* [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
- remove from doc building till they are ready
future development:
- deal with 'enable' and 'runas' which are not 'command wrappers' but 'state flags' and currently hardcoded in diff subsystems
* cleanup
remove callers to removed func
removed --sudo cli doc refs
remove runas become_exe
ensure keyerorr on plugin
also fix backwards compat, missing method is attributeerror, not ansible error
get remote_user consistently
ignore missing system_tmpdirs on plugin load
correct config precedence
add deprecation
fix networking imports
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)

This reverts commit c649d0ea32.
The change results in deadlock in network_cli while it is
waiting to check the return value of recv_ready() which
was added in this commit to improve performance
* Fix prompt mismatch issue for ios
Fixes#40884#44463
* If the command prompt is matched check if data is
still pending to be read from buffer.
* This fix adds a new timer `buffer_read_timeout`
which will be trigerred after command prompt
is matched and data is attempted to be read from channel.
If not data is present of channel the timer will expire
and response we be returned to calling function.

1fe67f9 introduced retries to the ssh connection put file and fetch
file. Unfortunately, that change broke the smart transport because it
started raising exceptions instead of returning from _run(). This
breakage is documented in #23711.
An attempt to fix it was made at #23717 but the first attempt was
objected to as needing to touch too much code. The second attmept was
objected to as smart was forced to encapsulate retries (thus retrying
a sftp "rety" times before trying scp "retry" times and then finally
moving onto piped). This third attempt has retries encapsulate smart.
So each sub-transport is tried once and if all three fail, another retry
attempt is made which tries each of the three again.

* test/: PEP8 compliancy
- Make PEP8 compliant
* Python3 chokes on casting int to bytes (#24952)

* Fix review comments
* Add generic fix for error prompt in py3
* Fix CI issue
* Fix network_cli unit test failure
Fix for persistent connection plugin on Python3. Note that fixes are also needed to each terminal plugin. This PR only fixes the ios terminal (as proof that this approach is workable.) Future PRs can address the other terminal types.
* On Python3, pickle needs to work with byte strings, not text strings.
* Set the pickle protocol version to 0 because we're using a pty to feed data to the connection plugin. A pty can't have control characters. So we have to send ascii only. That means
only using protocol=0 for pickling the data.
* ansible-connection isn't being used with py3 in the bug but it needs
several changes to work with python3.
* In python3, closing the pty too early causes no data to be sent. So
leave stdin open until after we finish with the ansible-connection
process.
* Fix typo using traceback.format_exc()
* Cleanup unnecessary StringIO, BytesIO, and to_bytes calls
* Modify the network_cli and terminal plugins for py3 compat. Lots of mixing of text and byte strings that needs to be straightened out to be compatible with python3
* Documentation for the bytes<=>text strategy for terminal plugins
* Update unittests for more bytes-oriented internals
Fixes#24355
Ansible will now automatically retry a connection if SSH returns an error:
mux_client_hello_exchange: write packet: Broken pipe
This is probably a bug in SSH, but because it's safe to retry this
connection there is no need for Ansible to fail because of it.
* Update module_utils.six to latest
We've been held back on the version of six we could use on the module
side to 1.4.x because of python-2.4 compatibility. Now that our minimum
is Python-2.6, we can update to the latest version of six in
module_utils and get rid of the second copy in lib/ansible/compat.
* Move retry logic into _ssh_retry decorator, and apply to exec_command, put_file and fetch_file
* Update tests to reflect change
* Move _ssh_retry to _run, and update tests to reflect
* piped should use exec_command instead of removed _exec_command
* Rework tests to support selectors instead of select.select
* fixes error where eos would close the cli shell
* fixes network_cli connection plugin to check before calling open_shell()
* fixes json commands being sent over eapi
