## Installation
## Example of implementation
We will work on an example of file/folder tree like this :
```bash
/
bin/
api/
config/
routers/
static/
get.go
static/
static/
...some_static_files...
go get github.com/nabbar/golib/static
```
in the `get.go` file, we will implement the static package call :

## Quick Start
### Minimum Go Version
**Go 1.21+** is required for:
- `embed.FS` and `//go:embed` directive (Go 1.16)
- Generics support for type-safe atomic wrappers (Go 1.18)
- `atomic.Int64`/`atomic.Uint64` types with methods (Go 1.19)
- `slices.Contains()` from standard library (Go 1.21)
### Basic Usage
```go
package static
package main
import (
"context"
"embed"
"github.com/gin-gonic/gin"
"github.com/gobuffalo/packr"
"github.com/nabbar/golib/static"
"myapp/release"
"myapp/bin/api/config"
"myapp/bin/api/routers"
"github.com/nabbar/golib/static"
)
const UrlPrefix = "/static"
//go:embed public
var publicFS embed.FS
func init() {
staticStcFile := static.NewStatic(false, UrlPrefix, packr.NewBox("../../../../static/static"), GetHeader)
staticStcFile.SetDownloadAll()
staticStcFile.Register(routers.RouterList.Register)
func main() {
// Create static handler
handler := static.New(context.Background(), publicFS, "public")
// Configure security
handler.SetPathSecurity(static.DefaultPathSecurityConfig())
handler.SetRateLimit(static.DefaultRateLimitConfig())
// Setup Gin router
router := gin.Default()
handler.RegisterRouter("/static", router.GET)
router.Run(":8080")
}
```
func GetHeader(c *gin.Context) {
// any function to return global & generic header (like CSP, HSTS, ...)
}
### With Security Integration
```go
handler := static.New(ctx, fs, "assets")
// Path security
handler.SetPathSecurity(static.PathSecurityConfig{
Enabled: true,
AllowDotFiles: false,
MaxPathDepth: 10,
BlockedPatterns: []string{".git", ".env"},
})
// Rate limiting
handler.SetRateLimit(static.RateLimitConfig{
Enabled: true,
MaxRequests: 100,
Window: time.Minute,
})
// WAF integration
handler.SetSecurityBackend(static.SecurityConfig{
Enabled: true,
WebhookURL: "https://waf.example.com/events",
MinSeverity: "medium",
})
```
### Advanced Configuration
```go
// HTTP caching
handler.SetHeaders(static.HeadersConfig{
EnableCacheControl: true,
CacheMaxAge: 3600,
CachePublic: true,
EnableETag: true,
DenyMimeTypes: []string{"application/x-executable"},
})
// Suspicious access detection
handler.SetSuspicious(static.SuspiciousConfig{
Enabled: true,
SuspiciousPatterns: []string{
".env", ".git", "wp-admin",
},
})
// Index files
handler.SetIndex("", "/", "index.html")
handler.SetIndex("", "/docs", "docs/index.html")
// Downloads
handler.SetDownload("/files/document.pdf", true)
// Redirects
handler.SetRedirect("", "/old-path", "", "/new-path")
```

## Use Cases
### 1. Single Page Application (SPA)
```go
handler := static.New(ctx, embedFS, "dist")
// Security
handler.SetPathSecurity(static.DefaultPathSecurityConfig())
// Aggressive caching for immutable assets
handler.SetHeaders(static.HeadersConfig{
EnableCacheControl: true,
CacheMaxAge: 31536000, // 1 year
CachePublic: true,
EnableETag: true,
})
// Index file for all routes (SPA routing)

---
## Best Practices
### ✅ DO
```go
// Use default configurations as starting point
handler.SetPathSecurity(static.DefaultPathSecurityConfig())
handler.SetRateLimit(static.DefaultRateLimitConfig())
// Enable ETag for bandwidth savings
handler.SetHeaders(static.HeadersConfig{
EnableETag: true,
CacheMaxAge: 3600,
})
// Use batch processing for high-volume security events
handler.SetSecurityBackend(static.SecurityConfig{
Enabled: true,
BatchSize: 100,
BatchTimeout: 30 * time.Second,
})
// Whitelist localhost for development
