simplified module names not working

[philfry]

Hi all,

while converting all my playbooks, plugins and stuff to ansible 2.10+ I found that simplified module names won't work with mitogen and 3rdparty modules. FQCN work, though. Simplified names of "common" collections like community.general also work, because there's a plugin_routing for those modules hardcoded in ansible itself.

• ansible version: 2.10.6
• mitogen version: v0.3.0rc1 and master
• python version: 3.9.2 (/usr/bin/python is a symlink to /usr/bin/python3)
• os: Fedora 33

For this bug report I created two repositories, one for the collection and one for the playbook examples.

To reproduce, follow these steps:

# fetch the latest stable ansible 2.10 version
git clone --depth 1 -b v2.10.6 https://github.com/ansible/ansible.git /var/tmp/ansible2106

# setup environment
. /var/tmp/ansible2106/hacking/env-setup

# fetch the examples
git clone --depth 1 --recursive https://github.com/philfry/ansiblemitogentest.git /var/tmp/mitogentest

# install the dummy collection
ansible-galaxy collection install -r /var/tmp/mitogentest/requirements.yml

Then run the example playbooks.

• play-example01.yml uses the linear stragegy (thus not using mitogen) and simplified module names. This works:

TASK [debug] *************************************************************************************
ok: [localhost] => {
    "msg": "using simplified module name, not using mitogen"
}

TASK [dummy : print hello world] *****************************************************************
[WARNING]: this is a warning
changed: [localhost] => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": true, "msg": "Hello world"}

• play-example02.yml uses mitogen_linear and FQCN. This works, too:

TASK [debug] *************************************************************************************
ok: [localhost] => {
    "msg": "using fqcn, using mitogen"
}

TASK [dummy_noshort : print hello world] *********************************************************
[WARNING]: this is a warning
changed: [localhost] => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python3"}, "changed": true, "msg": "Hello world"}

• play-example03.yml uses mitogen_linear and simplified module names. This breaks:

TASK [debug] *************************************************************************************
ok: [localhost] => {
    "msg": "using simplified module name, using mitogen"
}

TASK [dummy : print hello world] *****************************************************************
fatal: [localhost]: FAILED! => {"msg": "The module hello was not found in configured module paths"}

Attached: ANSIBLE_DEBUG=1 ansible-playbook play-example03.yml -vvvvv play-example03.txt

fwiw, also affects ansible 2.9.18 with mitogen 0.2.9.

Just ran into this myself with ansible 2.9.18 and mitogen 0.2.10rc1.

Any plans to try to address this soon?

Unfortunately this remains a big issue with using mitogen with ansible collections.
