2e003adb added the ability for tasks using any_errors_fatal to fail
when there were unreachable hosts. However that patch used the running
unreachable hosts data rather than the results from the current task,
which causes failures when any run_once or BYPASS_HOST_LOOP task is hit
after an unreachable host causes a failure. This patch corrects that by
using the current set of results to determine if any hosts were
unreachable during the last task only.

This adds a action plugin that will allow config and template modules
to be merged into a single module. Once completed this will supercede
the net_template action plugin.

do for regular tasks
* Clean up the logic used to find a given handler, which is greatly

Closes#16189
Our custom encoder for the to_json filter was simply returning the
object if it was not a HostVars object, leading in some cases to a
TypeError when the data contained an undefined variable. This lead
to an odd error message being propagated up, so we now properly catch
this as an undefined variable error.
Fixes#15610
Due to the fact that roles may be instantiated with different sets of
params (multiple inclusions of the same role or via role dependencies),
simply tracking notified handlers by name does not work. This patch
changes the way we track handler notifications by using the handler
object itself instead of just the name, allowing for multiple internal
instances. Normally this would be bad, but we also modify the way we
search for handlers by first looking at the notifying tasks dependency
chain (ensuring that roles find their own handlers first) and then at
the main list of handlers, using the first match it finds.
This patch also modifies the way we setup the internal list of handlers,
which should allow us to correctly identify if a notified handler exists
more easily.
Fixes#15084
This removes the extra layer of quotes around values in the 'args' file.
These quotes were there before the pipes.quote() call was added, but
were not removed, resulting in too much quoting.
Problem: When setting the file permissions on the remote server for
unprivileged users ansible expects that a chown will fail for unprivileged
users. For some systems (e.g. HP-UX) this is not the case.
Solution: Change the order how ansible sets the remote permissions.
* If the remote_user sudo's to an unprivileged user then we attempt to
grant the unprivileged user access via file system acls.
* If granting file system acls fails we try to change the owner of the
file with chown which only works in case the remote_user is privileged
or the remote systems allows chown calls by unprivileged users (e.g.
HP-UX)
* If the chown fails we can set the file to be world readable so that
the second unprivileged user can read the file. Since this could allow
other users to get access to private information we only do this
ansible is configured with "allow_world_readable_tmpfiles" in the
ansible.cfg
Symlinks inside of the chroot were failng because we weren't able to
determine if they were pointing to a real file or not. We could write
some complicated code to walk the symlink path taking into account where
the root of the tree is but that could be fragile. Since this is just
a sanity check, instead we just assume that the chroot is fine if we
find that /bin/sh in the chroot is a symlink. Can revisit if it turns
out that many chroots have a /bin/sh that's a broken symlink.
Fixes#16097
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.
* Give a module the possibility to known its own name
This is useful for logging and reporting and fixes the longstanding problem with syslog-messages:

Jun 1 17:32:03 moria ansible-copy: Invoked with ...
This fixes#15830
* Rename the internal name from module.ansible_module_name to module._name
This allows the PlaybookExecutor to receive more information regarding
what happened internal to the TaskQueueManager and strategy, to determine
things like whether or not the play iteration should stop.

* Port urls.py to python3
Fixes (largely normalizing byte vs text strings) for python3

