Our recommendation instead is to inspect the contents of an untrusted archive before extracting it (this package provides `Walkers`) and decide if you want to proceed with extraction. - ## Project Values This project has a few principle-based goals that guide its development: diff --git a/vendor/github.com/mholt/archiver/v3/archiver.go b/vendor/github.com/mholt/archiver/v3/archiver.go index ecf315e058ab1..b09699d676a48 100644 --- a/vendor/github.com/mholt/archiver/v3/archiver.go +++ b/vendor/github.com/mholt/archiver/v3/archiver.go @@ -72,6 +72,11 @@ type ExtensionChecker interface { CheckExt(name string) error } +// FilenameChecker validates filenames to prevent path traversal attacks +type FilenameChecker interface { + CheckPath(to, filename string) error +} + // Unarchiver is a type that can extract archive files // into a folder. type Unarchiver interface { diff --git a/vendor/github.com/mholt/archiver/v3/azure-pipelines.yml b/vendor/github.com/mholt/archiver/v3/azure-pipelines.yml index a86a62059fa7d..43f19ae8cab14 100644 --- a/vendor/github.com/mholt/archiver/v3/azure-pipelines.yml +++ b/vendor/github.com/mholt/archiver/v3/azure-pipelines.yml @@ -4,10 +4,11 @@ trigger: strategy: matrix: linux: - imageName: ubuntu-16.04 + imageName: ubuntu-18.04 gorootDir: /usr/local mac: - imageName: macos-10.13 + # Mojave + imageName: macos-10.14 gorootDir: /usr/local windows: imageName: windows-2019 @@ -26,6 +27,12 @@ variables: #GO111MODULE: on steps: + +- bash: git config --global core.autocrlf false + displayName: "Disable line ending conversion for git to" + +- checkout: self + - bash: | latestGo=$(curl "https://golang.org/VERSION?m=text") echo "##vso[task.setvariable variable=LATEST_GO]$latestGo" @@ -57,18 +64,16 @@ steps: displayName: Install Go on macOS - powershell: | - Write-Host "Downloading Go...

For example, +the `fs.BuddyInfo()` function reads the file `/proc/buddyinfo`. In addition, the godoc for each public function +should contain the path to the file(s) being read and a URL of the linux kernel documentation describing the file(s). + +### Reading vs. Parsing + +Most functionality in this library consists of reading files and then parsing the text into structured data. In most +cases reading and parsing should be separated into different functions/methods with a public `fs.Thing()` method and +a private `parseThing(r Reader)` function. This provides a logical separation and allows parsing to be tested +directly without the need to read from the filesystem. Using a `Reader` argument is preferred over other data types +such as `string` or `*File` because it provides the most flexibility regarding the data source. When a set of files +in a directory needs to be parsed, then a `path` string parameter to the parse function can be used instead. + +### /proc and /sys filesystem I/O + +The `proc` and `sys` filesystems are pseudo file systems and work a bit differently from standard disk I/O. +Many of the files are changing continuously and the data being read can in some cases change between subsequent +reads in the same file. Also, most of the files are relatively small (less than a few KBs), and system calls +to the `stat` function will often return the wrong size. Therefore, for most files it's recommended to read the +full file in a single operation using an internal utility function called `util.ReadFileNoStat`. +This function is similar to `ioutil.ReadFile`, but it avoids the system call to `stat` to get the current size of +the file. + +Note that parsing the file's contents can still be performed one line at a time. This is done by first reading +the full file, and then using a scanner on the `[]byte` or `string` containing the data. + +``` + data, err := util.ReadFileNoStat("/proc/cpuinfo") + if err != nil { + return err + } + reader := bytes.NewReader(data) + scanner := bufio.NewScanner(reader) +``` + +The `/sys` filesystem contains many very small files which contain only a single numeric or text value. These files +can be read using an internal function called `util.SysReadFile` which is similar to `ioutil.ReadFile` but does +not bother to check the size of the file before reading. +``` + data, err := util.SysReadFile("/sys/class/power_supply/BAT0/capacity") +``` + diff --git a/vendor/github.com/prometheus/procfs/Makefile.common b/vendor/github.com/prometheus/procfs/Makefile.common index d7aea1b86f237..9320176ca24f4 100644 --- a/vendor/github.com/prometheus/procfs/Makefile.common +++ b/vendor/github.com/prometheus/procfs/Makefile.common @@ -69,12 +69,21 @@ else GO_BUILD_PLATFORM ?= $(GOHOSTOS)-$(GOHOSTARCH) endif -PROMU_VERSION ?= 0.4.0 +GOTEST := $(GO) test +GOTEST_DIR := +ifneq ($(CIRCLE_JOB),) +ifneq ($(shell which gotestsum),) + GOTEST_DIR := test-results + GOTEST := gotestsum --junitfile $(GOTEST_DIR)/unit-tests.xml -- +endif +endif + +PROMU_VERSION ?