Now we accept IPv6 addresses _with port numbers_ only in the standard
[xxx]:NN notation (though bare IPv6 addresses may be given, as before,
and non-IPv6 addresses may also be placed in square brackets), and any
other host identifiers (IPv4/hostname/host pattern) as before, with an
optional :NN suffix.
The new code parses INI-format inventory files in a single pass using a
well-documented state machine that reports precise errors and eliminates
the duplications and inconsistencies and outright errors in the earlier
three-phase parsing code (e.g. three ways to skip comments). It is also
much easier now to follow what decisions are being taken on the basis of
the parsed data. The comments point out various potential improvements,
particularly in the area of consistent IPv6 handling.
On the ornate marble tombstone of the old code, the following
inscription is one last baffling memento from a bygone age:
- def _before_comment(self, msg):
- ''' what's the part of a string before a comment? '''
- msg = msg.replace("\#","**NOT_A_COMMENT**")
- msg = msg.split("#")[0]
- msg = msg.replace("**NOT_A_COMMENT**","#")
- return msg
This change is similar to https://github.com/ansible/ansible/pull/10465
It extends the logic there to also support none types. Right now if you have
a '!!null' in yaml, and that var gets passed around, it will get converted to
a string.
eg. defaults/main.yml
```
ENABLE_AWESOME_FEATURE: !!null # Yaml Null
OTHER_CONFIG:
secret1: "so_secret"
secret2: "even_more_secret"
CONFIG:
hostname: "some_hostname"
features:
awesame_feature: "{{ ENABLE_AWESOME_FEATURE}}"
secrets: "{{ OTHER_CONFIG }}"
```
If you output `CONFIG` to json or yaml, the feature flag would get represented in the output
as a string instead of as a null, but secrets would get represented as a dictionary. This is
a mis-match in behaviour where some "types" are retained and others are not. This change
should fix the issue.
I also updated the template test to test for this and made the changes to v2.
Added a changelog entry specifically for the change from empty string to null as the default.
Made the null representation configurable.
It still defaults to the python NoneType but can be overriden to be an emptystring by updating
the DEFAULT_NULL_REPRESENTATION config.
first off, we add an oddly slow basic test of 10k item inventory
Before:
```
Ran 229 tests in 13.214s
OK
real 0m13.403s
user 0m12.106s
sys 0m1.155s
```
After:
```
Ran 230 tests in 21.328s
OK
real 0m21.516s
user 0m20.099s
sys 0m1.275s
```
since that seems like a bit long for the test to add to runtime, lets profile
`python -m cProfile -s time ./bin/ansible all -i test/units/inventory_test_data/huge_range --list-hosts`

The top two lines are promising optimization targets
- populate Inventory's host cache more in _get_host, as we are looping
over all the groups anyways.
- eliminate duplicate check of whether we've already included a host
in the construction around __append_host_to_results we can infer
presence of a host in the results list implies the presence of its
name in the hostnames set, allowing us to only to the less expensive
of the two checks

* Speed up serialization of hostvars by simply using the internal
dictionary used for cached lookups
* Use blocking gets/puts on queues instead of spin locking
* Merge sequential implicitly created blocks
* now it uses -n to get immediate error if no password is supplied and one is needed,
this should fix the issue with sudo hanging waiting for input.
* made -k configurable, this can break changing become_users in play if left out,
but opens up the possiblity of OTP support.
This function takes a string like 'foo:bar[1:2]:baz[x:y]-quux' and
returns a list of patterns ['foo', 'bar[1:2]', 'baz[x:y]-quux'], i.e.
splits the string on colons that are not part of a range specification.
get_hosts → used externally, not changed
_get_hosts → _evaluate_patterns (takes a list, evaluates ! and &)
__get_hosts → _match_one_pattern (takes one pattern only, ignores !&)

This was used earlier to implement serial, but that's now done using
restrict_to_hosts() (whose docstring is also suitably adjusted here)
and there are no more callers.
* A commen dict of keys has been defined, which we look in results returned from the API.
* self.returns dict can be use in subclass to extend this dict.
* Optionally the key name can be replaced with a new key name, often used to make the return keys identical to the arguments passed.
* Use new style class
Since we explicitly set convert_bare=False in the template lookup
code, but still want individual looks that call listify directly to
convert bare variables if needed.
This is a slightly different fix than we originally committed, but fixes
the problem in a less invasive way (and I believe it's generally better
that we don't deal with relative paths internally past this point)
Fixes#11789
* Better comments
* Reorganize code so related settings are close to each other
* Add ::1 to the "localhost" patterns we look for
* Make the dest_port parameter override the ansible_ssh_port setting
* Fix dest_port (wasn't being set)
* more complete detection of delegate_to
* Fix set_remote_user (wasn't being looked for in parameters)
* Instead of removing mode here, have the ansible module accept it
(better documents the parameters doing it htat way)
Fixes bugs related to creating Templar() objects on the fly, where
the shared loader objects (serialized to TaskExecutor) aren't used
so information loaded into plugin loaders after forking is lost.
Fixes#11815
We can unconditionally wrap remote_addr in square brackets for scp and
sftp (both of which require them for IPv6 addresses), but not wrap them
at all for ssh (which doesn't accept them). This way, we don't have to
detect and treat IPv6 addresses specially. This works for hostnames,
IPv4 addresses, and IPv6 addresses.
The earlier code seemed to intend to wrap all IPv6 addresses in square
brackets, which would have broken ssh, but it actually made no attempt
to detect IPv6 addresses at all (so it broke only with IPv6 addresses
for scp and sftp).

In stable-1.9, the prompt string is passed to raw_input(), which prints
it without an extra \n. Here we're just print()ing it, so the \n would
be doubled.

- Add support for inserting module args into PowerShell modules. Fixes#11661.
- Support Windows paths containing spaces. Applies changes from #10727 to v2. Fixes#9999. Should also fixansible/ansible-modules-core#944 and ansible/ansible-modules-core#1007.
- Change how execution policy is set for running remote scripts. Applies changes from #11092 to v2. Also fixesansible/ansible-modules-core#1776.
- Use codepage 65001 (UTF-8) for WinRM connection instead of default (CP437), convert command to UTF-8 and results from UTF-8. Replaces changes from #10024. Fixes#11198.
- Close WinRM connection when task completes.
- Use win_stat, win_file and win_copy modules instead of stat, file and copy when called from within other action plugins (only when using WinRM+PowerShell).
- Unquote Windows path arguments before passing to win_stat, win_file, win_copy and slurp modules (only when using WinRM/PowerShell).
- Check for win_ping module to determine if core modules are missing (only when using WinRM/PowerShell).
- Add stdout_lines to result from running low level commands (so stdout_lines is available when using raw/script).
- Update copy action plugin to use shell functions for joining paths and checking for trailing slash.
- Update fetch action plugin to unquote source path when using Windows paths.
- Add win_copy and win_template action plugins that inherit from copy and template.
- Support running .bat and .cmd scripts using default system encoding instead of UTF-8.
- Always send PowerShell commands as base64-encoded blobs to allow for running simple PowerShell commands via raw.
- Support running modules on Windows with interpreters other than PowerShell.
- Update integration tests to support above changes and test unicode fixes.
- Add test for win_user error from ansible/ansible-modules-core#1241 (fixed by ansible/ansible-modules-core#1774).
- Add test for additional win_stat output values (implemented by ansible/ansible-modules-core#1473).
- Add test for OS architecture and name from setup.ps1 (implemented by ansible/ansible-modules-core#1100).
All WinRM integration tests pass for me with these changes.
