# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, religion, or sexual identity
and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the
overall community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or
advances of any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email
address, without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
wudi.daniel@bytedance.com.
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series
of actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or
permanent ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within
the community.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage],
version 2.0, available at
https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.
Community Impact Guidelines were inspired by [Mozilla's code of conduct
enforcement ladder](https://github.com/mozilla/diversity).

# How to Contribute
## Your First Pull Request
We use GitHub for our codebase. You can start by reading [How To Pull Request](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests).
## Without Semantic Versioning
We keep the stable code in branch `main` like `golang.org/x`. Development base on branch `develop`. We promise the **Forward Compatibility** by adding new package directory with suffix `v2/v3` when code has break changes.
## Branch Organization
We use [git-flow](https://nvie.com/posts/a-successful-git-branching-model/) as our branch organization, as known as [FDD](https://en.wikipedia.org/wiki/Feature-driven_development)
## Bugs
### 1. How to Find Known Issues
We are using [Github Issues](https://github.com/bytedance/sonic/issues) for our public bugs. We keep a close eye on this and try to make it clear when we have an internal fix in progress. Before filing a new task, try to make sure your problem doesnt already exist.
### 2. Reporting New Issues
Providing a reduced test code is a recommended way for reporting issues. Then can be placed in:
- Just in issues
- [Golang Playground](https://play.golang.org/)
### 3. Security Bugs
Please do not report the safe disclosure of bugs to public issues. Contact us by [Support Email](mailto:sonic@bytedance.com)
## How to Get in Touch
- [Email](mailto:wudi.daniel@bytedance.com)
## Submit a Pull Request
Before you submit your Pull Request (PR) consider the following guidelines:
1. Search [GitHub](https://github.com/bytedance/sonic/pulls) for an open or closed PR that relates to your submission. You don't want to duplicate existing efforts.
2. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add. Discussing the design upfront helps to ensure that we're ready to accept your work.
3. [Fork](https://docs.github.com/en/github/getting-started-with-github/fork-a-repo) the bytedance/sonic repo.
4. In your forked repository, make your changes in a new git branch:
```
git checkout -b bugfix/security_bug develop
```
5. Create your patch, including appropriate test cases.
6. Follow our [Style Guides](#code-style-guides).
7. Commit your changes using a descriptive commit message that follows [AngularJS Git Commit Message Conventions](https://docs.google.com/document/d/1QrDFcIiPjSLDn3EL15IJygNPiHORgU1_OOAqWjiDU5Y/edit).
Adherence to these conventions is necessary because release notes will be automatically generated from these messages.
8. Push your branch to GitHub:
```
git push origin bugfix/security_bug
```
9. In GitHub, send a pull request to `sonic:main`
Note: you must use one of `optimize/feature/bugfix/doc/ci/test/refactor` following a slash(`/`) as the branch prefix.
Your pr title and commit message should follow https://www.conventionalcommits.org/.
## Contribution Prerequisites
- Our development environment keeps up with [Go Official](https://golang.org/project/).
- You need fully checking with lint tools before submit your pull request. [gofmt](https://golang.org/pkg/cmd/gofmt/) & [golangci-lint](https://github.com/golangci/golangci-lint)
- You are familiar with [Github](https://github.com)
- Maybe you need familiar with [Actions](https://github.com/features/actions)(our default workflow tool).
## Code Style Guides
See [Go Code Review Comments](https://github.com/golang/go/wiki/CodeReviewComments).
Good resources:
- [Effective Go](https://golang.org/doc/effective_go)
- [Pingcap General advice](https://pingcap.github.io/style-guide/general.html)

## How it works
See [INTRODUCTION.md](./docs/INTRODUCTION.md).
## Usage
### Marshal/Unmarshal
Default behaviors are mostly consistent with `encoding/json`, except HTML escaping form (see [Escape HTML](https://github.com/bytedance/sonic/blob/main/README.md#escape-html)) and `SortKeys` feature (optional support see [Sort Keys](https://github.com/bytedance/sonic/blob/main/README.md#sort-keys)) that is **NOT** in conformity to [RFC8259](https://datatracker.ietf.org/doc/html/rfc8259).
```go
import "github.com/bytedance/sonic"
var data YourSchema
// Marshal
output, err := sonic.Marshal(&data)
// Unmarshal
err := sonic.Unmarshal(output, &data)
```
### Streaming IO
Sonic supports decoding json from `io.Reader` or encoding objects into `io.`Writer`, aims at handling multiple values as well as reducing memory consumption.
