Instead of immediately returning a failed code (indicating a break in
the play execution), we internally 'or' that failure code with the result
(now an integer flag instead of a boolean) so that we can properly handle
the rescue/always portions of blocks and still remember that the break
condition was hit.
Fixes#16937
Rather than repeatedly searching for tasks by uuid via iterating over
all known blocks, cache the tasks when they are added to the PlayIterator
so the lookup becomes a simple key check in a dict.

Run setfacl/chown/chmod on each temp dir and file.
This fixes temp file permissions handling on platforms such as FreeBSD
which always return success when using find -exec. This is done by
eliminating the use of find when setting up temp files and directories.
Additionally, tests that now pass on FreeBSD have been enabled for CI.
When a task result has an empty results list, the
list should be ignored when determining the results
of `_check_key`. Here the empty list is treated the
same as a non-existent list.
This fixes a bug that manifests itself with squashed
items - namely the task result contains the correct
value for the key, but an empty results list. The
empty results list was treated as zero failures
when deciding which handler to call - so the task
show as a success in the output, but is deemed to
have failed when deciding whether to continue.
This also demonstrates a mismatch between task
result processing and play iteration.
A test is also added for this case, but it would not
have caught the bug - because the bug is really in
the display, and not the success/failure of the
task (visually the test is more accurate).

This is a refactoring of the existing GCE utility module to support other projects on Google Cloud Platform.
The previous gce.py module was hard-coded specifically for GCE, and attempting to use it with other projects in GCP failed.
See https://github.com/ansible/ansible/pull/15918#issuecomment-220165913 for more detail.
This has also been an issue for others in the past, although they've handled it by simply
duplicating some of the logic of gce.py in their own modules.
- The existing gce.py module was renamed to gcp.py, and modified to remove any
imports or other code that refers to libcloud.compute or GCE (the GCE_* params were
retained for compatibility). I also renamed the gce_connect function to gcp_connect,
and modified the function signature to make supplying a provider, driver, and agent
information mandatory.
- A new gce.py module was created to handle connectivity to GCE. It imports the
appropriate libcloud.compute providers and drivers, and then passes them on
to gcp_connect in gcp.py. The constants and function signatures are the same
as the old gce.py, so compatibility with existing modules is retained.
- A new gcdns.py module was created to support PR ansible/ansible-modules-extras#2252
for two new Google Cloud DNS modules, and to demonstrate support for a non-GCE
Google Cloud service. It follows the same basic structure as the new gce.py module,
but imports from libcloud.dns instead.

I suspect this problem was masked previously as older versions of pywinrm
where significantly slower, allowing more time for the windows installer service to complete.
6eefc11c converted task.loop_control into an object, but while the other
callers were updated to use .loop_var instead of .get('loop_var'), this
site was overlooked.
This can be reproduced by including with loop_control a file that does
set_fact; a simple regression test along these lines is included.

Closes#16189
- Do not update base image packages unnecessarily.
- Fix incorrect package names.
- Remove commented out RUN statements.
- Sort list of packages to install.
Due to the fact that roles may be instantiated with different sets of
params (multiple inclusions of the same role or via role dependencies),
simply tracking notified handlers by name does not work. This patch
changes the way we track handler notifications by using the handler
object itself instead of just the name, allowing for multiple internal
instances. Normally this would be bad, but we also modify the way we
search for handlers by first looking at the notifying tasks dependency
chain (ensuring that roles find their own handlers first) and then at
the main list of handlers, using the first match it finds.
This patch also modifies the way we setup the internal list of handlers,
which should allow us to correctly identify if a notified handler exists
more easily.

Don't run the tests then.
This allows the PlaybookExecutor to receive more information regarding

