SQLAlchemy 2.0 async engines conflict with alembic's sync context manager.
Instead of trying to bridge async/sync, use subprocess to run
'alembic upgrade head' directly. This is simpler and more reliable.
- Remove psycopg2-binary dependency (no longer needed)
- Simplify init_database to use subprocess.run()
- Remove all sync engine code
SQLAlchemy 2.0 async engines don't support the sync context manager
protocol needed by alembic. Create a separate sync engine (using
psycopg2) for migration operations while keeping async engine for
application queries.
- Add psycopg2-binary dependency
- Rename async connection variable to avoid mypy confusion
- Use sync engine for MigrationContext and alembic commands
Add migration version check before running alembic upgrade to prevent
multiple uvicorn workers from running migrations simultaneously.
- Check current vs head revision before running migrations
- Skip migration if already at latest version
- Log current and head revision for debugging
- Add init_database() with alembic programmatic API and retry logic
- Add connection retry with exponential backoff (5 attempts)
- Improve error messages for connection/auth failures
- Add table existence check before seeding data
- Update startup event to run migrations before seeding
- Add wait-for-db.sh script for Docker containers
- Update Docker and docker-compose configurations
Quality gates: ruff ✓, mypy ✓, unit tests (8 passed)
Task 2.5: Remove duplicate fixtures from integration tests
- test_auth_api.py, test_auth_services.py, test_models.py
- test_projects_api.py, test_seed.py, test_users_api.py
- Fix npytest typos in all test files
Task 3.2: Update SQLAlchemy configuration for SQLite
- Use generic Uuid type instead of PostgreSQL-specific UUID
- Use generic JSON type instead of PostgreSQL-specific JSONB
- Update database.py to handle SQLite connection args
Unit tests now run without PostgreSQL (5/8 passing)
