# Version Control System
|
||||
|
||||
## Overview
|
||||
A comprehensive version control system for Django models that provides branching, merging, and change tracking capabilities with optimized performance through batch processing and caching.
|
||||
|
||||
## Requirements
|
||||
|
||||
### System Requirements
|
||||
- Python 3.8+
|
||||
- Django 4.0+
|
||||
- Redis 6.0+ (for caching)
|
||||
- PostgreSQL 12+ (recommended for database)
|
||||
|
||||
### Python Dependencies
|
||||
```
|
||||
django-simple-history>=3.0.0
|
||||
redis>=4.0.0
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
1. Add 'history_tracking' to your INSTALLED_APPS:
|
||||
```python
|
||||
INSTALLED_APPS = [
|
||||
...
|
||||
'history_tracking',
|
||||
]
|
||||
```
|
||||
|
||||
2. Configure Redis connection in settings.py:
|
||||
```python
|
||||
# Uses existing Redis configuration if available
|
||||
CACHES = {
|
||||
"default": {
|
||||
"BACKEND": "django.core.cache.backends.redis.RedisCache",
|
||||
"LOCATION": "redis://127.0.0.1:6379/1", # Adjust as needed
|
||||
}
|
||||
}
|
||||
|
||||
# Version control specific settings
|
||||
VERSION_CONTROL = {
|
||||
'CACHE_PREFIX': 'vc_', # Prefix for cache keys
|
||||
'BATCH_SIZE': 100, # Default batch size for operations
|
||||
'MAX_WORKERS': 4, # Maximum parallel workers
|
||||
'CACHE_DURATIONS': { # Cache durations in seconds
|
||||
'BRANCH': 3600, # 1 hour
|
||||
'CHANGE': 1800, # 30 minutes
|
||||
'HISTORY': 86400, # 24 hours
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
3. Run migrations:
|
||||
```bash
|
||||
python manage.py migrate history_tracking
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Making Models Version-Controlled
|
||||
|
||||
1. Inherit from HistoricalModel:
|
||||
```python
|
||||
from history_tracking.models import HistoricalModel
|
||||
|
||||
class YourModel(HistoricalModel):
|
||||
name = models.CharField(max_length=255)
|
||||
description = models.TextField()
|
||||
```
|
||||
|
||||
2. The model will automatically track:
|
||||
- All field changes
|
||||
- Who made changes
|
||||
- When changes were made
|
||||
- Which branch changes were made in
|
||||
|
||||
### Working with Branches
|
||||
|
||||
```python
|
||||
from history_tracking.models import VersionBranch
|
||||
|
||||
# Create a new branch
|
||||
branch = VersionBranch.objects.create(
|
||||
name="feature/new-content",
|
||||
metadata={"type": "feature"}
|
||||
)
|
||||
|
||||
# Make changes in branch context
|
||||
from history_tracking.context_processors import branch_context
|
||||
|
||||
with branch_context(branch):
|
||||
your_model.save() # Changes are tracked in the branch
|
||||
```
|
||||
|
||||
### Batch Operations
|
||||
|
||||
For handling multiple changes efficiently:
|
||||
|
||||
```python
|
||||
from history_tracking.batch import BatchOperation
|
||||
|
||||
# Create batch operation
|
||||
batch = BatchOperation(max_workers=4)
|
||||
|
||||
# Add changes to batch
|
||||
for item in items:
|
||||
batch.add_change(item, {'field': 'new_value'})
|
||||
|
||||
# Process changes (parallel or sequential)
|
||||
results = batch.commit(parallel=True)
|
||||
```
|
||||
|
||||
### Using the Queue System
|
||||
|
||||
For large-scale operations:
