# Quality Issues and TODO List
# Aniworld Web Application Development Instructions
This document provides detailed tasks for AI agents to implement a modern web application for the Aniworld anime download manager. All tasks should follow the coding guidelines specified in the project's copilot instructions.
## Project Overview
The goal is to create a FastAPI-based web application that provides a modern interface for the existing Aniworld anime download functionality. The core anime logic should remain in `SeriesApp.py` while the web layer provides REST API endpoints and a responsive UI.
## Architecture Principles
- **Single Responsibility**: Each file/class has one clear purpose
- **Dependency Injection**: Use FastAPI's dependency system
- **Clean Separation**: Web layer calls core logic, never the reverse
- **File Size Limit**: Maximum 500 lines per file
- **Type Hints**: Use comprehensive type annotations
- **Error Handling**: Proper exception handling and logging
## Additional Implementation Guidelines
### Code Style and Standards
- **Type Hints**: Use comprehensive type annotations throughout all modules
- **Docstrings**: Follow PEP 257 for function and class documentation
- **Error Handling**: Implement custom exception classes with meaningful messages
- **Logging**: Use structured logging with appropriate log levels
- **Security**: Validate all inputs and sanitize outputs
- **Performance**: Use async/await patterns for I/O operations
## 📞 Escalation
If you encounter:
- Architecture issues requiring design decisions
- Tests that conflict with documented requirements
- Breaking changes needed
- Unclear requirements or expectations
**Document the issue and escalate rather than guessing.**

## 📊 Detailed Analysis: The 7 Quality Criteria
### 1️⃣ Code Follows PEP8 and Project Coding Standards
---
### 2️⃣ Type Hints Used Where Applicable
#### Missing Type Hints by Category
**Abstract Base Classes (Critical)**
**Service Classes**
**API Endpoints**
**Dependencies and Utils**
**Core Classes**
#### Invalid Type Hint Syntax
---
### 3️⃣ Clear, Self-Documenting Code Written
#### Missing or Inadequate Docstrings
**Module-Level Docstrings**
**Class Docstrings**
- [ ] `src/server/utils/dependencies.py` - `CommonQueryParams` class lacks docstring
**Method/Function Docstrings**
- [ ] `src/server/utils/logging.py` - Check helper functions
- [ ] `src/server/utils/template_helpers.py` - Check helper functions
#### Unclear Variable Names
#### Unclear Comments or Missing Context
- [ ] `src/core/providers/enhanced_provider.py` line 231
- Comment style inconsistent with rest of codebase
- [ ] `src/server/api/download.py` line 51
- Backward compatibility comment clear but needs more detail
---
### 4️⃣ Complex Logic Commented
#### Complex Algorithms Without Comments
**Episode Discovery Pattern Matching**
- [ ] `src/core/providers/streaming/*.py` files
- Regex patterns for extracting streams (complex)
- Each provider has different extraction logic
- Need comments explaining regex patterns
- Example: `src/core/providers/streaming/doodstream.py` line 35
**JSON/HTML Parsing Logic**
**Session Retry Configuration**
- [ ] `src/core/providers/enhanced_provider.py` lines 108-125
- Session retry configuration with backoff
- Line 115: status codes list needs explanation
- Comment should explain why these specific codes need retry
---
### 5️⃣ No Shortcuts or Hacks Used
#### Code Smells and Shortcuts
- [ ] `src/core/providers/streaming/Provider.py` line 7 - Abstract method implementation should not have pass
**Bare Pass Statements (Incomplete Implementation)**
**Duplicate Code**
- [ ] `src/cli/Main.py` vs `src/core/SeriesApp.py`
- Entire `SeriesApp` class duplicated (89 lines vs 590 lines)
- CLI version is oversimplified - should use core version
- Line 35-50 in CLI duplicates core initialization logic
- [ ] `src/core/providers/aniworld_provider.py` vs `src/core/providers/enhanced_provider.py`
- Headers dictionary duplicated (lines 38-50 similar)
- Provider list duplicated (line 38 vs line 45)
- User-Agent strings duplicated
**Global Variables (Temporary Storage)**
- [ ] `src/server/fastapi_app.py` line 73
- `series_app: Optional[SeriesApp] = None` global storage
