Martin Atkins	36c4d4c241	core and backend: remove redundant handling of default variable values ... Previously we had three different layers all thinking they were responsible for substituting a default value for an unset root module variable: - the local backend, via logic in backend.ParseVariableValues - the context.Plan function (and other similar functions) trying to preprocess the input variables using terraform.mergeDefaultInputVariableValues . - the newer prepareFinalInputVariableValue, which aims to centralize all of the variable preparation logic so it can be common to both root and child module variables. The second of these was also trying to handle type constraint checking, which is also the responsibility of the central function and not something we need to handle so early. Only the last of these consistently handles both root and child module variables, and so is the one we ought to keep. The others are now redundant and are causing prepareFinalInputVariableValue to get a slightly corrupted view of the caller's chosen variable values. To rectify that, here we remove the two redundant layers altogether and have unset root variables pass through as cty.NilVal all the way to the central prepareFinalInputVariableValue function, which will then handle them in a suitable way which properly respects the "nullable" setting. This commit includes some test changes in the terraform package to make those tests no longer rely on the mergeDefaultInputVariableValues logic we've removed, and to instead explicitly set cty.NilVal for all unset variables to comply with our intended contract for PlanOpts.SetVariables, and similar. (This is so that we can more easily catch bugs in callers where they _don't_ correctly handle input variables; it allows us to distinguish between the caller explicitly marking a variable as unset vs. not describing it at all, where the latter is a bug in the caller.)	4 years ago

Martin Atkins	b802db75d7	build: Build and run e2etest as part of the release build pipeline ... This uses the decoupled build and run strategy to run the e2etests so that we can arrange to run the tests against the real release packages produced elsewhere in this workflow, rather than ones generated just in time by the test harness. The modifications to make-archive.sh here make it more consistent with its originally-intended purpose of producing a harness for testing "real" release executables. Our earlier compromise of making it include its own terraform executable came from a desire to use that script as part of manual cross-platform testing when we weren't yet set up to support automation of those tests as we're doing here. That does mean, however, that the terraform-e2etest package content must be combined with content from a terraform release package in order to produce a valid contest for running the tests. We use a single job to cross-compile the test harness for all of the supported platforms, because that build is relatively fast and so not worth the overhead of matrix build, but then use a matrix build to actually run the tests so that we can run them in a worker matching the target platform. We currently have access only to amd64 (x64) runners in GitHub Actions and so for the moment this process is limited only to the subset of our supported platforms which use that architecture.	4 years ago
Alisdair McDiarmid	535da4ebc7	Merge pull request #30205 from hashicorp/alisdair/fix-show-plan-against-non-default-state ... command/show: Disable plan state lineage checks	4 years ago
Martin Atkins	23395a1022	providercache: Discard lock entries for unused providers ... Previously we would only ever add new lock entries or update existing ones. However, it's possible that over time a module may _cease_ using a particular provider, at which point we ought to remove it from the lock file so that operations won't fail when seeing that the provider cache directory is inconsistent with the lock file. Now the provider installer (EnsureProviderVersions) will remove any lock file entries that relate to providers not included in the given requirements, which therefore makes the resulting lock file properly match the set of packages the installer wrote into the cache. This does potentially mean that someone could inadvertently defeat the lock by removing a provider dependency, running "terraform init", then undoing that removal, and finally running "terraform init" again. However, that seems relatively unlikely compared to the likelihood of removing a provider and keeping it removed, and in the event it _did_ happen the changes to the lock entry for that provider would be visible in the diff of the provider lock file as usual, and so could be noticed in code review just as for any other change to dependencies.	4 years ago
Alisdair McDiarmid	768741c0f7	command/show: Disable plan state lineage checks ... When showing a saved plan, we do not need to check the state lineage against current state, because the plan cannot be applied. This is relevant when plan and apply specify a `-state` argument to choose a non-default state file. In this case, the stored prior state in the plan will not match the default state file, so a lineage check will always error.	4 years ago

