During the 0.12 work we intended to move all of the variable value
collection logic into the UI layer (command package and backend packages)
and present them all together as a unified data structure to Terraform
Core. However, we didn't quite succeed because the interactive prompts
for unset required variables were still being handled _after_ calling
into Terraform Core.
Here we complete that earlier work by moving the interactive prompts for
variables out into the UI layer too, thus allowing us to handle final
validation of the variables all together in one place and do so in the UI
layer where we have the most context still available about where all of
these values are coming from.
This allows us to fix a problem where previously disabling input with
-input=false on the command line could cause Terraform Core to receive an
incomplete set of variable values, and fail with a bad error message.
As a consequence of this refactoring, the scope of terraform.Context.Input
is now reduced to only gathering provider configuration arguments. Ideally
that too would move into the UI layer somehow in a future commit, but
that's a problem for another day.
We previously deferred this to Validate, but all of our operations require
a valid set of variables and so checking this up front makes it more
obvious when a call into Terraform Core from the CLI layer isn't
populating variables correctly, instead of having it fail downstream
somewhere.
It's the caller's responsibility to ensure that it has collected values
for all of the variables in some way before calling NewContext, because
in the main case driven by the CLI there are many different places that
variable values can be collected from and so handling the main user-facing
validation in the CLI allows us to return better error messages that take
into account which way a variable is (or is not) being set.
* command/jsonstate: properly marshal deposed resources
This PR addresses 2 issues: `show -json` would crash if there was not a
`Current` `states.ResourceInstance` for a given resource, and `deposed`
resource instances were not shown at all.
Fixes#22642
self references do not need to be added to `managedResource`, and in
fact that could cause issues later if self is allowed in contexts other
than managed resources.
Coalesce 2 cases in the Referenceable switch, be take the
ContainingResource address of an instance beforehand.
Previously we were using the experimental HCL 2 repository, but now we'll
shift over to the v2 import path within the main HCL repository as part of
actually releasing HCL 2.0 as stable.
This is a mechanical search/replace to the new import paths. It also
switches to the v2.0.0 release of HCL, which includes some new code that
Terraform didn't previously have but should not change any behavior that
matters for Terraform's purposes.
For the moment the experimental HCL2 repository is still an indirect
dependency via terraform-config-inspect, so it remains in our go.sum and
vendor directories for the moment. Because terraform-config-inspect uses
a much smaller subset of the HCL2 functionality, this does still manage
to prune the vendor directory a little. A subsequent release of
terraform-config-inspect should allow us to completely remove that old
repository in a future commit.
If a connection fails and attempts to reconnect after the keep-alive
loop started, the client will be pulled out from under the keep-alive
requests. Close over a local copy of the client, so that reconnecting
doesn't race with the keepalive loop terminating.
copyDir is used in configload/getter.go to copy previously downloaded modules instead of using the go-getter client every time. The go-getter client downloads dotfiles, but copyDir did not copy dotfiles, leading to inconsistent behaviour when reusing the same module source.
Properly wait for cost estimation to finish running before outputting
the results. Waits 500 milliseconds between checks, rather than backing
off exponentially, because we are not in a run queue. At the point we're
waiting, we expect cost estimation to be run in a timely manner.

The acceptance tests for etcdv3, oss and manta were not validating
required env variablea, chosing to assume that if one was running
acceptance tests they had already configured the credentials.
It was not always clear if this was a bug in the tests or the provider,
so I opted to make the tests fail faster when required attributes were
unset (or "").
