-**Pool Cloning and Merging:** - -```go -package main - -import ( - "context" - "github.com/nabbar/golib/httpserver/pool" -) - -func main() { - // Original pool - p1 := pool.New(nil, handler) - // ... add servers ... - - // Clone for different context - ctx2 := context.Background() - p2 := p1.Clone(ctx2) // Independent copy - - // Create another pool - p3 := pool.New(nil, handler) - // ... add different servers ... - - // Merge p3 into p1 - if err := p1.Merge(p3, nil); err != nil { - panic(err) - } - - // p1 now contains servers from both pools -} -``` - -### types Subpackage - -Shared type definitions and constants used across the package. -

It extends the standard library's http.Server with additional features while +// maintaining compatibility with existing http.Handler implementations. +// +// # Design Philosophy +// +// The httpserver package follows these core design principles: +// +// 1. Configuration-Driven Architecture: Servers are defined through declarative configuration +// structures that are validated before use, enabling early detection of configuration errors +// and supporting externalized configuration from files, environment variables, or databases. +// +// 2. Lifecycle Management: Complete control over server start, stop, and restart operations +// with context-aware cancellation and graceful shutdown support. Servers can be started, +// stopped, and restarted programmatically with proper resource cleanup. +// +// 3. Thread-Safe Operations: All operations use atomic values and proper synchronization +// primitives, ensuring safe concurrent access from multiple goroutines without external +// locking requirements. +// +// 4. Production-Ready Features: Built-in monitoring integration, structured logging with +// field context, error handling with typed error codes, port conflict detection, and health +// checking capabilities. +// +// 5. Composable Design: The pool subpackage enables orchestration of multiple server instances +// as a unified entity, supporting filtering, batch operations, and aggregated monitoring. +// +// # Key Features +// +// Complete Lifecycle Control: +// - Context-aware Start, Stop, and Restart operations +// - Automatic resource cleanup and graceful shutdown +// - Uptime tracking and running state queries +// - Error tracking and recovery mechanisms +// +// Configuration Management: +// - Declarative configuration with struct tag validation +// - Deep cloning for safe configuration copies +// - Dynamic configuration updates with SetConfig +// - TLS/HTTPS configuration with certificate management +// +// Handler Management: +// - Dynamic handler registration via function callbacks +// - Multiple named handlers per server instance +// - Handler key-based routing for multi-handler scenarios +// - Fallback BadHandler for misconfigured servers +// +// TLS/HTTPS Support: +// - Integrated certificate management +// - Optional and mandatory TLS modes +// - Default TLS configuration inheritance +// - Automatic TLS detection and configuration +// +// Monitoring and Health Checking: +// - Built-in health check endpoints +// - Integration with monitor package +// - Server metrics and status information +// - Unique monitoring identifiers per server +// +// Pool Management (via pool subpackage): +// - Coordinate multiple server instances +// - Unified start/stop/restart operations +// - Advanced filtering by name, address, or URL +// - Configuration-based pool creation +// +// Thread-Safe Operations: +// - Atomic value storage for handlers and state +// - Concurrent access without explicit locking +// - Safe handler replacement during operation +// - Context-based synchronization +// +// Port Management: +// - Automatic port availability checking +// - Conflict detection before binding +// - Retry logic for port conflicts +// - Support for all interface binding (0.0.0.0) +// +// # Architecture +// +// The package consists of three main components working together: +// +// ┌────────────────────────────────────┐ +// │ Application Layer │ +// │ (HTTP Handlers & Routes) │ +// └─────────────────┬──────────────────┘ +// │ +// ┌─────────▼─────────┐ +// │ httpserver │ +// │ Package API │ +// └─────────┬─────────┘ +// │ +// ┌─────────────┼──────────────┐ +// │ │ │ +// ┌───▼───┐ ┌────▼────┐ ┌───▼────┐ +// │Server │ │ Pool │ │ Types │ +// │ │ │ │ │ │ +// │Config │◄───┤ Manager │ │Handler │ +// │Run │ │ Filter │ │Fields │ +// │Monitor│ │ Clone │ │Const │ +// └───┬───┘ └────┬────┘ └────────┘ +// │ │ +// └──────┬──────┘ +// │ +// ┌──────▼──────┐ +// │ Go stdlib │ +// │ http.Server │ +// └─────────────┘ +// +// Component Responsibilities: +// +// - Server: Core HTTP server implementation with lifecycle management +// - Config: Declarative configuration with validation and cloning +// - Pool: Multi-server orchestration and batch operations +// - Types: Shared type definitions and constants +// - Monitor: Health checking and metrics collection +// - Handler: Dynamic handler registration and management +// +// Data Flow: +// 1.

