As recently there was back-and-forth with this hardcoded value
(0.001 -> 0.01 -> 0.005), obviousely the optimal value for it depends on
Ansible usage scanario and is better to be configurable.
This patch adds a new config option in DEFAULT section,
`internal_poll_interval`, with default of 0.001 corresponding to the
value hardcoded in Ansible v2.1.
This config option is then used instead of hardcoded values where
needed.

which got lost in recent big 'performance improvements' merge by @jimi-c.
I had made a previous PR to fix this, then @bcoca had committed an
improved fix. Now it's lost again.

Please note that jimi-c broke this last time as well ... seeing a
pattern here.
We couldn't copy to_unicode, to_bytes, to_str into module_utils because
of licensing. So once created it we had two sets of functions that did
the same things but had different implementations. To remedy that, this
change removes the ansible.utils.unicode versions of those functions.
* dynamic role_include
* more fixes for dynamic include roles
* set play yfrom iterator when dynamic
* changes from jimi-c
* avoid modules that break ad hoc
TODO: should really be a config
for `VariableManager._get_magic_variables()`.
This saves a lot of time re-iterating the nearly always constant global
list of groups and their members.
Generate once and cache, and invalidate cache in case `add_host:` or
`group_by:` are used.
This feature also cleans up and extends the meta subsystem:
* Allows for some meta actions (noop, clear_facts, clear_host_errors,
and end_play) to operate on a per-host basis, meaning they can work
with the free strategy as expected.
* Allows for conditionals on meta tasks.
* Fixes a bug where (for the linear strategy) metas were not treated
as a run_once task, meaning every host in inventory would run the
meta task.

Copying the TaskInclude task (which is the parent) before loading the blocks
makes the code much more simple and clean, and fixes a bug introduced during
the performance improvement changes (and specifically the change which moved
things to a single-parent model).
Fixes#17064
Since we introduced static includes in 2.1, this broke the functionality
where a notify could be sent to a named include statement, triggering all
handlers contained within the include. This patch fixes that by adding a
search through the parents of a handler for any TaskIncludes which match.
Fixes#15915
Instead of immediately returning a failed code (indicating a break in
the play execution), we internally 'or' that failure code with the result
(now an integer flag instead of a boolean) so that we can properly handle
the rescue/always portions of blocks and still remember that the break
condition was hit.
Fixes#16937
* when including statically, make sure that all parents were also included
statically (issue #16990)
* properly resolve nested static include paths
* print a message when a file is statically included
Fixes#16990
* Instead of rebuilding the handler list all over the place, we now
compile the handlers at the point the play is post-validated so that
the view of the play in the PlayIterator contains the definitive list
* Assign the dep_chain to the handlers as they're compiling, just as we
do for regular tasks
* Clean up the logic used to find a given handler, which is greatly
simplified by the above changes
Fixes#15418
Due to the fact that roles may be instantiated with different sets of
params (multiple inclusions of the same role or via role dependencies),
simply tracking notified handlers by name does not work. This patch
changes the way we track handler notifications by using the handler
object itself instead of just the name, allowing for multiple internal
instances. Normally this would be bad, but we also modify the way we
search for handlers by first looking at the notifying tasks dependency
chain (ensuring that roles find their own handlers first) and then at
the main list of handlers, using the first match it finds.
This patch also modifies the way we setup the internal list of handlers,
which should allow us to correctly identify if a notified handler exists
more easily.
Fixes#15084
This allows the PlaybookExecutor to receive more information regarding
what happened internal to the TaskQueueManager and strategy, to determine
things like whether or not the play iteration should stop.
Fixes#15523
When using run_once, there is only one dict of facts so passing that
to the VariableManager results in the fact cache containing the same
dictionary reference for all hosts in inventory. This patch fixes that
by making sure we pass a copy of the facts dict to VariableManager.
Fixes#14279
This was reinitialized every time we forked before so we weren't sharing
the same Locks. It also was not accounting for modules which were
directly invoked by an action plugin instead of going through the
strategy plguins.
If add_host is performed with hostname existing in inventory, but
not yet accessed and put in inventory cache, additional host with
same hostname and different uuid is created, causing patterns to
misbehave.
This makes our recursive, ast.parse performance measures as fast as
pre-ziploader baseline.
Since this unittest isn't testing that the returned module data is
correct we don't need to worry about os.rename not having any module
data. Should devise a separate test for the module and caching code
`ansible_failed_task`:
Contains the task data, essentially a serialized view of the Task() object.
`ansible_failed_result`:
Contains the result of the task failure, which is identical in function
to registering the result. Doing so automatically like this saves the user
from having to register every result in a block and then trying to figure
out which result had the failure
Similar to the way try/except/finally work, these variables will not be
available in the `always` portion of a block unless there is a corresponding
`rescue` first.
Fixes#12341
