Custom AST traversal replaces expensive `ast.walk()`** The original code uses `ast.walk()` which creates recursive stack frames for every AST node. The optimized version implements `iter_ast_calls()` - a manual iterative traversal that only visits `ast.Call` nodes using a single stack. This eliminates Python's recursion overhead and reduces the O(N) stack frame creation to a single stack operation. **2. Reduced attribute lookups in hot paths** - In `node_in_call_position()`: Uses `getattr()` with defaults to cache node attributes (`node_lineno`, `node_end_lineno`, etc.) instead of repeated `hasattr()` + attribute access - In `find_and_update_line_node()`: Hoists frequently-accessed object attributes (`fn_obj.qualified_name`, `self.mode`, etc.) to local variables before the loop - Pre-creates reusable AST nodes (`codeflash_loop_index`, `codeflash_cur`, `codeflash_con`) instead of recreating them in each iteration **Performance characteristics:** - **Small AST trees** (basic function calls): 5-28% faster due to reduced attribute lookups - **Large AST trees** (deeply nested calls): 18-26% faster due to more efficient traversal avoiding `ast.walk()` - **Large call position lists**: 26% faster due to optimized position checking with cached attributes The optimizations are most effective for complex test instrumentation scenarios with large AST trees or many call positions to check, which is typical in code analysis and transformation workflows. --- .../code_utils/instrument_existing_tests.py | 345 ++++++++++-------- 1 file changed, 189 insertions(+), 156 deletions(-) diff --git a/codeflash/code_utils/instrument_existing_tests.py b/codeflash/code_utils/instrument_existing_tests.py index 3057e923a..b1cc8c7be 100644 --- a/codeflash/code_utils/instrument_existing_tests.py +++ b/codeflash/code_utils/instrument_existing_tests.py @@ -32,23 +32,28 @@ def get_call_arguments(call_node: ast.Call) -> FunctionCallNodeArguments: def node_in_call_position(node: ast.AST, call_positions: list[CodePosition]) -> bool: - if isinstance(node, ast.Call) and hasattr(node, "lineno") and hasattr(node, "col_offset"): - for pos in call_positions: - if ( - pos.line_no is not None - and node.end_lineno is not None - and node.lineno <= pos.line_no <= node.end_lineno - ): - if pos.line_no == node.lineno and node.col_offset <= pos.col_no: - return True - if ( - pos.line_no == node.end_lineno - and node.end_col_offset is not None - and node.end_col_offset >= pos.col_no - ): - return True - if node.lineno < pos.line_no < node.end_lineno: - return True + # Profile: The most meaningful speedup here is to reduce attribute lookup and to localize call_positions if not empty. + # Small optimizations for tight loop: + if isinstance(node, ast.Call): + node_lineno = getattr(node, "lineno", None) + node_col_offset = getattr(node, "col_offset", None) + node_end_lineno = getattr(node, "end_lineno", None) + node_end_col_offset = getattr(node, "end_col_offset", None) + if node_lineno is not None and node_col_offset is not None and node_end_lineno is not None: + # Faster loop: reduce attribute lookups, use local variables for conditionals. + for pos in call_positions: + pos_line = pos.line_no + if pos_line is not None and node_lineno <= pos_line <= node_end_lineno: + if pos_line == node_lineno and node_col_offset <= pos.col_no: + return True + if ( + pos_line == node_end_lineno + and node_end_col_offset is not None + and node_end_col_offset >= pos.col_no + ): + return True + if node_lineno < pos_line < node_end_lineno: + return True return False @@ -84,28 +89,157 @@ def __init__( def find_and_update_line_node( self, test_node: ast.stmt, node_name: str, index: str, test_class_name: str | None = None ) -> Iterable[ast.stmt] | None: + # Major optimization: since ast.walk is *very* expensive for big trees and only checks for ast.Call, + # it's much more efficient to visit nodes manually.

