* command: keep our promises
* remove some nil config checks
Remove some of the safety checks that ensure plan nodes have config attached at the appropriate time.
* add GeneratedConfig to plan changes objects
Add a new GeneratedConfig field alongside Importing in plan changes.
* add config generation package
The genconfig package implements HCL config generation from provider state values.
Thanks to @mildwonkey whose implementation of terraform add is the basis for this package.
* generate config during plan
If a resource is being imported and does not already have config, attempt to generate that config during planning. The config is generated from the state as an HCL string, and then parsed back into an hcl.Body to attach to the plan graph node.
The generated config string is attached to the change emitted by the plan.

Add a new ChangeReason, ReasonDeleteBecauseNoMoveTarget, to provide better
information in cases where a planned deletion is due to moving a resource to
a target not in configuration.
Consider a case in which a resource instance exists in state at address A, and
the user adds a moved block to move A to address B. Whether by the user's
intention or not, address B does not exist in configuration.
Terraform combines the move from A to B, and the lack of configuration for B,
into a single delete action for the (previously nonexistent) entity B.
Prior to this commit, the Terraform plan will report that resource B will be
destroyed because it does not exist in configuration, without explicitly
connecting this to the move.
This commit provides the user an additional clue as to what has happened, in a
case in which Terraform has elided a user's action and inaction into one
potentially destructive change.
This is a new-shaped representation of check results which follows the
two-tiered structure of static objects and dynamic instances of objects,
thereby allowing consumers to see which checkable objects exist in the
configuration even if a dynamic evaluation error prevented actually
expanding them all to determine their declared instances.
Eventually we'll include this in the state too, but this initially adds it
only to the plan in order to replace the now-deprecated experimental
conditions result that was present but undocumented in Terraform v1.2.
A significant goal of the design changes around checks in earlier commits
(with the introduction of package "checks") was to allow us to
differentiate between a configuration object that we didn't expand at all
due to an upstream error, which has _unknown_ check status, and a
configuration object that expanded to zero dynamic objects, which
therefore has a _passing_ check status.
However, our initial lowering of checks.State into states.CheckResults
stayed with the older model of just recording each leaf check in isolation,
without any tracking of the containers.
This commit therefore lightly reworks our representation of check results
in the state and plan with two main goals:
- The results are grouped by the static configuration object they came
from, and we capture an aggregate status for each of those so that
we can differentiate an unknown aggregate result from a passing
aggregate result which has zero dynamic associated objects.
- The granularity of results is whole checkable objects rather than
individual checks, because checkable objects have durable addresses
between runs, but individual checks for an object are more of a
syntactic convenience to make it easier for module authors to declare
many independent conditions that each have their own error messages.
Since v1.2 exposed some details of our checks model into the JSON plan
output there are some unanswered questions here about how we can shift to
reporting in the two-level heirarchy described above. For now I've
preserved structural compatibility but not semantic compatibility: any
parser that was written against that format should still function but will
now see fewer results. We'll revisit this in a later commit and consider
other structures and what to do about our compatibility constraint on the
v1.2 structure.
Otherwise though, this is an internal-only change which preserves all of
the existing main behaviors of conditions as before, and just gets us
ready to build user-facing features in terms of this new structure.
The "checks" package is an expansion what we previously called
plans.Conditions to accommodate a new requirement that we be able to track
which checks we're expecting to run even if we don't actually get around
to running them, which will be helpful when we start using checks as part
of our module testing story because test reporting tools appreciate there
being a relatively consistent set of test cases from one run to the next.
So far this should be essentially a no-op change from an external
functionality standpoint, aside from some minor adjustments to how we
report some of the error and warning cases from condition evaluation in
light of the fact that the "checks" package can now track errors as a
different outcome than a failure of a valid check.
As is often the case with anything which changes what we track
in the EvalContext and persist between plan and apply, Terraform Core is
pretty brittle and so this had knock-on effects elsewhere too. Again, the
goal is for these changes to not create any material externally-visible
difference, and just to accommodate the new assumption that there will
always be a "checks" object available for tracking during a graph walk.
Go 1.19's "fmt" has some awareness of the new doc comment formatting
conventions and adjusts the presentation of the source comments to make
it clearer how godoc would interpret them. Therefore this commit includes
various updates made by "go fmt" to acheve that.
