* Make ansible_selinux facts a consistent type
Rather than returning a bool if the Python library is missing, return a dict with one key containing a message explaining there is no way to tell the status of SELinux on the system becasue the Python library is not present.
* Fix unit test
The /etc/os-release based distro detection doesn't
seem to work for Ubuntu 10.04 (no /etc/os-release?).
So it was testing the next case which was /etc/lsb-release to
see if it is 'Mandriva'. Since the check for existence of
(/etc/lsb-release, Mandrive) was the first non-empty dist
file match, 'ansible_distribution' was being set to 'Mandriva'
expecting to be corrected by the data from the dist file content.
But since the dist file parsing for Mandriva didn't match for
Ubuntu 10.04 /etc/lsb-release _and_ there is no Debian specific
lsb-release check, 'ansible_distribution' stayed at 'Mandriva'
and the dist file checking loop keeps going and eventually off
the end of the list before finding a better match.
Adding a debian/ubuntu specific check for /etc/lsb-release after
the debian os-release sets the info correctly and stops further
checking of dist files.
Fixes#30693
* Fix fact failures cause by ordering of collectors
Some fact collectors need info collected by other facts.
(for ex, service_mgr needs to know 'ansible_system').
This info is passed to the Collector.collect method via
the 'collected_facts' info.
But, the order the fact collectors were running in is
not a set order, so collectors like service_mgr could
run before the PlatformFactCollect ('ansible_system', etc),
so the 'ansible_system' fact would not exist yet.
Depending on the collector and the deps, this can result
in incorrect behavior and wrong or missing facts.
To make the ordering of the collectors more consistent
and predictable, the code that builds that list is now
driven by the order of collectors in default_collectors.py,
and the rest of the code tries to preserve it.
* Flip the loops when building collector names
iterate over the ordered default_collectors list
selecting them for the final list in order instead
of driving it from the unordered collector_names set.
This lets the list returned by select_collector_classes
to stay in the same order as default_collectors.collectors
For collectors that have implicit deps on other fact collectors,
the default collectors can be ordered to include those early.
* default_collectors.py now uses a handful of sub lists of
collectors that can be ordered in default_collectors.collectors.
fixes#30753fixes#30623
* Fix 'distribution' fact for ArchLinux
Allow empty wasn't breaking out of the process_dist_files
loop, so a empty /etc/arch-release would continue searching
and eventually try /etc/os-release. The os-release parsing
works, but the distro name there is 'Arch Linux' which does
not match the 2.3 behavior of 'Archlinux'
Add a OS_RELEASE_ALIAS map for the cases where we need to get
the distro name from os-release but use an alias.
We can't include 'Archlinux' in SEARCH_STRING because a name match on its keys
but without a match on the content causes a fallback to using the first
whitespace seperated item from the file content as the name.
For os-release, that is in form 'NAME=Arch Linux'
With os-release returning the right name, this also supports the
case where there is no /etc/arch-release, but there is a /etc/os-release
Fixes#30600
* pep8 and comment cleanup
* Fix pkg_mgr fact on OpenBSD
Add a OpenBSDPkgMgrFactCollector that hardcodes pkg_mgr
to 'openbsd_pkg'. The ansible collector will choose the
OpenBSD collector if the system is OpenBSD and the 'Generic'
one otherwise.
This removes PkgMgrFactCollectors depenency on the
'system' fact being in collected_facts, which also
avoids ordering issues (if the pkg mgr fact is collected
before the system fact...)
Fixes#30623
* Added the ability to extend the exception list in CloudRetry

