6a8c308af7 fix(api): Define unprotected routes first
This is because fiber does not work the same way that mux did wrt groups (mux referred to them as subrouters).
I could not apply a middleware to a specific fiber Group due to the groups being prefix-based.
In other words, the only other way to apply middlewares to specific endpoints without changing the path is by applying the security middleware after the routes that did not need to be protected and before the routes that did need to be protected

6ab8899dc6 fix(condition): Partially support numbers with floating point (#434)
* docs: Don't include Pushover in alerting provider examples

* fix(condition): Partially support numbers with floating point

Fixes #433

Does not add support for decimal numbers, but it converts float64 to int64.
The reason why I'm not just using float64 instead of int64 is because float64 does not support all the numbers that int64 supports, which means this would be a breaking change. Instead, this change at least supports the non-decimal part of floating point numbers.

This is an improvement over the current implementation, as right now, numbers with decimals are just converted to 0 when compared using a non-equal operator

Gatus is a developer-oriented health dashboard that gives you the ability to monitor your services using HTTP, ICMP, TCP, and even DNS
queries as well as evaluate the result of said queries by using a list of conditions on values like the status code,
the response time, the certificate expiration, the body and many others. The icing on top is that each of these health
checks can be paired with alerting via Slack, PagerDuty, Discord, Twilio and more.

Note that you can also use environment variables in the configuration file (e.g. `$DOMAIN`, `${DOMAIN}`)
By default, the configuration file is expected to be at `config/config.yaml`.
You can specify a custom path by setting the `GATUS_CONFIG_PATH` environment variable.
If `GATUS_CONFIG_PATH` points to a directory, all `*.yaml` and `*.yml` files inside said directory and its
subdirectories are merged like so:
- All maps/objects are deep merged (i.e. you could define `alerting.slack` in one file and `alerting.pagerduty` in another file)
- All slices/arrays are appended (i.e. you can define `endpoints` in multiple files and each endpoint will be added to the final list of endpoints)
- Parameters with a primitive value (e.g. `debug`, `metrics`, `alerting.slack.webhook-url`, etc.) may only be defined once to forcefully avoid any ambiguity
- To clarify, this also means that you could not define `alerting.slack.webhook-url` in two files with different values. All files are merged into one before they are processed. This is by design.

g8, pronounced gate, is a simple Go library for protecting HTTP handlers.
Tired of constantly re-implementing a security layer for each application? Me too, that's why I made g8.
## Installation
```console
go get -u github.com/TwiN/g8
```
## Usage
Because the entire purpose of g8 is to NOT waste time configuring the layer of security, the primary emphasis is to
keep it as simple as possible.
### Simple
Just want a simple layer of security without the need for advanced permissions? This configuration is what you're
looking for.
```go
authorizationService := g8.NewAuthorizationService().WithToken("mytoken")
gate := g8.New().WithAuthorizationService(authorizationService)
router := http.NewServeMux()
router.Handle("/unprotected", yourHandler)
router.Handle("/protected", gate.Protect(yourHandler))
http.ListenAndServe(":8080", router)
```
The endpoint `/protected` is now only accessible if you pass the header `Authorization: Bearer mytoken`.
If you use `http.HandleFunc` instead of `http.Handle`, you may use `gate.ProtectFunc(yourHandler)` instead.
If you're not using the `Authorization` header, you can specify a custom token extractor.
This enables use cases like [Protecting a handler using session cookie](#protecting-a-handler-using-session-cookie)
### Advanced permissions
If you have tokens with more permissions than others, g8's permission system will make managing authorization a breeze.
Rather than registering tokens, think of it as registering clients, the only difference being that clients may be
configured with permissions while tokens cannot.
```go
authorizationService := g8.NewAuthorizationService().WithClient(g8.NewClient("mytoken").WithPermission("admin"))
gate := g8.New().WithAuthorizationService(authorizationService)
router := http.NewServeMux()
router.Handle("/unprotected", yourHandler)
router.Handle("/protected-with-admin", gate.ProtectWithPermissions(yourHandler, []string{"admin"}))
http.ListenAndServe(":8080", router)
```
The endpoint `/protected-with-admin` is now only accessible if you pass the header `Authorization: Bearer mytoken`,
because the client with the token `mytoken` has the permission `admin`. 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"}))
```
If you're using an HTTP library that supports middlewares like [mux](https://github.com/gorilla/mux), you can protect
an entire group of handlers instead using `gate.Protect` or `gate.PermissionMiddleware()`:
```go
router := mux.NewRouter()
userRouter := router.PathPrefix("/").Subrouter()
userRouter.Use(gate.Protect)
userRouter.HandleFunc("/api/v1/users/me", getUserProfile).Methods("GET")
userRouter.HandleFunc("/api/v1/users/me/friends", getUserFriends).Methods("GET")
userRouter.HandleFunc("/api/v1/users/me/email", updateUserEmail).Methods("PATCH")
adminRouter := router.PathPrefix("/").Subrouter()
adminRouter.Use(gate.PermissionMiddleware("admin"))
adminRouter.HandleFunc("/api/v1/users/{id}/ban", banUserByID).Methods("POST")
adminRouter.HandleFunc("/api/v1/users/{id}/delete", deleteUserByID).Methods("DELETE")
```
## Rate limiting
To add a rate limit of 100 requests per second:
```go
gate := g8.New().WithRateLimit(100)
```
## Accessing the token from the protected handlers
If you need to access the token from the handlers you are protecting with g8, you can retrieve it from the
request context by using the key `g8.TokenContextKey`:
```go
http.Handle("/handle", gate.ProtectFunc(func(w http.ResponseWriter, r *http.Request) {
token, _ := r.Context().Value(g8.TokenContextKey).(string)
// ...
}))
```
## Examples
### 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", gate.ProtectFunc(func(w http.ResponseWriter, r *http.Request) {
sessionID, _ := r.Context().Value(g8.TokenContextKey).(string)
// ...
}))
```
### Using a custom header
The logic is the same as the example above:
```go
customTokenExtractorFunc := func(request *http.Request) string {
return request.Header.Get("X-API-Token")
}
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).WithCustomTokenExtractor(customTokenExtractorFunc)
```

