🔍 代码审查总结

本 PR 实现了节点循环执行机制。审查发现以下关键问题需要处理:

🚨 严重问题

  1. 索引越界风险:loop.py:39 在分割字符串时未做边界检查,可能导致 IndexError
  2. 除零风险:validator.py:51 在空列表上调用 min() 会抛出 ValueError

⚠️ 逻辑问题

  1. 异常处理宽泛:decorators.py:48 捕获所有异常但仅记录日志,可能掩盖严重错误
  2. 状态判断逻辑:operations.py:496 的状态判断仅检查 _result 字段,可能不够健壮

✨ 建议

  • 建议添加单元测试覆盖边界情况(空列表、索引越界等)
  • 考虑为新增的 loop_config 字段添加 schema 验证

审查了 8 个变更文件,标注了 4 个高优先级问题

def get_value(self):
# 循环节点因引用
if hasattr(self, "inner_loop") and self.inner_loop != -1:
return self.value.split(",")[self.inner_loop - 1]

🚨 索引越界风险:当 inner_loop 超过数组长度时会抛出 IndexError。建议添加边界检查:

values = self.value.split(",")
if self.inner_loop > len(values):
    raise ValueError(f"inner_loop {self.inner_loop} exceeds values length {len(values)}")
return values[self.inner_loop - 1]

)
record_kwargs = {**kwargs, "func_result": result}
recorder.record(*args, **record_kwargs)
except Exception as e:

⚠️ 异常处理过于宽泛:捕获所有异常可能掩盖严重错误。建议只捕获预期的异常类型(如 KeyError),让其他异常向上传播

continue

🚨 空列表异常:当 loop_params 为空字典时,min() 会抛出 ValueError。建议先检查是否为空:

if not loop_params:
    raise exceptions.ParserWebTreeException("loop_params is empty")
lengths = [len(param.split(",")) for key, param in loop_params.items()]
if loop_config["loop_times"] != min(lengths):
    raise exceptions.ParserWebTreeException("loop times not matched")


# 重试记录必然是因为失败才重试,设置了循环策略的节点只有成功才能接着循环
if node_info.loop_strategy:
if hist["skip"] or hist["outputs"].get("_result"):

⚠️ 状态判断可能不够健壮:仅通过 outputs.get("_result") 判断成功可能不准确,_result 可能为 False 但节点实际成功。建议明确检查:

if hist["skip"] or (hist["outputs"].get("_result") is True):