Ansible when there was a percentage that was calculated to be less than
1.0 would run all hosts as the value for a rolling update.
The error is due to the fact that Python will round a
float that is under 1.0 to 0, which will trigger the case of
0 hosts. The 0 host case tells ansible to run all hosts.
The fix will see if the percentage calculation after int
conversion is 0 and will else to 1 host.
This makes our recursive, ast.parse performance measures as fast as
pre-ziploader baseline.
Since this unittest isn't testing that the returned module data is
correct we don't need to worry about os.rename not having any module
data. Should devise a separate test for the module and caching code
* Ziploader proof of concept (jimi-c)
* Cleanups to proof of concept ziploader branch:
* python3 compatible base64 encoding
* zipfile compression (still need to enable toggling this off for
systems without zlib support in python)
* Allow non-wildcard imports (still need to make this recusrsive so that
we can have module_utils code that imports other module_utils code.)
* Better tracebacks: module filename is kept and module_utils directory
is kept so that tracebacks show the real filenames that the errors
appear in.
* Make sure we import modules that are used into the module_utils files that they are used in.
* Set ansible version in a more pythonic way for ziploader than we were doing in module replacer
* Make it possible to set the module compression as an inventory var
This may be necessary on systems where python has been compiled without
zlib compression.
* Refactoring of module_common code:
* module replacer only replaces values that make sense for that type of
file (example: don't attempt to replace python imports if we're in
a powershell module).
* Implement configurable shebang support for ziploader wrapper
* Implement client-side constants (for SELINUX_SPECIAL_FS and SYSLOG)
via environment variable.
* Remove strip_comments param as we're never going to use it (ruins line
numbering)
* Don't repeat ourselves about detecting REPLACER
* Add an easy way to debug
* Port test-module to the ziploader-aware modify_module()
* strip comments and blank lines from the wrapper so we send less over the wire.

hit rescue/always portions of parent blocks
* Cleaned up logic in PlayIterator

beyond that point, so certain parts of the block integration test
were disabled.

The dep chain for roles created during the compile step had bugs, in
which the dep chain was overwriten and the original tasks in the role

some cases roles were not correctly getting variables from parents.

this was taken out in an effort to default to the user's shell but creates issues as this is not known ahead of time

fixes#13608
For the deps setup of integration tests, as we sometimes see odd
errors we can't reproduce, which may be related to slightly out of
date package dependencies.
At its most basic, this is nothing more than an array or hash lookup,
but when used in conjunction with map, it is very useful. For example,
while constructing an "ssh-keyscan …" command to update known_hosts on
all hosts in a group, one can get a list of IP addresses with:
groups['x']|map('extract', hostvars, 'ec2_ip_address')|list
This returns hostvars[a].ec2_ip_address, hostvars[b].ec2_ip_address, and
so on. You can even specify an array of keys for a recursive lookup, and
mix string and integer keys depending on what you're looking up:
['localhost']|map('extract', hostvars, ['vars','group_names',0])|first
== hostvars['localhost']['vars']['group_names'][0]
== 'ungrouped'
Includes documentation and tests.
Modeled after the yum tests but also tests local package installations
as fixed with PR#1256.
This depends on PRs #1256, #1261 and #1262 in ansible-modules-extra.
Looks like there are two pattern caches that need to be cleared for this to work- added the second one.
Added integration tests for add_host to prevent future regressions.
Check for database presence in a nice way, rather than
dropping the database.
Thankfully there was a syntax error in the previous

There was no check for whether it succeeded or not.

this enables forcing user when set to the same user as current user and ignoring .ssh/config
while keeping .ssh/config with current user if nothing is specified.

Fixes#12499
There doesn't appear to be anything that actually uses tmp_path in the
connection plugins so we don't need to pass that in to exec_command.
That change also means that we don't need to pass tmp_path around in
many places in the action plugins any more. there may be more cleanup
that can be done there as well (the action plugin's public run() method
takes tmp as a keyword arg but that may not be necessary).
As a sideeffect of this patch, some potential problems with chmod and
the patch, assemble, copy, and template modules has been fixed (those
modules called _remote_chmod() with the wrong order for their
parameters. Removing the tmp parameter fixed them.)
On Python 2, shlex.split() raises if you pass it a unicode object with
non-ASCII characters in it. The Ansible codebase copes by explicitly
converting the string using to_bytes() before passing it to
shlex.split().
On Python 3, shlex.split() raises ('bytes' object has no attribute 'read')
if you pass a bytes object. Oops.
This commit introduces a new wrapper function, shlex_split, that
transparently performs the to_bytes/to_unicode conversions only on
Python 2.
Currently I've only converted one call site (the one that was causing a
unit test to fail on Python 3). If this approach is deemed suitable,
I'll convert them all.
There were no inventory-specific unit tests earlier, so we add a new
directory for them with some initial low-level tests of _split_pattern
with various valid and deprecated pattern strings.
* Add exception handling when running PowerShell modules to provide exception message and stack trace.