- Should use FastAPI dependency injection instead
- Problematic for testing and multiple instances
**Logging Configuration Workarounds**
- [ ] `src/cli/Main.py` lines 12-22
- Manual logger handler removal is hacky
- `for h in logging.root.handlers: logging.root.removeHandler(h)` is a hack
- Should use proper logging configuration
- Multiple loggers created with file handlers at odd paths (line 26)
**Hardcoded Values**
- [ ] `src/core/providers/aniworld_provider.py` line 22
- `timeout = int(os.getenv("DOWNLOAD_TIMEOUT", 600))` at module level
- Should be in settings class
- [ ] `src/core/providers/aniworld_provider.py` lines 38, 47
- User-Agent strings hardcoded
- Provider list hardcoded
- [ ] `src/cli/Main.py` line 227
- Network path hardcoded: `"\\\\sshfs.r\\ubuntu@192.168.178.43\\media\\serien\\Serien"`
- Should be configuration
**Exception Handling Shortcuts**
- [ ] `src/core/providers/enhanced_provider.py` lines 410-421
- Bare `except Exception:` without specific types (line 418)
- Multiple overlapping exception handlers (lines 410-425)
- Should use specific exception hierarchy
- [ ] `src/server/api/anime.py` lines 35-39
- Bare `except Exception:` handlers should specify types
- [ ] `src/server/models/config.py` line 93
- `except ValidationError: pass` - silently ignores error
**Type Casting Workarounds**
- [ ] `src/server/api/download.py` line 52
- Complex `.model_dump(mode="json")` for serialization
- Should use proper model serialization methods
- [ ] `src/server/utils/dependencies.py` line 36
- Type casting with `.get()` and defaults scattered throughout
**Conditional Hacks**
- [ ] `src/server/utils/dependencies.py` line 260
- `running_tests = "PYTEST_CURRENT_TEST" in os.environ or "pytest" in sys.modules`
- Hacky test detection - should use proper test mode flag
---
### 6️⃣ Security Considerations Addressed
#### Authentication & Authorization
**Weak CORS Configuration**
- [ ] `src/server/fastapi_app.py` line 48
- `allow_origins=["*"]` allows any origin
- **HIGH RISK** in production
- Should be: `allow_origins=settings.allowed_origins` (environment-based)
- [ ] No CORS rate limiting by origin
**Missing Authorization Checks**
- [ ] `src/server/middleware/auth.py` lines 81-86
- Silent failure on missing auth for protected endpoints
- Should consistently return 401 status
- Some endpoints might bypass auth silently
**In-Memory Session Storage**
- [ ] `src/server/services/auth_service.py` line 51
- In-memory `_failed` dict resets on restart
- Attacker can restart process to bypass rate limiting
- Should use Redis or database
- [ ] Line 51 comment: "For now we update only in-memory"
- Indicates incomplete security implementation
#### Input Validation
**Unvalidated User Input**
- [ ] `src/cli/Main.py` line 80
- User input for file paths not validated
- Could allow path traversal attacks
- [ ] `src/core/SerieScanner.py` line 37
- Directory path `basePath` not validated
- Could read files outside intended directory
- [ ] `src/server/api/anime.py` line 70
- Search query not validated for injection
- [ ] `src/core/providers/aniworld_provider.py` line 300+
- URL parameters not sanitized
**Missing Parameter Validation**
- [ ] `src/core/providers/enhanced_provider.py` line 280
- Season/episode validation present but minimal
- [ ] `src/server/database/models.py`
- No length validation on string fields
- No range validation on numeric fields
#### Secrets and Credentials
**Hardcoded Secrets**
- [ ] `src/config/settings.py` line 9
- `jwt_secret_key: str = Field(default="your-secret-key-here", env="JWT_SECRET_KEY")`
- Default secret exposed in code
- Should have NO default, or random default
- [ ] `.env` file might contain secrets (if exists)
- Should be in .gitignore
**Plaintext Password Storage**
- [ ] `src/config/settings.py` line 12
- `master_password: Optional[str]` stored in env (development only)
- Should NEVER be used in production
- Add bold warning comment
**Master Password Implementation**
- [ ] `src/server/services/auth_service.py` line 71
- Minimum 8 character password requirement documented
- Should enforce stronger requirements (uppercase, numbers, symbols)
