* providers.Interface: huge renamification
This commit renames a handful of functions in the providers.Interface to
match changes made in protocol v6. The following commit implements this
change across the rest of the codebase; I put this in a separate commit
for ease of reviewing and will squash these together when merging.
One noteworthy detail: protocol v6 removes the config from the
ValidateProviderConfigResponse, since it's never been used. I chose to
leave that in place in the interface until we deprecate support for
protocol v5 entirely.
Note that none of these changes impact current providers using protocol
v5; the protocol is unchanged. Only the translation layer between the
proto and terraform have changed.
* terraform: improve provider config related error messages with nil
config
If there is no provider configuration present in the config at all,
errors related to missing required arguments lack source information or
even a reference to the provider in question. This PR adds more specific
error messages in three of these situations:
- ValidateProvider
- ConfigureProvider: provider.PrepareProviderConfig
- ConfigureProvider: ctx.ConfigureProvider
To test the last case I added a ConfigureProviderFn to the MockContext.
* remove newlines and let the diagnost renderer handle fit
This is a purely mechanical refactor PR: I de-exported a few more
functions which did not need to be exported in the first place, and
fixed a few outdated log outputs.
Before configuring a provider, we need to unmark the configuration
object, in case it includes any sensitive values. This is required
because configuration occurs over gRPC, which doesn't support sensitive
marks.
Core is only using the PrepareProviderConfig call for the validation
part of the method, but we should be re-validating the final config
immediately before Configure.
This change elects to not start using the PreparedConfig here, since
there is no useful reason for it at this point, and it would
introduce a functional difference between terraform releases that can be
avoided.
* remove leftover debug line
* terraform: refactor ProviderEvalTree
This PR refactors the ProviderEvalTree by folding the entire tree into
straight-through code in NodeApplyableProvider Execute (formally
EvalTree). The EvalConfigProvider functions were refactored into
NodeApplyableProvider functions (since that was the only place they were
used).
I also removed the unused node_provider_disabled code.
* revert removal of graphNodeCloseProvider EvalTree, replace with Execute
This turned out to be a big messy commit, since the way providers are
referenced is tightly coupled throughout the code. That starts to unify
how providers are referenced, using the format output node Name method.
Add a new field to the internal resource data types called
ResolvedProvider. This is set by a new setter method SetProvider when a
resource is connected to a provider during graph creation. This allows
us to later lookup the provider instance a resource is connected to,
without requiring it to have the same module path.
The InitProvider context method now takes 2 arguments, one if the
provider type and the second is the full name of the provider. While the
provider type could still be parsed from the full name, this makes it
more explicit and, and changes to the name format won't effect this
code.
