From a685e3fc98df24ff9d5b243de03cc8a5c4598d5e Mon Sep 17 00:00:00 2001 From: Derek McGowan Date: Wed, 23 Nov 2016 15:07:06 -0800 Subject: [PATCH 1/2] Replace godep with vndr Vndr has a simpler configuration and allows pointing to forked packages. Additionally other docker projects are now using vndr making vendoring in distribution more consistent. Updates letsencrypt to use fork. No longer uses sub-vendored packages.

You can customize it all you -want: - -```go -package main - -import ( - "os" - log "github.com/Sirupsen/logrus" - "github.com/Sirupsen/logrus/hooks/airbrake" -) - -func init() { - // Log as JSON instead of the default ASCII formatter. - log.SetFormatter(&log.JSONFormatter{}) - - // 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("https://example.com", "xyz", "development")) - - // 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" - "github.com/Sirupsen/logrus/hooks/airbrake" - "github.com/Sirupsen/logrus/hooks/syslog" - "log/syslog" -) - -func init() { - log.AddHook(airbrake.NewHook("https://example.com", "xyz", "development")) - - 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) - } -} -``` - - -| Hook | Description | -| ----- | ----------- | -| [Airbrake](https://github.com/Sirupsen/logrus/blob/master/hooks/airbrake/airbrake.go) | Send errors to an exception tracking service compatible with the Airbrake API. Uses [`airbrake-go`](https://github.com/tobi/airbrake-go) behind the scenes. | -| [Papertrail](https://github.com/Sirupsen/logrus/blob/master/hooks/papertrail/papertrail.go) | Send errors to the Papertrail hosted logging service via UDP. | -| [Syslog](https://github.com/Sirupsen/logrus/blob/master/hooks/syslog/syslog.go) | Send errors to remote syslog server. Uses standard library `log/syslog` behind the scenes. | -| [BugSnag](https://github.com/Sirupsen/logrus/blob/master/hooks/bugsnag/bugsnag.go) | Send errors to the Bugsnag exception tracking service. | -| [Hiprus](https://github.com/nubo/hiprus) | Send errors to a channel in hipchat. | -| [Logrusly](https://github.com/sebest/logrusly) | Send logs to [Loggly](https://www.loggly.com/) | -| [Slackrus](https://github.com/johntdyer/slackrus) | Hook for Slack chat. | -| [Journalhook](https://github.com/wercker/journalhook) | Hook for logging to `systemd-journald` | -| [Graylog](https://github.com/gemnasium/logrus-hooks/tree/master/graylog) | Hook for logging to [Graylog](http://graylog2.org/) | - -#### 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(logrus.JSONFormatter) - } else { - // The TextFormatter is default, you don't actually have to do this. - log.SetFormatter(logrus.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. -* `logrus_logstash.LogstashFormatter`. Logs fields as Logstash Events (http://logstash.net). - - ```go - logrus.SetFormatter(&logrus_logstash.LogstashFormatter{Type: “application_name"}) - ``` - -Third party logging formatters: - -* [`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 *JSONFormatter) 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 transormed 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. - - -[godoc]: https://godoc.org/github.com/Sirupsen/logrus diff --git a/vendor/github.com/aws/aws-sdk-go/LICENSE.txt b/vendor/github.com/aws/aws-sdk-go/LICENSE.txt deleted file mode 100644 index d64569567..000000000 --- a/vendor/github.com/aws/aws-sdk-go/LICENSE.txt +++ /dev/null @@ -1,202 +0,0 @@ - - Apache License - Version 2.0, January 2004 - http://www.apache.org/licenses/ - - TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION - - 1.

