 Phase 2: Fix RedisConfig to Only Connect (Not Start) 🔴 Refactor RedisConfig class to remove Redis server startup logic and focus only on connection management
Context: ✅ COMPLETED: Successfully refactored RedisConfig class to remove Redis server startup logic and focus only on connection management: RedisConfig Refactoring:

Removed all subprocess-based Redis server startup/shutdown logic
Removed start_redis_if_needed(), stop_redis_if_needed(), _wait_for_redis_ready(), _is_redis_server_available() methods
Enhanced get_redis_client() with connection pooling, timeouts, and proper error handling
Added validate_connection() method for detailed Redis status information
Added close_client() method for proper connection cleanup
Improved error handling and logging throughout

Environment Configuration:

Deprecated REDIS_DATA_DIR, REDIS_STARTUP_TIMEOUT, MANAGE_REDIS_LIFECYCLE settings
Added deprecation comments explaining Redis should be externally managed

Application Lifespan (setup.py):

Created: 2025-05-23 22:41:33.855764 | Updated: 2025-05-24 10:15:58.818750 | Priority: High


 Phase 3: Implement Redis Dependency Injection 🔴 Create proper FastAPI dependency injection for Redis clients with connection pooling
Context: ✅ COMPLETED: Successfully implemented comprehensive Redis dependency injection for FastAPI with multiple dependency variants: Redis Client Dependencies Implemented:

get_redis_client()- Standard Redis client (fails fast with HTTP 503)

For endpoints that require Redis to function properly
Raises HTTPException(503) if Redis unavailable


get_redis_client_optional()- Optional Redis client (graceful degradation)

Returns None instead of raising exceptions
For endpoints that can provide basic functionality without Redis


get_redis_client_managed()- Managed Redis client (automatic cleanup)

Returns RedisClientManager for guaranteed resource cleanup
Uses async context manager pattern


RedisClientManager- Context manager class

Ensures proper connection cleanup via aenter/aexit
Handles cleanup errors gracefully


Repository Dependencies Implemented: 5. get_session_repository() - SessionRepository with Redis dependency

Uses get_redis_client internally, fails fast
Location: core/repositories/dependencies.py (to avoid circular imports)


get_session_repository_optional()- Optional SessionRepository

Uses get_redis_client_optional, returns None if Redis unavailable
Location: core/repositories/dependencies.py (to avoid circular imports)


Circular Import Fix:

✅ Moved repository dependencies to core/repositories/dependencies.py
✅ Updated imports in redis_test.py and other modules
✅ Updated repositories init.py to export dependencies
✅ Fixed server startup issues caused by circular imports

Testing Infrastructure:

Added comprehensive test endpoints in /api/v2/debug/redis/
Integrated redis_test router into debug module
All dependency variants have dedicated test endpoints

Key Features:

✅ Multiple dependency variants for different error handling strategies
✅ Proper HTTP status codes (503 for service unavailable)
✅ Comprehensive error handling and logging
✅ Type hints and documentation for all functions
✅ Context manager for guaranteed resource cleanup
✅ Repository-level dependencies for higher-level abstractions
✅ Test endpoints to verify dependency injection works correctly
✅ Circular import resolution with proper module organization

Files Modified:

src/agent_c_api/api/dependencies.py - Added Redis client dependencies
src/agent_c_api/core/repositories/dependencies.py - Added repository dependencies (NEW)
src/agent_c_api/core/repositories/__init__.py - Updated exports
src/agent_c_api/api/v2/debug/__init__.py - Integrated redis_test router
src/agent_c_api/api/v2/debug/redis_test.py - Updated imports
.scratch/redis_dependency_injection_implementation.md - Updated documentation

Ready for Phase 4: Services can now be updated to use these dependencies instead of manual Redis client creation.
Created: 2025-05-23 22:41:39.099342 | Updated: 2025-05-24 12:32:52.379118 | Priority: High


 Phase 4: Update Services to Use Dependency Injection Refactor SessionRepository and related services to use proper dependency injection for Redis clients
Context: ✅ COMPLETED: Successfully implemented Phase 4 - Update Services to Use Dependency Injection Services Updated:

✅ SessionService (api/v2/sessions/services.py)

Replaced manual RedisConfig.get_redis_client() with get_session_repository() dependency
Updated get_session_service() function to use dependency injection
Eliminated manual Redis client and repository creation


✅ UserService (api/v2/users/services.py)

Refactored to accept UserRepository via constructor dependency injection
Added get_user_service() dependency function using get_user_repository()
Simplified core service creation by eliminating async Redis client creation
Removed manual RedisConfig.get_redis_client() calls


✅ ChatService (api/v2/sessions/chat.py)

Updated to accept Redis client via constructor dependency injection
Modified get_chat_service() to use get_redis_client() dependency
Refactored _get_core_service() to use injected Redis client instead of manual creation
Made all core service calls synchronous (removed unnecessary await)


Repository Dependencies Added:

✅ get_user_repository() and get_user_repository_optional()
✅ Updated core/repositories/__init__.py to export new dependencies
⚠️ ChatRepository dependencies removed - ChatRepository requires session_id from endpoint path, so ChatService creates repositories directly using injected Redis client

Syntax Error Fixed:

✅ Fixed parameter ordering issue in dependencies.py that caused startup failure
✅ Removed ChatRepository dependencies that had invalid parameter signatures
✅ ChatService pattern maintained - uses injected Redis client to create session-specific repositories

Key Improvements:

✅ Eliminated all manual Redis client creation in service layers
✅ Proper FastAPI dependency injection throughout the service architecture
✅ Consistent error handling via dependency injection (HTTP 503 for Redis unavailable)
✅ Simplified service constructors with clear dependency requirements
✅ Better separation of concerns - services focus on business logic, not infrastructure

Verification:

✅ All RedisConfig.get_redis_client() calls removed from service layers
✅ Only remaining calls are in api/dependencies.py (correct - these are the DI functions)
✅ Import test script updated and syntax errors resolved
✅ Server startup issue fixed

Result: Phase 4 is now complete and functional. All services use proper FastAPI dependency injection for Redis access, eliminating manual client creation and following the dependency injection pattern established in Phase 3.

Task: f9c8c756-67c2-4358-b008-f64b4eda0011
When updating services to use dependency injection, work systematically from the bottom up: repositories first, then services, then endpoints. Create repository-level dependencies for each repository type (SessionRepository, UserRepository, ChatRepository) with both standard and optional variants. For services that need session-specific repositories (like ChatService), inject the Redis client and create repositories as needed rather than trying to inject session-specific repositories. Always verify that manual client creation is completely eliminated and test imports to catch circular dependency issues early.
