From 683579fc13771d2c2d31877519ebbd254c7f0953 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 15 Nov 2025 19:44:06 +0000 Subject: [PATCH 1/4] Address technical debt: improve error handling and logging This commit addresses three critical technical debt items: 1. Add .env.example file - Created comprehensive environment variable documentation - Includes CENSUS_API_KEY setup instructions with signup URL - Helps with onboarding and configuration management 2. Fix empty except blocks with proper error handling - Added logging to previously silent error handlers in changelog.py - Added logging to network/parsing errors in probe_data_sources.py - Errors are now visible for debugging instead of being silently ignored - Added logging import to probe_data_sources.py 3. Replace print() with proper logging - Replaced all print() statements with appropriate logging levels - Added logging configuration to convert_to_pmtiles.py, download_graphs.py - Added logging import to h3utils.py - Errors use logging.error(), warnings use logging.warning(), info uses logging.info() - Improves debuggability and allows for log level control These improvements enhance code maintainability, debuggability, and user experience. --- .env.example | 10 ++++++++++ src/changelog.py | 9 +++++---- src/convert_to_pmtiles.py | 32 ++++++++++++++++++-------------- src/download_graphs.py | 9 +++++++-- src/h3utils.py | 7 ++++--- src/probe_data_sources.py | 9 +++++---- 6 files changed, 49 insertions(+), 27 deletions(-) create mode 100644 .env.example diff --git a/.env.example b/.env.example new file mode 100644 index 0000000..d31cf38 --- /dev/null +++ b/.env.example @@ -0,0 +1,10 @@ +# Environment Variables for ACCESS Project +# Copy this file to .env and fill in your actual values + +# Census API Key (Required for demographic analysis) +# Get your free API key at: https://api.census.gov/data/key_signup.html +# This key is used to download demographic data from the US Census Bureau +CENSUS_API_KEY=your_api_key_here + +# Note: The pipeline can run without this key, but the analysis step will be skipped +# If you have cached Census data, the API key is optional diff --git a/src/changelog.py b/src/changelog.py index fdc01e0..bf8f9ab 100755 --- a/src/changelog.py +++ b/src/changelog.py @@ -169,8 +169,9 @@ def create_notification( try: with open(notifications_file, 'r') as f: notifications = json.load(f) - except (json.JSONDecodeError, IOError): - pass + except (json.JSONDecodeError, IOError) as e: + logging.warning(f"Failed to load notifications file: {e}.

Library modules (h3utils.py): - Use logger = logging.getLogger(__name__) pattern - Removed basicConfig() which shouldn't be in imported modules - Changed logging.info() to logger.info() calls 2. Entry point scripts (convert_to_pmtiles.py, download_graphs.py): - Added explicit handlers=[logging.StreamHandler()] to basicConfig - Use logger = logging.getLogger(__name__) + logger.info() pattern - Consistent with run_pipeline.py and update_data_sources.py format 3. Added DEVELOPMENT.md documentation: - Clear guidelines for when to use basicConfig vs getLogger - Examples showing proper patterns for library vs entry scripts - Integration guidance for TQDM progress bars - Error handling best practices - Helps future developers use logging correctly These changes ensure: - No conflicts when modules are imported - Consistent logging format across the codebase - Proper integration with TQDM progress bars - Clear documentation for future contributors --- DEVELOPMENT.md | 119 ++++++++++++++++++++++++++++++++++++++ src/convert_to_pmtiles.py | 33 ++++++----- src/download_graphs.py | 15 +++-- src/h3utils.py | 8 ++- 4 files changed, 155 insertions(+), 20 deletions(-) create mode 100644 DEVELOPMENT.md diff --git a/DEVELOPMENT.md b/DEVELOPMENT.md new file mode 100644 index 0000000..8f2cc29 --- /dev/null +++ b/DEVELOPMENT.md @@ -0,0 +1,119 @@ +# Development Guide + +This document provides guidelines for contributors working on the ACCESS codebase. + +## Logging Best Practices + +This codebase uses Python's standard `logging` module.
