Martin Atkins	f058de612c	statemgr: Incorporate IntermediateStateConditionalPersister ... This interface was originally in the local backend's package because that backend is the only one that _truly_ runs Terraform operations and thus needs to negotiate how to store the intermediate state snapshots that result from them. However, putting the interface and its supporting types/functions there means that anything that wants to implement this interface needs to import the local backend package, and thus indirectly depends on the entire modules runtime, etc. We already had package stagemgr as a home for the shared stuff used by most state storage managers, and so we'll just move these symbols over there and then we can shed some internal dependencies on package local. This also severs the last dependency link between the remote state backends and the modules runtime, allowing us to shed a bunch of indirect dependencies from those remote state backends.	2 years ago
Martin Atkins	cf3bbb890f	State managers use schemarepo.Schemas instead of terraform.Schemas ... schemarepo.Schemas used to be terraform.Schemas, but its presence in the terraform package was the only reason for a state manager to need to import package terraform, so we've moved it out into its own package in the parent commit. This means that none of the state-related packages need to import package terraform any longer, and so once we've untangled some other dependencies this will curtail the number of packages in this codebase that the remote state backends transitively depend on, as part of an ongoing effort to eventually separate them from this codebase entirely.	2 years ago
Martin Atkins	1358245617	dependencies: Remove all non-legacy uses of hashicorp/go-multierror ... This functionality is now provided by the "errors" package in the standard library, so the HashiCorp-specific library is obsolete. This also removed our one direct use of github.com/pkg/errors, which we were using in a way that was totally redundant with the stdlib package errors. However, it lives on as an indirect dependency through the Consul backend's dependency on the Consul SDK, which uses that library.	2 years ago
Martin Atkins	b0b8d4aa6f	states: Only track root module output values ... For a very long time we've had an annoying discrepancy between the in-memory state model and our state snapshot format where the in-memory format stores output values for all modules whereas the snapshot format only tracks the root module output values because those are all we actually need to preserve between runs. That design wart was a result of us using the state both as an internal and an external artifact, due to having nowhere else to store the transient values of non-root module output values while Terraform Core does its work. We now have namedvals.State to internally track all of the throwaway results from named values that don't need to persist between runs, so now we'll use that for our internal work instead and reserve the states.State model only for the data that we will preserve between runs in state snapshots. The namedvals internal model isn't really designed to support enumerating all of the output values for a particular module call, but our expression evaluator currently depends on being able to do that and so we have a temporary inefficient implementation of that which just scans the entire table of values as a stopgap just to avoid this commit growing even larger than it already is. In a future commit we'll rework the evaluator to support the PartialEval mode and at the same time move the responsiblity for enumerating all of the output values into the evaluator itself, since it should be able to determine what it's expecting by analyzing the configuration rather than just by trusting that earlier evaluation has completed correctly. Because our legacy state string serialization previously included output values for all modules, some of our context tests were accidentally depending on the implementation detail of how those got stored internally. Those tests are updated here to test only the data that is a real part of Terraform Core's result, by ensuring that the relevant data appears somewhere either in a root output value or in a resource attribute.	2 years ago

Martin Atkins	783a07d9e8	build: Use Go 1.19 ... Go 1.19's "fmt" has some awareness of the new doc comment formatting conventions and adjusts the presentation of the source comments to make it clearer how godoc would interpret them. Therefore this commit includes various updates made by "go fmt" to acheve that. In line with our usual convention that we make stylistic/grammar/spelling tweaks typically only when we're "in the area" changing something else anyway, I also took this opportunity to review most of the comments that this updated to see if there were any other opportunities to improve them.	4 years ago

Brandon Croft	c33c8b013f	fix: have `terraform output` adhere to authorization w/ cloud ... Normally, `terraform output` refreshes and reads the entire state in the command package before pulling output values out of it. This doesn't give Terraform Cloud the opportunity to apply the read state outputs org permission and instead applies the read state versions permission. I decided to expand the state manager interface to provide a separate GetRootOutputValues function in order to give the cloud backend a more nuanced opportunity to fetch just the outputs. This required moving state Refresh/Read code that was previously in the command into the shared backend state as well as the filesystem state packages.	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	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
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
