Fnlb/k8s grouper (#563)

Browse Source 
* WIP: add k8s grouper

- This shares a great deal of behaviour with allGrouper. Once it's
tested, refactor that to share as much as possible

- Glide hell. Checked in the yaml and lock files but a glide i -v
will be required to bring vendor/ up-to-date. Will address once this
is ready.

* Update README. Make the watch tracking work.

(To follow: add the junk that was pulled in via the glide update.)

* Vendor updates.

* go fmt

* Use the allGrouper with a k8s-backed DBStore instead.

This is much tidier :-)

* Fix up go vet

# Exponential Backoff [![GoDoc][godoc image]][godoc] [![Build Status][travis image]][travis] [![Coverage Status][coveralls image]][coveralls]
This is a Go port of the exponential backoff algorithm from [Google's HTTP Client Library for Java][google-http-java-client].
[Exponential backoff][exponential backoff wiki]
is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
in order to gradually find an acceptable rate.
The retries exponentially increase and stop increasing when a certain threshold is met.
## Usage
See https://godoc.org/github.com/cenkalti/backoff#pkg-examples
## Contributing
* I would like to keep this library as small as possible.
* Please don't send a PR without opening an issue and discussing it first.
* If proposed change is not a common use case, I will probably not accept it.

/*
ExponentialBackOff is a backoff implementation that increases the backoff
period for each retry attempt using a randomization function that grows exponentially.
NextBackOff() is calculated using the following formula:
randomized interval =
RetryInterval * (random value in range [1 - RandomizationFactor, 1 + RandomizationFactor])
In other words NextBackOff() will range between the randomization factor
percentage below and above the retry interval.
For example, given the following parameters:
RetryInterval = 2
RandomizationFactor = 0.5
Multiplier = 2
the actual backoff period used in the next retry attempt will range between 1 and 3 seconds,
multiplied by the exponential, that is, between 2 and 6 seconds.
Note: MaxInterval caps the RetryInterval and not the randomized interval.
If the time elapsed since an ExponentialBackOff instance is created goes past the
MaxElapsedTime, then the method NextBackOff() starts returning backoff.Stop.
The elapsed time can be reset by calling Reset().
Example: Given the following default arguments, for 10 tries the sequence will be,
and assuming we go over the MaxElapsedTime on the 10th try:
Request # RetryInterval (seconds) Randomized Interval (seconds)
1 0.5 [0.25, 0.75]
2 0.75 [0.375, 1.125]
3 1.125 [0.562, 1.687]
4 1.687 [0.8435, 2.53]
5 2.53 [1.265, 3.795]

7 5.692 [2.846, 8.538]
8 8.538 [4.269, 12.807]

