This patch adds the port argument as a valid parameter to the f5_spec.
This argument is supported in bigsuds version 1.0.4 and greater, so
this patch uses the __version__ variable of the bigsuds module to
determine when the port value should be honored by the module.
By default the `Shell` class disables ssh agents. The `junos_netconf`
module uses this class, but doesn't re-enable agents.
Here it's explicitly enabled again, so an ssh agent can be used to
connect to and configure Junos devices.
* Don't filter hosts remaining based on their failed state. Instead rely
on the PlayIterator to return None/ITERATING_COMPLETE when the host is
failed.
* In the free strategy, make sure we wait outside the host loop for all
pending results to be processed.
* Use the internal _set_failed_state() instead of manually setting things
when a failed child state is hit
Fixes#15623
In `lib/ansible/executor/play_iterator.py`, ansible sets a host's
`_gathered_facts` property to `True` without checking to see if there
are any tasks to be executed. In the event that the entire play is
skipped, `_gathered_facts` will be `True` even though the `setup`
module was never run.
This patch modifies the logic to only set `_gathered_facts` to `True`
when there are tasks to execute.
Closes#15744.
This changeset addresses the issue reported here:
ansible/ansible-modules-core#1765
The yum module (at least) includes its task results as strings, rather than
dicts, and the code this changeset replaces assumed that in that instance the
task was skipped. The updated behaviour assumes that the task has been
skipped only if:
* results exist, and
* all results are dicts that include a truthy skipped value
Issue #15633 observes that a meta: inventory_refresh task causes the playbook
to exit. An inventory refresh flushes all caches and rebuilds all host
objects, assigning new UUIDs to each. These new host UUIDs currently fail to
match those on host objects stored for restrictions in the inventory, causing
the playbook to exit for having no hosts to run further tasks against.
This changeset attempts to address this issue by storing host restrictions
by name, and comparing inventory host names against these names when applying
restrictions in get_hosts.

It wasn't doing anything that a literal couldn't do and used
unicode_escape which only understands latin1 (The author of the code
seems to have thought it took an encoding argument but it looks like
that was silently ignored.)
This was reinitialized every time we forked before so we weren't sharing

Ensure that initial setup in creating the key directory for ansible
accelerate mode keys, and generation/storage of the key for a
particular host are completed in a multiprocess safe manner.
Creating directories/files and then assigning permissions and contents
to them means that paths may exist and satisfy the os.path.exists()
method in python for other processes before they are usable.
Use a combination of locking around operations with use of unique named
files and an OS file system move to ensure that the conditions of
checking whether a file or directory exists, where it is potentially
created by another thread, will only succeed when the file has both the
correct contents and permissions.
Fixes#13850
Previously we were first checking the fail/run state of the child
state for tasks/rescue/always portions of the block. Instead we are now
always recursively iterating over the child state and then evaluating
whether the child state is failed or complete before changing the failed/
run state within the current block.
Fixes#14324
This update will attempt to guess the file format based on the template
extension if the format argument isnt set. It will also set the commit
comment to the task name if the comment isnt' explicitly defined.
This adds a check to validate the arugment for config_format kwarg in
get_config. If the specified format is not a valid option, the shared
module will call fail_json
Netconf support is provided using the junos-eznc library and the shared
module depends on junos-eznc to be installed on the local Ansible host. This
commit also adds changes to the netcfg library to handle receiving messages
over netconf.
To use netconf, specify transport=netconf for junos module. Be sure that
netconf has been enabled on the remote device.
Which we're use on a case-by-case basis if we find people were actually
using comma-separated strings for list values outside of hosts. Support
for doing so is now deprecated and users should instead use the full
YAML syntax for lists of values.
Fixes#15291
* Don't rely on username to check for root privileges
The SSH username isn't a reliable way to check if we've got root privileges on
the remote system (think "toor" on FreeBSD). Because of this check, Ansible
previously tried to use the fallback solutions for granting file access (ACLs,
world-readable files) even on systems where it had root privileges when the
remote username didn't match the literal string "root".
Instead of running checks on the username, just try using `chmod` in any case
and fall back to the previous "non-root" solution when that fails.
* Fail if we are root and changing ownership failed
Since this code is security sensitive we document exactly the expected
permissions of the temporary files once this function has run. That way
if a flaw is found in one end-result we know more precisely what scenarios
are affected and which are not.
Instead of using the old OpenSwitch runconfig, we'll use
Mir's new ops.dc declarative config for the DC interaction
with OpenSwitch. This gives us the clearer separation between
ansible and the OpenSwitch, as well as the performance
improvement done inside the ops.dc module itself.
Squashed the original Mir's change into single commit.

