Hash variables are currently overriden if they are redefined. This
doesn't let the user refine hash entries or overriding selected keys,
which can, for some, be a desirable feature.
This patch let the user force hash merging by setting the
hash_behaviour value to "merge" (without the quotes) in ansible.cfg
However, by default, ansible behaves like it always did and if any value
besides "merge" is used ("replace" is suggested in the example ansible.cfg
file), it will also behave as always.
PluginLoader.add_directory() can receive None from, for example,
Inventory.add_directory(self.basedir()) if host_list is a custom list.
None has no reasonable interpretation other than ignore it.
Adds -i to make_sudo_cmd so target user's environment gets loaded when configurationslike this are used :
- hosts: ubuntu
name: Install ruby for the configured ruby user
sudo: True
sudo_user: rubyuser
# should be ${ruby_user}, but can't for now because of #1665
tasks:
- name: Gets current ruby version
action: shell rbenv version
register: ruby_current_version
* Rename fail_on_rc_non_zero to check_rc, much more succinct.
* Simplify method defintion
* Fix command module and drop shell=shell option; whether to use
shell is determined by if args is a list.
This adds a helper method that modules can call to execute a command via
subproces. It takes two arguments: the command to run and
keyword options that control how the process is executed. Supported
options are: fail_on_rc_non_zero, close_fds, and executable.
fail_on_rc_non_zero will call fail_json if the command fails. If
args is a list, the command will be run with shell=False; otherwise, if
a string, it will be run with shell=True. Otherwise, run_command() returns
the returncode, stdout, and stderr.
For compatibility with older releases as well as avoiding things like
action: raw executable= show status
to communicate with devices that don't have sh.
This commit extends the 'when_' conditions to failed and changed
json results
Additionally it makes when_{set,unset,failed,changed,int,str,flt}
behave more similiarily in that they all except and/or/not logic
Two problems here
* unchecked exception handling and erroneous assumption as to why
an exception might fire
* although the file module expands the path, when using file_args
the unexpanded path is passed.
Expected result: ~/path/to/file should work fine
Actual result: exception is because it doesn't find file with a message
about not being able to get the selinux context
Added two additional template variables
* template_fullpath - absolute path to the template
* template_run_date - date that the template was rendered
Documented these additional variables in the module documentation
Path might have to be expanded on some operations. It seems that path
containing '~' are not.
Using os.path.expanduser in appropriate places solves the problem, but
this might be required in many other places.
It seems that os.path.basename(__file__) can return a unicode
string. In this case syslog.openlog fails. Forcing the result
to a string causes the resulting error to go away.
Since we use 'raw' heavily on equipment where 'command' and 'shell' are not (yet) working (and python may need to be installed first using raw) these improvements are necessary in order to write more complex scripts (with return code handling and separated stdout/stderr).
This change includes the following changes:
- exec_command() now returns the return code of the command
- _low_level_exec_command() now returns a dict, including 'rc', 'stdout' and 'stderr'
- all users of the above interfaces have been improved to make use of the above changes
- all connection plugins have been modified to return rc and stderr
- fix the newline problem (stdout and stderr would have excess newlines)
In a future commit I intend to add assertions or error handling code to verify the return code in those places where it wasn't done. Since only the output was available, the return code was ignored, even though we expect them to be 0.
