# 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
- Monitor database queries
- Review parallel processing settings
2. Cache Issues
- Verify Redis connection
- Check cache key conflicts
- Monitor cache hit rates
3. Database Issues
- Check indexing
- Monitor query performance
- Review database connection pool settings

## 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
```
This automatically provides:
- Full version history
- Change tracking
- Branch support
- Merge capabilities
### Example Integration (from parks/models.py)
```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)
```
## Usage Guide
### Basic Version Control Operations
1. Creating a Branch
```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
)
```
2. Recording Changes
```python
from history_tracking.signals import ChangesetContextManager
# 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
```
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
)
if not success:
# Handle merge conflicts
for conflict in conflicts:
# Resolve conflicts through UI or programmatically
# Automatic version control capabilities
pass
```
4. Working with Tags
#### Branch Management
```python
from history_tracking.models import VersionTag
# 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
)
with branch_context(branch):
# Changes tracked in specific branch
model.save()
```
## UI Integration
### HTMX Components
The system provides HTMX-powered components for real-time version control:
1. Version Control Panel
```html
{% include "history_tracking/version_control_panel.html" %}
```
2. Branch Selection
```html
<div hx-get="{% url 'history:branch-list' %}"
hx-trigger="load, branch-updated from:body">
</div>
```
3. Change History
```html
<div hx-get="{% url 'history:history-view' %}?branch={{ branch.name }}"
hx-trigger="load, branch-selected from:body">
</div>
```
## Best Practices
1. Branch Management
- Create feature branches for significant changes
- Use descriptive branch names (e.g., "feature/new-park-system")
- Clean up merged branches
- Regularly sync with main branch
2. Change Tracking
- Make atomic, related changes
- Provide clear change descriptions
- Group related changes in a single changeset
- Review changes before merging
3. Conflict Resolution
- Resolve conflicts promptly
- Communicate with team members about overlapping changes
- Test after resolving conflicts
- Document resolution decisions
4. Performance
- Use changesets for bulk operations
- Index frequently queried fields
- Clean up old branches and tags
- Monitor system performance
## Error Handling
1. Common Issues
#### Batch Operations
```python
try:
branch_manager.merge_branches(source, target)
except ValidationError as e:
# Handle validation errors
except MergeConflict as e:
# Handle merge conflicts
with BatchOperation() as batch:
# Efficient handling of multiple changes
batch.process_changes(changes)
```
2. Conflict Resolution
```python
from history_tracking.utils import resolve_conflicts
## Development Guidelines
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
)
```
### 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
## System Maintenance
### 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
1. Regular Tasks
- Clean up old branches
- Archive old versions
- Verify data integrity
- Monitor system health
## Monitoring and Maintenance
2. Monitoring
```python
from history_tracking.utils import get_system_metrics
### Performance Monitoring
- Operation timing metrics
- Cache hit rates
- Database query patterns
- Memory usage
- API response times
metrics = get_system_metrics()
# Check branch counts, merge success rates, etc.
```
### Health Checks
- Branch integrity
- Cache consistency
- Database indexes
- Query performance
- System resources
## Security Considerations
## Future Considerations
1. Access Control
- All VCS operations require authentication
- Branch operations are logged
- Merge operations require proper permissions
- Changes are tracked with user attribution
### Planned Enhancements
1. Advanced conflict resolution
2. Enhanced performance monitoring
3. Additional caching strategies
4. Improved UI components
2. Data Protection
- Historical data is preserved
- Audit logs are maintained
- Sensitive data is handled securely
- Backups include version history