# Sling Changelog
Notable changes between releases.
## Latest
## v1.1.0 (2016-12-19)
* Allow JSON decoding, regardless of response Content-Type (#26)
* Add `BodyProvider` interface and setter so request Body encoding can be customized (#23)
* Add `Doer` interface and setter so request sending behavior can be customized (#21)
* Add `SetBasicAuth` setter for Authorization headers (#16)
* Add Sling `Body` setter to set an `io.Reader` on the Request (#9)
## v1.0.0 (2015-05-23)
* Added support for receiving and decoding error JSON structs
* Renamed Sling `JsonBody` setter to `BodyJSON` (breaking)
* Renamed Sling `BodyStruct` setter to `BodyForm` (breaking)
* Renamed Sling fields `httpClient`, `method`, `rawURL`, and `header` to be internal (breaking)
* Changed `Do` and `Receive` to skip response JSON decoding if "application/json" Content-Type is missing
* Changed `Sling.Receive(v interface{})` to `Sling.Receive(successV, failureV interface{})` (breaking)
* Previously `Receive` attempted to decode the response Body in all cases
* Updated `Receive` will decode the response Body into successV for 2XX responses or decode the Body into failureV for other status codes. Pass a nil `successV` or `failureV` to skip JSON decoding into that value.
* To upgrade, pass nil for the `failureV` argument or consider defining a JSON tagged struct appropriate for the API endpoint. (e.g. `s.Receive(&issue, nil)`, `s.Receive(&issue, &githubError)`)
* To retain the old behavior, duplicate the first argument (e.g. s.Receive(&tweet, &tweet))
* Changed `Sling.Do(http.Request, v interface{})` to `Sling.Do(http.Request, successV, failureV interface{})` (breaking)
* See the changelog entry about `Receive`, the upgrade path is the same.
* Removed HEAD, GET, POST, PUT, PATCH, DELETE constants, no reason to export them (breaking)
## v0.4.0 (2015-04-26)
* Improved golint compliance
* Fixed typos and test printouts
## v0.3.0 (2015-04-21)
* Added BodyStruct method for setting a url encoded form body on the Request
* Added Add and Set methods for adding or setting Request Headers
* Added JsonBody method for setting JSON Request Body
* Improved examples and documentation
## v0.2.0 (2015-04-05)
* Added http.Client setter
* Added Sling.New() method to return a copy of a Sling
* Added Base setter and Path extension support
* Added method setters (Get, Post, Put, Patch, Delete, Head)
* Added support for encoding URL Query parameters
* Added example tiny Github API
* Changed v0.1.0 method signatures and names (breaking)
* Removed Go 1.0 support
## v0.1.0 (2015-04-01)
* Support decoding JSON responses.

