Pull Request Overview

This PR adds robust error handling for attribute access in rule filtering functions to handle cases where rule objects may be missing expected attributes like source, dest, or action_id.

• Wrapped attribute access in try-catch blocks for filter_rules_in_network, split_rules_for_user, and filter_rules_action functions
• Added comprehensive test cases for edge cases with missing or incomplete rule attributes
• Updated version to 1.1.4 with changelog entry

The try-catch block only catches AttributeError but not other exceptions that network_in_range might raise. Based on the context, network_in_range can raise ValueError for invalid network formats, which would not be caught here and could cause unexpected crashes.

ValueError is catched in the network_in_range validator

def network_in_range(address, mask, net_ranges):
    """
    check if given ip address is in user network ranges
    :param address: string ip_address
    :param net_ranges: list of network ranges
    :return: boolean
    """
    result = False
    network = "{}/{}".format(address, mask)
    for adr_range in net_ranges:
        try:
            result = result or subnet_of(ipaddress.ip_network(network), ipaddress.ip_network(adr_range))
        except TypeError:  # V4 can't be a subnet of V6 and vice versa
            pass
        except ValueError:
            return False

    return result
