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). + +| Hook | Description | +| ----- | ----------- | +| [Airbrake](https://github.com/gemnasium/logrus-airbrake-hook) | Send errors to the Airbrake API V3.

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.| +|[Logrus Viper Helper](https://github.com/heirko/go-contrib/tree/master/logrusHelper)|An Helper arround Logrus to wrap with spf13/Viper to load configuration with fangs! And to simplify Logrus configuration use some behavior of [Logrus Mate](https://github.com/gogap/logrus_mate). [sample](https://github.com/heirko/iris-contrib/blob/master/middleware/logrus-logger/example) | + +#### 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) +... +``` + +#### Thread safty + +By default Logger is protected by mutex for concurrent writes, this mutex is invoked when calling hooks and writing logs. +If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking. + +Situation when locking is not needed includes: + +* You have no hooks registered, or hooks calling is already thread-safe. + +* Writing to logger.Out is already thread-safe, for example: + + 1) logger.Out is protected by locks. + + 2) logger.Out is a os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allow multi-thread/multi-process writing) + + (Refer to http://www.notthewizard.com/2014/06/17/are-files-appends-really-atomic/) diff --git a/vendor/github.com/aws/aws-sdk-go/LICENSE.txt b/vendor/github.com/aws/aws-sdk-go/LICENSE.txt new file mode 100644 index 00000000..d6456956 --- /dev/null +++ b/vendor/github.com/aws/aws-sdk-go/LICENSE.txt @@ -0,0 +1,202 @@ + + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

[Create a free account](http://bugsnag.com) to start +capturing exceptions from your applications. + +## How to Install + +1. Download the code + + ```shell + go get github.com/bugsnag/bugsnag-go + ``` + +### Using with net/http apps + +For a golang app based on [net/http](https://godoc.org/net/http), integrating +Bugsnag takes two steps. You should also use these instructions if you're using +the [gorilla toolkit](http://www.gorillatoolkit.org/), or the +[pat](https://github.com/bmizerany/pat/) muxer. + +1. Configure bugsnag at the start of your `main()` function: + + ```go + import "github.com/bugsnag/bugsnag-go" + + func main() { + bugsnag.Configure(bugsnag.Configuration{ + APIKey: "YOUR_API_KEY_HERE", + ReleaseStage: "production", + // more configuration options + }) + + // rest of your program. + } + ``` + +2.

Add the `bugsnagrevel.Filter` immediately after the `revel.PanicFilter` in `app/init.go`: + + ```go + + import "github.com/bugsnag/bugsnag-go/revel" + + revel.Filters = []revel.Filter{ + revel.PanicFilter, + bugsnagrevel.Filter, + // ... + } + ``` + +2. Set bugsnag.apikey in the top section of `conf/app.conf`. + + ``` + module.static=github.com/revel/revel/modules/static + + bugsnag.apikey=YOUR_API_KEY_HERE + + [dev] + ``` + +### Using with Google App Engine + +1. Configure bugsnag at the start of your `init()` function: + + ```go + import "github.com/bugsnag/bugsnag-go" + + func init() { + bugsnag.Configure(bugsnag.Configuration{ + APIKey: "YOUR_API_KEY_HERE", + }) + + // ... + } + ``` + +2. Wrap *every* http.Handler or http.HandlerFunc with Bugsnag: + + ```go + // a. If you're using HandlerFuncs + http.HandleFunc("/", bugsnag.HandlerFunc( + func (w http.ResponseWriter, r *http.Request) { + // ... + })) + + // b. If you're using Handlers + http.Handle("/", bugsnag.Handler(myHttpHandler)) + ``` + +3. In order to use Bugsnag, you must provide the current +[`appengine.Context`](https://developers.google.com/appengine/docs/go/reference#Context), or +current `*http.Request` as rawData. The easiest way to do this is to create a new notifier. + + ```go + c := appengine.NewContext(r) + notifier := bugsnag.New(c) + + if err != nil { + notifier.Notify(err) + } + + go func () { + defer notifier.Recover() + + // ... + }() + ``` + + +## Notifying Bugsnag manually + +Bugsnag will automatically handle any panics that crash your program and notify +you of them. If you've integrated with `revel` or `net/http`, then you'll also +be notified of any panics() that happen while processing a request. + +Sometimes however it's useful to manually notify Bugsnag of a problem. To do this, +call [`bugsnag.Notify()`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Notify) + +```go +if err != nil { + bugsnag.Notify(err) +} +``` + +### Manual panic handling + +To avoid a panic in a goroutine from crashing your entire app, you can use +[`bugsnag.Recover()`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Recover) +to stop a panic from unwinding the stack any further. When `Recover()` is hit, +it will send any current panic to Bugsnag and then stop panicking. This is +most useful at the start of a goroutine: + +```go +go func() { + defer bugsnag.Recover() + + // ... +}() +``` + +Alternatively you can use +[`bugsnag.AutoNotify()`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Recover) +to notify bugsnag of a panic while letting the program continue to panic. This +is useful if you're using a Framework that already has some handling of panics +and you are retrofitting bugsnag support. + +```go +defer bugsnag.AutoNotify() +``` + +## Sending Custom Data + +Most functions in the Bugsnag API, including `bugsnag.Notify()`, +`bugsnag.Recover()`, `bugsnag.AutoNotify()`, and `bugsnag.Handler()` let you +attach data to the notifications that they send. To do this you pass in rawData, +which can be any of the supported