This is unsafe and we debated re-adding it to the v2/2.0 codebase,
however it is a common-enough feature that we will simply mark it
as deprecated for now and remove it at some point in the future.
Fixes#11718
added deprecation warning
fixed display.deprecated to make version optional (code already assumed this)
turned warning + 'deprecated' in plugin loader into actual call to deprecated()
This allows not messing up the wonderful error reporting that is
carefully created. Instead of:
$ ansible-playbook foo.yml
[ERROR]: ERROR! 'foo' is not a valid attribute for a Task The error appears
to have been in '/Users/marca/dev/git-repos/ansible/foo.yml': line 4, column 7,
but may be elsewhere in the file depending on the exact syntax problem. The
offending line appears to be: tasks: - name: do something ^ here
we get:
$ ansible-playbook foo.yml
ERROR! 'foo' is not a valid attribute for a Task
The error appears to have been in '/Users/marca/dev/git-repos/ansible/foo.yml': line 4, column 7, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
tasks:
- name: do something
^ here
which is much nicer.
