# Purell
Purell is a tiny Go library to normalize URLs. It returns a pure URL. Pure-ell. Sanitizer and all. Yeah, I know...
Based on the [wikipedia paper][wiki] and the [RFC 3986 document][rfc].
[![build status](https://travis-ci.org/PuerkitoBio/purell.svg?branch=master)](http://travis-ci.org/PuerkitoBio/purell)
## Install
`go get github.com/PuerkitoBio/purell`
## Changelog
* **v1.1.1** : Fix failing test due to Go1.12 changes (thanks to @ianlancetaylor).
* **2016-11-14 (v1.1.0)** : IDN: Conform to RFC 5895: Fold character width (thanks to @beeker1121).
* **2016-07-27 (v1.0.0)** : Normalize IDN to ASCII (thanks to @zenovich).
* **2015-02-08** : Add fix for relative paths issue ([PR #5][pr5]) and add fix for unnecessary encoding of reserved characters ([see issue #7][iss7]).
* **v0.2.0** : Add benchmarks, Attempt IDN support.
* **v0.1.0** : Initial release.
## Examples
From `example_test.go` (note that in your code, you would import "github.com/PuerkitoBio/purell", and would prefix references to its methods and constants with "purell."):
```go
package purell
import (
"fmt"
"net/url"
)
func ExampleNormalizeURLString() {
if normalized, err := NormalizeURLString("hTTp://someWEBsite.com:80/Amazing%3f/url/",
FlagLowercaseScheme|FlagLowercaseHost|FlagUppercaseEscapes); err != nil {
panic(err)
} else {
fmt.Print(normalized)
}
// Output: http://somewebsite.com:80/Amazing%3F/url/
}
func ExampleMustNormalizeURLString() {
normalized := MustNormalizeURLString("hTTpS://someWEBsite.com:443/Amazing%fa/url/",
FlagsUnsafeGreedy)
fmt.Print(normalized)
// Output: http://somewebsite.com/Amazing%FA/url
}
func ExampleNormalizeURL() {
if u, err := url.Parse("Http://SomeUrl.com:8080/a/b/.././c///g?c=3&a=1&b=9&c=0#target"); err != nil {
panic(err)
} else {
normalized := NormalizeURL(u, FlagsUsuallySafeGreedy|FlagRemoveDuplicateSlashes|FlagRemoveFragment)
fmt.Print(normalized)
}
// Output: http://someurl.com:8080/a/c/g?c=3&a=1&b=9&c=0
}
```
## API
As seen in the examples above, purell offers three methods, `NormalizeURLString(string, NormalizationFlags) (string, error)`, `MustNormalizeURLString(string, NormalizationFlags) (string)` and `NormalizeURL(*url.URL, NormalizationFlags) (string)`. They all normalize the provided URL based on the specified flags. Here are the available flags:
```go
const (
// Safe normalizations
FlagLowercaseScheme NormalizationFlags = 1 << iota // HTTP://host -> http://host, applied by default in Go1.1
FlagLowercaseHost // http://HOST -> http://host
FlagUppercaseEscapes // http://host/t%ef -> http://host/t%EF
FlagDecodeUnnecessaryEscapes // http://host/t%41 -> http://host/tA
FlagEncodeNecessaryEscapes // http://host/!"#$ -> http://host/%21%22#$
FlagRemoveDefaultPort // http://host:80 -> http://host
FlagRemoveEmptyQuerySeparator // http://host/path? -> http://host/path
// Usually safe normalizations
FlagRemoveTrailingSlash // http://host/path/ -> http://host/path
FlagAddTrailingSlash // http://host/path -> http://host/path/ (should choose only one of these add/remove trailing slash flags)
FlagRemoveDotSegments // http://host/path/./a/b/../c -> http://host/path/a/c
// Unsafe normalizations
FlagRemoveDirectoryIndex // http://host/path/index.html -> http://host/path/
FlagRemoveFragment // http://host/path#fragment -> http://host/path
FlagForceHTTP // https://host -> http://host
FlagRemoveDuplicateSlashes // http://host/path//a///b -> http://host/path/a/b
FlagRemoveWWW // http://www.host/ -> http://host/
FlagAddWWW // http://host/ -> http://www.host/ (should choose only one of these add/remove WWW flags)
FlagSortQuery // http://host/path?c=3&b=2&a=1&b=1 -> http://host/path?a=1&b=1&b=2&c=3
// Normalizations not in the wikipedia article, required to cover tests cases
// submitted by jehiah
FlagDecodeDWORDHost // http://1113982867 -> http://66.102.7.147
FlagDecodeOctalHost // http://0102.0146.07.0223 -> http://66.102.7.147
FlagDecodeHexHost // http://0x42660793 -> http://66.102.7.147
FlagRemoveUnnecessaryHostDots // http://.host../path -> http://host/path
FlagRemoveEmptyPortSeparator // http://host:/path -> http://host/path
// Convenience set of safe normalizations
FlagsSafe NormalizationFlags = FlagLowercaseHost | FlagLowercaseScheme | FlagUppercaseEscapes | FlagDecodeUnnecessaryEscapes | FlagEncodeNecessaryEscapes | FlagRemoveDefaultPort | FlagRemoveEmptyQuerySeparator
// For convenience sets, "greedy" uses the "remove trailing slash" and "remove www. prefix" flags,
// while "non-greedy" uses the "add (or keep) the trailing slash" and "add www. prefix".