|
||||
|
||||
```python
|
||||
from history_tracking.batch import VersionControlQueue
|
||||
|
||||
# Create queue with custom batch size
|
||||
queue = VersionControlQueue(batch_size=100)
|
||||
|
||||
# Queue changes
|
||||
for item in large_dataset:
|
||||
queue.queue_change(item, {'field': 'new_value'})
|
||||
|
||||
# Process queue
|
||||
results = queue.process_queue(parallel=True)
|
||||
```
|
||||
|
||||
## Cache Management
|
||||
|
||||
The system automatically caches:
|
||||
- Branch information
|
||||
- Change details
|
||||
- Version history
|
||||
|
||||
Cache invalidation is handled automatically, but you can manually invalidate:
|
||||
|
||||
```python
|
||||
from history_tracking.caching import VersionHistoryCache
|
||||
|
||||
# Invalidate specific caches
|
||||
VersionHistoryCache.invalidate_branch(branch_id)
|
||||
VersionHistoryCache.invalidate_history(content_type_id, object_id)
|
||||
|
||||
# Invalidate all version control caches
|
||||
VersionHistoryCache.invalidate_all()
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
The system includes built-in monitoring:
|
||||
|
||||
```python
|
||||
from history_tracking.monitoring import VersionControlMetrics
|
||||
|
||||
# Collect system metrics
|
||||
VersionControlMetrics.collect_system_metrics()
|
||||
VersionControlMetrics.collect_performance_metrics()
|
||||
```
|
||||
|
||||
Metrics are logged and can be viewed:
|
||||
- In application logs
|
||||
- Through the Django admin interface
|
||||
- Via monitoring endpoints (if configured)
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
The system is optimized for:
|
||||
- Batch processing of changes
|
||||
- Efficient caching of frequently accessed data
|
||||
- Parallel processing capabilities
|
||||
- Minimal database queries
|
||||
|
||||
For large-scale operations:
|
||||
- Use batch processing
|
||||
- Enable parallel processing when appropriate
|
||||
- Configure cache durations based on your needs
|
||||
- Monitor performance metrics
|
||||
|
||||
## Security
|
||||
|
||||
The system integrates with Django's authentication and permissions:
|
||||
- All changes are tracked with user information
|
||||
- Branch access can be controlled
|
||||
- Merge operations can require approval
|
||||
|
||||
## Templates
|
||||
|
||||
The system includes template tags for displaying version control information:
|
||||
|
||||
```html
|
||||
{% load version_control_tags %}
|
||||
|
||||
{% version_status object %}
|
||||
{% branch_selector %}
|
||||
{% history_list object %}
|
||||
```
|
||||
|
||||
## API Endpoints
|
||||
|
||||
Documentation for API endpoints can be found in `docs/version_control_api.md`.
|
||||
|
||||
## Database Considerations
|
||||
|
||||
The system uses your existing Django database configuration and creates these main tables:
|
||||
- history_tracking_versionbranch
|
||||
- history_tracking_changeset
|
||||
- history_tracking_versiontag
|
||||
- history_tracking_commentthread
|
||||
|
||||
Plus historical tables for each tracked model.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
Common issues and solutions:
|
||||
|
||||
1. Performance Issues
|
||||
- Check batch sizes
|
||||
- Verify cache configuration

