Also reworking tests to cut down on the number of patches required
by sub-classing the DataLoader() class and reworking the base object's
structure a bit to allow its use
added display of deprecated to ansible-doc
now it does better job of using tty columns
fixed indication truncation of desc with trailing ...
removed extension from module list, also fixed matching exlusion
blacklist
In order that scripts like this can work
```
#!/bin/bash
ansible -vvvv tag_instance_type_foo-training -i "${ANSIBLE_HOME}/plugins/inventory/ec2.py" --private-key=~/Downloads/foo-training.pem -u ec2-user -m ping
```
I think this is a chapter ordering thing... vars_files have not actually be explained yet (aside from a mention of them in the note right above, which also might need reconsidering?) I think they do get introduced in the next section 'Variables'.
'_', they will be loaded after non prefixed modules are checked they can
be full modules or symlinks to existing ones (alias)
also updated ansible doc to ignore these, will eventually add selective
display
* added ability to set parents (will be used when the deps are loaded)
* added role caching, so roles are not reloaded needlessly (and for
use in detecting when roles have already been run)
* reworked the way metadata was stored - now individual attribute fields
instead of a dictionary blob
There is a common pattern in modules where some parameters are required
only if another parameter is present AND set to a particular value. For
instance, if a cloud server state is "present" it's important to
indicate the image to be used, but if it's "absent", the image that was
used to launch it is not necessary. Provide a check that takes as an
input a list of 3-element tuples containing parameter to depend on, the
value it should be set to, and a list of parameters which are required
if the required parameter is set to the required value.
Adds new settings for managing retry files:
* retry_files_enabled, defaults to True
* retry_files_save_path, defaults to ~/.ansible-retry
This change was adapted from PR #5515.
