Sarah French	f591872699	PSS: Allow pluggable state store configuration to be stored in a plan file (#37956) ... * refactor: Rename Meta's backendState field to backendConfigState This helps with navigating ambiguity around the word backend. The new name should indicate that the value represents a `backend` block, not a more general interpretation of what a backend is. * fix: Only set backendConfigState to synthetic object if it's nil due to a lack of data. Don't change it if pluggable state storage is in use. * feat: Enable recording a state store's details in an Operation, and using that data when creating a plan file. * fix: Include provider config when writing a plan file using pluggable state storage * fix: Having `backendConfigState` be nil may be valid, but it definitely isn't valid for `stateStoreConfigState` to be nil When backendConfigState is nil it means that an implied local backend is in use, i.e. there is no backend block in the config. * test: Add integration test showing that a plan command creates a plan file with the expected state_store configuration data * refactor: Apply suggestion from @radeksimko Co-authored-by: Radek Simko <radeksimko@users.noreply.github.com> * fix: Allow panics to occur if an unexpected implementation of `backend.Backend` is encountered when managing a state store * docs: Add code comment explaining the current situation with passing backend config state to downstream logic. In future this should be simplified, either via refactoring or changes affecting the implied local backend --------- Co-authored-by: Radek Simko <radeksimko@users.noreply.github.com>	4 months ago

Alisdair McDiarmid	91d75baba1	cli: Improved error for invalid -var "foo = bar" ... When specifying variable values on the command line, name-value pairs must be joined with an equals sign, without surrounding spaces. Previously Terraform would interpret "foo = bar" as assigning the value " bar" to the variable named "foo ". This is never valid, as variable names may not include whitespace. This commit looks for this specific error and returns a diagnostic with a suggestion for correcting it. We cannot simply trim whitespace, because it is valid to write "foo= bar" to assign the value " bar" to the variable "foo", as unlikely as it seems.	4 years ago
Eng Zer Jun	fedd315275	test: use `T.TempDir` to create temporary test directory (#30803) ... This commit replaces `ioutil.TempDir` with `t.TempDir` in tests. The directory created by `t.TempDir` is automatically removed when the test and all its subtests complete. Prior to this commit, temporary directory created using `ioutil.TempDir` needs to be removed manually by calling `os.RemoveAll`, which is omitted in some tests. The error handling boilerplate e.g. defer func() { if err := os.RemoveAll(dir); err != nil { t.Fatal(err) } } is also tedious, but `t.TempDir` handles this for us nicely.

Martin Atkins	df578afd7e	backend/local: Check dependency lock consistency before any operations ... In historical versions of Terraform the responsibility to check this was inside the terraform.NewContext function, along with various other assorted concerns that made that function particularly complicated. More recently, we reduced the responsibility of the "terraform" package only to instantiating particular named plugins, assuming that its caller is responsible for selecting appropriate versions of any providers that _are_ external. However, until this commit we were just assuming that "terraform init" had correctly selected appropriate plugins and recorded them in the lock file, and so nothing was dealing with the problem of ensuring that there haven't been any changes to the lock file or config since the most recent "terraform init" which would cause us to need to re-evaluate those decisions. Part of the game here is to slightly extend the role of the dependency locks object to also carry information about a subset of provider addresses whose lock entries we're intentionally disregarding as part of the various little edge-case features we have for overridding providers: dev_overrides, "unmanaged providers", and the testing overrides in our own unit tests. This is an in-memory-only annotation, never included in the serialized plan files on disk. I had originally intended to create a new package to encapsulate all of this plugin-selection logic, including both the version constraint checking here and also the handling of the provider factory functions, but as an interim step I've just made version constraint consistency checks the responsibility of the backend/local package, which means that we'll always catch problems as part of preparing for local operations, while not imposing these additional checks on commands that _don't_ run local operations, such as "terraform apply" when in remote operations mode.	5 years ago
Martin Atkins	8d193ad268	core: Simplify and centralize plugin availability checks ... Historically the responsibility for making sure that all of the available providers are of suitable versions and match the appropriate checksums has been split rather inexplicably over multiple different layers, with some of the checks happening as late as creating a terraform.Context. We're gradually iterating towards making that all be handled in one place, but in this step we're just cleaning up some old remnants from the main "terraform" package, which is now no longer responsible for any version or checksum verification and instead just assumes it's been provided with suitable factory functions by its caller. We do still have a pre-check here to make sure that we at least have a factory function for each plugin the configuration seems to depend on, because if we don't do that up front then it ends up getting caught instead deep inside the Terraform runtime, often inside a concurrent graph walk and thus it's not deterministic which codepath will happen to catch it on a particular run. As of this commit, this actually does leave some holes in our checks: the command package is using the dependency lock file to make sure we have exactly the provider packages we expect (exact versions and checksums), which is the most crucial part, but we don't yet have any spot where we make sure that the lock file is consistent with the current configuration, and we are no longer preserving the provider checksums as part of a saved plan. Both of those will come in subsequent commits. While it's unusual to have a series of commits that briefly subtracts functionality and then adds back in equivalent functionality later, the lock file checking is the only part that's crucial for security reasons, with everything else mainly just being to give better feedback when folks seem to be using Terraform incorrectly. The other bits are therefore mostly cosmetic and okay to be absent briefly as we work towards a better design that is clearer about where that responsibility belongs.	5 years ago
Martin Atkins	343279110a	core: Graph walk loads plugin schemas opportunistically ... Previously our graph walker expected to recieve a data structure containing schemas for all of the provider and provisioner plugins used in the configuration and state. That made sense back when terraform.NewContext was responsible for loading all of the schemas before taking any other action, but it no longer has that responsiblity. Instead, we'll now make sure that the "contextPlugins" object reaches all of the locations where we need schema -- many of which already had access to that object anyway -- and then load the needed schemas just in time. The contextPlugins object memoizes schema lookups, so we can safely call it many times with the same provider address or provisioner type name and know that it'll still only load each distinct plugin once per Context object. As of this commit, the Context.Schemas method is now a public interface only and not used by logic in the "terraform" package at all. However, that does leave us in a rather tenuous situation of relying on the fact that all practical users of terraform.Context end up calling "Schemas" at some point in order to verify that we have all of the expected versions of plugins. That's a non-obvious implicit dependency, and so in subsequent commits we'll gradually move all responsibility for verifying plugin versions into the caller of terraform.NewContext, which'll heal a long-standing architectural wart whereby the caller is responsible for installing and locating the plugin executables but not for verifying that what's installed is conforming to the current configuration and dependency lock file.	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
Kristin Laemmert	096010600d	terraform: use hcl.MergeBodies instead of configs.MergeBodies for pro… (#29000) ... * terraform: use hcl.MergeBodies instead of configs.MergeBodies for provider configuration Previously, Terraform would return an error if the user supplied provider configuration via interactive input iff the configuration provided on the command line was missing any required attributes - even if those attributes were already set in config. That error came from configs.MergeBody, which was designed for overriding valid configuration. It expects that the first ("base") body has all required attributes. However in the case of interactive input for provider configuration, it is perfectly valid if either or both bodies are missing required attributes, as long as the final body has all required attributes. hcl.MergeBodies works very similarly to configs.MergeBodies, with a key difference being that it only checks that all required attributes are present after the two bodies are merged. I've updated the existing test to use interactive input vars and a schema with all required attributes. This test failed before switching from configs.MergeBodies to hcl.MergeBodies. * add a command package test that shows that we can still have providers with dynamic configuration + required + interactive input merging This test failed when buildProviderConfig still used configs.MergeBodies instead of hcl.MergeBodies	5 years ago