types listed here. To add support for more +types of rawData see [OnBeforeNotify](#custom-data-with-onbeforenotify). + +### Custom MetaData + +Custom metaData appears as tabs on Bugsnag.com. You can set it by passing +a [`bugsnag.MetaData`](https://godoc.org/github.com/bugsnag/bugsnag-go/#MetaData) +object as rawData. + +```go +bugsnag.Notify(err, + bugsnag.MetaData{ + "Account": { + "Name": Account.Name, + "Paying": Account.Plan.Premium, + }, + }) +``` + +### Request data + +Bugsnag can extract interesting data from +[`*http.Request`](https://godoc.org/net/http/#Request) objects, and +[`*revel.Controller`](https://godoc.org/github.com/revel/revel/#Controller) +objects. These are automatically passed in when handling panics, and you can +pass them yourself. + +```go +func (w http.ResponseWriter, r *http.Request) { + bugsnag.Notify(err, r) +} +``` + +### User data + +User data is searchable, and the `Id` powers the count of users affected. You +can set which user an error affects by passing a +[`bugsnag.User`](https://godoc.org/github.com/bugsnag/bugsnag-go/#User) object as +rawData. + +```go +bugsnag.Notify(err, + bugsnag.User{Id: "1234", Name: "Conrad", Email: "me@cirw.in"}) +``` + +### Context + +The context shows up prominently in the list view so that you can get an idea +of where a problem occurred. You can set it by passing a +[`bugsnag.Context`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Context) +object as rawData. + +```go +bugsnag.Notify(err, bugsnag.Context{"backgroundJob"}) +``` + +### Severity + +Bugsnag supports three severities, `SeverityError`, `SeverityWarning`, and `SeverityInfo`. +You can set the severity of an error by passing one of these objects as rawData. + +```go +bugsnag.Notify(err, bugsnag.SeverityInfo) +``` + +## Configuration + +You must call `bugsnag.Configure()` at the start of your program to use Bugsnag, you pass it +a [`bugsnag.Configuration`](https://godoc.org/github.com/bugsnag/bugsnag-go/#Configuration) object +containing any of the following values. + +### APIKey + +The Bugsnag API key can be found on your [Bugsnag dashboard](https://bugsnag.com) under "Settings". + +```go +bugsnag.Configure(bugsnag.Configuration{ + APIKey: "YOUR_API_KEY_HERE", +}) +``` + +### Endpoint + +The Bugsnag endpoint defaults to `https://notify.bugsnag.com/`. If you're using Bugsnag enterprise, +you should set this to the endpoint of your local instance. + +```go +bugsnag.Configure(bugsnag.Configuration{ + Endpoint: "http://bugsnag.internal:49000/", +}) +``` + +### ReleaseStage + +The ReleaseStage tracks where your app is deployed. You should set this to `production`, `staging`, +`development` or similar as appropriate. + +```go +bugsnag.Configure(bugsnag.Configuration{ + ReleaseStage: "development", +}) +``` + +### NotifyReleaseStages + +The list of ReleaseStages to notify in. By default Bugsnag will notify you in all release stages, but +you can use this to silence development errors. + +```go +bugsnag.Configure(bugsnag.Configuration{ + NotifyReleaseStages: []string{"production", "staging"}, +}) +``` + +### AppVersion + +If you use a versioning scheme for deploys of your app, Bugsnag can use the `AppVersion` to only +re-open errors if they occur in later version of the app. + +```go +bugsnag.Configure(bugsnag.Configuration{ + AppVersion: "1.2.3", +}) +``` + +### Hostname + +The hostname is used to track where exceptions are coming from in the Bugsnag dashboard. The +default value is obtained from `os.Hostname()` so you won't often need to change this. + +```go +bugsnag.Configure(bugsnag.Configuration{ + Hostname: "go1", +}) +``` + +### ProjectPackages + +In order to determine where a crash happens Bugsnag needs to know which packages you consider to +be part of your app (as opposed to a library). By default this is set to `[]string{"main*"}`. Strings +are matched to package names using [`filepath.Match`](http://godoc.org/path/filepath#Match). + +```go +bugsnag.Configure(bugsnag.Configuration{ + ProjectPackages: []string{"main", "github.com/domain/myapp/*"}, +} +``` + +### ParamsFilters + +Sometimes sensitive data is accidentally included in Bugsnag MetaData. You can remove it by +setting `ParamsFilters`. Any key in the `MetaData` that includes any string in the filters +will be redacted. The default is `[]string{"password", "secret"}`, which prevents fields like +`password`, `password_confirmation` and `secret_answer` from being sent. + +```go +bugsnag.Configure(bugsnag.Configuration{ + ParamsFilters: []string{"password", "secret"}, +} +``` + +### Logger + +The Logger to write to in case of an error inside Bugsnag. This defaults to the global logger. + +```go +bugsnag.Configure(bugsnag.Configuration{ + Logger: app.Logger, +} +``` + +### PanicHandler + +The first time Bugsnag is configured, it wraps the running program in a panic +handler using [panicwrap](http://godoc.org/github.com/ConradIrwin/panicwrap). This +forks a sub-process which monitors unhandled panics. To prevent this, set +`PanicHandler` to `func() {}` the first time you call +`bugsnag.Configure`. This will prevent bugsnag from being able to notify you about +unhandled panics. + +```go +bugsnag.Configure(bugsnag.Configuration{ + PanicHandler: func() {}, +}) +``` + +### Synchronous + +Bugsnag usually starts a new goroutine before sending notifications. This means +that notifications can be lost if you do a bugsnag.Notify and then immediately +os.Exit. To avoid this problem, set Bugsnag to Synchronous (or just `panic()` +instead ;). + +```go +bugsnag.Configure(bugsnag.Configuration{ + Synchronous: true +}) +``` + +Or just for one error: + +```go +bugsnag.Notify(err, bugsnag.Configuration{Synchronous: true}) +``` + +### Transport + +The transport configures how Bugsnag makes http requests. By default we use +[`http.DefaultTransport`](http://godoc.org/net/http#RoundTripper) which handles +HTTP proxies automatically using the `$HTTP_PROXY` environment variable. + +```go +bugsnag.Configure(bugsnag.Configuration{ + Transport: http.DefaultTransport, +}) +``` + +## Custom data with OnBeforeNotify + +While it's nice that you can pass `MetaData` directly into `bugsnag.Notify`, +`bugsnag.AutoNotify`, and `bugsnag.Recover`, this can be a bit cumbersome and +inefficient — you're constructing the meta-data whether or not it will actually +be used. A better idea is to pass raw data in to these functions, and add an +`OnBeforeNotify` filter that converts them into `MetaData`. + +For example, lets say our system processes jobs: + +```go +type Job struct{ + Retry bool + UserId string + UserEmail string + Name string + Params map[string]string +} +``` + +You can pass a job directly into Bugsnag.notify: + +```go +bugsnag.Notify(err, job) +``` + +And then add a filter to extract information from that job and attach it to the +Bugsnag event: + +```go +bugsnag.OnBeforeNotify( + func(event *bugsnag.Event, config *bugsnag.Configuration) error { + + // Search all the RawData for any *Job pointers that we're passed in + // to bugsnag.Notify() and friends. + for _, datum := range event.RawData { + if job, ok := datum.(*Job); ok { + // don't notify bugsnag about errors in retries + if job.Retry { + return fmt.Errorf("not notifying about retried jobs") + } + + // add the job as a tab on Bugsnag.com + event.MetaData.AddStruct("Job", job) + + // set the user correctly + event.User = &User{Id: job.UserId, Email: job.UserEmail} + } + } + + // continue notifying as normal + return nil + }) +``` + +## Advanced Usage + +If you want to have multiple different configurations around in one program, +you can use `bugsnag.New()` to create multiple independent instances of +Bugsnag. You can use these without calling `bugsnag.Configure()`, but bear in +mind that until you call `bugsnag.Configure()` unhandled panics will not be +sent to bugsnag. + +```go +notifier := bugsnag.New(bugsnag.Configuration{ + APIKey: "YOUR_OTHER_API_KEY", +}) +``` + +In fact any place that lets you pass in `rawData` also allows you to pass in +configuration. For example to send http errors to one bugsnag project, you +could do: + +```go +bugsnag.Handler(nil, bugsnag.Configuration{APIKey: "YOUR_OTHER_API_KEY"}) +``` + +### GroupingHash + +If you need to override Bugsnag's grouping algorithm, you can set the +`GroupingHash` in an `OnBeforeNotify`: + +```go +bugsnag.OnBeforeNotify( + func (event *bugsnag.Event, config *bugsnag.Configuration) error { + event.GroupingHash = calculateGroupingHash(event) + return nil + }) +``` diff --git a/vendor/github.com/bugsnag/bugsnag-go/errors/README.md b/vendor/github.com/bugsnag/bugsnag-go/errors/README.md new file mode 100644 index 00000000..8d8e097a --- /dev/null +++ b/vendor/github.com/bugsnag/bugsnag-go/errors/README.md @@ -0,0 +1,6 @@ +Adds stacktraces to errors in golang. + +This was made to help build the Bugsnag notifier but can be used standalone if +you like to have stacktraces on errors. + +See [Godoc](https://godoc.org/github.com/bugsnag/bugsnag-go/errors) for the API docs. diff --git a/vendor/github.com/bugsnag/panicwrap/README.md b/vendor/github.com/bugsnag/panicwrap/README.md new file mode 100644 index 00000000..d0a59675 --- /dev/null +++ b/vendor/github.com/bugsnag/panicwrap/README.md @@ -0,0 +1,101 @@ +# panicwrap + +panicwrap is a Go library that re-executes a Go binary and monitors stderr +output from the binary for a panic. When it find a panic, it executes a +user-defined handler function. Stdout, stderr, stdin, signals, and exit +codes continue to work as normal, making the existence of panicwrap mostly +invisble to the end user until a panic actually occurs. + +Since a panic is truly a bug in the program meant to crash the runtime, +globally catching panics within Go applications is not supposed to be possible. +Despite this, it is often useful to have a way to know when panics occur. +panicwrap allows you to do something with these panics, such as writing them +to a file, so that you can track when panics occur. + +panicwrap is ***not a panic recovery system***. Panics indicate serious +problems with your application and _should_ crash the runtime. panicwrap +is just meant as a way to monitor for panics. If you still think this is +the worst idea ever, read the section below on why. + +## Features + +* **SIMPLE!** +* Works with all Go applications on all platforms Go supports +* Custom behavior when a panic occurs +* Stdout, stderr, stdin, exit codes, and signals continue to work as + expected. + +## Usage + +Using panicwrap is simple. It behaves a lot like `fork`, if you know +how that works. A basic example is shown below. + +Because it would be sad to panic while capturing a panic, it is recommended +that the handler functions for panicwrap remain relatively simple and well +tested. panicwrap itself contains many tests. + +```go +package main + +import ( + "fmt" + "github.com/mitchellh/panicwrap" + "os" +) + +func main() { + exitStatus, err := panicwrap.BasicWrap(panicHandler) + if err != nil { + // Something went wrong setting up the panic wrapper.