Handler Replacement During Operation: Handlers can be replaced while the server +// is running, but active requests continue using the previous handler. New requests +// use the updated handler. This may cause inconsistent behavior during handler updates. +// +// 2. TLS Certificate Rotation: Updating TLS certificates requires server restart. +// The SetConfig method does not apply TLS changes to running servers. +// +// 3. Port Binding Limitations: Cannot bind to privileged ports (<1024) without +// appropriate system permissions (CAP_NET_BIND_SERVICE on Linux or root access). +// +// 4. Listen Address Changes: Changing the Listen address via SetConfig requires +// a server restart to take effect. The new address is not applied to running servers. +// +// 5. HTTP/2 Configuration: HTTP/2 settings cannot be changed after server creation +// without recreating the server instance. +// +// 6. Concurrent Stop Calls: Multiple concurrent Stop calls may result in redundant +// shutdown attempts. Use external synchronization if multiple goroutines may call Stop. +// +// 7. Context Cancellation: Server operations respect context cancellation, but +// forcefully cancelled contexts (e.g., exceeded deadline during graceful shutdown) +// may result in abrupt connection termination. +// +// 8. Monitoring Overhead: Each server maintains monitoring state. For deployments +// with hundreds of servers, consider disabling monitoring for non-critical instances. +// +// # Best Practices +// +// DO: +// - Always validate configuration before creating servers +// - Use context.WithTimeout for Stop operations to prevent hanging +// - Register handlers before calling New() when possible +// - Use defer srv.Stop(ctx) to ensure cleanup +// - Check IsRunning() before calling Stop to avoid errors +// - Set appropriate timeouts (ReadTimeout, WriteTimeout, IdleTimeout) +// - Use the pool subpackage for managing multiple servers +// - Monitor server health in production deployments +// - Use unique server names for debugging and monitoring +// +// DON'T: +// - Don't create servers without validating configuration +// - Don't ignore errors from Start, Stop, or SetConfig +// - Don't assume port availability without checking +// - Don't call Stop without context timeout +// - Don't modify Config after passing to New() (use Clone first) +// - Don't rely on handler updates to active connections +// - Don't bind to 0.0.0.0 without considering security implications +// - Don't start servers in goroutines without proper error handling +// +// # Integration with Standard Library +// +// The package integrates seamlessly with Go's standard library: +// +// Standard Library | Integration Point +// -------------------------|------------------------------------------ +// net/http.Server | Wrapped and managed by this package +// net/http.Handler | Compatible with all standard handlers +// context.Context | Used throughout for cancellation +// net.Listener | Managed internally for binding +// crypto/tls | TLS configuration via certificates package +// +// # Related Packages +// +// This package works with other golib packages: +// +// - github.com/nabbar/golib/httpserver/pool: Multi-server orchestration +// - github.com/nabbar/golib/httpserver/types: Shared type definitions +// - github.com/nabbar/golib/certificates: TLS/SSL certificate management +// - github.com/nabbar/golib/monitor: Health checking and metrics +// - github.com/nabbar/golib/logger: Structured logging integration +// - github.com/nabbar/golib/runner: Lifecycle management primitives +// - github.com/nabbar/golib/context: Typed context storage +// +// External Dependencies: +// +// - github.com/go-playground/validator/v10: Configuration validation +// - golang.org/x/net/http2: HTTP/2 support +// +// # Testing +// +// The package includes comprehensive testing using Ginkgo v2 and Gomega: +// +// - Configuration validation tests +// - Server lifecycle tests (start, stop, restart) +// - Handler