For example, the SDKs take care +// of cryptographically signing requests, managing errors, and retrying requests +// automatically. For information about the AWS SDKs, including how to download +// and install them, see the Tools for Amazon Web Services page (http://aws.amazon.com/tools/). +// +// For information about setting up signatures and authorization through the +// API, go to Signing AWS API Requests (http://docs.aws.amazon.com/general/latest/gr/signing_aws_api_requests.html) +// in the AWS General Reference.

See the +sections below for further details on formatting and configuration options. + +To dump a variable with full newlines, indentation, type, and pointer +information use Dump, Fdump, or Sdump: + spew.Dump(myVar1, myVar2, ...) + spew.Fdump(someWriter, myVar1, myVar2, ...) + str := spew.Sdump(myVar1, myVar2, ...) + +Alternatively, if you would prefer to use format strings with a compacted inline +printing style, use the convenience wrappers Printf, Fprintf, etc with +%v (most compact), %+v (adds pointer addresses), %#v (adds types), or +%#+v (adds types and pointer addresses): + spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + +Configuration Options + +Configuration of spew is handled by fields in the ConfigState type. For +convenience, all of the top-level functions use a global state available +via the spew.Config global. + +It is also possible to create a ConfigState instance that provides methods +equivalent to the top-level functions. This allows concurrent configuration +options. See the ConfigState documentation for more details. + +The following configuration options are available: + * Indent + String to use for each indentation level for Dump functions. + It is a single space by default. A popular alternative is "\t". + + * MaxDepth + Maximum number of levels to descend into nested data structures. + There is no limit by default. + + * DisableMethods + Disables invocation of error and Stringer interface methods. + Method invocation is enabled by default. + + * DisablePointerMethods + Disables invocation of error and Stringer interface methods on types + which only accept pointer receivers from non-pointer variables. + Pointer method invocation is enabled by default. + + * DisablePointerAddresses + DisablePointerAddresses specifies whether to disable the printing of + pointer addresses. This is useful when diffing data structures in tests. + + * DisableCapacities + DisableCapacities specifies whether to disable the printing of + capacities for arrays, slices, maps and channels. This is useful when + diffing data structures in tests. + + * ContinueOnMethod + Enables recursion into types after invoking error and Stringer interface + methods. Recursion after method invocation is disabled by default. + + * SortKeys + Specifies map keys should be sorted before being printed. Use + this to have a more deterministic, diffable output. Note that + only native types (bool, int, uint, floats, uintptr and string) + and types which implement error or Stringer interfaces are + supported with other types sorted according to the + reflect.Value.String() output which guarantees display + stability. Natural map order is used by default. + + * SpewKeys + Specifies that, as a last resort attempt, map keys should be + spewed to strings and sorted by those strings. This is only + considered if SortKeys is true. + +Dump Usage + +Simply call spew.Dump with a list of variables you want to dump: + + spew.Dump(myVar1, myVar2, ...) + +You may also call spew.Fdump if you would prefer to output to an arbitrary +io.Writer. For example, to dump to standard error: + + spew.Fdump(os.Stderr, myVar1, myVar2, ...) + +A third option is to call spew.Sdump to get the formatted output as a string: + + str := spew.Sdump(myVar1, myVar2, ...) + +Sample Dump Output + +See the Dump example for details on the setup of the types and variables being +shown here. + + (main.Foo) { + unexportedField: (*main.Bar)(0xf84002e210)({ + flag: (main.Flag) flagTwo, + data: (uintptr) + }), + ExportedField: (map[interface {}]interface {}) (len=1) { + (string) (len=3) "one": (bool) true + } + } + +Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C +command as shown. + ([]uint8) (len=32 cap=32) { + 00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... | + 00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0| + 00000020 31 32 |12| + } + +Custom Formatter + +Spew provides a custom formatter that implements the fmt.Formatter interface +so that it integrates cleanly with standard fmt package printing functions.

Also when you set `cfg.BlockMode = false`, this one is about **10-30%** faster. + +To make those changes I have to confirm API broken, so it's safer to keep it in another place and start using `gopkg.in` to version my package at this time.(PS: shorter import path) + +## License + +This project is under Apache v2 License.

+ +## 高级用法 + +### 递归读取键值 + +在获取所有键值的过程中，特殊语法 `%()s` 会被应用，其中 `` 可以是相同分区或者默认分区下的键名。字符串 `%()s` 会被相应的键值所替代，如果指定的键不存在，则会用空字符串替代。您可以最多使用 99 层的递归嵌套。 + +```ini +NAME = ini + +[author] +NAME = Unknwon +GITHUB

+cfg.Section("package").Key("FULL_NAME").String() // github.com/go-ini/ini +``` + +### 读取父子分区 + +您可以在分区名称中使用 `.` 来表示两个或多个分区之间的父子关系。如果某个键在子分区中不存在，则会去它的父分区中再次寻找，直到没有父分区为止。 + +```ini +NAME = ini +VERSION

`LoadOptions.UnparsableSections` 进行处理： + +```go +cfg, err := LoadSources(LoadOptions{UnparseableSections: []string{"COMMENTS"}}, `[COMMENTS] +<1> This slide has the fuel listed in the wrong units `)) + +body := cfg.Section("COMMENTS").Body() + +/* --- start --- +<1> This slide has the fuel listed in the wrong units +------ end --- */ +``` + +### 读取自增键名 + +如果数据源中的键名为 `-`，则认为该键使用了自增键名的特殊语法。计数器从 1 开始，并且分区之间是相互独立的。 + +```ini +[features] +-: Support read/write comments of keys and sections +-: Support auto-increment of key names +-: Support load multiple files to overwrite key values +``` + +```go +cfg.Section("features").KeyStrings() // []{"#1", "#2", "#3"} +``` + +### 映射到结构 + +想要使用更加面向对象的方式玩转 INI 吗？好主意。 + +```ini +Name = Unknwon +age = 21 +Male = true +Born = 1993-01-01T20:17:05Z +

err = ini.MapTo(p, "path/to/ini") + // ... + + // 嗯哼？只需要映射一个分区吗？ + n := new(Note) + err = cfg.Section("Note").MapTo(n) + // ... +} +``` + +结构的字段怎么设置默认值呢？很简单，只要在映射之前对指定字段进行赋值就可以了。如果键未找到或者类型错误，该值不会发生改变。 + +```go +// ... +p := &Person{ + Name: "Joe", +} +// ... +``` + +这样玩 INI 真的好酷啊！然而，如果不能还给我原来的配置文件，有什么卵用？ + +### 从结构反射 + +可是，我有说不能吗？ + +```go +type Embeded struct { + Dates []time.Time `delim:"|"` +

