feat: Implement comprehensive progress callback system
- Created callback interfaces (ProgressCallback, ErrorCallback, CompletionCallback) - Defined rich context objects (ProgressContext, ErrorContext, CompletionContext) - Implemented CallbackManager for managing multiple callbacks - Integrated callbacks into SerieScanner for scan progress reporting - Enhanced SeriesApp with download progress tracking via callbacks - Added error and completion notifications throughout core operations - Maintained backward compatibility with legacy callback system - Created 22 comprehensive unit tests with 100% pass rate - Updated infrastructure.md with callback system documentation - Removed completed tasks from instructions.md The callback system provides: - Real-time progress updates with percentage and phase tracking - Comprehensive error reporting with recovery information - Operation completion notifications with statistics - Thread-safe callback execution with exception handling - Support for multiple simultaneous callbacks per type

## Progress Callback System
|
||||
|
||||
### Overview
|
||||
|
||||
A comprehensive callback system for real-time progress reporting, error handling, and operation completion notifications across core operations (scanning, downloading, searching).
|
||||
|
||||
### Architecture
|
||||
|
||||
- **Interface-based Design**: Abstract base classes define callback contracts
|
||||
- **Context Objects**: Rich context information for each callback type
|
||||
- **Callback Manager**: Centralized management of multiple callbacks
|
||||
- **Thread-safe**: Exception handling prevents callback errors from breaking operations
|
||||
|
||||
### Components
|
||||
|
||||
#### Callback Interfaces (`src/core/interfaces/callbacks.py`)
|
||||
|
||||
- `ProgressCallback`: Reports operation progress updates
|
||||
- `ErrorCallback`: Handles error notifications
|
||||
- `CompletionCallback`: Notifies operation completion
|
||||
|
||||
#### Context Classes
|
||||
|
||||
- `ProgressContext`: Current progress, percentage, phase, and metadata
|
||||
- `ErrorContext`: Error details, recoverability, retry information
|
||||
- `CompletionContext`: Success status, results, and statistics
|
||||
|
||||
#### Enums
|
||||
|
||||
- `OperationType`: SCAN, DOWNLOAD, SEARCH, INITIALIZATION
|
||||
- `ProgressPhase`: STARTING, IN_PROGRESS, COMPLETING, COMPLETED, FAILED, CANCELLED
|
||||
|
||||
#### Callback Manager
|
||||
|
||||
- Register/unregister multiple callbacks per type
|
||||
- Notify all registered callbacks with context
|
||||
- Exception handling for callback errors
|
||||
- Support for clearing all callbacks
|
||||
|
||||
### Integration
|
||||
|
||||
#### SerieScanner
|
||||
|
||||
- Reports scanning progress (folder by folder)
|
||||
- Notifies errors for failed folder scans
|
||||
- Reports completion with statistics
|
||||
|
||||
#### SeriesApp
|
||||
|
||||
- Download progress reporting with percentage
|
||||
- Scan progress through SerieScanner integration
|
||||
- Error notifications for all operations
|
||||
- Completion notifications with results
|
||||
|
||||
### Usage Example
|
||||
|
||||
```python
|
||||
from src.core.interfaces.callbacks import (
|
||||
CallbackManager,
|
||||
ProgressCallback,
|
||||
ProgressContext
|
||||
)
|
||||
|
||||
class MyProgressCallback(ProgressCallback):
|
||||
def on_progress(self, context: ProgressContext):
|
||||
print(f"{context.message}: {context.percentage:.1f}%")
|
||||
|
||||
# Register callback
|
||||
manager = CallbackManager()
|
||||
manager.register_progress_callback(MyProgressCallback())
|
||||
|
||||
# Use with SeriesApp
|
||||
app = SeriesApp(directory, callback_manager=manager)
|
||||
```
|
||||
|
||||
## Recent Infrastructure Changes
|
||||
|
||||
### Progress Callback System (October 2025)
|
||||
|
||||
Implemented a comprehensive progress callback system for real-time operation tracking.
|
||||
|
||||
#### Changes Made
|
||||
|
||||
1. **Callback Interfaces**:
|
||||
|
||||
- Created abstract base classes for progress, error, and completion callbacks
|
||||
- Defined rich context objects with operation metadata
|
||||
- Implemented thread-safe callback manager
|
||||
|
||||
2. **SerieScanner Integration**:
|
||||
|
||||
- Added progress reporting for directory scanning
|
||||
- Implemented per-folder progress updates
|
||||
- Error callbacks for scan failures
|
||||
- Completion notifications with statistics
|
||||
|
||||
3. **SeriesApp Integration**:
|
||||
|
||||
- Integrated callback manager into download operations
|
||||
- Progress updates during episode downloads
|
||||
- Error handling with callback notifications
|
||||
- Completion callbacks for all operations
|
||||
- Backward compatibility with legacy callbacks
|
||||
|
||||
4. **Testing**:
|
||||
- 22 comprehensive unit tests
|
||||
- Coverage for all callback types
|
||||
- Exception handling verification
|
||||
- Multiple callback registration tests
|
||||
|
||||
