Martin Atkins 73abb6e8f4 command: Re-enable showing outputs after successful "apply"
We temporarily disabled this because it needed some further work to update
it for the new state models, which has now been done.

We no longer need the configuration objects for the outputs because the
state itself contains all of the information needed for displaying these.

Martin Atkins 53bb3f57e6 command: Remove tests related to legacy remote state migrations, etc
We no longer support legacy remote state, so the behaviors these tests
were covering are no longer present.

Martin Atkins 275a44f552 command: Reinstate object ids in the UIHook progress logs
We used to treat the "id" attribute of a resource as special and elevate
it into its own struct field "ID" in the state, but the new state format
and provider protocol treats it just as any other attribute.

However, it's still useful to show the value of a single identifying
attribute when there isn't room in the UI for showing all of the
attributes, and so here we take a new strategy of considering "id" along
with some other conventional names as special only in the UI layer.

This new heuristic approach can be adjusted over time as new provider
patterns emerge, but for now it covers some common conventions we've seen
in real providers.

With that said, since all existing providers made for Terraform versions
prior to v0.12 were forced to set "id", we won't see any use of other
attributes here until providers are updated to remove the placeholder
ids they were generating in cases where an id was not actually relevant
but was forced by the old protocol. At that point the UX should be
improved by showing a more relevant attribute instead.

We now also allow for the possibility of no id at all, since that is valid
for resources that exist only within the Terraform state, like the ones
from the "random" and "tls" providers.

Martin Atkins 43d5206d82 command: Stub the "terraform state mv" tests to remind to fix
This command isn't yet updated for the new state types, but since we were
not returning a non-successful error status here the tests were just
failing in a weird way instead. Now we'll fail with a message that makes
it clear there is still work to do in the real implementation here.

Martin Atkins 1d64ce8ec0 command: Fix "terraform validate" tests
We now need to give a provider schema that the test fixtures conform to,
so we can validate against it.

Martin Atkins 025540789c command: Restore the "terraform output" functionality
We previously stubbed most of this out because it hadn't yet been updated
to support the new state types, etc.

This restores all of the previous behavior as covered by the tests.

We intentionally remove one behavior that was not covered by the tests:
we used to allow retrieval of outputs from non-root modules using the
-module option, but since we no longer persist non-root outputs in the
state we can no longer support this without a full expression evaluation
walk, and that'd be overkill for this otherwise-simple command. Descendant
module outputs are not part of the public interface of a configuration
anyway, so accessing them from outside in this way is an anti-pattern.

(For debugging scenarios it is still possible to access these from
"terraform console", which _does_ do a full evaluation graph walk to
prepare its evaluation scope.)

Martin Atkins feff10dcb5 command: Fix TestGraph_plan
The plan file writer requires a backend config to be present, but we don't
really need one for the sake of _this_ test, since we don't activate the
backend to render a plan graph, and so we just write in a placeholder.

Martin Atkins c0baedac84 command: Fix tests for "terraform fmt" command
Some underlying assumptions have shifted here, so although the behavior
is still broadly the same we need to accommodate some different details.

Martin Atkins de3944b9bf command: collect root module variable values for apply/plan/refresh
This connects a missing link left by earlier refactoring: the command
package is responsible for gathering up variable values provided by the
user and passing them through to the backend to use in operations.

Martin Atkins c5940f2438 backend/local: Increase log verbosity for backend context construction
There are several steps here and a number of them can include reaching out
to remote servers or executing local processes, so it's helpful to have
some trace logs to better narrow down causes of errors and hangs during
this step.

Martin Atkins 34c4fd316d command: Update backend-unchanged fixture for new expectations
Our serialization of the backend configuration has changed slightly for
Terraform 0.12 due to reimplementing it in terms of the HCL2 types, so
the base case that should be unchanged during the test needs to be
changed.

Martin Atkins 34ebde0b95 command/format: be resilient to incomplete schema when formatting state
In all real cases the schemas should be populated here, but we don't want
to panic in UI rendering code if there's a bug here.

