Stage 5: Complete SQLAlchemy 2.0 Migration - Final Stage by bokelley · Pull Request #319 · prebid/salesagent

bokelley · 2025-10-07T18:03:33Z

Summary

This PR completes the SQLAlchemy 2.0 migration for the entire codebase by migrating all remaining source files and test files.

What Changed

Source Files Migrated (93 patterns total)

src/core/ (23 patterns): context_manager, config_loader, auth_utils, strategy, audit_logger, database files
src/services/ (31 patterns): GAM inventory/orders services, push notifications, dynamic pricing, format metrics
src/adapters/ (31 patterns): All adapters including GAM (original, reporting, managers), mock, xandr
src/a2a_server/ (4 patterns): A2A server AdCP implementation
src/core/database/ (4 patterns): Database session helpers and documentation

Test Files Migrated (148 patterns total)

tests/integration/ (95+ patterns): All integration tests across 20+ files
tests/unit/ (18 patterns): Unit tests including session validation, workflow architecture
tests/utils/ (5 patterns): Database helpers and fixtures
tests/smoke/ (2 patterns): Smoke test critical paths
tests/manual/ (2 patterns): Manual GAM automation tests
tests/e2e/ (2 patterns): End-to-end test fixtures

Migration Patterns Applied

All code now uses SQLAlchemy 2.0 patterns:

# OLD (SQLAlchemy 1.x)
session.query(Model).filter_by(field=value).first()
session.query(Model).filter(condition).all()
session.query(Model).count()
session.query(Model).filter_by(field=value).delete()

# NEW (SQLAlchemy 2.0)
stmt = select(Model).filter_by(field=value)
result = session.scalars(stmt).first()

stmt = select(Model).where(condition)
results = session.scalars(stmt).all()

count = session.scalar(select(func.count()).select_from(Model))

session.execute(delete(Model).where(Model.field == value))

Verification

✅ 479 unit tests passing (0 failures)
✅ 124+ integration tests passing
✅ 0 remaining .query() patterns in src/ and tests/
✅ All imports properly updated (select, delete, func from sqlalchemy)
✅ All pre-commit hooks passing

Testing Notes

All unit tests pass completely
Integration tests pass (1 flaky test requires PostgreSQL on non-standard port - infrastructure issue, not migration bug)
All actual database queries verified to use SQLAlchemy 2.0 patterns
Mock objects in tests still use .query syntax - this is intentional and correct (mocking the old API)

🎉 This completes the SQLAlchemy 2.0 migration for the entire codebase!

Migrated 4 core files with 15 query patterns: - config_loader.py: 4 patterns (tenant lookups, subdomain/vhost resolution) - auth_utils.py: 5 patterns (principal/tenant auth lookups) - strategy.py: 5 patterns (strategy CRUD, simulation state management) - audit_logger.py: 2 patterns (tenant name lookups for notifications) All patterns converted from session.query() to select() + scalars(). Includes delete() pattern in strategy.py for reset() function.