This fixes the error in https://github.com/ansible/ansible/issues/16125
but there may be higher level issues that should be fixed as well (other
modules might be able to cause status fields like failed and changed to
return a censored string instead of a bool). So leaving 16125 open for
now.
* readd the service action plugin, was removed cause it created unexpected fact gathering and there are no split service plugins that would make this useful (yet)
Revert "removed action plugin as service facts and separate modules don't work yet and this forces gathering facts"
This reverts commit 7368030651.
* now only does minimal fact gathering
With some earlier changes, continuing to forward failed hosts on
to the iterator with each TQM run() call was causing plays with
max_fail_pct set to fail, as hosts which failed in previous plays
were counting those old failures against the % calculation.
Also changed the linear strategy's calculation to use the internal
failed list, rather than the iterator, as this now represents the
hosts failed during the current run only.
The change is needed to support the multiple include statements
inside the jinja2 template file, as in '{% include ['another.j2'] %}'.
statement. I need this capability, as OpenSwitch `switch` role needs
to handle multiple *.j2 files and supporting the include statement
inside jinja2 file is essential, otherwise I need to combine multiple
template files into a single file, which easily causes conflicts
between developers working on different parts of the teamplate, ports
and interface.
* more robust hashi_vault module, and allow querying specific field in secret-dict
* allow fetching entire secret dict with trailing ':'
* process comment by bcoca for PR #13690
When using run_once, there is only one dict of facts so passing that
to the VariableManager results in the fact cache containing the same
dictionary reference for all hosts in inventory. This patch fixes that
by making sure we pass a copy of the facts dict to VariableManager.
Fixes#14279
In the free strategy, we mark a host as blocked when it has work to do
(the PlayIterator returns a task) to prevent multiple tasks from being sent
to the host. However, we check for role duplicates after setting the blocked
flag, but were not clearing that when the task was skipped leading to an
infinite loop. This patch corrects that by clearing the blocked flag when
the task is skipped.
Fixes#15681
* Don't filter hosts remaining based on their failed state. Instead rely
on the PlayIterator to return None/ITERATING_COMPLETE when the host is
failed.
* In the free strategy, make sure we wait outside the host loop for all
pending results to be processed.
* Use the internal _set_failed_state() instead of manually setting things
when a failed child state is hit
Fixes#15623
* When var name is the same as var content, try to template it before reporting that var is not defined.
Add asserts in test_var_blending to check this special corner case.

It wasn't doing anything that a literal couldn't do and used
unicode_escape which only understands latin1 (The author of the code
seems to have thought it took an encoding argument but it looks like
that was silently ignored.)
This was reinitialized every time we forked before so we weren't sharing
the same Locks. It also was not accounting for modules which were
directly invoked by an action plugin instead of going through the
strategy plguins.
* Make ziploader's ansible and ansible.module_utils libraries into
namespace packages.
* Move __version__ and __author__ from ansible/__init__ to

version info then those won't be available.
* In ziplaoder, move the version ito ANSIBLE_CONSTANTS.
* Change PluginLoader to properly construct the path to the plugins even

hacky CLIXML parsing of stderr
Previously we were first checking the fail/run state of the child

whether the child state is failed or complete before changing the failed/
run state within the current block.
Fixes#14324
This update will attempt to guess the file format based on the template
extension if the format argument isnt set. It will also set the commit
comment to the task name if the comment isnt' explicitly defined.
* Don't rely on username to check for root privileges
The SSH username isn't a reliable way to check if we've got root privileges on
the remote system (think "toor" on FreeBSD). Because of this check, Ansible
previously tried to use the fallback solutions for granting file access (ACLs,
world-readable files) even on systems where it had root privileges when the
remote username didn't match the literal string "root".
Instead of running checks on the username, just try using `chmod` in any case
and fall back to the previous "non-root" solution when that fails.
* Fail if we are root and changing ownership failed
Since this code is security sensitive we document exactly the expected
permissions of the temporary files once this function has run. That way
if a flaw is found in one end-result we know more precisely what scenarios
are affected and which are not.
If add_host is performed with hostname existing in inventory, but
not yet accessed and put in inventory cache, additional host with
same hostname and different uuid is created, causing patterns to
misbehave.
The first filter is regex_search which adds the ability to do a regex
search on a fact. The filter supports returning either all capture groups
or a set of capture groups (either by index or named).
Example usage of regex_search filter
debug: msg="{{ out.stdout[0] | regex_search('image version. (?P<test>\d+).(\d+)', '\\g<test>', '\\2' ) }}"
The second filter is regex_findall with adds the capability to do a
regex findall on a fact or variable and return all occurances of a pattern.
debug: msg="{{ out.stdout[0] | regex_findall('vlan (\d+)' }}"
The filter supports two addtional keyword arguments, ignorecase=[true, false]
and multiline=[true, false]

- get_real_file will decrypt vault encrypted files and return a path to
a temporary file.
- cleanup_real_file will remove a temporary file created previously with
get_real_file
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
Due to an apparent race condition while using pty's on a heavily loaded
system, rarely a request to create a temp directory returns an empty
string rather than the newly created path, causing an error. Disabling
forced pty's appears to resolve the issue, so this patch modifies the
mkdtemp remote call not use -tt as we're not escalating privileges and
thus no pty is required.
Fixes#13876
* Remove workaround for fixed bug.