// Convenience set of usually safe normalizations (includes FlagsSafe)
FlagsUsuallySafeGreedy NormalizationFlags = FlagsSafe | FlagRemoveTrailingSlash | FlagRemoveDotSegments
FlagsUsuallySafeNonGreedy NormalizationFlags = FlagsSafe | FlagAddTrailingSlash | FlagRemoveDotSegments
// Convenience set of unsafe normalizations (includes FlagsUsuallySafe)
FlagsUnsafeGreedy NormalizationFlags = FlagsUsuallySafeGreedy | FlagRemoveDirectoryIndex | FlagRemoveFragment | FlagForceHTTP | FlagRemoveDuplicateSlashes | FlagRemoveWWW | FlagSortQuery
FlagsUnsafeNonGreedy NormalizationFlags = FlagsUsuallySafeNonGreedy | FlagRemoveDirectoryIndex | FlagRemoveFragment | FlagForceHTTP | FlagRemoveDuplicateSlashes | FlagAddWWW | FlagSortQuery
// Convenience set of all available flags
FlagsAllGreedy = FlagsUnsafeGreedy | FlagDecodeDWORDHost | FlagDecodeOctalHost | FlagDecodeHexHost | FlagRemoveUnnecessaryHostDots | FlagRemoveEmptyPortSeparator
FlagsAllNonGreedy = FlagsUnsafeNonGreedy | FlagDecodeDWORDHost | FlagDecodeOctalHost | FlagDecodeHexHost | FlagRemoveUnnecessaryHostDots | FlagRemoveEmptyPortSeparator
)
```
For convenience, the set of flags `FlagsSafe`, `FlagsUsuallySafe[Greedy|NonGreedy]`, `FlagsUnsafe[Greedy|NonGreedy]` and `FlagsAll[Greedy|NonGreedy]` are provided for the similarly grouped normalizations on [wikipedia's URL normalization page][wiki]. You can add (using the bitwise OR `|` operator) or remove (using the bitwise AND NOT `&^` operator) individual flags from the sets if required, to build your own custom set.
The [full godoc reference is available on gopkgdoc][godoc].
Some things to note:
* `FlagDecodeUnnecessaryEscapes`, `FlagEncodeNecessaryEscapes`, `FlagUppercaseEscapes` and `FlagRemoveEmptyQuerySeparator` are always implicitly set, because internally, the URL string is parsed as an URL object, which automatically decodes unnecessary escapes, uppercases and encodes necessary ones, and removes empty query separators (an unnecessary `?` at the end of the url). So this operation cannot **not** be done. For this reason, `FlagRemoveEmptyQuerySeparator` (as well as the other three) has been included in the `FlagsSafe` convenience set, instead of `FlagsUnsafe`, where Wikipedia puts it.
* The `FlagDecodeUnnecessaryEscapes` decodes the following escapes (*from -> to*):
- %24 -> $
- %26 -> &
- %2B-%3B -> +,-./0123456789:;
- %3D -> =
- %40-%5A -> @ABCDEFGHIJKLMNOPQRSTUVWXYZ
- %5F -> _
- %61-%7A -> abcdefghijklmnopqrstuvwxyz
- %7E -> ~
* When the `NormalizeURL` function is used (passing an URL object), this source URL object is modified (that is, after the call, the URL object will be modified to reflect the normalization).
