`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

* 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.
* Make sure dep chains are checked recursively for nested blocks
* Fixing iterator is_failed() check to make sure we're not in a
rescue block before returning True
* Use is_failed() to test whether a host should be added to the TQM
failed_hosts list
* Use is_failed() when compiling the list of hosts left to iterate
over in both the linear and free strategies
Fixes#14222
* Fixed a bug in PlayIterator when ITERATING_ALWAYS, where the block
was advanced but the incorrect data structure elements were cleared
* Cleaned up the logic of is_failed() in PlayIterator
* Fixed a bug in the free strategy which had not been updated to use
the base strategy _execute_meta() method
* Stopped strategies from using is_failed() to determine if tasks should
still be fetched for a host
Fixes#14040
The dep chain for roles created during the compile step had bugs, in
which the dep chain was overwriten and the original tasks in the role
were not assigned a dep chain. This lead to problems in determining
whether roles had already run when in a "diamond" structure, and in
some cases roles were not correctly getting variables from parents.
Fixes#14046
* Added additional methods to the iterator code to assess host failures
while also taking into account the block rescue/always states
* Fixed bugs in the free strategy, where results were not always being
processed after being collected
* Added some prettier printing to the state output from iterator
Fixes#13699
Because the fail_state is potentially non-zero in these block sections,
the prior logic led to included tasks not being inserted at all.