* 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

I was surprised to see complete file content in the (JSON) task output when
in diff-mode. Since we see the diff anyhow, there's no need to send everything
on screen.
`ansible_failed_task`:
Contains the task data, essentially a serialized view of the Task() object.
`ansible_failed_result`:
Contains the result of the task failure, which is identical in function
to registering the result. Doing so automatically like this saves the user
from having to register every result in a block and then trying to figure
out which result had the failure
Similar to the way try/except/finally work, these variables will not be
available in the `always` portion of a block unless there is a corresponding
`rescue` first.
Fixes#12341
The changes to chown/chmod were broken on Mac (-R was being appended to the end of the command- OSX requires it before the file list).
A number of base action remote setup commands were also blindly proceeding without checking for success. Added error raises for unrecoverable failure cases.
If we're not delegating then we change _connection into a local
connection midway through the file but we don't change
_play_context.connection (no need to alter that). When we later check
it in process_remote() we need to know the actual connection, not the
connection that we thought we were going to use at the start of run().
So we have to use _connection.transport in process_remote(). The rest
of the places could use either one (because we have not yet changed to
a local connection) but we go ahead and switch those to
_connection.transport as well to avoid confusion in the future.
Fixes https://github.com/ansible/ansible-modules-core/issues/3136
* class_only was a keyword arg of get() and all() that was mistakenly
passed on to Plugins. Be sure to strip it from the keyword args
before instantiating Plugins. (Reworked API probably should either
not instantiate Plugins or take the args for the Plugin as a separate
list and a dict.)
* Checking required base_classes was only done in get() and only if
class_only was False (ie: that Plugin was instantiated). This meant
that different plugins could be found depending on whether the call
was to .get() or to all() and whether it was for classes or instances.
Fixed so that required base_classes are always checked.
This implements solution #1 in the proposal #14860.
It only shows the diff if the task induced a change, which means that if the changed_when control overrides the task, not diff will be produced.
See #14860 for a rationale and the use-case.
This commit adds the multiline flag to the regexp search and match test
plugin. It defaults to re.M = False for backwards compatibility. To use
the multiline feature add multiline=True to the test filter

main_q is not used anywhere in the codebase.
It is created in TaskQueueManager._initialize_processes, bundled with rslt_q
into TaskQueueManger._workers, later unwrapped in StrategyBase but not used.
This queue is closed in TaskQueueManger._cleanup_processes.
Historically, it is passed as a init parameter into WorkerProcess,
introduced in 62d7956, but this behavior is changed in 120b9a7.

This commit changes the key the ops_template will search for in order

When checksums of local and remote files match, and when follow = True,
determine if remote destination is a symlink. If so, de-reference it and
pass the link target to the file module as 'dest'.
This change fixes an edge case in file copy behavior when:
- 'dest' is a symlink to some other file ('realdest')
- follow = True
- the checksums of the source file, 'src', and the symlink target, 'realdest',
match.
Because the checksums match, the copy module is skipped and the file module
is invoked directly with 'dest' = the symlink, and 'src' = the source of the
copy module, whether that source is present on the target machine or not.
When 'src' doesn't exist on the target machine, this leads to an error that
looks like this because it can't change the target of the symlink:
TASK [copy] ********************************************************************
fatal: [192.168.56.101]: FAILED! => {"changed": false, "checksum": "f572d396fae9206628714fb2ce00f72e94f2258f", "failed": true, "gid": 1000, "group": "ajdecon", "mode": "0777", "msg": "src file does not exist, use \"force=yes\" if you really want to create the link: /tmp/issue1568/dest_dir/source", "owner": "ajdecon", "path": "/tmp/issue1568/dest_dir/dest", "size": 8, "src": "source", "state": "link", "uid": 1000}
When the path 'src' *does* exist on the target machine, the file module makes
this the symlink "dest -> src" instead of "dest -> realdest"... even if the
checksum of 'src' on the target machine is different from the checksum of 'src'
on the machine where Ansible is running.