* The *replace IP with domain name* normalization (`http://208.77.188.166/ → http://www.example.com/`) is obviously not possible for a library without making some network requests. This is not implemented in purell.
* The *remove unused query string parameters* and *remove default query parameters* are also not implemented, since this is a very case-specific normalization, and it is quite trivial to do with an URL object.
### Safe vs Usually Safe vs Unsafe
Purell allows you to control the level of risk you take while normalizing an URL. You can aggressively normalize, play it totally safe, or anything in between.
Consider the following URL:
`HTTPS://www.RooT.com/toto/t%45%1f///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
Normalizing with the `FlagsSafe` gives:
`https://www.root.com/toto/tE%1F///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
With the `FlagsUsuallySafeGreedy`:
`https://www.root.com/toto/tE%1F///a/c?z=3&w=2&a=4&w=1#invalid`
And with `FlagsUnsafeGreedy`:
`http://root.com/toto/tE%1F/a/c?a=4&w=1&w=2&z=3`
## TODOs
* Add a class/default instance to allow specifying custom directory index names? At the moment, removing directory index removes `(^|/)((?:default|index)\.\w{1,4})$`.

# bitset
*Go language library to map between non-negative integers and boolean values*
[![Test](https://github.com/bits-and-blooms/bitset/workflows/Test/badge.svg)](https://github.com/willf/bitset/actions?query=workflow%3ATest)
[![Go Report Card](https://goreportcard.com/badge/github.com/willf/bitset)](https://goreportcard.com/report/github.com/willf/bitset)
[![PkgGoDev](https://pkg.go.dev/badge/github.com/bits-and-blooms/bitset?tab=doc)](https://pkg.go.dev/github.com/bits-and-blooms/bitset?tab=doc)
## Description
Package bitset implements bitsets, a mapping between non-negative integers and boolean values.
It should be more efficient than map[uint] bool.
It provides methods for setting, clearing, flipping, and testing individual integers.
But it also provides set intersection, union, difference, complement, and symmetric operations, as well as tests to check whether any, all, or no bits are set, and querying a bitset's current length and number of positive bits.
BitSets are expanded to the size of the largest set bit; the memory allocation is approximately Max bits, where Max is the largest set bit. BitSets are never shrunk. On creation, a hint can be given for the number of bits that will be used.
Many of the methods, including Set, Clear, and Flip, return a BitSet pointer, which allows for chaining.
### Example use:
```go
package main
import (
"fmt"
"math/rand"
"github.com/bits-and-blooms/bitset"
)
func main() {
fmt.Printf("Hello from BitSet!\n")
var b bitset.BitSet
// play some Go Fish
for i := 0; i < 100; i++ {
card1 := uint(rand.Intn(52))
card2 := uint(rand.Intn(52))
b.Set(card1)
if b.Test(card2) {
fmt.Println("Go Fish!")
}
b.Clear(card1)
}
// Chaining
b.Set(10).Set(11)
for i, e := b.NextSet(0); e; i, e = b.NextSet(i + 1) {
fmt.Println("The following bit is set:", i)
}
if b.Intersection(bitset.New(100).Set(10)).Count() == 1 {
fmt.Println("Intersection works.")
} else {
fmt.Println("Intersection doesn't work???")
}
}
```
As an alternative to BitSets, one should check out the 'big' package, which provides a (less set-theoretical) view of bitsets.
Package documentation is at: https://pkg.go.dev/github.com/bits-and-blooms/bitset?tab=doc
## Memory Usage
The memory usage of a bitset using N bits is at least N/8 bytes. The number of bits in a bitset is at least as large as one plus the greatest bit index you have accessed. Thus it is possible to run out of memory while using a bitset. If you have lots of bits, you might prefer compressed bitsets, like the [Roaring bitmaps](http://roaringbitmap.org) and its [Go implementation](https://github.com/RoaringBitmap/roaring).
## Implementation Note
Go 1.9 introduced a native `math/bits` library. We provide backward compatibility to Go 1.7, which might be removed.
It is possible that a later version will match the `math/bits` return signature for counts (which is `int`, rather than our library's `unit64`). If so, the version will be bumped.