= 0.5.0 PROMU_URL := https://github.com/prometheus/promu/releases/download/v$(PROMU_VERSION)/promu-$(PROMU_VERSION).$(GO_BUILD_PLATFORM).tar.gz GOLANGCI_LINT := GOLANGCI_LINT_OPTS ?= -GOLANGCI_LINT_VERSION ?= v1.16.0 +GOLANGCI_LINT_VERSION ?= v1.18.0 # golangci-lint only supports linux, darwin and windows platforms on i386/amd64. # windows isn't included here because of the path separator being different. ifeq ($(GOHOSTOS),$(filter $(GOHOSTOS),linux darwin)) @@ -86,7 +95,8 @@ endif PREFIX ?= $(shell pwd) BIN_DIR ?= $(shell pwd) DOCKER_IMAGE_TAG ?= $(subst /,-,$(shell git rev-parse --abbrev-ref HEAD)) -DOCKERFILE_PATH ?= ./ +DOCKERFILE_PATH ?= ./Dockerfile +DOCKERBUILD_CONTEXT ?= ./ DOCKER_REPO ?= prom DOCKER_ARCHS ?= amd64 @@ -140,15 +150,29 @@ else $(GO) get $(GOOPTS) -t ./... endif +.PHONY: update-go-deps +update-go-deps: + @echo ">> updating Go dependencies" + @for m in $$($(GO) list -mod=readonly -m -f '{{ if and (not .Indirect) (not .Main)}}{{.Path}}{{end}}' all); do \ + $(GO) get $$m; \ + done + GO111MODULE=$(GO111MODULE) $(GO) mod tidy +ifneq (,$(wildcard vendor)) + GO111MODULE=$(GO111MODULE) $(GO) mod vendor +endif + .PHONY: common-test-short -common-test-short: +common-test-short: $(GOTEST_DIR) @echo ">> running short tests" - GO111MODULE=$(GO111MODULE) $(GO) test -short $(GOOPTS) $(pkgs) + GO111MODULE=$(GO111MODULE) $(GOTEST) -short $(GOOPTS) $(pkgs) .PHONY: common-test -common-test: +common-test: $(GOTEST_DIR) @echo ">> running all tests" - GO111MODULE=$(GO111MODULE) $(GO) test $(test-flags) $(GOOPTS) $(pkgs) + GO111MODULE=$(GO111MODULE) $(GOTEST) $(test-flags) $(GOOPTS) $(pkgs) + +$(GOTEST_DIR): + @mkdir -p $@ .PHONY: common-format common-format: @@ -200,7 +224,7 @@ endif .PHONY: common-build common-build: promu @echo ">> building binaries" - GO111MODULE=$(GO111MODULE) $(PROMU) build --prefix $(PREFIX) + GO111MODULE=$(GO111MODULE) $(PROMU) build --prefix $(PREFIX) $(PROMU_BINARIES) .PHONY: common-tarball common-tarball: promu @@ -211,9 +235,10 @@ common-tarball: promu common-docker: $(BUILD_DOCKER_ARCHS) $(BUILD_DOCKER_ARCHS): common-docker-%: docker build -t "$(DOCKER_REPO)/$(DOCKER_IMAGE_NAME)-linux-$*:$(DOCKER_IMAGE_TAG)" \ + -f $(DOCKERFILE_PATH) \ --build-arg ARCH="$*" \ --build-arg OS="linux" \ - $(DOCKERFILE_PATH) + $(DOCKERBUILD_CONTEXT) .PHONY: common-docker-publish $(PUBLISH_DOCKER_ARCHS) common-docker-publish: $(PUBLISH_DOCKER_ARCHS) diff --git a/vendor/github.com/prometheus/procfs/README.md b/vendor/github.com/prometheus/procfs/README.md index 6f8850feb6783..55d1e3261c9d9 100644 --- a/vendor/github.com/prometheus/procfs/README.md +++ b/vendor/github.com/prometheus/procfs/README.md @@ -1,6 +1,6 @@ # procfs -This procfs package provides functions to retrieve system, kernel and process +This package provides functions to retrieve system, kernel, and process metrics from the pseudo-filesystems /proc and /sys. *WARNING*: This package is a work in progress.

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 any modern Go release. With Go 1.7 and git +installed: + + go get gopkg.in/russross/blackfriday.v2 + +will download, compile, and install the package into your `$GOPATH` +directory hierarchy. Alternatively, you can achieve the same if you +import it into a project: + + import "gopkg.in/russross/blackfriday.v2" + +and `go get` without parameters. + + +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://godoc.org/gopkg.in/russross/blackfriday.v2. + +It is `go get`-able via via [gopkg.in][6] at `gopkg.in/russross/blackfriday.v2`, +but we highly recommend using package management tool like [dep][7] or +[Glide][8] and make use of semantic versioning. With package management you +should import `github.com/russross/blackfriday` and specify that you're using +version 2.0.0. + +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. + +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" +) + +// ... +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`. + +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. + + +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. + +* **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://godoc.org/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://github.com/Ambrevar/Blackfriday-LaTeX): + renders output as LaTeX. + +* [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. + + +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://godoc.org/gopkg.in/russross/blackfriday.v2#Parse "Parse func" + [5]: https://github.com/microcosm-cc/bluemonday "Bluemonday" + [6]: https://labix.org/gopkg.in "gopkg.in" 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 0000000000000..b8607474e599a --- /dev/null +++ b/vendor/github.com/russross/blackfriday/v2/block.go @@ -0,0 +1,1590 @@ +// +// 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" + + "github.com/shurcooL/sanitized_anchor_name" +) + +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: + // + //