handler.SetRateLimit(static.RateLimitConfig{
WhitelistIPs: []string{"127.0.0.1", "::1"},
})
// Set appropriate cache duration per asset type
handler.SetHeaders(static.HeadersConfig{
CacheMaxAge: 31536000, // 1 year for versioned assets
})
```
### ❌ DON'T
```go
// Don't disable all security in production
handler.SetPathSecurity(static.PathSecurityConfig{
Enabled: false, // ❌ Unsafe
})
// Don't allow dot files in production
handler.SetPathSecurity(static.PathSecurityConfig{
AllowDotFiles: true, // ❌ Exposes .env, .git
})
// Don't set unlimited rate limit
handler.SetRateLimit(static.RateLimitConfig{
MaxRequests: 0, // ❌ No protection
})
// Don't use sync webhooks in high-traffic scenarios
handler.SetSecurityBackend(static.SecurityConfig{
WebhookAsync: false, // ❌ Blocks requests
})
// Don't forget cleanup interval
handler.SetRateLimit(static.RateLimitConfig{
CleanupInterval: 0, // ❌ Memory leak
})
```
### Security Recommendations
1. **Always enable path security** - Even in development
2. **Use rate limiting** - Protect against DoS attacks
3. **Enable suspicious detection** - Identify attack patterns early
4. **Integrate with SIEM** - Use webhook or CEF for monitoring
5. **Regular cleanup** - Configure CleanupInterval for rate limiter
6. **Whitelist carefully** - Only trusted IPs should bypass limits
7. **Block dangerous MIME types** - Prevent executable uploads
8. **Use batch processing** - Reduce security backend overhead
### Performance Recommendations
1. **Enable ETag** - Reduces bandwidth significantly
2. **Use CDN** - Offload static file delivery
3. **Appropriate cache TTL** - Balance freshness vs. performance
4. **Async webhooks** - Non-blocking security event delivery
5. **Batch events** - Reduce webhook call overhead
6. **Monitor throughput** - Use built-in benchmarks

## Quick Start
```bash
# Install Ginkgo CLI (optional)
go install github.com/onsi/ginkgo/v2/ginkgo@latest
# Run all tests
go test -v
# With coverage
go test -v -cover -coverprofile=coverage.out
# With race detector
CGO_ENABLED=1 go test -race
# Generate HTML coverage report
go tool cover -html=coverage.out -o coverage.html
# Using Ginkgo CLI
ginkgo -r --cover --race
```
---
## Test Framework
### Ginkgo & Gomega
The test suite uses **Ginkgo v2** for BDD-style testing and **Gomega** for assertions.
```go
var _ = Describe("Static File Server", func() {
Context("when serving files", func() {
It("should return 200 OK for existing files", func() {
// Test implementation
Expect(statusCode).To(Equal(200))
})
})
})
```
### GinkgoRecover
All tests use `GinkgoRecover()` to prevent panics from crashing the test suite:
```go
BeforeEach(func() {
defer GinkgoRecover()
// Setup
})
```
### Gmeasure
Benchmarks use **gmeasure** for precise performance measurements:
```go
experiment := gmeasure.NewExperiment("File Operations")
experiment.Sample(func(idx int) {
experiment.MeasureDuration("operation", func() {
// Measured code
})
}, gmeasure.SamplingConfig{N: 100})
```

---
## Thread Safety
### Verification Methods
#### Race Detector
The test suite runs with `-race` flag to detect data races:
```bash
CGO_ENABLED=1 go test -race -count=10
```
**Results:** ✅ Zero races detected across 229 tests
#### Concurrency Tests
Dedicated concurrency tests verify thread safety:
```go
It("should handle concurrent requests safely", func() {
var wg sync.WaitGroup
errors := make([]error, 100)
for i := 0; i < 100; i++ {
wg.Add(1)
go func(idx int) {
defer wg.Done()
defer GinkgoRecover()
// Concurrent operations
handler.SetRateLimit(config)
handler.SetPathSecurity(config)
errors[idx] = handler.validatePath("/test")
}(i)
}
wg.Wait()
// Verify no errors
})
```
