From 8d5ba833c3796235caf5047cbea3191f2d3b5ebc Mon Sep 17 00:00:00 2001 From: Damian O'Neill Date: Mon, 22 Sep 2025 18:12:27 +0100 Subject: [PATCH 1/8] feat: add Redis session support for scalable distributed memory - Add RedisSession class with full Session protocol implementation - Support Redis URL connection strings and direct client injection - Include TTL (time-to-live) support for automatic session expiration - Add key prefixes for multi-tenancy and namespace isolation - Implement atomic operations using Redis pipelines for data integrity - Add comprehensive test suite with in-memory fakeredis support - Include detailed example demonstrating Redis session features - Update documentation with Redis session reference - Add redis extra dependency group for easy installation The RedisSession enables production-grade, distributed session memory that scales across multiple application instances while maintaining full compatibility with the existing Session interface. --- .gitignore | 3 + README.md | 11 +- docs/ref/extensions/memory/redis_session.md | 3 + examples/basic/dynamic_system_prompt.py | 1 + examples/basic/tools.py | 1 + examples/memory/redis_session_example.py | 170 +++++++ pyproject.toml | 2 + src/agents/extensions/memory/__init__.py | 12 + src/agents/extensions/memory/redis_session.py | 250 ++++++++++ tests/extensions/memory/test_redis_session.py | 452 ++++++++++++++++++ uv.lock | 43 +- 11 files changed, 946 insertions(+), 2 deletions(-) create mode 100644 docs/ref/extensions/memory/redis_session.md create mode 100644 examples/memory/redis_session_example.py create mode 100644 src/agents/extensions/memory/redis_session.py create mode 100644 tests/extensions/memory/test_redis_session.py diff --git a/.gitignore b/.gitignore index c0c4b3254..0dc73ccd2 100644 --- a/.gitignore +++ b/.gitignore @@ -144,3 +144,6 @@ cython_debug/ # PyPI configuration file .pypirc .aider* + +# Redis database files +dump.rdb diff --git a/README.md b/README.md index 6e4c16d19..90303619a 100644 --- a/README.md +++ b/README.md @@ -31,6 +31,8 @@ pip install openai-agents For voice support, install with the optional `voice` group: `pip install 'openai-agents[voice]'`. +For Redis session support, install with the optional `redis` group: `pip install 'openai-agents[redis]'`. + ### uv If you're familiar with [uv](https://docs.astral.sh/uv/), using the tool would be even similar: @@ -42,6 +44,8 @@ uv add openai-agents For voice support, install with the optional `voice` group: `uv add 'openai-agents[voice]'`. +For Redis session support, install with the optional `redis` group: `uv add 'openai-agents[redis]'`. + ## Hello world example ```python @@ -211,8 +215,13 @@ print(result.final_output) # "Approximately 39 million" ```python from agents import Agent, Runner, SQLiteSession -# Custom SQLite database file +# SQLite -

decode_responses compatibility - Add Redis client ownership tracking with _owns_client attribute - Implement conditional close() method to prevent closing shared clients - Fix decode_responses compatibility in get_items() and pop_item() methods - Handle both bytes (default) and string (decode_responses=True) Redis responses - Add comprehensive test coverage for client ownership scenarios - Add tests for decode_responses=True client compatibility with both fakeredis and real Redis - Ensure proper resource management and thread-safe operations - Maintain backward compatibility while fixing production edge cases This addresses Redis client lifecycle management issues and ensures compatibility with common Redis client configurations used in production. ---
