When there are spaces in command args passed as a list,
then run_command and underlying subprocess fails.
This can be overcome by passing command as string rather than list.

Python sets the SIGPIPE handler to SIG_IGN. On execv() signal handlers are
reset to their defaults, EXCEPT those that are SIG_IGN which are left ignored.
In Python 3 subprocess.popen explicitly resets the SIGPIPE handler to SIG_DFL,
but unfortunately in Python 2.7 it does not. This leads to subprocesses being
executed with SIGPIPE ignored. This is often a problem with bash scripts which
rely on SIGPIPE to terminate commands in a pipe, but can easily be a problem
with other applications.
This implements the Python 3 behaviour for Python 2.7 by using a preexec_fn.
* Remove use of simplejson throughout code base. Fixes#42761
* Address failing tests
* Remove simplejson from contrib and other outlying files
* Add changelog fragment for simplejson removal
* actually check we can run scm command for roles
* a better error message than file not found
* more narrow exception hanlding
* refactor common functions for more extended use and further 'basic.py' separation
Now that we don't need to worry about python-2.4 and 2.5, we can make
some improvements to the way AnsiballZ handles modules.
* Change AnsiballZ wrapper to use import to invoke the module
We need the module to think of itself as a script because it could be
coded as:
main()
or as:
if __name__ == '__main__':
main()
Or even as:
if __name__ == '__main__':
random_function_name()
A script will invoke all of those. Prior to this change, we invoked
a second Python interpreter on the module so that it really was
a script. However, this means that we have to run python twice (once
for the AnsiballZ wrapper and once for the module). This change makes
the module think that it is a script (because __name__ in the module ==
'__main__') but it's actually being invoked by us importing the module
code.
There's three ways we've come up to do this.
* The most elegant is to use zipimporter and tell the import mechanism
that the module being loaded is __main__:
* 5959f11c9d/lib/ansible/executor/module_common.py (L175)
* zipimporter is nice because we do not have to extract the module from
the zip file and save it to the disk when we do that. The import
machinery does it all for us.
* The drawback is that modules do not have a __file__ which points
to a real file when they do this. Modules could be using __file__
to for a variety of reasons, most of those probably have
replacements (the most common one is to find a writable directory
for temporary files. AnsibleModule.tmpdir should be used instead)
We can monkeypatch __file__ in fom AnsibleModule initialization
but that's kind of gross. There's no way I can see to do this
from the wrapper.
* Next, there's imp.load_module():
* https://github.com/abadger/ansible/blob/340edf7489/lib/ansible/executor/module_common.py#L151
* imp has the nice property of allowing us to set __name__ to
__main__ without changing the name of the file itself
* We also don't have to do anything special to set __file__ for
backwards compatibility (although the reason for that is the
drawback):
* Its drawback is that it requires the file to exist on disk so we
have to explicitly extract it from the zipfile and save it to
a temporary file
* The last choice is to use exec to execute the module:
* https://github.com/abadger/ansible/blob/f47a4ccc76/lib/ansible/executor/module_common.py#L175
* The code we would have to maintain for this looks pretty clean.
In the wrapper we create a ModuleType, set __file__ on it, read
the module's contents in from the zip file and then exec it.
* Drawbacks: We still have to explicitly extract the file's contents
from the zip archive instead of letting python's import mechanism
handle it.
* Exec also has hidden performance issues and breaks certain
assumptions that modules could be making about their own code:
http://lucumr.pocoo.org/2011/2/1/exec-in-python/
Our plan is to use imp.load_module() for now, deprecate the use of
__file__ in modules, and switch to zipimport once the deprecation
period for __file__ is over (without monkeypatching a fake __file__ in
via AnsibleModule).
* Rename the name of the AnsiBallZ wrapped module
This makes it obvious that the wrapped module isn't the module file that
we distribute. It's part of trying to mitigate the fact that the module
is now named __main)).py in tracebacks.
* Shield all wrapper symbols inside of a function
With the new import code, all symbols in the wrapper become visible in
the module. To mitigate the chance of collisions, move most symbols
into a toplevel function. The only symbols left in the global namespace
are now _ANSIBALLZ_WRAPPER and _ansiballz_main.

* Only add exception/traceback on Python 3
On Python 2 the traceback could be any exception from the stack frame
and likely unrelated to the fail_json call.
On Python 3 the traceback is cleared outside any exception frame, so the
call always returns the most inner traceback (if any), and therefor is
most likely related to the fail_json call.
* Add uncertainty to traceback on Python 2
On Python 2 the last exception in the stack frame is being returned,
this could be unrelated to the actual error, especially if fail_json()
is called outside an except: block.
* Fix tmpdir on non root become
- also avoid exception if tmpdir and remote_tmp are None
- give 'None' on deescalation so tempfile will fallback to it's default behaviour
and use system dirs
- fix issue with bad tempdir (not existing/not createable/not writeable)
i.e nobody and ~/.ansible/tmp
- added tests for blockfile case
* Revert "Temporarily revert c119d54"
This reverts commit 5c614a59a6.
* changes based on PR feedback and changelog fragment
* changes based on the review
* Fix tmpdir when makedirs failed so we just use the system tmp
* Let missing remote_tmp fail
If remote_tmp is missing then there's something more basic wrong in the
communication from the controller to the module-side. It's better to
be alerted in this case than to silently ignore it.
jborean and I have independently checked what happens if the user sets
ansible_remote_tmp to empty string and !!null and both cases work fine.
(null is turned into a default value controller-side. empty string
triggers the warning because it is probably not a directory that the
become user is able to use).