+- `AllCapsUnderscore`：该映射器将字段名转换至格式 `ALL_CAPS_UNDERSCORE` 后再去匹配分区名和键名。 +- `TitleUnderscore`：该映射器将字段名转换至格式 `title_underscore` 后再去匹配分区名和键名。 + +使用方法： + +```go +type Info struct{ + PackageName string +} + +func main() { + err = ini.MapToWithMapper(&Info{}, ini.TitleUnderscore, []byte("package_name=ini")) + // ... + + cfg, err := ini.Load([]byte("PACKAGE_NAME=ini")) + // ... + info := new(Info) + cfg.NameMapper = ini.AllCapsUnderscore + err = cfg.MapTo(info) + // ... +} +``` + +使用函数 `ini.ReflectFromWithMapper` 时也可应用相同的规则。 + +#### 值映射器（Value Mapper） + +值映射器允许使用一个自定义函数自动展开值的具体内容，例如：运行时获取环境变量： + +```go +type Env struct { + Foo string `ini:"foo"` +} + +func main() { + cfg, err := ini.Load([]byte("[env]\nfoo = ${MY_VAR}\n") + cfg.ValueMapper = os.ExpandEnv + // ... + env := &Env{} + err = cfg.Section("env").MapTo(env) +} +``` + +本例中，`env.Foo` 将会是运行时所获取到环境变量 `MY_VAR` 的值。 + +#### 映射/反射的其它说明 + +任何嵌入的结构都会被默认认作一个不同的分区，并且不会自动产生所谓的父子分区关联： + +```go +type Child struct { + Age string +} + +type Parent struct { + Name string + Child +} + +type Config struct { + City string + Parent +} +``` + +示例配置文件： + +```ini +City = Boston + +[Parent] +Name = Unknwon + +[Child] +Age = 21 +``` + +很好，但是，我就是要嵌入结构也在同一个分区。好吧，你爹是李刚！ + +```go +type Child struct { + Age string +} + +type Parent struct { + Name string + Child `ini:"Parent"` +} + +type Config struct { + City string + Parent +} +``` + +示例配置文件： + +```ini +City = Boston + +[Parent] +Name = Unknwon +Age = 21 +``` + +## 获取帮助 + +- [API 文档](https://gowalker.org/gopkg.in/ini.v1) +- [创建工单](https://github.com/go-ini/ini/issues/new) + +##

The problem +with this pattern is that you completely lose the original `error` structure. + +Arguably the _correct_ approach is that you should make a custom structure +implementing the `error` interface, and have the original error as a field +on that structure, such [as this example](http://golang.org/pkg/os/#PathError). +This is a good approach, but you have to know the entire chain of possible +rewrapping that happens, when you might just care about one. + +`errwrap` formalizes this pattern (it doesn't matter what approach you use +above) by giving a single interface for wrapping errors, checking if a specific +error is wrapped, and extracting that error. + +## Installation and Docs + +Install using `go get github.com/hashicorp/errwrap`. + +Full documentation is available at +http://godoc.org/github.com/hashicorp/errwrap + +## Usage + +#### Basic Usage + +Below is a very basic example of its usage: + +```go +// A function that always returns an error, but wraps it, like a real +// function might. +func tryOpen() error { + _, err := os.Open("/i/dont/exist") + if err != nil { + return errwrap.Wrapf("Doesn't exist: {{err}}", err) + } + + return nil +} + +func main() { + err := tryOpen() + + // We can use the Contains helpers to check if an error contains + // another error. It is safe to do this with a nil error, or with + // an error that doesn't even use the errwrap package. + if errwrap.Contains(err, ErrNotExist) { + // Do something + } + if errwrap.ContainsType(err, new(os.PathError)) { + // Do something + } + + // Or we can use the associated `Get` functions to just extract + // a specific error. This would return nil if that specific error doesn't + // exist. + perr := errwrap.GetType(err, new(os.PathError)) +} +``` + +#### Custom Types + +If you're already making custom types that properly wrap errors, then +you can get all the functionality of `errwraps.Contains` and such by +implementing the `Wrapper` interface with just one function. Example: + +```go +type AppError { + Code ErrorCode + Err error +} + +func (e *AppError) WrappedErrors() []error { + return []error{e.Err} +} +``` + +Now this works: + +```go +err := &AppError{Err: fmt.Errorf("an error")} +if errwrap.ContainsType(err, fmt.Errorf("")) { + // This will work! +} +``` diff --git a/vendor/github.com/hashicorp/errwrap/errwrap.go b/vendor/github.com/hashicorp/errwrap/errwrap.go new file mode 100644 index 0000000..a733bef --- /dev/null +++ b/vendor/github.com/hashicorp/errwrap/errwrap.go @@ -0,0 +1,169 @@ +// Package errwrap implements methods to formalize error wrapping in Go. +// +// All of the top-level functions that take an `error` are built to be able +// to take any error, not just wrapped errors.

