Toshio Kuratomi 52449cc01a AnsiballZ improvements
Now that we don't need to worry about python-2.4 and 2.5, we can make
some improvements to the way AnsiballZ handles modules.

* Change AnsiballZ wrapper to use import to invoke the module
  We need the module to think of itself as a script because it could be
  coded as:

      main()

  or as:

      if __name__ == '__main__':
          main()

  Or even as:

      if __name__ == '__main__':
          random_function_name()

  A script will invoke all of those.  Prior to this change, we invoked
  a second Python interpreter on the module so that it really was
  a script.  However, this means that we have to run python twice (once
  for the AnsiballZ wrapper and once for the module).  This change makes
  the module think that it is a script (because __name__ in the module ==
  '__main__') but it's actually being invoked by us importing the module
  code.

  There's three ways we've come up to do this.
  * The most elegant is to use zipimporter and tell the import mechanism
    that the module being loaded is __main__:
    * 5959f11c9d/lib/ansible/executor/module_common.py (L175)
    * zipimporter is nice because we do not have to extract the module from
      the zip file and save it to the disk when we do that.  The import
      machinery does it all for us.
    * The drawback is that modules do not have a __file__ which points
      to a real file when they do this.  Modules could be using __file__
      to for a variety of reasons, most of those probably have
      replacements (the most common one is to find a writable directory
      for temporary files.  AnsibleModule.tmpdir should be used instead)
      We can monkeypatch __file__ in fom AnsibleModule initialization
      but that's kind of gross.  There's no way I can see to do this
      from the wrapper.

  * Next, there's imp.load_module():
    * https://github.com/abadger/ansible/blob/340edf7489/lib/ansible/executor/module_common.py#L151
    * imp has the nice property of allowing us to set __name__ to
      __main__ without changing the name of the file itself
    * We also don't have to do anything special to set __file__ for
      backwards compatibility (although the reason for that is the
      drawback):
    * Its drawback is that it requires the file to exist on disk so we
      have to explicitly extract it from the zipfile and save it to
      a temporary file

  * The last choice is to use exec to execute the module:
    * https://github.com/abadger/ansible/blob/f47a4ccc76/lib/ansible/executor/module_common.py#L175
    * The code we would have to maintain for this looks pretty clean.
      In the wrapper we create a ModuleType, set __file__ on it, read
      the module's contents in from the zip file and then exec it.
    * Drawbacks: We still have to explicitly extract the file's contents
      from the zip archive instead of letting python's import mechanism
      handle it.
    * Exec also has hidden performance issues and breaks certain
      assumptions that modules could be making about their own code:
      http://lucumr.pocoo.org/2011/2/1/exec-in-python/

  Our plan is to use imp.load_module() for now, deprecate the use of
  __file__ in modules, and switch to zipimport once the deprecation
  period for __file__ is over (without monkeypatching a fake __file__ in
  via AnsibleModule).

* Rename the name of the AnsiBallZ wrapped module
  This makes it obvious that the wrapped module isn't the module file that
  we distribute.  It's part of trying to mitigate the fact that the module
  is now named __main)).py in tracebacks.

* Shield all wrapper symbols inside of a function
  With the new import code, all symbols in the wrapper become visible in
  the module.  To mitigate the chance of collisions, move most symbols
  into a toplevel function.  The only symbols left in the global namespace
  are now _ANSIBALLZ_WRAPPER and _ansiballz_main.

Adam Miller 562ff66a98 Fix pkg_mgr_name fact finding for Fedora (#40922)
* Properly handle default package manager vs apt

For distros where apt might be installed but is not the default
package manager for the distro, properly identify the default distro
package manager during fact finding and re-use fact finding from
DistributionFactCollector and instead of reimplementing small
portions of it in PkgMgrFactCollector

Add unit test to always check the apt + Fedora combination to test
the new code.

   and use system dirs
 - fix issue with bad tempdir (not existing/not createable/not writeable)
   i.e nobody and ~/.ansible/tmp
 - added tests for blockfile case

This reverts commit 5c614a59a6.

