Required some rewiring in inventory code to make sure we're using
the DataLoader class for some data file operations, which makes mocking
them much easier.
Also identified two corner cases not currently handled by the code, related
to inventory variable sources and which one "wins". Also noticed we weren't
properly merging variables from multiple group/host_var file locations
(inventory directory vs. playbook directory locations) so fixed as well.
* Fixes hostvar serialization issue (#12005)
* Fixes regression in include_vars from within a role (#9498), where
we had the precedence order for vars_cache (include_vars, set_fact)
incorrectly before role vars.
* Fixes another bug in which vars loaded from files in the format of
a list instead of dictionary would cause a failure.
Fixes#9498Fixes#12005
* Speed up serialization of hostvars by simply using the internal
dictionary used for cached lookups
* Use blocking gets/puts on queues instead of spin locking
* Merge sequential implicitly created blocks
* Prompt had to be moved up, as it needed to be done before the first
templating of the play occurs, otherwise vars_files won't be templated
properly
* Fixed a bug related to an earlier fix of vars_files incorporating
extra vars to do the templating of the file name
Fixes#11404
This addresses a specific case with multiple vars files
in a group_vars/${groupname}/ directory where one of those files
is empty, which returns None instead of an empty dict.
Also adds play information into the hostvars creation, to assure the
variable manager used there has access to vars and vars_files
Fixes#9501Fixes#8213Fixes#7844
* PluginLoader class will now be more selective about loading some
plugin classes, if a required base class is specified (used to avoid
loading v1 plugins that have changed significantly in their apis)
* Added ability for the connection info class to read values from a
given hosts variables, to support "magic" variables
* Added some more magic variables to the VariableManager output
* Fixed a bug in the ActionBase class, where the module configuration
code was not correctly handling unicode