- encoder
```go
var o1 = map[string]interface{}{
"a": "b",
}
var o2 = 1
var w = bytes.NewBuffer(nil)
var enc = sonic.ConfigDefault.NewEncoder(w)
enc.Encode(o1)
enc.Encode(o2)
fmt.Println(w.String())
// Output:
// {"a":"b"}
// 1
```
- decoder
```go
var o = map[string]interface{}{}
var r = strings.NewReader(`{"a":"b"}{"1":"2"}`)
var dec = sonic.ConfigDefault.NewDecoder(r)
dec.Decode(&o)
dec.Decode(&o)
fmt.Printf("%+v", o)
// Output:
// map[1:2 a:b]
```
### Use Number/Use Int64
```go
import "github.com/bytedance/sonic/decoder"
var input = `1`
var data interface{}
// default float64
dc := decoder.NewDecoder(input)
dc.Decode(&data) // data == float64(1)
// use json.Number
dc = decoder.NewDecoder(input)
dc.UseNumber()
dc.Decode(&data) // data == json.Number("1")
// use int64
dc = decoder.NewDecoder(input)
dc.UseInt64()
dc.Decode(&data) // data == int64(1)
root, err := sonic.GetFromString(input)
// Get json.Number
jn := root.Number()
jm := root.InterfaceUseNumber().(json.Number) // jn == jm
// Get float64
fn := root.Float64()
fm := root.Interface().(float64) // jn == jm
```
### Sort Keys
On account of the performance loss from sorting (roughly 10%), sonic doesn't enable this feature by default. If your component depends on it to work (like [zstd](https://github.com/facebook/zstd)), Use it like this:
```go
import "github.com/bytedance/sonic"
import "github.com/bytedance/sonic/encoder"
// Binding map only
m := map[string]interface{}{}
v, err := encoder.Encode(m, encoder.SortMapKeys)
// Or ast.Node.SortKeys() before marshal
var root := sonic.Get(JSON)
err := root.SortKeys()
```
### Escape HTML
On account of the performance loss (roughly 15%), sonic doesn't enable this feature by default. You can use `encoder.EscapeHTML` option to open this feature (align with `encoding/json.HTMLEscape`).
```go
import "github.com/bytedance/sonic"
v := map[string]string{"&&":"<>"}
ret, err := Encode(v, EscapeHTML) // ret == `{"\u0026\u0026":{"X":"\u003c\u003e"}}`
```
### Compact Format
Sonic encodes primitive objects (struct/map...) as compact-format JSON by default, except marshaling `json.RawMessage` or `json.Marshaler`: sonic ensures validating their output JSON but **DONOT** compacting them for performance concerns. We provide the option `encoder.CompactMarshaler` to add compacting process.
### Print Error
If there invalid syntax in input JSON, sonic will return `decoder.SyntaxError`, which supports pretty-printing of error position
```go
import "github.com/bytedance/sonic"
import "github.com/bytedance/sonic/decoder"
var data interface{}
err := sonic.UnmarshalString("[[[}]]", &data)
if err != nil {
/* One line by default */
println(e.Error()) // "Syntax error at index 3: invalid char\n\n\t[[[}]]\n\t...^..\n"
/* Pretty print */
if e, ok := err.(decoder.SyntaxError); ok {
/*Syntax error at index 3: invalid char
[[[}]]
...^..
*/
print(e.Description())
} else if me, ok := err.(*decoder.MismatchTypeError); ok {
// decoder.MismatchTypeError is new to Sonic v1.6.0
print(me.Description())
}
}
```
#### Mismatched Types [Sonic v1.6.0]
If there a **mismatch-typed** value for a given key, sonic will report `decoder.MismatchTypeError` (if there are many, report the last one), but still skip wrong the value and keep decoding next JSON.
```go
import "github.com/bytedance/sonic"
import "github.com/bytedance/sonic/decoder"
var data = struct{
A int
B int
}{}
err := UnmarshalString(`{"A":"1","B":1}`, &data)
println(err.Error()) // Mismatch type int with value string "at index 5: mismatched type with value\n\n\t{\"A\":\"1\",\"B\":1}\n\t.....^.........\n"
fmt.Printf("%+v", data) // {A:0 B:1}
```
### Ast.Node
Sonic/ast.Node is a completely self-contained AST for JSON. It implements serialization and deserialization both and provides robust APIs for obtaining and modification of generic data.
#### Get/Index
Search partial JSON by given paths, which must be non-negative integer or string, or nil
```go
import "github.com/bytedance/sonic"
input := []byte(`{"key1":[{},{"key2":{"key3":[1,2,3]}}]}`)
// no path, returns entire json
root, err := sonic.Get(input)
raw := root.Raw() // == string(input)
// multiple paths
root, err := sonic.Get(input, "key1", 1, "key2")
sub := root.Get("key3").Index(2).Int64() // == 3
```
**Tip**: since `Index()` uses offset to locate data, which is much faster than scanning like `Get()`, we suggest you use it as much as possible. And sonic also provides another API `IndexOrGet()` to underlying use offset as well as ensure the key is matched.