Chris Arcand	98978b3853	command/meta_backend: Allow the remote backend to have no workspaces [again] ... A regression introduced in d72a413ef8 The comment explains, but TLDR: The remote backend actually *depended* on being able to write it's backend state even though an 'error' occurred (no workspaces).	4 years ago
Martin Atkins	096cddb4b7	command/format: Limitation of plans.ResourceInstanceDeleteBecauseNoModule ... This is an explicit technical debt note that our plan renderer isn't able to give a fully-specific hint in this particular case of deletion reason. This reason code means that at least one of the module instance keys in the resource's module path doesn't match an instance declared in the configuration, but the plan data structure doesn't retain enough information to know which is the first step in the path which refers to a missing instance, and so we just always return the whole thing. This would be confusing if we return module.foo[0].module.bar not being in the configuration as a result of module.foo not using "count"; it would be better to say "module.foo[0] is not in the configuration" instead. It would be most ideal to handle all of the different situations that ResourceInstanceDeleteBecauseWrongRepetition's rendering does, so that we can go further and explain exactly _why_ that module instance isn't declared anymore. We can do neither of those things today because only the Terraform Core "expander" component knows that information, and we've discarded that by the time we get to rendering a plan. To fix this one day would require preserving in the plan information about which module instances are declared, as a separate sidecar data structure from which resource instances we're taking actions on, and then using that to identify which step in addr.Module here first selects an invalid instance.	4 years ago

Barrett Clark	e08a02e7bf	Fixes Issue #29959, Apply w/o init error message ... When going from a local backend to Terraform Cloud, if you skip the `terraform init` and run `terraform apply` this will give the user more clear instructions.	4 years ago
Luces Huayhuaca	d72a413ef8	command/meta_backend: Prompt to select workspace before saving backend config (#29945) ... When terraform detects that a user has no workspaces that map to their current configuration, it will prompt the user to create a new workspace and enter a value name. If the user ignores the prompt and exits it, the legacy backend (terraform.tfstate) will be left in a awkward state: 1. This saved backend config will show a diff for the JSON attributes "serial", "tags" and "hash" 2. "Terraform workspace list" will show an empty list 3. "Terraform apply" will run successfully using the previous workspace, from the previous config, not the one from the current saved backend config 4. The cloud config is not reflective of the current working directory Solution: If the user exits the prompt, the saved backend config should not be updated because they did not select a new workspace. They are back at the beginning where they are force to re run the init cmd again before proceeding with new changes.	4 years ago

Barrett Clark	419676cb69	Cloud integration requires input for migrations ... We cannot programmatically migrate workspaces to Terraform Cloud without prompts, so `-input=false` should not be allowed in those cases. There are 4 scenarios where we need input from a user to complete migrating workspaces to Terraform Cloud. 1.) Migrate from a single local workspace to Terraform Cloud * Terraform config for a local backend. Implicit local (no backend specified) is fine. * `terraform init` and `terraform apply` * Change the Terraform config to use the cloud block * `terraform init -input=false` * You should now see an error message 2.) Migrate from a remote backend with a prefix to Terraform Cloud with tags * Create a workspace in Terraform Cloud manually. The name should include a prefix, like "app-one" * Have the terraform config use `backend "remote"` with a prefix set to "app-" * `terraform init` and `terraform apply` * Update the Terraform config to use a cloud block with `tags = ["app"]`. There should not be a prefix defined in the config now. * `terraform init -input=false` * You should now see an error message 3.) Migrate from multiple local workspaces to a single Terraform Cloud workspace * Create one or many local workspaces * `terraform init` and `terraform apply` in each * Change the Terraform config to use the cloud block * `terraform init -input=false` * You should now see an error message 4.) Migrate to Terraform Cloud and ask for a workspace name * Create several local workspaces * `terraform init` and `terraform apply` in each * Change the Terraform config to use the cloud block with tags * `terraform init -input=false` * You should now see an error message	4 years ago
Luces Huayhuaca	f63b6198ca	Create a function for logic that assigns value to initReason var after changing backend configuration (#29967) ... * Create a function for logic that assigns value to initReason var after changing backend configuration Create func determineInitReason() for logic block that assigns value to initReason var after changing backend/cloud configuration block or migrating to a different type of backend configuration. Also clarify 'cloud' configuration block message to say 'Terraform Cloud configuration block has changed' instead of 'Terraform Cloud configuration has changed'.	4 years ago

