Subject: [PATCH 1/6] feat: Add comprehensive web dashboard for Hammerwork job
 queue monitoring
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement a complete web-based admin dashboard as a separate optional crate
to provide real-time monitoring and management of Hammerwork job queues.

## New Features

### Web Dashboard (hammerwork-web crate)
- **Separate optional crate** for easy installation and deployment
- **Modern responsive UI** with HTML5, CSS3, and vanilla JavaScript
- **Real-time monitoring** with WebSocket support for live updates
- **Complete job management** with create, view, retry, and delete operations
- **Queue statistics** with visual charts and metrics
- **Multi-database support** for both PostgreSQL and MySQL backends

### Core Components
- **REST API endpoints** for all job and queue operations
- **WebSocket server** for real-time dashboard updates
- **Authentication system** with basic auth and rate limiting
- **Configuration management** with TOML file support
- **CLI interface** with comprehensive command-line options

### Dashboard Features
- **System overview** with key metrics and health status
- **Interactive charts** using Chart.js for throughput and queue status
- **Job search and filtering** with pagination support
- **Queue management** with clear, pause, and resume operations
- **Real-time updates** via WebSocket connections
- **Responsive design** that works on desktop and mobile devices

### API Endpoints
- `/api/queues` - Queue listing and management
- `/api/jobs` - Job operations (list, create, retry, delete)
- `/api/stats` - System statistics and monitoring data
- `/api/system` - System information and maintenance
- `/health` - Health check endpoint
- `/ws` - WebSocket endpoint for real-time updates

### Technical Implementation
- **Warp web framework** for HTTP server and routing
- **Database abstraction** supporting both PostgreSQL and MySQL
- **Type-safe API** with comprehensive error handling
- **Modular architecture** with clear separation of concerns
- **Production-ready** with proper logging and monitoring

## Usage

```bash
# Install the web dashboard
cargo install --path hammerwork-web --features postgres

# Run the dashboard
hammerwork-web --database-url postgresql://localhost/hammerwork --bind 0.0.0.0 --port 8080

# Or with configuration file
hammerwork-web --config dashboard.toml
```

## Breaking Changes
None - this is a purely additive feature in a separate crate.

## Documentation
- Comprehensive CLI help and usage examples
- Configuration file documentation
- API endpoint specifications
- WebSocket message protocol

+//! # Hammerwork Web Dashboard
+//!
+//! A web-based admin dashboard for monitoring and managing Hammerwork job queues.
+//!
+//! This crate provides a comprehensive web interface for:
+//! - Real-time queue monitoring and statistics
+//! - Job management (retry, cancel, inspect)
+//! - Worker status and utilization
+//! - Dead job analysis and bulk operations
+//! - System health monitoring
+//!
+//! ## Usage
+//!
+//! ### As a Binary
+//!
+//! ```bash
+//! # Install the web dashboard
+//! cargo install hammerwork-web --features postgres
+//!
+//! # Start the dashboard
+//! hammerwork-web --database-url postgresql://localhost/hammerwork --bind 0.0.0.0:8080
+//! ```
+//!
+//! ### As a Library
+//!
+//! ```rust,no_run
+//! use hammerwork_web::{WebDashboard, DashboardConfig};
+//!
+//! #[tokio::main]
+//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
+//!     let config = DashboardConfig {
+//!         bind_address: "127.0.0.1".to_string(),

+//!         database_url: "postgresql://localhost/hammerwork".to_string(),
+//!         ..Default::default()
+//!     };
+//!
+//!     let dashboard = WebDashboard::new(config).await?;
+//!     dashboard.start().await?;
+//!
+//!     Ok(())

Subject: [PATCH 2/6] feat: Enhance hammerwork-web documentation and fix clippy
 warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit encompasses comprehensive improvements across the Hammerwork workspace:

## Web Dashboard Documentation Enhancements
- Add comprehensive doctests to all hammerwork-web modules for improved docs.rs experience
- Document REST API endpoints with practical usage examples
- Add configuration examples using builder patterns
- Include authentication, WebSocket, and server setup examples
- Create CHANGELOG.md and README.md for hammerwork-web crate

