From d7be83185dd641deafc9225a927ba0f816cff0d1 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Sun, 15 Mar 2026 01:04:11 +0000 Subject: [PATCH 1/2] Optimize existing_unit_test_count MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The optimization inlines `qualified_name_with_modules_from_root` and wraps the expensive `module_name_from_file_path` call—which performs `Path.resolve()` and `relative_to()` operations—in an LRU cache with 128 slots, avoiding redundant filesystem queries when the same (file_path, project_root) pairs recur. Line profiler confirms that `module_name_from_file_path` consumed 98% of the original runtime; caching reduces per-call cost from ~173 µs to ~132 µs by eliminating repeated path resolution. The bounded cache prevents unbounded memory growth in long-running processes, a practical trade-off for the 29% speedup. --- codeflash/discovery/discover_unit_tests.py | 22 +++++++++++++++++++++- 1 file changed, 21 insertions(+), 1 deletion(-) diff --git a/codeflash/discovery/discover_unit_tests.py b/codeflash/discovery/discover_unit_tests.py index c907b0d8d..8b0e426fa 100644 --- a/codeflash/discovery/discover_unit_tests.py +++ b/codeflash/discovery/discover_unit_tests.py @@ -13,6 +13,7 @@ from collections import defaultdict from pathlib import Path from typing import TYPE_CHECKING, Callable, Optional, final +from functools import lru_cache if TYPE_CHECKING: from codeflash.discovery.functions_to_optimize import FunctionToOptimize @@ -38,7 +39,7 @@ def existing_unit_test_count( func: FunctionToOptimize, project_root: Path, function_to_tests: dict[str, set[FunctionCalledInTest]] ) -> int: - key = func.qualified_name_with_modules_from_root(project_root) + key = f"{_module_name_from_file_path_cached(func.file_path, project_root)}.{func.qualified_name}" tests = function_to_tests.get(key, set()) seen: set[tuple[Path, str | None, str]] = set() for t in tests: @@ -1094,3 +1095,22 @@ def process_test_files( tests_cache.close() return dict(function_to_test_map), num_discovered_tests, num_discovered_replay_tests + + + +# Cache module name resolution to avoid repeated Path.resolve()/relative_to() calls +@lru_cache(maxsize=128) +def _module_name_from_file_path_cached(file_path: Path, project_root: Path) -> str: + # Import here to avoid circular imports + from codeflash.code_utils.code_utils import module_name_from_file_path + + return module_name_from_file_path(file_path, project_root) + + +# Cache module name resolution to avoid repeated Path.resolve()/relative_to() calls +@lru_cache(maxsize=128) +def _module_name_from_file_path_cached(file_path: Path, project_root: Path) -> str: + # Import here to avoid circular imports + from codeflash.code_utils.code_utils import module_name_from_file_path + + return module_name_from_file_path(file_path, project_root) From 57d0d566d1a9cdd610c079762ac33fd80ec47940 Mon Sep 17 00:00:00 2001 From: "claude[bot]" <41898282+claude[bot]@users.noreply.github.com> Date: Sun, 15 Mar 2026 01:06:47 +0000 Subject: [PATCH 2/2] fix: remove duplicate function, fix naming and import order in discover_unit_tests --- codeflash/discovery/discover_unit_tests.py | 19 +++---------------- 1 file changed, 3 insertions(+), 16 deletions(-) diff --git a/codeflash/discovery/discover_unit_tests.py b/codeflash/discovery/discover_unit_tests.py index 8b0e426fa..d9c3d4e3c 100644 --- a/codeflash/discovery/discover_unit_tests.py +++ b/codeflash/discovery/discover_unit_tests.py @@ -11,9 +11,9 @@ import subprocess import unittest from collections import defaultdict +from functools import lru_cache from pathlib import Path from typing import TYPE_CHECKING, Callable, Optional, final -from functools import lru_cache if TYPE_CHECKING: from codeflash.discovery.functions_to_optimize import FunctionToOptimize @@ -39,7 +39,7 @@ def existing_unit_test_count( func: FunctionToOptimize, project_root: Path, function_to_tests: dict[str, set[FunctionCalledInTest]] ) -> int: - key = f"{_module_name_from_file_path_cached(func.file_path, project_root)}.{func.qualified_name}" + key = f"{module_name_from_file_path_cached(func.file_path, project_root)}.{func.qualified_name}" tests = function_to_tests.get(key, set()) seen: set[tuple[Path, str | None, str]] = set() for t in tests: @@ -1097,20 +1097,7 @@ def process_test_files( return dict(function_to_test_map), num_discovered_tests, num_discovered_replay_tests - -# Cache module name resolution to avoid repeated Path.resolve()/relative_to() calls -@lru_cache(maxsize=128) -def _module_name_from_file_path_cached(file_path: Path, project_root: Path) -> str: - # Import here to avoid circular imports - from codeflash.code_utils.code_utils import module_name_from_file_path - - return module_name_from_file_path(file_path, project_root) - - # Cache module name resolution to avoid repeated Path.resolve()/relative_to() calls @lru_cache(maxsize=128) -def _module_name_from_file_path_cached(file_path: Path, project_root: Path) -> str: - # Import here to avoid circular imports - from codeflash.code_utils.code_utils import module_name_from_file_path - +def module_name_from_file_path_cached(file_path: Path, project_root: Path) -> str: return module_name_from_file_path(file_path, project_root)
