From ac861162c23c0c3a3bb80433734d5676f2750dea Mon Sep 17 00:00:00 2001 From: Zeba Fatma Khan Date: Tue, 23 Dec 2025 23:48:58 +0530 Subject: [PATCH] Fix Pipfile parsing crashes with inline table dependencies in libyear metrics The libyear dependency metrics collection would crash when processing Pipfiles with inline table (dict) dependency specifications. The code assumed all dependency values were strings, but Pipfile format allows dicts for complex specifications like extras, markers, and path dependencies. This commit: - Adds normalize_pipfile_version() to safely handle all Pipfile formats - Adds defensive type checks before string operations in downstream functions - Implements Pipfile.lock preference over Pipfile (more reliable) - Filters unsupported formats (path, editable) with debug logging - Adds 26 comprehensive unit tests - Includes reproduction script for verification Changes are backward compatible and use defensive programming to prevent future crashes. Valid dependencies continue to be processed; only unsupported formats (path, editable) are skipped with appropriate logging.

- added Pipfile.lock preference logic (lines 30-71) + +## PR Checklist + +Before submitting the PR, verify: + +- [ ] Reproduction script passes: `python scripts/reproduce_issue_3430.py` +- [ ] Unit tests pass: `pytest tests/test_tasks/test_libyear_dependency_metrics.py` +- [ ] No existing tests broken: `pytest tests/test_tasks/` +- [ ] Manual testing with real Pipfiles works +- [ ] Debug logs appear when dependencies are skipped +- [ ] Pipfile.lock is preferred over Pipfile when both exist + +## Additional Notes + +### Why Pipfile.lock is Preferred +The fix also adds logic to prefer `Pipfile.lock` over `Pipfile`: +- Pipfile.lock uses JSON format (more reliable to parse) +- Has exact pinned versions (deterministic) +- Avoids the inline table issues entirely + +### Supported Dependency Formats + +| Format | Example | Handled | +|--------|---------|---------| +| String | `">=2.0"` | ✅ Parsed | +| Dict w/ version | `{version = ">=2.0"}` | ✅ Extracted | +| Git | `{git = "url", ref = "main"}` | ✅ Converted | +| Path | `{path = "./local"}` | ⚠️ Skipped | +| Editable | `{editable = true}` | ⚠️ Skipped | +| Extras only | `{extras = ["security"]}` | ⚠️ Skipped | + +## Troubleshooting + +### Import Errors +``` +ModuleNotFoundError: No module named 'augur' +``` +**Solution**: Make sure you're in the Augur root directory and Augur is installed: +```powershell +cd E:\zeba\augur +pip install -e . +``` + +### Test File Not Found +``` +Test Pipfile not found at: tests/test_data/issue_3430_test_Pipfile +``` +**Solution**: The script will create an in-memory test Pipfile, or you can ensure the file exists. + +### Python Not Found +```powershell +python : The term 'python' is not recognized +``` +**Solution**: Try `python3` or `py -3` instead. + +## Contact +
