Why force set_inheritable()?

[Vbrawl]

Hi, I am making a python program that's supposed to have an auto-update feature, after updating I need to call execv to start the new process, in the new process I am trying to again create a new socket at the same address/port and because the set_inheritable is forced I get an EADDRINUSE error.

The reason is probably zero downtime?

In my case I believe it gets too complex to get the inherited sockets and put them where they need to go so I was wondering if there is a way to simply stop the inherited sockets altogether?

Is there a reason they are forced? Why not put them behind some config option the end user can toggle?

I am specifically referring to the src/hypercorn/config.py file in the end of Config._create_sockets() function

For anyone having a similar problem to my own, you can disable the set_inheritable by patching the os.set_inheritable function like below.

NOTE: This solution can have side-effects if any library you use actually depends on it.

import os
orig_inheritable = os.set_inheritable
def patched_set_inheritable(*args, **kwargs):
	return None
os.set_inheritable = patched_set_inheritable

I will leave this issue open so we can get some info on why it's like that and maybe have that config option added on a later version.
