A parameter of type int should accept int and string, but not float.
A parameter of type float should accept float, int, and string.
Also reset the arguments in another test so that it runs cleanly. This
agrees with what all the other tests are doing.
Includes:
* Tests to create, delete, resize, recreate and configure an Autoscaler
* Tests for parameters only. Use TEST_FLAGS="--tags 'param-check'" to execute only these tests.
Requires:
* An instance template to be configured in your project.
* Improve unit testing of 'password' lookup
The tests showed some UnicodeErrors for the
cases where the 'chars' param include unicode,
causing the 'getattr(string, c, c)' to fail.
So the candidate char generation code try/excepts
UnicodeErrors there now.
Some refactoring of the password.py module to make
it easier to test, and some new tests that cover more
of the password and salt generation.
* More refactoring and fixes.
* manual merge of text enc fixes from pr17475
* moving methods to module scope
* more refactoring
* A few more text encoding fixes/merges
* remove now unused code
* Add test cases and data for _gen_candidate_chars
* more test coverage for password lookup
* wip
* More text encoding fixes and test coverage
* cleanups
* reenable text_type assert
* Remove unneeded conditional in _random_password
* Add docstring for _gen_candidate_chars
* remove redundant to_text and list comphenesion
* Move set of 'chars' default in _random_password
on py2, C.DEFAULT_PASSWORD_CHARS is a regular str
type, so the assert here fails. Move setting the
default into the method and to_text(DEFAULT_PASSWORD_CHARS)
if it's needed.
* combine _random_password and _gen_password
* s/_create_password_file/_create_password_file_dir
* native strings for exception msgs
* move password to_text to _read_password_file
* move to_bytes(content) to _write_password_file
* add more test assertions about genned pw's
* Some cleanups to alikins and abadger's password lookup refactoring:
* Make DEFAULT_PASSWORD_CHARS into a text string in constants.py
- Move this into the nonconfigurable section of constants.
* Make utils.encrypt.do_encrypt() return a text string because all the
hashes in passlib should be returning ascii-only strings and they are
text strings in python3.
* Make the split up of functions more sane:
- Don't split such that conditionals have to occur in two separate functions.
- Don't go overboard: Good to split file system manipulation from parsing
but we don't need to do every file manipulation in a separate
function.
- Don't split so that creation of the password store happens in two
parts.
- Don't split in such a way that no decisions are made in run.
* Organize functions by when it gets called from run().
* Run all potential characters through the gen_candidate_chars function
because it does both normalization and validation.
* docstrings for functions
* Change when we store salt slightly. Store it whenever it was already
present in the file as well as when encrypt is requested. This will
head of potential idempotence bugs where a user has two playbook tasks
using the same password and in one they need it encrypted but in the
other they need it plaintext.
* Reorganize tests to follow the order of the functions so it's easier
to figure out if/where a function has been tested.
* Add tests for the functions that read and write the password file.
* Add tests of run() when the password has already been created.
* Test coverage currently at 100%
As suggested in feedback on
https://github.com/ansible/ansible/pull/17575, add
os_family to test_distribution_version. Add the
correct os_family to the existing testcase data
entries.
Also add os_family to the output of
gen_distribution_version_testcase.py so any new
generated entries will contain this data.
* Make is_encrypted_file handle both files opened in text and binary mode
On python3, by default files are opened in text mode. Since we know
the encoding of vault files (and especially the header which is the
first set of bytes) we can decide whether the file is an encrypted
vault file in either case.
* Fix is_encrypted_file not resetting the file position
* Update is_encrypted_file to check that all the data in the file is ascii
* For is_encrypted_file(), add start_pos and count parameters
This allows callers to specify reading vaulttext from the middle of
a file if necessary.
* Combine VaultLib.encrypt() and VaultLib.encrypt_bytestring()
* Change vault's is_encrypted() to take either text or byte strings and to return False if any part of the data is non-ascii.
* Remove unnecessary use of six.b
* Vault Cipher: mark a few methods as private.
* VaultAES256._is_equal throws a TypeError if given non byte strings
* Make VaultAES256 methods that don't need self staticmethods and classmethods
* Mark VaultAES and is_encrypted as deprecated
* Get rid of VaultFile (unused and feature implemented in a different way)
* Normalize variable and parameter names on plaintext, ciphertext, vaulttext
* Normalize variable and parameter names on "b_" prefix when dealing with bytes
* Test changes:
* Remove redundant tests( both checking the same byte string)
* Fix use of format string without format operator
* Enable vault editor tests on python3
* Initialize the vault_cipher for VaultAES256 testing in setUp()
* Make assertTrue and assertFalse take the actual method calls for