### Atomic Primitives
All shared state uses atomic operations:
```go
// Configuration (atomic.Value)
type staticHandler struct {
rlc libatm.Value[*RateLimitConfig]
psc libatm.Value[*PathSecurityConfig]
hdr libatm.Value[*HeadersConfig]
sec libatm.Value[*SecurityConfig]
sus libatm.Value[*SuspiciousConfig]
}
// IP tracking (atomic.Map)
rli libatm.MapTyped[string, *ipTrack]
// Counters (atomic.Int64, atomic.Uint64)
siz *atomic.Int64
seq *atomic.Uint64
```
### No Mutexes Required
The design uses **lock-free concurrency**:
- ✅ Atomic operations for all shared state
- ✅ Immutable configuration after set
- ✅ Read-only embedded filesystem
- ✅ Context-based configuration (libctx.Config)

## Writing Tests
### Test Structure Template
```go
var _ = Describe("Feature Name", func() {
var (
handler static.Static
engine *gin.Engine
)
BeforeEach(func() {
defer GinkgoRecover()
handler = newTestStatic()
engine = setupTestRouter(handler, "/static")
})
Context("when condition", func() {
It("should behave correctly", func() {
// Arrange
config := static.DefaultConfig()
// Act
handler.SetConfig(config)
result := performOperation()
// Assert
Expect(result).To(BeTrue())
})
})
})
```
### Assertions
```go
// Basic assertions
Expect(value).To(Equal(expected))
Expect(value).NotTo(BeNil())
Expect(value).To(BeTrue())
// Numeric comparisons
Expect(count).To(BeNumerically(">", 0))
Expect(duration).To(BeNumerically("~", expected, threshold))
// Strings
Expect(str).To(ContainSubstring("text"))
Expect(str).To(HavePrefix("prefix"))
// Errors
Expect(err).NotTo(HaveOccurred())
Expect(err).To(MatchError("expected error"))
// HTTP responses
Expect(w.Code).To(Equal(http.StatusOK))
Expect(w.Body.String()).To(ContainSubstring("content"))
Expect(w.Header().Get("ETag")).NotTo(BeEmpty())
```
### Test Helpers
```go
// Create test handler
func newTestStatic() interface{} {
return static.New(context.Background(), testContent, "testdata")
}
// Setup Gin router
func setupTestRouter(handler static.Static, path string) *gin.Engine {
gin.SetMode(gin.TestMode)
router := gin.New()
handler.RegisterRouter(path, router.GET)
return router
}
// Perform HTTP request
func performRequest(engine *gin.Engine, method, path string) *httptest.ResponseRecorder {
req := httptest.NewRequest(method, path, nil)
w := httptest.NewRecorder()
engine.ServeHTTP(w, req)
return w
}
// With custom headers
func performRequestWithHeaders(engine *gin.Engine, method, path string, headers map[string]string) *httptest.ResponseRecorder {
req := httptest.NewRequest(method, path, nil)
for k, v := range headers {
req.Header.Set(k, v)
}
w := httptest.NewRecorder()
engine.ServeHTTP(w, req)
return w
}
```
### Benchmark Template
```go
var _ = Describe("Benchmarks", func() {
var experiment *gmeasure.Experiment
BeforeEach(func() {
experiment = gmeasure.NewExperiment("Operation Name")
AddReportEntry(experiment.Name, experiment)
})
It("should benchmark operation", func() {
handler := newTestStatic().(static.Static)
experiment.Sample(func(idx int) {
experiment.MeasureDuration("duration", func() {
// Measured operation
_ = handler.Has("test.txt")
})
}, gmeasure.SamplingConfig{
N: 100,
Duration: time.Second,
NumParallel: 0,
})
stats := experiment.GetStats("duration")
Expect(stats.DurationFor(gmeasure.StatMedian)).To(
BeNumerically("<", 100*time.Microsecond),
)
})
})
```
---
## Best Practices
### Testing Guidelines
#### ✅ DO
```go
// Use descriptive test names
It("should return 404 for non-existent files", func() { ... })
// Use BeforeEach for setup
BeforeEach(func() {
handler = newTestStatic()
})
// Use GinkgoRecover
BeforeEach(func() {
defer GinkgoRecover()
})
// Test edge cases
It("should handle nil configuration", func() { ... })
