# Changelog
This file documents all notable changes made to this project since the initial fork
from https://github.com/syndtr/gocapability/commit/42c35b4376354fd5.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [0.4.0] - 2024-11-11
### Added
* New separate API for ambient ([GetAmbient], [SetAmbient], [ResetAmbient])
and bound ([GetBound], [DropBound]) capabilities, modelled after libcap. (#176)
### Fixed
* [Apply] now returns an error if called for non-zero `pid`. Before this change,
it could silently change some capabilities of the current process, instead of
the one identified by the `pid`. (#168, #174)
* Fixed tests that change capabilities to be run in a separate process. (#173)
* Other improvements in tests. (#169, #170)
### Changed
* Use raw syscalls (which are slightly faster). (#176)
* Most tests are now limited to testing the public API of the package. (#162)
* Simplify parsing /proc/*pid*/status, add a test case. (#162)
* Optimize the number of syscall to set ambient capabilities in Apply
by clearing them first; add a test case. (#163, #164)
* Better documentation for [Apply], [NewFile], [NewFile2], [NewPid], [NewPid2]. (#175)
### Removed
* `.golangci.yml` and `.codespellrc` are no longer part of the package. (#158)
## [0.3.0] - 2024-09-25
### Added
* Added [ListKnown] and [ListSupported] functions. (#153)
* [LastCap] is now available on non-Linux platforms (where it returns an error). (#152)
### Changed
* [List] is now deprecated in favor of [ListKnown] and [ListSupported]. (#153)
### Fixed
* Various documentation improvements. (#151)
* Fix "generated code" comment. (#153)
## [0.2.0] - 2024-09-16
This is the first release after the move to a new home in
github.com/moby/sys/capability.
### Fixed
* Fixed URLs in documentation to reflect the new home.
## [0.1.1] - 2024-08-01
This is a maintenance release, fixing a few minor issues.
### Fixed
* Fixed future kernel compatibility, for real this time. [#11]
* Fixed [LastCap] to be a function. [#12]
## [0.1.0] - 2024-07-31
This is an initial release since the fork.
### Breaking changes
* The `CAP_LAST_CAP` variable is removed; users need to modify the code to
use [LastCap] to get the value. [#6]
* The code now requires Go >= 1.21.
### Added
* `go.mod` and `go.sum` files. [#2]
* New [LastCap] function. [#6]
* Basic CI using GHA infra. [#8], [#9]
* README and CHANGELOG. [#10]
### Fixed
* Fixed ambient capabilities error handling in [Apply]. [#3]
* Fixed future kernel compatibility. [#1]
* Fixed various linter warnings. [#4], [#7]
### Changed
* Go build tags changed from old-style (`+build`) to new Go 1.17+ style (`go:build`). [#2]
### Removed
* Removed support for capabilities v1 and v2. [#1]
* Removed init function so programs that use this package start faster. [#6]
* Removed `CAP_LAST_CAP` (use [LastCap] instead). [#6]

# YAML support for the Go language
Introduction
------------
The yaml package enables Go programs to comfortably encode and decode YAML
values. It was developed within [Canonical](https://www.canonical.com) as
part of the [juju](https://juju.ubuntu.com) project, and is based on a
pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
C library to parse and generate YAML data quickly and reliably.
Compatibility
-------------
The yaml package supports most of YAML 1.1 and 1.2, including support for
anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
implemented, and base-60 floats from YAML 1.1 are purposefully not
supported since they're a poor design and are gone in YAML 1.2.
Installation and usage
----------------------
The import path for the package is *go.yaml.in/yaml/v2*.
To install it, run:
go get go.yaml.in/yaml/v2
API documentation
-----------------
See: <https://pkg.go.dev/go.yaml.in/yaml/v2>
API stability
-------------
The package API for yaml v2 will remain stable as described in [gopkg.in](https://gopkg.in).
License
-------
The yaml package is licensed under the Apache License 2.0. Please see the LICENSE file for details.
Example
-------
```Go
package main
import (
"fmt"
"log"
"go.yaml.in/yaml/v2"
)
var data = `
a: Easy!
b:
c: 2
d: [3, 4]
`
// Note: struct fields must be public in order for unmarshal to
// correctly populate the data.
type T struct {
A string
B struct {
RenamedC int `yaml:"c"`
D []int `yaml:",flow"`
}
}
func main() {
t := T{}
err := yaml.Unmarshal([]byte(data), &t)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- t:\n%v\n\n", t)
d, err := yaml.Marshal(&t)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- t dump:\n%s\n\n", string(d))
m := make(map[interface{}]interface{})
err = yaml.Unmarshal([]byte(data), &m)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- m:\n%v\n\n", m)
d, err = yaml.Marshal(&m)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- m dump:\n%s\n\n", string(d))
}
```
This example will generate the following output:
```
--- t:
{Easy! {2 [3 4]}}
--- t dump:
a: Easy!
b:
c: 2
d: [3, 4]
--- m:
map[a:Easy! b:map[c:2 d:[3 4]]]
--- m dump:
a: Easy!
b:
c: 2
d:
- 3
- 4

# YAML support for the Go language
Introduction
------------
The yaml package enables Go programs to comfortably encode and decode YAML
values. It was developed within [Canonical](https://www.canonical.com) as
part of the [juju](https://juju.ubuntu.com) project, and is based on a
pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
C library to parse and generate YAML data quickly and reliably.
Compatibility
-------------
The yaml package supports most of YAML 1.2, but preserves some behavior
from 1.1 for backwards compatibility.