* adds new filter plugins for network use cases
* adds parse_cli filter
* adds parse_cli_textfsm filter
* adds Template class to network_common
* adds conditional function to network_common
* fix up PEP8 issues
previously gather_subset=['!all'] would still gather the
min set of facts, and there was no way to collect no facts.
The 'min' specifier in gather_subset is equilivent to
exclude the minimal_gather_subset facts as well.
gather_subset=['!all', '!min'] will collect no facts
This also lets explicitly added gather_subsets override excludes.
gather_subset=['pkg_mgr', '!all', '!min'] will collect only the pkg_mgr
fact.
* Add 2.0-2.3 facts api compat (ansible_facts(), get_all_facts())
These are intended to provide compatibilty for modules that
use 'ansible.module_utils.facts.ansible_facts' and
'ansible.module_utils.facts.get_all_facts' from 2.0-2.3 facts
API.
Fixes#25686
Some related changes/fixes needed to provide the compat api:
* rm ansible.constants import from module_utils.facts.compat
Just use a hard coded default for gather_subset/gather_timeout
instead of trying to load it from non existent config if the
module params dont include it.
* include 'external' collectors in compat ansible_facts()
* Add facter/ohai back to the valid collector classes
facter/ohai had gotten removed from the default_collectors
class used as the default list for all_collector_classes by
setup.py and compat.py
That made gather_subset['facter'] fail.
* Add aggregate parameter validation
aggregate parameter validation will support checking each individual dict
to resolve conditions for aliases, no_log, mutually_exclusive,
required, type check, values, required_together, required_one_of
and required_if conditions in argspec. It will also set default values.
eg:
tasks:
- name: Configure interface attribute with aggregate
net_interface:
aggregate:
- {name: ge-0/0/1, description: test-interface-1, duplex: full, state: present}
- {name: ge-0/0/2, description: test-interface-2, active: False}
register: response
purge: Yes
Usage:
```
from ansible.module_utils.network_common import AggregateCollection
transform = AggregateCollection(module)
param = transform(module.params.get('aggregate'))
```
Aggregate allows supports for `purge` parameter, it will instruct the module
to remove resources from remote device that hasn’t been explicitly
defined in aggregate. This is not supported by with_* iterators
Also, it improves performace as compared to with_* iterator for network device
that has seperate candidate and running datastore.
For with_* iteration the sequence of operartion is
load-config-1 (candidate db) -> commit (running db) -> load_config-2
(candidate db) -> commit (running db) ...
With aggregate the sequence of operation is
load-config-1 (candidate db) -> load-config-2 (candidate db) -> commit
(running db)
As commit is executed only once per task for aggregate it has
huge perfomance benefit for large configurations.
* Fix CI issues

it with an underscore.
Add tests for improved `_camel_to_snake` function.
Reduce use of `re.compile` as it makes no sense when the
compilation result is not reused.

- included the ACI team
* New prototype using ACIModule
This PR includes:
- A new ACIModule object with various useful methods
* Module argument_spec now accepts a callable for the type argument, which is passed through and called with the value when appropriate. On validation/conversion failure, the name of the callable (or its type as a fallback) is used in the error message.
* adds basic smoke tests for custom callable validator functionality
* Move tests to their own file

Consolidate the module_utils, constants, and config functions that
convert values into booleans into a single function in module_utils.
Port code to use the module_utils.validate.convert_bool.boolean function
isntead of mk_boolean.
It was in lib/ansible/modules/system/setup.py since it
was the only thing using it, but move it back to module_utils
and add a ansible_collector.get_ansible_collector() to build
a facts collector just like the one used by setup.py
mv test_setup.py -> test_ansible_collector.py

* Add more mount point statvfs info including sizes
Based on https://github.com/ansible/ansible/pull/12073
facts.utils.get_mount_size() now returns a dict of most
of the posix statvfs data, including block_size and inode
counts.
Update the facts.hardware classes that use get_mount_size() to
use the new info by mount_info.update(mount_statvfs_inof) to merge.
* add back unit tests for LinuxHardware mount/fs facts
* add test cases for facts.utils.get_mount_size
* Support NetBSD 7.1+ style ifconfig -a output
network facts on NetBSD after 7.1 cvs would fail
because of format changes in 'ifconfig -a' output.
update code to support new and old format.
add unit tests for both based on
examples from Bruce V Chiarelli.
* wrap use of interfaces.keys() in list() for py3 compat
* sort interface ids for stability
* Fix ansible_cmdline initrd fact for UEFI
UEFI cmdline paths use \ path sep which would
get munged by cmdline fact collection.
* Make CmdLineFactCollector easier to test
extract the parsing of the /proc/cmdline content to
_parse_proc_cmdline()

