Problem with negation of "False"-evaluated vars

Hi All,

Found something strange (possible bug?) in evaluating True/False inside vars.
Only in one particular case - if variable is evaluated as “False” - its not converted to “True” with “not”

In my example false_eval is evaluated to “False” inside debug module but “not false_eval” is still “False”. Any reason for that?

- debug: var=false_eval

TASK: [debug var=false_eval] **************************************************
ok: [localhost] => {
“false_eval”: “False”
}
- debug: var={{not false_eval}}

TASK: [debug var=False] *******************************************************
ok: [localhost] => {
“False”: “False”
}

playbook.yml

  • hosts: localhost
    gather_facts: no

vars:
foo: bar
true_eval: ‘{{ foo == “bar” }}’
false_eval: ‘{{ foo != “bar” }}’

tasks:

  • debug: var=true_eval
  • debug: var={{ not true_eval }}
  • debug: var=false_eval
  • debug: var={{not false_eval}}

Output:

PLAY [localhost] **************************************************************

TASK: [debug var=true_eval] ***************************************************
ok: [localhost] => {
“true_eval”: “True”
}

TASK: [debug var=False] *******************************************************
ok: [localhost] => {
“False”: “False”
}

TASK: [debug var=false_eval] **************************************************
ok: [localhost] => {
“false_eval”: “False”
}

TASK: [debug var=False] *******************************************************
ok: [localhost] => {
“False”: “False”
}

PLAY RECAP ********************************************************************
localhost : ok=4 changed=0 unreachable=0 failed=0
