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).

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.

The Parser, on the contrary, -// is a straightforward implementation of a recursive-descendant parser (or, -// LL(1) parser, as it is usually called). -// -// Actually there are two issues of Scanning that might be called "clever", the -// rest is quite straightforward. The issues are "block collection start" and -// "simple keys". Both issues are explained below in details. -// -// Here the Scanning step is explained and implemented.

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 - } - fmt.Println(string(y)) - /* Output: - age: 30 - name: John - */ - - // Unmarshal the YAML back into a Person struct. - var p2 Person - err = yaml.Unmarshal(y, &p2) - if err != nil { - fmt.Printf("err: %v\n", err) - return - } - fmt.Println(p2) - /* Output: - {John 30} - */ -} -``` - -`yaml.YAMLToJSON` and `yaml.JSONToYAML` methods are also available: - -```go -package main - -import ( - "fmt" - - "sigs.k8s.io/yaml" -) - -func main() { - j := []byte(`{"name": "John", "age": 30}`) - y, err := yaml.JSONToYAML(j) - if err != nil { - fmt.Printf("err: %v\n", err) - return - } - fmt.Println(string(y)) - /* Output: - age: 30 - name: John - */ - j2, err := yaml.YAMLToJSON(y) - if err != nil { - fmt.Printf("err: %v\n", err) - return - } - fmt.Println(string(j2)) - /* Output: - {"age":30,"name":"John"} - */ -} -``` diff --git a/vendor/sigs.k8s.io/yaml/RELEASE.md b/vendor/sigs.k8s.io/yaml/RELEASE.md deleted file mode 100644 index 6b642464e..000000000 --- a/vendor/sigs.k8s.io/yaml/RELEASE.md +++ /dev/null @@ -1,9 +0,0 @@ -# Release Process - -The `yaml` Project is released on an as-needed basis.
