This eliminates repeated memory allocations. 2. **Memory view for zero-copy slicing**: The `memoryview(buf)` allows efficient slicing (`mv[:n]`) without copying data, reducing memory overhead when updating the hash with partial buffers. 3. **Direct `open()` with unbuffered I/O**: Using `open(path, "rb", buffering=0)` instead of `Path(path).open("rb")` avoids the Path object overhead and disables Python's internal buffering to prevent double-buffering since we're managing our own buffer. **Performance impact**: The line profiler shows the critical file opening operation dropped from 83.4% to 62.2% of total time, while the new buffer operations (`readinto`, `memoryview`) are very efficient. This optimization is particularly effective for medium to large files where the reduced memory allocation overhead compounds across multiple read operations. **Best use cases**: This optimization excels when computing hashes for files larger than the 8KB buffer size, where the memory allocation savings become significant, and when called frequently in batch operations. --- codeflash/discovery/discover_unit_tests.py | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/codeflash/discovery/discover_unit_tests.py b/codeflash/discovery/discover_unit_tests.py index 21e1b71f8..3fe74246f 100644 --- a/codeflash/discovery/discover_unit_tests.py +++ b/codeflash/discovery/discover_unit_tests.py @@ -160,12 +160,14 @@ def get_function_to_test_map_for_file( @staticmethod def compute_file_hash(path: str | Path) -> str: h = hashlib.sha256(usedforsecurity=False) -
