Bug: Child Logger doesn't respect loglevel

[leandrodamascena]

Expected Behaviour

When creating Child Loggers, it should be possible to change log level.

Default Python Library

import logging

parent_logger = logging.getLogger('parent')
parent_logger.setLevel(logging.DEBUG)

parent_handler = logging.StreamHandler()
parent_formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
parent_handler.setFormatter(parent_formatter)
parent_logger.addHandler(parent_handler)
parent_logger.setLevel("INFO")

child_logger = logging.getLogger('parent.child')

child_handler = logging.StreamHandler()
child_formatter = logging.Formatter('%(name)s [%(filename)s:%(lineno)d] - %(levelname)s - %(message)s')
child_handler.setFormatter(child_formatter)
child_logger.addHandler(child_handler)
child_logger.setLevel("DEBUG")

parent_logger.debug("This is a parent logger message") # LogLevel of "parent" is INFO, won't be printed
child_logger.debug("This is a child logger message") # LogLevel of "parent.child" is DEBUG, will be printed

Powertools

from aws_lambda_powertools import Logger

logger = Logger(
    service="payment",
    location="Test1",
    level="INFO"
)

logger2 = Logger(
    service="payment",
    child=True,
    location="Test2",
    level="DEBUG" # This doesn't take effect
)

Current Behaviour

It does not respect the log level and does not emit logs if the child logger has a different log level.

Code snippet

from aws_lambda_powertools import Logger
import logging

location_format = "[%(funcName)s] %(module)s"

logger = Logger(
    service="payment",
    location=location_format,
    level="INFO"
)

logger.info("Test1")

logger2 = Logger(
    service="payment",
    child=True,
    location="Test2",
    level="DEBUG"
)