So far, when a 'diff' dict is returned with module results, it is
checked for 'before' and 'after' texts, which are processed in
_get_diff() by python difflib. This generates the changes to display
when CLI users specify --diff.
However, some modules will generate changes that cannot easily be
expressed in a conventional diff. One example is the output of the
synchronize module, which presents changed files in a common log format
as in `rsync --itemize-changes`.
Add a check for a diff['prepared'] key, which can contain prepared diff text
from modules.
* In 2.0.0.x become was reversed for synchronize. It was happening on
the local machine instead of the remote machine. This restores the
ansible-1.9.x behaviour of doing become on the remote machine.
However, there's aspects of this that are hacky (no hackier than
ansible-1.9 but not using 2.0 features). The big problem is that it
does not understand any become method except sudo. I'm willing to use
a partial fix now because we don't want people to get used to the
reversed semantics in their playbooks.

Previously, the lookup plugin passes all its keyword arguments to
credstash's `getSecret`; while this works for passing the standard
parameters (version, region and table), this does not allow passing
a dictionary of key-value pairs as `getSecret`'s context parameter.
Instead, pop `version`, `region` and `table` from `kwargs`, supplying
the default value if they are not defined, and pass the rest of the `kwargs`
as the `context` parameter.

This was added in 1.9 and 2.0 tried to copy, but since it cannot
obey no_log restrictions I commented it out. I did not remove as
it is still very useful for module invocation debugging.
Environments were not being templated individually, so a variable environment
value was causing the exception regarding dicts to be hit. Also, environments
as inherited were coming through with the tasks listed first, followed by the
parents, so they were being merged backwards. Reversing the list of environments
fixed this.
Also fixes a bug where we were passing an incorrect number of parameters to
_do_handler_run() when processing an include file in a handler task/block.

We were logging the command to be executed many times, which made debug
logs very hard to read. Now we do it only once.
Also makes the logged ssh command line cut-and-paste-able (the lack of
which has confused a number of people by now; the problem being that we
pass the command as a single argument to execve(), so it doesn't need an
extra level of quoting as it does when you try to run it by hand).
This should fix issues with fish shell users as && and || are
not valid syntax, fish uses actual 'and' and 'or' programs.
Also updated to allow for fish backticks pushed quotes to subshell,
fish seems to handle spaces w/o them.
Lastly, removed encompassing subshell () for fish compatibility.