1. The test did "name: '{{hostnames}}.{{item}}'" inside a with_sequence
loop, which didn't do what was intended: it expanded hostnames into
an array, appended ".1", and set name to the resulting string. This
can be converted to a simple with_items loop.
2. Some of the entries in hostnames contained punctuation characters,
which I see no reason to support in inventory hostnames anyway.
3. Once the add_host failures are fixed, the playbook later fails when
the unicode hostnames are interpolated into debug output in ssh.py
due to an encoding error. This is only one of the many places that
may fail when using unicode inventory hostnames; we work around it
by providing an ansible_ssh_host setting.
Labels must start with an alphanumeric character, may contain
alphanumeric characters or hyphens, but must not end with a hyphen.
We enforce those rules, but allow underscores wherever hyphens are
accepted, and allow alphanumeric ranges anywhere.
We relax the definition of "alphanumeric" to include Unicode characters
even though such inventory hostnames cannot be used in practice unless
an ansible_ssh_host is set for each of them.
We still don't enforce length restrictions—the fact that we have to
accept ranges makes it more complex, and it doesn't seem especially
worthwhile.
This adds a parse_address(pattern) utility function that returns
(host,port), and uses it wherever where we accept IPv4 and IPv6
addresses and hostnames (or host patterns): the inventory parser
the the add_host action plugin.
It also introduces a more extensive set of unit tests that supersedes
the old add_host unit tests (which didn't actually test add_host, but
only the parsing function).
There was code to support set literals (on Python 2.7 and newer), but it
was buggy: SAFE_NODES.union() doesn't modify SAFE_NODES in place,
instead it returns a new set object that is then silently discarded.
I added a unit test and fixed the code. I also changed the version
check to use sys.version_tuple instead of a string comparison, for
consistency with the subsequent Python 3.4 version check that I added in
the previous commit.
The full error was

Experiments show that Python 2 MagicMock() > 0 is true, so I'm setting

anyway.)
Required some rewiring in inventory code to make sure we're using
the DataLoader class for some data file operations, which makes mocking
them much easier.
Also identified two corner cases not currently handled by the code, related
to inventory variable sources and which one "wins". Also noticed we weren't
properly merging variables from multiple group/host_var file locations
(inventory directory vs. playbook directory locations) so fixed as well.
Replace .iteritems() with six.iteritems() everywhere except in
module_utils (because there's no 'six' on the remote host). And except
in lib/ansible/galaxy/data/metadata_template.j2, because I'm not sure
six is available there.
ansible is passing unicode arond internally so we should test the same
data.
* Add a zero length test for _count_newlines and fix the zero newlines

`assert (condition, message)` gets parsed by Python as `assert

Discovered by compileall on Python 3.4, which emits a SyntaxWarning for
this common mistake.
Note that this test was broken in devel because it was really just
duplicating the AES256 test because setting v.cipher_name to 'AES'
no longer selected AES after it was de-write-whitelisted.
Now that we've removed the VaultAES encryption code, we embed static
output from an earlier version and test that we can decrypt it.

This change is similar to https://github.com/ansible/ansible/pull/10465
It extends the logic there to also support none types. Right now if you have
a '!!null' in yaml, and that var gets passed around, it will get converted to
a string.
eg. defaults/main.yml
```
ENABLE_AWESOME_FEATURE: !!null # Yaml Null
OTHER_CONFIG:
secret1: "so_secret"
secret2: "even_more_secret"
CONFIG:
hostname: "some_hostname"
features:
awesame_feature: "{{ ENABLE_AWESOME_FEATURE}}"
secrets: "{{ OTHER_CONFIG }}"
```
If you output `CONFIG` to json or yaml, the feature flag would get represented in the output
as a string instead of as a null, but secrets would get represented as a dictionary. This is
a mis-match in behaviour where some "types" are retained and others are not. This change
should fix the issue.
I also updated the template test to test for this and made the changes to v2.
Added a changelog entry specifically for the change from empty string to null as the default.
Made the null representation configurable.
It still defaults to the python NoneType but can be overriden to be an emptystring by updating
the DEFAULT_NULL_REPRESENTATION config.
