How about performance?
-----------------------------------------------------------------
-GopherLua is not fast but not too slow, I think.
-
-GopherLua has almost equivalent ( or little bit better ) performance as Python3 on micro benchmarks.
-
-There are some benchmarks on the `wiki page `_ .
-
-----------------------------------------------------------------
-Installation
-----------------------------------------------------------------
-
-.. code-block:: bash
-
- go get github.com/yuin/gopher-lua
-
-GopherLua supports >= Go1.9.
-
-----------------------------------------------------------------
-Usage
-----------------------------------------------------------------
-GopherLua APIs perform in much the same way as Lua, **but the stack is used only
-for passing arguments and receiving returned values.**
-
-GopherLua supports channel operations. See **"Goroutines"** section.
-
-Import a package.
-
-.. code-block:: go
-
- import (
- "github.com/yuin/gopher-lua"
- )
-
-Run scripts in the VM.
-
-.. code-block:: go
-
- L := lua.NewState()
- defer L.Close()
- if err := L.DoString(`print("hello")`); err != nil {
- panic(err)
- }
-
-.. code-block:: go
-
- L := lua.NewState()
- defer L.Close()
- if err := L.DoFile("hello.lua"); err != nil {
- panic(err)
- }
-
-Refer to `Lua Reference Manual `_ for further information.
-
-Note that elements that are not commented in `Go doc `_ equivalent to `Lua Reference Manual `_ for further information.
-
-+++++++++++++++++++++++++++++++++++++++++
-Calling Go from Lua
-+++++++++++++++++++++++++++++++++++++++++
-
-.. code-block:: go
-
- func Double(L *lua.LState) int {
- lv := L.ToInt(1) /* get argument */
- L.Push(lua.LNumber(lv * 2)) /* push result */
- return 1 /* number of results */
- }
-
- func main() {
- L := lua.NewState()
- defer L.Close()
- L.SetGlobal("double", L.NewFunction(Double)) /* Original lua_setglobal uses stack... */
- }
-
-.. code-block:: lua
-
- print(double(20)) -- > "40"
-
-Any function registered with GopherLua is a ``lua.LGFunction``, defined in ``value.go``
-
-.. code-block:: go
-
- type LGFunction func(*LState) int
-
-Working with coroutines.
-
-.. code-block:: go
-
- co, _ := L.NewThread() /* create a new thread */
- fn := L.GetGlobal("coro").(*lua.LFunction) /* get function from lua */
- for {
- st, err, values := L.Resume(co, fn)
- if st == lua.ResumeError {
- fmt.Println("yield break(error)")
- fmt.Println(err.Error())
- break
- }
-
- for i, lv := range values {
- fmt.Printf("%v : %v\n", i, lv)
- }
-
- if st == lua.ResumeOK {
- fmt.Println("yield break(ok)")
- break
- }
- }
-
-+++++++++++++++++++++++++++++++++++++++++
-Opening a subset of builtin modules
-+++++++++++++++++++++++++++++++++++++++++
-
-The following demonstrates how to open a subset of the built-in modules in Lua, say for example to avoid enabling modules with access to local files or system calls.
-
-main.go
-
-.. code-block:: go
-
- func main() {
- L := lua.NewState(lua.Options{SkipOpenLibs: true})
- defer L.Close()
- for _, pair := range []struct {
- n string
- f lua.LGFunction
- }{
- {lua.LoadLibName, lua.OpenPackage}, // Must be first
- {lua.BaseLibName, lua.OpenBase},
- {lua.TabLibName, lua.OpenTable},
- } {
- if err := L.CallByParam(lua.P{
- Fn: L.NewFunction(pair.f),
- NRet: 0,
- Protect: true,
- }, lua.LString(pair.n)); err != nil {
- panic(err)
- }
- }
- if err := L.DoFile("main.lua"); err != nil {
- panic(err)
- }
- }
-
-+++++++++++++++++++++++++++++++++++++++++
-Creating a module by Go
-+++++++++++++++++++++++++++++++++++++++++
-
-mymodule.go
-
-.. code-block:: go
-
- package mymodule
-
- import (
- "github.com/yuin/gopher-lua"
- )
-
- func Loader(L *lua.LState) int {
- // register functions to the table
- mod := L.SetFuncs(L.NewTable(), exports)
- // register other stuff
- L.SetField(mod, "name", lua.LString("value"))
-
- // returns the module
- L.Push(mod)
- return 1
- }
-
- var exports = map[string]lua.LGFunction{
- "myfunc": myfunc,
- }
-
- func myfunc(L *lua.LState) int {
- return 0
- }
-
-mymain.go
-
-.. code-block:: go
-
- package main
-
- import (
- "./mymodule"
- "github.com/yuin/gopher-lua"
- )
-
- func main() {
- L := lua.NewState()
- defer L.Close()
- L.PreloadModule("mymodule", mymodule.Loader)
- if err := L.DoFile("main.lua"); err != nil {
- panic(err)
- }
- }
-
-main.lua
-
-.. code-block:: lua
-
- local m = require("mymodule")
- m.myfunc()
- print(m.name)
-
-
-+++++++++++++++++++++++++++++++++++++++++
-Calling Lua from Go
-+++++++++++++++++++++++++++++++++++++++++
-
-.. code-block:: go
-
- L := lua.NewState()
- defer L.Close()
- if err := L.DoFile("double.lua"); err != nil {
- panic(err)
- }
- if err := L.CallByParam(lua.P{
- Fn: L.GetGlobal("double"),
- NRet: 1,
- Protect: true,
- }, lua.LNumber(10)); err != nil {
- panic(err)
- }
- ret := L.Get(-1) // returned value
- L.Pop(1) // remove received value
-
-If ``Protect`` is false, GopherLua will panic instead of returning an ``error`` value.
-
-+++++++++++++++++++++++++++++++++++++++++
-User-Defined types
-+++++++++++++++++++++++++++++++++++++++++
-You can extend GopherLua with new types written in Go.