#### Data Protection
**No Encryption of Sensitive Data**
- [ ] Downloaded files not verified with checksums
- [ ] No integrity checking of stored data
- [ ] No encryption of sensitive config values
**File Permission Issues**
- [ ] `src/core/providers/aniworld_provider.py` line 26
- Log file created with default permissions
- Path: `"../../download_errors.log"` - relative path is unsafe
- Should use absolute paths with secure permissions
**Logging of Sensitive Data**
- [ ] Check all `logger.debug()` calls for parameter logging
- URLs might contain API keys
- Search queries might contain sensitive terms
- [ ] Example: `src/core/providers/enhanced_provider.py` line 260
- `logger.debug()` might log URLs with sensitive data
#### Network Security
**Unvalidated External Connections**
- [ ] `src/core/providers/aniworld_provider.py` line 60
- HTTP retry configuration but no SSL verification flag check
- [ ] `src/core/providers/enhanced_provider.py` line 115
- HTTP error codes 500-524 auto-retry without logging suspicious activity
**Missing SSL/TLS Configuration**
- [ ] Verify SSL certificate validation enabled
- [ ] Check for `verify=False` in requests calls (should be `True`)
#### Database Security
**No SQL Injection Protection**
- [ ] Check `src/server/database/service.py` for parameterized queries
- Should use SQLAlchemy properly (appears to be OK)
- [ ] String interpolation in queries should not exist
**No Database Access Control**
- [ ] Single database user for all operations
- [ ] No row-level security
- [ ] No audit logging of data changes
---
### 7️⃣ Performance Validated
#### Algorithmic Efficiency Issues
**File Scanning Performance**
- [ ] `src/core/SerieScanner.py` line 105+
- `__find_mp4_files()` - potential O(n²) complexity
- Recursive directory traversal not profiled
- No caching or incremental scanning
- Large directories (>10K files) might cause timeout
**Download Queue Processing**
- [ ] `src/server/services/download_service.py` line 240
- `self._pending_queue.remove(item)` - O(n) operation in deque
- Should use dict for O(1) lookup before removal
- Line 85-86: deque maxlen limits might cause data loss
**Provider Search Performance**
- [ ] `src/core/providers/enhanced_provider.py` line 220
- Multiple parsing strategies tried sequentially
- Should fail fast on obvious errors instead of trying all 3
- No performance metrics logged
**String Operations**
- [ ] `src/cli/Main.py` line 118
- Nested `sum()` with comprehensions - O(n\*m) complexity
- `total_episodes = sum(sum(len(ep) for ep in serie.episodeDict.values()) for serie in series)`
- No streaming/generator pattern
**Regular Expression Compilation**
- [ ] `src/core/providers/streaming/doodstream.py` line 35
- Regex patterns compiled on every call
- Should compile once at module level
- Example: `r"\$\.get\('([^']*\/pass_md5\/[^']*)'"` compiled repeatedly
#### Resource Usage Issues
**Memory Leaks/Unbounded Growth**
- [ ] `src/server/middleware/auth.py` line 34
- `self._rate: Dict[str, Dict[str, float]]` never cleaned
- Old IP addresses accumulate forever
- Solution: add timestamp-based cleanup
- [ ] `src/server/services/download_service.py` line 85-86
- `deque(maxlen=100)` and `deque(maxlen=50)` drop old items
- Might lose important history
**Connection Pool Configuration**
- [ ] `src/server/database/connection.py`
- Check if connection pooling is configured
- No explicit pool size limits found
- Could exhaust database connections
**Large Data Structure Initialization**
- [ ] `src/cli/Main.py` line 118
- Loading all series at once
- Should use pagination for large datasets
#### Caching Opportunities
**No Request Caching**
- [ ] `src/server/api/anime.py` - endpoints hit database every time
- No caching headers set
- `@cache` decorator could be used
- [ ] `src/core/providers/enhanced_provider.py`
- Search results not cached
- Same search query hits network repeatedly
**No Database Query Optimization**
- [ ] `src/server/services/anime_service.py`
- No eager loading (selectinload) for relationships
- N+1 query problems likely
- [ ] `src/server/database/service.py` line 200+
- Check for missing `.selectinload()` in queries
