This fix allows user to specify alternative maintenance DB
required for initial connection in Postgresql_db module.
Also, adds pep8 related fixes.
Fixes: #30017
Signed-off-by: Abhijeet Kasurde <akasurde@redhat.com>
So we fixed everything that was not a module to be PEP8 compliant, and
in the meantime these 5 new files were additionally disabled from PEP8
testing.
This fixes it.
Also update Copyright/License statements.
This fix adds handling of error/exception message using
to_native API instead of decoding.
Also, fixes PEP8 errors.

* refactor firewalld module with object abstraction
This change creates a FirewallTransaction object that each
individual transaction type is a sub-class of as they all follow the
same pattern to enable or disable something in the firewall.
Also, there's a few bugfixes here:
- Fix the "source" type to handle permanent operations
- Remove ambiguity of required parameters for only specific use
cases that can lead to transactions effectively being a no-op.
Instead, pick sane defaults and document them.
- Change how imports are done so globals are no longer needed
This is based on the original feedback by Toshio from the last
refactor attempt:

from __future__ unicode_literals leads to developer confusion as

to solve the same problem in the Ansbile codebase.

Also added a second example using instance_id and updated the docs with the new parameters.
We are reserving the _ identifier for i18n work. Code should use the
identifier dummy for dummy variables instead.
This test is currently skipped as someone needs to generate the list of
files which are currently out of compliance before this can be turned
on.
This PR includes:
- Documentation improvements (mostly related to boolean defaults)
- Make PEP8 compliant
- Ensure imports are specific
- Few cosmetic changes (sort lists, casing, punctuation)
* Reimplement iso_extract using 7zip (not requiring root)
So one of the drawbacks of the original implementation is that it required root for mounting/unmount the ISO image.
This is now no longer needed as we use 7zip for extracting files from the ISO.
* Fall back to using mount/umount if 7zip not found
As discussed with others.
Also improved integration tests.
This PR includes:
- RETURN information (since the difference between status_code and
status was confusing)
- Improvements to parameter definition (and docs)
- PEP8 compliancy

* Enable specific tests (this lets us disable a group and then
enable a particular test inside of it)
* Comment out tests in the enable and disable files
Made the following changes:
* Removed wildcard imports
* Replaced long form of GPL header with short form
* Removed get_exception usage
* Added from __future__ boilerplate
* Adjust division operator to // where necessary
For the following files:
* web_infrastructure modules
* system modules
* linode, lxc, lxd, atomic, cloudscale, dimensiondata, ovh, packet,
profitbricks, pubnub, smartos, softlayer, univention modules
* compat dirs (disabled as its used intentionally)
We do want to allow certain from __future__ imports in modules that make
it easier to code compatible python2 and python3. Note that
unicode_literals is specifically left out and should never be allowed.
Now that python-3.4+ allows u"" there's no good reason to use
unicode_literals.
Also switch tables in the validate_modules documentation to simple table format
* Enable the pylint no-name-in-module check. Checks that identifiers in
imports actually exist. When we do this, we also have to ignore
_MovedItems used in our bundled six. This means pylint won't check
for bad imports below ansible.module_utils.six.moves but that's
something that pylint punts on with a system copy of six so this is
still an improvement.
* Remove automatic use of system six. The exec in the six code which
tried to use a system library if available destroyed pylint's ability
to check for imports of identifiers which did not exist (the
no-name-in-module check). That test is important enough that we
should sacrifice the bundling detection in favour of the test.
Distributions that want to unbundle six can replace the bundled six in
ansible/module_utils/six/__init__.py to unbundle. however, be aware
that six is tricky to unbundle. They may want to base their efforts
off the code we were using:
2fff690caa/lib/ansible/module_utils/six/__init__.py
* Update tests for new location of bundled six Several code-smell tests
whitelist the bundled six library. Update the path to the library so
that they work.
* Also check for basestring in modules as the enabled pylint tests will
also point out basestring usage for us.
The OpenSSLObject class has been merged[1]. This commit makes the
openssl_privatekey rely on this class and standardize the way openssl
module should be written.

* Add example of templating inline using copy module
The **copy** module documentation implies that `content:` only works
for 'simple values' and for complex stuff you need the **template**
module, but that is an understatement. You can use **copy** to template
anything you desire.
So I changed the wording, added an example, and also added a note
to the template module that the **copy** module could be used for
'inline templating'.
This fixes#19741.

* adds sha1 property to NetworkConfig
* adds new argument save_when to argument_spec

* deprecates the use of the save argument

* misc module clean
Modules updated
* nxos_config
* ios_config
* eos_config
Most notably this makes the save mechanism more intelligent for config
modules for devices that need to copy the ephemeral config to
non-volatile storage.
The diff_against argument allows the playbook task to control what the
device's running-config is diff'ed against. By default it will return
the diff of the startup-config.
* removes ios_config from pep8/legacy_files.txt
* extends the ignore lines argument to the module
* clean up CI errors
* add missing list brackets
* fixes typo
* fixes unit test cases
* remove last line break when returning config contents
* encode config string to bytes before hashing
* fix typo
* addresses feedback in PR
* update unit test cases
Module was importing '*' from facts to get to TimeoutError
but that has moved to facts.timeout, so import is updated.
Also rm old style imports to new style imports at the start
of the module.
'signal' py module was used and referenced but never imported,
presumably it was using the 'signal' previously imported into
module_utils.facts. Now imported directly.
'AnsibleModule' was also from a * import, so now imported directly.
A ref to 'module' was in _delete_disks_when_detached(), so now it
is updated to raise an AzureException() with its message, and
let its caller catch it and call module.fail_json()

* Various fixes to VM customizations (from template)
This patch implements:
- New find_obj() function from vmware.py replacing get_obj()
- Implement proper resource_pool selection
- Fix productId implementation (was not working)
- Ensure that we are not changing anything that is not mandatory (hostName, orgName, fullName)
This is an alternative proposal to #24283
This does not fix#19860 yet though.
For our use-case, we do not want to customize the network information (or any information in fact).
What is used in the template should remain intact.
* Added find_obj() function
* Fix the returned object-list (unused yet)
* Small improvement
* Support DHCP type and fix customizations

PR #5165 at https://github.com/ansible/ansible-modules-core/pull/5165
adds redirection and capture of stdout during execution of
docker-compose.
This doesn't necessarily catch all errors, since some are printed to
stderr and lost.
This extends the redirection to include stderr, and does minor string
processing to attempt to find a 'useful' message to present as the
final Ansible error.
