various: helpers for collecting necessary provider types Since schemas are required to interpret provider, resource, and provisioner attributes in configs, states, and plans, these helpers intend to make it easier to gather up the the necessary provider types in order to preload all of the needed schemas before beginning further processing. Config.ProviderTypes returns directly the list of provider types, since at this level further detail is not useful: we've not yet run the provider allocation algorithm, and so the only thing we can reliably extract here is provider types themselves. State.ProviderAddrs and Plan.ProviderAddrs each return a list of absolute provider addresses, which can then be turned into a list of provider types using the new helper providers.AddressedTypesAbs. Since we're already using configs.Config throughout core, this also updates the terraform.LoadSchemas helper to use Config.ProviderTypes to find the necessary providers, rather than implementing its own discovery logic. states.State is not yet plumbed in, so we cannot yet use State.ProviderAddrs to deal with the state but there's a TODO comment to remind us to update that in a later commit when we swap out terraform.State for states.State. A later commit will probably refactor this further so that we can easily obtain schema for the providers needed to interpret a plan too, but that is deferred here because further work is required to make core work with the new plan types first. At that point, terraform.LoadSchemas may become providers.LoadSchemas with a different interface that just accepts lists of provider and provisioner names that have been gathered by the caller using these new helpers.

internal/getproviders: A new shared model for provider requirements We've been using the models from the "moduledeps" package to represent our provider dependencies everywhere since the idea of provider dependencies was introduced in Terraform 0.10, but that model is not convenient to use for any use-case other than the "terraform providers" command that needs individual-module-level detail. To make things easier for new codepaths working with the new-style provider installer, here we introduce a new model type getproviders.Requirements which is based on the type the new installer was already taking as its input. We have new methods in the states, configs, and earlyconfig packages to produce values of this type, and a helper to merge Requirements together so we can combine config-derived and state-derived requirements together during installation. The advantage of this new model over the moduledeps one is that all of recursive module walking is done up front and we produce a simple, flat structure that is more convenient for the main use-cases of selecting providers for installation and then finding providers in the local cache to use them for other operations. This new model is _not_ suitable for implementing "terraform providers" because it does not retain module-specific requirement details. Therefore we will likely keep using moduledeps for "terraform providers" for now, and then possibly at a later time consider specializing the moduledeps logic for only what "terraform providers" needs, because it seems to be the only use-case that needs to retain that level of detail.

command/providers: Show provider requirements tree Providers can be required from multiple sources. The previous implementation of the providers sub-command displayed only a flat list of provider requirements, which made it difficult to see which modules required each provider. This commit reintroduces the tree display of provider requirements, and adds a separate output block for providers required by existing state.

Initial steps towards AbsProviderConfig/LocalProviderConfig separation (#23978) * Introduce "Local" terminology for non-absolute provider config addresses In a future change AbsProviderConfig and LocalProviderConfig are going to become two entirely distinct types, rather than Abs embedding Local as written here. This naming change is in preparation for that subsequent work, which will also include introducing a new "ProviderConfig" type that is an interface that AbsProviderConfig and LocalProviderConfig both implement. This is intended to be largely just a naming change to get started, so we can deal with all of the messy renaming. However, this did also require a slight change in modeling where the Resource.DefaultProviderConfig method has become Resource.DefaultProvider returning a Provider address directly, because this method doesn't have enough information to construct a true and accurate LocalProviderConfig -- it would need to refer to the configuration to know what this module is calling the provider it has selected. In order to leave a trail to follow for subsequent work, all of the changes here are intended to ensure that remaining work will become obvious via compile-time errors when all of the following changes happen: - The concept of "legacy" provider addresses is removed from the addrs package, including removing addrs.NewLegacyProvider and addrs.Provider.LegacyString. - addrs.AbsProviderConfig stops having addrs.LocalProviderConfig embedded in it and has an addrs.Provider and a string alias directly instead. - The provider-schema-handling parts of Terraform core are updated to work with addrs.Provider to identify providers, rather than legacy strings. In particular, there are still several codepaths here making legacy provider address assumptions (in order to limit the scope of this change) but I've made sure each one is doing something that relies on at least one of the above changes not having been made yet. * addrs: ProviderConfig interface In a (very) few special situations in the main "terraform" package we need to make runtime decisions about whether a provider config is absolute or local. We currently do that by exploiting the fact that AbsProviderConfig has LocalProviderConfig nested inside of it and so in the local case we can just ignore the wrapping AbsProviderConfig and use the embedded value. In a future change we'll be moving away from that embedding and making these two types distinct in order to represent that mapping between them requires consulting a lookup table in the configuration, and so here we introduce a new interface type ProviderConfig that can represent either AbsProviderConfig or LocalProviderConfig decided dynamically at runtime. This also includes the Config.ResolveAbsProviderAddr method that will eventually be responsible for that local-to-absolute translation, so that callers with access to the configuration can normalize to an addrs.AbsProviderConfig given a non-nil addrs.ProviderConfig. That's currently unused because existing callers are still relying on the simplistic structural transform, but we'll switch them over in a later commit. * rename LocalType to LocalName Co-authored-by: Kristin Laemmert <mildwonkey@users.noreply.github.com>

