|
||||
**Directory Structure**:

```
|

|
||||
**Cache Key Strategies**:
|
||||
- `FilepathMethodStrategy`: For extractor methods (`extractor_{hash}_{method}`)
|
||||
- `APIRequestStrategy`: For API responses (`api_{service}_{hash}`)
|
||||
- `SimpleKeyStrategy`: For simple prefix+id patterns
|
||||
- `CustomStrategy`: User-defined key generation
|
||||
|
||||
**Cache Decorators**:
|
||||
- `@cached(strategy, ttl)`: Generic caching with configurable strategy
|
||||
- `@cached_method(ttl)`: Method caching (backward compatible)
|
||||
- `@cached_api(service, ttl)`: API response caching
|
||||
- `@cached_property(ttl)`: Cached property decorator
|
||||
|
||||
**Cache Manager Operations**:
|
||||
- `clear_all()`: Remove all cache entries
|
||||
- `clear_by_prefix(prefix)`: Clear specific cache type (tmdb_, extractor_, poster_)
|
||||
- `clear_expired()`: Remove expired entries
|
||||
- `get_stats()`: Comprehensive statistics
|
||||
- `clear_file_cache(file_path)`: Clear cache for specific file
|
||||
- `compact_cache()`: Remove empty directories
|
||||
|
||||
**Command Palette Integration**:
|
||||
- Access cache commands via Ctrl+P
|
||||
- 7 commands: View Stats, Clear All, Clear Extractors, Clear TMDB, Clear Posters, Clear Expired, Compact
|
||||
- Integrated using `CacheCommandProvider`
|
||||
|
||||
**Thread Safety**:
|
||||
- All operations protected by `threading.RLock`
|
||||
- Safe for concurrent extractor access
|
||||
|
||||
### Error Handling & Logging
|
||||
|
||||
**Exception Handling** (v0.7.0):
|
||||
- No bare `except:` clauses (all use specific exception types)
|
||||
- Language code conversions catch `(LookupError, ValueError, AttributeError)`
|
||||
- Network errors catch `(requests.RequestException, ValueError)`
|
||||
- All exceptions logged with context
|
||||
|
||||
**Logging Strategy**:
|
||||
- **Warning level**: Network failures, API errors, MediaInfo parse failures (user-facing issues)
|
||||
- **Debug level**: Language code conversions, metadata reads, MIME detection (technical details)
|
||||
- **Error level**: Formatter application failures (logged via `FormatterApplier`)
|
||||
|
||||
**Logger Usage**:
|
||||
```python
|
||||
import logging
|
||||
logger = logging.getLogger(__name__)
|
||||
|
||||
# Examples
|
||||
logger.warning(f"TMDB API request failed for {url}: {e}")
|
||||
logger.debug(f"Invalid language code '{lang_code}': {e}")
|
||||
logger.error(f"Error applying {formatter.__name__}: {e}")
|
||||
```
|
||||
|
||||
**Files with Logging**:
|
||||
- `renamer/extractors/filename_extractor.py` - Language code conversion errors
|
||||
- `renamer/extractors/mediainfo_extractor.py` - MediaInfo parse and language errors
|

**Status**: COMPLETED (Not in original plan, implemented proactively)
|
||||
**Test Status**: All 2130 tests passing (18 new cache tests added) ✅
|
||||
|
||||
### Overview
|
||||
Created a comprehensive, flexible cache subsystem to replace the monolithic cache.py with a modular architecture supporting multiple cache strategies and decorators.
|
||||
|
||||
### New Directory Structure
|
||||
```
|
||||
renamer/cache/
|
||||
├── __init__.py # Module exports and convenience functions
|
||||
├── core.py # Core Cache class (moved from cache.py)
|
||||
├── types.py # Type definitions (CacheEntry, CacheStats)
|
||||
├── strategies.py # Cache key generation strategies
|
||||
├── managers.py # CacheManager for operations
|
||||
└── decorators.py # Enhanced cache decorators
|
||||
```
|
||||
|
||||
### Cache Key Strategies
|
||||
**Created 4 flexible strategies**:
|
||||
- `FilepathMethodStrategy`: For extractor methods (`extractor_{hash}_{method}`)
|
||||
- `APIRequestStrategy`: For API responses (`api_{service}_{hash}`)
|
||||
- `SimpleKeyStrategy`: For simple prefix+id (`{prefix}_{identifier}`)
|
||||
- `CustomStrategy`: User-defined key generation
|
||||
|
||||
### Cache Decorators
|
||||
**Enhanced decorator system**:
|
||||
- `@cached(strategy, ttl)`: Generic caching with configurable strategy
|
||||
- `@cached_method(ttl)`: Method caching (backward compatible)
|
||||
- `@cached_api(service, ttl)`: API response caching
|
||||
- `@cached_property(ttl)`: Cached property decorator
|
||||
|
||||
### Cache Manager
|
||||
**7 management operations**:
|
||||
- `clear_all()`: Remove all cache entries
|
||||
- `clear_by_prefix(prefix)`: Clear specific cache type
|
||||
- `clear_expired()`: Remove expired entries
|
||||
- `get_stats()`: Comprehensive statistics
|
||||
- `clear_file_cache(file_path)`: Clear cache for specific file
|
||||
- `get_cache_age(key)`: Get entry age
|
||||
- `compact_cache()`: Remove empty directories
|
||||
|
||||
### Command Palette Integration
|
||||
**Integrated with Textual's command palette (Ctrl+P)**:
|
||||
- Created `CacheCommandProvider` class
|
||||
- 7 cache commands accessible via command palette:
|
||||
- Cache: View Statistics
|
||||
- Cache: Clear All
|
||||
- Cache: Clear Extractors
|
||||
- Cache: Clear TMDB
|
||||
- Cache: Clear Posters
|
||||
- Cache: Clear Expired
|
||||
- Cache: Compact
|
||||
- Commands appear alongside built-in system commands (theme, keys, etc.)
