* configs: parse provider source string during module merge
This was the smallest unit of work needed to start writing provider
source tests!
* Update configs/parser_test.go

Change ModuleInstance to Module in AbsProviderConfig, because providers
need to be handled before module expansion, and should not be used
defined inside an expanded module at all.
Renaming of the addrs type can happen later, when there's less work
in-flight around provider configuration.
Remove the requirement for most *Resource types to be a
GraphNodeModuleInstance, ensuring that they never call ctx.Path while
being evaluated. This gets rid of most of the direct need for the Path
method currently implemented by NodeResourceAbstract, leaving the
provider and schema related calls for a subsequent PR.
This adds more shimming into that node itself, but allows us to pull it
out of the config transformer, and ensure we can create the resources
correctly from the config. The shimmed address usage can then be raised
out of the abstract resource, into the expanded node types.
Using this in the same manner as NodePlannableOutput, which expands the
local values within modules. All thee output and local types are used in
both plan and apply, we may rename these to better reflect their usage
in expanding. That wait until we are certain that apply won't need any
extra machinery for handling values that aren't stored in the plan.
Unexpanded nodes can't implement GraphNodeModuleInstance (nee
GraphNodeSubPath), because they aren't aware how they have been
expanded, and may be in multiple distinct paths.
Since that means the EvalContext won't be in the correct path during the
walk, we just have to ensure that we don't use `ctx.Path()` inside Eval.
Since references are always within the scope of a single module, and we
can connect all module instance outputs for proper ordering, the
existing transformer works directly with only module paths as opposed to
module instances.
TODO: TransformApplyReferences for more precise module instance
targeting?
GraphNodeModulePath is similar to GraphNodeSubPath, except that it
returns an addrs.Module rather than an addrs.ModuleInstance. This is
used by the ReferenceTransformer to connect references, when modules may
not yet be expanded.
Because references only exist within the scope of a module, we can
connect everything knowing only the module path. If the reference is to
an expanded module instance output, we can still properly order the
reference because we'll wait for the entire module to complete
evaluation.
A typo in the config caused it to disagree with the plan on whether a
resource should be CreateBeforeDestroy, preventing it from being ordered
properly. Add the new CreateBeforeDestroy field to the test fixture
state as well for completeness.
* add Config to AttachSchemaTransformer for providerFqn lookup
* terraform: refactor ProvidedBy() to return nil when provider is not set
in config or state
We have some non-deterministic tests which flap the coverage up and down
slightly, but that should not set a failing status on PRs. This commit
sets a threshold of 0.5% coverage change to prevent this.
Something non-deterministic in the test suite is causing a coverage blip
in a line in the filesystem state manager. This commit adds a test which
specifically covers that line, which hopefully pleases the Codecov robot.
* terraform: refactor ProvidedBy() to return an addrs.ProviderConfig
interface
This refactor allows terraform to indicate whether a specific provider
configuration was found for the resource or if it is instead returning
the assumed default.
With that additional information the provider transformer can check if
there is a specific (non-default) provider FQN.
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.

* command/jsonstate: fix inconsistency with resource address
Resource addresses in state output were not including index for
instances created with for_each or count, while the index was appearing
in the plan output. This PR fixes that inconsistency, adds tests, and
updates the existing tests.
Fixes#24110
* add tests showing expected prior state resource addressing
* added example of show json state output with modules
This implies some notable changes that will have a visible impact to
end-users of official Terraform releases:
- Terraform is no longer compatible with MacOS 10.10 Yosemite, and
requires at least 10.11 El Capitan. (Relatedly, Go 1.14 is planned to be
the last release to support El Capitan, so while that remains supported
for now, it's notable that Terraform 0.13 is likely to be the last major
release of Terraform supporting it, with 0.14 likely to further require
MacOS 10.12 Sierra.)
- Terraform is no longer compatible with FreeBSD 10.x, which has reached
end-of-life. Terraform now requires FreeBSD 11.2 or later.
- Terraform now supports TLS 1.3 when it makes connections to remote
services such as backends and module registries. Although TLS 1.3 is
backward-compatible in principle, some legacy systems reportedly work
incorrectly when attempting to negotiate it. (This change does not
affect outgoing requests made by provider plugins, though they will see
a similar change in behavior once built with Go 1.13 or later.)
- Ed25519 certificates are now supported for TLS 1.2 and 1.3 connections.
- On UNIX systems where "use-vc" is set in resolv.conf, TCP will now be
used for DNS resolution. This is unlikely to cause issues in practice
because a system set up in this way can presumably already reach its
nameservers over TCP (or else other applications would misbehave), but
could potentially lead to lookup failures in unusual situations where a
system only runs Terraform, has historically had "use-vc" in its
configuration, but yet is blocked from reaching its configured
nameservers over TCP.
- Some parts of Terraform now support Unicode 12.0 when working with
strings. However, notably the Terraform Language itself continues to
use the text segmentation tables from Unicode 9.0, which means it lacks
up-to-date support for recognizing modern emoji combining forms as
single characters. (We may wish to upgrade the text segmentation tables
to Unicode 12.0 tables in a later commit, to restore consistency.)
This also includes some changes to the contents of "vendor", and
particularly to the format of vendor/modules.txt, per the changes to
vendoring in the Go 1.14 toolchain. This new syntax is activated by the
specification of "go 1.14" in the go.mod file.
Finally, the exact format of error messages from the net/http library has
changed since Go 1.12, and so a couple of our tests needed updates to
their expected error messages to match that.
