* Introduce new "required_by' argument_spec option
This PR introduces a new **required_by** argument_spec option which allows you to say *"if parameter A is set, parameter B and C are required as well"*.
- The difference with **required_if** is that it can only add dependencies if a parameter is set to a specific value, not when it is just defined.
- The difference with **required_together** is that it has a commutative property, so: *"Parameter A and B are required together, if one of them has been defined"*.
As an example, we need this for the complex options that the xml module provides. One of the issues we often see is that users are not using the correct combination of options, and then are surprised that the module does not perform the requested action(s).
This would be solved by adding the correct dependencies, and mutual exclusives. For us this is important to get this shipped together with the new xml module in Ansible v2.4. (This is related to bugfix https://github.com/ansible/ansible/pull/28657)
```python
module = AnsibleModule(
argument_spec=dict(
path=dict(type='path', aliases=['dest', 'file']),
xmlstring=dict(type='str'),
xpath=dict(type='str'),
namespaces=dict(type='dict', default={}),
state=dict(type='str', default='present', choices=['absent',
'present'], aliases=['ensure']),
value=dict(type='raw'),
attribute=dict(type='raw'),
add_children=dict(type='list'),
set_children=dict(type='list'),
count=dict(type='bool', default=False),
print_match=dict(type='bool', default=False),
pretty_print=dict(type='bool', default=False),
content=dict(type='str', choices=['attribute', 'text']),
input_type=dict(type='str', default='yaml', choices=['xml',
'yaml']),
backup=dict(type='bool', default=False),
),
supports_check_mode=True,
required_by=dict(
add_children=['xpath'],
attribute=['value', 'xpath'],
content=['xpath'],
set_children=['xpath'],
value=['xpath'],
),
required_if=[
['count', True, ['xpath']],
['print_match', True, ['xpath']],
],
required_one_of=[
['path', 'xmlstring'],
['add_children', 'content', 'count', 'pretty_print', 'print_match', 'set_children', 'value'],
],
mutually_exclusive=[
['add_children', 'content', 'count', 'print_match','set_children', 'value'],
['path', 'xmlstring'],
],
)
```
* Rebase and fix conflict
* Add modules that use required_by functionality
* Update required_by schema
* Fix rebase issue
* Move ansible.compat.tests to test/units/compat/.
* Fix unit test references to ansible.compat.tests.
* Move builtins compat to separate file.
* Fix classification of test/units/compat/ dir.
* Allow subspec defaults to be processed when the parent argument is not supplied
* Allow this to be configurable via apply_defaults on the parent
* Document attributes of arguments in argument_spec
* Switch manageiq_connection to use apply_defaults
* add choices to api_version in argument_spec
* basic: allow one or more when param list having choices
* add unit tests
* optimize a bit
* re-add get_exception import
* a number of existing modules expect to be able to get it from basic.py
Split the one monolithic test for basic.py into several files
* Split test_basic.py along categories.
This is preliminary to get a handle on things. Eventually we may want
to further split it so each file is only testing a single function.
* Cleanup unused imports from splitting test_basic.py
* Port atomic_move test to pytest.
Working on getting rid of need to maintain procenv
* Split a test of symbolic_mode_to_octal to follow unittest best practices
Each test should only invoke the function under test once
* Port test_argument_spec to pytest.
* Fix suboptions failure
* Porting tests to pytest
* Achievement Get: No longer need mock/generator.py
* Now done via pytest's parametrization
* Port safe_eval to pytest
* Port text tests to pytest
* Port test_set_mode_if_different to pytest
* Change conftest AnsibleModule fixtures to be more flexible
* Move the AnsibleModules fixtures to module_utils/conftest.py for sharing
* Testing the argspec code requires:
* injecting both the argspec and the arguments.
* Patching the arguments into sys.stdin at a different level
* More porting to obsolete mock/procenv.py
* Port run_command to pytest
* Port known_hosts tests to pytest
* Port safe_eval to pytest
* Port test_distribution_version.py to pytest
* Port test_log to pytest
* Port test__log_invocation to pytest
* Remove unneeded import of procenv in test_postgresql
* Port test_pip to pytest style
* As part of this, create a pytest ansiblemodule fixture in
modules/conftest.py. This is slightly different than the
approach taken in module_utils because here we need to override the
AnsibleModule that the modules will inherit from instead of one that
we're instantiating ourselves.
* Fixup usage of parametrization in test_deprecate_warn
* Check that the pip module failed in our test
* Module argument_spec now accepts a callable for the type argument, which is passed through and called with the value when appropriate. On validation/conversion failure, the name of the callable (or its type as a fallback) is used in the error message.
* adds basic smoke tests for custom callable validator functionality