Move addrs/ to internal/addrs/ 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.

command: Providers schema shows required_providers The providers schema command is using the Config.ProviderTypes method, which had not been kept up to date with the changes to provider requirements detection made in Config.ProviderRequirements. This resulted in any currently-unused providers being omitted from the output. This commit changes the ProviderTypes method to use the same underlying logic as ProviderRequirements, which ensures that `required_providers` blocks are taken into account. Includes an integration test case to verify that this fixes the provider schemas command bug.

addrs: embed Provider in AbsProviderConfig instead of Type a large refactor to addrs.AbsProviderConfig, embedding the addrs.Provider instead of a Type string. I've added and updated tests, added some Legacy functions to support older state formats and shims, and added a normalization step when reading v4 (current) state files (not the added tests under states/statefile/roundtrip which work with both current and legacy-style AbsProviderConfig strings). The remaining 'fixme' and 'todo' comments are mostly going to be addressed in a subsequent PR and involve looking up a given local provider config's FQN.

Initial steps towards AbsProviderConfig/LocalProviderConfig separation (#23978) * Introduce "Local" terminology for non-absolute provider config addresses In a future change AbsProviderConfig and LocalProviderConfig are going to become two entirely distinct types, rather than Abs embedding Local as written here. This naming change is in preparation for that subsequent work, which will also include introducing a new "ProviderConfig" type that is an interface that AbsProviderConfig and LocalProviderConfig both implement. This is intended to be largely just a naming change to get started, so we can deal with all of the messy renaming. However, this did also require a slight change in modeling where the Resource.DefaultProviderConfig method has become Resource.DefaultProvider returning a Provider address directly, because this method doesn't have enough information to construct a true and accurate LocalProviderConfig -- it would need to refer to the configuration to know what this module is calling the provider it has selected. In order to leave a trail to follow for subsequent work, all of the changes here are intended to ensure that remaining work will become obvious via compile-time errors when all of the following changes happen: - The concept of "legacy" provider addresses is removed from the addrs package, including removing addrs.NewLegacyProvider and addrs.Provider.LegacyString. - addrs.AbsProviderConfig stops having addrs.LocalProviderConfig embedded in it and has an addrs.Provider and a string alias directly instead. - The provider-schema-handling parts of Terraform core are updated to work with addrs.Provider to identify providers, rather than legacy strings. In particular, there are still several codepaths here making legacy provider address assumptions (in order to limit the scope of this change) but I've made sure each one is doing something that relies on at least one of the above changes not having been made yet. * addrs: ProviderConfig interface In a (very) few special situations in the main "terraform" package we need to make runtime decisions about whether a provider config is absolute or local. We currently do that by exploiting the fact that AbsProviderConfig has LocalProviderConfig nested inside of it and so in the local case we can just ignore the wrapping AbsProviderConfig and use the embedded value. In a future change we'll be moving away from that embedding and making these two types distinct in order to represent that mapping between them requires consulting a lookup table in the configuration, and so here we introduce a new interface type ProviderConfig that can represent either AbsProviderConfig or LocalProviderConfig decided dynamically at runtime. This also includes the Config.ResolveAbsProviderAddr method that will eventually be responsible for that local-to-absolute translation, so that callers with access to the configuration can normalize to an addrs.AbsProviderConfig given a non-nil addrs.ProviderConfig. That's currently unused because existing callers are still relying on the simplistic structural transform, but we'll switch them over in a later commit. * rename LocalType to LocalName Co-authored-by: Kristin Laemmert <mildwonkey@users.noreply.github.com>

addrs: Stronger validation and normalization of provider namespace/type The provider FQN is becoming our primary identifier for a provider, so it's important that we are clear about the equality rules for these addresses and what characters are valid within them. We previously had a basic regex permitting ASCII letters and digits for validation and no normalization at all. We need to do at least case folding and UTF-8 normalization because these names will appear in file and directory names in case-insensitive filesystems and in repository names such as on GitHub. Since we're already using DNS-style normalization and validation rules for the hostname part, rather than defining an entirely new set of rules here we'll just treat the provider namespace and type as if they were single labels in a DNS name. Aside from some internal consistency, that also works out nicely because systems like GitHub use organization and repository names as part of hostnames (e.g. with GitHub Pages) and so tend to apply comparable constraints themselves. This introduces the possibility of names containing letters from alphabets other than the latin alphabet, and for latin letters with diacritics. That's consistent with our introduction of similar support for identifiers in the language in Terraform 0.12, and is intended to be more friendly to Terraform users throughout the world that might prefer to name their products using a different alphabet. This is also a further justification for using the DNS normalization rules: modern companies tend to choose product names that make good domain names, and now such names will be usable as Terraform provider names too.