-``LUserData`` is provided for this purpose.
-
-.. code-block:: go
-
- type Person struct {
- Name string
- }
-
- const luaPersonTypeName = "person"
-
- // Registers my person type to given L.
- func registerPersonType(L *lua.LState) {
- mt := L.NewTypeMetatable(luaPersonTypeName)
- L.SetGlobal("person", mt)
- // static attributes
- L.SetField(mt, "new", L.NewFunction(newPerson))
- // methods
- L.SetField(mt, "__index", L.SetFuncs(L.NewTable(), personMethods))
- }
-
- // Constructor
- func newPerson(L *lua.LState) int {
- person := &Person{L.CheckString(1)}
- ud := L.NewUserData()
- ud.Value = person
- L.SetMetatable(ud, L.GetTypeMetatable(luaPersonTypeName))
- L.Push(ud)
- return 1
- }
-
- // Checks whether the first lua argument is a *LUserData with *Person and returns this *Person.
- func checkPerson(L *lua.LState) *Person {
- ud := L.CheckUserData(1)
- if v, ok := ud.Value.(*Person); ok {
- return v
- }
- L.ArgError(1, "person expected")
- return nil
- }
-
- var personMethods = map[string]lua.LGFunction{
- "name": personGetSetName,
- }
-
- // Getter and setter for the Person#Name
- func personGetSetName(L *lua.LState) int {
- p := checkPerson(L)
- if L.GetTop() == 2 {
- p.Name = L.CheckString(2)
- return 0
- }
- L.Push(lua.LString(p.Name))
- return 1
- }
-
- func main() {
- L := lua.NewState()
- defer L.Close()
- registerPersonType(L)
- if err := L.DoString(`
- p = person.new("Steeve")
- print(p:name()) -- "Steeve"
- p:name("Alice")
- print(p:name()) -- "Alice"
- `); err != nil {
- panic(err)
- }
- }
-
-+++++++++++++++++++++++++++++++++++++++++
-Terminating a running LState
-+++++++++++++++++++++++++++++++++++++++++
-GopherLua supports the `Go Concurrency Patterns: Context `_ .
-
-
-.. code-block:: go
-
- L := lua.NewState()
- defer L.Close()
- ctx, cancel := context.WithTimeout(context.Background(), 1*time.Second)
- defer cancel()
- // set the context to our LState
- L.SetContext(ctx)
- err := L.DoString(`
- local clock = os.clock
- function sleep(n) -- seconds
- local t0 = clock()
- while clock() - t0 <= n do end
- end
- sleep(3)
- `)
- // err.Error() contains "context deadline exceeded"
-
-With coroutines
-
-.. code-block:: go
-
- L := lua.NewState()
- defer L.Close()
- ctx, cancel := context.WithCancel(context.Background())
- L.SetContext(ctx)
- defer cancel()
- L.DoString(`
- function coro()
- local i = 0
- while true do
- coroutine.yield(i)
- i = i+1
- end
- return i
- end
- `)
- co, cocancel := L.NewThread()
- defer cocancel()
- fn := L.GetGlobal("coro").(*LFunction)
-
- _, err, values := L.Resume(co, fn) // err is nil
-
- cancel() // cancel the parent context
-
- _, err, values = L.Resume(co, fn) // err is NOT nil : child context was canceled
-
-**Note that using a context causes performance degradation.**
-
-.. code-block::
-
- time ./glua-with-context.exe fib.lua
- 9227465
- 0.01s user 0.11s system 1% cpu 7.505 total

-
-+++++++++++++++++++++++++++++++++++++++++
-Sharing Lua byte code between LStates
-+++++++++++++++++++++++++++++++++++++++++
-Calling ``DoFile`` will load a Lua script, compile it to byte code and run the byte code in a ``LState``.
-
-If you have multiple ``LStates`` which are all required to run the same script, you can share the byte code between them,
-which will save on memory.
-Sharing byte code is safe as it is read only and cannot be altered by lua scripts.
-
-.. code-block:: go
-
- // CompileLua reads the passed lua file from disk and compiles it.
- func CompileLua(filePath string) (*lua.FunctionProto, error) {
- file, err := os.Open(filePath)
- defer file.Close()
- if err != nil {
- return nil, err
- }
- reader := bufio.NewReader(file)
- chunk, err := parse.Parse(reader, filePath)
- if err != nil {
- return nil, err
- }
- proto, err := lua.Compile(chunk, filePath)
- if err != nil {
- return nil, err
- }
- return proto, nil
- }
-
- // DoCompiledFile takes a FunctionProto, as returned by CompileLua, and runs it in the LState. It is equivalent
- // to calling DoFile on the LState with the original source file.
- func DoCompiledFile(L *lua.LState, proto *lua.FunctionProto) error {
- lfunc := L.NewFunctionFromProto(proto)
- L.Push(lfunc)
- return L.PCall(0, lua.MultRet, nil)
- }
-
- // Example shows how to share the compiled byte code from a lua script between multiple VMs.
- func Example() {
- codeToShare := CompileLua("mylua.lua")
- a := lua.NewState()
- b := lua.NewState()
- c := lua.NewState()
- DoCompiledFile(a, codeToShare)
- DoCompiledFile(b, codeToShare)
- DoCompiledFile(c, codeToShare)
- }
-
-+++++++++++++++++++++++++++++++++++++++++
-Goroutines
-+++++++++++++++++++++++++++++++++++++++++
-The ``LState`` is not goroutine-safe. It is recommended to use one LState per goroutine and communicate between goroutines by using channels.
-
-Channels are represented by ``channel`` objects in GopherLua. And a ``channel`` table provides functions for performing channel operations.
-
-Some objects can not be sent over channels due to having non-goroutine-safe objects inside itself.
-
-- a thread(state)
-- a function
-- an userdata
-- a table with a metatable
-
-You **must not** send these objects from Go APIs to channels.
