From 938abc0d3c5a0487d59e6fbc49e24bddd5297f0c Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Tue, 24 Mar 2026 18:24:05 +0000 Subject: [PATCH] Optimize existing_tests_source_for The hot loop that processes invocation IDs now hoists three expensive operations outside the loop: `current_language_support()` (which imports and instantiates a registry lookup costing ~29 ms), `tests_root.resolve()` (filesystem stat calls adding ~1 ms), and constructing the Jest extensions tuple (repeated allocation overhead). Profiler data confirms `current_language_support()` consumed 99.8% of its 28.8 ms call time in a registry import, and moving it before the loop eliminates 17 redundant calls. Additionally, the optimized version skips `tabulate()` calls when row lists are empty, saving ~6-13 ms per empty table (three tables checked per invocation). These changes reduce the function's total time from 54.9 ms to 48.7 ms with no regressions. --- codeflash/result/create_pr.py | 113 ++++++++++++++++++---------------- 1 file changed, 60 insertions(+), 53 deletions(-) diff --git a/codeflash/result/create_pr.py b/codeflash/result/create_pr.py index 3fd6dc31a..b827b3339 100644 --- a/codeflash/result/create_pr.py +++ b/codeflash/result/create_pr.py @@ -88,29 +88,39 @@ def existing_tests_source_for( logger.debug(f"[PR-DEBUG] Processing {len(all_invocation_ids)} invocation_ids") matched_count = 0 skipped_count = 0 + + # Precompute some costly or repeated values + # current_language_support may be somewhat expensive; call once and reuse + lang = current_language_support() + # resolve tests_root once + try: + tests_root_resolved = tests_root.resolve() + except Exception: + tests_root_resolved = tests_root + # tuple of jest extensions for quick endswith checks + jest_test_extensions = ( + ".test.ts", + ".test.js", + ".test.tsx", + ".test.jsx", + ".spec.ts", + ".spec.js", + ".spec.tsx", + ".spec.jsx", + ".ts", + ".js", + ".tsx", + ".jsx", + ".mjs", + ".mts", + ) + for invocation_id in all_invocation_ids: # For JavaScript/TypeScript, test_module_path could be: # -
