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
* removes unneeded supports_multiplexing var
* refactors terminal_prompts_re to terminal_stdout_re
* refactors terminal_errors_re to terminal_stderr_re
* updates network_cli unit test cases
The python 'future' module provides a 'builtins' package
to emulate the py3 'builtins' modules. If installed, the
unit tests that reference builtins.__import__ fail because
the future 'builtins' is imported and it is missing __import__.
Use ansible.compat.six.moves.builtins instead of importing
'builtins' or __builtin__
Fixes#14996
- centralized skipping
- also fixed module name broken by previous refactor
- let action modules handle async processing
- moved async into base action class's module exec
- action plugins can now run final action as async
- actually skip copy if base skips
- fixed normal for new paths
- ensure internal stat is never async
- default poll to 10 as per docs
- added hint for callback fix on poll
- restructured late tmp, now a pipeline query
- moving action handler to connection as networking does
- fixed network assumption invocation is always passed
- centralized key cleanup, normalized internal var
- _supress_tmpdir_delete now in _ansible_xxx and gets removed from results
- delay internal key removal till after we use em
- nicer tmp removing, using existing methods
- moved cleanup tmp flag to mking tmp func
At the moment, this change will use EPoll on Linux, KQueue on *BSDs,
etc, so it should alleviate problems with too many open file
descriptors.
* Bundle a copy of selectors2 so that we have the selectors API everywhere.
* Add licensing information to selectors2 file so it's clear what the
licensing terms and conditions are.
* Exclude the bundled copy of selectors2 from our boilerplate code-smell test
* Rewrite ssh_run tests to attempt to work around problem with mocking
select on shippable
Fixes#14143
* Fix a test failure on Python 3.6

The added unit tests contain more examples.
This commit also takes care to avoid "no newline at EOF" warnings when
no_log is in effect, and also when modules return dicts rather than
strings. (It also removes trailing whitespace from using json
serialization when diffing dicts, because I hate trailing whitespace in
Python source files, even if they're test files.)
This plugin can be used with the lpass cli interface for lastpass.
[lastpass-cli](https://github.com/lastpass/lastpass-cli)
Example:
Add a lookup to your playbooks/variables somewhere:
```
some_variable: "{{ lookup('lastpass','Some Lastpass entry name or ID', field='username') }}"
```
Usage:
* start a lpass session prior to using ansible
* run ansible
* logout when finished
```
lpass login user@domain.com
ansible-playbook foo.yml
lpass logout
```
Since we no longer use a post-validated task in _process_pending_results, we
need to be sure to template fields used in original_task as they are raw and
may contain variables.
This patch also moves the handler tracking to be per-uuid, not per-object.
Doing it per-object had implications for the above due to the fact that the
copy of the original task is now being used, so the only sure way is to track
based on the uuid instead.
Fixes#18289
* Fix synchronize retries
The synchronize module munges its task args on every invocation of
run(). This was problematic because the munged data was not fit for use
by a second pass of the synchronize module. Correct this by using a copy
of the task args on every invocation of run() so that the original args
are not affected.
Local testing using this playbook seems to confirm that things work as
expected:
- hosts: all
tasks:
- delay: 2
register: task_result
retries: 1
until: task_result.rc == 0
synchronize:
dest: /tmp/out
mode: pull
src: /tmp/nonexistent/
fixes#18281
* Update synchroncization fixture assertions
When we started operating on a copy of the task args the test assertions
were no longer asserting things about the munged state but of the
pristine state. Convert the copy of task args to a class member so that
it can be compared against later in testing and update the assertions to
check this munged copy.
* Shuffle objects around for cleaner testing
Attach the temporary args dict to the task rather than the action as
this makes updating the existing tests cleaner.
This adds back the change to the network_cli plugin. Ths change adds
the ensure_connect decorator to the open_shell() method to make sure
the connection is valid before trying to open a shell.
The issue was due to the addition of the decorator that will call
_connect() when there is no connection. The _connect() method should
have been mocked in the test case. This commit fixes the test
case as well
Change was originally reverted in c414ded69a
* Replace pipes.quote for shlex_quote
* More migration of pipes.quote to shlex_quote
Note that we cannot yet move module code over. Modules have six-1.4
bundled which does not have shlex_quote. This shouldn't be a problem as
the function is still importable from pipes.quote. It's just that this
has become an implementation detail that makes us want to import from
shlex instead.
Once we get rid of the python2.4 dependency we can update to a newer
version of bundled six module-side and then we're free to use
shlex_quote everywhere.
Previous changes addressed a corner case, which unfortunately introduced
another bug. This patch adds a new flag to the host state (did_rescue) which
is set to true when the rescue portion of a block completes. This flag is
then checked in _check_failed_state() when the fail_state != FAILED_NONE.
This lead to the discovery of another bug - current strategies are not advancing
hosts to ITERATING_COMPLETE after doing a peek at the next task, leaving the
host state in the run_state of the final task. To address this, before gathering
the list of failed hosts in StrategyBase.run(), a final pass through the iterator
for all hosts is done to ensure each host is in its final state. This way, no
strategy derived from StrategyBase has to worry about it and it's handled.
Fixes#17983
- Use assertRaisesRegexp to make sure correct exceptions are raised.
- Set docker_command to avoid docker dependency (skips find_executable).
- Use a fake path for docker_command to make sure mock.patch is working.
- 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.
Nothing seems to use this now.

If the sftp fails, roll over to scp by default. This saves users
from having to know about the scp_if_ssh method when sftp is broken
on the remote host.
* 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%
