• Misc: Update links in README.
• Misc: Fix mypy typing.

0.17.2 - 2024-04-24

Changed:

• DAG Constructor: list_to_dag and dict_to_dag does not rely on dataframe_to_dag as pandas dataframe operation is phased out.

Fixed:

• DAG Constructor: Handle cases where reserved keywords are part of attribute upon creation and throw error accordingly.
• [#224] Tree/DAG Constructor: Null checks to not interpret 0 as null, this affects dataframe_to_tree_by_relation, add_dataframe_to_tree_by_path, add_dataframe_to_tree_by_name, dataframe_to_tree, and dataframe_to_dag. This will also affect showing/printing of trees when attr_omit_null is set to True.

Changed

• Tree Constructor: add_dict_to_tree_by_name and add_dataframe_to_tree_by_name modifies tree in-place instead of returning new tree, and does not accept join_type as argument as pandas dataframe operation is phased out. If there are clashing attributes, only those that have values will be replaced. This might not be backwards-compatible!
• Tree Constructor: dataframe_to_tree no longer relies on add_dataframe_to_tree_by_path as it performs assertion checks twice. This leads to 5% improvement in timings for a tree with 10000 nodes, averaged across 10 runs.
• Misc: Abstract out assertion checks for empty dataframe and duplicate attribute.
• Misc: Abstract out logic for checking null and filtering attributes.
• Misc: Optimization in dictionary and dataframe operations.

Fixed

• Tree Constructor: dict_to_tree no longer uses dataframe operations, leading to 33% improvement in timings for a tree with 10000 nodes, averaged across 10 runs. The resulting data type of node follows the dictionary exactly, compared to the previous dataframe operations that may change the dtypes for certain columns. This might not be backwards-compatible!
• Tree Constructor: dataframe_to_tree_by_relation fix root node detection logic, ignore existing name column, ignore non-attribute columns, ignore null attribute columns.
• Tree Constructor: add_dataframe_to_tree_by_path ignore existing name column, ignore non-attribute columns, ignore null attribute columns.
• Tree Constructor: add_dataframe_to_tree_by_name ignore existing name column, ignore non-attribute columns, ignore null attribute columns.
• Tree Constructor: dataframe_to_tree ignore existing name column, ignore non-attribute columns, ignore null attribute columns.