Put it in a file or something. + fmt.Printf("The child panicked:\n\n%s\n", output) + os.Exit(1) +} +``` + +## How Does it Work? + +panicwrap works by re-executing the running program (retaining arguments, +environmental variables, etc.) and monitoring the stderr of the program. +Since Go always outputs panics in a predictable way with a predictable +exit code, panicwrap is able to reliably detect panics and allow the parent +process to handle them. + +## WHY?! Panics should CRASH! + +Yes, panics _should_ crash. They are 100% always indicative of bugs. +However, in some cases, such as user-facing programs (programs like +[Packer](http://github.com/mitchellh/packer) or +[Docker](http://github.com/dotcloud/docker)), it is up to the user to +report such panics. This is unreliable, at best, and it would be better if the +program could have a way to automatically report panics. panicwrap provides +a way to do this. + +For backend applications, it is easier to detect crashes (since the application +exits). However, it is still nice sometimes to more intelligently log +panics in some way. For example, at [HashiCorp](http://www.hashicorp.com), +we use panicwrap to log panics to timestamped files with some additional +data (configuration settings at the time, environmental variables, etc.) + +The goal of panicwrap is _not_ to hide panics. It is instead to provide +a clean mechanism for handling them before bubbling the up to the user +and ultimately crashing. diff --git a/vendor/github.com/denverdino/aliyungo/LICENSE.txt b/vendor/github.com/denverdino/aliyungo/LICENSE.txt new file mode 100644 index 00000000..91829713 --- /dev/null +++ b/vendor/github.com/denverdino/aliyungo/LICENSE.txt @@ -0,0 +1,191 @@ + + Apache License + Version 2.0, January 2004 + https://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

+另一个比较高级的做法是写入到任何实现 `io.Writer` 接口的对象中： + +```go +// ... +cfg.WriteTo(writer) +cfg.WriteToIndent(writer, "\t") +``` + +默认情况下，空格将被用于对齐键值之间的等号以美化输出结果，以下代码可以禁用该功能： + +```go +ini.PrettyFormat = false +``` + +### 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 = https://github.com/%(NAME)s + +[package] +FULL_NAME = github.com/go-ini/%(NAME)s +``` + +```go +cfg.Section("author").Key("GITHUB").String() // https://github.com/Unknwon +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 = v1 +IMPORT_PATH = gopkg.in/%(NAME)s.%(VERSION)s + +[package] +CLONE_URL = https://%(IMPORT_PATH)s + +[package.sub] +``` + +```go +cfg.Section("package.sub").Key("CLONE_URL").String() // https://gopkg.in/ini.v1 +``` + +#### 获取上级父分区下的所有键名 + +```go +cfg.Section("package.sub").ParentKeys() // ["CLONE_URL"] +``` + +#### 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 + +[Note] +Content = Hi is a good man! +Cities = HangZhou, Boston +``` + +```go +type Note struct { + Content string + Cities []string +} + +type Person struct { + Name string + Age int `ini:"age"` + Male bool + Born time.Time + Note + Created time.Time `ini:"-"` +} + +func main() { + cfg, err := ini.Load("path/to/ini") + // ... + p := new(Person) + err = cfg.MapTo(p) + // ... + + // 一切竟可以如此的简单。 + 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:"|"` +

err = ini.ReflectFrom(cfg, a) + // ... +} +``` + +瞧瞧，奇迹发生了。 + +```ini +NAME = Unknwon +Male = true +Age = 21 +GPA = 2.8 + +[Embeded] +Dates = 2015-08-07T22:14:22+08:00|2015-08-07T22:14:22+08:00 +places = HangZhou,Boston +``` + +#### 名称映射器（Name Mapper） + +为了节省您的时间并简化代码，本库支持类型为 [`NameMapper`](https://gowalker.org/gopkg.in/ini.v1#NameMapper) 的名称映射器，该映射器负责结构字段名与分区名和键名之间的映射。 + +目前有 2 款内置的映射器： + +- `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) + +##

It must be in your $PATH for the protocol + compiler, protoc, to find it. + +This software has two parts: a 'protocol compiler plugin' that +generates Go source files that, once compiled, can access and manage +protocol buffers; and a library that implements run-time support for +encoding (marshaling), decoding (unmarshaling), and accessing protocol +buffers. + +There is support for gRPC in Go using protocol buffers. +See the note at the bottom of this file for details. + +There are no insertion points in the plugin. + + +## Using protocol buffers with Go ## + +Once the software is installed, there are two steps to using it. +First you must compile the protocol buffer definitions and then import +them, with the support library, into your program. + +To compile the protocol buffer definition, run protoc with the --go_out +parameter set to the directory you want to output the Go code to. + + protoc --go_out=. *.proto + +The generated files will be suffixed .pb.go. See the Test code below +for an example using such a file. + + +The package comment for the proto library contains text describing +the interface provided in Go for protocol buffers. Here is an edited +version. + +========== + +The proto package converts data structures to and from the +wire format of protocol buffers. It works in concert with the +Go source code generated for .proto files by the protocol compiler. + +A summary of the properties of the protocol buffer interface +for a protocol buffer variable v: + + - Names are turned from camel_case to CamelCase for export. + - There are no methods on v to set fields; just treat + them as structure fields. + - There are getters that return a field's value if set, + and return the field's default value if unset. + The getters work even if the receiver is a nil message. + - The zero value for a struct is its correct initialization state. + All desired fields must be set before marshaling. + - A Reset() method will restore a protobuf struct to its zero state. + - Non-repeated fields are pointers to the values; nil means unset. + That is, optional or required field int32 f becomes F *int32. + - Repeated fields are slices. + - Helper functions are available to aid the setting of fields. + Helpers for getting values are superseded by the + GetFoo methods and their use is deprecated. + msg.Foo = proto.String("hello") // set field + - Constants are defined to hold the default values of all fields that + have them. They have the form Default_StructName_FieldName. + Because the getter methods handle defaulted values, + direct use of these constants should be rare. + - Enums are given type names and maps from names to values. + Enum values are prefixed with