#### Set/Unset
Modify the json content by Set()/Unset()
```go
import "github.com/bytedance/sonic"
// Set
exist, err := root.Set("key4", NewBool(true)) // exist == false
alias1 := root.Get("key4")
println(alias1.Valid()) // true
alias2 := root.Index(1)
println(alias1 == alias2) // true
// Unset
exist, err := root.UnsetByIndex(1) // exist == true
println(root.Get("key4").Check()) // "value not exist"
```
#### Serialize
To encode `ast.Node` as json, use `MarshalJson()` or `json.Marshal()` (MUST pass the node's pointer)
```go
import (
"encoding/json"
"github.com/bytedance/sonic"
)
buf, err := root.MarshalJson()
println(string(buf)) // {"key1":[{},{"key2":{"key3":[1,2,3]}}]}
exp, err := json.Marshal(&root) // WARN: use pointer
println(string(buf) == string(exp)) // true
```
#### APIs
- validation: `Check()`, `Error()`, `Valid()`, `Exist()`
- searching: `Index()`, `Get()`, `IndexPair()`, `IndexOrGet()`, `GetByPath()`
- go-type casting: `Int64()`, `Float64()`, `String()`, `Number()`, `Bool()`, `Map[UseNumber|UseNode]()`, `Array[UseNumber|UseNode]()`, `Interface[UseNumber|UseNode]()`
- go-type packing: `NewRaw()`, `NewNumber()`, `NewNull()`, `NewBool()`, `NewString()`, `NewObject()`, `NewArray()`
- iteration: `Values()`, `Properties()`, `ForEach()`, `SortKeys()`
- modification: `Set()`, `SetByIndex()`, `Add()`
### Ast.Visitor
Sonic provides an advanced API for fully parsing JSON into non-standard types (neither `struct` not `map[string]interface{}`) without using any intermediate representation (`ast.Node` or `interface{}`). For example, you might have the following types which are like `interface{}` but actually not `interface{}`:
```go
type UserNode interface {}
// the following types implement the UserNode interface.
type (
UserNull struct{}
UserBool struct{ Value bool }
UserInt64 struct{ Value int64 }
UserFloat64 struct{ Value float64 }
UserString struct{ Value string }
UserObject struct{ Value map[string]UserNode }
UserArray struct{ Value []UserNode }
)
```
Sonic provides the following API to return **the preorder traversal of a JSON AST**. The `ast.Visitor` is a SAX style interface which is used in some C++ JSON library. You should implement `ast.Visitor` by yourself and pass it to `ast.Preorder()` method. In your visitor you can make your custom types to represent JSON values. There may be an O(n) space container (such as stack) in your visitor to record the object / array hierarchy.
```go
func Preorder(str string, visitor Visitor, opts *VisitorOptions) error
type Visitor interface {
OnNull() error
OnBool(v bool) error
OnString(v string) error
OnInt64(v int64, n json.Number) error
OnFloat64(v float64, n json.Number) error
OnObjectBegin(capacity int) error
OnObjectKey(key string) error
OnObjectEnd() error
OnArrayBegin(capacity int) error
OnArrayEnd() error
}
```
See [ast/visitor.go](https://github.com/bytedance/sonic/blob/main/ast/visitor.go) for detailed usage. We also implement a demo visitor for `UserNode` in [ast/visitor_test.go](https://github.com/bytedance/sonic/blob/main/ast/visitor_test.go).
## Compatibility
Sonic **DOES NOT** ensure to support all environments, due to the difficulty of developing high-performance codes. For developers who use sonic to build their applications in different environments, we have the following suggestions:
- Developing on **Mac M1**: Make sure you have Rosetta 2 installed on your machine, and set `GOARCH=amd64` when building your application. Rosetta 2 can automatically translate x86 binaries to arm64 binaries and run x86 applications on Mac M1.
- Developing on **Linux arm64**: You can install qemu and use the `qemu-x86_64 -cpu max` command to convert x86 binaries to amr64 binaries for applications built with sonic. The qemu can achieve a similar transfer effect to Rosetta 2 on Mac M1.
For developers who want to use sonic on Linux arm64 without qemu, or those who want to handle JSON strictly consistent with `encoding/json`, we provide some compatible APIs as `sonic.API`
- `ConfigDefault`: the sonic's default config (`EscapeHTML=false`,`SortKeys=false`...) to run on sonic-supporting environment. It will fall back to `encoding/json` with the corresponding config, and some options like `SortKeys=false` will be invalid.
