Martin Atkins 05caff2ca3 Move tfdiags/ to internal/tfdiags/
This is part of a general effort to move all of Terraform's non-library
package surface under internal in order to reinforce that these are for
internal use within Terraform only.

If you were previously importing packages under this prefix into an
external codebase, you could pin to an earlier release tag as an interim
solution until you've make a plan to achieve the same functionality some
other way.

Paddy Carver 6c57395ef3 Test empty diagnostics.
Add a test for a diagnostic with no steps to make sure it still gets
associated with the resource in the config. Follow up to #27710 using
@alisdair's suggested testing.

Paddy Carver c840e9c4bc Fix empty diags not getting associated with source.
Right now, there's a bug that if a diagnostic comes back from the
provider with an AttributePath set, but no steps in the AttributePath,
Terraform _thinks_ it's an attribute-specific diagnostic and not a
whole-resource diagnostic, but then doesn't associate it with any
specific attribute, meaning the diagnostic doesn't get associated with
the config at all.

This PR changes things to check if there are any steps in the
AttributePath before deciding this isn't a whole-resource diagnostic,
and if there aren't, treats it as a whole-resource diagnostic, instead.

See hashicorp/terraform-plugin-sdk#561 for more details on how this
surfaces in the wild.

Add support for provider metadata to modules. (#22583)
Implement a new provider_meta block in the terraform block of modules, allowing provider-keyed metadata to be communicated from HCL to provider binaries.

Bundled in this change for minimal protocol version bumping is the addition of markdown support for attribute descriptions and the ability to indicate when an attribute is deprecated, so this information can be shown in the schema dump.

Martin Atkins 88e76fa9ef configs/configschema: Introduce the NestingGroup mode for blocks
In study of existing providers we've found a pattern we werent previously
accounting for of using a nested block type to represent a group of
arguments that relate to a particular feature that is always enabled but
where it improves configuration readability to group all of its settings
together in a nested block.

The existing NestingSingle was not a good fit for this because it is
designed under the assumption that the presence or absence of the block
has some significance in enabling or disabling the relevant feature, and
so for these always-active cases we'd generate a misleading plan where
the settings for the feature appear totally absent, rather than showing
the default values that will be selected.

NestingGroup is, therefore, a slight variation of NestingSingle where
presence vs. absence of the block is not distinguishable (it's never null)
and instead its contents are treated as unset when the block is absent.
This then in turn causes any default values associated with the nested
arguments to be honored and displayed in the plan whenever the block is
not explicitly configured.

The current SDK cannot activate this mode, but that's okay because its
"legacy type system" opt-out flag allows it to force a block to be
processed in this way anyway. We're adding this now so that we can
introduce the feature in a future SDK without causing a breaking change
to the protocol, since the set of possible block nesting modes is not
extensible.

Martin Atkins 72e279e6b2 providers: Consistently use int64 for schema versions
The rest of Terraform is still using uint64 for this in various spots, but
we'll update that gradually later. We use int64 here because that matches
what's used in our protobuf definition, and unsigned integers are not
portable across all of the protobuf target languages anyway.

Martin Atkins 4fe9632f09 plugin: Establish our current plugin protocol as version 5
The main significant change here is that the package name for the proto
definition is "tfplugin5", which is important because this name is part
of the wire protocol for references to types defined in our package.

Along with that, we also move the generated package into "internal" to
make it explicit that importing the generated Go package from elsewhere is
not the right approach for externally-implemented SDKs, which should
instead vendor the proto definition they are using and generate their
own stubs to ensure that the wire protocol is the only hard dependency
between Terraform Core and plugins.

After this is merged, any provider binaries built against our
helper/schema package will need to be rebuilt so that they use the new
"tfplugin5" package name instead of "proto".

In a future commit we will include more elaborate and organized
documentation on how an external codebase might make use of our RPC
interface definition to implement an SDK, but the primary concern here
is to ensure we have the right wire package name before release.

Martin Atkins e25f79ed28 plugin/convert: Show approximate location context for all provider errors
Even if a provider doesn't indicate a specific attribute as the cause of
a resource operation error, we know the error relates to some aspect of
the resource, so we'll include that approximate information in the result
so that we don't produce user-hostile error messages with no context
whatsoever.

Later we can hopefully refine this to place the source range on the header
of the configuration block rather than on an empty part of the body, but
that'll require some more complex rework here and so for now we'll just
accept this as an interim state so that the user can at least figure out
which resource block the error is coming from.

Martin Atkins 9ec00468f8 plugin/convert: Convert cty.PathError to diagnostics with attribute path 2018-10-16 19:14:11 -07:00
James Bardin c07ce1cd4b move conversion functions into separate package
Managing which function need to be shared between the terraform plugin
and the helper plugin without creating cycles was becoming difficult.
Move all functions related to converting between terraform and proto
type into plugin/convert.
