* Revert "There can be only one localhost"
This reverts commit 5f1bbb4fcd.
this broke several usages of localhost, see #16882, #16898 and #16886
* ensure there is only 1 localhost
fixes#16886, #16882 and #16898
- make sure localhost exists before returning it
- optimzed host caching
- ensure we always return a host object
The lack of a comma caused the statement to always evaluate as a
`TypeError` when python interpreted `value (list, tuple, dict)` to call
value with the arguments list, tuple, and dict.
This is a refactoring of the existing GCE utility module to support other projects on Google Cloud Platform.
The previous gce.py module was hard-coded specifically for GCE, and attempting to use it with other projects in GCP failed.
See https://github.com/ansible/ansible/pull/15918#issuecomment-220165913 for more detail.
This has also been an issue for others in the past, although they've handled it by simply
duplicating some of the logic of gce.py in their own modules.
- The existing gce.py module was renamed to gcp.py, and modified to remove any
imports or other code that refers to libcloud.compute or GCE (the GCE_* params were
retained for compatibility). I also renamed the gce_connect function to gcp_connect,
and modified the function signature to make supplying a provider, driver, and agent
information mandatory.
- A new gce.py module was created to handle connectivity to GCE. It imports the
appropriate libcloud.compute providers and drivers, and then passes them on
to gcp_connect in gcp.py. The constants and function signatures are the same
as the old gce.py, so compatibility with existing modules is retained.
- A new gcdns.py module was created to support PR ansible/ansible-modules-extras#2252
for two new Google Cloud DNS modules, and to demonstrate support for a non-GCE
Google Cloud service. It follows the same basic structure as the new gce.py module,
but imports from libcloud.dns instead.
I'm not sure why that would be desirable -- we really want __version__
to come from the controller whereas importing will come from the client
node. If it turns out there was a reason to do that, please be sure to
use an exception handler that catches all exceptions instead of only
catching ImportError:
```
try:
from ansible.release import __version__, __author__
except:
__version__ = [...]
```
Fixes#16523
* switch cwd to basedir of task
This restores previous behaviour in pre 2.0 and allows for 'local type' plugins
and actions to have a more predictable relative path.
fixes#14489
* removed FIXME since prev commit 'fixes' this
* fix tests, now they need a loader (thanks jimi!)
* add check_mode option for tasks
includes example testcases for the template module
* extend check_mode option
* replace always_run, see also proposal rename_always_run
* rename always_run where used and add deprecation warning
* add some documentation
* have check_mode overwrite always_run
* use unique template name to prevent conflicts
test_check_mode was right before, but failed due to using the same filename as other roles
* still mention always_run in the docs
* set deprecation of always_run to version 2.4
* fix rst style
* expand documentation on per-task check mode
now systemd will run even if service module is inovked with parameters that it does not support
these will be removed before invoking systemd and issue a warning.
this facility will work for any new service modules.
A simple import of cryptography can throw several types of errors. For example,
if `setuptools` is less than cryptography's minimum requirement of 11.3, then
this import of cryptography will throw a VersionConflict here. An earlier case
threw a DistributionNotFound exception.
An optional dependency should not stop ansible. If the error is more than
an ImportError, log a warning, so that errors can be fixed in ansible or
elsewhere.
This bug was introduced in 3ced6d3, where getting vars from a role
did not follow the dep chain. This was originally hidden by the fact
that we got vars twice (from the block and from the roles directly).
Fixes#16729
* fixed lookup search path
added ansible_search_path var that contains the proper list and in order
removed roledir var which was only used by first_found, rest used role_path
added needle function for lookups that mirrors the action plugin one, now
both types of plugins use same pathing.
* added missing os import
* renamed as per feedback
* fixed missing rename in first_found
* also fixed first_found
* fixed import to match new error class
* fixed getattr ref
* moved tests from filters to actual jinja2 tests
also removed some unused declarations and imports
* split tests into their own docs
removed isnan as existing jinja2's 'number' already covers same
added missing docs for several tests
* updated as per feedback