It("should handle empty paths", func() { ... })
// Verify error conditions
Expect(err).To(HaveOccurred())
Expect(err).To(MatchError(ContainSubstring("expected")))
// Use table-driven tests for variations
DescribeTable("path validation",
func(path string, expected bool) {
result := handler.IsPathSafe(path)
Expect(result).To(Equal(expected))
},
Entry("valid path", "/file.txt", true),
Entry("traversal", "/../etc/passwd", false),
)
```
#### ❌ DON'T
```go
// Don't use hardcoded timeouts
time.Sleep(100 * time.Millisecond) // ❌ Flaky
// Don't ignore errors
_ = handler.SetConfig(config) // ❌
// Don't test implementation details
Expect(handler.(*staticHandler).rlc).NotTo(BeNil()) // ❌
// Don't duplicate test code
// ❌ Copy-paste test setup instead of using helpers
// Don't skip race detector
// ❌ Only run: go test
```
### Coverage Goals
- **Minimum:** 80% overall coverage
- **Critical paths:** 90%+ (security, rate limiting)
- **Error handling:** All error paths tested
- **Edge cases:** Null, empty, invalid inputs

## Troubleshooting
### Common Issues
#### Test Failures
**Problem:** Tests fail intermittently
```bash
# Solution: Run with race detector
CGO_ENABLED=1 go test -race -count=10
```
**Problem:** Coverage report not generated
```bash
# Solution: Ensure correct flags
go test -coverprofile=coverage.out -covermode=atomic
```
#### Race Conditions
**Problem:** Race detector reports data races
```bash
# Solution: Check atomic usage
# All shared state must use atomic operations or locks
```
**Example Fix:**
```go
// ❌ Bad: Direct access
func (s *staticHandler) getConfig() *Config {
return s.config // Race condition!
}
// ✅ Good: Atomic access
func (s *staticHandler) getConfig() *Config {
return s.cfg.Load()
}
```
#### Benchmark Failures
**Problem:** Benchmark results inconsistent
```bash
# Solution: Increase sample size
go test -bench=. -benchtime=10s
```
**Problem:** Memory allocations too high
```bash
# Solution: Profile memory
go test -bench=. -benchmem -memprofile=mem.prof
go tool pprof mem.prof
```
### Debug Tips
```bash
# Verbose test output
go test -v
# Run specific test
go test -v -run TestName
# Show test names without running
go test -list=.
# Increase timeout for slow tests
go test -timeout=30m
# Disable test caching
go test -count=1
# Enable more detailed race detection
GORACE="log_path=race.log halt_on_error=1" CGO_ENABLED=1 go test -race
```

## CI Integration
### GitHub Actions
```yaml
name: Tests
on: [push, pull_request]
jobs:
test:
runs-on: ubuntu-latest
strategy:
matrix:
go-version: ['1.21', '1.22', '1.23']
steps:
- uses: actions/checkout@v3
- name: Set up Go
uses: actions/setup-go@v4
with:
go-version: ${{ matrix.go-version }}
- name: Run tests
run: go test -v -cover -coverprofile=coverage.out ./...
- name: Run race detector
run: CGO_ENABLED=1 go test -race ./...
- name: Upload coverage
uses: codecov/codecov-action@v3
with:
files: ./coverage.out
```
### GitLab CI
```yaml
stages:
- test
- coverage
test:
stage: test
image: golang:1.21
script:
- go test -v ./...
- CGO_ENABLED=1 go test -race ./...

stage: coverage
image: golang:1.21
script:
- go test -cover -coverprofile=coverage.out ./...
- go tool cover -func=coverage.out
artifacts:
paths:
- coverage.out
```
### Pre-commit Hook
```bash
#!/bin/bash
# .git/hooks/pre-commit
echo "Running tests..."
go test ./... || exit 1
echo "Running race detector..."
CGO_ENABLED=1 go test -race ./... || exit 1
echo "Checking coverage..."
COVERAGE=$(go test -cover ./... | grep coverage | awk '{print $5}' | sed 's/%//')
if (( $(echo "$COVERAGE < 80" | bc -l) )); then
echo "Coverage $COVERAGE% is below 80%"
exit 1
fi
echo "All checks passed!"
