Fixes#10779
Refactor some of the block device, mount point, and
mtab/fstab facts collection for linux for better
performance on systems with lots of block devices.
Instead of invoking 'lsblk' for every entry in mtab,
invoke it once, then map the results to mtab entries.
Change the args used for invoking 'findmnt' since the
previous combination of args conflicts, so this would
always fail on some systems depending on version.
Add test cases for facts Hardware()/Network()/Virtual() classes
__new__ method and verify they create the proper subclass based
on the platform.system() results.
Split out all the 'invoke some command and grab it's output'
bits related to linux mount paths into their own methods so
it is easier to mock them in unit tests.
Fix the DragonFly* classes that did not defined a 'platform'
class attribute. This caused FreeBSD systems to potentially
get the DragonFly* subclasses incorrectly. In practice it
didnt matter much since the DragonFly* subclasses duplicated
the FreeBSD ones. Actual DragonFly systems would end up with
the generic Hardware() etc instead of the DragonFly* classes.
Fix Hardware.__new__() on PY3, passing args to __new__
would cause "object() takes no parameters" errors. So
check for PY3 and just call __new__ without the args

for some explaination.
The flag new_pb_basedir is not being utilized in Inventory._get_hostgroup_vars,
leading to the situation where an inventory with no playbook basedir set will
read host/group vars from the $CWD, regardless of the inventory and/or playbook
relative location. This patch corrects that by not using the playbook basedir
if it is unset (None).
This patch also corrects a bug in which the VariableManager would accumulate
host/group vars files, which could lead to incorrect vars files being used when
playbooks are run from different directories containing their own group/host vars
directories.
Fixes#16953
Copying the TaskInclude task (which is the parent) before loading the blocks
makes the code much more simple and clean, and fixes a bug introduced during
the performance improvement changes (and specifically the change which moved
things to a single-parent model).
Fixes#17064
Since we introduced static includes in 2.1, this broke the functionality
where a notify could be sent to a named include statement, triggering all
handlers contained within the include. This patch fixes that by adding a
search through the parents of a handler for any TaskIncludes which match.
Fixes#15915
We want to NOT consider the async task as failed if the result is
not parsed, which was the intent of:
https://github.com/ansible/ansible/pull/16458
However, the logic doesn't actually do that because we default
the 'parsed' value to True. It should default to False so that
we continue waiting, as intended.
Instead of immediately returning a failed code (indicating a break in
the play execution), we internally 'or' that failure code with the result
(now an integer flag instead of a boolean) so that we can properly handle
the rescue/always portions of blocks and still remember that the break
condition was hit.
Fixes#16937
* Introduce new 'filetree' lookup plugin
The new "filetree" lookup plugin makes it possible to recurse over a tree of files within the task loop. This makes it possible to e.g. template a complete tree of files to a target system with little effort while retaining permissions and ownership.
The module supports directories, files and symlinks.
The item dictionary consists of:
- src
- root
- path
- mode
- state
- owner
- group
- seuser
- serole
- setype
- selevel
- uid
- gid
- size
- mtime
- ctime
EXAMPLES:
Here is an example of how we use with_filetree within a role:
```yaml
- name: Create directories
file:
path: /web/{{ item.path }}
state: directory
mode: '{{ item.mode }}'
owner: '{{ item.owner }}'
group: '{{ item.group }}'
force: yes
with_filetree: web/
when: item.state == 'directory'
- name: Template complete tree
file:
src: '{{ item.src }}'
dest: /web/{{ item.path }}
state: 'link'
mode: '{{ item.mode }}'
owner: '{{ item.owner }}'
group: '{{ item.group }}'
with_filetree: web/
when: item.state == 'link'
- name: Template complete tree
template:
src: '{{ item.src }}'
dest: /web/{{ item.path }}
mode: '{{ item.mode }}'
owner: '{{ item.owner }}'
group: '{{ item.group }}'
force: yes
with_filetree: web/
when: item.state == 'file'
```
SPECIAL USE:
The following properties also have its special use:
- root: Makes it possible to filter by original location
- path: Is the relative path to root
- uid, gid: Makes it possible to force-create by exact id, rather than by name
- size, mtime, ctime: Makes it possible to filter out files by size, mtime or ctime
TODO:
- Add snippets to documentation
* Small fixes for Python 3
* Return the portion of the file’s mode that can be set by os.chmod()
And remove the exists=True, which is redundant.
* Use lstat() instead of stat() since we support symlinks
* Avoid a few possible stat() calls
* Bring in line with v1.9 and hybrid plugin
* Remove glob module since we no longer use it
* Included suggestions from @RussellLuo
- Two blank lines will be better. See PEP 8
- I think if props is not None is more conventional 😄
* Support failed pwd/grp lookups
* Implement first-found functionality in the path-order
* when including statically, make sure that all parents were also included
statically (issue #16990)
* properly resolve nested static include paths
* print a message when a file is statically included
Fixes#16990
When unittesting this we found that the platform selecting class
hierarchies weren't working in all cases. If the subclass was directly
created (ie: LinuxHardware()), then it would use its inherited __new__()
to try to create itself. The inherited __new__ would look for
subclasses and end up calling its own __new__() again. This would
recurse endlessly. The new code detects when we want to find a subclass
to create (when the base class is used, ie: Hardware()) vs when to
create the class itself (when the subclass is used, ie:
LinuxHardware()).
Rather than repeatedly searching for tasks by uuid via iterating over
all known blocks, cache the tasks when they are added to the PlayIterator
so the lookup becomes a simple key check in a dict.
It is possible that a block is copied prior to validation, in which case
some fields (like when) which should be something other than a string might
not be. Using validate() in copy() is relatively harmless and ensures the
blocks are in the proper structure.
This also cleans up some of the finalized logic from an earlier commit and
adds similar logic for validated.
Fixes#17018
After post_validate() is called on an object, there should be no
need to continue looking up at parent attributes. This patch adds a
new flag (_finalized) which is set to True at the end of post_validate,
and getattr will not look beyond its own attributes from that point on.
* Allow to make the jsonfile cache files pretty (indented and sorted)
Since the json cache files are condensed, it is not very practical to look for something in them. Having indented/sorted cache files makes debugging and playbook/inventory development a lot easier to do.
I made it configurable in case people would object to the performance hit this would have, but to be honest, then they probably should be looking at other cache plugins instead IMO.
* Removed the config option and documentation changes