* Pass the playbook instance to v2_on_playbook_start
* Add a _file_name instance attribute to the playbook
At its most basic, this is nothing more than an array or hash lookup,
but when used in conjunction with map, it is very useful. For example,
while constructing an "ssh-keyscan …" command to update known_hosts on
all hosts in a group, one can get a list of IP addresses with:
groups['x']|map('extract', hostvars, 'ec2_ip_address')|list
This returns hostvars[a].ec2_ip_address, hostvars[b].ec2_ip_address, and
so on. You can even specify an array of keys for a recursive lookup, and
mix string and integer keys depending on what you're looking up:
['localhost']|map('extract', hostvars, ['vars','group_names',0])|first
== hostvars['localhost']['vars']['group_names'][0]
== 'ungrouped'
Includes documentation and tests.
The comment was taken literally from lib/plugins/strategy/linear.py and
makes no sense in free.py where we have no noop tasks.
Also update the debug messages.
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.
If we request escalation with a password, we start in expecting_prompt
state. If the escalation then succeeds without the password, i.e., the
become_success response arrives, we must explicitly move into the next
state (awaiting_escalation, which immediately goes into ready_to_send),
so that we no longer try to apply the timeout.
Otherwise, we would leak the success notification and eventually
timeout. But if the module response did arrive before the timeout
expired, the "process has already exited" test would do the right
thing by accident (which is why it didn't fail more often).
Fixes#13289
This was caused by accessing the cache using the passed in mod_type
rather than the suffix that we calculate with knowledge of whether this
is a module or non-module plugin.
Previously, we were filtering the task list on tags for each host
that was including the file, based on the idea that the variables
had to include the host information. However, the top level task
filtering is play-context only, which should also apply to the
included tasks. Tags cannot and should not be based on hostvars.
This callback plugin will generate json objects to be sent to the
logentries service for auditing/debugging purposes.
To use:
Add this to your ansible.cfg file in the defaults block
[defaults]
callback_plugins = ./callback_plugins
callback_stdout = logentries
callback_whitelist = logentries
Copy the callback plugin into the callback_plugings directory
Either set the environment variables
export LOGENTRIES_API=data.logentries.com
export LOGENTRIES_PORT=10000
export LOGENTRIES_ANSIBLE_TOKEN=dd21fc88-f00a-43ff-b977-e3a4233c53af
Or create a logentries.ini config file that sites next to the plugin with the following contents
[logentries]
api = data.logentries.com
port = 10000
tls_port = 20000
use_tls = no
token = dd21fc88-f00a-43ff-b977-e3a4233c53af
It was set to match the SSH connect timeout. Unfortunately, they would
race when ssh fails to connect, and the connect timeout usually failed.
This led to some misleading error messages.
Fixes#12916
Code for a plugin is usually loaded by a PluginLoader(), and henceforth
available from self._module_cache, which prevents duplicate loading.
However there are situations (e.g. where one action plugin imports code
from another one) where the plugin module might be already imported (and
resident in sys.modules), but not present in the PluginLoader's
_module_cache, which causes imp.load_source() to effectively reload the
module, overwriting global class declarations and causing subtle latent
bugs.

I PR'd a change to pywinrm to allow server certs to be ignored; but it's only on the SSL transport (which we were previously ignoring). For this to work more generally, we're also now pulling the named ansible_winrm_* args from the merged set of host/group vars, not just host_vars.

The first call to persisting facts would work due to the assignment of a
MutableMapping calling __setitem__ but subsequent module fact data would
not be propogated to the fact cache plugins because update() doesn't
invoke __setitem__. This changes the behavior a little bit and ensures
set() is called on cache plugins.

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.
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).