Updated python module wrapper explode method to drop 'args' file next to module.
Both execute() and excommunicate() debug methods now pass the module args via file to enable debuggers that are picky about stdin.
Updated unit tests to use a context manager for masking/restoring default streams and argv.
If add_host is performed with hostname existing in inventory, but
not yet accessed and put in inventory cache, additional host with
same hostname and different uuid is created, causing patterns to
misbehave.
- search entity by path
- search vm based on folder
- search for a vm based on given id ( uuid/name/dns_name/ip/inventory_path)
- search for a cluster by name, in a given datacenter (optionally)
- search for objects of a given type in a folder
Note: instance uuid is unique to a VM
The first filter is regex_search which adds the ability to do a regex
search on a fact. The filter supports returning either all capture groups
or a set of capture groups (either by index or named).
Example usage of regex_search filter
debug: msg="{{ out.stdout[0] | regex_search('image version. (?P<test>\d+).(\d+)', '\\g<test>', '\\2' ) }}"
The second filter is regex_findall with adds the capability to do a
regex findall on a fact or variable and return all occurances of a pattern.
debug: msg="{{ out.stdout[0] | regex_findall('vlan (\d+)' }}"
The filter supports two addtional keyword arguments, ignorecase=[true, false]
and multiline=[true, false]
rm _del_ as it might leak memory

- get_real_file will decrypt vault encrypted files and return a path to
a temporary file.
- cleanup_real_file will remove a temporary file created previously with
get_real_file
Ansible when there was a percentage that was calculated to be less than
1.0 would run all hosts as the value for a rolling update.
The error is due to the fact that Python will round a
float that is under 1.0 to 0, which will trigger the case of
0 hosts. The 0 host case tells ansible to run all hosts.
The fix will see if the percentage calculation after int
conversion is 0 and will else to 1 host.
This makes our recursive, ast.parse performance measures as fast as
pre-ziploader baseline.
Since this unittest isn't testing that the returned module data is
correct we don't need to worry about os.rename not having any module
data. Should devise a separate test for the module and caching code
Since 2.0 made all includes dynamic, it is now possible to create and
include a file in the course of executing a playbook. However, with the
introduction of implicit static includes this can cause problems if an
include is thought to be static but does not yet exist. For now, we're
handling missing implicit static includes as a potential dynamic include
but also adding a deprecation message to show includes like this will
need to be marked as `static: no` in the future.
Fixes#15342
Due to an apparent race condition while using pty's on a heavily loaded
system, rarely a request to create a temp directory returns an empty
string rather than the newly created path, causing an error. Disabling
forced pty's appears to resolve the issue, so this patch modifies the
mkdtemp remote call not use -tt as we're not escalating privileges and
thus no pty is required.

