Compatibility with ansible 2.8 (missing ansible facts) #556
Description
We run automated weekly tests of all our roles against preview and nightly builds of ansible.
Any yum interaction with a combination of mitogen 0.2.5 and the ansible 2.8 nightly results in:
TASK [ansible_role_yum : configure packages] **********************************************************************************************************************************************************************
failed: [initial] (item={u'name': u'yum-utils'}) => {"changed": false, "item": {"name": "yum-utils"}, "msg": ["Could not detect which major revision of yum is in use, which is required to determine module backend.", "You can manually specify use_backend to tell the module whether to use the yum (yum3) or dnf (yum4) backend})"]}
failed: [initial] (item={u'name': u'yum-plugin-priorities'}) => {"changed": false, "item": {"name": "yum-plugin-priorities"}, "msg": ["Could not detect which major revision of yum is in use, which is required to determine module backend.", "You can manually specify use_backend to tell the module whether to use the yum (yum3) or dnf (yum4) backend})"]}
This happens within a docker container and also with a remote host as the target.
I have traced this back to facts not being populated correctly. These are present with ANSIBLE_STRATEGY set to linear but missing when ANSIBLE_STRATEGY is set to mitogen_linear.
"ansible_distribution": "CentOS",
"ansible_distribution_file_parsed": true,
"ansible_distribution_file_path": "/etc/redhat-release",
"ansible_distribution_file_variety": "RedHat",
"ansible_distribution_major_version": "7",
"ansible_distribution_release": "Core",
"ansible_distribution_version": "7",
This results in, when following the code, eventually the error laid out above since the selection of yum backend is dependent on the distribution being detected correctly.

This can be trivially replicated by using a centos container that has ansible 2.8 with mitogen installed:
docker run --rm -it centos bash
yum -y install epel-release
yum-config-manager --add-url=https://releases.ansible.com/ansible/rpm/nightly/devel/epel-7-x86_64/
yum install ansible
# <add mitogen to the system>
ansible -c local -i localhost, -m setup all # this is missing the facts
ANSIBLE_STRATEGY=linear ansible -c local -i localhost, -m setup # this has the distribution facts

Thanks for reporting this -- it is likely there is more breakage, I haven't tried against latest devel yet.
They have also landed become plugins, and that requires a good chunk of dev work to catch up with
