From a78dff7569377ff9e00cf5429a71caf5ef1c7f5056b22acc201ce3c1db0883b2 Mon Sep 17 00:00:00 2001 From: Aleksa Sarai Date: Wed, 27 Nov 2024 12:52:26 +0000 Subject: [PATCH] - Disable docker-buildx builds for SLES. It turns out that build containers with docker-buildx don't currently get the SUSE secrets mounts applied, meaning that container-suseconnect doesn't work when building images. bsc#1233819 OBS-URL: https://build.opensuse.org/package/show/Virtualization:containers/docker?expand=0&rev=419 --- .gitattributes | 23 + .gitignore | 1 + ...llow-directory-creation-in-run-secre.patch | 73 + ...USE-implement-SUSE-container-secrets.patch | 488 + ...rt-graphdriver-btrfs-use-kernel-UAPI.patch | 46 + ...mor-clobber-docker-default-profile-o.patch | 89 + ...armor-remove-version-conditionals-fr.patch | 326 + ...e-to-patched-buildkit-version-to-fix.patch | 890 + ...e-use-AtomicWriteFile-to-save-volume.patch | 53 + 80-docker.rules | 5 + README_SUSE.md | 230 + _service | 30 + ...nclude-required-tools-in-source-tree.patch | 23382 ++++++++++++++++ docker-26.1.4_ce_de5c9cf0b96e.tar.xz | 3 + docker-26.1.5_ce_411e817ddf71.tar.xz | 3 + docker-audit.rules | 27 + docker-buildx-0.17.1.tar.xz | 3 + docker-cli-26.1.4_ce.tar.xz | 3 + docker-cli-26.1.5_ce.tar.xz | 3 + docker-daemon.json | 8 + docker-rpmlintrc | 2 + docker.changes | 4194 +++ docker.service | 45 + docker.socket | 18 + docker.spec | 545 + docker.sysusers | 3 + sysconfig.docker | 8 + 27 files changed, 30501 insertions(+) create mode 100644 .gitattributes create mode 100644 .gitignore create mode 100644 0001-SECRETS-daemon-allow-directory-creation-in-run-secre.patch create mode 100644 0002-SECRETS-SUSE-implement-SUSE-container-secrets.patch create mode 100644 0003-BUILD-SLE12-revert-graphdriver-btrfs-use-kernel-UAPI.patch create mode 100644 0004-bsc1073877-apparmor-clobber-docker-default-profile-o.patch create mode 100644 0005-SLE12-revert-apparmor-remove-version-conditionals-fr.patch create mode 100644 0006-bsc1221916-update-to-patched-buildkit-version-to-fix.patch create mode 100644 0007-bsc1214855-volume-use-AtomicWriteFile-to-save-volume.patch create mode 100644 80-docker.rules create mode 100644 README_SUSE.md create mode 100644 _service create mode 100644 cli-0001-docs-include-required-tools-in-source-tree.patch create mode 100644 docker-26.1.4_ce_de5c9cf0b96e.tar.xz create mode 100644 docker-26.1.5_ce_411e817ddf71.tar.xz create mode 100644 docker-audit.rules create mode 100644 docker-buildx-0.17.1.tar.xz create mode 100644 docker-cli-26.1.4_ce.tar.xz create mode 100644 docker-cli-26.1.5_ce.tar.xz create mode 100644 docker-daemon.json create mode 100644 docker-rpmlintrc create mode 100644 docker.changes create mode 100644 docker.service create mode 100644 docker.socket create mode 100644 docker.spec create mode 100644 docker.sysusers create mode 100644 sysconfig.docker diff --git a/.gitattributes b/.gitattributes new file mode 100644 index 0000000..9b03811 --- /dev/null +++ b/.gitattributes @@ -0,0 +1,23 @@ +## Default LFS +*.7z filter=lfs diff=lfs merge=lfs -text +*.bsp filter=lfs diff=lfs merge=lfs -text +*.bz2 filter=lfs diff=lfs merge=lfs -text +*.gem filter=lfs diff=lfs merge=lfs -text +*.gz filter=lfs diff=lfs merge=lfs -text +*.jar filter=lfs diff=lfs merge=lfs -text +*.lz filter=lfs diff=lfs merge=lfs -text +*.lzma filter=lfs diff=lfs merge=lfs -text +*.obscpio filter=lfs diff=lfs merge=lfs -text +*.oxt filter=lfs diff=lfs merge=lfs -text +*.pdf filter=lfs diff=lfs merge=lfs -text +*.png filter=lfs diff=lfs merge=lfs -text +*.rpm filter=lfs diff=lfs merge=lfs -text +*.tbz filter=lfs diff=lfs