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
py36-mode_mitogen-distro_centos7
py39-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
cfa8075537/lib/ansible/plugins/callback/default.py (L28-L32)Fixes#758
This addresses the following error, seen while running
`ansible_tests.py`.
