From c317ff108501aef6ed78739d590870415d6f2c49 Mon Sep 17 00:00:00 2001 From: maziggy Date: Sat, 13 Dec 2025 09:57:04 +0100 Subject: [PATCH] 1. Pre-commit Hook Configuration (.pre-commit-config.yaml) - Ruff linter and formatter - Fast Python linter with auto-fix - Standard hooks - trailing whitespace, end-of-file, YAML/JSON checks, large file detection, merge conflict detection, debug statements, private key detection - Custom hook - Runs import shadowing tests before commit 2. Ruff Configuration (pyproject.toml) - Python 3.11+ target - 120 character line length - Checks: pycodestyle, Pyflakes, isort, flake8-bugbear, comprehensions, pyupgrade, unused arguments, simplify - Sensible ignores for FastAPI patterns (Depends, unused route args) 3. New Test Files backend/tests/unit/test_code_quality.py (5 tests) - Import shadowing detection using AST analysis - Catches the exact bug that broke archive creation - Tests all Python files in main, services, and routes backend/tests/unit/test_log_error_detection.py (13 tests) - MQTT message processing (status, xcam, AMS, HMS) - Print lifecycle (start to complete, failure handling) - Service imports verification - Edge cases (empty messages, unknown fields, null values) backend/tests/integration/test_print_lifecycle.py (6 tests) - Print start callback logic - Print complete callback logic - Timelapse tracking (same-message detection, completion callback) - Callback error handling - Import shadowing verification --- .pre-commit-config.yaml | 43 +++ .../tests/integration/test_print_lifecycle.py | 221 +++++++++++++ .../tests/unit/test_log_error_detection.py | 313 ++++++++++++++++++ pyproject.toml | 69 ++++ 4 files changed, 646 insertions(+) create mode 100644 .pre-commit-config.yaml create mode 100644 backend/tests/integration/test_print_lifecycle.py create mode 100644 backend/tests/unit/test_log_error_detection.py create mode 100644 pyproject.toml diff --git a/.pre-commit-config.yaml b/.pre-commit-config.yaml new file mode 100644 index 000000000..05d5512e7 --- /dev/null +++ b/.pre-commit-config.yaml @@ -0,0 +1,43 @@ +# Pre-commit hooks for BamBuddy +# Install with: pip install pre-commit && pre-commit install + +repos: + # Ruff - Fast Python linter and formatter + - repo: https://github.com/astral-sh/ruff-pre-commit + rev: v0.8.2 + hooks: + # Linter + - id: ruff + args: [--fix, --exit-non-zero-on-fix] + types_or: [python, pyi] + # Formatter + - id: ruff-format + types_or: [python, pyi] + + # Standard pre-commit hooks + - repo: https://github.com/pre-commit/pre-commit-hooks + rev: v5.0.0 + hooks: + - id: trailing-whitespace + exclude: ^static/ + - id: end-of-file-fixer + exclude: ^static/ + - id: check-yaml + - id: check-json + exclude: ^static/ + - id: check-added-large-files + args: ['--maxkb=1000'] + - id: check-merge-conflict + - id: debug-statements + - id: detect-private-key + + # Check for import shadowing (custom) + - repo: local + hooks: + - id: check-import-shadowing + name: Check for dangerous import shadowing + entry: python -m pytest backend/tests/unit/test_code_quality.py::TestImportShadowing -v --tb=short + language: system + pass_filenames: false + types: [python] + files: ^backend/app/ diff --git a/backend/tests/integration/test_print_lifecycle.py b/backend/tests/integration/test_print_lifecycle.py new file mode 100644 index 000000000..215a813f6 --- /dev/null +++ b/backend/tests/integration/test_print_lifecycle.py @@ -0,0 +1,221 @@ +""" +Integration tests for the full print lifecycle. + +These tests verify that: +1.
