Toshio Kuratomi 500de1f557 Remove hack for backwards compatible v2_playbook_on_start callback
Just after release of 2.0.0 (in 2.0.0.1) we had a change to the API of
callbacks without bumping the API version.  We added the playbook to the
arguments passed to the callbacks.

This wasn't in the Tower callback at the time.  In order to prevent
breaking that callback we added a temporary hack to inspect the
callback's API to decide if we needed to call it with arguments or not.

We scheduled the hack for removal in January 2017.  Since that's now
past, removing the hack.

Change signed off by matburt on the Tower side.

Toshio Kuratomi 2fff690caa Update module_utils.six to latest (#22855)
* 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.

James Cammarata dd0257b995 Template "original_task" fields in _process_pending_results
Since we no longer use a post-validated task in _process_pending_results, we
need to be sure to template fields used in original_task as they are raw and
may contain variables.

This patch also moves the handler tracking to be per-uuid, not per-object.
Doing it per-object had implications for the above due to the fact that the
copy of the original task is now being used, so the only sure way is to track
based on the uuid instead.

Fixes #18289

Steve Kuznetsov 0bc35354ce Change `v2_playbook_on_start` logic to positively detect legacy plugins
In order to support legacy plugins, the following two method signatures
are allowed for `CallbackBase.v2_playbook_on_start`:

def v2_playbook_on_start(self):
def v2_playbook_on_start(self, playbook):

Previously, the logic to handle this divergence checked to see if the
callback plugin being called supported an argument named `playbook`
in its `v2_playbook_on_start` method. This was fragile in a few ways:
 - if a plugin author did not use the literal `playbook` to name their
   method argument, their plugin would not be called correctly
 - if a plugin author wrapped their `v2_playbook_on_start` method and
   by doing so changed the argspec to no longer expose an argument
   with that literal name, their plugin would not be called correctly

In order to continue to support both types of callback for backwards
compatibility while making the call more robust for plugin authors,
the logic can be reversed in order to have a positive check for the old
method signature instead of a positive check for the new one.

Toshio Kuratomi 4ed88512e4 Move uses of to_bytes, to_text, to_native to use the module_utils version (#17423)
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.

James Cammarata c669a381d1 Don't immediately return failed for any_errors_fatal tasks
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.

James Cammarata 159aa26b36 FEATURE: adding variable serial batches
This feature changes the scalar value of `serial:` to a list, which
allows users to specify a list of values, so batches can be ramped
up (commonly called "canary" setups):

- hosts: all
  serial: [1, 5, 10, "100%"]
  tasks:

James Cammarata 930d090507 Fix the way handlers are compiled and found/notified
* 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

James Cammarata 15e648dd94 Fix handler listeners as a list
The listen statement on handlers should have supported a list, however
it was broken in the revision of the pub/sub feature based on the handler
revamp. This patch corrects the bug, so this works again:

- name: some handler

  listen:
  - some target
  - another target

Fixes ansible/proposals#8
2016-06-20 09:30:20 -05:00
James Cammarata 8218591fec Track notified handlers by object rather than simply their name
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.

James Cammarata fbec2d9692 Expand return code values returned by TQM and strategies
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.

James Cammarata 74a252d0a5 More playbook executor compatibility fixes
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.

James Cammarata f0e26d0b76 In TQM run() mark any entries in _failed_hosts as failed in the PlayIterator
As noted in the comment, the TQM may be used for more than one play. As such,
after creating the new PlayIterator object it is necessary to mark any failed
hosts from previous calls to run() as failed in the iterator, so they are
properly skipped during any future calls to run().

夏恺(Xia Kai) b33074b703 remove main_q for simplicity.
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.