- mv Virtual fact classes to facts/virtual
- mv Hardware.get_sysctl to facts/sysctl.py:get_sysctl
- Also mv get_uname_version from facts/utils.py -> distribution.py
since distribution.py is the only thing using it.
- add collector.py with new BaseFactCollector
- add a subclass for AnsibleFactCollector
- hook up dict key munging FactNamespaces
- add some test cases for testing the names of facts
- mv timeout stuff to facts.timeout
- rm ansible_facts()/get_all_facts() etc
- Instead of calling facts.ansible_facts(), fact collection
api used by setup.py is now to create an AnsibleFactCollector()
and call it's collect method.
- replace Facts.get_user_facts with UserFactCollector
- add a 'systems' facts package, mv UserFactCollector there
- mv get_dns_facts to DnsFactCollector
- mv get_env_facts to EnvFactCollector
- include the timeout length in exception message
- modules and module_utils that use AnsibleFactCollector
can now theoretically set the 'valid_subsets'
May be useful for network facts module that currently have
to reimplement a good chunk of facts.py to get gather_subsets
to work.
- get_local_facts -> system/LocalFactCollector
- get_date_time -> system/date_time.py
- get_fips_facts -> system/fips.py
- get_caps_facts() -> system/caps.py
- get_apparmor_facts -> system/apparmor.py
- get_selinux_facts -> system/selinux.py
- get_lsb_facts -> system/lsb.py
- get_service_mgr_facts -> system/service_mgr.py
- Facts.is_systemd_managed -> system/service_mgr.py
- get_pkg_mgr_facts -> system/pkg_mgr.py
- Facts()._get_mount_size_facts() -> facts.utils.get_mount_size()
- add unit test for EnvFactCollector
- add a test case for minimal gather_subsets
- add test case for collect_ids
- Make gather_subset match existing behavior or '!all'
If 'gather_subset' is provided as '!all', the existing behavior
(in 2.2/2.3) is that means 'dont collect any facts except those
from the Facts() class'. So 'skip everything except
'apparmor', 'caps', 'date_time', 'env', 'fips', 'local', 'lsb',
'pkg_mgr', 'python', 'selinux', 'service_mgr', 'user', 'platform', etc.
The new facts setup was making '!all' mean no facts at all, since
it can add/exclude at a finer granularity. Since that makes more
sense for the ansible collector, and the set of minimal facts to
collect is really more up to setup.py to decide we do just that.
So if setup.py needs to always collect some gather_subset, even
on !all, setup.py needs to have the that subset added to the
list it passes as minimal_gather_subset.
This should fix some intg tests that assume '!all' means that
some facts are still collected (user info and env for example).
If we want to make setup.py collect a more minimal set, we can do that.
- force facts_dicts.keys() to a list so py3 works
- split fact collector tests to test_collectors.py
- convert Facter(Facts) -> other/facter.py:FacterFactCollector
- add FactCollector.collect_with_namespace()
regular .collect() will return a dict with the key names
using the base names ('ip_address', 'service_mgr' etc)
.collect_with_namespace() will return a dict where the key names
have been transformed with the collectors namespace, if there is
one. For most, this means a namespace that adds 'ansible_' to the
start of the key name.
For 'FacterFactCollector', the namespace transforms the key to
'facter_*'.
- add test cases for collect_with_namespace
- move all the concrete 'which facts does setup.py' stuff to setup.py
The caller of AnsibleFactCollector.from_gather_subset() needs to
pass in the list of collector classes now.
- update system/setup.py to import all of the fact classes and pass
in that list.
- split the Distribution fact class up a bit
extracted the 'distro release' file handling (ie, linux
boxes with /etc/release, /etc/os-release etc) into its
own class.
- extract get_cmdline_facts -> cmdline.py
- extract get_public_ssh_host_keys -> system/ssh_pub_keys.py
- extract get_platform_facts -> system/platform.py
platform.py may be a good candidate for further splitting.
- rm test for plain Facts() base class
- let the base class for Collector unit tests provide collected_facts
some Collectors and/or their migrated Facts() subsclasses need
to look at facts collected by other modules ('ansible_architecture'
the main one...).
Collector.collect() has the collected_facts arg for this, so add
a class variable to BaseFactsTest so we can specify it.
- mv Ohai to other/ohai.py and convert to Collector
- update hardware/*.py to return facts (no side effects)
- mv AnsibleFactCollector to setup.py
- extra collector class gathering to module method in
facts/__init__.py (collector_classes_from_gather_subset)
- add a CollectorMetaDataCollector collector used to provide
the 'gather_setup' fact
- add unit test module for 'setup' module
(test/units/modules/system/setup.py)
- Collector init now doesnt need a module, but collect does
An instance of a FactCollector() isnt tied to a AnsibleModule
instance, but the collect() method can be, so optionally pass
in module to FactCollector.collect() (everywhere)
- add a default_collectors for list of default collectors
import and use it from setup.py module
eventually, would like to replace this with a plugin loader
style class finder/loader
- unit tests for module_utils/facts/__init__.py
- add unit tests for ohai facts collector
- remove self.facts side effect on populate() in hardware/sunos.py
- convert OpenBSDHardware() to rm side effects on self.facts
- try to rm some self.facts side effects in Network()
plumb in collected_facts from populate() where it is needed.
stop passing collected_facts into Network() [via cached_facts=,
where it eventually becomes self.facts]
- nothing provides Fact() cached_facts arg now, rm it
Facts() should be internal only implementation so nothing
should be using it.
Of course, now someone will.
- add a Collector.name attr to build a map of name->_fact_ids
To properly exclude a gather_subset spec like '!hardware', we
need to know that 'hardware' also means 'devices', 'dmi', etc.
Before, '!hardware' would remove the 'hardware' collector name
but not 'devices'. Since both would end up in id_collector_map,
we would still end up with the HardwareCollector in the collector
list. End result being that '!hardware' wouldn't stop hardware
from being collected.
So we need to be able to build that map, so add the Collector.name
attribute that is the primary name (like 'hardware') and let
Collector._fact_ids be the other fact ids that a collector is
responsible for.
Construct the aliases_map of Collector.name -> set of _fact_ids
in fact/__init__.py get_collector_names, and use it when we are
populating the exclude set.
- refactor of distribution.py
make the big OS_FAMILY literal a little easier to read
Also keys can now be any string instead of python literals
99% sure the test for 'KDE Neon' was wrong
I don't see how/where it should or could get 'Neon' instead
of 'KDE Neon' as provided in os-release NAME=
Use 'distribution' string for key to OS_MAP
ie, we dont need to make it a valid python label anymore so dont.
move _has_dist_file to module as _file_exists
easier to mock without mucking with os.path
mv platform.system() calls to within get_distribution_facts() instead
of Distribution() init.
- remove _json compat module
The code in here was to support:
-a 'json' python module that was not the standard one included
with python since 2.6.
- potentially fallback to simplejson if 'json' was not available.
'json' is available for all supported python versions now so
no longer needed.
- mv get_collector_names -> facts.collector
- mv collector_classes_from_gather_subset -> facts.collector
- mv collector tests from test_facts -> test_collector
- Use six's reduce() in sunos/netbsd hardware facts
- rm extraneous get_uname_version in utils
only system/distribution.py uses it
- Remove Facts() subclass metaclass usage
- using fact_id and a platform id for matching collectors
gut most of Facts() subclasses
rm Facts() subclasses with weird metaclass
only add collectors that match the fact_ids and the platform_info
to the list of collectors used.
atm, a collectors platform_id will default to 'Generic', and
any platform matches 'Generic'
goal is to select collector classes including matching the
systems platform in collector.py, instead of relying on
metaclasses in hardware/*. To finish this, the various
Facts() subclasses will need to be replaced entirely with
Collector() subclasses.
use collector classmethod platform_match() to match the platform
This lets the particular class decide if it is compatible with
a given platform_info. platform_info is a dict like obj, so it could be
expanded in the future.
Add a default platform_match to BaseFactCollector that matches
platform_info['system'] == cls._platform
They were needed previously to trigger a module
load on all the collector classes when we import
facts/hardare so that the Hardware() and related
classes that used __new__ and find_all_subclasses()
would work.
Now that is done in collectors based on platform matching
at runtime we dont need to do it py module import/parse
time. So the non empty __init__.pys are no longer needed
and their is a more flexible mechanism for selection
platform specific stuff.
facts/facts.py is no longer used, rm'ed
- if we dont find an implement class for gather spec.. just ignore it.
Would be useful to add a warn to warn about this case.