## Clippy Warning Fixes
- Fix collapsible if statements in workflow.rs
- Replace and_then with map for ResultStorage parsing
- Remove shadowing to_string methods in tracing.rs
- Use derive(Default) instead of manual implementations
- Rename confusing from_str methods to parse_from_db
- Fix redundant pattern matching across multiple modules
- Handle unused variables properly

## Technical Improvements
- Add base64 dependency for authentication credential parsing
- Fix type system conflicts with multiple database features
- Improve conditional compilation for PostgreSQL/MySQL support
- Add Serialize trait to CreateJobRequest for doctest compatibility

## Documentation Coverage
- 40 comprehensive doctests covering all major components

 This roadmap outlines planned features for Hammerwork, prioritized by impact level and implementation complexity. Features are organized into phases based on their value proposition to users and estimated development effort.
 
-## Phase 1: High Impact, Medium-High Complexity
-*Features that provide significant value but require more substantial implementation effort*
-
-### 🌐 Admin Dashboard & CLI Tools
-**Impact: High** | **Complexity: Medium-High** | **Priority: Medium**
-
-Critical for operational management and developer productivity.
-
-**✅ CLI Tools - COMPLETED v1.1.0+**
-The `cargo-hammerwork` CLI provides comprehensive job queue management:
-- Database migrations and setup
-- Job management (enqueue, list, retry, cancel, inspect)
-- Queue operations (list, clear, statistics)
-- Worker management and monitoring
-- Batch operations and cron scheduling
-- Workflow visualization and dependency management
-- Real-time monitoring and health checks
-
-```bash
-# Available CLI commands
-cargo hammerwork migration run
-cargo hammerwork job list --queue email
-cargo hammerwork queue stats
-cargo hammerwork worker start --queue default
-cargo hammerwork monitor dashboard
-```
-
-**🚧 Web Dashboard - REMAINING**
-Web-based admin interface for visual queue management:
-
-```rust
-// Future web-based admin interface
-let admin_server = AdminServer::new()
-    .with_queue_monitoring()
-    .with_job_management()
-    .with_worker_controls()
-    .bind("127.0.0.1:8080");
-```
-
 ## Phase 2: Medium Impact, Variable Complexity
 *Valuable features for specific use cases or operational efficiency*