|
||||
|
||||
## Model Integration
|
||||
### Key Decisions
|
||||
|
||||
### Making Models Version-Controlled
|
||||
To add version control to any model, inherit from `HistoricalModel`:
|
||||
#### 1. Infrastructure Integration
|
||||
- **Decision**: Leverage existing Django database and Redis infrastructure
|
||||
- **Rationale**:
|
||||
- Reduces operational complexity

||||
- Utilizes existing backup and monitoring systems
|
||||
- **Impact**: Simplified deployment and maintenance
|
||||
|
||||
#### 2. Architecture Pattern
|
||||
- **Decision**: Implement as a Django app (history_tracking)
|
||||
- **Rationale**:

||||
## Implementation Details
|
||||
|
||||
### Core Components
|
||||
1. Models
|
||||
- HistoricalModel (base class)
|
||||
- VersionBranch (branch management)
|
||||
- ChangeSet (atomic changes)
|
||||
- CommentThread (review system)
|
||||
|
||||
2. Features
|
||||
- Branch management
|
||||
- Change tracking
|
||||
- Merge operations
|
||||
- Review system
|
||||
- Performance monitoring
|
||||
|
||||
3. Integration Points
|
||||
- Model versioning
|
||||
- Template components
|
||||
- API endpoints
|
||||
- Admin interface
|
||||
|
||||
### Usage Patterns
|
||||
|
||||
#### Model Integration
|
||||
```python
|
||||
from history_tracking.models import HistoricalModel
|
||||
|
||||
class YourModel(HistoricalModel):
|
||||
# Your model fields here
|
||||
name = models.CharField(max_length=255)
|
||||
|
||||
class Meta:
|
||||
# Your meta options
|
||||
# Automatic version control capabilities
|
||||
pass
|
||||
```
|
||||
|
||||
This automatically provides:
|
||||
- Full version history
|
||||
- Change tracking
|
||||
- Branch support
|
||||
- Merge capabilities
|
||||
|
||||
### Example Integration (from parks/models.py)
|
||||
#### Branch Management
|
||||
```python
|
||||
from history_tracking.models import HistoricalModel
|
||||
|
||||
class Park(HistoricalModel):
|
||||
name = models.CharField(max_length=255)
|
||||
description = models.TextField()
|
||||
|
||||
def save(self, *args, **kwargs):
|
||||
# Changes will be automatically tracked
|
||||
super().save(*args, **kwargs)
|
||||
with branch_context(branch):
|
||||
# Changes tracked in specific branch
|
||||
model.save()
|
||||
```
|
||||
|
||||
## Usage Guide
|
||||
|
||||
### Basic Version Control Operations
|
||||
|
||||
1. Creating a Branch
|
||||
#### Batch Operations
|
||||
```python
|
||||
from history_tracking.managers import BranchManager
|
||||
|
||||
# Create a new feature branch
|
||||
branch_manager = BranchManager()
|
||||
feature_branch = branch_manager.create_branch(
|
||||
name="feature/new-park-details",
|
||||
user=request.user
|
||||
)
|
||||
with BatchOperation() as batch:
|
||||
# Efficient handling of multiple changes
|
||||
batch.process_changes(changes)
|
||||
```
|
||||
|
||||
2. Recording Changes
|
||||
```python
|
||||
from history_tracking.signals import ChangesetContextManager
|
||||
## Development Guidelines
|
||||
|
||||
# Making changes in a specific branch
|
||||
with ChangesetContextManager(branch=feature_branch, user=request.user):
|
||||
park = Park.objects.get(id=1)
|
||||
park.description = "Updated description"
|
||||
park.save() # Change is automatically tracked in the branch
|
||||
```
|
||||
### Best Practices
|
||||
1. Use batch operations for multiple changes
|
||||
2. Implement proper branch management
|
||||
3. Handle merge conflicts explicitly
|
||||
4. Monitor performance metrics
|
||||
5. Cache frequently accessed data
|
||||
|
||||
3. Merging Changes
|
||||
```python
|
||||
# Merge feature branch back to main
|
||||
success, conflicts = branch_manager.merge_branches(
|
||||
source=feature_branch,
|
||||
target=main_branch,
|
||||
user=request.user
|
||||
)
|
||||
### Anti-Patterns to Avoid
|
||||
1. Direct model changes outside branch context
|
||||
2. Inefficient querying of version history
|
||||
3. Ignoring batch operations for bulk changes
|
||||
4. Manual cache management
|
||||
|
||||
if not success:
|
||||
# Handle merge conflicts
|
||||
for conflict in conflicts:
|
||||
# Resolve conflicts through UI or programmatically
|
||||
pass
|
||||
```
|
||||
## Monitoring and Maintenance
|
||||
|
||||
4. Working with Tags
|
||||
```python
|
||||
from history_tracking.models import VersionTag
|
||||
### Performance Monitoring
|
||||
- Operation timing metrics
|
||||
- Cache hit rates
|
||||
- Database query patterns
|
||||
- Memory usage
|
||||
- API response times
|
||||
|
||||
# Tag a specific version
|
||||
VersionTag.objects.create(
|
||||
name="v1.0.0",
|
||||
branch=main_branch,
|
||||
content_type=ContentType.objects.get_for_model(park),
|
||||
object_id=park.id,
|
||||
created_by=user
|
||||
)
|
||||
```
|
||||
### Health Checks
|
||||
- Branch integrity
|
||||
- Cache consistency
|
||||
- Database indexes
|
||||
- Query performance
|
||||
- System resources
|
||||
|
||||