- `ConfigStd`: the std-compatible config (`EscapeHTML=true`,`SortKeys=true`...) to run on sonic-supporting environment. It will fall back to `encoding/json`.
- `ConfigFastest`: the fastest config (`NoQuoteTextMarshaler=true`) to run on sonic-supporting environment. It will fall back to `encoding/json` with the corresponding config, and some options will be invalid.
## Tips
### Pretouch
Since Sonic uses [golang-asm](https://github.com/twitchyliquid64/golang-asm) as a JIT assembler, which is NOT very suitable for runtime compiling, first-hit running of a huge schema may cause request-timeout or even process-OOM. For better stability, we advise **using `Pretouch()` for huge-schema or compact-memory applications** before `Marshal()/Unmarshal()`.
```go
import (
"reflect"
"github.com/bytedance/sonic"
"github.com/bytedance/sonic/option"
)
func init() {
var v HugeStruct
// For most large types (nesting depth <= option.DefaultMaxInlineDepth)
err := sonic.Pretouch(reflect.TypeOf(v))
// with more CompileOption...
err := sonic.Pretouch(reflect.TypeOf(v),
// If the type is too deep nesting (nesting depth > option.DefaultMaxInlineDepth),
// you can set compile recursive loops in Pretouch for better stability in JIT.
option.WithCompileRecursiveDepth(loop),
// For a large nested struct, try to set a smaller depth to reduce compiling time.
option.WithCompileMaxInlineDepth(depth),
)
}
```
### Copy string
When decoding **string values without any escaped characters**, sonic references them from the origin JSON buffer instead of mallocing a new buffer to copy. This helps a lot for CPU performance but may leave the whole JSON buffer in memory as long as the decoded objects are being used. In practice, we found the extra memory introduced by referring JSON buffer is usually 20% ~ 80% of decoded objects. Once an application holds these objects for a long time (for example, cache the decoded objects for reusing), its in-use memory on the server may go up. We provide the option `decoder.CopyString()` for users to choose not to reference the JSON buffer, which may cause a decline in CPU performance to some degree.
### Pass string or []byte?
For alignment to `encoding/json`, we provide API to pass `[]byte` as an argument, but the string-to-bytes copy is conducted at the same time considering safety, which may lose performance when the origin JSON is huge. Therefore, you can use `UnmarshalString()` and `GetFromString()` to pass a string, as long as your origin data is a string or **nocopy-cast** is safe for your []byte. We also provide API `MarshalString()` for convenient **nocopy-cast** of encoded JSON []byte, which is safe since sonic's output bytes is always duplicated and unique.
### Accelerate `encoding.TextMarshaler`
To ensure data security, sonic.Encoder quotes and escapes string values from `encoding.TextMarshaler` interfaces by default, which may degrade performance much if most of your data is in form of them. We provide `encoder.NoQuoteTextMarshaler` to skip these operations, which means you **MUST** ensure their output string escaped and quoted following [RFC8259](https://datatracker.ietf.org/doc/html/rfc8259).
### Better performance for generic data
In **fully-parsed** scenario, `Unmarshal()` performs better than `Get()`+`Node.Interface()`. But if you only have a part of the schema for specific json, you can combine `Get()` and `Unmarshal()` together:
```go
import "github.com/bytedance/sonic"
node, err := sonic.GetFromString(_TwitterJson, "statuses", 3, "user")
var user User // your partial schema...
err = sonic.UnmarshalString(node.Raw(), &user)
```
Even if you don't have any schema, use `ast.Node` as the container of generic values instead of `map` or `interface`:
```go
import "github.com/bytedance/sonic"
root, err := sonic.GetFromString(_TwitterJson)
user := root.GetByPath("statuses", 3, "user") // === root.Get("status").Index(3).Get("user")
err = user.Check()
// err = user.LoadAll() // only call this when you want to use 'user' concurrently...
go someFunc(user)
```
Why? Because `ast.Node` stores its children using `array`:
- `Array`'s performance is **much better** than `Map` when Inserting (Deserialize) and Scanning (Serialize) data;
- **Hashing** (`map[x]`) is not as efficient as **Indexing** (`array[x]`), which `ast.Node` can conduct on **both array and object**;
- Using `Interface()`/`Map()` means Sonic must parse all the underlying values, while `ast.Node` can parse them **on demand**.
**CAUTION:** `ast.Node` **DOESN'T** ensure concurrent security directly, due to its **lazy-load** design. However, you can call `Node.Load()`/`Node.LoadAll()` to achieve that, which may bring performance reduction while it still works faster than converting to `map` or `interface{}`
### Ast.Node or Ast.Visitor?
For generic data, `ast.Node` should be enough for your needs in most cases.
