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.
revised porting guide entry
Integrate code coverage collection into AnsiballZ.
ci_coverage
ci_complete
* aws_eks: New module for managing AWS EKS
aws_eks module is used for creating and removing EKS clusters.
Includes full test suite and updates to IAM policies to enable it.
* Clean up all security groups
* appease shippable
* Rename aws_eks module to aws_eks_cluster
The compute policy was exceeding maximum size and contained
policies that already exist in ecs-policy.
Look up suitable AMIs rather than hardcode
We don't want to maintain multiple image IDs for multiple regions
so use ec2_ami_facts to set a suitable image ID
Improve exception handling
* Fix test-module failing to validate args
The test-module pass a wrong argument _ansible_tmp cause the validation failed.
Change the argument _ansible_tmp to _ansible_tmpdir to fix this.
* Add a integration test for test-module.
Prior to this change, we don't have a test for test-module.
This change ensure the correctness of test-module script.
Remove VPC permissions from network-policy.json as they mostly duplicate
compute-policy.json permissions - separating the VPC and compute permissions
would likely lead to further confusion.
We only needed it for migrating cherrypicks between the unified repo and
the ansible-modules-* repos. Now that we aren't supporting 2.3, we no
longer need this script.
* New module: ec2_vpc_vpn_facts
* Add integration tests for ec2_vpc_vpn_facts and the IAM permissions
* Add retry to VPC removal
* Use unique name for VGW
* Always clean up after tests and add retries
* create module tmpdir based on remote_tmp
* Source remote_tmp from controller if possible
* Fixed sanity test and not use lambda
* Added expansion of env vars to the remote tmp
* Fixed sanity issues
* Added note around shell remote_tmp option
* Changed fallback tmp dir to ~/.ansible/tmp to make shell defaults
* Add helpful failure message if target_type=ip is not supported
Create test case for target_type=ip not supported
* Update elb_target_group module to latest standards
Use AnsibleAWSModule
Improve exception handling
Improve connection handling
Enable awsvpc network mode for ECS services and tasks and
their underlying task definitions
Improve test suite to thoroughly test the changes
Use runme.sh technique to run old and new versions of botocore to
ensure that the modules work with older botocore and older network modes
and fail gracefully if awsvpc network mode is used with older botocore
* Add aws_ses_identity_policy module for managing SES sending policies
* Add option to AnsibleAWSModule for applying a retry decorator to all calls.
* Add per-callsite opt in to retry behaviours in AnsibleAWSModule
* Update aws_ses_identity_policy module to opt in to retries at all callsites.
* Add test for aws_ses_identity_policy module with inline policy.
* Remove implicit retrys on boto resources since they're not working yet.
Cloudfront needs CreateOriginAccessIdentity
Add profile parameter to setup-iam.yml. Could arguably just use
AWS_PROFILE but given that other tasks are using profile, should
be consistent.
* module_common: set required parameter templar

The search string used to look for Clear Linux
was changed in 45a9f96774 to
be more specific, but was too specific. Now finding
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'
Also add a meta fact indicating which search string
was matched.
Test case info from:
https://github.com/ansible/ansible/issues/31501#issuecomment-340861535Fixes#31501
People expect to be able to upload files to s3 using standard
locations for files.
Providing an action plugin that effectively rewrites the `src`
key to the result of finding such a file is a great help.

Provide all necessary permissions for AMI tests
Allow tests to run in us-east-2
Ensure `always` section gets used
Update tests to ensure that cleanup works better, and add
deletion idempotency test
After running hacking/test-module to generate some output,
the JSON output can be fed into the return skeletion generator
to create an excellent starting point for RETURN docs
* Update RDS parameter group for boto3
* Update to boto3
* Update to latest ansible standards
* Remove choices list for valid engines (See #19221 for context)
* Allow tagging
* Return some useful information, and document that information
* Add tests for rds_param_group

* Add supported by Red Hat field to ansible-doc output
* Add test runner to PATH
* Add Python3 support
* Updating env-setup.fish to use more portable '-exec' rather than '-delete'
* Create gen_egg_info function
Move code into a function similar to env-setup.
Silence all output when run with -q
* Add tests for group in a VPC
* Improve ec2_group output and documentation
Update ec2_group to provide full security group information
Add RETURN documentation to match
* Fix ec2_group creation within a VPC
Ensure VPC ID gets passed when creating security group
* Add test for auto creating SG
* Fix ec2_group auto group creation
* Add backoff to describe_security_groups
Getting LimitExceeded from describe_security_groups is definitely
possible (source: me) so add backoff to increase likelihood of
success.
To ensure that all `describe_security_group` calls are backed off,
remove implicit ones that use `ec2.SecurityGroup`. From there,
the decision to remove the `ec2` boto3 resource and rely on the client
alone makes good sense.
* Tidy up auto created security group
Add resource_prefix to auto created security group and delete
it in the `always` section.
Use YAML argument form for all module parameters
* 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
Added new parameter called cidr_ipv6 for specifying
ipv6 addresses inline with how boto3 handles ipv6 addresses.
* Updated integration test
* Added ipv6 integration test for ec2_group
* Set purge_rules to false for integration test
* Fixed import statements
Added example for ipv6.
Removed defining HAS_BOTO3 variable and import HAS_BOTO3 from ec2.
Cleaned up import statements.
* Fixed exception handling
* Add IAM permissions for ec2_group tests
Missing AuthorizeSecurityGroupEgress necessary for latest tests
* Wrapped botocore import in try/except block
Import just botocore to be more similar to other modules
* Fix ansible-doc traceback when a plugin doesn't parse correctly
* Change extract_metadata ivocation to take either an ast or source
code. When given source code, it can find file offsets for the start
and end of dict. When given the ast, it is quicker as it doesn't have
to reparse the source. Requires changing the call to the function to
use a keyword arg.
* Fix reading of metadata to find the last occurrence of
ANSIBLE_METADATA instead of the first.
* Add some more unittests to get closer to complete coverage
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
requires byte strings.
* 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
* Start of ansible config project
moved configuration definitions to external yaml file vs hardcoded
* updated constants to be a data strcutures that are looped over and also return origin of setting
changed to manager/data scheme for base classes
new cli ansible-config to view/manage ansible configuration settings
* prints green for default/unchanged and yellow for those that have been overriden
* added list action to show all configurable settings and their associated ini and env var names
* allows specifying config file to see what result would look like
* TBD update, edit and view options
removed test for functions that have been removed
env_Vars are now list of dicts
allows for version_added and deprecation in future
added a couple of descriptions for future doc autogeneration
ensure test does not fail if delete_me exists
normalized 'path expansion'
added yaml config to setup packaging
removed unused imports
better encoding handling
updated as per feedback
* pep8
* aws integration tests - provide an IAM policy that can be used for running them
* move documentation of aws policies into main integration testing documentation + some updates there
* Update testing_integration.rst
Edits
Made ansible-doc more plugin agnostic
We can have docs in lookup, callback, connectionm strategy, etc
Use first docstring and make pepizis happy
generalized module_docs to plugin_docs
documented cartesian, ssh, default, jsonfile, etc as examples
changed lack of docs to warning when listing
made smarter about bad docstrings
better blacklisting
added handling of options/config/envs/etc
move blacklist to find_plugins, only need once

