With cb80286a4a, the helper function
stringify_ansible_playbook_command was also applied on the
`raw_arguments` content, which is not wanted. Given that users have used
the `raw_arguments` option as a workaround to avoid the bug GH-6726,
this new change ensure that any `--extra-vars` option passed as a raw
argument won't be additonally enquoted by the ansible_local
provisioner.
This change also improves the ansible remote provisioner verbose output,
but has no impact on its behaviour, which was already correct.
Note that this refactoring introduces some code duplications that are not
very elegant (see ansible_playbook_command_for_shell_execution in
host.rb and execute_ansible_playbook_from_host in base.rb). I hope we
can find a better implementation later, but it is good enough for now
since all these parts are covered by corresponding unit tests (the
`ansible_local` stuff being tested via the verbose output of the ansible
remote provisioner).
Before this minor change, the '--limit' and '--start-at-task'
ansible-playbook command line arguments were enclosed into single
quotes. Using double quotes adds a bit more flexibility, especially
about the task name referred by `start_at_task` option.
It also aligns with the handling of the '--extra-vars' parameter
(see cb80286).
Without this change, the JSON string generated from the `extra_vars`
Ruby hash is passed without enclosing quotes and is then not parseable
by the ansible-playbook command when exectuted in a usual shell context.
In this changeset, the ansible (remote) unit test coverage is improved
to cover both usage of `extra_vars` (ansible_local unit tests are still
missing).
Additional Notes:
- Double quotes are favored to single quotes in order to allow usage of
any character for the variable values. For this reason additional
escaping is appended to JSON-inner double quotes and backslashes.
- This problem was not affecting the `ansible` remote provisioner
(which is running the ansible-playbook command via the childprocess
Ruby library). But with this change, the `verbose` output will also
now be correct for a copy-paste reuse.
- After this change, all the "--extra-vars" arguments (also a var
file passed with the @-syntax or anything coming via the
`raw_arguments` option) are "blindly" and systematically enclosed
in double quoted and double-escaped.
This is not optimal and can potentially break with peculiar values
(e.g. a double quote character (") cannot be used in a json value
when using `raw_arguments`). That said, I think that the current
solution is a reasonable trade-off, since the official `extra_vars`
option should now be able to cover a great majority of use cases.
Fix#6726
Before this change, the detection of a non-existing path on the guest
machine was considered as an error and lead to interrupt the current vagrant
action. This was actually a mistake to do so, since the config checks
are performed before many other vagrant actions than `provision`.
The config.validate phase is also intended to primarily check the options
sanity, but it cannot be too strict with the guest state (which can easily
get "out of automatic control").
With this change, we still apply these checks (when possible), but only warn
about possible configuration problems. This way, the subsequent
statements will happen anyway (e.g. ansible commands will be
executed, vagrant machine will be destroyed, etc.)
At least for ansible 2.0.0.1 the command `ansible-galaxy --help` is inappropriate for testing if ansible is installed, as it yields an error:
```
vagrant@vagrant-ubuntu-trusty-64:~$ ansible-galaxy --help && echo "OK"
Usage: ansible-galaxy [delete|import|info|init|install|list|login|remove|search|setup] [--help] [options] ...
Options:
-h, --help show this help message and exit
-v, --verbose verbose mode (-vvv for more, -vvvv to enable connection
debugging)
--version show program's version number and exit
ERROR! Missing required action
```
In cd93721, I relied on a suprising combination of quotes to protect ssh
execution to strip the quoted path to the private key file.
Since any ssh command line argument can be passed via
`ANSIBLE_SSH_ARGS`, it is quite more readable and easy to rely on the
`-i` argument, which is not affected like `-o IdentityFile=...` and also
supports multiple occurences.

Finally fix#6671
Note that I decided to not squash both commits for better
documentation and traceability.
Surprisingly (to me at least), a simple quote enclosure was not enough
to fix the problem.
Caveat: the stringified ansible-playbook command logged in verbose mode
is wrongly formatted (no quotes are escaped).
Fix#6671
Like in the (remote) `ansible` provisioner, it is preferred to pass the
directory that contains the generated inventory file. This way, advanced
inventory usages can be achieved by adding more inventory files into the
same directory.

