Note that the following handler would also be +accessible with that token: +```go +router.Handle("/protected", gate.Protect(yourHandler)) +``` + +To clarify, both clients and tokens have access to handlers that aren't protected with extra permissions, and +essentially, tokens are registered as clients with no extra permissions in the background. + +Creating a token like so: +```go +authorizationService := g8.NewAuthorizationService().WithToken("mytoken") +``` +is the equivalent of creating the following client: +```go +authorizationService := g8.NewAuthorizationService().WithClient(g8.NewClient("mytoken")) +``` + + +### With client provider +A client provider's task is to retrieve a Client from an external source (e.g. a database) when provided with a token. +You should use a client provider when you have a lot of tokens and it wouldn't make sense to register all of them using +`AuthorizationService`'s `WithToken`/`WithTokens`/`WithClient`/`WithClients`. + +Note that the provider is used as a fallback source. As such, if a token is explicitly registered using one of the 4 +aforementioned functions, the client provider will not be used. + +```go +clientProvider := g8.NewClientProvider(func(token string) *g8.Client { + // We'll assume that the following function calls your database and returns a struct "User" that + // has the user's token as well as the permissions granted to said user + user := database.GetUserByToken(token) + if user != nil { + return g8.NewClient(user.Token).WithPermissions(user.Permissions) + } + return nil +}) +authorizationService := g8.NewAuthorizationService().WithClientProvider(clientProvider) +gate := g8.New().WithAuthorizationService(authorizationService) +``` + +You can also configure the client provider to cache the output of the function you provide to retrieve clients by token: +```go +clientProvider := g8.NewClientProvider(...).WithCache(ttl, maxSize) +``` + +Since g8 leverages [TwiN/gocache](https://github.com/TwiN/gocache), you can also use gocache's +constants for configuring the TTL and the maximum size: +- Setting the TTL to `gocache.NoExpiration` (-1) will disable the TTL. +- Setting the maximum size to `gocache.NoMaxSize` (0) will disable the maximum cache size + +If you're using a TTL and have a lot of tokens (100k+), you may want to use `clientProvider.StartJanitor()` to allow +the cache to passively delete expired entries. If you have to re-initialize the client provider after the janitor has +been started, make sure to stop the janitor first (`clientProvider.StopJanitor()`). This is because the janitor runs on +a separate goroutine, thus, if you were to re-create a client provider and re-assign it, the old client provider would +still exist in memory with the old cache. I'm only specifying this for completeness, because for the overwhelming +majority of people, the gate will be created on application start and never modified again until the application shuts +down, in which case, you don't even need to worry about stopping the janitor. + +To avoid any misunderstandings, using a client provider is not mandatory. If you only have a few tokens and you can load +them on application start, you can just leverage `AuthorizationService`'s `WithToken`/`WithTokens`/`WithClient`/`WithClients`. + + +## AuthorizationService +As the previous examples may have hinted, there are several ways to create clients. The one thing they have +in common is that they all go through AuthorizationService, which is in charge of both managing clients and determining +whether a request should be blocked or allowed through. + +| Function | Description | +|:-------------------|:---------------------------------------------------------------------------------------------------------------------------------| +| WithToken | Creates a single static client with no extra permissions | +| WithTokens | Creates a slice of static clients with no extra permissions | +| WithClient | Creates a single static client | +| WithClients | Creates a slice of static clients | +| WithClientProvider | Creates a client provider which will allow a fallback to a dynamic source (e.g. to a database) when a static client is not found | + +Except for `WithClientProvider`, every functions listed above can be called more than once. +As a result, you may safely perform actions like this: +```go +authorizationService := g8.NewAuthorizationService(). + WithToken("123"). + WithToken("456"). + WithClient(g8.NewClient("789").WithPermission("admin")) +gate := g8.New().WithAuthorizationService(authorizationService) +``` + +Be aware that g8.Client supports a list of permissions as well. You may call `WithPermission` several times, or call +`WithPermissions` with a slice of permissions instead. + + +### Permissions +Unlike client permissions, handler permissions are requirements. + +A client may have as many permissions as you want, but for said client to have access to a handler protected by +permissions, the client must have all permissions defined by said handler in order to have access to it. + +In other words, a client with the permissions `create`, `read`, `update` and `delete` would have access to all of these handlers: +```go +gate := g8.New().WithAuthorizationService(g8.NewAuthorizationService().WithClient(g8.NewClient("mytoken").WithPermissions([]string{"create", "read", "update", "delete"}))) +router := http.NewServeMux() +router.Handle("/", gate.Protect(homeHandler)) // equivalent of gate.ProtectWithPermissions(homeHandler, []string{}) +router.Handle("/create", gate.ProtectWithPermissions(createHandler, []string{"create"})) +router.Handle("/read", gate.ProtectWithPermissions(readHandler, []string{"read"})) +router.Handle("/update", gate.ProtectWithPermissions(updateHandler, []string{"update"})) +router.Handle("/delete", gate.ProtectWithPermissions(deleteHandler, []string{"delete"})) +router.Handle("/crud", gate.ProtectWithPermissions(crudHandler, []string{"create", "read", "update", "delete"})) +``` +But it would not have access to the following handler, because while `mytoken` has the `read` permission, it does not +have the `backup` permission: +```go +router.Handle("/backup", gate.ProtectWithPermissions(&testHandler{}, []string{"read", "backup"})) +``` + +## Rate limiting +To add a rate limit of 100 requests per second: +``` +gate := g8.New().WithRateLimit(100) +``` + +## Special use cases +### Protecting a handler using session cookie +If you want to only allow authenticated users to access a handler, you can use a custom token extractor function +combined with a client provider. + +First, we'll create a function to extract the session ID from the session cookie. While a session ID does not +theoretically refer to a token, g8 uses the term `token` as a blanket term to refer to any string that can be used to +identify a client. +```go +customTokenExtractorFunc := func(request *http.Request) string { + sessionCookie, err := request.Cookie("session") + if err != nil { + return "" + } + return sessionCookie.Value +} +``` + +Next, we need to create a client provider that will validate our token, which refers to the session ID in this case. +```go +clientProvider := g8.NewClientProvider(func(token string) *g8.Client { + // We'll assume that the following function calls your database and validates whether the session is valid. + isSessionValid := database.CheckIfSessionIsValid(token) + if !isSessionValid { + return nil // Returning nil will cause the gate to return a 401 Unauthorized. + } + // You could also retrieve the user and their permissions if you wanted instead, but for this example, + // all we care about is confirming whether the session is valid or not. + return g8.NewClient(token) +}) +``` + +Keep in mind that you can get really creative with the client provider above. +For instance, you could refresh the session's expiration time, which will allow the user to stay logged in for +as long as they're active. + +You're also not limited to using something stateful like the example above. You could use a JWT and have your client +provider validate said JWT. + +Finally, we can create the authorization service and the gate: +```go +authorizationService := g8.NewAuthorizationService().WithClientProvider(clientProvider) +gate := g8.New().WithAuthorizationService(authorizationService).WithCustomTokenExtractor(customTokenExtractorFunc) +``` + +If you need to access the token (session ID in this case) from the protected handlers, you can retrieve it from the +request context by using the key `g8.TokenContextKey`: +```go +http.Handle("/handle",

+ + +## Persistence +Prior to v2, gocache supported persistence out of the box. + +After some thinking, I decided that persistence added too many dependencies, and given than this is a cache library +and most people wouldn't be interested in persistence, I decided to get rid of it. + +That being said, you can use the `GetAll` and `SetAll` methods of `gocache.Cache` to implement persistence yourself. + + +## Eviction +### MaxSize +Eviction by MaxSize is the default behavior, and is also the most efficient. + +The code below will create a cache that has a maximum size of 1000: +```go +cache := gocache.NewCache().WithMaxSize(1000) +``` +This means that whenever an operation causes the total size of the cache to go above 1000, the tail will be evicted. + +### MaxMemoryUsage +Eviction by MaxMemoryUsage is **disabled by default**, and is in alpha. + +The code below will create a cache that has a maximum memory usage of 50MB: +```go +cache := gocache.NewCache().WithMaxSize(0).WithMaxMemoryUsage(50*gocache.Megabyte) +``` +This means that whenever an operation causes the total memory usage of the cache to go above 50MB, one or more tails +will be evicted. + +Unlike evictions caused by reaching the MaxSize, evictions triggered by MaxMemoryUsage may lead to multiple entries +being evicted in a row. The reason for this is that if, for instance, you had 100 entries of 0.1MB each and you suddenly added +a single entry of 10MB, 100 entries would need to be evicted to make enough space for that new big entry. + +It's very important to keep in mind that eviction by MaxMemoryUsage is approximate. + +**The only memory taken into consideration is the size of the cache, not the size of the entire application.