+
+## Library Usage
+
+Add to your `Cargo.toml`:
+
+```toml
+[dependencies]
+hammerwork-web = { version = "1.2", features = ["postgres"] }
+# or for MySQL:
+# hammerwork-web = { version = "1.2", features = ["mysql"] }
+```
+
+### Programmatic Usage
+
+```rust
+use hammerwork_web::{WebDashboard, DashboardConfig};
+use std::time::Duration;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let config = DashboardConfig {
+        bind_address: "127.0.0.1".to_string(),
+        port: 8080,
+        database_url: "postgresql://localhost/hammerwork".to_string(),
+        pool_size: 5,
+        static_dir: "./assets".into(),
+        enable_cors: true,
+        request_timeout: Duration::from_secs(30),
+        ..Default::default()
+    };
+
+    let dashboard = WebDashboard::new(config).await?;
+    dashboard.start().await?;
+
+    Ok(())
+}
+```
+
+### With Authentication
+
+```rust
+use hammerwork_web::{WebDashboard, DashboardConfig, AuthConfig};
+
+let config = DashboardConfig::new()
+    .with_database_url("postgresql://localhost/hammerwork")
+    .with_bind_address("0.0.0.0", 8080)
+    .with_auth("admin", "$2b$12$hash...") // bcrypt hash
+    .with_cors(true);
+
+let dashboard = WebDashboard::new(config).await?;
+dashboard.start().await?;
+```
+
+## API Reference
+
+The dashboard exposes a complete REST API:
+
+### Authentication
+
+All API endpoints (except `/health`) require authentication when enabled:
+
+```bash
+curl -u admin:password http://localhost:8080/api/stats/overview
+```
+
+### Endpoints
+
+#### System
+- `GET /health` - Health check (no auth required)
+- `GET /api/stats/overview` - System overview statistics
+- `GET /api/stats/throughput?period=24h` - Throughput data
+
+#### Queues
+- `GET /api/queues` - List all queues with statistics
+- `POST /api/queues/{name}/clear` - Clear all jobs from queue
+- `POST /api/queues/{name}/pause` - Pause queue processing
+- `POST /api/queues/{name}/resume` - Resume queue processing
+
+#### Jobs
+- `GET /api/jobs?status=failed&limit=50` - List jobs with filters
+- `GET /api/jobs/{id}` - Get job details
+- `POST /api/jobs` - Create new job
+- `POST /api/jobs/{id}/retry` - Retry failed job
+- `DELETE /api/jobs/{id}` - Delete job
+
+### WebSocket API
+
+Connect to `ws://localhost:8080/ws` for real-time updates:
+
+```javascript
+const ws = new WebSocket('ws://localhost:8080/ws');
+
+// Subscribe to events
+ws.send(JSON.stringify({
+    type: 'Subscribe',
+    event_types: ['queue_updates', 'job_updates', 'system_alerts']
+}));
+
+// Handle updates
+ws.onmessage = (event) => {
+    const message = JSON.parse(event.data);
+    console.log('Received:', message);
+};
+```
+
+## Development
+
+### Prerequisites
+
+- Rust 1.70+
+- PostgreSQL or MySQL database
+- Node.js (for frontend development)
+
+### Database Setup
+
+Use the provided scripts to set up test databases:
+
+```bash
+# Set up both PostgreSQL and MySQL test databases
+./scripts/setup-test-databases.sh both
+
+# PostgreSQL only
+./scripts/setup-test-databases.sh postgres
+
+# MySQL only  
+./scripts/setup-test-databases.sh mysql
+```
+
+Default test database connections:
+- **PostgreSQL**: `postgresql://postgres:hammerwork@localhost:5433/hammerwork`
+- **MySQL**: `mysql://root:hammerwork@localhost:3307/hammerwork`
+
+### Building
+
+```bash
+# Build with PostgreSQL support
+cargo build --features postgres
+
+# Build with MySQL support
+cargo build --features mysql
+
+# Build with authentication support
+cargo build --features "postgres,auth"
+
+# Build everything
+cargo build --all-features
+```
+
+### Testing
+
+```bash
+# Unit tests
+cargo test
+
+# Integration tests (requires database)
+cargo test --features postgres -- --ignored
+
+# Test with both databases
+./scripts/setup-test-databases.sh test
+```
+
+### Development Commands
+
+```bash
+# Format code
+cargo fmt
+
+# Lint code
+cargo clippy --all-features -- -D warnings
+
+# Run with hot reload (requires cargo-watch)
+cargo watch -x "run --features postgres -- --database-url postgresql://postgres:hammerwork@localhost:5433/hammerwork"
+
+# Generate documentation
+cargo doc --all-features --open
+```
+
+## Frontend Development
+
+The dashboard frontend is built with vanilla JavaScript, HTML, and CSS for minimal dependencies and fast loading.
+
+### Asset Structure
+
+```
+assets/
+├── index.html          # Main dashboard page
+├── dashboard.css       # Styles and responsive design
+├── dashboard.js        # WebSocket client and UI logic
+└── chart.min.js        # Chart.js for data visualization
+```
+
+### Adding Features
+
+1. **New API Endpoint**: Add to appropriate module in `src/api/`
+2. **WebSocket Message**: Update `ServerMessage` enum in `src/websocket.rs`
+3. **Frontend Component**: Add to `assets/dashboard.js` and update UI in `index.html`
+4. **Tests**: Add unit tests in module and integration tests in `tests/`
+
+## Security
+
+### Authentication
+
+- **Basic Authentication**: RFC 7617 compliant with base64 encoding
+- **Password Hashing**: bcrypt with configurable cost (default: 12)
+- **Rate Limiting**: Failed login attempt tracking with account lockout
+- **Session Management**: Configurable session timeouts
+
+### Best Practices
+
+- Change default credentials immediately
+- Use strong passwords (12+ characters)
+- Enable authentication in production
+- Use HTTPS in production
+- Configure firewall rules appropriately
+- Store password hashes securely
+- Regular security updates
+
+### Example: Generate Password Hash
+
+```bash
+# Using bcrypt command-line tool
+echo -n "your-password" | bcrypt-tool hash
+
+# Or in Rust
+use bcrypt::{hash, DEFAULT_COST};
+let hash = hash("your-password", DEFAULT_COST)?;
+```
+
+## Deployment
+
+### Docker
+
+```dockerfile
+FROM rust:1.70 as builder
+WORKDIR /app
+COPY . .
+RUN cargo build --release --features postgres
+
+FROM debian:booksworm-slim

