From fa00422feaf0eb526606fcf434d11c3e1973beea Mon Sep 17 00:00:00 2001 From: Kevin Turcios Date: Mon, 16 Feb 2026 13:34:07 -0500 Subject: [PATCH 01/14] refactor: simplify and deduplicate code_context_extractor Consolidate three enricher functions (get_imported_class_definitions, get_external_base_class_inits, get_external_class_inits) into a single enrich_testgen_context that parses code context once. Extract shared helpers, unify prune_cst variants, deduplicate loop bodies, and remove dead UsedNameCollector class. --- .gitignore | 2 + codeflash/code_utils/config_consts.py | 4 +- codeflash/context/code_context_extractor.py | 1136 +++++++------------ codeflash/languages/current.py | 2 +- tests/test_code_context_extractor.py | 619 ++-------- 5 files changed, 469 insertions(+), 1294 deletions(-) diff --git a/.gitignore b/.gitignore index b80ab3816..bf2a23e4d 100644 --- a/.gitignore +++ b/.gitignore @@ -268,3 +268,5 @@ tessl.json # Tessl auto-generates AGENTS.md on install; ignore to avoid cluttering git status AGENTS.md +.serena/ +.codeflash/ diff --git a/codeflash/code_utils/config_consts.py b/codeflash/code_utils/config_consts.py index e344fad8a..b84a136d8 100644 --- a/codeflash/code_utils/config_consts.py +++ b/codeflash/code_utils/config_consts.py @@ -4,8 +4,8 @@ from typing import Any, Union MAX_TEST_RUN_ITERATIONS = 5 -OPTIMIZATION_CONTEXT_TOKEN_LIMIT = 16000 -TESTGEN_CONTEXT_TOKEN_LIMIT = 16000 +OPTIMIZATION_CONTEXT_TOKEN_LIMIT = 48000 +TESTGEN_CONTEXT_TOKEN_LIMIT = 48000 INDIVIDUAL_TESTCASE_TIMEOUT = 15 MAX_FUNCTION_TEST_SECONDS = 60 MIN_IMPROVEMENT_THRESHOLD = 0.05 diff --git a/codeflash/context/code_context_extractor.py b/codeflash/context/code_context_extractor.py index a77cc29e6..0220a642d 100644 --- a/codeflash/context/code_context_extractor.py +++ b/codeflash/context/code_context_extractor.py @@ -6,7 +6,7 @@ from collections import defaultdict from itertools import chain from pathlib import Path -from typing import TYPE_CHECKING, cast +from typing import TYPE_CHECKING import libcst as cst @@ -34,47 +34,41 @@ from codeflash.optimization.function_context import belongs_to_function_qualified if TYPE_CHECKING: + from collections.abc import Callable + from jedi.api.classes import Name -

This includes unnecessary nodes like expressions, literals, and operators that can never contain `ImportFrom` statements. The optimized version implements a custom `collect_imports()` function that: 1. **Only traverses module body and control flow structures** where imports can legally appear (function/class definitions, if/while/for blocks, try/except) 2. **Skips irrelevant AST nodes** like expressions, literals, and operators entirely 3. **Recursively processes nested bodies** (body, orelse, finalbody, handlers) in a depth-first manner **Why This Works:** In Python, `from X import Y` statements can only appear: - At module level - Inside function/class definitions - Within control flow blocks (if/while/for/try) By checking `isinstance()` for only these container node types and recursively descending into their body attributes, we avoid traversing the entire AST subtree for each construct. This dramatically reduces the number of nodes visited while maintaining correctness. **Test Case Performance:** The optimization excels across all scales: - **Small imports** (single statements): 60-77% faster - **Large import lists** (100-500 items): 74-104% faster - **Many code blocks** (500-1000 lines): 70-77% faster - **Mixed code/imports** at scale: 70% faster The performance gain is particularly pronounced when the AST contains large amounts of non-import code (functions, classes, expressions), as shown by the `test_mixed_imports_and_code_large_scale` case improving from 9.31ms to 5.45ms (70.8% faster). **Impact on Workloads:** Given the function_references show this is used in code context extraction benchmarks, this optimization will significantly speed up any workflow that analyzes Python imports from large codebases or performs repeated import analysis during development workflows. --- .../python/context/code_context_extractor.py | 31 +++++++++++++++---- 1 file changed, 25 insertions(+), 6 deletions(-) diff --git a/codeflash/languages/python/context/code_context_extractor.py b/codeflash/languages/python/context/code_context_extractor.py index 9f904efbc..173dc8021 100644 --- a/codeflash/languages/python/context/code_context_extractor.py +++ b/codeflash/languages/python/context/code_context_extractor.py @@ -553,12 +553,31 @@ def _parse_and_collect_imports(code_context: CodeStringsMarkdown) -> tuple[ast.M except SyntaxError: return None imported_names: dict[str, str] = {} -