merge=lfs -text +*.tbz2 filter=lfs diff=lfs merge=lfs -text +*.tgz filter=lfs diff=lfs merge=lfs -text +*.ttf filter=lfs diff=lfs merge=lfs -text +*.txz filter=lfs diff=lfs merge=lfs -text +*.whl filter=lfs diff=lfs merge=lfs -text +*.xz filter=lfs diff=lfs merge=lfs -text +*.zip filter=lfs diff=lfs merge=lfs -text +*.zst filter=lfs diff=lfs merge=lfs -text diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..57affb6 --- /dev/null +++ b/.gitignore @@ -0,0 +1 @@ +.osc diff --git a/0001-SECRETS-daemon-allow-directory-creation-in-run-secre.patch b/0001-SECRETS-daemon-allow-directory-creation-in-run-secre.patch new file mode 100644 index 0000000..1e84c9a --- /dev/null +++ b/0001-SECRETS-daemon-allow-directory-creation-in-run-secre.patch @@ -0,0 +1,73 @@ +From ec53ee338835c4c1dc583695ac166f36bf3bac5c Mon Sep 17 00:00:00 2001 +From: Aleksa Sarai +Date: Wed, 8 Mar 2017 12:41:54 +1100 +Subject: [PATCH 1/7] SECRETS: daemon: allow directory creation in /run/secrets + +Since FileMode can have the directory bit set, allow a SecretStore +implementation to return secrets that are actually directories.

Refer to the [official documentation](http://docs.docker.com/articles/security/) + for more details. + +## Container drivers + +Docker has different backend drivers to handle the containers. The recommended +on is [libcontainer](https://github.com/docker/libcontainer), which is also the +default choice. This driver provides direct access with cgroups. + +The Docker packages ships also a LXC driver which handles containers using the +LXC tools. + +At the time of writing, upstream is working on a `libvirt-lxc` driver. + +## Storage drivers + +Docker supports different storage drivers: + + * `vfs`: this driver is automatically used when the Docker host filesystem + does not support copy-on-write. This is a simple driver which does not offer + some of the advantages of Docker (like sharing layers, more on that in the + next sections). It is highly reliable but also slow. + * `devicemapper`: this driver relies on the device-mapper thin provisioning + module. It supports copy-on-write, hence it offers all the advantages of + Docker. + * `btrfs`: this driver relies on Btrfs to provide all the features required + by Docker. To use this driver the `/var/lib/docker` directory must be on a + btrfs filesystem. + * `AUFS`: this driver relies on AUFS union filesystem. Neither the upstream + kernel nor the SUSE one supports this filesystem. Hence the AUFS driver is + not built into the SUSE Docker package. + +It is possible to specify which driver to use by changing the value of the +`DOCKER_OPTS` variable defined inside of the `/etc/sysconfig/docker` file. +This can be done either manually or using &yast; by browsing to: + * System + * /etc/sysconfig Editor + * System + * Management + * DOCKER_OPTS +menu and entering the `-s storage_driver` string. + +For example, to force the usage of the `devicemapper` driver +enter the following text: +``` +DOCKER_OPTS="-s devicemapper +``` + +It is recommended to have `/var/lib/docker` mounted on a different filesystem +to not affect the Docker host OS in case of a filesystem corruption. + +# Setting up a Docker host + +Prepare the host: + + 1. Install the `docker` package. + 2. Automatically start the Docker daemon at boot: + `sudo systemctl enable docker` + 3. Start the Docker daemon: + `sudo systemctl start docker` + +The Docker daemon listens on a local socket which is accessible only by the `root` +user and by the members of the `docker` group. + +The `docker` group is automatically created at package installation time.

