importlib.machinery.ModuleSpec and find_spec() were introduced in Python 3.4
under PEP 451. They replace the find_module() API of PEP 302, which was
deprecated from Python 3.4. They were removed in Python 3.12 along with the
imp module.
This change adds support for the PEP 451 APIs. Mitogen should no longer import
imp on Python versions that support ModuleSpec. Tests have been added to cover
the new APIs.
CI jobs have been added to cover Python 3.x on macOS.

Using https:// requires certificate store management and additional parameter
passing that changed across Ansible and Python versions. Using http:// allows
the same tests to be used across wider spans of Python version on the
controller, and Python verison on the targets.
Python 3.12 on a target + get_uri needs Ansible >= 8 (ansible-core >= 2.15).
Python 3.12 removed deprecated httplib.HTTPSConnection() arguments.

To do so the test suite allows a weak cryptographic alogorithm (SHA1) to be
used, principally for CentOS 6 targets. This can be removed if/when support
for older (legacy) targets is dropped.
Only the test suite enables this known weak alogorithm. Mitogen as-shipped
doesn't enable or disable algorithms.
Until Ansible 2.9 it looks like ansible_become_password had higher priority.
From Ansible 2.10 ansible_become_pass has higher priority [1]. Mitogen was not
respecting this.
I may need to rework this further, instatiating the become plugin may have
slowed down execution.
[1] Based on testing with
```
[ubuntus]
become-pass-pass ansible_become_pass=1234
become-pass-password ansible_become_password=1234
become-pass-both ansible_become_password=wrong ansible_become_pass=1234
[ubuntus:vars]
ansible_host=ubuntu2004.local
ansible_user=ubuntu
```
```

This reapplies an earlier change, when this plugin was first introduced to
Mitogen. The plugin was updated to fix
[DEPRECATION WARNING]: The '_remote_checksum()' method is deprecated.
I've elected to short-circuit the if statemtn logic, rather than
deleting/unindenting, to make the code delta much smaller. This should make it
easier to maintain/update.
Fixes#915
From cpuset(7):
> For masks longer than one word, a comma separator is used between
> words. Words are displayed in big-endian order, which has the most
> significant bit first. The hex digits within a word are also in
> big-endian order.
A few changes are bundled in this
- Ansible 2.10.x and Mitogen 0.3.x are used to build nearly all images
(Ansile 2.3.x is retained for CentOS 5, because it uses Python 2.4).
- Tox is used to install/run Ansible, replacing build_docker_images.py
- A static inventory, identifying containers by name rather than ID.
- debian-test image is renamed to debian9-test
- debian9-test image is now based on debian:9
- centos6-test image is now based on moreati/centos6-vault
following the same scheme as centos5-test.
- Images are now uploaded to Amazon Elastic Container Registry (ECR).
See #809.
- Debian recommended packages aren't installed (e.g. build-essential)
- Python 2.x and Python 3.x are installed wherever available.
- Python Virtualenv is installed wherever available.
The Travis Linux distribution must be upgraded because the Trusty
(Ubuntu 14.04) image does not have Python 3.9. Xenial (Ubuntu 16.04) is
the earliest version that offers Python 3.9.
I have not chosen a later release, in order to aid restoration of Python
2.4 - 2.6 tests.
The ansible_mitogen test suite takes over an hour when Ansible is not
accelerated by Mitogen. This change aims to reduce that by skipping
tests with a large number of iterations when the linear strategy is
chosen.
The tagged tests are intended to uncover Mitogen resource leaks. Since
Mitogen is not invoked when strategy=linear, the slight reduction in
test coverage is an acceptable trade off.
These are not part of the official testing regime (tests run for pull
requests). I find them convenient for local development.
Limitations
- Python 2.7+ only. No Python 2.4, 2.5, or 2.6.
- Requires Pythons pre-installed (e.g. DeadSnakes, pyenv)
- No coverage of alternate controller OS (e.g. MacOS)
The environments tested by default are
py27-mode_ansible-ansible2.10
py36-mode_ansible-ansible2.10
py39-mode_ansible-ansible2.10
py27-mode_mitogen
py36-mode_mitogen
py39-mode_mitogen
py27-mode_mitogen-distro_centos7

CALLBACK_VERSION et al are documented as required in
https://docs.ansible.com/ansible/2.10/dev_guide/developing_plugins.html#callback-plugins.
The need for document_fragment is noted in

This addresses the following error, seen while running
