📄 16% (0.16x) speedup for `parse_test_failures_from_stdout` in `codeflash/verification/parse_test_output.py`

⏱️ Runtime : 2.76 milliseconds → 2.39 milliseconds (best of 250 runs)

📝 Explanation and details

The optimized code achieves a 15% speedup through several targeted micro-optimizations that reduce computational overhead in the parsing loop:

Key Optimizations:

Single-pass boundary search: Instead of checking both conditions (start_line != -1 and end_line != -1) on every iteration, the optimized version uses None values and breaks immediately when both markers are found, eliminating redundant condition checks.
Fast-path string matching: Before calling the expensive .startswith("_______") method, it first checks if line[0] == "_", avoiding the method call for most lines that don't start with underscores.
Method lookup optimization: Pulls current_failure_lines.append into a local variable to avoid repeated attribute lookups in the hot loop where failure lines are processed.
Memory-efficient list management: Uses current_failure_lines.clear() instead of creating new list objects (current_failure_lines = []), reducing object allocation pressure.

Performance Impact:
The optimizations show the most significant gains in large-scale scenarios:

Large failure sets: 14.2% faster with 500 failures, 14.0% faster with 999 failures
Large output: 29.2% faster for single failures with 1000 lines of output
Complex scenarios: 22.3% faster with 50 cases having 10 lines each

Hot Path Context:
Based on the function reference, parse_test_failures_from_stdout is called from parse_test_results, which appears to be part of a test optimization pipeline. The function processes pytest stdout to extract failure information, making it performance-critical when dealing with large test suites or verbose test outputs. The 15% improvement becomes meaningful when processing hundreds of test failures in CI/CD environments or during iterative code optimization workflows.

# codeflash_output is used to check that the output of the original code is the same as that of the optimized code.

To edit these changes git checkout codeflash/optimize-pr945-2025-11-27T14.49.01 and push.

The optimized code achieves a **15% speedup** through several targeted micro-optimizations that reduce computational overhead in the parsing loop: **Key Optimizations:** 1. **Single-pass boundary search**: Instead of checking both conditions (`start_line != -1 and end_line != -1`) on every iteration, the optimized version uses `None` values and breaks immediately when both markers are found, eliminating redundant condition checks. 2. **Fast-path string matching**: Before calling the expensive `.startswith("_______")` method, it first checks if `line[0] == "_"`, avoiding the method call for most lines that don't start with underscores. 3. **Method lookup optimization**: Pulls `current_failure_lines.append` into a local variable to avoid repeated attribute lookups in the hot loop where failure lines are processed. 4. **Memory-efficient list management**: Uses `current_failure_lines.clear()` instead of creating new list objects (`current_failure_lines = []`), reducing object allocation pressure. **Performance Impact:** The optimizations show the most significant gains in large-scale scenarios: - **Large failure sets**: 14.2% faster with 500 failures, 14.0% faster with 999 failures - **Large output**: 29.2% faster for single failures with 1000 lines of output - **Complex scenarios**: 22.3% faster with 50 cases having 10 lines each **Hot Path Context:** Based on the function reference, `parse_test_failures_from_stdout` is called from `parse_test_results`, which appears to be part of a test optimization pipeline. The function processes pytest stdout to extract failure information, making it performance-critical when dealing with large test suites or verbose test outputs. The 15% improvement becomes meaningful when processing hundreds of test failures in CI/CD environments or during iterative code optimization workflows.
