Instead of bombing out of the strategy, we now properly mark hosts failed
so that the play iterator can handle block rescue/always properly.
Fixes#14024
this was taken out in an effort to default to the user's shell but creates issues as this is not known ahead of time
and its painful to set executable and shell_type for all servers, it should only be needed for those that restrict the user
to specific shells and when /bin/sh is not available. raw and command may still bypass this by explicitly passing None.
fixes#13882
still conditional
This is because we pass arguments to non-newstyle modules via an
external file. If we pipeline, then the interpreter thinks it has to
run the arguments as the script instead of what is piped in via stdin.
keeps backwards compat by not removing the previouslly non grammer matching states
and introduces new ones so user can decide which one he wants
(or keep both and still be inconsistent to annoy those that care)
* Added additional methods to the iterator code to assess host failures
while also taking into account the block rescue/always states
* Fixed bugs in the free strategy, where results were not always being
processed after being collected
* Added some prettier printing to the state output from iterator

Adding an additional test for copy exclusion
Adds a negative test for the situation when an exclusion doesn't
exist in the target to be copied.

better api and tests added
* _copy_results = deepcopy for better performance
* _copy_results_exclude to deepcopy but exclude certain fields. Pop
fields that do not need to be deep copied. Re-assign popped fields
after deep copy so we don't modify the original, to be copied, object.
* _copy_results_exclude unit tests

remove uneeded deepcopy fields
* now module errors clearly state msg=MODULE FAILURE
* module's stdout and stderr go into module_stdout and module_stderr keys
which only appear during parsing failure
* invocation module_args are deleted from results provided by action
plugin as errors can keep us from overwriting and then disclosing info that
was meant to be kept hidden due to no_log
* fixed invocation module_args set by basic.py as it was creating different
keys as the invocation in action plugin base.
* results now merge
* Changed parse_addresses to throw exceptions instead of passing None
* Switched callers to trap and pass through the original values.
* Added very verbose notice
* Look at deprecating this and possibly validate at plugin instead
fixes#13608
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.
Fixes#13560
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.
fixes#13199
* Move self._tqm.load_callbacks() earlier to ensure that v2_on_playbook_start can fire
* 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.
