Error while reading from socket: (11, 'Resource temporarily unavailable')

[n00b-bot]

While developing, I face this error. After searching, I found https://bytemeta.vip/repo/andymccurdy/redis-py/issues/1387?page=1 to fix it.

Sumary

On most platforms, BlockingIOError is raised with an errno.EWOULDBLOCK error number. But Jypthon(on Windows) uses a different error to indicate that the socket would block which is errno.EAGAIN error number.
NONBLOCKING_EXCEPTIONS tuple only have errno.EWOULDBLOCK on the whitelist.

But the error is errno.EAGAIN , so the if condition is false and then raise ConnectionError

Solution

Add the errno.EAGAIN to the whitelist only once.

import errno
import socket
from redis import connection
connection.NONBLOCKING_EXCEPTION_ERROR_NUMBERS[socket.error] = errno.EAGAIN
connection.NONBLOCKING_EXCEPTIONS = tuple(connection.NONBLOCKING_EXCEPTION_ERROR_NUMBERS.keys())