# Sling [![Build Status](https://travis-ci.org/dghubble/sling.png?branch=master)](https://travis-ci.org/dghubble/sling) [![GoDoc](https://godoc.org/github.com/dghubble/sling?status.png)](https://godoc.org/github.com/dghubble/sling)
<img align="right" src="https://s3.amazonaws.com/dghubble/small-gopher-with-sling.png">
Sling is a Go HTTP client library for creating and sending API requests.
Slings store HTTP Request properties to simplify sending requests and decoding responses. Check [usage](#usage) or the [examples](examples) to learn how to compose a Sling into your API client.
### Features
* Method Setters: Get/Post/Put/Patch/Delete/Head
* Add or Set Request Headers
* Base/Path: Extend a Sling for different endpoints
* Encode structs into URL query parameters
* Encode a form or JSON into the Request Body
* Receive JSON success or failure responses
## Install
go get github.com/dghubble/sling
## Documentation
Read [GoDoc](https://godoc.org/github.com/dghubble/sling)
## Usage
Use a Sling to set path, method, header, query, or body properties and create an `http.Request`.
```go
type Params struct {
Count int `url:"count,omitempty"`
}
params := &Params{Count: 5}
req, err := sling.New().Get("https://example.com").QueryStruct(params).Request()
client.Do(req)
```
### Path
Use `Path` to set or extend the URL for created Requests. Extension means the path will be resolved relative to the existing URL.
```go
// creates a GET request to https://example.com/foo/bar
req, err := sling.New().Base("https://example.com/").Path("foo/").Path("bar").Request()
```
Use `Get`, `Post`, `Put`, `Patch`, `Delete`, or `Head` which are exactly the same as `Path` except they set the HTTP method too.
```go
req, err := sling.New().Post("http://upload.com/gophers")
```
### Headers
`Add` or `Set` headers for requests created by a Sling.
```go
s := sling.New().Base(baseUrl).Set("User-Agent", "Gophergram API Client")
req, err := s.New().Get("gophergram/list").Request()
```
### Query
#### QueryStruct
Define [url tagged structs](https://godoc.org/github.com/google/go-querystring/query). Use `QueryStruct` to encode a struct as query parameters on requests.
```go
// Github Issue Parameters
type IssueParams struct {
Filter string `url:"filter,omitempty"`
State string `url:"state,omitempty"`
Labels string `url:"labels,omitempty"`
Sort string `url:"sort,omitempty"`
Direction string `url:"direction,omitempty"`
Since string `url:"since,omitempty"`
}
```
```go
githubBase := sling.New().Base("https://api.github.com/").Client(httpClient)
path := fmt.Sprintf("repos/%s/%s/issues", owner, repo)
params := &IssueParams{Sort: "updated", State: "open"}
req, err := githubBase.New().Get(path).QueryStruct(params).Request()
```
### Body
#### JSON Body
Define [JSON tagged structs](https://golang.org/pkg/encoding/json/). Use `BodyJSON` to JSON encode a struct as the Body on requests.
```go
type IssueRequest struct {
Title string `json:"title,omitempty"`
Body string `json:"body,omitempty"`
Assignee string `json:"assignee,omitempty"`
Milestone int `json:"milestone,omitempty"`
Labels []string `json:"labels,omitempty"`
}
```
```go
githubBase := sling.New().Base("https://api.github.com/").Client(httpClient)
path := fmt.Sprintf("repos/%s/%s/issues", owner, repo)
body := &IssueRequest{
Title: "Test title",
Body: "Some issue",
}
req, err := githubBase.New().Post(path).BodyJSON(body).Request()
```
Requests will include an `application/json` Content-Type header.
#### Form Body
Define [url tagged structs](https://godoc.org/github.com/google/go-querystring/query). Use `BodyForm` to form url encode a struct as the Body on requests.
```go
type StatusUpdateParams struct {
Status string `url:"status,omitempty"`
InReplyToStatusId int64 `url:"in_reply_to_status_id,omitempty"`
MediaIds []int64 `url:"media_ids,omitempty,comma"`
}
```
```go
tweetParams := &StatusUpdateParams{Status: "writing some Go"}
req, err := twitterBase.New().Post(path).BodyForm(tweetParams).Request()
```
Requests will include an `application/x-www-form-urlencoded` Content-Type header.
#### Plain Body
Use `Body` to set a plain `io.Reader` on requests created by a Sling.
```go
body := strings.NewReader("raw body")
req, err := sling.New().Base("https://example.com").Body(body).Request()
```
Set a content type header, if desired (e.g. `Set("Content-Type", "text/plain")`).
### Extend a Sling
Each Sling creates a standard `http.Request` (e.g. with some path and query
params) each time `Request()` is called. You may wish to extend an existing Sling to minimize duplication (e.g. a common client or base url).
Each Sling instance provides a `New()` method which creates an independent copy, so setting properties on the child won't mutate the parent Sling.
```go
const twitterApi = "https://api.twitter.com/1.1/"
base := sling.New().Base(twitterApi).Client(authClient)
// statuses/show.json Sling
tweetShowSling := base.New().Get("statuses/show.json").QueryStruct(params)
req, err := tweetShowSling.Request()
// statuses/update.json Sling
tweetPostSling := base.New().Post("statuses/update.json").BodyForm(params)
req, err := tweetPostSling.Request()
```
Without the calls to `base.New()`, `tweetShowSling` and `tweetPostSling` would reference the base Sling and POST to
"https://api.twitter.com/1.1/statuses/show.json/statuses/update.json", which
is undesired.
Recap: If you wish to *extend* a Sling, create a new child copy with `New()`.
### Sending
#### Receive
Define a JSON struct to decode a type from 2XX success responses. Use `ReceiveSuccess(successV interface{})` to send a new Request and decode the response body into `successV` if it succeeds.
```go
// Github Issue (abbreviated)
type Issue struct {
Title string `json:"title"`
Body string `json:"body"`
}
```
```go
issues := new([]Issue)
resp, err := githubBase.New().Get(path).QueryStruct(params).ReceiveSuccess(issues)
fmt.Println(issues, resp, err)
```
Most APIs return failure responses with JSON error details. To decode these, define success and failure JSON structs. Use `Receive(successV, failureV interface{})` to send a new Request that will automatically decode the response into the `successV` for 2XX responses or into `failureV` for non-2XX responses.
```go
type GithubError struct {
Message string `json:"message"`
Errors []struct {
Resource string `json:"resource"`
Field string `json:"field"`
Code string `json:"code"`
} `json:"errors"`
DocumentationURL string `json:"documentation_url"`
}
```
```go
issues := new([]Issue)
githubError := new(GithubError)
resp, err := githubBase.New().Get(path).QueryStruct(params).Receive(issues, githubError)
fmt.Println(issues, githubError, resp, err)
```
Pass a nil `successV` or `failureV` argument to skip JSON decoding into that value.
### Modify a Request
Sling provides the raw http.Request so modifications can be made using standard net/http features. For example, in Go 1.7+ , add HTTP tracing to a request with a context:
```go
req, err := sling.New().Get("https://example.com").QueryStruct(params).Request()
// handle error
trace := &httptrace.ClientTrace{
DNSDone: func(dnsInfo httptrace.DNSDoneInfo) {
fmt.Printf("DNS Info: %+v\n", dnsInfo)
},
GotConn: func(connInfo httptrace.GotConnInfo) {
fmt.Printf("Got Conn: %+v\n", connInfo)
},
}
req = req.WithContext(httptrace.WithClientTrace(req.Context(), trace))
client.Do(req)
```
### Build an API
APIs typically define an endpoint (also called a service) for each type of resource. For example, here is a tiny Github IssueService which [lists](https://developer.github.com/v3/issues/#list-issues-for-a-repository) repository issues.
```go
const baseURL = "https://api.github.com/"
type IssueService struct {
sling *sling.Sling
}
func NewIssueService(httpClient *http.Client) *IssueService {
return &IssueService{
sling: sling.New().Client(httpClient).Base(baseURL),
}
}
func (s *IssueService) ListByRepo(owner, repo string, params *IssueListParams) ([]Issue, *http.Response, error) {
issues := new([]Issue)
githubError := new(GithubError)
path := fmt.Sprintf("repos/%s/%s/issues", owner, repo)
resp, err := s.sling.New().Get(path).QueryStruct(params).Receive(issues, githubError)
if err == nil {
err = githubError
}
return *issues, resp, err
}
```

