|
||||
- **Memory management**: Efficient data structures and cleanup
|
||||
- **Performance monitoring**: Built-in metrics and recommendations
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Test Files Created:
|
||||
1. **`test_transitive_deps.py`** - Full integration tests
|
||||
2. **`simple_test.py`** - Unit tests for formatting functions
|
||||
3. **`example_usage.py`** - Usage examples and expected responses
|
||||
|
||||
### Test Coverage:
|
||||
- ✅ Direct dependencies (backward compatibility)
|
||||
- ✅ Transitive dependency resolution
|
||||
- ✅ Circular dependency detection
|
||||
- ✅ Edge cases and error handling
|
||||
- ✅ Performance with complex packages
|
||||
|
||||
### Recommended Test Packages:
|
||||
- **Simple**: `six` (no dependencies)
|
||||
- **Moderate**: `requests` (few dependencies)
|
||||
- **Complex**: `django` (moderate dependencies)
|
||||
- **Very Complex**: `tensorflow` (many dependencies)
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### Time Complexity:
|
||||
- **Direct mode**: O(1) API call
|
||||

|
||||
- **Memory usage**: O(n) for package metadata storage
|
||||
- **Network calls**: Cached to reduce redundant requests
|
||||
- **Response size**: Proportional to dependency tree size
|
||||
|
||||
### Optimization Features:
|
||||
- ✅ Visited package caching
|
||||
- ✅ Early termination on cycles
|
||||
- ✅ Configurable depth limits
|
||||
- ✅ Streaming processing
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Basic Usage (Backward Compatible)
|
||||
```python
|
||||
result = await get_package_dependencies("requests")
|
||||
# Returns direct dependencies only
|
||||
```
|
||||
|
||||
### Enable Transitive Analysis
|
||||
```python
|
||||
result = await get_package_dependencies(
|
||||
package_name="requests",
|
||||
include_transitive=True
|
||||
)
|
||||
# Returns complete dependency tree
|
||||
```
|
||||
|
||||
### Advanced Configuration
|
||||
```python
|
||||
result = await get_package_dependencies(
|
||||
package_name="django",
|
||||
include_transitive=True,
|
||||
max_depth=3,
|
||||
python_version="3.11"
|
||||
)
|
||||
# Returns filtered tree for Python 3.11, max 3 levels
|
||||
```
|
||||
|
||||
## Deployment Considerations
|
||||
|
||||
### 1. **Resource Usage**
|
||||
- Monitor memory usage with large dependency trees
|
||||
- Consider rate limiting for resource-intensive requests
|
||||
- Set appropriate max_depth defaults based on infrastructure
|
||||
|
||||
### 2. **API Rate Limits**
|
||||
- Transitive analysis may increase PyPI API usage
|
||||
- Existing caching helps mitigate repeated requests
|
||||
- Consider request queuing for high-volume usage
|
||||
|
||||
### 3. **Response Size**
|
||||
- Large dependency trees produce large responses
|
||||
- Consider response compression for network efficiency
|
||||
- Implement pagination for very large trees if needed
|
||||
|
||||

# Transitive Dependency Enhancement
|
||||
|
||||
## Overview
|
||||
|
||||
This enhancement adds comprehensive transitive dependency analysis to the PyPI Query MCP Server. The `get_package_dependencies` tool now supports analyzing the complete dependency tree of a package with advanced features for handling complex dependency scenarios.
|
||||
|
||||
## New Features
|
||||
|
||||
### 1. Transitive Dependency Resolution
|
||||
- **Parameter**: `include_transitive: bool = False`
|
||||
- **Description**: When set to `True`, recursively resolves all dependencies of dependencies
|
||||
- **Default**: `False` (maintains backward compatibility)
|
||||
|
||||
### 2. Depth Control
|
||||
- **Parameter**: `max_depth: int = 5`
|
||||
- **Description**: Limits the maximum recursion depth to prevent excessive analysis
|
||||
- **Default**: 5 levels deep
|
||||
|
||||
### 3. Python Version Filtering
|
||||
- **Parameter**: `python_version: str | None = None`
|
||||
- **Description**: Filters dependencies based on target Python version compatibility
|
||||
- **Example**: `"3.10"`, `"3.11"`
|
||||
|
||||
## Enhanced Response Format