The right approach is to build +the [base images](http://docs.docker.com/terms/image/#base-image-def) using KIWI +and then use them as foundation blocks inside of your Docker's build system. + +That two advantages: + + 1. Be able to use docker specific directives (like `ENTRYPOINT`, `EXPOSE`, ...). + 2. Be able to reuse already existing layers. + +Sharing the common layers between different images makes possible to: + + * Use less disk space on the Docker hosts. + * Make the deployments faster: only the requested layers are sent over the + network (it is like upgrading installed packages using delta rpms). + * Take full advantage of caching while building Docker images: this will result + in faster executions of `docker build` command. + +To recap: KIWI is not to be intended as a replacement for Docker's build system. +It rather complements with it. + diff --git a/_service b/_service new

It ++is paranoid about its input (so you can safely feed it user-supplied ++data), it is fast, it supports common extensions (tables, smart ++punctuation substitutions, etc.), and it is safe for all utf-8 ++(unicode) input. ++ ++HTML output is currently supported, along with Smartypants ++extensions. ++ ++It started as a translation from C of [Sundown][3]. ++ ++ ++Installation ++------------ ++ ++Blackfriday is compatible with modern Go releases in module mode. ++With Go installed: ++ ++ go get github.com/russross/blackfriday/v2 ++ ++will resolve and add the package to the current development module, ++then build and install it. Alternatively, you can achieve the same ++if you import it in a package: ++ ++ import "github.com/russross/blackfriday/v2" ++ ++and `go get` without parameters. ++ ++Legacy GOPATH mode is unsupported. ++ ++ ++Versions ++-------- ++ ++Currently maintained and recommended version of Blackfriday is `v2`. It's being ++developed on its own branch: https://github.com/russross/blackfriday/tree/v2 and the ++documentation is available at ++https://pkg.go.dev/github.com/russross/blackfriday/v2. ++ ++It is `go get`-able in module mode at `github.com/russross/blackfriday/v2`. ++ ++Version 2 offers a number of improvements over v1: ++ ++* Cleaned up API ++* A separate call to [`Parse`][4], which produces an abstract syntax tree for ++ the document ++* Latest bug fixes ++* Flexibility to easily add your own rendering extensions ++ ++Potential drawbacks: ++ ++* Our benchmarks show v2 to be slightly slower than v1. Currently in the ++ ballpark of around 15%. ++* API breakage. If you can't afford modifying your code to adhere to the new API ++ and don't care too much about the new features, v2 is probably not for you. ++* Several bug fixes are trailing behind and still need to be forward-ported to ++ v2. See issue [#348](https://github.com/russross/blackfriday/issues/348) for ++ tracking. ++ ++If you are still interested in the legacy `v1`, you can import it from ++`github.com/russross/blackfriday`. Documentation for the legacy v1 can be found ++here: https://pkg.go.dev/github.com/russross/blackfriday. ++ ++ ++Usage ++----- ++ ++For the most sensible markdown processing, it is as simple as getting your input ++into a byte slice and calling: ++ ++```go ++output := blackfriday.Run(input) ++``` ++ ++Your input will be parsed and the output rendered with a set of most popular ++extensions enabled. If you want the most basic feature set, corresponding with ++the bare Markdown specification, use: ++ ++```go ++output := blackfriday.Run(input, blackfriday.WithNoExtensions()) ++``` ++ ++### Sanitize untrusted content ++ ++Blackfriday itself does nothing to protect against malicious content. If you are ++dealing with user-supplied markdown, we recommend running Blackfriday's output ++through HTML sanitizer such as [Bluemonday][5]. ++ ++Here's an example of simple usage of Blackfriday together with Bluemonday: ++ ++```go ++import ( ++ "github.com/microcosm-cc/bluemonday" ++ "github.com/russross/blackfriday/v2" ++) ++ ++// ... ++unsafe := blackfriday.Run(input) ++html := bluemonday.UGCPolicy().SanitizeBytes(unsafe) ++``` ++ ++### Custom options ++ ++If you want to customize the set of options, use `blackfriday.WithExtensions`, ++`blackfriday.WithRenderer` and `blackfriday.WithRefOverride`. ++ ++### `blackfriday-tool` ++ ++You can also check out `blackfriday-tool` for a more complete example ++of how to use it. Download and install it using: ++ ++ go get