management tests +// - Monitoring integration tests +// - Concurrency and race detection tests +// - Integration tests with actual HTTP servers +// +// Run tests: +// +// go test -v ./... +// go test -race -v ./... +// go test -cover -v ./... +// +// For detailed testing documentation, see TESTING.md in the package directory. +// +// # Examples +// +// See example_test.go for comprehensive usage examples covering: +// - Basic HTTP server creation and lifecycle +// - HTTPS server with TLS configuration +// - Multiple handlers with handler keys +// - Server pool management +// - Dynamic configuration updates +// - Graceful shutdown patterns +// - Monitoring integration +// - Error handling strategies +package httpserver diff --git a/httpserver/edge_cases_test.go b/httpserver/edge_cases_test.go new file mode 100644 index 0000000..40dffe3 --- /dev/null +++ b/httpserver/edge_cases_test.go @@ -0,0 +1,293 @@ +/* + * MIT License + * + * Copyright (c) 2025 Nicolas JUHEL + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in all + * copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Testing Frameworks + +#### Ginkgo v2 - BDD Testing Framework + +**Why Ginkgo over standard Go testing:** +- ✅ **Hierarchical organization**: `Describe`, `Context`, `It` for clear test structure. +- ✅ **Better readability**: Tests read like specifications. +- ✅ **Rich lifecycle hooks**: `BeforeEach`, `AfterEach` for setup/teardown. +- ✅ **Async testing**: `Eventually`, `Consistently` for concurrent behavior. +- ✅ **Parallel execution**: Built-in support for concurrent test runs. + +#### Gomega - Matcher Library + +**Advantages:** +- ✅ **Expressive matchers**: `Equal`, `BeNumerically`, `HaveOccurred`. +- ✅ **Async assertions**: `Eventually` polls for state changes. + +#### gmeasure - Performance Measurement + +Used for benchmarking throughput and latency within the BDD suite. + +### Testing Concepts & Standards + +#### ISTQB Alignment + +This test suite follows **ISTQB (International Software Testing Qualifications Board)** principles: + +1. **Test Levels** (ISTQB Foundation Level): + * **Unit Testing**: Individual functions (`New`, `StoreNew`, `Load`). + * **Integration Testing**: Component interactions (`Filter`, `Merge`, `Walk`). + * **System Testing**: End-to-end scenarios (Lifecycle, Examples). + +2. **Test Types** (ISTQB Advanced Level): + * **Functional Testing**: Verify behavior meets specifications (Pool management). + * **Non-Functional Testing**: Performance, concurrency, thread safety. + * **Structural Testing**: Code coverage (Branch coverage). + +3. **Test Design Techniques**: + * **Equivalence Partitioning**: Valid configs vs invalid configs. + * **Boundary Value Analysis**: 0 servers, 1 server, multiple servers. + * **State Transition Testing**: Server lifecycle (Stopped <-> Running). + * **Error Guessing**: Concurrent access patterns. + +#### Testing Pyramid + +The suite follows the Testing Pyramid principle: + +``` + /\ + / \ + / E2E\ (System/Lifecycle Tests) + /______\ + / \ + / Integr. \ (Filter/Merge/Walk Tests) +

It enables simultaneous operation of multiple servers with different +// configurations, unified lifecycle control, and advanced filtering capabilities. +// +// # Overview +// +// The pool package extends github.com/nabbar/golib/httpserver by providing a container +// for managing multiple HTTP server instances as a cohesive unit. All servers in the pool +// can be started, stopped, or restarted together while maintaining individual configurations +// and bind addresses. +// +// Key capabilities: +// - Unified lifecycle management (Start/Stop/Restart all servers) +// - Thread-safe concurrent operations with sync.RWMutex +// - Advanced filtering by name, bind address, or expose address +// - Server merging and configuration validation +// - Monitoring integration for all pooled servers +// - Dynamic server addition and removal during operation +// +// # Design Philosophy +// +// 1.

