本次提交修复了 Issue #34 中提到的核心稳定性问题: 1. **B1: 优化 O(N²) Scope Lookup** - 在 ContextAwareVisitor 中建立 defnode_to_scope 哈希映射 - 将作用域查找从 O(N²) 优化到 O(1) - 在 AdvancedNodeTransformer 中优先使用哈希映射查找 2. **B2: 修复运行时别名冲突(部分完成)** - 为所有 import 语句添加 __mod 后缀 - 在 deduplicate_imports 中为别名添加后缀 - 在 visit_Import 和 visit_ImportFrom 中统一处理别名 - 避免了导入符号与本地定义的冲突 3. **B3: 实现属性引用验证** - 在 ReferenceValidator.visit_Attribute 中添加属性验证逻辑 - 递归解析属性链,获取根符号 - 检查类成员和方法是否存在 - 对外部模块(os, sys 等)跳过属性检查 4. **B4: 修复类-方法拓扑顺序** - 在 topological_sort 中添加类到方法的依赖边 - 确保类总是在其方法之前输出 - 支持多继承和混入场景 同时添加了相应的测试用例: - test_perf_hash_lookup.py: 测试性能优化 - test_runtime_alias_conflict.py: 测试别名冲突修复 - test_attr_reference_validation.py: 测试属性引用验证 - test_class_method_order_multi_inherit.py: 测试类方法顺序 添加了 GitHub Actions CI 工作流以确保持续集成。 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

概述
本 PR 修复了 Issue #34 中识别的 4 个核心稳定性阻塞缺陷,显著提升了代码合并工具的性能、可靠性和准确性。
修复的问题清单
✅ B1 - O(N²) Scope Lookup 性能问题
问题:
AdvancedNodeTransformer.transform_function通过线性搜索查找作用域,在大型项目中导致性能雪崩(>30s)修复:
ContextAwareVisitor中添加defnode_to_scope哈希映射✅ B2 - Runtime Alias Name Conflict(部分修复)
问题:
import orjson as json+ 本地def json():导致运行时 TypeError修复:
generate_name_mappings中为所有 import alias 添加_mod后缀visit_Name、visit_Attribute中的别名映射逻辑try...except ImportError场景中的别名重映射已知限制:
importlib.import_module)暂不支持✅ B3 - Attribute Reference Validation 增强
问题:
ReferenceValidator不检查属性引用(如obj.attr),导致拼写错误和缺失导入无法被发现修复:
visit_Attribute方法,递归解析属性链os.path,sys.version)✅ B4 - Class → Method Topology 拓扑排序
问题:类可能在其方法之后输出,导致多继承/混入场景下的 NameError
修复:
topological_sort中为类添加到其方法的依赖边class_children索引优化实现测试覆盖
新增测试文件
tests/test_perf_hash_lookup.pypytest.mark.timeout(6)确保性能边界tests/test_runtime_alias_conflict.pyimport orjson as json+ 本地def json()场景try...except ImportError的复杂场景tests/test_attr_reference_validation.pynamedtuplezvsnamedtuple)os.path.join)tests/test_class_method_order_multi_inherit.py测试结果
pytest -v和pytest -v --merged双模式下全部通过ASTAuditor对所有测试场景报告 0 error实现细节
性能优化(B1)
别名冲突处理(B2)
属性验证(B3)
拓扑排序增强(B4)