better error messages.
* Test that non-ascii byte strings compare correctly.
* Test that unicode strings and ints raise TypeError
* Test-specific:
* Removed test_methods_exist(). We only have one VaultLib so the
implementation is the assurance that the methods exist. (Can use an abc for
this if it changes).
* Add tests for both byte string and text string input where the API takes either.
* Convert "assert" to unittest assert functions or add a custom message where
that will make failures easier to debug.
* Move instantiating the VaultLib into setUp().
* Added aws_retry decorator function with unit tests
* Restructured the code to be used with a base class.
This base class CloudRetry can be reused by any other cloud provider.
This decorator should be used in situations, where you need to implement
a backoff algorithm and want to retry based on the status code from the
exception.
* updated documentation
* fixed tabs
* added botocore and boto3 to requirements.txt
* removed cloud.py from py24 tests, as it depends on boto3
* fix relative imports
* updated test to be 2.6 compat
* updated method name from retry to backoff
* readded lxd
* Updated default backoff from 2 seconds to 1.1s.
This will be about a total of 48 seconds in 10 tries. This is
configurable.
* Fixes to the controller text model
* Change command line args to text type
* Make display replace undecodable bytes with replacement chars. This
is only a problem on pyhton3 where surrogates can enter into the msg
but sys.stdout doesn't know how to handle them.
* Remove a deprecated playbook syntax in unicode.yml
* Fix up run_cmd to change its parameters to byte string at appropriate times.
* Enable more integration tests for python 3.
* Split out python 3 integration tests.
Now that we're running more integration tests on python 3, the
tests are taking long enough that they warrant splitting out in
the same way the python 2 tests are split.
We couldn't copy to_unicode, to_bytes, to_str into module_utils because
of licensing. So once created it we had two sets of functions that did
the same things but had different implementations. To remedy that, this
change removes the ansible.utils.unicode versions of those functions.
The test_async test target was updated to accommodate changes in
output buffering behavior in python 3. This change in behavior
may need to be addressed in the future.
* Fix paramiko's exec_command() to return bytes on python3
* Run test_connection for python3 now too
* Fix atomic_move for problem in shippable's testing
* Python-2.4 needs to use b()
for `VariableManager._get_magic_variables()`.
This saves a lot of time re-iterating the nearly always constant global
list of groups and their members.
Generate once and cache, and invalidate cache in case `add_host:` or
`group_by:` are used.
* Port set_*_if_different functions to python3
* Add surrogate_or_strict and surrogate_or_replace error handlers for
to_text, to_bytes, to_native
* Set default error handler to surrogate_or_replace
* Make use of the new error handlers in the already ported code
* Move the unittests for module_utils._text as they aren't in basic.py
* Cleanup around SEQUENCETYPE. On python2.6+ SEQUENCETYPE includes
strings so make sure code omits those explicitly if necessary
* Allow arg_spec aliases to be other sequence types
* New features for include_vars
include_vars.py now allows you to include an entire directory and its nested directories of variable files.
Added Features..
* Ignore by default *.md, *.py, and *.pyc
* Ignore any list of files.
* Only include files nested by depth (default=unlimited)
* Match only files matching (valid regex)
* Sort files alphabetically and load in that order.
* Sort directories alphabetically and load in that order.
```
- include_vars: 'vars/all.yml'
- name: include all.yml
include_vars:
file: 'vars/all.yml'
- name: include all yml files in vars/all and all nested directories
include_vars:
dir: 'vars/all'
- name: include all yml files in vars/all and all nested directories and save the output in test.
include_vars:
dir: 'vars/all'
name: test
- name: include all yml files in vars/services
include_vars:

- name: include only bastion.yml files
include_vars:
dir: 'vars'
files_matching: 'bastion.yml'
- name: include only all yml files exception bastion.yml
include_vars:

ignore_files: 'bastion.yml'
```
* Added whitelist for file extensisions (yaml, yml, json)
* Removed unit tests in favor of integration tests
While trying to fix the test suite on python3, I noticed
this test fail due to to_json adding more whitespace in
python3 than in python2. So -w should ignored those
differences.
* Fix to_native call in selinux_context and selinux_default_context to
use the error handler correctly.
* Port set_mode_if_different to work on python3
* Port atomic_move to work on python3
* Fix check_password_prompt variable which wasn't renamed properly
tempfile.NamedTemporaryFile keeps a file handle causing os.rename() to fail with windows based vboxfs: [Errno 26] Text file busy.
Changed NamedTemporaryFile to mkstemp() and added a finally block to unlink the temp file in each and every case.
* run_command needed a bit of tweaking to its string handling of
arguments.
* The run_command change fixes the last bit of lineinfile so we can
enable its tests
- Fix octal formatting of file mode in module response on py3.