Create a Pull Request to add a link to your own API.
## Motivation
Many client libraries follow the lead of [google/go-github](https://github.com/google/go-github) (our inspiration!), but do so by reimplementing logic common to all clients.
This project borrows and abstracts those ideas into a Sling, an agnostic component any API client can use for creating and sending requests.

Package sling is a Go HTTP client library for creating and sending API requests.
Slings store HTTP Request properties to simplify sending requests and decoding
responses. Check the examples to learn how to compose a Sling into your API
client.
Usage
Use a Sling to set path, method, header, query, or body properties and create an
http.Request.
type Params struct {
Count int `url:"count,omitempty"`
}
params := &Params{Count: 5}
req, err := sling.New().Get("https://example.com").QueryStruct(params).Request()
client.Do(req)
Path
Use Path to set or extend the URL for created Requests. Extension means the
path will be resolved relative to the existing URL.
// creates a GET request to https://example.com/foo/bar
req, err := sling.New().Base("https://example.com/").Path("foo/").Path("bar").Request()
Use Get, Post, Put, Patch, Delete, or Head which are exactly the same as Path
except they set the HTTP method too.
req, err := sling.New().Post("http://upload.com/gophers")
Headers
Add or Set headers for requests created by a Sling.
s := sling.New().Base(baseUrl).Set("User-Agent", "Gophergram API Client")
req, err := s.New().Get("gophergram/list").Request()
QueryStruct
Define url parameter structs (https://godoc.org/github.com/google/go-querystring/query).
Use QueryStruct to encode a struct as query parameters on requests.
// Github Issue Parameters
type IssueParams struct {
Filter string `url:"filter,omitempty"`
State string `url:"state,omitempty"`
Labels string `url:"labels,omitempty"`
Sort string `url:"sort,omitempty"`
Direction string `url:"direction,omitempty"`
Since string `url:"since,omitempty"`
}
githubBase := sling.New().Base("https://api.github.com/").Client(httpClient)
path := fmt.Sprintf("repos/%s/%s/issues", owner, repo)
params := &IssueParams{Sort: "updated", State: "open"}
req, err := githubBase.New().Get(path).QueryStruct(params).Request()
Json Body
Define JSON tagged structs (https://golang.org/pkg/encoding/json/).
Use BodyJSON to JSON encode a struct as the Body on requests.
type IssueRequest struct {
Title string `json:"title,omitempty"`
Body string `json:"body,omitempty"`
Assignee string `json:"assignee,omitempty"`
Milestone int `json:"milestone,omitempty"`
Labels []string `json:"labels,omitempty"`
}
githubBase := sling.New().Base("https://api.github.com/").Client(httpClient)
path := fmt.Sprintf("repos/%s/%s/issues", owner, repo)
body := &IssueRequest{
Title: "Test title",
Body: "Some issue",
}
req, err := githubBase.New().Post(path).BodyJSON(body).Request()
Requests will include an "application/json" Content-Type header.
Form Body
Define url tagged structs (https://godoc.org/github.com/google/go-querystring/query).
Use BodyForm to form url encode a struct as the Body on requests.
type StatusUpdateParams struct {

