James Bardin	1ee851f256	Merge pull request #22846 from hashicorp/jbardin/evaluate-resource ... Always evaluate resources in their entirety	7 years ago
James Bardin	bfce78064b	lang/eval: more evalContext fixups ... self references do not need to be added to `managedResource`, and in fact that could cause issues later if self is allowed in contexts other than managed resources. Coalesce 2 cases in the Referenceable switch, be take the ContainingResource address of an instance beforehand.	7 years ago
Martin Atkins	39e609d5fd	vendor: switch to HCL 2.0 in the HCL repository ... Previously we were using the experimental HCL 2 repository, but now we'll shift over to the v2 import path within the main HCL repository as part of actually releasing HCL 2.0 as stable. This is a mechanical search/replace to the new import paths. It also switches to the v2.0.0 release of HCL, which includes some new code that Terraform didn't previously have but should not change any behavior that matters for Terraform's purposes. For the moment the experimental HCL2 repository is still an indirect dependency via terraform-config-inspect, so it remains in our go.sum and vendor directories for the moment. Because terraform-config-inspect uses a much smaller subset of the HCL2 functionality, this does still manage to prune the vendor directory a little. A subsequent release of terraform-config-inspect should allow us to completely remove that old repository in a future commit.	7 years ago
James Bardin	c49f976308	change lang eval to also only lookup resources ... Continue only evaluating resource at a whole and push the indexing of the resource down into the expression evaluation. The exception here is that `self` must be an instance which must be extracted from the resource. We now also add the entire resource to the context, which was previously only partially populated with the self referenced instance.	7 years ago

Martin Atkins	4d52999538	lang: EvalBlock should use ReferencesInBlock ... Previously it was calling directly to hcldec.Variables, and thus missing the special fixups we do inside ReferencesInBlock to deal with Terraform-specific concerns such as our attribute-as-blocks preprocessing.	7 years ago
Martin Atkins	479c6b2466	move "configschema" from "config" to "configs" ... The "config" package is no longer used and will be removed as part of the 0.12 release cleanup. Since configschema is part of the "new world" of configuration modelling, it makes more sense for it to live as a subdirectory of the newer "configs" package.	8 years ago
Martin Atkins	c937c06a03	terraform: ugly huge change to weave in new HCL2-oriented types ... Due to how deeply the configuration types go into Terraform Core, there isn't a great way to switch out to HCL2 gradually. As a consequence, this huge commit gets us from the old state to a _compilable_ new state, but does not yet attempt to fix any tests and has a number of known missing parts and bugs. We will continue to iterate on this in forthcoming commits, heading back towards passing tests and making Terraform fully-functional again. The three main goals here are: - Use the configuration models from the "configs" package instead of the older models in the "config" package, which is now deprecated and preserved only to help us write our migration tool. - Do expression inspection and evaluation using the functionality of the new "lang" package, instead of the Interpolator type and related functionality in the main "terraform" package. - Represent addresses of various objects using types in the addrs package, rather than hand-constructed strings. This is not critical to support the above, but was a big help during the implementation of these other points since it made it much more explicit what kind of address is expected in each context. Since our new packages are built to accommodate some future planned features that are not yet implemented (e.g. the "for_each" argument on resources, "count"/"for_each" on modules), and since there's still a fair amount of functionality still using old-style APIs, there is a moderate amount of shimming here to connect new assumptions with old, hopefully in a way that makes it easier to find and eliminate these shims later. I apologize in advance to the person who inevitably just found this huge commit while spelunking through the commit history.	8 years ago
Martin Atkins	a16ca2ec53	lang: new package for the runtime parts of the config language ... Whereas package "configs" deals with the static structure of the configuration language, this new package "lang" deals with the dynamic aspects such as expression evaluation. So far this mainly consists of populating a hcl.EvalContext that contains the values necessary to evaluate a block or an expression. There is also special handling here for dynamic block generation using the HCL "dynblock" extension, which is exposed in the public interface (rather than hiding it as an implementation detail of EvalBlock) so that the caller can then extract proper source locations for any result values using the expanded body. This also includes the beginnings of a replacement for the function table handling that currently lives in the old "config" package, but most of the functions are not yet ported and so this will expand in subsequent commits.	8 years ago