|
||||
## Support and Maintenance
|
||||
|
||||
2. Change Tracking
|
||||
- Make atomic, related changes
|
||||
- Provide clear change descriptions
|
||||
- Group related changes in a single changeset
|
||||
- Review changes before merging
|
||||
### Common Issues
|
||||
1. Cache invalidation
|
||||
2. Merge conflicts
|
||||
3. Performance optimization
|
||||
4. Data consistency
|
||||
|
||||
3. Conflict Resolution
|
||||

|
||||
- Clean up old branches and tags
|
||||
- Monitor system performance
|
||||
|
||||
## Error Handling
|
||||
|
||||
1. Common Issues
|
||||
```python
|
||||
try:
|
||||
branch_manager.merge_branches(source, target)
|
||||
except ValidationError as e:
|
||||
# Handle validation errors
|
||||
except MergeConflict as e:
|
||||
# Handle merge conflicts
|
||||
```
|
||||
|
||||
2. Conflict Resolution
|
||||
```python
|
||||
from history_tracking.utils import resolve_conflicts
|
||||
|
||||
resolved = resolve_conflicts(
|
||||
source_branch=source,
|
||||
target_branch=target,
|
||||
resolutions={
|
||||
'conflict_id': 'resolution_type', # 'source', 'target', or 'manual'
|
||||
},
|
||||
manual_resolutions={
|
||||
'conflict_id': 'manual resolution content'
|
||||
},
|
||||
user=request.user
|
||||
)
|
||||
```
|
||||
|
||||
## System Maintenance
|
||||
|
||||
1. Regular Tasks
|
||||
- Clean up old branches
|
||||
- Archive old versions
|
||||
- Verify data integrity
|
||||
- Monitor system health
|
||||
|
||||
2. Monitoring
|
||||
```python
|
||||
from history_tracking.utils import get_system_metrics
|
||||
|
||||
metrics = get_system_metrics()
|
||||
# Check branch counts, merge success rates, etc.
|
||||
```
|
||||
|
||||
## Security Considerations
|

|
||||
|
||||
2. Data Protection
|
||||
- Historical data is preserved
|
||||
- Audit logs are maintained
|
||||
- Sensitive data is handled securely
|
||||
- Backups include version history
|
||||
|
||||

## Version Control Patterns
|
||||
|
||||
### Change Management
|
||||
1. Batch Processing
|
||||
```python
|
||||
class BatchChangeProcessor:
|
||||
def process_changes(self, changes, chunk_size=100):
|
||||
"""Process changes in efficient batches"""
|
||||
with transaction.atomic():
|
||||
for chunk in chunked_queryset(changes, chunk_size):
|
||||
self._process_chunk(chunk)
|
||||
```
|
||||
|
||||
2. Caching Strategy
|
||||
```python
|
||||
class VersionCache:
|
||||
def cache_history(self, instance):
|
||||
"""Cache version history with TTL"""
|
||||
key = f"version_history_{instance.pk}"
|
||||
if not cache.get(key):
|
||||
history = instance.get_history()
|
||||
cache.set(key, history, timeout=3600)
|
||||
```
|
||||
|
||||
3. Change Tracking
|
||||
```python
|
||||
class ChangeTracker:
|
||||
def track_changes(self, instance):
|
||||
"""Track changes with metadata"""
|
||||
return {
|
||||
'changes': self._diff_changes(instance),
|
||||
'metadata': self._collect_metadata(),
|
||||
'performance': self._get_metrics()
|
||||
}
|
||||
```
|
||||
|
||||
### Performance Optimization
|
||||
|
||||
1. Query Patterns
|
||||
```python
|
||||
class HistoryQuerySet:
|
||||
def optimized_history(self):
|
||||
"""Optimized history query"""
|
||||
return self.select_related('branch')\
|
||||
.prefetch_related('changes')\
|
||||
.defer('large_fields')
|
||||
```
|
||||
|
||||
2. Async Operations
|
||||
```python
|
||||
class AsyncVersionControl:
|
||||
async def process_large_changes(self):
|
||||
"""Handle large changes asynchronously"""
|
||||
async with atomic():
|
||||
# Async processing logic
|
||||
```
|
||||
|
||||
3. Archiving Strategy
|
||||

|
||||
class HistoryArchiver:
|
||||
def archive_old_versions(self, age_days=90):