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

-如果获取到的值不是候选值的任意一个，则会返回默认值，而默认值不需要是候选值中的一员。 - -验证获取的值是否在指定范围内： - -```go -vals = cfg.Section("").Key("FLOAT64").RangeFloat64(0.0, 1.1, 2.2) -vals = cfg.Section("").Key("INT").RangeInt(0, 10, 20) -vals = cfg.Section("").Key("INT64").RangeInt64(0, 10, 20) -vals = cfg.Section("").Key("UINT").RangeUint(0, 3, 9) -vals = cfg.Section("").Key("UINT64").RangeUint64(0, 3, 9) -vals = cfg.Section("").Key("TIME").RangeTimeFormat(time.RFC3339, time.Now(), minTime, maxTime) -vals = cfg.Section("").Key("TIME").RangeTime(time.Now(), minTime, maxTime) // RFC3339 -``` - -自动分割键值为切片（slice）： - -```go -vals = cfg.Section("").Key("STRINGS").Strings(",") -vals = cfg.Section("").Key("FLOAT64S").Float64s(",") -vals = cfg.Section("").Key("INTS").Ints(",") -vals = cfg.Section("").Key("INT64S").Int64s(",") -vals = cfg.Section("").Key("UINTS").Uints(",") -vals = cfg.Section("").Key("UINT64S").Uint64s(",") -vals = cfg.Section("").Key("TIMES").Times(",") -``` - -### 保存配置 - -终于到了这个时刻，是时候保存一下配置了。 - -比较原始的做法是输出配置到某个文件： - -```go -// ... -err = cfg.SaveTo("my.ini") -err = cfg.SaveToIndent("my.ini", "\t") -``` - -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") -``` - -### 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 -``` - -#### 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:"|"` - Places []string - None []int -} - -type Author struct { - Name string `ini:"NAME"` - Male bool - Age int - GPA float64 - NeverMind string `ini:"-"` - *Embeded -} - -func main() { - a := &Author{"Unknwon", true, 21, 2.8, "", - &Embeded{ - []time.Time{time.Now(), time.Now()}, - []string{"HangZhou", "Boston"}, - []int{}, - }} - cfg := ini.Empty() - 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 -None = -``` - -#### 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("packag_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。 - -#### 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) - -## 常见问题 - -### 字段 `BlockMode` 是什么？ - -默认情况下，本库会在您进行读写操作时采用锁机制来确保数据时间。但在某些情况下，您非常确定只进行读操作。此时，您可以通过设置 `cfg.BlockMode = false` 来将读操作提升大约 **50-70%** 的性能。 - -### 为什么要写另一个 INI 解析库？ - -许多人都在使用我的 [goconfig](https://github.com/Unknwon/goconfig) 来完成对 INI 文件的操作，但我希望使用更加 Go 风格的代码。并且当您设置 `cfg.BlockMode = false` 时，会有大约 **10-30%** 的性能提升。 - -为了做出这些改变，我必须对 API 进行破坏，所以新开一个仓库是最安全的做法。除此之外，本库直接使用 `gopkg.in` 来进行版本化发布。（其实真相是导入路径更短了） diff --git a/vendor/github.com/aws/aws-sdk-go/vendor/github.com/go-ini/ini/ini.go b/vendor/github.com/aws/aws-sdk-go/vendor/github.com/go-ini/ini/ini.go deleted file mode 100644 index 1fee789a1..000000000 --- a/vendor/github.com/aws/aws-sdk-go/vendor/github.com/go-ini/ini/ini.go +++ /dev/null @@ -1,1226 +0,0 @@ -// Copyright 2014 Unknwon -// -// Licensed under the Apache License, Version 2.0 (the "License"): you may -// not use this file except in compliance with the License.

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. Wrap your server in a [bugsnag.Handler](https://godoc.org/github.com/bugsnag/bugsnag-go/#Handler) - - ```go - // a. If you're using the builtin http mux, you can just pass - // bugsnag.Handler(nil) to http.ListenAndServer - http.ListenAndServe(":8080", bugsnag.Handler(nil)) - - // b. If you're creating a server manually yourself, you can set - // its handlers the same way - srv := http.Server{ - Handler: bugsnag.Handler(nil) - } - - // c. If you're not using the builtin http mux, wrap your own handler - // (though make sure that it doesn't already catch panics) - http.ListenAndServe(":8080", bugsnag.Handler(handler)) - ``` - -### Using with Revel apps - -There are two steps to get panic handling in [revel](https://revel.github.io) apps. - -1. 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 deleted file mode 100644 index 8d8e097aa..000000000 --- a/vendor/github.com/bugsnag/bugsnag-go/errors/README.md +++ /dev/null @@ -1,6 +0,0 @@ -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 deleted file mode 100644 index d0a596753..000000000 --- a/vendor/github.com/bugsnag/panicwrap/README.md +++ /dev/null @@ -1,101 +0,0 @@ -# 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.