```
### Makefile Targets
```makefile
.PHONY: test test-race test-cover test-bench
test:
go test -v ./...
test-race:
CGO_ENABLED=1 go test -race -v ./...
test-cover:
go test -cover -coverprofile=coverage.out ./...
go tool cover -html=coverage.out -o coverage.html
test-bench:
go test -bench=. -benchmem ./...
test-all: test test-race test-cover
@echo "All tests passed!"
```

/*
Package static provides a secure, high-performance static file server for Gin framework
with embedded filesystem support, comprehensive security features, and WAF/IDS/EDR integration.
# Overview
The static package is designed to serve files from Go's embed.FS with enterprise-grade
security features including:
- Path traversal protection with configurable rules
- IP-based rate limiting (DoS/scraping prevention)
- Suspicious access pattern detection
- MIME type validation and filtering
- HTTP caching (ETag, Cache-Control)
- Integration with external security systems (WAF/IDS/EDR)
All operations are thread-safe using atomic operations without mutexes for maximum
performance and scalability.
# Architecture
The package follows a layered architecture with clear separation of concerns:

# Security Features
The package implements defense-in-depth with multiple security layers:
## 1. Path Traversal Protection
Protects against directory traversal attacks:
- Detects ".." sequences before path normalization
- Validates against null byte injection
- Enforces maximum path depth
- Blocks access to dot files (.env, .git, etc.)
- Pattern-based blocking (configurable)
Example:
handler.SetPathSecurity(static.PathSecurityConfig{
Enabled: true,
AllowDotFiles: false,
MaxPathDepth: 10,
BlockedPatterns: []string{".git", ".svn", "node_modules"},
})
## 2. Rate Limiting
IP-based rate limiting tracks unique file paths per IP:
- Configurable request limits and time windows
- IP whitelisting support
- Trusted proxy detection
- Automatic cache cleanup
- Thread-safe atomic operations
Example:
handler.SetRateLimit(static.RateLimitConfig{
Enabled: true,
MaxRequests: 100,
Window: time.Minute,
CleanupInterval: 5 * time.Minute,
WhitelistIPs: []string{"127.0.0.1"},
})
## 3. Suspicious Access Detection
Monitors and logs suspicious file access patterns:
- Configuration file access (.env, config.php)
- Backup file enumeration (.bak, .old)
- Admin panel scanning (wp-admin, phpmyadmin)
- Database file requests (.sql, .db)
- Logs both successful and failed attempts
## 4. MIME Type Validation
Controls which file types can be served:
- MIME type detection by file extension
- Whitelist/blacklist configuration
- Custom MIME type mapping
- Blocks dangerous file types (.exe, .sh)
## 5. HTTP Caching
Optimizes bandwidth and performance:
- ETag generation and validation
- Cache-Control headers (public/private)
- 304 Not Modified responses
- Configurable cache duration
- Last-Modified support
# Security Backend Integration
The package can report security events to external systems:
┌──────────────┐ ┌──────────────┐ ┌──────────────┐
│ Static │ │ Security │ │ External │
│ Handler │────────►│ Event │────────►│ System │
│ │ │ Processor │ │ (WAF/IDS) │
└──────────────┘ └──────────────┘ └──────────────┘
│
├─────► Webhook (JSON/CEF)
│
└─────► Go Callbacks
Supported integrations:
- Webhooks with custom headers (Authorization, etc.)