internal/getproviders: A new shared model for provider requirements We've been using the models from the "moduledeps" package to represent our provider dependencies everywhere since the idea of provider dependencies was introduced in Terraform 0.10, but that model is not convenient to use for any use-case other than the "terraform providers" command that needs individual-module-level detail. To make things easier for new codepaths working with the new-style provider installer, here we introduce a new model type getproviders.Requirements which is based on the type the new installer was already taking as its input. We have new methods in the states, configs, and earlyconfig packages to produce values of this type, and a helper to merge Requirements together so we can combine config-derived and state-derived requirements together during installation. The advantage of this new model over the moduledeps one is that all of recursive module walking is done up front and we produce a simple, flat structure that is more convenient for the main use-cases of selecting providers for installation and then finding providers in the local cache to use them for other operations. This new model is _not_ suitable for implementing "terraform providers" because it does not retain module-specific requirement details. Therefore we will likely keep using moduledeps for "terraform providers" for now, and then possibly at a later time consider specializing the moduledeps logic for only what "terraform providers" needs, because it seems to be the only use-case that needs to retain that level of detail.

addrs: ImpliedProviderForUnqualifiedType function This encapsulates the logic for selecting an implied FQN for an unqualified type name, which could either come from a local name used in a module without specifying an explicit source for it or from the prefix of a resource type on a resource that doesn't explicitly set "provider". This replaces the previous behavior of just directly calling NewDefaultProvider everywhere so that we can use a different implication for the local name "terraform", to refer to the built-in terraform provider rather than the stale one that's on registry.terraform.io for compatibility with other Terraform versions.

command/providers: refactor with new provider types and functions The providers command has been refactored to use the modern provider types and ProviderRequirements() functions. This resulted in a breaking change to the output: it no longer outputs the providers by module and no longer prints `(inherited)` or `(from state)` to show why a provider is included. We decided that at this time it was best to stick with the existing functions and make this change, but if we get feedback from the community we will revisit. Additional tests to exercise providers in modules and providers from state have been included.

configs: Fix nested provider requirements bug In a recent PR, we changed the provider requirements code to permit per-module requirements gathering, to enhance the provider command output. This had an incorrect implementation of recursive requirements gathering for the normal case, which resulted in only depth-1 modules being inspected. This commit fixes the broken recursion and adds a grandchild module to the unit tests as test coverage. This also demanded fixing the testNestedModuleConfigFromDir helper function to cope with nested modules in test configs.

internal/getproviders: A new shared model for provider requirements We've been using the models from the "moduledeps" package to represent our provider dependencies everywhere since the idea of provider dependencies was introduced in Terraform 0.10, but that model is not convenient to use for any use-case other than the "terraform providers" command that needs individual-module-level detail. To make things easier for new codepaths working with the new-style provider installer, here we introduce a new model type getproviders.Requirements which is based on the type the new installer was already taking as its input. We have new methods in the states, configs, and earlyconfig packages to produce values of this type, and a helper to merge Requirements together so we can combine config-derived and state-derived requirements together during installation. The advantage of this new model over the moduledeps one is that all of recursive module walking is done up front and we produce a simple, flat structure that is more convenient for the main use-cases of selecting providers for installation and then finding providers in the local cache to use them for other operations. This new model is _not_ suitable for implementing "terraform providers" because it does not retain module-specific requirement details. Therefore we will likely keep using moduledeps for "terraform providers" for now, and then possibly at a later time consider specializing the moduledeps logic for only what "terraform providers" needs, because it seems to be the only use-case that needs to retain that level of detail.

cli: Fix for provider requirements in JSON plan The JSON plan output format includes a serialized, simplified version of the configuration. One component of this config is a map of provider configurations, which includes version constraints. Until now, only version constraints specified in the provider config blocks were exposed in the JSON plan output. This is a deprecated method of specifying provider versions, and the recommended use of a required_providers block resulted in the version constraints being omitted. This commit fixes this with two changes: - When processing the provider configurations from a module, output the fully-merged version constraints for the entire module, instead of any constraints set in the provider configuration block itself; - After all provider configurations are processed, iterate over the required_providers entries to ensure that any configuration-less providers are output to the JSON plan too. No changes are necessary to the structure of the JSON plan output, so this is effectively a semantic level bug fix.

The provider configuration documentation already discourages use of 'version' inside provider configuration blocks, so it only needed an extra note that it is actively deprecated.
