Martin Atkins	86b7963bba	command: Fix tests for "terraform providers"	8 years ago
Martin Atkins	a3403f2766	terraform: Ugly huge change to weave in new State and Plan types ... Due to how often the state and plan types are referenced throughout Terraform, there isn't a great way to switch them out gradually. As a consequence, this huge commit gets us from the old world to a _compilable_ new world, but still has a large number of known test failures due to key functionality being stubbed out. The stubs here are for anything that interacts with providers, since we now need to do the follow-up work to similarly replace the old terraform.ResourceProvider interface with its replacement in the new "providers" package. That work, along with work to fix the remaining failing tests, will follow in subsequent commits. The aim here was to replace all references to terraform.State and its downstream types with states.State, terraform.Plan with plans.Plan, state.State with statemgr.State, and switch to the new implementations of the state and plan file formats. However, due to the number of times those types are used, this also ended up affecting numerous other parts of core such as terraform.Hook, the backend.Backend interface, and most of the CLI commands. Just as with 5861dbf3fc before, I apologize in advance to the person who inevitably just found this huge commit while spelunking through the commit history.	8 years ago
Martin Atkins	4ed06a9227	terraform: HCL2-flavored module dependency resolver ... For the moment this is just a lightly-adapted copy of ModuleTreeDependencies named ConfigTreeDependencies, with the goal that the two can live concurrently for the moment while not all callers are yet updated and then we can drop ModuleTreeDependencies and its helper functions altogether in a later commit. This can then be used to make "terraform init" and "terraform providers" work properly with the HCL2-powered configuration loader.	8 years ago
Martin Atkins	ebafa51723	command: Various updates for the new backend package API ... This is a rather-messy, complex change to get the "command" package building again against the new backend API that was updated for the new configuration loader. A lot of this is mechanical rewriting to the new API, but meta_config.go and meta_backend.go in particular saw some major changes to interface with the new loader APIs and to deal with the change in order of steps in the backend API.	8 years ago
Martin Atkins	9a5c865040	command: validate config as part of loading it ... Previously we required callers to separately call .Validate on the root module to determine if there were any value errors, but we did that inconsistently and would thus see crashes in some cases where later code would try to use invalid configuration as if it were valid. Now we run .Validate automatically after config loading, returning the resulting diagnostics. Since we return a diagnostics here, it's possible to return both warnings and errors. We return the loaded module even if it's invalid, so callers are free to ignore returned errors and try to work with the config anyway, though they will need to be defensive against invalid configuration themselves in that case. As a result of this, all of the commands that load configuration now need to use diagnostic printing to signal errors. For the moment this just allows us to return potentially-multiple config errors/warnings in full fidelity, but also sets us up for later when more subsystems are able to produce rich diagnostics so we can show them all together. Finally, this commit also removes some stale, commented-out code for the "legacy" (pre-0.8) graph implementation, which has not been available for some time.	8 years ago
Martin Atkins	ba0514106a	return tfdiags.Diagnostics from validation methods ... Validation is the best time to return detailed diagnostics to the user since we're much more likely to have source location information, etc than we are in later operations. This change doesn't actually add any detail to the messages yet, but it changes the interface so that we can gradually introduce more detailed diagnostics over time. While here there are some minor adjustments to some of the messages to improve their consistency with terminology we use elsewhere.	9 years ago
Radek Simko	ee30df3efd	command/providers: Enable processing of meta-parameters ... This will enable proper colouring of the output, like for other commands.	9 years ago

Martin Atkins	418a8a8bc9	command + backend: rename various API objects to "Workspace" terminology ... We're shifting terminology from "environment" to "workspace". This takes care of some of the main internal API surface that was using the old terminology, though is not intended to be entirely comprehensive and is mainly just to minimize the amount of confusion for maintainers as we continue moving towards eliminating the old terminology.	9 years ago
James Bardin	7d2d951f27	Rename VersionSet to Constraints ... VersionSet is a wrapper around version.Contraints, so rename it it as such.	9 years ago
James Bardin	718ede0636	have Meta.Backend use a Config rather than loading ... Instead of providing the a path in BackendOpts, provide a loaded *config.Config instead. This reduces the number of places where configuration is loaded.	9 years ago
Martin Atkins	3af0ecdf01	command: "terraform providers" command ... This new command prints out the tree of modules annotated with their associated required providers. The purpose of this command is to help users answer questions such as "why is this provider required?", "why is Terraform using an older version of this provider?", and "what combination of modules is creating an impossible provider version situation?" For configurations using many modules this sort of question is likely to come up a lot once we support versioned providers. As a bonus use-case, this command also shows explicitly when a provider configuration is being inherited from a parent module, to help users to understand where the configuration is coming from for each module when some child modules provide their own provider configurations.	9 years ago