Specifically, as of v3 of the yaml package:
- YAML 1.1 bools (_yes/no, on/off_) are supported as long as they are being
decoded into a typed bool value. Otherwise they behave as a string. Booleans
in YAML 1.2 are _true/false_ only.
- Octals encode and decode as _0777_ per YAML 1.1, rather than _0o777_
as specified in YAML 1.2, because most parsers still use the old format.
Octals in the _0o777_ format are supported though, so new files work.
- Does not support base-60 floats. These are gone from YAML 1.2, and were
actually never supported by this package as it's clearly a poor choice.
and offers backwards
compatibility with YAML 1.1 in some cases.
1.2, including support for
anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
implemented, and base-60 floats from YAML 1.1 are purposefully not
supported since they're a poor design and are gone in YAML 1.2.
Installation and usage
----------------------
The import path for the package is *gopkg.in/yaml.v3*.
To install it, run:
go get gopkg.in/yaml.v3
API documentation
-----------------
If opened in a browser, the import path itself leads to the API documentation:
- [https://gopkg.in/yaml.v3](https://gopkg.in/yaml.v3)
API stability
-------------
The package API for yaml v3 will remain stable as described in [gopkg.in](https://gopkg.in).
License
-------
The yaml package is licensed under the MIT and Apache License 2.0 licenses.
Please see the LICENSE file for details.
Example
-------
```Go
package main
import (
"fmt"
"log"
"gopkg.in/yaml.v3"
)
var data = `
a: Easy!
b:
c: 2
d: [3, 4]
`
// Note: struct fields must be public in order for unmarshal to
// correctly populate the data.
type T struct {
A string
B struct {
RenamedC int `yaml:"c"`
D []int `yaml:",flow"`
}
}
func main() {
t := T{}
err := yaml.Unmarshal([]byte(data), &t)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- t:\n%v\n\n", t)
d, err := yaml.Marshal(&t)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- t dump:\n%s\n\n", string(d))
m := make(map[interface{}]interface{})
err = yaml.Unmarshal([]byte(data), &m)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- m:\n%v\n\n", m)
d, err = yaml.Marshal(&m)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- m dump:\n%s\n\n", string(d))
}
```
This example will generate the following output:
```
--- t:
{Easy! {2 [3 4]}}
--- t dump:
a: Easy!
b:
c: 2
d: [3, 4]
--- m:
map[a:Easy! b:map[c:2 d:[3 4]]]
--- m dump:
a: Easy!
b:
c: 2
d:
- 3
- 4

# YAML marshaling and unmarshaling support for Go
[![Build Status](https://travis-ci.org/kubernetes-sigs/yaml.svg)](https://travis-ci.org/kubernetes-sigs/yaml)
kubernetes-sigs/yaml is a permanent fork of [ghodss/yaml](https://github.com/ghodss/yaml).
## Introduction
A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs.
In short, this library first converts YAML to JSON using go-yaml and then uses `json.Marshal` and `json.Unmarshal` to convert to or from the struct. This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://web.archive.org/web/20190603050330/http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/).
## Compatibility
This package uses [go-yaml](https://github.com/go-yaml/yaml) and therefore supports [everything go-yaml supports](https://github.com/go-yaml/yaml#compatibility).
## Caveats
**Caveat #1:** When using `yaml.Marshal` and `yaml.Unmarshal`, binary data should NOT be preceded with the `!!binary` YAML tag. If you do, go-yaml will convert the binary data from base64 to native binary data, which is not compatible with JSON. You can still use binary in your YAML files though - just store them without the `!!binary` tag and decode the base64 in your code (e.g. in the custom JSON methods `MarshalJSON` and `UnmarshalJSON`). This also has the benefit that your YAML and your JSON binary data will be decoded exactly the same way. As an example:
```
BAD:
exampleKey: !!binary gIGC
GOOD:
exampleKey: gIGC
... and decode the base64 data in your code.
```
**Caveat #2:** When using `YAMLToJSON` directly, maps with keys that are maps will result in an error since this is not supported by JSON. This error will occur in `Unmarshal` as well since you can't unmarshal map keys anyways since struct fields can't be keys.
## Installation and usage
To install, run:
```
$ go get sigs.k8s.io/yaml
```
And import using:
```
import "sigs.k8s.io/yaml"
```
Usage is very similar to the JSON library:
```go
package main
import (
"fmt"
"sigs.k8s.io/yaml"
)
type Person struct {
Name string `json:"name"` // Affects YAML field names too.
Age int `json:"age"`
}
func main() {
// Marshal a Person struct to YAML.
p := Person{"John", 30}
y, err := yaml.Marshal(p)
if err != nil {
fmt.Printf("err: %v\n", err)
return

// Important notes about the Unmarshal logic:
//
// - Decoding is case-insensitive, unlike the rest of Kubernetes API machinery, as this is using the stdlib json library. This might be confusing to users.
// - This decodes any number (although it is an integer) into a float64 if the type of obj is unknown, e.g. *map[string]interface{}, *interface{}, or *[]interface{}. This means integers above +/- 2^53 will lose precision when round-tripping. Make a JSONOpt that calls d.UseNumber() to avoid this.
// - Duplicate fields, including in-case-sensitive matches, are ignored in an undefined order. Note that the YAML specification forbids duplicate fields, so this logic is more permissive than it needs to. See UnmarshalStrict for an alternative.
// - Unknown fields, i.e. serialized data that do not map to a field in obj, are ignored. Use d.DisallowUnknownFields() or UnmarshalStrict to override.
// - As per the YAML 1.1 specification, which yaml.v2 used underneath implements, literal 'yes' and 'no' strings without quotation marks will be converted to true/false implicitly.