the enum's type name. Enum types have + a String method, and a Enum method to assist in message construction. + - Nested groups and enums have type names prefixed with the name of + the surrounding message type. + - Extensions are given descriptor names that start with E_, + followed by an underscore-delimited list of the nested messages + that contain it (if any) followed by the CamelCased name of the + extension field itself. HasExtension, ClearExtension, GetExtension + and SetExtension are functions for manipulating extensions. + - Oneof field sets are given a single field in their message, + with distinguished wrapper types for each possible field value. + - Marshal and Unmarshal are functions to encode and decode the wire format. + +When the .proto file specifies `syntax="proto3"`, there are some differences: + + - Non-repeated fields of non-message type are values instead of pointers. + - Getters are only generated for message and oneof fields. + - Enum types do not get an Enum method. + +Consider file test.proto, containing + +```proto + package example; + + enum FOO { X = 17; }; + + message Test { + required string label = 1; + optional int32 type = 2 [default=77]; + repeated int64 reps = 3; + optional group OptionalGroup = 4 { + required string RequiredField = 5; + } + } +``` + +To create and play with a Test object from the example package, + +```go + package main + + import ( + "log" + + "github.com/golang/protobuf/proto" + "path/to/example" + ) + + func main() { + test := &example.Test { + Label: proto.String("hello"), + Type: proto.Int32(17), + Reps: []int64{1, 2, 3}, + Optionalgroup: &example.Test_OptionalGroup { + RequiredField: proto.String("good bye"), + }, + } + data, err := proto.Marshal(test) + if err != nil { + log.Fatal("marshaling error: ", err) + } + newTest := &example.Test{} + err = proto.Unmarshal(data, newTest) + if err != nil { + log.Fatal("unmarshaling error: ", err) + } + // Now test and newTest contain the same data. + if test.GetLabel() != newTest.GetLabel() { + log.Fatalf("data mismatch %q != %q", test.GetLabel(), newTest.GetLabel()) + } + // etc. + } +``` + +## Parameters ## + +To pass extra parameters to the plugin, use a comma-separated +parameter list separated from the output directory by a colon: + + + protoc --go_out=plugins=grpc,import_path=mypackage:. *.proto + + +- `import_prefix=xxx` - a prefix that is added onto the beginning of + all imports.

This is great, but the problem is if +you have configuration or an encoding that changes slightly depending on +specific fields. For example, consider this JSON: + +```json +{ + "type": "person", + "name": "Mitchell" +} +``` + +Perhaps we can't populate a specific structure without first reading +the "type" field from the JSON. We could always do two passes over the +decoding of the JSON (reading the "type" first, and the rest later). +However, it is much simpler to just decode this into a `map[string]interface{}` +structure, read the "type" key, then use something like this library +to decode it into the proper structure. diff --git a/vendor/github.com/ncw/swift/README.md b/vendor/github.com/ncw/swift/README.md new file mode 100644 index 00000000..2cc24cff --- /dev/null +++ b/vendor/github.com/ncw/swift/README.md @@ -0,0 +1,140 @@ +Swift +===== + +This package provides an easy to use library for interfacing with +Swift / Openstack Object Storage / Rackspace cloud files from the Go +Language + +See here for package docs + + http://godoc.org/github.com/ncw/swift + +[![Build Status](https://api.travis-ci.org/ncw/swift.svg?branch=master)](https://travis-ci.org/ncw/swift) [![GoDoc](https://godoc.org/github.com/ncw/swift?status.svg)](https://godoc.org/github.com/ncw/swift) + +Install +------- + +Use go to install the library + + go get github.com/ncw/swift + +Usage +----- + +See here for full package docs + +- http://godoc.org/github.com/ncw/swift + +Here is a short example from the docs + + import "github.com/ncw/swift" + + // Create a connection + c := swift.Connection{ + UserName: "user", + ApiKey: "key", + AuthUrl: "auth_url", + Domain: "domain", // Name of the domain (v3 auth only) + Tenant: "tenant", // Name of the tenant (v2 auth only) + } + // Authenticate + err := c.Authenticate() + if err != nil { + panic(err) + } + // List all the containers + containers, err := c.ContainerNames(nil) + fmt.Println(containers) + // etc... + +Additions +--------- + +The `rs` sub project contains a wrapper for the Rackspace specific CDN Management interface. + +Testing +------- + +To run the tests you can either use an embedded fake Swift server +either use a real Openstack Swift server or a Rackspace Cloud files account. + +When using a real Swift server, you need to set these environment variables +before running the tests + + export SWIFT_API_USER='user' + export SWIFT_API_KEY='key' + export SWIFT_AUTH_URL='https://url.of.auth.server/v1.0' + +And optionally these if using v2 authentication + + export SWIFT_TENANT='TenantName' + export SWIFT_TENANT_ID='TenantId' + +And optionally these if using v3 authentication + + export SWIFT_TENANT='TenantName' + export SWIFT_TENANT_ID='TenantId' + export SWIFT_API_DOMAIN_ID='domain id' + export SWIFT_API_DOMAIN='domain name' + +And optionally these if using v3 trust + + export SWIFT_TRUST_ID='TrustId' + +And optionally this if you want to skip server certificate validation + + export SWIFT_AUTH_INSECURE=1 + +And optionally this to configure the connect channel timeout, in seconds + + export SWIFT_CONNECTION_CHANNEL_TIMEOUT=60 + +And optionally this to configure the data channel timeout, in seconds + + export SWIFT_DATA_CHANNEL_TIMEOUT=60 + +Then run the tests with `go test` + +License +------- + +This is free software under the terms of MIT license (check COPYING file +included in this package). + +Contact and support +------------------- + +The project website is at: + +- https://github.com/ncw/swift + +There you can file bug reports, ask for help or contribute patches. + +Authors +------- + +- Nick Craig-Wood + +Contributors +------------ + +- Brian "bojo" Jones +- Janika Liiv +- Yamamoto, Hirotaka +- Stephen +- platformpurple +- Paul Querna +- Livio Soares +- thesyncim +- lsowen +- Sylvain Baubeau +- Chris Kastorff +- Dai HaoJun +- Hua Wang +- Fabian Ruff +- Arturo Reuschenbach Puncernau +- Petr Kotek +- Stefan Majewsky +- Cezar Sa Espinola +- Sam Gunaratne +- Richard Scothern diff --git a/vendor/github.com/opencontainers/go-digest/LICENSE.code b/vendor/github.com/opencontainers/go-digest/LICENSE.code new file mode 100644 index 00000000..0ea3ff81 --- /dev/null +++ b/vendor/github.com/opencontainers/go-digest/LICENSE.code @@ -0,0 +1,191 @@ + + Apache License + Version 2.0, January 2004 + https://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