-
-
-
-.. code-block:: go
-
- func receiver(ch, quit chan lua.LValue) {
- L := lua.NewState()
- defer L.Close()
- L.SetGlobal("ch", lua.LChannel(ch))
- L.SetGlobal("quit", lua.LChannel(quit))
- if err := L.DoString(`
- local exit = false
- while not exit do
- channel.select(
- {"|<-", ch, function(ok, v)
- if not ok then
- print("channel closed")
- exit = true
- else
- print("received:", v)
- end
- end},
- {"|<-", quit, function(ok, v)
- print("quit")
- exit = true
- end}
- )
- end
- `); err != nil {
- panic(err)
- }
- }
-
- func sender(ch, quit chan lua.LValue) {
- L := lua.NewState()
- defer L.Close()
- L.SetGlobal("ch", lua.LChannel(ch))
- L.SetGlobal("quit", lua.LChannel(quit))
- if err := L.DoString(`
- ch:send("1")
- ch:send("2")
- `); err != nil {
- panic(err)
- }
- ch <- lua.LString("3")
- quit <- lua.LTrue
- }
-
- func main() {
- ch := make(chan lua.LValue)
- quit := make(chan lua.LValue)
- go receiver(ch, quit)
- go sender(ch, quit)
- time.Sleep(3 * time.Second)
- }
-
-'''''''''''''''
-Go API
-'''''''''''''''
-
-``ToChannel``, ``CheckChannel``, ``OptChannel`` are available.
-
-Refer to `Go doc(LState methods) `_ for further information.
-
-'''''''''''''''
-Lua API
-'''''''''''''''
-
-- **channel.make([buf:int]) -> ch:channel**
- - Create new channel that has a buffer size of ``buf``. By default, ``buf`` is 0.
-
-- **channel.select(case:table [, case:table, case:table ...]) -> {index:int, recv:any, ok}**
- - Same as the ``select`` statement in Go. It returns the index of the chosen case and, if that
- case was a receive operation, the value received and a boolean indicating whether the channel has been closed.
- - ``case`` is a table that outlined below.
- - receiving: `{"|<-", ch:channel [, handler:func(ok, data:any)]}`
- - sending: `{"<-|", ch:channel, data:any [, handler:func(data:any)]}`
- - default: `{"default" [, handler:func()]}`
-
-``channel.select`` examples:
-
-.. code-block:: lua
-
- local idx, recv, ok = channel.select(
- {"|<-", ch1},
- {"|<-", ch2}
- )
- if not ok then
- print("closed")
- elseif idx == 1 then -- received from ch1
- print(recv)
- elseif idx == 2 then -- received from ch2
- print(recv)
- end
-
-.. code-block:: lua
-
- channel.select(
- {"|<-", ch1, function(ok, data)
- print(ok, data)
- end},
- {"<-|", ch2, "value", function(data)
- print(data)
- end},
- {"default", function()
- print("default action")
- end}
- )
-
-- **channel:send(data:any)**
- - Send ``data`` over the channel.
-- **channel:receive() -> ok:bool, data:any**
- - Receive some data over the channel.
-- **channel:close()**
- - Close the channel.
-
-''''''''''''''''''''''''''''''
-The LState pool pattern
-''''''''''''''''''''''''''''''
-To create per-thread LState instances, You can use the ``sync.Pool`` like mechanism.
-
-.. code-block:: go
-
- type lStatePool struct {
- m sync.Mutex
- saved []*lua.LState
- }
-
- func (pl *lStatePool) Get() *lua.LState {
- pl.m.Lock()
- defer pl.m.Unlock()
- n := len(pl.saved)
- if n == 0 {
- return pl.New()
- }
- x := pl.saved[n-1]
- pl.saved = pl.saved[0 : n-1]
- return x
- }
-
- func (pl *lStatePool) New() *lua.LState {
- L := lua.NewState()
- // setting the L up here.
- // load scripts, set global variables, share channels, etc...
- return L
- }
-
- func (pl *lStatePool) Put(L *lua.LState) {
- pl.m.Lock()
- defer pl.m.Unlock()
- pl.saved = append(pl.saved, L)
- }
-
- func (pl *lStatePool) Shutdown() {
- for _, L := range pl.saved {
- L.Close()
- }
- }
-
- // Global LState pool
- var luaPool = &lStatePool{
- saved: make([]*lua.LState, 0, 4),
- }
-
-Now, you can get per-thread LState objects from the ``luaPool`` .
-
-.. code-block:: go
-
- func MyWorker() {
- L := luaPool.Get()
- defer luaPool.Put(L)
- /* your code here */
- }
-
- func main() {
- defer luaPool.Shutdown()
- go MyWorker()
- go MyWorker()
- /* etc... */
- }

-
-bbolt is a fork of [Ben Johnson's][gh_ben] [Bolt][bolt] key/value
-store. The purpose of this fork is to provide the Go community with an active
-maintenance and development target for Bolt; the goal is improved reliability
-and stability. bbolt includes bug fixes, performance enhancements, and features
-not found in Bolt while preserving backwards compatibility with the Bolt API.
-
-Bolt is a pure Go key/value store inspired by [Howard Chu's][hyc_symas]
-[LMDB project][lmdb]. The goal of the project is to provide a simple,
-fast, and reliable database for projects that don't require a full database
-server such as Postgres or MySQL.
-
-Since Bolt is meant to be used as such a low-level piece of functionality,
-simplicity is key. The API will be small and only focus on getting values
-and setting values. That's it.

-[lmdb]: http://symas.com/mdb/
-
-## Project Status
-
-Bolt is stable, the API is fixed, and the file format is fixed. Full unit
-test coverage and randomized black box testing are used to ensure database
-consistency and thread safety. Bolt is currently used in high-load production
-environments serving databases as large as 1TB. Many companies such as
-Shopify and Heroku use Bolt-backed services every day.