- added new selinux fact to clarify python lib
the selinux fact is boolean false when the library is not installed,
a dictionary/hash otherwise, but this is ambigous
added new fact so we can eventually remove the type dichtomy and normalize it as a dict
Re-add of devel commit 85c7a7b844 to
the new code layout, since it got removed in merge/rebase
This is required for modules that may return a non-zero `rc` value for a
successful run, similar to #24865 for Windows fixing **win_chocolatey**.
We also disable the dependency on `rc` value only, even if `failed` was
set.
Adapted unit and integration tests to the new scheme.
Updated raw, shell, script, expect to take `rc` into account.

* updated documentation, remmoved parens
* fixed tabs
The timeout for gathering facts needs to be settable from three places
(highest precedence to lowest):
* programmatically
* ansible.cfg (equivalent to the user specifying it explicitly when
calling setup)
* from the default value
The code was changed in b4bd6c80de to
allow programmatically and the default value to work correctly but
setting via ansible.cfg/parameter was broken.
This change should fix setting via ansible.cfg and adds unittests for
all three cases
Fixes#23753
When building in automated build systems, there are sometimes cases
where the user doing the building does not have a .ssh directory. In
this case, we need to mock out some os.path functions so that the
add_host_key() function we're testing won't complain or try to create
one.
* Update module_utils.six to latest
We've been held back on the version of six we could use on the module
side to 1.4.x because of python-2.4 compatibility. Now that our minimum
is Python-2.6, we can update to the latest version of six in
module_utils and get rid of the second copy in lib/ansible/compat.
Add support for default credentials. Practically, this means that a playbook creator would not have to specify the service_account_email or credentials_file Ansible parameters.
Default Credentials only work when running on Google Cloud Platform. The 'project_id' is still required.
A test has been added to trigger this condition.
