Kristin Laemmert	386988cb50	Decode action blocks and action_triggers inside resource blocks. (#37030) ... * Decode action blocks and action_triggers inside resource blocks. This commit adds decoding of action and action_triggers inside terraform configuration. I added an Actions experiment as a hacky way of keeping the functionality out of main until we're ready for the alpha; this may never be an experiment but it's a handy feature flag so we don't have to do all the work in a long-lived feature branch. * remove legacy shim handling * validate that the referenced entry in actions is indeed an action	12 months ago

James Bardin	f0a64eb456	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.	5 years ago
James Bardin	53a73a8ab6	configs: add ConstraintType to config.Variable ... In order to handle optional attributes, the Variable type needs to keep track of the type constraint for decoding and conversion, as well as the concrete type for creating values and type comparison. Since the Type field is referenced throughout the codebase, and for future refactoring if the handling of optional attributes changes significantly, the constraint is now loaded into an entirely new field called ConstraintType. This prevents types containing ObjectWithOptionalAttrs from escaping the decode/conversion codepaths into the rest of the codebase.	5 years ago
Martin Atkins	1a8da65314	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.	5 years ago
Martin Atkins	e5f52e56f8	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.)	5 years ago
Martin Atkins	31349a9c3a	Move configs/ to internal/configs/ ... 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.	5 years ago
