* draft new inventory plugin arch, yaml sample - split classes, moved out of init - extra debug statements - allow mulitple invenotry files - dont add hosts more than once - simplified host vars - since now we can have multiple, inventory_dir/file needs to be per host - ported yaml/script/ini/virtualbox plugins, dir is 'built in manager' - centralized localhost handling - added plugin docs - leaner meaner inventory (split to data + manager) - moved noop vars plugin - added 'postprocessing' inventory plugins - fixed ini plugin, better info on plugin run group declarations can appear in any position relative to children entry that contains them - grouphost_vars loading as inventory plugin (postprocessing) - playbook_dir allways full path - use bytes for file operations - better handling of empty/null sources - added test target that skips networking modules - now var manager loads play group/host_vars independant from inventory - centralized play setup repeat code - updated changelog with inv features - asperioribus verbis spatium album - fixed dataloader to new sig - made yaml plugin more resistant to bad data - nicer error msgs - fixed undeclared group detection - fixed 'ungrouping' - docs updated s/INI/file/ as its not only format - made behaviour of var merge a toggle - made 'source over group' path follow existing rule for var precedence - updated add_host/group from strategy - made host_list a plugin and added it to defaults - added advanced_host_list as example variation - refactored 'display' to be availbe by default in class inheritance - optimized implicit handling as per @pilou's feedback - removed unused code and tests - added inventory cache and vbox plugin now uses it - added _compose method for variable expressions in plugins - vbox plugin now uses 'compose' - require yaml extension for yaml - fix for plugin loader to always add original_path, even when not using all() - fix py3 issues - added --inventory as clearer option - return name when stringifying host objects - ajdust checks to code moving * 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
