 # go-winio
 This repository contains utilities for efficiently performing Win32 IO operations in
 Go. Currently, this is focused on accessing named pipes and other file handles, and
 for using named pipes as a net transport.
 This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
 to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
 newer operating systems. This is similar to the implementation of network sockets in Go's net
 package.
 Please see the LICENSE file for licensing information.

 questions or comments.
 Thanks to natefinch for the inspiration for this library. See https://github.com/natefinch/npipe
 for another named pipe implementation.

 # Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>&nbsp;[![Build Status](https://travis-ci.org/Sirupsen/logrus.svg?branch=master)](https://travis-ci.org/Sirupsen/logrus)&nbsp;[![GoDoc](https://godoc.org/github.com/Sirupsen/logrus?status.svg)](https://godoc.org/github.com/Sirupsen/logrus)
 Logrus is a structured logger for Go (golang), completely API compatible with
 the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
 yet stable (pre 1.0). Logrus itself is completely stable and has been used in
 many large deployments. The core API is unlikely to change much but please
 version control your Logrus to make sure you aren't fetching latest `master` on
 every build.**
 Nicely color-coded in development (when a TTY is attached, otherwise just
 plain text):
 ![Colored](http://i.imgur.com/PY7qMwd.png)
 With `log.SetFormatter(&log.JSONFormatter{})`, for easy parsing by logstash
 or Splunk:
 ```json
 {"animal":"walrus","level":"info","msg":"A group of walrus emerges from the
 ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"}
 {"level":"warning","msg":"The group's number increased tremendously!",
 "number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"}
 {"animal":"walrus","level":"info","msg":"A giant walrus appears!",
 "size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"}
 {"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.",
 "size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"}
 {"level":"fatal","msg":"The ice breaks!","number":100,"omg":true,
 "time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
 ```
 With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not
 attached, the output is compatible with the
 [logfmt](http://godoc.org/github.com/kr/logfmt) format:
 ```text
 time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8
 time="2015-03-26T01:27:38-04:00" level=info msg="A group of walrus emerges from the ocean" animal=walrus size=10
 time="2015-03-26T01:27:38-04:00" level=warning msg="The group's number increased tremendously!" number=122 omg=true
 time="2015-03-26T01:27:38-04:00" level=debug msg="Temperature changes" temperature=-4
 time="2015-03-26T01:27:38-04:00" level=panic msg="It's over 9000!" animal=orca size=9009
 time="2015-03-26T01:27:38-04:00" level=fatal msg="The ice breaks!" err=&{0x2082280c0 map[animal:orca size:9009] 2015-03-26 01:27:38.441574009 -0400 EDT panic It's over 9000!} number=100 omg=true
 exit status 1
 ```
 #### Example
 The simplest way to use Logrus is simply the package-level exported logger:
 ```go
 package main
 import (
  log "github.com/Sirupsen/logrus"
 )
 func main() {
  log.WithFields(log.Fields{
    "animal": "walrus",
  }).Info("A walrus appears")
 }
 ```
 Note that it's completely api-compatible with the stdlib logger, so you can
 replace your `log` imports everywhere with `log "github.com/Sirupsen/logrus"`
 and you'll now have the flexibility of Logrus. You can customize it all you
 want:
 ```go
 package main
 import (
  "os"
  log "github.com/Sirupsen/logrus"
 )
 func init() {
  // Log as JSON instead of the default ASCII formatter.
  log.SetFormatter(&log.JSONFormatter{})
  // Output to stderr instead of stdout, could also be a file.
  log.SetOutput(os.Stderr)
  // Only log the warning severity or above.
  log.SetLevel(log.WarnLevel)
 }
 func main() {
  log.WithFields(log.Fields{
    "animal": "walrus",
    "size":   10,
  }).Info("A group of walrus emerges from the ocean")
  log.WithFields(log.Fields{
    "omg":    true,
    "number": 122,
  }).Warn("The group's number increased tremendously!")
  log.WithFields(log.Fields{
    "omg":    true,
    "number": 100,
  }).Fatal("The ice breaks!")
