Main engine for anime series management with async support, progress callbacks, and cancellation.
**Key Methods:**
- `search(words)` - Search for anime series
- `download(serie_folder, season, episode, key, language)` - Download an episode
- `rescan()` - Rescan directory for missing episodes
- `get_all_series_from_data_files()` - Load all series from data files in the anime directory (used for database sync on startup)
### Data File to Database Sync
On application startup, the system automatically syncs series from data files to the database:
1. After `download_service.initialize()` succeeds
2. `SeriesApp.get_all_series_from_data_files()` loads all series from `data` files
3. Each series is added to the database via `SerieList.add_to_db()`
4. Existing series are skipped (no duplicates)
5. Sync continues silently even if individual series fail
This ensures that series metadata stored in filesystem data files is available in the database for the web application.
### Callback System (`src/core/interfaces/callbacks.py`)
- `ProgressCallback`, `ErrorCallback`, `CompletionCallback`

## 📋 TODO Tasks
### Task 1: Add `get_all_series_from_data_files()` Method to SeriesApp
**Status**: [x] Completed
**Description**: Add a new method to `SeriesApp` that returns all series data found in data files from the filesystem.
**File to Modify**: `src/core/SeriesApp.py`
**Requirements**:
1. Add a new method `get_all_series_from_data_files() -> List[Serie]` to `SeriesApp`
2. This method should scan the `directory_to_search` for all data files
3. Load and return all `Serie` objects found in data files
4. Use the existing `SerieList.load_series()` pattern for file discovery
5. Return an empty list if no data files are found
6. Include proper logging for debugging
7. Method should be synchronous (can be wrapped with `asyncio.to_thread` if needed)
**Implementation Details**:
```python
def get_all_series_from_data_files(self) -> List[Serie]:
"""
Get all series from data files in the anime directory.
Scans the directory_to_search for all 'data' files and loads
the Serie metadata from each file.
Returns:
List of Serie objects found in data files
"""
# Use SerieList's file-based loading to get all series
# Return list of Serie objects from self.list.keyDict.values()
```
**Acceptance Criteria**:
- [x] Method exists in `SeriesApp`
- [x] Method returns `List[Serie]`
- [x] Method scans filesystem for data files
- [x] Proper error handling for missing/corrupt files
- [x] Logging added for operations
- [x] Unit tests written and passing
---
### Task 2: Sync Series from Data Files to Database on Setup Complete
**Status**: [x] Completed
**Description**: When the application setup is complete (anime directory configured), automatically sync all series from data files to the database.
**Files to Modify**:
- `src/server/fastapi_app.py` (lifespan function)
- `src/server/services/` (if needed for service layer)
**Requirements**:
1. After `download_service.initialize()` succeeds in the lifespan function
2. Call `SeriesApp.get_all_series_from_data_files()` to get all series
3. For each series, use `SerieList.add_to_db()` to save to database (uses existing DB schema)
4. Skip series that already exist in database (handled by `add_to_db`)
5. Log the sync progress and results
6. Do NOT modify database model definitions
**Implementation Details**:
```python
# In lifespan function, after download_service.initialize():
try:
from src.server.database.connection import get_db_session
# Get all series from data files using SeriesApp
series_app = SeriesApp(settings.anime_directory)
all_series = series_app.get_all_series_from_data_files()
if all_series:
async with get_db_session() as db:
serie_list = SerieList(settings.anime_directory, db_session=db, skip_load=True)
added_count = 0
for serie in all_series:
result = await serie_list.add_to_db(serie, db)
if result:
added_count += 1
await db.commit()
logger.info("Synced %d new series to database", added_count)
except Exception as e:
logger.warning("Failed to sync series to database: %s", e)
```
**Acceptance Criteria**:
- [x] Series from data files are synced to database on startup
- [x] Existing series in database are not duplicated
- [x] Database schema is NOT modified
- [x] Proper error handling (app continues even if sync fails)
- [x] Logging added for sync operations
- [x] Integration tests written and passing
---
### Task 3: Validation - Verify Data File to Database Sync
**Status**: [x] Completed
**Description**: Create validation tests to ensure the data file to database sync works correctly.
**File to Create**: `tests/integration/test_data_file_db_sync.py`
**Requirements**:
1. Test `get_all_series_from_data_files()` returns correct data
2. Test that series are correctly added to database
3. Test that duplicate series are not created
4. Test that sync handles empty directories gracefully
5. Test that sync handles corrupt data files gracefully
6. Test end-to-end startup sync behavior
**Test Cases**:
```python
class TestDataFileDbSync:
"""Test data file to database synchronization."""
async def test_get_all_series_from_data_files_returns_list(self):
"""Test that get_all_series_from_data_files returns a list."""
pass
async def test_get_all_series_from_data_files_empty_directory(self):
"""Test behavior with empty anime directory."""
pass
async def test_series_sync_to_db_creates_records(self):
"""Test that series are correctly synced to database."""
pass
async def test_series_sync_to_db_no_duplicates(self):
"""Test that duplicate series are not created."""

"""Test that corrupt data files don't crash the sync."""
pass
async def test_startup_sync_integration(self):
"""Test end-to-end startup sync behavior."""
pass
```
**Acceptance Criteria**:
- [x] All test cases implemented
- [x] Tests use pytest async fixtures
- [x] Tests use temporary directories for isolation
- [x] Tests cover happy path and error cases
- [x] All tests passing
- [x] Code coverage > 80% for new code
