Walkthrough

The updates in the fastkml library primarily enhance the KML parsing functionality. The class_from_string method has been renamed to parse, shifting its focus from string input to directly accepting KML files. This change improves usability and flexibility in handling KML data. Additionally, the test suite has been expanded with new classes and methods to ensure robust validation of the parsing process across various scenarios.

Changes

Files Change Summary
fastkml/kml.py Renamed class_from_string to parse, changing input from a string to a file (supports Path, str, IO). Updated docstring and parsing logic.
tests/kml_test.py Added TestParseKML and TestLxmlParseKML classes with several new tests to validate KML parsing. Modified existing tests for enhanced file handling.

Poem

🐰 In the meadow where KMLs play,
A new parsing method brightens the day.
From strings to files, oh what a delight,
Parsing with ease, everything feels right!
Hopping with joy, the changes are here,
For KML adventures, let’s give a cheer! 🌼✨

PR Summary

  • Integration of new Libraries
    Imported pathlib and IO libraries to enhance file handling capabilities in the fastkml/kml.py file.

  • Renamed Key Method
    The class_from_string method has been renamed to parse. This provides more clarity on what the method is actually doing in the fastkml/kml.py file.

  • Method Transition
    Shift from config.etree.fromstring to config.etree.parse in the parse method. This allows our program to read XML data directly from files or open file streams in the fastkml/kml.py file.

  • Root Extraction
    The root element of the parsed XML tree is now being extracted in the parse method. Having direct access to the root element enhances the parsing performance in the fastkml/kml.py file.

  • Additional Test Methods
    New test methods have been included: test_parse_kml, test_parse_kml_filename, and test_parse_kml_fileobject in the kml_test.py file to increase test coverage and assure the new parse function works correctly.

  • Modified Test Method
    The test_kml function now compares two KML objects based on their to_string method in the kml_test.py file. This change provides a more efficient way to match KML objects.

  • Additional Edge-Case Handling
    A new test method test_from_string_with_unbound_prefix has been added to kml_test.py. This method verifies that the new parsing function can process XML strings even if they include an undefined prefix.

The exception handling for TypeError seems redundant. If the initial parsing fails due to a TypeError, the same parsing method is called again without any changes or additional error handling, which could lead to unhandled exceptions if the error persists.

suggestion (performance): Consider performance implications for large files

The method now parses the entire file before extracting the root element. For very large files, this could have memory usage implications. Consider adding a note about this in the docstring, or investigate if there's a more memory-efficient way to parse large KML files.

    ✨ CI feedback usage guide:

    The CI feedback tool (/checks) automatically triggers when a PR has a failed check.
    The tool analyzes the failed checks and provides several feedbacks:

    • Failed stage
    • Failed test name
    • Failure summary
    • Relevant error logs

    In addition to being automatically triggered, the tool can also be invoked manually by commenting on a PR:

    /checks "https://github.com/{repo_name}/actions/runs/{run_number}/job/{job_number}"
    

    where {repo_name} is the name of the repository, {run_number} is the run number of the failed check, and {job_number} is the job number of the failed check.

    Configuration options

    • enable_auto_checks_feedback - if set to true, the tool will automatically provide feedback when a check is failed. Default is true.
    • excluded_checks_list - a list of checks to exclude from the feedback, for example: ["check1", "check2"]. Default is an empty list.
    • enable_help_text - if set to true, the tool will provide a help message with the feedback. Default is true.
    • persistent_comment - if set to true, the tool will overwrite a previous checks comment with the new feedback. Default is true.
    • final_update_message - if persistent_comment is true and updating a previous checks message, the tool will also create a new message: "Persistent checks updated to latest commit". Default is true.

    See more information about the checks tool in the docs.