  // A common pattern is to re-use fields between logging statements by re-using
  // the logrus.Entry returned from WithFields()
  contextLogger := log.WithFields(log.Fields{
    "common": "this is a common field",
    "other": "I also should be logged always",
  })
  contextLogger.Info("I'll be logged with common and other field")
  contextLogger.Info("Me too")
 }
 ```
 For more advanced usage such as logging to multiple locations from the same
 application, you can also create an instance of the `logrus` Logger:
 ```go
 package main
 import (
  "github.com/Sirupsen/logrus"
 )
 // Create a new instance of the logger. You can have any number of instances.
 var log = logrus.New()
 func main() {
  // The API for setting attributes is a little different than the package level
  // exported logger. See Godoc.
  log.Out = os.Stderr
  log.WithFields(logrus.Fields{
    "animal": "walrus",
    "size":   10,
  }).Info("A group of walrus emerges from the ocean")
 }
 ```
 #### Fields
 Logrus encourages careful, structured logging though logging fields instead of
 long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
 to send event %s to topic %s with key %d")`, you should log the much more
 discoverable:
 ```go
 log.WithFields(log.Fields{
  "event": event,
  "topic": topic,
  "key": key,
 }).Fatal("Failed to send event")
 ```
 We've found this API forces you to think about logging in a way that produces
 much more useful logging messages. We've been in countless situations where just
 a single added field to a log statement that was already there would've saved us
 hours. The `WithFields` call is optional.
 In general, with Logrus using any of the `printf`-family functions should be
 seen as a hint you should add a field, however, you can still use the
 `printf`-family functions with Logrus.
 #### Hooks
 You can add hooks for logging levels. For example to send errors to an exception
 tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
 multiple places simultaneously, e.g. syslog.
 Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in
 `init`:
 ```go
 import (
  log "github.com/Sirupsen/logrus"
  "gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "aibrake"
  logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
  "log/syslog"
 )
 func init() {
  // Use the Airbrake hook to report errors that have Error severity or above to
  // an exception tracker. You can create custom hooks, see the Hooks section.
  log.AddHook(airbrake.NewHook(123, "xyz", "production"))
  hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
  if err != nil {
    log.Error("Unable to connect to local syslog daemon")
  } else {
    log.AddHook(hook)
  }
 }
 ```
 Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md).

 #### Level logging
 Logrus has six logging levels: Debug, Info, Warning, Error, Fatal and Panic.
 ```go
 log.Debug("Useful debugging information.")
 log.Info("Something noteworthy happened!")
 log.Warn("You should probably take a look at this.")
 log.Error("Something failed but I'm not quitting.")
 // Calls os.Exit(1) after logging
 log.Fatal("Bye.")
 // Calls panic() after logging
 log.Panic("I'm bailing.")
 ```
 You can set the logging level on a `Logger`, then it will only log entries with
 that severity or anything above it:
 ```go
 // Will log anything that is info or above (warn, error, fatal, panic). Default.
 log.SetLevel(log.InfoLevel)
 ```
 It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
 environment if your application has that.
 #### Entries
 Besides the fields added with `WithField` or `WithFields` some fields are
 automatically added to all logging events:
 1. `time`. The timestamp when the entry was created.
 2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
   the `AddFields` call. E.g. `Failed to send event.`
 3. `level`. The logging level. E.g. `info`.
 #### Environments
 Logrus has no notion of environment.
 If you wish for hooks and formatters to only be used in specific environments,
 you should handle that yourself. For example, if your application has a global
 variable `Environment`, which is a string representation of the environment you
 could do:
 ```go
 import (
  log "github.com/Sirupsen/logrus"
 )
 init() {
  // do something here to set environment depending on an environment variable
  // or command-line flag
  if Environment == "production" {
    log.SetFormatter(&log.JSONFormatter{})
  } else {
    // The TextFormatter is default, you don't actually have to do this.
    log.SetFormatter(&log.TextFormatter{})
  }
 }
 ```
 This configuration is how `logrus` was intended to be used, but JSON in
 production is mostly only useful if you do log aggregation with tools like
 Splunk or Logstash.
 #### Formatters
 The built-in logging formatters are:
 * `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
  without colors.
  * *Note:* to force colored output when there is no TTY, set the `ForceColors`
    field to `true`.  To force no colored output even if there is a TTY  set the
    `DisableColors` field to `true`
 * `logrus.JSONFormatter`. Logs fields as JSON.
 Third party logging formatters:
 * [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events.
 * [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout.
 * [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦.
 You can define your formatter by implementing the `Formatter` interface,
 requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
 `Fields` type (`map[string]interface{}`) with all your fields as well as the
 default ones (see Entries section above):
 ```go
 type MyJSONFormatter struct {
 }
 log.SetFormatter(new(MyJSONFormatter))
 func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) {
  // Note this doesn't include Time, Level and Message which are available on
  // the Entry. Consult `godoc` on information about those fields or read the
  // source of the official loggers.
  serialized, err := json.Marshal(entry.Data)
    if err != nil {
      return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err)
    }
  return append(serialized, '\n'), nil
 }
 ```
 #### Logger as an `io.Writer`
 Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
 ```go
 w := logger.Writer()
 defer w.Close()
 srv := http.Server{
    // create a stdlib log.Logger that writes to
    // logrus.Logger.
