GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

# Vikunja Web Handler
[![License: LGPL v3](https://img.shields.io/badge/License-LGPL%20v3-blue.svg)](LICENSE)
[![Go Report Card](https://goreportcard.com/badge/code.vikunja.io/web)](https://goreportcard.com/report/code.vikunja.io/web)
> When I started Vikunja, I started like everyone else, by writing a bunch of functions to do the logic and then a bunch of
handler functions to parse the request data and call the implemented functions to do the logic and eventually return a dataset.
After I implemented some functions, I've decided to save me a lot of hassle and put most of that "parse the request and call a
processing function"-logic to a general interface to facilitate development and not having to have a lot of similar code all over the place.
This webhandler was built to be used in a REST-API, it takes and returns JSON, but can also be used in combination with own other handler
implementations thus leading to much flexibility.
## Features
* Easy to use
* Built for REST-APIs
* Beautiful error handling built in
* Manages rights
* Pluggable authentication mechanisms
## Table of contents

* [Errors](#errors)
* [URL param binder](#how-the-url-param-binder-works)
## Installation
Using the web handler in your application is pretty straight forward, simply run `go get -u code.vikunja.io/web` and start using it.
In order to use the common web handler, the struct must implement the `web.CRUDable` and `web.Rights` interface.
## CRUDable
This interface defines methods to Create/Read/ReadAll/Update/Delete something. It is defined as followed:
```go
type CRUDable interface {
Create(Auth) error
ReadOne() error
ReadAll(string, Auth, int) (interface{}, error)
Update() error
Delete() error
}
```
Each of these methods is called on an instance of a struct like so:
```go
func (l *List) ReadOne() (err error) {
*l, err = GetListByID(l.ID)
return
}
```
In that case, it takes the `ID` saved in the struct instance, gets the full list object and fills the original object with it.
(See parambinder to understand where that `ID` is coming from).
All functions should behave like this, if they create or update something, they should return the created/updated struct
instance. The only exception is `ReadAll()` which returns an interface. Usually this is an array, because, well you cannot
make an array of a set type (If you know a way to do this, don't hesitate to drop me a message).
## Rights
This interface defines methods to check for rights on structs. They accept an `Auth`-element as parameter and return a `bool`.
The interface is defined as followed:
```go
type Rights interface {
IsAdmin(Auth) bool
CanWrite(Auth) bool
CanRead(Auth) bool
CanDelete(Auth) bool
CanUpdate(Auth) bool
CanCreate(Auth) bool
}
```
When using the standard web handler, all methods except `CanRead()` are called before their `CRUD` counterparts. `CanRead()`
is called after `ReadOne()` was invoked as this would otherwise mean getting an object from the db to check if the user has the
right to see it and then getting it again if thats the case. Calling the function afterwards means we only have to get the
object once.
## Handler Config
The handler has some options which you can (and need to) configure.
#### Auth
`Auth` is an interface with some methods to decouple the action of getting the current user from the web handler.
The function defined via `Auths` should return a struct which implements the `Auth` interface.
To define the thing which gets the appropriate auth object, you need to call a middleware like so (After all auth middlewares were called):
#### Logging
You can provide your own instance of `logger.Logger` (using [this package](https://github.com/op/go-logging)) to the handler.
It will use this instance to log errors which are not better specified or things like users trying to do something they're
not allowed to do and so on.
#### Full Example
```go
e.Use(func(next echo.HandlerFunc) echo.HandlerFunc {
return func(c echo.Context) error {
c.Set("AuthProvider", &web.Auths{
AuthObject: func(echo.Context) (web.Auth, error) {
return models.GetCurrentUser(c) // Your functions
},
})
c.Set("LoggingProvider", &log.Log)
return next(c)
}
})
```
## Preprocessing
### Pagination
When using the `ReadAll`-method, the third parameter contains the requested page. Your function should return only the number of results
corresponding to that page. The number of items per page is definied in the config as `service.pagecount` (Get it with `viper.GetInt("service.pagecount")`).
These can be calculated in combination with a helper function, `getLimitFromPageIndex(pageIndex)` which returns
SQL-needed `limit` (max-length) and `offset` parameters. You can feed this function directly into xorm's `Limit`-Function like so:
```go
lists := []List{}
err := x.Limit(getLimitFromPageIndex(pageIndex)).Find(&lists)
```
### Search
When using the `ReadAll`-method, the first parameter is a search term which should be used to search items of your struct. You define the critera.
Users can then pass the `?s=something` parameter to the url to search.
As the logic for "give me everything" and "give me everything where the name contains 'something'" is mostly the same, we made the decision to design
the function like this, in order to keep the places with mostly the same logic as few as possible. Also just adding `?s=query` to the url one already
knows and uses is a lot more convenient.
## Standard web handler
You can define routes for the standard web handler like so:
`models.List` needs to implement `web.CRUDable` and `web.Rights`.
```go
listHandler := &crud.WebHandler{
EmptyStruct: func() crud.CObject {
return &models.List{}
},
}
a.GET("/lists", listHandler.ReadAllWeb)
a.GET("/lists/:list", listHandler.ReadOneWeb)
a.POST("/lists/:list", listHandler.UpdateWeb)
a.DELETE("/lists/:list", listHandler.DeleteWeb)
a.PUT("/namespaces/:namespace/lists", listHandler.CreateWeb)
```
The handler will take care of everything like parsing the request, checking rights, pretty-print errors and return appropriate responses.
## Errors
Error types with their messages and http-codes should be implemented by you somewhere in your application and then returned by
the appropriate function when an error occures. If the error type implements `HTTPError`, the server returns a user-friendly
error message when this error occours. This means it returns a good HTTP status code, a message, and an error code. The error
code should be unique across all error codes and can be used on the client to show a localized error message or do other stuff
based on the exact error the server returns. That way the client won't have to "guess" that the error message remains the same
over multiple versions of your application.
An `HTTPError` is defined as follows:
```go
type HTTPError struct {
HTTPCode int `json:"-"` // Can be any valid HTTP status code, I'd reccomend to use the constants of the http package.
Code int `json:"code"` // Must be a uniqe int identifier for this specific error. I'd reccomend defining a constant for this.
Message string `json:"message"` // A user-readable message what went wrong.
}
```
## How the url param binder works
The binder binds all values inside the url to their respective fields in a struct. Those fields need to have a tag
"param" with the name of the url placeholder which must be the same as in routes.
Whenever one of the standard CRUD methods is invoked, this binder is called, which enables one handler method
to handle all kinds of different urls with different parameters.

# 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
* **2016-11-14 (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})$`.