This allows two disparate applications +to agree on a verifiable identifier without having to trust one +another. + +An identifying digest can be verified, as follows: + +```go +if id != digest.FromBytes([]byte("my content")) { + return errors.New("the content has changed!") +} +``` + +A `Verifier` type can be used to handle cases where an `io.Reader` +makes more sense: + +```go +rd := getContent() +verifier := id.Verifier() +io.Copy(verifier, rd) + +if !verifier.Verified() { + return errors.New("the content has changed!") +} +``` + +Using [Merkle DAGs](https://en.wikipedia.org/wiki/Merkle_tree), this +can power a rich, safe, content distribution system. + +# Usage + +While the [godoc](https://godoc.org/github.com/docker/go-digest) is +considered the best resource, a few important items need to be called +out when using this package. + +1. Make sure to import the hash implementations into your application + or the package will panic. You should have something like the + following in the main (or other entrypoint) of your application: + + ```go + import ( + _ "crypto/sha256" + _ "crypto/sha512" + ) + ``` + This may seem inconvenient but it allows you replace the hash + implementations with others, such as https://github.com/stevvooe/resumable. + +2. Even though `digest.Digest` may be assemable as a string, _always_ + verify your input with `digest.Parse` or use `Digest.Validate` + when accepting untrusted input. While there are measures to + avoid common problems, this will ensure you have valid digests + in the rest of your application. + +# Stability + +The Go API, at this stage, is considered stable, unless otherwise noted. + +As always, before using a package export, read the [godoc](https://godoc.org/github.com/docker/go-digest). + +# Contributing + +This package is considered fairly complete. It has been in production +in thousands (millions?) of deployments and is fairly battle-hardened. +New additions will be met with skepticism.

In addition to providing an interface, Cobra +simultaneously provides a controller to organize your application code. + +Inspired by go, go-Commander, gh and subcommand, Cobra improves on these by +providing **fully posix compliant flags** (including short & long versions), +**nesting commands**, and the ability to **define your own help and usage** for any or +all commands. + +Cobra has an exceptionally clean interface and simple design without needless +constructors or initialization methods. + +Applications built with Cobra commands are designed to be as user friendly as +possible. Flags can be placed before or after the command (as long as a +confusing space isn’t provided). Both short and long flags can be used. A +command need not even be fully typed. The shortest unambiguous string will +suffice. Help is automatically generated and available for the application or +for a specific command using either the help command or the --help flag. + +## Concepts + +Cobra is built on a structure of commands & flags. + +**Commands** represent actions and **Flags** are modifiers for those actions. + +In the following example 'server' is a command and 'port' is a flag. + + hugo server --port=1313 + +### Commands + +Command is the central point of the application. Each interaction that +the application supports will be contained in a Command. A command can +have children commands and optionally run an action. + +In the example above 'server' is the command + +A Command has the following structure: + + type Command struct { + Use string // The one-line usage message. + Short string // The short description shown in the 'help' output. + Long string // The long message shown in the 'help ' output. + Run func(cmd *Command, args []string) // Run runs the command. + } + +### Flags + +A Flag is a way to modify the behavior of an command. Cobra supports +fully posix compliant flags as well as the go flag package. +A Cobra command can define flags that persist through to children commands +and flags that are only available to that command. + +In the example above 'port' is the flag. + +Flag functionality is provided by the [pflag +library](https://github.com/ogier/pflag), a fork of the flag standard library +which maintains the same interface while adding posix compliance. + +## Usage + +Cobra works by creating a set of commands and then organizing them into a tree. +The tree defines the structure of the application. + +Once each command is defined with it's corresponding flags, then the +tree is assigned to the commander which is finally executed. + +### Installing +Using Cobra is easy. First use go get to install the latest version +of the library. + + $ go get github.com/spf13/cobra + +Next include cobra in your application. + + import "github.com/spf13/cobra" + +### Create the root command + +The root command represents your binary itself. + +Cobra doesn't require any special constructors.

For +global flags assign a flag as a persistent flag on the root. + + HugoCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output") + +#### Local Flags + +A flag can also be assigned locally which will only apply to that specific command. + + HugoCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from") + +### Remove a command from its parent + +Removing a command is not a common action in simple programs but it allows 3rd parties to customize an existing command tree. + +In this example, we remove the existing `VersionCmd` command of an existing root command, and we replace it by our own version. + + mainlib.RootCmd.RemoveCommand(mainlib.VersionCmd) + mainlib.RootCmd.AddCommand(versionCmd) + +### Once all commands and flags are defined, Execute the commands + +Execute should be run on the root for clarity, though it can be called on any command. + + HugoCmd.Execute() + +## Example + +In the example below we have defined three commands.