This removes the burden of knowing how to +download from a variety of sources from the implementer. + +The concept of a _detector_ automatically turns invalid URLs into proper +URLs. For example: "github.com/hashicorp/go-getter" would turn into a +Git URL. Or "./foo" would turn into a file URL. These are extensible. + +This library is used by [Terraform](https://terraform.io) for +downloading modules, [Otto](https://ottoproject.io) for dependencies and +Appfile imports, and [Nomad](https://nomadproject.io) for downloading +binaries. + +## Installation and Usage + +Package documentation can be found on +[GoDoc](http://godoc.org/github.com/hashicorp/go-getter). + +Installation can be done with a normal `go get`: + +``` +$ go get github.com/hashicorp/go-getter +``` + +go-getter also has a command you can use to test URL strings: + +``` +$ go install github.com/hashicorp/go-getter/cmd/go-getter +... + +$ go-getter github.com/foo/bar ./foo +... +``` + +The command is useful for verifying URL structures. + +## URL Format + +go-getter uses a single string URL as input to download from a variety of +protocols. go-getter has various "tricks" with this URL to do certain things. +This section documents the URL format. + +### Supported Protocols and Detectors + +**Protocols** are used to download files/directories using a specific +mechanism. Example protocols are Git and HTTP. + +**Detectors** are used to transform a valid or invalid URL into another +URL if it matches a certain pattern. Example: "github.com/user/repo" is +automatically transformed into a fully valid Git URL. This allows go-getter +to be very user friendly. + +go-getter out of the box supports the following protocols. Additional protocols +can be augmented at runtime by implementing the `Getter` interface. + + * Local files + * Git + * Mercurial + * HTTP + * Amazon S3 + +In addition to the above protocols, go-getter has what are called "detectors." +These take a URL and attempt to automatically choose the best protocol for +it, which might involve even changing the protocol. The following detection +is built-in by default: + + * File paths such as "./foo" are automatically changed to absolute + file URLs. + * GitHub URLs, such as "github.com/mitchellh/vagrant" are automatically + changed to Git protocol over HTTP. + * BitBucket URLs, such as "bitbucket.org/mitchellh/vagrant" are automatically + changed to a Git or mercurial protocol using the BitBucket API. + +### Forced Protocol + +In some cases, the protocol to use is ambiguous depending on the source +URL. For example, "http://github.com/mitchellh/vagrant.git" could reference +an HTTP URL or a Git URL. Forced protocol syntax is used to disambiguate this +URL. + +Forced protocol can be done by prefixing the URL with the protocol followed +by double colons. For example: `git::http://github.com/mitchellh/vagrant.git` +would download the given HTTP URL using the Git protocol. + +Forced protocols will also override any detectors. + +In the absense of a forced protocol, detectors may be run on the URL, transforming +the protocol anyways. The above example would've used the Git protocol either +way since the Git detector would've detected it was a GitHub URL. + +### Protocol-Specific Options + +Each protocol can support protocol-specific options to configure that +protocol. For example, the `git` protocol supports specifying a `ref` +query parameter that tells it what ref to checkout for that Git +repository. + +The options are specified as query parameters on the URL (or URL-like string) +given to go-getter. Using the Git example above, the URL below is a valid +input to go-getter: + + github.com/hashicorp/go-getter?ref=abcd1234 + +The protocol-specific options are documented below the URL format +section. But because they are part of the URL, we point it out here so +you know they exist. + +### Checksumming + +For file downloads of any protocol, go-getter can automatically verify +a checksum for you. Note that checksumming only works for downloading files, +not directories, but checksumming will work for any protocol. + +To checksum a file, append a `checksum` query parameter to the URL. +The paramter value should be in the format of `type:value`, where +type is "md5", "sha1", "sha256", or "sha512". The "value" should be +the actual checksum value. go-getter will parse out this query parameter +automatically and use it to verify the checksum. An example URL +is shown below: + +``` +./foo.txt?checksum=md5:b7d96c89d09d9e204f5fedc4d5d55b21 +``` + +The checksum query parameter is never sent to the backend protocol +implementation. It is used at a higher level by go-getter itself. + +### Unarchiving + +go-getter will automatically unarchive files into a file or directory +based on the extension of the file being requested (over any protocol). +This works for both file and directory downloads. + +go-getter looks for an `archive` query parameter to specify the format of +the archive. If this isn't specified, go-getter will use the extension of +the path to see if it appears archived. Unarchiving can be explicitly +disabled by setting the `archive` query parameter to `false`. + +The following archive formats are supported: + + * `tar.gz` and `tgz` + * `tar.bz2` and `tbz2` + * `zip` + * `gz` + * `bz2` + +For example, an example URL is shown below: + +``` +./foo.zip +``` + +This will automatically be inferred to be a ZIP file and will be extracted. +You can also be explicit about the archive type: + +``` +./some/other/path?archive=zip +``` + +And finally, you can disable archiving completely: + +``` +./some/path?archive=false +``` + +You can combine unarchiving with the other features of go-getter such +as checksumming. The special `archive` query parameter will be removed +from the URL before going to the final protocol downloader. + +## Protocol-Specific Options + +This section documents the protocol-specific options that can be specified +for go-getter. These options should be appended to the input as normal query +parameters. Depending on the usage of go-getter, applications may provide +alternate ways of inputting options. For example, [Nomad](https://www.nomadproject.io) +provides a nice options block for specifying options rather than in the URL. + +## General (All Protocols) + +The options below are available to all protocols: + + * `archive` - The archive format to use to unarchive this file, or "" (empty + string) to disable unarchiving. For more details, see the complete section + on archive support above. + + * `checksum` - Checksum to verify the downloaded file or archive. See + the entire section on checksumming above for format and more details. + +### Local Files (`file`) + +None + +### Git (`git`) + + * `ref` - The Git ref to checkout. This is a ref, so it can point to + a commit SHA, a branch name, etc. If it is a named ref such as a branch + name, go-getter will update it to the latest on each get. + + * `sshkey` - An SSH private key to use during clones. The provided key must + be a base64-encoded string. For example, to generate a suitable `sshkey` + from a private key file on disk, you would run `base64 -w0 `. + + **Note**: Git 2.3+ is required to use this feature. + +### Mercurial (`hg`) + + * `rev` - The Mercurial revision to checkout. + +### HTTP (`http`) + +None + +### S3 (`s3`) + +S3 takes various access configurations in the URL. Note that it will also +read these from standard AWS environment variables if they're set. If +the query parameters are present, these take priority. + + * `aws_access_key_id` - AWS access key. + * `aws_access_key_secret` - AWS access key secret. + * `aws_access_token` - AWS access token if this is being used. + +#### Using IAM Instance Profiles with S3 + +If you use go-getter and want to use an EC2 IAM Instance Profile to avoid +using credentials, then just omit these and the profile, if available will +be used automatically. + +#### S3 Bucket Examples + +S3 has several addressing schemes used to reference your bucket.

