[bind10-dev] Shutting down a process

[Tomek Mrugalski]

Hi,
I'm working on msgq integration with dhcp4. According to
http://bind10.isc.org/docs/bind10-guide.html#bind10.config, one can
remove a process by issuing "config remove Boss/components dhcp4". It
does not work for me (my dhcp4 process does not receive shutdown
command). When I send shutdown command explicitly ("Dhcp4 shutdown"), it
works.

Did I do something wrong? I don't have any experience with msgq, so this
my be a trivial mistake or omission.

The full set of commands is:
> config add Boss/components b10-dhcp4
> config set Boss/components/b10-dhcp4/kind dispensable
> config commit

This works:
> Dhcp4 shutdown
[command received by dhcp4 process]

This does not:
> config remove Boss/components b10-dhcp4
> config commit

My spec is
{
  "module_spec": {
    "module_name": "Dhcp4",
    "module_description": "DHCPv4 server daemon",
    "config_data": [
      { "item_name": "interface",
        "item_type": "string",
        "item_optional": false,
        "item_default": "eth0"
      }
    ],
    "commands": [
        {
            "command_name": "shutdown",
            "command_description": "Shuts down DHCPv4 server.",
            "command_args": [
                {
                    "item_name": "pid",
                    "item_type": "integer",
                    "item_optional": true
                }
            ]
        }
    ]
  }
}

Why am I not receiving shutdown command? How can I debug msgq? If remove
command is not expected to send shutdown, it should be clarified in the
documentation.

Cheers,
Tomek