gocache is an easy-to-use, high-performance, lightweight and thread-safe (goroutine-safe) in-memory key-value cache
with support for LRU and FIFO eviction policies as well as expiration, bulk operations and even retrieval of keys by pattern.

## Features
gocache supports the following cache eviction policies:
- First in first out (FIFO)
- Least recently used (LRU)
It also supports cache entry TTL, which is both active and passive. Active expiration means that if you attempt
to retrieve a cache key that has already expired, it will delete it on the spot and the behavior will be as if
the cache key didn't exist. As for passive expiration, there's a background task that will take care of deleting
expired keys.
It also includes what you'd expect from a cache, like GET/SET, bulk operations and get by pattern.
## Usage
```
go get -u github.com/TwiN/gocache/v2
```
### Initializing the cache
```go
cache := gocache.NewCache().WithMaxSize(1000).WithEvictionPolicy(gocache.LeastRecentlyUsed)
```
If you're planning on using expiration (`SetWithTTL` or `Expire`) and you want expired entries to be automatically deleted
in the background, make sure to start the janitor when you instantiate the cache:
```go
cache.StartJanitor()
```
### Functions
| Function | Description |
|-----------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| WithMaxSize | Sets the max size of the cache. `gocache.NoMaxSize` means there is no limit. If not set, the default max size is `gocache.DefaultMaxSize`. |
| WithMaxMemoryUsage | Sets the max memory usage of the cache. `gocache.NoMaxMemoryUsage` means there is no limit. The default behavior is to not evict based on memory usage. |
| WithEvictionPolicy | Sets the eviction algorithm to be used when the cache reaches the max size. If not set, the default eviction policy is `gocache.FirstInFirstOut` (FIFO). |
| WithDefaultTTL | Sets the default TTL for each entry. |
| WithForceNilInterfaceOnNilPointer | Configures whether values with a nil pointer passed to write functions should be forcefully set to nil. Defaults to true. |
| StartJanitor | Starts the janitor, which is in charge of deleting expired cache entries in the background. |
| StopJanitor | Stops the janitor. |
| Set | Same as `SetWithTTL`, but using the default TTL (which is `gocache.NoExpiration`, unless configured otherwise). |
| SetWithTTL | Creates or updates a cache entry with the given key, value and expiration time. If the max size after the aforementioned operation is above the configured max size, the tail will be evicted. Depending on the eviction policy, the tail is defined as the oldest |
| SetAll | Same as `Set`, but in bulk. |
| SetAllWithTTL | Same as `SetWithTTL`, but in bulk. |
| Get | Gets a cache entry by its key. |
| GetByKeys | Gets a map of entries by their keys. The resulting map will contain all keys, even if some of the keys in the slice passed as parameter were not present in the cache. |
| GetAll | Gets all cache entries. |
| GetKeysByPattern | Retrieves a slice of keys that matches a given pattern. |
| Delete | Removes a key from the cache. |
| DeleteAll | Removes multiple keys from the cache. |
| DeleteKeysByPattern | Removes all keys that that matches a given pattern. |
| Count | Gets the size of the cache. This includes cache keys which may have already expired, but have not been removed yet. |
| Clear | Wipes the cache. |
| TTL | Gets the time until a cache key expires. |