MediaIds []int64 `url:"media_ids,omitempty,comma"`
}
tweetParams := &StatusUpdateParams{Status: "writing some Go"}
req, err := twitterBase.New().Post(path).BodyForm(tweetParams).Request()
Requests will include an "application/x-www-form-urlencoded" Content-Type
header.
Plain Body
Use Body to set a plain io.Reader on requests created by a Sling.
body := strings.NewReader("raw body")
req, err := sling.New().Base("https://example.com").Body(body).Request()
Set a content type header, if desired (e.g. Set("Content-Type", "text/plain")).
Extend a Sling
Each Sling generates an http.Request (say with some path and query params)
each time Request() is called, based on its state. When creating
different slings, you may wish to extend an existing Sling to minimize
duplication (e.g. a common client).
Each Sling instance provides a New() method which creates an independent copy,
so setting properties on the child won't mutate the parent Sling.
const twitterApi = "https://api.twitter.com/1.1/"
base := sling.New().Base(twitterApi).Client(authClient)
// statuses/show.json Sling
tweetShowSling := base.New().Get("statuses/show.json").QueryStruct(params)
req, err := tweetShowSling.Request()
// statuses/update.json Sling
tweetPostSling := base.New().Post("statuses/update.json").BodyForm(params)
req, err := tweetPostSling.Request()
Without the calls to base.New(), tweetShowSling and tweetPostSling would
reference the base Sling and POST to
"https://api.twitter.com/1.1/statuses/show.json/statuses/update.json", which
is undesired.
Recap: If you wish to extend a Sling, create a new child copy with New().
Receive
Define a JSON struct to decode a type from 2XX success responses. Use
ReceiveSuccess(successV interface{}) to send a new Request and decode the
response body into successV if it succeeds.
// Github Issue (abbreviated)
type Issue struct {
Title string `json:"title"`
Body string `json:"body"`
}
issues := new([]Issue)
resp, err := githubBase.New().Get(path).QueryStruct(params).ReceiveSuccess(issues)
fmt.Println(issues, resp, err)
Most APIs return failure responses with JSON error details. To decode these,
define success and failure JSON structs. Use
Receive(successV, failureV interface{}) to send a new Request that will
automatically decode the response into the successV for 2XX responses or into
failureV for non-2XX responses.
type GithubError struct {
Message string `json:"message"`
Errors []struct {
Resource string `json:"resource"`
Field string `json:"field"`
Code string `json:"code"`
} `json:"errors"`
DocumentationURL string `json:"documentation_url"`
}
issues := new([]Issue)
githubError := new(GithubError)
resp, err := githubBase.New().Get(path).QueryStruct(params).Receive(issues, githubError)
fmt.Println(issues, githubError, resp, err)
Pass a nil successV or failureV argument to skip JSON decoding into that value.