It serves as the shared type system for server configuration, handler registration, field identification, and timeout management across the httpserver ecosystem. + +### Why a Separate Types Package? + +Separating types into their own package provides several architectural benefits: + +**Benefits of Dedicated Types:** +- ✅ **No Circular Dependencies**: Higher-level packages (httpserver, pool) can import types without dependency cycles +- ✅ **Shared Vocabulary**: Consistent type definitions across all HTTP server components +- ✅ **Minimal Import Footprint**: Packages importing types don't pull in heavy dependencies +- ✅ **Interface Stability**: Type definitions remain stable even as implementations evolve +- ✅ **Clear Contracts**: FuncHandler and FieldType define explicit contracts for server operations +- ✅ **Type Safety**: Compile-time guarantees prevent invalid field specifications and handler types + +**Internally**, the types package uses only standard library primitives (`net/http`, `time`), ensuring zero external dependencies. This makes it suitable as a foundation layer that other packages can safely depend on without transitive dependency concerns. + +### Design Philosophy + +1. **Minimal Dependencies**: Depend only on standard library to serve as stable foundation for higher-level packages. +2. **Type Safety First**: Use custom types (`FieldType`) to provide compile-time safety and prevent invalid operations. +3. **Fail-Safe Defaults**: Provide safe fallbacks (`BadHandler`) that fail visibly rather than silently. +4. **Constants Over Magic Values**: Use named constants for all configuration values to improve code readability. +5. **Zero Allocation Types**: Design types for minimal runtime overhead (empty structs, uint8 enums). +6. **Interface Compliance**: Ensure types properly implement standard interfaces (`http.Handler`). + +### Key Features + +- ✅ **Field Type System**: `FieldType` enumeration enables type-safe server filtering by name, bind address, or expose URL. +- ✅ **Handler Registration**: `FuncHandler` defines the contract for dynamic handler registration. +- ✅ **Fallback Handling**: `BadHandler` provides a safe default when no valid handler is configured. +- ✅ **Timeout Management**: Pre-defined timeout constants standardize server lifecycle operations. +- ✅ **Zero Dependencies**: Only depends on standard library `net/http` and `time`. +- ✅ **Minimal Overhead**: Types designed for zero or minimal runtime allocation. + +--- + +## Architecture + +### Component Diagram + +``` +┌────────────────────────────────────────────────────────────┐ +│ httpserver/types │ +├────────────────────────────────────────────────────────────┤ +│ │ +│ ┌──────────────────┐ ┌─────────────────────┐ │ +│ │ Field Types │ │ Handler Types │ │ +│ │ (Enumeration) │ │ (Interfaces) │ │ +│ └──────┬───────────┘ └──────────┬──────────┘ │ +│ │ │ │ +│ ▼ ▼ │ +│ ┌──────────────────┐ ┌─────────────────────┐ │ +│ │ FieldType (uint8)│ │ FuncHandler (func) │ │ +│ ├──────────────────┤ ├─────────────────────┤ │ +│ │ FieldName = 0 │ │ Returns map[string] │ │ +│ │ FieldBind = 1 │ │ http.Handler │ │ +│ │ FieldExpose = 2 │ │ │ │ +│ └──────────────────┘ └─────────────────────┘ │ +│ │ +│ ┌──────────────────┐ ┌─────────────────────┐ │ +│ │ Constants │ │ Default Handler │ │ +│ ├──────────────────┤ ├─────────────────────┤ │ +│ │ HandlerDefault │ │ BadHandler struct{} │ │ +│ │ BadHandlerName │ │ NewBadHandler() │ │ +│ │ TimeoutWaiting* │ │ ServeHTTP() → 500 │ │ +│ └──────────────────┘ └─────────────────────┘ │ +│ │ +└────────────────────────────────────────────────────────────┘ + │ + ▼ + ┌────────────────────────────────────┐ + │ Consuming Packages │ + ├────────────────────────────────────┤ + │ httpserver (server impl) │ + │ httpserver/pool (server registry) │ + │ Application code (configuration) │ + └────────────────────────────────────┘ +``` + +### Data Flow + +1. **Type Definition**: + * Constants are compiled at build time (zero runtime cost). + * `FieldType` values are `uint8` enums (1 byte each). + * `BadHandler` is an empty struct (zero bytes). + +2. **Handler Registration**: + * `FuncHandler` is invoked to retrieve handler map. + * Map keys use `HandlerDefault` constant or custom strings. + * Handlers are registered in server configuration. + +3. **Field Filtering**: + * Server pool queries use `FieldType` for type-safe filtering. + * Switch statements or map keys use enum values. + * Compile-time type checking prevents invalid fields. + +### Limitations + +This package is intentionally minimal with the following design constraints: + +1. **No Dynamic Field Types**: `FieldType` is a closed enumeration (0, 1, 2). Adding new field types requires modifying this package and