However, `ast.Node` is designed for partially processing JSON string. It has some special designs such as lazy-load which might not be suitable for directly parsing the whole JSON string like `Unmarshal()`. Although `ast.Node` is better then `map` or `interface{}`, it's also a kind of intermediate representation after all if your final types are customized and you have to convert the above types to your custom types after parsing.
For better performance, in previous case the `ast.Visitor` will be the better choice. It performs JSON decoding like `Unmarshal()` and you can directly use your final types to represents a JSON AST without any intermediate representations.
But `ast.Visitor` is not a very handy API. You might need to write a lot of code to implement your visitor and carefully maintain the tree hierarchy during decoding. Please read the comments in [ast/visitor.go](https://github.com/bytedance/sonic/blob/main/ast/visitor.go) carefully if you decide to use this API.

## 工作原理
请参阅 [INTRODUCTION_ZH_CN.md](./docs/INTRODUCTION_ZH_CN.md).
## 使用方式
### 序列化/反序列化
默认的行为基本上与 `encoding/json` 相一致,除了 HTML 转义形式(参见 [Escape HTML](https://github.com/bytedance/sonic/blob/main/README.md#escape-html)) 和 `SortKeys` 功能(参见 [Sort Keys](https://github.com/bytedance/sonic/blob/main/README.md#sort-keys)**没有**遵循 [RFC8259](https://datatracker.ietf.org/doc/html/rfc8259) 。
```go
import "github.com/bytedance/sonic"
var data YourSchema
// Marshal
output, err := sonic.Marshal(&data)
// Unmarshal
err := sonic.Unmarshal(output, &data)
```
### 流式输入输出
Sonic 支持解码 `io.Reader` 中输入的 json或将对象编码为 json 后输出至 `io.Writer`,以处理多个值并减少内存消耗。
- 编码器
```go
var o1 = map[string]interface{}{
"a": "b",
}
var o2 = 1
var w = bytes.NewBuffer(nil)
var enc = sonic.ConfigDefault.NewEncoder(w)
enc.Encode(o1)
enc.Encode(o2)
fmt.Println(w.String())
// Output:
// {"a":"b"}
// 1
```
- 解码器
```go
var o = map[string]interface{}{}
var r = strings.NewReader(`{"a":"b"}{"1":"2"}`)
var dec = sonic.ConfigDefault.NewDecoder(r)
dec.Decode(&o)
dec.Decode(&o)
fmt.Printf("%+v", o)
// Output:
// map[1:2 a:b]
```
### 使用 `Number` / `int64`
```go
import "github.com/bytedance/sonic/decoder"
var input = `1`
var data interface{}
// default float64
dc := decoder.NewDecoder(input)
dc.Decode(&data) // data == float64(1)
// use json.Number
dc = decoder.NewDecoder(input)
dc.UseNumber()
dc.Decode(&data) // data == json.Number("1")
// use int64
dc = decoder.NewDecoder(input)
dc.UseInt64()
dc.Decode(&data) // data == int64(1)
root, err := sonic.GetFromString(input)
// Get json.Number
jn := root.Number()
jm := root.InterfaceUseNumber().(json.Number) // jn == jm
// Get float64
fn := root.Float64()
fm := root.Interface().(float64) // jn == jm
```
### 对键排序
考虑到排序带来的性能损失(约 10% sonic 默认不会启用这个功能。如果你的组件依赖这个行为(如 [zstd](https://github.com/facebook/zstd)) ,可以仿照下面的例子:
```go
import "github.com/bytedance/sonic"
import "github.com/bytedance/sonic/encoder"
// Binding map only
m := map[string]interface{}{}
v, err := encoder.Encode(m, encoder.SortMapKeys)
// Or ast.Node.SortKeys() before marshal
var root := sonic.Get(JSON)
err := root.SortKeys()
```
### HTML 转义
考虑到性能损失约15% sonic 默认不会启用这个功能。你可以使用 `encoder.EscapeHTML` 选项来开启(与 `encoding/json.HTMLEscape` 行为一致)。
```go
import "github.com/bytedance/sonic"
v := map[string]string{"&&":"<>"}
ret, err := Encode(v, EscapeHTML) // ret == `{"\u0026\u0026":{"X":"\u003c\u003e"}}`
```
### 紧凑格式
Sonic 默认将基本类型( `struct` `map` 等)编码为紧凑格式的 JSON ,除非使用 `json.RawMessage` or `json.Marshaler` 进行编码: sonic 确保输出的 JSON 合法,但出于性能考虑,**不会**加工成紧凑格式。我们提供选项 `encoder.CompactMarshaler` 来添加此过程,
### 打印错误
如果输入的 JSON 存在无效的语法sonic 将返回 `decoder.SyntaxError`,该错误支持错误位置的美化输出。
```go
import "github.com/bytedance/sonic"
import "github.com/bytedance/sonic/decoder"
var data interface{}
err := sonic.UnmarshalString("[[[}]]", &data)
if err != nil {
/* One line by default */
println(e.Error()) // "Syntax error at index 3: invalid char\n\n\t[[[}]]\n\t...^..\n"
/* Pretty print */
if e, ok := err.(decoder.SyntaxError); ok {
/*Syntax error at index 3: invalid char
[[[}]]
...^..