- Convert file path to unicode in copy action.
- Enable file and copy module tests for py3 now that they pass.
Make some python3 fixes to make the unittests pass:
* galaxy imports
* dictionary iteration in role requirements
* swap_stdout helper for unittests
* Normalize to text string in a facts.py function
Fixes for these are either rewriting to get rid of the need for the
functions or using six.moves to get equivalent functions for both
python2 and python3
Make !vault-encrypted create a AnsibleVaultUnicode
yaml object that can be used as a regular string object.
This allows a playbook to include a encrypted vault
blob for the value of a yaml variable. A 'secret_password'
variable can have it's value encrypted instead of having
to vault encrypt an entire vars file.
Add __ENCRYPTED__ to the vault yaml types so
template.Template can treat it similar
to __UNSAFE__ flags.
vault.VaultLib api changes:
- Split VaultLib.encrypt to encrypt and encrypt_bytestring
- VaultLib.encrypt() previously accepted the plaintext data
as either a byte string or a unicode string.
Doing the right thing based on the input type would fail
on py3 if given a arg of type 'bytes'. To simplify the
API, vaultlib.encrypt() now assumes input plaintext is a
py2 unicode or py3 str. It will encode to utf-8 then call
the new encrypt_bytestring(). The new methods are less
ambiguous.
- moved VaultLib.is_encrypted logic to vault module scope
and split to is_encrypted() and is_encrypted_file().
Add a test/unit/mock/yaml_helper.py
It has some helpers for testing parsing/yaml
Integration tests added as roles test_vault and test_vault_embedded
* Give native strings to selinux library functions.
SELinux takes pathnames as native strings. That means we need to
convert to bytes on python2 and convert to text on python3.
Fixes#17155
* Read kitchen documentation, make module_utils params more like kitchen API
* Remove none nonstring strategy and add strict
* Raise TypeError on invalid nonstring strategy
* Document to_native()
* Make unittests for testing module_utils.text
* Rm py2.7+ code in docker connection plugin
The docker connection plugin was using subprocess.check_output
which only exists in python 2.7 and later. Connection plugins
need to support python2.6 so this replaces it with Popen/communicate()
* Handle docker ver errors in docker connection
Add unit tests for DockerConnection
Fixes#16971
test/units/plugins/action/test_action.py had code
for handling a bug in python 3.4's mock_open that
causes errors when reading binary data.
Moved to compat/tests/mock.py so other tests can
use it by default.
* actions/unarchive: fix unarchive from remote url
Currently unarchive from remote url does not work because the core
unarchive module was updated to support 'remote_src' [1], but the
unarchive action plugin was not updated for this. This causes failures
because the action plugin assumes it needs to copy a file to the
remote server, but in the case of downloading a file from a remote
url a local file does not exist, so an error occurs when the file is
not found.
[1] https://github.com/ansible/ansible-modules-core/commit/467516e
* test_unarchive: fix test with wrong remote_src use
The non-ascii filenames test had improperly set remote_src=yes even
though it was actually copying the file from the local machine (i.e.
the file did not already exist remotely). This test was passing
until the remote_src behavior of unarchive was fixed in 276550f.
Fixes#10779
Refactor some of the block device, mount point, and
mtab/fstab facts collection for linux for better
performance on systems with lots of block devices.
Instead of invoking 'lsblk' for every entry in mtab,
invoke it once, then map the results to mtab entries.
Change the args used for invoking 'findmnt' since the
previous combination of args conflicts, so this would
always fail on some systems depending on version.
Add test cases for facts Hardware()/Network()/Virtual() classes
__new__ method and verify they create the proper subclass based
on the platform.system() results.
Split out all the 'invoke some command and grab it's output'
bits related to linux mount paths into their own methods so
it is easier to mock them in unit tests.
Fix the DragonFly* classes that did not defined a 'platform'
class attribute. This caused FreeBSD systems to potentially
get the DragonFly* subclasses incorrectly. In practice it
didnt matter much since the DragonFly* subclasses duplicated
the FreeBSD ones. Actual DragonFly systems would end up with
the generic Hardware() etc instead of the DragonFly* classes.
Fix Hardware.__new__() on PY3, passing args to __new__
would cause "object() takes no parameters" errors. So
check for PY3 and just call __new__ without the args
See
https://hg.python.org/cpython/file/44ed0cd3dc6d/Objects/typeobject.c#l2818
for some explaination.
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.
* Query lookup plugin
* Add license and docstrings
* Add python3-ish imports
* Change query plugin type from lookup to filter
* Switch from dq to jsonpath_rw
* Add integration test for query filter
* Rename query filter to json_query
* Add jsonpath-rw
* Rename query filter to json_query
* Switch query implementation from jsonpath-rw to jmespath
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 feature changes the scalar value of `serial:` to a list, which

