remove UnknownVariabeValue from config and update references to shim 2019-07-17 22:41:24 -04:00
James Bardin c8a2f3840b remove SkipCoreTypeCheck
This experiment is no longer needed for handling computed blocks, since
the legacy SDK can't reasonably handle Dynamic types, we need to remove
this before the final release.

Remove LegacySchema functions as well, since handling SkipCoreTypeCheck
was the only thing left they were handling.

James Bardin 67395306e1 delete unknown values from apply config altogether
removeConfigUnknowns need to remove the value completely from the config
map. Removing this value allows GetOk and GetOkExists to indicate if the
value was set in the config in the case of an Optional+Computed
attribute.

Martin Atkins 861a2ebf26 helper/schema: Use a more targeted shim for nested set diff applying
We previously attempted to make the special diff apply behavior for nested
sets of objects work with attribute mode by totally discarding attribute
mode for all shims.

In practice, that is too broad a solution: there are lots of other shimming
behaviors that we _don't_ want when attribute mode is enabled. In
particular, we need to make sure that the difference between null and
empty can be seen in configuration.

As a compromise then, we will give all of the shims access to the real
ConfigMode and then do a more specialized fixup within the diff-apply
logic: we'll construct a synthetic nested block schema and then use that
to run our existing logic to deal with nested sets of objects, while
using the previous behavior in all other cases.

In effect, this means that the special new behavior only applies when the
provider uses the opt-in ConfigMode setting on a particular attribute,
and thus this change has much less risk of causing broad, unintended
regressions elsewhere.

James Bardin 5f52aba3ae Remove unknown value strings from apply diffs
The synthetic config value used to create the Apply diff should contain
no unknown config values. Any remaining UnknownConfigValues were due to
that being used as a placeholder for values yet to be computed, and
these should be marked NewComputed in the diff.

James Bardin 8730d99309 LegacyResourceSchema to remove 0.12 features
This allows us to call CoreConfigSchema and return something that looks
like the original schema.

Martin Atkins 1987a92386 helper/schema: Implementation of the AsSingle mechanism
The previous commit added a new flag to schema.Schema which is documented
to make a list with MaxItems: 1 be presented to Terraform Core as a single
value instead, giving a way to switch to non-list nested resources without
it being a breaking change for Terraform v0.11 users as long as it's done
prior to a provider's first v0.12-compatible release.

This is the implementation of that mechanism. It's intentionally
implemented as a suite of extra fixups rather than direct modifications to
existing shim code because we want to ensure that this has no effect
whatsoever on the result of a resource type that _isn't_ using AsSingle.

Although there is some small unit test coverage of the fixup steps here,
the primary testing for this is in the test provider since the integration
of all of these fixup steps in the correct order is the more important
result than any of the intermediate fixup steps.

James Bardin 21dfa56766 use ShimInstanceStateFromValue in DiffFromValues
This makes sure the diff is generated with the matching set ids from
helper/schema.

Update the tests to add ID fields to the state, which will exists in
practice, since any state traversing through the shims will have the ID
inserted.

James Bardin df04e2e7a6 move InstanceState shim into schema.Resource
This was the resource can rebuild the flatmapped state using the
schema and ResourceData, providing us the the correct set key values.

James Bardin 46b4c27dbe create a SimpleDiff for the new provider shims
Terraform now handles any actual "diffing" of resource, and the existing
Diff functions are only used to shim the schema.Provider to the new
methods. Since terraform is handling what used to be the Diff, the
provider now should not modify the diff based on RequiresNew due to it
interfering with the ignore_changes handling.

James Bardin 0d4d572c39 start work on helper/resource test fixtures
The helper resource tests won't pass for now, as they use a
terraform.MockProvider which can't be used in the schema.Provider shims.

Martin Atkins 33151f5011 core: Move StateValueFromInstanceState shim from helper/schema
This one doesn't depend on any helper/schema specific bits and it'll also
be useful for the shims in our mock provider in core.

Martin Atkins 76d11f44cc core: Move some of the helper/schema shims so provider mock can use them
The old names are now wrappers around these new functions.

James Bardin a87470cc15 resource ids must always have a value
The "id" field is assumed to always exist, and must have a valid value.
Set "id" to unknown when planning new resource changes to indicate that
it will be computed.

James Bardin dcaf5aa262 add some of the shims used for the grpc provider
This adds some of the required shim functions to the schema package.
While this further bloats the already huge package, adding the helpers
here was significantly less disruptive than refactoring types into
separate packages to prevent import cycles.

The majority of tests here are directly adapted from existing schema
tests to provide as many known good values to the shims as possible.