-
-## Project versioning
-
-bbolt uses [semantic versioning](http://semver.org).
-API should not change between patch and minor releases.
-New minor versions may add additional features to the API.

-
-## Getting Started
-
-### Installing
-
-To start using Bolt, install Go and run `go get`:
-
-```sh
-$ go get go.etcd.io/bbolt/...
-```
-
-This will retrieve the library and install the `bolt` command line utility into
-your `$GOBIN` path.
-
-
-### Importing bbolt
-
-To use bbolt as an embedded key-value store, import as:
-
-```go
-import bolt "go.etcd.io/bbolt"
-
-db, err := bolt.Open(path, 0666, nil)
-if err != nil {
- return err
-}
-defer db.Close()
-```
-
-
-### Opening a database
-
-The top-level object in Bolt is a `DB`. It is represented as a single file on
-your disk and represents a consistent snapshot of your data.
-
-To open your database, simply use the `bolt.Open()` function:
-
-```go
-package main
-
-import (
- "log"
-
- bolt "go.etcd.io/bbolt"
-)
-
-func main() {
- // Open the my.db data file in your current directory.
- // It will be created if it doesn't exist.
- db, err := bolt.Open("my.db", 0600, nil)
- if err != nil {
- log.Fatal(err)
- }
- defer db.Close()
-
- ...
-}
-```
-
-Please note that Bolt obtains a file lock on the data file so multiple processes
-cannot open the same database at the same time. Opening an already open Bolt
-database will cause it to hang until the other process closes it. To prevent
-an indefinite wait you can pass a timeout option to the `Open()` function:
-
-```go
-db, err := bolt.Open("my.db", 0600, &bolt.Options{Timeout: 1 * time.Second})
-```
-
-
-### Transactions
-
-Bolt allows only one read-write transaction at a time but allows as many
-read-only transactions as you want at a time. Each transaction has a consistent
-view of the data as it existed when the transaction started.
-
-Individual transactions and all objects created from them (e.g. buckets, keys)
-are not thread safe. To work with data in multiple goroutines you must start
-a transaction for each one or use locking to ensure only one goroutine accesses
-a transaction at a time. Creating transaction from the `DB` is thread safe.
-
-Transactions should not depend on one another and generally shouldn't be opened
-simultaneously in the same goroutine. This can cause a deadlock as the read-write
-transaction needs to periodically re-map the data file but it cannot do so while
-any read-only transaction is open. Even a nested read-only transaction can cause
-a deadlock, as the child transaction can block the parent transaction from releasing
-its resources.
-
-#### Read-write transactions
-
-To start a read-write transaction, you can use the `DB.Update()` function:
-
-```go
-err := db.Update(func(tx *bolt.Tx) error {
- ...
- return nil
-})
-```
-
-Inside the closure, you have a consistent view of the database. You commit the
-transaction by returning `nil` at the end. You can also rollback the transaction
-at any point by returning an error. All database operations are allowed inside
-a read-write transaction.
-
-Always check the return error as it will report any disk failures that can cause
-your transaction to not complete. If you return an error within your closure
-it will be passed through.
-
-
-#### Read-only transactions
-
-To start a read-only transaction, you can use the `DB.View()` function:
-
-```go
-err := db.View(func(tx *bolt.Tx) error {
- ...
- return nil
-})
-```
-
-You also get a consistent view of the database within this closure, however,
-no mutating operations are allowed within a read-only transaction. You can only
-retrieve buckets, retrieve values, and copy the database within a read-only
-transaction.
-
-
-#### Batch read-write transactions
-
-Each `DB.Update()` waits for disk to commit the writes. This overhead
-can be minimized by combining multiple updates with the `DB.Batch()`
-function:
-
-```go
-err := db.Batch(func(tx *bolt.Tx) error {
- ...
- return nil
-})
-```
-
-Concurrent Batch calls are opportunistically combined into larger
-transactions. Batch is only useful when there are multiple goroutines
-calling it.
-
-The trade-off is that `Batch` can call the given
-function multiple times, if parts of the transaction fail. The
-function must be idempotent and side effects must take effect only
-after a successful return from `DB.Batch()`.
-
-For example: don't display messages from inside the function, instead
-set variables in the enclosing scope:
-
-```go
-var id uint64
-err := db.Batch(func(tx *bolt.Tx) error {
- // Find last key in bucket, decode as bigendian uint64, increment
- // by one, encode back to []byte, and add new key.
- ...
- id = newValue
- return nil
-})
-if err != nil {
- return ...
-}
-fmt.Println("Allocated ID %d", id)
-```
-
-
-#### Managing transactions manually
-
-The `DB.View()` and `DB.Update()` functions are wrappers around the `DB.Begin()`
-function. These helper functions will start the transaction, execute a function,
-and then safely close your transaction if an error is returned. This is the
-recommended way to use Bolt transactions.
-
-However, sometimes you may want to manually start and end your transactions.
-You can use the `DB.Begin()` function directly but **please** be sure to close
-the transaction.
-
-```go
-// Start a writable transaction.
-tx, err := db.Begin(true)
-if err != nil {
- return err
-}
-defer tx.Rollback()
-
-// Use the transaction...
-_, err := tx.CreateBucket([]byte("MyBucket"))
-if err != nil {
- return err
-}
-
-// Commit the transaction and check for error.
-if err := tx.Commit(); err != nil {
- return err
-}
-```
-
-The first argument to `DB.Begin()` is a boolean stating if the transaction
-should be writable.
-
-
-### Using buckets
-
-Buckets are collections of key/value pairs within the database. All keys in a
-bucket must be unique. You can create a bucket using the `Tx.CreateBucket()`
-function:
-
-```go
-db.Update(func(tx *bolt.Tx) error {
- b, err := tx.CreateBucket([]byte("MyBucket"))
- if err != nil {
- return fmt.Errorf("create bucket: %s", err)
- }
- return nil
-})
-```
-
-You can also create a bucket only if it doesn't exist by using the
-`Tx.CreateBucketIfNotExists()` function. It's a common pattern to call this
-function for all your top-level buckets after you open your database so you can
-guarantee that they exist for future transactions.