* create module tmpdir based on remote_tmp
* Source remote_tmp from controller if possible
* Fixed sanity test and not use lambda
* Added expansion of env vars to the remote tmp
* Fixed sanity issues
* Added note around shell remote_tmp option
* Changed fallback tmp dir to ~/.ansible/tmp to make shell defaults
* Remove use of six.b as Python-2.6+ have byte literals.
* Make AnsibleModule a global object so we'll have access to it in all
the functions we're going to break this up into.
* Rework the parameters so things that are in file_common_args are used
from file_common_args or the reason for deviation is documented.
* Remove validate as a parameter: this should be taken care of by
removing it from params before the copy and template action plugin
invoke file.
* Rename diff_peek to _diff_peek as it is an internal parameter.
* add module_name execute_module call to assemble so that it is more greppable
* Allow subspec defaults to be processed when the parent argument is not supplied
* Allow this to be configurable via apply_defaults on the parent
* Document attributes of arguments in argument_spec
* Switch manageiq_connection to use apply_defaults
* add choices to api_version in argument_spec
* basic: allow one or more when param list having choices
* add unit tests
* optimize a bit
* re-add get_exception import
* a number of existing modules expect to be able to get it from basic.py
* allow shells to have per host options, remote_tmp
added language to shell
removed module lang setting from general as plugins have it now
use get to avoid bad powershell plugin
more resilient tmp discovery, fall back to `pwd`
add shell to docs
fixed options for when frags are only options
added shell set ops in t_e and fixed option frags
normalize tmp dir usag4e
- pass tmpdir/tmp/temp options as env var to commands, making it default for tempfile
- adjusted ansiballz tmpdir
- default local tempfile usage to the configured local tmp
- set env temp in action
add options to powershell
shift temporary to internal envvar/params
ensure tempdir is set if we pass var
ensure basic and url use expected tempdir
ensure localhost uses local tmp
give /var/tmp priority, less perms issues
more consistent tempfile mgmt for ansiballz
made async_dir configurable
better action handling, allow for finally rm tmp
fixed tmp issue and no more tempdir in ballz
hostvarize world readable and admin users
always set shell tempdir
added comment to discourage use of exception/flow control
* Mostly revert expand_user as it's not quite working.
This was an additional feature anyhow.
Kept the use of pwd as a fallback but moved it to a second ssh
connection. This is not optimal but getting that to work in a single
ssh connection was part of the problem holding this up.
(cherry picked from commit 395b714120522f15e4c90a346f5e8e8d79213aca)
* fixed script and other action plugins
ensure tmpdir deletion
allow for connections that don't support new options (legacy, 3rd party)
fixed tests
* basic.py: add mock to os.path.exists
* set_*_if_different: if check_mode enabled & file missing: set changed to True
Fixes#32676
Thanks to mscherer and Spredzy for the distributed triplet programming
session!
Shell is implemented via the command module. There was a special case
in mod_args to do that. Make shell into an action plugin to handle that
instead.
Also move the special case for the command nanny into a command module
action plugin. This is more appropriate as we then do not have to send
a parameter that is only for the command module to every single module.
* Deprecate check_invalid_arguments
Check_invalid_arguments is a piece of functionality from the early days
of Ansible that should not be used. We'll remove it in Ansible 2.9.
Deprecating it for now.
Split the one monolithic test for basic.py into several files
* Split test_basic.py along categories.
This is preliminary to get a handle on things. Eventually we may want
to further split it so each file is only testing a single function.
* Cleanup unused imports from splitting test_basic.py
* Port atomic_move test to pytest.
Working on getting rid of need to maintain procenv
* Split a test of symbolic_mode_to_octal to follow unittest best practices
Each test should only invoke the function under test once
* Port test_argument_spec to pytest.
* Fix suboptions failure
https://docs.python.org/2/library/stdtypes.html#str.split
str.split([sep[, maxsplit]])
If sep is given, consecutive delimiters are not grouped together and are deemed
to delimit empty strings.
>>> "85563 ----------------C-- /var/lib/libvirt/images".split(' ')[0:2]
['85563', '']
>>> "85563 ----------------C-- /var/lib/libvirt/images".split()[0:2]
['85563', '----------------C--']
* Deprecate Entity, EntityCollection and use subspec in network modules
* As per proposal https://github.com/ansible/proposals/issues/76
deprecate use of Entity, EntityCollection, ComplexDict, ComplexList
and use subspec instead.
* Refactor ios modules
* Refactor eos modules
* Refactor vyos modules
* Refactor nxos modules
* Refactor iosxr modules
* Add support for key in suboptions handling
* Fix CI issues
* jsonify inventory
* smarter import, dont pass kwargs where not needed
* added datetime
* Eventual plan for json utilities to migrate to common/json_utils when we split
basic.py no need to move jsonify to another file now as we'll do that later.
* json_dict_bytes_to_unicode and json_dict_unicode_to_bytes will also
change names and move to common/text.py at that time (not to json).
Their purpose is to recursively change the elements of a container
(dict, list, set, tuple) into text or bytes, not to json encode or
decode (they could be a generic precursor to that but are not limited
to that.)
* Reimplement the private _SetEncoder which changes sets and datetimes
into objects that are json serializable into a private function
instead. Functions are more flexible, less overhead, and simpler than
an object.
* Remove code that handled simplejson-1.5.x and earlier. Raise an error
if that's the case instead.
* We require python-2.6 or better which has the json module builtin to
the stdlib. So this is only an issue if the stdlib json has been
overridden by a third party module and the simplejson on the system
is 1.5.x or less. (1.5 was released on 2007-01-18)
* Remove uses of assert in production code
* Fix assertion
* Add code smell test for assertions, currently limited to lib/ansible
* Fix assertion
* Add docs for no-assert
* Remove new assert from enos
* Fix assert in module_utils.connection
