Because Vagrant requires certain versions of Bundler in order to work properly, the correct version of Bundler must be installed manually. I gathered this information from a couple of sources.
It's handy to have this information in this specific guide :)
Call it with "--no-pager"
Without it, if the user has a pager (more/less/etc.) configured and
call vagrant up with NFS shares, systemctl would use the pager, and
that would probably require an unnecessary key press from the user.
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).
When updating the inventory, write to a temp file and replace the
original once writing is complete, to allow for an atomic replacement
of the contents.
Ensures that ansible reading an inventory file will get either the old
or new contents, but never the truncated version of the file that
appears should you open it with 'w' mode set to replace the contents.
Solves the 'provided hosts list is empty' error, which is emitted by
ansible should it manage to be reading the inventory file just as it
was truncated, but before the new contents were flushed to disk.
Partially-Fixes: #6526
Ensure multi machine access of other machine state information through
iterating `active_machines` and retrieval of cached machines cannot
have multiple threads update the state of machines simultaneously as
this triggers a Machine Lock exception.
Machine state information retrieved from the index, returns a locked
object. Since iteration of active_machine, and retrieval of each
machine from the cache can be triggered by any plugin, it is possible
for another machine to inadvertently access the state and trigger an
update, which the thread owning the machine is currently in the process
of updating it already. This results in a Machine Locked exception
occurring if the attempt to retrieve the cached state from the index
occurs before the other thread calls release.