Removed deletion of salt param from lookup file by 'password' lookup_filter.
Old behaviour leads to constant changed status when two tasks uses same lookup,
one with 'encrypt' parameter, and other without.
For example:
tasks:
- name: Create user
user:
password: "{{ lookup('password', inventory_dir + '/creds/user/pass' ncrypt=sha512_crypt) }}"
...
# Lookup file 'creds/user/pass' now contain password with salt
- name: Create htpasswd
htpasswd:
password: "{{ lookup('password', inventory_dir + '/creds/user/pass') }}"
...
# Salt gets deleted from lookup file 'creds/user/pass'
# Next run of "Create user" task will create it again and will have 'changed' status
* Disable su as it's not currently working 100% (and was disabled in v1).
* Move BUFSIZE out of the class to match other conenction plugins
* _connect shouldn't return self.
This is also peripheral to what _build_command needs, can be improved
and tested independently, and so makes more sense in a separate method.
This commit doesn't change any functionality (and I've verified that it
works with the various combinations: control_path set in ansible.cfg,
ssh_args adding or not adding ControlMaster/ControlPersist, etc.).
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.)
Also get pipelining working for people who look to chroot as an example
for their own connection plugins
Note: In the latest v2 API, action handles become but chroot doesn't
reliably handle become. Maybe we need to add a has_become attribute
that the action can display an appropriate error.
* 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
There doesn't appear to be anything that actually uses tmp_path in the
connection plugins so we don't need to pass that in to exec_command.
That change also means that we don't need to pass tmp_path around in
many places in the action plugins any more. there may be more cleanup
that can be done there as well (the action plugin's public run() method
takes tmp as a keyword arg but that may not be necessary).
As a sideeffect of this patch, some potential problems with chmod and
the patch, assemble, copy, and template modules has been fixed (those
modules called _remote_chmod() with the wrong order for their
parameters. Removing the tmp parameter fixed them.)
The process is already gone, so there's not going to be any new data
showing up on its stderr; we only want to make sure that we haven't
missed something that was already written. So polling once is enough.
This change is motivated by an ssh oddity: when ControlPersist is
enabled, the first (i.e. master) connection goes into the background; we
see EOF on its stdout and the process exits, but we never see EOF on its
stderr. So if we ran a command like this:
ANSIBLE_SSH_PIPELINING=1 ansible -T 30 -vvv somehost -u someuser -m command -a whoami
We would first do select([stdout,stderr], timeout) and read the command
module output, then select([stdout,stderr], timeout) again and read EOF
on stdout, then select([stderr], timeout) AGAIN (though the process has
exited), and select() would wait for the full timeout before returning
rfd=[], and then we would exit. The use of a very short timeout in the
code masked the underlying problem (that we don't see EOF on stderr).
It's always preferable to call select() with a long timeout so that the
process doesn't use any CPU until one of the events it's interested in
happens (and then select will return independent of elapsed time).
(A long timeout value means "if nothing happens, sleep for up to <x>";
omitting the timeout value means "if nothing happens, sleep forever";
specifying a zero timeout means "don't sleep at all", i.e. poll for
events and return immediately.)
This commit uses a long timeout, but explicitly detects the condition
where we've seen EOF on stdout and the process has exited, but we have
not seen EOF on stderr. If and only if that happens, it reruns select()
with a short timeout (in practice it could just exit at that point, but
I chose to be extra cautious). As a result, we end up calling select()
far less often, and use less CPU while waiting, but don't sleep for a
long time waiting for something that will never happen.
Note that we don't omit the timeout to select() altogether because if
we're waiting for an escalation prompt, we DO want to give up with an
error after some time. We also don't set exceptfds, because we're not
actually acting on any notifications of exceptional conditions.
Without this, we could execute «ssh -q ...» and call select(), which
would timeout after the default 10s, and only then send initial data.
(This is a relic of the earlier change where we always ran ssh with
-vvv, so the situation where it would sit quietly never happened in
practice; but this would have been the right thing to do even then.)
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.
The main exec_command/put_file/fetch_file methods now _build_command and
call _run to handle input from/output to the ssh process. The purpose is
to bring connection handling together in one place so that the locking
doesn't have to be split across functions.
Note that this doesn't change the privilege escalation and connection IO
code at all—just puts it all into one function.
Most of the changes are just moving code from one place to another (e.g.
from _connect to _build_command, from _exec_command and _communicate to
_run), but there are some other notable changes:
1. We test for the existence of sshpass the first time we need to use
password authentication, and remember the result.
2. We set _persistent in _build_command if we're using ControlPersist,
for later use in close(). (The detection could be smarter.)
3. Some apparently inadvertent inconsistencies between put_file and
fetch_file (e.g. argument quoting, sftp -b use) have been removed.
Also reorders functions into a logical sequence, removes unused imports
and functions, etc.
Aside: the high-level EXEC/PUT/FETCH description should really be logged
from ConnectionBase, while individual subclasses log transport-specific
details.
* Make LookupBase an abc with required methods (run()) marked as an
abstractmethod
* Mark methods that don't use self as @staticmethod
* Document how to implement the run method of a lookup plugin.
This fixes a failing unit test.
In actual use (which is still quite far), I'm not sure if bytes ->
unicode conversion should be done here (in which case the code will fail
with an AttributeError: 'bytes' object has no attribute 'readlines'), or
inside self._connection.exec_command() (in which case my change is
correct).
* Add exception handling when running PowerShell modules to provide exception message and stack trace.
* Enable strict mode for all PowerShell modules and internal commands.
* Update common PowerShell code to fix strict mode errors.
* Fix an issue with Set-Attr where it would not replace an existing property if already set.
* Add tests for exception handling using modified win_ping modules.
This adds a parse_address(pattern) utility function that returns
(host,port), and uses it wherever where we accept IPv4 and IPv6
addresses and hostnames (or host patterns): the inventory parser
the the add_host action plugin.
It also introduces a more extensive set of unit tests that supersedes
the old add_host unit tests (which didn't actually test add_host, but
only the parsing function).
This was commented out earlier because of the lack of interprocess
locking and prepare_writeable_dir in v2.
The locking was not needed: it could only protect against other siblings
of this process (since they were all locking a temporary file that was
opened in the parent), and those would be running as the same user and
with the same umask. Also, os.makedirs() tolerates intermediate paths
being created by other processes. For any other kind of error, both
locking and non-locking code paths would fail in the same way.
So all we really need to do is make sure we have write permissions.
(We also move the cp_dir handling code to where we actually set the
ControlPath ourselves; if the user has set it via ssh_*args already,
we don't need to bother.)