It is the plugin system +that has been in use by HashiCorp tooling for over 3 years. While initially +created for [Packer](https://www.packer.io), it has since been used by +[Terraform](https://www.terraform.io) and [Otto](https://www.ottoproject.io), +with plans to also use it for [Nomad](https://www.nomadproject.io) and +[Vault](https://www.vaultproject.io). + +While the plugin system is over RPC, it is currently only designed to work +over a local [reliable] network. Plugins over a real network are not supported +and will lead to unexpected behavior. + +This plugin system has been used on millions of machines across many different +projects and has proven to be battle hardened and ready for production use. + +## Features + +The HashiCorp plugin system supports a number of features: + +**Plugins are Go interface implementations.** This makes writing and consuming +plugins feel very natural. To a plugin author: you just implement an +interface as if it were going to run in the same process. For a plugin user: +you just use and call functions on an interface as if it were in the same +process. This plugin system handles the communication in between. + +**Complex arguments and return values are supported.** This library +provides APIs for handling complex arguments and return values such +as interfaces, `io.Reader/Writer`, etc. We do this by giving you a library +(`MuxBroker`) for creating new connections between the client/server to +serve additional interfaces or transfer raw data. + +**Bidirectional communication.** Because the plugin system supports +complex arguments, the host process can send it interface implementations +and the plugin can call back into the host process. + +**Built-in Logging.** Any plugins that use the `log` standard library +will have log data automatically sent to the host process. The host +process will mirror this output prefixed with the path to the plugin +binary. This makes debugging with plugins simple. + +**Protocol Versioning.** A very basic "protocol version" is supported that +can be incremented to invalidate any previous plugins. This is useful when +interface signatures are changing, protocol level changes are necessary, +etc. When a protocol version is incompatible, a human friendly error +message is shown to the end user. + +**Stdout/Stderr Syncing.** While plugins are subprocesses, they can continue +to use stdout/stderr as usual and the output will get mirrored back to +the host process. The host process can control what `io.Writer` these +streams go to to prevent this from happening. + +**TTY Preservation.** Plugin subprocesses are connected to the identical +stdin file descriptor as the host process, allowing software that requires +a TTY to work. For example, a plugin can execute `ssh` and even though there +are multiple subprocesses and RPC happening, it will look and act perfectly +to the end user. + +**Host upgrade while a plugin is running.** Plugins can be "reattached" +so that the host process can be upgraded while the plugin is still running. +This requires the host/plugin to know this is possible and daemonize +properly. `NewClient` takes a `ReattachConfig` to determine if and how to +reattach. + +## Architecture + +The HashiCorp plugin system works by launching subprocesses and communicating +over RPC (using standard `net/rpc`). A single connection is made between +any plugin and the host process, and we use a +[connection multiplexing](https://github.com/hashicorp/yamux) +library to multiplex any other connections on top. + +This architecture has a number of benefits: + + * Plugins can't crash your host process: A panic in a plugin doesn't + panic the plugin user. + + * Plugins are very easy to write: just write a Go application and `go build`. + Theoretically you could also use another language as long as it can + communicate the Go `net/rpc` protocol but this hasn't yet been tried. + + * Plugins are very easy to install: just put the binary in a location where + the host will find it (depends on the host but this library also provides + helpers), and the plugin host handles the rest. + + * Plugins can be relatively secure: The plugin only has access to the + interfaces and args given to it, not to the entire memory space of the + process. More security features are planned (see the coming soon section + below). + +## Usage + +To use the plugin system, you must take the following steps. These are +high-level steps that must be done. Examples are available in the +`examples/` directory. + + 1. Choose the interface(s) you want to expose for plugins. + + 2. For each interface, implement an implementation of that interface + that communicates over an `*rpc.Client` (from the standard `net/rpc` + package) for every function call. Likewise, implement the RPC server + struct this communicates to which is then communicating to a real, + concrete implementation. + + 3. Create a `Plugin` implementation that knows how to create the RPC + client/server for a given plugin type. + + 4. Plugin authors call `plugin.Serve` to serve a plugin from the + `main` function. + + 5. Plugin users use `plugin.Client` to launch a subprocess and request + an interface implementation over RPC. + +That's it! In practice, step 2 is the most tedious and time consuming step. +Even so, it isn't very difficult and you can see examples in the `examples/` +directory as well as throughout our various open source projects. + +For complete API documentation, see [GoDoc](https://godoc.org/github.com/hashicorp/go-plugin). + +## Roadmap + +Our plugin system is constantly evolving. As we use the plugin system for +new projects or for new features in existing projects, we constantly find +improvements we can make. + +At this point in time, the roadmap for the plugin system is: + +**Cryptographically Secure Plugins.** We'll implement signing plugins +and loading signed plugins in order to allow Vault to make use of multi-process +in a secure way. + +**Semantic Versioning.** Plugins will be able to implement a semantic version. +This plugin system will give host processes a system for constraining +versions. This is in addition to the protocol versioning already present +which is more for larger underlying changes. + +**Plugin fetching.** We will integrate with [go-getter](https://github.com/hashicorp/go-getter) +to support automatic download + install of plugins. Paired with cryptographically +secure plugins (above), we can make this a safe operation for an amazing +user experience. + +## What About Shared Libraries? + +When we started using plugins (late 2012, early 2013), plugins over RPC +were the only option since Go didn't support dynamic library loading. Today, +Go still doesn't support dynamic library loading, but they do intend to. +Since 2012, our plugin system has stabilized from millions of users using it, +and has many benefits we've come to value greatly. + +For example, we intend to use this plugin system in +[Vault](https://www.vaultproject.io), and dynamic library loading will +simply never be acceptable in Vault for security reasons. That is an extreme +example, but we believe our library system has more upsides than downsides +over dynamic library loading and since we've had it built and tested for years, +we'll likely continue to use it. + +Shared libraries have one major advantage over our system which is much +higher performance. In real world scenarios across our various tools, +we've never required any more performance out of our plugin system and it +has seen very high throughput, so this isn't a concern for us at the moment. + diff --git a/vendor/github.com/hashicorp/go-plugin/client.go b/vendor/github.com/hashicorp/go-plugin/client.go new file mode 100644 index 0000000..9f8a0f2 --- /dev/null +++ b/vendor/github.com/hashicorp/go-plugin/client.go @@ -0,0 +1,581 @@ +package plugin + +import ( + "bufio" + "errors" + "fmt" + "io" + "io/ioutil" + "log" + "net" + "os" + "os/exec" + "path/filepath" + "strconv" + "strings" + "sync" + "sync/atomic" + "time" + "unicode" +) + +// If this is 1, then we've called CleanupClients.

No additional rights or licenses will be implied from the + distribution or licensing of Covered Software under this License. + Notwithstanding Section 2.1(b) above, no patent license is granted by a + Contributor: + + a. for any code that a Contributor has removed from Covered Software; or + + b. for infringements caused by: (i) Your and any other third party's + modifications of Covered Software, or (ii) the combination of its + Contributions with other software (except as part of its Contributor + Version); or + + c. under Patent Claims infringed by Covered Software in the absence of + its Contributions. + + This License does not grant any rights in the trademarks, service marks, + or logos of any Contributor (except as may be necessary to comply with + the notice requirements in Section 3.4). + +2.4. Subsequent Licenses + + No Contributor makes additional grants as a result of Your choice to + distribute the Covered Software under a subsequent version of this + License (see Section 10.2) or under the terms of a Secondary License (if + permitted under the terms of Section 3.3). + +2.5.

