Fact collector ordering deps ()
Add deps/requires for fact collectors

Fact collectors can now set a required_facts
class attribute that will be a set of the names
of fact collectors they require to be run first.

ie, if a collector needs to know the ansible_distribution,
it should set it's required_facts to include 'distribution'

        required_facts = set(['distribution'])

If a collector requires another collector, it gets added
to the selected collector names.

We then topological sort the ordering of the collectors
so that deps work out (ie, 'distribution' will run before
'service_mgr')

required_facts were added to the collectors for:

        - network (requires 'distribution', 'platform')
        - hardware (requires 'platform')
        - service_mgr (requires 'distribution', 'platform')

Fix name references for facts (need 'ansible_' prefix)
is service_mgr

95abc1d82e Fix fact failures cause by ordering of collectors ()
* 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.

27a015f0ad add a 'min' type for gather_subset to collect nothing ()
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.

17ab546c48 Add 2.0-2.3 facts api compat (ansible_facts(), get_all_facts()) ()
* 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 

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.

45a9f96774 Facts Refresh (2.4 roadmap) ()
Facts Refresh (2.4 roadmap)

This commit implements most of the 2.4 roadmap 'Facts Refresh'
- move facts.py to facts/__init__.py
- move facts Distribution() to its own class
- add a facts/utils.py
- move get_file_content and get_uname_version to facts/utils.py
- move Facts() class from facts/__init__ to facts/facts.py
- mv get_file_lines to facts/utils.py
- mv Ohai()/Facter() class to facts/ohai.py and facter.py
- Start moving fact Hardware() classes to facts/hardware/*.py
- mv HPUX() hardware class to facts/hardware/hpux.py
- move SunOSHardware() fact class to facts/hardware/sunos.py
- move OpenBSDHardware() class to facts/hardware/openbsd.py
- mv FreeBsdHardware() and DragonFlyHardware() to facts/hardware/
- mv NetBSDHardware() to facts/hardware/netbsd.py
- mv Darwin() hardware class to facts/hardware/darwin.py
- pep8/etc cleanups on facts/hardware/*.py
- Mv network facts classes to facts/network/*.py
- 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.

- Fix SD-UX typo (should be HP-UX)

- Port fix for  (0 sockets) to this branch

    This readds the change from 8ad182059d
    that got lost in merge/rebase

    Fixes 

- port sunos fact locale fix for  to this branch

    based on e558ec19cd

    Fixes 

    Solaris fact fix ()

    ensure locale for solaris fact gathering

    fixes issue with locale interfering with proper reading of decimals

- raise exceptions in the air like we just dont care.

    Pretty much ignore any not exit exception in facts
    collection. And add some test cases.

- 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
