bindctl crashes, when trying to add to non-existing list entry. While I was learning how to write bindctl, commands I've crashed it couple times.

Error handling should be improved. It is frustrating, when user types long configuration and then due to one syntax error bindctl crashes and all changes are lost.

This works:
config set Dhcp6/subnet6[0]/valid-lifetime 1000

However, this:
config add Dhcp6/subnet6[0] valid-lifetime 1000

will crash bindctl:

thomson@billabong:~/devel/bind10/src/bin/dhcp6$ bindctl 
["login success "] login as root
> config add Dhcp6/subnet6[0] valid-lifetime 1000
Traceback (most recent call last):
  File "/usr/lib/python3.2/", line 214, in onecmd
    func = getattr(self, 'do_' + cmd)
AttributeError: 'BindCmdInterpreter' object has no attribute 'do_config'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/bin/bindctl", line 151, in <module>
    result =
  File "/usr/local/lib/python3/dist-packages/bindctl/", line 140, in run

  File "/usr/local/lib/python3/dist-packages/isc/config/", line 533, in _add_value_to_list
AttributeError: 'dict' object has no attribute 'append'

I've used code from branch #2269, but I think that is a generic issue.

Please see ticket #2254.

From today's jabber:

(08:13:26 AM) jelte: oh actually, i think 2254 accidentally fixes 2290 as well

(08:14:54 AM) jelte: should fix most if not all instances where you do add or remove to something that does not support addition/removal

  • Milestone changed from New Tasks to Sprint-20121009

0 points ticket. During this sprint, Jelte will check if this has been fixed already and then we'll estimate it if necessary.
