如何防止python pylint抱怨socket类sendall方法 [英] How to prevent python pylint complaining about socket class sendall method

问题描述

我有一些代码使用简单的 tcp 套接字设置来测试某些内容.我们在我们的 python 文件上运行 pylint --errors-only，通常作为验证我们所有代码的一种方式.

然而，python 套接字库文档中给出的简单示例代码 - http://docs.python.org/library/socket.html - 将输出:

************* 模块 SocketExampleE: 16: '_socketobject' 的实例没有 'recv' 成员E: 18: '_socketobject' 的实例没有 'sendall' 成员

文档显示了这些成员、代码运行和工作.

套接字目录也显示它们存在:

<预><代码>>>>进口插座>>>s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)>>>目录['__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__',__setattr__', '__sizeof__', '__slots__', '__str__', '__subclasshook__', '__weakref__', '_sock', 'accept', 'bind', 'close', 'connect', 'connect_ex', 'dup', 'family', 'fileno', 'getpeername', 'getsockname', 'getsockopt', 'gettimeout', 'listen', 'makefile', 'proto', 'recv', 'recv_into', 'recvfrom', 'recvfrom_into', 'send', 'sendall', 'sendto', 'setblocking', 'setsockopt', 'settimeout', 'shutdown', 'type']

这归结为片段:

 用于 _delegate_methods 中的方法:setattr(自我，方法，getattr(_sock，方法))

在 socket.py 实现中.

是否可以让 pylint 接受这种样式(并验证它)，或者是使用 # pylint: disable-msg=E1101 忽略无成员"警告的唯一选择?

解决方案

您可以使用 pylint --errors-only --ignored-classes=_socketobject 或添加

[类型检查]被忽略的类=SQLObject,_socketobject

到你的 ~/.pylintrc 文件.

来自文档,

<块引用>

忽略的类:

成员属性的类名列表不应检查(对于具有动态属性的类很有用设置).

默认:SQLObject

I have a bit of code using a simple tcp socket setup to test something. We run pylint --errors-only on our python files, generally as a way to validate all our code.

However, the simple example code given on the python socket library documentation - http://docs.python.org/library/socket.html - will output:

************* Module SocketExample
E: 16: Instance of '_socketobject' has no 'recv' member
E: 18: Instance of '_socketobject' has no 'sendall' member

The documentation shows these members, the code runs and works.

A dir of socket shows them existing too:

>>> import socket
>>> s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> dir(s)
['__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__slots__', '__str__', '__subclasshook__', '__weakref__', '_sock', 'accept', 'bind', 'close', 'connect', 'connect_ex', 'dup', 'family', 'fileno', 'getpeername', 'getsockname', 'getsockopt', 'gettimeout', 'listen', 'makefile', 'proto', 'recv', 'recv_into', 'recvfrom', 'recvfrom_into', 'send', 'sendall', 'sendto', 'setblocking', 'setsockopt', 'settimeout', 'shutdown', 'type']

This is down to the snippet:

   for method in _delegate_methods:
        setattr(self, method, getattr(_sock, method))

In the socket.py implementation.

Can pylint be made to accept this style (and validate it) or is the only choice to ignore the "no member" warnings with # pylint: disable-msg=E1101?

解决方案

You can use pylint --errors-only --ignored-classes=_socketobject or add

[TYPECHECK]
ignored-classes=SQLObject,_socketobject

to your ~/.pylintrc file.

From the documenation,

ignored-classes:

List of classes names for which member attributes should not be checked (useful for classes with attributes dynamically set).

Default: SQLObject