- Common Event Format (CEF) for SIEM systems
- Go callbacks for custom processing
- Batch processing for efficiency
- Configurable severity filtering
# Thread Safety
All data structures use atomic operations without mutexes:
Configuration: libatm.Value[*Config] (atomic.Value wrapper)
IP Tracking: libatm.MapTyped[string, *T] (atomic map)
Counters: atomic.Int64, atomic.Uint64 (standard atomic)
Event Batch: atomic operations only (no mutex)
This design ensures:
- Zero contention under high load
- Predictable performance
- No deadlock risk
- Lock-free scalability
# Performance Considerations
The package is optimized for high-performance scenarios:
1. Atomic Operations: All state managed without mutexes
2. Lazy Initialization: Security features activated only when configured
3. Batch Processing: Multiple events sent together to reduce overhead
4. HTTP Caching: ETag reduces bandwidth and CPU usage
5. Embedded FS: No disk I/O for file access
Typical performance characteristics:
- Request handling: <1ms per request (cached)
- Rate limit check: ~100ns (atomic read)
- Path validation: <10μs (string operations)
- ETag generation: <1μs (hash calculation)
# Dependencies
This package requires:
- github.com/gin-gonic/gin - HTTP framework
- github.com/nabbar/golib/atomic - Thread-safe atomic wrappers
- github.com/nabbar/golib/context - Context-aware configuration
- github.com/nabbar/golib/logger - Logging interface
- github.com/nabbar/golib/errors - Error management
- github.com/nabbar/golib/router - Router helpers
- github.com/nabbar/golib/monitor - Health monitoring
# Example Usage
Basic static file server:
package main
import (
"context"
"embed"
"github.com/gin-gonic/gin"
"github.com/nabbar/golib/static"
)
//go:embed assets/*
var content embed.FS
func main() {
handler := static.New(context.Background(), content, "assets")
router := gin.Default()
handler.RegisterRouter("/static", router.GET)
router.Run(":8080")
}
With security features:
handler := static.New(context.Background(), content, "assets")
// Path security
handler.SetPathSecurity(static.DefaultPathSecurityConfig())
// Rate limiting
handler.SetRateLimit(static.RateLimitConfig{
Enabled: true,
MaxRequests: 100,
Window: time.Minute,
})
// HTTP caching
handler.SetHeaders(static.DefaultHeadersConfig())
// Security backend
handler.SetSecurityBackend(static.SecurityConfig{
Enabled: true,
WebhookURL: "https://waf.example.com/events",
})
See example_test.go for more comprehensive examples.
# Best Practices
1. Always enable path security in production:
handler.SetPathSecurity(static.DefaultPathSecurityConfig())
2. Configure rate limiting appropriate to your traffic:
- API serving: 100-1000 requests/minute
- Public websites: 1000-10000 requests/minute
3. Use HTTP caching to reduce server load:
handler.SetHeaders(static.DefaultHeadersConfig())
4. Monitor security events in production:
handler.SetSecurityBackend() with appropriate webhooks
5. Whitelist known IPs (monitoring, health checks):
config.WhitelistIPs = []string{"monitoring-ip"}
6. Use custom MIME types for modern formats:
config.CustomMimeTypes = map[string]string{".wasm": "application/wasm"}
7. Enable suspicious access logging:
handler.SetSuspicious(static.DefaultSuspiciousConfig())
# Troubleshooting
Common issues and solutions:
403 Forbidden:
- Check path security configuration
- Verify file is not a dot file (if AllowDotFiles = false)
- Check blocked patterns
429 Too Many Requests:
- Increase rate limit (MaxRequests)
- Add IP to whitelist
- Increase time window
404 Not Found:
- Verify file exists in embed.FS
- Check embedRootDir parameter in New()
- Use handler.Has() to verify file presence
# Testing
The package includes comprehensive tests:
- 229+ test cases
- Thread safety verified with race detector
- Concurrency stress tests
- Benchmark tests
- Security scenario tests
Run tests:
go test -v
go test -race (with race detector)
go test -bench . (benchmarks)

// Package static provides a secure, high-performance static file server for Gin framework
// with embedded filesystem support, rate limiting, path security, and WAF/IDS/EDR integration.
//
// This package is designed to serve static files from an embedded filesystem (embed.FS)
// with advanced security features including:
//
// - Path traversal protection
// - IP-based rate limiting
// - Suspicious access detection
// - MIME type validation
// - HTTP caching (ETag, Cache-Control)
// - Integration with WAF/IDS/EDR systems
//
// Thread Safety:
//
// All operations are thread-safe and use atomic operations without mutexes for
// maximum performance and scalability.
//
// Basic Usage:
//
// package main
//
// import (
// "context"
// "embed"
// "github.com/gin-gonic/gin"
// "github.com/nabbar/golib/static"
// )