Fair Use + + This License is not intended to limit any rights You have under + applicable copyright doctrines of fair use, fair dealing, or other + equivalents. + +2.7. Conditions + + Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in + Section 2.1. + + +3. Responsibilities + +3.1. Distribution of Source Form + + All distribution of Covered Software in Source Code Form, including any + Modifications that You create or to which You contribute, must be under + the terms of this License. You must inform recipients that the Source + Code Form of the Covered Software is governed by the terms of this + License, and how they can obtain a copy of this License. You may not + attempt to alter or restrict the recipients' rights in the Source Code + Form. + +3.2. Distribution of Executable Form + + If You distribute Covered Software in Executable Form then: + + a. such Covered Software must also be made available in Source Code Form, + as described in Section 3.1, and You must inform recipients of the + Executable Form how they can obtain a copy of such Source Code Form by + reasonable means in a timely manner, at a charge no more than the cost + of distribution to the recipient; and + + b. You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter the + recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + + You may create and distribute a Larger Work under terms of Your choice, + provided that You also comply with the requirements of this License for + the Covered Software. If the Larger Work is a combination of Covered + Software with a work governed by one or more Secondary Licenses, and the + Covered Software is not Incompatible With Secondary Licenses, this + License permits You to additionally distribute such Covered Software + under the terms of such Secondary License(s), so that the recipient of + the Larger Work may, at their option, further distribute the Covered + Software under the terms of either this License or such Secondary + License(s). + +3.4. Notices + + You may not remove or alter the substance of any license notices + (including copyright notices, patent notices, disclaimers of warranty, or + limitations of liability) contained within the Source Code Form of the + Covered Software, except that You may alter any license notices to the + extent required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + + You may choose to offer, and to charge a fee for, warranty, support, + indemnity or liability obligations to one or more recipients of Covered + Software. However, You may do so only on Your own behalf, and not on + behalf of any Contributor. You must make it absolutely clear that any + such warranty, support, indemnity, or liability obligation is offered by + You alone, and You hereby agree to indemnify every Contributor for any + liability incurred by such Contributor as a result of warranty, support, + indemnity or liability terms You offer. You may include additional + disclaimers of warranty and limitations of liability specific to any + jurisdiction. + +4. Inability to Comply Due to Statute or Regulation + + If it is impossible for You to comply with any of the terms of this License + with respect to some or all of the Covered Software due to statute, + judicial order, or regulation then You must: (a) comply with the terms of + this License to the maximum extent possible; and (b) describe the + limitations and the code they affect. Such description must be placed in a + text file included with all distributions of the Covered Software under + this License. Except to the extent prohibited by statute or regulation, + such description must be sufficiently detailed for a recipient of ordinary + skill to be able to understand it. + +5. Termination + +5.1. The rights granted under this License will terminate automatically if You + fail to comply with any of its terms. However, if You become compliant, + then the rights granted under this License from a particular Contributor + are reinstated (a) provisionally, unless and until such Contributor + explicitly and finally terminates Your grants, and (b) on an ongoing + basis, if such Contributor fails to notify You of the non-compliance by + some reasonable means prior to 60 days after You have come back into + compliance. Moreover, Your grants from a particular Contributor are + reinstated on an ongoing basis if such Contributor notifies You of the + non-compliance by some reasonable means, this is the first time You have + received notice of non-compliance with this License from such + Contributor, and You become compliant prior to 30 days after Your receipt + of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent + infringement claim (excluding declaratory judgment actions, + counter-claims, and cross-claims) alleging that a Contributor Version + directly or indirectly infringes any patent, then the rights granted to + You by any and all Contributors for the Covered Software under Section + 2.1 of this License shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user + license agreements (excluding distributors and resellers) which have been + validly granted by You or Your distributors under this License prior to + termination shall survive termination. + +6. Disclaimer of Warranty + + Covered Software is provided under this License on an "as is" basis, + without warranty of any kind, either expressed, implied, or statutory, + including, without limitation, warranties that the Covered Software is free + of defects, merchantable, fit for a particular purpose or non-infringing. + The entire risk as to the quality and performance of the Covered Software + is with You. Should any Covered Software prove defective in any respect, + You (not any Contributor) assume the cost of any necessary servicing, + repair, or correction. This disclaimer of warranty constitutes an essential + part of this License. No use of any Covered Software is authorized under + this License except under this disclaimer. + +7. Limitation of Liability + + Under no circumstances and under no legal theory, whether tort (including + negligence), contract, or otherwise, shall any Contributor, or anyone who + distributes Covered Software as permitted above, be liable to You for any + direct, indirect, special, incidental, or consequential damages of any + character including, without limitation, damages for lost profits, loss of + goodwill, work stoppage, computer failure or malfunction, or any and all + other commercial damages or losses, even if such party shall have been + informed of the possibility of such damages. This limitation of liability + shall not apply to liability for death or personal injury resulting from + such party's negligence to the extent applicable law prohibits such + limitation. Some jurisdictions do not allow the exclusion or limitation of + incidental or consequential damages, so this exclusion and limitation may + not apply to You. + +8. Litigation + + Any litigation relating to this License may be brought only in the courts + of a jurisdiction where the defendant maintains its principal place of + business and such litigation shall be governed by laws of that + jurisdiction, without reference to its conflict-of-law provisions. Nothing + in this Section shall prevent a party's ability to bring cross-claims or + counter-claims. + +9. Miscellaneous + + This License represents the complete agreement concerning the subject + matter hereof. If any provision of this License is held to be + unenforceable, such provision shall be reformed only to the extent + necessary to make it enforceable. Any law or regulation which provides that + the language of a contract shall be construed against the drafter shall not + be used to construe this License against a Contributor. + + +10. Versions of the License + +10.1. New Versions + + Mozilla Foundation is the license steward. Except as provided in Section + 10.3, no one other than the license steward has the right to modify or + publish new versions of this License. Each version will be given a + distinguishing version number. + +10.2. Effect of New Versions + + You may distribute the Covered Software under the terms of the version + of the License under which You originally received the Covered Software, + or under the terms of any subsequent version published by the license + steward. + +10.3. Modified Versions + + If you create software not governed by this License, and you want to + create a new license for such software, you may create and use a + modified version of this License if you rename the license and remove + any references to the name of the license steward (except to note that + such modified license differs from this License). + +10.4.

