This commit include the following changes:
- systematically set ANSIBLE_ROLES_PATH environment variable when
galaxy_roles_path is defined.
- slightly refactor to introduce the concept of "provisioning working
directory" (possible usage in the future for resolving GH-7195)
- fix a bug in ansible-galaxy execution by the ansible_local provisioner
if the paths contains blank characters.
Fix#7269
These changes have been validated against the following guest systems:
- Debian 7 and 8
- Ubuntu 12.04, 14.04 and 16.04
- Fedora 21 and 23
- CentOS 7
- OracleLinux 7
- Scientific Linux 7
At the moment, the pip setup (via get-pip.py script) is not working for
RHEL6-like systems (CentOS 6.6, OracleLinux 6.5, Scientific Linux 6),
because Python 2.6 has been deprecated and is no longer supported by
Python core team. I consider this limitation with low priority in
Vagrant context.
The `:pip` install_mode is currently not implemented for the following
platforms:
- OpenSUSE
- ArchLinux
- FreeBSD
Known Issue: By using get-pip.py script, any previous pip installation
will be most probably overrided. This could be an issue for Python
developers who would prefer to keep their base box setup untouched. In
future iteration, it could be possible to choose to reinstall/upgrade
pip or not. issue for Python developers who would prefer to keep their

Resolve GH-6654
Resolve GH-7167 as the `version` option is now considered to select the
version of Ansible to be installed.
With this change, the presence of Ansible configuration files (like
playbook file, inventory path, galaxy role file, etc.) is no longer
performed by the `config` classes, but by the `provisioner` classes
(at the beginning of the provision command).
This change fixes several issues:
- Resolve#6984 as `provision` method are only executed when remote
(ssh) communication with the guest machine is possible.
- Resolve#6763 in a better way than 4e451c6 initially did.
- Improve the general provisioner speed since the `config` checks are
actually triggered by many vagrant actions (e.g. `destroy`,...), and
can also be triggered multiple times during a vagrant run (e.g. on
callback request made by the machine provider).
Unlike the former `config`-based checks, the provision action won't
collect all the invalid options, but only report the first invalid
option found and abort the execution.
Some unit tests were not implemented yet to save my scarce "open source
contribution time" for other important issues, but they should be done
at last via GH-6633.
Changes:
- Add "config" unit tests for `ansible_local` (guest)
- Share some "config" examples between both ansible provisioners
- Move `config_host.rb` specific examples to `config/host.rb`
- Add a requirement to "../helpers" in `config/guest.rb` in order to be
able to run the related unit tests
References:
- This is the first part of GH-6633 resolution
- This change is a handy prerequisite for GH-6570
Not addressed yet:
- FIXME (guest.rb): Some test-double stubs are currently not working as
expected, and the related checks are commented out for the moment
(no idea why, but this is not urgent to be fixed because of GH-7335
rejection. See also GH-6984)
- FIXME (shared.rb): The guest-based config should actually NOT return
an error when the extra_vars file cannot be found, but only display a
a warning (similarly to the changes done for GH-6763, see 4e451c6)
With this change, the `raw_arguments` and `raw_ssh_args` options are:
- STILL automatically converted as an Array when they are set a String
(no behaviour change)
- rejected if they are not of Array data type otherwise
Additional Notes:
- the 'as_array' tiny helper has been removed since it was no longer
used.
- there is for now no deeper validation (i.e. verifying that the Array
elements are only *String* objects)
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
Previously the default channel was "current", but after discussion with
@coderanger on GH-6979, it seems like this was a poor design decision.
Instead, we should use the stable channel and allow users to opt-in to
prerelease versions.
Fixes GH-6979
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
With the introduction of inventory variables, group members provided as
String are not splitted (by ' ') into an array (instead of
auto-conversion to a single-item array).
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)

At the moment, the vagrant ssh username is used as default username when
force_remote_user option is disabled, even for winrm-communiating
machines. This could be improved in the future, but people hitting this
problem can easily work around it by syncing `config.ssh.unsername` and
`config.winrm.username` in their Vagrantfile.
ref #5086
This is required because the Chef Server almost always needs a node name to
interact. This will default to the hostname, but that's always going to be
`vagrant.vm`, which will collide easily.
This generates a random hostname with `vagrant-` as the prefix and stores the
result in the machine's data directory.
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.
