…) (#106) * feat: postgresql task store * feat: postgresql task store * feat: postgresql task store * feat: postgresql task store * feat: postgresql task store * Update check-spelling metadata * feat: postgresql task store * Refactor TaskStore to be database-agnostic using SQLAlchemy This commit replaces the PostgreSQL-specific TaskStore with a generic `DatabaseTaskStore` that leverages SQLAlchemy for database interactions. This change allows your A2A server to support multiple database backends, including SQLite, PostgreSQL, and MySQL. Key changes include: - Definition of a SQLAlchemy model `TaskModel` for storing task data. - Implementation of `DatabaseTaskStore` that uses the `TaskStore` interface and SQLAlchemy for CRUD operations. - Update of example application configurations to use `DatabaseTaskStore` when a `DATABASE_URL` environment variable is provided, defaulting to `InMemoryTaskStore` otherwise. - Creation of parameterized unit tests for `DatabaseTaskStore`, designed to run against SQLite, PostgreSQL, and MySQL to ensure compatibility. - Removal of the old `PostgreSQLTaskStore` and its specific tests. - Addition of necessary dependencies: `sqlalchemy`, `aiosqlite`, `aiomysql`. The new implementation makes the task persistence layer more flexible and extensible, allowing you to choose a database backend that best suits your needs. * feat: postgresql task store * feat: postgresql task store * feat: postgresql task store * feat: postgresql task store * feat: postgresql task store * Update check-spelling metadata * feat: postgresql task store * Refactor TaskStore to be database-agnostic using SQLAlchemy This commit replaces the PostgreSQL-specific TaskStore with a generic `DatabaseTaskStore` that leverages SQLAlchemy for database interactions.

Key changes include: - Addition of optional dependencies in `pyproject.toml` for database drivers. - Updates to example applications to demonstrate installation and usage with different databases. - Refactoring of task management to utilize a generic `DatabaseTaskStore` for improved flexibility. - Enhancements to the README for clearer instructions on database support. These changes enhance the SDK's versatility, allowing users to choose their preferred database backend. * Add drivername, aiomysql, and DSNs to the list of expected words in the spelling action * GitHub Actions installs SQL dependencies for tests and database tests gracefully skip when SQLAlchemy isn't installed locally * feat(db): refactor database backend to be database-agnostic This allows users to choose their preferred database backend (PostgreSQL, MySQL, SQLite) while maintaining full compatibility and proper type safety. - Replace PostgreSQL-specific JSONB with generic JSON type in models - Implement SQLAlchemy 2.0 best practices with Mapped types and TypeDecorator - Add configurable table name support via create_task_model() factory - Updated metadata field mapping between Pydantic and SQLAlchemy using declared_attr - Add comprehensive tests for metadata field mapping including complex nested data - Update GitHub Actions to install SQL dependencies for tests - Add pytest.importorskip to gracefully skip database tests when SQLAlchemy not installed - Fix test_types.py to use 'id' instead of 'taskId' for JSON-RPC requests - Add automatic cleanup of SQLite file::memory: files after tests - Remove examples directory (moved to separate a2a-samples repo) - Update pyproject.toml to remove workspace members reference and add `nox` for testing * fix(models): correct variable name in TaskModel repr template * fix: use typing_extensions for override decorator for Python 3.10 compatibility The override decorator was added in Python 3.12. For compatibility with Python 3.10, we import it from typing_extensions when not available in the typing module. --------- Co-authored-by: MEUNIER Laurent <[email protected]> Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com> Co-authored-by: Zac <[email protected]> Co-authored-by: kthota-g <[email protected]>
