Also fixes a discovered bug in block rescue detection related to inserting
the ansible_failed_{result|task} variables when the rescue is in a nested
block.
* configurable list of facts modules
- allow for args dict for specific modules
- add way to pass parameters
- avoid facts poluting test
- move to 'facts gathered' flag
- add 'gathering' setting tests
* More concisely reparent, ensuring we don't go too shallow or too deep in this process. Fixes#38357
* More explicit reparenting, with a short circuit for a common case
* We need new_block to have a parent, otherwise we lose context with this approach
* Remove duplicate parent assignment
* Change callers of Block.copy to not use exclude_parent=True, when including the parent, exclude tasks
* Cache tasks as they are queued instead of en masse
This also moves the task caching from the PlayIterator to the
StrategyBase class, where it makes more sense (and makes it easier
to not have to change the strategy class methods leading to an API
change).
Fixes#31673
* Cleaning up unit tests due to 502ca780
currently it is doing only from the 'active' hosts in the batch which means
the percentage goes up as hosts fail instead of staying the same.
added debug info for max fail
fixes#32255
Consolidate the module_utils, constants, and config functions that
convert values into booleans into a single function in module_utils.
Port code to use the module_utils.validate.convert_bool.boolean function
isntead of mk_boolean.
`variable_manager` is passed to the constructor of `PlayIterator`,
and then used to access the fact cache when fact gathering.
Make `_variable_manager` an attribute of the `PlayIterator` class

* reworked vars and vars precedence
- vars plugins now load group/host_vars dirs
- precedence for host vars is now configurable
- vars_plugins been reworked
- removed unused vars cache
- removed _gathered_facts as we are not keeping info in host anymore
- cleaned up tests
- fixed ansible-pull to work with new inventory
- removed version added notation to please rst check
- inventory in config relative to config
- ensures full paths on passed inventories
* implicit localhost connection local
* Update module_utils.six to latest
We've been held back on the version of six we could use on the module
side to 1.4.x because of python-2.4 compatibility. Now that our minimum
is Python-2.6, we can update to the latest version of six in
module_utils and get rid of the second copy in lib/ansible/compat.
Rather than trying to enumerate tasks or track an ever changing cur_role
flag in PlayIterator, this change simply sets a flag on the last block in
the list of blocks returned by Role.compile(). The PlayIterator then checks
for that flag when the cur_block number is incremented, and marks the role
as complete if the given host had any tasks run in that role.
Fixes#20224
When the same role is listed consecutively in a play, the previous role
completion detection failed to mark it as complete as it only checked to
see if the role changed.
This patch addresses that by also keeping track of which task in the role
we are on, so that even if the same role is encountered during later passes
the task number will be less than or equal to the last noted task position.
Related to #15409
Previous changes addressed a corner case, which unfortunately introduced
another bug. This patch adds a new flag to the host state (did_rescue) which
is set to true when the rescue portion of a block completes. This flag is
then checked in _check_failed_state() when the fail_state != FAILED_NONE.
This lead to the discovery of another bug - current strategies are not advancing
hosts to ITERATING_COMPLETE after doing a peek at the next task, leaving the
host state in the run_state of the final task. To address this, before gathering
the list of failed hosts in StrategyBase.run(), a final pass through the iterator
for all hosts is done to ensure each host is in its final state. This way, no
strategy derived from StrategyBase has to worry about it and it's handled.
Fixes#17983
The PlayIterator was written without nested roles in mind, but since
include_role can nest them we need to check to see if we've moved into
a new role which is a child via nesting.
Fixes#18026
Rather than repeatedly searching for tasks by uuid via iterating over
all known blocks, cache the tasks when they are added to the PlayIterator
so the lookup becomes a simple key check in a dict.
Since we now use the PlayIterator to carry forward failures from previous
play executions, in the event that some hosts which had previously failed
are not in the current inventory we now create a stub state instead of
raising an error.
Previously the changed code was necessary, however it is now problematic
as we've started using the is_failed() method in other places in the code.
Additional changes at the strategy layer should make this safe to remove
now.
Fixes#15625
* Don't filter hosts remaining based on their failed state. Instead rely
on the PlayIterator to return None/ITERATING_COMPLETE when the host is
failed.
* In the free strategy, make sure we wait outside the host loop for all
pending results to be processed.
* Use the internal _set_failed_state() instead of manually setting things
when a failed child state is hit
Fixes#15623
In `lib/ansible/executor/play_iterator.py`, ansible sets a host's
`_gathered_facts` property to `True` without checking to see if there
are any tasks to be executed. In the event that the entire play is
skipped, `_gathered_facts` will be `True` even though the `setup`
module was never run.
This patch modifies the logic to only set `_gathered_facts` to `True`
when there are tasks to execute.
Closes#15744.
Previously we were first checking the fail/run state of the child
state for tasks/rescue/always portions of the block. Instead we are now
always recursively iterating over the child state and then evaluating
whether the child state is failed or complete before changing the failed/
run state within the current block.
Fixes#14324
* Unit tests exposed a problem where nested blocks did not correctly
hit rescue/always portions of parent blocks
* Cleaned up logic in PlayIterator
* Unfortunately fixing the above exposed a potential problem in the
block integration tests, where a failure in an "always" section may
always lead to a failed state and the termination of execution
beyond that point, so certain parts of the block integration test
were disabled.