** +If you pass along 100MB worth of data in a matter of seconds, even though the cache's memory usage will remain +under 50MB (or whatever you configure the MaxMemoryUsage to), the memory footprint generated by that 100MB will +still exist until the next GC cycle. + +As previously mentioned, this is a work in progress, and here's a list of the things you should keep in mind: +- The memory usage of structs are a gross estimation and may not reflect the actual memory usage. +- Native types (string, int, bool, []byte, etc.) are the most accurate for calculating the memory usage. +- Adding an entry bigger than the configured MaxMemoryUsage will work, but it will evict all other entries. + + +## Expiration +There are two ways that the deletion of expired keys can take place: +- Active +- Passive + +**Active deletion of expired keys** happens when an attempt is made to access the value of a cache entry that expired. +`Get`, `GetByKeys` and `GetAll` are the only functions that can trigger active deletion of expired keys. + +**Passive deletion of expired keys** runs in the background and is managed by the janitor. +If you do not start the janitor, there will be no passive deletion of expired keys. + + +## Performance +### Summary +- **Set**: Both map and gocache have the same performance. +- **Get**: Map is faster than gocache. + +This is because gocache keeps track of the head and the tail for eviction and expiration/TTL. + +Ultimately, the difference is negligible. + +We could add a way to disable eviction or disable expiration altogether just to match the map's performance, +but if you're looking into using a library like gocache, odds are, you want more than just a map. + + +### Results +| key | value | +|:------ |:-------- | +| goos | windows | +| goarch |

might come in handy, it may still lead to loss of data if the application +automatically saves every 10 minutes and your application crashes 9 minutes after the previous save. + +To increase your odds of not losing any data, you can use Go's `signal` package, more specifically its `Notify` function +which allows listening for termination signals like SIGTERM and SIGINT. Once a termination signal is caught, you can +add the necessary logic for a graceful shutdown. + +In the following example, the code that would usually be present in the `main` function is moved to a different function +named `Start` which is launched on a different goroutine so that listening for a termination signals is what blocks the +main goroutine instead: +```go +package main + +import ( + "log" + "os" + "os/signal" + "syscall" + + "github.com/TwiN/gocache/v2" +) + +var cache = gocache.NewCache() + +func main() { + data := retrieveCacheEntriesUsingWhateverMeanYouUsedToPersistIt() + cache.SetAll(data) + // Start everything else on another goroutine to prevent blocking the main goroutine + go Start() + // Wait for termination signal + sig := make(chan os.Signal, 1) + done := make(chan bool, 1) + signal.Notify(sig, os.Interrupt, syscall.SIGTERM) + go func() { + <-sig + log.Println("Received termination signal, attempting to gracefully shut down") + // Persist the cache entries + cacheEntries := cache.GetAll() + persistCacheEntriesHoweverYouWant(cacheEntries) + // Tell the main goroutine that we're done + done <- true + }() + <-done + log.Println("Shutting down") +} +``` + +Note that this won't protect you from a SIGKILL, as this signal cannot be caught. diff --git a/vendor/github.com/TwiN/gocache/v2/entry.go b/vendor/github.com/TwiN/gocache/v2/entry.go new file

This includes support for JSON Web Encryption, +JSON Web Signature, and JSON Web Token standards. + +**Disclaimer**: This library contains encryption software that is subject to +the U.S. Export Administration Regulations. You may not export, re-export, +transfer or download this code or any part of it in violation of any United +States law, directive or regulation. In particular this software may not be +exported or re-exported in any form or on any media to Iran, North Sudan, +Syria, Cuba, or North Korea, or to denied persons or entities mentioned on any +US maintained blocked list. + +## Overview + +The implementation follows the +[JSON Web Encryption](http://dx.doi.org/10.17487/RFC7516) (RFC 7516), +[JSON Web Signature](http://dx.doi.org/10.17487/RFC7515) (RFC 7515), and +[JSON Web Token](http://dx.doi.org/10.17487/RFC7519) (RFC 7519). +Tables of supported algorithms are shown below. The library supports both +the compact and full serialization formats, and has optional support for +multiple recipients. It also comes with a small command-line utility +([`jose-util`](https://github.com/square/go-jose/tree/v2/jose-util)) +for dealing with JOSE messages in a shell. + +**Note**: We use a forked version of the `encoding/json` package from the Go +standard library which uses case-sensitive matching for member names (instead +of [case-insensitive matching](https://www.ietf.org/mail-archive/web/json/current/msg03763.html)). +This is to avoid differences in interpretation of messages between go-jose and +libraries in other languages. + +### Versions + +We use [gopkg.in](https://gopkg.in) for versioning. + +[Version 2](https://gopkg.in/square/go-jose.v2) +([branch](https://github.com/square/go-jose/tree/v2), +[doc](https://godoc.org/gopkg.in/square/go-jose.v2)) is the current version: + + import "gopkg.in/square/go-jose.v2" + +The old `v1` branch ([go-jose.v1](https://gopkg.in/square/go-jose.v1)) will +still receive backported bug fixes and security fixes, but otherwise +development is frozen.

