 This project provides various Go packages to perform operations
 on Microsoft Azure REST APIs.
 [![GoDoc](https://godoc.org/github.com/Azure/azure-sdk-for-go?status.svg)](https://godoc.org/github.com/Azure/azure-sdk-for-go) [![Build Status](https://travis-ci.org/Azure/azure-sdk-for-go.svg?branch=master)](https://travis-ci.org/Azure/azure-sdk-for-go)
 See list of implemented API clients [here](http://godoc.org/github.com/Azure/azure-sdk-for-go).
 > **NOTE:** This repository is under heavy ongoing development and
 is likely to break over time. We currently do not have any releases
 yet. If you are planning to use the repository, please consider vendoring
 the packages in your project and update them when a stable tag is out.
 # Installation
    go get -d github.com/Azure/azure-sdk-for-go/management
 # Usage
 Read Godoc of the repository at: http://godoc.org/github.com/Azure/azure-sdk-for-go/
 The client currently supports authentication to the Service Management
 API with certificates or Azure `.publishSettings` file. You can 
 download the `.publishSettings` file for your subscriptions
 [here](https://manage.windowsazure.com/publishsettings).

 # Papertrail Hook for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:" />
 [Papertrail](https://papertrailapp.com) provides hosted log management. Once stored in Papertrail, you can [group](http://help.papertrailapp.com/kb/how-it-works/groups/) your logs on various dimensions, [search](http://help.papertrailapp.com/kb/how-it-works/search-syntax) them, and trigger [alerts](http://help.papertrailapp.com/kb/how-it-works/alerts).
 In most deployments, you'll want to send logs to Papertrail via their [remote_syslog](http://help.papertrailapp.com/kb/configuration/configuring-centralized-logging-from-text-log-files-in-unix/) daemon, which requires no application-specific configuration. This hook is intended for relatively low-volume logging, likely in managed cloud hosting deployments where installing `remote_syslog` is not possible.
 ## Usage
 You can find your Papertrail UDP port on your [Papertrail account page](https://papertrailapp.com/account/destinations). Substitute it below for `YOUR_PAPERTRAIL_UDP_PORT`.
 For `YOUR_APP_NAME`, substitute a short string that will readily identify your application or service in the logs.
 ```go
 import (
  "log/syslog"
  "github.com/Sirupsen/logrus"
  "github.com/Sirupsen/logrus/hooks/papertrail"
 )
 func main() {
  log       := logrus.New()
  hook, err := logrus_papertrail.NewPapertrailHook("logs.papertrailapp.com", YOUR_PAPERTRAIL_UDP_PORT, YOUR_APP_NAME)
  if err == nil {
    log.Hooks.Add(hook)
  }
 }
 ```

 # Sentry Hook for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:" />
 [Sentry](https://getsentry.com) provides both self-hosted and hosted
 solutions for exception tracking.
 Both client and server are
 [open source](https://github.com/getsentry/sentry).
 ## Usage
 Every sentry application defined on the server gets a different
 [DSN](https://www.getsentry.com/docs/). In the example below replace
 `YOUR_DSN` with the one created for your application.
 ```go
 import (
  "github.com/Sirupsen/logrus"
  "github.com/Sirupsen/logrus/hooks/sentry"
 )
 func main() {
  log       := logrus.New()
  hook, err := logrus_sentry.NewSentryHook(YOUR_DSN, []logrus.Level{
    logrus.PanicLevel,
    logrus.FatalLevel,
    logrus.ErrorLevel,
  })
  if err == nil {
    log.Hooks.Add(hook)
  }
 }
 ```
 ## Special fields
 Some logrus fields have a special meaning in this hook,
 these are server_name and logger.
 When logs are sent to sentry these fields are treated differently.
 - server_name (also known as hostname) is the name of the server which
 is logging the event (hostname.example.com)
 - logger is the part of the application which is logging the event.
 In go this usually means setting it to the name of the package.
 ## Timeout
 `Timeout` is the time the sentry hook will wait for a response
 from the sentry server.
 If this time elapses with no response from
 the server an error will be returned.
 If `Timeout` is set to 0 the SentryHook will not wait for a reply
 and will assume a correct delivery.
 The SentryHook has a default timeout of `100 milliseconds` when created
 with a call to `NewSentryHook`. This can be changed by assigning a value to the `Timeout` field:
 ```go
 hook, _ := logrus_sentry.NewSentryHook(...)
 hook.Timeout = 20*time.Second
 ```