With YAML, we found that beginners +had a really hard time determining what the actual structure was, and +ended up guessing more often than not whether to use a hyphen, colon, etc. +in order to represent some configuration key. + +Full programming languages such as Ruby enable complex behavior +a configuration language shouldn't usually allow, and also forces +people to learn some set of Ruby. + +Because of this, we decided to create our own configuration language +that is JSON-compatible. Our configuration language (HCL) is designed +to be written and modified by humans. The API for HCL allows JSON +as an input so that it is also machine-friendly (machines can generate +JSON instead of trying to generate HCL). + +Our goal with HCL is not to alienate other configuration languages. +It is instead to provide HCL as a specialized language for our tools, +and JSON as the interoperability layer. + +## Syntax + +For a complete grammar, please see the parser itself. A high-level overview +of the syntax and grammar is listed here. + + * Single line comments start with `#` or `//` + + * Multi-line comments are wrapped in `/*` and `*/`. Nested block comments + are not allowed. A multi-line comment (also known as a block comment) + terminates at the first `*/` found. + + * Values are assigned with the syntax `key = value` (whitespace doesn't + matter). The value can be any primitive: a string, number, boolean, + object, or list. + + * Strings are double-quoted and can contain any UTF-8 characters. + Example: `"Hello, World"` + + * Multi-line strings start with `<- + echo %Path% + + go version + + go env + + go get -t ./... + +build_script: +- cmd: go test -v ./... diff --git a/vendor/github.com/hashicorp/hcl/decoder.go b/vendor/github.com/hashicorp/hcl/decoder.go new file mode 100644 index 0000000..0b39c1b --- /dev/null +++ b/vendor/github.com/hashicorp/hcl/decoder.go @@ -0,0 +1,724 @@ +package hcl + +import ( + "errors" + "fmt" + "reflect" + "sort" + "strconv" + "strings" + + "github.com/hashicorp/hcl/hcl/ast" + "github.com/hashicorp/hcl/hcl/parser" + "github.com/hashicorp/hcl/hcl/token" +) + +// This is the tag to use with structures to have settings for HCL +const tagName = "hcl" + +var ( + // nodeType holds a reference to the type of ast.Node + nodeType reflect.Type = findNodeType() +) + +// Unmarshal accepts a byte slice as input and writes the +// data to the value pointed to by v. +func Unmarshal(bs []byte, v interface{}) error { + root, err := parse(bs) + if err != nil { + return err + } + + return DecodeObject(v, root) +} + +// Decode reads the given input and decodes it into the structure +// given by `out`. +func Decode(out interface{}, in string) error { + obj, err := Parse(in) + if err != nil { + return err + } + + return DecodeObject(out, obj) +} + +// DecodeObject is a lower-level version of Decode.

The goal of HIL is to make a simple +language for interpolations in the various configurations of HashiCorp tools. + +HIL is built to interpolate any string, but is in use by HashiCorp primarily +with [HCL](https://github.com/hashicorp/hcl). HCL is _not required_ in any +way for use with HIL. + +HIL isn't meant to be a general purpose language. It was built for basic +configuration interpolations. Therefore, you can't currently write functions, +have conditionals, set intermediary variables, etc. within HIL itself. It is +possible some of these may be added later but the right use case must exist. + +## Why? + +Many of our tools have support for something similar to templates, but +within the configuration itself. The most prominent requirement was in +[Terraform](https://github.com/hashicorp/terraform) where we wanted the +configuration to be able to reference values from elsewhere in the +configuration. Example: + + foo = "hi ${var.world}" + +We originally used a full templating language for this, but found it +was too heavy weight. Additionally, many full languages required bindings +to C (and thus the usage of cgo) which we try to avoid to make cross-compilation +easier. We then moved to very basic regular expression based +string replacement, but found the need for basic arithmetic and function +calls resulting in overly complex regular expressions. + +Ultimately, we wrote our own mini-language within Terraform itself. As +we built other projects such as [Nomad](https://nomadproject.io) and +[Otto](https://ottoproject.io), the need for basic interpolations arose +again. + +Thus HIL was born. It is extracted from Terraform, cleaned up, and +better tested for general purpose use. + +## Syntax + +For a complete grammar, please see the parser itself. A high-level overview +of the syntax and grammer is listed here. + +Code begins within `${` and `}`. Outside of this, text is treated +literally. For example, `foo` is a valid HIL program that is just the +string "foo", but `foo ${bar}` is an HIL program that is the string "foo " +concatened with the value of `bar`. For the remainder of the syntax +docs, we'll assume you're within `${}`. + + * Identifiers are any text in the format of `[a-zA-Z0-9-.]`. Example + identifiers: `foo`, `var.foo`, `foo-bar`. + + * Strings are double quoted and can contain any UTF-8 characters. + Example: `"Hello, World"` + + * Numbers are assumed to be base 10. If you prefix a number with 0x, + it is treated as a hexadecimal. If it is prefixed with 0, it is + treated as an octal. Numbers can be in scientific notation: "1e10". + + * Unary `-` can be used for negative numbers. Example: `-10` or `-0.2` + + * Boolean values: `true`, `false` + + * The following arithmetic operations are allowed: +, -, *, /, %. + + * Function calls are in the form of `name(arg1, arg2, ...)`. Example: + `add(1, 5)`. Arguments can be any valid HIL expression, example: + `add(1, var.foo)` or even nested function calls: + `add(1, get("some value"))`. + + * Within strings, further interpolations can be opened with `${}`. + Example: `"Hello ${nested}"`. A full example including the + original `${}` (remember this list assumes were inside of one + already) could be: `foo ${func("hello ${var.foo}")}`. + +## Language Changes + +We've used this mini-language in Terraform for years. For backwards compatibility +reasons, we're unlikely to make an incompatible change to the language but +we're not currently making that promise, either. + +The internal API of this project may very well change as we evolve it +to work with more of our projects. We recommend using some sort of dependency +management solution with this package. + +## Future Changes + +The following changes are already planned to be made at some point: + + * Richer types: lists, maps, etc. + + * Convert to a more standard Go parser structure similar to HCL. This + will improve our error messaging as well as allow us to have automatic + formatting. + + * Allow interpolations to result in more types than just a string. While + within the interpolation basic types are honored, the result is always + a string. diff --git a/vendor/github.com/hashicorp/hil/appveyor.yml b/vendor/github.com/hashicorp/hil/appveyor.yml new file mode 100644 index 0000000..feaf7a3 --- /dev/null +++ b/vendor/github.com/hashicorp/hil/appveyor.yml @@ -0,0 +1,18 @@ +version: "build-{branch}-{build}" +image: Visual Studio 2015 +clone_folder: c:\gopath\src\github.com\hashicorp\hil +environment: + GOPATH: c:\gopath +init: + - git config --global core.autocrlf true +install: +- cmd: >- + echo %Path% + + go version + + go env + + go get -d -v -t ./... +build_script: +- cmd: go test -v ./... diff --git a/vendor/github.com/hashicorp/hil/ast/arithmetic.go b/vendor/github.com/hashicorp/hil/ast/arithmetic.go new file mode 100644 index 0000000..94dc24f --- /dev/null +++ b/vendor/github.com/hashicorp/hil/ast/arithmetic.go @@ -0,0 +1,43 @@ +package ast + +import ( + "bytes" + "fmt" +) + +// Arithmetic represents a node where the result is arithmetic of +// two or more operands in the order given. +type Arithmetic struct { + Op ArithmeticOp + Exprs []Node + Posx Pos +} + +func (n *Arithmetic) Accept(v Visitor) Node { + for i, expr := range n.Exprs { + n.Exprs[i] = expr.Accept(v) + } + + return v(n) +} + +func (n *Arithmetic) Pos() Pos { + return n.Posx +} + +func (n *Arithmetic) GoString() string { + return fmt.Sprintf("*%#v", *n) +} + +func (n *Arithmetic) String() string { + var b bytes.Buffer + for _, expr := range n.Exprs { + b.WriteString(fmt.Sprintf("%s", expr)) + } + + return b.String() +} + +func (n *Arithmetic) Type(Scope) (Type, error) { + return TypeInt, nil +} diff --git a/vendor/github.com/hashicorp/hil/ast/arithmetic_op.go b/vendor/github.com/hashicorp/hil/ast/arithmetic_op.go new file mode 100644 index 0000000..18880c6 --- /dev/null +++ b/vendor/github.com/hashicorp/hil/ast/arithmetic_op.go @@ -0,0 +1,24 @@ +package ast + +// ArithmeticOp is the operation to use for the math. +type ArithmeticOp int + +const ( + ArithmeticOpInvalid ArithmeticOp = 0 + + ArithmeticOpAdd ArithmeticOp = iota + ArithmeticOpSub + ArithmeticOpMul + ArithmeticOpDiv + ArithmeticOpMod + + ArithmeticOpLogicalAnd + ArithmeticOpLogicalOr + + ArithmeticOpEqual + ArithmeticOpNotEqual + ArithmeticOpLessThan + ArithmeticOpLessThanOrEqual + ArithmeticOpGreaterThan + ArithmeticOpGreaterThanOrEqual +) diff --git a/vendor/github.com/hashicorp/hil/ast/ast.go b/vendor/github.com/hashicorp/hil/ast/ast.go new file mode 100644 index 0000000..c6350f8 --- /dev/null +++ b/vendor/github.com/hashicorp/hil/ast/ast.go @@ -0,0 +1,99 @@ +package ast + +import ( + "fmt" +) + +// Node is the interface that all AST nodes must implement. +type Node interface { + // Accept is called to dispatch to the visitors.