#### Concurrent Request Handling
**Thread Pool Sizing**
- [ ] `src/server/services/download_service.py` line 85
- `ThreadPoolExecutor(max_workers=max_concurrent_downloads)`
- Default is 2, should be configurable
- No queue depth limits
**Async/Sync Blocking Calls**
- [ ] `src/server/api/anime.py` line 30+
- Series list operations might block
- Database queries appear async (OK)
- [ ] `src/server/services/auth_service.py`
- Methods are synchronous but called from async endpoints
- Should verify no blocking calls
#### I/O Performance
**Database Query Count**
- [ ] `/api/v1/anime` endpoint
- Likely makes multiple queries for each series
- Should use single query with joins/eager loading
- Test with N series to find N+1 issues
**File I/O Optimization**
- [ ] `src/core/SerieScanner.py` line 140+
- Each folder reads data file
- Could batch reads or cache
**Network Request Optimization**
- [ ] `src/core/providers/enhanced_provider.py` line 115
- Retry strategy good
- No connection pooling verification
- Should check request timeout values
#### Performance Metrics Missing
- [ ] No performance monitoring for slow endpoints
- [ ] No database query logging
- [ ] No cache hit/miss metrics
- [ ] No background task performance tracking
- [ ] No file operation benchmarks

## 📋 Issues by File and Category
### Core Module Issues
#### `src/cli/Main.py`
- [ ] **Code Quality**: Class `SeriesApp` duplicates core `SeriesApp` from `src/core/SeriesApp.py`
- Consider consolidating or using inheritance
- Line 35: `_initialization_count` duplicated state tracking
- [ ] **Type Hints**: `display_series()` doesn't validate if `serie.name` is `None` before using it
- [ ] **Import Organization**: Imports not sorted (lines 1-11) - should follow isort convention
- [ ] **Error Handling**: `NoKeyFoundException` and `MatchNotFoundError` are bare except classes - need proper inheritance
- [ ] **Logging**: Logging configuration at module level should be in centralized config
#### `src/core/SeriesApp.py`
- [ ] **Global State**: Line 73 - `series_app: Optional[SeriesApp] = None` in `fastapi_app.py` uses global state
- Should use dependency injection instead
- [ ] **Complexity**: `Scan()` method is complex (80+ lines) - should be broken into smaller methods
- [ ] **Error Context**: `_handle_error()` doesn't provide enough context about which operation failed
#### `src/core/SerieScanner.py`
- [ ] **Code Quality**: `is_null_or_whitespace()` duplicates Python's `str.isspace()` - use built-in instead
- [ ] **Error Logging**: Lines 167-182 catch exceptions but only log, don't propagate context
- [ ] **Performance**: `__find_mp4_files()` might be inefficient for large directories - add progress callback
#### `src/core/providers/base_provider.py`
#### `src/core/providers/aniworld_provider.py`
- [ ] **Import Organization**: Lines 1-18 - imports not sorted (violates isort)
- [ ] **Global State**: Lines 24-26 - Multiple logger instances created at module level
- Should use centralized logging system
- [ ] **Hardcoding**: Line 42 - User-Agent string hardcoded (also at line 47 for Firefox)
- Extract to configuration constants
- [ ] **Type Hints**: Missing type hints on:
- `__init__()` method parameters (no return type on implicit constructor)
- Class attribute type annotations (line 41-62)
- [ ] **Magic Strings**: Line 38 - Hardcoded list of provider names should be enum
- [ ] **Configuration**: Timeouts hardcoded at line 22 - should use settings
#### `src/core/providers/enhanced_provider.py`
- [ ] **Type Hints**: Class constructor `__init__()` missing type annotations (lines 40-96)
- [ ] **Documentation**: Bare exception handlers at lines 418-419 - need specific exception types
- [ ] **Code Quality**: `with_error_recovery` decorator imported but usage unclear
- [ ] **Performance**: `_create_robust_session()` method not shown but likely creates multiple session objects
#### `src/core/interfaces/providers.py`
- [ ] Need to verify if any abstract methods lack type hints and docstrings
#### `src/core/exceptions/Exceptions.py`
- [ ] Need to verify custom exception hierarchy and documentation
---
### Server Module Issues
#### `src/server/fastapi_app.py`
- [ ] **Global State**: Line 73 - `series_app: Optional[SeriesApp] = None` stored globally

