From 29aecd992272d92c9f6dff298845237d014a7a1e Mon Sep 17 00:00:00 2001 From: Akshay Date: Sun, 20 Jul 2025 12:56:20 +0700 Subject: [PATCH 01/10] feat: add storage backend support and CI/CD workflows - Introduced configurable storage backends: memory, Redis, and Vault, with detailed configuration options in `config.example.yaml`. - Implemented a `StorageManager` to handle storage backend initialization and management. - Added Docker Compose file for easy deployment with Redis storage. - Created GitHub Actions workflows for linting, testing, and Docker image publishing. - Updated documentation to include storage backend details and usage examples. - Enhanced tests for storage functionality and configuration validation. --- .github/workflows/docker-publish.yml | 56 +++ .github/workflows/lint.yml | 45 ++ .github/workflows/test.yml | 130 ++++++ .gitignore | 5 +- ARCHITECTURE.md | 340 +++----------- CLAUDE.md | 415 +++++++++++++++++- README.md | 265 ++++++++--- config.example.yaml | 64 ++- demo/fastmcp_server.py | 15 +- docker-compose.yml | 78 ++++ requirements-all.txt | 13 + requirements-dev.txt | 34 ++ requirements-redis.txt | 9 + requirements-vault.txt | 6 + requirements.txt | 20 +- src/auth/client_registry.py | 49 ++- src/auth/oauth_server.py | 134 +++--- src/auth/token_manager.py | 176 ++++---- src/config/config.py | 119 +++++ src/gateway.py | 168 ++++++- src/storage/__init__.py | 20 + src/storage/base.py | 199 +++++++++ src/storage/manager.py | 141 ++++++ src/storage/memory.py | 133 ++++++ src/storage/redis.py | 268 +++++++++++ src/storage/vault.py | 365 +++++++++++++++ tests/auth/test_client_registry.py | 152 ++++--- tests/auth/test_multi_provider_constraints.py | 69 +-- tests/auth/test_oauth_server.py | 60 ++- tests/auth/test_provider_manager.py | 18 +- tests/auth/test_single_provider.py | 117 +++-- tests/auth/test_token_manager.py | 100 +++-- tests/conftest.py | 96 +++- tests/gateway/test_middleware.py | 63 +-- tests/gateway/test_provider_determination.py | 58 ++- tests/integration/test_resilient_oauth.py | 192 +++++--- tests/storage/__init__.py | 1 + tests/storage/fakes.py | 298 +++++++++++++ tests/storage/test_basic_functionality.py | 177 ++++++++ tests/storage/test_memory_storage.py | 276 ++++++++++++ tests/storage/test_redis_storage.py | 301 +++++++++++++ .../storage/test_storage_config_validation.py | 176 ++++++++ tests/storage/test_storage_manager.py | 390 ++++++++++++++++ tests/storage/test_vault_storage.py | 381 ++++++++++++++++ 44 files changed, 5280 insertions(+), 912 deletions(-) create mode 100644 .github/workflows/docker-publish.yml create mode 100644 .github/workflows/lint.yml create mode 100644 .github/workflows/test.yml create mode 100644 docker-compose.yml create mode 100644 requirements-all.txt create mode 100644 requirements-dev.txt create mode 100644 requirements-redis.txt create mode 100644 requirements-vault.txt create mode 100644 src/storage/__init__.py create mode 100644 src/storage/base.py create mode 100644 src/storage/manager.py create mode 100644 src/storage/memory.py create mode 100644 src/storage/redis.py create mode 100644 src/storage/vault.py create mode 100644 tests/storage/__init__.py create mode 100644 tests/storage/fakes.py create mode 100644 tests/storage/test_basic_functionality.py create mode 100644 tests/storage/test_memory_storage.py create mode 100644 tests/storage/test_redis_storage.py create mode 100644 tests/storage/test_storage_config_validation.py create mode 100644 tests/storage/test_storage_manager.py create mode 100644 tests/storage/test_vault_storage.py diff --git a/.github/workflows/docker-publish.yml b/.github/workflows/docker-publish.yml new file mode 100644 index 0000000..82f7e49 --- /dev/null +++ b/.github/workflows/docker-publish.yml @@ -0,0 +1,56 @@ +name: Docker Publish + +on: + push: + branches: [ main ] + tags: [ 'v*' ] + workflow_dispatch: + +env: + REGISTRY: ghcr.io + IMAGE_NAME: ${{ github.repository }} + +jobs: + build-and-publish: + runs-on: ubuntu-latest + permissions: + contents: read + packages: write + + steps: + -
