Use ArgumentSpecValidator in AnsibleModule (#73703)
* Begin using ArgumentSpecValidator in AnsibleModule

* Add check parameters to ArgumentSpecValidator

Add additional parameters for specifying required and mutually exclusive parameters.
Add code to the .validate() method that runs these additional checks.

* Make errors related to unsupported parameters match existing behavior

Update the punctuation in the message slightly to make it more readable.
Add a property to ArgumentSpecValidator to hold valid parameter names.

* Set default values after performining checks

* FIx sanity test failure

* Use correct parameters when checking sub options

* Use a dict when iterating over check functions

Referencing by key names makes things a bit more readable IMO.

* Fix bug in comparison for sub options evaluation

* Add options_context to check functions

This allows the parent parameter to be added the the error message if a validation
error occurs in a sub option.

* Fix bug in apply_defaults behavior of sub spec validation

* Accept options_conext in get_unsupported_parameters()

If options_context is supplied, a tuple of parent key names of unsupported parameter will be
created. This allows the full "path" to the unsupported parameter to be reported.

* Build path to the unsupported parameter for error messages.

* Remove unused import

* Update recursive finder test

* Skip if running in check mode

This was done in the _check_arguments() method. That was moved to a function that has no
way of calling fail_json(), so it must be done outside of validation.

This is a silght change in behavior, but I believe the correct one.

Previously, only unsupported parameters would cause a failure. All other checks would not be executed
if the modlue did not support check mode. This would hide validation failures in check mode.

* The great purge

Remove all methods related to argument spec validation from AnsibleModule

* Keep _name and kind in the caller and out of the validator

This seems a bit awkward since this means the caller could end up with {name} and {kind} in
the error message if they don't run the messages through the .format() method
with name and kind parameters.

* Double moustaches work

I wasn't sure if they get stripped or not. Looks like they do. Neat trick.

* Add changelog

* Update unsupported parameter test

The error message changed to include name and kind.

* Remove unused import

* Add better documentation for ArgumentSpecValidator class

* Fix example

* Few more docs fixes

* Mark required and mutually exclusive attributes as private

* Mark validate functions as private

* Reorganize functions in validation.py

* Remove unused imports in basic.py related to argument spec validation

* Create errors is module_utils

We have errors in lib/ansible/errors/ but those cannot be used by modules.

* Update recursive finder test

* Move errors to file rather than __init__.py

* Change ArgumentSpecValidator.validate() interface

Raise AnsibleValidationErrorMultiple on validation error which contains all AnsibleValidationError
exceptions for validation failures.

Return the validated parameters if validation is successful rather than True/False.

Update docs and tests.

* Get attribute in loop so that the attribute name can also be used as a parameter

* Shorten line

* Update calling code in AnsibleModule for new validator interface

* Update calling code in validate_argument_spec based in new validation interface

* Base custom exception class off of Exception

* Call the __init__ method of the base Exception class to populate args

* Ensure no_log values are always updated

* Make custom exceptions more hierarchical

This redefines AnsibleError from lib/ansible/errors with a different signature since that cannot
be used by modules. This may be a bad idea. Maybe lib/ansible/errors should be moved to
module_utils, or AnsibleError defined in this commit should use the same signature as the original.

* Just go back to basing off Exception

* Return ValidationResult object on successful validation

Create a ValidationResult class.
Return a ValidationResult from ArgumentSpecValidator.validate() when validation is successful.
Update class and method docs.
Update unit tests based on interface change.

* Make it easier to get error objects from AnsibleValidationResultMultiple

This makes the interface cleaner when getting individual error objects contained in a single
AnsibleValidationResultMultiple instance.

* Define custom exception for each type of validation failure

These errors indicate where a validation error occured. Currently they are empty but could
contain specific data for each exception type in the future.

* Update tests based on (yet another) interface change

* Mark several more functions as private

These are all doing rather "internal" things. The ArgumentSpecValidator class is the preferred
public interface.

* Move warnings and deprecations to result object

Rather than calling deprecate() and warn() directly, store them on the result object so the
caller can decide what to do with them.

* Use subclass for module arg spec validation

The subclass uses global warning and deprecations feature

* Fix up docs

* Remove legal_inputs munging from _handle_aliases()

This is done in AnsibleModule by the _set_internal_properties() method. It only makes sense
to do that for an AnsibleModule instance (it should update the parameters before performing
validation) and shouldn't be done by the validator.

Create a private function just for getting legal inputs since that is done in a couple of places.

It may make sense store that on the ValidationResult object.

* Increase test coverage

* Remove unnecessary conditional

ci_complete

* Mark warnings and deprecations as private in the ValidationResult

They can be made public once we come up with a way to make them more generally useful,
probably by creating cusom objects to store the data in more structure way.

* Mark valid_parameter_names as private and populate it during initialization

* Use a global for storing the list of additonal checks to perform

This list is used by the main validate method as well as the sub spec validation.

Let get_file_attributes() work without `lsattr -v` (#71845)
* Let get_file_attributes() work without `lsattr -v`

Change:
- module_utils's get_file_attributes() expects `lsattr -v` to work, but
  in some cases, it may not.
- The function now takes an optional include_version bool parameter,
  which removes this expectation.
- Places where we call get_file_attributes() without using the 'version'
  it returns, we now call it with include_version=False.

Test Plan:
- New unit tests

Change default file permissions so they are not world readable (#70221)
* Change default file permissions so they are not world readable

CVE-2020-1736

Set the default permissions for files we create with atomic_move() to 0o0660. Track
which files we create that did not exist and warn if the module supports 'mode'
and it was not specified and the module did not call set_mode_if_different(). This allows the user to take action and specify a mode rather than using the defaults.

A code audit is needed to find all instances of modules that call atomic_move()
but do not call set_mode_if_different(). The findings need to be documented in
a changelog since we are not warning. Warning in those instances would be frustrating
to the user since they have no way to change the module code.

- use a set for storing list of created files
- just check the argument spac and params rather than using another property
- improve the warning message to include the default permissions

Toshio Kuratomi 6531ba38f8 Allow the msg argument to fail_json() to be a positional argument
fial_json() requires a message be given to it to inform the end user of
why the module failed.  Prior to this commit, the message had to be a
keyword argument:

    module.fail_json(msg='Failed due to error')

Since this is a required parameter, this commit allows the message to be
given as a positional argument instead:

   module.fail_json('Failed due to an error')

kaorihinata 3ca4580cb4 Allow no_log=False to silence the no_log warnings for module parameters (#64733)
As AnsibleModule._log_invocation is currently implemented, any parameter
with a name that matches PASSWORD_MATCH triggers the no_log warning as a
precaution against parameters that may contain sensitive data, but have not
been marked as sensitive by the module author.

This patch would allow module authors to explicitly mark the aforementioned
parameters as not sensitive thereby bypassing an erroneous warning message,
while still catching parameters which have not been marked at all by the
author.

Adds tests for various no_log states including True, False, and None (as
extracted by AnsibleModule._log_invocation) when applied to an argument with
a name that matches PASSWORD_MATCH.

Dag Wieers cd9471ef17 Introduce new 'required_by' argument_spec option (#28662)
* 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)