*/
print(e.Description())
} else if me, ok := err.(*decoder.MismatchTypeError); ok {
// decoder.MismatchTypeError is new to Sonic v1.6.0
print(me.Description())
}
}
```
#### 类型不匹配 [Sonic v1.6.0]
如果给定键中存在**类型不匹配**的值, sonic 会抛出 `decoder.MismatchTypeError` (如果有多个,只会报告最后一个),但仍会跳过错误的值并解码下一个 JSON 。
```go
import "github.com/bytedance/sonic"
import "github.com/bytedance/sonic/decoder"
var data = struct{
A int
B int
}{}
err := UnmarshalString(`{"A":"1","B":1}`, &data)
println(err.Error()) // Mismatch type int with value string "at index 5: mismatched type with value\n\n\t{\"A\":\"1\",\"B\":1}\n\t.....^.........\n"
fmt.Printf("%+v", data) // {A:0 B:1}
```
### `Ast.Node`
Sonic/ast.Node 是完全独立的 JSON 抽象语法树库。它实现了序列化和反序列化,并提供了获取和修改通用数据的鲁棒的 API。
#### 查找/索引
通过给定的路径搜索 JSON 片段,路径必须为非负整数,字符串或 `nil` 。
```go
import "github.com/bytedance/sonic"
input := []byte(`{"key1":[{},{"key2":{"key3":[1,2,3]}}]}`)
// no path, returns entire json
root, err := sonic.Get(input)
raw := root.Raw() // == string(input)
// multiple paths
root, err := sonic.Get(input, "key1", 1, "key2")
sub := root.Get("key3").Index(2).Int64() // == 3
```
**注意**:由于 `Index()` 使用偏移量来定位数据,比使用扫描的 `Get()` 要快的多,建议尽可能的使用 `Index` 。 Sonic 也提供了另一个 API `IndexOrGet()` ,以偏移量为基础并且也确保键的匹配。
#### 修改
使用 ` Set()` / `Unset()` 修改 json 的内容
```go
import "github.com/bytedance/sonic"
// Set
exist, err := root.Set("key4", NewBool(true)) // exist == false
alias1 := root.Get("key4")
println(alias1.Valid()) // true
alias2 := root.Index(1)
println(alias1 == alias2) // true
// Unset
exist, err := root.UnsetByIndex(1) // exist == true
println(root.Get("key4").Check()) // "value not exist"
```
#### 序列化
要将 `ast.Node` 编码为 json ,使用 `MarshalJson()` 或者 `json.Marshal()` (必须传递指向节点的指针)
```go
import (
"encoding/json"
"github.com/bytedance/sonic"
)
buf, err := root.MarshalJson()
println(string(buf)) // {"key1":[{},{"key2":{"key3":[1,2,3]}}]}
exp, err := json.Marshal(&root) // WARN: use pointer
println(string(buf) == string(exp)) // true
```
#### APIs
- 合法性检查: `Check()`, `Error()`, `Valid()`, `Exist()`
- 索引: `Index()`, `Get()`, `IndexPair()`, `IndexOrGet()`, `GetByPath()`
- 转换至 go 内置类型: `Int64()`, `Float64()`, `String()`, `Number()`, `Bool()`, `Map[UseNumber|UseNode]()`, `Array[UseNumber|UseNode]()`, `Interface[UseNumber|UseNode]()`
- go 类型打包: `NewRaw()`, `NewNumber()`, `NewNull()`, `NewBool()`, `NewString()`, `NewObject()`, `NewArray()`
- 迭代: `Values()`, `Properties()`, `ForEach()`, `SortKeys()`
- 修改: `Set()`, `SetByIndex()`, `Add()`
### `Ast.Visitor`
Sonic 提供了一个高级的 API 用于直接全量解析 JSON 到非标准容器里 (既不是 `struct` 也不是 `map[string]interface{}`) 且不需要借助任何中间表示 (`ast.Node` 或 `interface{}`)。举个例子,你可能定义了下述的类型,它们看起来像 `interface{}`,但实际上并不是:
```go
type UserNode interface {}
// the following types implement the UserNode interface.
