# Pluggable Cache System for htmgo
|
||||
|
||||
## Overview
|
||||
|
||||
The htmgo framework now supports a pluggable cache system that allows developers to provide their own caching
|
||||
implementations. This addresses potential memory exhaustion vulnerabilities in the previous TTL-only caching approach
|
||||
and provides greater flexibility for production deployments.
|
||||
|
||||
## Motivation
|
||||
|
||||
The previous caching mechanism relied exclusively on Time-To-Live (TTL) expiration, which could lead to:
|
||||
|
||||
- **Unbounded memory growth**: High-cardinality cache keys could consume all available memory
|
||||
- **DDoS vulnerability**: Attackers could exploit this by generating many unique cache keys
|
||||
- **Limited flexibility**: No support for size-bounded caches or distributed caching solutions
|
||||
|
||||
## Architecture
|
||||
|
||||
The new system introduces a generic `Store[K comparable, V any]` interface:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import "time"
|
||||
|
||||
type Store[K comparable, V any] interface {
|
||||
// Set adds or updates an entry in the cache with the given TTL
|
||||
Set(key K, value V, ttl time.Duration)
|
||||
|
||||
// GetOrCompute atomically gets an existing value or computes and stores a new value
|
||||
// This prevents duplicate computation when multiple goroutines request the same key
|
||||
GetOrCompute(key K, compute func() V, ttl time.Duration) V
|
||||
|
||||
// Delete removes an entry from the cache
|
||||
Delete(key K)
|
||||
|
||||
// Purge removes all items from the cache
|
||||
Purge()
|
||||
|
||||
// Close releases any resources used by the cache
|
||||
Close()
|
||||
}
|
||||
```
|
||||
|
||||
### Atomic Guarantees
|
||||
|
||||
The `GetOrCompute` method provides **atomic guarantees** to prevent cache stampedes and duplicate computations:
|
||||
- When multiple goroutines request the same uncached key simultaneously, only one will execute the compute function
|
||||
- Other goroutines will wait and receive the computed result
|
||||
- This eliminates race conditions that could cause duplicate expensive operations like database queries or renders
|
||||
|
||||
## Usage
|
||||
|
||||
### Using the Default Cache
|
||||
|
||||
By default, htmgo continues to use a TTL-based cache for backward compatibility:
|
||||
|
||||
```go
|
||||
// No changes needed - works exactly as before
|
||||
UserProfile := h.CachedPerKeyT(
|
||||
15*time.Minute,
|
||||
func(userID int) (int, h.GetElementFunc) {
|
||||
return userID, func() *h.Element {
|
||||
return h.Div(h.Text("User profile"))
|
||||
}
|
||||
},
|
||||
)
|
||||
```
|
||||
|
||||
### Using a Custom Cache
|
||||
|
||||
You can provide your own cache implementation using the `WithCacheStore` option:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/maddalax/htmgo/framework/h"
|
||||
"github.com/maddalax/htmgo/framework/h/cache"
|
||||
"time"
|
||||
)
|
||||
|
||||
var (
|
||||
// Create a memory-bounded LRU cache
|
||||
lruCache = cache.NewLRUStore[any, string](10_000) // Max 10,000 items
|
||||
|
||||
// Use it with a cached component
|
||||
UserProfile = h.CachedPerKeyT(
|
||||
15*time.Minute,
|
||||
func (userID int) (int, h.GetElementFunc) {
|
||||
return userID, func () *h.Element {
|
||||
return h.Div(h.Text("User profile"))
|
||||
}
|
||||
},
|
||||
h.WithCacheStore(lruCache), // Pass the custom cache
|
||||
)
|
||||
)
|
||||
```
|
||||
|
||||
### Changing the Default Cache Globally
|
||||
|
||||
You can override the default cache provider for your entire application:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/maddalax/htmgo/framework/h"
|
||||
"github.com/maddalax/htmgo/framework/h/cache"
|
||||
)
|
||||
|
||||
func init() {
|
||||
// All cached components will use LRU by default
|
||||
h.DefaultCacheProvider = func () cache.Store[any, string] {
|
||||
return cache.NewLRUStore[any, string](50_000)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Example Implementations
|
||||
|
||||
### Built-in Stores
|
||||
|
||||
1. **TTLStore** (default): Time-based expiration with periodic cleanup
|
||||
2. **LRUStore** (example): Least Recently Used eviction with size limits
|
||||
|
||||
### Integrating Third-Party Libraries
|
||||
|
||||
Here's an example of integrating the high-performance `go-freelru` library:
|
||||
|
||||
```go
|
||||
import (
|
||||
"time"
|
||||
"github.com/elastic/go-freelru"
|
||||
"github.com/maddalax/htmgo/framework/h/cache"
|
||||
)
|
||||
|
||||
type FreeLRUAdapter[K comparable, V any] struct {
|
||||
lru *freelru.LRU[K, V]
|
||||
}
|
||||
|
||||
func NewFreeLRUAdapter[K comparable, V any](size uint32) cache.Store[K, V] {
|
||||
lru, err := freelru.New[K, V](size, nil)
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}

### Redis-based Distributed Cache
|
||||
|
||||
```go
|
||||
type RedisStore struct {
|
||||
client *redis.Client
|
||||
prefix string
|
||||
}
|
||||
|
||||
func (s *RedisStore) Set(key any, value string, ttl time.Duration) {
|
||||
keyStr := fmt.Sprintf("%s:%v", s.prefix, key)
|
||||
s.client.Set(context.Background(), keyStr, value, ttl)
|
||||
}
|
||||
|
||||
func (s *RedisStore) GetOrCompute(key any, compute func() string, ttl time.Duration) string {
|
||||
keyStr := fmt.Sprintf("%s:%v", s.prefix, key)
|
||||
ctx := context.Background()
|
||||
|
||||
// Try to get from Redis
|
||||
val, err := s.client.Get(ctx, keyStr).Result()
|
||||
if err == nil {
|
||||
return val
|
||||
}
|
||||
|
||||
// Not in cache, compute new value
|
||||
// For true atomic guarantees, use Redis SET with NX option
|
||||
value := compute()
|