||||
|
||||
### Transitive Dependencies with Default Settings
|
||||
```python
|
||||
# MCP tool call
|
||||
result = await get_package_dependencies(
|
||||
package_name="requests",
|
||||
include_transitive=True
|
||||
)
|
||||
# Returns complete dependency tree with default depth=5
|
||||
```
|
||||
|
||||
### Advanced Transitive Analysis
|
||||
```python
|
||||
# MCP tool call
|
||||
result = await get_package_dependencies(
|
||||
package_name="django",
|
||||
include_transitive=True,
|
||||
max_depth=3,
|
||||
python_version="3.11"
|
||||
)
|
||||
# Returns filtered dependency tree for Python 3.11 with max depth 3
|
||||
```
|
||||
|
||||
### Testing with Complex Packages
|
||||
```python
|
||||
# Test with packages known for complex dependencies
|
||||
packages_to_test = [
|
||||
"tensorflow", # Machine learning - many dependencies
|
||||
"django", # Web framework - moderate complexity
|
||||
"requests", # HTTP library - simple but popular
|
||||
"fastapi", # Modern web framework
|
||||
"pandas", # Data analysis - scientific dependencies
|
||||
]
|
||||
|
||||
for package in packages_to_test:
|
||||
result = await get_package_dependencies(
|
||||
package_name=package,
|
||||
include_transitive=True,

|
||||
### 4. Depth Limits
|
||||
- **Automatic limiting**: Respects max_depth parameter
|
||||
- **Performance protection**: Prevents excessive API calls
|
||||
- **Progress tracking**: Depth information in results
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### 1. API Usage
|
||||
- **Caching**: Reduces redundant PyPI API calls
|
||||
- **Batch processing**: Efficient handling of multiple dependencies
|
||||
- **Rate limiting**: Respects PyPI rate limits
|
||||
|
||||
### 2. Memory Usage
|
||||
- **Streaming processing**: Processes dependencies as they're resolved
|
||||
- **Memory-efficient data structures**: Optimized for large dependency trees
|
||||
- **Garbage collection**: Proper cleanup of intermediate data
|
||||
|
||||
### 3. Time Complexity
|
||||
- **Exponential growth**: Dependency trees can grow exponentially
|
||||
- **Depth limits**: max_depth prevents runaway analysis
|
||||
- **Early termination**: Stops on circular dependencies
|
||||
|
||||
## Testing Recommendations
|
||||
|
||||
### 1. Test with Various Package Types
|
||||
```python
|
||||
test_cases = [
|
||||
{"package": "six", "expected_complexity": "low"}, # Simple, no deps
|
||||
{"package": "requests", "expected_complexity": "low"}, # Few deps
|
||||
{"package": "django", "expected_complexity": "moderate"}, # Moderate deps
|
||||
{"package": "tensorflow", "expected_complexity": "high"}, # Many deps
|
||||
]
|
||||
```
|
||||
|
||||
### 2. Test Edge Cases
|
||||
- Packages with circular dependencies
|
||||
- Packages with very deep dependency trees
|
||||
- Packages with conflicting version constraints
|
||||
- Packages with optional dependencies
|
||||
|
||||
### 3. Performance Testing
|
||||
- Measure response times for different max_depth values
|
||||
- Test memory usage with large dependency trees
|
||||
- Validate timeout handling
|
||||
|
||||
## Integration Notes
|
||||
|
||||
### 1. Backward Compatibility
|
||||
- Default `include_transitive=False` maintains existing behavior
|
||||
- All existing response fields preserved
|
||||
- No breaking changes to existing functionality
|
||||
|
||||
### 2. MCP Tool Interface
|
||||
The enhanced tool maintains the same interface pattern:
|
||||
```json
|
||||
{
|
||||
"name": "get_package_dependencies",
|
||||
"parameters": {
|
||||
"package_name": "string (required)",
|
||||
"version": "string (optional)",
|
||||
"include_transitive": "boolean (optional, default: false)",
|
||||
"max_depth": "integer (optional, default: 5)",
|
||||
"python_version": "string (optional)"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Logging
|
||||
Enhanced logging provides insights into:
|
||||
- Dependency resolution progress
|
||||
- Performance metrics
|
||||
- Error conditions
|
||||
- Cache hit/miss ratios
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Potential improvements for future versions:
|
||||
1. **Dependency conflict resolution**: Automatic suggestion of compatible versions
|
||||
2. **Security vulnerability scanning**: Integration with security databases
|
||||
3. **License compatibility checking**: Analysis of license conflicts
|
||||
4. **Performance benchmarking**: Real-world performance data
|
||||
5. **Visual dependency graphs**: Export to graph formats
|
||||
6. **Dependency update planning**: Automated update recommendations
|
||||
|
||||
## Conclusion
|
||||
|
||||
The transitive dependency enhancement provides comprehensive dependency analysis while maintaining backward compatibility and performance. It enables users to understand the full impact of package dependencies, identify potential issues, and make informed decisions about package usage.