type (
UserNull struct{}
UserBool struct{ Value bool }
UserInt64 struct{ Value int64 }
UserFloat64 struct{ Value float64 }
UserString struct{ Value string }
UserObject struct{ Value map[string]UserNode }
UserArray struct{ Value []UserNode }
)
```
Sonic 提供了下述的 API 来返回 **“对 JSON AST 的前序遍历”**。`ast.Visitor` 是一个 SAX 风格的接口,这在某些 C++ 的 JSON 解析库中被使用到。你需要自己实现一个 `ast.Visitor`,将它传递给 `ast.Preorder()` 方法。在你的实现中你可以使用自定义的类型来表示 JSON 的值。在你的 `ast.Visitor` 中,可能需要有一个 O(n) 空间复杂度的容器(比如说栈)来记录 object / array 的层级。
```go
func Preorder(str string, visitor Visitor, opts *VisitorOptions) error
type Visitor interface {
OnNull() error
OnBool(v bool) error
OnString(v string) error
OnInt64(v int64, n json.Number) error
OnFloat64(v float64, n json.Number) error
OnObjectBegin(capacity int) error
OnObjectKey(key string) error
OnObjectEnd() error
OnArrayBegin(capacity int) error
OnArrayEnd() error
}
```
详细用法参看 [ast/visitor.go](https://github.com/bytedance/sonic/blob/main/ast/visitor.go),我们还为 `UserNode` 实现了一个示例 `ast.Visitor`,你可以在 [ast/visitor_test.go](https://github.com/bytedance/sonic/blob/main/ast/visitor_test.go) 中找到它。
## 兼容性
由于开发高性能代码的困难性, Sonic **不**保证对所有环境的支持。对于在不同环境中使用 Sonic 构建应用程序的开发者,我们有以下建议:
- 在 **Mac M1** 上开发:确保在您的计算机上安装了 Rosetta 2并在构建时设置 `GOARCH=amd64` 。 Rosetta 2 可以自动将 x86 二进制文件转换为 arm64 二进制文件,并在 Mac M1 上运行 x86 应用程序。
- 在 **Linux arm64** 上开发:您可以安装 qemu 并使用 `qemu-x86_64 -cpu max` 命令来将 x86 二进制文件转换为 arm64 二进制文件。qemu可以实现与Mac M1上的Rosetta 2类似的转换效果。
对于希望在不使用 qemu 下使用 sonic 的开发者,或者希望处理 JSON 时与 `encoding/JSON` 严格保持一致的开发者,我们在 `sonic.API` 中提供了一些兼容性 API
- `ConfigDefault`: 在支持 sonic 的环境下 sonic 的默认配置(`EscapeHTML=false``SortKeys=false`等)。行为与具有相应配置的 `encoding/json` 一致,一些选项,如 `SortKeys=false` 将无效。
- `ConfigStd`: 在支持 sonic 的环境下与标准库兼容的配置(`EscapeHTML=true``SortKeys=true`等)。行为与 `encoding/json` 一致。
- `ConfigFastest`: 在支持 sonic 的环境下运行最快的配置(`NoQuoteTextMarshaler=true`)。行为与具有相应配置的 `encoding/json` 一致,某些选项将无效。
## 注意事项
### 预热
由于 Sonic 使用 [golang-asm](https://github.com/twitchyliquid64/golang-asm) 作为 JIT 汇编器,这个库并不适用于运行时编译,第一次运行一个大型模式可能会导致请求超时甚至进程内存溢出。为了更好地稳定性,我们建议在运行大型模式或在内存有限的应用中,在使用 `Marshal()/Unmarshal()` 前运行 `Pretouch()`。
```go
import (
"reflect"
"github.com/bytedance/sonic"
"github.com/bytedance/sonic/option"
)
func init() {
var v HugeStruct
// For most large types (nesting depth <= option.DefaultMaxInlineDepth)
err := sonic.Pretouch(reflect.TypeOf(v))
// with more CompileOption...
err := sonic.Pretouch(reflect.TypeOf(v),
// If the type is too deep nesting (nesting depth > option.DefaultMaxInlineDepth),
// you can set compile recursive loops in Pretouch for better stability in JIT.
option.WithCompileRecursiveDepth(loop),
// For a large nested struct, try to set a smaller depth to reduce compiling time.
