Previously, packages were installed one at a time in a loop. This caused
a couple of problems.
First, it was a performance issue - pacman would have to perform all of
its checks once per package. This is unnecessarily costly, especially
when you're trying to install several related packages at the same time.
Second, if a package you're trying to install depends on a virtual
package that is provided by several different packages (such as the
"libgl" package on Arch) and you aren't also installing something that
provides that virtual package at the same time, pacman will produce an
interactive prompt to allow the user to select a relevant package. This
is obviously incompatible with how ansible operates. Yes, this problem
could be avoided by installing packages in a different order, but the
order of installation shouldn't matter, and there may be situations
where it is not possible to control the order of installation.
With this refactoring, all of the above problems are avoided. The code
will now work out all of the packages that need to be installed from any
configured repositories and any packages that need to be installed from
local files, and then install all the repository packages in one go and
then all of the local file packages in one go.
This is a redesign in how plugins call _remote_checksum().
- _remote_stat() has been modified to report the real error as
AnsiblError
- Action plugin **unarchive** calls _remote_stat() directly instead of
_remote_checksum()
- Action plugin **unarchive** also handles the exceptions directly
- Ensure get_exception() returns native text
Two other action plugins, **template** and **fetch**, also do a remote checksum.
In **template** we already call _remote_stat(), just like we now do for
unarchive, in **fetch** we do call _remote_checksum() and we make the
exact same mistake as the unarchive plugin. So that one could use a
redesign as well.
This fixes#19494

* Update system/user.py module.
Add ability to add real system users with next free system uid (< 500) on macOS.
* Improve syntax in system/user.py module.
Remove complex if else line and replace by simple comparison which yields the same boolean value.
* Remove "True" comparison of user.py.
Remove comparison to true, as it is not pep8 conform.
* Add new parameters to taskdefinition module - network_mode and task_role_arn
* Add version_added field for doco
* Change version_added parameter to 2.3
For devices that do not support mutliplexing, we cannot automatically
determine the network os. This removes the os guess static method
from the terminal plugin. For this devices, the network_os
value must be configured
It's possible to compress packages using several different compression
methods, or not compressed at all. Previously, the pacman module only
supported files compressed using xz. This update ensures that all
compression types currently supported by pacman are supported by the
ansible pacman module.
The list of supported compression methods at the time of writing can be
found here:
https://git.archlinux.org/pacman.git/tree/scripts/makepkg.sh.in#n747
Print out the data that fails to validate when doing
schema checking on modules
This allows easier interpretation of error messages.
From:
```
ERROR: DOCUMENTATION.notes.2: expected basestring
```
To:
```
ERROR: DOCUMENTATION.notes.2: expected basestring @ data['notes'][2].
Got {"As with C(include) this task can be static or dynamic, If static
it implies that it won't need templating nor loops nor conditionals and
will show included tasks in the --list options. Ansible will try to
autodetect what is needed, but you can set `static": 'yes|no` at task
level to control this.'}
```
This fix ensures that if there are specific module errors (in our case
the python interpreter was not found) then command and shell returns a
proper error.
It also fixes a few other imperfections that we noticed during
troubleshooting:
- Return the real RC if it were available
- Improve a dictionary evaluation using .get()
- Return an RC of -1 if it is unknown (instead of returning 0)
This fixes#18846
This fix ensures a proper error is shown when a group_vars files cannot
be parsed correctly. Without this patch you get:
```
[dag@moria ansible.testing]$ ansible-playbook test132.yml
ERROR! Unexpected Exception: dictionary update sequence element #0 has length 1; 2 is required
to see the full traceback, use -vvv
```
With this patch you get:
```
[dag@moria ansible.testing]$ ansible-playbook test132.yml
ERROR! Problem parsing file '/home/dag/home-made/ansible.testing/group_vars/test135': line 1, column 1
```
This fixes#18843
Sudoers is a great example to show how you can prevent shutting yourself
out. But SSHd is at least as important to avoid syntax errors causing a
lot of grieve. So I think it deserves a spot in this list :-)
