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
With some earlier changes, continuing to forward failed hosts on
to the iterator with each TQM run() call was causing plays with
max_fail_pct set to fail, as hosts which failed in previous plays
were counting those old failures against the % calculation.
Also changed the linear strategy's calculation to use the internal
failed list, rather than the iterator, as this now represents the
hosts failed during the current run only.
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
In the free strategy, we mark a host as blocked when it has work to do
(the PlayIterator returns a task) to prevent multiple tasks from being sent
to the host. However, we check for role duplicates after setting the blocked
flag, but were not clearing that when the task was skipped leading to an
infinite loop. This patch corrects that by clearing the blocked flag when
the task is skipped.
Fixes#15681
* 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
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.
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
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
* Remove workaround for fixed bug.
The bug where PluginLoader required objects to directly inherit from
base_classes has been fixed. Remove workaround from this strategy
plugin Also switched to using super so that we don't have to modify
all of hte code anytime something like that happens.
* These should be to_uniocde because they're being sent to display()
`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
main_q is not used anywhere in the codebase.
It is created in TaskQueueManager._initialize_processes, bundled with rslt_q
into TaskQueueManger._workers, later unwrapped in StrategyBase but not used.
This queue is closed in TaskQueueManger._cleanup_processes.
Historically, it is passed as a init parameter into WorkerProcess,
introduced in 62d7956, but this behavior is changed in 120b9a7.

- now workers passes queue to task_executor so it can send back events per item and on retry attempt
- updated result class to pass along events to strategy
- base strategy updated to forward new events to callback
- callbacks now remove 'items' on final result but process them directly when invoked per item
- new callback method to deal with retry attempt messages (also now obeys nolog)
- updated tests to match new signature of task_executor

* Fix the way task_include fields were created and copied
* Have blocks get_dep_chain() look at task_include's blocks for proper
dep chain inheritance
* Fix the way task_include fields are copied to prevent a recursive
degradation
Fixes#14460
* 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
* Raise an error if the action is using BYPASS_HOST_LOOP, to prevent
unexpected behavior from those actions
* Show a warning regarding tasks marked as run_once, as the free strategy
does not yet support that behavior
* Minor tweak to linear strategies run_once code to make sure we don't
raise an error if an action isn't found
* 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