option.WithCompileMaxInlineDepth(depth),
)
}
```
### 拷贝字符串
当解码 **没有转义字符的字符串**时, sonic 会从原始的 JSON 缓冲区内引用而不是复制到新的一个缓冲区中。这对 CPU 的性能方面很有帮助,但是可能因此在解码后对象仍在使用的时候将整个 JSON 缓冲区保留在内存中。实践中我们发现,通过引用 JSON 缓冲区引入的额外内存通常是解码后对象的 20% 至 80% ,一旦应用长期保留这些对象(如缓存以备重用),服务器所使用的内存可能会增加。我们提供了选项 `decoder.CopyString()` 供用户选择,不引用 JSON 缓冲区。这可能在一定程度上降低 CPU 性能。
### 传递字符串还是字节数组?
为了和 `encoding/json` 保持一致,我们提供了传递 `[]byte` 作为参数的 API ,但考虑到安全性,字符串到字节的复制是同时进行的,这在原始 JSON 非常大时可能会导致性能损失。因此,你可以使用 `UnmarshalString()` 和 `GetFromString()` 来传递字符串,只要你的原始数据是字符串,或**零拷贝类型转换**对于你的字节数组是安全的。我们也提供了 `MarshalString()` 的 API ,以便对编码的 JSON 字节数组进行**零拷贝类型转换**,因为 sonic 输出的字节始终是重复并且唯一的,所以这样是安全的。
### 加速 `encoding.TextMarshaler`
为了保证数据安全性, `sonic.Encoder` 默认会对来自 `encoding.TextMarshaler` 接口的字符串进行引用和转义,如果大部分数据都是这种形式那可能会导致很大的性能损失。我们提供了 `encoder.NoQuoteTextMarshaler` 选项来跳过这些操作,但你**必须**保证他们的输出字符串依照 [RFC8259](https://datatracker.ietf.org/doc/html/rfc8259) 进行了转义和引用。
### 泛型的性能优化
在 **完全解析**的场景下, `Unmarshal()` 表现得比 `Get()`+`Node.Interface()` 更好。但是如果你只有特定 JSON 的部分模式,你可以将 `Get()` 和 `Unmarshal()` 结合使用:
```go
import "github.com/bytedance/sonic"
node, err := sonic.GetFromString(_TwitterJson, "statuses", 3, "user")
var user User // your partial schema...
err = sonic.UnmarshalString(node.Raw(), &user)
```
甚至如果你没有任何模式,可以用 `ast.Node` 代替 `map` 或 `interface` 作为泛型的容器:
```go
import "github.com/bytedance/sonic"
root, err := sonic.GetFromString(_TwitterJson)
user := root.GetByPath("statuses", 3, "user") // === root.Get("status").Index(3).Get("user")
err = user.Check()
// err = user.LoadAll() // only call this when you want to use 'user' concurrently...
go someFunc(user)
```
为什么?因为 `ast.Node` 使用 `array` 来存储其子节点:
- 在插入(反序列化)和扫描(序列化)数据时,`Array` 的性能比 `Map` **好得多**
- **哈希**`map[x]`)的效率不如**索引**`array[x]`)高效,而 `ast.Node` 可以在数组和对象上使用索引;
- 使用 `Interface()` / `Map()` 意味着 sonic 必须解析所有的底层值,而 `ast.Node` 可以**按需解析**它们。
**注意**:由于 `ast.Node` 的惰性加载设计,其**不能**直接保证并发安全性,但你可以调用 `Node.Load()` / `Node.LoadAll()` 来实现并发安全。尽管可能会带来性能损失,但仍比转换成 `map` 或 `interface{}` 更为高效。
### 使用 `ast.Node` 还是 `ast.Visitor`
对于泛型数据的解析,`ast.Node` 在大多数场景上应该能够满足你的需求。
然而,`ast.Node` 是一种针对部分解析 JSON 而设计的泛型容器,它包含一些特殊设计,比如惰性加载,如果你希望像 `Unmarshal()` 那样直接解析整个 JSON这些设计可能并不合适。尽管 `ast.Node` 相较于 `map` 或 `interface{}` 来说是更好的一种泛型容器,但它毕竟也是一种中间表示,如果你的最终类型是自定义的,你还得在解析完成后将上述类型转化成你自定义的类型。
在上述场景中,如果想要有更极致的性能,`ast.Visitor` 会是更好的选择。它采用和 `Unmarshal()` 类似的形式解析 JSON并且你可以直接使用你的最终类型去表示 JSON AST而不需要经过额外的任何中间表示。
但是,`ast.Visitor` 并不是一个很易用的 API。你可能需要写大量的代码去实现自己的 `ast.Visitor`,并且需要在解析过程中仔细维护树的层级。如果你决定要使用这个 API请先仔细阅读 [ast/visitor.go](https://github.com/bytedance/sonic/blob/main/ast/visitor.go) 中的注释。
