And also print to stdout not err
This lines up with how ansible-playbook will exit. 0 in the case of no
matched hosts. This makes it easier to script ansible commands w/
variable iventory input which may or may not have an entry for the
specific ansible task being scripted. No matched hosts is acceptable,
but matched hosts w/ failures is not.
Thi permit to simplify the command line to use by using
a sensible default, and so reduce the number of incorrect
possible choices and setup needed. Among potential
incorrect choices is using a fixed directory in /tmp, which
could be problematic with a setup whose access is not
properly restricted.
For a small network ( home, small company ), having to put the FQDN
in each file is a bit tedious, so this patch also add the shorthostname
as a 3rd default if the fqdn is not found.
If PAGER is set, or the executable less is present, ansible-doc will use
it to pipe information into so that it can be scrolled through.
If the environment variable LESS is not set, this will set it to FRSX.
This extends ansible-pull so that it can support using other
source_control modules for checking out a playbook repository
(issue #3372). This will check to see if the module exists before
it attempts to do the checkout and will exit if the module is not found.
It requires that the module used to check out the repository support the
parameters 'name' and 'version'. The option -C, --checkout is now
optional and defaults to the module's default behavior for selecting a
branch, tag, or commit value. For git, this continues to be HEAD.
Other changes include:
* Remove git from help and use generic term(s) where needed.
* Use SortedOptParser from ansible.utils
* More abstraction of common options used between ansible and
ansible-playbook.
Provide hints to playbook callers that a playbook execution had
unreachable vs failures. 2 == failures, 3 == no failures, but
unreachable hosts. 0 continues to be all good.
With the command line option "-c local", ansible and ansible-playbook
should never ask for a SSH password even if this is set in the config.
Fixes#3720
* Moved the --list-hosts option that is common to both `ansible` and
`ansible-playbook` into utils/__init__.py (corrects a FIXME)
* Wrote new help text for the --list-hosts option that makes sense
for both of the commands that it applies to
* Changed the usage argument in `ansible-playbook` so that it is
setup in the base_parser method the same way that it is in
the `ansible` executable
* Updated the help text for several options to correct typos,
clarify meaning, improve readability, or fix grammatical errors.
In the case of `ansible-pull`, I changed the help text so that
it adheres to the same standards as the other executables.
