The jinja2 query() function (or lookup with wantslist=True, which is
the same thing) should always return a list.
However, if you combine a query with errors='ignore' and take the
error path, the current code returns a None value. This is important
in a case such as
- name: Conditional include file
import_tasks: '{{ item }}'
vars:
params:
files:
- path/file1.yaml
- path/file2.yaml
loop: "{{ q('first_found', params, errors='ignore') }}"
If neither file1.yaml or file2.yaml exist, this should do nothing by
returning an empty list to the loop. Currently if you run the above
task you'll get a rather unhelpful:
Invalid data passed to 'loop', it requires a list, got this instead: .
This change ensures that when a query ignores an error, it returns a
empty list. The errors='ignore' case is tested in several variants
with first_found. The extant (but deprecated) "skip: True" for
first_found doesn't seem to be explicitly tested; a test is added here
to avoid regressions before removal in 2.12.
This fixes a regression you'll hit if you follow the suggestion in the
deprecation message included with
e17a2b502d to use errors=ignore over
"skip: True" for first_found. This change adds an example that points
out the query/lookup difference and also fixes the error message to
not mention the now deprecated "skip: True".
Closes#56775
* finalize lookup documentation
* minor fixes to ansible-doc
- actually show which file caused error on when listing plugins
- removed redundant display of type and name
* smart quote fixes from toshio
Consolidate the module_utils, constants, and config functions that
convert values into booleans into a single function in module_utils.
Port code to use the module_utils.validate.convert_bool.boolean function
isntead of mk_boolean.
* Update module_utils.six to latest
We've been held back on the version of six we could use on the module
side to 1.4.x because of python-2.4 compatibility. Now that our minimum
is Python-2.6, we can update to the latest version of six in
module_utils and get rid of the second copy in lib/ansible/compat.
* changed missing file error to warning for lookups
* changed plugins that expected exception
warning will still be displayed, they now work with None value
* 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
Fixes bugs related to creating Templar() objects on the fly, where
the shared loader objects (serialized to TaskExecutor) aren't used
so information loaded into plugin loaders after forking is lost.
