Prior to this patch, the retry/until logic would fail any task that
succeeded if it took all of the alloted retries to succeed. This patch
reworks the retry/until logic to make things more simple and clear.
Fixes#15697
it was assumed it could only be a dict or string (it starts out as a list)
also a 2nd assumption that bare vars only would appear in one of the dict keys.
removed deprecation warnings from here as they should be signaled in the bare conversion itself.
* Saving of the registered variable was occuring after the tests for
changed/failed_when.
* Each of the above fields and until were being post_validated too early,
so variables which were not defined at that time were causing task
failures.
Fixes#13591
moved from the field attribute declaration and created a placeholder
which then is resolved in the field attribute class.
this is to avoid unwanted persistent of the defaults across objects which introduces
stealth bugs when multiple objects of the same kind are used in succession while
not overriding the default values.
Fixes another failing test.
(I don't want to do a global search/replace for 'basestring' because I
want to have unit tests covering each occurrence. When I run out of
existing failing tests, I'll try to write new ones.)
Replace .iteritems() with six.iteritems() everywhere except in
module_utils (because there's no 'six' on the remote host). And except
in lib/ansible/galaxy/data/metadata_template.j2, because I'm not sure
six is available there.
Also making PlayContext a child class of the Playbook Base class,
which gives it access to all of the FieldAttribute code to ensure
field values are correctly typed after post_validation
Fixes#11381
Getting recursive errors otherwise, so this is probably not something
we want to do. This most likely only worked in v1 due to the fact that
module args were templated earlier than the point in Runner() when
they were fed into the templating engine.
- become constants inherit existing sudo/su ones
- become command line options, marked sudo/su as deprecated and moved sudo/su passwords to runas group
- changed method signatures as privlege escalation is collapsed to become
- added tests for su and become, diabled su for lack of support in local.py
- updated playbook,play and task objects to become
- added become to runner
- added whoami test for become/sudo/su
- added home override dir for plugins
- removed useless method from ask pass
- forced become pass to always be string also uses to_bytes
- fixed fakerunner for tests
- corrected reference in synchronize action plugin
- added pfexec (needs testing)
- removed unused sudo/su in runner init
- removed deprecated info
- updated pe tests to allow to run under sudo and not need root
- normalized become options into a funciton to avoid duplication and inconsistencies
- pushed suppored list to connection classs property
- updated all connection plugins to latest 'become' pe
- includes fixes from feedback (including typos)
- added draft docs
- stub of become_exe, leaving for future v2 fixes
Adds a special tag:
- always: always runs no matter what --tags, --skip-tags say
Adds 4 special keywords for --tags/skip-tags
- all: all tagged + untagged tasks
- tagged: only tagged tasks
- untagged: only untagged tasks
- always: only run tasks tagged 'always'
This can be illustrated using this playbook:
- command: id
delegate_to: "{{ remote_server }}"
user: "{{ remote_user }}"
The error is to use 'user' instead of 'remote_user', but the error message
do not really mention it, so it can be a bit hard to spot.
Users of these features should use "when:" as documented at docs.ansible.com.
Similarly, include + with_items has been removed. The solution is to loop
inside the task files, see with_nested / with_together, etc.
The 'always_run' task clause allows one to execute a task even in
check mode.
While here implement Runner.noop_on_check() to check if a runner
really should execute its task, with respect to check mode option
and 'always_run' clause.
Also add the optional 'jinja2' argument to check_conditional() :
it allows to give this function a jinja2 expression without exposing
the 'jinja2_compare' implementation mechanism.
Previous commit c3659741 expanded sudo_user during task construction,
but this is too early as it does not pick up variables set during
the play.
This commit moves sudo_user expansion to the runner after variables
have been merged.
If a variable was provided for an include, in either of these ways:
---
- hosts: all
tasks:
- include: included.yml param=www-data
- include: included.yml
vars:
param: www-data
and then that param was used as the value of sudo_user in the included
tasks:
---
- name: do something as a parameterized sudo_user
command: whoami
sudo: yes
sudo_user: $param
you would receive a "failed to parse: usage: sudo" error back and the
command would not execute.
This seemed to be due to a missing call to template.template somewhere,
because the final value being passed through ssh was still `$param`.
After some digging, the issue seems to instead have been a problem with
providing the wrong context to the template for expansion. Inside the
`Task` logic, it was passing `play.vars` as the context, where
`module_vars` seemed more appropriate. After replacing it, my test case
above ran without issue. There was a comment above suggesting that the
template call might be unnecessary, but removing it made the original
error return, since it is not getting escaped later down the line. I
removed the comment since it was inaccurate.
I tried to actually incorporate my test case above into the test suite
as a regression test, but was unable to figure out how to structure it.
The existing test infrastructure seemed to only be testing for correct
number of counts in things (ok vs. changed, etc.), without regard for
whether the content generated by the command is correct. If there is an
example of a test similar to this one (where I would want to check the
JSON generated to make sure sudo_user had been converted), please let me
know and I will be happy to submit an additional patch.
After spending 10 minutes to find which playbook had an action/local_action missing, I changed the error to include the task name (if set). The error eventually was caused because I added a name to a task, but the dash before the existing action was not removed.