## Installation
```bash
go get github.com/bits-and-blooms/bitset
```

semver for golang [![Build Status](https://travis-ci.org/blang/semver.svg?branch=master)](https://travis-ci.org/blang/semver) [![GoDoc](https://godoc.org/github.com/blang/semver?status.png)](https://godoc.org/github.com/blang/semver) [![Coverage Status](https://img.shields.io/coveralls/blang/semver.svg)](https://coveralls.io/r/blang/semver?branch=master)
======
semver is a [Semantic Versioning](http://semver.org/) library written in golang. It fully covers spec version `2.0.0`.
Usage
-----
```bash
$ go get github.com/blang/semver
```
Note: Always vendor your dependencies or fix on a specific version tag.
```go
import github.com/blang/semver
v1, err := semver.Make("1.0.0-beta")
v2, err := semver.Make("2.0.0-beta")
v1.Compare(v2)
```
Also check the [GoDocs](http://godoc.org/github.com/blang/semver).
Why should I use this lib?
-----
- Fully spec compatible
- No reflection
- No regex
- Fully tested (Coverage >99%)
- Readable parsing/validation errors
- Fast (See [Benchmarks](#benchmarks))
- Only Stdlib
- Uses values instead of pointers
- Many features, see below
Features
-----
- Parsing and validation at all levels
- Comparator-like comparisons
- Compare Helper Methods
- InPlace manipulation
- Ranges `>=1.0.0 <2.0.0 || >=3.0.0 !3.0.1-beta.1`
- Wildcards `>=1.x`, `<=2.5.x`
- Sortable (implements sort.Interface)
- database/sql compatible (sql.Scanner/Valuer)
- encoding/json compatible (json.Marshaler/Unmarshaler)
Ranges
------
A `Range` is a set of conditions which specify which versions satisfy the range.
A condition is composed of an operator and a version. The supported operators are:
- `<1.0.0` Less than `1.0.0`
- `<=1.0.0` Less than or equal to `1.0.0`
- `>1.0.0` Greater than `1.0.0`
- `>=1.0.0` Greater than or equal to `1.0.0`
- `1.0.0`, `=1.0.0`, `==1.0.0` Equal to `1.0.0`
- `!1.0.0`, `!=1.0.0` Not equal to `1.0.0`. Excludes version `1.0.0`.
Note that spaces between the operator and the version will be gracefully tolerated.
A `Range` can link multiple `Ranges` separated by space:
Ranges can be linked by logical AND:
- `>1.0.0 <2.0.0` would match between both ranges, so `1.1.1` and `1.8.7` but not `1.0.0` or `2.0.0`
- `>1.0.0 <3.0.0 !2.0.3-beta.2` would match every version between `1.0.0` and `3.0.0` except `2.0.3-beta.2`
Ranges can also be linked by logical OR:
- `<2.0.0 || >=3.0.0` would match `1.x.x` and `3.x.x` but not `2.x.x`
AND has a higher precedence than OR. It's not possible to use brackets.
Ranges can be combined by both AND and OR
- `>1.0.0 <2.0.0 || >3.0.0 !4.2.1` would match `1.2.3`, `1.9.9`, `3.1.1`, but not `4.2.1`, `2.1.1`
Range usage:
```
v, err := semver.Parse("1.2.3")
range, err := semver.ParseRange(">1.0.0 <2.0.0 || >=3.0.0")
if range(v) {
//valid
}
```
Example
-----
Have a look at full examples in [examples/main.go](examples/main.go)
```go
import github.com/blang/semver
v, err := semver.Make("0.0.1-alpha.preview+123.github")
fmt.Printf("Major: %d\n", v.Major)
fmt.Printf("Minor: %d\n", v.Minor)
fmt.Printf("Patch: %d\n", v.Patch)
fmt.Printf("Pre: %s\n", v.Pre)
fmt.Printf("Build: %s\n", v.Build)
// Prerelease versions array
if len(v.Pre) > 0 {
fmt.Println("Prerelease versions:")
for i, pre := range v.Pre {
fmt.Printf("%d: %q\n", i, pre)
}
}
// Build meta data array

Motivation
-----
I simply couldn't find any lib supporting the full spec. Others were just wrong or used reflection and regex which i don't like.