    ErrorLog: log.New(w, "", 0),
 }
 ```
 Each line written to that writer will be printed the usual way, using formatters
 and hooks. The level for those entries is `info`.
 #### Rotation
 Log rotation is not provided with Logrus. Log rotation should be done by an
 external program (like `logrotate(8)`) that can compress and delete old log
 entries. It should not be a feature of the application-level logger.
 #### Tools
 | Tool | Description |
 | ---- | ----------- |
 |[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will generated with different config at different environment.|
 #### Testing
 Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides:
 * decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just add the `test` hook
 * a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
 ```go
 logger, hook := NewNullLogger()
 logger.Error("Hello error")
 assert.Equal(1, len(hook.Entries))
 assert.Equal(logrus.ErrorLevel, hook.LastEntry().Level)
 assert.Equal("Hello error", hook.LastEntry().Message)
 hook.Reset()
 assert.Nil(hook.LastEntry())
 ```
 #### Fatal handlers
 Logrus can register one or more functions that will be called when any `fatal`
 level message is logged. The registered handlers will be executed before
 logrus performs a `os.Exit(1)`. This behavior may be helpful if callers need
 to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted.
 ```
 ...
 handler := func() {
  // gracefully shutdown something...
 }
 logrus.RegisterExitHandler(handler)
 ...
 ```

 # Building the registry source
 ## Use-case
 This is useful if you intend to actively work on the registry.
 ### Alternatives
 Most people should use the [official Registry docker image](https://hub.docker.com/r/library/registry/).
 People looking for advanced operational use cases might consider rolling their own image with a custom Dockerfile inheriting `FROM registry:2`.
 OS X users who want to run natively can do so following [the instructions here](osx-setup-guide.md).
 ### Gotchas
 You are expected to know your way around with go & git.
 If you are a casual user with no development experience, and no preliminary knowledge of go, building from source is probably not a good solution for you.
 ## Build the development environment
 The first prerequisite of properly building distribution targets is to have a Go
 development environment setup. Please follow [How to Write Go Code](https://golang.org/doc/code.html)
 for proper setup. If done correctly, you should have a GOROOT and GOPATH set in the
 environment.
 If a Go development environment is setup, one can use `go get` to install the
 `registry` command from the current latest:
    go get github.com/docker/distribution/cmd/registry
 The above will install the source repository into the `GOPATH`.
 Now create the directory for the registry data (this might require you to set permissions properly)
    mkdir -p /var/lib/registry
 ... or alternatively `export REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/somewhere` if you want to store data into another location.
 The `registry`
 binary can then be run with the following:
    $ $GOPATH/bin/registry --version
    $GOPATH/bin/registry github.com/docker/distribution v2.0.0-alpha.1+unknown
 > __NOTE:__ While you do not need to use `go get` to checkout the distribution
 > project, for these build instructions to work, the project must be checked
 > out in the correct location in the `GOPATH`. This should almost always be
 > `$GOPATH/src/github.com/docker/distribution`.
 The registry can be run with the default config using the following
 incantation:
    $ $GOPATH/bin/registry serve $GOPATH/src/github.com/docker/distribution/cmd/registry/config-example.yml
    INFO[0000] endpoint local-5003 disabled, skipping        app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
    INFO[0000] endpoint local-8083 disabled, skipping        app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
    INFO[0000] listening on :5000                            app.id=34bbec38-a91a-494a-9a3f-b72f9010081f version=v2.0.0-alpha.1+unknown
    INFO[0000] debug server listening localhost:5001
 If it is working, one should see the above log messages.
 ### Repeatable Builds
 For the full development experience, one should `cd` into
 `$GOPATH/src/github.com/docker/distribution`. From there, the regular `go`
 commands, such as `go test`, should work per package (please see
 [Developing](#developing) if they don't work).
 A `Makefile` has been provided as a convenience to support repeatable builds.
 Please install the following into `GOPATH` for it to work:
    go get github.com/tools/godep github.com/golang/lint/golint
 **TODO(stevvooe):** Add a `make setup` command to Makefile to run this. Have to think about how to interact with Godeps properly.
 Once these commands are available in the `GOPATH`, run `make` to get a full
 build:
    $ make
    + clean
    + fmt
    + vet
    + lint
    + build
    github.com/docker/docker/vendor/src/code.google.com/p/go/src/pkg/archive/tar
    github.com/Sirupsen/logrus
    github.com/docker/libtrust
    ...
    github.com/yvasiyarov/gorelic
    github.com/docker/distribution/registry/handlers
    github.com/docker/distribution/cmd/registry
    + test
    ...
    ok    github.com/docker/distribution/digest 7.875s
    ok    github.com/docker/distribution/manifest 0.028s
    ok    github.com/docker/distribution/notifications  17.322s
    ?     github.com/docker/distribution/registry [no test files]
    ok    github.com/docker/distribution/registry/api/v2  0.101s
    ?     github.com/docker/distribution/registry/auth  [no test files]
    ok    github.com/docker/distribution/registry/auth/silly  0.011s
    ...
