Running from Source - callbacks error

Hi…

I just setup a new ubuntu system to run from source using the “sudo make install” command. When I try to run scripts that use “from ansible import callbacks” Python gives an error that callbacks doesn’t exist. If I just try running the following from the command line I get the same:

vagrant@precise64:~/ansible$ python
Python 2.7.3 (default, Jun 22 2015, 19:33:41)
[GCC 4.6.3] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.

from ansible import callbacks
Traceback (most recent call last):
File “”, line 1, in
ImportError: cannot import name callbacks

However importing other things like ansible utils does work.

I notice that there are no longer any callback py or pyc files in /usr/local/lib/python2.7/dist-packages/ansible-2.0.0-py2.7.egg/ansible/:

Are callbacks being referenced differently now?

they should be under plugins/callbacks

3

I see plugins/callback (notice it’s singular) and the contents don’t appear to be the same as the callbacks py/pyc files from earlier.

we have not finished porting allt he callbacks, the API has changed a
bit, but the default ones used by ansible and ansible-playbook should
be there

Ok, can you please try this simple test and let me know if you see the same?

Start with new ubuntu machine

$ git clone git://github.com/ansible/ansible.git --recursive
$ cd ./ansible
$ sudo make install

$ python

from ansible import callbacks
Traceback (most recent call last):
File “”, line 1, in
ImportError: cannot import name callbacks

"from ansible import callbacks" is not valid in v2

7

Is there doc on how to do this in v2? The equivalent of:

from ansible import callbacks
from ansible import utils

stats = callbacks.AggregateStats()
playbook_cb = callbacks.PlaybookCallbacks(verbose=utils.VERBOSITY)
runner_cb = callbacks.PlaybookRunnerCallbacks(stats, verbose=utils.VERBOSITY)
8

no, we really never have had API docs, the changes in v2 are
substantial and you'll probably need to rewrite all that, for example
runner does not exist anymore.
