TCP_MAXSEG cannot be set using SOL_TCP

[drewkilz]

I was testing utilizing this package on a Windows 7 Enterprise N, 64-bit machine and ran into the error listed below. The problem seems to be with attempting to set the TCP_MAXSEG socket option utilizing SOL_TCP. However, if you simply change this to using socket.SOL_SOCKET it can be set without a problem. This if my first foray into sockets, so I am not sure that is the "correct" solution.

Ran into this issue while using nameko which has dependencies for kombu which in-turn has dependencies for amqp.

Errors seen: [WinError 10042] An unknown, invalid, or unsupported option or level was specified in a getsockopt or setsockopt call For: File "C:\Program Files\Anaconda3\envs\test\lib\site-packages\amqp\transport.py", line 204, in _set_socket_options self.sock.setsockopt(SOL_TCP, opt, val)

Temporarily resolved by downgrading the version of amqp to 2.1.3 Steps:

1. Uninstall amqp using pip uninstall amqp
2. Install amqp using pip install -Iv amqp==2.1.3 . 2.1.3 version

Environment Used: OS Name: Microsoft Windows 10 Enterprise OS Version: 10.0.10586 N/A Build 10586 OS Manufacturer: Microsoft Corporation OS Build Type: Multiprocessor Free System Type: x64-based PC BIOS Version: LENOVO N11ET39W (1.15 ), 26/7/2016

Can any of you confirm this is still a problem with master?

@thedrow Can confirm this still happens and downgrading to 2.1.3 solved the issue for me.

Unfortunately, I am not able to replicate it:

>python.exe
Python 3.8.0 (tags/v3.8.0:fa919fd, Oct 14 2019, 19:37:50) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import amqp
>>> c = amqp.Connection('localhost')
>>> c.connect()
>>>

Are there any steps how to reproduce this issue?