    + /Users/sday/go/src/github.com/docker/distribution/bin/registry
    + /Users/sday/go/src/github.com/docker/distribution/bin/registry-api-descriptor-template
    + binaries
 The above provides a repeatable build using the contents of the vendored
 Godeps directory. This includes formatting, vetting, linting, building,
 testing and generating tagged binaries. We can verify this worked by running
 the registry binary generated in the "./bin" directory:
    $ ./bin/registry -version
    ./bin/registry github.com/docker/distribution v2.0.0-alpha.2-80-g16d8b2c.m
 ### Optional build tags
 Optional [build tags](http://golang.org/pkg/go/build/) can be provided using
 the environment variable `DOCKER_BUILDTAGS`.

 # Contributing to the registry
 ## Before reporting an issue...
 ### If your problem is with...
 - automated builds
 - your account on the [Docker Hub](https://hub.docker.com/)
 - any other [Docker Hub](https://hub.docker.com/) issue
 Then please do not report your issue here - you should instead report it to [https://support.docker.com](https://support.docker.com)
 ### If you...
 - need help setting up your registry
 - can't figure out something
 - are not sure what's going on or what your problem is
 Then please do not open an issue here yet - you should first try one of the following support forums:
 - irc: #docker-distribution on freenode
 - mailing-list: <distribution@dockerproject.org> or https://groups.google.com/a/dockerproject.org/forum/#!forum/distribution
 ## Reporting an issue properly
 By following these simple rules you will get better and faster feedback on your issue.
 - search the bugtracker for an already reported issue
 ### If you found an issue that describes your problem:
 - please read other user comments first, and confirm this is the same issue: a given error condition might be indicative of different problems - you may also find a workaround in the comments
 - please refrain from adding "same thing here" or "+1" comments
 - you don't need to comment on an issue to get notified of updates: just hit the "subscribe" button
 - comment if you have some new, technical and relevant information to add to the case
 - __DO NOT__ comment on closed issues or merged PRs. If you think you have a related problem, open up a new issue and reference the PR or issue.
 ### If you have not found an existing issue that describes your problem:
 1. create a new issue, with a succinct title that describes your issue:
   - bad title: "It doesn't work with my docker"
   - good title: "Private registry push fail: 400 error with E_INVALID_DIGEST"
 2. copy the output of:
   - `docker version`
   - `docker info`
   - `docker exec <registry-container> registry -version`
 3. copy the command line you used to launch your Registry
 4. restart your docker daemon in debug mode (add `-D` to the daemon launch arguments)
 5. reproduce your problem and get your docker daemon logs showing the error
 6. if relevant, copy your registry logs that show the error
 7. provide any relevant detail about your specific Registry configuration (e.g., storage backend used)
 8. indicate if you are using an enterprise proxy, Nginx, or anything else between you and your Registry
 ## Contributing a patch for a known bug, or a small correction
 You should follow the basic GitHub workflow:
 1. fork
 2. commit a change
 3. make sure the tests pass
 4. PR
 Additionally, you must [sign your commits](https://github.com/docker/docker/blob/master/CONTRIBUTING.md#sign-your-work). It's very simple:
 - configure your name with git: `git config user.name "Real Name" && git config user.email mail@example.com`
 - sign your commits using `-s`: `git commit -s -m "My commit"`
 Some simple rules to ensure quick merge:
 - clearly point to the issue(s) you want to fix in your PR comment (e.g., `closes #12345`)
 - prefer multiple (smaller) PRs addressing individual issues over a big one trying to address multiple issues at once
 - if you need to amend your PR following comments, please squash instead of adding more commits
 ## Contributing new features
 You are heavily encouraged to first discuss what you want to do. You can do so on the irc channel, or by opening an issue that clearly describes the use case you want to fulfill, or the problem you are trying to solve.
 If this is a major new feature, you should then submit a proposal that describes your technical solution and reasoning.
 If you did discuss it first, this will likely be greenlighted very fast. It's advisable to address all feedback on this proposal before starting actual work.
 Then you should submit your implementation, clearly linking to the issue (and possible proposal).
 Your PR will be reviewed by the community, then ultimately by the project maintainers, before being merged.
