# Features provided by this module:

Policy.d helper functions
=========================
The functions in this module are designed, as a set, to provide an easy-to-use
set of hooks for classic charms to add in /etc/<service-name>/policy.d/
directory override YAML files.
(For charms.openstack charms, a mixin class is provided for this
functionality).
In order to "hook" this functionality into a (classic) charm, two functions are
provided:
maybe_do_policyd_overrides(openstack_release,
service,
blacklist_paths=none,
blacklist_keys=none,
template_function=none,
restart_handler=none)
maybe_do_policyd_overrides_on_config_changed(openstack_release,
service,
blacklist_paths=None,
blacklist_keys=None,
template_function=None,
restart_handler=None
(See the docstrings for details on the parameters)
The functions should be called from the install and upgrade hooks in the charm.
The `maybe_do_policyd_overrides_on_config_changed` function is designed to be
called on the config-changed hook, in that it does an additional check to
ensure that an already overriden policy.d in an upgrade or install hooks isn't
repeated.
In order the *enable* this functionality, the charm's install, config_changed,
and upgrade_charm hooks need to be modified, and a new config option (see
below) needs to be added. The README for the charm should also be updated.
Examples from the keystone charm are:
@hooks.hook('install.real')
@harden()
def install():
...
# call the policy overrides handler which will install any policy overrides
maybe_do_policyd_overrides(os_release('keystone'), 'keystone')
@hooks.hook('config-changed')
@restart_on_change(restart_map(), restart_functions=restart_function_map())
@harden()
def config_changed():
...
# call the policy overrides handler which will install any policy overrides
maybe_do_policyd_overrides_on_config_changed(os_release('keystone'),
'keystone')
@hooks.hook('upgrade-charm')
@restart_on_change(restart_map(), stopstart=True)
@harden()
def upgrade_charm():
...
# call the policy overrides handler which will install any policy overrides
maybe_do_policyd_overrides(os_release('keystone'), 'keystone')
Status Line
===========
The workload status code in charm-helpers has been modified to detect if
policy.d override code has been incorporated into the charm by checking for the
new config variable (in the config.yaml). If it has been, then the workload
status line will automatically show "PO:" at the beginning of the workload
status for that unit/service if the config option is set. If the policy
override is broken, the "PO (broken):" will be shown. No changes to the charm
(apart from those already mentioned) are needed to enable this functionality.
(charms.openstack charms also get this functionality, but please see that
library for further details).
"""
# The config.yaml for the charm should contain the following for the config
# option:
"""
use-policyd-override:
type: boolean
default: False
description: |
If True then use the resource file named 'policyd-override' to install
override yaml files in the service's policy.d directory. The resource
file should be a zip file containing at least one yaml file with a .yaml
or .yml extension. If False then remove the overrides.

Policy Overrides
----------------
This service allows for policy overrides using the `policy.d` directory. This
is an **advanced** feature and the policies that the service supports should be
clearly and unambiguously understood before trying to override, or add to, the
default policies that the service uses.
The charm also has some policy defaults. They should also be understood before
being overridden. It is possible to break the system (for tenants and other
services) if policies are incorrectly applied to the service.
Policy overrides are YAML files that contain rules that will add to, or
override, existing policy rules in the service. The `policy.d` directory is
a place to put the YAML override files. This charm owns the
`/etc/keystone/policy.d` directory, and as such, any manual changes to it will
be overwritten on charm upgrades.
Policy overrides are provided to the charm using a resource file called
`policyd-override`. This is attached to the charm using (for example):
juju attach-resource <charm-name> policyd-override=<some-file>
The `<charm-name>` is the name that this charm is deployed as, with
`<some-file>` being the resource file containing the policy overrides.
The format of the resource file is a ZIP file (.zip extension) containing at
least one YAML file with an extension of `.yaml` or `.yml`. Note that any
directories in the ZIP file are ignored; all of the files are flattened into a
single directory. There must not be any duplicated filenames; this will cause
an error and nothing in the resource file will be applied.
(ed. next part is optional is the charm supports some form of
template/substitution on a read file)
If a (ed. "one or more of") [`.j2`, `.tmpl`, `.tpl`] file is found in the
resource file then the charm will perform a substitution with charm variables
taken from the config or relations. (ed. edit as appropriate to include the
variable).
To enable the policy overrides the config option `use-policyd-override` must be
set to `True`.
When `use-policyd-override` is `True` the status line of the charm will be
prefixed with `PO:` indicating that policies have been overridden. If the
installation of the policy override YAML files failed for any reason then the
status line will be prefixed with `PO (broken):`. The log file for the charm
will indicate the reason. No policy override files are installed if the `PO
(broken):` is shown. The status line indicates that the overrides are broken,
not that the policy for the service has failed - they will be the defaults for
the charm and service.
If the policy overrides did not install then *either* attach a new, corrected,
resource file *or* disable the policy overrides by setting
`use-policyd-override` to False.
Policy overrides on one service may affect the functionality of another
service. Therefore, it may be necessary to provide policy overrides for
multiple service charms to achieve a consistent set of policies across the
OpenStack system. The charms for the other services that may need overrides
should be checked to ensure that they support overrides before proceeding.

the service restart if the policy.d file is changed. This should normally
be None as oslo.policy automatically picks up changes in the policy.d

"""Provide a subset of the ``python-apt`` module API.
Data collection is done through subprocess calls to ``apt-cache`` and
``dpkg-query`` commands.
The main purpose for this module is to avoid dependency on the
``python-apt`` python module.
The indicated python module is a wrapper around the ``apt`` C++ library
which is tightly connected to the version of the distribution it was
shipped on. It is not developed in a backward/forward compatible manner.
This in turn makes it incredibly hard to distribute as a wheel for a piece
of python software that supports a span of distro releases [0][1].
Upstream feedback like [2] does not give confidence in this ever changing,
so with this we get rid of the dependency.