Effective Date + + The licenses granted in Section 2.1 with respect to any Contribution become + effective for each Contribution on the date the Contributor first distributes + such Contribution. + +2.3. Limitations on Grant Scope + + The licenses granted in this Section 2 are the only rights granted under this + License.

Conditions + + Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in + Section 2.1. + + +3. Responsibilities + +3.1. Distribution of Source Form + + All distribution of Covered Software in Source Code Form, including any + Modifications that You create or to which You contribute, must be under the + terms of this License. You must inform recipients that the Source Code Form + of the Covered Software is governed by the terms of this License, and how + they can obtain a copy of this License. You may not attempt to alter or + restrict the recipients’ rights in the Source Code Form. + +3.2. Distribution of Executable Form + + If You distribute Covered Software in Executable Form then: + + a. such Covered Software must also be made available in Source Code Form, + as described in Section 3.1, and You must inform recipients of the + Executable Form how they can obtain a copy of such Source Code Form by + reasonable means in a timely manner, at a charge no more than the cost + of distribution to the recipient; and + + b. You may distribute such Executable Form under the terms of this License, + or sublicense it under different terms, provided that the license for + the Executable Form does not attempt to limit or alter the recipients’ + rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + + You may create and distribute a Larger Work under terms of Your choice, + provided that You also comply with the requirements of this License for the + Covered Software. If the Larger Work is a combination of Covered Software + with a work governed by one or more Secondary Licenses, and the Covered + Software is not Incompatible With Secondary Licenses, this License permits + You to additionally distribute such Covered Software under the terms of + such Secondary License(s), so that the recipient of the Larger Work may, at + their option, further distribute the Covered Software under the terms of + either this License or such Secondary License(s). + +3.4. Notices + + You may not remove or alter the substance of any license notices (including + copyright notices, patent notices, disclaimers of warranty, or limitations + of liability) contained within the Source Code Form of the Covered + Software, except that You may alter any license notices to the extent + required to remedy known factual inaccuracies. + +3.5. Application of Additional Terms + + You may choose to offer, and to charge a fee for, warranty, support, + indemnity or liability obligations to one or more recipients of Covered + Software. However, You may do so only on Your own behalf, and not on behalf + of any Contributor. You must make it absolutely clear that any such + warranty, support, indemnity, or liability obligation is offered by You + alone, and You hereby agree to indemnify every Contributor for any + liability incurred by such Contributor as a result of warranty, support, + indemnity or liability terms You offer. You may include additional + disclaimers of warranty and limitations of liability specific to any + jurisdiction. + +4. Inability to Comply Due to Statute or Regulation + + If it is impossible for You to comply with any of the terms of this License + with respect to some or all of the Covered Software due to statute, judicial + order, or regulation then You must: (a) comply with the terms of this License + to the maximum extent possible; and (b) describe the limitations and the code + they affect. Such description must be placed in a text file included with all + distributions of the Covered Software under this License. Except to the + extent prohibited by statute or regulation, such description must be + sufficiently detailed for a recipient of ordinary skill to be able to + understand it. + +5. Termination + +5.1. The rights granted under this License will terminate automatically if You + fail to comply with any of its terms. However, if You become compliant, + then the rights granted under this License from a particular Contributor + are reinstated (a) provisionally, unless and until such Contributor + explicitly and finally terminates Your grants, and (b) on an ongoing basis, + if such Contributor fails to notify You of the non-compliance by some + reasonable means prior to 60 days after You have come back into compliance. + Moreover, Your grants from a particular Contributor are reinstated on an + ongoing basis if such Contributor notifies You of the non-compliance by + some reasonable means, this is the first time You have received notice of + non-compliance with this License from such Contributor, and You become + compliant prior to 30 days after Your receipt of the notice. + +5.2. If You initiate litigation against any entity by asserting a patent + infringement claim (excluding declaratory judgment actions, counter-claims, + and cross-claims) alleging that a Contributor Version directly or + indirectly infringes any patent, then the rights granted to You by any and + all Contributors for the Covered Software under Section 2.1 of this License + shall terminate. + +5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user + license agreements (excluding distributors and resellers) which have been + validly granted by You or Your distributors under this License prior to + termination shall survive termination. + +6. Disclaimer of Warranty + + Covered Software is provided under this License on an “as is” basis, without + warranty of any kind, either expressed, implied, or statutory, including, + without limitation, warranties that the Covered Software is free of defects, + merchantable, fit for a particular purpose or non-infringing. The entire + risk as to the quality and performance of the Covered Software is with You. + Should any Covered Software prove defective in any respect, You (not any + Contributor) assume the cost of any necessary servicing, repair, or + correction. This disclaimer of warranty constitutes an essential part of this + License. No use of any Covered Software is authorized under this License + except under this disclaimer. + +7. Limitation of Liability + + Under no circumstances and under no legal theory, whether tort (including + negligence), contract, or otherwise, shall any Contributor, or anyone who + distributes Covered Software as permitted above, be liable to You for any + direct, indirect, special, incidental, or consequential damages of any + character including, without limitation, damages for lost profits, loss of + goodwill, work stoppage, computer failure or malfunction, or any and all + other commercial damages or losses, even if such party shall have been + informed of the possibility of such damages. This limitation of liability + shall not apply to liability for death or personal injury resulting from such + party’s negligence to the extent applicable law prohibits such limitation. + Some jurisdictions do not allow the exclusion or limitation of incidental or + consequential damages, so this exclusion and limitation may not apply to You. + +8. Litigation + + Any litigation relating to this License may be brought only in the courts of + a jurisdiction where the defendant maintains its principal place of business + and such litigation shall be governed by laws of that jurisdiction, without + reference to its conflict-of-law provisions. Nothing in this Section shall + prevent a party’s ability to bring cross-claims or counter-claims. + +9. Miscellaneous + + This License represents the complete agreement concerning the subject matter + hereof. If any provision of this License is held to be unenforceable, such + provision shall be reformed only to the extent necessary to make it + enforceable. Any law or regulation which provides that the language of a + contract shall be construed against the drafter shall not be used to construe + this License against a Contributor. + + +10. Versions of the License + +10.1. New Versions + + Mozilla Foundation is the license steward. Except as provided in Section + 10.3, no one other than the license steward has the right to modify or + publish new versions of this License. Each version will be given a + distinguishing version number. + +10.2.