 It's mandatory to:
 - interact respectfully with other community members and maintainers - more generally, you are expected to abide by the [Docker community rules](https://github.com/docker/docker/blob/master/CONTRIBUTING.md#docker-community-guidelines)
 - address maintainers' comments and modify your submission accordingly
 - write tests for any new code
 Complying to these simple rules will greatly accelerate the review process, and will ensure you have a pleasant experience in contributing code to the Registry.
 Have a look at a great, successful contribution: the [Swift driver PR](https://github.com/docker/distribution/pull/493)
 ## Coding Style
 Unless explicitly stated, we follow all coding guidelines from the Go
 community. While some of these standards may seem arbitrary, they somehow seem
 to result in a solid, consistent codebase.
 It is possible that the code base does not currently comply with these
 guidelines. We are not looking for a massive PR that fixes this, since that
 goes against the spirit of the guidelines. All new contributions should make a
 best effort to clean up and make the code base better than they left it.
 Obviously, apply your best judgement. Remember, the goal here is to make the
 code base easier for humans to navigate and understand. Always keep that in
 mind when nudging others to comply.
 The rules:
 1. All code should be formatted with `gofmt -s`.
 2. All code should pass the default levels of
   [`golint`](https://github.com/golang/lint).
 3. All code should follow the guidelines covered in [Effective
   Go](http://golang.org/doc/effective_go.html) and [Go Code Review
   Comments](https://github.com/golang/go/wiki/CodeReviewComments).
 4. Comment the code. Tell us the why, the history and the context.
 5. Document _all_ declarations and methods, even private ones. Declare
   expectations, caveats and anything else that may be important. If a type
   gets exported, having the comments already there will ensure it's ready.
 6. Variable name length should be proportional to its context and no longer.
   `noCommaALongVariableNameLikeThisIsNotMoreClearWhenASimpleCommentWouldDo`.
   In practice, short methods will have short variable names and globals will
   have longer names.
 7. No underscores in package names. If you need a compound name, step back,
   and re-examine why you need a compound name. If you still think you need a
   compound name, lose the underscore.
 8. No utils or helpers packages. If a function is not general enough to
   warrant its own package, it has not been written generally enough to be a
   part of a util package. Just leave it unexported and well-documented.
 9. All tests should run with `go test` and outside tooling should not be
   required. No, we don't need another unit testing framework. Assertion
   packages are acceptable if they provide _real_ incremental value.
 10. Even though we call these "rules" above, they are actually just
    guidelines. Since you've read all the rules, you now know that.
 If you are having trouble getting into the mood of idiomatic Go, we recommend
 reading through [Effective Go](http://golang.org/doc/effective_go.html). The
 [Go Blog](http://blog.golang.org/) is also a great resource. Drinking the
 kool-aid is a lot easier than going thirsty.

 ### How does this integrate with Docker engine?
 This project should provide an implementation to a V2 API for use in the [Docker
 core project](https://github.com/docker/docker). The API should be embeddable
 and simplify the process of securely pulling and pushing content from `docker`
 daemons.
 ### What are the long term goals of the Distribution project?
 The _Distribution_ project has the further long term goal of providing a
 secure tool chain for distributing content. The specifications, APIs and tools
 should be as useful with Docker as they are without.
 Our goal is to design a professional grade and extensible content distribution
 system that allow users to:
 * Enjoy an efficient, secured and reliable way to store, manage, package and
  exchange content
 * Hack/roll their own on top of healthy open-source components
 * Implement their own home made solution through good specs, and solid
  extensions mechanism.
 ## More about Registry 2.0
 The new registry implementation provides the following benefits:
 - faster push and pull
 - new, more efficient implementation
 - simplified deployment
 - pluggable storage backend
 - webhook notifications
 For information on upcoming functionality, please see [ROADMAP.md](ROADMAP.md).
 ### Who needs to deploy a registry?
 By default, Docker users pull images from Docker's public registry instance.
 [Installing Docker](https://docs.docker.com/engine/installation/) gives users this
 ability. Users can also push images to a repository on Docker's public registry,
 if they have a [Docker Hub](https://hub.docker.com/) account. 
 For some users and even companies, this default behavior is sufficient. For
 others, it is not. 
 For example, users with their own software products may want to maintain a
 registry for private, company images. Also, you may wish to deploy your own
 image repository for images used to test or in continuous integration. For these
 use cases and others, [deploying your own registry instance](docs/deploying.md)
 may be the better choice.
 ### Migration to Registry 2.0
 For those who have previously deployed their own registry based on the Registry
 1.0 implementation and wish to deploy a Registry 2.0 while retaining images,
 data migration is required. A tool to assist with migration efforts has been
 created. For more information see [docker/migrator]
 (https://github.com/docker/migrator).

