* prepare_ovs call gather facts
As we are no longer using run_ovs_integration_tests.yml we need to
explicitly gather facts so we can call the correct package manager.
* typo
Absolute path trailing slash handling in absolute directories
find_needle() isn't passing a trailing slash through verbatim. Since
copy uses that to determine if it should copy a directory or just the
files inside of it, we have to detect that and restore it after calling
find_needle()

** Add --vault-id to name/identify multiple vault passwords
Use --vault-id to indicate id and path/type
--vault-id=prompt # prompt for default vault id password
--vault-id=myorg@prompt # prompt for a vault_id named 'myorg'
--vault-id=a_password_file # load ./a_password_file for default id
--vault-id=myorg@a_password_file # load file for 'myorg' vault id
vault_id's are created implicitly for existing --vault-password-file
and --ask-vault-pass options.
Vault ids are just for UX purposes and bookkeeping. Only the vault
payload and the password bytestring is needed to decrypt a
vault blob.
Replace passing password around everywhere with
a VaultSecrets object.
If we specify a vault_id, mention that in password prompts
Specifying multiple -vault-password-files will
now try each until one works
** Rev vault format in a backwards compatible way
The 1.2 vault format adds the vault_id to the header line
of the vault text. This is backwards compatible with older
versions of ansible. Old versions will just ignore it and
treat it as the default (and only) vault id.
Note: only 2.4+ supports multiple vault passwords, so while
earlier ansible versions can read the vault-1.2 format, it
does not make them magically support multiple vault passwords.
use 1.1 format for 'default' vault_id
Vaulted items that need to include a vault_id will be
written in 1.2 format.
If we set a new DEFAULT_VAULT_IDENTITY, then the default will
use version 1.2
vault will only use a vault_id if one is specified. So if none
is specified and C.DEFAULT_VAULT_IDENTITY is 'default'
we use the old format.
** Changes/refactors needed to implement multiple vault passwords
raise exceptions on decrypt fail, check vault id early
split out parsing the vault plaintext envelope (with the
sha/original plaintext) to _split_plaintext_envelope()
some cli fixups for specifying multiple paths in
the unfrack_paths optparse callback
fix py3 dict.keys() 'dict_keys object is not indexable' error
pluralize cli.options.vault_password_file -> vault_password_files
pluralize cli.options.new_vault_password_file -> new_vault_password_files
pluralize cli.options.vault_id -> cli.options.vault_ids
** Add a config option (vault_id_match) to force vault id matching.
With 'vault_id_match=True' and an ansible
vault that provides a vault_id, then decryption will require
that a matching vault_id is required. (via
--vault-id=my_vault_id@password_file, for ex).
In other words, if the config option is true, then only
the vault secrets with matching vault ids are candidates for
decrypting a vault. If option is false (the default), then
all of the provided vault secrets will be selected.
If a user doesn't want all vault secrets to be tried to
decrypt any vault content, they can enable this option.
Note: The vault id used for the match is not encrypted or
cryptographically signed. It is just a label/id/nickname used
for referencing a specific vault secret.

Crypto namespace contains the openssl modules. It has no integration
testing as of now.
This commits aims to add integration tests for the crypto namespace.
This will make it easier to spot breaking changes in the future.
This tests currently apply to:
* openssl_privatekey
* openssl_publickey
* openssl_csr
* vmware_host: Small fixes and docs updates
This PR includes:
- A fix to no longer require a datacenter folder for adding a host
- Documentation improvements
- Ensure imports are specific
* Update vmware_host
Fix adds following:

* Update example documentation
* Added test case for vmware_host

Sometimes MacOSX's pwd doesn't return an expanded path. Not sure why
but this test is still valid if we expand it via a playbook filter so
go ahead and do that.
* We need a directory walker that can handle symlinks, empty directories,
and some other odd needs. This commit contains a directory walker that
can do all that. The walker returns information about the files in the
directories that we can then use to implement different strategies for
copying the files to the remote machines.
* Add local_follow parameter to copy that follows local symlinks (follow
is for remote symlinks)
* Refactor the copying of files out of run into its own method
* Add new integration tests for copy

* Ensure that include_role properly fires handlers
include_role needs to ensure that any handlers included
with the role are added to the _notified_handler and
_listening_handler lists of the TaskQueueManager, otherwise
it fails when trying to run the handler.
Additionally, the handler needs to be added to the
PlayIterator's `_uuid_cache` or it fails after running
the handler
Add more uuid debug statements - this code was hard
to debug with existing debug statements, so add more
uuid information at little additional output cost.
Fixes#18411
* Add tests for include_role handlers
Tests for #18411
* Only use `git verify-tag` when verifying annotated tags
The command `git verify-tag` only applies to annotated tags. When
verifying lightweight tags, which are more similar to non-moving
branches, one has to use `git verify-commit` instead.
Using ':' as a separator is appropriate since that is one of the
characters not allowed in a Git reference name.