String and Symbol types are different when used as a Hash key. By
default the Vagrant machine names are set in Symbol format, but users
may write their `host_vars` entries with String keys. This is a very
simple way to ensure smooth experience, without having to coerce the
data types during the config validation (e.g. with a library like
Hashie, which is currently not in the Vagrant dependencies)

I missed to rename the refactored exceptions as AnsibleCommandFailed in
the guest-based parts. The lack of unit tests for these parts hurts...
on my agenda, I swear!
See c1f3d114f5
With this change, the existing host-based Ansible provisioner is
refactored to share a maximum of code with this new guest-based Ansible
provisioner.
At this stage of development, the existing unit tests are intentionally
modified as little as possible, to keep safe the existing funtionalities.
Other issues resolved by this changeset:
- Display a warning when running from a Windows host [GH-5292]
- Do not run `ansible-playbook` in verbose mode when the `verbose` option
is set to an empty string.
The benefits of the following "breaking change" are the following:
- default behaviour naturally fits with most common usage (i.e. always
connect with Vagrant SSH settings)
- the autogenerated inventory is more consistent by providing both the
SSH username and private key.
- no longer needed to explain how to override Ansible `remote_user` parameters
Important: With the `force_remote_user` option, people still can fall
back to the former behavior (prior to Vagrant 1.8.0), which means that
Vagrant integration capabilities are still quite open and flexible.
When provisioning multiple machines in sequence (the default vagrant
behaviour), it doesn't make sense to require to provide the private ssh
key(s) via the custom ansible inventory script/file.
To align with the handling of multiple ssh keys per machine, we won't
rely any longer on `--private-key` command line argument, but only pass
the keys via `ANSIBLE_SSH_ARGS` environment variable.
Note that when vagrant generates the ansible inventory and that only one
key is associated to a VM, this step would be redundant, and therefore
won't be applied.
This change fixes the breaking change introduced by 3d62a91.
Vagrant 1.7.1 creates and injects new ssh keys for each virtual machine.
When it started ansible with the "parallel provisioning trick",
it would only send the ssh key of the targeted virtual machine.
With this change, vagrant now stores the ssh key for each virtual
machines directly in the generated ansible inventory, and thus allow
ansible parallelism.
Note that this change is not sufficient, as it would break vagrant
configuration based on a custom inventory (file or script). This issue
will be addressed in a next commit.

The Ansible Vagrant provisioner has a race where the inventory file is
updated every time the provisioner runs unless a file is provided.
Therefore if Ansible attempts to provision two nodes in parallel, you
may see the following race:
* System A writes the inventory file and calls Ansible.
* System B starts to provision and truncates the file before
creating a new one.
* Ansible on system A now attempts to read the inventory
file, which is blank. Ansible bombs out with "ERROR: provided
hosts list is empty".
To fix this, we only allow Vagrant to update the inventory file if
it needs to.
Revert 1c884fa4e5 which introduced the
following bug:
Instead of allowing to dump the `ansible-playbook` command details when
VAGRANT_LOG=debug was defined, it was then impossible to disable this
console output when VAGRANT_LOG was undefined (in such case,
``@logger.debug? systematically returns `true`)
In order to keep things simple and focused, it is preferable to drop the
bad idea to mix Ansible verbosity and Vagrant log level.
Fix#5803
After #5532 (e745436df3), it was no longer
possible to enable ansible colorized output. Even though
`ANSIBLE_NOCOLOR` has no effect *at the moment* in vagrant+ansible
integration, I agree to keep it for clarity and consistence.
The new `--no-color` behaviour (bug fix#5531) is now covered by a unit
test.
//cc @marsam, @sethvargo
This change helps to avoid troubles like reported in #5018 and #4860.
Note that for sake of configuration simplicity, no new `ansible.timeout`
option has been added. The users who want to set a different value can
rely on `ansible.raw_arguments`.
This SSH option is always set, except when Vagrant is running from an
operating system fo the Solaris-family, as this parameter is not
supported by SunSSH. Logic taken from
