AttributeError: 'socket' object has no attribute 'SOL_SOCKET' (ESP8266)

closedby troublegumopened 2019-10-08updated 2019-10-08

I have error: "object has no attribute 'SOL_SOCKET'".

MicroPython v1.11-8-g48dcbbe60 on 2019-05-29; ESP module with ESP8266

My code example:
import socket
socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

What did I do wrong?

Both issues report missing socket constants causing AttributeError — query is about SO_BROADCAST, candidate is about SOL_SOCKET (and SO_REUSEADDR) on ESP8266. Same root cause category (MicroPython's socket module omits various POSIX socket constants), same code area (extmod/modsocket), same error pattern. However, they are distinct constants and fixing one does not resolve the other. Neither issue references the other, and they may have different implementation paths depending on port.

Suggested action

Link the issues as related — both concern missing socket option constants in extmod/modsocket. Any fix that adds broader socket constant coverage (e.g. a batch addition of SOL_SOCKET, SO_BROADCAST, SO_REUSEADDR etc.) should reference both. Neither should be closed in favour of the other.