Be more explicit about why SSH arguments are added
This adds vvvvv log messages that spell out in detail where each SSH
command-line argument is obtained from.
Unfortunately, we can't be sure if, say, self._play_context.remote_user
is obtained from ANSIBLE_REMOTE_USER in the environment, remote_user in
ansible.cfg, -u on the command line, or an ansible_ssh_user setting in
the inventory or on a task or play. In some cases, e.g. timeout, we
can't even be sure if it was set by the user or just a default.
Nevertheless, on the theory that at five v's you can use all the hints
available, I've mentioned the possible sources in the log messages.
Note that this caveat applies only to the arguments that ssh.py adds by
itself. In the case of ssh_args and ssh_extra_args, we know where they
are from, and say so, though we can't say WHERE in the inventory they
may be set (e.g. in host_vars or group_vars etc.).

Allow ansible_ssh_args to be set as an inventory variable
Before this change, ssh_args could be set only in the [ssh_connection]
section of ansible.cfg, and was applied to all hosts. Now it's possible
to set ansible_ssh_args as an inventory variable (directly, or through
group_vars or host_vars) to selectively override the global setting.
Note that the default ControlPath settings are applied only if ssh_args
is not set, and this is true of ansible_ssh_args as well. So if you want
to override ssh_args but continue to set ControlPath, you'll need to
repeat the appropriate options when setting ansible_ssh_args.
(If you only need to add options to the default ssh_args, you may be
able to use the ansible_ssh_extra_args inventory variable instead.)

Add an ansible_ssh_extra_args inventory variable
This can be used to configure a per-host or per-group ProxyCommand to
connect to hosts through a jumphost, e.g.:
inventory:
[gatewayed]
foo ansible_ssh_host=192.0.2.1
group_vars/gatewayed.yml:
ansible_ssh_extra_args: '-o ProxyCommand="ssh -W %h:%p -q bounceuser@gateway.example.com"'
Note that this variable is used in addition to any ssh_args configured
in the [ssh_connection] section of ansible.cfg (so you don't need to
repeat the ControlPath settings in ansible_ssh_extra_args).
Replace .iteritems() with six.iteritems() everywhere except in
module_utils (because there's no 'six' on the remote host). And except
in lib/ansible/galaxy/data/metadata_template.j2, because I'm not sure
six is available there.
The lock file is (a temporary file) opened in the parent process, whose
open fd is inherited by the workers after fork, and passed down through
the PlayContext. Connection grows lock/unlock methods which can be used
by individual connection plugins.
Right now, we don't do any locking, but we still scan known_hosts files
twice per connection. That's completely unnecessary, and the proposed
solutions to the locking problem wouldn't need known_hosts scanning
anyway, so this code can go away.
dbd755e0 previously assigned the value to self._templar.environment.searchpath,
which is incorrect - it needs to be assigned to the environment.loader.searchpath
value instead.