 # Roadmap
 The Distribution Project consists of several components, some of which are
 still being defined. This document defines the high-level goals of the
 project, identifies the current components, and defines the release-
 relationship to the Docker Platform.
 * [Distribution Goals](#distribution-goals)
 * [Distribution Components](#distribution-components)
 * [Project Planning](#project-planning): release-relationship to the Docker Platform.
 This road map is a living document, providing an overview of the goals and
 considerations made in respect of the future of the project.
 ## Distribution Goals
 - Replace the existing [docker registry](github.com/docker/docker-registry)
  implementation as the primary implementation.
 - Replace the existing push and pull code in the docker engine with the
  distribution package.
 - Define a strong data model for distributing docker images
 - Provide a flexible distribution tool kit for use in the docker platform
 - Unlock new distribution models
 ## Distribution Components
 Components of the Distribution Project are managed via github [milestones](https://github.com/docker/distribution/milestones). Upcoming
 features and bugfixes for a component will be added to the relevant milestone. If a feature or
 bugfix is not part of a milestone, it is currently unscheduled for
 implementation. 
 * [Registry](#registry)
 * [Distribution Package](#distribution-package)
 ***
 ### Registry
 The new Docker registry is the main portion of the distribution repository.
 Registry 2.0 is the first release of the next-generation registry. This was
 primarily focused on implementing the [new registry
 API](https://github.com/docker/distribution/blob/master/docs/spec/api.md),
 with a focus on security and performance. 
 Following from the Distribution project goals above, we have a set of goals
 for registry v2 that we would like to follow in the design. New features
 should be compared against these goals.
 #### Data Storage and Distribution First
 The registry's first goal is to provide a reliable, consistent storage
 location for Docker images. The registry should only provide the minimal
 amount of indexing required to fetch image data and no more.
 This means we should be selective in new features and API additions, including
 those that may require expensive, ever growing indexes. Requests should be
 servable in "constant time".
 #### Content Addressability
 All data objects used in the registry API should be content addressable.
 Content identifiers should be secure and verifiable. This provides a secure,
 reliable base from which to build more advanced content distribution systems.
 #### Content Agnostic
 In the past, changes to the image format would require large changes in Docker
 and the Registry. By decoupling the distribution and image format, we can
 allow the formats to progress without having to coordinate between the two.
 This means that we should be focused on decoupling Docker from the registry
 just as much as decoupling the registry from Docker. Such an approach will
 allow us to unlock new distribution models that haven't been possible before.
 We can take this further by saying that the new registry should be content
 agnostic. The registry provides a model of names, tags, manifests and content
 addresses and that model can be used to work with content.
 #### Simplicity
 The new registry should be closer to a microservice component than its
 predecessor. This means it should have a narrower API and a low number of
 service dependencies. It should be easy to deploy.
 This means that other solutions should be explored before changing the API or
 adding extra dependencies. If functionality is required, can it be added as an
 extension or companion service.
 #### Extensibility
 The registry should provide extension points to add functionality. By keeping
 the scope narrow, but providing the ability to add functionality.
 Features like search, indexing, synchronization and registry explorers fall
 into this category. No such feature should be added unless we've found it
 impossible to do through an extension.
 #### Active Feature Discussions
 The following are feature discussions that are currently active.
 If you don't see your favorite, unimplemented feature, feel free to contact us
 via IRC or the mailing list and we can talk about adding it. The goal here is
 to make sure that new features go through a rigid design process before
 landing in the registry.
 ##### Proxying to other Registries
 A _pull-through caching_ mode exists for the registry, but is restricted from 
 within the docker client to only mirror the official Docker Hub.  This functionality
 can be expanded when image provenance has been specified and implemented in the 
 distribution project.
 ##### Metadata storage
 Metadata for the registry is currently stored with the manifest and layer data on
 the storage backend.  While this is a big win for simplicity and reliably maintaining
 state, it comes with the cost of consistency and high latency.  The mutable registry
 metadata operations should be abstracted behind an API which will allow ACID compliant
 storage systems to handle metadata.
 ##### Peer to Peer transfer
 Discussion has started here: https://docs.google.com/document/d/1rYDpSpJiQWmCQy8Cuiaa3NH-Co33oK_SC9HeXYo87QA/edit
 ##### Indexing, Search and Discovery
 The original registry provided some implementation of search for use with
 private registries. Support has been elided from V2 since we'd like to both
 decouple search functionality from the registry. The makes the registry
 simpler to deploy, especially in use cases where search is not needed, and
 let's us decouple the image format from the registry.
 There are explorations into using the catalog API and notification system to
 build external indexes. The current line of thought is that we will define a
 common search API to index and query docker images. Such a system could be run
 as a companion to a registry or set of registries to power discovery.