recompiling consuming packages. + +2. **No Handler Lifecycle Management**: `BadHandler` does not implement graceful shutdown, resource cleanup, or lifecycle hooks. It's a stateless fallback. + +3. **Fixed Timeout Values**: Timeout constants (`TimeoutWaitingStop`, `TimeoutWaitingPortFreeing`) are compile-time constants and cannot be configured at runtime. + +4. **No Validation**: The package does not validate handler maps returned by `FuncHandler`. Validation is the responsibility of consuming packages. + +5. **Single Error Status**: `BadHandler` always returns HTTP 500 Internal Server Error. Custom error codes require implementing a custom `http.Handler`. + +6. **No State Management**: Types are stateless primitives. State management (server instances, handler routing) is handled by consuming packages. + +--- + +## Performance + +### Benchmarks + +Based on type characteristics (Go 1.25, standard library primitives): + +| Operation | Runtime Cost | Memory Cost | +|-----------|--------------|-------------| +| **FieldType Comparison** | 0 ns | 0 bytes | +| **Constant Access** | 0 ns | 0 bytes | +| **BadHandler Creation** | <10 ns | 0 bytes (empty struct) | +| **BadHandler.ServeHTTP** | <100 ns | 0 allocations | +| **FuncHandler Invocation** | Depends on implementation | Depends on map size | + +*Note: FieldType and constants are compile-time values with zero runtime overhead.* + +### Memory Usage + +- **Base Overhead**: Zero (all types are primitives or empty structs). +- **FieldType**: 1 byte per variable (`uint8`). +- **BadHandler**: 0 bytes (empty struct, allocated on stack). +- **Constants**: Compiled into binary, no runtime memory allocation. +- **Optimization**: Types designed for zero-allocation scenarios where possible. + +### Scalability + +- **Type Safety**: Compile-time checks scale to any codebase size. +- **Constant Propagation**: Compiler optimizes constant usage at compile time. +- **Zero Contention**: No shared mutable state, safe for unlimited concurrent use. +- **Handler Maps**: Scalability depends on `FuncHandler` implementation (not managed by this package). + +--- + +## Use Cases + +### 1.

standard Go testing:** +- ✅ **Hierarchical organization**: `Describe`, `Context`, `It` for clear test structure. +- ✅ **Better readability**: Tests read like specifications. +- ✅ **Rich lifecycle hooks**: `BeforeEach`, `AfterEach` for setup/teardown. +- ✅ **Async testing**: `Eventually`, `Consistently` for concurrent behavior. +- ✅ **Parallel execution**: Built-in support for concurrent test runs. + +#### Gomega - Matcher Library + +**Advantages:** +- ✅ **Expressive matchers**: `Equal`, `BeNumerically`, `HaveOccurred`. +- ✅ **Async assertions**: `Eventually` polls for state changes. + +#### gmeasure - Performance Measurement + +Not used in this package (no performance-critical operations requiring benchmarking). + +### Testing Concepts & Standards + +#### ISTQB Alignment + +This test suite follows **ISTQB (International Software Testing Qualifications Board)** principles: + +1. **Test Levels** (ISTQB Foundation Level): + * **Unit Testing**: Individual type definitions and constants. + * **Integration Testing**: Not applicable (no component interactions). + * **System Testing**: Not applicable (types package has no system-level behavior). + +2. **Test Types** (ISTQB Advanced Level): + * **Functional Testing**: Verify type behavior meets specifications (constants, enums). + * **Non-Functional Testing**: Not applicable (no performance concerns for primitives). + * **Structural Testing**: Code coverage (100% statement coverage). + +3. **Test Design Techniques**: + * **Equivalence Partitioning**: Valid enum values vs invalid casts. + * **Boundary Value Analysis**: Enum values (0, 1, 2), timeout durations. + * **State Transition Testing**: Not applicable (stateless types). + * **Error Guessing**: Interface compliance, type assertions. + +#### Testing Pyramid + +The suite follows the Testing Pyramid principle: + +``` + /\ + / \ + / E2E\ (Not applicable - no system) + /______\ + / \ + / Integr. \ (Not applicable - no integration) + /____________\ + / \ + / Unit Tests \ (Type definitions, constants, behavior) +/__________________\ +``` + +### Test Organization + +**File Naming:** +- `*_test.go`: All test files follow this convention +-

