Kristin Laemmert	e3416124cc	addrs: replace "Type string" with "Type Provider" in ProviderConfig ... * huge change to weave new addrs.Provider into addrs.ProviderConfig * terraform: do not include an empty string in the returned Providers / Provisioners - Fixed a minor bug where results included an extra empty string	6 years ago
Kristin Laemmert	9891d0354a	providers: use addrs.Provider as map keys for provider.Factory (#23548) ... * terraform/context: use new addrs.Provider as map key in provider factories * added NewLegacyProviderType and LegacyString funcs to make it explicit that these are temporary placeholders This PR introduces a new concept, provider fully-qualified name (FQN), encapsulated by the `addrs.Provider` struct.	6 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.	6 years ago

Martin Atkins	86c02d5c35	command: "terraform init" can partially initialize for 0.12upgrade ... There are a few constructs from 0.11 and prior that cause 0.12 parsing to fail altogether, which previously created a chicken/egg problem because we need to install the providers in order to run "terraform 0.12upgrade" and thus fix the problem. This changes "terraform init" to use the new "early configuration" loader for module and provider installation. This is built on the more permissive parser in the terraform-config-inspect package, and so it allows us to read out the top-level blocks from the configuration while accepting legacy HCL syntax. In the long run this will let us do version compatibility detection before attempting a "real" config load, giving us better error messages for any future syntax additions, but in the short term the key thing is that it allows us to install the dependencies even if the configuration isn't fully valid. Because backend init still requires full configuration, this introduces a new mode of terraform init where it detects heuristically if it seems like we need to do a configuration upgrade and does a partial init if so, before finally directing the user to run "terraform 0.12upgrade" before running any other commands. The heuristic here is based on two assumptions: - If the "early" loader finds no errors but the normal loader does, the configuration is likely to be valid for Terraform 0.11 but not 0.12. - If there's already a version constraint in the configuration that excludes Terraform versions prior to v0.12 then the configuration is probably _already_ upgraded and so it's just a normal syntax error, even if the early loader didn't detect it. Once the upgrade process is removed in 0.13.0 (users will be required to go stepwise 0.11 -> 0.12 -> 0.13 to upgrade after that), some of this can be simplified to remove that special mode, but the idea of doing the dependency version checks against the liberal parser will remain valuable to increase our chances of reporting version-based incompatibilities rather than syntax errors as we add new features in future.	7 years ago

Martin Atkins	30b7040e95	core: Validate module references ... Previously we were making an invalid assumption in evaluating module call references (like module.foo) that the module must exist, which is incorrect for that particular case because it's a reference to a child module, not to an object within the current module. However, now that we have the mechanism for static validation of references, we'll deal with this one there so it can be caught sooner. That then makes the original assumption valid, though for a different reason. This is verified by two new context tests for validation: - TestContext2Validate_invalidModuleRef - TestContext2Validate_invalidModuleOutputRef	7 years ago
Martin Atkins	3b49028b77	core: Static-validate resource references against schemas ... In the initial move to HCL2 we started relying only on full expression evaluation to catch attribute errors, but that's not sufficient for resource attributes in practice because during validation we can't know yet whether a resource reference evaluates to a single object or to a list of objects (if count is set). To address this, here we reinstate some static validation of resource references by analyzing directly the reference objects, disregarding any instance index if present, and produce errors if the remaining subsequent traversal steps do not correspond to items within the resource type schema. This also allows us to produce some more specialized error messages for certain situations. In particular, we can recognize a reference like aws_instance.foo.count, which in 0.11 and prior was a weird special case for determining the count value of a resource block, and offer a helpful error showing the new length(aws_instance.foo) usage pattern. This eventually delegates to the static traversal validation logic that was added to the configschema package in a previous commit, which also includes some specialized error messages that distinguish between attributes and block types in the schema so that the errors relate more directly to constructs the user can see in the configuration. In future we could potentially move more of the checks from the dynamic schema construction step to the static validation step, but resources are the reference type that most needs this immediately due to the ambiguity caused by the instance indexing syntax. We can safely refactor other reference types to be statically validated in later releases. This is verified by two pre-existing context validate tests which we temporarily disabled during earlier work (now re-enabled) and also by a new validate test aimed specifically at the special case for the "count" attribute.	7 years ago
Martin Atkins	ece8b6e734	repl: Fix tests ... The test suite was not updated to deal with the new assumptions of the HCL2-based expression evaluator, which requires configuration to exist as well as state. Therefore we add a simple configuration fixture to have it validate expressions against. This also includes updates to expect the different error messages that the new evaluator produces.	7 years ago

Martin Atkins	5ff35c1a9a	repl: Make tests compile and execute without panics ... There are still some errors left, because our expression evaluator now does more validation than before and so we'll need to (in a subsequent commit) actually use a fixture configuration for these tests so that the validations will allow the expressions to be validated.	7 years ago
Martin Atkins	f085af4ba6	command: update "terraform console" for HCL2 ... This now uses the HCL2 parser and evaluator APIs and evaluates in terms of a new-style *lang.Scope, rather than the old terraform.Interpolator type that is no longer functional. The Context.Eval method used here behaves differently than the Context.Interpolater method used previously: it performs a graph walk to populate transient values such as input variables, local values, and output values, and produces its scope in terms of the result of that graph walk. Because of this, it is a lot more robust than the prior method when asked to resolve references other than those that are persisted in the state.	7 years ago
Martin Atkins	5659128126	repl: fix formatting of list and map values ... The indent function was stripping out newlines, causing multi-element lists and maps to be rendered incorrectly. We were also not quoting strings in these nested structures, leading to weird behavior if any expression punctuation or newlines were present in these strings. This part of Terraform will get a more serious overhaul as part of switching to the new parser/interpreter implementation but this is a tactical fix to make the results of this command more usable in the short term.	8 years ago
