本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

案例
HOW- 目标
- Subclass the right object proxy base in wrapt 2.x so iteration works
- 符号
-
- BaseObjectProxy
- ObjectProxy
- AutoObjectProxy
- with_signature
- function_wrapper
- 环境
- python 3.12
- 创建时间
- 2026-08-14T20:44:52Z
契约
- assert ObjectProxy is a subclass of BaseObjectProxy, not an alias for it
- assert BaseObjectProxy around a list refuses to iterate while isinstance and hasattr both claim it is iterable
- assert the 1.x shape of subclassing ObjectProxy still iterates, but reports a non-iterable as iterable
- assert AutoObjectProxy agrees with reality both ways and builds a new class per instance
- assert wrapt.signature is a module so calling it raises TypeError, while inspect.signature reads the original signature through a wrapt decorator
- assert wrapt.function_wrapper is not wrapt.decorator and takes no enabled/adapter/proxy keywords
- assert proxy subclass state needs the _self_ prefix or it leaks onto the wrapped object