This limitation of liability + shall not apply to liability for death or personal injury resulting from + such party's negligence to the extent applicable law prohibits such + limitation. Some jurisdictions do not allow the exclusion or limitation of + incidental or consequential damages, so this exclusion and limitation may + not apply to You. + +8. Litigation + + Any litigation relating to this License may be brought only in the courts + of a jurisdiction where the defendant maintains its principal place of + business and such litigation shall be governed by laws of that + jurisdiction, without reference to its conflict-of-law provisions.

Miscellaneous + + This License represents the complete agreement concerning the subject + matter hereof. If any provision of this License is held to be + unenforceable, such provision shall be reformed only to the extent + necessary to make it enforceable. Any law or regulation which provides that + the language of a contract shall be construed against the drafter shall not + be used to construe this License against a Contributor. + + +10.

Each +frame contains a header like: + +* Version (8 bits) +* Type (8 bits) +* Flags (16 bits) +* StreamID (32 bits) +* Length (32 bits) + +This means that each header has a 12 byte overhead. +All fields are encoded in network order (big endian). +Each field is described below: + +## Version Field + +The version field is used for future backward compatibility. At the +current time, the field is always set to 0, to indicate the initial +version. + +## Type Field + +The type field is used to switch the frame message type. The following +message types are supported: + +* 0x0 Data - Used to transmit data. May transmit zero length payloads + depending on the flags. + +* 0x1 Window Update - Used to updated the senders receive window size. + This is used to implement per-session flow control. + +* 0x2 Ping - Used to measure RTT. It can also be used to heart-beat + and do keep-alives over TCP. + +* 0x3 Go Away - Used to close a session. + +## Flag Field + +The flags field is used to provide additional information related +to the message type. The following flags are supported: + +* 0x1 SYN - Signals the start of a new stream. May be sent with a data or + window update message. Also sent with a ping to indicate outbound. + +* 0x2 ACK - Acknowledges the start of a new stream. May be sent with a data + or window update message. Also sent with a ping to indicate response. + +* 0x4 FIN - Performs a half-close of a stream. May be sent with a data + message or window update. + +* 0x8 RST - Reset a stream immediately. May be sent with a data or + window update message. + +## StreamID Field + +The StreamID field is used to identify the logical stream the frame +is addressing. The client side should use odd ID's, and the server even. +This prevents any collisions. Additionally, the 0 ID is reserved to represent +the session. + +Both Ping and Go Away messages should always use the 0 StreamID. + +## Length Field + +The meaning of the length field depends on the message type: + +* Data - provides the length of bytes following the header +* Window update - provides a delta update to the window size +* Ping - Contains an opaque value, echoed back +* Go Away - Contains an error code + +# Message Flow + +There is no explicit connection setup, as Yamux relies on an underlying +transport to be provided. However, there is a distinction between client +and server side of the connection. + +## Opening a stream + +To open a stream, an initial data or window update frame is sent +with a new StreamID. The SYN flag should be set to signal a new stream. + +The receiver must then reply with either a data or window update frame +with the StreamID along with the ACK flag to accept the stream or with +the RST flag to reject the stream. + +Because we are relying on the reliable stream underneath, a connection +can begin sending data once the SYN flag is sent. The corresponding +ACK does not need to be received. This is particularly well suited +for an RPC system where a client wants to open a stream and immediately +fire a request without waiting for the RTT of the ACK. + +This does introduce the possibility of a connection being rejected +after data has been sent already. This is a slight semantic difference +from TCP, where the conection cannot be refused after it is opened. +Clients should be prepared to handle this by checking for an error +that indicates a RST was received. + +## Closing a stream + +To close a stream, either side sends a data or window update frame +along with the FIN flag. This does a half-close indicating the sender +will send no further data. + +Once both sides have closed the connection, the stream is closed. + +Alternatively, if an error occurs, the RST flag can be used to +hard close a stream immediately. + +## Flow Control + +When Yamux is initially starts each stream with a 256KB window size. +There is no window size for the session. + +To prevent the streams from stalling, window update frames should be +sent regularly.
