Alisdair McDiarmid	8df065a2fe	initwd: Switch from earlyconfig to configs ... This is a mostly mechanical refactor with a handful of changes which are necessary due to the semantic difference between earlyconfig and configs. When parsing root and descendant modules in the module installer, we now check the core version requirements inline. If the Terraform version is incompatible, we drop any other module loader diagnostics. This ensures that future language additions don't clutter the output and confuse the user. We also add two new checks during the module load process: * Don't try to load a module with a `nil` source address. This is a necessary change due to the move away from earlyconfig. * Don't try to load a module with a blank name (i.e. `module ""`). Because our module loading manifest uses the stringified module path as its map key, this causes a collision with the root module, and a later panic. This is the bug which triggered this refactor in the first place.	3 years ago

Martin Atkins	bdc5f152d7	refactoring: Implied move statements can be cross-package ... Terraform uses "implied" move statements to represent the situation where it automatically handles a switch from count to no-count on a resource. Because that situation requires targeting only a specific resource instance inside a specific module instance, implied move statements are always presented as if they had been declared in the root module and then traversed through the exact module instance path to reach the target resource. However, that means they can potentially cross a module package boundary, if the changed resource belongs to an external module. Normally we prohibit that to avoid the root module depending on implementation details of the called module, but Terraform generates these implied statements based only on information in the called module and so there's no need to apply that same restriction to implied move statements, which will always have source and destination addresses belonging to the same module instance. This change therefore fixes a misbehavior where Terraform would reject an attempt to switch from no-count to count in a called module, where previously the author of the calling configuration had no recourse to fix it because the change has actually happened upstream.	4 years ago
James Bardin	75ef61c783	check for nested module index changes ... Changing only the index on a nested module will cause all nested moves to create cycles, since their full addresses will match both the From and To addresses. When building the dependency graph, check if the parent is only changing the index of the containing module, and prevent the backwards edge for the move.	4 years ago

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
Martin Atkins	83f0376673	refactoring: ApplyMoves new return type ... When we originally stubbed ApplyMoves we didn't know yet how exactly we'd be using the result, so we made it a double-indexed map allowing looking up moves in both directions. However, in practice we only actually need to look up old addresses by new addresses, and so this commit first removes the double indexing so that each move is only represented by one element in the map. We also need to describe situations where a move was blocked, because in a future commit we'll generate some warnings in those cases. Therefore ApplyMoves now returns a MoveResults object which contains both a map of changes and a map of blocks. The map of blocks isn't used yet as of this commit, but we'll use it in a later commit to produce warnings within the "terraform" package.	5 years ago
Martin Atkins	b4594551f7	refactoring: TestValidateMoves/cyclic_chain can now pass ... When originally filling out these test cases we didn't yet have the logic in place to detect chained moves and so this test couldn't succeed in spite of being correct. We now have chain-detection implemented and so consequently we can also detect cyclic chains. This commit largely just enables the original test unchanged, although it does include the text of the final error message for reporting cyclic move chains which wasn't yet finalized when we were stubbing out this test case originally.	5 years ago
Martin Atkins	aa414f3ab3	refactoring: First round of ValidateMoves rules ... This is a first pass at implementing refactoring.ValidateMoves, covering the main validation rules. This is not yet complete. A couple situations not yet covered are represented by commented test cases in TestValidateMoves, although that isn't necessarily comprehensive. We'll do a further pass of filling this out with any other subtleties before we ship this feature.	5 years ago