Chris Arcand	a0c7c1dc8d	command/init: Adjust init help output ... Some of the wording here needed adjusting with the change that backends largely reflect state snapshot storage (removing 'enhanced' designation), and that a 'backend' is not necessarily always present.	4 years ago
Chris Arcand	33d7c1e6d6	command/init: Add -cloud alias (of -backend) ... This fixes an issue where a user could not disable initialization of the 'cloud' configuration block (As is possible with -backend=false), as well as add some syntactic sugar around -backend by adding a mutually exclusive -cloud alias.	4 years ago

Martin Atkins	7d6d31eff8	command/init: Skip redundant state migration prompt in Cloud mode ... The specialized Terraform Cloud migration process asks right up top whether the user wants to migrate state, because there are various other questions contingent on that answer. Therefore we ought to just honor their earlier answer when we get to the point of actually doing the state migration, rather than prompting again. This is tricky because we're otherwise just reusing a codepath that's common to both modes. Hopefully we can find a better way to do this in a later commit, but for the moment our main motivation is minimizing risk to the very next release.	4 years ago
Martin Atkins	bac59d2480	command/init: Be explicit that some options are not relevant for Cloud ... There are a few command line options for "terraform init" which are only relevant when working with traditional backends, with the Cloud integration previously just mostly ignoring them, or sometimes misbehaving slightly due to them creating an unreasonable situation. Now we'll catch these and return explicit errors, in order to be clear that these options are not needed nor supported in Cloud mode.	4 years ago
Barrett Clark	a146a2746e	Add clarifying commend and e2e test ... This pull request focuses on removing the prompt to rename the default workspace when it is empty. Functionality already exists to not migrate an empty workspace. This commit adds some clarifying language in the comment where we do the evaluation to know whether to ask for a new name or not. I also added an end to end test, which I should have added to begin with.	4 years ago
Barrett Clark	a9eb62d692	Cloud: Migrate empty default workspace prompt ... Given: You have multiple explicit local workspaces, and the `default` workspace is empty.

kmoe	40ec62c139	command: make module installation interruptible ... Earlier work to make "terraform init" interruptible made the getproviders package context-aware in order to allow provider installation to be cancelled. Here we make a similar change for module installation, which is now also cancellable with SIGINT. This involves plumbing context through initwd and getmodules. Functions which can make network requests now include a context parameter whose cancellation cancels those requests. Since the module installation code is shared, "terraform get" is now also interruptible during module installation.	5 years ago

Chris Arcand	779c958fbf	cloud: Add streamlined 'remote' backend state migration path ... For Terraform Cloud users using the 'remote' backend, the existing 'pattern' prompt should work just fine - but because their workspaces are already present in TFC, the 'migration' here is really just realigning their local workspaces with Terraform Cloud. Instead of forcing users to do the mental gymnastics of what it means to migrate from 'prefix' - and because their remote workspaces probably already exist and already conform to Terraform Cloud's naming concerns - streamline the process for them and calculate the necessary pattern to migrate as-is, without any user intervention necessary.	5 years ago