For a more precise description, see the +"Command-line flag syntax" section below. + +[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html + +pflag is available under the same style of BSD license as the Go language, +which can be found in the LICENSE file. + +## Installation + +pflag is available using the standard `go get` command. + +Install by running: + + go get github.com/ogier/pflag + +Run tests by running: + + go test github.com/ogier/pflag + +## Usage + +pflag is a drop-in replacement of Go's native flag package. If you import +pflag under the name "flag" then all code should continue to function +with no changes. + +``` go +import flag "github.com/ogier/pflag" +``` + +There is one exception to this: if you directly instantiate the Flag struct +there is one more field "Shorthand" that you will need to set. +Most code never instantiates this struct directly, and instead uses +functions such as String(), BoolVar(), and Var(), and is therefore +unaffected. + +Define flags using flag.String(), Bool(), Int(), etc. + +This declares an integer flag, -flagname, stored in the pointer ip, with type *int. + +``` go +var ip *int = flag.Int("flagname", 1234, "help message for flagname") +``` + +If you like, you can bind the flag to a variable using the Var() functions. + +``` go +var flagvar int +func init() { + flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname") +} +``` + +Or you can create custom flags that satisfy the Value interface (with +pointer receivers) and couple them to flag parsing by + +``` go +flag.Var(&flagVal, "name", "help message for flagname") +``` + +For such flags, the default value is just the initial value of the variable. + +After all flags are defined, call + +``` go +flag.Parse() +``` + +to parse the command line into the defined flags. + +Flags may then be used directly. If you're using the flags themselves, +they are all pointers; if you bind to variables, they're values. + +``` go +fmt.Println("ip has value ", *ip) +fmt.Println("flagvar has value ", flagvar) +``` + +After parsing, the arguments after the flag are available as the +slice flag.Args() or individually as flag.Arg(i). +The arguments are indexed from 0 through flag.NArg()-1. + +The pflag package also defines some new functions that are not in flag, +that give one-letter shorthands for flags. You can use these by appending +'P' to the name of any function that defines a flag. + +``` go +var ip = flag.IntP("flagname", "f", 1234, "help message") +var flagvar bool +func init() { + flag.BoolVarP("boolname", "b", true, "help message") +} +flag.VarP(&flagVar, "varname", "v", 1234, "help message") +``` + +Shorthand letters can be used with single dashes on the command line. +Boolean shorthand flags can be combined with other shorthand flags. + +The default set of command-line flags is controlled by +top-level functions. The FlagSet type allows one to define +independent sets of flags, such as to implement subcommands +in a command-line interface. The methods of FlagSet are +analogous to the top-level functions for the command-line +flag set. + +## Command line flag syntax + +``` +--flag // boolean flags only +--flag=x +``` + +Unlike the flag package, a single dash before an option means something +different than a double dash. Single dashes signify a series of shorthand +letters for flags. All but the last shorthand letter must be boolean flags. + +``` +// boolean flags +-f +-abc + +// non-boolean flags +-n 1234 +-Ifile + +// mixed +-abcs "hello" +-abcn1234 +``` + +Flag parsing stops after the terminator "--". Unlike the flag package, +flags can be interspersed with arguments anywhere on the command line +before this terminator. + +Integer flags accept 1234, 0664, 0x1234 and may be negative. +Boolean flags (in their long form) accept 1, 0, t, f, true, false, +TRUE, FALSE, True, False. +Duration flags accept any input valid for time.ParseDuration. + +## Mutating or "Normalizing" Flag names + +It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow. + +**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag + +```go +func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName { + from := []string{"-", "_"} + to := "." + for _, sep := range from { + name = strings.Replace(name, sep, to, -1) + } + return pflag.NormalizedName(name) +} + +myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc) +``` + +**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name + +```go +func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName { + switch name { + case "old-flag-name": + name = "new-flag-name" + break + } + return pflag.NormalizedName(name) +} + +myFlagSet.SetNormalizeFunc(aliasNormalizeFunc) +``` + +## More info + +You can see the full reference documentation of the pflag package +[at godoc.org][3], or through go's standard documentation system by +running `godoc -http=:6060` and browsing to +[http://localhost:6060/pkg/github.com/ogier/pflag][2] after +installation. + +[2]: http://localhost:6060/pkg/github.com/ogier/pflag +[3]: http://godoc.org/github.com/ogier/pflag diff --git a/vendor/github.com/stevvooe/resumable/README.md b/vendor/github.com/stevvooe/resumable/README.md new file mode 100644 index 00000000..d2d3fb89 --- /dev/null +++ b/vendor/github.com/stevvooe/resumable/README.md @@ -0,0 +1,6 @@ +# go-crypto +A Subset of the Go `crypto` Package with a Resumable Hash Interface + +### Documentation + +GoDocs: http://godoc.org/github.com/stevvooe/resumable diff --git a/vendor/github.com/xenolf/lego/README.md b/vendor/github.com/xenolf/lego/README.md new file mode 100644 index 00000000..ff692132 --- /dev/null +++ b/vendor/github.com/xenolf/lego/README.md @@ -0,0 +1,248 @@ +# lego +Let's Encrypt client and ACME library written in Go + +[![GoDoc](https://godoc.org/github.com/xenolf/lego/acme?status.svg)](https://godoc.org/github.com/xenolf/lego/acme) +[![Build Status](https://travis-ci.org/xenolf/lego.svg?branch=master)](https://travis-ci.org/xenolf/lego) +[![Dev Chat](https://img.shields.io/badge/dev%20chat-gitter-blue.svg?label=dev+chat)](https://gitter.im/xenolf/lego) + +#### General +This is a work in progress.