github.com/russross/blackfriday-tool ++ ++This is a simple command-line tool that allows you to process a ++markdown file using a standalone program. You can also browse the ++source directly on github if you are just looking for some example ++code: ++ ++* ++ ++Note that if you have not already done so, installing ++`blackfriday-tool` will be sufficient to download and install ++blackfriday in addition to the tool itself. The tool binary will be ++installed in `$GOPATH/bin`. This is a statically-linked binary that ++can be copied to wherever you need it without worrying about ++dependencies and library versions. ++ ++### Sanitized anchor names ++ ++Blackfriday includes an algorithm for creating sanitized anchor names ++corresponding to a given input text. This algorithm is used to create ++anchors for headings when `AutoHeadingIDs` extension is enabled. The ++algorithm has a specification, so that other packages can create ++compatible anchor names and links to those anchors. ++ ++The specification is located at https://pkg.go.dev/github.com/russross/blackfriday/v2#hdr-Sanitized_Anchor_Names. ++ ++[`SanitizedAnchorName`](https://pkg.go.dev/github.com/russross/blackfriday/v2#SanitizedAnchorName) exposes this functionality, and can be used to ++create compatible links to the anchor names generated by blackfriday. ++This algorithm is also implemented in a small standalone package at ++[`github.com/shurcooL/sanitized_anchor_name`](https://pkg.go.dev/github.com/shurcooL/sanitized_anchor_name). It can be useful for clients ++that want a small package and don't need full functionality of blackfriday. ++ ++ ++Features ++-------- ++ ++All features of Sundown are supported, including: ++ ++* **Compatibility**. The Markdown v1.0.3 test suite passes with ++ the `--tidy` option. Without `--tidy`, the differences are ++ mostly in whitespace and entity escaping, where blackfriday is ++ more consistent and cleaner. ++ ++* **Common extensions**, including table support, fenced code ++ blocks, autolinks, strikethroughs, non-strict emphasis, etc. ++ ++* **Safety**. Blackfriday is paranoid when parsing, making it safe ++ to feed untrusted user input without fear of bad things ++ happening. The test suite stress tests this and there are no ++ known inputs that make it crash. If you find one, please let me ++ know and send me the input that does it. ++ ++ NOTE: "safety" in this context means *runtime safety only*. In order to ++ protect yourself against JavaScript injection in untrusted content, see ++ [this example](https://github.com/russross/blackfriday#sanitize-untrusted-content). ++ ++* **Fast processing**. It is fast enough to render on-demand in ++ most web applications without having to cache the output. ++ ++* **Thread safety**. You can run multiple parsers in different ++ goroutines without ill effect. There is no dependence on global ++ shared state. ++ ++* **Minimal dependencies**. Blackfriday only depends on standard ++ library packages in Go. The source code is pretty ++ self-contained, so it is easy to add to any project, including ++ Google App Engine projects. ++ ++* **Standards compliant**. Output successfully validates using the ++ W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional. ++ ++ ++Extensions ++---------- ++ ++In addition to the standard markdown syntax, this package ++implements the following extensions: ++ ++* **Intra-word emphasis supression**. The `_` character is ++ commonly used inside words when discussing code, so having ++ markdown interpret it as an emphasis command is usually the ++ wrong thing. Blackfriday lets you treat all emphasis markers as ++ normal characters when they occur inside a word. ++ ++* **Tables**. Tables can be created by drawing them in the input ++ using a simple syntax: ++ ++ ``` ++ Name | Age ++ --------|------ ++ Bob | 27 ++ Alice | 23 ++ ``` ++ ++* **Fenced code blocks**. In addition to the normal 4-space ++ indentation to mark code blocks, you can explicitly mark them ++ and supply a language (to make syntax highlighting simple). Just ++ mark it like this: ++ ++ ```go ++ func getTrue() bool { ++ return true ++ } ++ ``` ++ ++ You can use 3 or more backticks to mark the beginning of the ++ block, and the same number to mark the end of the block. ++ ++ To preserve classes of fenced code blocks while using the bluemonday ++ HTML sanitizer, use the following policy: ++ ++ ```go ++ p := bluemonday.UGCPolicy() ++ p.AllowAttrs("class").Matching(regexp.MustCompile("^language-[a-zA-Z0-9]+$")).OnElements("code") ++ html := p.SanitizeBytes(unsafe) ++ ``` ++ ++* **Definition lists**. A simple definition list is made of a single-line ++ term followed by a colon and the definition for that term. ++ ++ Cat ++ : Fluffy animal everyone likes ++ ++ Internet ++ : Vector of transmission for pictures of cats ++ ++ Terms must be separated from the previous definition by a blank line. ++ ++* **Footnotes**. A marker in the text that will become a superscript number; ++ a footnote definition that will be placed in a list of footnotes at the ++ end of the document. A footnote looks like this: ++ ++ This is a footnote.[^1] ++ ++ [^1]: the footnote text. ++ ++* **Autolinking**. Blackfriday can find URLs that have not been ++ explicitly marked as links and turn them into links. ++ ++* **Strikethrough**. Use two tildes (`~~`) to mark text that ++ should be crossed out. ++ ++* **Hard line breaks**. With this extension enabled newlines in the input ++ translate into line breaks in the output. This extension is off by default. ++ ++* **Smart quotes**. Smartypants-style punctuation substitution is ++ supported, turning normal double- and single-quote marks into ++ curly quotes, etc. ++ ++* **LaTeX-style dash parsing** is an additional option, where `--` ++ is translated into `–`, and `---` is translated into ++ `—`. This differs from most smartypants processors, which ++ turn a single hyphen into an ndash and a double hyphen into an ++ mdash. ++ ++* **Smart fractions**, where anything that looks like a fraction ++ is translated into suitable HTML (instead of just a few special ++ cases like most smartypant processors). For example, `4/5` ++ becomes `4⁄5`, which renders as ++ 4⁄5. ++ ++ ++Other renderers ++--------------- ++ ++Blackfriday is structured to allow alternative rendering engines. Here ++are a few of note: ++ ++* [github_flavored_markdown](https://pkg.go.dev/github.com/shurcooL/github_flavored_markdown): ++ provides a GitHub Flavored Markdown renderer with fenced code block ++ highlighting, clickable heading anchor links. ++ ++ It's not customizable, and its goal is to produce HTML output ++ equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode), ++ except the rendering is performed locally. ++ ++* [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt, ++ but for markdown. ++ ++* [LaTeX output](https://gitlab.com/ambrevar/blackfriday-latex): ++ renders output as LaTeX. ++ ++* [bfchroma](https://github.com/Depado/bfchroma/): provides convenience ++ integration with the [Chroma](https://github.com/alecthomas/chroma) code ++ highlighting library. bfchroma is only compatible with v2 of Blackfriday and ++ provides a drop-in renderer ready to use with Blackfriday, as well as ++ options and means for further customization. ++ ++* [Blackfriday-Confluence](https://github.com/kentaro-m/blackfriday-confluence): provides a [Confluence Wiki Markup](https://confluence.atlassian.com/doc/confluence-wiki-markup-251003035.html) renderer. ++ ++* [Blackfriday-Slack](https://github.com/karriereat/blackfriday-slack): converts markdown to slack message style ++ ++ ++TODO ++---- ++ ++* More unit testing ++* Improve Unicode support. It does not understand all Unicode ++ rules (about what constitutes a letter, a punctuation symbol, ++ etc.), so it may fail to detect word boundaries correctly in ++ some instances. It is safe on all UTF-8 input. ++ ++ ++License ++------- ++ ++[Blackfriday is distributed under the Simplified BSD License](LICENSE.txt) ++ ++ ++ [1]: https://daringfireball.net/projects/markdown/ "Markdown" ++ [2]: https://golang.org/ "Go Language" ++ [3]: https://github.com/vmg/sundown "Sundown" ++ [4]: https://pkg.go.dev/github.com/russross/blackfriday/v2#Parse "Parse func" ++ [5]: https://github.com/microcosm-cc/bluemonday "Bluemonday" ++ ++ [BuildV2SVG]: https://travis-ci.org/russross/blackfriday.svg?branch=v2 ++ [BuildV2URL]: https://travis-ci.org/russross/blackfriday ++ [PkgGoDevV2SVG]: https://pkg.go.dev/badge/github.com/russross/blackfriday/v2 ++ [PkgGoDevV2URL]: https://pkg.go.dev/github.com/russross/blackfriday/v2 +diff --git a/vendor/github.com/russross/blackfriday/v2/block.go b/vendor/github.com/russross/blackfriday/v2/block.go +new file mode 100644 +index 000000000000..dcd61e6e35bc +--- /dev/null ++++ b/vendor/github.com/russross/blackfriday/v2/block.go +@@ -0,0 +1,1612 @@ ++// ++// Blackfriday Markdown Processor ++// Available at http://github.com/russross/blackfriday ++// ++// Copyright © 2011 Russ Ross . ++// Distributed under the Simplified BSD License. ++// See README.md for details. ++// ++ ++// ++// Functions to parse block-level elements. ++// ++ ++package blackfriday ++ ++import ( ++ "bytes" ++ "html" ++ "regexp" ++ "strings" ++ "unicode" ++) ++ ++const ( ++ charEntity = "&(?:#x[a-f0-9]{1,8}|#[0-9]{1,8}|[a-z][a-z0-9]{1,31});" ++ escapable = "[!