+# 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://secure.travis-ci.org/PuerkitoBio/purell.png)](http://travis-ci.org/PuerkitoBio/purell)
+
+## Install
+
+`go get github.com/PuerkitoBio/purell`
+
+## Changelog
+
+*    **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})$`.

+## About
+
+This directory contains a collection of scripts used to build and manage this
+repository. If there are any issues regarding the intention of a particular
+script (or even part of a certain script), please reach out to us.
+It may help us either refine our current scripts, or add on new ones
+that are appropriate for a given use case.
+
+## DinD (dind.sh)
+
+DinD is a wrapper script which allows Docker to be run inside a Docker
+container. DinD requires the container to
+be run with privileged mode enabled.
+
+## Generate Authors (generate-authors.sh)
+
+Generates AUTHORS; a file with all the names and corresponding emails of
+individual contributors. AUTHORS can be found in the home directory of
+this repository.
+
+## Make
+
+There are two make files, each with different extensions. Neither are supposed
+to be called directly; only invoke `make`. Both scripts run inside a Docker
+container.
+
+### make.ps1
+
+- The Windows native build script that uses PowerShell semantics; it is limited
+unlike `hack\make.sh` since it does not provide support for the full set of
+operations provided by the Linux counterpart, `make.sh`. However, `make.ps1`
+does provide support for local Windows development and Windows to Windows CI.
+More information is found within `make.ps1` by the author, @jhowardmsft
+
+### make.sh
+
+- Referenced via `make test` when running tests on a local machine,
+or directly referenced when running tests inside a Docker development container.  
+- When running on a local machine, `make test` to run all tests found in
+`test`, `test-unit`, `test-integration`, and `test-docker-py` on
+your local machine. The default timeout is set in `make.sh` to 60 minutes
+(`${TIMEOUT:=60m}`), since it currently takes up to an hour to run
+all of the tests.
+- When running inside a Docker development container, `hack/make.sh` does
+not have a single target that runs all the tests. You need to provide a
+single command line with multiple targets that performs the same thing.
+An example referenced from [Run targets inside a development container](https://docs.docker.com/opensource/project/test-and-docs/#run-targets-inside-a-development-container): `root@5f8630b873fe:/go/src/github.com/moby/moby# hack/make.sh dynbinary binary cross test-unit test-integration test-docker-py`
+- For more information related to testing outside the scope of this README,
+refer to
+[Run tests and test documentation](https://docs.docker.com/opensource/project/test-and-docs/)
+
+## Release (release.sh)
+
+Releases any bundles built by `make` on a public AWS S3 bucket.
+For information regarding configuration, please view `release.sh`.
+
+## Vendor (vendor.sh)
+
+A shell script that is a wrapper around Vndr. For information on how to use
+this, please refer to [vndr's README](https://github.com/LK4D4/vndr/blob/master/README.md)

+# Integration Testing on Swarm
+
+IT on Swarm allows you to execute integration test in parallel across a Docker Swarm cluster
+
+## Architecture
+
+### Master service
+
+  - Works as a funker caller
+  - Calls a worker funker (`-worker-service`) with a chunk of `-check.f` filter strings (passed as a file via `-input` flag, typically `/mnt/input`)
+
+### Worker service
+
+  - Works as a funker callee
+  - Executes an equivalent of `TESTFLAGS=-check.f TestFoo|TestBar|TestBaz ... make test-integration-cli` using the bind-mounted API socket (`docker.sock`)
+
+### Client
+
+  - Controls master and workers via `docker stack`
+  - No need to have a local daemon
+
+Typically, the master and workers are supposed to be running on a cloud environment,
+while the client is supposed to be running on a laptop, e.g. Docker for Mac/Windows.
+
+## Requirement
+
+  - Docker daemon 1.13 or later
+  - Private registry for distributed execution with multiple nodes
+
+## Usage
+
+### Step 1: Prepare images
+
+    $ make build-integration-cli-on-swarm
+
+Following environment variables are known to work in this step:
+
+ - `BUILDFLAGS`
+ - `DOCKER_INCREMENTAL_BINARY`
+
+Note: during the transition into Moby Project, you might need to create a symbolic link `$GOPATH/src/github.com/docker/docker` to `$GOPATH/src/github.com/moby/moby`. 
+
+### Step 2: Execute tests
+
+    $ ./hack/integration-cli-on-swarm/integration-cli-on-swarm -replicas 40 -push-worker-image YOUR_REGISTRY.EXAMPLE.COM/integration-cli-worker:latest 
+
+Following environment variables are known to work in this step:
+
+ - `DOCKER_GRAPHDRIVER`
+ - `DOCKER_EXPERIMENTAL`
+
+#### Flags
+
+Basic flags:
+
+ - `-replicas N`: the number of worker service replicas. i.e. degree of parallelism.
+ - `-chunks N`: the number of chunks. By default, `chunks` == `replicas`.
+ - `-push-worker-image REGISTRY/IMAGE:TAG`: push the worker image to the registry. Note that if you have only single node and hence you do not need a private registry, you do not need to specify `-push-worker-image`.
+
+Experimental flags for mitigating makespan nonuniformity:
+
+ - `-shuffle`: Shuffle the test filter strings
+
+Flags for debugging IT on Swarm itself:
+
+ - `-rand-seed N`: the random seed. This flag is useful for deterministic replaying. By default(0), the timestamp is used.
+ - `-filters-file FILE`: the file contains `-check.f` strings. By default, the file is automatically generated.
+ - `-dry-run`: skip the actual workload
+ - `keep-executor`: do not auto-remove executor containers, which is used for running privileged programs on Swarm

+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.