* Improve testing of the Git module's gpg verification
* Add default description string to vyos_interface
* If `state=up` it should remove the `disable` configuration
for interface. However, if no other interface parameter is configured
this ends up deleting the interface itself which is not the desired
behaviour. Hence adding a default description field to avoid such
scenario's.
* Minor changes
* Add default description to aggregate
The 'admin' word was being masked by Ansible as potential cred.
Let's just use network-operator since we are just testing here
we can create users in aggregate.
* Use Boto3 for ec2_group
Currently boto doesn't support ipv6. To support ipv6 in ec2_group, we need boto3.
boto3 has significant API changes, which caused more re-factoring for ec2_group module.
Added additional integration test to test_ec2_group role.
* Follow the standard for boto3 ansible
Fixed imports. Use boto3 ansible exception with camel_dict_to_snake_dict.
Refactored the call to authorize/revoke ingress and egress.
* Removed dependancy with module ipaddress

* Attempt yaml formatting of documentation string
* Add integration tests for postgres_db:dump/restore
* Update dump/restore logic to support new kw-args
Also attempt to support password; integration tests are
still failing.
* Revert to postgres user for dump/restore
Passing PGPASSWORD is not working for subprocesses. For the
moment, reverting to the strategy of failing if login_password
is set and using `postgres` for all testing of dump/restore.
* Various cleanups to have tests passing
* Working tests for {sql,tar} x {,bz2,gz,xz}
* Use pg_user to support FreeBSD
* Revert login_ prefixes and re-enable password support
All `login_` keywords are mapped to their non-prefix versions
so the previous changes were effectively using `postgres` for
all actions. With the proper keywords, PGPASSWORD-passing to
the subprocess is now working.
* Optionally add password
environ_update doesn't handle None values in the
dictionary to be added to the environment. Adding
check.
* Quick fixes
* Refactor login arguments after fixes from pchauncey
The fixes introduced by pchaunchy pointed to further issues
(like no --dbname on PG<=9.2) with the login parameters. This
refactors them and adds further tests.
Note: this will still not pass integration tests due to a further
issue with pg_dump as a non-admin user:
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 1925; 0 0 COMMENT EXTENSION plpgsql
pg_restore: [archiver (db)] could not execute query: ERROR: must be owner of extension plpgsql
* Introduce target_opts for passing limiting dumped/restored schemas
The current integration tests (PG version and template DBs) don't
permit a regular user (`{{ db_user1 }}`) access to plpgsql causing
restores to fail. By adding an option for passing arbitrary args to
pg_dump and pg_restore, testing is made easier. This also paves the
way for `-j` usage, once the PG version is bumped.

fixed test to new rc handling
* as a result of recent core engine changes to ignore rc, modules are responsible to set `failed` on nonzero RC if they want that behavior
* the `failed` filter currently triggers on nonzero RC, which caused the tests to false-pass
* updated tests to explicitly check both rc and failed keys, as well as using the failed filter.
Currently, when using this test, it fails with the following error
message:
> AttributeError: 'NoneType' object has no attribute 'rfind'
This is because there is no _raw_params value for parent_include.args

include_vars will now also return a key 'ansible_included_var_files'

This is useful information and, amongst other things, a way for users
to know exactly what files were included when debugging their

This also allows us to improve the integration tests around
include_vars.

Make pyca/cryptography the preferred backend for cryptographic needs (mainly vault) falling back to pycrypto
pyca/cryptography is already implicitly a dependency in many cases
through paramiko (2.0+) as well as the new openssl_publickey module,
which requires pyOpenSSL 16.0+. Additionally, pyca/cryptography is
an optional dep for better performance with vault already.
This commit leverages cryptography's padding, constant time comparisons,
and CBC/CTR modes to reduce the amount of code ansible needs to
maintain.
* Handle wrong password given for VaultAES format
* Do not display deprecation warning for cryptography on python-2.6
* Namespace all of the pycrypto imports and always import them
Makes unittests better and the code less likely to get stupid mistakes
(like using HMAC from cryptogrpahy when the one from pycrypto is needed)
* Add back in atfork since we need pycrypto to reinitialize its RNG just in case we're being used with old paramiko
* contrib/inventory/gce: Remove spurious require on pycrypto
(cherry picked from commit 9e16b9db275263b3ea8d1b124966fdebfc9ab271)
* Add cryptography to ec2_win_password module requirements
* Fix python3 bug which would pass text strings to a function which

* Attempt to add pycrypto version to setup deps
* Change hacking README for dual pycrypto/cryptography
* update dependencies for various CI scripts
* additional CI dockerfile/script updates
* add paramiko to the windows and sanity requirement set
This is needed because ansible lists it as a requirement. Previously
the missing dep wasn't enforced, but cryptography imports pkg_resources
so you can't ignore a requirement any more
* Add integration test cases for old vault and for wrong passwords
* helper script for manual testing of pycrypto/cryptography
* Skip the pycrypto tests so that users without it installed can still run the unittests
* Run unittests for vault with both cryptography and pycrypto backend
* Add new windows module win_psmodule
* Add checkmode, allow_clobber parameter, integration tests
* Add aliases, replace win_raw with win_shell
* restore original test_win_group1.yml, add powershel version test
* fix var type

* integration tests conditional tasks review
* documentation fix, test fix, adds result.change
* fix yml
* fix railing whitespace
* add nuget_changed and repository_changed in result
There are too many possible special cases for Ansible to be able to
precheck known_hosts files without introducing all kinds of false
failures.
* Alternative known_hosts paths
* Alternative host name aliases
* ssh host certificates
* SSHFP + DNSSEC