+WORKDIR /app
+EXPOSE 8080
+CMD ["hammerwork-web", "--bind", "0.0.0.0", "--port", "8080"]
+```
+
+### systemd Service
+
+```ini
+[Unit]
+Description=Hammerwork Web Dashboard
+After=network.target postgresql.service
+
+[Service]
+Type=simple
+User=hammerwork

+```
+
+### Nginx Reverse Proxy
+
+```nginx
+server {
+    listen 80;
+    server_name hammerwork.example.com;
+    
+    location / {
+        proxy_pass http://127.0.0.1:8080;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_cache_bypass $http_upgrade;
+    }
+}
+```
+
+## Performance
+
+### Optimization Tips
+
+- **Connection Pooling**: Tune `pool_size` based on concurrent users
+- **WebSocket Limits**: Configure `max_connections` for your use case  
+- **Request Timeouts**: Set appropriate `request_timeout` for your network
+- **Database Indexes**: Ensure proper indexes on hammerwork_jobs table
+- **Static Assets**: Use a CDN for production deployments
+- **Monitoring**: Enable structured logging and metrics collection
+
+### Monitoring
+
+```bash
+# Enable debug logging
+RUST_LOG=hammerwork_web=debug hammerwork-web --config dashboard.toml
+
+# Monitor WebSocket connections
+curl http://localhost:8080/api/stats/overview | jq '.websocket_connections'
+
+# Database connection health
+curl http://localhost:8080/health
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**Database Connection Failed**
+```
+Error: Database connection failed
+```
+- Verify database URL format and credentials
+- Check database server is running and accessible
+- Ensure database exists and migrations are applied
+
+**Static Assets Not Found**
+```
+Error: Static file not found
+```
+- Check `static_dir` path in configuration
+- Ensure assets directory contains `index.html`
+- Verify file permissions
+
+**Authentication Issues**
+```
+401 Unauthorized
+```
+- Verify username and password
+- Check password hash format (bcrypt)
+- Review rate limiting settings
+
+**WebSocket Connection Failed**
+```
+WebSocket connection closed unexpectedly
+```
+- Check firewall settings for WebSocket traffic
+- Verify proxy configuration for Upgrade headers
+- Review browser console for detailed errors
+
+### Debug Mode
+
+```bash
+# Enable verbose logging
+RUST_LOG=debug hammerwork-web --config dashboard.toml
+
+# Enable specific module logging
+RUST_LOG=hammerwork_web::websocket=trace hammerwork-web --config dashboard.toml
+```

 //! Job management API endpoints.
+//!
+//! This module provides comprehensive REST API endpoints for managing Hammerwork jobs,
+//! including creating, listing, searching, and performing actions on jobs.
+//!
+//! # API Endpoints
+//!
+//! - `GET /api/jobs` - List jobs with filtering, pagination, and sorting
+//! - `POST /api/jobs` - Create a new job
+//! - `GET /api/jobs/{id}` - Get details of a specific job
+//! - `POST /api/jobs/{id}/actions` - Perform actions on a job (retry, cancel, delete)
+//! - `POST /api/jobs/bulk` - Perform bulk actions on multiple jobs
+//! - `POST /api/jobs/search` - Search jobs with full-text queries
+//!
+//! # Examples
+//!
+//! ## Creating a Job
+//!
+//! ```rust
+//! use hammerwork_web::api::jobs::CreateJobRequest;
+//! use serde_json::json;

