Caveats:
* requiretty must be disabled in the sudoers config
* asking for a password doesn't work yet, so any sudoers users must
be configured with NOPASSWD
* if not starting the daemon as root, the user running the daemon
must have sudoers entries to allow them to run the command as the
target sudo_user
Still needs:
* chunked file transfer/receive
* should probably move all send/recv operations to separate
functions to reduce code duplication
* initial connection setup over ssh? or do we handle that in runner?
This is based somewhat loosely on how Keyczar does things. Their
implementation does things in a much more generic way to allow for more
variance in how the cipher is created, but since we're only using one
key type most of our values are hard-coded. They also add a header to
their messages, which I am not doing (don't see the need for it
currently).

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.
For some reason, ssh seems to ask for password even when
PasswordAuthentication is set to no, adding PreferredAuthentications
with the 2 options removed do the trick.
Tests `test_playbook_undefined_varsX_fail` check if ansible detects
undefined variables when `error_on_undefined_vars` is enabled. These
tests fail without "Improve behavior with error_on_undefined_vars
enabled" patch.
Tests `test_playbook_undefined_varsX_ignore` check if ansible ignores
undefined variables when `error_on_undefined_vars` is disabled.
Also modify PlayBook._run_task_internal() so error_on_undefined_vars is
testable.
Pass fail_on_undefined flag to recursive calls to `template` function,
so more undefined variables are detected.
Works only for Jinja style variables. Undefined legacy variables are
never detected.
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.
For link-local addresses, it is sometimes necessary to append the
interface to use for the ipv6 address. This patch extends the ipv6
regex to allow for '%ifnameX' at the end.
See https://bugzilla.redhat.com/show_bug.cgi?id=136852 for more info
Due to various inconsistencies of ssh and sftp regarding ipv6 and
ipv4 handling, some special arguments must be passed, and the
ipv6 must be passed in a specific format.
testing with a ipv6 :
ansible -u misc -i '[2002::c23e]:22,' '*' -m ping
fail due to parsing of ':' as a separator of port/ip with ipv4.
This commit add support for properly parsing 2002::c23 and the
bracket notation [2002::ce]:2222
The block that added the original list of roles was indented too far,
and was only being reached if a role had dependencies. This resulted
in roles without dependencies from being added to the list of roles.
Credit goes to looped for reporting and diagnosing the issue.
Fixes#3686
Dependencies are enabled by adding a new directory/file named
meta/main.yml to the role. The format of the dependencies are:
dependencies:
- { role: foo, x: 1, y: 2 }
- { role: bar, x: 3, y: 4 }
...
Dependencies inherit variables as they are seen at the time of the
dependency inclusion. For example, if foo(x=1, y=2) has a dependency
on bar(x=3,z=4), then bar will have variables (x=3,y=2,z=4).
Different roles can have dependencies on the same role, and this
variable inheritence allows for the reuse of generic roles quite easily.
For example:
Role 'car' has the following dependencies:
dependencies:
- { role: wheel, n: 1 }
- { role: wheel, n: 2 }
- { role: wheel, n: 3 }
- { role: wheel, n: 4 }
Role 'wheel' has the following dependencies:
dependencies:
- { role: tire }
- { role: brake }
The role 'car' is then used as follows:
- { role: car, type: honda }
And tasks/main.yml in each role simply contains the following:
- name: {{ type }} whatever {{ n }}
command: echo ''
TASK: [honda tire 1]
TASK: [honda brake 1]
TASK: [honda wheel 1]
TASK: [honda tire 2]
TASK: [honda brake 2]
TASK: [honda wheel 2]
TASK: [honda tire 3]
TASK: [honda brake 3]
TASK: [honda wheel 3]
TASK: [honda tire 4]
TASK: [honda brake 4]
TASK: [honda wheel 4]
TASK: [I'm a honda] <- (this is in roles/car/tasks/main.yml)
by ensuring all basedirs, plugin paths and extra
paths are handled as absolute paths and are checked
to not add any doubles.
This fixes the corner case where e.g. the user has
an additional plugin path configured to a dir
relative to his playbooks or inventory location,
which also matches the _plugin subdir relative to
one of the basedirs in the play.
For most plugins this doesn't show as an obvious issue
except for callback_plugins, which might fire more
than once. Other plugins (inventory and template
plugins) might unnecessarily be ran twice.
e.g. ansible.cfg has
callback_plugins = ./plays/callback_plugins
and plays/ contains a playbook file:
.
├── ansible.cfg
├── inventory
└── plays
├── callback_plugins
│ └── timestamp.py
└── site.yml
modified: lib/ansible/utils/plugins.py
Previous patch was reverted due to the fact that there was an issue
with the results not always being a dictionary (they're sometimes
a unicode string, ie. when the with_items is used with yum). This
minor change corrects that by checking for a dict object.
to ensure consistent behavior, hosts should look like this:
hosts: webservers:&boston:!rack42
So when applying the host selectors, run those without the "&" first,
then the &s, then the !s.
Closes#3500
If SELinux is enabled and mcstrans is running, daemons are restarted on each
run. After further debugging, it turn out that ansible compare the untranslated
level 's0' with the translated level 'SystemLow' due to mcstrans being running,
which trigger a handler since this is considered as a change.
and the _meta hash contains a "hostvars", don't call --host hostname for any elements
and just serve them directly for performance enhancements with the external inventory
script and a large number of hosts.
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.
Treat errno 13 (permission denied) as one of the special cases in
atomic_move.
This type of error can occur because of sudo'ing to non-root user.
Fixes#3705
Since ansible 1.2, it became possible to place a host_vars
directory in the same directory as a playbook, making it possible
to keep host_vars local to that playbook there. However, due to
python's os.path.dirname, a action such as:
$ ansible-playbook pb.yml
..would not pick up the host_vars as os.path.dirname("pb.yml")
returns "", unlike the unix command dirname that would return
".". Substituting "pb.yml" on the command line with "./pb.yml"
would do the trick, but is not always intuitive. This patch
solves the problem until python solves issue18547 [1].

-c ssh is preferred in most cases if you have ControlPersist available, otherwise if you are comfortable you
can turn off recording while leaving host key checking on, etc.
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.
* Moved the --list-hosts option that is common to both `ansible` and
`ansible-playbook` into utils/__init__.py (corrects a FIXME)
* Wrote new help text for the --list-hosts option that makes sense
for both of the commands that it applies to
* Changed the usage argument in `ansible-playbook` so that it is
setup in the base_parser method the same way that it is in
the `ansible` executable
* Updated the help text for several options to correct typos,
clarify meaning, improve readability, or fix grammatical errors.
In the case of `ansible-pull`, I changed the help text so that
it adheres to the same standards as the other executables.
The action doesn't actually change anything on a system, so setting
the status to changed is wrong. add_host is much like set_fact in that
regard.
Since changed is False by default, there is no need to explicity set
it, so just create an empty dict for result and add to it from there.
ansible.constants was calling expanduser (by way of shell_expand_path)
on the entire configured value for the library and *_plugins
configuration values, but these values have always been interpreted as
multiple directories separated by os.pathsep. Thus, if you supplied
multiple directories for one of these values, typically only the first
(at least on *nix) would have e.g. "~" expanded to HOME.
Now PluginLoader does expansion on each individual path in each of
these variables.
A host pattern of the form '!foo' by itself does not work, but
'all:!foo' does. If the first pattern is a negation, this commit
automatically prepends 'all'.
