Martin Atkins	88cb4aeea3	backendrun: Separate the types/etc for backends that support operations ... We previously had all of the types and helpers for all kinds of backends together in package backend. That kept things relatively simple, but it also meant that the majority of backends that only deal with remote state storage ended up still indirectly depending on the entire Terraform modules runtime, configuration loader, etc, etc, which brings into scope a bunch of external dependencies that the remote state backends don't really need. Since backends that support operations are a rare exception, we'll move the types and helpers for those into a separate package "backendrun", and then the main package backend can have a much more modest set of types and, more importantly, a modest set of dependencies on other packages in this codebase. This is part of an ongoing effort to reduce the exposure of Terraform Core and CLI code to the remote backends and vice-versa, so that in the long run we can more often treat them as separate for dependency maintenance purposes.	2 years ago

Martin Atkins	bee7403f3e	command/workspace_delete: Allow deleting a workspace with empty husks ... Previously we would reject attempts to delete a workspace if its state contained any resources at all, even if none of the resources had any resource instance objects associated with it. Nowadays there isn't any situation where the normal Terraform workflow will leave behind resource husks, and so this isn't as problematic as it might've been in the v0.12 era, but nonetheless what we actually care about for this check is whether there might be any remote objects that this state is tracking, and for that it's more precise to look for non-nil resource instance objects, rather than whole resources. This also includes some adjustments to our error messaging to give more information about the problem and to use terminology more consistent with how we currently talk about this situation in our documentation and elsewhere in the UI. We were also using the old State.HasResources method as part of some of our tests. I considered preserving it to avoid changing the behavior of those tests, but the new check seemed close enough to the intent of those tests that it wasn't worth maintaining this method that wouldn't be used in any main code anymore. I've therefore updated those tests to use the new HasResourceInstanceObjects method instead.	5 years ago
Martin Atkins	89b05050ec	core: Functional-style API for terraform.Context ... Previously terraform.Context was built in an unfortunate way where all of the data was provided up front in terraform.NewContext and then mutated directly by subsequent operations. That made the data flow hard to follow, commonly leading to bugs, and also meant that we were forced to take various actions too early in terraform.NewContext, rather than waiting until a more appropriate time during an operation. This (enormous) commit changes terraform.Context so that its fields are broadly just unchanging data about the execution context (current workspace name, available plugins, etc) whereas the main data Terraform works with arrives via individual method arguments and is returned in return values. Specifically, this means that terraform.Context no longer "has-a" config, state, and "planned changes", instead holding on to those only temporarily during an operation. The caller is responsible for propagating the outcome of one step into the next step so that the data flow between operations is actually visible. However, since that's a change to the main entry points in the "terraform" package, this commit also touches every file in the codebase which interacted with those APIs. Most of the noise here is in updating tests to take the same actions using the new API style, but this also affects the main-code callers in the backends and in the command package. My goal here was to refactor without changing observable behavior, but in practice there are a couple externally-visible behavior variations here that seemed okay in service of the broader goal: - The "terraform graph" command is no longer hooked directly into the core graph builders, because that's no longer part of the public API. However, I did include a couple new Context functions whose contract is to produce a UI-oriented graph, and _for now_ those continue to return the physical graph we use for those operations. There's no exported API for generating the "validate" and "eval" graphs, because neither is particularly interesting in its own right, and so "terraform graph" no longer supports those graph types. - terraform.NewContext no longer has the responsibility for collecting all of the provider schemas up front. Instead, we wait until we need them. However, that means that some of our error messages now have a slightly different shape due to unwinding through a differently-shaped call stack. As of this commit we also end up reloading the schemas multiple times in some cases, which is functionally acceptable but likely represents a performance regression. I intend to rework this to use caching, but I'm saving that for a later commit because this one is big enough already. The proximal reason for this change is to resolve the chicken/egg problem whereby there was previously no single point where we could apply "moved" statements to the previous run state before creating a plan. With this change in place, we can now do that as part of Context.Plan, prior to forking the input state into the three separate state artifacts we use during planning. However, this is at least the third project in a row where the previous API design led to piling more functionality into terraform.NewContext and then working around the incorrect order of operations that produces, so I intend that by paying the cost/risk of this large diff now we can in turn reduce the cost/risk of future projects that relate to our main workflow actions.	5 years ago
Martin Atkins	f40800b3a4	Move states/ to internal/states/ ... 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