-
-To delete a bucket, simply call the `Tx.DeleteBucket()` function.
-
-
-### Using key/value pairs
-
-To save a key/value pair to a bucket, use the `Bucket.Put()` function:
-
-```go
-db.Update(func(tx *bolt.Tx) error {
- b := tx.Bucket([]byte("MyBucket"))
- err := b.Put([]byte("answer"), []byte("42"))
- return err
-})
-```
-
-This will set the value of the `"answer"` key to `"42"` in the `MyBucket`
-bucket. To retrieve this value, we can use the `Bucket.Get()` function:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- b := tx.Bucket([]byte("MyBucket"))
- v := b.Get([]byte("answer"))
- fmt.Printf("The answer is: %s\n", v)
- return nil
-})
-```
-
-The `Get()` function does not return an error because its operation is
-guaranteed to work (unless there is some kind of system failure). If the key
-exists then it will return its byte slice value. If it doesn't exist then it
-will return `nil`. It's important to note that you can have a zero-length value
-set to a key which is different than the key not existing.
-
-Use the `Bucket.Delete()` function to delete a key from the bucket.
-
-Please note that values returned from `Get()` are only valid while the
-transaction is open. If you need to use a value outside of the transaction
-then you must use `copy()` to copy it to another byte slice.
-
-
-### Autoincrementing integer for the bucket
-By using the `NextSequence()` function, you can let Bolt determine a sequence
-which can be used as the unique identifier for your key/value pairs. See the
-example below.
-
-```go
-// CreateUser saves u to the store. The new user ID is set on u once the data is persisted.
-func (s *Store) CreateUser(u *User) error {
- return s.db.Update(func(tx *bolt.Tx) error {
- // Retrieve the users bucket.
- // This should be created when the DB is first opened.
- b := tx.Bucket([]byte("users"))
-
- // Generate ID for the user.
- // This returns an error only if the Tx is closed or not writeable.
- // That can't happen in an Update() call so I ignore the error check.
- id, _ := b.NextSequence()
- u.ID = int(id)
-
- // Marshal user data into bytes.
- buf, err := json.Marshal(u)
- if err != nil {
- return err
- }
-
- // Persist bytes to users bucket.
- return b.Put(itob(u.ID), buf)
- })
-}
-
-// itob returns an 8-byte big endian representation of v.
-func itob(v int) []byte {
- b := make([]byte, 8)
- binary.BigEndian.PutUint64(b, uint64(v))
- return b
-}
-
-type User struct {
- ID int
- ...
-}
-```
-
-### Iterating over keys
-
-Bolt stores its keys in byte-sorted order within a bucket. This makes sequential
-iteration over these keys extremely fast. To iterate over keys we'll use a
-`Cursor`:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- // Assume bucket exists and has keys
- b := tx.Bucket([]byte("MyBucket"))
-
- c := b.Cursor()
-
- for k, v := c.First(); k != nil; k, v = c.Next() {
- fmt.Printf("key=%s, value=%s\n", k, v)
- }
-
- return nil
-})
-```
-
-The cursor allows you to move to a specific point in the list of keys and move
-forward or backward through the keys one at a time.
-
-The following functions are available on the cursor:
-
-```
-First() Move to the first key.
-Last() Move to the last key.
-Seek() Move to a specific key.
-Next() Move to the next key.
-Prev() Move to the previous key.
-```
-
-Each of those functions has a return signature of `(key []byte, value []byte)`.
-When you have iterated to the end of the cursor then `Next()` will return a
-`nil` key. You must seek to a position using `First()`, `Last()`, or `Seek()`
-before calling `Next()` or `Prev()`. If you do not seek to a position then
-these functions will return a `nil` key.
-
-During iteration, if the key is non-`nil` but the value is `nil`, that means
-the key refers to a bucket rather than a value. Use `Bucket.Bucket()` to
-access the sub-bucket.
-
-
-#### Prefix scans
-
-To iterate over a key prefix, you can combine `Seek()` and `bytes.HasPrefix()`:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- // Assume bucket exists and has keys
- c := tx.Bucket([]byte("MyBucket")).Cursor()
-
- prefix := []byte("1234")
- for k, v := c.Seek(prefix); k != nil && bytes.HasPrefix(k, prefix); k, v = c.Next() {
- fmt.Printf("key=%s, value=%s\n", k, v)
- }
-
- return nil
-})
-```
-
-#### Range scans
-
-Another common use case is scanning over a range such as a time range. If you
-use a sortable time encoding such as RFC3339 then you can query a specific
-date range like this:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- // Assume our events bucket exists and has RFC3339 encoded time keys.
- c := tx.Bucket([]byte("Events")).Cursor()
-
- // Our time range spans the 90's decade.
- min := []byte("1990-01-01T00:00:00Z")
- max := []byte("2000-01-01T00:00:00Z")
-
- // Iterate over the 90's.
- for k, v := c.Seek(min); k != nil && bytes.Compare(k, max) <= 0; k, v = c.Next() {
- fmt.Printf("%s: %s\n", k, v)
- }
-
- return nil
-})
-```
-
-Note that, while RFC3339 is sortable, the Golang implementation of RFC3339Nano does not use a fixed number of digits after the decimal point and is therefore not sortable.
-
-
-#### ForEach()
-
-You can also use the function `ForEach()` if you know you'll be iterating over
-all the keys in a bucket:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- // Assume bucket exists and has keys
- b := tx.Bucket([]byte("MyBucket"))
-
- b.ForEach(func(k, v []byte) error {
- fmt.Printf("key=%s, value=%s\n", k, v)
- return nil
- })
- return nil
-})
-```
-
-Please note that keys and values in `ForEach()` are only valid while
-the transaction is open. If you need to use a key or value outside of
-the transaction, you must use `copy()` to copy it to another byte
-slice.
