fix: Select ini_file module by managed node python version - #240
Conversation
Enhancement: Remove the version caps and lower bounds on the ansible.posix and community.general collection-requirements entries, leaving bare collection names so the latest versions are used. Reason: The caps (ansible.posix <2.2.0, community.general <12.0.0) existed to preserve EL7 compatibility, but tlog does not support EL7 as a managed node (meta/main.yml lists only EL 8 and 9). There is therefore no reason to hold these collections back from their latest releases. Result: tlog uses the latest ansible.posix and community.general.

On ansible 2.9 (ansible-engine) the community.general collection cannot be installed, and relying on the bundled builtin ini_file is fragile. Vendor a dependency-free copy as ini_file_ansible_29 (with the ansible.builtin.files doc fragment restored for validate-modules) and use it when ansible_version < 2.10. Newer systems use the bare ini_file name, which redirects to the latest community.general.ini_file. This also fixes the EL8 (Python 3.6) failure: community.general 12.0.0 requires Python 3.7+, so the bare-name path lets galaxy resolve a Python-3.6-safe community.general < 12.0.0 on ansible-core <= 2.16, while the vendored module covers the ansible 2.9 case where the collection is absent.

Ansible 2.9 AnsibleModule fail_json ansible attribute module_utils.basic source
💡 Result:
In Ansible 2.9, the fail_json method is a member of the AnsibleModule class defined in the ansible.module_utils.basic module [1]. It is the standard way for custom Python modules to report a failure, return an error message, and terminate execution [2]. When invoked, fail_json performs the following actions: 1. It accepts an error message (msg) and optional keyword arguments [3]. 2. It sets the 'failed' key in the return dictionary to True [3]. 3. It includes the provided error message in the 'msg' key [3]. 4. If available, it may automatically include traceback information (exception) in the output [3]. 5. It performs necessary cleanup, such as removing temporary files, by calling self.do_cleanup_files [3]. 6. It serializes the result into JSON and prints it to standard output via the _return_formatted method [3]. 7. It terminates the module process with a non-zero exit code using sys.exit(1) [3]. The source code for this functionality is located in the lib/ansible/module_utils/basic.py file within the Ansible source tree [3][4]. Developers are instructed to import it using from ansible.module_utils.basic import AnsibleModule and are advised to use fail_json instead of raising unhandled exceptions or using sys.exit directly, to ensure that Ansible can properly capture and display the module's failure state [1][2].

💡 Result:
The AnsibleModule class is a core utility provided by Ansible to simplify the development of custom modules in Python [1]. It handles essential tasks such as parsing arguments, managing check mode, and formatting JSON output for Ansible [1]. In standard practice, developers initialize AnsibleModule directly within their script rather than assigning it to a property like self.ansible. A typical implementation pattern looks like this: from ansible.module_utils.basic import AnsibleModule def run_module: module_args = dict( name=dict(type='str', required=True), state=dict(type='str', default='present', choices=['present', 'absent'])) module = AnsibleModule( argument_spec=module_args, supports_check_mode=True) # Logic to interact with the system goes here # Example: result = do_work(module.params['name']) module.exit_json(changed=True, meta='result') if name == 'main': run_module The identifier self.ansible is not a standard part of the AnsibleModule class or the conventional pattern for writing Ansible modules [1]. If you encounter code using self.ansible = AnsibleModule(...), it is likely a custom wrapper class or a specific architectural choice within a larger project, where the developer has encapsulated the module logic inside a class instance [1]. In such a case, the developer is likely using self.ansible to access the standard AnsibleModule methods (such as exit_json, fail_json, or params) throughout the lifetime of their custom object [1].

Permit documented section-only creation.
The module documentation permits omitting option when adding a section. With default allow_no_value: false, this validation rejects section: example, state: present because no value is set. Require a value only when option is provided.

Add SSSD option and idempotency assertions to the existing scenario.
The testing matrix includes Ansible 2.9 and newer versions, so tests/tests_sssd.yml can exercise both module branches. However, tests/run_sssd_tests.yml checks only sssd-session-recording.conf; it does not check the generated SSSD options or idempotency. Add assertions for both configuration sections and a second role run.

The latest community.general.ini_file uses "from __future__ import annotations", which requires python >= 3.7 and fails to import on managed nodes running python 3.6 (e.g. CentOS 8).

The ini_file task selection reads ansible_facts.python_version, but the role gathers only a restricted fact subset (!all,!min plus required facts), so python_version was missing and the conditional failed. Add the 'python' collector to __tlog_required_facts so the fact is gathered. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

ansible_facts.python_version is not part of the 'python' gather_subset,
so it stayed undefined and the ini_file conditional still failed. Read
the version from the ansible_facts.python dict instead, via a new
__tlog_python_version ("major.minor") helper var.

No tlog test playbook invokes the ini_file module directly; the module is only used inside the role via tasks/main.yml, which finds it in the role's own library/.

Select the
ini_filemodule by the managed node's python version instead of the ansible version. Gate the sssdini_filetasks onansible_facts.python_version: use the dependency-free vendoredini_file_python_36module when python < 3.7, and the bareini_filename (redirecting to the latestcommunity.general.ini_file) when python >= 3.7. Gather thepython_versionfact subset and drop the version caps on theansible.posixandcommunity.generalcollection-requirements entries.Reason
community.general12.xini_fileusesfrom __future__ import annotations, which requires python >= 3.7 and fails to import on managed nodes running python 3.6, regardless of the controller's ansible version. The vendored module imports only coreansible.module_utils, so it carries no collection dependency and also covers ansible 2.9 hosts (e.g. EL7) where the collection cannot be installed. A fully-qualified name is avoided because an unresolvable FQCN aborts play parsing on ansible 2.9 even for a task skipped bywhen, so the bare name is used.Result
tlog configures sssd with the vendored
ini_file_python_36module on python 3.6 (and py2.7/EL7) managed nodes, and the latestcommunity.general.ini_fileon nodes with python >= 3.7.This mirrors the approach in ad_integration (linux-system-roles/ad_integration#215).