 # h2i
 **h2i** is an interactive HTTP/2 ("h2") console debugger. Miss the good ol'
 days of telnetting to your HTTP/1.n servers? We're bringing you
 back.
 Features:
 - send raw HTTP/2 frames
 - PING
 - SETTINGS
 - HEADERS
 - etc
 - type in HTTP/1.n and have it auto-HPACK/frame-ify it for HTTP/2
 - pretty print all received HTTP/2 frames from the peer (including HPACK decoding)
 - tab completion of commands, options
 Not yet features, but soon:
 - unnecessary CONTINUATION frames on short boundaries, to test peer implementations 
 - request bodies (DATA frames)
 - send invalid frames for testing server implementations (supported by underlying Framer)
 Later:
 - act like a server
 ## Installation
 ```
 $ go get github.com/bradfitz/http2/h2i
 $ h2i <host>
 ```
 ## Demo

 ## Status
 Quick few hour hack. So much yet to do. Feel free to file issues for
 bugs or wishlist items, but [@bmizerany](https://github.com/bmizerany/)
 and I aren't yet accepting pull requests until things settle down.

 ## Libtrust TLS Config Demo
 This program generates key pairs and trust files for a TLS client and server.
 To generate the keys, run:
 ```
 $ go run genkeys.go
 ```
 The generated files are:
 ```
 $ ls -l client_data/ server_data/
 client_data/:
 total 24
 -rw-------  1 jlhawn  staff  281 Aug  8 16:21 private_key.json
 -rw-r--r--  1 jlhawn  staff  225 Aug  8 16:21 public_key.json
 -rw-r--r--  1 jlhawn  staff  275 Aug  8 16:21 trusted_hosts.json
 server_data/:
 total 24
 -rw-r--r--  1 jlhawn  staff  348 Aug  8 16:21 trusted_clients.json
 -rw-------  1 jlhawn  staff  281 Aug  8 16:21 private_key.json
 -rw-r--r--  1 jlhawn  staff  225 Aug  8 16:21 public_key.json
 ```
 The private key and public key for the client and server are stored in `private_key.json` and `public_key.json`, respectively, and in their respective directories. They are represented as JSON Web Keys: JSON objects which represent either an ECDSA or RSA private key. The host keys trusted by the client are stored in `trusted_hosts.json` and contain a mapping of an internet address, `<HOSTNAME_OR_IP>:<PORT>`, to a JSON Web Key which is a JSON object representing either an ECDSA or RSA public key of the trusted server. The client keys trusted by the server are stored in `trusted_clients.json` and contain an array of JSON objects which contain a comment field which can be used describe the key and a JSON Web Key which is a JSON object representing either an ECDSA or RSA public key of the trusted client.
 To start the server, run:
 ```
 $ go run server.go
 ```
 This starts an HTTPS server which listens on `localhost:8888`. The server configures itself with a certificate which is valid for both `localhost` and `127.0.0.1` and uses the key from `server_data/private_key.json`. It accepts connections from clients which present a certificate for a key that it is configured to trust from the `trusted_clients.json` file and returns a simple 'hello' message.
 To make a request using the client, run:
 ```
 $ go run client.go
 ```
 This command creates an HTTPS client which makes a GET request to `https://localhost:8888`. The client configures itself with a certificate using the key from `client_data/private_key.json`. It only connects to a server which presents a certificate signed by the key specified for the `localhost:8888` address from `client_data/trusted_hosts.json` and made to be used for the `localhost` hostname. If the connection succeeds, it prints the response from the server.
 The file `gencert.go` can be used to generate PEM encoded version of the client key and certificate. If you save them to `key.pem` and `cert.pem` respectively, you can use them with `curl` to test out the server (if it is still running).
 ```
 curl --cert cert.pem --key key.pem -k https://localhost:8888
 ```