For a typical Python module, this means checking thousands of irrelevant nodes. The optimized version uses a stack-based approach that only descends into structural nodes (ClassDef, FunctionDef, If, For, While, With, Try blocks) where classes can actually be defined. This dramatically reduces the number of nodes visited and `isinstance()` checks performed. **Why This Matters:** From the test results, we see consistent 200-700% speedups across all scenarios: - Empty modules: 579% faster (5.37μs → 791ns) - minimal traversal overhead - Simple cases: 200-400% faster - fewer nodes to check - Complex nested structures: 405% faster (37.2μs → 7.37μs) - targeted descent pays off - Large modules (500 classes): 280% faster (869μs → 228μs) - scales better - Mixed workloads: 558% faster (799μs → 121μs) - avoids non-class nodes **Impact on Workloads:** Based on the function references showing this is called from `build_testgen_context`, this optimization benefits test generation workflows that analyze Python code structure. Since class extraction is likely performed repeatedly during code analysis, the 4x speedup directly improves overall test generation throughput. The optimization is particularly effective for large codebases with many classes and complex nesting patterns, as demonstrated by the benchmark results. --- .../python/context/code_context_extractor.py | 23 ++++++++++++++++++- 1 file changed, 22 insertions(+), 1 deletion(-) diff --git a/codeflash/languages/python/context/code_context_extractor.py b/codeflash/languages/python/context/code_context_extractor.py index 9f904efbc..b710f044d 100644 --- a/codeflash/languages/python/context/code_context_extractor.py +++ b/codeflash/languages/python/context/code_context_extractor.py @@ -563,7 +563,28 @@ def _parse_and_collect_imports(code_context: CodeStringsMarkdown) -> tuple[ast.M def collect_existing_class_names(tree: ast.Module) -> set[str]: - return {node.name for node in ast.walk(tree) if isinstance(node, ast.ClassDef)} + class_names = set() + stack = list(tree.body) + + while stack: + node = stack.pop() + if isinstance(node, ast.ClassDef): + class_names.add(node.name) + stack.extend(node.body) + elif isinstance(node, ast.FunctionDef): + stack.extend(node.body) + elif isinstance(node, (ast.If, ast.For, ast.While, ast.With)): + stack.extend(node.body) + if hasattr(node, 'orelse'): + stack.extend(node.orelse) + elif isinstance(node, ast.Try): + stack.extend(node.body) + stack.extend(node.orelse) + stack.extend(node.finalbody) + for handler in node.handlers: + stack.extend(handler.body) + + return class_names def enrich_testgen_context(code_context: CodeStringsMarkdown, project_root_path: Path) -> CodeStringsMarkdown: From 69d32681f786ae3b7c6fb615dfb34d98cbfbe91c Mon Sep 17 00:00:00 2001 From: "claude[bot]" <41898282+claude[bot]@users.noreply.github.com> Date: Mon, 16 Feb 2026 20:55:52 +0000 Subject: [PATCH 10/14] style: auto-fix linting issues --- .../languages/python/context/code_context_extractor.py | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/codeflash/languages/python/context/code_context_extractor.py b/codeflash/languages/python/context/code_context_extractor.py index b710f044d..a07ba918d 100644 --- a/codeflash/languages/python/context/code_context_extractor.py +++ b/codeflash/languages/python/context/code_context_extractor.py @@ -565,7 +565,7 @@ def _parse_and_collect_imports(code_context: CodeStringsMarkdown) -> tuple[ast.M def collect_existing_class_names(tree: ast.Module) -> set[str]: class_names = set() stack = list(tree.body) - + while stack: node = stack.pop() if isinstance(node, ast.ClassDef): @@ -575,7 +575,7 @@ def collect_existing_class_names(tree: ast.Module) -> set[str]: stack.extend(node.body) elif isinstance(node, (ast.If, ast.For, ast.While, ast.With)): stack.extend(node.body) - if hasattr(node, 'orelse'): + if hasattr(node, "orelse"): stack.extend(node.orelse) elif isinstance(node, ast.Try): stack.extend(node.body) @@ -583,7 +583,7 @@ def collect_existing_class_names(tree: ast.Module) -> set[str]: stack.extend(node.finalbody) for handler in node.handlers: stack.extend(handler.body) - + return class_names From ea14b2f5484a772f17b088970af5a92661dd9291 Mon Sep 17 00:00:00 2001 From: Kevin Turcios <106575910+KRRT7@users.noreply.github.com> Date: Mon, 16 Feb 2026 15:59:22 -0500 Subject: [PATCH 11/14] Update codeflash/languages/python/context/code_context_extractor.py Co-authored-by: claude[bot] <209825114+claude[bot]@users.noreply.github.com> --- codeflash/languages/python/context/code_context_extractor.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/codeflash/languages/python/context/code_context_extractor.py b/codeflash/languages/python/context/code_context_extractor.py index a07ba918d..3c5f80424 100644 --- a/codeflash/languages/python/context/code_context_extractor.py +++ b/codeflash/languages/python/context/code_context_extractor.py @@ -571,7 +571,7 @@ def collect_existing_class_names(tree: ast.Module) -> set[str]: if isinstance(node, ast.ClassDef): class_names.add(node.name) stack.extend(node.body) - elif isinstance(node, ast.FunctionDef): + elif isinstance(node, (ast.FunctionDef, ast.AsyncFunctionDef)): stack.extend(node.body) elif isinstance(node, (ast.If, ast.For, ast.While, ast.With)): stack.extend(node.body) From bfa55cb12856c6800e5c965b8299295c7d8b6c4e Mon Sep 17 00:00:00 2001 From: "claude[bot]" <41898282+claude[bot]@users.noreply.github.com> Date: Mon, 16 Feb 2026 21:02:03 +0000 Subject: [PATCH 12/14] fix: handle ast.Match (Python 3.10+) in collect_imports traversal The optimized collect_imports missed match/case statements where imports can legally appear.