s.client.Set(ctx, keyStr, value, ttl)
|
||||
return value
|
||||

|
||||
|
||||
// ... implement other methods
|

```

||||
|
||||
## Migration Guide
|
||||
|
||||
### For Existing Applications
|
||||
|
||||
The changes are backward compatible. Existing applications will continue to work without modifications. The function
|
||||
signatures now accept optional `CacheOption` parameters, but these can be omitted.
|
||||
|
||||
### Recommended Migration Path
|
||||
|
||||
1. **Assess your caching needs**: Determine if you need memory bounds or distributed caching
|
||||
2. **Choose an implementation**: Use the built-in LRUStore or integrate a third-party library
|
||||
3. **Update critical components**: Start with high-traffic or high-cardinality cached components
|
||||
4. **Monitor memory usage**: Ensure your cache size limits are appropriate
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Memory-Bounded Caches
|
||||
|
||||
For public-facing applications, we strongly recommend using a memory-bounded cache to prevent DoS attacks:
|
||||
|
||||
```go
|
||||
// Limit cache to reasonable size based on your server's memory
|
||||
cache := cache.NewLRUStore[any, string](100_000)
|
||||
|
||||
// Use for all user-specific caching
|
||||
UserContent := h.CachedPerKey(
|
||||
5*time.Minute,
|
||||
getUserContent,
|
||||
h.WithCacheStore(cache),
|
||||
)
|
||||
```
|
||||
|
||||
### Cache Key Validation
|
||||
|
||||
When using user input as cache keys, always validate and sanitize:
|
||||
|
||||
```go
|
||||
func cacheKeyForUser(userInput string) string {
|
||||
// Limit length and remove special characters
|
||||
key := strings.TrimSpace(userInput)
|
||||
if len(key) > 100 {
|
||||
key = key[:100]
|
||||
}
|
||||
return regexp.MustCompile(`[^a-zA-Z0-9_-]`).ReplaceAllString(key, "")
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
1. **TTLStore**: Best for small caches with predictable key patterns
|
||||
2. **LRUStore**: Good general-purpose choice with memory bounds
|
||||
3. **Third-party stores**: Consider `go-freelru` or `theine-go` for high-performance needs
|
||||
4. **Distributed stores**: Use Redis/Memcached for multi-instance deployments
|
||||
5. **Atomic Operations**: The `GetOrCompute` method prevents duplicate computations, significantly improving performance under high concurrency
|
||||
|
||||
### Concurrency Benefits
|
||||
|
||||
The atomic `GetOrCompute` method provides significant performance benefits:
|
||||
- **Prevents Cache Stampedes**: When a popular cache entry expires, only one goroutine will recompute it
|
||||
- **Reduces Load**: Expensive operations (database queries, API calls, complex renders) are never duplicated
|
||||
- **Improves Response Times**: Waiting goroutines get results faster than computing themselves
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Set appropriate cache sizes**: Balance memory usage with hit rates
|
||||
2. **Use consistent TTLs**: Align with your data update patterns
|
||||
3. **Monitor cache metrics**: Track hit rates, evictions, and memory usage
|
||||
4. **Handle cache failures gracefully**: Caches should enhance, not break functionality
|
||||
5. **Close caches properly**: Call `Close()` during graceful shutdown
|
||||
6. **Implement atomic guarantees**: Ensure your `GetOrCompute` implementation prevents concurrent computation
|
||||
7. **Test concurrent access**: Verify your cache handles simultaneous requests correctly
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- Built-in metrics and monitoring hooks
|
||||
- Automatic size estimation for cached values
|
||||
- Warming and preloading strategies
|
||||
- Cache invalidation patterns

<b>Security Note:</b> The pluggable cache system helps mitigate memory exhaustion attacks by allowing

<b>Concurrency Note:</b> The GetOrCompute method eliminates race conditions that could occur

in the previous implementation. When multiple goroutines request the same uncached key via

GetOrCompute method simultaneously, only one will execute the expensive render operation,

while others wait for the result. This prevents "cache stampedes" where many goroutines