 //! WebSocket implementation for real-time dashboard updates.
+//!
+//! This module provides WebSocket functionality for real-time communication between
+//! the dashboard frontend and backend. It supports connection management, message
+//! broadcasting, and automatic ping/pong for connection health.
+//!
+//! # Message Types
+//!
+//! The WebSocket API supports several message types for different events:
+//!
+//! ```rust
+//! use hammerwork_web::websocket::{ClientMessage, ServerMessage, AlertSeverity};
+//! use serde_json::json;
+//!
+//! // Client messages (sent from browser to server)
+//! let subscribe_msg = ClientMessage::Subscribe {
+//!     event_types: vec!["queue_updates".to_string(), "job_updates".to_string()],
+//! };
+//!
+//! let ping_msg = ClientMessage::Ping;
+//!
+//! // Server messages (sent from server to browser)
+//! let alert_msg = ServerMessage::SystemAlert {
+//!     message: "High error rate detected".to_string(),
+//!     severity: AlertSeverity::Warning,
+//! };
+//!
+//! let pong_msg = ServerMessage::Pong;
+//! ```
+//!
+//! # Connection Management
+//!
+//! ```rust
+//! use hammerwork_web::websocket::WebSocketState;
+//! use hammerwork_web::config::WebSocketConfig;
+//!
+//! let config = WebSocketConfig::default();
+//! let ws_state = WebSocketState::new(config);

Fix MySQL dequeue query field completeness issues and test infrastructure improvements.

- Fixed MySQL ColumnNotFound("trace_id") errors by adding missing tracing fields to dequeue queries
- Updated MySQL dequeue() and dequeue_with_priority_weights() to SELECT all 34 required JobRow fields
- Improved test isolation and fixed race conditions in result storage tests
- Fixed 6 failing doctests in worker.rs with proper async/await usage
- All tests now passing: 228 unit tests, 135 doctests, 0 failures

+## [1.2.1] - 2025-06-30
+
+### Fixed
+- **🐛 MySQL Query Field Completeness**
+  - Fixed `Database(ColumnNotFound("trace_id"))` errors in MySQL dequeue operations
+  - Updated MySQL `dequeue()` and `dequeue_with_priority_weights()` queries to include all tracing fields: `trace_id`, `correlation_id`, `parent_span_id`, `span_context`
+  - Ensures JobRow struct mapping works correctly with all database schema fields added in migration 009_add_tracing.mysql.sql
+  - Fixed two failing tests: `test_mysql_dequeue_includes_all_fields` and `test_mysql_dequeue_with_priority_weights_includes_all_fields`
+
+### Enhanced
+- **🧪 Test Infrastructure Improvements** 
+  - Improved test isolation using unique queue names to prevent test interference
+  - Fixed race conditions in result storage tests by implementing proper job completion polling
+  - Enhanced test database setup to use migration-based approach ensuring schema consistency
+  - Fixed 6 failing doctests in worker.rs by correcting async/await usage in documentation examples
+
+### Technical Implementation
+- MySQL dequeue queries now SELECT all 34 fields required by JobRow struct mapping
+- Complete field list includes: id, queue_name, payload, status, priority, attempts, max_attempts, timeout_seconds, created_at, scheduled_at, started_at, completed_at, failed_at, timed_out_at, error_message, cron_schedule, next_run_at, recurring, timezone, batch_id, result_data, result_stored_at, result_expires_at, result_storage_type, result_ttl_seconds, result_max_size_bytes, depends_on, dependents, dependency_status, workflow_id, workflow_name, trace_id, correlation_id, parent_span_id, span_context
+- All tests now passing: 228 unit tests, 135 doctests, 0 failures