- Add comment: "Configure appropriately for production"
- Extract to settings with environment-based defaults
- [ ] **Error Handling**: `startup_event()` at line 79 - missing try-except to handle initialization failures
- [ ] **Type Hints**: `startup_event()` function missing type annotations
- [ ] **Documentation**: `broadcast_callback()` function inside event handler should be extracted to separate function
- [ ] **Logging**: No error logging if `settings.anime_directory` is None
#### `src/server/middleware/auth.py`
- [ ] **Performance**: In-memory rate limiter (line 34) will leak memory - never cleans up old entries
- Need periodic cleanup or use Redis for production
- [ ] **Security**: Line 46 - Rate limiting only 60-second window, should be configurable
- [ ] **Type Hints**: `dispatch()` method parameters properly typed, but return type could be explicit
- [ ] **Documentation**: `_get_client_ip()` method incomplete (line 94+ truncated)
- [ ] **Error Handling**: Lines 81-86 - Silent failure if protected endpoint and no auth
- Should return 401 consistently
#### `src/server/services/auth_service.py`
- [ ] **Documentation**: Line 68 - Comment says "For now we update only in-memory" indicates incomplete implementation
- Create task to persist password hash to configuration file
- [ ] **Type Hints**: `_verify_password()` at line 60 - no return type annotation (implicit `bool`)
- [ ] **Security**: Line 71 - Minimum password length 8 characters, should be documented as security requirement
- [ ] **State Management**: In-memory `_failed` dict (line 51) resets on process restart
- Document this limitation and suggest Redis/database for production
#### `src/server/database/service.py`
- [ ] **Documentation**: Service layer methods need detailed docstrings explaining:
- Database constraints
- Transaction behavior
- Cascade delete behavior
- [ ] **Error Handling**: Methods don't specify which SQLAlchemy exceptions they might raise
#### `src/server/database/models.py`
- [ ] **Documentation**: Model relationships and cascade rules well-documented
- ✅ Type hints present and comprehensive (well done)
- [ ] **Validation**: No model-level validation before database insert
- Consider adding validators for constraints
#### `src/server/services/download_service.py`
- [ ] **Performance**: Line 85 - `deque(maxlen=100)` for completed items - is this appropriate for long-running service?
- [ ] **Thread Safety**: Uses `ThreadPoolExecutor` but thread-safety of queue operations not clear
#### `src/server/utils/dependencies.py`
- [ ] **TODO Comments**: Lines 223 and 233 - TODO comments for unimplemented features:
- "TODO: Implement rate limiting logic"
- "TODO: Implement request logging logic"
- Create separate task items for these
#### `src/server/utils/system.py`
- [ ] **Exception Handling**: Line 255 - bare `pass` statement in exception handler
- Should at least log the exception
#### `src/server/api/anime.py`
- [ ] **Error Handling**: Lines 35-39 - Multiple bare `except Exception` handlers
- Need specific exception types and proper logging
- [ ] **Code Quality**: Lines 32-36 - Complex property access with `getattr()` chains
- Create helper function or model method to encapsulate
---
### Models and Pydantic Issues
#### `src/server/models/config.py`
- [ ] **Error Handling**: Line 93 - `ValidationError` caught but only silently passed?
- Should log or re-raise with context
---
### Utility and Configuration Issues
#### `src/config/settings.py`
- [ ] **Security**: Line 12 - `master_password` field stored in environment during development
- Add warning comment: "NEVER use this in production"
- [ ] **Documentation**: Settings class needs comprehensive docstring explaining each field
#### `src/infrastructure/logging/GlobalLogger.py`
- [ ] Need to review logging configuration for consistency
#### `src/server/utils/logging.py`
- [ ] Need to review for type hints and consistency with global logging
#### `src/server/utils/template_helpers.py`
- [ ] Need to review for type hints and docstrings
#### `src/server/utils/log_manager.py`
- [ ] Need to review for type hints and error handling
