# 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 doesn’t 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).
|
||||
|
||||

|
||||
|

"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain

separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.

2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,

||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|

|
||||
|
||||
## 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()`
|
||||
|
||||
## 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{}`

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。
|
||||

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()`
|
||||
|
||||
## 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。