Just exit with the proper status. - if exitStatus >= 0 { - os.Exit(exitStatus) - } - - // Otherwise, exitStatus < 0 means we're the child.

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.

Currently only a few have been standardized: EDNS0_NSID +(RFC 5001) and EDNS0_SUBNET (draft-vandergaast-edns-client-subnet-02). Note +that these options may be combined in an OPT RR. +Basic use pattern for a server to check if (and which) options are set: + + // o is a dns.OPT + for _, s := range o.Option { + switch e := s.(type) { + case *dns.EDNS0_NSID: + // do stuff with e.Nsid + case *dns.EDNS0_SUBNET: + // access e.Family, e.Address, etc. + } + } + +SIG(0) + +From RFC 2931: + + SIG(0) provides protection for DNS transactions and requests .... + ... protection for glue records, DNS requests, protection for message headers + on requests and responses, and protection of the overall integrity of a response. + +It works like TSIG, except that SIG(0) uses public key cryptography, instead of the shared +secret approach in TSIG. +Supported algorithms: DSA, ECDSAP256SHA256, ECDSAP384SHA384, RSASHA1, RSASHA256 and +RSASHA512. + +Signing subsequent messages in multi-message sessions is not implemented. +*/ +package dns diff --git a/vendor/github.com/miekg/dns/edns.go b/vendor/github.com/miekg/dns/edns.go new file mode 100644 index 000000000..fc0b46925 --- /dev/null +++ b/vendor/github.com/miekg/dns/edns.go @@ -0,0 +1,597 @@ +package dns + +import ( + "encoding/binary" + "encoding/hex" + "errors" + "fmt" + "net" + "strconv" +) + +// EDNS0 Option codes. +const ( + EDNS0LLQ = 0x1 // long lived queries: http://tools.ietf.org/html/draft-sekar-dns-llq-01 + EDNS0UL = 0x2 // update lease draft: http://files.dns-sd.org/draft-sekar-dns-ul.txt + EDNS0NSID = 0x3 // nsid (RFC5001) + EDNS0DAU = 0x5 // DNSSEC Algorithm Understood + EDNS0DHU = 0x6 // DS Hash Understood + EDNS0N3U = 0x7 // NSEC3 Hash Understood + EDNS0SUBNET = 0x8 // client-subnet (RFC6891) + EDNS0EXPIRE = 0x9 // EDNS0 expire + EDNS0COOKIE = 0xa // EDNS0 Cookie + EDNS0TCPKEEPALIVE = 0xb // EDNS0 tcp keep alive (RFC7828) + EDNS0SUBNETDRAFT = 0x50fa // Don't use!

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.

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.

The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistendPostRun` and `PostRun` will be executed after `Run`.

Doing the above will cause `__custom_func()` to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`. `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`. So it will call `__kubectl_parse_get pod`. `__kubectl_parse_get` will actually call out to kubernetes and get any pods. It will then set `COMPREPLY` to valid pods! - -## Have the completions code complete your 'nouns' - -In the above example "pod" was assumed to already be typed. But if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them.

Doing so will give results like - -```bash -# kubectl get [tab][tab] -nodes pods replicationControllers services -``` - -## Mark flags as required - -Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab]. Marking a flag as 'Required' is incredibly easy. - -```go -cmd.MarkFlagRequired("pod") -cmd.MarkFlagRequired("container") -``` - -and you'll get something like - -```bash -# kubectl exec [tab][tab][tab] --c --container= -p --pod= -``` - -# Specify valid filename extensions for flags that take a filename - -In this example we use --filename= and expect to get a json or yaml file as the argument.

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.