| Expire | Sets the expiration time of an existing cache key. |
For further documentation, please refer to [Go Reference](https://pkg.go.dev/github.com/TwiN/gocache)
### Examples
#### Creating or updating an entry
```go
cache.Set("key", "value")
cache.Set("key", 1)
cache.Set("key", struct{ Text string }{Test: "value"})
cache.SetWithTTL("key", []byte("value"), 24*time.Hour)
```
#### Getting an entry
```go
value, exists := cache.Get("key")
```
You can also get multiple entries by using `cache.GetByKeys([]string{"key1", "key2"})`
#### Deleting an entry
```go
cache.Delete("key")
```
You can also delete multiple entries by using `cache.DeleteAll([]string{"key1", "key2"})`
#### Complex example
```go
package main
import (
"fmt"
"time"
"github.com/TwiN/gocache/v2"
)
func main() {
cache := gocache.NewCache().WithEvictionPolicy(gocache.LeastRecentlyUsed).WithMaxSize(10000)
cache.StartJanitor() // Passively manages expired entries
defer cache.StopJanitor()
cache.Set("key", "value")
cache.SetWithTTL("key-with-ttl", "value", 60*time.Minute)
cache.SetAll(map[string]any{"k1": "v1", "k2": "v2", "k3": "v3"})
fmt.Println("[Count] Cache size:", cache.Count())
value, exists := cache.Get("key")
fmt.Printf("[Get] key=key; value=%s; exists=%v\n", value, exists)
for key, value := range cache.GetByKeys([]string{"k1", "k2", "k3"}) {
fmt.Printf("[GetByKeys] key=%s; value=%s\n", key, value)
}
for _, key := range cache.GetKeysByPattern("key*", 0) {
fmt.Printf("[GetKeysByPattern] pattern=key*; key=%s\n", key)
}
cache.Expire("key", time.Hour)
time.Sleep(500*time.Millisecond)
timeUntilExpiration, _ := cache.TTL("key")
fmt.Println("[TTL] Number of minutes before 'key' expires:", int(timeUntilExpiration.Seconds()))
cache.Delete("key")
cache.DeleteAll([]string{"k1", "k2", "k3"})
cache.Clear()
fmt.Println("[Count] Cache size after clearing the cache:", cache.Count())
}
```
<details>
<summary>Output</summary>
```
[Count] Cache size: 5
[Get] key=key; value=value; exists=true
[GetByKeys] key=k1; value=v1
[GetByKeys] key=k2; value=v2
[GetByKeys] key=k3; value=v3
[GetKeysByPattern] pattern=key*; key=key-with-ttl
[GetKeysByPattern] pattern=key*; key=key
[TTL] Number of minutes before 'key' expires: 3599
[Count] Cache size after clearing the cache: 0
```
</details>
## 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.

## FAQ
### How can I persist the data on application termination?
While creating your own auto save feature 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.

// LeastRecentlyUsed is an eviction policy that causes the most recently accessed cache entry to be moved to the
// head of the cache. Effectively, this causes the cache entries that have not been accessed for some time to
// gradually move closer and closer to the tail, and since the tail is the entry that gets deleted when an eviction
// is required, it allows less used cache entries to be evicted while keeping recently accessed entries at or close
// to the head.
//
// For instance, creating a Cache with a Cache.MaxSize of 3 and creating the entries 1, 2 and 3 in that order would
// put 3 at the head and 1 at the tail:
// 3 (head) -> 2 -> 1 (tail)
// If the cache entry 1 was then accessed, 1 would become the head and 2 the tail:
// 1 (head) -> 3 -> 2 (tail)
// If a cache entry 4 was then created, because the Cache.MaxSize is 3, the tail (2) would then be evicted:
// 4 (head) -> 1 -> 3 (tail)
