* Populate push configs when parsing the vagrantfile
* Allow untyped configs to be shipped over GRPC
* In our demo plugin, walk the vagrantfile and snag the config
Example Vagrantfile that works with the demo plugin:
```ruby
Vagrant.configure("2") do |config|
config.push.define "myplugin" do |push|
push.coolkey = "coolvalue"
push.alist = ["so", "many", "items"]
push.ahash = { "hashkey" => "hashvalue" }
end
end
```
Prior to this commit, vagrant was not grabbing all of the tokens on
Windows for showing the full drive because the ruby api for it behaves
differenly on windows compared to other platforms. This commit changes
that by ensuring the letter drive is attached to the path when showing
an exception.
This commit adds a new flag to the `vagrant validate` command which
allows users to completely ignore the provider block of a config file.
This is useful for when you are running `vagrant validate` in CI and
don't want to install a valid provider to check the syntax of your
Vagratnfile. When the flag is invoked, a warning will be displayed
saying that the provider block will be ignored and not validated.
This commit adds some additional handling for when Vagrant loads config
files. Instead of showing the basic ruby exception, it prints a more
helpful error message and tries to direct the user to the line number
and file where the exception is occuring.
Prior to this commit, if a user set the env var VAGRANT_HOME to be the
same directory where the project home is, Vagrant would load that file
twice and merge its config. This caused various provisioner and other
provider blocks to unexpectedly run twice. This commit updates the
config loader to look and see if the `:root` and `:home` procs are
equal, and if so, removes the `:home` object so that it isn't loaded and
duplicated. This commit however does not prevent duplicate loading if an
identical Vagrantfile exists in the home and project dir if those
locations are different.
Here we implement a naive solution to #5605 which catches the case that
a provided source contains an object which cannot be inspected, because
an object contained within in has an #inspect string that returns a
string that is incompatible with the encoding in
`Encoding.default_external` or a string which cannot be downcast to
7-bit ascii.
The Ruby VM implementation of "#inspect" implements this checking on
these lines of code: http://git.io/vZYNS. A Ruby level override of
this method does not cause this problem. For example:
```ruby
class Foo
def inspect
"😍".encode("UTF-16LE")
end
```
will not cause the problem, because that's a Ruby implementation and the
VM's checks don't occur.
However, if we have an Object which **does** use the VM implementation
of inspect, that contains an object that has an inspect string which
returns non-ascii, we encounter the bug. For example:
```ruby
class Bar
def inspect
"😍".encode("UTF-16LE")
end
end
class Foo
def initialize
@bar = Bar.new
end
end
Foo.new.inspect
```
Will cause the issue.
The solution this patch provides basically catches the encoding error
and inserts a string which attempts to help the user work out which
object was provided without blowing up. Most likely, this was caused
by a user having a weird encoding coming out of one of the sources
passed in, but without a full repro case, it's not clear whether a patch
should be applied to a different object in the system.
Closes#5605.
If the Vagrantfile has some kind of error, display not only
its path and the exception message, but also the originating
line number and exception class.
Also log the full backtrace when the error is in a provider
block, just as it is done when it's outside a provider block.
This fixes the problem when config keys collide with Kernel/Object
methods (private). An example is `exec` which is used in vagrant-exec
plugin.