This eliminates redundant type checking and attribute lookups. 3. **Direct base class method calls**: Changed `self.generic_visit(node)` to `ast.NodeVisitor.generic_visit(self, node)` to bypass Python's method resolution and attribute lookup on `self`, providing faster direct method invocation. 4. **Restructured control flow**: Combined the imported modules check with the function name lookup in a single conditional branch, reducing the number of separate `isinstance` calls from the original nested structure. **Performance Impact:** - The line profiler shows the most expensive line (`self.generic_visit(node)`) dropped from 9.86ms to 8.80ms (10.8% improvement) - The `generic_visit` method itself became 40% faster (5.04ms → 2.99ms) due to direct base class calls - Test results show consistent 8-17% improvements across various scenarios, with the largest gains (up to 23.6%) in complex cases involving multiple lookups **Best Use Cases:** The optimization is most effective for: - Large ASTs with many attribute nodes (as shown in the large-scale tests) - Codebases with extensive import analysis where `visit_Attribute` is called frequently - Scenarios with many non-matching attributes, where the fast-path optimizations provide the most benefit The changes preserve all original functionality while eliminating Python overhead in this performance-critical AST traversal code. --- codeflash/discovery/discover_unit_tests.py | 47 +++++++++++++--------- 1 file changed, 27 insertions(+), 20 deletions(-) diff --git a/codeflash/discovery/discover_unit_tests.py b/codeflash/discovery/discover_unit_tests.py index b0e141093..78aa2a1ec 100644 --- a/codeflash/discovery/discover_unit_tests.py +++ b/codeflash/discovery/discover_unit_tests.py @@ -223,14 +223,20 @@ def __init__(self, function_names_to_find: set[str]) -> None: self._dot_names: set[str] = set() self._dot_methods: dict[str, set[str]] = {} self._class_method_to_target: dict[tuple[str, str], str] = {} + + # Optimize prefix-roots and dot_methods construction + add_dot_methods = self._dot_methods.setdefault + add_prefix_roots = self._prefix_roots.setdefault + dot_names_add = self._dot_names.add + class_method_to_target = self._class_method_to_target for name in function_names_to_find: if "." in name: root, method = name.rsplit(".", 1) -

The optimized version inlines this logic directly, avoiding the base class method call entirely. 2. **More Frequent Early Exit Checks**: The new `_fast_generic_visit` checks `self.found_any_target_function` at multiple points during traversal (before processing lists and individual AST nodes), allowing faster short-circuiting when a target function is found. 3. **Optimized Attribute Access**: The optimization uses direct `getattr` calls and caches method lookups (`getattr(self, 'visit_' + item.__class__.__name__, None)`) to reduce repeated attribute resolution. **Performance Impact by Test Case:** - **Large-scale tests** show the biggest gains (27-35% faster) because they process many AST nodes where the traversal overhead compounds - **Basic tests** with fewer nodes show moderate improvements (9-20% faster) - **Edge cases** with complex nesting benefit from the more frequent early-exit checks The line profiler shows the optimization reduces time spent in `generic_visit` from 144.2ms to 107.9ms (25% improvement), with the overall `visit_Call` method improving from 287.5ms to 210.3ms. This optimization is particularly valuable for AST analysis tools that process large codebases, as the traversal overhead reduction scales with the size and complexity of the analyzed code. --- codeflash/discovery/discover_unit_tests.py | 32 +++++++++++++++++++++- 1 file changed, 31 insertions(+), 1 deletion(-) diff --git a/codeflash/discovery/discover_unit_tests.py b/codeflash/discovery/discover_unit_tests.py index 78aa2a1ec..290bfb485 100644 --- a/codeflash/discovery/discover_unit_tests.py +++ b/codeflash/discovery/discover_unit_tests.py @@ -449,7 +449,37 @@ def generic_visit(self, node: ast.AST) -> None: if self.found_any_target_function: return # Direct base call improves run speed (avoids extra method resolution) - ast.NodeVisitor.generic_visit(self, node) + self._fast_generic_visit(node) + + def _fast_generic_visit(self, node: ast.AST) -> None: + """Faster generic_visit: Inline traversal, avoiding method resolution overhead. + Short-circuits (returns) if found_any_target_function is True. + """ + # This logic is derived from ast.NodeVisitor.generic_visit, but with optimizations. + found_flag = self.found_any_target_function + # Micro-optimization: store fATF in local variable for quick repeated early exit + if found_flag: + return + for field in node._fields: + value = getattr(node, field, None) + if isinstance(value, list): + for item in value: + if self.found_any_target_function: + return + if isinstance(item, ast.AST): + meth = getattr(self, "visit_" + item.__class__.__name__, None) + if meth is not None: + meth(item) + else: + self._fast_generic_visit(item) + elif isinstance(value, ast.AST): + if self.found_any_target_function: + return + meth = getattr(self, "visit_" + value.__class__.__name__, None) + if meth is not None: + meth(value) + else: + self._fast_generic_visit(value) def analyze_imports_in_test_file(test_file_path: Path | str, target_functions: set[str]) -> bool: From ccf9bda651ac123c5447261f0ad1c71bf3f26d44 Mon Sep 17 00:00:00 2001 From: Codeflash Bot Date: Wed, 5 Nov 2025 01:30:14 -0800 Subject: [PATCH 11/16] linter fix --- codeflash/discovery/discover_unit_tests.py | 1 + 1 file changed, 1 insertion(+) diff --git a/codeflash/discovery/discover_unit_tests.py b/codeflash/discovery/discover_unit_tests.py index 290bfb485..ad67943f0 100644 --- a/codeflash/discovery/discover_unit_tests.py +++ b/codeflash/discovery/discover_unit_tests.py @@ -453,6 +453,7 @@ def generic_visit(self, node: ast.AST) -> None: def _fast_generic_visit(self, node: ast.AST) -> None: """Faster generic_visit: Inline traversal, avoiding method resolution overhead. + Short-circuits (returns) if found_any_target_function is True.

The optimized version uses a manual stack with `while` loop iteration, eliminating function call overhead and stack frame management costs. 2. **Faster method resolution**: Replaced `getattr(self, "visit_" + classname, None)` with `type(self).__dict__.get("visit_" + classname)`, which is significantly faster for method lookup. The class dictionary lookup avoids the more expensive attribute resolution pathway. 3. **Local variable caching**: Pre-cached frequently accessed attributes like `stack.append`, `stack.pop`, and `type(self).__dict__` into local variables to reduce repeated attribute lookups during the tight inner loop. **Why this leads to speedup:** - **Reduced function call overhead**: Each recursive call in the original version creates a new stack frame with associated setup/teardown costs. The iterative approach eliminates this entirely. - **Faster method resolution**: Dictionary `.get()` is ~2-3x faster than `getattr()` for method lookups, especially important since this happens for every AST node visited. - **Better cache locality**: The manual stack keeps traversal state in a more compact, cache-friendly format compared to Python's call stack. **Performance characteristics from test results:** The optimization shows variable performance depending on AST structure: - **Large nested trees**: 39.2% faster (deep recursion → iteration benefit is maximized) - **Early exit scenarios**: 57% faster on large trees (stack-based approach handles early termination more efficiently) - **Simple nodes**: Some overhead for very small cases due to setup costs, but still performs well on realistic workloads - **Complex traversals**: 14-24% faster on typical code structures with mixed node types This optimization is particularly valuable for AST analysis tools that process large codebases, where the cumulative effect of faster traversal becomes significant. --- codeflash/discovery/discover_unit_tests.py | 55 +++++++++++++--------- 1 file changed, 34 insertions(+), 21 deletions(-) diff --git a/codeflash/discovery/discover_unit_tests.py b/codeflash/discovery/discover_unit_tests.py index ad67943f0..368214184 100644 --- a/codeflash/discovery/discover_unit_tests.py +++ b/codeflash/discovery/discover_unit_tests.py @@ -457,30 +457,43 @@ def _fast_generic_visit(self, node: ast.AST) -> None: Short-circuits (returns) if found_any_target_function is True.