* changes based on PR feedback and changelog fragment

* changes based on the review

* Fix tmpdir when makedirs failed so we just use the system tmp

* Let missing remote_tmp fail

If remote_tmp is missing then there's something more basic wrong in the
communication from the controller to the module-side.  It's better to
be alerted in this case than to silently ignore it.

jborean and I have independently checked what happens if the user sets
ansible_remote_tmp to empty string and !!null and both cases work fine.
(null is turned into a default value controller-side.  empty string
triggers the warning because it is probably not a directory that the
become user is able to use).

Markos Chandras 1737b7be3e facts: suse: Fix major version detection for SUSE (#41416)
When parsing the distribution files such as /etc/os-release, we extract
the full distribution version but not the major version. As such, the
ansible_distribution_major_version ends up being 'NA' whereas the
ansible_distribution_version contains the full version.

Before this patch we get this on openSUSE Leap 15

ansible -o localhost -m setup -a filter=ansible_distribution_major_version
localhost | SUCCESS => {"ansible_facts": {"ansible_distribution_major_version": "NA"}, "changed": false}

After this patch we get this

ansible -o localhost -m setup -a filter=ansible_distribution_major_version
localhost | SUCCESS => {"ansible_facts": {"ansible_distribution_major_version": "15"}, "changed": false}

This also fixes the Tumbleweed distribution test to report a proper
major version and also adds a test for openSUSE Leap 15.0 to avoid
potential future regressions.

Yanis Guenane 496d10f7a8 Remove support for SSLv2 in test suite when not defined. (#39183)
When running the test test/units/module_utils/urls/test_open_url.py
test_open_url_no_validate_certs, the test fails because of the SSLv2
check.

Test is run on a machine using openssl 1.1.0g. By reading the openssl
man page[1], one can see that support for SSLv2 has been removed.

> Support for SSLv2 and the corresponding SSLv2_method(),
> SSLv2_server_method() and SSLv2_client_method() functions where removed
> in OpenSSL 1.1.0.
>
> SSLv23_method(), SSLv23_server_method() and SSLv23_client_method() were
> deprecated and the preferred TLS_method(), TLS_server_method() and
> TLS_client_method() functions were introduced in OpenSSL 1.1.0.

Hence this commit remove the uses of this flag when it is not defined.

Fact collector ordering deps (#31362)
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 fact deps when 'filter=ansible_fact' is used. (#33441)

facts that pass the filter would ever be passed
to other fact collectors.

For 'filter=ansible_service_mgr', even though it requires
the platform and distribution facts and even collects them,
they would get filtered out and never passed to the other
collectors that need them (service_mgr for ex).

The search string used to look for Clear Linux
was changed in 45a9f96774 to

a substring match for 'Clear Linux' in /usr/lib/os-release
is enough to consider a match.

Since the details of the full name in os-release varies
('Clear Linux Software for Intel Architecture',
 'Clear Linux OS for Intel Architecture', etc) the
search string match was failing and would fall back to the
'first word in the release file' method resulting in
ansible_distribution='NAME="Clear'

was matched.

Porting tests to pytest (#33387)
* Porting tests to pytest

* Achievement Get: No longer need mock/generator.py
  * Now done via pytest's parametrization
  * Port safe_eval to pytest
  * Port text tests to pytest
  * Port test_set_mode_if_different to pytest

* Change conftest AnsibleModule fixtures to be more flexible
  * Move the AnsibleModules fixtures to module_utils/conftest.py for sharing
  * Testing the argspec code requires:
    * injecting both the argspec and the arguments.
    * Patching the arguments into sys.stdin at a different level

* More porting to obsolete mock/procenv.py
  * Port run_command to pytest
  * Port known_hosts tests to pytest
  * Port safe_eval to pytest
  * Port test_distribution_version.py to pytest
  * Port test_log to pytest
  * Port test__log_invocation to pytest
  * Remove unneeded import of procenv in test_postgresql

* Port test_pip to pytest style
  * As part of this, create a pytest ansiblemodule fixture in
    modules/conftest.py.  This is slightly different than the
    approach taken in module_utils because here we need to override the
    AnsibleModule that the modules will inherit from instead of one that
    we're instantiating ourselves.

* Fixup usage of parametrization in test_deprecate_warn

* Check that the pip module failed in our test
