This update improves session management reliability and ensures stale sessions are efficiently removed, enhancing overall application performance. --- gateway/session_cleanup.py | 196 +++++++ gateway/session_manager.py | 24 +- gateway/ws_handler.py | 4 +- main.py | 29 +- memory/redis_client.py | 92 +++- tests/test_gateway.py | 74 +-- tests/test_gateway_integration.py | 68 ++- tests/test_redis.py | 112 +++- tests/test_session_cleanup.py | 622 ++++++++++++++++++++++ tests/test_session_cleanup_e2e.py | 370 +++++++++++++ tests/test_session_cleanup_integration.py | 377 +++++++++++++ 11 files changed, 1831 insertions(+), 137 deletions(-) create mode 100644 gateway/session_cleanup.py create mode 100644 tests/test_session_cleanup.py create mode 100644 tests/test_session_cleanup_e2e.py create mode 100644 tests/test_session_cleanup_integration.py diff --git a/gateway/session_cleanup.py b/gateway/session_cleanup.py new file mode 100644 index 0000000..c66042f --- /dev/null +++ b/gateway/session_cleanup.py @@ -0,0 +1,196 @@ +"""Session cleanup service for removing stale session IDs from user index.""" + +import asyncio +from time import time + +from core.logger import get_logger +from memory.redis_client import RedisClient + +logger = get_logger(__name__) + +# Cleanup configuration +LOCK_KEY = "lock:session_cleanup" +LOCK_TTL = 240 # 4 minutes +CLEANUP_INTERVAL = 300 # 5 minutes +SCAN_BATCH_SIZE = 500 +USER_SESSIONS_PATTERN = "user_sessions:*" + + +class SessionCleanupService: + """Service for cleaning up stale session IDs from user_sessions index""" + + def __init__(self, redis_client: RedisClient): + """ + Initialize cleanup service. + + Args: + redis_client: Redis client instance + """ + self.redis = redis_client + self._running = False + + async def cleanup(self) -> dict[str, int]: + """ + Perform cleanup of stale session IDs. + + Returns: + Dictionary with cleanup metrics: + -

From aa334103a2a18b7120f3b82134aa9b611ba7ea95 Mon Sep 17 00:00:00 2001 From: Jenish-1235 Date: Fri, 19 Dec 2025 12:45:21 +0530 Subject: [PATCH 08/18] feat: Enhance Redis and session management capabilities - Add redis_max_connections setting to configure maximum Redis connections. - Refactor main.py to initialize Redis client with new connection settings. - Update health check endpoints to verify Redis connection status. - Remove unused database and Redis client creation functions. - Introduce idempotent session keys for WebSocket connections to improve session management. - Implement batch operations in Redis client for efficient session handling. - Update tests to reflect changes in session management and Redis interactions. These enhancements improve the application's performance and reliability in managing Redis connections and user sessions. --- api/health.py | 10 +- config.py | 20 +- core/__init__.py | 8 - core/app_state.py | 1 + core/database.py | 69 -- core/models/protocol.py | 61 +- core/models/session.py | 10 +- core/redis.py | 69 -- gateway/demux.py | 14 +- gateway/router.py | 36 +- gateway/session_cleanup.py | 23 +- gateway/session_manager.py | 198 ++- gateway/ws_handler.py | 338 ++++-- main.py | 64 +- memory/redis_client.py | 11 + pyproject.toml | 5 +- tests/api/__init__.py | 1 + .../test_health.py} | 2 +- tests/{ => api}/test_main.py | 6 +- tests/conftest.py | 5 +- tests/core/test_logger.py | 151 +++ tests/gateway/__init__.py | 1 + tests/gateway/test_demux.py | 155 +++ .../test_integration.py} | 56 +- tests/gateway/test_router.py | 166 +++ tests/{ => gateway}/test_session_cleanup.py | 24 +- .../{ => gateway}/test_session_cleanup_e2e.py | 56 +- .../test_session_cleanup_integration.py | 60 +- tests/gateway/test_session_manager.py | 462 +++++++ tests/gateway/test_ws_handler.py | 563 +++++++++ tests/memory/__init__.py | 1 + .../test_redis_client.py} | 2 +- tests/test_config.py | 117 ++ tests/test_gateway.py | 1080 ----------------- uv.lock | 20 +- 35 files changed, 2258 insertions(+), 1607 deletions(-) delete mode 100644 core/database.py delete mode 100644 core/redis.py create mode 100644 tests/api/__init__.py rename tests/{test_health_endpoints.py => api/test_health.py} (96%) rename tests/{ => api}/test_main.py (79%) create mode 100644 tests/core/test_logger.py create mode 100644 tests/gateway/__init__.py create mode 100644 tests/gateway/test_demux.py rename tests/{test_gateway_integration.py => gateway/test_integration.py} (90%) create mode 100644 tests/gateway/test_router.py rename tests/{ => gateway}/test_session_cleanup.py (97%) rename tests/{ => gateway}/test_session_cleanup_e2e.py (86%) rename tests/{ => gateway}/test_session_cleanup_integration.py (87%) create mode 100644 tests/gateway/test_session_manager.py create mode 100644 tests/gateway/test_ws_handler.py create mode 100644 tests/memory/__init__.py rename tests/{test_redis.py => memory/test_redis_client.py} (99%) create mode 100644 tests/test_config.py delete mode 100644 tests/test_gateway.py diff --git a/api/health.py b/api/health.py index 2a71e75..16e6558 100644 --- a/api/health.py +++ b/api/health.py @@ -10,8 +10,6 @@ from fastapi.responses import JSONResponse from core.app_state import AppState -from core.database import verify_database_connection -from core.redis import verify_redis_connection router = APIRouter(tags=["Health"]) @@ -29,8 +27,8 @@ async def health_check(request: Request) -> JSONResponse: state: AppState = request.app.state.app_state checks = { -