# go-restful-swagger12
[![Build Status](https://travis-ci.org/emicklei/go-restful-swagger12.png)](https://travis-ci.org/emicklei/go-restful-swagger12)
[![GoDoc](https://godoc.org/github.com/emicklei/go-restful-swagger12?status.svg)](https://godoc.org/github.com/emicklei/go-restful-swagger12)
How to use Swagger UI with go-restful
=
Get the Swagger UI sources (version 1.2 only)
git clone https://github.com/wordnik/swagger-ui.git
The project contains a "dist" folder.
Its contents has all the Swagger UI files you need.
The `index.html` has an `url` set to `http://petstore.swagger.wordnik.com/api/api-docs`.
You need to change that to match your WebService JSON endpoint e.g. `http://localhost:8080/apidocs.json`
Now, you can install the Swagger WebService for serving the Swagger specification in JSON.
config := swagger.Config{
WebServices: restful.RegisteredWebServices(),
ApiPath: "/apidocs.json",
SwaggerPath: "/apidocs/",
SwaggerFilePath: "/Users/emicklei/Projects/swagger-ui/dist"}
swagger.InstallSwaggerService(config)
Documenting Structs
--
Currently there are 2 ways to document your structs in the go-restful Swagger.
###### By using struct tags
- Use tag "description" to annotate a struct field with a description to show in the UI
- Use tag "modelDescription" to annotate the struct itself with a description to show in the UI. The tag can be added in an field of the struct and in case that there are multiple definition, they will be appended with an empty line.
###### By using the SwaggerDoc method
Here is an example with an `Address` struct and the documentation for each of the fields. The `""` is a special entry for **documenting the struct itself**.
type Address struct {
Country string `json:"country,omitempty"`
PostCode int `json:"postcode,omitempty"`
}
func (Address) SwaggerDoc() map[string]string {
return map[string]string{
"": "Address doc",
"country": "Country doc",
"postcode": "PostCode doc",
}
}
This example will generate a JSON like this
{
"Address": {
"id": "Address",
"description": "Address doc",
"properties": {
"country": {
"type": "string",
"description": "Country doc"
},
"postcode": {
"type": "integer",
"format": "int32",
"description": "PostCode doc"
}
}
}
}
**Very Important Notes:**
- `SwaggerDoc()` is using a **NON-Pointer** receiver (e.g. func (Address) and not func (*Address))
- The returned map should use as key the name of the field as defined in the JSON parameter (e.g. `"postcode"` and not `"PostCode"`)
Notes
--
- The Nickname of an Operation is automatically set by finding the name of the function. You can override it using RouteBuilder.Operation(..)
- The WebServices field of swagger.Config can be used to control which service you want to expose and document ; you can have multiple configs and therefore multiple endpoints.

swagger "github.com/emicklei/go-restful-swagger12"
- moved swagger 1.2 code to go-restful-swagger12
- created TAG 2.0.0
2017-01-27
- remove defer request body close
- expose Dispatch for testing filters and Routefunctions
- swagger response model cannot be array
- created TAG 1.0.0
2016-12-22
- (API change) Remove code related to caching request content. Removes SetCacheReadEntity(doCache bool)
2016-11-26
- Default change! now use CurlyRouter (was RouterJSR311)
- Default change! no more caching of request content
- Default change! do not recover from panics
2016-09-22
- fix the DefaultRequestContentType feature
2016-02-14
- take the qualify factor of the Accept header mediatype into account when deciding the contentype of the response
- add constructors for custom entity accessors for xml and json
2015-09-27
- rename new WriteStatusAnd... to WriteHeaderAnd... for consistency
2015-09-25
- fixed problem with changing Header after WriteHeader (issue 235)
2015-09-14
- changed behavior of WriteHeader (immediate write) and WriteEntity (no status write)
- added support for custom EntityReaderWriters.
2015-08-06
- add support for reading entities from compressed request content
- use sync.Pool for compressors of http response and request body
- add Description to Parameter for documentation in Swagger UI
2015-03-20