Chris Arcand	f04ea2bd3d	Merge pull request #29860 from hashicorp/fix-init-after-error-take-two ... command: Update backend hash value only after a successful migration	5 years ago
Chris Arcand	7c0c2e952f	command: Don't always update backend hash when fetching the saved backend ... The Meta.backend_C_r_S_unchanged() method was sadly a bit of a mess. It seems to have originally been used as a method to be called when the backend is not changing, with an extra assumption that if the configured backend's hash doesn't match the one in state, surely the hash should just be updated as an option might have been moved to command line flags. However, this function was used throughout this file as 'the method to load the initialized (but not necessarily configured) backend', regardless of whether or not it is the same (unchanged). This is in addition to Meta.backendFromState(), which is used to load the same thing except in the main codepath of 'init -backend=false'. These changes separate the concerns of backend_C_r_S_unchanged() by 1) Fetching the saved backend (savedBackend()) 2) Updating the hash value in the backend cache when appropriate (either by leaving it to the caller to do themselves or by calling updateSavedupdateSavedBackendHash()) This allows migration codepaths to *not* update the hash value until after a migration has successfully taken place.	5 years ago

Billy Keyes	52ca30273f	command/format: improve list nested attribute rendering (#29827) ... * command/format: fix list nested attr diff rendering Previously, diffs only rendered correctly if all changed elements appeared before all unchanged elements. Once an unchanged element was found, all remaining elements were skipped. This usually led to the output being an empty list with a weird amount of space between the brackets. * command/format: improve list nested attr rendering This makes several changes that make diffs for lists clearer and more consistent: * Separate items with brackets instead of only new lines. This better matches the input syntax and avoids confusion from the first and last brackets implying there is a single item. * Render an action symbol for each element of the list * Use the correct action symbol for new and deleted items * Fix the alignment of opening and closing brackets I also refactored the structure so it is similar to the set and map cases to minimize duplication of the new prints. * Fix re-use of blockBodyDiffResult struct	5 years ago
Nick Fagerlund	02e62c9851	Cloud: Init without erroring when no workspaces match the `tags` (#29835) ... Previously, `terraform init` was throwing an error if you configured the cloud block with `tags` and there weren't any tagged workspaces yet. Confusing and alienating, since that that's a fairly normal situation! Basically TFC was handling an empty list of workspaces worse than other backends, because it doesn't support an unnamed default workspace. This commit catches that condition during `Meta.selectBackend()` and asks the user to pick a name for their first tagged workspace. If they cancel out, we still error, but if we know what name they want, we can handle it the same way as a nonexistent workspace specified in `name` -- just pass it to `Meta.SetWorkspace()`, and let the workspace get implicitly created when `InitCommand.Run()` eventually calls `StateMgr()`.	5 years ago
Martin Atkins	94cbc8fb5d	experiments: config_driven_move has concluded ... Based on feedback during earlier alpha releases, we've decided to move forward with the current design for the first phase of config-driven refactoring.

The other changes here are all just updating test fixtures to no longer declare that they are using experimental features.	5 years ago
Chris Arcand	511afcd43a	command: Adjust skipping of resource counts for any remote implementation ...

Barrett Clark	ab304d831f	Found another path to backend init error ... There are actually a few different ways to get to this message. 1. Blank state — no previous terraform applied. Start with a cloud block. 1. Implicit local — start with no backend specified. This actually goes through the same code execution path as the first scenario. 1. Explicit local — start with a backend local block that has been applied, then change from the local backend to a cloud block. This will recognize the state, and is a different path through the code in the meta backend. This commit handles the last case. The messaging has also been tweaked. End to end test included as well.	5 years ago