It serves as a shared vocabulary for server configuration, +// handler registration, and field identification in server management operations. +// +// The package provides: +// - Field type enumeration for server property filtering +// - Handler registration function signatures +// - Fallback error handlers for misconfigured servers +// - Timeout constants for server lifecycle management +// +// # Design Philosophy +// +// The types package follows these design principles: +// +// 1. Minimal Dependencies: The package depends only on the standard library, +// making it suitable as a foundation for higher-level packages without circular +// dependencies. +// +// 2. Type Safety: Custom types like FieldType provide compile-time safety for +// server filtering operations, preventing invalid field specifications. +// +// 3. Fail-Safe Defaults: The BadHandler provides a safe fallback that always +// returns HTTP 500, ensuring misconfigured servers fail visibly rather than +// silently. +// +// 4. Constants Over Magic Values: Named constants like TimeoutWaitingStop and +// HandlerDefault improve code readability and maintainability. +// +// # Key Features +// +// Field Type System: FieldType enumeration enables type-safe server filtering +// by name, bind address, or expose URL. This is primarily used by the pool +// package for server management. +// +// Handler Registration: FuncHandler defines the contract for dynamic handler +// registration, allowing multiple named handlers per server instance. +// +// Fallback Handling: BadHandler provides a safe default when no valid handler +// is configured, preventing nil pointer panics and providing clear error signals. +// +// Timeout Management: Pre-defined timeout constants standardize server lifecycle +// operations like graceful shutdown and port availability checks. +// +// # Architecture +// +// The package structure is intentionally flat, providing building blocks for +// higher-level abstractions: +// +// ┌────────────────────────────────────────────────────┐ +// │ httpserver/types │ +// ├────────────────────────────────────────────────────┤ +// │ │ +// │ ┌──────────────────┐ ┌──────────────────┐ │ +// │ │ Field Types │ │ Handler Types │ │ +// │ ├──────────────────┤ ├──────────────────┤ │ +// │ │ FieldType │ │ FuncHandler │ │ +// │ │ - FieldName │ │ BadHandler │ │ +// │ │ - FieldBind │ │ NewBadHandler() │ │ +// │ │ - FieldExpose │ │ │ │ +// │ └──────────────────┘ └──────────────────┘ │ +// │ │ +// │ ┌──────────────────┐ ┌──────────────────┐ │ +// │ │ Constants │ │ Handler Keys │ │ +// │ ├──────────────────┤ ├──────────────────┤ │ +// │ │ TimeoutWaiting │ │ HandlerDefault │ │ +// │ │ PortFreeing │ │ BadHandlerName │ │ +// │ │ TimeoutWaiting │ │ │ │ +// │ │ Stop │ │ │ │ +// │ └──────────────────┘ └──────────────────┘ │ +// │ │ +// └────────────────────────────────────────────────────┘ +// │ +// ▼ +// Used by httpserver, httpserver/pool, +// and other HTTP server components +// +// # Usage Patterns +// +// ## Field Type Filtering +// +// FieldType enables type-safe filtering of servers by specific attributes: +// +// switch filterField { +// case types.FieldName: +// // Filter by server name +// case types.FieldBind: +// // Filter by bind address +// case types.FieldExpose: +// // Filter by expose URL +// } +// +// ## Handler Registration +// +// FuncHandler defines how handlers are registered with servers: +// +// handlerFunc := func() map[string]http.Handler { +// return map[string]http.Handler{ +// types.HandlerDefault: myDefaultHandler, +// "api": myAPIHandler, +// "admin": myAdminHandler, +// } +// } +// +// ## Fallback Handler +// +// BadHandler provides safe error handling for misconfigured servers: +// +// handler := types.NewBadHandler() +// // Returns HTTP 500 for all requests +// +// ## Timeout Constants +// +// Standard timeouts for server lifecycle operations: +// +// ctx, cancel := context.WithTimeout(ctx, types.TimeoutWaitingStop) +// defer cancel() +// server.Shutdown(ctx) +// +// # Field Types +// +// FieldType is an enumeration for identifying server properties in filtering +// and listing operations: +// +// FieldName: Server name identifier +// FieldBind: Server listen address (e.g., ":8080", "127.0.0.1:9000") +// FieldExpose: Server public expose URL (e.g., "https://example.com") +// +// These types are primarily used by the pool package to filter and retrieve +// servers based on specific criteria. +// +// # Handler Types +// +// ## FuncHandler +// +// FuncHandler defines the signature for handler registration functions.

No Dynamic Field Types: FieldType is a closed enumeration. Adding new +// field types requires modifying this package. +// +// 2. No Handler Lifecycle Management: BadHandler does not implement graceful +// shutdown or resource cleanup. It's stateless by design. +// +// 3. Fixed Timeout Values: Timeout constants are not configurable at runtime. +// Applications needing custom timeouts should define their own. +// +// 4. No Validation: The package does not validate handler maps returned by +// FuncHandler. Validation is the responsibility of consuming packages. +// +// 5.
