Upgrade SQLAlchemy v1 to v2 (Python 3.14 blocker)#3293
Conversation
SQLAlchemy v1 does not support Python 3.14, making this upgrade a blocker. Key changes: - Update setup.py pin from sqlalchemy>=1.4,<2 to sqlalchemy>=2,<3 - Replace removed engine.execute() with connection-based execution using conn.exec_driver_sql() inside a connection context manager - Add _ResultProxy wrapper to eagerly fetch results so they survive connection closure (maintains existing fetchone()/fetchall() API) - Replace LegacyRow (removed in v2) with Row in type annotations - Update test mocks that used spec=LegacyRow to use plain MagicMock() since Row in v2 has a different interface - Add 10 dedicated SQLAlchemy v2 compatibility tests Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
