Summary

Major modernization of the Triage codebase, bringing it up to date with modern Python tooling and database drivers.

Issues Closed

Key Changes

Tooling Migration

  • uv for package management (replaces pip/setuptools)
  • loguru for logging (replaces stdlib logging)
  • typer for CLI (enhanced interface)
  • justfile for task running (replaces manage.py and tutorial.sh)
  • ruff for linting/formatting (replaces black/flake8)
  • Removed RQ/Redis dependencies
  • Removed deprecated postmodeling module and adjusttext dependency

Database Modernization (SQLAlchemy 2.0 + psycopg3)

  • Migrated from SQLAlchemy 1.x to 2.0 patterns
  • Upgraded from psycopg2 to psycopg3 driver
  • Fixed all deprecated engine.execute() calls to use connection context managers
  • Replaced Ohio library's pg_copy_from with pandas (psycopg3 compatible)
  • Converted copy_expert() to psycopg3 cursor.copy() API
  • Added explicit cast(Interval) for psycopg3 type handling
  • Fixed NaN → NULL conversion for sklearn metrics

Test Infrastructure

  • Migrated from testing.postgresql to pytest-postgresql>=6.0.0
  • Created comprehensive pytest fixtures in conftest.py
  • Replaced csvkit/csvsql dependency with pandas for test data loading
  • Fixed test isolation issues with factory session cleanup

CI/CD Updates

  • Updated GitHub workflows to use astral-sh/setup-uv@v4
  • Updated Python version from 3.9/3.10 to 3.12
  • Added PostgreSQL service container for tests
  • Replaced tox with direct pytest execution

DirtyDuck Tutorial

  • Modernized docker-compose.yml with healthchecks
  • Added justfile tutorial commands
  • Updated documentation

Test Status

Test Suite Status
collate_tests 57 passed
results_tests 6 passed
architect_tests 19 passed, 1 skipped
postmodeling_tests 8 passed, 2 skipped (deprecated tests removed)
catwalk/test_evaluation 11 passed (was 7 failed)

Note: Some other catwalk test files still need SQLAlchemy 2.0 migration (pre-existing).

Breaking Changes

  • Python 3.12+ required (was 3.9+)
  • Deprecated postmodeling module removed

Migration Notes

  • Requires uv for dependency management
  • Database connections now use psycopg3 (automatic via SQLAlchemy)
  • No changes to user-facing APIs

fix(tests): replace csvkit/csvsql with pandas for test data loading
3124358 
Remove external csvkit dependency from test_integration.py by using
pandas read_csv() and to_sql() instead of subprocess csvsql call.

This eliminates the need to install csvkit system-wide and makes the
test suite more self-contained.

fix(catwalk): NaN handling and Interval casting for psycopg3 compatib…
c8958fb 
…ility

- Convert NaN metric values to None before database storage
  (sklearn roc_auc_score returns NaN when all labels are same class)
- Add explicit Interval cast in needs_evaluations() for psycopg3
- Filter NaN values from trial_results in stochastic evaluation

These changes ensure metrics like roc_auc store NULL instead of 'NaN'
when they cannot be computed, matching the documented behavior.

ci: remove Docker PostgreSQL service
eaf151b 
pytest-postgresql creates its own temporary PostgreSQL instances using
system binaries, so no Docker service is needed. This also removes the
-x flag from pytest to let all tests run.

fix(tests): clean up factory session in db_engine fixture teardown
a3abb07 
The factory session (scoped_session) persists across tests at module level.
When a test calls init_engine(), the session gets bound to that test's database.
When pytest-postgresql drops the database between tests, the session still has
a connection to the (now dead) database. The next test calling init_engine()
triggers session.remove() which tries to rollback on the dead connection,
causing "psycopg.errors.AdminShutdown: terminating connection" errors.

Fix: Clean up the factory session in db_engine fixture teardown, BEFORE
the postgresql fixture drops the database. This ensures the session is
properly disconnected before the database disappears.
