The arguments ansible_ssh_host_key_checking and ansible_host_key_checking were missing in the documentation, while being introduced with the commit "5749845324"
In vanilla Ansible >= 12 (ansible-core 2.19)
- ssh connection plugin `verbosity` controls `ssh [-v[v[v]]]`
- config option `DEFAULT_VERBOSITY` controls whether that output is displayed
In vanilla Ansible <= 11 (ansible-core <= 2.18)
- `DEFAULT_VERBOSITY` controls both `ssh` verbosity & display verbositty
As of this change
- Mitogen + Ansible >= 12 behaviour matches vanilla Ansible >= 12.
- Mitogen + Ansible <= 11 behaviour remains unchanged
- `DEFAULT_VERBOSITY` only controls display verbosity.
- Mitogen + Ansible respect the Ansible variable `mitogen_ssh_debug_level`
I've chosen not to retroactively replicate the old vanilla Ansible behaviour
in Mitogen + Ansible <= 11 cases. I'm pretty sure it was an oversight,
rather than a design choice, but Ansible+Mitogen with `ANSIBLE_VERBOSITY=3`
is already very verbose.

Ansible 12 (ansible-core 2.19) has gained support for specifying an SSH
password, without requiring `sshpass`. It specifies the environment variable
`SSH_ASKPASS` such that `ansible` itself is called.
Mitogen is already able to support this. This change provides test coverage of
the new feature by not installing `sshpass` on macOS runners. when Ansible 12
is under test. Ubuntu runners come with `sshpass` pre-installed.
Required Ansible is also bumped to the latest pre-releases, for relevant
fixes.
Note that tests/ansible/integration/ssh/templated_by_play_taskvar.yml was
previously erroniously being skipped with ansible-core 2.19.0a<N> and
2.19.0b<N>.
fixes#1293
refs #1175
Ansible >= 12 (ansible-core >= 2.19) deprecates `stdout_callback=yaml`,
superceded by `callback_result_format=yaml`. There is a change in behaviour:
`callback_result_format` applies to output of both `ansible-playbook` _and_
`ansible`.
Tests that run `ansible` in a subprocess are now explicitly configured to use
json (even if they don't inspect that output yet) for more assert-able output
across all versions of Ansible.
The function is Ansible >= 12 (ansible-core >= 2.19). See #1274 for analysis
of `json.dumps()` vs `jsonify()` differences. This change is a middle ground
between full backward compatibility and using `json.dumps()` unadorned.
- if `data` is `None`, then it will still be transferred as `{}` on older
versions of Ansible, but 'null' in newer releases. Cases where 'null'
caused a problem are suspected/reported, but no reproducers are available.
- `ensure_ascii=True` will be still be tried, with fallback. I believe this
is only relevant on Python 2.x.
- `sort_keys=True` will no longer be used.
- No indentation/pretty printing will be applied, this remains unchanged

Python 2.7 (distro package) and 3.6 (pyenv managed) jobs run on Ubuntu 22.04.
More recent Pythons (distro or Github provided) run on 24.04.
fixes#1256
Ansible tasks that run locally (e.g. `connection: local`, `delegate_to:
localhost`) must now specify their `ansible_python_interpreter`, typically as
`{{ ansible_playbook_python }}`; otherwise the system Python on the controller
(e.g. `/usr/bin/python`) is likely to be used and this is often outside the
version range supported by the Ansible verison under test. If this occurs then
the symptom is often a failure to import a builtin from
`ansible.module_utils.six.moves`, e.g.
```

Each grouping gets an independant dir, e.g.
- ansible -> /tmp/mitogen_ci_ansible
- debops -> /tmp/mitogen_ci_debops
Importing ci_lib no longer creates a temporary directory as a side effect.
