* [WIP] become plugins
Move from hardcoded method to plugins for ease of use, expansion and overrides
- load into connection as it is going to be the main consumer
- play_context will also use to keep backwards compat API
- ensure shell is used to construct commands when needed
- migrate settings remove from base config in favor of plugin specific configs
- cleanup ansible-doc
- add become plugin docs
- remove deprecated sudo/su code and keywords
- adjust become options for cli
- set plugin options from context
- ensure config defs are avaialbe before instance
- refactored getting the shell plugin, fixed tests
- changed into regex as they were string matching, which does not work with random string generation
- explicitly set flags for play context tests
- moved plugin loading up front
- now loads for basedir also
- allow pyc/o for non m modules
- fixes to tests and some plugins
- migrate to play objects fro play_context
- simiplify gathering
- added utf8 headers
- moved option setting
- add fail msg to dzdo
- use tuple for multiple options on fail/missing
- fix relative plugin paths
- shift from play context to play
- all tasks already inherit this from play directly
- remove obsolete 'set play'
- correct environment handling
- add wrap_exe option to pfexec
- fix runas to noop
- fixed setting play context
- added password configs
- removed required false

* cleanup
remove callers to removed func
removed --sudo cli doc refs
remove runas become_exe
ensure keyerorr on plugin

backwards compat for plugins using BECOME_METHODS
* Port become_plugins to context.CLIARGS
This is a work in progress:
* Stop passing options around everywhere as we can use context.CLIARGS
instead
* Refactor make_become_commands as asked for by alikins
* Typo in comment fix
* Stop loading values from the cli in more than one place
Both play and play_context were saving default values from the cli
arguments directly. This changes things so that the default values are
loaded into the play and then play_context takes them from there.
* Rename BECOME_PLUGIN_PATH to DEFAULT_BECOME_PLUGIN_PATH
As alikins said, all other plugin paths are named
DEFAULT_plugintype_PLUGIN_PATH. If we're going to rename these, that
should be done all at one time rather than piecemeal.
* One to throw away
This is a set of hacks to get setting FieldAttribute defaults to command
line args to work. It's not fully done yet.
After talking it over with sivel and jimi-c this should be done by
fixing FieldAttributeBase and _get_parent_attribute() calls to do the
right thing when there is a non-None default.
What we want to be able to do ideally is something like this:
class Base(FieldAttributeBase):
_check_mode = FieldAttribute([..] default=lambda: context.CLIARGS['check'])
class Play(Base):
# lambda so that we have a chance to parse the command line args
# before we get here. In the future we might be able to restructure
# this so that the cli parsing code runs before these classes are
# defined.
class Task(Base):
pass
And still have a playbook like this function:
---
- hosts:
tasks:
- command: whoami
check_mode: True
(The check_mode test that is added as a separate commit in this PR will
let you test variations on this case).
There's a few separate reasons that the code doesn't let us do this or
a non-ugly workaround for this as written right now. The fix that
jimi-c, sivel, and I talked about may let us do this or it may still
require a workaround (but less ugly) (having one class that has the
FieldAttributes with default values and one class that inherits from
that but just overrides the FieldAttributes which now have defaults)
* Revert "One to throw away"
This reverts commit 23aa883cbed11429ef1be2a2d0ed18f83a3b8064.
* Set FieldAttr defaults directly from CLIARGS

* Logic fix
* Nuke connection testing if it supports specific become methods
* Remove unused vars
* Address rebase issues
* Fix path encoding issue
* Remove unused import
* Various cleanups
* Restore network_cli check in _low_level_execute_command
* type improvements for cliargs_deferred_get and swap shallowcopy to default to False
* minor cleanups
* Allow the su plugin to work, since it doesn't define a prompt the same way

* Add helper to assist connection plugins in knowing they need to wait for a prompt
* Fix tests and code expectations
* Doc updates
* Various additional minor cleanups

* Note: Python2 is not as intelligent at detecting false import loops as
Python3. context_objects.py cannot be added to cli/arguments because it
would set up an import loop between cli/__init__.py,
cli/arguments/context_objects.py, and context.py on Python2.

