* Build documentation for Ansible-2.10 (formerly known as ACD).
Builds plugin docs from collections whose source is on galaxy
The new command downloads collections from galaxy, then finds the
plugins inside of them to get the documentation for those plugins.
* Update the python syntax checks
* docs builds can now require python 3.6+.
* Move plugin formatter code out to an external tool, antsibull-docs.
Collection owners want to be able to extract docs for their own
websites as well.
* The jinja2 filters, tests, and other support code have moved to antsibull
* Remove document_plugins as that has now been integrated into antsibull-docs
* Cleanup and bugfix to other build script code:
* The Commands class needed to have its metaclass set for abstractmethod
to work correctly
* Fix lint issues in some command plugins
* Add the docs/docsite/rst/collections to .gitignore as
everything in that directory will be generated so we don't want any of
it saved in the git repository
* gitignore the build dir and remove edit docs link on module pages
* Add docs/rst/collections as a directory to remove on make clean
* Split the collections docs from the main docs
* remove version and edit on github
* remove version banner for just collections
* clarify examples need collection keyword defined
* Remove references to plugin documentation locations that no longer exist.
* Perhaps the pages in plugins/*.rst should be deprecated
altogether and their content moved?
* If not, perhaps we want to rephrase and link into the collection
documentation?
* Or perhaps we want to link to the plugins which are present in
collections/ansible/builtin?
* Remove PYTHONPATH from the build-ansible calls
One of the design goals of the build-ansible.py script was for it to
automatically set its library path to include the checkout of ansible
and the library of code to implement itself. Because it automatically
includes the checkout of ansible, we don't need to set PYTHONPATH in
the Makefile any longer.
* Create a command to only build ansible-base plugin docs
* When building docs for devel, only build the ansible-base docs for
now. This is because antsibull needs support for building a "devel
tree" of docs. This can be changed once that is implemented
* When building docs for the sanity tests, only build the ansible-base
plugin docs for now. Those are the docs which are in this repo so
that seems appropriate for now.
A little further down the page is another index, ansible_loop.index, which shares a similar description but is 1 indexed.
Its zero indexed twin has a 0 suffix.
``ansible_loop.index`` The current iteration of the loop. (1 indexed)
``ansible_loop.index0`` The current iteration of the loop. (0 indexed)
To remove ambiguity around the usage of index_var, explicitly mention that this variable is 0 indexed.
Change:
Our handling of NetBSD virtualization facts led to facts that were just
plain incorrect. One example is reporting Xen even when the system is
running on something completely different (like KVM).
As stated by the reporter of #69352, NetBSD has a better sysctl setting
to use for this information, machdep.hypervisor.
This PR does the following:
- Try to use machdep.hypervisor sysctl value if the other sysctl values
we check don't end up with enough information to be useful
- Only look for /dev/xencons and assume Xen if nothing else works
(Really this should probably return 'unknown' since the file exists on
non-Xen systems and is not very useful).
- Add a few more patterns (Xen matches and also Hyper-V) to
VirtualSysctlDetectionMixin#detect_virt_product.
This change is slightly breaking:
- If the first two attempts at using sysctl worked before,
(machdep.dmi.system-product and machdep.dmi.system-vendor), they will
continue to work.
- For cases when those values didn't work, previously the existence of
/dev/xencons was checked, and if found, we reported 'xen' (even on
non-Xen systems when the file existed). After this PR, we try the
machdep.hypervisor sysctl key before still falling back to
/dev/xencons. This means that in some cases, we might go from
(wrongly) saying "xen" to giving a more accurate value such as "kvm"
or "Hyper-V".
Test Plan:
- Tested with local NetBSD VM and got 'kvm' instead of 'xen' back.
Tickets:
- Fixes#69352

* Add type for options in the sample module shown in Developing Modules, as this is required to have the tests being
green
* Remove duplicated strings: the same sentence is in "Python tips" and "Module security", keeping the
latter.
Previous version initialized the `TaskQueueManager` after calling
`Play.load()` while advertising a way to inject a custom library
location path. This caused the tasks loader not to find any custom
modules because it was triggered before the path was actually added
to the module loader.
This patch changes the order of the operations to ensure that the
customized `context.CLIARGS` actually influences things.
Resolves https://github.com/ansible/ansible/issues/69758.
If a local module has no documentation, the doc command will fail without any hints of what is wrong. Add another way to confirm the presence of a local module.

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.

When an ansible module, e.g., command, does not support check mode, you can use "check_mode: no" in that task to execute the task in normal mode, even when "--check" flag is used. The current document basically says, use "check_mode: no" to run in check mode, which is confusing and inaccurate.