I don't run this code +anymore: to simplify maintenance, I moved the sites off of Ubuntu VMs and +onto Google App Engine, configured with inexpensive long-term certificates +purchased from cheapsslsecurity.com. + +This package was interesting primarily as an example of how simple the API +for using LetsEncrypt.org could be made, in contrast to the low-level +implementations that existed at the time. In that respect, it helped inform +the design of the golang.org/x/crypto/acme/autocert package. + + +Quick Start + +A complete HTTP/HTTPS web server using TLS certificates from +LetsEncrypt.org, redirecting all HTTP access to HTTPS, and maintaining TLS +certificates in a file letsencrypt.cache across server restarts. + + package main + + import ( + "fmt" + "log" + "net/http" + "rsc.io/letsencrypt" + ) + + func main() { + http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { + fmt.Fprintf(w, "Hello, TLS!\n") + }) + var m letsencrypt.Manager + if err := m.CacheFile("letsencrypt.cache"); err != nil { + log.Fatal(err) + } + log.Fatal(m.Serve()) + } + + +Overview + +The fundamental type in this package is the Manager, which manages obtaining +and refreshing a collection of TLS certificates, typically for use by an +HTTPS server. The example above shows the most basic use of a Manager. The +use can be customized by calling additional methods of the Manager. + + +Registration + +A Manager m registers anonymously with LetsEncrypt.org, including agreeing +to the letsencrypt.org terms of service, the first time it needs to obtain a +certificate. To register with a particular email address and with the option +of a prompt for agreement with the terms of service, call m.Register. + + +GetCertificate + +The Manager's GetCertificate method returns certificates from the Manager's +cache, filling the cache by requesting certificates from LetsEncrypt.org. In +this way, a server with a tls.Config.GetCertificate set to m.GetCertificate +will demand load a certificate for any host name it serves. To force loading +of certificates ahead of time, install m.GetCertificate as before but then +call m.Cert for each host name. + +A Manager can only obtain a certificate for a given host name if it can +prove control of that host name to LetsEncrypt.org. By default it proves +control by answering an HTTPS-based challenge: when the LetsEncrypt.org +servers connect to the named host on port 443 (HTTPS), the TLS SNI handshake +must use m.GetCertificate to obtain a per-host certificate. The most common +way to satisfy this requirement is for the host name to resolve to the IP +address of a (single) computer running m.ServeHTTPS, or at least running a +Go TLS server with tls.Config.GetCertificate set to m.GetCertificate. +However, other configurations are possible. For example, a group of machines +could use an implementation of tls.Config.GetCertificate that cached +certificates but handled cache misses by making RPCs to a Manager m on an +elected leader machine. + +In typical usage, then, the setting of tls.Config.GetCertificate to +m.GetCertificate serves two purposes: it provides certificates to the TLS +server for ordinary serving, and it also answers challenges to prove +ownership of the domains in order to obtain those certificates. + +To force the loading of a certificate for a given host into the Manager's +cache, use m.Cert. + + +Persistent Storage + +If a server always starts with a zero Manager m, the server effectively +fetches a new certificate for each of its host name from LetsEncrypt.org on +each restart. This is unfortunate both because the server cannot start if +LetsEncrypt.org is unavailable and because LetsEncrypt.org limits how often +it will issue a certificate for a given host name (at time of writing, the +limit is 5 per week for a given host name). To save server state proactively +to a cache file and to reload the server state from that same file when +creating a new manager, call m.CacheFile with the name of the file to use. + +For alternate storage uses, m.Marshal returns the current state of the +Manager as an opaque string, m.Unmarshal sets the state of the Manager using +a string previously returned by m.Marshal (usually a different m), and +m.Watch returns a channel that receives notifications about state changes. + + +Limits + +To avoid hitting basic rate limits on LetsEncrypt.org, a given Manager +limits all its interactions to at most one request every minute, with an +initial allowed burst of 20 requests. + +By default, if GetCertificate is asked for a certificate it does not have, +it will in turn ask LetsEncrypt.org for that certificate. This opens a +potential attack where attackers connect to a server by IP address and +pretend to be asking for an incorrect host name. Then GetCertificate will +attempt to obtain a certificate for that host, incorrectly, eventually +hitting LetsEncrypt.org's rate limit for certificate requests and making it +impossible to obtain actual certificates. Because servers hold certificates +for months at a time, however, an attack would need to be sustained over a +time period of at least a month in order to cause real problems. + +To mitigate this kind of attack, a given Manager limits itself to an average +of one certificate request for a new host every three hours, with an initial +allowed burst of up to 20 requests. Long-running servers will therefore stay +within the LetsEncrypt.org limit of 300 failed requests per month. +Certificate refreshes are not subject to this limit. + +To eliminate the attack entirely, call m.SetHosts to enumerate the exact set +of hosts that are allowed in certificate requests. + + +Web Servers + +The basic requirement for use of a Manager is that there be an HTTPS server +running on port 443 and calling m.GetCertificate to obtain TLS certificates. +Using standard primitives, the way to do this is: + + srv := &http.Server{ + Addr: ":https", + TLSConfig: &tls.Config{ + GetCertificate: m.GetCertificate, + }, + } + srv.ListenAndServeTLS("", "") + +However, this pattern of serving HTTPS with demand-loaded TLS certificates +comes up enough to wrap into a single method m.ServeHTTPS. + +Similarly, many HTTPS servers prefer to redirect HTTP clients to the HTTPS +URLs. That functionality is provided by RedirectHTTP. + +The combination of serving HTTPS with demand-loaded TLS certificates and +serving HTTPS redirects to HTTP clients is provided by m.Serve, as used in +the original example above. + +func RedirectHTTP(w http.ResponseWriter, r *http.Request) +type Manager struct { ... }