 The main issue with search and discovery is that there are so many ways to
 accomplish it. There are two aspects to this project. The first is deciding on
 how it will be done, including an API definition that can work with changing
 data formats. The second is the process of integrating with `docker search`.
 We expect that someone attempts to address the problem with the existing tools
 and propose it as a standard search API or uses it to inform a standardization
 process. Once this has been explored, we integrate with the docker client.
 Please see the following for more detail:
 - https://github.com/docker/distribution/issues/206
 ##### Deletes
 > __NOTE:__ Deletes are a much asked for feature. Before requesting this
 feature or participating in discussion, we ask that you read this section in
 full and understand the problems behind deletes.
 While, at first glance, implementing deleting seems simple, there are a number
 mitigating factors that make many solutions not ideal or even pathological in
 the context of a registry. The following paragraph discuss the background and
 approaches that could be applied to arrive at a solution.
 The goal of deletes in any system is to remove unused or unneeded data. Only
 data requested for deletion should be removed and no other data. Removing
 unintended data is worse than _not_ removing data that was requested for
 removal but ideally, both are supported. Generally, according to this rule, we
 err on holding data longer than needed, ensuring that it is only removed when
 we can be certain that it can be removed. With the current behavior, we opt to
 hold onto the data forever, ensuring that data cannot be incorrectly removed.
 To understand the problems with implementing deletes, one must understand the
 data model. All registry data is stored in a filesystem layout, implemented on
 a "storage driver", effectively a _virtual file system_ (VFS). The storage
 system must assume that this VFS layer will be eventually consistent and has
 poor read- after-write consistency, since this is the lower common denominator
 among the storage drivers. This is mitigated by writing values in reverse-
 dependent order, but makes wider transactional operations unsafe.
 Layered on the VFS model is a content-addressable _directed, acyclic graph_
 (DAG) made up of blobs. Manifests reference layers. Tags reference manifests.
 Since the same data can be referenced by multiple manifests, we only store
 data once, even if it is in different repositories. Thus, we have a set of
 blobs, referenced by tags and manifests. If we want to delete a blob we need
 to be certain that it is no longer referenced by another manifest or tag. When
 we delete a manifest, we also can try to delete the referenced blobs. Deciding
 whether or not a blob has an active reference is the crux of the problem.
 Conceptually, deleting a manifest and its resources is quite simple. Just find
 all the manifests, enumerate the referenced blobs and delete the blobs not in
 that set. An astute observer will recognize this as a garbage collection
 problem. As with garbage collection in programming languages, this is very
 simple when one always has a consistent view. When one adds parallelism and an
 inconsistent view of data, it becomes very challenging.
 A simple example can demonstrate this. Let's say we are deleting a manifest
 _A_ in one process. We scan the manifest and decide that all the blobs are
 ready for deletion. Concurrently, we have another process accepting a new
 manifest _B_ referencing one or more blobs from the manifest _A_. Manifest _B_
 is accepted and all the blobs are considered present, so the operation
 proceeds. The original process then deletes the referenced blobs, assuming
 they were unreferenced. The manifest _B_, which we thought had all of its data
 present, can no longer be served by the registry, since the dependent data has
 been deleted.
 Deleting data from the registry safely requires some way to coordinate this
 operation. The following approaches are being considered:
 - _Reference Counting_ - Maintain a count of references to each blob. This is
  challenging for a number of reasons: 1. maintaining a consistent consensus
  of reference counts across a set of Registries and 2. Building the initial
  list of reference counts for an existing registry. These challenges can be
  met with a consensus protocol like Paxos or Raft in the first case and a
  necessary but simple scan in the second..
 - _Lock the World GC_ - Halt all writes to the data store. Walk the data store
  and find all blob references. Delete all unreferenced blobs. This approach
  is very simple but requires disabling writes for a period of time while the
  service reads all data. This is slow and expensive but very accurate and
  effective.
 - _Generational GC_ - Do something similar to above but instead of blocking
  writes, writes are sent to another storage backend while reads are broadcast
  to the new and old backends. GC is then performed on the read-only portion.
  Because writes land in the new backend, the data in the read-only section
  can be safely deleted. The main drawbacks of this approach are complexity
  and coordination.
 - _Centralized Oracle_ - Using a centralized, transactional database, we can
  know exactly which data is referenced at any given time. This avoids
  coordination problem by managing this data in a single location. We trade
  off metadata scalability for simplicity and performance. This is a very good
  option for most registry deployments. This would create a bottleneck for
  registry metadata. However, metadata is generally not the main bottleneck
  when serving images.
