Some Atlas usage patterns expect to be able to override a variable set
in Atlas, even if it's not seen in the local context. This allows
overwriting a variable that is returned from atlas, and sends it back.
Also use a unique sential value in the context where we have variables
from atlas. This way atals variables aren't combined with the local
variables, and we don't do something like inadvertantly change the type,
double encode/escape, etc.
The handling of remote variables was completely disabled for push.
We still need to fetch variables from atlas for push, because if the
variable is only set remotely the Input walk will still prompt the user
for a value. We add the missing remote variables to the context
to disable input.
We now only handle remote variables as atlas.TFVar and explicitly pass
around that type rather than an `interface{}`.
Shorten the text fixture slightly to make the output a little more
readable on failures.
The strings we have in the variables may contain escaped double-quotes,
which have already been parsed and had the `\`s removed. We need to
re-escape these, but only if we are in the outer string and not inside an
interpolation.
Add tf_vars to the data structures sent in terraform push.
This takes any value of type []interface{} or map[string]interface{} and
marshals it as a string representation of the equivalent HCL. This
prevents ambiguity in atlas between a string that looks like a json
structure, and an actual json structure.
For the time being we will need a way to serialize data as HCL, so the
command package has an internal encodeHCL function to do so. We can
remove this if we get complete package for marshaling HCL.
This is the first step in allowing overrides of map and list variables.
We convert Context.variables to map[string]interface{} from
map[string]string and fix up all the call sites.
VCS detection was on by default, and blows up when the tests are run in
a copy of the Terraform source that is not a git repository, like - say
- during a Homebrew formula install, just to pick a random example. :)