In line with our usual convention that we make stylistic/grammar/spelling
tweaks typically only when we're "in the area" changing something else
anyway, I also took this opportunity to review most of the comments that
this updated to see if there were any other opportunities to improve them.
The JSON output for sequences previously omitted unknown values for
tuples and sets, which made it impossible to interpret the corresponding
unknown marks. For example, consider this resource:
resource "example_resource" "example" {
tags = toset(["alpha", timestamp(), "charlie"])
}
This would previously be encoded in JSON as:
"after": {
"tags": ["alpha", "charlie"]
},
"after_unknown": {
"id": true,
"tags": [false, true, false]
},
That is, the timestamp value would be omitted from the output
altogether, while the corresponding unknown marks would include a value
for each of the set members.
This commit changes the behaviour to:
"after": {
"tags": ["alpha", null, "charlie"]
},
"after_unknown": {
"id": true,
"tags": [false, true, false]
},
This aligns tuples and sets with the prior behaviour for lists, and
makes it clear which elements are known and which are unknown.
Planned output changes are represented in the JSON output format using
the same change object as planned resource changes. This structure
includes an `after` value and a parallel `after_unknown` value, which
can be combined to determine which specific parts of a value are known
only at apply time.
Previously, structured output values would be marked in the JSON plan as
coarsely known or unknown, even if only some subset of the structure
will be known only at apply time. This simplification was unnecessary,
and this commit reuses the same logic for resource changes to give more
information to consumers of this format.
For example, consider this output:
output "bar" {
value = tolist([
"hello",
timestamp(),
"world",
])
}
The plan output for this output would be:
+ bar = [
+ "hello",
+ (known after apply),
+ "world",
]
For the same plan, the JSON output was previously:
"bar": {
"actions": [
"create"
],
"before": null,
"after_unknown": true,
"before_sensitive": false,
"after_sensitive": false
}
After this commit, the output is instead:
"bar": {
"actions": [
"create"
],
"before": null,
"after": [
"hello",
null,
"world"
],
"after_unknown": [
false,
true,
false
],
"before_sensitive": false,
"after_sensitive": false
}
We have two different reasons why a data resource might be read only
during apply, rather than during planning as usual: the configuration
contains unknown values, or the data resource as a whole depends on a
managed resource which itself has a change pending.
However, we didn't previously distinguish these two in a way that allowed
the UI to describe the difference, and so we confusingly reported both
as "config refers to values not yet known", which in turn led to a number
of reasonable questions about why Terraform was claiming that but then
immediately below showing the configuration entirely known.
Now we'll use our existing "ActionReason" mechanism to tell the UI layer
which of the two reasons applies to a particular data resource instance.
The "dependency pending" situation tends to happen in conjunction with
"config unknown", so we'll prefer to refer that the configuration is
unknown if both are true.
Previously the supported JSON plan and state formats included only
serialized output values, which was a lossy serialization of the
Terraform type system. This commit adds a type field in the usual cty
JSON format, which allows reconstitution of the original value.
For example, previously a list(string) and a set(string) containing the
same values were indistinguishable. This change serializes these as
follows:
{
"value": ["a","b","c"],
"type": ["list","string"]
}
and:
{
"value": ["a","b","c"],
"type": ["set","string"]
}
In order to include condition block results in the JSON plan output, we
must store them in the plan and its serialization.
Terraform can evaluate condition blocks multiple times, so we must be
able to update the result. Accordingly, the plan.Conditions object is a
map with keys representing the condition block's address. Condition
blocks are not referenceable in any other context, so this address form
cannot be used anywhere in the configuration.
The commit includes a new test case for the JSON output of a
refresh-only plan, which is currently the only way for a failing
condition result to be rendered through this path.
Add the resource instances and individual attributes which may have
contributed to the planned changes to the json format of the plan. We
use the existing path encoding for individual attributes, which is
already used in the replace_paths change field.
When calculating the unknown values for JSON plan output, we would
previously recursively call the `unknownAsBool` function on the current
sub-tree twice, if any values were unknown. This was wasteful, but not
noticeable for normal Terraform resource shapes.
However for deeper nested object values, such as Kubernetes manifests,
this was a severe performance problem, causing `terraform show -json` to
take several hours to render a plan.
This commit reuses the already calculated unknown value for the subtree,
and adds benchmark coverage to demonstrate the improvement.
The JSON plan configuration data now includes a `full_name` field for
providers. This addition warrants a backwards compatible increment to
the version number.