-
-### Nested buckets
-
-You can also store a bucket in a key to create nested buckets. The API is the
-same as the bucket management API on the `DB` object:
-
-```go
-func (*Bucket) CreateBucket(key []byte) (*Bucket, error)
-func (*Bucket) CreateBucketIfNotExists(key []byte) (*Bucket, error)
-func (*Bucket) DeleteBucket(key []byte) error
-```
-
-Say you had a multi-tenant application where the root level bucket was the account bucket. Inside of this bucket was a sequence of accounts which themselves are buckets. And inside the sequence bucket you could have many buckets pertaining to the Account itself (Users, Notes, etc) isolating the information into logical groupings.
-
-```go
-
-// createUser creates a new user in the given account.
-func createUser(accountID int, u *User) error {
- // Start the transaction.
- tx, err := db.Begin(true)
- if err != nil {
- return err
- }
- defer tx.Rollback()
-
- // Retrieve the root bucket for the account.
- // Assume this has already been created when the account was set up.
- root := tx.Bucket([]byte(strconv.FormatUint(accountID, 10)))
-
- // Setup the users bucket.
- bkt, err := root.CreateBucketIfNotExists([]byte("USERS"))
- if err != nil {
- return err
- }
-
- // Generate an ID for the new user.
- userID, err := bkt.NextSequence()
- if err != nil {
- return err
- }
- u.ID = userID
-
- // Marshal and save the encoded user.
- if buf, err := json.Marshal(u); err != nil {
- return err
- } else if err := bkt.Put([]byte(strconv.FormatUint(u.ID, 10)), buf); err != nil {
- return err
- }
-
- // Commit the transaction.
- if err := tx.Commit(); err != nil {
- return err
- }
-
- return nil
-}
-
-```
-
-
-
-
-### Database backups
-
-Bolt is a single file so it's easy to backup. You can use the `Tx.WriteTo()`
-function to write a consistent view of the database to a writer. If you call
-this from a read-only transaction, it will perform a hot backup and not block
-your other database reads and writes.
-
-By default, it will use a regular file handle which will utilize the operating
-system's page cache. See the [`Tx`](https://godoc.org/go.etcd.io/bbolt#Tx)
-documentation for information about optimizing for larger-than-RAM datasets.
-
-One common use case is to backup over HTTP so you can use tools like `cURL` to
-do database backups:
-
-```go
-func BackupHandleFunc(w http.ResponseWriter, req *http.Request) {
- err := db.View(func(tx *bolt.Tx) error {
- w.Header().Set("Content-Type", "application/octet-stream")
- w.Header().Set("Content-Disposition", `attachment; filename="my.db"`)
- w.Header().Set("Content-Length", strconv.Itoa(int(tx.Size())))
- _, err := tx.WriteTo(w)
- return err
- })
- if err != nil {
- http.Error(w, err.Error(), http.StatusInternalServerError)
- }
-}
-```
-
-Then you can backup using this command:
-
-```sh
-$ curl http://localhost/backup > my.db
-```
-
-Or you can open your browser to `http://localhost/backup` and it will download
-automatically.
-
-If you want to backup to another file you can use the `Tx.CopyFile()` helper
-function.
-
-
-### Statistics
-
-The database keeps a running count of many of the internal operations it
-performs so you can better understand what's going on. By grabbing a snapshot
-of these stats at two points in time we can see what operations were performed
-in that time range.
-
-For example, we could start a goroutine to log stats every 10 seconds:
-
-```go
-go func() {
- // Grab the initial stats.
- prev := db.Stats()
-
- for {
- // Wait for 10s.
- time.Sleep(10 * time.Second)
-
- // Grab the current stats and diff them.
- stats := db.Stats()
- diff := stats.Sub(&prev)
-
- // Encode stats to JSON and print to STDERR.
- json.NewEncoder(os.Stderr).Encode(diff)
-
- // Save stats for the next loop.
- prev = stats
- }
-}()
-```
-
-It's also useful to pipe these stats to a service such as statsd for monitoring
-or to provide an HTTP endpoint that will perform a fixed-length sample.
-
-
-### Read-Only Mode
-
-Sometimes it is useful to create a shared, read-only Bolt database. To this,
-set the `Options.ReadOnly` flag when opening your database. Read-only mode
-uses a shared lock to allow multiple processes to read from the database but
-it will block any processes from opening the database in read-write mode.
-
-```go
-db, err := bolt.Open("my.db", 0666, &bolt.Options{ReadOnly: true})
-if err != nil {
- log.Fatal(err)
-}
-```
-
-### Mobile Use (iOS/Android)
-
-Bolt is able to run on mobile devices by leveraging the binding feature of the
-[gomobile](https://github.com/golang/mobile) tool. Create a struct that will
-contain your database logic and a reference to a `*bolt.DB` with a initializing
-constructor that takes in a filepath where the database file will be stored.
-Neither Android nor iOS require extra permissions or cleanup from using this method.
-
-```go
-func NewBoltDB(filepath string) *BoltDB {
- db, err := bolt.Open(filepath+"/demo.db", 0600, nil)
- if err != nil {
- log.Fatal(err)
- }
-
- return &BoltDB{db}
-}
-
-type BoltDB struct {
- db *bolt.DB
- ...
-}
-
-func (b *BoltDB) Path() string {
- return b.db.Path()
-}
-
-func (b *BoltDB) Close() {
- b.db.Close()
-}
-```
-
-Database logic should be defined as methods on this wrapper struct.