* Mark methods which are really functions as staticmethod
* Fix calls to other staticmethods to use the subclass rather than the
base class so that any inheritance overriding will be honored.
* Remove unnecessary logic and dead code
* Fix a typo in a docstring of how to implement subclass init_parser()
methods
* Call superclass's post_process_args in ansible-doc
* Fix copyright comment according to suggested practice
The goal of breaking apart the base_parser() function is to get rid of
a bunch of conditionals and parameters in the code and, instead, make
code look like simple composition.
When splitting, a choice had to be made as to whether this would operate
by side effect (modifying a passed in parser) or side effect-free
(returning a new parser everytime).
Making a version that's side-effect-free appears to be fighting with the
optparse API (it wants to work by creating a parser object, configuring
the object, and then parsing the arguments with it) so instead, make it
clear that our helper functions are modifying the passed in parser by
(1) not returning the parser and (2) changing the function names to be
more clear that it is operating by side-effect.
Also move all of the generic optparse code, along with the argument
context classes, into a new subdirectory.
* Once cli args are parsed, they're constant. So, save the parsed args
into the global context for everyone else to use them from now on.
* Port cli scripts to use the CLIARGS in the context
* Refactor call to parse cli args into the run() method
* Fix unittests for changes to the internals of CLI arg parsing
* Port callback plugins to use context.CLIARGS
* Got rid of the private self._options attribute
* Use context.CLIARGS in the individual callback plugins instead.
* Also output positional arguments in default and unixy plugins
* Code has been simplified since we're now dealing with a dict rather
than Optparse.Value

* Retain vault password as bytes in 2.2
Prior to 2.2.1, the vault password was read in as byes and then remained
bytes all the way through the code. A bug existed where bytes and text
were mixed, leading to a traceback with non-ascii passwords. In devel,
this was fixed by changing the read in password to text type to match
with our overall strategy of converting at the borders. This was
backported to stable-2.2 for the 2.2.1 release.
On reflection, this should not have been backported as it causes
passwords which were originally non-utf-8 to become utf-8. People will
then have their working 2.2.x vault files become in-accessible.
this commit pipes bytes all the way through the system for vault
password. That way if a password is read in as a non-utf-8 character
sequence, it will continue to work in 2.2.2+. This change is only for
the 2.2 branch, not for 2.3 and beyond.
Why not everywhere? The reason is that non-utf-8 passwords will cause
problems when vault files are shared between systems or users. If the
password is read from the prompt and one user/machine has a latin1
encoded locale while a second one has utf-8, the non-ascii password
typed in won't match between machines. Deal with this by making sure
that when we encrypt the data, we always use valid utf-8.
Fixes#20398
(cherry picked from commit 5dcce0666a81917c68b76286685642fd72d84327)
if ANSIBLE_VAULT_PASSWORD_FILE is set, 'ansible-vault rekey myvault.yml'
will fail to prompt for the new vault password file, and will use
None.
Fix is to split out 'ask_vault_passwords' into 'ask_vault_passwords'
and 'ask_new_vault_passwords' to make the logic simpler. And then
make sure new_vault_pass is always set for 'rekey', and if not, then
call ask_new_vault_passwords() to set it.
ask_vault_passwords() would return values for vault_pass and new
vault_pass, and vault cli previously would not prompt for new_vault_pass
if there was a vault_pass set via a vault password file.
Fixes#18247
Implement tag and skip_tag handling in the CLI() class. Change tag and
skip_tag command line options to be accepted multiple times on the CLI
and add them together rather than overwrite.
* Make it configurable whether to merge or overwrite multiple --tags arguments
* Make the base CLI class an abstractbaseclass so we can implement
functionality in parse() but still make subclasses implement it.
* Deprecate the overwrite feature of --tags with a message that the
default will change in 2.4 and go away in 2.5.
* Add documentation for merge_multiple_cli_flags
* Fix galaxy search so its tags argument does not conflict with generic tags
* Unit tests and more integration tests for tags
* Can be configured in the ansible.cfg for tasks/handlers individually
* If an included filename contains no vars or loops, it will be expanded
in-place as if it were marked as static
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.
Without at least one worker process, things break:
