How to detect a rescued task while using the CallbackBase?

[Victor Martinez]

Hi all,

I'd like to distinguish a failed task from a rescued time using a callback plugin, but I cannot see anything in https://github.com/ansible/ansible/blob/devel/lib/ansible/plugins/callback/__init__.py

Any hints how I can distinguish those two different status at the task level?

Thanks

I meant `rescued`

I raised a proposal in https://github.com/ansible/ansible/pull/76934 but it was not accepted, the implementation was a kind of to the one regarding the ignore_errors, for similar reasons, since lib/ansible/plugins/strategy/__init__.py seems to be the one in charge to run tasks and notify the callback.

There is a hint in the comment for closing the above-mentioned PR about a different alternative:

• The 'rescue' is not the only property of a task you might want to examine
• the 'res' property already includes the 'task' which should be able to access these same properties

I tried to debug the res property in any given task by printing the content for the result in 

def v2_runner_on_failed(self, result, ignore_errors=False):

self._display.warning(str(result._result))

But given the below playbook:

- name: MyPlabook

hosts: localhost

connection: local

tasks:

- block:

- name: Invalid URL on purpose

uri:

url: "http://url.does.not.exist"

method: "GET"

rescue:

- name: Rescue block (perform recovery)

debug:

msg: "Something went wrong, cleaning up.."

The output looks like:

TASK [Invalid URL on purpose] ********************************************************************************************************************************************************

fatal: [localhost]: FAILED! => {"changed": false, "elapsed": 0, "msg": "Status code was -1 and not [200]: Request failed: <urlopen error [Errno 8] nodename nor servname provided, or not known>", "redirected": false, "status": -1, "url": "http://url.does.not.exist"}

Unfortunately I cannot find any references in the result object that can help me to know that it was rescued. Any ideas what's the data structure I need to search for to know if any given task was rescued?

Hi all,

I was not able to find the way to detect a rescued task within the CallbackBase. Any hints if that's possible?

Thanks