Contribution
-----

## `filepath-securejoin` ##
[![Build Status](https://travis-ci.org/cyphar/filepath-securejoin.svg?branch=master)](https://travis-ci.org/cyphar/filepath-securejoin)
An implementation of `SecureJoin`, a [candidate for inclusion in the Go
standard library][go#20126]. The purpose of this function is to be a "secure"
alternative to `filepath.Join`, and in particular it provides certain
guarantees that are not provided by `filepath.Join`.
This is the function prototype:
```go
func SecureJoin(root, unsafePath string) (string, error)
```
This library **guarantees** the following:
* If no error is set, the resulting string **must** be a child path of
`SecureJoin` and will not contain any symlink path components (they will all
be expanded).
* When expanding symlinks, all symlink path components **must** be resolved
relative to the provided root. In particular, this can be considered a
userspace implementation of how `chroot(2)` operates on file paths. Note that
these symlinks will **not** be expanded lexically (`filepath.Clean` is not
called on the input before processing).
* Non-existant path components are unaffected by `SecureJoin` (similar to
`filepath.EvalSymlinks`'s semantics).
* The returned path will always be `filepath.Clean`ed and thus not contain any
`..` components.
A (trivial) implementation of this function on GNU/Linux systems could be done
with the following (note that this requires root privileges and is far more
opaque than the implementation in this library, and also requires that
`readlink` is inside the `root` path):
```go
package securejoin
import (
"os/exec"
"path/filepath"
)
func SecureJoin(root, unsafePath string) (string, error) {
unsafePath = string(filepath.Separator) + unsafePath
cmd := exec.Command("chroot", root,
"readlink", "--canonicalize-missing", "--no-newline", unsafePath)
output, err := cmd.CombinedOutput()
if err != nil {
return "", err
}
expanded := string(output)
return filepath.Join(root, expanded), nil
}
```

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 ([go-restful-openapi](https://github.com/emicklei/go-restful-openapi), see [go-restful-swagger12](https://github.com/emicklei/go-restful-swagger12))
- 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
## How to customize
There are several hooks to customize the behavior of the go-restful package.
- Router algorithm
- Panic recovery
- JSON decoder
- Trace logging
- Compression
- Encoders for other serializers
- Use [jsoniter](https://github.com/json-iterator/go) by build this package using a tag, e.g. `go build -tags=jsoniter .`
TODO: write examples of these.

/*
Package restful , a lean package for creating REST-style WebServices without magic.
WebServices and Routes
A WebService has a collection of Route objects that dispatch incoming Http Requests to a function calls.
Typically, a WebService has a root path (e.g. /users) and defines common MIME types for its routes.
WebServices must be added to a container (see below) in order to handler Http requests from a server.
A Route is defined by a HTTP method, an URL path and (optionally) the MIME types it consumes (Content-Type) and produces (Accept).
This package has the logic to find the best matching Route and if found, call its Function.
ws := new(restful.WebService)
ws.
Path("/users").
Consumes(restful.MIME_JSON, restful.MIME_XML).
Produces(restful.MIME_JSON, restful.MIME_XML)
ws.Route(ws.GET("/{user-id}").To(u.findUser)) // u is a UserResource
...
// GET http://localhost:8080/users/1
func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
id := request.PathParameter("user-id")
...
}
The (*Request, *Response) arguments provide functions for reading information from the request and writing information back to the response.
See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-user-resource.go with a full implementation.
Regular expression matching Routes
A Route parameter can be specified using the format "uri/{var[:regexp]}" or the special version "uri/{var:*}" for matching the tail of the path.
For example, /persons/{name:[A-Z][A-Z]} can be used to restrict values for the parameter "name" to only contain capital alphabetic characters.
Regular expressions must use the standard Go syntax as described in the regexp package. (https://code.google.com/p/re2/wiki/Syntax)
This feature requires the use of a CurlyRouter.
Containers
A Container holds a collection of WebServices, Filters and a http.ServeMux for multiplexing http requests.
Using the statements "restful.Add(...) and restful.Filter(...)" will register WebServices and Filters to the Default Container.
The Default container of go-restful uses the http.DefaultServeMux.
You can create your own Container and create a new http.Server for that particular container.
container := restful.NewContainer()
server := &http.Server{Addr: ":8081", Handler: container}
Filters
A filter dynamically intercepts requests and responses to transform or use the information contained in the requests or responses.
You can use filters to perform generic logging, measurement, authentication, redirect, set response headers etc.
In the restful package there are three hooks into the request,response flow where filters can be added.