Raise the bar for module `DOCUMENTAION`
This validator update was used to find the issues in https://github.com/ansible/ansible/pull/22297/files
**Validation**
* Updated Validation and docs to enforce more (items fixed in https://github.com/ansible/ansible/pull/22297/files)
* Use `suboptions` to document complex options
* Validate module name
* Validate deprecated modules have correct ANSIBLE_METADATA
**Module Documentation Generation**
* Document `suboptions:` Example https://gist.github.com/gundalow/4bdc3669d696268328ccc18528cc6718
* Tidy up HTML generation (valid HTML, no empty lists, etc)
**Documentation**
* Clarify the steps for deprecating a module
* Use correct RST headings
* Document `suboptions:` (options)
* Document `contains:` (returns)
**Details**
The aim is to get this (and corresponding module updates) complete by the time `devel` becomes `2.4`, as this allows us to raise the bar for new modules
Example `suboptions` https://gist.github.com/gundalow/4bdc3669d696268328ccc18528cc6718
The aim is to get this PR integrated into `devel` *before* we branch `stable-2.3`, this will allows us to:
* Raise the bar for new modules in 2.4
* Ensure the generated module documentation for 2.3 and higher is improved, important as we will be doing versioned docs moving forward.
* Update test-module

* Use ansible_python_interpreter to run modules
Use ansible_python_interpreter to run modules if
`-I ansible_python_interpreter` is set.
Remove unused default from `-I` help text.
* Update test-module to pep8 standards
- Replace nose usage with pytest.
- Remove legacy Shippable integration.sh.
- Update Makefile to use pytest and ansible-test.
- Convert most yield unit tests to pytest parametrize.
- Remove shebangs from:
- ini files
- unit tests
- module_utils
- plugins
- module_docs_fragments
- non-executable Makefiles
- Change non-modules from '/usr/bin/python' to '/usr/bin/env python'.
- Change '/bin/env' to '/usr/bin/env'.
Also removed main functions from unit tests (since they no longer
have a shebang) and fixed a python 3 compatibility issue with
update_bundled.py so it does not need to specify a python 2 shebang.
A script was added to check for unexpected shebangs in files.
This script is run during CI on Shippable.
* Remove old egg-info files before creating new ones
Currently, setup.py generates egg files then they are deleted. This change
fixes this behavior and matches that in env-setup.
* Do not try to move ansible*egg-info to lib/
setup.py creates the ansible.egg-info in lib/ so this step is unnecessary. Matches env-setup behavior.
* Better test for number of arguments in argv
This prevents an erronous error message from being thrown since set -q returns an error code with the number of variables not defined, resulting in a non-zero exit if no arguments are passed.
Indent case statement within switch statement.
Currently, "ansible localhost -m setup" can fail silently during the
run of gen_distribution_version_testcase.py, resulting in incorrect
output. Use check_output() rather than communicate() and handle
the exception if we get a nonzero return value.
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.
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.
Previously it also built the MANPAGES target
requiring asciidoc and libxml, before starting
a 'make docs' in docsite.
Also change the #! line in
hacking/dump_playbook_attributes.py to not specify
python2... yet.
* add tests for centos6, rhel6 and rhel7
* gen_distribution_version_testcase with python2.6
* remove unused imports
* fix redhat/vmware/... parsing
* add centos7 test case
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
* Could only have one alias before. Subsequent aliases overrode the
previous ones. Now multiple aliases work.
* Fix BLACKLISTED_MODULES. Previously, modules were listed in the
generated documentation despite being blacklisted
* Deprecated modules form extras were showing the (E) tag and not the
(D) tag. Reversed that now (Probably not necessary to also show the
E tag).
* Sort the deprecated modules alphabetically in the Category docs as
well as the list of all modules
* Optimization: Previously rendered the modules to rst twice once in all
group and once in individual categories. Fixed to only render them
once.
* Add fireball to blacklist and remove async_status (as people need to
use that).
* 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
