configs: allow overrides files to omit args that primary files can't Some of the fields in our config structs are either mandatory in primary files or there is a default value that we apply if absent. Unfortunately override files impose the additional constraint that we be allowed to omit required fields (which have presumably already been set in the primary files) and that we are able to distinguish between a default value and omitting a value entirely. Since most of our fields were already acceptable for override files, here we just add some new fields to deal with the few cases where special handling is required and a helper function to disable the "Required" flag on attributes in a given schema.

vendor: switch to HCL 2.0 in the HCL repository Previously we were using the experimental HCL 2 repository, but now we'll shift over to the v2 import path within the main HCL repository as part of actually releasing HCL 2.0 as stable. This is a mechanical search/replace to the new import paths. It also switches to the v2.0.0 release of HCL, which includes some new code that Terraform didn't previously have but should not change any behavior that matters for Terraform's purposes. For the moment the experimental HCL2 repository is still an indirect dependency via terraform-config-inspect, so it remains in our go.sum and vendor directories for the moment. Because terraform-config-inspect uses a much smaller subset of the HCL2 functionality, this does still manage to prune the vendor directory a little. A subsequent release of terraform-config-inspect should allow us to completely remove that old repository in a future commit.

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.

configs: allow full type constraints for variables Previously we just ported over the simple "string", "list", and "map" type hint keywords from the old loader, which exist primarily as hints to the CLI for whether to treat -var=... arguments and environment variables as literal strings or as HCL expressions. However, we've been requested before to allow more specific constraints here because it's generally better UX for a type error to be detected within an expression in a calling "module" block rather than at some point deep inside a third-party module. To allow for more specific constraints, here we use the type constraint expression syntax defined as an extension within HCL, which uses the variable and function call syntaxes to represent types rather than values, like this: - string - number - bool - list(string) - list(any) - list(map(string)) - object({id=string,name=string}) In native HCL syntax this looks like: variable "foo" { type = map(string) } In JSON, this looks like: { "variable": { "foo": { "type": "map(string)" } } } The selection of literal processing or HCL parsing of CLI-set values is now explicit in the model and separate from the type, though it's still derived from the type constraint and thus not directly controllable in configuration. Since this syntax is more complex than the keywords that replaced it, for now the simpler keywords are still supported and "list" and "map" are interpreted as list(any) and map(any) respectively, mimicking how they were interpreted by Terraform 0.11 and earlier. For the time being our documentation should continue to recommend these shorthand versions until we gain more experience with the more-specific type constraints; most users should just make use of the additional primitive type constraints this enables: bool and number. As a result of these more-complete type constraints, we can now type-check the default value at config load time, which has the nice side-effect of allowing us to produce a tailored error message if an override file produces an invalid situation; previously the result was rather confusing because the error message referred to the original definition of the variable and not the overridden parts.

configs: explicitly nullable variable values The current behavior of module input variables is to allow users to override a default by assigning `null`, which works contrary to the behavior of resource attributes, and prevents explicitly accepting a default when the input must be defined in the configuration. Add a new variable attribute called `nullable` will allow explicitly defining when a variable can be set to null or not. The current default behavior is that of `nullable=true`. Setting `nullable=false` in a variable block indicates that the variable value can never be null. This either requires a non-null input value, or a non-null default value. In the case of the latter, we also opt-in to the new behavior of a `null` input value taking the default rather than overriding it. In a future language edition where we make `nullable=false` the default, setting `nullable=true` will allow the legacy behavior of `null` overriding a default value. The only future configuration in which this would be required even if the legacy behavior were not desired is when setting an optional+nullable value. In that case `default=null` would also be needed and we could therefor imply `nullable=true` without requiring it in the configuration.

Refactoring of module source addresses and module installation It's been a long while since we gave close attention to the codepaths for module source address parsing and external module package installation. Due to their age, these codepaths often diverged from our modern practices such as representing address types in the addrs package, and encapsulating package installation details only in a particular location. In particular, this refactor makes source address parsing a separate step from module installation, which therefore makes the result of that parsing available to other Terraform subsystems which work with the configuration representation objects. This also presented the opportunity to better encapsulate our use of go-getter into a new package "getmodules" (echoing "getproviders"), which is intended to be the only part of Terraform that directly interacts with go-getter. This is largely just a refactor of the existing functionality into a new code organization, but there is one notable change in behavior here: the source address parsing now happens during configuration loading rather than module installation, which may cause errors about invalid addresses to be returned in different situations than before. That counts as backward compatible because we only promise to remain compatible with configurations that are _valid_, which means that they can be initialized, planned, and applied without any errors. This doesn't introduce any new error cases, and instead just makes a pre-existing error case be detected earlier. Our module registry client is still using its own special module address type from registry/regsrc for now, with a small shim from the new addrs.ModuleSourceRegistry type. Hopefully in a later commit we'll also rework the registry client to work with the new address type, but this commit is already big enough as it is.

configs: Handle "dynamic" blocks as special during override merging Previously we were treating "dynamic" blocks in configuration the same as any other block type when merging config bodies, so that dynamic blocks in the override would override any dynamic blocks present in the base, without considering the dynamic block type. It's more useful and intuitive for us to treat dynamic blocks as if they are instances of their given block type for the purpose of overriding. That means a foo block can be overridden by a dynamic "foo" block and vice-versa, and dynamic blocks of different types do not interact at all during overriding. This requires us to recognize dynamic blocks and treat them specially during decoding of a merged body. We leave them unexpanded here because this package is not responsible for dynamic block expansion (that happens in the sibling "lang" package) but we do decode them enough to recognize their labels so we can treat them as if they were blocks of the labelled type.

We leave them unexpanded here because this package is not responsible for dynamic block expansion (that happens in the sibling "lang" package) but we do decode them enough to recognize their labels so we can treat them as if they were blocks of the labelled type.

configs: Handle "dynamic" blocks as special during override merging Previously we were treating "dynamic" blocks in configuration the same as any other block type when merging config bodies, so that dynamic blocks in the override would override any dynamic blocks present in the base, without considering the dynamic block type. It's more useful and intuitive for us to treat dynamic blocks as if they are instances of their given block type for the purpose of overriding. That means a foo block can be overridden by a dynamic "foo" block and vice-versa, and dynamic blocks of different types do not interact at all during overriding. This requires us to recognize dynamic blocks and treat them specially during decoding of a merged body. We leave them unexpanded here because this package is not responsible for dynamic block expansion (that happens in the sibling "lang" package) but we do decode them enough to recognize their labels so we can treat them as if they were blocks of the labelled type.

configs: extend module.ProviderRequirements to include the addrs.Provider instead of just version constraints. (#23843) Renamed file.ProviderRequirements to file.RequiredProviders to match the name of the block in the configuration. file.RequiredProviders contains the contents of the file(s); module.ProviderRequirements contains the parsed and merged provider requirements. Extended decodeRequiredProvidersBlock to parse the new provider source syntax (version only, it will ignore any other attributes). Added some tests; swapped deep.Equal with cmp.Equal in the terraform/module_dependencies_test.go because deep was not catching incorrect constraints.

addrs: Rename DefaultRegistryHost to DefaultProviderRegistryHost As the comment notes, this hostname is the default for provide source addresses. We'll shortly be adding some address types to represent module source addresses too, and so we'll also have DefaultModuleRegistryHost for that situation. (They'll actually both contain the the same hostname, but that's a coincidence rather than a requirement.)
