⚡️ Speed up function _is_unrequested_hidden_file_or_is_inside_unrequested_hidden_dir by 11%

[codeflash-ai]

📄 11% (0.11x) speedup for _is_unrequested_hidden_file_or_is_inside_unrequested_hidden_dir in src/datasets/data_files.py

⏱️ Runtime : 9.22 milliseconds → 8.30 milliseconds (best of 6 runs)

📝 Explanation and details

This optimization achieves an 11% runtime improvement by eliminating unnecessary memory allocations in a path-filtering function. The key changes are:

What Changed:

1. Replaced list comprehensions with counting loops: Instead of building two intermediate lists (hidden_directories_in_path and hidden_directories_in_pattern), the code now uses simple integer counters that increment as hidden parts are found.

2. Eliminated set allocations: The original code used set(part) == {"."} to check if a part consists only of dots. The optimized version uses part.strip(".") != "" instead, avoiding the overhead of creating a set object for every path component.

Why It's Faster:

• Reduced memory allocations: In Python, creating lists and sets has significant overhead. By counting directly, we avoid allocating memory for intermediate data structures that are only used to determine their length.
• Lower Python interpreter overhead: Integer increments are much cheaper than list append operations, which require bounds checking and potential memory reallocation.
• Faster character check: String operations like strip() are implemented in optimized C code and avoid the overhead of set creation, hashing, and comparison.

Performance Context:
Based on the function_references, this function is called from resolve_pattern() in a list comprehension that filters file paths during glob operations. This means it's invoked once per matched file when resolving data file patterns. In workflows that scan directories with many files (especially those with hidden files/directories like .git/ or .venv/), this optimization compounds:

• For 1,000 files checked: saves ~0.92ms
• The test results show consistent 10-25% speedups across various path structures, with the best gains (27-41%) on deeply nested hidden directories

Test Case Performance:
The optimization excels with:

• Paths with multiple hidden parts (27-41% faster for 50+ nested hidden directories)
• Alternating hidden/regular structures (16-17% faster)
• Unicode hidden directories (11% faster)
• All test patterns show improvement, indicating robust performance across diverse real-world scenarios