-
-To initialize this struct from the native language (both platforms now sync
-their local storage to the cloud. These snippets disable that functionality for the
-database file):
-
-#### Android
-
-```java
-String path;
-if (android.os.Build.VERSION.SDK_INT >=android.os.Build.VERSION_CODES.LOLLIPOP){
- path = getNoBackupFilesDir().getAbsolutePath();
-} else{
- path = getFilesDir().getAbsolutePath();
-}
-Boltmobiledemo.BoltDB boltDB = Boltmobiledemo.NewBoltDB(path)
-```
-
-#### iOS
-
-```objc
-- (void)demo {
- NSString* path = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,
- NSUserDomainMask,
- YES) objectAtIndex:0];
- GoBoltmobiledemoBoltDB * demo = GoBoltmobiledemoNewBoltDB(path);
- [self addSkipBackupAttributeToItemAtPath:demo.path];
- //Some DB Logic would go here
- [demo close];
-}
-
-- (BOOL)addSkipBackupAttributeToItemAtPath:(NSString *) filePathString
-{
- NSURL* URL= [NSURL fileURLWithPath: filePathString];
- assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);
-
- NSError *error = nil;
- BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES]
- forKey: NSURLIsExcludedFromBackupKey error: &error];
- if(!success){
- NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);
- }
- return success;
-}
-
-```

-
-## Comparison with other databases
-
-### Postgres, MySQL, & other relational databases
-
-Relational databases structure data into rows and are only accessible through
-the use of SQL. This approach provides flexibility in how you store and query
-your data but also incurs overhead in parsing and planning SQL statements. Bolt
-accesses all data by a byte slice key. This makes Bolt fast to read and write
-data by key but provides no built-in support for joining values together.
-
-Most relational databases (with the exception of SQLite) are standalone servers
-that run separately from your application. This gives your systems
-flexibility to connect multiple application servers to a single database
-server but also adds overhead in serializing and transporting data over the
-network. Bolt runs as a library included in your application so all data access
-has to go through your application's process. This brings data closer to your
-application but limits multi-process access to the data.
-
-
-### LevelDB, RocksDB
-
-LevelDB and its derivatives (RocksDB, HyperLevelDB) are similar to Bolt in that
-they are libraries bundled into the application, however, their underlying
-structure is a log-structured merge-tree (LSM tree). An LSM tree optimizes
-random writes by using a write ahead log and multi-tiered, sorted files called
-SSTables. Bolt uses a B+tree internally and only a single file. Both approaches
-have trade-offs.
-
-If you require a high random write throughput (>10,000 w/sec) or you need to use
-spinning disks then LevelDB could be a good choice. If your application is
-read-heavy or does a lot of range scans then Bolt could be a good choice.
-
-One other important consideration is that LevelDB does not have transactions.
-It supports batch writing of key/values pairs and it supports read snapshots
-but it will not give you the ability to do a compare-and-swap operation safely.
-Bolt supports fully serializable ACID transactions.
-
-
-### LMDB
-
-Bolt was originally a port of LMDB so it is architecturally similar. Both use
-a B+tree, have ACID semantics with fully serializable transactions, and support
-lock-free MVCC using a single writer and multiple readers.
-
-The two projects have somewhat diverged. LMDB heavily focuses on raw performance
-while Bolt has focused on simplicity and ease of use. For example, LMDB allows
-several unsafe actions such as direct writes for the sake of performance. Bolt
-opts to disallow actions which can leave the database in a corrupted state. The
-only exception to this in Bolt is `DB.NoSync`.
-
-There are also a few differences in API. LMDB requires a maximum mmap size when
-opening an `mdb_env` whereas Bolt will handle incremental mmap resizing
-automatically. LMDB overloads the getter and setter functions with multiple
-flags whereas Bolt splits these specialized cases into their own functions.
-
-
-## Caveats & Limitations
-
-It's important to pick the right tool for the job and Bolt is no exception.
-Here are a few things to note when evaluating and using Bolt:
-
-* Bolt is good for read intensive workloads. Sequential write performance is
- also fast but random writes can be slow. You can use `DB.Batch()` or add a
- write-ahead log to help mitigate this issue.
-
-* Bolt uses a B+tree internally so there can be a lot of random page access.
- SSDs provide a significant performance boost over spinning disks.
-
-* Try to avoid long running read transactions. Bolt uses copy-on-write so
- old pages cannot be reclaimed while an old transaction is using them.
-
-* Byte slices returned from Bolt are only valid during a transaction. Once the
- transaction has been committed or rolled back then the memory they point to
- can be reused by a new page or can be unmapped from virtual memory and you'll
- see an `unexpected fault address` panic when accessing it.
-
-* Bolt uses an exclusive write lock on the database file so it cannot be
- shared by multiple processes.
-
-* Be careful when using `Bucket.FillPercent`. Setting a high fill percent for
- buckets that have random inserts will cause your database to have very poor
- page utilization.
-
-* Use larger buckets in general. Smaller buckets causes poor page utilization
- once they become larger than the page size (typically 4KB).
-
-* Bulk loading a lot of random writes into a new bucket can be slow as the
- page will not split until the transaction is committed. Randomly inserting
- more than 100,000 key/value pairs into a single new bucket in a single
- transaction is not advised.
-
-* Bolt uses a memory-mapped file so the underlying operating system handles the
- caching of the data. Typically, the OS will cache as much of the file as it
- can in memory and will release memory as needed to other processes. This means
- that Bolt can show very high memory usage when working with large databases.
- However, this is expected and the OS will release memory as needed. Bolt can
- handle databases much larger than the available physical RAM, provided its
- memory-map fits in the process virtual address space. It may be problematic
- on 32-bits systems.
-
-* The data structures in the Bolt database are memory mapped so the data file
- will be endian specific. This means that you cannot copy a Bolt file from a
- little endian machine to a big endian machine and have it work. For most
- users this is not a concern since most modern CPUs are little endian.
-
-* Because of the way pages are laid out on disk, Bolt cannot truncate data files
- and return free pages back to the disk. Instead, Bolt maintains a free list
- of unused pages within its data file. These free pages can be reused by later
- transactions. This works well for many use cases as databases generally tend
- to grow. However, it's important to note that deleting large chunks of data
- will not allow you to reclaim that space on disk.