If no MarshalJSON method is present but the +// value implements encoding.TextMarshaler instead, Marshal calls +// its MarshalText method. +// The nil pointer exception is not strictly necessary +// but mimics a similar, necessary exception in the behavior of +// UnmarshalJSON. +// +// Otherwise, Marshal uses the following type-dependent default encodings: +// +// Boolean values encode as JSON booleans. +// +// Floating point, integer, and Number values encode as JSON numbers. +// +// String values encode as JSON strings coerced to valid UTF-8, +// replacing invalid bytes with the Unicode replacement rune. +// The angle brackets "<" and ">" are escaped to "\u003c" and "\u003e" +// to keep some browsers from misinterpreting JSON output as HTML. +// Ampersand "&" is also escaped to "\u0026" for the same reason. +// +// Array and slice values encode as JSON arrays, except that +// []byte encodes as a base64-encoded string, and a nil slice +// encodes as the null JSON object. +// +// Struct values encode as JSON objects. Each exported struct field +// becomes a member of the object unless +// - the field's tag is "-", or +// - the field is empty and its tag specifies the "omitempty" option. +// The empty values are false, 0, any +// nil pointer or interface value, and any array, slice, map, or string of +// length zero. The object's default key string is the struct field name +// but can be specified in the struct field's tag value. The "json" key in +// the struct field's tag value is the key name, followed by an optional comma +// and options. Examples: +// +// // Field is ignored by this package. +// Field int `json:"-"` +// +// // Field appears in JSON as key "myName". +// Field int `json:"myName"` +// +// // Field appears in JSON as key "myName" and +// // the field is omitted from the object if its value is empty, +// // as defined above. +// Field int `json:"myName,omitempty"` +// +// // Field appears in JSON as key "Field" (the default), but +// // the field is skipped if empty. +// // Note the leading comma. +// Field int `json:",omitempty"` +// +// The "string" option signals that a field is stored as JSON inside a +// JSON-encoded string. It applies only to fields of string, floating point, +// integer, or boolean types. This extra level of encoding is sometimes used +// when communicating with JavaScript programs: +// +// Int64String int64 `json:",string"` +// +// The key name will be used if it's a non-empty string consisting of +// only Unicode letters, digits, dollar signs, percent signs, hyphens, +// underscores and slashes. +// +// Anonymous struct fields are usually marshaled as if their inner exported fields +// were fields in the outer struct, subject to the usual Go visibility rules amended +// as described in the next paragraph. +// An anonymous struct field with a name given in its JSON tag is treated as +// having that name, rather than being anonymous. +// An anonymous struct field of interface type is treated the same as having +// that type as its name, rather than being anonymous. +// +// The Go visibility rules for struct fields are amended for JSON when +// deciding which field to marshal or unmarshal. If there are +// multiple fields at the same level, and that level is the least +// nested (and would therefore be the nesting level selected by the +// usual Go rules), the following extra rules apply: +// +// 1) Of those fields, if any are JSON-tagged, only tagged fields are considered, +// even if there are multiple untagged fields that would otherwise conflict. +// 2) If there is exactly one field (tagged or not according to the first rule), that is selected. +// 3) Otherwise there are multiple fields, and all are ignored; no error occurs. +// +// Handling of anonymous struct fields is new in Go 1.1. +// Prior to Go 1.1, anonymous struct fields were ignored. To force ignoring of +// an anonymous struct field in both current and earlier versions, give the field +// a JSON tag of "-". +// +// Map values encode as JSON objects. +// The map's key type must be string; the map keys are used as JSON object +// keys, subject to the UTF-8 coercion described for string values above. +// +// Pointer values encode as the value pointed to. +// A nil pointer encodes as the null JSON object. +// +// Interface values encode as the value contained in the interface. +// A nil interface value encodes as the null JSON object. +// +// Channel, complex, and function values cannot be encoded in JSON. +// Attempting to encode such a value causes Marshal to return +// an UnsupportedTypeError. +// +// JSON cannot represent cyclic data structures and Marshal does not +// handle them.
