gRPC python socket_mutator

[Rodrigo Alexandre]

Hello everyone,

I am trying to make a gRPC client to use a specific exit interface.

For that, I am setting the value for the "socket_mutator" in the channel_arguments.

I defined a function that takes a socket as an argument and modifies it however I receive a:

TypeError: Expected int, bytes, or behavior, got <class 'function'>

Does someone know what should I place in the socket_mutator value instead?

Thank you for your time.

You're going very far off road here, but you'd need to write a C extension that instantiates a instance of grpc_socket_mutator that implements the functionality that you want, then put the pointer into a Python int object and pass it as the value in the channel arg.

I have tried that but I was not able to figure out how to make it work. Do you have any code examples of something like that being done?

As I said, you're going very far off-road here. I don't think anyone has ever tried this before.