Each filter must define a FilterFunction:
func (req *restful.Request, resp *restful.Response, chain *restful.FilterChain)
Use the following statement to pass the request,response pair to the next filter or RouteFunction
chain.ProcessFilter(req, resp)
Container Filters
These are processed before any registered WebService.
// install a (global) filter for the default container (processed before any webservice)
restful.Filter(globalLogging)
WebService Filters
These are processed before any Route of a WebService.
// install a webservice filter (processed before any route)
ws.Filter(webserviceLogging).Filter(measureTime)
Route Filters
These are processed before calling the function associated with the Route.
// install 2 chained route filters (processed before calling findUser)
ws.Route(ws.GET("/{user-id}").Filter(routeLogging).Filter(NewCountFilter().routeCounter).To(findUser))
See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-filters.go with full implementations.
Response Encoding
Two encodings are supported: gzip and deflate. To enable this for all responses:
restful.DefaultContainer.EnableContentEncoding(true)
If a Http request includes the Accept-Encoding header then the response content will be compressed using the specified encoding.
Alternatively, you can create a Filter that performs the encoding and install it per WebService or Route.
See the example https://github.com/emicklei/go-restful/blob/master/examples/restful-encoding-filter.go
OPTIONS support
By installing a pre-defined container filter, your Webservice(s) can respond to the OPTIONS Http request.
Filter(OPTIONSFilter())
CORS
By installing the filter of a CrossOriginResourceSharing (CORS), your WebService(s) can handle CORS requests.
cors := CrossOriginResourceSharing{ExposeHeaders: []string{"X-My-Header"}, CookiesAllowed: false, Container: DefaultContainer}
Filter(cors.Filter)
Error Handling
Unexpected things happen. If a request cannot be processed because of a failure, your service needs to tell via the response what happened and why.
For this reason HTTP status codes exist and it is important to use the correct code in every exceptional situation.
400: Bad Request
If path or query parameters are not valid (content or type) then use http.StatusBadRequest.
404: Not Found
Despite a valid URI, the resource requested may not be available
500: Internal Server Error
If the application logic could not process the request (or write the response) then use http.StatusInternalServerError.
405: Method Not Allowed
The request has a valid URL but the method (GET,PUT,POST,...) is not allowed.
406: Not Acceptable
The request does not have or has an unknown Accept Header set for this operation.
415: Unsupported Media Type
The request does not have or has an unknown Content-Type Header set for this operation.
ServiceError
In addition to setting the correct (error) Http status code, you can choose to write a ServiceError message on the response.
Performance options
This package has several options that affect the performance of your service. It is important to understand them and how you can change it.
restful.DefaultContainer.DoNotRecover(false)
DoNotRecover controls whether panics will be caught to return HTTP 500.
If set to false, the container will recover from panics.
Default value is true
restful.SetCompressorProvider(NewBoundedCachedCompressors(20, 20))
If content encoding is enabled then the default strategy for getting new gzip/zlib writers and readers is to use a sync.Pool.
Because writers are expensive structures, performance is even more improved when using a preloaded cache. You can also inject your own implementation.
Trouble shooting
This package has the means to produce detail logging of the complete Http request matching process and filter invocation.
Enabling this feature requires you to set an implementation of restful.StdLogger (e.g. log.Logger) instance such as:
restful.TraceLogger(log.New(os.Stdout, "[restful] ", log.LstdFlags|log.Lshortfile))
Logging
The restful.SetLogger() method allows you to override the logger used by the package. By default restful
uses the standard library `log` package and logs to stdout. Different logging packages are supported as
long as they conform to `StdLogger` interface defined in the `log` sub-package, writing an adapter for your
preferred package is simple.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,

the copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent
to the Licensor or its representatives, including but not limited to
communication on electronic mailing lists, source code control systems,
and issue tracking systems that are managed by, or on behalf of, the
Licensor for the purpose of discussing and improving the Work, but
excluding communication that is conspicuously marked or otherwise
designated in writing by the copyright owner as "Not a Contribution."
"Contributor" shall mean Licensor and any individual or Legal Entity
on behalf of whom a Contribution has been received by Licensor and
subsequently incorporated within the Work.
2. Grant of Copyright License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.

agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at ivan+abuse@flanders.co.nz. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at [http://contributor-covenant.org/version/1/4][version]
