Using set_host_overrides() in the connection plugin to access the ssh
argument variables from the inventory didn't see group_vars/host_vars
settings, as noted earlier. Instead, we can set the correct values in
the PlayContext, which has access to all command-line options, task
settings, and variables.
The only downside of doing so is that the source of the settings is no
longer available in ssh.py, and therefore can't be logged. But the code
is simpler, and it actually works.
This change was suggested by @jimi-c in response to the FIXME in the
earlier commit.
Now we have the following ways to set additional arguments:
1. [ssh_connection]ssh_args in ansible.cfg: global setting, prepended to
every command line for ssh/scp/sftp. Overrides default ControlPersist
settings.
2. ansible_ssh_common_args inventory variable. Appended to every command
line for ssh/scp/sftp. Used in addition to ssh_args, if set above, or
the default settings.
3. ansible_{sftp,scp,ssh}_extra_args inventory variables. Appended to
every command line for the relevant binary only. Used in addition to
#1 and #2, if set above, or the default settings.
3. Using the --ssh-common-args or --{sftp,scp,ssh}-extra-args command
line options (which are overriden by #2 and #3 above).
This preserves backwards compatibility (for ssh_args in ansible.cfg),
but also permits global settings (e.g. ProxyCommand via _common_args) or
ssh-specific options (e.g. -R via ssh_extra_args).
Fixes#12576
Fixes another failing test.
(I don't want to do a global search/replace for 'basestring' because I
want to have unit tests covering each occurrence. When I run out of
existing failing tests, I'll try to write new ones.)
SSH pipelining can be a significant performance improvement, but it will
not work if sudoers is configured to requiretty. With this change, one
could have pipelining enabled in ansible.cfg, but use sudo to turn off
requiretty in a separate play (or task) where pipelining is disabled:
- hosts: foo
vars:
ansible_pipelining: no
tasks:
- lineinfile: dest=/etc/sudoers line='Defaults requiretty' state=absent
sudo_user: root
(Note that sudoers has a complicated syntax, so the above lineinfile
invocation may be too simplistic for production use; but the point is
that a separate play can do something to disable requiretty.)
* 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
Due to the way we're now calculating delegate_to, if that value is based
on a loop variable ('item') we need to calculate all of the possible
delegated_to variables for that loop.
Fixes#12499
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.
Now, instead of relying on hostvars on the executor side, we compile
the vars for the delegated to host in a special internal variable and
have the PlayContext object look for things there when applying task/
var overrides, which is much cleaner and takes advantage of the code
already dealing with all of the magic variable variations.

Use six.moves.range instead (aliased to xrange on Python 2, aliased to
range on Python 3).
Also I couldn't resist replacing the elaborate chr/ord/randrange dance
with the simpler random.choice(string.ascii_lowercase) that was already
used elsewhere in the Ansible codebase.
