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
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.)
In our test environments, it's good to be able to roll back to the same,
anonymous, snapshot repeatedly. This patch adds a `--no-delete` option
to the `snapshot pop` command allowing this.
This makes the new core snapshot behaviour more consistent with what we
were doing with vagrant-multiprovider-snap
(https://github.com/scalefactory/vagrant-multiprovider-snap)
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