This can also be tripped up by tests with incomplete mocks. It's
unfortunate that this can therefore mask some problems in tests, but tests
can protect against it by asserting on specific output text rather than
just assuming that a zero exit status is a pass.

Martin Atkins a6f399517b backend/local: reinstate additional steps in plan file processing
In earlier refactoring we skipped implementing prior state safety checks,
propagating the target addresses from plan, and verifying that all of
the providers are exactly the same from the plan being created.

This change reinstates those checks, including a new error message for
the "stale plan" situation.

Martin Atkins d63c2fdd8d command: Show snippet of invalid resource addresses in import
If we fail to parse the resource address given to "terraform import" then
it's helpful to produce a "source code" snippet of what the user provided
so they might see more precisely which part of the address was invalid.

Martin Atkins 1bc10180cb command: Fix all of the "taint" command tests
Most of this is just updates to allow for the fact that we now always save
the provider address as part of resource state, whereas before it was only
saved conditionally.

This also updates TestTaint_module for the intentional change that it now
expects a child module to be specified using normal resource address
syntax, rather than as a separate -module option.

Martin Atkins 8321c3614f command: Fix TestUntaint_module
The untaint command now uses normal resource address syntax to specify the
module path, rather than passing it in as a separate argument.

Martin Atkins 3cee60ee3a command: Fix various "untaint" command tests
Resource instance state now always includes the provider address fo each

Added a very simple test with state and schema.
TODO: if tests are added we should test using golden files (and example
state files, instead of strings). This seemed unnecessary with the
simple test cases.

Martin Atkins e8240087fe command: Populate backend configuration in plan files
In previous work we didn't quite connect these dots. The connection here
is sub-awesome since the existing interfaces here had some unfortunate
assumptions that we'd like to move away from (like the idea of a "nil
backend" implying the local backend) but we're accepting this for now to
avoid another big round of refactoring.

The main implication of this is that we will now always include a backend
configuration in the plan, though it might just be a placeholder config
for the local backend in the remaining cases where that's still implicitly
set. Later we will change this so that there is no implicit local backend
at all (terraform init is always required, _it_ will deal with setting
implicitly setting the local backend when appropriate), which will allow
us to rework this to be more straightforward and less "spooky".

Martin Atkins cbc548eb36 command: Do CLI init of backend loaded from plan
If we don't do this, we can't produce any output when applying a saved
plan file.

Here we also introduce a check to the local backend's ReportResult
function so that it won't panic if CLI init is skipped, although that
will no longer happen in the apply-from-file case due to the change
described in the previous paragraph.

Martin Atkins 2b80df0163 backend/local: Require caller to set PlanOutBackend with PlanOutPath
We can't generate a valid plan file without a backend configuration to
write into it, but it's the responsibility of the caller (the command
package) to manage the backend configuration mechanism, so we require it
to tell us what to write here.

This feels a little strange because the backend in principle knows its
own config, but in practice the backend only knows the _processed_ version
of the config, not the raw configuration value that was used to configure
it.

Kristin Laemmert 2d3cb87789 backend/local tests tests tests
converted the existing testPlanState() from terraform.State to
states.State to fix various plan tests.

reverted the "bandaid" in plans/planfile/tfplan.go - at this moment the
backend tests do not include backend configuration, and so the planfile
package can write the plan file but not read it back in. That will be
revisted in a separate track of work.

Kristin Laemmert 6a37ee9277 backend/local: more tests passing
I have no confidence in the change to plans/planfile/tfplan.go. The
tests were passing an empty backend config, which planfile  was able to
write to a file but not read from the same file. This change let me move
past that and it did not break any tests in the planfile package, but I
am concerned that it introduces undesired behavior.

James Bardin f54113ec08 remove unneeded legacy test
The legacy test wasn't really testing anything useful, just the plan
behavior with no diff in a module returned a module with no diff.
There's no reason to convert this to the new plans, since there's no
legacy behavior to match.