Some debuggers are easier to work with when we do everything in a single
process. This debug option caters to that at the expense of being
different from what Ansible will actually do to invoke a module.
When we document this we should be clear that this shouldn't be used for
general purpose debugging and that some modules may show strange
"errors" when used with this. Those won't be considered real bugs as
it's not how ansible really invokes the modules.
action plugins will now skip _fixup_perms for Powershell. We'll have to come up with another way to do this at some point, but it's not necessary yet since we don't support become on Windows. Also added NotImplementedError throws to chmod/chown/set_facl operations on Powershell (instead of returning '') in case anyone tries to use them in the future.
fixes#15312
* Run the module as a script from the wrapper instead of executing in the same process.
Fixes cornercases where the module could potentially be executed twice
if we import and then run the main() function without calling sys.exit()
somewhere.
Also fixes problem with concurrent.futures() hanging. Not sure
precisely how this is being triggered but it is related to invoking the
main() function outside of an if __name__ == '__main__' conditional.
* Fix for python-2.6
This reverts commit 1ffadbcc80.
Some modules seem to have path listed for things that are "commands" --
something that may be a path to a command or a bare command that should
be looked up in PATH. With this change, if they were formerly looked up
inPATH they are now being made into an absolute path in the cwd.
Reverting this until we can think more about whether to do this and
change those modules to not use path for those parameters.
* Ziploader proof of concept (jimi-c)
* Cleanups to proof of concept ziploader branch:
* python3 compatible base64 encoding
* zipfile compression (still need to enable toggling this off for
systems without zlib support in python)
* Allow non-wildcard imports (still need to make this recusrsive so that
we can have module_utils code that imports other module_utils code.)
* Better tracebacks: module filename is kept and module_utils directory
is kept so that tracebacks show the real filenames that the errors
appear in.
* Make sure we import modules that are used into the module_utils files that they are used in.
* Set ansible version in a more pythonic way for ziploader than we were doing in module replacer
* Make it possible to set the module compression as an inventory var
This may be necessary on systems where python has been compiled without
zlib compression.
* Refactoring of module_common code:
* module replacer only replaces values that make sense for that type of
file (example: don't attempt to replace python imports if we're in
a powershell module).
* Implement configurable shebang support for ziploader wrapper
* Implement client-side constants (for SELINUX_SPECIAL_FS and SYSLOG)
via environment variable.
* Remove strip_comments param as we're never going to use it (ruins line
numbering)
* Don't repeat ourselves about detecting REPLACER
* Add an easy way to debug
* Port test-module to the ziploader-aware modify_module()
* strip comments and blank lines from the wrapper so we send less over the wire.
* Comments cleanup
* Remember to output write the module line itself in powershell modules
* for line in lines strips the newlines so we have to add them back in

The network config and template modules share a set of common functions that

I was surprised to see complete file content in the (JSON) task output when
in diff-mode. Since we see the diff anyhow, there's no need to send everything
on screen.
`ansible_failed_task`:
Contains the task data, essentially a serialized view of the Task() object.
`ansible_failed_result`:
Contains the result of the task failure, which is identical in function
to registering the result. Doing so automatically like this saves the user
from having to register every result in a block and then trying to figure
out which result had the failure
Similar to the way try/except/finally work, these variables will not be
available in the `always` portion of a block unless there is a corresponding
`rescue` first.
Fixes#12341
Prompt search logic is now localized to the ios shared module instead
of using the common regexps in the shell module. This resolves a number
of problems with ios modules functioning properly
The changes to chown/chmod were broken on Mac (-R was being appended to the end of the command- OSX requires it before the file list).
A number of base action remote setup commands were also blindly proceeding without checking for success. Added error raises for unrecoverable failure cases.
Previously, split_args() was not taking print/block/comment depth into account
when splitting things, meaning that if there was a quote character inside an
un-quoted variable (ie. {{ foo | some_filter(' ') }}), it was incorrectly
splitting on the quotes instead of continuing to append to the previous param.
Fixes#13630
A few of the docs fragments have the available choices for some params
defined as "BOOLEANS". Because choices accepts a list, it treats
"BOOLEANS" as an iterable and then generates a list composed of each
letter.
Instead, define the available choices as a list of `['yes', 'no']`,
as is common in most other modules.
If we're not delegating then we change _connection into a local
connection midway through the file but we don't change
_play_context.connection (no need to alter that). When we later check
it in process_remote() we need to know the actual connection, not the
connection that we thought we were going to use at the start of run().
So we have to use _connection.transport in process_remote(). The rest
of the places could use either one (because we have not yet changed to
a local connection) but we go ahead and switch those to
_connection.transport as well to avoid confusion in the future.

