* sends the serialized play_context into an already established connection
* hooks the alarm_handler() method in the connection plugin if it exists
* added configuration options for connect interval and retries
* adds syslog logging to Server() instance
This update will send the updated play_context back into an already
established connection in case privilege escalation / descalation activities
need to be performed. This change will also hook the alarm_handler() method
in the connection instance (if available) and call it in case of a
sigalarm raised.
This update adds two new configuration options
* PERSISTENT_CONNECT_INTERVAL - time to wait in between connection attempts
* PERSISTENT_CONNECT_RETRIES - max number of retries
* updates paramiko_ssh to auto add keys
* updates constants with new config options
This commit adds a new feature that will allow paramiko to automatically
accept and save a host ssh key. This feature is controlled by the
`host_key_auto_add` config setting in the paramiko section. The default
is False to maintain current functionality. It also includes a new
setting `look_for_keys` with the default to False for maintaining current the
current setting.
* ANSIBLE_SSH_CONTROL_PATH_DIR option added
This removes the hardcoded value ( $HOME/.ansible/cp ) from ssh.py.
User is able to change the ControlPath directory ( the one that replaces %(directory)s ).
Fixes#18325
* Added config option in ansible.cfg
This is better API as the booleans could conflict with each other.
If the config value is a string, make sure to return it as a text string
rather than a byte string.
As recently there was back-and-forth with this hardcoded value
(0.001 -> 0.01 -> 0.005), obviousely the optimal value for it depends on
Ansible usage scanario and is better to be configurable.
This patch adds a new config option in DEFAULT section,
`internal_poll_interval`, with default of 0.001 corresponding to the
value hardcoded in Ansible v2.1.
This config option is then used instead of hardcoded values where
needed.

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
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%
* These can still race when multiple ansible processes are created at
the same time.
* Reverse order of expanduser and expandvars in unfrakpath(). So that
tildes in environment variables will be handled.
This makes Ansible no longer set LC_ALL for remote systems. It is up to
the individual modules to set LC_ALL if they need it for screenscraping
the output from a program.
This is the 2.2 followup for #15138
AIX ssh does not seem to like compression, moved it to ssh_args
to allow making it configurable. Note that those using ssh_args
already will need to add it explicitly to keep compression.
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
* 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
porting @dominis 's ansible-shell tool from 1.9 and integrating it into ansible

Pipelining is a *significant* performance benefit, because each task can
be completed with a single SSH connection (vs. one ssh connection at the
start to mkdir, plus one sftp and one ssh per task).
Pipelining is disabled by default in Ansible because it conflicts with
the use of sudo if 'Defaults requiretty' is set in /etc/sudoers (as it
is on Red Hat) and su (which always requires a tty).
We can (and already do) make sudo/su happy by using "ssh -t" to allocate
a tty, but then the python interpreter goes into interactive mode and is
unhappy with module source being written to its stdin, per the following
comment from connections/ssh.py:
# we can only use tty when we are not pipelining the modules.
# piping data into /usr/bin/python inside a tty automatically
# invokes the python interactive-mode but the modules are not
# compatible with the interactive-mode ("unexpected indent"
# mainly because of empty lines)
Instead of the (current) drastic solution of turning off pipelining when
we use a tty, we can instead use a tty but suppress the behaviour of the
Python interpreter to switch to interactive mode. The easiest way to do
this is to make its stdin *not* be a tty, e.g. with cat|python.
This works, but there's a problem: ssh will ignore -t if its input isn't
really a tty. So we could open a pseudo-tty and use that as ssh's stdin,
but if we then write Python source into it, it's all echoed back to us
(because we're a tty). So we have to use -tt to force tty allocation; in
that case, however, ssh puts the tty into "raw" mode (~ICANON), so there
is no good way for the process on the other end to detect EOF on stdin.
So if we do:
echo -e "print('hello world')\n"|ssh -tt someho.st "cat|python"
…it hangs forever, because cat keeps on reading input even after we've
closed our pipe into ssh's stdin. We can get around this by writing a
special __EOF__ marker after writing in_data, and doing this:
echo -e "print('hello world')\n__EOF__\n"|ssh -tt someho.st "sed -ne '/__EOF__/q' -e p|python"
This works fine, but in fact I use a clever python one-liner by mgedmin
to achieve the same effect without depending on sed (at the expense of a
much longer command line, alas; Python really isn't one-liner-friendly).
We also enable pipelining by default as a consequence.
The code isn't sophisticated enough to understand lists and dicts yet.
This mirrors how 1.9.x handled non-string items so its not a regression.
One portion of a fix for #12976
also remove condition to bypass setting user if user matches current user
this enables forcing user when set to the same user as current user and ignoring .ssh/config
while keeping .ssh/config with current user if nothing is specified.
The earlier code behaved exactly as though this default had been set,
but it was actually handled as a(n unnecessary) special case inside the
connection plugin, rather than set as an explicit default.
If the default is overriden either in ansible.cfg or the environment,
the new code will continue to work (in fact, it won't know or care,
since it just uses the value set in the PlayContext).
This is submitted as a separate commit for easier review to address
backwards-compatibility concerns.
* allow global no_log setting, no need to set at play or task level, but can be overriden by them
* allow turning off syslog only on task execution from target host (manage_syslog), overlaps with no_log functionality
* created log function for task modules to use, now we can remove all syslog references, will use systemd journal if present
* added debug flag to modules, so they can make it call new log function conditionally
* added debug logging in module's run_command
The event loop (even after it was brought into one place in _run in the
previous commit) was hard to follow. The states and transitions weren't
clear or documented, and the privilege escalation code was non-blocking
while the rest was blocking.
Now we have a state machine with four states: awaiting_prompt,
awaiting_escalation, ready_to_send (initial data), and awaiting_exit.
The actions in each state and the transitions between then are clearly
documented.
The check_incorrect_password() method no longer checks for empty strings
(since they will always match), and check_become_success() uses equality
rather than a substring match to avoid thinking an echoed command is an
indication of successful escalation. Also adds a check_missing_password
connection method to detect the error from sudo -n/doas -n.
This change is similar to https://github.com/ansible/ansible/pull/10465
It extends the logic there to also support none types. Right now if you have
a '!!null' in yaml, and that var gets passed around, it will get converted to
a string.
eg. defaults/main.yml
```
ENABLE_AWESOME_FEATURE: !!null # Yaml Null
OTHER_CONFIG:
secret1: "so_secret"
secret2: "even_more_secret"
CONFIG:
hostname: "some_hostname"
features:
awesame_feature: "{{ ENABLE_AWESOME_FEATURE}}"
secrets: "{{ OTHER_CONFIG }}"
```
If you output `CONFIG` to json or yaml, the feature flag would get represented in the output
as a string instead of as a null, but secrets would get represented as a dictionary. This is
a mis-match in behaviour where some "types" are retained and others are not. This change
should fix the issue.
I also updated the template test to test for this and made the changes to v2.
Added a changelog entry specifically for the change from empty string to null as the default.
Made the null representation configurable.
It still defaults to the python NoneType but can be overriden to be an emptystring by updating
the DEFAULT_NULL_REPRESENTATION config.
* enable batch mode (configurable with a config option, on by default)
for sftp transfers, so we can catch errors more easily
* general cleanup in the local connection plugin and fetch action plugin