-
-## Reading the Source
-
-Bolt is a relatively small code base (<5KLOC) for an embedded, serializable,
-transactional key/value database so it can be a good starting point for people
-interested in how databases work.
-
-The best places to start are the main entry points into Bolt:
-
-- `Open()` - Initializes the reference to the database. It's responsible for
- creating the database if it doesn't exist, obtaining an exclusive lock on the
- file, reading the meta pages, & memory-mapping the file.
-
-- `DB.Begin()` - Starts a read-only or read-write transaction depending on the
- value of the `writable` argument. This requires briefly obtaining the "meta"
- lock to keep track of open transactions. Only one read-write transaction can
- exist at a time so the "rwlock" is acquired during the life of a read-write
- transaction.
-
-- `Bucket.Put()` - Writes a key/value pair into a bucket. After validating the
- arguments, a cursor is used to traverse the B+tree to the page and position
- where they key & value will be written. Once the position is found, the bucket
- materializes the underlying page and the page's parent pages into memory as
- "nodes". These nodes are where mutations occur during read-write transactions.
- These changes get flushed to disk during commit.
-
-- `Bucket.Get()` - Retrieves a key/value pair from a bucket. This uses a cursor
- to move to the page & position of a key/value pair. During a read-only
- transaction, the key and value data is returned as a direct reference to the
- underlying mmap file so there's no allocation overhead. For read-write
- transactions, this data may reference the mmap file or one of the in-memory
- node values.
-
-- `Cursor` - This object is simply for traversing the B+tree of on-disk pages
- or in-memory nodes. It can seek to a specific key, move to the first or last
- value, or it can move forward or backward. The cursor handles the movement up
- and down the B+tree transparently to the end user.
-
-- `Tx.Commit()` - Converts the in-memory dirty nodes and the list of free pages
- into pages to be written to disk. Writing to disk then occurs in two phases.
- First, the dirty pages are written to disk and an `fsync()` occurs. Second, a
- new meta page with an incremented transaction ID is written and another
- `fsync()` occurs. This two phase write ensures that partially written data
- pages are ignored in the event of a crash since the meta page pointing to them
- is never written. Partially written meta pages are invalidated because they
- are written with a checksum.

-optimized for fast read access and does not require recovery in the event of a
-system crash. Transactions which have not finished committing will simply be
-rolled back in the event of a crash.
-
-The design of Bolt is based on Howard Chu's LMDB database project.
-
-Bolt currently works on Windows, Mac OS X, and Linux.
-
-
-Basics
-
-There are only a few types in Bolt: DB, Bucket, Tx, and Cursor. The DB is
-a collection of buckets and is represented by a single file on disk. A bucket is
-a collection of unique keys that are associated with values.
-
-Transactions provide either read-only or read-write access to the database.
-Read-only transactions can retrieve key/value pairs and can use Cursors to
-iterate over the dataset sequentially. Read-write transactions can create and
-delete buckets and can insert and remove keys. Only one read-write transaction
-is allowed at a time.
-
-
-Caveats
-
-The database uses a read-only, memory-mapped data file to ensure that
-applications cannot corrupt the database, however, this means that keys and
-values returned from Bolt cannot be changed. Writing to a read-only byte slice
-will cause Go to panic.
-
-Keys and values retrieved from the database are only valid for the life of
-the transaction. When used outside the transaction, these byte slices can
-point to different data or can point to invalid memory which will cause a panic.

-Package trace implements tracing of requests and long-lived objects.

- tr.SetError()
- }
- }
-
-The /debug/requests HTTP endpoint organizes the traces by family,
-errors, and duration. It also provides histogram of request duration
-for each family.

-A trace.EventLog provides tracing for long-lived objects, such as RPC
-connections.

-# 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}_${GOARCH}.s` implements system
-call dispatch. There are three entry points:
-```
- func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
- func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
- func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
-```
-The first and second are the standard ones; they differ only in how many
-arguments can be passed to the kernel. The third is for low-level use by the
-ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
-let it know that a system call is running.
-
-When porting Go to a new architecture/OS, this file must be implemented for
-each GOOS/GOARCH pair.
-
-### mksysnum
-
-Mksysnum is a Go program located at `${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}_${GOARCH}.go` for the generated
-constants.
-
-Adding new syscall numbers is mostly done by running the build on a sufficiently
-new installation of the target OS (or updating the source checkouts for the
-new build system). However, depending on the OS, you may need to update the
-parsing in mksysnum.
-
-### mksyscall.go
-
-The `syscall.go`, `syscall_${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, and 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}_${GOARCH}.go`.
-
-The hardest part about preparing this file is figuring out which headers to
-include and which symbols need to be `#define`d to get the actual data
-structures that pass through to the kernel system calls. Some C libraries
-preset alternate versions for binary compatibility and translate them on the
-way in and out of system calls, but there is almost always a `#define` that can
-get the real ones.
-See `types_darwin.go` and `linux/types.go` for examples.
-
-To add a new type, add in the necessary include statement at the top of the
-file (if it is not already there) and add in a type alias line. Note that if
-your type is significantly different on different architectures, you may need
-some `#if/#elif` macros in your include statements.
-
-### mkerrors.sh
-
-This script is used to generate the system's various constants. This doesn't
-just include the error numbers and error strings, but also the signal numbers
-and a wide variety of miscellaneous constants. The constants come from the list
-of include files in the `includes_${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.
-
-### internal/mkmerge
-
-This program is used to extract duplicate const, func, and type declarations
-from the generated architecture-specific files listed below, and merge these
-into a common file for each OS.
-
-The merge is performed in the following steps:
-1. Construct the set of common code that is idential in all architecture-specific files.
-2. Write this common code to the merged file.
-3. Remove the common code from all architecture-specific files.
-
-
-## Generated files
-
-### `zerrors_${GOOS}_${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).