 Please let us know if other solutions exist that we have yet to enumerate.
 Note that for any approach, implementation is a massive consideration. For
 example, a mark-sweep based solution may seem simple but the amount of work in
 coordination offset the extra work it might take to build a _Centralized
 Oracle_. We'll accept proposals for any solution but please coordinate with us
 before dropping code.
 At this time, we have traded off simplicity and ease of deployment for disk
 space. Simplicity and ease of deployment tend to reduce developer involvement,
 which is currently the most expensive resource in software engineering. Taking
 on any solution for deletes will greatly effect these factors, trading off
 very cheap disk space for a complex deployment and operational story.

 ### Distribution Package 
 At its core, the Distribution Project is a set of Go packages that make up
 Distribution Components. At this time, most of these packages make up the
 Registry implementation. 
 The package itself is considered unstable. If you're using it, please take care to vendor the dependent version. 
 For feature additions, please see the Registry section. In the future, we may break out a
 separate Roadmap for distribution-specific features that apply to more than
 just the registry.
 ***
 ### Project Planning
 An [Open-Source Planning Process](https://github.com/docker/distribution/wiki/Open-Source-Planning-Process) is used to define the Roadmap. [Project Pages](https://github.com/docker/distribution/wiki) define the goals for each Milestone and identify current progress.

 // Package context provides several utilities for working with
 // golang.org/x/net/context in http requests. Primarily, the focus is on
 // logging relevant request information but this package is not limited to
 // that purpose.
 //
 // The easiest way to get started is to get the background context:
 //
 // 	ctx := context.Background()
 //
 // The returned context should be passed around your application and be the
 // root of all other context instances. If the application has a version, this
 // line should be called before anything else:
 //
 // 	ctx := context.WithVersion(context.Background(), version)
 //
 // The above will store the version in the context and will be available to
 // the logger.
 //
 // Logging
 //
 // The most useful aspect of this package is GetLogger. This function takes
 // any context.Context interface and returns the current logger from the
 // context. Canonical usage looks like this:
 //
 // 	GetLogger(ctx).Infof("something interesting happened")
 //
 // GetLogger also takes optional key arguments. The keys will be looked up in
 // the context and reported with the logger. The following example would
 // return a logger that prints the version with each log message:
 //
 // 	ctx := context.Context(context.Background(), "version", version)
 // 	GetLogger(ctx, "version").Infof("this log message has a version field")
 //
 // The above would print out a log message like this:
 //
 // 	INFO[0000] this log message has a version field        version=v2.0.0-alpha.2.m
 //
 // When used with WithLogger, we gain the ability to decorate the context with
 // loggers that have information from disparate parts of the call stack.
 // Following from the version example, we can build a new context with the
 // configured logger such that we always print the version field:
 //
 // 	ctx = WithLogger(ctx, GetLogger(ctx, "version"))
 //
 // Since the logger has been pushed to the context, we can now get the version
 // field for free with our log messages. Future calls to GetLogger on the new
 // context will have the version field:
 //
 // 	GetLogger(ctx).Infof("this log message has a version field")
 //
 // This becomes more powerful when we start stacking loggers. Let's say we
 // have the version logger from above but also want a request id. Using the
 // context above, in our request scoped function, we place another logger in
 // the context:
 //
 // 	ctx = context.WithValue(ctx, "http.request.id", "unique id") // called when building request context
 // 	ctx = WithLogger(ctx, GetLogger(ctx, "http.request.id"))
 //
 // When GetLogger is called on the new context, "http.request.id" will be
 // included as a logger field, along with the original "version" field:
 //
 // 	INFO[0000] this log message has a version field        http.request.id=unique id version=v2.0.0-alpha.2.m
 //
 // Note that this only affects the new context, the previous context, with the
 // version field, can be used independently. Put another way, the new logger,
 // added to the request context, is unique to that context and can have
 // request scoped varaibles.
 //
 // HTTP Requests
 //
 // This package also contains several methods for working with http requests.
 // The concepts are very similar to those described above. We simply place the
 // request in the context using WithRequest. This makes the request variables
 // available. GetRequestLogger can then be called to get request specific
 // variables in a log line:
 //
 // 	ctx = WithRequest(ctx, req)
 // 	GetRequestLogger(ctx).Infof("request variables")
 //
 // Like above, if we want to include the request data in all log messages in
 // the context, we push the logger to a new context and use that one:
 //
 // 	ctx = WithLogger(ctx, GetRequestLogger(ctx))
 //
 // The concept is fairly powerful and ensures that calls throughout the stack
 // can be traced in log messages. Using the fields like "http.request.id", one
 // can analyze call flow for a particular request with a simple grep of the
 // logs.
