The 'always_run' task clause allows one to execute a task even in
check mode.
While here implement Runner.noop_on_check() to check if a runner
really should execute its task, with respect to check mode option
and 'always_run' clause.
Also add the optional 'jinja2' argument to check_conditional() :
it allows to give this function a jinja2 expression without exposing
the 'jinja2_compare' implementation mechanism.
Previously, hostvars would only expose a keys() list of hosts that had
been seen yet- however you could explicitly access the host if you knew
the name, and get the content that way. This precludes template code
from being able to safely access information about other hosts if any
limiters/tags were in use.
Additionally, the object was inconsistent for hostvars['myhost'] access
and [x[1] for x in hostvars.items() if x[0] == 'myhost'] access; this is
due to the original derivation from the dict object. .items() would be
handled by dict.items(), using the passed in setup_cache values without
using the actual lookup content.
This patch rebases the class implementation to a py2.6 dictmixin, fixing
those issues and restoring behaviour to match what the docs claim.
Added support of an optional init method for action modules like rsync that need to alter the connection and other inject data before it's established.
Use case: e.g. dual homed hosts on production en management network
The inventory_hostname is the regular host name and matches the
dns name on the production network; ansible connects to the host
through a management network; the dns name on the management network
is standardized and equals ${inventory_hostname}-mgt.mynetwork.com
Now this can be configured as the default in group_vars/all:
ansible_ssh_host: {{ inventory_hostname + '-mgt.mynetwork.com' }}
str() throws an UnicodeEncodeError for code points that cannot be
represented in 7-bit ASCII. This makes it impossible to use any
non-ASCII characters in module arguments. Using encode('utf-8')
gives the desired result.

Add fail_on_undefined flag
Add a fail_on_undefined flag to the template and template_from_string methods.
If this flag is true, then re-raise the ninja2.excpetions.UndefinedError instead of

Optionally fail task on undefined variables
This patch introduces a new configuration option called
error_on_undefined_vars, which defaults to false.
If this option is set to true, then a task which has unevaluated
variables in its arguments will fail instead of running. Output looks
like this:
TASK: [set rabbitmq password] *************************************************
fatal: [10.20.0.7] => Undefined variables: rabbitmq_user, rabbitmq_password
hardcoded lists in ansible code, just add WITH_ITEMS_USES_LIST in a
comment anywhere, and of course, support recieving params as list.

Previous commit c3659741 expanded sudo_user during task construction,
but this is too early as it does not pick up variables set during
the play.
This commit moves sudo_user expansion to the runner after variables
have been merged.
Previously setting force=no caused copy to subversively
fail when target did not exist on remote host.
Caused by Runner._remote_md5 returning 1
when files don't exist, rather than 0.
The old test used syntax that appeared to be bash-specific and did not
work on platforms where /bin/sh did not point to bash. See issue #2742
where copy to solaris hosts failed with the error:
output: {'stdout': '', 'stderr': '/bin/sh: test: argument expected\n',
'rc': 1}
The copy action accepts force=no, which tells it not to replace an
existing file even if it differs from the source. The copy action
plug-in wasn't respecting this option when operated in check mode, so it
would report that changes are necessary in check mode even though copy
would make no changes when run normally.
Runner._remote_md5 was changed to make the logic for setting rc perhaps
a little more clear, and to make sure that rc=0 when the file does not
exist.
Use DEFAULT_EXECUTABLE when no executable is passed to
_low_level_command_exec
Works as a standard constant - can be overridden in all the normal ways
and defaults to /bin/sh
Motiviation is for a user that only has /bin/bash in /etc/sudoers
If it is a directory, change the destination path by appending the
basename of the source file, like is done if the destination ends with a
/, and try to get the MD5 of the new path.
Instead of having to remember when to use which one, rename template_ds
to template and move the last bit of code from template to varReplace
(which gets used for all string replacements, in the end).
This means that you can template any data type without worrying about
whether it's a string or not, and the right thing will happen.
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.
This ensures we don't litter remote systems with temporary directories
that don't get cleaned up, as well as speeds things up from not having
to touch every node.
Add constant DEFAULT_MODULE_LANG that defaults to C. Can be set via
environment variable ANSIBLE_MODULE_LANG or configuration variable
module_lang. Updated test-module to have same behavior.
As reported on the mailinglist, the user received a ValueError when the port number was not templated (fixed in #1649) and therefore it was not an integer. This change will catch the exception and provide a proper error so it is more clear.
Update constants.py so that one can specify environmental variable
ANSIBLE_SYSLOG_FACILITY or syslog_facility in ansible.cfg to define
the syslog facility to use. Alternatively, you can specify
ansible_syslog_facility in inventory. Runner now replaces
the syslog facility in the openlog() call with the default or
the injected variables ansible_syslog_facility.
This also updates hacking/test-module to behave similarly.
If you sudo to a non-root user, you get a permission denied error.
Here's an example:
$ ansible myserver.example.com -m postgresql_db -a "db=mydatabase" -u ubuntu -s -U postgres
myserver.example.com | FAILED >> {
"failed": true,
"msg": "chmod: changing permissions of `/tmp/ansible-
1351092257.96-157699143369671/postgresql_db': Operation not
permitted\n/usr/bin/python: can't open file '/tmp/ansible-
1351092257.96-157699143369671/postgresql_db': [Errno 13]
Permission denied\n",
"parsed": false
}
The problem is that ansible is doing the chmod as the sudo user
when it should be doing it as the remote user.
Automatic quoting of variables in only_if breaks existing playbooks
where entire statements are put in a variable, and other cases. See
issue #1120 for details.
Sometimes you may want to allow variables through host_vars or inventory, but prompt for a value if it is not set or if the value does not conform to something specific. This option allows you to specify when you want to offer a prompt.
This patch also moves check_conditional to utils, and adds an is_unset() function which is nicer to read:
only_if: "not is_set('${var}')"
vs
only_if: "is_unset('${var}')"
Paramiko does not allow Unicode strings as parameters, so encode
the command to UTF-8.
Test case:
ansible localhost -m raw -a 'echo ą'
(also tested on local and ssh transports without problems)