2015-03-18
- if not specified, the Operation is derived from the Route function
2015-03-17
- expose Parameter creation functions
- make trace logger an interface
- fix OPTIONSFilter
- customize rendering of ServiceError
- JSR311 router now handles wildcards
- add Notes to Route
2014-11-27
- (api add) PrettyPrint per response. (as proposed in #167)
2014-11-12
- (api add) ApiVersion(.) for documentation in Swagger UI
2014-11-10
- (api change) struct fields tagged with "description" show up in Swagger UI
2014-10-31
- (api change) ReturnsError -> Returns
- (api add) RouteBuilder.Do(aBuilder) for DRY use of RouteBuilder
- fix swagger nested structs
- sort Swagger response messages by code
2014-10-23
- (api add) ReturnsError allows you to document Http codes in swagger
- fixed problem with greedy CurlyRouter
- (api add) Access-Control-Max-Age in CORS
- add tracing functionality (injectable) for debugging purposes
- support JSON parse 64bit int
- fix empty parameters for swagger
- WebServicesUrl is now optional for swagger
- fixed duplicate AccessControlAllowOrigin in CORS
- (api change) expose ServeMux in container
- (api add) added AllowedDomains in CORS
- (api add) ParameterNamed for detailed documentation
2014-04-16
- (api add) expose constructor of Request for testing.
2014-06-27
- (api add) ParameterNamed gives access to a Parameter definition and its data (for further specification).
- (api add) SetCacheReadEntity allow scontrol over whether or not the request body is being cached (default true for compatibility reasons).
2014-07-03
- (api add) CORS can be configured with a list of allowed domains
2014-03-12
- (api add) Route path parameters can use wildcard or regular expressions. (requires CurlyRouter)
2014-02-26
- (api add) Request now provides information about the matched Route, see method SelectedRoutePath
2014-02-17
- (api change) renamed parameter constants (go-lint checks)
2014-01-10
- (api add) support for CloseNotify, see http://golang.org/pkg/net/http/#CloseNotifier
2014-01-07
- (api change) Write* methods in Response now return the error or nil.
- added example of serving HTML from a Go template.
- fixed comparing Allowed headers in CORS (is now case-insensitive)
2013-11-13
- (api add) Response knows how many bytes are written to the response body.
2013-10-29
- (api add) RecoverHandler(handler RecoverHandleFunction) to change how panic recovery is handled. Default behavior is to log and return a stacktrace. This may be a security issue as it exposes sourcecode information.
2013-10-04
- (api add) Response knows what HTTP status has been written
- (api add) Request can have attributes (map of string->interface, also called request-scoped variables
2013-09-12
- (api change) Router interface simplified
- Implemented CurlyRouter, a Router that does not use|allow regular expressions in paths
2013-08-05
- add OPTIONS support
- add CORS support
2013-08-27
- fixed some reported issues (see github)
- (api change) deprecated use of WriteError; use WriteErrorString instead
2014-04-15
- (fix) v1.0.1 tag: fix Issue 111: WriteErrorString
2013-08-08
- (api add) Added implementation Container: a WebServices collection with its own http.ServeMux allowing multiple endpoints per program. Existing uses of go-restful will register their services to the DefaultContainer.
- (api add) the swagger package has be extended to have a UI per container.
- if panic is detected then a small stack trace is printed (thanks to runner-mei)
- (api add) WriteErrorString to Response
Important API changes:
- (api remove) package variable DoNotRecover no longer works ; use restful.DefaultContainer.DoNotRecover(true) instead.
- (api remove) package variable EnableContentEncoding no longer works ; use restful.DefaultContainer.EnableContentEncoding(true) instead.
2013-07-06
- (api add) Added support for response encoding (gzip and deflate(zlib)). This feature is disabled on default (for backwards compatibility). Use restful.EnableContentEncoding = true in your initialization to enable this feature.
2013-06-19
- (improve) DoNotRecover option, moved request body closer, improved ReadEntity
2013-06-03
- (api change) removed Dispatcher interface, hide PathExpression
- changed receiver names of type functions to be more idiomatic Go
2013-06-02
- (optimize) Cache the RegExp compilation of Paths.
2013-05-22
- (api add) Added support for request/response filter functions
2013-05-18
- (api add) Added feature to change the default Http Request Dispatch function (travis cline)
- (api change) Moved Swagger Webservice to swagger package (see example restful-user)