\"#$%&'()*+,./:;<=>?@[\\\\\\]^_`{|}~-]" ++) ++ ++var ( ++ reBackslashOrAmp = regexp.MustCompile("[\\&]") ++ reEntityOrEscapedChar = regexp.MustCompile("(?i)\\\\" + escapable + "|" + charEntity) ++) ++ ++// Parse block-level data. ++// Note: this function and many that it calls assume that ++// the input buffer ends with a newline. ++func (p *Markdown) block(data []byte) { ++ // this is called recursively: enforce a maximum depth ++ if p.nesting >= p.maxNesting { ++ return ++ } ++ p.nesting++ ++ ++ // parse out one block-level construct at a time ++ for len(data) > 0 { ++ // prefixed heading: ++ // ++ // # Heading 1 ++ // ## Heading 2 ++ // ... ++ // ###### Heading 6 ++ if p.isPrefixHeading(data) { ++ data = data[p.prefixHeading(data):] ++ continue ++ } ++ ++ // block of preformatted HTML: ++ // ++ //

This algorithm is used to create ++// anchors for headings when AutoHeadingIDs extension is enabled. The ++// algorithm is specified below, so that other packages can create ++// compatible anchor names and links to those anchors. ++// ++// The algorithm iterates over the input text, interpreted as UTF-8, ++// one Unicode code point (rune) at a time. All runes that are letters (category L) ++// or numbers (category N) are considered valid characters. They are mapped to ++// lower case, and included in the output. All other runes are considered ++// invalid characters. Invalid characters that precede the first valid character, ++// as well as invalid character that follow the last valid character ++// are dropped completely. All other sequences of invalid characters ++// between two valid characters are replaced with a single dash character '-'. ++// ++// SanitizedAnchorName exposes this functionality, and can be used to ++// create compatible links to the anchor names generated by blackfriday. ++// This algorithm is also implemented in a small standalone package at ++// github.com/shurcooL/sanitized_anchor_name. It can be useful for clients ++// that want a small package and don't need full functionality of blackfriday. ++package blackfriday ++ ++// NOTE: Keep Sanitized Anchor Name algorithm in sync with

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 ++``` ++ +diff --git a/vendor/gopkg.in/yaml.v3/apic.go b/vendor/gopkg.in/yaml.v3/apic.go +new file mode 100644 +index 000000000000..ae7d049f182a +--- /dev/null ++++ b/vendor/gopkg.in/yaml.v3/apic.go +@@ -0,0 +1,747 @@ ++// ++// Copyright (c) 2011-2019 Canonical Ltd ++// Copyright (c) 2006-2010 Kirill Simonov ++// ++// Permission is hereby granted, free of charge, to any person obtaining a copy of ++// this software and associated documentation files (the "Software"), to deal in ++// the Software without restriction, including without limitation the rights to ++// use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies ++// of the Software, and to permit persons to whom the Software is furnished to do ++// so, subject to the following conditions: ++// ++// The above copyright notice and this permission notice shall be included in all ++// copies or substantial portions of the Software. ++// ++// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR ++// IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, ++// FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