Binary module tests now download pre-compiled binaries from S3
instead of downloading go and compiling the modules.
Files downloaded form SourceForge are now downloaded from S3.
* Enabled more tests in test_service on systems with systemd.
* Fix inconsistency in cleaning up test service. The conditions for service setup and service cleanup were different.
* Add check mode run for service enable.
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.
Enable color output from integration tests in Docker containers:
* In run_tests.sh when output is attached to a terminal.
* In shippable/integration.sh using force mode (can be disabled).
Also fix blocks tests to work with or without color output
* switch cwd to basedir of task
This restores previous behaviour in pre 2.0 and allows for 'local type' plugins

Adds a new test for GalaxyCLI. Tests cases when:
- no actions are provided
- invalid actions are provided
- each valid action is provided
When parser() runs successfully the method returns True, creates a
SortedOptParser instance, a Galaxy instance, and updates certain class data.
A little unittest refactoring
* Add a class decorator to generate tests when using a unittest.TestCase base class
* Add a TestCase subclass with setUp() and tearDown() that sets up
module parameter parsing
* Move test_safe_eval to use the class decorator and ModuleTestCase base
class
* Move testing of set_mode_if_different into its own file and separate
some test methods out so we get better errors and more coverage in
case of errors.
* Naming convention for test cases doesn't need to duplicate information
that's already in the file path.
* Adding a test for GalaxyCLI and two methods on which it depends. Tests execute_info method.
* Adding a test for GalaxyCLI and two methods on which it depends. Tests execute_remove method.
* Update test_galaxy.py
* Revising test for GalaxyCLI execute_remove.
* Removing mocks
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.
* Lookup unencrypted password must not include salt
* Integration test lookup: remove previous directory

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.

* add git shallow fetch test
covers https://github.com/ansible/ansible-modules-core/issues/3782
updating a repo with depth=1 fails silently if version==HEAD
* disable git shallow tests for old git versions
Older git versions don't treat the --depth option correctly.
While the git module tried to work around this and introduced subtle
bugs, ansible/ansible-modules-core#3794 falls back to full checkouts.
Don't run the tests then.
This allows the PlaybookExecutor to receive more information regarding
what happened internal to the TaskQueueManager and strategy, to determine
things like whether or not the play iteration should stop.

The output of 'ansible-galaxy info' was formatting the
'galaxy_info' key with one char per line.
Previously, when building the output string, items in
role_info that had a dict for value, the label for

the text list in addition to being appended. Only
the append is needed.
Also added a unit test in test/units/cli/test_galaxy.py,

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.
* Comments cleanup
* Remember to output write the module line itself in powershell modules
* for line in lines strips the newlines so we have to add them back in