go-restful
==========
package for building REST-style Web Services using Google Go
[![Build Status](https://travis-ci.org/emicklei/go-restful.png)](https://travis-ci.org/emicklei/go-restful)
[![Go Report Card](https://goreportcard.com/badge/github.com/emicklei/go-restful)](https://goreportcard.com/report/github.com/emicklei/go-restful)
[![GoDoc](https://godoc.org/github.com/emicklei/go-restful?status.svg)](https://godoc.org/github.com/emicklei/go-restful)
- [Code examples](https://github.com/emicklei/go-restful/tree/master/examples)
REST asks developers to use HTTP methods explicitly and in a way that's consistent with the protocol definition. This basic REST design principle establishes a one-to-one mapping between create, read, update, and delete (CRUD) operations and HTTP methods. According to this mapping:
- GET = Retrieve a representation of a resource
- POST = Create if you are sending content to the server to create a subordinate of the specified resource collection, using some server-side algorithm.
- PUT = Create if you are sending the full content of the specified resource (URI).
- PUT = Update if you are updating the full content of the specified resource.
- DELETE = Delete if you are requesting the server to delete the resource
- PATCH = Update partial content of a resource
- OPTIONS = Get information about the communication options for the request URI
### Example
```Go
ws := new(restful.WebService)
ws.
Path("/users").
Consumes(restful.MIME_XML, restful.MIME_JSON).
Produces(restful.MIME_JSON, restful.MIME_XML)
ws.Route(ws.GET("/{user-id}").To(u.findUser).
Doc("get a user").
Param(ws.PathParameter("user-id", "identifier of the user").DataType("string")).
Writes(User{}))
...
func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
id := request.PathParameter("user-id")
...
}
```
[Full API of a UserResource](https://github.com/emicklei/go-restful/tree/master/examples/restful-user-resource.go)
### Features
- Routes for request &#8594; function mapping with path parameter (e.g. {id}) support
- Configurable router:
- (default) Fast routing algorithm that allows static elements, regular expressions and dynamic parameters in the URL path (e.g. /meetings/{id} or /static/{subpath:*}
- Routing algorithm after [JSR311](http://jsr311.java.net/nonav/releases/1.1/spec/spec.html) that is implemented using (but does **not** accept) regular expressions
- Request API for reading structs from JSON/XML and accesing parameters (path,query,header)
- Response API for writing structs to JSON/XML and setting headers
- Customizable encoding using EntityReaderWriter registration
- Filters for intercepting the request &#8594; response flow on Service or Route level
- Request-scoped variables using attributes
- Containers for WebServices on different HTTP endpoints
- Content encoding (gzip,deflate) of request and response payloads
- Automatic responses on OPTIONS (using a filter)
- Automatic CORS request handling (using a filter)
- API declaration for Swagger UI (see [go-restful-swagger12](https://github.com/emicklei/go-restful-swagger12),[go-restful-openapi](https://github.com/emicklei/go-restful-openapi))
- Panic recovery to produce HTTP 500, customizable using RecoverHandler(...)
- Route errors produce HTTP 404/405/406/415 errors, customizable using ServiceErrorHandler(...)
- Configurable (trace) logging
- Customizable gzip/deflate readers and writers using CompressorProvider registration
