## 🔧 Technical Achievements
### 1. **Unified Handler Architecture**
```python
# Before: Duplicated code in XMLRPC and JSONRPC handlers
class XMLRPCHandler:
def __init__(self, config):
# 100+ lines of duplicated initialization
# Duplicated SSL configuration
# Duplicated authentication logic
# Duplicated error handling
# After: Clean inheritance with shared functionality
class XMLRPCHandler(BaseOdooHandler):
def __init__(self, config):
super().__init__(config) # Shared initialization
self._create_proxies() # Protocol-specific setup
```
### 2. **Factory Pattern Implementation**
```python
# Before: Manual handler creation
if protocol == "xmlrpc":
handler = XMLRPCHandler(config)
elif protocol == "jsonrpc":
handler = JSONRPCHandler(config)
# After: Factory pattern
handler = HandlerFactory.create_handler(protocol, config)
```
### 3. **Enhanced Error Handling**
```python
# Before: Generic error handling
try:
result = some_operation()
except Exception as e:
logger.error(f"Error: {e}")
# After: Specific error types with context
try:
result = some_operation()
except httpx.HTTPStatusError as e:
raise NetworkError(f"HTTP {e.response.status_code}: {e.response.text}")
except OdooValidationError as e:
raise ValidationError(f"Validation failed: {e.message}")
```
### 4. **Comprehensive Testing**
```python
# 36 comprehensive tests covering:
- Handler Factory functionality
- Base handler features
- XMLRPC handler implementation
- JSONRPC handler implementation
- Connection pool management