|
||||
- Uses `COMMANDS = App.COMMANDS | {CacheCommandProvider}` pattern
|
||||
|
||||
### Backward Compatibility
|
||||
- Old import paths still work: `from renamer.decorators import cached_method`
|
||||
- Existing extractors continue to work without changes
|
||||
- Old `cache.py` deleted, functionality fully migrated
|
||||
- `renamer.cache` now resolves to the package, not the file
|
||||
|
||||
### Files Created (7)
|
||||
- `renamer/cache/__init__.py`
|
||||
- `renamer/cache/core.py`
|
||||
- `renamer/cache/types.py`
|
||||
- `renamer/cache/strategies.py`
|
||||
- `renamer/cache/managers.py`
|
||||
- `renamer/cache/decorators.py`
|
||||
- `renamer/test/test_cache_subsystem.py` (18 tests)
|
||||
|
||||
### Files Modified (3)
|
||||
- `renamer/app.py`: Added CacheCommandProvider and cache manager
|
||||
- `renamer/decorators/__init__.py`: Import from new cache module
|
||||
- `renamer/screens.py`: Updated help text for command palette
|
||||
|
||||
### Testing
|
||||
- 18 new comprehensive cache tests
|
||||
- All test basic operations, strategies, decorators, and manager
|
||||
- Backward compatibility tests
|
||||
- Total: 2130 tests passing ✅

|
||||
**Status**: COMPLETED
|
||||
**Completed**: 2025-12-31
|
||||
|
||||
**What was done**:
|
||||
1. Created `renamer/extractors/base.py` with `DataExtractor` Protocol
|
||||
- Defines standard interface for all extractors
|
||||
- 23 methods covering all extraction operations
|
||||
- Comprehensive docstrings with examples
|
||||
- Type hints for all method signatures
|
||||
|
||||
2. Created `renamer/formatters/base.py` with Formatter ABCs
|
||||
- `Formatter`: Base ABC with abstract `format()` method
|
||||
- `DataFormatter`: For data transformations (sizes, durations, dates)
|
||||
- `TextFormatter`: For text transformations (case changes)
|
||||
- `MarkupFormatter`: For visual styling (colors, bold, links)
|
||||
- `CompositeFormatter`: For chaining multiple formatters
|
||||
|
||||
3. Updated package exports
|
||||
- `renamer/extractors/__init__.py`: Exports DataExtractor + all extractors
|
||||
- `renamer/formatters/__init__.py`: Exports all base classes + formatters
|
||||
|
||||
**Benefits**:
|
||||
- Provides clear contract for extractor implementations
|
||||
- Enables runtime protocol checking
|
||||
- Improves IDE autocomplete and type checking
|
||||
- Foundation for future refactoring of existing extractors
|
||||
|
||||
**Test Status**: All 2130 tests passing ✅
|
||||
|
||||
**Files Created (2)**:
|
||||
- `renamer/extractors/base.py` (258 lines)
|
||||
- `renamer/formatters/base.py` (151 lines)
|
||||

### 2.5 Add App Commands to Command Palette ✅ COMPLETED
|
||||
**Status**: COMPLETED
|
||||
**Completed**: 2025-12-31
|
||||
|
||||
**What was done**:
|
||||
1. Created `AppCommandProvider` class in `renamer/app.py`
|
||||
- Extends Textual's Provider for command palette integration
|
||||
- Implements async `search()` method with fuzzy matching
|
||||
- Provides 8 main app commands:
|
||||
- **Open Directory** - Open a directory to browse (o)
|
||||
- **Scan Directory** - Scan current directory (s)
|
||||
- **Refresh File** - Refresh metadata for selected file (f)
|
||||
- **Rename File** - Rename the selected file (r)
|
||||
- **Toggle Display Mode** - Switch technical/catalog view (m)
|
||||
- **Toggle Tree Expansion** - Expand/collapse tree nodes (p)
|
||||
- **Settings** - Open settings screen (Ctrl+S)
|
||||
- **Help** - Show keyboard shortcuts (h)
|
||||
|
||||
2. Updated `COMMANDS` class variable
|
||||
- Changed from: `COMMANDS = App.COMMANDS | {CacheCommandProvider}`
|
||||
- Changed to: `COMMANDS = App.COMMANDS | {CacheCommandProvider, AppCommandProvider}`
|
||||
- Both cache and app commands now available in command palette
|
||||
|
||||
3. Command palette now provides:
|
||||
- 7 cache management commands
|
||||
- 8 app operation commands
|
||||
- All built-in Textual commands (theme switcher, etc.)
|
||||
- **Total: 15+ commands accessible via Ctrl+P**
|
||||
|
||||
**Benefits**:
|
||||
- **Unified interface** - All app operations accessible from one place
|
||||
- **Keyboard-first workflow** - No need to remember all shortcuts
|
||||
- **Fuzzy search** - Type partial names to find commands
|
||||
- **Discoverable** - Users can explore available commands
|
||||
- **Consistent UX** - Follows Textual command palette patterns
|
||||
|
||||
**Test Status**: All 2130 tests passing ✅
|
||||
|
||||