* Can be configured in the ansible.cfg for tasks/handlers individually
* If an included filename contains no vars or loops, it will be expanded

* class_only was a keyword arg of get() and all() that was mistakenly
passed on to Plugins. Be sure to strip it from the keyword args
before instantiating Plugins. (Reworked API probably should either
not instantiate Plugins or take the args for the Plugin as a separate
list and a dict.)
* Checking required base_classes was only done in get() and only if
class_only was False (ie: that Plugin was instantiated). This meant
that different plugins could be found depending on whether the call
was to .get() or to all() and whether it was for classes or instances.
Fixed so that required base_classes are always checked.
Modules shouldn't need to import boto.ec2.
The check was to test if profile_name was supported by boto.
Two years after the introduction of the support, we will now
assume that if people are passing `profile`, they are using
a version of boto that supports it (this requirement is
already documented in the aws documentation fragment)
Also remove even older version check for `validate_certs`
Fixes#1901
* Make role param resolution follow the role dependency chain, rather
than using all roles within the play
* Also move params to be merged in after role vars in general, to match

above possible without trampling on previously merged vars

On none-Linux systems `get_distribution()` returns `None`, which fails in `fetch_url`, because the return value of `get_distribution()` is not checked before calling `lower()` on the result.
This commit address a number of minor updates the nxos shared module
* connect() is now lazy loaded
* parse inner output messages when errored
* code syntax cleanup
* Make documentation examples into code blocks
* Make code to call the subsets more general.

* Use a passed in modules parameter rather than global modules. This is needed for ziploader
* Remove unneeded __init__()
* Remove uneeded multiple inheritance from a base class
* gather_facts is now a list type
This commit adds a new feature to allow implementations of shell to
specify the command prompt regexp to be used. It allows adds a new
kwarg at instantiation to kick the remote device with a carriage return.
By default the kickstart flag is true but can be disabled by passing
kickstart=False.
This commit address to issues in the eos shard module. The first one
is a bug fix for returning the running config when the transport is eapi.
The shared module will now return config text instead of an object. The
second is a optimization that delays when the eos module connects to the
remote devices. This provies a performance enhancement when using
ssh since the module doesn't default to connecting immediately
Just including the `ssl` key in the config for MySQLdb.connect, causes it to check for the existence of SSL support. This patch only adds the key if one of the ssl configuration options is included.
On some switches, starting an SSH connection and immediately calling
recv() will result in a connection timeout. The switch requires some
input on the channel before it provides any prompt.
As such, this patch sends an empty command immediately upon connection,
triggering the switch to send a prompt which the shell can then
interpret.

* Cleaned up logic in PlayIterator

This commit fixes two bugs in the openswitch shared module. The first
bug was a wrong argument type for the use_ssl argument. It was set

This commit changes the key the ops_template will search for in order
to backup the current configuration to local disk on the Ansible control
host. This change was made to make ops_template consistent with the
other network template modules.
Note that this will break if we deal with non-utf8 paths. Fixing this
way because converting everythig to byte strings instead is a very
invasive task so it should be done as a specific feature to provide
support for non-utf8 paths at some point in the future (if needed).
This is the same fix we applied to v1.9 in PR #14565, however it does not fix#14678 completely !
The dictionaries are not being merged as tey are on v1.9.
The use of realpath means when following symlinks the actual path is

The find_mount_point function does not resolve the mount point of paths with a soft-link correctly and returns the wrong mount-point.
I have mounted an NFS filesystem on /nfs-mount. This directory contains a directory called "directory". I also created a soft-link to this last directory: /soft-link-to-directory -> /nfs-mount/directory. I created the following task to copy a file into /soft-link-to-directory:
- name: copy file to nfs-mount
copy:
src: "file"
dest: "/soft-link-to-directory/file"
This throws an exception:
invalid selinux context: [Errno 95] Operation not supported
This is caused by the find_mount_point function to return '/' as the mount point for '/soft-link-to-directory/file'. This should have been /nfs-mount. Because the find_mount_point returns the wrong mount-point, the is_special_selinux_path function does not recognise the file is on an NFS mount and tries to set the default SELinux context (system_u:object_r:default_t:s0), which fails. The context should have been: system_u:object_r:nfs_t:s0