The issues are "block collection start" and ++// "simple keys". Both issues are explained below in details. ++// ++// Here the Scanning step is explained and implemented. We start with the list ++// of all the tokens produced by the Scanner together with short descriptions. ++// ++// Now, tokens: ++// ++// STREAM-START(encoding) # The stream start. ++// STREAM-END # The stream end. ++// VERSION-DIRECTIVE(major,minor) # The '%YAML' directive. ++// TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive. ++// DOCUMENT-START # '---' ++// DOCUMENT-END # '...' ++// BLOCK-SEQUENCE-START # Indentation increase denoting a block ++// BLOCK-MAPPING-START # sequence or a block mapping. ++// BLOCK-END # Indentation decrease. ++// FLOW-SEQUENCE-START # '[' ++// FLOW-SEQUENCE-END # ']' ++// BLOCK-SEQUENCE-START # '{' ++// BLOCK-SEQUENCE-END # '}' ++// BLOCK-ENTRY # '-' ++// FLOW-ENTRY # ',' ++// KEY # '?' or nothing (simple keys). ++// VALUE # ':' ++// ALIAS(anchor) # '*anchor' ++// ANCHOR(anchor) # '&anchor' ++// TAG(handle,suffix) # '!handle!suffix' ++// SCALAR(value,style) # A scalar. ++// ++// The following two tokens are "virtual" tokens denoting the beginning and the ++// end of the stream: ++// ++// STREAM-START(encoding) ++// STREAM-END ++// ++// We pass the information about the input stream encoding with the ++// STREAM-START token. ++// ++// The next two tokens are responsible for tags: ++// ++// VERSION-DIRECTIVE(major,minor) ++// TAG-DIRECTIVE(handle,prefix) ++// ++// Example: ++// ++// %YAML 1.1 ++// %TAG ! !foo ++// %TAG !yaml! tag:yaml.org,2002: ++// --- ++// ++// The correspoding sequence of tokens: ++// ++// STREAM-START(utf-8) ++// VERSION-DIRECTIVE(1,1) ++// TAG-DIRECTIVE("!","!foo") ++// TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:") ++// DOCUMENT-START ++// STREAM-END ++// ++// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole ++// line. ++// ++// The document start and end indicators are represented by: ++// ++// DOCUMENT-START ++// DOCUMENT-END ++// ++// Note that if a YAML stream contains an implicit document (without '---' ++// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be ++// produced. ++// ++// In the following examples, we present whole documents together with the ++// produced tokens. ++// ++// 1. An implicit document: ++// ++// 'a scalar' ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// SCALAR("a scalar",single-quoted) ++// STREAM-END ++// ++// 2. An explicit document: ++// ++// --- ++// 'a scalar' ++// ... ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// DOCUMENT-START ++// SCALAR("a scalar",single-quoted) ++// DOCUMENT-END ++// STREAM-END ++// ++// 3. Several documents in a stream: ++// ++// 'a scalar' ++// --- ++// 'another scalar' ++// --- ++// 'yet another scalar' ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// SCALAR("a scalar",single-quoted) ++// DOCUMENT-START ++// SCALAR("another scalar",single-quoted) ++// DOCUMENT-START ++// SCALAR("yet another scalar",single-quoted) ++// STREAM-END ++// ++// We have already introduced the SCALAR token above. The following tokens are ++// used to describe aliases, anchors, tag, and scalars: ++// ++// ALIAS(anchor) ++// ANCHOR(anchor) ++// TAG(handle,suffix) ++// SCALAR(value,style) ++// ++// The following series of examples illustrate the usage of these tokens: ++// ++// 1. A recursive sequence: ++// ++// &A [ *A ] ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// ANCHOR("A") ++// FLOW-SEQUENCE-START ++// ALIAS("A") ++// FLOW-SEQUENCE-END ++// STREAM-END ++// ++// 2. A tagged scalar: ++// ++// !!float "3.14" # A good approximation. ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// TAG("!!","float") ++// SCALAR("3.14",double-quoted) ++// STREAM-END ++// ++// 3. Various scalar styles: ++// ++// --- # Implicit empty plain scalars do not produce tokens. ++// --- a plain scalar ++// --- 'a single-quoted scalar' ++// --- "a double-quoted scalar" ++// --- |- ++// a literal scalar ++// --- >- ++// a folded ++// scalar ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// DOCUMENT-START ++// DOCUMENT-START ++// SCALAR("a plain scalar",plain) ++// DOCUMENT-START ++// SCALAR("a single-quoted scalar",single-quoted) ++// DOCUMENT-START ++// SCALAR("a double-quoted scalar",double-quoted) ++// DOCUMENT-START ++// SCALAR("a literal scalar",literal) ++// DOCUMENT-START ++// SCALAR("a folded scalar",folded) ++// STREAM-END ++// ++// Now it's time to review collection-related tokens. We will start with ++// flow collections: ++// ++// FLOW-SEQUENCE-START ++// FLOW-SEQUENCE-END ++// FLOW-MAPPING-START ++// FLOW-MAPPING-END ++// FLOW-ENTRY ++// KEY ++// VALUE ++// ++// The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and ++// FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}' ++// correspondingly. FLOW-ENTRY represent the ',' indicator. Finally the ++// indicators '?' and ':', which are used for denoting mapping keys and values, ++// are represented by the KEY and VALUE tokens. ++// ++// The following examples show flow collections: ++// ++// 1. A flow sequence: ++// ++// [item 1, item 2, item 3] ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// FLOW-SEQUENCE-START ++// SCALAR("item 1",plain) ++// FLOW-ENTRY ++// SCALAR("item 2",plain) ++// FLOW-ENTRY ++// SCALAR("item 3",plain) ++// FLOW-SEQUENCE-END ++// STREAM-END ++// ++// 2. A flow mapping: ++// ++// { ++// a simple key: a value, # Note that the KEY token is produced. ++// ? a complex key: another value, ++// } ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// FLOW-MAPPING-START ++// KEY ++// SCALAR("a simple key",plain) ++// VALUE ++// SCALAR("a value",plain) ++// FLOW-ENTRY ++// KEY ++// SCALAR("a complex key",plain) ++// VALUE ++// SCALAR("another value",plain) ++// FLOW-ENTRY ++// FLOW-MAPPING-END ++// STREAM-END ++// ++// A simple key is a key which is not denoted by the '?' indicator. Note that ++// the Scanner still produce the KEY token whenever it encounters a simple key. ++// ++// For scanning block collections, the following tokens are used (note that we ++// repeat KEY and VALUE here): ++// ++// BLOCK-SEQUENCE-START ++// BLOCK-MAPPING-START ++// BLOCK-END ++// BLOCK-ENTRY ++// KEY ++// VALUE ++// ++// The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation ++// increase that precedes a block collection (cf. the INDENT token in Python). ++// The token BLOCK-END denote indentation decrease that ends a block collection ++// (cf. the DEDENT token in Python). However YAML has some syntax pecularities ++// that makes detections of these tokens more complex. ++// ++// The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators ++// '-', '?', and ':' correspondingly. ++// ++// The following examples show how the tokens BLOCK-SEQUENCE-START, ++// BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner: ++// ++// 1. Block sequences: ++// ++// - item 1 ++// - item 2 ++// - ++// - item 3.1 ++// - item 3.2 ++// - ++// key 1: value 1 ++// key 2: value 2 ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// BLOCK-SEQUENCE-START ++// BLOCK-ENTRY ++// SCALAR("item 1",plain) ++// BLOCK-ENTRY ++// SCALAR("item 2",plain) ++// BLOCK-ENTRY ++// BLOCK-SEQUENCE-START ++// BLOCK-ENTRY ++// SCALAR("item 3.1",plain) ++// BLOCK-ENTRY ++// SCALAR("item 3.2",plain) ++// BLOCK-END ++// BLOCK-ENTRY ++// BLOCK-MAPPING-START ++// KEY ++// SCALAR("key 1",plain) ++// VALUE ++// SCALAR("value 1",plain) ++// KEY ++// SCALAR("key 2",plain) ++// VALUE ++// SCALAR("value 2",plain) ++// BLOCK-END ++// BLOCK-END ++// STREAM-END ++// ++// 2. Block mappings: ++// ++// a simple key: a value # The KEY token is produced here. ++// ? a complex key ++// : another value ++// a mapping: ++// key 1: value 1 ++// key 2: value 2 ++// a sequence: ++// - item 1 ++// - item 2 ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// BLOCK-MAPPING-START ++// KEY ++// SCALAR("a simple key",plain) ++// VALUE ++// SCALAR("a value",plain) ++// KEY ++// SCALAR("a complex key",plain) ++// VALUE ++// SCALAR("another value",plain) ++// KEY ++// SCALAR("a mapping",plain) ++// BLOCK-MAPPING-START ++// KEY ++// SCALAR("key 1",plain) ++// VALUE ++// SCALAR("value 1",plain) ++// KEY ++// SCALAR("key 2",plain) ++// VALUE ++// SCALAR("value 2",plain) ++// BLOCK-END ++// KEY ++// SCALAR("a sequence",plain) ++// VALUE ++// BLOCK-SEQUENCE-START ++// BLOCK-ENTRY ++// SCALAR("item 1",plain) ++// BLOCK-ENTRY ++// SCALAR("item 2",plain) ++// BLOCK-END ++// BLOCK-END ++// STREAM-END ++// ++// YAML does not always require to start a new block collection from a new ++// line. If the current line contains only '-', '?', and ':' indicators, a new ++// block collection may start at the current line. The following examples ++// illustrate this case: ++// ++// 1. Collections in a sequence: ++// ++// - - item 1 ++// - item 2 ++// - key 1: value 1 ++// key 2: value 2 ++// - ? complex key ++// : complex value ++// ++// Tokens: ++// ++// STREAM-START(utf-8) ++// BLOCK-SEQUENCE-START ++// BLOCK-ENTRY ++// BLOCK-SEQUENCE-START ++// BLOCK-ENTRY ++// SCALAR("item 1",plain) ++// BLOCK-ENTRY ++// SCALAR("item 2",plain) ++// BLOCK-END ++// BLOCK-ENTRY ++// BLOCK-MAPPING-START ++// KEY ++// SCALAR("key 1",plain) ++// VALUE ++// SCALAR("value 1",plain) ++// KEY ++// SCALAR("key 2",plain) ++// VALUE ++// SCALAR("value 2",plain) ++// BLOCK-END ++// BLOCK-ENTRY ++// BLOCK-MAPPING-START ++// KEY ++// SCALAR("complex key") ++// VALUE ++// SCALAR("complex value") ++// BLOCK-END ++// BLOCK-END ++// STREAM-END ++// ++// 2.
