Martin Atkins	5b266dd5ca	command: Remove the experimental "terraform add" command ... We introduced this experiment to gather feedback, and the feedback we saw led to us deciding to do another round of design work before we move forward with something to meet this use-case. 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.	4 years ago
Alisdair McDiarmid	c587384dff	cli: Restore -lock and -lock-timeout init flags ... The -lock and -lock-timeout flags were removed prior to the release of 1.0 as they were thought to have no effect. This is not true in the case of state migrations when changing backends. This commit restores these flags, and adds test coverage for locking during backend state migration. Also update the help output describing other boolean flags, showing the argument as the user would type it rather than the default behavior.	4 years ago

James Bardin	c2e0d265cf	LoadModule now always returns the module ... We don't need to load the configuration twice, since configload can return the module for us.	5 years ago
James Bardin	625e768678	make sure required_version is checked before diags ... We must ensure that the terraform required_version is checked as early as possible, so that new configuration constructs don't cause init to fail without indicating the version is incompatible. The loadConfig call before the earlyconfig parsing seems to be unneeded, and we can delay that to de-tangle it from installing the modules which may have their own constraints. TODO: it seems that loadConfig should be able to handle returning the version constraints in the same manner as loadSingleModule.	5 years ago
Martin Atkins	a1a713cf28	core: Report ActionReasons when we plan to delete "orphans" ... There are a few different reasons why a resource instance tracked in the prior state might be considered an "orphan", but previously we reported them all identically in the planned changes. In order to help users understand the reason for a surprising planned delete, we'll now try to specify an additional reason for the planned deletion, covering all of the main reasons why that could happen. This commit only introduces the new detail to the plans.Changes result, though it also incidentally exposes it as part of the JSON plan result in order to keep that working without returning errors in these new cases. We'll expose this information in the human-oriented UI output in a subsequent commit.	5 years ago
Chris Arcand	60bc7aa05d	command: Auto-select single workspace if necessary ... When initializing a backend, if the currently selected workspace does not exist, the user is prompted to select from the list of workspaces the backend provides. Instead, we should automatically select the only workspace available _if_ that's all that's there. Although with being a nice bit of polish, this enables future improvments with Terraform Cloud in potentially removing the implicit depenency on always using the 'default' workspace when the current configuration is mapped to a single TFC workspace.	5 years ago
Alisdair McDiarmid	78c4a8c461	json-output: Previous address for resource changes ... Configuration-driven moves are represented in the plan file by setting the resource's `PrevRunAddr` to a different value than its `Addr`. For JSON plan output, we here add a new field to resource changes, `previous_address`, which is present and non-empty only if the resource is planned to be moved. Like the CLI UI, refresh-only plans will include move-only changes in the resource drift JSON output. In normal plan mode, these are elided to avoid redundancy with planned changes.	5 years ago
Martin Atkins	f0034beb33	core: refactoring.ImpliedMoveStatements replaces NodeCountBoundary ... Going back a long time we've had a special magic behavior which tries to recognize a situation where a module author either added or removed the "count" argument from a resource that already has instances, and to silently rename the zeroth or no-key instance so that we don't plan to destroy and recreate the associated object. Now we have a more general idea of "move statements", and specifically the idea of "implied" move statements which replicates the same heuristic we used to use for this behavior, we can treat this magic renaming rule as just another "move statement", special only in that Terraform generates it automatically rather than it being written out explicitly in the configuration. In return for wiring that in, we can now remove altogether the NodeCountBoundary graph node type and its associated graph transformer, CountBoundaryTransformer. We handle moves as a preprocessing step before building the plan graph, so we no longer need to include any special nodes in the graph to deal with that situation. The test updates here are mainly for the graph builders themselves, to acknowledge that indeed we're no longer inserting the NodeCountBoundary vertices. The vertices that NodeCountBoundary previously depended on now become dependencies of the special "root" vertex, although in many cases here we don't see that explicitly because of the transitive reduction algorithm, which notices when there's already an equivalent indirect dependency chain and removes the redundant edge. We already have plenty of test coverage for these "count boundary" cases in the context tests whose names start with TestContext2Plan_count and TestContext2Apply_resourceCount, all of which continued to pass here without any modification and so are not visible in the diff. The test functions particularly relevant to this situation are: - TestContext2Plan_countIncreaseFromNotSet - TestContext2Plan_countDecreaseToOne - TestContext2Plan_countOneIndex - TestContext2Apply_countDecreaseToOneCorrupted The last of those in particular deals with the situation where we have both a no-key instance _and_ a zero-key instance in the prior state, which is interesting here because to exercises an intentional interaction between refactoring.ImpliedMoveStatements and refactoring.ApplyMoves, where we intentionally generate an implied move statement that produces a collision and then expect ApplyMoves to deal with it in