Alisdair McDiarmid	d42d83572b	cli: Fix backend init failure with deleted cache ... When an explicit backend is configured with a configuration which has not yet been initialized, running `terraform init` performs a state migration to fetch the remotely stored state in order to operate on it. Like the previous bug introduced by the recent provider diagnostics change, this code path was not correctly configured to enable init mode for the backend, which resulted in a fatal error during init when the cache dir is deleted. Setting the `Init` backend option allows this code path to continue without error when first initializing the backend for state migration. The new e2e test fails without this change.	5 years ago
Alisdair McDiarmid	1729431520	backend/remote: Fix version check when migrating ... When migrating state to an existing Terraform Cloud workspace using the remote backend, we check the remote version is compatible with the local one by default. This commit fixes two bugs in this code: - If using the "name" strategy for the remote backend, the list of destination workspaces is empty. This resulted in no version checking of the remote workspace, and we fell back to the string equality check. - The user-specified CLI flag `-ignore-remote-version` was not being applied for the state migration version checking.	5 years ago
Alisdair McDiarmid	39de3ebec7	cli: Fix init failure with deleted cache ... The init command needs to initialize a backend, in order to access state, in turn to derive provider requirements from state. The backend initialization step requires building provider factories, which previously would fail if a lockfile was present without a corresponding local provider cache. This commit ensures that in this situation only, errors with the provider factories are temporarily ignored. This allows us to continue to initialize the backend, fetch providers, and then report any errors as necessary.	5 years ago
Alisdair McDiarmid	1190b95fe2	command/e2etest: Ensure init fixes missing cache ...

Martin Atkins	5b266dd5ca	command: Remove the experimental "terraform add" command ...

In addition to being experimental, this has only been included in alpha releases so far, and so on both counts it is not protected by the Terraform v1.0 Compatibility Promises.	5 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	01b22f4b76	command/e2etest: TestProviderTampering ... We have various mechanisms that aim to ensure that the installed provider plugins are consistent with the lock file and that the lock file is consistent with the provider requirements, and we do have existing unit tests for them, but all of those cases mock our fake out at least part of the process and in the past that's caused us to miss usability regressions, where we still catch the error but do so at the wrong layer and thus generate error message lacking useful additional context. Here we'll add some new end-to-end tests to supplement the existing unit tests, making sure things work as expected when we assemble the system together as we would in a release. These tests cover a number of different ways in which the plugin selections can grow inconsistent. These new tests all run only when we're in a context where we're allowed to access the network, because they exercise the real plugin installer codepath. We could technically build this to use a local filesystem mirror or other such override to avoid that, but the point here is to make sure we see the expected behavior in the main case, and so it's worth the small additional cost of downloading the null provider from the real registry.	5 years ago
Martin Atkins	d09510a8fb	command: Early error message for missing cache entries of locked providers ... In the original incarnation of Meta.providerFactories we were returning into a Meta.contextOpts whose signature didn't allow it to return an error directly, and so we had compromised by making the provider factory functions themselves return errors once called. Subsequent work made Meta.contextOpts need to return an error anyway, but at the time we neglected to update our handling of the providerFactories result, having it still defer the error handling until we finally instantiate a provider. Although that did ultimately get the expected result anyway, the error ended up being reported from deep in the guts of a Terraform Core graph walk, in whichever concurrently-visited graph node happened to try to instantiate the plugin first. This meant that the exact phrasing of the error message would vary between runs and the reporting codepath didn't have enough context to given an actionable suggestion on how to proceed. In this commit we make Meta.contextOpts pass through directly any error that Meta.providerFactories produces, and then make Meta.providerFactories produce a special error type so that Meta.Backend can ultimately return a user-friendly diagnostic message containing a specific suggestion to run "terraform init", along with a short explanation of what a provider plugin is. The reliance here on an implied contract between two functions that are not directly connected in the callstack is non-ideal, and so hopefully we'll revisit this further in future work on the overall architecture of the CLI layer. To try to make this robust in the meantime though, I wrote it to use the errors.As function to potentially unwrap a wrapped version of our special error type, in case one of the intervening layers is changed at some point to wrap the downstream error before returning it.	5 years ago
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	6a98e4720c	plans/planfile: Create takes most arguments via a struct type ... Previously the planfile.Create function had accumulated probably already too many positional arguments, and I'm intending to add another one in a subsequent commit and so this is preparation to make the callsites more readable (subjectively) and make it clearer how we can extend this function's arguments to include further components in a plan file. There's no difference in observable functionality here. This is just passing the same set of arguments in a slightly different way.	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
