Prior to this commit, there was no way to add additional ssh arguments
within a Vagrantfile for a given vagrant machine. This commit introduces
a new option extra_args that allows users to pass in a single argument
or an array of flags that will be added onto the ssh command.
Prior to this commit, if a user ran a vagrant command within a subdir,
it would warn about the cwd changing which is not actually the case.
This commit adds an additional check to see if vagrant is being invoked
within a subdirectory so that it doesn't warn the user.
This commit allows the user to configure two additional options that
were previously not configurable: Compression and DSAAuthentication.
Each config option is set as a boolean, and if left out of the config
will default to its previous behavior which is included and set to
"yes". If the user explicitly sets it to false, it will not be included
as an ssh option.
Whenever the path where the machine was first created changes, Vagrant
will now show just one warning when an action is run on the machine.
The idea is that if a user copies the machine over to a different
directory with the idea of running two different machines, this warning
will now help the user determine how to make that work.
This adds two new SSH configuration options:
- `keys_only`
- `paranoid`
These values were previously hard-coded, but can now be user-specified.
Fixes GH-4275
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.
Partially-Fixes: #6526
With this change, any caller of machine.ssh_info is assured that best
efforts will be done to fix possible wrong permissions on the private
key files.