the same way as it would deal with all other collisions, and thus ensure we handle both the explicit and implied collisions in the same way. This does affect some UI-level tests, because a nice side-effect of this new treatment of this old feature is that we can now report explicitly in the UI that we're assigning new addresses to these objects, whereas before we just said nothing and hoped the user would just guess what had happened and why they therefore weren't seeing a diff. The backend/local plan tests actually had a pre-existing bug where they were using a state with a different instance key than the config called for but getting away with it because we'd previously silently fix it up. That's still fixed up, but now done with an explicit mention in the UI and so I made the state consistent with the configuration here so that the tests would be able to recognize _real_ differences where present, as opposed to the errant difference caused by that inconsistency.	5 years ago

Martin Atkins	383bbdeebc	Upgrade to Go 1.17 ... This includes the addition of the new "//go:build" comment form in addition to the legacy "// +build" notation, as produced by gofmt to ensure consistent behavior between Go versions. The new directives are all equivalent to what was present before, so there's no change in behavior. Go 1.17 continues to use the Unicode 13 tables as in Go 1.16, so this upgrade does not require also upgrading our Unicode-related dependencies. This upgrade includes the following breaking changes which will also appear as breaking changes for Terraform users, but that are consistent with the Terraform v1.0 compatibility promises. - On MacOS, Terraform now requires macOS 10.13 High Sierra or later. This upgrade also includes the following breaking changes which will appear as breaking changes for Terraform users that are inconsistent with our compatibility promises, but have justified exceptions as follows: - cidrsubnet, cidrhost, and cidrnetmask will now reject IPv4 CIDR addresses whose decimal components have leading zeros, where previously they would just silently ignore those leading zeros. This is a security-motivated exception to our compatibility promises, because some external systems interpret zero-prefixed octets as octal numbers rather than decimal, and thus the previous lenient parsing could lead to a different interpretation of the address between systems, and thus potentially allow bypassing policy when configuring firewall rules etc. This upgrade also includes the following breaking changes which could _potentially_ appear as breaking changes for Terraform users, but that do not in practice for the reasons given: - The Go net/url package no longer allows query strings with pairs separated by semicolons instead of ampersands. This primarily affects HTTP servers written in Go, and Terraform includes a special temporary HTTP server as part of its implementation of OAuth for "terraform login", but that server only needs to accept URLs created by Terraform itself and Terraform does not generate any URLs that would be rejected.	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
Alisdair McDiarmid	3326ab7dae	json-output: Omit unchanged resource_drift entries ... Previously, if any resources were found to have drifted, the JSON plan output would include a drift entry for every resource in state. This commit aligns the JSON plan output with the CLI UI, and only includes those resources where the old value does not equal the new value---i.e. drift has been detected. Also fixes a bug where the "address" field was missing from the drift output, and adds some test coverage.	5 years ago
Kristin Laemmert	583859e510	commands: `terraform add` (#28874) ... * command: new command, terraform add, generates resource templates terraform add ADDRESS generates a resource configuration template with all required (and optionally optional) attributes set to null. This can optionally also pre-populate nonsesitive attributes with values from an existing resource of the same type in state (sensitive vals will be populated with null and a comment indicating sensitivity) * website: terraform add documentation	5 years ago
Kristin Laemmert	329585d07d	jsonconfig: properly unwind and enumerate references (#28884) ... The "references" included in the expression representation now properly unwrap for each traversal step, to match what was documented.	5 years ago
Kristin Laemmert	ac03d35997	jsonplan and jsonstate: include sensitive_values in state representations (#28889) ... * jsonplan and jsonstate: include sensitive_values in state representations A sensitive_values field has been added to the resource in state and planned values which is a map of all sensitive attributes with the values set to true. It wasn't entirely clear to me if the values in state would suffice, or if we also need to consult the schema - I believe that this is sufficient for state files written since v0.15, and if that's incorrect or insufficient, I'll add in the provider schema check as well. I also updated the documentation, and, since we've considered this before, bumped the FormatVersions for both jsonstate and jsonplan.	5 years ago
Kristin Laemmert	649095c602	providers subcommand tests (#28744) ... * getproviders ParsePlatform: add check for invalid platform strings with too many parts The existing logic would not catch things like a platform string containing multiple underscores. I've added an explicit check for exactly 2 parts and some basic tests to prove it. * command/providers-lock: add tests This commit adds some simple tests for the providers lock command. While adding this test I noticed that there was a mis-copied error message, so I replaced that with a more specific message. I also added .terraform.lock.hcl to our gitignore for hopefully obvious reasons. getproviders.ParsePlatform: use parts in place of slice range, since it's available * command: Providers mirror tests The providers mirror command is already well tested in e2e tests, so this includes only the most absolutely basic test case.	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
